Observational Study
Nutritional status of patients with COVID-19 1-y post-ICU stay: A prospective observational study.
Patients discharged from the intensive care unit (ICU) often experience physical complaints and poor nutritional intake, which negatively affect their nutritional status (NS). The aim of this study was to describe the NS of patients with COVID-19 1-y post-ICU stay. ⋯ Despite almost fully regained weight and good physical recovery in adult patients 1-y post-ICU stay, NS remained impaired because of elevated FMI, even though reported nutritional intake was below the estimated requirements.

We conducted a survey of pediatric nephrologists to examine the knowledge and current practices of and identify challenges in the nutritional management of critically ill children during continuous renal replacement therapy (CRRT). Although it is known that there is a significant effect on nutrition during CRRT, there seems to be a lack of knowledge as well as variability in the practices of nutritional management in these patients, as indicated by our survey results. ⋯ The results as well as the known effects of CRRT on metabolism should be considered during the development of guidelines in critically ill children on CRRT. Our survey findings also highlight the need for further research in the assessment of nutrition, determination of energy needs and caloric dosing, specific nutrient needs, and management.

Insulin resistance is a common risk factor for metabolic syndrome (MetS), leading to type 2 diabetes mellitus and cardiovascular diseases. This study tested the hypothesis that the polygenic variants associated with the risk of insulin resistance (IR) interact with the lifestyles and nutrient intake of participants aged >40 in a large city hospital-based cohort (n = 58 701). ⋯ Adults having a high PRS for IR may benefit from a PBD containing high amounts of fruits, V-C, and flavonoids, which were found inversely related to IR risk. The results can be applied to personalized nutrition.

This study aims to assess social determinants of stunting among children aged <5 y within the Malay ethnicity in Malaysia. ⋯ The prevalence of stunting among children of Malay ethnicity aged <5 in Malaysia necessitates immediate intervention. It is pertinent to facilitate early identification of those children at risk of stunting for additional care to promote healthy growth.

Multidrug resistance transporter 1 (Mdr-1) is a relevant component of the intestinal transcellular barrier that decreases absorption of oral drugs, thus modulating their bioavailability. Obese patients with metabolic disorders take medications that are subjected to intestinal metabolism and the Mdr-1-dependent barrier. This study evaluated the effect of a high-fat diet (HFD; 40% fat for 16 wk) on Mdr-1 expression and transport activity in C57BL/6 (C57) male mice. Comparable studies were performed in tumor necrosis factor α (TNF-α) receptor 1 knockout mice (R1KO) to delineate a possible role of TNF-α signaling. ⋯ This study demonstrated an impairment of the Mdr-1 intestinal barrier function induced by HFD as a consequence of downregulation of both Mdr-1 gene homologues, resulting in impaired Mdr-1 protein expression. Inflammatory response mediated by TNF-α receptor 1 signaling was likely involved.
