The administration of botulinum toxin A (BTA) into the gastric wall has emerged as a novel endoscopic bariatric procedure. Although over 20 years have elapsed since the initial human trial of intragastric BTA injection, considerable debate remains surrounding the safety, efficacy, and procedural instructions of this approach. The current literature exhibits discrepancies in the methodologies employed across studies, including differences in the dosage of BTA administered, injection site, number and depth of injections, post-procedural dietary modifications, and follow-up duration. This study reviewed the state-of-the-art use of BTA for weight loss and focused on the clinical evidence of the therapeutic applications of BTA for obesity. Studies with consistent outcome measures and methodologies are necessary to thoroughly assess the potential effects of BTA on weight management.

Methods: A total of 104 patients with lumbar canal stenosis were enrolled in this randomized, double blinded clinical trial. Participants were randomized and divided into two groups: TXA (54 cases) and control (50 cases). In the TXA group, a TXA solution was used for washing and soaking, whereas, in the control group, irrigation of wound was with normal saline. IBL, pre- and postoperative coagulative studies, operation time, conventional hemostatic agent usage, systemic complications, and length of hospitalization were consecutively recorded. All participants were followed for an additional two months to gather data on their recovery status and time to return to work (RTW). Results: At baseline, there was no difference in clinical or lab findings, between the groups. IBL and use of hemostatic agents were significantly decreased in TXA group, as compared to the control group (p=0.001 and p=0.011, respectively). Systemic complications, length of hospitalization, and RTW were not significantly different between groups (p=0.47, p=0.38, and p=0.08, respectively). Conclusions This study showed that topical use of TXA during surgery may decrease IBL and minimize the use of hemostatic materials during posterior midline-approach laminectomy and discectomy, without increasing the potential for complications seen with intravenous TXA usage.

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: Studies of the effects of estrogens on the male reproductive system have emphasized the role of these hormones in male fertility. Sesame oil has many phytoestrogenic compounds and may improve male fertility. This study investigated the effects of sesame oil and different concentrations of estrogen on sperm parameters and DNA integrity in male mice. Methods: Twenty old NMRI (The Naval Medical Research Institute) male mice (40 weeks; weight, 30–35 g) were treated with sesame oil or different concentrations of estrogen (estradiol, 1 and 10 μL/kg/ day) or received no treatment (controls). After 35 days, sperm parameters and DNA integrity were assessed and analyzed. Results: Sperm count, progressive motility, and morphology were decreased in the group that received 10 μL/kg of estradiol. A remarkably lower percentage of DNA fragmentation and protamine deficiency were detected in the group that received 1 μL/kg of estradiol. In the groups that received sesame oil and 1 μL/kg of estradiol, the numbers of spermatogonia and Leydig cells were higher than in controls. The combination of sesame oil and 1 μL/kg of estradiol led to improved sperm parameters and chromatin and testicular structure. Conclusion Based on this study, consumption of sesame oil and a low concentration of estradiol may improve testicular function in older mice.

