Sarcopenia comprises a loss of muscle function and muscle mass. So far, the association between the later and mortality in older adults is inconsistent. A meta-analysis was performed to assess whether muscle mass measured by appendicular skeletal muscle mass index (ASMI) is associated with higher mortality in older adults. Articles of interest were searched for… Continue reading Low #muscle mass in #older adults and mortality: A systematic review and meta-analysis

#Erythrocyte adenosine A2B receptor prevents #cognitive and #auditory dysfunction by promoting hypoxic and metabolic reprogramming
Hypoxia drives aging and promotes age-related cognition and hearing functional decline. Despite the role of erythrocytes in oxygen (O2) transport, their role in the onset of aging and age-related cognitive decline and hearing loss (HL) remains undetermined. Recent studies revealed that signaling through the erythrocyte adenosine A2B receptor (ADORA2B) promotes O2 release to counteract hypoxia… Continue reading #Erythrocyte adenosine A2B receptor prevents #cognitive and #auditory dysfunction by promoting hypoxic and metabolic reprogramming
#Renal hemodynamics across the adult lifespan: Relevance of #flow pulsatility to chronic kidney disease
Elevated renal flow pulsatility may contribute to the pathogenesis of chronic kidney disease (CKD). The purpose of this study was to investigate the associations among age, renal flow pulsatility, and CKD biomarkers in non-CKD adults and CKD patients. MethodsNon-CKD adults (n = 415) and CKD patients (n = 136) aged between 22 and 83 years underwent the renal blood flow… Continue reading #Renal hemodynamics across the adult lifespan: Relevance of #flow pulsatility to chronic kidney disease
Tracking developmental differences in real-world social #attention across #adolescence, young adulthood and older #adulthood
Detecting and responding appropriately to social information in one’s environment is a vital part of everyday social interactions. Here, we report two preregistered experiments that examine how social attention develops across the lifespan, comparing adolescents (10–19 years old), young (20–40 years old) and older (60–80 years old) adults. In two real-world tasks, participants were immersed… Continue reading Tracking developmental differences in real-world social #attention across #adolescence, young adulthood and older #adulthood
#Cognitive #leisure activity and all-cause mortality in older adults: a 4-year community-based cohort
Cognitive leisure activity, such as reading, playing mahjong or cards and computer use, is common among older adults in China. Previous studies suggest a negative correlation between cognitive leisure activity and cognitive impairment. However, the relationship between cognitive leisure activity and all-cause mortality has rarely been reported. ObjectivesThis study aims to explore the relationships between… Continue reading #Cognitive #leisure activity and all-cause mortality in older adults: a 4-year community-based cohort
Association between self‐reported night #sleep duration and #cognitive function among older adults with intact global cognition
The purpose of this study was to clarify the association between self‐reported night sleep duration and cognitive functions such as word memory, story memory, attention, executive function, and processing speed of older adults with normal global cognitive function. Methods A total of 241 functionally independent older adults (mean age, 75.5 ± 6.4 years) participated in… Continue reading Association between self‐reported night #sleep duration and #cognitive function among older adults with intact global cognition
Efficacy of #quetiapine for #delirium prevention in hospitalized older medical patients: a randomized double-blind controlled trial
Delirium is a common disorder among hospitalized older patients and results in increased morbidity and mortality. The prevention of delirium is still challenging in older patient care. The role of antipsychotics in delirium prevention has been limited. Therefore, we conducted a trial to investigate the efficacy of quetiapine use to prevent delirium in hospitalized older… Continue reading Efficacy of #quetiapine for #delirium prevention in hospitalized older medical patients: a randomized double-blind controlled trial
A Primary Care Agenda for #Brain Health: A Scientific Statement From the American Heart Association
A healthy brain is critical for living a longer and fuller life. The projected aging of the population, however, raises new challenges in maintaining quality of life. As we age, there is increasing compromise of neuronal activity that affects functions such as cognition, also making the brain vulnerable to disease. Once pathology-induced decline begins, few… Continue reading A Primary Care Agenda for #Brain Health: A Scientific Statement From the American Heart Association
Assessment of protection against #reinfection with #SARS-CoV-2 among 4 million PCR-tested individuals in Denmark in 2020: a population-level observational study
The degree to which infection with SARS-CoV-2 confers protection towards subsequent reinfection is not well described. In 2020, as part of Denmark's extensive, free-of-charge PCR-testing strategy, approximately 4 million individuals (69% of the population) underwent 10·6 million tests. Using these national PCR-test data from 2020, we estimated protection towards repeat infection with SARS-CoV-2. Methods In… Continue reading Assessment of protection against #reinfection with #SARS-CoV-2 among 4 million PCR-tested individuals in Denmark in 2020: a population-level observational study
