Randomized Controlled Trial
Effects of probiotic yogurt on glycemic indexes and endothelial dysfunction markers in patients with metabolic syndrome.
The relationship between gut microflora and metabolic syndrome components such as obesity, low-grade chronic systemic inflammation, dyslipidemia, and altered glucose metabolism is now acknowledged. The aim of this study was to assess the effects of probiotic yogurt on glycemic indexes and endothelial dysfunction markers in patients with metabolic syndrome. ⋯ Consumption of probiotic yogurt improved fasting blood glucose and partly modified serum endothelial function markers. These results suggest that regular intake of probiotic yogurt may exert positive effects on the treatment of metabolic syndrome.

Multicenter Study
Neck circumference is associated with nutritional status in elderly nursing home residents.
Anthropometry is an easy and noninvasive method to evaluate nutritional status in institutionalized elderly people who are often bedridden. The aim of this study was to investigate the relationship between the neck circumference (NC) and nutritional status of elderly nursing home residents and to find cutoff points for NC size to identify individuals at risk of malnutrition. ⋯ NC is associated with other classical anthropometric parameters and malnutrition status in elderly people living in nursing homes.

Little is known about the indicators to assess malnutrition in patients with idiopathic pulmonary fibrosis (IPF). This study aimed to determine the following: 1) the prevalence of malnutrition in IPF patients; 2) the nutritional indicators predictive of low fat-free mass (FFM) as measured by bioimpedance analysis; 3) the IPF patients' characteristics associated with low FFM. ⋯ Malnutrition occurred in nearly one-third of IPF patients. Malnutrition screening should become systematic based on BMI and MAC, which are good clinical indicators of low FFMI. We propose a practical approach to screen malnutrition in IPF patients.

This study aimed to examine the cross-sectional association between dietary and serum selenium measures and depressive symptoms among a nationally representative sample of US adults. ⋯ Our study supports an inverse association between participants recommended dietary intake of selenium and depressive symptoms. Although results were not statistically significant for the association by quartile of serum selenium concentrations and depressive symptoms, a U-shaped association was identified.

Sex-specific differences in factors associated with aging and lifespan, such as sarcopenia and disease development, are increasingly recognized. The study aims to assess sex-specific aspects of the association between vitamin D insufficiency and low lean mass as well as between vitamin D insufficiency and the frailty phenotype. ⋯ We found notable sex-specific differences in the association of vitamin D insufficiency with low lean mass but not of vitamin D insufficiency with frailty. Vitamin D might play a relevant role in the loss of lean mass in men but not women and might be a biological marker of an unfavorable aging process associated with early development of frailty regardless of sex.
