Here we examined how four dietary patterns relate to 15-year multimorbidity accumulation in 2,473 community-dwelling older adults from the Swedish SNAC-K cohort. Multimorbidity was operationalized as the total number of chronic conditions and grouped into three organ systems. Higher adherence to the Mediterranean-DASH Diet Intervention for Neurodegenerative Delay, the Alternative Healthy Eating Index and the Alternative Mediterranean Diet was inversely associated with the annual rate of total chronic disease accumulation (β coefficient (95% confidence interval) per 1-s.d. increment: −0.049 (−0.065 to −0.032), −0.051 (−0.068 to −0.035) and −0.031 (−0.048 to −0.014), respectively), whereas higher adherence to the Empirical Dietary Inflammatory Index was associated with a faster rate of accumulation (0.053 (0.035–0.071)). Similar associations were observed for cardiovascular and neuropsychiatric diseases but not for musculoskeletal diseases. Some associations varied by sex and age. Our findings support diet quality as a modifiable risk factor for multimorbidity progression in older adults, with possible implications for dietary guidelines, public health strategies and clinical practice. In a Swedish cohort, Abbad-Gomez et al. report that diet quality is inversely associated with the rate of accumulation of total, cardiovascular and neuropsychiatric chronic diseases in older adults, supporting diet quality as a modifiable risk factor for multimorbidity progression.","PeriodicalId":94150,"journal":{"name":"Nature aging","volume":"5 8","pages":"1481-1490"},"PeriodicalIF":19.4,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12350159/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144736444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we adapted a previously published dynamic Markov microsimulation model, the Future Elderly Model, to estimate disease trajectories and healthcare expenditure among adults aged 51 years and older in Singapore. The model simulated four long-term lifestyle interventions aligned with the Healthier SG program from 2020 to 2050. Our projections indicate an increasing prevalence of chronic conditions, comorbidities, obesity and disabilities, with ethnic differences. The projected lifetime healthcare expenditure is the highest among Indians (US $93,900; 95% credible interval (CI), US $68,900–119,000), followed by the Chinese (US $75,700; 95% CI, US $57,600–93,800) and Malays (US $70,000; 95% CI, US $52,000–88,000). Despite having a higher chronic disease burden, Malays are expected to incur lower lifetime expenditure due to their shorter life expectancy. Implementing all 4 interventions could save US $505 million (95% CI, US $462–547 million) in healthcare use by 2050. Sustained lifestyle interventions may moderate the increase in future burdens. Policy strategies should prioritize preventive care tailored to the specific needs of diverse population subgroups. Population aging presents challenges for healthcare and social care systems in ensuring that services are available for older adults. Here the authors performed a Singapore-based simulation study that projects rising chronic disease prevalence and healthcare costs, showing that long-term lifestyle interventions can moderate the increase in future diseases and healthcare spending by 2050.","PeriodicalId":94150,"journal":{"name":"Nature aging","volume":"5 7","pages":"1358-1369"},"PeriodicalIF":19.4,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12270899/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144644462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stem cell-derived extracellular vesicles (EVs) are emerging as potential therapeutic candidates that can mediate donor cells’ beneficial effects. Here, we tested the effects of ABPC-derived EVs (EVsABPC) on aging in mice and rhesus macaques (Macaca mulatta). We identified a variety of unique factors in EVsABPC and showed that in vitro, EVsABPC attenuated phenotypes of senescence in bone marrow stem cells. In aged mice and macaques, EVsABPC substantially increased femoral bone mineral density. Further, intravenous EVsABPC improved physical performance, enhanced cognitive function and reduced systemic inflammation in aged mice, while reversing epigenetic age by over 3 months. In macaques, EVABPC treatment was also neuroprotective, reduced inflammation, improved locomotor function and reduced epigenetic age by over 2 years. Our findings position ABPCs as an emerging and practical source of EVs with translational value for healthy aging interventions.

To investigate systematically the heterogeneity of senescent vascular cells in atherosclerosis, we used a high-fat diet and PCSK9 overexpression to induce atherosclerosis in a senescence reporter mouse model (p16-tdTomato+/−) and performed single-cell RNA sequencing on whole aortas. Using the SenMayo and CellAge gene sets, we identified four clusters of vascular smooth muscle cells (VSMCs), fibroblasts and T cells enriched in features of senescence, which were reduced upon treatment with the senolytic agent ABT-737. We then derived a global senescence signature of atherosclerosis including Spp1, Ctsb and Tnfrsf11b mRNAs. We validated the enrichment of these mRNAs in senescence by using spatial transcriptomics in a second mouse model of atherosclerosis and senolysis (Ldlr−/−; p16-3MR), as well as by analyzing in vitro models of human VSMC senescence. Our results uncover a vascular-specific transcriptomic signature of senescence that may be exploited for tracking and treating age-related vascular diseases.

However, the induction, regulation and physiological role of secondary senescence in vivo remain largely unclear. Here we generated senescence-inducible mouse models expressing either the constitutively active form of MEK1 or MKK6 and mCherry, to map primary and secondary senescent cells. Our models recapitulate characteristic features of senescence and demonstrate that primary and secondary phenotypes are highly tissue- and inducer-dependent. Spatially resolved RNA expression analyses at the single-cell level reveal that each senescence induction results in a unique transcriptional profile—even within cells of the same cell type—explaining the heterogeneity of senescent cells in vivo. Furthermore, we show that interleukin-1β, primarily derived from macrophages, induces secondary phenotypes. Our findings provide insight into secondary senescence in vivo and useful tools for understanding and manipulating senescence during aging. Through non-cell-autonomous functions, senescent cells can induce secondary senescence in bystander cells.
