Background: The aim of this study was to investigate the effects of whole-body electrical muscle stimulation (WB-EMS) training on inflammatory and anti-inflammatory cytokines in overweight men. Methods: We divided 30 participants into EMS and control groups. The training program for the EMS group comprised 20 WB-EMS sessions (7 weeks, three sessions per week). Results: The results showed that EMS training caused significant increase in interferon γ (P<0.001) and interleukin 10 (IL-10; P<0.01) and significant decrease in IL-17 and IL-23 (P<0.05). Also, the lipid profile showed significant positive changes in the EMS training group. Conclusion EMS training, a novel exercise method that uses electric stimulation, can affect the levels of various cytokines that are involved in inflammation and immunity. EMS training can have both beneficial and harmful effects on the body depending on the type and balance of involved cytokines.

PURPOSE: This study aimed to investigate the possible association between psychological disorders and risky driving behavior (RDB) in Iran. METHODS: This case-control study conducted in Shiraz, Iran in 2021. The case group included drivers with psychological disorders and the control group included those without any disorders. The inclusion criteria for selecting patients were: active driving at the time of the study, being 18 - 65 years old, having a driving license, having a psychological disorder including depression, bipolar disorder, anxiety spectrum disorder, or psychotic disorder spectrum confirmed by a psychiatrist, and completing an informed consent form. The exclusion criterion was the existence of conditions that interfered with answering and understanding the questions. The inclusion criteria for selecting the healthy cases were: active driving at the time of the study, being 18 - 65 years old, having a driving license, lack of any past or present history of psychiatric problems, and completing an informed consent form. The data were gathered using a researcher-made checklist and Manchester driving behavior questionnaire. First, partition around medoids method was used to extract clusters of RDB. Then, backward logistic regression was applied to investigate the association between the independent variables and the clusters of RDB. RESULTS: The sample comprised of 344 (153 with psychological disorder and 191 without confirmed psychological disorder) drivers. Backward elimination logistic regression on total data revealed that share of medical expenditure ≤ 10% of total household expenditure (OR = 3.27, 95% CI: 1.48 - 7.24), psychological disorder (OR = 3.08, 95% CI: 1.67 - 5.70), and substance abuse class (OR = 6.38, 95% CI: 3.55 - 11.48) were associated with high level of RDB. CONCLUSION Substance abuse, psychological illnesses, and share of medical costs from total household expenditure were found to be main predictors of RDB. Further investigations are necessary to explain the impact of different psychological illnesses on driving behavior.

Purpose: Bisphosphonates (BPs) have a powerful effect on reducing bone resorption and improving the survival of patients with breast cancer. We aimed to investigate the impact of BP treatment on the prevention of recurrence, metastasis, and death of breast cancer survivors in the perimenopausal period. Methods: The search strategy aimed to identify both published and unpublished studies in PubMed, Web of Science, Scopus, Embase, ProQuest, and Google Scholar in March 2021. Two independent reviewers assessed quantitative papers selected for retrieval for methodological validity before being included in the review using standardized critical appraisal instruments from the Joanna Briggs Institute (JBI) Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI). Statistical meta-analysis was performed using Review Manager (RevMan) 5.4 statistical software when the data were homogenous.Meta-analysis was performed by calculating the effect size (hazard ratio; HR) and 95% confidence intervals (CIs). Results: Twenty-one studies were eligible for this systematic review and meta-analysis.The overall The HRs for disease-free survival (DFS) and overall survival (OS) in women who received BPs were 0.89 (95% CI, 0.83–0.97; p = 0.005), and 0.75 (95% CI, 0.63–0.89; p = 0.001), respectively. The results showed that BPs had a significant effect on the prevention of locoregional (HR, 0.64; 95% CI, 0.42–0.97; p = 0.04), bone (95% CI, 0.74–0.95; p ≤ 0.001), and distant metastases (HR, 0.77; 95% CI, 0.62–0.94; p = 0.01). In the subgroup analysis based on study design, the only insignificant HR in the included randomized controlled trials (RCTs) was that of locoregional metastasis. Conclusion Although BPs have a promising effect on DFS, OS, and bone metastasis of perimenopausal women survivors of breast cancer, more RCTs are needed to evaluate their effect on other survivors’ outcomes.

Objective: Depression affects people living with HIV (PLWH) compliance leading to poor control infection. Previous observational studies showed an anti-depression effect of green tea extract (GTE). The therapeutic effect of GTE on depression were investigated in PLWH receiving antiretroviral therapy (ART). Methods: Fifty PLWH on ART with diagnose of mild to moderate of depression, participated in a double-blind, placebo-controlled trial and underwent 12 weeks of treatment with either 400 mg GTE capsules or placebo twice daily. The Hamilton depression scale of patients was measured before, 6 weeks and 12 weeks after treatment in two groups. The primary outcome measure was performed to evaluate the efficacy of GTE in improving depressive symptoms. Results: The mean of Hamilton score showed a significant difference between the two groups after 12 weeks (P = 0.035). Repeated measures ANOVA test showed a significant effect for time × treatment interaction on the Hamilton mean score between the two groups (P = 0.000). Conclusion: It seems the use of GTE capsules in PLWH on ART is safe and could lead to greater and more rapid improvement in depressive symptoms than placebo. Thus it can be considered as an alternative therapy for mild to moderate depression. Further studies with higher sample size and longer follow-up and comparisons with other antidepressive drugs are warranted.

