Meta Analysis
Association between admission body mass index and outcomes in critically ill children: A systematic review and meta-analysis.
The association between nutritional status at pediatric intensive care unit (PICU) admission with clinical outcomes remains unclear. We conducted this systematic review to summarize the overall impact of PICU admission body mass index (BMI) on clinical outcomes. ⋯ Our systematic review did not reveal any association between PICU admission BMI status and outcomes in critically ill children. Further investigation with standardized nutrition status classification on admission, stratified by patient subgroups, is needed to clarify the association between nutritional status and clinical outcomes of PICU patients.

The high prevalence of obesity and obesity-related comorbidities has reached pandemic proportions, particularly in Western countries. Obesity increases the risk to develop several chronic noncommunicable disease, ultimately contributing to reduced survival. Recently, obesity has been recognized as major risk factor for coronavirus disease-19 (COVID-19)-related prognosis, contributing to worse outcomes in those with established COVID-19. ⋯ Such lifestyle strategies may ultimately reduce morbility and mortality in patients with infectious disease, especially in those with concomitant obesity. The aim of this review is to discuss how obesity might increase the risk of COVID-19 and potentially affect its prognosis once COVID-19 is diagnosed. We therefore advocate for implementation of strategies aimed at preventing obesity in the first place, but also to minimize the metabolic anomalies that may lead to a compromized immune response and chronic low-grade systemic inflammation, especially in patients with COVID-19.

Great interest has been raised by the possible protective role of vitamin D in coronavirus disease 2019 (COVID-19), but objective data on 25(OH)vitamin D deficiency in hospitalized COVID-19 patients are not conclusive. The aim of this study was to determine the prevalence of 25(OH)vitamin D deficiency in COVID-19 patients admitted to an Italian referral hospital and explore its association with clinical outcomes and the markers of disease severity. ⋯ Very low 25(OH)vitamin D levels were highly prevalent and suggestive of deficiency among our hospitalized severe COVID-19 patients, but low 25(OH)vitamin D levels were not associated with outcome variables. Whether 25(OH)vitamin D adequacy may influence clinical outcomes in COVID-19 and the unexpected correlation between higher 25(OH)vitamin D levels and mortality require further investigations by large intervention trials.

Observational Study
COVID-19 is associated with clinically significant weight loss and risk of malnutrition, independent of hospitalisation: A post-hoc analysis of a prospective cohort study.
Coronavirus disease 2019 (COVID-19) may associate with clinical manifestations, ranging from alterations in smell and taste to severe respiratory distress requiring intensive care, that might associate with weight loss and malnutrition. We aimed to assess the incidence of unintentional weight loss and malnutrition in COVID-19 survivors. ⋯ NCT04318366.

Vitamin D deficiency represents a pandemic health problem with a broad spectrum of clinical implications. Several studies have involved lower levels of vitamin D with inflammatory disorders including cardiovascular, autoimmune and infectious disease. Indeed, the pathophysiological mechanisms are still poorly ascertained. We aimed at evaluating the impact of cholecalciferol (25(OH)D) levels on the biomarkers of acute-phase response and inflammation in a large cohort of patients with cardiovascular disease. ⋯ The present study demonstrates that, among patients with cardiovascular disease, 25(OH)D deficiency is associated with a higher metabolic and clinical risk profile and with an elevation of cellular and humoral inflammatory parameters. Future dedicated studies should be, therefore, advocated in order to define whether 25(OH)D supplementation can modulate the mediators of the acute phase response and therefore potentially offer clinical and prognostic advantages on a broad spectrum of inflammatory disease.
