Aging & Longevity

CONCLUSION: The time spent caring for people living with cancer by informal carers is significant. Recognizing and rigorously investigating the role of informal cancer carers in reducing the burden on the formal care sector and improving the quality of life of people living with cancer is essential to understanding the impact and significance of caring, which will facilitate impactful policy changes.

Ageing is associated with neuroimmune shifts from a resting to a hyperactive and inflammatory state, termed 'Neuroinflammageing', attributed to microglial priming, hyperactive astrocytes, cytokine and chemokine release, blood brain barrier leakage, and infiltration of peripheral immune cells. This special issue of Biogerontology on 'Neuroimmunology in Ageing and Longevity' brings together 11 reviews and original research papers dealing with the complex cross-talk between CNS and peripheral...

CONCLUSIONS: Our findings highlight the importance of choosing an incentive adjusted to the performance outcome when designing studies that examine the influence of incentives or practice on prospective memory.

CONCLUSIONS: Reduced brain lymphatic function (lower ALPS index) is associated with cognitive decline in postmenopausal women, and this relationship is mediated by estrogen levels. The DTI-ALPS index may serve as a novel biomarker for menopause-related cognitive health.

Aging heterogeneity in tissue-regenerative cells leads to variable therapeutic outcomes, complicating quality control and clinical predictability. Conventional analytical methods relying on labeling or cell lysis are destructive and incompatible with downstream therapeutic applications. Here we show a label-free, nondestructive single-cell analysis platform based on nanosensor chemical cytometry (NCC), integrated with automated hardware and deep learning. nIR fluorescent single-walled carbon...

Psilocybin, the naturally occurring psychedelic compound produced by hallucinogenic mushrooms, has received attention due to considerable clinical evidence for its therapeutic potential to treat various psychiatric and neurodegenerative indications. However, the underlying molecular mechanisms remain enigmatic, and few studies have explored its systemic impacts. We provide the first experimental evidence that psilocin (the active metabolite of psilocybin) treatment extends cellular lifespan and...

Cell cycle regulation, aging, and metabolism are pivotal biological processes linked to both normal physiology and disease development. Understanding their interplay is crucial for advancing gerontological research and clinical oncology. We analyzed articles and reviews on the cell cycle, aging, and metabolism from 2004 to 2023 using the Web of Science Core Collection. Bibliometric tools, VOSviewer, and CiteSpace, were applied to visualize collaboration networks, geographic distributions, and...

CONCLUSIONS: Older adults' experiences of existential group treatment suggest that engaging in existential dimensions of aging can be helpful when done in a structured setting together with others. Reduced experiential avoidance, increased determination to do what feels meaningful, relational aspects as well as one's own commitment to therapy can help explain how existential group treatment may contribute to change among older adults with psychological distress.

CONCLUSION: The study underscores the importance of considering both direct and indirect effects in understanding the pathways through which early life experiences influence nutritional status in old age. The unexpected finding regarding the direct effect of childhood conditions on overweight in the Indian context raises important questions about the complexities of nutrition and health in this population.

BACKGROUND: Ageing is a heterogeneous process, which is associated with heterogeneous resilience in older people. Cancer surgery and treatment may be associated with accelerated ageing in some older people; studying this process will improve understanding to enable treatments to prevent adverse effects on physical and cognitive function.

CONCLUSIONS: Studies have shown that the social participation and sleep quality of older people in China can mediate the connection between urinary incontinence and subjective well-being. Therefore, it is necessary to pay timely attention to and intervene in the social participation and sleep quality of older patients with urinary incontinence to improve their subjective well-being.

Platelet-derived growth factors can restore the proliferative potential of senescent cells taken from the degenerated intervertebral discs of aged humans.

As the European Union undergoes a demographic shift toward an aging population, the rising prevalence of age-related diseases poses significant public health challenges. Across the EU, disparities in health indicators and life expectancies highlight the urgency of addressing factors that contribute to unhealthy aging. Burnout, characterized by emotional, physical, and mental exhaustion, has emerged as a critical determinant of healthy aging, with profound biological, psychological, and social...

Individual imaging and fluid biomarkers provide insights into specific components of brain health, but integrated multimodal approaches are necessary to capture the complex, interrelated biological systems that contribute to brain homeostasis and neurodegenerative disease. Using data from the Brain and Cognitive Health (BACH) cohort study (N = 127; mean age = 67 years, 68% women), we performed an exploratory factor analysis to identify latent constructs of brain health. We included multimodal...

The neuromuscular junction (NMJ) is a vital interface between motor neurons and muscle fibers, and alterations in its structure and function can substantially influence the onset and progression of sarcopenia. Electromyography (EMG) is a critical tool to assess motor unit and NMJ function, providing insights into neuromuscular activation patterns and the integrity of motor unit communication. However, its implications for aging and muscle performance during sarcopenia have not been fully...

Microglia-mediated neuroinflammation has been shown to exert an important effect on the progression of a growing number of neurodegenerative disorders. Prolonged exposure to detrimental stimuli leads to a state of progressive activation and aging-related features in microglia (also termed as senescent microglia). However, the mechanisms by which senescent microglia contribute to neuroinflammation-induced cognitive dysfunction remain to be elucidated. Here, we developed a mouse model of...

Tai Chi practice has been widely adopted to improve balance and prevent falls in older adults. However, the neural mechanisms underlying the benefits of Tai Chi are difficult to evaluate during traditional balance assessments. The goal of this study was to evaluate the effects of Tai Chi and healthy aging on corticomuscular coherence (CMC) while standing in virtual balance-demanding environments. We recorded neural, muscular, and behavioral data in an immersive virtual reality environment while...
