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
#Height Loss in Old Age and #Fracture Risk Among Men in Late Life: A Prospective Cohort Study
To assess the association of height loss in old age with subsequent risk of hip and any clinical fracture in men late in life while accounting for the competing risk of mortality, we used data from 3,491 community‐dwelling men (mean age 79.2 years). Height loss between baseline and follow‐up (mean 7.0 years between examinations) was… Continue reading #Height Loss in Old Age and #Fracture Risk Among Men in Late Life: A Prospective Cohort Study
An integrative study of five biological #clocks in somatic and mental #health
Biological clocks have been developed at different molecular levels and were found to be more advanced in the presence of somatic illness and mental disorders. However, it is unclear whether different biological clocks reflect similar aging processes and determinants. In ~3000 subjects, we examined whether five biological clocks (telomere length, epigenetic, transcriptomic, proteomic, and metabolomic… Continue reading An integrative study of five biological #clocks in somatic and mental #health
