However, alterations in the blood hydroxymethylome and the potential of 5-hydroxymethylcytosine episignatures as diagnostic biomarkers for PD remain unclear. Methods We employed APOBEC-coupled epigenetic sequencing (ACE-seq) in a two-phase study design. In the first step, we performed single-base resolution profiling of the hydroxymethylome in a small cohort of drug-naïve PD patients and matched controls. Differentially hydroxymethylated regions (DhmRs) were identified and selected for validation. In the second step, these regions were re-sequenced in a larger cohort to develop and evaluate a diagnostic model. Results Initial genome-wide screening identified 16 candidate DhmRs. Although models based solely on these regions yielded modest diagnostic performance, an alternative analysis focusing on differentially hydroxymethylated cytosines within the 16 regions led to a diagnostic panel with robust performance, particularly for early PD detection. Retrospective analyses further confirmed the panel’s ability to distinguish early PD patients from controls. Conclusions Our study provides the first evidence that blood-based hydroxymethylome profiles are promising biomarkers for the early diagnosis of PD.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":"5 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Subjective geriatric complaints as predictors of disability and mortality in community-dwelling older adults: a 5-year cohort study","authors":"Hajime Takechi, Akira Tsuzuki, Hiroshi Yoshino, Takenori Okumura, Yoshikiyo Kanada","doi":"10.1093/ageing/afaf152","DOIUrl":"https://doi.org/10.1093/ageing/afaf152","url":null,"abstract":"Background Various health-related concerns experienced daily by older adults, designated here as subjective geriatric complaints (SGCs), and are suspected to be early signs of the decline in quality of life (QOL). This study aims to test the hypothesis that SGCs are significant predictors of future disability and mortality among older adults. Methods This prospective cohort study was conducted in Japan. A health-related questionnaire was mailed to community-dwelling older adults, and data on the certification of long-term care needs and mortality that occurred over the subsequent 5 years were analysed. The analysis included 10 199 individuals. Thirteen SGCs were classified into six groups. The primary outcome was a composite end point of disability and mortality. Survival time analysis was conducted using Kaplan–Meier analysis and Cox proportional hazard regression models. Results The mean age (standard deviation) of participants (52.4% female) at baseline was 73.7 (6.0) years. Over the 5-year study period, 1793 participants (17.6%) were newly certified as requiring long-term care and 931 (9.1%) died. After adjusting for age, sex, depressive mood, and presence of multimorbidity, the hazard ratios (95% confidence intervals) for SGC 1b (circulatory/respiratory complaints) and SGC 3 (neurological complaints) were 1.558 (1.316–1.884, P < 0.001) and 1.355 (1.14–1.61, P = 0.001), respectively. Conclusion These findings suggest that SGCs are independent risk factors for a decline in QOL. Additionally, risk varied across different symptom groups within SGCs. These differences should be carefully considered in the management of health for older adults.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":"2017 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective To investigate the relationships between glymphatic function and AD-signature region volumes, plasma biomarkers and disease progression in cognitively unimpaired older adults. Methods Two datasets comprising a total of 229 cognitively unimpaired older adults were enrolled. Brain glymphatic function was assessed using diffusion tensor imaging along the perivascular space (DTI-ALPS). The associations between the DTI-ALPS index and volumes in AD-signature regions, including the basal forebrain, entorhinal cortex and hippocampus, were evaluated, along with white matter hyperintensity (WMH) volumes. In dataset 1 with plasma biomarkers, the mediation effects of DTI-ALPS index on plasma biomarkers and cognition were examined. In dataset 2 with follow-up data, the baseline DTI-ALPS index was correlated with the annual percent change in volumes of AD-signature regions and WMH. Results The DTI-ALPS index showed positive correlations with volumes in the basal forebrain, entorhinal cortex and hippocampus, and negative correlations with WMH volumes in both datasets. The DTI-ALPS index negatively associated with plasma phosphorylated tau (ptau) and mediated the relationship between ptau and cognition. The baseline DTI-ALPS index was negatively associated with WMH progression at follow-up. Conclusion Worse glymphatic system function indicates decreased AD-signature region volumes, severe WMH lesions, elevated plasma ptau, and accelerated WMH progression before the occurrence of objective cognitive impairment. Therapeutic methods targeting the glymphatic system may prevent cognitive decline through the clearance of AD pathological proteins and the deceleration of WMH lesions.