BACKGROUND: Altmetrics is a newly emerging scholarly tool measuring online attention surrounding scientific research outputs. With respect to increasing demand of disseminating research findings on the World Wide Web, this study aims to analyze the altmetric statues of Iranian medical journals. METHODS: On February 27, 2019, the list of Iranian medical journals extracted from http://journals.research.ac.ir/ and consequently altmetric data token out from Altmetric database (Altmetric LLP, London, UK). The science mapping done via keyword co-occurrence, co-citation and co-authorship, network analysis using the VOSviewer. The Pearson coefficient was then employed for the correlation analysis using R. RESULTS: Among a total of 104 journals, 7518 articles were mentioned in Altmetric data resources (Mean: 72.28, Confidence Level (95.0%): 16.8), total mentions were 27577 (Mean: 265.16, Confidence Level (95.0%): 79.9). Considering the total mentions of articles, International Journal of Preventive Medicine achieved the first rank, followed by Journal of Research in Medical Sciences and Iranian Journal of Public Health. Notably, Twitter was the most popular altmetric resource followed by Facebook and news outlets. Tweets were generally from the United States and United Kingdom. Among top 5% popular Iranian medical articles multiple sclerosis, cancer, and anxiety was hot topics. CONCLUSIONS: Iranian biomedical journal editors and research scientists needs to be more dynamic in World Wide Web using social media, post-publication peer review tools, Stack Exchange (Q and A) sites, research highlight tools, Wikipedia, and etc. In spite, more attention to the concept of evidence-based policymaking, by Iranian government along with the health policymakers seems necessary.

Obesity is commonly associated with immunometabolic dysfunctions. Activation of inflammatory macrophages through TLR4 (toll-like receptor 4) and the anti-inflammatory impact of exercise have been and are the new concerns among researchers. A new short-term combined high-intensity interval training was proposed in young sedentary overweight/obese females. All participants were allocated to one of two groups: the exercise group (EG) and the control group (CG), where the EG participated in a 2-week combined training and the CG continued its routine lifestyle. Gene expression levels of <i>TLR4</i>, <i>NF-κB</i>(nuclear factor κB), and <i>IRF3</i> (interferon regulatory factor 3) were assessed by real-time PCR. Physiological, anthropometric, and biomedical metabolic factors were assessed. The between-group comparisons indicated a tendency to a decrease in <i>NF-κB</i> gene expression in the EG. The <i>IRF3</i> levels were not significantly changed compared to CG and the levels before training. Fasting glucose levels and β-cell function revealed a significant improvement in EG. These findings indicated that this protocol decreased meta-inflammation levels and improved insulin resistance independent of body composition changes. Consequently, combined training may be recommended as a therapeutic approach in metabolic diseases.

BACKGROUND: Schools provide an opportunity for developing strategies to create healthy food environments for children. The present study aimed to analyze the Healthy School Canteen (HSC) policy and identify challenges of its implementation to improve the school food environment in Iran. METHODS: This mixed method study included two qualitative and quantitative phases. In the qualitative phase, triangulation approach was applied by using semi-structured interviews with key informants, documents review and direct observation. Data content analysis was conducted through policy analysis triangle framework. In the quantitative phase, food items available in 64 canteens of primary schools of Tehran province were gathered. The food's nutrient data were evaluated using their nutrition facts label. The number and proportion of foods that met the criteria based on Iran's HSC guideline and the World Health Organization nutrient profile model for the Eastern Mediterranean Region (WHO-EMR) were determined. RESULTS: The main contextual factors that affected adoption of HSC policy included health (nutritional transition, high prevalence of non-communicable diseases and unhealthy food environment in and around the schools), political (upstream supportive policies and joint memorandums about health children between the Ministry of Health and Medical Education and Ministry of Education), structural (the lack of unified stewardship, inadequate human resource capacity, poor inter-sectional cooperation), economic (school financial problems, poor fiscal supportive of food policies), and socio-cultural (mothers working outside the home, the role of children's peer group, low nutrition knowledge of school principals) factors. Assessment of the school canteens showed that a large proportion of available foods did not comply with the national guidelines (54.7 ± 2.54%) and WHO-EMR model (85.6 ± 2.34%). The main reasons identified for incomplete implementation of the policy were inadequate physical and economic infrastructure to set up ...
