Background: Discordance (the presence of different categories of T scores in two skeletal sites of a single patient) can affect the physician’s decision to start medication or not. The present study was therefore conducted to assess the prevalence of T-score discordance between spine and femoral neck as well as its risk factors in a group of postmenopausal Iranian women. Methods: The present analytical cross sectional research was conducted based on the results of IROSTEOPs study on 8146 postmenopausal women referred to the bone mineral density (BMD) center of Shariati Hospital affiliated to Tehran University of Medical Sciences between 2000 and 2011. Based on their BMD results, the patients were categorized into three groups: Concordance and Minor and Major discordance. The factors affecting the risk of developing discordance was then studied through uni/and multivariate logistic regression. Results: Discordance between spine and femoral neck was reported in 3741 (45.9%) of the participants. Multivariate logistic regression revealed that older age, higher number of pregnancies and higher body mass index (BMI) are the main risk factors for T-score discordance at the studied sites. The use of hormonal replacement therapy (HRT) on the other hand played a protective role. Conclusion: It could be concluded that performing BMD at two different sites is necessary for the Iranian population, particularly postmenopausal women.

Background: Patients with type 2 diabetes mellitus are more prone to depression. Prevalence of depression in the Iranian results of studies is different. Therefore, the present study aims to study the prevalence of depression in Iranian patients with type II diabetes mellitus.

Methods: This study is a systematic review based on PRISMA guideline for systematic reviews and meta-analyses study. Literature searches of, Scopus, MEDLINE, PubMed, Science Direct, Cochrane, EMBASE, Web of Science, Springer, Online Library Wiley, Google Scholar search engine and Iranians database for publications in Persian and English were conducted up to December 2015. Searches were performed by two researchers independently using standard keywords. Reviewers extracted data and assessed methodological quality in duplicate.  Meta-analysis was performed using STATA, version 11.1 to combine data through Random Effects Model.

Results: Sixteen studies and 3,284 subjects with a mean age of 48.6 years were included in the analysis.  The prevalence of depression in Iranian patients with type II diabetes was estimated 54.8% (95% CI: 43.5- 66.1). This range for males and females were calculated 32.2 %( 95% CI: 16.3-48.1) and 60% (95% CI: 46.4-73.7), respectively. The highest prevalence of depression was in the center of Iran (60%) and the lowest rate was in the west of Iran (38%).

Conclusion: Regarding to high prevalence of depression in patients with type II diabetes, Implementation of screening program for psychiatric disorders, especially depression as well as conducted psychiatric consultation routinely for diagnosis and treatment of depression in these patients it seems necessary.

Background: The role of Wnts as mediators of pancreatic development has been confirmed, and exercise training may affect this process. Therefore, the present study aimed to investigate the effect of eight weeks of resistance training and moderate-intensity training on plasma Wnt3a, Wnt4, and pancreatic beta-cell count in streptozotocin-induced diabetic rats.
Methods: Twenty-four rats were divided into four groups: healthy control, diabetic control, diabetic + moderate-intensity continuous training, and diabetic + moderate-intensity resistance training. Diabetes was induced by intravenous injection of 110 mg nicotinamide and 40 mg streptozotocin per kg of body weight. The exercise training intervention was performed for eight weeks. Plasma Wnt3a and Wnt4 were measured by the ELISA method, and the number of beta cells was assessed by hematoxylin-eosin.
Results: Data analysis showed that the number of beta cells in the exercise group increased significantly compared to the diabetic control group (P<0.05). Also, a significant change was observed in the plasma levels of Wnt3a and Wnt4 in the exercise group compared to the healthy control group (P<0.05).
Conclusion: It seems that eight weeks of moderate-intensity continuous training and eight weeks of moderate-intensity resistance training probably caused the proliferation and protection of beta cells in response to an increase in Wnt3a and a decrease in Wnt4 in the diabetic rats.
