Background: The aim of this study was to investigate the frequency of poisoning mortality in the 5-year period of 2014–2019 in Isfahan Khorshid Hospital, Iran. Materials and Methods: This study is a cross-sectional descriptive analytical study, which was performed in 2020. The demographic and clinical data about the patients were extracted from the patients' files and were then analyzed. Results: The number of deaths due to poisoning in the study period was 264, and the mean age of the deceased was 42.33 ± 20.097. One hundred and ninety-three (73.1%) patients were male. The frequency of deaths in the poisoning ward was 0.84%. The causes of death were accidental overdose (73, 26.9%), suicide (155, 63.2%), accidental use (18, 7.3%), and homicide in one patient. The mean age, time between exposure of toxin until death and history of addiction, substance use, and suicide in men patients was significantly higher than women (P < 0.05), however, such significant results were observed in married when compared with single patients. The differences between the two genders based on the type of toxic substance were statistically significant (P < 0.001). The most common causes of death were pesticides poisoning (n = 121), especially paraquat (n = 48) and Aluminum phosphide (n = 45), and multidrug poisoning (n = 48). Conclusion: In this study, we showed that the death rate due to poisoning in our center was lower than other centers. The highest number of poisoning was in men as well as married patients. It is also recommended that more serious educational and preventive strategies should be used in this regard.

Background: Acute lymphoid leukemia (ALL) is the largest subset of hematologic malignancies, accounting for approximately 70%–80% of childhood leukemia, and is most common at age 4 years. The aim of this study was to define the frequency of chromosomal abnormalities in pediatric ALL. Materials and Methods: In this 11-year retrospective study, we investigated 99 patients which referred to our department due to ALL from 2010 to 2020. The age group of the patients ranged from 6 months to 14 years with a mean of 6.71 ± 4.09 years. Clinical and diagnostic findings were extracted from patients' medical records. Results: We showed cytogenetic abnormalities of 99 pediatric ALL patients, including 78 pre-B-ALL, 9 common B-ALL, and 12 T-ALL cases. The 5-year overall survival rate (OSR) and event-free survival (EFS) of all cytogenetic abnormalities (n = 99) were 48% and 43%, respectively. There was a significant relationship between the two cytogenetic abnormalities, hypodiploidy and t(9;22), with death (P < 0.05). On comparing the subjects with normal cytogenetics to the other cytogenetic abnormalities, EFS was significantly low for hypodiploidy (P = 0.0163, hazard ratio = 0.5308) and t(9;22) (P = 0.0131, hazard ratio = 0.4908), while other cytogenetic abnormalities did not have a statistically significant difference in EFS. Conclusions: Our results emphasized the importance of the cytogenetic findings in evaluating the survival outcomes, which allows identifying a variety of OSR and EFS, because some of the cytogenetic abnormalities may interfere with the death and prognosis.

Background: Obesity, Vitamin D (VD) deficiency, and infertility are important ubiquitous issue; however, the association of obesity and serum VD levels with abnormal sperm is unclear and inconclusive. The current study investigated the correlation of obesity and serum VD levels with sperm DNA integrity and sperm parameters in normozoospermia men. Materials and Methods: Semen and blood samples from 64 men were divided into two groups: obese and nonobese men based on body mass index (BMI). Sperm motility and viability were determined by computer-aided sperm analysis and eosin-nigrosin staining. DNA fragmentation, determined by sperm chromatin dispersion method. VD concentrations were assessed by the Elisa technique. Results: Serum concentration of VD levels in the obese group was significantly lower than nonobese men (P < 0.05). Sperm motility was significantly reduced in the obese group in comparison to nonobese (P < 0.05). Rapid progressive motility was statistically lower in obese men compared with the nonobese group (P < 0.05). Sperm count and morphology were not statistically significant in both groups. Sperm viability in the nonobese group was significantly decreased in comparison to obese group (P < 0.05). DNA integrity was significantly higher in the obese group as compared with nonobese (P < 0.01). Conclusion: VD deficiency in the obese group showed decreased sperm motility, increased DNA damage, and viability. Adverse consequences of obesity and the possible effect of BMI infertility treatment must be discussed with counseling couples interested in assisted reproductive techniques outcomes, especially in men without any unknown cause.

Background: Microsatellite instability (MSI) in colorectal cancer (CRC) patients is considered as a diagnostic and prognostic marker. MSI is a consequence of mismatch repair deficiency which is evaluated using the different microsatellite markers on the whole genome. In this pilot study, the diagnostic value of a novel triplex panel including three mononucleotide markers has been evaluated in comparison to the standard Promega kit for MSI testing in CRC patients with Amsterdam II criteria. Materials and Methods: DNA extracted from tumors and normal Formalin-Fixed Paraffin-Embedded (FFPE) tissues of index cases from 37 HNPCC (Hereditary non-polyposis colorectal cancer) families were evaluated for MSI state. Primer design for three markers, including BAT25, ACVR2, and TGFBR2, was performed using 19 nucleotides of the M-13 phage. The instability of each marker was assessed through fragment analysis in comparison with Promega kit markers for all patients. The sensitivity and specificity of each marker have been calculated. Results: The comparative evaluation of MSI in both tumors and normal adjacent FFPE tissues demonstrated a separate sensitivity as 100%, 83.3%, and 76.9% for BAT25, ACVR2, and TGFBR2, respectively, and 100% sensitivity in the form of a triplex. Moreover, the specificity for each of these three markers in MSI testing was estimated as 100%, separately and in the form of the triplex in comparison with the Promega pentaplex standard Kit. Conclusions: A high sensitivity and specificity for the novel triplex panel in MSI-testing were estimated among Iranian patients. More studies are recommended to confirm this panel as a diagnostic kit for MSI testing.

Background: Glutamate is an important excitatory neurotransmitter in the pedunculopontine tegmental (PPT) nucleus. The cardiovascular effect of glutamate and its non-N-methyl-D-aspartate (NMDA) receptor in the PPT is unknown; therefore, we evaluated glutamate and its non-NMDA receptor on cardiovascular parameters in normotensive and hypotensive induced by hydralazine (HLZ) in rat. Materials and Methods: After anesthesia, the femoral artery was cannulated for recording of cardiovascular parameters. Microinjection of drugs was done stereotaxically. L-Glutamate (L-Glu) and 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) (an antagonist of nonNMDA receptor) were microinjected into the PPT in normotensive and HLZ hypotensive rats. Changes (Δ) of mean arterial pressure (MAP), systolic blood pressure (SBP), and heart rate (HR) were obtained and compared with the control group. Results: In normotensive rats, L-Glu significantly increased SBP and MAP (P < 0.001) and decreased HR (P < 0.01), whereas CNQX alone did not significantly effect. Coinjection L-Glu + CNQX significantly attenuates the cardiovascular effect of L-Glu (P < 0.05 to P < 0.01). In hypotension induced by HLZ, SBP and MAP significantly decrease but HR did not change. In HLZ groups, L-Glu significantly improves (P < 0.05) and CNQX deteriorated hypotension induced by HLZ (P < 0.05). Coinjection of L-Glu + CNQX also attenuates the effect of L-Glu on Δ MAP and Δ SBP. In hypotension, ΔHR induced by L-Glu was significantly higher than CNQX (P < 0.01). In L-Glu + CNQX group, ΔHR also was lower than L-Glu (P < 0.05). Conclusion: Our findings revealed that glutamatergic system of the PPT in both normotensive and hypotension induced by HLZ plays a pressor with bradycardic responses that partly mediated by non-NMDA receptor.

Background: This study aimed to determine the current EPIYA motifs of the cagA gene in Helicobacter pylori isolates from patients with gastric disorders, and evaluate the association between these patterns and the clinical outcome of H. pylori infection in different geographical regions of Iran. Materials and Methods: We examined 150 patients with gastrointestinal disorders from the central and eastern regions of Iran. The detection of H. pylori and screening of cagA was performed by polymerase chain reaction (PCR). The pattern of the motifs was determined by PCR followed by sequencing. Results: The overall prevalence of H. pylori was 66.3% in eastern (Mashad) and 50.6% in the central (Isfahan) part of Iran. The frequency of cagA-positive strains in Mashad and Isfahan were 63.4% and 56.7%, respectively. The pattern of EPIYA motif was as follows: 43 (79.6%) ABC, 7 (12.9%) AB, 4 (7.4%) ABCC, and one (1.9%) ABCCC. We also identified a novel EPIYA C sequence motif which showed association with gastric cancer (GC). The relationship between the frequency of specific EPIYA motifs and GC was statistically significant (P < 0.05). Conclusions: This is the first report for the determination of the cagA EPIYA motif of H. pylori in the Northeast and center of Iran. The prevalence of cagA positive H. pylori between the two regions was significant (P ≤ 0.05). All isolates of the H. pylori cagA were western type (ABC). The increase in the number of EPIYA-C repeats was associated with GC (P ≤ 0.01).

Background: Wrist function has a significant impact on quality of life, which is why restoring normal wrist movement after surgery is so important. Due to the COVID-19 pandemic, and the restrictions imposed on “face-to-face” visits, using smartphones has become more important in tracking patients. The main purpose of this study was to determine the accuracy of telemedicine in following up patients who had undergone distal radius fracture operation. Materials and Methods: From February to October 2020, 126 patients between 20 and 60 years old were randomly selected at our orthopedic trauma center. All patients were visited in person by an orthopedic surgeon in the morning (control group) and again all of them were visited online via smartphone in the evening by another orthopedic surgeon (case group). Both visits were done at regular intervals in the 2^nd, 6^th, and 12^th weeks after surgery. Patients were evaluated for extremity function outcomes and joint range of motion. Results: The two groups were similar in terms of mean Patient-Rated Wrist Evaluation score and Disabilities of the Arm, Shoulder, and Hand score and did not show a statistically significant difference (P < 0.05). There was no significant difference in wrist range of motion measurements between the two groups (in-person visits and smartphone visits) during the follow-ups (P > 0.05). Conclusion: Changes in wrist range of motion after surgery can be assessed with high accuracy using smartphone applications and this method can be considered as a proper alternative to frequent in-person visits to evaluate postsurgical wrist condition.

Background: Toxoplasmosis is a disease caused by Toxoplasma gondii, and one-third of the world's population has T. gondii antibodies. Due to this issue, the aim of this study was to assess the mean prevalence and odds ratios of T. gondii infection and epidemiological features of neonatal infection worldwide. Materials and Methods: We performed a meta-analysis and systematic review of published studies reporting T. gondii infection using the PubMed, MEDLINE, Web of Science, EMBASE, and Scopus electronic databases through January 1999 to December 2020, regarding diagnostic tests, and prevalence data of infection among the newborn population. The pooled prevalence of T. gondii with a 95% confidence interval (CI) was calculated using the random-effects models. Results: A total of thirty eligible articles were included. The estimated global prevalence rate was 44% (95% CI: 29%–0.58%); the highest prevalence rate was in America 47% (95% CI: 30%–64%), followed by Europe 41% (95% CI: 26%–57%) and Asia 33% (95% CI: 4%–61%). In this study, despite our careful analysis of possible modifiers, the heterogeneity was significant (P = 0.000). The publication bias was not significant based on the results of Egger's (P = 0.918) and Begg's tests (P = 0.230). Conclusion: Based on the results of this study, T. gondii infection can be a serious concern in newborns around the world. Therefore, further research is needed to provide better strategies to screen and diagnose T. gondii infection in neonates and determine the risk factors associated with the prevalence of infection in neonates worldwide.

Background: Considering the side effects of common drugs used to treat polycystic ovary syndrome (PCOS), researchers have turned their attention to natural compounds, including medicinal plants. Foeniculum vulgare has estrogenic properties and has been traditionally used to treat gynecological disorders. Bunium persicum has medical aspects that have not yet been evaluated, so the aim of this study was to evaluate the effects of combination therapy with these extracts on clinical symptoms of women with PCOS. Materials and Methods: In this double-blind clinical trial study, 70 women with PCOS referred to infertility clinics, were selected and randomly divided into two groups. The intervention group received B. persicum capsule 60 mg plus F. vulgare capsule 25 mg) twice daily for 4 months and the control groups received routine intervention. Before and after the intervention, levels of luteinizing hormone (LH), follicle-stimulating hormone, progesterone, prolactin, testosterone and dehydroepiandrosterone sulfate (DHEAS) levels, hirsutism score, and menstrual pattern were recorded and endometrial thickness and follicle count were determined by ultrasound. Data were analyzed by the SPSS21 software. Results: Treatment with B. persicum and F. vulgare extracts significantly decreased LH and DHEAS levels, hirsutism score, and significantly increased menstrual duration compared to the control group. Before the intervention, 5.7% of the intervention and control groups had the normal menstrual pattern, while after the intervention 31.4% of the intervention group and 25.7% of the control group had the normal pattern. Conclusion: Regarding the effect of these extracts combination and because they have no side-effects, which is a great advantage over chemical drugs, using of these plants recommend.

