Ankle-brachial index and subclinical atherosclerosis in type 1 diabetes.
To assess the prevalence of altered ankle-brachial index (<0.9 or >1.3) in patients with type 1 diabetes and to compare it with the presence of subclinical atherosclerosis by carotid ultrasound. ⋯ Our study showed that vascular calcification (ankle-brachial index >1.4) was frequent in this population with type 1 diabetes and associated with subclinical atherosclerosis. A model combining ankle-brachial index >1.4 and age >35 years showed an excellent correlation with atherosclerosis and can assist in clinical suspicion and optimize the request for additional tests.

Commercial blood cell separation systems versus tube centrifugation methods for the preparation of platelet-rich plasma: a preliminary cross-sectional study.
Clinical studies claim that platelet-rich plasma (PRP) accelerates tissue healing due to its high concentration of growth factors and that the combination with leukocytes improves the antimicrobial effect of the concentrate. Most of these studies obtained PRP using different separation systems, and few analyzed the content of the PRP used for treatment. This study characterized the composition of PRP and white blood cells (WBC) from a single donor produced by three commercially available PRP separation systems and two anticoagulated general analytical tubes. ⋯ The Easy PRP Kit concentrates WBC-rich PRP, resulting in increased WBC concentrations, compared with low WBC-low PRP of GloPRP and general tube methods for EDTA and citrate analysis and the even lower concentration of PRP from the Wego Kit, with the absence of leukocytes.

Serum asprosin level in different subtypes of polycystic ovary syndrome: a cross-sectional study.
Polycystic ovary syndrome can be divided into different subtypes, including insulin resistance and hyperandrogenism. The aim of this study was to investigate the relationship between serum asprosin levels and polycystic ovary syndrome subtypes. ⋯ Our study shows that women with polycystic ovary syndrome hyperandrogenism or insulin resistance exhibit significantly lower serum asprosin levels compared with controls, and the lower asprosin level directly correlated with prolactin level.

Relationship between body mass index and waist-to-height ratio in childhood.
To evaluate whether there is an association between the body mass index z-score and waist-to-height ratio of children and adolescents. ⋯ There was a significant correlation between body mass index and waist-to-height ratio. This association was higher in adolescents. The waist-to-height ratio is easy to apply and may be useful as a predictor of cardiometabolic risk.
