Temporal trends in aerobic physical activity guideline adherence among nationally representative samples of U.S adults between 2011 and 2019: Cross-sectional findings from a sample of over 2 million adults.

Background: Physical inactivity is a significant public health concern associated with numerous adverse health outcomes and substantial economic costs. This study describes the prevalence, trends and correlates for adherence to moderate to vigorous physical activity (MVPA) guidelines among a large sample of U.S.

Weight training and risk of all-cause, cardiovascular disease and cancer mortality among older adults.

Background: While previous studies indicate muscle-strengthening exercises may reduce mortality risk, further research is needed to increase certainty of the evidence. We investigated overall and dose-response associations between weight training and the risks of all-cause, cardiovascular disease (CVD) and cancer mortality in a large cohort of older adults with long follow-up time and a large number of deaths. We also investigated the joint associations of weight training and aerobic exercise with mortality risk.

Penetrance interactions of colour pattern loci in the African Monarch and their implications for the evolution of dominance.

Scoring the penetrance of heterozygotes in complex phenotypes, like colour pattern, is difficult and complicates the analysis of systems in which dominance is incomplete or evolving. The African Monarch () represents an example where colour pattern heterozygotes, formed in the contact zone between the different subspecies, show such intermediate dominance. Colour pattern in this aposematic butterfly is controlled by three loci , and .

Changing streetlighting schemes and the ecological availability of darkness.

Artificial light at night (ALAN), from streetlights and other sources, has a wide variety of impacts on the natural environment. A significant challenge remains, however, to predict at intermediate spatial extents (e.g.

What does routine depression screening in the ambulatory orthopedic clinic teach us? Results from nearly 60,000 patient encounters.

Background: It remains unclear what role depression screening plays in routine ambulatory orthopedic care. The purpose of this study was to determine (1) the floor and ceiling effects of the Patient-Reported Outcomes Measurement Information System Depression (PROMIS-D) form, (2) the prevalence of positive PROMIS-D screening forms across an orthopedic service line, and (3) the prevalence of previously diagnosed depression and interventions among a representative sample of patients.

Methods: This retrospective study analyzed 58,227 patients who presented to ambulatory orthopedic clinics across an orthopedic service line between January 1, 2019 to December 31, 2021.