Background: No previous studies have assessed the psychometric properties of the 36-item version of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) in the Persian language of Iran. This study was designed and conducted to evaluate the validity and reliability of the Persian version using a sample of persons with multiple sclerosis in Ahvaz, Iran. Methods: The methodological study was conducted in two stages: First, the 36 items of the original WHODAS 2.0 were translated to create a Persian version, after which the translation validity and psychometric properties were tested. The factor structure of the instrument was also tested using exploratory and confirmatory factor analyses. Results: The intraclass correlation coefficients were very good to excellent, varying between 0.82 and 0.99 for the six domains, and all domains had Cronbach’s α reliability values of above 0.70. For construct validity, results showed negative and strong correlation between the total score of WHODAS 2.0 and the Multiple Sclerosis Quality of Life-54. Exploratory factor analysis divided the Persian version of WHODAS 2.0 into seven factors for multiple sclerosis patients. Conclusion The results of this study indicate that the Persian version of WHODAS 2.0 is a valid and reliable instrument to study the disabilities of people with multiple sclerosis.

Purpose: Neurogenic bladder dysfunction (NGB) has an impact on the quality of life, which made it an important research subject in preclinical studies. The present review investigates the effect of stem cell (SC) therapy on bladder functional recovery after the onset of spinal cord injury (SCI), multiple sclerosis (MS), Parkinson disease (PD), and stroke in rodent models. Methods: All experiments evaluated the regenerative potential of SC on the management of NGB in rodent models up to June 2019, were included. From 1,189 relevant publications, 20 studies met our inclusion criteria of which 15 were conducted on SCI, 2 on PD, 2 on stroke, and 1 on MS in the rodent models. We conducted a meta-analysis on SCI experiments and for other neurological diseases, detailed urodynamic findings were reported. Results: The common SC sources used for therapeutical purposes were neural progenitor cells, bone marrow mesenchymal SCs, human amniotic fluid SCs, and human umbilical cord blood SCs. There was a significant improvement of micturition pressure in both contusion and transaction SCI models 4 and 8 weeks post-SC transplantation. Residual urine volume, micturition volume, and bladder capacity were improved 28 days after SC transplantation only in the transaction model of SCI. Nonvoiding contraction recovered only in 56 days post-cell transplantation in the contusion model. Conclusions Partial bladder recovery has been evident after SC therapy in SCI models. Due to limitations in the number of studies in other neurological diseases, additional studies are necessary to confirm the detailed mechanism for bladder recovery.

Immunotherapy is the standard of treatment for long-life relief of symptoms of allergic rhinitis. Vitamin D may affect the outcomes of treatment. This study evaluated the clinical efficacy of subcutaneous allergen immunotherapy in adult patients with allergic rhinitis based on the serum level of vitamin D. Patients with persistent allergic rhinitis and positivity for skin prick test were evaluated by Sino-nasal Outcome Test (SNOT-22) and Mini Rhinoconjunctivitis Quality of Life Questionnaire (MiniRQLQ) before subcutaneous allergen immunotherapy and during the maintenance phase to assess the relation of the serum level of vitamin D and the clinical efficacy of immunotherapy. After immunotherapy, the greatest reduction in SNOT-22 scores were reported in patients with vitamin D sufficiency (39.0 ± 9.2), followed by vitamin D suboptimal provision (35.1 ± 12.1), insufficiency (25.0 ± 7.5), and deficiency (18.3 ± 6.0) (P < 0.001). The MiniRQLQ reduction in patients with vitamin D sufficiency, suboptimal provision, insufficiency, or deficiency was 30.7 ± 8.7, 27.1 ± 8.7, 20.0 ± 8.6, or 17.4 ± 7.1, respectively (P < 0.001). Both of SNOT-22 and MiniRQLQ scores decreased significantly following immunotherapy in patients with different levels of vitamin D. However, these effects were more pronounced when the level of vitamin D was sufficient.

OBJECTIVE: To determine the localization, expression, and function of Toll-like receptors (TLRs) in fallopian tube epithelial cells. METHODS: The localization of TLRs in fallopian tube epithelial cells was investigated by immunostaining. Surprisingly, the intensity of staining was not equal in the secretory and ciliated cells. After primary cell culture of fallopian tube epithelial cells, ring cloning was used to isolate colonies of ciliated epithelial cells, distinct from non-ciliated epithelial cells. The expression of TLRs 1–10 was examined by quantitative real-time polymerase chain reaction, and protein localization was confirmed by immunostaining. The function of the TLRs was determined by interleukin (IL)-6 and IL-8 production in response to TLR2, TLR3, TLR5, TLR7, and TLR9 ligands. RESULTS: Fallopian tube epithelial cells expressed TLRs 1–10 in a cell-type-specific manner. Exposing fallopian tube epithelial cells to TLR2, TLR3, TLR5, TLR7, and TLR9 agonists induced the secretion of proinflammatory cytokines such as IL-6 and IL-8. CONCLUSION: Our findings suggest that TLR expression in the fallopian tubes is cell-type-specific. According to our results, ciliated cells may play more effective role than non-ciliated cells in the innate immune defense of the fallopian tubes, and in interactions with gametes and embryos.
