Objective: To evaluate the effect of laryngoplasty (LP) on race performance in longer distance (National Hunt) Thoroughbred racehorses.
Study Design: Case-control study.
Animals: National Hunt Thoroughbred racehorses (n=71) and race-matched controls (n=126).
Methods: Race records for National Hunt racehorses that had LP and ventriculocordectomy were analyzed and racing performance was compared with race-matched controls.
Results: Sixty-three of 71 cases were matched with controls. Postoperatively, 78% of cases raced, 47% improved their individual performance and cases were as likely to start in 1 or 3 races as controls. In the 5 preoperative races, case horses earned less prize money than race-matched controls but there was no difference in prize money earned in 5 postoperative races between groups. Cases started in significantly fewer total (lifetime) races both before and after the date of surgery compared with controls.
Conclusions: LP seemingly restored short-term postoperative racing performance of National Hunt horses to a level comparable with that of a matched control population; however, the career "longevity" of case horses appears to be shorter than that of control horses.
Clinical Relevance: LP appears to be a suitable treatment for recurrent laryngeal neuropathy in National Hunt racehorses.

Prevalence of hypertensive disorders of pregnancy and chronic hypertension increased throughout the COVID-19 pandemic in South Carolina (2015-2021).

Hypertensive disorders of pregnancy (HDP) and chronic hypertension (CHTN) are related to maternal and infant morbidity and mortality. We aimed to assess HDP and CHTN prevalence changes before (January 2015-February 2020) and during the COVID-19 pandemic (March 2020-December 2021) in South Carolina (SC). SC live births (2015-2021) were included (194,841 non-Hispanic White [NHW]); 108,195 non-Hispanic Black [NHB]; 25,560 Hispanic; 16,346 other race/ethnicity).

Background: Clinical guidelines in the UK and elsewhere do not specifically address hybrid closed loop (HCL) use in the postpartum period when the demands of caring for a newborn are paramount. Our aim was to evaluate the safety and efficacy of HCL use during the first 6 months postpartum compared with standard care.
Methods: In this prespecified extension to a multicentre, randomised controlled trial, pregnant women with type 1 diabetes at nine UK sites were followed up for 6 months postpartum.

Background: Lenacapavir, a novel HIV-1 capsid inhibitor, shows promise for treating MDR HIV-1, as well as for pre-exposure prophylaxis (PrEP) in prevention of HIV infection. Its unique mechanism and lack of cross-resistance with other antiretroviral classes make lenacapavir a significant addition to HIV therapy. The clinical trials CALIBRATE and CAPELLA have demonstrated high viral suppression rates in both ART-naive individuals and individuals with MDR HIV-1.

The polar bear () is the only Arctic land mammal that dives into water to hunt. Despite thermal insulation provided by blubber and fur layers and low Arctic temperatures, their fur is typically observed to be free of ice. This study investigates the anti-icing properties of polar bear fur.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.
