Frailty is characterized by diminished resilience to stressor events. It is associated with adverse future health outcomes and impedes healthy aging. The circadian system orchestrates ~24-h rhythms in bodily functions in synchrony with the day-night cycle, and disturbed circadian regulation plays an important role in many age-related health consequences. We investigated prospective associations of circadian… Continue reading #Circadian disturbances and #frailty risk in #older adults

The psychophysiology of Mastermind: Characterizing response times and #blinking in a high-stakes television game show
Television game shows have proven to be a valuable resource for studying human behavior under conditions of high #stress and high stakes. However, previous work has focused mostly on choices—ignoring much of the rich visual information that is available on screen. Here, we take a first step to extracting more of this information by investigating… Continue reading The psychophysiology of Mastermind: Characterizing response times and #blinking in a high-stakes television game show
Lower serum #testosterone is associated with increased likelihood of #arthritis
Studies have suggested that serum testosterone levels may be strongly correlated with the pathogenesis of arthritis. Therefore, the aim of this study was to assess the relationship between serum testosterone levels and arthritis in US adults using the National Health and Nutrition Examination Survey (NHANES). We used the database from NHANES, 2013–2016 to perform a… Continue reading Lower serum #testosterone is associated with increased likelihood of #arthritis
Effect of Dietary #Sodium on Blood #PressureA Crossover Trial
Dietary sodium recommendations are debated partly due to variable blood pressure (BP) response to sodium intake. Furthermore, the BP effect of dietary sodium among individuals taking antihypertensive medications is understudied.Objectives To examine the distribution of within-individual BP response to dietary sodium, the difference in BP between individuals allocated to consume a high- or low-sodium diet first,… Continue reading Effect of Dietary #Sodium on Blood #PressureA Crossover Trial
The #Quadriceps: A Physician’s In-Depth Look at a #Muscular Marvel
As a physician with a passion for human anatomy, I’ve always been intrigued by the intricacies of the human body. Today, we venture into the world of the quadriceps, a powerful group of muscles that is pivotal for movement and strength. Join me in this exploration of the anatomy and clinical relevance of the quadriceps… Continue reading The #Quadriceps: A Physician’s In-Depth Look at a #Muscular Marvel
Association between #sleep hours and changes in #cognitive function according to the morningness-eveningness type: A population-based study
The aim of this study was to investigate proper sleep hours to reduce the risk of cognitive decrease considering morningness-eveningness type.MethodsThe Korean Community Health Survey was used, which includes adults aged over 19 years old. These data were obtained from a cross-sectional study and assessed sleep hours using questionnaire of Pittsburgh Sleep Quality Index. Based on the wake-up time… Continue reading Association between #sleep hours and changes in #cognitive function according to the morningness-eveningness type: A population-based study
Associations between Metabolomic Biomarkers of #Avocado Intake and #Glycemia in the Multi-Ethnic Study of Atherosclerosis
BackgroundAvocado consumption is linked to better glucose homeostasis, but small associations suggest potential population heterogeneity. Metabolomic data capture the effects of food intake after digestion and metabolism, thus accounting for individual differences in these processes.ObjectivesTo identify metabolomic biomarkers of avocado intake and to examine their associations with glycemia.MethodsBaseline data from 6224 multi-ethnic older adults (62% female) included self-reported avocado… Continue reading Associations between Metabolomic Biomarkers of #Avocado Intake and #Glycemia in the Multi-Ethnic Study of Atherosclerosis

To investigate the association between mobile phone exposure and semen parameters.A nationwide cross-sectional study.SettingAndrology laboratories in close proximity to 6 army recruitment centers.PatientsIn total, 2886 men from the general Swiss population, 18–22 years old, were recruited between 2005 and 2018 during military conscription.InterventionParticipants delivered a semen sample and completed a questionnaire on health and lifestyle,… Continue reading Association between self-reported mobile #phone use and the #semen quality of young men
Polygenic predisposition, #sleep duration, and #depression: evidence from a prospective population-based cohort
Suboptimal sleep durations and depression frequently cooccur. Short-sleep and long-sleep are commonly thought of as symptoms of depression, but a growing literature suggests that they may be prodromal. While each represents a process of mutual influence, the directionality between them remains unclear. Using polygenic scores (PGS), we investigate the prospective direction involved in suboptimal sleep… Continue reading Polygenic predisposition, #sleep duration, and #depression: evidence from a prospective population-based cohort
