DOI
:10.4103/abr.abr_281_21
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.

Adv Biomed Res
2022, 11:35 (29 April 2022)
DOI
:10.4103/abr.abr_289_21
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.

DOI
:10.4103/abr.abr_165_21
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.

Adv Biomed Res
2022, 11:33 (29 April 2022)
DOI
:10.4103/abr.abr_194_21
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.

Sepideh Tousizadeh, Mohsen Arbabi, Elaheh Tondro, Morteza Sedehi, Arman Arbabi
Adv Biomed Res
2022, 11:30 (29 April 2022)
DOI
:10.4103/abr.abr_55_21
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:
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.

DOI
:10.4103/abr.abr_258_20
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.

The effect of orexin-2 and endocannabinoid-1 antagonists on neuronal activity of hippocampal CA1 pyramidal neurons in response to tramadol in rats
Vajihe Imanpour, Parham Reisi
Adv Biomed Res
2022, 11:26 (30 March 2022)
DOI
:10.4103/abr.abr_65_21
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.

Evaluation of plasma fibrinogen levels before and after coronary artery bypass graft surgery and its association with the need for blood products
Azim Honarmand, Keivan Bagheri, Alireza Hoghooghy, Kazem Rezaei
Adv Biomed Res
2022, 11:25 (30 March 2022)
DOI
:10.4103/abr.abr_22_21
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.

The acute effects of different doses of tramadol on neuronal activity of medial prefrontal cortex in rats
Neda Hasanpour Razmanjani, Parham Reisi
Adv Biomed Res
2022, 11:24 (30 March 2022)
DOI
:10.4103/abr.abr_17_21
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.

DOI
:10.4103/abr.abr_101_21
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.

Possibility of applying heart rate variability as a screening method to high-risk obstructive sleep apnea patients
Majid Malekmohammad, Parisa Adimi Naghan, Batoul Khoundabi, Shideh Omidian
Adv Biomed Res
2022, 11:22 (21 March 2022)
DOI
:10.4103/abr.abr_243_20
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.

Adv Biomed Res
2022, 11:21 (1 March 2022)
DOI
:10.4103/abr.abr_253_20
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.

DOI
:10.4103/abr.abr_258_21
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.

2022, 11:19 (28 February 2022)
DOI
:10.4103/abr.abr_197_20
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

DOI
:10.4103/abr.abr_164_20
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.

Ilnaz Rahimmanesh, Razieh Fatehi, Hossein Khanahmad
Adv Biomed Res
2022, 11:17 (28 February 2022)
DOI
:10.4103/abr.abr_201_20
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.

DOI
:10.4103/abr.abr_206_20
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.

DOI
:10.4103/abr.abr_178_20
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.

Adv Biomed Res
2022, 11:13 (28 February 2022)
DOI
:10.4103/abr.abr_100_20
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.

:10.4103/abr.abr_46_20
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.

DOI
:10.4103/abr.abr_152_20
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.

DOI
:10.4103/abr.abr_33_21
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.

2022, 11:8 (31 January 2022)
DOI
:10.4103/abr.abr_284_21
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.

:10.4103/abr.abr_79_21
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.

Adv Biomed Res
2022, 11:1 (31 January 2022)
DOI
:10.4103/abr.abr_305_20
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.
