Phase angle as a marker of muscle quality: A systematic review and meta-analysis.

Background & Aims: Phase angle (PhA) is a biomarker derived from raw bioelectrical impedance analysis (BIA) values: resistance (R) and reactance (Xc). PhA reflects cellular membrane integrity and, as a result, has been considered a marker of fluid distribution, making it a potential prognostic indicator. A growing body of research demonstrates independent associations between PhA and muscle strength, mass, and composition.

Prognostic significance of novel muscle quality index utilization in hospitalized adults with cancer: A secondary analysis.

Background: This study aimed to investigate and propose novel approaches to calculate muscle quality index (MQI) using muscle mass derived from single-frequency bioelectrical impedance analysis (SF-BIA) and calf circumference in both unadjusted and body mass index (BMI)-adjusted forms. In addition, we examined their prognostic significance in patients with cancer.

Methods: A secondary analysis was conducted on a prospective cohort study of patients with cancer.

Body mass index-adjusted calf circumference is associated with mortality in hospitalized older patients with excess weight.

Objectives: Given the innovative nature of the method, our study aimed to assess the prognostic significance of body mass index (BMI)-adjusted calf circumference (CC) in older patients who are hospitalized.

Methods: This was a unique analysis as part of other cohorts comprising general hospitalized patients aged 60 years or older of both sexes. Only patients with excess weight (BMI ≥ 25 kg/m) were included.

Is phase angle associated with visceral adiposity and cardiometabolic risk in cardiology outpatients?

Background/objectives: Phase angle (PhA) serves as a prognostic marker in various clinical scenarios, reflecting oxidative stress and cellular damage. Despite its clinical relevance, its connection with adiposity and cardiovascular risk markers remains underexplored. Hence, our study sought to investigate the relationship between PhA and metabolic, adiposity, and cardiovascular risk parameters among outpatients with cardiology diagnosis.

Methods: This prospective study included patients ≥60 y of age. They were followed for 18 mo to assess mortality and hospital length of stay.

NUTRISCORE as a tool to predict greater weight loss and longer hospital stay in cancer patients.

Introduction: malnutrition in cancer patients is quite common and can cause various types of harm such as reduced tolerance to therapeutic measures and increased hospital stay. Identification of nutritional risk for these patients may minimize these problems. NUTRISCORE screening has been associated with Global Subjective Assessment Produced by Patient (ASG-PPP) screening, which is considered as the gold standard in cancer patients.

Is low phase angle a risk indicator for frailty and pre-frailty among community-dwelling older adults?

Studies investigating the association between the phase angle (PA) and frailty are scarce. The PA is considered a practical, low-cost, noninvasive measure for the early identification of this clinical condition. To investigate the association between PA and frailty/pre-frailty, nutritional and clinical aspects in older people.

Prevalence of metabolic syndrome in adolescents based on three diagnostic definitions: a cross-sectional study.

Objective: There is no consensus as to the best criterion for the evaluation of metabolic syndrome (MS), impairing the estimation of its prevalence. This study aims to compare MS estimates using three recommended definitions for adolescents based on a cross-sectional study nested in the Consortium of Brazilian Birth Cohorts in São Luís, Maranhão.

Subjects And Methods: A total of 2,515 adolescents aged between 18 and 19 years were evaluated.

Estimation of the availability of iron in the school meals of Municipal Centers for Early Childhood Education of a capital city in northeastern Brazil.

The final stage of Fe deficiency is Fe deficiency anaemia, with repercussions for human health, especially in children under 5 years of age. Studies conducted in Brazilian public daycare centres show high prevalence of anaemia. The present study aims to evaluate the availability of Fe in the meals of the Municipal Centers of Early Childhood Education in Maceió.

Vitamin D levels and their association with oxidative stress and inflammation markers in patients with cystic fibrosis.

Introduction: cystic fibrosis is a disease that causes inflammation, oxidative stress and metabolic changes that lead to nutrient deficiency, such as vitamin D deficiency. On the other hand, it is suggested that vitamin D has anti-inflammatory and antioxidant actions. Objective: to evaluate the prevalence of hypovitaminosis D and the association between serum 25 hydroxyvitamin D levels with markers of oxidative stress and inflammation in patients with cystic fibrosis.

Evaluation of ultrasonographic approaches aimed at determining distinct abdominal adipose tissue depots.

Objective: To analyze different anatomical sites in the abdominal region, in order to determine the positional parameter that identifies a higher level of visceral adipose tissue (VAT) and confers a greater cardiometabolic risk.

Materials And Methods: This is a methodological study in which VAT was evaluated by ultrasonography (USG) in three anatomical sites in the abdomen, while the abdominal circumference (AC) was measured using seven different protocols. Additionally, the glycemic and lipid profile, C-reactive protein, and the presence of systemic arterial hypertension were evaluated.

Food Intervention with Folate Reduces TNF-α and Interleukin Levels in Overweight and Obese Women with the C677T Polymorphism: A Randomized Trial.

Methylenetetrahydrofolate reductase () C677T polymorphism associated with body fat accumulation could possibly trigger an inflammatory process by elevating homocysteine levels and increasing cytokine production, causing several diseases.
