Persistent psychological stress increases the risk of many chronic diseases of aging. Little progress has been made to effectively reduce stress responses or mitigate stress effects suggesting a need for better understanding of factors that influence stress responses. Limited evidence suggests that diet may be a factor in modifying the effects of stress. However, long-term… Continue reading #Mediterranean diet, #stress resilience, and aging in nonhuman primates

Elevated #LDL cholesterol and increased risk of myocardial #infarction and #atherosclerotic cardiovascular disease in individuals aged 70–100 years: a contemporary primary prevention cohort
Findings of historical studies suggest that elevated LDL cholesterol is not associated with increased risk of myocardial infarction and atherosclerotic cardiovascular disease in patients older than 70 years. We aimed to test this hypothesis in a contemporary population of individuals aged 70–100 years.. ..Between Nov 25, 2003, and Feb 17, 2015, 91 131 individuals were enrolled… Continue reading Elevated #LDL cholesterol and increased risk of myocardial #infarction and #atherosclerotic cardiovascular disease in individuals aged 70–100 years: a contemporary primary prevention cohort
Factors associated with social #isolation and being homebound among #older patients with #diabetes: a cross-sectional study
We aimed at investigating factors associated with social isolation and being homebound in older patients with diabetes.. ..Social isolation was defined as indulging in less than one interaction per week with individuals other than cohabiting family members. We defined homebound as going outside home less than once a day. To identify factors associated with social… Continue reading Factors associated with social #isolation and being homebound among #older patients with #diabetes: a cross-sectional study
Residential context and #COVID-19 mortality among adults aged 70 years and older in Stockholm: a population-based, observational study using individual-level data
Housing characteristics and neighbourhood context are considered risk factors for COVID-19 mortality among older adults. The aim of this study was to investigate how individual-level housing and neighbourhood characteristics are associated with COVID-19 mortality in older adults.. ..Of 279 961 individuals identified to be aged 70 years or older on March 12, 2020, and residing in… Continue reading Residential context and #COVID-19 mortality among adults aged 70 years and older in Stockholm: a population-based, observational study using individual-level data
#Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress
Key points In humans, hypohydration attenuates sweat secretion and attenuates whole‐body heat loss, probably to mitigate further fluid losses and thereby support blood pressure regulation. Recently, however, we demonstrated that the hypohydration‐mediated reduction in net whole‐body heat exchange (evaporative heat loss – dry heat gain) was blunted in middle‐aged compared to younger men during moderate… Continue reading #Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress
The temporal association between incident late‐life #depression and incident #dementia
There is an established association between depression and subsequent dementia. The present study examined temporal associations between incident late‐life depression and subsequent dementia, also considering age and sex.. ..Incident depression was associated with a higher risk of subsequent dementia (incidence rate ratios (IRR) adjusted for age and sex: IRR = 1.58, 95% CI = 1.51‐1.64).… Continue reading The temporal association between incident late‐life #depression and incident #dementia
Association of Statin Use With All-Cause and Cardiovascular Mortality in US Veterans 75 Years and Older
Data are limited regarding statin therapy for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in adults 75 years and older.. ..Of 326 981 eligible veterans (mean [SD] age, 81.1 [4.1] years; 97% men; 91% white), 57 178 (17.5%) newly initiated statins during the study period. During a mean follow-up of 6.8 (SD, 3.9) years, a total 206 902… Continue reading Association of Statin Use With All-Cause and Cardiovascular Mortality in US Veterans 75 Years and Older
Trimethylamine-N-Oxide Promotes Age-Related Vascular Oxidative Stress and Endothelial Dysfunction in Mice and Healthy Humans
Age-related vascular endothelial dysfunction is a major antecedent to cardiovascular diseases. We investigated whether increased circulating levels of the gut microbiome-generated metabolite trimethylamine-N-oxide induces endothelial dysfunction with aging. In healthy humans, plasma trimethylamine-N-oxide was higher in middle-aged/older (64±7 years) versus young (22±2 years) adults (6.5±0.7 versus 1.6±0.2 µmol/L) and inversely related to brachial artery flow-mediated… Continue reading Trimethylamine-N-Oxide Promotes Age-Related Vascular Oxidative Stress and Endothelial Dysfunction in Mice and Healthy Humans
Predictors of a long length of stay in the emergency department for older people
..For older people, a long stay in the emergency department (ED) may reflect the complexity of their presentation, or deficiencies in systems that manage these complexities. ..Of 16 791 ED presentations made by older people, 4192 experienced a LLoS; 55% were admitted. Increasing age was associated with an increasing ED LoS. Factors most predictive of LLoS… Continue reading Predictors of a long length of stay in the emergency department for older people
