Systemic sclerosis (SSc) is an autoimmune disease characterized by endothelial dysfunction with fibrosis of skin and internal organs. Integrity of the endothelial cell is important to its physiologic function such as production of angiogenetic factors. The aim of this study was to assess whether phase angle (PhA) is altered in patients with SSc and whether its values correlate with vascular endothelial growth factor (VEGF) and digital microvascular damage. ⋯ The evaluation of VEGF with PhA, NVC, and DUs could be useful to estimate cellular and microvascular damage in patients with SSc.

In obesity or anorexia, changes in body composition and mostly alterations in fat mass distribution are observed. The lymphatic system, which is implicated in fat absorption, might play a major role in the phenotype and development of these pathologies. In this study, two mice animal models were used: the high-fat diet model used for obesity and the activity-based anorexia model for anorexia. ⋯ Expression levels of lymphatic markers also were impaired in these models. Both obesity and anorectic models induced lymphatic system alterations mainly in the jejunum and ileum parts of the intestine. These alterations are associated with lipid absorption modifications.

Randomized Controlled Trial
Effects of synbiotic supplementation on microbiota-derived protein-bound uremic toxins, systemic inflammation, and biochemical parameters in patients on hemodialysis: A double-blind, placebo-controlled, randomized clinical trial.
The generation of key nephrovascular protein-bound uremic toxins, indoxyl sulfate and phenol, in hemodialysis (HD) patients is attributed to the dysbiotic gut microbiota. The aim of this study was to investigate the effects of synbiotic supplementation on serum levels of indoxyl sulfate, phenol, inflammation, and biochemical parameters in HD patients. ⋯ Synbiotic supplementation might increase indoxyl sulfate and parathyroid hormone levels in HD patients.

Leishmaniasis is a vector-borne infectious disease with a long history of infecting humans and other animals. It is a known emerging or resurging disease. The host nutritional state has an indispensable role in defense against pathogens. ⋯ The host and sandfly vector nutritional states could also influence the evolution of the parasite. It is essential to elucidate the roles that diets and nutrition play in the leishmanial life cycle. The aim of this article is to review the influences of nutrition and diets on the host susceptibility and severity of infection, preemptive and therapeutic strategy feedback, parasite evolution, and vector competence.

Randomized Controlled Trial
Zinc supplementation improves glucose homeostasis in patients with β-thalassemia major complicated with diabetes mellitus: A randomized controlled trial.
The development of abnormal glucose tolerance in β-thalassemia major (β-TM) is associated with alterations in the oxidant-antioxidant status. Zinc is an antioxidant and an essential element for insulin synthesis, storage, and secretion. This randomized controlled trial assessed the effect of oral zinc supplementation on glucose homeostasis in pediatric β-TM patients complicated with diabetes mellitus (DM). ⋯ Zinc supplementation as an adjuvant therapy in β-TM patients with DM reduced iron burden, decreased hyperglycemia, increased insulin secretion, and improved glycemic control without any adverse effects.
