Associations between Intensive care unit acquired weakness with post-extubation dysphagia and other clinical outcomes- a cohort study in critically ill respiratory patients.

Background: Intensive care unit-acquired weakness (ICU-AW) is a complication characterized by decreased muscle mass and impairments in strength and physical function and is associated with poor quality of life and worse clinical outcomes. The primary objective of this study is to analyze the prevalence of ICU-AW, and secondary objectives were to assess risk factors and analyze the associations with clinical outcomes.

Methods: This is a prospective cohort study of patients on mechanical ventilation (MV).

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.
