Aging produces numerous physical and physiologic changes, which in turn alter nutritional requirements and affect nutritional status. The presence of chronic disease, and/or medications can enhance potential disparities between nutrient needs and dietary intake, leading to malnutrition. Indeed, research suggests that malnutrition is a common condition among the elderly. Therefore, regular nutritional assessment should be done as an integral part of healthcare for elderly. Also, it is important to take in consideration all determinants of geroanthropometry. The physiologic changes associated with aging affect requirement for several essential nutrients. In general, the requirement for many nutrients decreases, concomitant with the decrease in energy needs. However, some nutrients are needed in higher amounts. Additionally, various psychosocial and socioeconomic changes that often attend aging may also alter dietary intake. Dietary planning is important part of nutritional care in the elderly. Also, some elderly persons can benefit with dietary supplements and oral nutritional supplements (enteral formulas) which can be prescribed by diagnosed or threatening malnutrition. Croatian guidelines for nutrition in the elderly have been developed by interdisciplinary expert group of Croatian clinicians, gerontologists, anthropologists, nutritionists and other professionals involved with care for elderly population. The guidelines are based on evidence from relevant medical literature and clinical experience of working group.

A participatory needs assessment to map the system dynamics of overweight related behaviours of 10-14-year-old adolescents living in an underserved neighbourhood in Amsterdam, the Netherlands.
BMC Public Health
January 2025
Amsterdam UMC location Vrije Universiteit Amsterdam, Public and Occupational Health, De Boelelaan 1117, Amsterdam, the Netherlands.
Background: Developing interventions along with the population of interest using systems thinking is a promising method to address the underlying system dynamics of overweight. The purpose of this study is twofold: to gain insight into the perspectives of adolescents regarding: (1) the system dynamics of energy balance-related behaviours (EBRBs) (physical activity, screen use, sleep behaviour and dietary behaviour); and (2) underlying mechanisms and overarching drivers of unhealthy EBRBs.
Methods: We conducted Participatory Action Research (PAR) to map the system dynamics of EBRBs together with adolescents aged 10-14 years old living in a lower socioeconomic, ethnically diverse neighbourhood in Amsterdam East, the Netherlands.

Department of Neonatology, Children's Hospital of Soochow University, Suzhou, China.
This study investigated the correlation between quantitative echocardiographic characteristics within 3 days of birth and necrotizing enterocolitis (NEC) and its severity in preterm infants. A retrospective study was conducted on 168 preterm infants with a gestational age of < 34 weeks. Patients were categorized into NEC and non-NEC groups.

Background & Aims: Current guidelines recommend a 2-step approach for risk stratification in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) with Fibrosis-4 index (FIB-4) followed by liver stiffness measurement (LSM) by vibration-controlled transient elastography (VCTE) or similar second-line tests. This study aimed to examine to prognostic performance of this approach.
Methods: The VCTE-Prognosis Study was a longitudinal study of patients with MASLD who had undergone VCTE examinations at 16 centres from the US, Europe and Asia with subsequent follow-up for clinical events.
The Role of Nutrition and Nutritional Supplements in the Prevention and Treatment of Malnutrition in Chronic Obstructive Pulmonary Disease: Current Approaches in Nutrition Therapy.
Curr Nutr Rep
January 2025
Faculty of Health Sciences, Department of Nutrition and Dietetics, Hacettepe University, Ankara, Turkey.
Purpose Of Review: Malnutrition is a significant comorbidity in Chronic Obstructive Pulmonary Disease (COPD), contributing to disease progression and reduced quality of life. This narrative review examines the role of nutritional therapy in the prevention and management of malnutrition in COPD, emphasizing evidence-based approaches and their clinical implications.
Recent Findings: COPD patients face increased metabolic demands, systemic inflammation, and reduced dietary intake, resulting in muscle wasting, sarcopenia, and cachexia.