Background: Obesity hypoventilation syndrome (OHS) is associated with increased mechanical load on respiratory system. Here, we aimed to investigate and evaluate the effects of noninvasive ventilation (NIV) on physical and mental status of patients with OHS. Materials and Methods: The current study is an observational study that was performed in 2020 on 50 patients with OHS in Isfahan, Iran. Beck's Depression Inventory (BDI-II) and Hospital Anxiety and Depression Scale (HADS) questionnaires were also filled for all patients assessing their depression levels that were confirmed by psychiatrists. PO₂ and PCO₂ of patients were evaluated using venous blood gas (VBG) before interventions. Patients with a definite diagnosis of OHS and depression entered the study and underwent treatments with NIV. One month after the interventions with NIV, the blood gases of patients were evaluated using VBG and BDI-II, and HADS questionnaires were also filled for all patients, evaluating their depression. Results: The mean age of the subjects was 63.5 ± 13.5. The mean blood oxygen after the use of NIV in patients with OHS increased significantly (P = 0.001). The mean of carbon dioxide after using NIV in patients with OHS decreased significantly (P = 0.001). Based on the BDI-II and HADS scales, the mean score of depression after using NIV decreased significantly (P = 0.001 for both). Conclusion: NIV therapies are associated with improvements in blood oxygen and CO₂ of patients with OHS. The levels of depression also decreased after treatments that were confirmed by psychiatrists.

Background: Toxocariasis is a parasitic disease caused by the larval stage of Toxocara canis and Toxocara cati. Infective stage of this parasite for human develops on soil. So, in this work contamination of the soil of public environments in five geographical areas of Isfahan province of Iran has been investigated. Materials and Methods: In this descriptive study, 355 soil samples were collected from parks, children's playgrounds, student dormitories, and university environments, and examined by Flotation method. The samples were then inspected using microscopic and molecular methods. Results: From the 355 examined soil samples in 77 (21.69%), and 87 (24.50%) cases Toxocara eggs were detected by microscopic and molecular methods, respectively. In the molecular method, 31 (8.70%) cases of T. cati and 44 (12.39%) cases of T. canis were identified. Conclusion: Toxocara eggs were identified in all areas of Isfahan province, although contamination rate was higher in Fereydun Shahr and Semirum counties.

Background: Cataract surgery is one of the most common eye surgeries, which is currently performed under topical anesthesia using sedative medications. Dexmedetomidine and acetaminophen are good candidates for analgesia in other circumstances, however, this study aimed to evaluate the effect of dexmedetomidine or acetaminophen infusion and normal saline (NS) alone compared with the control group on the severity of pain in cataract surgery. Materials and Methods: In this parallel randomized controlled clinical trial, the effect of dexmedetomidine or acetaminophen infusion and NS on level of pain, vital signs, recovery status, and surgeon satisfaction during cataract surgery were assessed. One hundred and thirty-five patients between the age of 50–80 years undergoing cataract surgery were recruited on a consecutive basis and randomized into three groups receiving acetaminophen (15 mg/kg), dexmedetomidine (0.5 μgr/kg), and NS. Baseline vital signs, blood pressure, arterial oxygen saturation, respiratory and heart rate at certain time-points including the start of surgery, 5, 10, and 15 min after surgery, after arrival to the recovery room, 20, 40, 60 min after recovery were measured. Pain intensity and drugs side effects were also recorded after surgery. Results: Level of respiratory depression was higher in patients receiving dexmedetomidine. Heart rate and oxygen saturation percentage had no significant differences in the three groups as well as pain intensity. Conclusions: Acetaminophen was as effective as dexmedetomidine with lower side effects and higher surgeons' satisfaction, without any interference with cardiovascular and respiratory parameters. Acetaminophen infusion should be considered as an acceptable analgesic drug for cataract surgery.

Prurigo pigmentosa (PP) is a rare skin disorder presenting as erythematous urticarial papules on the chest and leaving reticulated pigmentation. Although the etiology of PP is unknown, conditions associated with ketosis such as diabetes mellitus, ketogenic diet (KD), and anorexia nervosa are implicated. Herein, we report a 21-year-old woman who developed PP after adhering to a KD and responded to resuming a regular diet.

Background: Fecal incontinence (FI) is a common disorder that affects the psychological, social, and mental aspects in children. It was showed that the quality of life (QoL) in children with FI was in low level. Bowel management program (BMP) is one of the most effective and low-cost therapies in selected children with FI, but it has also significant effects on mental functions. This study was conducted to evaluate the impact of BMP on the QoL of children with FI. Materials and Methods: In a case series study, we prospectively included all school-age children suffering from FI who had visited in colorectal follow-up center of Isfahan University of Medical Sciences. Patient eligibility included children with FI between 8 and 12 years who were candidate of BMP. The QoL was assessed by Persian version of pediatric QoL (PedsQL) 4.0. Results: In this study, 24 children with FI were studied. Our results showed that total QoL score is significantly different after BMP. The mean score of physical performance before and after BMP was significantly different (P = 0.02). In terms of emotional performance, the mean score of this dimension before and after starting of BMP was significantly different (P = 0.06). In terms of social performance, the mean score of this dimension before and after starting of BMP was significantly different (P = 0.008). Conclusion: BMP is a low-cost and affordable treatment that can have a significant impact on improving the QoL of the child by improving intestinal function.

Background: Melanoma is skin cancer, and the treatments are not efficient enough. Therefore, finding new drugs seems to be an essential need. Vanillin, which is extracted from vanilla seed, has anti-cancer effects by reducing nuclear factor-κB (NF). We explored the anti-tumor effects of vanillin in the melanoma model and its possible mechanism. Materials and Methods: In the MTT assay, mice melanoma cells (B16F10) were treated with vanillin (1, 2, 3, 4, 5 μg/mL) for 24 and 48 h. In an animal model, B16F10 was subcutaneously injected into C57BL/6 mice. After the development of tumors, the mice were treated with 50 and 100 mg/kg/day of vanillin for 10 days. The tumor size and expression level of NF-κB protein were measured. Results: In the MTT assay, vanillin in all concentrations significantly decreased B16F10 cell viability after 24 h incubation. The size of melanoma tumors was reduced in both doses 50 and 100 mg/kg/day in mice. NF-κB protein expression was decreased in the 100 mg/kg/day group in comparison with the control group. Conclusion: We found that vanillin by reducing NF-κB expression may have anti-tumor effects and reduced melanoma tumor size and cell viability.

Background: Due to the contradictory results of the effects of Vitamin B6 in reducing the hematotoxic effects of linezolid, the present study aimed to investigate the possible role of Vitamin B6 administration in reducing linezolid-related hematological toxicities in patients with chronic osteomyelitis. Materials and Methods: In a randomized double-blind placebo-controlled clinical trial, patients with chronic osteomyelitis were randomly divided into two groups (n = 40 each): the intervention group received Vitamin B₆ 40 mg twice daily from the beginning of treatment with linezolid and the control group received placebo with linezolid, both for 21 days. Blood variables including hemoglobin (Hb), white blood cells (WBC), and platelets (PLT) were measured at baseline and at the end of the 1^st, 2^nd, and 3^rd weeks (days 7, 14, and 21) of the intervention. Results: There was no significant difference between the groups regarding the count of WBC and PLT and level of Hb at evaluated time points. Furthermore, there was a significant decreasing trend in all parameters within both groups; however, the decreasing trend of both PLT and WBC was slower in the intervention (Vitamin B6) group compared to the placebo group. Conclusion: Vitamin B6 has no significant effect in the reduction of hematological adverse effects of linezolid in chronic osteomyelitis patients. However, it could retard the decreasing trend of WBC and PLT counts.

Background: There are several methods to control pain, especially in traumatic patients with rib fractures. Intrapleural analgesia (IPA) and intercostal block methods are recommended in patients with rib fractures to control pain. Here, we aimed to evaluate and compare the effects of IPA and intercostal block on patients' clinical conditions. Materials and Methods: This is a randomized clinical trial that was performed in 2020–2021 on thirty traumatic patients with rib fractures. We collected the results of arterial blood gas in all patients before interventions including HCO3, pH, pO2, and pCO2 and also evaluated pain of patients. The first group underwent intercostal blockade with standard method with bupivacaine, and for the second group of patients, a chest tube was implanted. Patients were monitored for up to 12 h for pain intensity and need for analgesics. Results: The mean levels of HCO3 decreased in both groups after the interventions, and this decrease was more significant in patients in the intercostal blockade group (P < 0.05). The mean levels of pO2 increased in both groups after interventions, especially in patients in the intercostal blockade group (P < 0.05). The mean pCO2 levels also decreased in both groups (P < 0.05). The mean pain intensity in both groups decreased significantly after the intervention (P < 0.05) and also the mean pain intensity in the intercostal blocking group decreased significantly more than the group treated with chest tube (P < 0.05). Conclusion: Intercostal blockade through bupivacaine is more effective than chest tube administration of bupivacaine in patients with rib fractures.

Background: Hysterectomy is one of the most common gynecology surgeries. This study aimed to compare perioperative bleeding in transabdominal and transvaginal hysterectomy. Materials and Methods: This prospective, double-blind, randomized, controlled clinical trial was performed on 80 patients undergoing hysterectomy referred to Shahid Beheshti Hospital, Isfahan, Iran. Patients were divided into two groups of 40; the first group (T) received 1 g intravenous tranexamic acid (TXA) for 20 min preoperatively. The second group (S) received 10 cc normal saline as placebo. Blood samples were taken before and 12 h after surgery for assessment of hemoglobin, hematocrit, and platelet count, the prothrombin time, activated partial thromboplastin time, and serum creatinine as well as volume of blood transfusion. Results: There were no significant differences between the two groups in heart rate, diastolic blood pressure (BP), systolic BP, and mean arterial pressure before, during, and after surgery (P > 0.05). There was no significant difference in blood variables before and after surgery (P > 0.05) except the platelet count that was in the normal range in both groups after surgery (P = 0.022). The mean volume of blood transfused in the case group was significantly lower than the control group during surgery (P = 0.008) and 12 h after surgery (P = 0.01). Conclusion: The prophylactic administration of TXA results in a significant reduction in need for blood transfusion and the duration of surgery. Given the lower risks of using TXA compared to the other drugs, it is recommended in hysterectomy to control bleeding.

Background: Sjogren's syndrome, as a chronic autoimmune disease, involves in lymphocytic infiltration in the exocrine glands. As the result of exocrine glands disruption, the clinical hallmark of this disease including dryness of mouth and eyes along with fatigue and joint pain occur. However, heterogeneity of clinical presentations among newly diagnosed adult patients with Sjogren's syndrome leads to difficulty in its diagnosis. One of the diagnostic criteria for Sjogren's syndrome is the presence of autoantibodies in patient serum. One of the novel biomarkers suggested for diagnosis of Sjogren is alpha-fodrin antibody. In this study, we aimed to evaluate the diagnostic power of anti-α-fodrin antibody among the Iranian population for the first time. Materials and Methods: We recruited 82 individuals in this study. Alpha-fodrin were measured in case and control with Elisa kit as 16.71 (9.84) and 18.44 (11.54). Results: There was no any significant difference between two groups regarding alpha-fodrin level (P = 0.35). Then we applied the receiver operating characteristic (ROC) curve analysis to determine the predictive value of alpha-fodrin for diagnosing Sjogren's disease. The area under curve of the ROC curve was calculated as 0.5453. Also, there were significant association between age and alpha-fodrin antibody. Conclusions: Alpha-fodrin test did not have acceptable predictive power for predicting Sjogren's disease; however, it could be associated with disease progression.

As a family of short noncoding RNAs, MicroRNAs have been identified as possible biomarkers for cancer discovery and assist in therapy control due to their epigenetic involvement in gene expression and other cellular biological processes. In the present review, the evidence for reaching the clinical effect and the molecular mechanism of miR-942 in various kinds of cancer is amassed. Dysregulation of miR-942 amounts in different kinds of malignancies, as bladder cancer, esophageal squamous cell carcinoma, breast cancer, cervical cancer, gastric cancer, colorectal cancer, Kaposi's sarcoma, melanoma, Hepatocellular carcinoma, nonsmall-cell lung cancer, oral squamous cell carcinoma, osteosarcoma, ovarian cancer, pancreatic ductal adenocarcinoma, renal cell carcinoma, and prostate cancer has stated a considerable increase or decrease in its level indicating its function as oncogene or tumor suppressor. MiR-942 is included in cell proliferation, migration, and invasion through cell cycle pathways, including pathways of transforming growth factor-beta signaling pathways, Wnt pathway, JAK/STAT pathway, PI3K/AKT pathway, apoptosis pathway, hippo signaling pathway, lectin pathway, interferon-gamma signaling, signaling by G-protein coupled receptor, developmental genes, nuclear factor-kappa B pathway, Mesodermal commitment pathway, and T-cell receptor signaling in cancer. An important biomarker, MiR-942 is a potential candidate for prediction in several cancers. The present investigation introduced miR-942 as a prognostic marker for early discovery of tumor progression, metastasis, and development.