Type 2 diabetes mellitus (T2DM) is a serious public health problem accompanies with several complications. This study was conducted to evaluate the effects of chromium picolinate (CrPic) supplementation on the glycemic status and lipid profile in patients with T2DM. The patients with T2DM (n = 52) were randomly allocated into 2 groups. One group received 400 μg CrPic per day and the other group took placebo; the intervention duration was 8 weeks. Anthropometric indices and metabolic factors were measured at the beginning, and at end of the study. The patients were recommended not to change their normal diet, life style and medication. No significant changes were observed for weight, body mass index, and fasting blood glucose (FBG) in both groups; while intra-groups changes in homeostatic model assessment for insulin resistance (HOMA-IR) value was significant (p < 0.05). Results of analysis of covariance showed that there were significance differences between groups in total cholesterol, low density lipoprotein cholesterol and HOMA-IR at the end of the intervention adjusting for baseline levels (p = 0.035, 0.030 and < 0.001, respectively). In this study, oral supplementation with 400 μg CrPic for eight weeks did not alter FBG concentration as well as anthropometric parameters in individuals with T2DM. However, the modest beneficial effects of chromium supplementation on insulin resistance as indicated by HOMA-IR and lipid profile were found.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by major impairments in social communication, stereotyped and ritualistic behaviors and deficits in sensory reactivity. Recently, noninvasive brain stimulation (NIBS) methods, namely transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS), have been examined as possible new therapeutic options for modifying the pathological neuroplasticity involved in neuropsychiatric disorders including ASD. Therefore, we conducted a systematic review on the therapeutic uses of tDCS and repetitive TMS (rTMS) in ASD patients. A systematic search was performed on Scopus, Web of Science, PubMed, Cochrane and Embase. Original articles reporting the use of tDCS or rTMS to treat ASD were screened and studied by two researchers independently based on PRISMA guidelines. We found 32 eligible studies including 8 tDCS reports, 23 rTMS reports and one report with both tDCS and rTMS. These studies comprised 6 case-reports, 9 non-controlled trials and 17 controlled trials which assessed NIBS effects on the three cognitive, behavioral and biological dimensions in ASD. Existing evidence demonstrates that NIBS methods could be helpful for treating some dimensions of ASD such as repetitive behavior, sociability or some aspects of executive and cognitive functions. However, such evidence should be regarded with care because of the quality of original researches and serious publication bias as well as the heterogeneity of data. Further randomized, double-blind, sham-controlled trials with appropriate follow-up periods should be designed to assess the efficacy of NIBS methods for ASD treatment.

Curcumin is the principal polylphenol of turmeric that has been used to treat various disorders. However, its anti-obesity effects in patients with non-alcoholic fatty liver disease (NAFLD) remain controversial. Therefore, we aimed to perform a meta-analysis on the effects of supplementation with turmeric/curcumin on body weight, body mass index (BMI) and waist circumference (WC) in these patients. PubMed, Scopus, Cochrane Library, and ISI Web of Science were searched until January 2019, without any restrictions. Clinical trials that reported body weight, BMI and WC in patients with NAFLD were included. Weighted mean differences (WMDs) were pooled using a random-effects model. Eight studies (449 participants) fulfilled the eligibility criteria of the present meta-analysis. Overall, meta-analysis could not show any beneficial effect of turmeric/curcumin supplementation on body weight (WMD, −0.54 kg; 95% confidence interval [CI], −2.40, 1.31; p = 0.56; I² = 0.0%), BMI (WMD, −0.21 kg/m²; 95% CI, −0.71, 0.28; p = 0.39; I² = 0.0%) and WC (WMD, −0.88 cm; 95% CI, −3.76, 2.00; p = 0.54; I² = 0.0%). Subgroup analysis based on participants' baseline BMI, type of intervention, and study duration did not show any significant association in all subgroups. The results showed that turmeric/curcumin supplementation had no significant effect on body weight, BMI and WC in patients with NAFLD. Further studies with large-scale are needed to find out possible anti-obesity effects of turmeric/curcumin.

Examining the trend of anthropometric indices in children and adolescents in each region can be highly beneficial in providing effective strategies to improve the status of their growth. This study was conducted with the aim of determining the trend of anthropometric indices in students from primary to high school in the west of Iran. Data were collected using a demographic questionnaire and health certificates for anthropometric information of primary school students, and current anthropometric measurements with scale for high school students. Then, all of the data were analyzed in AnthroPlus and SPSS software. Of the 731 students, 350 were female and 381 were male. Mean height Z-score to age showed a significant reduction from primary to high school (from +0.0386 to −0.27416), and mean body mass index Z-score to age showed a significant increase (from −0.3916 to +0.1826). Prevalence of stunting and overweight/obesity in high school was 1.4 and 2.5 times higher than primary school, respectively, but the prevalence of wasting reduced by 2.3 fold. Girls were more affected by the increased trend of obesity and stunting compared to boys. Nutritional transition was evident in students. Healthcare policy-makers should design and implement a comprehensive health strategy to deal with this situation, especially in girls.
