Article Abstract
Introduction: Sarcopenia, with its complex diagnostic process, is a likely independent predictor of poor prognosis in patients with Alzheimer's disease (AD). However, research on the clinical characteristics and biomarkers of AD patients with sarcopenia (ADSA) is limited.
Methods: This study included 180 ADSA and 188 AD patients without sarcopenia (ADNSA), and evaluated demographics, cognitive function, motor capacity, emotional state, and daily living abilities.
Results: ADSA patients were older, with worse motor and cognitive functions, more severe depression, poorer social functioning, and lower daily living abilities compared to ADNSA patients. Multivariate regression identified age, low Frailty Rating Scale (FRS) scores, low serum albumin level, and low creatinine/cystatin C ratio (CCR) as risk factors for sarcopenia. A nomogram model based on these indicators demonstrated high discriminative power and clinical utility.
Discussion: Sarcopenia significantly affects AD patients' various functions. The nomogram model aids in the early detection of and personalized interventions for sarcopenia in AD.
Highlights: Sarcopenia is a risk factor for Alzheimer's disease (AD), and the coexistence of sarcopenia affects various functions and quality of life in patients with AD. Serum albumin and Frailty Rating Scale (FRS) scores are significantly associated with both sarcopenia and cognitive assessment indicators in AD patients with sarcopenia (ADSA). The combined sarcopenia nomogram model with indexes of age at diagnosis, creatinine/cystatin C ratio (CCR), FRS score, and albumin levels can aid in effectively identifying and personalizing interventions for sarcopenia in the AD population.

From Gut Inflammation to Cardiovascular Conflagration: Mapping IBD's Cardiometabolic Risks.
Curr Atheroscler Rep
September 2025
Division of Gastroenterology and Hepatology, Lynda K. and David M. Underwood Center for Digestive Health, Houston Methodist Hospital, Houston, TX, USA.
Purpose Of Review: This review aims to characterize the known cardiovascular (CV) manifestations associated with inflammatory bowel disease (IBD) and the underlying mechanisms driving these associations.
Recent Findings: Gut dysbiosis, a hallmark of patients with IBD, can result in both local and systemic inflammation, thereby potentially increasing the risk of cardiovascular disease (CVD) in the IBD population. Micronutrient deficiencies, anemia, and sarcopenia independently increase the risk of CVD and are frequent comorbidities of patients with IBD.
Effects of Combined Exercise Training on Modulating Fine Particulate Matter-Induced Skeletal Muscle Damage in Offspring Gestationally Exposed.
J Cachexia Sarcopenia Muscle
October 2025
Department of Sports Science, College of Natural Science, Jeonbuk National University, Jeonju, Republic of Korea.
Background: Fine particulate matter has developmental toxicity, and midgestation is an important period for the development of foetal skeletal muscle. The ability of exercise to modulate skeletal muscle damage in mice exposed to PM during gestation remains unclear.
Methods: Pregnant C57BL/6 mice were exposed to 50 μg/m PM for 2 h on five consecutive days starting at embryonic day 12.
Nutritional status, immunonutrition, and gut microbiome: a coming of age for immunotherapy?

In the last decades, immunotherapy has revolutionized cancer treatment. Despite its success, a significant number of patients fail to respond, and the underlying causes of ineffectiveness remain poorly understood. Factors such as nutritional status and body composition are emerging as key predictors of immunotherapy outcomes.

Study Design: Systematic review.
Purpose: As the number of elderly increases, age-related changes of body composition like osteoporosis and sarcopenic muscle changes contribute to higher morbidity, less quality of life and higher health care costs. Data on the effect of muscle atrophy on osteoporotic vertebral fractures is limited.
Utilizing the Timed Up and Go Test to Predict Five-Year Mortalities Among Older Cardiovascular Inpatients: A Prospective Cohort Study.
Rev Cardiovasc Med
August 2025
Department of Cardiology, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, 100730 Beijing, China.
Background: To examine the predictive value of the Timed Up and Go test (TUGT) for five-year mortality among older patients with cardiovascular disease (CVD).
Methods: This prospective cohort study was conducted at the Beijing Hospital in China from September 2018 to April 2019, with a follow-up period of 5 years. Patients underwent the TUGT at baseline and were categorized into two groups based on the subsequent results: Group 1 (TUGT >15 s) and Group 2 (TUGT ≤15 s).