Background: Due to chronic respiratory and gastrointestinal problems, growth failure is a common issue in patients with cystic fibrosis (CF). The present study aimed to investigate the prevalence of growth hormone deficiency (GHD) in CF children with stable gastrointestinal and respiratory conditions. Materials and Methods: In this study, the growth indicators of all 4–16-year-old children referred to two CF clinics were monitored over 3 years. Children without severe gastrointestinal or pulmonary symptoms with weight <3% percentile or whose height increase were two standard deviations below their expected height growth over 6 months were selected for the growth hormone (GH) stimulation test by clonidine and L-dopa test. Some of the children without CF, who were also referred for height growth disorders and matched the CF group, were considered the control group. They underwent the GH stimulation test, and the results were compared. Results: From 150 patients with CF, growth failure was observed in 24 patients with stable gastrointestinal and respiratory conditions; in 10 of them, the GH stimulation test was deficient. The prevalence of GHD was 6.6% in CF patients. In the control group of 30 children without CF, but with growth failure, the GH was deficient in nine cases, implying no significant difference with the case group (P = 0.37). Conclusion: In our study, the prevalence of GHD was 6.6% in CF patients, whereas the prevalence GHD in the normal population of childhood is <1%. Therefore, further studies should be designed to investigate the cause of GHD in CF patients.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a major complication of many chemotherapeutic agents, including taxanes. Here, we aimed to investigate the effect of zinc on CIPN. Materials and Methods: This is a double-blinded controlled clinical trial that was performed in 2020–2021 in Isfahan on 55 cancer patients. We collected the data regarding CIPN, its severity, presence of abnormal deep-tendon reflexes, paresthesia, restriction in daily activities, and restriction in self-care and pain. Patients were divided into two groups: Patients in the first group were treated with capsules of zinc sulfate 25 mg daily and the control group received placebo. The duration of treatments was 3 months. Patients were visited 6, 9, and 12 weeks after study initiation. Results: There was a statistically significant decrease in the frequency of CIPN in the intervention group (37.03% vs. 14.8%, P < 0.001). The evaluation of the severity of neuropathy and presence of abnormal deep-tendon reflexes also demonstrated significant decrease in the intervention group during the study (P < 0.001 for both), but no significant changes were observed in the placebo group (P > 0.05). The activity limitations and pain severity improved significantly both in the intervention and placebo groups (P < 0.001 for both groups and items). The intervention group, however, had significantly lower frequencies of activity limitation and lower pain severity within compared to the control group during the study (P < 0.0 01). Conclusion: Zinc supplement therapy resulted in reduced frequency and intensity of CIPN in patients undergoing chemotherapy with taxanes.

Background: This study investigated the effect of central administration of α-pinene and the interaction of α-pinene with GABAA receptor on pulpal nociception-induced changes in learning and memory performances in rats. Materials and Methods: Sixty-six adult male Wistar rats were used. Pulpal nociception was induced by intradental application of capsaicin (100 μg/rat). α-pinene (0.1, 0.2, and 0.4 μg/rat) was injected centrally 10 min before the administration of capsaicin. In addition, α-pinene (0.4 μg/rat) was co-injected with bicuculline (0.5 μg/rat). Spatial and passive avoidance learning and memory were assessed using Morris water maze (MWM) and shuttle box tasks, respectively. Results: Experimental results of the MWM test showed that capsaicin increases escape latency and distance traveled to the hidden platform (P < 0.01). The effect was prohibited by α-pinene at the dose of 0.4 μg/rat. Moreover, capsaicin-treated animals spent less time in the target zone than capsaicin + α-pinene (0.4 μg/rat)-treated rats (P < 0.05). In the shuttle box test, α-pinene (0.2 μg and 0.4 μg) prevented an increased number of acquisition trials and time spent in the dark chamber induced by capsaicin, whereas it increased step-through latency (P < 0.01). However, the effects of α-pinene (0.4 μg/rat) in both tests were prohibited by bicuculline (0.5 μg/rat). Conclusion: The data showed that central administration of α-pinene might reduce pulpalgia-induced learning and memory impairment, at least partially, via modulation of GABA_A receptors.

Background: Marine organisms such as seaweeds, produce potent chemicals with characteristic biological features. Sargassum species have great potential to be used for neuronal protection as part of nutraceuticals. The aim was to investigate the effects of hexane and methanol extracts of Sargassum plagyophylum from the Persian Gulf on depression induced by interferon-α (IFNa) in mice. Materials and Methods: S. plagyophylum was extracted by maceration with methanol-ethyl acetate solvent (1:1). The extract was evaporated and partitioned by hexane and methanol solvents. Male mice were used, depression was induced by SC injecting IFNα (16 × 10 ^{5 IU}/kg) for 6 days. Animals were subject to the forced swimming test (FST) after the locomotor test, on day 7. The extracts were administered IP either one single dose (acute) before the test, or simultaneously with IFNα (sub-acute). Results: The locomotor activity was not different from control values. IFNa increased the immobility time during FST (140 ± 14 s vs. control group 95 ± 9 s, P < 0.05). Hexane extract acute (40 mg/kg) injection was not effective while its sub-acute (20 mg/kg) injection reduced immobility time (46 ± 8 s, P < 0.001 vs. IFNa alone). Methanol extract acute (20 mg/kg) and sub-acute (20 mg/kg) administration significantly reduced immobility during the FST (78 ± 20 s, and 72 ± 8 s respectively, P < 0.05 vs. IFNa alone). Conclusion: S. plagyophylum has antidepressant effects, the hexane extract could prevent depression while the methanol extract not only prevented but also treated depression induced by IFNa in mice. Since this species is abundant in the Persian Gulf further clinical studies on its psychological effects are warranted.

Background: The coronavirus disease (COVID-19) pandemic has made a great impact on health-care services. The prognosis of the severity of the disease help reduces mortality by prioritizing the allocation of hospital resources. Early mortality prediction of this disease through paramount biomarkers is the main aim of this study. Materials and Methods: In this retrospective study, a total of 205 confirmed COVID-19 patients hospitalized from June 2020 to March 2021 were included. Demographic data, important blood biomarkers levels, and patient outcomes were investigated using the machine learning and statistical tools. Results: Random forests, as the best model of mortality prediction, (Matthews correlation coefficient = 0.514), were employed to find the most relevant dataset feature associated with mortality. Aspartate aminotransferase (AST) and blood urea nitrogen (BUN) were identified as important death-related features. The decision tree method was identified the cutoff value of BUN >47 mg/dL and AST >44 U/L as decision boundaries of mortality (sensitivity = 0.4). Data mining results were compared with those obtained through the statistical tests. Statistical analyses were also determined these two factors as the most significant ones with P values of 4.4 × 10⁻⁷ and 1.6 × 10⁻⁶, respectively. The demographic trait of age and some hematological (thrombocytopenia, increased white blood cell count, neutrophils [%], RDW-CV and RDW-SD), and blood serum changes (increased creatinine, potassium, and alanine aminotransferase) were also specified as mortality-related features (P < 0.05). Conclusions: These results could be useful to physicians for the timely detection of COVID-19 patients with a higher risk of mortality and better management of hospital resources.

Background: This study aimed to compare the efficacy of gabapentin and oxazepam on sleep quality, the severity of anxiety, and pain level in patients admitted to the coronary care unit (CCU). Materials and Methods: This double-blind randomized clinical trial was done on the patients with unstable angina (UA) admitted to the CCU of Hazrat Rasool Akram Hospital in Tehran. A total of 56 patients were entered the study and randomly divided into two groups of 26. The first group was given a gabapentin capsule at a dose of 300–1200 mg/day, and the second group was given 10–20 mg of oxazepam tablets per day until hospitalization in the CCU. On the first and 4^th days of hospitalization, Groningen sleep quality score (GSQS), Beck Anxiety Inventory, and severity of pain experienced by Visual Analogue Scale were recorded, and the mean frequency of chest pains was calculated in 24 h during the first 4 days. The amount of drug (morphine) prescription in CCU also compared between the two groups. Results: There was no significant difference in GSQS scores between both groups. The mean score of Beck's anxiety scale did not differ significantly between the two groups. However, the incidence of chest pain was significantly lower in the gabapentin-receiving group than in the oxazepam-receiving group (<0.001). The days that the patients experienced chest pain were significantly less in the gabapentin-receiving group than in the oxazepam-receiving group (<0.001). Conclusion: The results of our study showed that gabapentin compared to oxazepam could significantly reduce chest pain in patients with UA.

Background: Green synthesized silver nanoparticles (AgNPs) have been used in a wide range of biological applications, including their use as antimicrobial agents. The aim of this study was to evaluate the antibacterial activity of green synthesis AgNPs using nisin against Pseudomonas aeruginosa (P. aeruginosa). Materials and Methods: In order to synthesize Ag-nisin, a 1 mg/ml nisin solution was mixed with a 1-mM silver nitrate solution and incubated. The Fourier transform infrared spectroscopy (FTIR) analysis was employed to determine the presence of various biomolecules around AgNPs. The AgNPs were morphologically observed and characterized using field emission scanning electron microscopy assessment, dynamic light scattering (DLS), and zeta potential analysis. The microdilution broth method based on CLSI principles was used for the assessment of the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of nisin on P. aeruginosa isolates. Results: Field emission scanning electron microscope showed spherical shaped nanoparticles. DLS revealed that the average size of nanoparticles was 37.2 nm. The zeta potential of AgNPs was − 13.3 mV. FTIR findings revealed that nitrogen atoms of nisin's amine and amide groups are responsible for the capping and stability of the nanoparticles. The MIC and MBC showed that Ag/nisin nanoparticles had higher antimicrobial activity than nisin or AgNPs alone. Conclusion: The findings of this study show that the antibacterial activity of nisin can be increased by assembling it into the AgNP interface using a green chemical synthesis method. As a result, the technique may be used to develop an antibacterial formulation to enhance the effectiveness of nisin.

Since the main role in the pathogenesis of the coronavirus is attributed to the angiotensin-converting enzyme (ACE) receptor, it could possibly be a hypothesis in the differential sex-based pathogenesis of the coronavirus. The virus inserts its genetic material into the cell through its ACE2 receptors and replicates it by intracellular proteins. ACE2 receptors are highly expressed in cell membranes of various tissues in the body, including cardiovascular, gastrointestinal, renal, macrophage cells, and especially on the surface of type 2 pneumocytes in the lungs, ovaries, uterus, vagina, placenta, and testes. Therefore, cells having a higher expression of the ACE2 may be a specific target for coronavirus binding and infectivity. Due to the increase of infections in males, concerns have been appeared about the potential impact of coronavirus disease 2019 (COVID-19) on their fertility and reproductive organs. Thus, it is necessary to investigate if COVID-19 disturbs female and male fertility, so this review aimed to study the comprehensive evidences on the association of COVID-19 with human reproduction.

Insulin resistance (IR) is a chronic pathological condition that is related to reduce the rates of glucose uptake, especially in the liver, muscle, and adipose tissue as target tissues. Metabolic syndrome and type 2 diabetes mellitus can occur following progression of the disease. The majority of prior research has applied that some cations such as magnesium (Mg²⁺) have important physiological role in insulin metabolism. Mg²⁺ is the fourth most abundant mineral in the human body that gets involved as a cofactor of various enzymes in several metabolic events, such as carbohydrate oxidation, and it has a fundamental role in glucose transporting mechanism of the cell membrane. This cation has numerous duties in the human body such as regulation of insulin secretion in pancreatic beta-cells and phosphorylation of the insulin receptors in target cells and also gets involved in other downstream signal kinases as intracellular cation. On this basis, intracellular Mg²⁺ balancing is vital for adequate carbohydrate metabolism. This paper summarizes the present knowledge about the therapeutic effects of Mg²⁺ in reducing IR in liver, muscle, and pancreases with different mechanisms. For this, the search was performed in Google Scholar, PubMed, Scopus, and Web of Science by insulin resistance, skeletal muscle, liver, pancreases, magnesium, Mg²⁺, and inflammation keywords.

Background: The aim of the study is to identify latent class (LC)-derived patterns of women's knowledge, attitude, and practice (KAP) toward coronavirus disease 2019 (COVID-19) in Iran. Materials and Methods: This cross-sectional survey of 2029 women, who participated in the PERSIAN Birth Cohort, was conducted in Isfahan, Iran. KAP was assessed by shortened and validated form of a recently used questionnaire in Iran. LC analysis was used to discover underlying response patterns of KAP toward COVID-19 using Mplus 8.0 software. Results: Three classes were identified: Class 1 (n = 514, 25.33%) “Low knowledge and poor practice, Class 2 (n = 423, 22.08%) “Moderate knowledge and proper practice,” and Class 3 (n = 1092, 53.82%) “Low knowledge and proper practice.” The lowest rate of positive attitude was seen in Class 3. Women living in rural areas, as well as those with lower education, were more likely to member classes with improper practice. Conclusion: The findings suggest that the LCA approach can provide important information reflecting different levels of adoption of protection toward COVID-19 infection. The results may be useful to conducting health-care programs during the outbreaks.