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":"136 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This can affect individuals’ identity, relationships, and quality-of-life of people with dementia and their relatives. Professional guidelines recommend access to communication intervention, for example through speech and language therapy (SLT) services, but anecdotal evidence suggests that the type and availability of this provision varies. Aims This study aimed to explore the communication needs of people with dementia, their quality-of-life impact, and local and national service provision. Methods This mixed-methods study comprised three phases: Data was analysed using descriptive statistics and thematic analysis. Results Four main themes were identified: dementia-related communication changes; accessing support for communication; identifying communication strategies; and service considerations. The survey identified inconsistent or absent communication input for many people with dementia. Interview and focus group findings highlighted diverse dementia-related communication needs which impacted quality-of-life and support required. Participants suggested service-level considerations for addressing these needs. Conclusion Dementia-related communication impairments are diverse and can considerably impact quality-of-life of people with dementia and their relatives. Communication intervention service-provision varies widely, resulting in unmet needs. These findings add to the growing evidence-base on dementia-related communication difficulties, and highlight a need to develop clinical services.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":"176 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methodology Worldwide, the prevalence of frailty is increasing. Stratifying frailty can be beneficial at a population level to improve public health and target local services. At an individual level, recognition of frailty can help inform prognosis and advanced planning. The Clinical Frailty Scale (CFS) is validated for predicting outcomes of older hospitalised adults. All patients admitted into two hospitals in the South-East of England between 1 January 2017 and 31 December 2022, aged ≥65 years old with an electronically recorded CFS were included. Results Over the study period there were 100 933 admissions, representing 53 361 individual patients. A single admission was observed in 16 284 (30.5%), whilst 37 077 (69.5%) had more than one admission. The mean CFS was 4.62 (SD 1.66) and 49.5% were living with frailty (CFS ≥5). Across 6 years, before, during and after the Covid-19 pandemic, this percentage remained stable. Females had a higher average CFS than males (4.74 vs 4.46, P < 0.01). Patients with a single admission had a higher mean CFS than patients with subsequent readmissions. Patients who died during admission had a higher average CFS than those who survived to discharge (6.02 vs 4.52, P < 0.01). Conclusion This large cohort study of acutely admitted older adults found half were living with frailty. This highlights the importance of frailty identification to optimise personalised care. There was no significant change in frailty severity between 2018 and 2022.","PeriodicalId":7682,"journal":{"name":"Age and ageing","volume":"11 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144201947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study aimed to develop a bleeding risk score adapted to this specific population and this therapeutic class. Multicentre, longitudinal, prospective, observational, pharmacoepidemiologic study conducted in 60 French cardiologic and geriatric centres included consecutive patients aged ≥80 years with AF, treated with rivaroxaban and followed for at least 1 year. All thromboembolic, bleeding and clinical events, including falls, hospitalisations or deaths, were recorded every 3 months for 1 year. A predictive risk score based on the clinical variables most associated with bleeding events was developed from the total sample, randomly divided into a training sample and a validation sample. Among the 839 patients included (mean age = 86 year old, 62% women), there were 78 (9.3%) major haemorrhagic events. Variables associated with bleeding were age, anaemia, low albuminemia, amiodarone use and low creatinine clearance estimated with Cockcroft formula, grouped together as the A4C score. The A4C score better identifies bleeding risk in subjects ≥80 years than the scores already validated in younger populations, as its area under the curve in the training sample and in the validation sample was 0.73 and 0.66, respectively, whereas it was 0.49/0.55 for the HAS-BLED score, 0.53/0.50 for the HEMORR2HAGES score, 0.58/0.61 for the ATRIA score and 0.57/0.54 for the RE-LY score.
