Background: Few studies of the association between accelerometry-assessed physical activity with major depressive disorder (MDD) have considered the influence of both the averages and variability of all three domains of the 24 hour activity cycle including sleep, physical activity, and circadian rhythmicity, the physical health correlates of depression, and the extent to which changes in sleep and physical activity reflect current state versus enduring patterns of MDD in people with depression.

Methods: The sample includes 2307 participants from a population cohort from Lausanne, Switzerland. Average and variability of daily sleep (SL), physical activity (PA), and circadian rhythmicity (CR) were derived from accelerometry.

Introduction: The adoption of age or individualized body surface area (i-BSA) estimated glomerular filtration rate (eGFR) thresholds could influence the prevalence and prognosis of chronic kidney disease (CKD). This longitudinal study with up to 15 years of follow-up in the general population, compares different eGFR thresholds for CKD definition: standard, corrected to i-BSA, and age-stratified. For each, we assessed the prevalence of CKD and the combined impact on rapid renal function decline (RRFD) and mortality.

Study Aims: Sarcopenia is a progressive, age-related loss of muscle mass, strength and function. Given the ageing population and the adverse outcomes associated with sarcopenia, monitoring its epidemiology is particularly important. This study aimed to describe sarcopenia prevalence, 5-year incidence and agreement between definitions using the latest operational criteria in Swiss postmenopausal women.

Background: Sleep apnoea specific heart rate response (ΔHR) has been identified as a promising biomarker for stratifying cardiovascular (CV) risk, and predicting positive airway pressure (PAP) benefit in obstructive sleep apnoea (OSA). However, the need for prior manual scoring of respiratory events potentially limits the accessibility and reproducibility of ΔHR. We aimed to evaluate the association of pulse rate response to oxygen desaturations automatically derived from pulse oximetry (ΔHR) with CV risk in OSA.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

We aimed to identify and validate factors related to uncontrolled hypertension. Participants treated with at least one antihypertensive drug from the prospective contemporaneous CoLaus|PsyCoLaus study were enrolled. We investigated the association between hypertension status (uncontrolled, defined as systolic blood pressure [SBP] ≥ 140 mm Hg and/or diastolic blood pressure [DBP] ≥ 90 mm Hg, versus controlled hypertension [SBP/DBP < 140/90 mm Hg]) and potential risk factors.

Given the association of Epstein-Barr virus (EBV) with subjective perception of fatigue and demyelination in clinical conditions, the question about potential subclinical effects in the adult general population remains open. We investigate the association between individuals' EBV immune response and perceived fatigue in a community dwelling cohort (n = 864, age 62 ± 10 years old; 49% women) while monitoring brain tissue properties. Fatigue levels are assessed with the established fatigue severity scale, the EBNA-1 and VCA p18 immunoglobulin G (IgG) chronic response - with multiplex serology and the estimates of local brain volume, myelin content, and axonal density - using relaxometry- and multi-shell diffusion-based magnetic resonance imaging (MRI).

Switzerland already suffers from the long-predicted shortage of physicians. Moreover, the latter often face long and meandering postgraduate training. At the beginning of their career, most doctors work on internal medicine hospital wards, even though their future may just as well lie in an outpatient or inpatient setting, in general internal medicine or in other disciplines.

Article Synopsis
  • Drug dosing guidelines are based on average responses in the population, but individual differences can lead to ineffective treatment or adverse reactions due to genetic factors affecting drug metabolism.
  • A study genotyped 1533 Swiss patients to assess the prevalence of actionable genetic variants in relation to drug prescriptions, finding that 97.3% of participants had at least one variant.
  • The research indicates that 31% of patients received medications that could lead to adverse reactions due to these genetic variants, suggesting that personalized medicine could improve healthcare outcomes.

Background: Only few previous cohort studies examined simultaneously predictors of chronic pain (CP) onset and recovery. Furthermore, these studies used various sociodemographic and pain-related characteristics, without standardized measures of sleep and depression. The present study aimed at expanding and strengthening these findings in a large Swiss population.

Although both short and long sleep duration are associated with elevated hypertension risk, our understanding of their interplay with biological pathways governing blood pressure remains limited. To address this, we carried out genome-wide cross-population gene-by-short-sleep and long-sleep duration interaction analyses for three blood pressure traits (systolic, diastolic, and pulse pressure) in 811,405 individuals from diverse population groups. We discover 22 novel gene-sleep duration interaction loci for blood pressure, mapped to 23 genes.

Article Synopsis
  • The study investigates how accelerometry data, covering sleep, physical activity, and circadian rhythms, relates to mood disorders like major depressive disorder (MDD), moving beyond traditional research that often examined these factors in isolation.
  • The Joint and Individual Variation Explained (JIVE) method was used to analyze data from 2,317 adults in Switzerland, identifying key components from accelerometry data linked to both current and remitted MDD.
  • Results indicated that certain joint components explain a significant portion of variation in sleep and activity patterns, with distinct associations found between these components and both ongoing and past depressive states.

Article Synopsis
  • * Key findings showed that higher scores on the Epworth Sleepiness Scale and the presence of insomnia symptoms were associated with a greater risk of developing MDD, with specific hazard ratios calculated for both factors.
  • * Notably, men with increased rapid eye movement (REM) sleep had a higher MDD incidence, while women with higher delta power in their sleep showed a lower incidence, indicating gender differences in how sleep affects depression risk.

Introduction: In 2020, the European Society of Cardiology (ESC) recommends 150 min of moderate or 75 min of vigorous-intensity PA per week. While general population PA adherence is suboptimal, its status among those with previous ASCVD or high ASCVD risk remains unknown. We aimed to assess objective adherence to ESC PA recommendations using accelerometer-based measurement among these populations.

  • - The study aimed to evaluate how accurate self-reported caffeine consumption is by comparing it to actual plasma levels of caffeine and its metabolites in a community setting.
  • - Utilizing data from two large Swiss studies, researchers found discrepancies between self-reported caffeine intake and measured plasma levels, particularly noticing a change in trend after 3-5 cups of coffee per day.
  • - The results suggest that self-reports of low or high caffeine consumption can be misleading, highlighting the benefit of measuring plasma levels for better assessing caffeine intake.

Article Synopsis
  • * The research showed that individuals with high polygenic risk scores have significantly higher blood pressure (almost 17 mmHg more) and over seven times the risk of developing hypertension compared to those with low scores.
  • * Incorporating these genetic risk scores into hypertension prediction models improved their accuracy, and excitingly, similar genetic associations were found in a large African-American sample, underscoring the potential of these findings for precision health initiatives.

Despite major advances, our understanding of the neurobiology of life course socioeconomic conditions is still scarce. This study aimed to provide insight into the pathways linking socioeconomic exposures-household income, last known occupational position, and life course socioeconomic trajectories-with brain microstructure and cognitive performance in middle to late adulthood. We assessed socioeconomic conditions alongside quantitative relaxometry and diffusion-weighted magnetic resonance imaging indicators of brain tissue microstructure and cognitive performance in a sample of community-dwelling men and women ( = 751, aged 50-91 years).

Whether cardiovascular risk scores geographically aggregate and inform on spatial development of atherosclerotic cardiovascular diseases (ASCVD) remains unknown. Our aim is to determine the spatial distribution of 10-year predicted cardiovascular risk and ASCVD, and to compare the overlap of the resulting spatial distributions. Using prospective data from the CoLaus|PsyCoLaus cohort study (2003-2021) we computed SCORE2 in participants free from ASCVD.