Background: The aim of this study was to investigate the relationship between body mass index (BMI) and depression, anxiety, body image, and eating attitudes in 12- to 16-year-old adolescents. Materials and Methods: In this descriptive-analytical study on 437 students in Shahrekord, Iran, selected by two-step random sampling (selection of schools and students), participants were divided into normal weight (BMI: 5–85^th), overweight (BMI: 85–95^th), and obese (BMI >95^th) groups and completed the questionnaires and data were analyzed by SPSS version 23. Results: BMI had a positive correlation with anxiety, depression, and dysfunctional eating attitudes, and negative correlation with body image in adolescents. Mean scores of depression and anxiety in both overweight and obese groups were significantly higher than those in normal weight adolescents but scores of body image and eating attitudes were not different between overweight and normal weight groups. Conclusion: Obesity and overweight may have adverse effects on mental health of adolescents and more attention to psychological aspect of obesity can help us to provide better health services to overweight and obese adolescents.

Background: Hepatopulmonary syndrome (HPS) is one of the complications of advanced cirrhosis which has a serious impact on prognosis of patient. Finding arterial deoxygenation early and initiating higher-level treatment is one of the most critical strategies in the therapy of HPS. In this study, we aimed to assess the utility of six-minute walk test (6MWT) in the diagnosis of HPS. Materials and Methods: We have enrolled 100 consecutive cirrhosis patients referred to the Liver Clinic of a tertiary care centre of India for >1 year. The Child-Pugh score and the MELD score were used to determine the severity of cirrhosis. All the patients underwent transthoracic contrast echocardiography, arterial blood gas measurements on room air, 6MWT, and chest imaging. Results: A total of 100 patients were included in the study after fulfilling the inclusion criteria. HPS was present in 21 out of 100 patients (21%). Median (twenty fifth to seventy fifth percentile) MELD score in patients with HPS was 29 (26–33), which was significantly higher as compared to patients without HPS 22 (14.5–26); P <.0001. The 6MWT was positive in 20 (95.23%) HPS patients, while only 1 patient (4.77%) of HPS had negative 6MWT. If 6MWT is positive, then there was 76.92% probability of HPS and if 6MWT is negative, then 98.65% chances of no HPS. Conclusion: The 6MWT is a simple and effective screening test for HPS, it helps in identifying the patients early who have a potential to deteriorate. This simple intervention would help in prioritizing patients for liver transplantation as liver transplant is the only effective treatment for HPS.

Background: The present study evaluated the effect of internal mesh fixation and external fixation (inguinal hernia truss) on postoperative complications in patients with inguinal hernia. Materials and Methods: This randomized clinical trial was performed on 64 patients that were candidates for inguinal hernia repair by laparoscopic method following the totally extraperitoneal procedure. These patients were randomly divided into two groups. In the first group, the mesh was fixed with a maximum of three absorbable tacks. In the second group, the inguinal hernia truss was used as the external fixation for 6 weeks immediately after the surgery. Results: The results revealed that seroma, neuralgia, and recurrence were observed with the values of 6.4%, 19.4%, and 3.2% in Group A and 3.3%, 13.3%, and 3.3% in Group B (P > 0.05). Moreover, patients' pain scores 1 week and 1 month after the surgery in Group B were significantly lower than those of Group A (P < 0.05). However, the mean pain score of patients was not different between the two groups 3 and 6 months after the surgery (P > 0.05). Furthermore, the duration of return to work in Group B with an average of 8.07 ± 3.09 days was less than that of Group A with the average of 9.65 ± 5.34 days (P > 0.05). Conclusion: The mentioned findings can trigger the use of external fixation and an inguinal hernia truss as a support for the abdominal wall to make the dream of not using a foreign body in the human body come true.

Background: Previous studies have reported that gastrectomy and fundectomy can induce osteopenia. Body fat index is a new index of obesity that shows central obesity and other risks of obesity. Sleeve gastrectomy (SG) is a bariatric surgery and a new technique introduced as subsleeve, which only resected fundus of the stomach. In this study, it has been shown the effect of subsleeve and SG on fat index and bone densitometry in an animal model. Materials and Methods: Rabbits were underlined SG, fundectomy (surgical removal of fundus), or sham-operated (controls without any resection), and after 12 weeks, fat index and bone densitometry were obtained. Results: Our study showed that there was no significant difference between SG and fundectomy groups in bone mass density and fat mass after surgery in comparison with presurgery condition. SG group were associated with lower fat index and bone density, and it showed significantly decrease in weight after 1.5 months. Conclusion: Sub-SG did not show any significant effect on fat index and bone densitometry in comparison with SG. However, we found lower fat index in sleeve group of rabbits, but it was not statistically significant.

Background: Osteoarthritis is one of the most common rheumatological diseases and is also considered as one of the causes of myofascial trigger points (MtrPs). Dry needling (DN) is one of the methods used for the treatment of the MtrPs. The aim of the current study was to investigate the effects of DN on pain in participants with knee osteoarthritis (KOA). Materials and Methods: In this before and after preliminary clinical trial study, patients with mild to moderate KOA were enrolled. In one session, after determining the location of trigger points in quadriceps and gastrocnemius muscles, the patients underwent DN. The pain was evaluated at baseline, by passing 4 days and 1 month from the intervention using the Visual Analog Scale (VAS). Results: Sixteen patients with a mean age of 56.5 (4.53) years old have completed the study and follow-up period. According to the ANOVA analysis, VAS values indicated a significant decrease in pain score at the 4^th and 1 month after the intervention compared to baseline (P < 0.001). There was no significant difference between VAS at the 4^th day of intervention and also 1 month later of intervention (P = 0.087). Conclusion: The application of one session DN can lead to improvement in pain intensity in participants with mild to moderate KOA.

Background: Hypertension may lead to notifying adverse perinatal events that should be diagnosed and managed precisely. This study aims to investigate the values of cerebroplacental ration for the prediction of adverse perinatal events in hypertensive disorders of pregnancy. Materials and Methods: The current descriptive-comparative study has been conducted on 100 singleton pregnant women with the diagnosis of preeclampsia or pregnancy-induced hypertension. The Cerebroplacental ratio (CPR) was measured for the included population and divided into normal and abnormal ranges of >1 and ≤1. The adverse perinatal outcomes, including abnormal 5 min APGAR, low birth weight, perinatal death, neonatal intensive care unit (NICU) admission, academia, seizure, emergency cesarean delivery, and Tchirikov index as the general manifestation of adverse perinatal outcomes were compared between the groups. The specificity, sensitivity, positive predictive value, negative predictive value (NPV), and accuracy were measured for the adverse perinatal outcomes. Results: The two groups were remarkably different in terms of 5 min APGAR, low birth weight, cesarean section delivery, and Tchirikov index (P < 0.05). The specificity of CPR for prediction of small-for-gestational age, poor APGAR, requirement of assisted respiration, academia, Tchirikov score and NICU admission was 93.1%, 93.1%, 67.1%, 91.8%, 71.2%, and 63%, and its sensitivity was 26%, 14.8%, 51.8%, 14.8%, 51.8%, and 37%, respectively. Conclusion: CPR seems to be an appropriate means for the prediction of adverse perinatal outcomes with diversity in the prediction values of different determinants of adverse perinatal outcomes; however, in general, it had sensitivity, specificity, PP, NPV, and accuracy of 51.8%, 71.2%, 40%, 80%, and 66%, respectively.

Background: Diabetes mellitus patients are more likely to undergo nontraumatic foot or leg amputations because they have decreased circulation to the feet or reduced sensation. This condition may cause ulcerations, infections, and delayed wound healing, leading to amputations. Adequate knowledge and practices regarding foot care will be vital in the prevention of diabetic foot complications. Hence, this study aimed to determine the level of knowledge and practices of foot care among diabetes mellitus patients attending a rural primary health center in Belagavi-South India. Materials and Methods: A cross-sectional study was conducted in the rural field practice area of J.N. Medical College, Belagavi, for 7 months (November 2019 to May 2020). A pretested questionnaire was administered to 461 diabetes patients attending the health center. A written informed consent was obtained from each participant. They were interviewed with a questionnaire consisting of 15 “yes” or “no” questions, each on foot care knowledge and practice. Results: The mean age of the study participants was 50.28 ± 9.48 years. The mean duration of diabetes was 10.69 ± 7.09 years. Majority, i.e., 296 (64.2%) participants showed satisfactory knowledge and 293 (63.6%) showed satisfactory practice. Only 97 (21%) had poor knowledge, 90 (19.5%) had poor practice, 68 (14.8%) patients had good knowledge, and 78 (16.9%) had good practice about diabetic foot care. Conclusions: The low level of knowledge and practice in patients with diabetes regarding foot care necessitates an educational program to increase awareness related to foot complications of diabetes, thereby motivating diabetic patients to incorporate foot care practices in their day-to-day routine.

Background: Nausea and vomiting is a common complication after gynecological surgeries, especially laparoscopy, which can lead to discomfort and restlessness in the patients. The aim of the study was to compare the effect of ondansetron–dexamethasone and metoclopramide–dexamethasone on postoperative nausea and vomiting following gynecological laparoscopy. Materials and Methods: In this double-blind clinical trial, 68 females scheduled for gynecological laparoscopy and age range of 18–40 years were randomly divided into two groups. Group OD received ondansetron 4 mg plus dexamethasone 8 mg and group MD received metoclopramide 10 mg plus dexamethasone 8 mg, 15 min before the end of surgery. The incidence of nausea and vomiting and need for rescue medication was assessed during the recovery period, as well as at 2, 4, 6, 12, and 24 h after surgery. The data were analyzed using STATA software version 12 and a significance level of <0.05 was considered in this research. Results: The incidence of nausea in ondansetron and metoclopramide groups was 23.3% and 33.3%, respectively, and the frequency of vomiting was 10% and 16.6%, respectively, which showed no significant difference (P > 0.05). The highest incidence of nausea and vomiting in patients belonged to the metoclopramide group inside 4–6 h after surgery. Conclusion: Our study showed that no significant difference was observed in the incidence of nausea and vomiting between ondansetron–dexamethasone and metoclopramide–dexamethasone groups following laparoscopic gynecological surgery; however, the number of patients with nausea and vomiting was lower in the ondansetron–dexamethasone group.

Background: Migraine, one of the most common headaches in children, has a significant impact on children and their family's quality of life (QoL). There are two approaches for controlling migraine headaches preventative and controlling acute attacks. Several drugs have been used for this purpose, and tricyclic antidepressants were at the top. Amitriptyline has shown not only a desirable effect on controlling the headaches but also some adverse side effects. Recently, finding effective drugs with fewer side effects, become more critical. Among them, nutraceuticals were one of the promising ones. Materials and Methods: In this randomized clinical trial on 72 patients aged 5–15 years old with diagnosis of migraine based on the International Headache Society criteria, we compare the effectiveness of coenzyme Qten on frequency, duration, and severity of childhood migraine. For comparing the QoL, we used the International PedMIDAS questionnaire. Results: Coenzyme Qten showed good therapeutic effects in children, especially in long-term use; however, amitriptyline showed more rapid response. After 3 months of treatment, clinical outcomes in the two groups did not significantly differ from each other. Similarly, Children's QoL increased in the same way. There are more reported side effects in children using amitriptyline compared to coenzyme Qten. Conclusions: According to results, Co-enzyme Q10, with fewer side effects and comparable therapeutic effects, especially in the long term, could be a good drug for prophylactic treatment of migraine headaches.

Background: The present study investigated the prevalence of illness anxiety disorder and its relationship with social health in the elderly population. Materials and Methods: This cross-sectional study was conducted on 400 elderly people in Isfahan referred to the educational health service in 2020. In addition to demographic characteristics, they answered the 36-item Evans hypochondriasis questionnaire and the 28-item social health questionnaire. Results: Four hundred elderly participants with a mean age of 68.1 ± 6.6 (range: 60–89) were included in the study. One hundred and ninety-nine (49.8%) were female and 201 (50.3%) were male. Only 24.3% of the geriatrics were in the healthy group and 21.2% in the borderline category. Seventy-two of the geriatric population (18%) had poor social health and 299 of this population (74.8%) had moderate social health, and the social health status of 29 elderlies (7.3%) was favorable. There was an inverse relationship between hypochondriasis score and total social health score and its dimensions (P < 0.05). Conclusion: High prevalence of hypochondriasis was observed in the geriatrics compared to global studies. Most of the elderly population had moderate social health. Gender and education do not affect hypochondriasis and social health in the elderly. People with higher social health scores were clearly less likely to get hypochondriasis. Therefore, by improving the various dimensions of social health of the geriatrics, we can help reduce the prevalence of hypochondriasis in this age group.

