Sepsis is a life-threatening condition characterized by multiorgan dysfunction due to an exaggerated host response to infection associated with a homeostatic failure. In sepsis, different interventions, aimed at improving clinical outcomes, have been tested over the past decades. Among these most recent strategies, intravenous high-dose micronutrients (vitamins and/or trace elements) have been investigated. ⋯ The best nutrient combination still needs to be determined, based on the antioxidant micronutrient network and the multiple interactions among different vitamins and trace elements. In addition, a better understanding of the pharmacokinetic and pharmacodynamic profiles of intravenous thiamine is needed. Future well-designed and powered clinical trials are urgently warranted before any specific recommendations can be made regarding supplementation in the critical care setting.

Observational Study
Malnutrition on admission is associated with trunk function recovery but not with lower limb muscle strength recovery in patients with acute stroke: an observational cohort study.
The aim of this study was to determine the effects of malnutrition on trunk function and lower leg muscle strength in patients with acute stroke upon hospitalization. ⋯ Malnutrition on admission leads to poor trunk function, but not lower leg muscle strength, in patients with acute stroke.

This study aimed to verify the performance of the triglyceride-glucose (TyG) index in predicting metabolic syndrome (MetS) using three different criteria in healthy individuals living in rural areas. In addition, it aimed to estimate the TyG index cutoff point in the prediction of MetS. ⋯ The TyG index proved to be valid for diagnosing MetS. The largest AUC of the TyG index was identified for the harmonized criteria. Thus, the TyG index can be used to diagnose MetS in individuals living in rural areas.

The aim of this study is to assess the changes in body mass index and waist circumference (WC) and their associations with sociodemographic, behavioral, and health characteristics in non-institutionalized older people in southern Brazil over a period of ≤6 y. ⋯ Despite the high proportion of older people who kept their body mass index and WC stable during this period, many of them lost body mass and gained WC. The findings also highlighted the importance of age in the nutritional changes observed in the population.

A study was carried out to identify characteristics of consumers of dairy products. ⋯ Among young people, as many as 39% do not follow the principles of healthy eating, and these are mainly women. Respondents' proinnovative attitudes and social status were conducive to increasing calcium intake and correlate with greater diversity in the consumption of dairy products. The Pearson correlation coefficient between body mass index and calcium intake was not significant (r = -0.03; P = 0.76).
