Arterial stiffness (AS) is a predictor of coronary artery outcomes in patients with cardiovascular disease (CVD). Carotid-femoral pulse wave velocity (cf-PWV) is a commonly used method for assessing AS. This study aimed to assess the relationship between cf-PWV and clinical CVD events. Of the 786 studies identified, 19 studies were included in the final meta-analysis. Meta-analysis revealed that participants with high cf-PWV by 1 standard deviation (SD), 1 m/s, and cutoff points have a high pooled relative risk for CVD events (1 SD: 1.25, 95% confidence interval [CI]: 1.19-1.31; 1 m/s: 1.12, 95% CI: 1.07-1.18; and cutoff points: 1.80, 95% CI: 1.45-2.14) and CVD mortality (1 SD: 1.23, 95% CI: 1.15-1.31; 1 m/s: 1.09, 95% CI: 1.04-1.14; and cutoff points: 1.85, 95% CI: 1.46-2.24). In addition, we found that the predictive value of increased AS was higher in patients with higher disease risk for total CVD events and CVD mortality than in other patients. Carotid-femoral pulse wave velocity is a useful biomarker to improve the prediction of CV risk for patients and identify high-risk populations who may benefit from aggressive CV risk factor management.
Objective. The aim of this study was to investigate the changes of regulatory T cells (Treg), interleukin-6 (IL-6), IL-10, transforming growth factor-β (TGF-β), and tumor necrosis factor-alpha (TNF-α) in patients with type 2 diabetes mellitus (T2DM). Methods. We performed a comprehensive search up to July 2016 for all clinical studies about the changes of Treg, IL-6, IL-10, IL-17, TGF-β, and TNF-α in T2DM patients versus healthy controls. Results. A total of 91 articles (5642 cases and 7378 controls) were included for this meta-analysis. Compared with the controls (all p < 0.001), the patients had increased serum levels of IL-6, TGF-β, and TNF-α but decreased the percentage of peripheral CD4+CD25+Foxp3+Treg and serum IL-10 level. Furthermore, the percentage of peripheral CD4+CD25+Foxp3+Treg (p < 0.001) and serum IL-10 level (p = 0.033) were significantly lower in the patients with complication and in the patients without complication, respectively. No significant changes about the percentage of CD4+CD25+Treg (p = 0.360) and serum IL-17 level (p = 0.459) were found in T2DM patients. Conclusions. T2DM patients have decreased the percentage of peripheral CD4+CD25+Foxp3+Treg and levels of serum IL-10 but elevated serum levels of IL-6, TGF-β, and TNF-α. Presence of diabetic complications further lowers the peripheral CD4+CD25+Foxp3+Treg number.
Aims/hypothesis The associations between adiponectin polymorphisms and type 2 diabetes have been studied widely; however, results are inconsistent. Methods We searched electronic literature databases and reference lists of relevant articles. A fixed or random effects model was used on the basis of heterogeneity. Sub-group and meta-regression analyses were conducted to explore the sources of heterogeneity.
Engagement in social activities is relatively low in rural areas, and associations of willingness and health-related quality of life with social participation were found. Policy-makers and government workers should make appropriate types of encouragement policies around social participation for older adults in rural areas. Geriatr Gerontol Int 2017; 17: 1593-1602.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
