#Depression and increased risk of #Alzheimer’s #dementia: longitudinal analyses of modifiable risk and sex-related factors.

Highlights •We investigated whether recent and/or remote depression was associated with increased risk of Alzheimer’s Dementia (AD) and whether this risk differed between men and women. •Recent depression was independently associated with increased risk of incident AD while remote depression was not. Recent depression was predictive of AD development in females, but not in males, while sex did not moderate recent depression-associated risk of developing … Continue reading #Depression and increased risk of #Alzheimer’s #dementia: longitudinal analyses of modifiable risk and sex-related factors.

Older Adults and the Mental Health Effects of #COVID-19

As the coronavirus disease 2019 (COVID-19) began to spread in the US in early 2020, older adults experienced disproportionately greater adverse effects from the pandemic including more severe complications, higher mortality, concerns about disruptions to their daily routines and access to care, difficulty in adapting to technologies like telemedicine, and concerns that isolation would exacerbate existing mental health conditions. Older adults tend to have lower … Continue reading Older Adults and the Mental Health Effects of #COVID-19

#Older age does not influence the success of #weight loss through the implementation of lifestyle modification

Age is sometimes a barrier for acceptance of patients into a hospital‐based obesity service. Our aim was to explore the effect of age on the ability to lose weight through lifestyle interventions, implemented within a hospital‐based obesity service.. Primary outcome measures were percentage weight loss (%WL) and percentage reduction in body mass index (%rBMI) following implemented lifestyle interventions. Data were stratified according to patient age … Continue reading #Older age does not influence the success of #weight loss through the implementation of lifestyle modification

#Mediterranean diet, #stress resilience, and aging in nonhuman primates

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 studies of diet effects on stress reactive systems are not … 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 in CGPS. During mean 7·7 (SD 3·2) years of follow-up … 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 isolation and being homebound, we performed logistic regression analysis. The … Continue reading Factors associated with social #isolation and being homebound among #older patients with #diabetes: a cross-sectional study

Vitamin #D Insufficiency Reduces Grip Strength, Grip Endurance and Increases Frailty in Aged C57Bl/6J Mice

Low 25-OH serum vitamin D (VitD) is pervasive in older adults and linked to functional decline and progression of frailty. We have previously shown that chronic VitD insufficiency in “middle-aged” mice results in impaired anaerobic exercise capacity, decreased lean mass, and increased adiposity. Here, we examine if VitD insufficiency results in similar deficits and greater frailty progression in old-aged (24 to 28 months of age) … Continue reading Vitamin #D Insufficiency Reduces Grip Strength, Grip Endurance and Increases Frailty in Aged C57Bl/6J Mice

#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 exercise in dry heat; albeit, the underpinning mechanisms could not … Continue reading #Ageing attenuates the effect of extracellular hyperosmolality on whole‐body #heat exchange during exercise‐heat #stress

Infection Fatality Ratios for #COVID-19 Among Noninstitutionalized Persons 12 and Older: Results of a Random-Sample Prevalence Study

Background: Because many cases of coronavirus disease 2019 (COVID-19) are asymptomatic, generalizable data on the true number of persons infected are lacking. Mortality rates therefore are calculated from confirmed cases, which overestimates the infection fatality ratio (IFR). To calculate a true IFR, population prevalence data are needed from large geographic areas where reliable death data also exist. Most previous IFR estimates came from non-U.S. populations, … Continue reading Infection Fatality Ratios for #COVID-19 Among Noninstitutionalized Persons 12 and Older: Results of a Random-Sample Prevalence Study

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). The strongest association was found for the shortest interval of … Continue reading The temporal association between incident late‐life #depression and incident #dementia

Association Between Arterial #Stiffness, #Frailty and Fall-Related Injuries in Older Adults

..A cross-sectional study of a random sample of older adults aged 60 years and older was conducted. Main study parameters: arterial stiffness was measured by the determining the cardio-ankle vascular index (CAVI); Frailty status was defined using a 7-item frailty screening scale, developed in Russia. This questionnaire included question about falls and fall-related injuries. Orthostatic test and anthropometric tests were done. Medical history (comorbidity, medications), … Continue reading Association Between Arterial #Stiffness, #Frailty and Fall-Related Injuries in Older Adults

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 deaths occurred including 53 296 cardiovascular deaths, with 78.7 and 98.2 … Continue reading Association of Statin Use With All-Cause and Cardiovascular Mortality in US Veterans 75 Years and Older
