Overall, 2,733 of 24,213 individuals (11.3%) received the vaccine. Vaccine receipt was associated with lower odds of preterm birth (5.5% vaccinated group vs 6.8% unvaccinated group, adjusted odds ratio 0.80, 95% CI, 0.67–0.95). Receipt of the RSV vaccine was not associated with any …

Examining The Relationship Between A Positive Obstructive Sleep Apnea Diagnosis And Referring Symptoms Of The Pregnant Patient, Christina Emerson, Beth Tremblay

Knowledge and Creativity Expo

PROBLEM: Many healthcare providers do not routinely screen pregnant individuals for obstructive sleep apnea (OSA), contributing to its underdiagnosis and potentially leading to various pregnancy-related health issues. Currently used OSA screening tools, such as the Berlin Questionnaire, STOP-BANG Questionnaire, and Epworth Sleepiness Scale, often demonstrate poor predictive value in pregnant women due to the dynamic physiological changes of pregnancy and the differing presentation of OSA in this population.

PURPOSE: To examine the relationships between a positive OSA diagnosis, patient characteristics, and the symptoms among pregnant patients referred for sleep studies.

EBP QUESTIONS: 1) Is there a relationship between certain referring …

While de novo variants cause many Mendelian disorders, their detection currently requires sequencing of the proband and both biological parents. This is not feasible when only one parent is available, a limitation for millions of families. Here, we develop duoNovo, which identifies de novo variants from parent-proband duos using long-read sequencing followed by haplotype reconstruction and detection of identical-by-descent haplotype blocks. We sequenced 104 trios with PacBio HiFi sequencing and applied duoNovo to each of the 208 duos constructed by masking one parent, classifying over 55 million variants according to their de novo status. We evaluated duoNovo's performance against classifications …

Exploring Physician Views On Birth Method And Route Of Delivery, Vivian Nguyen, Vincenzo Berghella, Md

Alpha Omega Alpha Research Symposium Posters

Purpose: In the United States, rates of cesarean deliveries (CD) have been increasing. Despite recommendations from the American College of Obstetrics and Gynecology to prevent increasing rates of CDs, planned CD has been associated with lower rates of perinatal deaths and better maternal outcomes when compared to planned vaginal delivery (VD). However, the data is limited, so it is important that we conduct randomized controlled trials (RCTs) comparing maternal and perinatal outcomes in planned CD vs planned vaginal delivery (VD) for nulliparous, term, single, vertex pregnancies. The purpose of study is to survey obstetricians and gynecologists (ob/gyns) on their …

The Hidden Link Between Endometriosis And Obesity: A State-Of-The-Art Review, Shefali N Desai, Christina C Reed, Yamely Mendez, Qiannan Yang, Xiaoming Guan

Faculty, Staff and Students Publications

Endometriosis remains an under-researched disease with a wide range of symptoms. Endometriosis reduces a woman's quality of life and professional productivity, yet its exact causes, risk factors, and treatment have yet to be elucidated. Body mass index and endometriosis have been observed to be inversely related; however, this relationship may only be a correlation rather than a causation. Obesity may play a role in the inflammation and cell proliferation associated with endometriosis through the complex signaling pathways of adipokines. A literature review was done on endometriosis and obesity to gain insight and synthesize knowledge about opportunities to improve endometriosis care, …
