Background And Aim: Malnutrition is strongly related to mortality in intensive care unit (ICU) patients. The Patient- and Nutrition-Derived Outcome Risk Assessment Score (PANDORA) is a novel mortality prediction tool encompassing nutritional assessment. Since there is limited evidence regarding the power of PANDORA in predicting mortality in critically ill patients, we aimed to evaluate the benefit of adding PANDORA to the Global Leadership Initiative on Malnutrition (GLIM) for mortality prediction in the ICU setting by comparing it with the other valid mortality predictors.

Article Synopsis
  • Handgrip strength (HGS) is crucial for assessing overall health and aging, and significant differences between dominant and non-dominant hand strength may indicate impaired muscle function.
  • A study involving 512 older adults revealed that 51.6% had handgrip asymmetry, with 57.6% living with frailty; those with asymmetric and low HGS had a threefold increased risk of frailty.
  • The findings suggest that measuring handgrip asymmetry could be a valuable tool for clinicians in identifying frailty among older patients.

Background: Proponents argue that a high waist-to-calf ratio (WCR) may indicate an imbalance between muscle and fat in the body, making it a potential predictor for sarcopenic obesity (SO). The WCR is a new index incorporating both measurements, providing a reliable approach for assessing the imbalance between abdominal fat and leg muscle mass. The present study aimed to examine the association of WCR with SO and reveal the predictive effect of SO in community-dwelling older adults.

Background: Changed body composition with increased fat content and decreased muscle mass is seen in renal transplantation recipients (RTRs). Increased fat mass might mask underlying muscle mass loss; measuring low body mass index and weight reduction alone may not be sensitive enough to diagnose malnutrition in RTRs. We aimed to determine the prevalence of malnutrition in stable RTRs using the Global Leadership Initiative on Malnutrition (GLIM) criteria and to assess the use of muscle ultrasonography (US) to compare the performance of various muscle US measurements in the diagnosis of reduced muscle mass.

Background: Frailty is an important geriatric syndrome that can be seen as a way of recognizing and distinguishing the complex health conditions of older people. Due to the time limitation, short and simple instruments are most feasible in clinical practice, and several quick screening tools have been developed and validated, Groningen frailty indicator (GFI) is one of these scales. We aimed to validate and evaluate the reliability of the GFI in outpatient older adults in the Turkish population.

Introduction: Physical phenotype and the cumulative deficit model are two well-known concepts of frailty. One of the main components of frailty is loss of muscle mass and function, which may also include swallowing muscles, therefore is a risk factor for dysphagia. Since dysphagia is seen starting from the early stages of Alzheimer's Disease (AD), in this study we aimed to reveal the relationship between frailty and dysphagia and dysphagia-related quality of life through Swallow Quality of Life (SwalQoL) tool in patients with AD and compare them with cognitively intact older adults.
