Psychological Impacts In Exercise Riders And Professional Jockeys Following Injury, Kelley M. Renner

Theses and Dissertations--Kinesiology and Health Promotion

One of the most well-known equestrian sports, horse racing, is not only a cornerstone of Kentucky’s economy, but also a vital part of its culture, with professional jockeys playing an essential role in the local communities and traditions that define the state. Despite its popularity and financial impact, mental health challenges within the sport have continually been shrouded in silence and ignored in research (Ball et al., 2007). Equally concerning is the high injury prevalence, and psychological impact of these injuries (e.g., psychological distress, depression, anxiety, loss of identity, and self-esteem (King et al., 2022; Losty et al., 2019; McConn-Palfreyman …

Exploring Laurier Health Sciences Students’ Knowledge Of Lgbtq+ Health, Grace Emma Henry, Todd Coleman

Theses and Dissertations (Comprehensive)

In all health-related fields, the need for well-informed, holistic healthcare providers is paramount. For the heathcare field to be impactful in positive ways, providers should emerge from multifaceted academic backgrounds, equipped with an array of knowledge and skills to address the complex needs of different patients. Central to this is the idea that all aspects of an individual's identity and the intersectionality of these identities should be considered when providing care. Intersectionality recognizes that various social and personal identities, such as race, gender, sexuality, and socioeconomic status, intersect to shape individual experiences and health outcomes (Kelly et al., 2022).

Preventing Chemical And Biological Attacks: Enhanced Threats Requiring Enhanced Solutions, Alex Elliot Ottoni-Belval

Graduate Theses/Dissertations

Chemical weapons (CW) and biological weapons (BW) are becoming more dangerous for experts to employ and more accessible to amateurs. Despite CW and BW attacks throughout history that killed and maimed millions of people, the international community has failed to establish meaningful consequences to prevent them. Agreements such as the Chemical Weapons Convention and the Biological Weapons Convention vow to eliminate and reduce the effects of CWs and BWs but lack respected response precedents and capabilities. The limited and inconsistent enforcement has inadvertently allowed CWs and BWs to become plausible weapons, especially to gain asymmetric advantages, while modern developments exasperate …

Timing Of Delivery In Preeclampsia: Time To Reconsider?, Rebecca Horgan, Ahmed S. Z. Moustafa, Mackenzie Mchugh, Tetsuya Kawakita, Baha Sibai, George Saade

Department of Obstetrics & Gynecology Faculty Publications

The article discusses the need to reassess the timing of delivery in cases of preeclampsia, a condition affecting 2%–8% of pregnancies and linked to significant maternal and neonatal risks. It highlights that existing guidelines, primarily based on older studies, may not adequately reflect current clinical practices and advancements in neonatal care. The authors suggest that planned delivery at 34–36 weeks of gestation may offer maternal benefits without increasing short-term neonatal morbidity, while also emphasizing the importance of considering long-term outcomes for both mothers and infants. They advocate for further research, including large-scale randomized trials, to better understand the implications of …

Effectiveness And Safety Of Intravenous Iron Therapy In Outpatient Obstetrical Clinic For Treatment Of Iron-Deficiency Anemia During Pregnancy, Ellen M. Murrin, Olivia S. Lebeau, Lillian Singer, Mark A. Kassab, Peyton Kalan, Julie Costanzo, Scott A. Sullivan, George L. Maxwell, George R. Saade, Antonio F. Saad

Department of Obstetrics & Gynecology Faculty Publications

Background

Iron-deficiency anemia (IDA) affects over one-third of pregnant patients globally, contributing to severe maternal morbidity and adverse neonatal outcomes. Oral iron supplementation, while cost-effective, is limited by poor absorption, significant gastrointestinal side effects, and poor adherence. The use of intravenous (IV) iron addresses many of these concerns, including eliminating GI side effects and the need for daily therapy. However, administration of IV iron in pregnant patients is typically restricted to specialized infusion centers or hospitals due to concerns about acute side effects, cost, resource utilization, the need for fetal heart rate monitoring, and extended infusion times.

Methods

This descriptive …

Reply [To Burnout Reflections: Musings On Bianchi And Schonfeld’S Five Focal Areas], Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

Contrary to what one might assume, the burnout construct did not emerge from systematic research. The definition of burnout was formulated in the 1970s based on prenotions and anecdotal evidence. No sound empirical studies, no in-depth theoretical reflections, not even a review of the stress literature underpinned the introduction of the construct. It is thus unsurprising that some observers regard the edifice of burnout research with scepticism. The pioneers of burnout research neglected basic scientific standards and, by overlooking the abundant work of contemporary stress researchers, deprived themselves of important safeguards against illusions of novelty making big claims based on …
