Phase angle is associated with nutritional risk in subacute stroke patients at the beginning of rehabilitation.

Objectives: Malnutrition in stroke is associated with poor clinical outcomes. Bioelectrical impedance analysis-derived phase angle (PhA) is widely used for assessing nutritional status as an index of muscle quality. This study aimed to evaluate the associations between whole body and limb PhAs and nutritional risk in stroke patients.

Controlling nutritional status score and geriatric nutritional risk index as a predictor of mortality and hospitalization risk in hospitalized older adults.

Background: The COntrolling NUTritional Status (CONUT) score and the Global Nutrition Risk Index (GNRI) are screening tools for assessing the risk of malnutrition based on widely available biochemical parameters. The primary objective of this study was to investigate the predictive value of CONUT and GNRI score on 36 months mortality and hospitalization risk in hospitalized older patients.

Methods: Data of 382 patients (196 women, mean age 80.

Low triiodothyronine is associated with high risk of malnutrition and poor functional status in subacute stroke patients.

Background And Aims: Stroke patients may exhibit low thyroid hormone (TH) levels and disease-related malnutrition, both potentially affecting clinical status; their relationships remain unexplored. This study aimed to evaluate TH concentrations in subacute stroke patients and investigate the relationships between TH levels, nutritional risk, and functional status.

Methods And Results: Early subacute stroke patients admitted to a rehabilitation unit were assessed using various nutritional screening tools (Geriatric Nutritional Risk Index-GNRI, Prognostic Nutritional Index-PNI, and Controlling Nutritional Status-CONUT score) and with the Global Leadership Initiative on Malnutrition (GLIM) criteria.

Bioelectrical impedance analysis (BIA) phase angle in stroke patients: A systematic review.

Background And Aims: Phase angle (PhA), a raw variable of bioelectrical impedance analysis (BIA), is an index of muscle structure and quality and might have a potential role in the evaluation of nutritional status. The aim of this systematic review was to evaluate in stroke patients: baseline PhA and its changes during hospital stay; the association of PhA with clinical features of patients, comorbidities, nutritional status or sarcopenia, and clinical outcomes.

Methods: Systematic research on electronic databases (PubMed, Scopus, and Web of Science) up to June 14th, 2024 was performed according to PRISMA checklist.

Propensity of hydroxide and hydronium ions for the air-water and graphene-water interfaces from ab initio and force field simulations.

Understanding acids and bases at interfaces is relevant for a range of applications from environmental chemistry to energy storage. We present combined ab initio and force-field molecular dynamics simulations of hydrochloric acid and sodium hydroxide highly concentrated electrolytes at the interface with air and graphene. In agreement with surface tension measurements at the air-water interface, we find that HCl presents an ionic surface excess, while NaOH displays an ionic surface depletion, for both interfaces.
