Nutritional status and changes in muscle and adipose tissue determined by computed tomography as predictors of mortality in hospitalized patients.

The aim of the present study was to investigate whether nutritional status and changes in muscle and adipose tissue determined by computed tomography are predictors of mortality in hospitalized patients. This was a prospective cohort study involving patients ≥ 20 years of age hospitalized in a public hospital. Sociodemographic and clinical variables were collected from electronic medical records.

Changes in body composition of burn patients during the phases of response to trauma.

Objective: To assess the changes in body composition of burn patients through electrical bioimpedance in the phases of response to trauma.

Methods: a longitudinal observational study, carried out from October 2019 to March 2020. Sociodemographic, clinical, epidemiological, anthropometric and body composition data were collected.

Association between being underweight and excess body weight before SARS coronavirus type 2 infection and clinical outcomes of coronavirus disease 2019: Multicenter study.

Objectives: The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2.

Methods: A multicenter cohort study was conducted in eight different states in northeastern Brazil. Demographic, clinical (previous diagnosis of comorbidities), and anthropometric (self-reported weight and height) data about individuals who tested positive for COVID-19 were collected.

Clinical and nutritional predictors of hospital readmission within 30 days.

Background/objectives: Identify clinical, sociodemographic, and nutritional predictors of hospital readmission within 30 days.

Subjects/methods: A longitudinal study was conducted with patients hospitalised at a public institution in Recife, Brazil. Sociodemographic (age, sex, race, and place of residence), clinical (diagnosis, comorbidities, medications, polypharmacy, hospital outcome, hospital stay, and occurrence of readmission within 30 days), and nutritional (% of weight loss, body mass index, arm circumference [AC], and calf circumference [CC]) characteristics were collected from the nutritional assessment files and patient charts.

Discriminative power of an adapted version of Nutritional Risk Screening 2002 applied to Brazilian older adults.

Objective: To investigate the discriminative power of Nutritional Risk Screening 2002.

Methods: A cross sectional study involving one hundred participants aged ≥60 years. The original and adapted versions of Nutritional Risk Screening 2002 and the Mini Nutritional Assessment were used.

Nutritional risk among surgery patients and associations with hospital stay and postoperative complications.

Introduction And Objectives: Nutritional Risk Screening (NRS 2002) is employed to identify nutritional risk in the hospital setting and determine which patients would benefit from nutritional support. The aim of the present study was to identify nutritional risk in patients admitted to the surgery ward and determine possible associations with hospital stay and postoperative complications.

Methods: Three hundred fifteen surgery patients were evaluated in the first 24 hours since admission.

Clinical-nutritional evolution of older women submitted to Roux-en-Y gastric bypass.

The aim of the present study was to describe the clinical- nutritional evolution of older women submitted to Roux-en-Y gastric bypass surgery. A concurrent, retrospective study was conducted involving a sample of 16 older women with morbid obesity submitted to Rouxen- Y gastric bypass surgery between 1997 and 2010. Weight, body mass index (BMI), percentage of weight loss (%WL) and percentage of excess weight loss (%EWL) were evaluated three, six and 12 months after surgery.
