Purpose: The aim of this study was to determine the causes of death in the very elderly.
Methods: We reviewed 24,081 consecutive autopsies performed over 10 years (1989 to 1998) at the Institute of Forensic Medicine, Vienna, Austria. We focused on autopsies of people aged 85 years or older who died unexpectedly out of hospital.
Results: The mean age of the 1886 patients (561 men and 1325 women) at the time of death was 88 +/- 3 years (range, 85 to 108 years). Thirty-one percent (n = 588) of those who died were described as having been previously healthy. Cardiovascular disease was the most common cause of death (n = 1465 [77%]). Thirteen percent (n = 246) died of respiratory illness, 5% (n = 94) of gastrointestinal disorders, and 3% (n = 53) of diseases of the central nervous system. Genitourinary and metabolic diseases were uncommon.
Conclusion: Although this out-of-hospital sample is not representative of the entire elderly population, postmortem examinations emphasize the importance of cardiovascular diseases in causing unexpected deaths in older persons.

Testing the mediating mechanism of alcohol use on the association between retirement and depressive symptoms in the United States using generalized mixed effect models.
Aging Ment Health
January 2025
School of Social Work, Simmons University, Boston, MA, USA.
Objectives: Both alcohol use and the prevalence of depression-depressive disorders, among older adults have increased over the past several decades and have been associated with increased morbidity and mortality. To our knowledge, the interactions between retirement, depression, and alcohol use have not yet been examined. This study aims to longitudinally explore the mediating role of alcohol use on the association between retirement and depressive symptoms in the United States, comparing individuals who are retired and not retired, while also exploring individuals who transitioned into and out of retirement at different times.

J Hypertens
December 2024
Department of Ultrasound Medicine, Tangdu Hospital, Air Force Medical University.
Background: The arterial stiffening is attributed to the intrinsic structural stiffening and/or load-dependent stiffening by increased blood pressure (BP). The respective lifetime alterations and major determinants of the two components with normal aging are not clear.
Methods: A total of 3053 healthy adults (1922 women) aged 18-79 years were enrolled.
Strategies to Increase Response Rate and Reduce Nonresponse Bias in Population Health Research: Analysis of a Series of Randomized Controlled Experiments during a Large COVID-19 Study.
JMIR Public Health Surveill
January 2025
School of Public Health, Imperial College London, London, United Kingdom.
Background: High response rates are needed in population-based studies, as nonresponse reduces effective sample size and bias affects accuracy and decreases the generalizability of the study findings.
Objective: We tested different strategies to improve response rate and reduce nonresponse bias in a national population-based COVID-19 surveillance program in England, United Kingdom.
Methods: Over 19 rounds, a random sample of individuals aged 5 years and older from the general population in England were invited by mail to complete a web-based questionnaire and return a swab for SARS-CoV-2 testing.

Department of Neurology and the Franke Barrow Global Neuroscience Education Center, Barrow Neurological Institute, Phoenix, AZ, USA.
Background: The aim of this study was to examine the potential added value of including neuropsychiatric symptoms (NPS) in machine learning (ML) models, along with demographic features and Alzheimer's disease (AD) biomarkers, to predict decline or non-decline in global and domain-specific cognitive scores among community-dwelling older adults.
Objective: To evaluate the impact of adding NPS to AD biomarkers on ML model accuracy in predicting cognitive decline among older adults.
Methods: The study was conducted in the setting of the Mayo Clinic Study of Aging, including participants aged ≥ 50 years with information on demographics (i.
