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. Further studies are needed to explore the impact of pharmacokinetic changes in pregnancy on 2DR efficacy and to confirm its safety and role in preventing MTCT.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":"31 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142264508","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}

Pregnant women are vulnerable to adverse effects of medicines, especially during the first trimester. Though it is advised to avoid unnecessary intake of medicine during pregnancy, CAM use is widespread. Methods A cross-sectional questionnaire-based study was conducted on 120 pregnant women attending the antenatal clinic of a tertiary-care teaching hospital in Udaipur district of Southern Rajasthan, India. Women of age 18 years and above were surveyed between July 2022 to December 2023 by convenient sampling strategy and data were entered in a pretested and pre-validated questionnaire.

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). These markers were found to predict death in this cohort of infants. CoV and Intra-observer reliability was good for various echocardiographic markers. Conclusions Among the various echocardiographic markers studied, TR Vmax when present along with S/D TR and end systolic EI had good intra-observer reliability and were diagnostic of PPHN and predicted death in this cohort.

We also assessed the potential impact of universal screening for vasa previa on reducing stillbirth rates. Methods We utilized nationally-reported birth and stillbirth data from public databases in the United States, United Kingdom, Canada, Germany, Ireland, Greece, Sweden, Portugal, and Australia. Using the annual number of births and the number and rate of stillbirths in each country, and the published incidence of vasa previa and stillbirth rates associated with the condition, we estimated the expected annual number of cases of vasa previa, those that would result in a livebirth, and the potential preventable stillbirths with and without prenatal diagnosis. Results There were 6,099,118 total annual births with 32,550 stillbirths, corresponding to a summary stillbirth rate of 5.34 per 1,000 pregnancies. The total expected vasa previa cases was estimated to be 5,007 (95 % CI: 3,208–7,201). The estimated number of livebirths would be 4,937 (95 % CI: 3,163–7,100) and 3,610 (95 % CI: 2,313–5,192) in pregnancies with and without a prenatal diagnosis of VP. This implies that prenatal diagnosis would potentially prevent 1,327 (95 % CI: 850–1,908) stillbirths in these countries, corresponding to a potential reduction in stillbirth rate by 4.72 % (95 % CI: 3.80–5.74) if routine screening for vasa previa was performed.