Background: Patient management after bariatric surgery is important in controlling patients' diabetes and recurrence prevention. This study aimed to meet the medical managements of patients with diabetes 6 months after the bariatric surgery. Materials and Methods: This cross-sectional study was performed on 77 type 2 diabetes patients' candidates for bariatric surgery (Roux-en-Y [RYGP] and Omega). Postoperative implementation protocol was one-third of insulin for patients taking long-term insulin and the discontinuation of medications for patients of oral antidiabetic agents. Blood glucose (BG) level was checked regularly by the patients at home and the necessary medical management was applied. The weight, BG and HbA1C levels, and use of oral antidiabetic agents and insulin were assessed and recorded before 1, 3, and 6 months after the surgery. Results: BG levels and HbA1C percentage in the 1^st, 3^rd, and 6^th months after the intervention in Omega group were significantly lower than RYGB group (P value < 0.05). At 1 and 3 months after surgery, the mean insulin dose received by the Omega and RYGB groups was reduced to <30 units/day and 10 units/day, respectively, following the management protocol in this study. Moreover, 23.1% and 7.7% of patients in RYGB group and 12.1% and 3% of patients in Omega group took oral antidiabetic agents 1and 3 months after surgery, respectively. Insulin and oral antidiabetic agents were completely discontinued 6 months after the surgery. Conclusion: The long-term management and support of the patients by the implementation of a standard protocol after surgery are of great significance in obtaining the optimal outcome after bariatric surgery.

Background: The exact prevalence of hypertension in children surviving acute lymphoblastic leukemia (ALL) has not been fully estimated. The aim of this study was to investigate the prevalence of arterial hypertension (AH) and to determine the risk factors for the development of AH in children surviving ALL with current treatments. Materials and Methods: A total of 150 patients (84 males, 66 females, with an age range of 1–16 years) were included in the study. Demographic and clinical information of patients were initially recorded. Hypertension is defined as average systolic blood pressure (BP) and/or diastolic BP that is greater than the 95^th percentile for gender, age, and height. Results: The mean age at the assessment of BP was 11.3 and 9.8 years in the ALL and control group, respectively. A total of 20.6% of survivors of ALL and 10% of controls had high BP. Most patients in both groups had normal BP (65.3% patients in ALL group and 75.4% subjects in the control group). The number of patients with hypertension was significantly higher in ALL patients as compared with the control group (P = 0.026). Conclusion: The prevalence of AH in children surviving ALL is higher than in children in the general population, which emphasizes the need for regular monitoring of BP in children surviving ALL and intervention in the lifestyle of this population. Careful follow-up of BP status is warranted for long-term survivors of childhood cancer.

Background: The assessment of the emotional consequences of having a spinal deformity and orthotic management in people with idiopathic scoliosis is essential. This study was aimed to translate and culturally adapt the Bad Sobernheim Stress questionnaire (BSSQ-Brace) for Iranian adolescents with idiopathic scoliosis using thoracolumbar orthoses. Materials and Methods: The BSSQ was translated into Persian according to a standard guideline. The Persian BSSQ-Brace was completed by 55 Iranian subjects with spinal deformities who agreed to participate in this research. The validity was determined by correlating the Persian BSSQ-Brace questionnaire (BrQ) and the revised Scoliosis Research Society-22 patient questionnaire (SRS-22r). To assess test-retest reliability, all participants completed the BSSQ-Brace twice, with a gap of 1-week. Intraclass Correlation Coefficient and Cronbach's alpha were measured to report reliability. Results: All population revealed items in the Persian BSSQ-Brace were easily understood, and there was no difficulty completing them. The psychometric properties of the Persian version of BSSQ-Brace demonstrated excellent test-retest reliability (interclass correlation coefficient = 0.94), excellent internal consistency (Chronbach's alpha = 0.94), and high construct validity with SRS-22r (r = 0.74). Conclusions: The Persian BSSQ-Brace is a reliable and valid instrument to assess the emotional domains in subjects wearing a spinal orthosis.

Background: The current study aims to assess the effects of the large simple renal cyst (SRC) surgery on renal function for the first time. Materials and Methods: This case-series study included 22 patients with larger than 50 mm single SRC who underwent laparoscopic cyst unroofing surgery. Twenty-four-hour urinary protein, creatinine, and volume along with plasma creatinine and estimated glomerular filtration rate (GFR) were measured in patients before and 1 month after surgery. Patients underwent abdominopelvic computed tomography-scan without contrast and parenchymal thickness diameter adjacent to the cyst was measured before and after surgery. Results: Mean age and weight of patients were 52.2 ± 8.9 years and 77 ± 10.9 akg, respectively. There was no significant difference between plasma creatinine and GFR before and after surgery (P = 0.25 and 0.37, respectively). Twenty-four-hour urinary volume, creatinine, and protein before and after surgery revealed no significant changes (P = 0.37, 0.08, and 0.31, respectively). The mean improvement of parenchymal thickness diameter after surgery was 10.4 ± 0.7 mm which was statistically significant (P = 0.001). However, it was not correlated with the mean estimated GFR change (r = 0.349, P = 0.13). Conclusions: Although laparoscopic unroofing of renal cyst recovered renal parenchymal thickness noticeably, it did not improve renal function significantly; therefore, the latter factor lonely should not be considered a reason for surgery decision. Observation can be chosen as a safe treatment strategy in large SRCs without concern about renal function.

Background: Early and cost-effective diagnosis and monitoring of the infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are critically important to anticipate and control the disease. We aimed to set up a SYBR Green-based one-step real-time polymerase chain reaction (PCR) as a lower-cost alternative method to detect the virus. Materials and Methods: An in-house SYBR Green-based PCR assay targeting the envelope (E) and RNA-dependent RNA polymerase (RdRp) genes, was set up to diagnose the infection, and was compared with the reference probe-based PCR method. Results: When the commercial probe-based assay was considered as the reference method, SYBR Green-based PCR had a slightly lower sensitivity (81.98% and 86.25% for E and RdRp targets, respectively) and a good specificity (100% and 94.44% for E and RdRp targets, respectively). For both gene targets, three different melting temperature (Tm) patterns were found in the PCRs of the nasopharyngeal/oropharyngeal swab samples, but no size polymorphism was seen in agarose gel electrophoresis. Conclusion: Further studies to improvement of the assay are needed to make it an inexpensive and reliable tool for the diagnosis of COVID-19.

Background: The axillary reverse mapping (ARM) technique identifies and preserves arm nodes during sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND). Here, we aimed to investigate the prevalence of lymphedema following ARM. Materials and Methods: This is a clinical trial that was performed in 2019-2020 in Isfahan on patients with breast cancer in the early stages. Demographic and initial information of all cases including age and body mass index (BMI) was collected. Patients were then underwent SLNB ± ALND associated with ARM and were followed up for lymphedema every 6 months to a year. The occurrence of lymphedema was assessed. Results: By evaluating data of 102 patients, we found that 10 patients (9.8%) had lymphedema and patients with lymphedema had significantly higher age (P = 0.004), higher BMI (P = 0.001), larger tumor size (P = 0.018), and longer surgery duration (P < 0.001). The frequency of menopausal women was higher in patients with lymphedema compared to other cases (P = 0.001). Conclusion: The prevalence of lymphedema was high among patients undergoing ARM that was associated with factors including higher age, higher BMI, prolonged surgery duration, larger tumor size, and menopause. We believe that further comparative studies should be conducted on this issue.

Background: Knee osteoarthritis (KOA) may considerably change the gait parameters, including the gait variability patterns. Uncontrolled manifold (UCM) analysis has been used to evaluate the relationship between motor control and gait variability as a useful index for assessing the multi-segmental movements' coordination during walking. To our knowledge, no research has evaluated the alterations in the gait kinematic parameters during normal and narrow path walking in individuals with KOA as compared to asymptomatic people. Materials and Methods: In this cross-sectional study, individuals diagnosed with mild to moderate medial KOA and asymptomatic people will walk at their comfortable preferred speed on a treadmill. A motion capture system will be used to record at least 50 successful gait cycles. The kinematic variability of joints during gait will be analyzed using UCM, with the center of mass (COM) displacement considered as the performance variable. The primary outcome measure will be the lower limb synergy index. Variability of the COM displacement and changes in angles and angular velocities of lower extremity joints will be assessed as the secondary outcomes. Results: The results of this protocol study provide information on the lower limb kinematic synergy during gait on normal and narrow paths for individuals with KOA and asymptomatic controls. Conclusion: This information will help the researchers and clinicians understand KOA patients' gait variability characteristics more deeply. Moreover, it may lead to an enhanced evidence-based approach for clinical decision-making concerning improving gait stability and decreasing the falling risk in these people.

Background: Severe varus deformity of the knee poses a technical challenge in balancing the flexion–extension gaps. The use of a varus–valgus constrained prosthesis is a solution to achieve coronal plane stability. The results of constrained condylar knee (CCK) implants in primary total knee arthroplasty are not well known. This study aims to compare the functional outcomes of posterior-stabilized (PS) and CCK implants for primary arthroplasty of the varus knee. Materials and Methods: Twenty patients with bilateral severe osteoarthritis and genu varum of more than 10° were enrolled in this study. One knee was randomly implanted with a fixed-bearing PS implant, whereas the other was implanted with a CCK prosthesis. Pre- and postoperative Knee Society Score (KSS) and Oxford Knee Score (OKS) questionnaires were completed, and knee flexion was measured and compared. Results: The patients were followed for 32 months on average (24–36 months). On the KSS and OKS, both the groups improved significantly, but the difference between them was not statistically significant. Postoperative knee flexion was also not different between the two groups. Furthermore, 18 patients could not distinguish the difference between the two prostheses, whereas two patients preferred the PS one. Conclusion: We demonstrated that a PS prosthesis can achieve comparable functional results to the CCK one in the short term.

Background: Carvacrol is a natural phenolic monoterpene with anti-inflammatory and antioxidant bioactivities. Neuroinflammatory and oxidative stress responses play a crucial role in the pathogenesis of Alzheimer's disease. The present study examined the effect of carvacrol on brain tumor necrosis factor-alpha (TNF-α) level and oxidative stress as well as spatial learning and memory performances in lipopolysaccharide (LPS)-exposed rats. Materials and Methods: The rats were treated with either carvacrol (25 and 50 mg/kg) or Tween 80 for 2 weeks. Thereafter, LPS (1 mg/kg) or saline was intraperitoneally administered on days 15–19, 2 h before Morris water maze task, and treatments with carvacrol or Tween 80 were performed 30 min prior to behavioral testing. The level of TNF-α, lipid peroxidation, and total thiol concentration were measured in the hippocampus and cerebral cortex at the end of the experiment. Results: It was found that LPS-exposed rats exhibited spatial learning and memory dysfunction, which was accompanied by increased TNF-α level and lipid peroxidation, and decreased total thiol concentration in the hippocampus and/or cortex. Moreover, treatment with carvacrol at a dose of 25 mg/kg attenuated learning and memory impairments, decreased TNF-α and lipid peroxidation level in the hippocampus and cortex, and increased total thiol concentration in the cortex. Conclusion: Carvacrol exerts neuroprotective effects against LPS-induced spatial memory deficits through attenuating hippocampal TNF-α level and oxidative stress in rats.

Also known as intravascular papillary endothelial hyperplasia, Masson's tumor is a relatively rare soft-tissue vascular tumor that usually arises in the hand. Felon is an abscess formation in the distal phalanx that usually occurs following a penetrating microtrauma. We present a 30-year-old patient who was referred to our clinic with a palpable mass in the distal phalanx of the index finger after a needle stick injury. At first, the lesion was treated as a felon but finally and after treatment failure, a complete reevaluation revealed the lesion to be a Masson's tumor of the distal phalanx.

Ataxia–telangiectasia (AT) is a type of primary immunodeficiency characterized by an autosomal recessive mode of inheritance and usually presents with progressive cerebellar ataxia in early life. This complex disease is associated with humoral and cellular immune dysfunction and other features including characteristic oculocutaneous telangiectasia and increased predisposition to cancers, particularly lymphoma and leukemia. An 11-year-old Iranian girl presented with primary immunodeficiency and was diagnosed as having AT according to her clinical manifestations and molecular findings. She had a history of two types of non-Hodgkin's lymphoma and showed spontaneous regression of her diffuse large B-cell lymphoma without any specific treatment. Gene mutations and dysfunction in patients with AT result in different manifestations including abnormal development of the thymus, immunodeficiency, increased susceptibility to malignancies, and increased radiosensitivity. No standard treatment is available for these patients. The use of immunotherapeutic strategies in patients with primary immune deficiency disease-associated tumors is potentially important.

