Prevalence of Unmet Service Needs and Associated Person-Reported Outcomes in Long-Term Services and Supports in the United States

9 hours 6 minutes ago
CONCLUSIONS: Consumer-reported unmet LTSS needs are frequent, vary greatly across care settings and funding programs, and are associated with poorer QoL-related outcomes; highlighting substantial system-level gaps in the fragmented LTSS landscape and the need for coordinated investments and structural reforms to better meet the needs of individuals relying on these services.

Epigenetic Gene Networks Governing Immune State Transitions Across the Lifespan

9 hours 6 minutes ago
Immune function across development, tissue repair, aging, and disease depends not only on signaling pathways but also on epigenetic architectures that determine whether coordinated transcriptional programs can be accessed and resolved. Increasing evidence indicates that epigenetic gene networks regulate the accessibility and reversibility of semi-stable immune states, shaping plastic, homeostatic, reparative, and degenerative configurations. We propose the concept of epigenetic transition...

Amino acid and appendicular skeletal muscle mass insufficiency are associated to cognitive decline in Chinese population

9 hours 6 minutes ago
The relation between cognitive impairment and skeletal muscle mass or physical exercise has been broadly discussed. However, the underlying molecular features have not been systemically investigated. Essential amino acids are the key factors for skeletal muscle mass. In the current study, we investigated the abundance of metabolites in the serum of ~ 1500 participants in various cognitive status from multiple centers. Our study revealed a positive correlation between serum level of essential AA...

Dysregulation of a novel autophagosome-mitochondria contact contributes to tauopathy-related neurodegeneration by disrupting autophagy

9 hours 6 minutes ago
Beyond their role in energy production, mitochondria also interact with other organelles through forming membrane contacts that serve as central hubs of cellular metabolism and signaling. Aberrant mitochondria-organelle communication has been implicated in various neurodegenerative diseases, but the underlying mechanisms and their pathological consequences remain poorly understood. Here, we reveal that tauopathy synapses exhibit excessive tethering of autophagosome/autophagic vacuole...

Artificial intelligence in geriatric healthcare: a scoping review

9 hours 6 minutes ago
CONCLUSIONS: Artificial intelligence holds significant promise for mitigating the global geriatric healthcare crisis exacerbated by demographic aging and nursing shortages. However, realizing its full potential requires a coordinated, multi-stakeholder approach to overcome the entrenched systemic, human, and social obstacles. The proposed roadmaps provide an actionable framework that may facilitate the development of artificial intelligence systems that are more efficient, equitable, and...

Near-gaze fixation promotes use of spin turns during walking: age-independent visuomotor effects with maladaptive behavioral consequences in older adults

9 hours 6 minutes ago
CONCLUSION: These findings identify gaze fixation as a key determinant of increased spin-turn use during turning in older adults, whereby constraining gaze to the near walking surface alters visual information available for step planning and promotes maladaptive turning strategy selection.

Scientists May Have Found What Really Triggers Alzheimer’s Disease

16 hours 16 minutes ago
Scientists may have uncovered a hidden trigger behind Alzheimer’s disease. Instead of plaques being the root cause, amyloid beta appears to interfere with tau, a protein that helps keep neurons functioning properly. This disruption could set off the damage that eventually leads to the disease’s most recognizable brain changes.

Ancient DNA reveals plague was already killing humans 5,500 years ago

1 day 6 hours ago
Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks. By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbreaks that wiped out many children and young teenagers.

Mechanisms and interventions of epigenetic aging

1 day 9 hours ago
Increasing evidence suggests that epigenetic dysregulation is both a hallmark and a potential driving force of aging. As a multifactorial, non-linear, and systemic biological process, aging likely results from a progressive imbalance in a complex epigenetic network involving DNA, histones, RNA, and non-coding sequences. These interconnected alterations collectively lead to core aging features such as genomic instability, heightened inflammation, and loss of cellular identity. In this review, we...
