Mechanisms of Intersectoral Collaboration in the Health System: A Scoping Review.

Background: The implementation of health interventions requires the collaboration of various sectors outside health due to the multidimensional nature of healthcare. Building effective partnerships demands the use of intersectoral mechanisms that facilitate the leadership and implementation of these programs. In this review, the mechanisms of intersectoral collaboration (ISC) and their results were identified. Methods: This scoping review was conducted in 2020. Using relevant keywords, all documents related to ISC in the health system were identified by searching four databases (PubMed, Scopus, Science Direct, and Web of Science), Google, and Google scholar search engines. In the initial search, 2911 documents were extracted. Based on the selection criteria 52 documents were selected for content analysis. Results: Five areas of ISC were identified, including funding (collection, pooling, and distribution of funds), governance and leadership (political commitment, rules and regulations, control and evaluation, and stakeholder engagement), structural mechanisms (interorganizational, government-based, and program-based structures), process tools (information tools, support tools, and resource and service sharing), and models and frameworks (general, national, and program-specific models). Conclusion: An intersectoral framework or model be developed that considers the financial, structural, and leadership aspects as well as the necessary process tools required for each program. Moreover, it should be considered communication and human resources empowerment in each intervention.

A comprehensive insight into the potential effects of resveratrol supplementation on SIRT-1: A systematic review.

BACKGROUND AND AIMS: Silent information regulator 1 (Sirt1) involved in histone stability, transcriptional activity, and translocation. This systematic review aimed to summarize the effects of Resveratrol on Sirt1 expression. MATERIALS AND METHODS: Electronic databases including Scopus, Medline and web of knowledge were searched up to March 2020. RESULTS: Out of 801 studies identified in our search finally 12 articles included. Totally six studies evaluated the effects of resveratrol on SIRT1 gene expression, and six articles investigate protein expression. CONCLUSION: The results of the included studies showed that resveratrol supplementation had beneficial effects on protein and gene expression of SIRT1.

Video game and motor-cognitive dual-task training could be suitable treatments to improve dual-task interference in older adults.

The objective of study was to investigate the effects of video game training in comparison with traditional motor-cognitive dual-task training on dual-task interference in older adults. Sixty older adults were allocated to the video game (intervention group) or the motor-cognitive dual-task training (control group). The outcome measures were dual-task cost (DTC) of linear metrics (Standard deviation (SD) of amplitude and velocity) and DTC of nonlinear metrics (approximate entropy, Lyapunov and correlation dimension) acquired from postural sway time series from both the mediolateral (ML) and anteroposterior (AP) directions. The results revealed in both groups, dual-task cost of SD of amplitude and velocity as well as Lyapunov were significantly decreased in post-training and follow-up compared with pre-training (p < 0.017), while there was no significant difference between the groups. Video game and motor-cognitive dual-task training could be recommended as suitable treatments to improve dual-task interference.

The effect of green coffee extract supplementation on lipid profile: A systematic review of clinical trial and in-vivo studies.

BACKGROUND AND AIMS: Dyslipidemia is an important and common risk factor for cardiovascular disease and increases the risk of mortality. Green coffee extract (GCE) contains bioactive polyphenols, especially Chlorogenic acid (CGA), that due to the antioxidant characteristic, have a desirable effect on metabolic factors. This review conducted to focus on the effect of GCE on lipid profiles. METHODS: PubMed, Scopus, and web of science were searched until November 2019. All clinical studies and in-vivo studies that provide sufficient information about outcomes include to this review. RESULTS: Out of 3270 studies obtained in our searching, only 32 articles were eligible for analysis. Five double-blind, randomized clinical trial studies, two Cross-over studies, one Quasi-experimental study, and twenty animal studies were included in this systematic review-all articles evaluated according to the checklist of aim and inclusion and exclusion criteria. Generally, the results of the included studies showed there is controversy about the effect of GCE and CGA on lipid profile improvement. CONCLUSIONS: Although, a higher dosage of GCE and administration of CGA with longer duration leads to better results. However, investigating the effectiveness and safety dosage as a lipid-lowering agent needs further studies with differential dosage and periods.

Effects of green coffee extract on fasting blood glucose, insulin concentration and homeostatic model assessment of insulin resistance (HOMA-IR): a systematic review and meta-analysis of interventional studies.

Many studies have investigated the relationship between coffee and diabetes. Evaluation of the current evidence on the effect of coffee intake on diabetes is critical. Therefore, we aimed to investigate the potential association between green coffee extract (GCE) and fasting blood glucose (FBG), insulin and homeostatic model assessment of insulin resistance (HOMA-IR) by pooling together the results from clinical trials. PubMed, Scopus and Google Scholar were searched for experimental studies which have been published up to December 2018. Randomized controlled trials (RCTs) that investigated the effect of GCE supplementation on FBG, insulin and HOMA-IR in adults were included for final analysis. A total of six articles were included in the meta-analysis. Results revealed that GCE supplementation reduced FBG level (SMD: -0.32, 95% CI - 0.59 to - 0.05, P = 0.02) but had no effect on insulin levels (SMD: -0.22, 95% CI -0.53 to 0.09, P = 0.159). Although analysis showed that GCE supplementation cannot change the HOMA-IR status (SMD: -0.30, 95% CI -0.73 to 0.13, P = 0.172), after stratified studies by GCE dosage (< 400 mg/day versus > 400 mg/day) there was a significant decrease in HOMA-IR status in a dose greater than 400 mg. These findings suggest that GCE intake might be associated with FBG improvement.

Effects of probiotics and synbiotic supplementation on antioxidant status: A meta-analysis of randomized clinical trials.

BACKGROUND AND AIM: Oxidative stress implicated in the pathogenesis of several diseases. Anti-oxidative characteristics of probiotics reported previously. Thus, we aimed to critically investigate the effectiveness of probiotics and synbiotics supplementation on antioxidant biomarkers. METHODS: A comprehensive search of Scopus and Medline was performed up to November 2017. All randomized controlled trials (RCT) which evaluate the effect of probiotics or synbiotics on superoxide dismutase (SOD) activity, total antioxidant capacity (TAC) and glutathione (GSH) levels were included. Weighted mean difference (WMD) were pooled using random effect model. RESULTS: Sixteen eligible RCTs with 915 participants were included in present study. Findings showed that probiotics could significantly increase GSH level compared to the control groups ((WMD): 132.36, 95% CI: 27.76, 236.95, P = 0.01). Because of considerable heterogeneity among included the studies, subgroup analyses were conducted. Subgroup analysis revealed that GSH level significantly increased in non-diabetic individuals; the effect size was not significant in diabetic patients. Furthermore, probiotics and synbiotics showed no significant effect on TAC level (WMD: 0.04, 95% CI: -0.07, 0.15, P: 0.50) and SOD activity (WMD: 0.04, 95% CI: -0.06, 0.13, P = 0.43). CONCLUSION: Probiotics and synbiotics supplementation improve GSH as a biomarkers of antioxidant status in the body. However, additional studies needed for concluding about TAC and SOD activity.
