Malnutrition is associated with clinical outcomes in mechanically ventilated patients with pneumonia and other lung manifestations: A retrospective cohort.

Background: Malnutrition is a highly prevalent condition in patients who are critically ill that has been previously associated with adverse clinical outcomes. The aims of this study are to describe the prevalence of malnutrition using Global Leadership Initiative on Malnutrition (GLIM) criteria and analyze the associations with clinical outcomes using original criteria or the presence of one phenotypic criterion with inflammation measured by C-reactive protein (CRP) in patients with pneumonia and other lung manifestations who are mechanically ventilated.

Methods: This retrospective cohort study included patients who are critically ill.

Zinc and selenium supplementation on treated HIV-infected individuals induces changes in body composition and on the expression of genes responsible of naïve CD8+ T cells function.

Background And Aim: Deficiency of zinc and selenium is common in persons living with human immunodeficiency virus (PLWHIV) and has been associated with the development of non-AIDS related comorbidities, impaired immune system function and mortality. Micronutrient supplementation on long-term-treated PLWHIV could bring potential clinical and immunological benefits improving their health status and quality of life. The aim of the present study is to analyze the effect of zinc and selenium supplementation on body composition, bone mineral density, CD4+ T-cell counts, metabolic profile and immune system status on clinical stable PLWHIV on long-term antiretroviral therapy (ART).

Association between longitudinal changes in phase angle and mortality rate in adults critically ill with COVID-19: A retrospective cohort study.

Background: Phase angle (PhA) obtained by bioelectrical impedance analysis (BIA) works as a predictor of clinical outcomes. Specific cutoff values for longitudinal changes and their relationship with clinical outcomes are still undetermined for patients with critical illness. Thus, the aim of this study was to analyze the association between longitudinal changes in PhA during intensive care unit (ICU) stay and all-cause 90-day mortality in patients critically ill with COVID-19.

Association between protein energy wasting and peritoneal membrane transport in peritoneal dialysis.

Background: fast peritoneal transport (FT) has been associated with peritoneal albumin loss and protein energy wasting (PEW); however, this relationship has not been fully studied. Aim: the aim of this study was to analyze the differences in nutritional parameters between fast-transport peritoneal membrane (FT-PET) and slow-transport peritoneal membrane (ST-PET), and analyze the association between FT-PET and PEW in peritoneal dialysis (PD) patients. Methods: a cross-sectional study of patients on PD.

Validity of bioelectric impedance analysis for body composition assessment in interstitial lung disease patients.

Background: changes in body composition (BC) are common in interstitial lung disease, which leads to an increased risk of complications and infections, and are associated with poor quality of life and worse outcomes. BC assessment is important to identify malnutrition and sarcopenia. However, gold-standard techniques are not available in all clinical settings.

Fluid Status Assessment in Critically Ill Patients with COVID-19: A Retrospective Cohort Study.

Fluid status (FS) is a diagnostic challenge in critically ill patients with COVID-19. Here, we compared parameters related to FS derived from cumulative fluid balance (CFB), bioelectrical impedance analysis (BIA) and venous congestion assessed by ultrasound (VExUS) to predict mortality. We retrospectively reviewed the medical records of individuals with severe pneumonia due to COVID-19 between July and November 2021 in a single center.

Feeding intolerance during prolonged prone position in overweight and obese patients with severe COVID-19.

Objective: the aim of this study was to compare the incidence rate of feeding intolerance (FI) during supine (SP) or prone positioning (PP) in critically ill COVID-19 patients. Methods: this was a retrospective cohort study of critically ill patients with overweight or obesity who received enteral nutrition (EN) in prone or supine positioning continuously during the first five days of mechanical ventilation. Nutritional risk, anthropometric measurements and body composition were assessed at the first 24 hours upon Intensive Care Unit (ICU) admission.

Association between kidney biopsy findings in CKD patients with diabetes and renal replacement therapy initiation, a perspective from a low-middle income country.

Kidney disease in diabetes mellitus is usually explained by diabetic kidney disease, but other superimposed etiologies occur frequently. The distinction between diabetic kidney disease and non-diabetic kidney disease can only be made by performing kidney biopsy. Our objective was to evaluate the association of diabetic kidney disease, non-diabetic kidney disease, or both with renal replacement therapy initiation.

[Nutrition and peritoneal dialysis: Fundaments and practical aspects for dietary prescription].

The number of patients with advanced / end-stage chronic kidney disease (ESRD) with some modality of renal replacement therapy (RRT) has been on the rise significantly. Peritoneal dialysis (PD) represents 11% of the world dialysis population. Different options for RRT have been associated with a greater risk of developing complications, such infections, metabolic alterations and nutritional complications, specifically a higher incidence of protein-energy wasting (PEW), ranging from 32 to 49% in PD patients.

Low phase angle is associated with 60-day mortality in critically ill patients with COVID-19.

Background: Malnutrition status, body composition indicators, and bioelectrical impedance analysis (BIA) parameters have been associated with increased risk of death in several pathologies. The aim of this study was to describe the associations between phase angle (PhA) indicators obtained by BIA with length of hospital stay, days on mechanical ventilation, and 60-day mortality in critically ill patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Methods: This is a prospective cohort of mechanically ventilated patients with coronavirus disease 2019 (COVID-19).

Phase angle as predictor of malnutrition in people living with HIV/AIDS.

Background: Phase angle (PhA), measured by bioelectrical impedance analysis (BIA) has been studied as an indicator of survival in people living with HIV (PLWH). However, it remains unclear whether PhA is associated with malnutrition or low CD4+ T-cell counts.

Objective: In this study, we assessed the discriminative capacity of PhA for malnutrition detection using Global Leadership Initiative on Malnutrition (GLIM) criteria in PLWH, aiming to propose cutoff points for this population.

High nutritional risk using NUTRIC-Score is associated with worse outcomes in COVID-19 critically ill patients.

Background: nutritional risk has been associated with worse outcomes at the critical care unit. The aim of this study was to describe the association between nutritional risk and length of stay, days on mechanical ventilation, and in-hospital mortality in patients infected with SARS-CoV-2. Methods: a retrospective cohort of ventilated, critically ill patients.

[Agreement between body composition techniques in children and adolescents: narrative review of the literature].

Body composition monitoring is important to understand the effect of diet, physical activity, illness and growth on body stores. Body composition determination by accuracy and reproducibility techniques is essential. The objective of this study was to analyze the agreement between body composition techniques in children and adolescents.

Zinc and selenium indicators and their relation to immunologic and metabolic parameters in male patients with human immunodeficiency virus.

Objectives: Micronutrient deficiencies are common among people living with HIV (PLWHIV). The clinical and immunologic consequences of micronutrient deficiencies have been poorly explored in the context of human immunodeficiency virus (HIV) infection. The aim of this study was to determine the prevalence of zinc and selenium deficiency (dietary intake and serum concentrations) and analyze their associations with absolute CD4+ T-cell counts, inflammation markers, and metabolic disorders in a cohort of antiretroviral-experienced HIV-infected individuals.

Phase angle and mid arm circumference as predictors of protein energy wasting in renal replacement therapy patients.
