Objective: To compare patterns in use of different antiemetics during pregnancy in Canada, the United Kingdom, and the United States, between 2002 and 2014.
Methods: We constructed population-based cohorts of pregnant women using administrative healthcare data from five Canadian provinces (Alberta, British Columbia, Manitoba, Ontario, and Saskatchewan), the Clinical Practice Research Datalink from the United Kingdom, and the IBM MarketScan Research Databases from the United States. We included pregnancies ending in live births, stillbirth, spontaneous abortion, or induced abortion. We determined maternal use of antiemetics from pharmacy claims in Canada and the United States and from prescriptions in the United Kingdom.
Results: The most common outcome of 3 848 734 included pregnancies (started 2002-2014) was live birth (66.7% of all pregnancies) followed by spontaneous abortion (20.2%). Use of antiemetics during pregnancy increased over time in all three countries. Canada had the highest prevalence of use of prescription antiemetics during pregnancy (17.7% of pregnancies overall, 13.2% of pregnancies in 2002, and 18.9% in 2014), followed by the United States (14.0% overall, 8.9% in 2007, and 18.1% in 2014), and the United Kingdom (5.0% overall, 4.2% in 2002, and 6.5% in 2014). Besides use of antiemetic drugs being considerably lower in the United Kingdom, the increase in its use over time was more modest. The most commonly used antiemetic was combination doxylamine/pyridoxine in Canada (95.2% of pregnancies treated with antiemetics), ondansetron in the United States (72.2%), and prochlorperazine in the United Kingdom (63.5%).
Conclusions: In this large cohort study, we observed an overall increase in antiemetic use during pregnancy, and patterns of use varied across jurisdictions. Continued monitoring of antiemetic use and further research are warranted to better understand the reasons for differences in use of these medications and to assess their benefit-risk profile in this population.

Sulfur(VI) fluoride exchange (SuFEx) compounds are gaining increasing attention due to their various applications. We present the Diels-Alder reaction of ethenesulfonyl fluoride and analogues to rapidly access cyclic and bicyclic SuFEx derivatives in moderate to good yields. These derivatives have been shown to be useful intermediates in a variety of synthetic transformations to expand the toolkit for the preparation of cyclic aliphatic sulfonyl fluorides.

Background: The association between season of screening blood pressure (BP) measurement and adverse outcomes has not been examined among populations without prior physician-diagnosed hypertension. We aimed to investigate the association between the season of screening clinic BP measurement and the risk of all-cause mortality.
Methods: This was a prospective cohort study, and data were analyzed from an ongoing community hypertension screening program in Shanghai between 2018 and 2024.

This paper explores the interrelations between medical specialisation, the changing division of medical labour and the technologies that have emerged to coordinate and integrate patient care. Drawing on the examples of the United Kingdom and the United States, countries whose health systems provide important points of commonality and distinction, I explore the intersections between the rise of medical specialisation and the creation of new medical and paramedical roles. These roles have often emerged as a palliative to the increasing fragmentation and atomisation of medical labour, to 'assist' overburdened clinicians and provide better coordinated and integrated patient care.

Preclinical stroke research faces a critical translational gap, with animal studies failing to reliably predict clinical efficacy. To address this, the field is moving toward rigorous, multicenter preclinical randomized controlled trials (mpRCTs) that mimic phase 3 clinical trials in several key components. This collective statement, derived from experts involved in mpRCTs, outlines considerations for designing and executing such trials.

Background: Evidence informing clinical guidelines assumes that all transcatheter aortic valve implantation (TAVI) devices have similar effectiveness, in other words, displaying a class effect across TAVI valves. We aimed to assess the comparative effectiveness of different TAVI platforms relative to other TAVI counterparts or surgical aortic valve replacement (SAVR).
Methods: MEDLINE/Embase/CENTRAL were searched from inception until April 2025, for randomized controlled trials comparing outcomes with different commercially available TAVI devices relative to other TAVI counterparts or SAVR.
