Are humans facing a sleep epidemic or enlightenment? Large-scale, industrial societies exhibit long, efficient sleep yet weak circadian function.

The Centers for Disease Control and Prevention declared sleep-related problems to be a public health epidemic. With the advent of biometric sleep tracking technology taking the sleep lab into the field, the study of human sleep is now global, and these new datasets show contrasting findings. Previous reports suggest sleep in small-scale, non-industrial societies to be short and fragmented yet characterized by greater circadian rhythmicity.

Low-to-Moderate Daytime Physical Activities Predicted Higher-Quality Sleep Among Habitually Active Agropastoralists.

Introduction: The positive effects of physical activity (PA) on sleep are widely promoted by public health organizations and supported by abundant empirical evidence. Nonetheless, there remains a dearth of studies investigating the association between daytime PA and nighttime sleep among non-urban and nonindustrial populations that habitually engage in PA as part of their subsistence strategy.

Methods: Here, we examined the bidirectional relationship between PA and sleep.

The impact of Daylight Saving Time on dog activity.

While most studies on Daylight Saving Time (DST) focus on human sleep and well-being, there is a dearth of understanding of how this sudden, human-mitigated change affects the routines of companion animals. The objective of this study was to assess how DST influenced the morning activity pattern of dogs (Canis familiaris). We used accelerometers to record activity in 25 sled dogs and 29 caregiver-companion dog dyads located in or near Ontario, Canada during the Fall Back time shift.

Outcomes on 287 Patients with Complex Abdominal Wall Defects Undergoing Abdominal Wall Reconstruction with a Porcine-Derived Acellular Matrix.

Introduction: Complex abdominal wall defects (CAWD) requiring complex abdominal wall reconstruction (CAWR) represent an important surgical challenge in the presence of significant comorbidities. We aimed to report the results on a large patient cohort and identify independent outcome predictors.

Materials And Methods: All patients who underwent CAWR with biologic mesh (Strattice™; Reconstructive Tissue Matrix ®, a porcine-derived acellular dermal matrix; Allergan plc, Branchburg, New Jersey) between July 2016 and November 2021 at the tertiary academic center were studied using univariable and multivariable regressions.

Decreasing Trends of Traumatic Brain Injury Despite a Surge in Anticoagulant Use in the Elderly.

Background: In recent years, with the introduction of new anticoagulants there has been a rise in their usage among elderly population who are at risk for traumatic brain injury (TBI) at the same time. We assessed the change in use of anticoagulant in elderly trauma patients and its association with TBI outcomes.

Material And Methods: We performed a 5-y retrospective analysis of Trauma Quality Improvement Program (2017-2021) of trauma patients ≥65 y.