Background: One of the basic practices in the field of waste management is the collection and treatment of leachate. Leachate from municipal waste due to high chemical oxygen demand (COD) and dark color is a potential pollutant of the environment, which causes a lot of problems in the absence of treatment and direct discharge to the environment. This study aimed to determine the efficiency of ultrasonic process in combination with coagulation and flocculation process using sodium ferrate in COD and color reduction. Materials and Methods: In this experimental study, all experiments were performed in batch conditions and with changing process variables such as pH and sonication time, and the effect of three parameters, including ultrasonic reaction time (15, 30, and 45 min), pH (2, 4, 5/5, and 7), and coagulant dosage (from 1 to 150 g/l) on the COD reduction and color removal, was evaluated. Coagulant concentration and then the removal efficiency of COD and color were analyzed by ANOVA using SPSS 18. Results: The COD reduction and color removal were 87.05% and 88.6% in optimal condition (using 120 g/L of sodium ferrate at pH 5.5), with coagulation/flocculation, after ultrasound (15 min). Ultrasound (15 min) + sodium ferrate (without coagulation/flocculation) achieved 46.25% of COD reduction and 90.35% of color elimination, whereas the ultrasonic process alone allowed removing the COD and color in the leachate by less than 50%. Conclusion: The results indicate that C–F followed by ultrasonic can be used to efficiently reduce the organic matter and color from municipal waste leachate, and it would be an ideal option for leachate treatment.

Background: Oral candidiasis (OC) has been noticed as a common mucous membrane infection in immunocompromised patients such as that diabetes. This study, focused on the genotyping of Candida albicans and enzymatic activities of Candida species recovered from oral mucosa among diabetes patients and healthy individuals. Materials and Methods: Specimens were obtained from oral mucosa of One-hundred and sixty patients with type 2 diabetic and 108 healthy individuals. All isolates were definitely identified by ribosomal DNA (rDNA) gene sequencinghHydrophobicity, hemolytic activities of Candida species and genotypes of C. albicans were determined through polymerase chain reaction (CA-INT). Results:, Eighty eight (55%) samples out of 160, were positive for Candida species in diabetic patients. Moreover, 79.5% (70/88) and 20.5% (18/88) isolates belonged to the C. albicans and non-albicans Candida species respectively. Three genotypes of C. albicans have recovered in diabetic patients: genotype A (71.42%), B (21.42%), and C (7.14%). In healthy individuals, 42.6% (46/102) Candida species recovered from oral cavity, with the highest prevalence of genotype A (76.6% of C. albicans). Additionally, hydrophobicity and hemolytic activities from Candida species were significantly greater in diabetes patients than healthy nondiabetic subjects. Conclusion: Collectively, C. albicans was the most causative agent isolated from diabetes patients and non-diabetes healthy individuals. Genotype A, as the most remarkable genotype, should be mentioned in both groups. Higher potential hydrophobicity and hemolytic activities of Candida species in diabetic patients compared to healthy cases suggest these features triggering pathogenicity of OC in diabetes patients.

Background: The aim of this study was to compare the effect of adding oral clonidine to standard treatments on pain intensity in patients with acute renal colic. Materials and Methods: This is a randomized clinical trial that was performed in 2020 in Isfahan. The study population consisted of 200 patients with renal colic. Pain of the patients was assessed using Visual Analog Scale. Patients were then randomized into 4 groups of 50 patients. Group A received 0.1 mg/kg morphine and clonidine tablets (0.2 mg). Group B received morphine and placebo. Group C received 30 mg ketorolac and clonidine tablets. Group D received 30 mg ketorolac and placebo tablets. Pain of patients was assessed. 0.05 mg/kg morphine was administered and repeated every 40 min if the pain was not reduced. Results: Our data showed that there was a significant difference between pains of patient by the time of admission in groups (P = 0.04). However, no significant differences were observed between pains of patients in different measuring times (P > 0.05). Using general linear model, we showed that the decreases in pain scores of each group were significant (P < 0.05) but there were no significant differences in pains of patients in different measuring times (P > 0.05). Our data showed that Group A and Group C had lowest frequencies of morphine administrations while Groups B and D had the highest frequencies (P < 0.001). Conclusion: We showed that administration of clonidine in patients with renal colic resulted in better pain control and lower morphine injections.

Background: Ectopic pregnancy (EP) occurs in 1% of pregnancies, and may seriously effects on women's health and future fertility so this study aimed to compare the results of hysterosalpingography (HSG) after treatment of EP by laparoscopy, laparotomy, and methotrexate (MTX) therapy. Materials and Methods: This was a clinical trial study was done on 112 EP women with treatment indication referred to Isfahan Al-Zahran and Shahid Beheshti Hospitals from 2017 to 2018. They were divided into 33 populated groups of laparoscopic salpingostomy, laparotomy and MTX. Then patients of three groups underwent HSG 3 months after intervention. The factors such beta human chorionic gonadotropin (β–hCG) (mIU/mL), size of EP (mm), infection, hospital length of stay (LOS), and tubal patency were recorded and compared between the groups. Results: There were no significant differences between groups for age, body mass index, β–hCG, Size of EP, and hospital LOS (P > 0.05). The infection was more frequent in laparotomy group with no significant difference among three groups. The infection rates were 9%, 12%, and 6% for MTX, laparotomy, and laparoscopy arms, respectively. Between the three groups tubal patency as primary outcome had higher frequency than laparoscopy group, although, the difference was not statistically significant (P = 0.595). Conclusion: Although infection was more in laparotomy and that tubal patency was more within 3 months in laparoscopy and MTX, there were no statistically significant differences in the results of laparoscopy, laparotomy, and MTX in HSG results.

Background: CA1, as a major structure involved in learning and memory, has been shown to be affected by tramadol addiction. Both orexin and endocannabinoid receptors express in CA1 and play an important role in drug dependency. The aim of this study was to evaluate the modulatory effects of orexin-2 (OX2R) and endocannabinoid-1 (CB1R) receptors on neuronal activity in CA1, in response to tramadol in rats. Materials and Methods: Male Wistar rats were divided into 8 groups (n = 6–7); saline-dimethyl sulfoxide (DMSO), tramadol-DMSO, saline-TCS-OX2-29, saline-AM251, tramadol-TCS-OX2-29, tramadol-AM251, saline-TCS-OX2-29-AM251, tramadol-TCS-OX2-29-AM251. Tramadol was injected intraperitoneally, and then, AM251 (1 nmol/0.3 μL), CB1R antagonist and TCS-OX2-29 (1 nmol/0.3 μL), OX2R antagonist, were microinjected individually or concurrently into the CA1. Using in vivo extracellular single-unit recording, the firing of CA1 pyramidal neurons was investigated. Results: Tramadol decreased neuronal activity in CA1 (P < 0.01) but increased it after micro-injection of DMSO. TCS-OX2-29 increased neuronal activity in saline group (P < 0.05) but decreased it in tramadol group. AM251 had no effect on saline group but decreased neuronal activity in tramadol group (P < 0.05). Concurrent micro-injection of TCS-OX2-29 and AM251 had no effect on saline group but decreased neuronal activity in tramadol group (P < 0.05). Conclusions: Our findings suggest that neural activity in CA1 is rapidly affected by acute use of tramadol, and some of these effects may be induced through the endocannabinoid and orexin systems. Thus, the function of endocannabinoid and orexin systems in CA1 may play a role in tramadol addiction.

Background: The present study investigated the plasma level of fibrinogen before and after removing the pump in coronary artery bypass graft (CABG) surgery and its relationship with the need for blood products. Materials and Methods: The present study was performed on 60 patients who were candidates for CABG surgery. The fibrinogen level of these patients was assessed and recorded before surgery and immediately after removing the pump. In addition, their hemoglobin level was recorded before the operation and 2 h after. In addition, the number and type of blood products transfusion were recorded intraoperatively and postoperatively and also at the intensive care unit. Results: Patients' fibrinogen level after removing the pump with the mean of 130.53 ± 122.01 mg/dl decreased significantly compared to before surgery with the mean of mg/dl 224.95 ± 132.88 mg/dl (P < 0.001). In addition, the prognostic value of fibrinogen after removing the pump in determining the postoperative need of blood transfusion showed that the cut-off value of fibrinogen was < 196 mg/dl with a sensitivity of 16.82% and specificity of 80%, but it was not statistically significant (area under the curve [95% confidence interval]: 0.519 [0.350–0.689]; P = 0.825). Conclusion: According to the results of the present study, due to significant changes in fibrinogen levels after removing the pump compared to preoperation, it seems that this factor can play an important role in prognosis of the need to postoperative blood transfusion, although the prognostic value and the critical point mentioned in our study was not significant and it is required to do further studies.

Background: Tramadol is an opioid analgesic with monoamine reuptake inhibitory effects. Although tramadol has been widely used to control pain, there is controversy about the risk of abuse. Therefore, in the present study, the acute effects of tramadol on neuronal activity in the medial prefrontal cortex (mPFC), which is one of the important centers of the reward system, were investigated electrophysiologically. Materials and Methods: Tramadol was injected interperitoneally (12.5 and 25 mk/kg) or subcutaneously (40 mg/kg) and its effect on the firing of mPFC neurons was investigated, using in vivo extracellular single unit recording. Results: Tramadol could not significantly affect neural activity in mPFC, suggesting no acute and rapid effect on mPFC. Conclusions: The present results showed that neural activity in mPFC was not rapidly affected by acute application of tramadol. Since the role of mPFC in tramadol addiction has been elucidated, it can be concluded that these effects may be due to delayed responses or chronic use of tramadol.

Introduction: The aim of this study was to assess the effect of a community-based intervention on social capital, quality of life, self-care, and health literacy among elderly. Materials and Methods: This quasi-experimental trial was conducted at two health-care centers in Isfahan, Iran, which assigned to the intervention and control groups. A total of 86 elderly (60 years or above) enrolled in the study. The intervention program consisted of 12 weekly group sessions with various health topics. Nine sessions held in the health-care center and three local tours in different locations of the neighborhood. The control group received routine care of health centers. Social capital, quality of life, self-care, and health literacy were assessed at baseline and 1 month after the intervention in two groups. Results: Mental component of quality of life (P = 0.026), self-care, and health literacy (P < 0.001) showed a significant increase in the intervention group compared to the control group at 1 month after the intervention. The total score of social capital and the dimensions of local community participation, social agency, feelings of security and trust, interactions with neighbors, and interactions with family and friends improved in the intervention group (P < 0.001). However, there was no significant difference in the dimensions of tolerance of diversity (P = 0.241) and value of life (P = 0.928). Conclusions: This community-based interventions with a variety of diverse and participatory components can be used as a strategy to promote the health of the elderly in primary health care.

Background: Altered heart rate variability (HRV) has been associated with a number of disorders affecting autonomic tone, including recent myocardial infarction, congestive heart failure, and diabetic neuropathy. Furthermore, obstructive sleep apnea (OSA) has been shown to be associated with characteristic disturbances in heart rhythm. In this study, using HRV frequency analysis, an attempt has been made to diagnose or possibly diagnose OSA. Materials and Methods: Using Somnologica version 3.3.1 software (Medcare-Embla), polysomnographic recordings were done. Electrocardiographic signals were digitalized with a sampling rate of 250 Hz. Using the HRV analysis report of this software, low-frequency (LF) and high- frequency (HF) information and LF to HF ratio (LF/HF) were obtained at 5-min intervals, then at cutting points 30, 35, 40, 45, and 50, which indicate the intensity of the apnea and hypopnea index (AHI), were analyzed with mean and standard deviation of HRV frequencies. Results: According to the results reported in this study, comparison of mild, moderate, and severe cases led to no significant differences, while frequency-domain analysis displayed significant LF/HF increase in more severe AHI cases. This can probably be applied in screening high-risk patients, reducing the application of PSG in high probable cases, and providing an estimate of prognosis of potentials patients for the physicians. Conclusions: In the study of frequency-domain analysis, LF/HF increases in more severe AHI cases. These can probably be applied in screening high-risk patients, reducing the application of PSG in high probable cases.

Background: Spatial disease mapping is a widespread tool in ecological analysis to obtain accurate estimates for incidence, relative risks (RRs), prevalence, or mortality rates regarding to increase the incidence of gastrointestinal (GI) cancer in Isfahan in recent years. This study aimed to inspect the RR of GI cancer in Isfahan counties using empirical and full Bayesian model. Materials and Methods: Data of this ecological study were GI cancer cases which registered in health-care system of Isfahan University of Sciences during 2005–2010. We applied shared component model to model the spatial variation incidence rates of the GI cancers. We compared three models such as Gamma–Poisson, lognormal, and Besag, York, and Mollie (BYM) Bayesian. WinBUGS and GIS 10.1 software were used. Results: According to the fitted model, BYM model had best fit to the data. However, in general, ranks of RRs in most counties are identical; counties with higher RR in one map have higher RR in other maps. Geographical maps for three cancers in women were smoother than men. Isfahan has high RR in women, whereas this point is slightly different in men. Daran, FreidoonShahr, and Isfahan are cities which have high RR in esophagus, stomach, and colon cancer, respectively. Conclusions: Lognormal and BYM maps had very similar results. Despite some differences in estimation values, in nearly all maps arias Isfahan had high RR in GI cancer. It is recommended to promote the use of screening programs and increase awareness of people in high RR areas to reduce the incidence of GI cancer.

