Purpose: In vitro fertilization (IVF) has been a well-established method for treating infertility for over four decades. The mainstay method of culture of oocytes and embryos has been in gas incubators. More recently, the novel use of a gas-permeable closed vessel to culture oocytes and embryos in the vagina, intravaginal culture (IVC), has been introduced as a viable lower-cost option for infertility patients. Several studies have studied the efficacy of IVC; however, there is no data on the perinatal outcomes of the babies born using this newer technology.
Methods: Our study is a retrospective case series (n = 66) from a single center, uniquely examining the perinatal outcomes of infants born after IVC.
Results: There were 50 singleton and 16 twin gestations in this case series. For singleton infants conceived via IVC (n = 50), the mean gestational age at delivery was 38 weeks and 4 days, and the mean birth weight was 3159.1 + / - 501.5 g. Four infants were born with low birth weight, three were born preterm, and one was born macrosomic. The twin pregnancies had a mean gestational age at delivery of 33 weeks 4 days and a mean birth weight of 1992.9 + / - 620.7 g. Twenty-seven infants met the criteria for low birthweight, and twenty-four infants delivered preterm. No twin infants met the criteria for macrosomia.
Conclusion: This case series provides an initial description of the perinatal outcomes of IVC conceived infants, which shows no concerning trends in adverse birth outcomes for singleton infants. As expected, IVC twin gestations had a high rate of low birth weight and preterm delivery. Continued larger studies are essential to provide more comprehensive data on perinatal outcomes of infants conceived by this new technology.

Background: Adverse birth outcomes (ABO), such as preterm birth (PTB), small and large for gestational age (SGA/LGA), can compromise both the short- and long-term health of mothers and their foetuses. The purpose of this observational study was to investigate the association between maternal serum alkaline phosphatase (ALP) levels in late pregnancy and the risk of ABO, and to evaluate its predictive value of maternal ALP levels for ABO in women with singleton pregnancies.
Methods: A total of 11 853 consecutive pregnant women underwent hepatic and renal function tests, lipid profile assessments, ALP and high-sensitivity C-reactive protein levels measurements upon admission for labour.
Unveiling the potential role of the shock index in maternal sepsis: reality or fantasy?

Objective: Maternal sepsis continues to be a maternal health problem associated with 75,000 deaths per year worldwide, representing a greater burden in low- and middle-income countries (LMICs). Although the Shock Index (SI) has been widely studied in postpartum hemorrhage and in non-obstetric populations, it has not yet been widely studied in sepsis. We aimed to identify the relationship between Shock Index and suspected sepsis in pregnant and postpartum patients to explore the use of Shock index in the context of maternal sepsis and its relationship with sepsis-related outcomes.

Background: The World Health Organization (WHO) recommends antiretroviral therapy (ART) containing two nucleoside reverse transcriptase inhibitors (NRTIs) as backbone. WHO recommends tenofovir disoproxil fumarate combined with lamivudine or emtricitabine as first line in pregnancy, and zidovudine, abacavir or tenofovir alafenamide, combined with lamivudine or emtricitabine, as alternatives.
Objectives: Evaluate risk of adverse perinatal outcomes in pregnant women living with HIV (WLHIV) receiving different NRTIs.
The combined effects of omega-3 polyunsaturated fatty acid supplementation and exercise training on body composition and cardiometabolic health in adults: a systematic review and meta-analysis.

Introduction: We performed a systematic review and meta-analysis to investigate the effects of combining omega-3 polyunsaturated fatty acids (n-3 PUFAs) supplementation with exercise training, as compared to exercise training alone, on body composition measures including body weight, body mass index (BMI), fat mass, body fat percentage, and lean body mass. Additionally, we determined the effects on cardiometabolic health outcomes including lipid profiles, blood pressure, glycemic markers, and inflammatory markers.
Method: Three primary electronic databases including PubMed, Web of Science, and Scopus were searched from inception to April 5, 2023 to identify original articles comparing n-3 PUFA supplementation plus exercise training versus exercise training alone, that investigated at least one of the following outcomes: fat mass, body fat percentage, lean body mass, triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), systolic (SBP) and diastolic (DBP) blood pressures, fasting glucose and insulin, interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α).

Purpose: To examine associations between COVID-19 pandemic and maternal SARS-CoV-2 infection with perinatal outcomes.
Methods: We conducted a retrospective cohort study of 189,097 singleton births in South Carolina (2018-2021). Pregnancy timing relative to the pandemic was classified as pre-pandemic (delivered before March 1, 2020), partial pandemic overlap (conceived before and delivered during the pandemic), or pandemic (conceived and delivered during the pandemic).
