The effect of vitamin D supplementation on oxidative stress and inflammatory biomarkers in pregnant women: a systematic review and meta-analysis of clinical trials.

Background: Vitamin D deficiency, a common problem among pregnant women, is linked with maternal inflammation, oxidative stress and consequent adverse pregnancy outcomes. The aim of this systematic review was to evaluate the effect of vitamin D supplementation on oxidative stress and inflammatory biomarkers in pregnant women according to the PRISMA guidance.

Sugary beverages are associated with cardiovascular risk factors in diabetic patients.

Purpose: Sugar-sweetened beverages (SSBs) containing high amount of added sugars have increased over the last decades. Due to increased risk of cardiovascular events in type 2 diabetes mellitus (T2DM) patients, we designed a study to assess the association between SSBs and metabolic syndrome, a collection of cardiovascular risk factors, in these patients.

Methods: A cross-sectional study was performed on T2DM adults ( = 157).

Sugar-sweetened beverages consumption is associated with abdominal obesity risk in diabetic patients.

Aim: Sugar sweetened beverages (SSBs) are any beverages containing added-sugar and supposed to increase body lipogenesis and fat accumulation in healthy subjects. This study was performed to assess the possible association between SSBs consumption and obesity in type 2 diabetes (T2DM) patients.

Methods: T2DM adults with no insulin treatment entered the study.

Association of obesity with hypertension and dyslipidemia in type 2 diabetes mellitus subjects.

Aim: Obesity and diabetes are contributed to cardiovascular disease risk. The current study was performed to evaluate the association of central and general obesity and cardio-metabolic risk factors, including dyslipidemia and hypertension in T2DM patients.

Methods: This was a cross-sectional study in T2DM adults.

Mediterranean diet and metabolic syndrome prevalence in type 2 diabetes patients in Ahvaz, southwest of Iran.

Aims: Metabolic syndrome as a cardiovascular disease predictor, is proposed to be reduced by following a Mediterranean diet. This study was aimed to explore the relationships between metabolic syndrome and Mediterranean diet in type 2 diabetes mellitus patients.

Materials: A cross-sectional study was performed on 158 type 2 diabetes mellitus patients 28-75 years old (mean age: 54.
