Jaffer, Manorama Purwar, Fernando C. Barros, Leila Cheikh Ismail, Wu Qingqing, Ilaria Stura, Maria Carvalho

Obstetrics and Gynaecology, East Africa

Assessing the size of twins at birth using charts developed for singletons may over diagnose small for gestational age in this sub-population. The study aimed to produce international, twin-specific, newborn size normative charts by gestational age and sex. This longitudinal observational study in eight geographically diverse settings prospectively collected data between May 2009 and August 2013 from healthy pregnant women and their newborn twins. The participants were enrolled as part of the INTERGROWTH-21st study, and recruited based on World Health Organization recommendations for evaluation of anthropometric measures. All the women met, in addition to the underlying population characteristics of low …

Normative Growth Trajectories Of Fetal Brain Regions Validated By Satisfactory Maturation Of Neurodevelopmental Domains At 2 Years Of Age, Madeleine Wyburd, Stephen Kennedy, Michelle Fernandes, Nicola Dinsdale, Linde Hesse, Robert Gunier, Leila Ismail, Eric Ohuma, Michael Gravett, Maria Carvalho

Obstetrics and Gynaecology, East Africa

We previously constructed a qualitative, 3D ultrasound derived atlas of the normative spatiotemporal dynamics of fetal brain maturation. Here, using the same healthy multi-national cohort, we applied deep learning methods to 4205 fetal brain scans from 18–27 weeks’ gestation, to produce an extensive, quantitative description of the growth of 16 fetal brain structures associated with satisfactory domain-specific neurodevelopmental scores at 2 years of age. The methodology, which is publicly available, takes less than 10 seconds per scan. We define 28 region-specific, functionally relevant, normative growth trajectories, a ratio between the relative volumes of the insular (rILV) and parietal (rPLV) lobes …

The Use Of A Standardized Checklist For Image Acquisition: An Obstetric Ultrasound Quality Improvement Study, Ingrid Gichere, Nidhi Leekha, Sikolia Wanyonyi

Obstetrics and Gynaecology, East Africa

Introduction A complete anatomical survey during the mid-trimester ultrasound is critical for detecting fetal anomalies. In sub-Saharan Africa, detection rates remain low, contributing to a significant disease burden. This study evaluated whether implementing a standardized electronic checklist, based on existing guidelines, would improve image acquisition.

Methods We carried out a pre- and post-intervention quasi-experimental quality improvement study. An electronic checklist replaced the previous ultrasound report template. A baseline review involved 385 mid-trimester scans conducted between November 2022 and December 2023. Following checklist implementation and targeted sonographer training, 238 scans were reassessed from July to December 2024. The image acquisition rate …

In this study, we used a cross-sectional descriptive qualitative study to explore the attitudes, beliefs, and behaviors related to COVID-19 vaccination during pregnancy in Kenya. A total of 50 in-depth interviews were conducted between October 2023 to March 2024 with a purposively drawn sample of 25 pregnant and 25 postpartum women during …

Policy, Misinformation, And Mortality: The Effects Of Abortion Restrictions On Maternal Outcomes, Gabrielle Samiratedu Dmsc, Mcms, Pa-C

Lynchburg Journal of Medical Science

The objective of this review is to evaluate the effects of restrictive abortion laws on maternal mortality and morbidity in the United States. Even before the landmark reversal of Roe v. Wade, the US had one of the highest maternal mortality rates among other high-income countries, and rates are expected to continue to rise in states with restrictive abortion policies. Electronic databases and public health data were analyzed to assess clinical outcomes, access to care, and disparities associated with abortion restrictions nationally and internationally. The findings suggest that states with highly restrictive abortion policies experience higher rates of maternal morbidity …

Association Of Short Interpregnancy Interval Among Multigravid “Pregnant Youth” In A Tertiary Hospital, Eileen Feliz Cortes-Garcia

The Lasallian Journal of Health

Introduction: Pregnancy among the youth is in creasing not only in the Philippines but worldwide. Studies have shown that a short interpregnancy inter val of 18 months or less is associated with an in creased risk of fetal and maternal complications. However, limited data are available regarding fetal and maternal outcomes among pregnant youth with short interpregnancy intervals, particularly in the Philippines. Objectives: The objective of the study was to deter mine the association between a short interpregnancy interval of <18 months and adverse fetomaternal out comes among pregnant youth aged 15 to 24 years who had their first pregnancy at De La Salle Univer sity Medical Center (DLSUMC) from 2017 to 2019. Methods: This was a retrospective cohort study in volving 130 participants who delivered at DLSUMC from 2017 to 2019 either by vaginal spontaneous delivery, assisted vaginal delivery, or cesarean sec tion. Results: Of these, 84 (66.15%) were 22 to 24 years old and the majority had their first pregnancy at the age of 18 to 21 years (59 [45.38%]). This study demonstrated that preterm delivery, postpartum hem orrhage, and hypertension were significantly associ ated with a short interpregnancy interval. Conclusions: Short interpregnancy interval is associ ated with an increased risk of preterm delivery, hy pertension, and postpartum hemorrhage among mul tiparous pregnant youth. Counseling and proper edu cation, including family planning, are important for both maternal and fetal health. The use of different family planning methods should be discussed and made accessible to young women.

Advancing Screening For Intimate Partner Violence In Pregnant Individuals Throughout The Perinatal Period To Prevent Adverse Pregnancy And Maternal Outcomes, Emilia R. Valdez

Nursing | Senior Theses

Background: Intimate Partner Violence experienced by pregnant individuals contributes to adverse pregnancy outcomes and maternal health. A mother’s exposure to Intimate Partner Violence (IPV) can affect their ability to carry a healthy pregnancy to term (38 – 40 weeks gestational age) and places them at risk for comorbidities including; Preterm birth, Intrauterine Growth Restriction, Low Birth Weight/ Small for Gestational Age, Premature Rupture of Membranes and Miscarriage. The incidence of IPV screening is not accessible to all pregnant individuals due to healthcare providers lack of education, time constraints in the workplace, bias and discomfort towards IPV. The implementation of IPV …

Massive Subcutaneous Emphysema Following Robot-Assisted Total Laparoscopic Hysterectomy: A Case Report, Alia Valdez, Isabella Sciacca, Charmaine Oladell

North Texas GME Research Forum 2026

Background Subcutaneous emphysema is the presence of air within subcutaneous tissues, often presenting as swelling and palpable crepitus. Air may spread along fascial planes and arise from traumatic, iatrogenic, infectious, or spontaneous sources. In laparoscopic surgery, it is most commonly related to carbon dioxide insufflation. Reported incidence following laparoscopic procedures ranges from 2% to 24%, depending on procedure type, surgical duration, insufflation pressure, and patient factors. In gynecologic laparoscopy, incidence has been reported as low as 2.3% in some studies, with rates up to 10–15% in others, particularly with higher intraabdominal pressures. Although often benign, extensive subcutaneous emphysema may lead …
