Article Abstract
Background: Body composition alterations are frequent in patients with cancer or chronic liver disease, but their prognostic value remains unclear in many cancer entities.
Objective: We investigated the impact of disease aetiology and body composition after surgery for intrahepatic cholangiocarcinoma (iCCA), a rare and understudied cancer entity in European and North American cohorts.
Methods: Computer tomography-based assessment of body composition at the level of the third lumbar vertebra was performed in 173 patients undergoing curative-intent liver resection for iCCA at the Department of Surgery, Charité - Universitätsmedizin Berlin. Muscle mass and -composition as well as subcutaneous and visceral adipose tissue quantity were determined semi-automatically. (Secondary) sarcopenia, sarcopenic obesity, myosteatosis, visceral and subcutaneous obesity were correlated to clinicopathological data.
Results: Sarcopenia was associated with post-operative morbidity (intraoperative transfusions [p = 0.027], Clavien-Dindo ≥ IIIb complications [p = 0.030], post-operative comprehensive complication index, CCI [p < 0.001]). Inferior overall survival was noted in patients with myosteatosis (33 vs. 23 months, p = 0.020). Fifty-eight patients (34%) had metabolic (dysfunction)-associated fatty liver disease (MAFLD) and had a significantly higher incidence of sarcopenic (p = 0.006), visceral (p < 0.001) and subcutaneous obesity (p < 0.001). Patients with MAFLD had longer time-to-recurrence (median: 38 vs. 12 months, p = 0.025, log-rank test). Multivariable cox regression analysis confirmed only clinical, and not body, composition parameters (age > 65, fresh frozen plasma transfusions) as independently prognostic for overall survival.
Conclusion: This study evidenced a high prevalence of MAFLD in iCCA, suggesting its potential contribution to disease aetiology. Alterations of muscle mass and adipose tissue were more frequent in patients with MAFLD.

Department of Cardiology, The First Affiliated Hospital of Soochow University, Suzhou, China.
Objectives: To explore the relationships between cardiac parameters and body composition indices, identifying predictors of subclinical cardiac systolic dysfunction.
Methods: Using anthropometric and serological parameters, echocardiography, and body composition analysis, this study evaluated metabolic profiles, cardiac remodeling patterns, and body composition characteristics in young adult obese patients, while quantifying the correlations between cardiac parameters and body composition indices. Subclinical left ventricular systolic dysfunction was defined as global longitudinal strain (GLS) < 18%.
Associations of adherence to the World Cancer Research Fund lifestyle recommendations with health-related quality of life and fatigue in Adolescent and Young Adult (AYA) cancer survivors: results from the SURVAYA study.

Purpose: Adolescents and young adults (AYAs) with cancer face unique long-term social and health challenges that impact their health-related quality of life (HRQoL). This study explores the association between lifestyle behaviors (physical activity, body composition, and nutrition) and HRQoL as well as fatigue in AYA cancer survivors.
Methods: The cross-sectional SURVAYA study analyzed data from long-term AYA cancer survivors (5-20 years post diagnosis, aged 18-39 at diagnosis) in The Netherlands.

School of Life Sciences, State Key Laboratory of Microbial Technology, Shandong University, Qingdao, 266237 China.
Unlabelled: Mongolian gerbils had high ability to endure both high and cold temperatures. To study the mechanism of high ability for thermal adaptation, gerbils were acclimated to high temperature (30 °C) for 8 weeks, and were measured for metabolic features, body composition as well as mitochondrial content and activities. Lipidomic techniques were used to measure changes in mitochondrial membrane, including potential mitochondrial membrane remodeling during acute thermoregulation in gerbils.

Background: Maternal dietary intervention utilizing complex additives rich in β-carotene has demonstrated the capacity to enhance embryonic intestinal development and influence microbial composition in offspring. Nevertheless, the extended impact of maternal β-carotene inclusion on the intestinal health of post-hatching chicks is still not fully elucidated.
Objective: This research aimed to evaluate the impacts of maternal β-carotene supplementation on the intestinal development and microbial communities in chicks after hatching.
