The differing relationships between academic discipline, sleep hygiene, and dysfunctional sleep attitudes on sleep quality and duration in Canadian university students.

Objectives: This study sought to understand how university student's academic discipline relates to sleep factors including attitudes, hygiene, quality, and duration.

Methods: Using a cross-sectional approach, a 30-min survey was advertised to students at two Canadian universities in March of 2022. Sleep measures included the Dysfunctional Beliefs and Attitudes Scale, the Sleep Hygiene Index, the Pittsburgh Sleep Quality Index, and the Insomnia Severity Index.

Short-term vascular responses to spring and fall daylight savings time shifts.

Daylight saving time (DST) is a Western biannual time transition, setting the clock back 1 h in the fall and forward 1 h in the spring. There is an epidemiological link between DST and acute myocardial infarction risk in the first week following the spring shift; however, the mechanisms underlying the effect of DST on cardiovascular function remain unclear. The purpose of this study was to explore the short-term cardiovascular changes induced by fall and spring shifts in DST in a convenience sample of healthy adults.

Cardiorespiratory Fitness May Protect Memory for Poorer Sleepers.

Objectives: Physical activity has been shown to protect executive functions against the deleterious effects of poorer sleep among older adults (OA); however, it is unknown whether memory is protected too, and if this relationship differs by age. The present study investigated the relationship between cardiorespiratory fitness, sleep, and memory in both older and young adults (YA).

Methods: This observational study recruited 26 OA (70.

Optimizing Sleep in Older Adults: Where Does High-Intensity Interval Training Fit?

The present community-based study evaluated the effect of three different exercise interventions on sleep quality. Older adults were enrolled in one of three exercise intervention groups: high-intensity interval training (HIIT; = 20), moderate-intensity continuous training (MICT; = 19) or stretching (STRETCH; = 22). Prior to and following the intervention, sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).

Low-cost sensors as an alternative for long-term air quality monitoring.

Low-cost air quality sensors are increasingly being used in many applications; however, many of their performance characteristics have not been adequately investigated. This study was conducted over a period of 13 months using low-cost air quality monitors, each comprising two low-cost sensors, which were subjected to a wide range of pollution sources and concentrations, relative humidity and temperature at four locations in Australia and China. The aim of the study was to establish the performance characteristics of the two low-cost sensors (a Plantower PMS1003 for PM and an Alphasense CO-B4 for carbon monoxide, CO) and the KOALA monitor as a whole under various conditions.

Treatment of Severe Alcohol Withdrawal: A Focus on Adjunctive Agents.

To review adjunctive treatment options for severe alcohol withdrawal. The search strategy included a search of Ovid MEDLINE using keywords , , , , , , , , , and and included articles dated from January 1990 to March 2017. All English-language clinical trials and case reports assessing the efficacy of adjunctive agents in severe alcohol withdrawal were evaluated.
