Randomized Controlled Trial
Magnesium treatment on methylation changes of transmembrane serine protease 2 (TMPRSS2).
The viral entry of SARS-CoV-2 requires host-expressed TMPRSS2 to facilitate the viral spike protein priming. This study aims to test the hypothesis that magnesium (Mg) treatment leads to DNA methylation changes in TMPRSS2. ⋯ Among individuals ages < 65 y with calcium-to-magnesium intake ratios equal to or over 2.6, reducing the ratio to around 2.3 increased 5-methylcytosine modifications (i.e., cg16371860) and reduced 5-hydroxymethylcytosine modifications (i.e., cg26337277) in the TMPRSS2 gene. These findings, if confirmed, provide another mechanism for the role of Mg intervention in the prevention of COVID-19 and treatment of early and mild disease by modifying the phenotype of the TMPRSS2 genotype.

Responsiveness of one-carbon metabolites to a high-protein diet in older men: Results from a 10-wk randomized controlled trial.
Dietary strategies to promote successful aging are divergent. Higher-protein diets are recommended to preserve skeletal muscle mass and physical function. Conversely, increased B-vitamin intake, supporting one-carbon (1C) metabolism, reduces the risk of cognitive decline and cardiovascular disease. On the hypothesis that higher protein intake through animal-based sources will benefit 1C regulation by the supply of B vitamins (folate, riboflavin, and vitamins B6 and B12) and methyl donors (choline) despite higher methionine intake, this study explored the effect of a higher-protein diet on 1C metabolite status in older men compared to current protein recommendations. ⋯ Adding to the known benefits of higher protein intake in older people, this study supports a reduction of homocysteine with increased consumption of animal-based protein, although the health effects of differential response of choline metabolites to a higher-protein diet remain uncertain.

There are concerns about adverse events related to early enteral nutrition (EN) in people receiving extracorporeal membrane oxygenation (ECMO). This was a retrospective study evaluating. This nutritional support of people receiving ECMO, factors that may confer benefits in outcomes. ⋯ Although adequate nutritional support and EN-dominant nutritional support were not associated with changes in outcome, early EN was associated with reduced in-hospital mortality. Therefore, even when EN is not the dominant route of nutritional support, early EN may be recommended for better outcomes in people on ECMO.

Child stunting concurrent with wasting or being overweight: A 6-y follow up of a randomized maternal education trial in Uganda.
There is paucity of longitudinal data on combined anthropometric deficiencies in children. Herein, we present data on child stunting concurrent with wasting or being overweight among children in a 6-y follow-up study of a maternal education trial in rural Uganda. ⋯ The prevalence of stunting concurrent with wasting or being overweight remained low during the observation period. The intervention may have reduced concurrent stunting and being overweight over time.

Our primary objective was to explore the effect of a eucaloric ketogenic diet (EKD) on mortality, admission to the intensive care unit, and need for non-invasive ventilation in hospitalized patients with COronaVIrus Disease 19 (COVID-19), in comparison to a eucaloric standard diet. Secondary objectives were verification of the safety and feasibility of the diet and its effects on inflammatory parameters, particularly interleukin-6. ⋯ These results show a possible therapeutic role of an EKD in the clinical management of COVID-19. Currently, a prospective controlled randomized trial is running to confirm these preliminary data.
