Enhancing quality of life for activity-limited older adults in Sri Lanka: a need-based caregiver education intervention study
CONCLUSIONS: The need-based educational intervention, along with the educational handbook, has a positive impact on the QoL of older adults. We recommend formal educational sessions with country-specific guidelines for caregivers of activity-limited older adults in the community to improve their QoL.
Comparison of the efficacy of laparoscopic primary closure of the common bile duct and T-tube drainage in the treatment of choledocholithiasis in elderly patients
CONCLUSION: Laparoscopic primary suture of the common bile duct avoids some complications associated with T-tube drainage and offers advantages such as less trauma, faster recovery, and shorter hospital stay. For elderly patients with clear indications, this surgical method is a safe and feasible option.
Association of health promotion behaviors with frailty in Chinese middle-aged and older adults: a cross-sectional study
CONCLUSION: Multidimensional health promotion behaviors are critical factors in the frailty status of Chinese middle-aged and older adults, and there are gender differences in the age-dependent trends in the levels of health promotion behaviors among them with different frailty states. This informs the provision of targeted prevention and intervention services for middle-aged and older adults.
Optimal exercise interventions for enhancing cognitive function in older adults: a network meta-analysis
Background: Cognitive decline poses a significant challenge to healthy aging. While exercise is widely recognized for its cognitive benefits, the comparative efficacy of different exercise modalities and optimal intervention protocols for specific cognitive domains in older adults remains unclear. Objective: This network meta-analysis aimed to systematically compare the effects of five exercise modalities-resistance training, aerobic exercise, mind-body exercise, multicomponent exercise, and...
Association between dynapenic abdominal obesity and mild cognitive impairment among middle-aged and older community-dwelling adults
CONCLUSIONS: Among community-dwellers in six LMICs, DAO was significantly associated with MCI among middle-aged individuals, but not among older people. However, it is important to note that the study was cross-sectional in nature, and thus, it is not known whether DAO leads to MCI or vice versa. Therefore, future longitudinal studies are necessary to clarify temporal associations and possible causality.
Ultra-processed foods, biological ageing, and all-cause mortality risk: a prospective cohort study using 172,225 participants from UK Biobank
Ultra-processed foods (UPF) are increasingly linked to negative health outcomes, including chronic diseases and mortality. Recent evidence suggests that UPF may accelerate biological ageing, potentially explaining their harmful effects. Therefore, this study was aimed to investigate associations between UPF intake categories and mortality risk, examining biological ageing's mediating and modifying effects. We used a prospective cohort design including 172,225 participants in the UK Biobank who...
Cellular senescence-from solid organs to vascularized composite allotransplants
Vascularized composite allotransplantation (VCA) has emerged as a novel therapy approach to restore form and function in patients with severe tissue defects of the face, hand, and abdominal wall, among other anatomical regions. The composite allografts comprise different tissues such as skin, muscle, or bone. Clinical data demonstrate promising mid- and long-term outcomes following VCA surgery, but our understanding of the cellular interactions and molecular pathways in VCA surgery is oftentimes...
Weight of time: exploring the link between obesity and aging
Obesity and aging are interrelated public health concerns, with growing prevalence, especially as global demographics shift toward an older population. This narrative review explores the mechanisms through which obesity accelerates the aging process, focusing on major aging pathways affected by obesity, including deregulated nutrient sensing, telomeres attrition, epigenetic alterations, mitochondrial dysfunction, stem cell exhaustion, and altered intercellular communication. Evidence suggests...
Larval diapause slows adult epigenetic aging in an insect model, Nasonia vitripennis
Epigenetic clocks based on DNA methylation provide robust biomarkers of biological age, yet the mechanistic basis and functional significance of slowing these clocks remain unclear. Progress has been limited by the lack of short-lived, genetically tractable model organisms with functional DNA methylation systems. The jewel wasp, Nasonia vitripennis, offers a unique solution. It combines a functional DNA methylation system with a short lifespan and established tools for experimental manipulation....
SARS-CoV-2 uptake and inflammatory response in senescent endothelial cells are regulated by the BSG/VEGFR2 pathway
Aging is a risk factor for severe COVID-19, characterized by vascular endothelial dysfunction. Although possible susceptibility of vascular endothelial cells (ECs) to SARS-CoV-2 infection has been suggested, the details of entry into cells have not been clarified. Previously, we reported that in an aged mouse model of severe COVID-19, ECs show a massive viral uptake and inflammatory response. Here, we focused on the endocytic capacity of senescent ECs. We found that the senescent ECs showed high...
Reinstating memories' temporal context at encoding causes Sisyphus-like memory rejuvenation
As memories age, their immediate retrievability decreases albeit, due to ongoing memory consolidation, their future rate of forgetting weakens. Here, we show in two experiments (N = 1.216 participants) that mentally traveling back in time to older memories' temporal context at encoding reverses the two effects and makes the memories similar again to how they were at an earlier point in time. Mental time travel increased both the memories' immediate retrievability and their future rate of...
