Maternal Chronic Physical Conditions and Alcohol and Substance Use Disorders in the Preconception and Perinatal Periods.

Chronic physical conditions (CPC) and alcohol and substance use disorders (SUD) frequently co-occur, but this has not been examined perinatally. We explored the combined effects of CPC and prepregnancy SUD on perinatal SUD-related adverse events and outpatient care. This population-based study comprised 77,474 people with and 664,751 without CPC with a birth in Ontario, Canada, 2013-2020.

The impact of osteopathic recognition on multiple medical specialty residencies in a university-based setting.

Context: In 2020, the allopathic and osteopathic residency programs were merged into a single residency system, with the Accreditation Council for Graduate Medical Education (ACGME) as the sole accreditor for residencies and fellowships in the United States. As a result of this merger, osteopathic recognition (OR) emerged as a unique approach to promoting osteopathic training and practice. However, there is a lack of data on the effects of OR in residency, specifically university-based residency programs.

Glucagon-Like Peptide 1 Receptor Agonists and Risk of Thyroid Cancer: An International Multisite Cohort Study.

Concerns have been raised that glucagon-like peptide 1 receptor agonists (GLP1-RAs) may increase the risk of thyroid cancer, but evidence remains conflicting. We therefore investigated if GLP1-RA use, compared with use of dipeptidyl peptidase-4 inhibitors (DPP-4is), was associated with thyroid cancer risk in patients with type 2 diabetes. This multisite cohort study with subsequent meta-analysis included six population-based databases from Canada (Ontario), Denmark, Norway, South Korea, Sweden, and Taiwan.

Sex Differences in Participation and Performance Trends in Time-Limited Ultramarathon Events.

We aimed to analyze sex differences in time-limited ultramarathon participation, while also identifying trends in participation, age, and performance across different formats of events, from 1990 to 2020. This is an exploratory study, using data obtained from the official event web pages. We downloaded information regarding the year of the event, athletes' year of birth, sex, race event, ranking, and mean running speed (km/h).

Antarctic Expeditions: A Systematic Review of the Physiological, Nutritional, Body Composition and Psychological Responses to Treks Across the Continental Ice.

Background: Antarctic expeditions, although supported by scientific knowledge, face various challenges, with little research conducted to explore the physical demands that explorers experience.

Objective: To summarise physiological, psychological, body composition and nutritional changes faced during trek expeditions in the Antarctic's continental portion.

Design: Systematic review.
