CONCLUSION: Oral and gut microbiota diversity showed significant differences between patients with recurrent pneumonia and common pneumonia pneumonia-infected patients. The higher prevalence of both S. aureus and K. pneumoniae in the oral microbiota offers crucial insights into the pneumonia etiology. Specifically, the increased abundance of K. pneumoniae may contribute significantly to the heightened lung infections susceptibility among elderly individuals.

CONCLUSIONS: In elderly patients, long-term (current) aspirin use is negatively associated with the incidence of SAD and is also linked to improved clinical outcomes.

Aging is increasingly understood not as the passive accumulation of molecular damage, but as the cumulative cost of unresolved physiological adaptation under bioenergetic constraint. This review introduces Exposure-Related Malnutrition (ERM) as a mechanistically grounded and clinically actionable phenotype of early maladaptation. ERM arises from sustained metabolic strain during chronic stress exposure and manifests not through overt weight loss or nutrient deficiency, but through subtle,...

Cytoskeleton-Associated Protein 4 (CKAP4) is a multifunctional protein implicated in diverse cellular processes, including cytoskeletal organization, signal transduction, and extracellular matrix remodeling. Recent studies have highlighted the dual role of CKAP4 in regulating cell growth and aging. On one hand, CKAP4 can promote cell proliferation and survival by activating signaling pathways such as PI3K/Akt, thereby delaying cellular senescence under physiological conditions. On the other...

Aging-related frailty increases the risk of falls, disability, and mortality. Frailty is linked to abnormalities in whole-body metabolism. However, the causal relationship between circulating metabolic traits and frailty remains unclear. This study aims to clarify the causal effects of circulating metabolites on frailty. We used bidirectional two sample and multivariable Mendelian Randomization (MVMR) methods to assess associations between circulating metabolites and the Frailty Index (FI)....

Brain health is increasingly recognized as a critical component of overall wellbeing, particularly concerning neurodegenerative diseases, which are characterized by the progressive degeneration of the nervous system. Conditions such as Alzheimer's disease (AD) and Parkinson's disease, together with less common disorders, resembling Amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), significantly impact cognitive and physical health, affecting over 50 million individuals...

AIM: To investigate the dynamics of neuromotor functions from 6 to 80 years with the Zurich Neuromotor Assessment (ZNA) and to provide reference curves for clinical and research use.