Background: The present study aims to evaluate the diagnostic exactitude of the intraoperative Chertsey test in tibiofibular syndesmotic injuries in patients with malleolar fractures, in comparison with a computed tomography (CT) scan. Materials and Methods: In this study, patients with malleolar fractures operated between 2018 and 2020 were examined. Thirty-nine patients were enrolled in the study. A three-dimensional preoperative CT scan was obtained. The opposite unfractured ankle was also scanned and considered as the control group. The Chertsey test was performed during the operation to assess the syndesmosis injury. Then, patients were partitioned into two distinct groups, considering the condition of their ankle, namely the Chertsey positive (unstable syndesmosis) group and the Chertsey negative (stable syndesmosis) group. Results: The outcomes of the present survey illustrated that the Chertsey test was positive in 16 patients (41.03%) and negative in 23 patients (59.07%). The median of all CT scan parameters (anterior tibiofibular distances (TFD), middle TFD, posterior TFD, and maximal TFD and volume) before surgery in the group of patients with a positive Chertsey test was significantly higher, measured against the unfractured control group (P < 0.001 for all parameters). Furthermore, a comparison of CT scan parameters and syndesmosis space volume before surgery between the two groups of patients with positive and negative Chertsey test results showed that the measurement of parameters in Chertsey-positive patients was significantly higher than the Chertsey-negative patients (P < 0.001). Conclusion: Chertsey test could be used to diagnose syndesmosis injuries in patients with malleolar fractures due to its high importance in the outcome of patients.

Background: Insulin-like growth factor binding protein-3 receptor (IGFBP-3R) (Transmembrane protein 219 [TMEM219]) binds explicitly to IGFBP-3 and exerts its apoptotic and autophagy signalling pathway. Constructing a Henrietta Lacks (HeLa) h6-TMEM219 cell characterize the therapeutic potent of TMEM219 that could interrupt the IGFBP-3/TMEM219 pathway, in cancer treatment and destructive cell illnesses such as diabetes and Alzheimer's. Materials and Methods: First, to develop stable overexpressed HeLa h6-TMEM219 cells, and Escherichia coli BL21 (DE3) with high IGFBP-3R expression, the purchased pcDNA3.1-h6-TMEM219 plasmid was transformed and integrated using CaCl2 and chemical transfection reagents, respectively. The pcDNA3.1-h6-TMEM219 transfection and protein expression was evaluated by the polymerase chain reaction (PCR), western blotting, and flow cytometry. Following the induction of h6-TMEM219 expression, a protein was purified using Ni-NTA chromatography and evaluated by the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Results: The 606 base pairs sequence in PCR outcomes confirmed successful pcDNA3.1-h6-TMEM219 transformation in E. coli BL21 and integration into the HeLa genome. The analysis of protein samples from induced E. coli BL21 and purified protein demonstrate a band of approximately 22 kDa on SDS-PAGE. Moreover, besides western blot analysis, flow cytometry findings illustrate approximately 84% of transfected HeLa cells (HeLa h6-TMEM219) overexpressed h6-TMEM219 on their surface. Conclusion: We designed a new experiment in the h6-TMEM219 expression procedure in both eukaryotic and prokaryotic hosts. All of our results confirm appropriate transformation and transfection and importantly, approve h6-TMEM 219 membrane expression. Finally, the HeLa h6-TMEM219 cells and the newly purified h6-TMEM219 leverage new studies for molecular diagnostic studies and characterize the therapeutic agents against IGFBP-3/TMEM219 signalling pathway in devastating illnesses in vitro and in vivo.

Background: CA125 is the most used tumor marker for ovarian cancer monitoring and diagnosis. This study aimed to evaluate the capacity to predict malignancy in women with adnexal tumors using CA125 measurement and ultrasound criteria before the pathological examination. Materials and Methods: This observational diagnostic study was conducted on 300 patients with obvious diagnosis of adnexal mass consists of ovarian masses, fallopian tubes, and masses within the broad ligament referring to Alzahra and Beheshti Hospitals from 2018 to 2019. Ultrasound examinations were done before surgery and malignancy risk was investigated by the ADNEX criterion. Sensitivity, specificity, positive and negative likelihood ratio (likelihood ratio [LR]+ and LR−), and area under the curve (AUC) were calculated. Results: From 284 patients, 260 masses were categorized in benign, 18 were in borderline, and 18 masses were malignant. The mean age of patients with malignant tumors was significantly higher than the others (P = 0.01). Differences in the level of CA-125 were not statistically significant (P = 0.78). Furthermore, the proportion of ascites in the malignant group (16.3%) was significantly higher than the others (P = 0.003). The AUC in ADNEX model (cutoff ≥9%) for differentiation of benign and malignant tumors was 0.75 (95% confidence interval [CI]: 0.69–0.80) with a sensitivity of 0.63 (95% CI: 0.41–0.81) and a specificity of 0.80 (95% CI: 0.74–0.84). Receiver operating characteristic analysis for CA-125 revealed that this variable is not capable for discrimination between benign and malignant tumors as the AUCs of the aforementioned variable were 0.60, 0.60, and 0.52 for the whole patients, premenopause, and postmenopause categories. Conclusion: CA-125 marker, along with other ultrasound findings, can be more accurate in identifying the malignancy of the adnexa tumor.

Background: Tenascin-C (TNC) is a large glycoprotein of the extracellular matrix which associated with poor clinical outcomes in several malignancies. TNC over-expression is repeatedly observed in several cancer tissues and promotes several processes in tumor progression. Until quite recently, more needs to be known about the potential mechanisms of TNC as a key player in cancer progression and metastasis. Materials and Methods: In the present study, we performed a bioinformatics analysis of breast and colorectal cancer expression microarray data to survey TNC role and function with holistic view. Gene expression profiles were analyzed to identify differentially expressed genes (DEGs) between normal samples and cancer biopsy samples. The protein-protein interaction (PPI) networks of the DEGs with CluePedia plugin of Cytoscape software were constructed. Furthermore, after PPI network construction, gene-regulatory networks analysis was performed to predict long noncoding RNAs and microRNAs associated with TNC and cluster analysis was performed. Using the Clue gene ontology (GO) plugin of Cytoscape software, the GO and pathway enrichment analysis were performed. Results: PPI and DEGs-miRNA-lncRNA regulatory networks showed TNC is a significant node in a huge network, and one of the main gene with high centrality parameters. Furthermore, from the regulatory level perspective, TNC could be significantly impressed by miR-335-5p. GO analysis results showed that TNC was significantly enriched in cancer-related biological processes. Conclusions: It is important to identify the TNC underlying molecular mechanisms in cancer progression, which may be clinically useful for tumor-targeting strategies. Bioinformatics analysis provides an insight into the significant roles that TNC plays in cancer progression scenarios.

The emerging of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak is associated with high morbidity and mortality rates globally. One of the most prominent characteristics of coronavirus disease-19 (COVID-19) is lymphopenia, which is in contrast to other viral infections. This controversy might be explained by the evaluation of impaired innate and adaptive immune responses, during the SARS-CoV-2 infection. During the innate immune response, poly-ADP-ribose polymerase hyperactivated due to virus entry and extensive DNA damage sequentially, leading to nicotinamide adenine dinucleotide (NAD)+ depletion, adenosine triphosphate depletion, and finally cell death. In contrast to the immune response against viral infections, cytotoxic T lymphocytes decline sharply in SARS-CoV-2 infection which might be due to infiltration and trapping in the lower respiratory tract. In addition, there are more factors proposed to involve in lymphopenia in COVID-19 infection such as the role of CD38, which functions as NADase and intensifies NAD depletion, which in turn affects NAD+–dependent Sirtuin proteins, as the regulators of cell death and viability. Lung tissue sequestration following cytokine storm supposed to be another reason for lymphopenia in COVID-19 patients. Protein 7a, as one of the virus-encoded proteins, induces apoptosis in various organ-derived cell lines. These mechanisms proposed to induce lymphopenia, although there are still more studies needed to clarify the underlying mechanisms for lymphopenia in COVID-19 patients.

Background: Mortality due to acute coronary syndrome (ACS) has dramatically diminished because of performing life-saving interventions. This study aims to assess the metabolic risk factors and heart healthy lifestyle following the first episode of ACS under percutaneous coronary intervention (PCI) treatment after the 6-month follow-up. Materials and Methods: This is a longitudinal study conducted on 40 patients who underwent PCI because of the first episode of ACS. The patients' information including age, weight, abdominal circumference, smoking, functional capacity, patients' metabolic equivalent of task (METS), and laboratory tests including triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), creatinine, fasting blood sugar (FBS), and hemoglobin A1C were recorded before discharge and reassessed after 6-month follow-up. Results: The patients were dominantly male (92.5%) with an average age of 56.8 ± 7.11 years. Physical activity and functional capacity (METS) significantly improved within 6 months (P = 0.019). BMI significantly improved; however, although the abdominal circumference decreased, it was not significant (P = 0.28). The number of smokers (P = 0.12) and the daily number of smoked cigarettes (P = 0.37) nonsignificantly decreased within 6 months. However, HDL-C (P = 0.013) and LDL-C (P = 0.027) changes were not desirable. TG, FBS, and blood pressure did not statistically significant change (P > 0.05). Conclusion: Although BMI, physical activity, and METS remarkably improved, waist circumference decreased nonsignificantly and lipid profile got worse paradoxically. Although this population is limited for generalization, this study shows that we require further schedules to improve ACS secondary prevention practice in our community.

Background: Thyroid hormones are essential to maintain the tissue's metabolism throughout the life. Thyroid hormones exert their effects on physiology and almost all body functions. Carrot is a rich source of iodine and carotenoids that can interfere in the synthesis of thyroid hormones. Materials and Methods: The present study was designed to investigate the effects of carrot consumption on T4 levels and its effect on memory, nerve conduction velocity (NCV), animal weight, and finally, on water and food intake in Wistar rats. In this study, 24 male rats were used and divided into three groups: Control, Ca 200 mg/kg, and Ca 400 mg/kg. Results: The results indicated that carrot consumption at Ca 200 mg/kg treated group increased the level of serum T4 and induced hyperthyroidism. Animal weight in both treated groups did not change compared to the control group (P > 0.05). Water and food consumption, and the level of T4 in Ca 200 mg/kg group increased when compared to the control group (P < 0.05). NCV in both treated groups was not significantly different in comparison with the control group (P > 0.05). Spatial memory and passive avoidance memory in both treated groups significantly decreased compared to the control group (P < 0.05). Conclusion: Carrot consumption, via increases the synthesis of thyroid hormones, creates hyperthyroidism, but due to induced moderate hyperthyroidism did not impact on weight. Moderate hyperthyroidism induced appetite and memory impairment. Then increased food intake or effect of hyperthyroidism on metabolism increased water intake.

Background: Sacroiliac pain is one of the causes of low back pain, representing with discomfort and tenderness in the sacroiliac joint. Interventional procedures might be beneficial in cases unresponsive to medical treatments. Here, we aimed to investigate the effects of intra-articular corticosteroid injections in patients with sacroiliac pain. Materials and Methods: This is a clinical trial performed in 2017–2018 in Kashani Hospital, Isfahan, on patients with low back pain and formerly diagnosed with sacroiliac pain. Patients were recruited based on inclusion and exclusion criteria. Corticosteroid injections were performed for patients. Patients were visited within 2 weeks, 4 weeks, and 6 months after interventions, and pain and disabilities of patients were assessed using the numerical rating scale (NRS) and Oswestry Disability Questionnaire. Results: A total number of 27 patients entered our clinical trial. We showed that the mean NRS score among patients before interventions was 8.01 ± 0.96. Assessments of disability score also indicated that the mean disability scores was 41.48 ± 7.48. Our data also indicated that there was a significant reducing trend in both NRS and disability score after interventions (P < 0.001 for both items). Conclusion: Intra-articular steroid injection is associated with significantly reduced pain and disability in patients with sacroiliac pain. Previous studies evaluated variable methods and reported that this method has high values and significant advantages compared with other techniques which were in line with our results.

