Lactate Secretion by Monocytes as a Determinant of Innate Immune Cell Fitness in Healthy Elderly
Immune cell metabolism is increasingly recognized as an important regulator of immune function, but its role in age-related immune dysfunction, chronic inflammation, and cardiometabolic complications in humans remains incompletely understood. This study investigated the impact of aging on monocyte metabolic and functional signatures in a healthy elderly population. We aimed to leverage these immunometabolic signatures to identify healthy elderly individuals with reduced immune cell fitness and,...

Analysis of EEG coherence according to the onset of Alzheimer's disease
Alzheimer's disease (AD) is one of the most common neurodegenerative diseases, the effects of which can be slowed down by an early and correct diagnosis. Greater diagnostic accuracy depends on a better understanding of the disease. In this regard, electroencephalography is a promising low-cost tool to explore brain activity and support the diagnosis of AD. When analyzing EEG signals, age is a factor that is not usually taken into account despite being one of the main risk factors. In this work,...
Anti-amyloid monoclonal antibody therapies in Alzheimer's disease - a scoping review
Alzheimer's disease (AD) is a progressive neurodegenerative disorder affecting millions worldwide, and with advancements in the medical field, Anti-amyloid monoclonal antibodies (AA mAbs) targeting amyloid-β have emerged as potential disease-modifying agents altering AD pathology. This scoping review mapped the characteristics, patterns, and gaps in clinical trials investigating the efficacy and safety of AA mAbs in AD treatments, with focus on cognitive, functional, biochemical, imaging, and...
Identification of circular RNAs associated with ageing of the dorsolateral prefrontal cortex across the adult lifespan
Circular RNAs (circRNAs) are emerging as crucial regulators of biological processes and have been implicated in age-related diseases. Few studies have explored age-related circRNA expression in the human brain across the adult lifespan. This study aims to identify age-related differentially expressed circRNAs in human post-mortem dorsolateral prefrontal cortex (DLPFC) samples, a region critically involved in cognition that exhibits early signs of age-related changes. Total RNA sequencing was...
The Level of Technophobia Among Older Adults in China in the Context of Digital Health: A Systematic Review and Meta-Analysis
CONCLUSIONS AND IMPLICATIONS: In China, technophobia among older adults is moderate, particularly concerning privacy concerns dimensions. Higher technophobia levels are observed in those who are older, have lower education and income, and live in rural areas. This trend is global amid aging and digitalization. Health care professionals and policymakers should identify high-risk groups and risk factors, developing targeted interventions through multidisciplinary collaboration to reduce...
