Association of SARS-CoV-2 infection with physical activity domains and types.

Lockdown imposed in the early phase of the SARS-CoV-2 outbreak represented a specific setting where activity was restricted but still possible. The aim was to investigate the cross-sectional associations between physical activity (PA) and SARS-CoV-2 infection in a French population-based cohort. Participants completed a PA questionnaire.

ABO blood types and SARS-CoV-2 infection assessed using seroprevalence data in a large population-based sample: the SAPRIS-SERO multi-cohort study.

ABO blood type has been reported as a potential factor influencing SARS-CoV-2 infection, but so far mostly in studies that involved small samples, selected population and/or used PCR test results. In contrast our study aimed to assess the association between ABO blood types and SARS-CoV-2 infection using seroprevalence data (independent of whether or not individuals had symptoms or sought for testing) in a large population-based sample. Our study included 67,340 French participants to the SAPRIS-SERO multi-cohort project.

Perceived discomfort and neuromuscular fatigue during long-duration real driving with different car seats.

Introduction: Identification of the seat features that could improve driving experience is a main issue for automotive companies.

Objective: Long duration real driving sessions were performed to assess the effect of three seats (soft-S1, firm-S2 and suspended-S3) on perceived discomfort and neuromuscular fatigue (NMF).

Materials & Methods: For each seat, the muscular activity of bilateral Trapezius Descendens (TD), Erector Spinae (ES) and Multifidus (MF) muscles of twenty-one participants was recorded during real driving sessions of 3-hours each lasting approximately 3 hours and following the same itinerary.

cIAP1/TRAF2 interplay promotes tumor growth through the activation of STAT3.

Cellular inhibitor of apoptosis-1 (cIAP1) is a signaling regulator with oncogenic properties. It is involved in the regulation of signaling pathways controlling inflammation, cell survival, proliferation, differentiation and motility. It is recruited into membrane-receptor-associated signaling complexes thanks to the molecular adaptor TRAF2.

Exposome Profiles and Asthma among French Adults.

Although previous studies in environmental epidemiology focused on single or a few exposures, a holistic approach combining multiple preventable risk factors is needed to tackle the etiology of multifactorial diseases such as asthma. To investigate the association between combined socioeconomic, external environment, early-life environment, and lifestyle-anthropometric factors and asthma phenotypes. A total of 20,833 adults from the French NutriNet-Santé cohort were included (mean age, 56.
