Effect of vitamin K1 supplementation on coronary calcifications in hemodialysis patients: a randomized controlled trial.

Background: Chronic kidney disease (CKD) is associated with several adverse cardiovascular outcomes, including coronary heart disease, heart failure, and arrhythmias. The severity of arterial calcifications predicts the risk of coronary heart disease and increases the risk of premature cardiovascular death. In experimental models, vitamin K1 supplementation appears to reduce coronary artery calcifications.

Oral glucose tolerance test curve shape in Mexican children and adolescents with and without obesity.

Objectives: Mexican children with obesity are at a higher risk of developing type 2 diabetes mellitus (T2DM). The aim of the study was to compare oral glucose tolerance test (OGTT) characteristics: time of peak glucose, glucose level ≥155 mg/dL at 1 h, presence of metabolic syndrome (MetS), sensitivity, secretion, and oral disposition index (oDI) in children with and without obesity, according to oral glucose tolerance curve shape: monophasic or biphasic.

Methods: Cross-sectional study including 143 children.

Pancreatic beta cell function and insulin resistance profiles in first-degree relatives of patients with prediabetes and type 2 diabetes.

Aims: To evaluate insulin secretion and insulin resistance profiles in individuals with family history of prediabetes and type 2 diabetes.

Methods: This was a cross-sectional study to evaluate clinical and metabolic profiles between individuals with type 2 diabetes, prediabetes and their relatives. There were 911 subjects divided into five groups: (i) normoglycemic (NG), (ii) type 2 diabetes, (iii) prediabetes, (iv) first-degree relatives of patients with type 2 diabetes (famT2D), and (v) first-degree relatives of patients with prediabetes (famPD); anthropometrical, biochemical and nutritional evaluation, as well as insulin resistance and pancreatic beta cell function measurement was performed by oral glucose tolerance to compare between groups.

Correlation and comparison between different measurement sites of waist circumference and cardiovascular risk in children: a systematic review and meta-analysis.

Background: waist circumference (WC) is a component of metabolic syndrome (MetS) and an excellent marker for the risk of cardiovascular disease (CVD) in children. This study aimed to provide information on the anatomical measurement sites of WC and their comparative correlation with MetS and its components in children. Methods: the literature search included papers published between January 2005 and September 2023 that met the following criteria: pediatric patients (2-18 years), WC measurement at different anatomical sites (≥ 2), and CVD risk by MetS.
