Methods We present a case of a 34-year-old pregnant woman who, after discontinuing 3DR due to side effects and poor adherence, was switched to DTG/3TC at gestational week 23. Maternal viral load (VL) and infant HIV status were monitored throughout pregnancy and a ten-month breastfeeding period. Data on pharmacokinetic changes in pregnancy and the risks associated with 2DR were reviewed. Results The patient’s VL remained suppressed (<20 copies/mL) from gestational week 23 until the end of the breastfeeding period. A healthy HIV-negative baby was born at 39 weeks, and the child remained HIV-negative after ten months of breastfeeding. The 2DR was well-tolerated, improved adherence, and reduced fetal drug exposure. Despite limited experience with 2DR in pregnancy, no viral rebound occurred, and no adverse effects were observed. Conclusions Although 3DR remains the preferred therapy during pregnancy and breastfeeding, this case indicates that DTG/3TC may be an effective alternative for patients experiencing intolerance or poor adherence to 3DR.

ObGyns significantly impact societal health through their care for pregnant women, fetuses, and newborns, uniquely positioning them to advocate for health initiatives with lasting societal benefits. Despite its importance, the history of medicine is underrepresented in medical curricula, missing opportunities to foster critical thinking and ethical decision-making. In today’s climate of threatened reproductive rights, vaccine misinformation, and harmful ideologies, it is imperative for ObGyns to champion comprehensive historical education. The history of medicine, particularly in relation to societal issues – such as racism, discrimination, genocides, pandemics, and wars – provides valuable context for addressing challenges like maternal mortality, reproductive rights, vaccine hesitancy, and ethical issues. Understanding historical milestones and notable ethical breaches, such as the Tuskegee Study and the thalidomide tragedy, informs better practices and safeguards patient rights. Technological advancements in hygiene, antibiotics, vaccines, and prenatal care have revolutionized the field, yet contemporary ObGyns must remain vigilant about lessons learned from past challenges and successes. Integrating historical knowledge into medical training enhances clinical proficiency and ethical responsibility, fostering innovation and improving health outcomes. By reflecting on historical achievements and their impacts, current and future ObGyns can advance the field, ensuring comprehensive and ethically sound approaches to patient care. This paper highlights the crucial role of historical knowledge in shaping modern ObGyn practices, advocating for its integration into medical education to address contemporary health challenges and ethical considerations.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":"1 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to compare different echocardiographic markers in recent cohort of newborn infants with and without PPHN. Methods In this retrospective study, common echocardiographic markers were examined in infants>34 weeks’ gestation with PPHN (cases) and without PPHN (controls). Infants with congenital heart disease were excluded. Binary regression testing was used to evaluate echocardiographic markers predicting PPHN and death. In addition, diagnostic accuracy testing of echocardiographic markers using ROC was also performed. Intra-observer reliability for echocardiographic markers was examined using coefficient of variation (CoV) and intraclass correlation. Results Fifty-two infants were studied; 22 (42 %) infants with PPHN had significantly higher oxygen requirement, oxygenation index and ventilation days when compared with controls. Echocardiographic markers such as TR Vmax, S/D TR, PAAT, TAPSE and eccentricity index (EI) were significantly different between cases and controls. Receiver operator characteristics analysis of echocardiographic markers revealed TR Vmax 0.96 (0.9–1.0), S/D TR 0.95 (0.87–1.0) and end systolic EI 0.94 (0.87–1.0).
