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.

Mohsen Reisi, Niloufar Sharif Ahmadian, Mahin Hashemipour, Neda Mostofizadeh, Majid Keivanfar, Elham Hashemi
Adv Biomed Res
2022, 11:62 (29 July 2022)
DOI
:10.4103/abr.abr_285_20
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.

Ali Haji Gholami, Hourieh Ansari, Farshad Fardani
Adv Biomed Res
2022, 11:61 (29 July 2022)
DOI
:10.4103/abr.abr_263_21
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.

α-Pinene influence on pulpal pain-induced learning and memory impairment in rats via modulation of the GABAA receptor
Forouzan Rafie, Razieh Kooshki, Mehdi Abbasnejad, Iran Rahbar, Maryam Raoof, Amir Hossein Nekouei
Adv Biomed Res
2022, 11:60 (29 July 2022)
DOI
:10.4103/abr.abr_139_21
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.

Extraction and fractionation of the seaweed
Sargassum plagyophylum
and evaluation of fractions on depression induced by interferon alpha in mice
Azadeh Mesripour, Ehsan Gholamzadeh, Afsaneh Yegdaneh
Adv Biomed Res
2022, 11:59 (29 July 2022)
DOI
:10.4103/abr.abr_186_21
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.

Elaheh Zadeh Hosseingholi, Saeede Maddahi, Sajjad Jabbari, Ghader Molavi
Adv Biomed Res
2022, 11:58 (29 July 2022)
DOI
:10.4103/abr.abr_178_21
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.

DOI
:10.4103/abr.abr_154_20
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.