Background: The aim of this study was determination of the effect of the transversus abdominis plane block (TAP block) with ropivacaine 0.5% in relieving postoperative pain after laparoscopic gynecologic surgery. Materials and Methods: The population of the double-blinded clinical trial study included 200 women candidates for elective laparoscopic gynecologic surgery who referred to Al-Zahra and Beheshti hospitals in Isfahan during 2016–2018. In the TAP block group in addition to standard general anesthesia, an anesthetic drug Ropivacaine (Naropin, 0.5%) was injected at a dose of 0.5 mg/kg between transverse abdominal muscle and internal oblique muscle facia. And in control group just received standard general anesthesia. Hence, the severity of pain and nausea and vomiting is recorded at the time of recovery, at 30 min, 2, 4, 6, 12, and 48 h after the surgery. Results: The results of this study showed that in all periods of time (30 min, 2, 4, 6, 12, 24, 36, and 48 h after the surgery), mean pain score in TAP block group was lower than control group (P < 0.001). Hence that, in the 48 h after the surgery, the pain score in the TAP block group with a mean of 0.46 ± 0.50 was significantly lower than the control group with a mean of 1.06 ± 0.68 (P < 0.001). Nausea and vomiting between the two groups were no significant differences. There was no decrease in narcotic use or length of stay among those who received the TAP block. Conclusions: TAP block with ropivacaine 0.5% had a significant role in reducing postoperative pain of laparoscopic surgery.

Background: This study aimed to compare the efficacies of four anesthetic induction drugs (thiopental, propofol, midazolam-thiopental, and etomidate-propofol) on cardiovascular response during laryngeal mask airway (LMA) placement in eye surgery. Materials and Methods: The present clinical trial study included 128 patients who were candidates for ophthalmic surgery in four groups. Patients in the first group were given a combination of midazolam (0.04 mg/kg) with thiopental (2.5 mg/kg) (Group T + M). We administered propofol alone (2.5 mg/kg) to patients in the second group (Group P). The third group received a combination of etomidate (0.1 mg/kg) with propofol (1 mg/kg) (ET + P group) and patients in the fourth group received thiopental drug (5 mg/kg) alone (Group T). Then, the stability of patients' hemodynamic parameters before anesthesia was evaluated and compared immediately after anesthesia, 1, 3, and 5 min after LMA placement. Results: There was no significant difference between the four groups in changes in oxygen saturation level (P > 0.05). Furthermore, the difference between decreased systolic blood pressure and diastolic blood pressure over time was not significant in 5 min in both Groups T + M and T (P > 0.05). In addition, the stability of these two groups was higher than the other two groups (P < 0.05) and the most unstable group was Group P. The changes pulse rate in the P group were significant (P < 0.05). Conclusion: According to the results of the current study, thiopental and Midazolam can be used as an effective induction compound to facilitate LMA insertion with higher hemodynamic stability compared to propofol alone, propofol and etomidate, and thiopental alone.

Background: This research intended to investigate the characteristics of COVID-19, accurately evaluate radiological findings, and compare it with laboratory evidence of coronavirus. Materials and Methods: A retrospective study of 120 consecutive cases with a mean age of 55.9 ± 15.82 years and laboratory-confirmed COVID-19 pneumonia was performed. On admission, C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) levels were tested. Computed tomography (CT) findings and scored pulmonary involvement were evaluated. Results: An elevated level of CRP and mildly raised ESR was seen in all patients. ESR showed a meaningful difference between both genders (P < 0.05). Ninety-four (78.3%) patients showed peripheral pulmonary lesions and 119 patients had ground-glass opacity (99.2%), 110 (92.4%) had consolidation, and 9 patients (7.5%) had linear opacities. Of 120 cases, 25 (20%) had bronchial changes, 25 (20%) had air bronchogram, 11 (9.2%) had bronchial distortion, and 2 had mediastinal lymphadenopathy. The CT scores in males and females were 17.41 ± 4.86 and 14.65 ± 4.96, respectively with a significant difference between both genders (P = 0.001). CT score difference was significant between both genders (P = 0.01). The largest lung lesion diameter in both sexes (male: 46.0725.75 and female: 57.9131.14) showed a meaningful difference. CRP (r = 0.10; P < 0.05) and ESR (r = 0.15; P < 0.05) were correlated with the CT scores. Conclusion: the results indicated that the infection involved lung parenchyma and interstitium. CRP and ESR levels were correlated with lung lesions and showed positive performance in predicting severity and disease monitoring.

Diagnosing breast cancer (BC) in early stages increases the chances of treating this cancer in men. However, because BC is very rare in men, especially inflammatory BC (IBC), it is unlikely that screening men for BC by mammography or other tests would yield promising outcomes. The aim of this study was to report IBC in a 53-year-old man. The case was a 53-year-old man with a history of mass in the left breast and trauma to the same side as well as swelling and severe redness of the breast skin. The patient underwent neoadjuvant chemotherapy and relative responded to medical treatment. He then underwent modified mastectomy surgery and initial chest wall repair followed by radiotherapy. IBC in men is challenging due to its rarity, unknown biological behaviors, and difficulty in early diagnosis. This tumor is usually detected in advanced stages in the elderly and has a poor prognosis.

Background: In the present study, the effects of intra-basolateral amygdala (BLA) blockade of dopamine D1 receptor on morphine-induced conditioned place preference (CPP) were investigated in male Wistar rats. Materials and Methods: A 5-day CPP paradigm was used. Morphine was injected subsequently at effective (5 mg/kg) and ineffective (0.5 mg/kg) doses. SCH 23390 (0.5– μg/rat), as a selective D1 receptor antagonist, was microinjected bilaterally into the BLA. Results: Effective dose of morphine induced a significant CPP, and increased the locomotor activity during the testing phase. The results showed that morphine-induced CPP was significantly suppressed by D1 receptors antagonist in BLA in the acquisition phase and caused an aversion even at high doses. The antagonist also significantly prevented CPP expression. Morphine increased the motor activity, but the D1 receptors blockade, significantly reduced it. Conclusions: The findings of this study suggest a possible role for BLA dopamine D1 receptors in reward responses in morphine dependency.

Parsonage-Turner syndrome (PTS) is a rare syndrome of unknown etiology; however, it is believed that an abnormality of immune response after a previous infection may be the cause of the disease. We report neuralgic amyotrophy in a patient with a history of kidney transplantation with severe acute respiratory distress syndrome coronavirus 2 infection. This literature is reviewed regarding clinical presentation, etiology, treatment, and prognosis of PTS after COVID-19 infection. We should consider PTS as another complication of COVID-19 infection.

Background: One of the most common problems in the intensive care units (ICUs) is pressure ulcers (PUs). The present study aimed to evaluate the effectiveness of aloe vera gel, olive oil, and compound aloe vera gel-olive oil in the prevention of PUs. Materials and Methods: This randomized clinical trial was conducted on 240 patients. They were randomly divided into four groups, aloe vera gel (n = 60), olive oil (n = 60), aloe vera gel-olive oil combination (n = 60), and control (n = 60). Braden scale and National Pressure Ulcer Advisory Panel scale were used to collect data. The intervention was performed for 30 days. In the intervention and control groups, the patient received routine care. In each intervention group, 10–15 ml of olive oil or aloe vera gel or a combination of olive oil and aloe vera was rubbed into body areas under pressure. Results: There were no PUs detected in all groups before the intervention; after the intervention, 12 patients in the olive group, 20 patients in the aloe vera group, 10 patients in the aloe vera-olive combination group, and 22 patients in the control group developed PUs. The results reported 40% of the patients with stage 1 PU and 10% of them with stage 2. Conclusion: Due to the effectiveness of olive oil and aloe vera-olive oil combination in preventing PU, it is recommended to use these herbal compounds in preventing PU on ICU patients.

Schwannoma is a rare tumor in the colon which originates from the peripheral nerve plexus. Most of the cases have been asymptomatic but occasionally present as an obstructive mass. Abdominal investigations are effective in some cases, but usually, they are not informative. A significant number of cases have been detected after their operation by histopathology examination. Immune and histochemical staining shows the spindle cells that have been positive for S-100 and vimentin, but negative for CD34 and smooth muscle actin. If the diagnosis of Schowannoma is confirmed preoperatively, segmental resection is recommended. In this case report, we presented a 58-year-old woman with pelvic mass and normal colonoscopy that mimic extramural large uterine myoma with extraluminal pressure effect on the rectosigmoid.

Background: Helicobacter pylori (H. pylori), a spiral-shaped bacterium colonizing the human stomach, is generally acquired in childhood. This pathogen is highly diverse and can be used as genetic markers for predict the history of human migrations. This study aimed to determine the genetic diversity of H. pylori isolates from patients with dyspepsia by the multi-locus sequence typing (MLST) and update data on the prevalence of H. pylori among Iranian dyspeptic patients. Materials and Methods: In this descriptive cross-sectional study, 165 gastric biopsy specimens were obtained from patients with dyspepsia referred to Dr. Shariati Hospital of Isfahan, Iran, from April to July 2018. The status of H. pylori infection was determined by FISH in paraffin-embedded biopsy specimens. MLST of seven housekeeping genes was performed for 20 H. pylori isolates. The phylogenetic tree was plotted using CLC v8 and iTol software. Results: The overall prevalence of H. pylori infection was 53.3%. In the results of the analysis of MLST, a total of 14 new STs were recorded. The results of the global analysis showed that all the isolates, with a wide diversity, have a genetic affinity with members of the European population, such as Italy and Russia, and are in the hpEurope haplotype. Conclusion: Given the high prevalence of H. pylori infection in this region, early and accurate identification of patients seems necessary. Sequence analysis and determination of the origin of the phylogeny of strains can be effective in clinical management and monitoring of risk factors for chronic and recurrence of infection.

Introduction: We aimed to evaluate the effect of shock wave therapy on the improvement of symptoms and function of patients with Dupuytren's contracture. Materials and Methods: This research is a pre-post intervention study, conducted among patients referred to the physical medicine clinics of Isfahan during 2019–2020. In this study, subjects experienced shock wave therapy for 6 sessions, each in a week, and improvement of symptoms and function were assessed and compared after the period of study and follow-up (before treatment, 6 weeks after treatment, and 14 weeks after treatment). The pain visual analog scale and disabilities of the arm shoulder and hand questionnaire were completed for all patients at the mentioned time, and the finger contraction angle was also measured by a goniometer over these intervals. Results: Twenty patients, 11 (55%) men and 9 (45%) women participated in the study. The mean and standard deviation of their age was 66.6 ± 7.11 years. The trend of pain severity of patients was continuously and significantly decreasing up to 14 weeks, which implies the effectiveness of the intervention (P < 0.05). Moreover, the patients' functional status improved due to the continuation of the intervention, and its trend was decreasing up to 14 weeks (P < 0.05). As for the contraction angle, there was a continuous and significant decreasing trend until week 14, and the intervention was also effective on the contraction angle (P < 0.05). Conclusion: It can be concluded that shock wave therapy can be effective in improving the symptoms and function of patients with Dupuytren's Contracture.

Background: COVID-19 pandemic placed immense pressure on health systems. The current study aimed to evaluate the symptoms of COVID-19 in Isfahan province and their association with disease outcome. Materials and Methods: In this cross-sectional study, which was conducted on patients with a definite diagnosis of COVID-19, as a part of the investigations performed by the Deputy for Public Health of the Isfahan University of Medical Sciences, the frequency of underlying diseases, and general, respiratory, gastrointestinal, neurological, renal, cardiac, dermal, hearing symptoms are assessed using a checklist. The participants were followed up 1 month after definitive diagnosis, and the outcome of the disease (recovery or death) was recorded. Results: Of 300 patients, 143 (47.4%) were male and 157 (52.6%) were female. The mean age of patients was 43 ± 17.84 years. Muscle pain and fatigue were the most common early symptoms (63% and 60.3%, respectively). Age, sex, level of education, and occupation of patients and general, respiratory, and gastrointestinal symptoms and underlying diseases of respiratory disease showed a statistically significant association with the disease outcome (P < 0.05). Conclusion: General, respiratory, and gastrointestinal symptoms were associated with an increased risk of death due to COVID-19. General, visual, and hearing symptoms, and diabetes, cardiovascular diseases, and respiratory disease had a statistically significant association with the hospitalization of patients.

Background: The aim of this study was to evaluate ultra-widefield (UWF) fundus fluorescein angiography (FFA) findings in patients with Fuchs' uveitis syndrome (FUS). Materials and Methods: This cross-sectional study was conducted in patients with FUS. All the patients underwent a complete ophthalmologic examination, and FFA was carried out with Optos UWF retinal imaging. Standard FFA and image acquisition consisted of early phase (15–45 s) images, and late-phase (5–10 min) images were also obtained for both eyes. Results: Forty eyes from twenty unilateral FUS patients, including 11 females (55%), who had a mean age of 38.50 ± 6.97 years, were enrolled. Eighty-five percent of the FUS eyes had optic disc hyperfluorescence (ODH) in the FFA. A significant relationship was observed between ODH and iris heterochromia (P = 0.004). ODH was seen in all the patients with iris heterochromia (n = 16). Peripheral vascular leakage (PVL), capillary nonperfusion, chorioretinal scar, and vascular sheathing were observed in 3, 3, 2, and 8 of the patients' eyes, respectively. Conclusion: UWF FFA imaging seemed to be mandatory for evaluating the prognosis of the FUS patients, and another investigation may require to be conducted to evaluate the effect of antivascular endothelial growth factor agents for the management of PVL in these patients.
