Background & Aims: Physical frailty may compromise physical function and reduce self-reliance in community-dwelling older adults. We investigated if nutritional risk factors and protein intake were associated with physical frailty in community-dwelling adults.
Methods: This cross-sectional study combined data from two studies in community-dwelling adults ≥65 years. Variables included physical frailty (SHARE-FI75+), nutritional risk factors (dysphagia, poor dental status, illness, unintentional weight loss, low and high BMI), chronic diseases, physical function, and protein intake (4-day food records). Logistic regression analyses were performed to investigate the association between physical frailty, number of nutritional risk factors and specific nutritional risk factors, and between physical frailty and protein intake.
Results: A total of 1430 participants were included in the study of these n = 860 were ≥80 years. Having one, two or more nutritional risk factors increased odds of physical pre-frail/frail condition (adjusted OR 1.39 95% CI 1.07-1.80; OR 2.67 1.76-4.04, respectively). Unintentional weight loss, poor dental status, dysphagia, and high BMI independently increased odds of physical pre-frail/frail condition. In participants ≥80 years two or more nutritional risk factors were associated with physical pre-frail/frail condition (adjusted OR 2.56 95%CI 1.45-4.52) and high BMI increased odds of physical pre-frail/frail condition independently. Higher intakes of protein did not significantly reduce odds of physical pre-frail/frail condition (adjusted OR 0.23 95% CI 0.05-1.09) in this sample of community-dwelling adults ≥80 years.
Conclusion: Nutritional risk factors were independently associated with physical pre-frail/frail condition in community-dwelling older adults. Tackling nutritional risk factors offers an opportunity in primary prevention of malnutrition and physical frailty.

Association of Geriatric Nutritional Risk Index Scores with Outcomes in Patients Undergoing Maintenance Hemodialysis.

The Geriatric Nutritional Risk Index (GNRI) is an effective tool for identifying malnutrition, and helps monitor the prognosis of patients undergoing maintenance hemodialysis. However, the association between the GNRI and cardiovascular or all-cause mortality in hemodialysis patients remains unclear. Therefore, this study investigated the correlation of the GNRI with all-cause and cardiovascular mortality in patients undergoing maintenance hemodialysis.

Background/objectives: Water-soluble vitamins, comprising the B-complex vitamins and vitamin C, are essential for normal growth, cellular metabolism, and immune function in pediatric populations. Due to limited storage in the body, these vitamins require consistent intake to prevent deficiencies. Pediatric populations, particularly infants and young children, face a heightened risk of both deficiency and, in rare cases, toxicity due to varying dietary intake and increased developmental needs.

Background/objectives: Colorectal cancer (CRC) holds the third and second position among cancers affecting men and women, respectively. Frequently, the first-line treatment for metastatic CRC consists of the intravenous administration of 5-fluorouracil and leucovorin in combination with oxaliplatin or irinotecan. Physiologically-based pharmacokinetic models (PBPK) aim to mechanistically incorporate body physiology and drug physicochemical attributes, enabling the description of both systemic and organ drug exposure based on the treatment specificities.

Background/objectives: The DNA methylation of neonatal cord blood can be used to accurately estimate gestational age. This is known as epigenetic gestational age. The greater the difference between epigenetic and chronological gestational age, the greater the association with an inappropriate perinatal fetal environment and development.
