Placental Malaria and Its Relationship with Neonatal Birth Weight among Primigravidae: An Analytical Cross-sectional Study.

Background And Objectives: Malaria can be fatal during pregnancy, posing a serious risk to both mothers and fetuses, especially in sub-Saharan Africa. Primigravidae are particularly susceptible to placental malaria in areas with high rates of transmission due to insufficient immunity. This study aimed to determine the prevalence of placental malaria infection, risk factors, types of Plasmodium causing malaria during pregnancy, and its relationship with neonatal birth weight among primigravidae.

Lipid and glucose profiles in pregnant women with HIV on tenofovir-based antiretroviral therapy.

Objective: Tenofovir alafenamide (TAF)-based antiretroviral therapy (ART) regimens have been associated with adverse changes in lipid and glucose profiles compared with tenofovir disoproxil fumarate (TDF)-based ART, but data in pregnancy is limited. We evaluated metabolic markers in pregnant women with HIV after starting TAF- vs TDF-based ART.

Methods: We analyzed data within the IMPAACT 2010/VESTED trial, which demonstrated better pregnancy outcomes in pregnant women randomized to initiate TAF/Emtricitabine/Dolutegravir (TAF/FTC+DTG; n=217) or TDF/FTC+DTG (n=215).

Pharmacokinetics and Safety of Remdesivir in Pregnant and Nonpregnant Women With COVID-19: Results From IMPAACT 2032.

Background: Pregnant people with coronavirus disease 2019 (COVID-19) experience higher risk for severe disease and adverse pregnancy outcomes, but no pharmacokinetic (PK) data exist to support dosing of COVID-19 therapeutics during pregnancy. We report PK and safety data for intravenous remdesivir in pregnancy.

Methods: IMPAACT 2032 was a phase 4 prospective, open-label, nonrandomized opportunistic study of hospitalized pregnant and nonpregnant women receiving intravenous remdesivir as part of clinical care.

Trends and Outcomes of Twin Births in Southwest Nigeria: A 14-Year Retrospective Cohort Study.

Background And Objectives: The study aimed to analyze the prevalence, trends, and outcomes of twin pregnancies in Ile-Ife, Nigeria, over two distinct periods.

Materials And Methods: This research, based on a 14-year retrospective cohort study, scrutinized twin births occurring in two-time frames: recent years (2012-2018; Period II) and the recent past (2005-2011; Period I) at a University Teaching Hospital in Ile-Ife, Nigeria. The inclusion criteria were limited to twin births, excluding singleton and higher-order gestations.

Neutrophil Elastase as a Predictor of Delivery in Pregnant Women with Preterm Labour.

Background And Objectives: No previous study has been conducted in Nigeria on the role of neutrophil elastase in predicting preterm birth. The present study aimed to determine the role of the neutrophil elastase test in predicting birth in women with preterm labor.

Methods: The present prospective cohort study recruited 83 pregnant women with preterm labor between 28 and 36 weeks of gestation, and followed up these subjects for 14 days.

Prophylactic tranexamic acid for reducing intraoperative blood loss during cesarean section in women at high risk of postpartum hemorrhage: A double-blind placebo randomized controlled trial.

Background: Postpartum hemorrhage remains a leading cause of maternal mortality especially in developing countries. The majority of previous trials on the effectiveness of tranexamic acid in reducing blood loss were performed in low-risk women for postpartum hemorrhage. A recent Cochrane Systematic Review recommended that further research was needed to determine the effects of prophylactic tranexamic acid for preventing intraoperative blood loss in women at high risk of postpartum hemorrhage.

Blood pressure thresholds for the diagnosis of hypertensive disorders of pregnancy in sickle cell disease.

In this retrospective cohort study of singleton pregnancies in people with sickle cell disease (SCD) delivered at two academic centres between 1990 and 2021, we collected demographic and SCD-related data, pregnancy outcomes, and the highest systolic and diastolic blood pressure (SBP and DBP) at seven time periods. We compared the characteristics of subjects with new or worsening proteinuria (NWP) during pregnancy to those without. We then constructed receiver operating characteristic (ROC) curves to determine the blood pressure (BP) that best identifies those with NWP.

Maternal and umbilical cord blood levels of leptin in pre-eclamptic and healthy pregnant women: A comparative cross-sectional study.

Background: Pre-eclampsia is a multi-systemic disease with its attendant increased maternal and perinatal morbidities and mortality. It has been hypothesized that leptin contributes immensely to the natural history of pre-eclampsia. However, there is considerable disagreement in the reports of existing research work on the link between fetomaternal serum leptin levels and pre-eclampsia.

Obstetric Outcome of Induction of Labour in a Tertiary Hospital in Nigeria: A Five-Year Retrospective Cross-Sectional Study.

Background: Induction of labour has remained one of the most valuable interventions in obstetric practice. Over the years, the proportion of women undergoing induction of labour (IOL) has been on a steady increase. The significance to obstetrics practice as well as its maternal and perinatal outcomes are sacrosanct, hence the need for its periodic review.

The impact of COVID-19 on the birth rate in Nigeria: a report from population-based registries.

Background And Objectives: Coronavirus disease 2019 (COVID-19) is a pandemic that has become a major source of morbidity and mortality worldwide, affecting the physical and mental health of individuals influencing reproduction. Despite the threat, it poses to maternal health in sub-Saharan Africa and Nigeria, there is little or no data on the impact it has on fertility, conception, gestation and birth. To compare the birth rate between pre-COVID and COVID times using selected months of the year.

Pharmacokinetics and safety of first-line tuberculosis drugs rifampin, isoniazid, ethambutol, and pyrazinamide during pregnancy and postpartum: results from IMPAACT P1026s.

Physiological changes during pregnancy may alter the pharmacokinetics (PK) of antituberculosis drugs. The International Maternal Pediatric Adolescent AIDS Clinical Trials Network P1026s was a multicenter, phase IV, observational, prospective PK and safety study of antiretroviral and antituberculosis drugs administered as part of clinical care in pregnant persons living with and without HIV. We assessed the effects of pregnancy on rifampin, isoniazid, ethambutol, and pyrazinamide PK in pregnant and postpartum (PP) persons without HIV treated for drug-susceptible tuberculosis disease.

Natural history of blood pressure in sickle cell disease pregnancy.

In this retrospective cohort study of singleton pregnancies in people with sickle cell disease (SCD) delivered at two academic centres between 1990 and 2021, we collected demographic and SCD-related data, pregnancy outcomes, and the highest systolic and diastolic blood pressure (SBP and DBP) at seven time periods. We compared blood pressure values and trajectories in the composite cohort and in each genotype group to control values in a non-SCD pregnancy dataset. There were 290 pregnancies among 197 patients with SCD.

Reduction in preterm birth among COVID-19-vaccinated pregnant individuals in the United States.

Background: Most studies investigating preterm birth and COVID-19 vaccination have suggested no difference in preterm birth rates between vaccinated and unvaccinated pregnant individuals; however, 1 recent study suggested a protective effect of COVID-19 vaccination on preterm birth rates in Australia.

Objective: This study aimed to determine whether a similar association and protective effect of COVID-19 vaccination on preterm birth would be found in our multistate, US cohort.

Study Design: A cohort study was conducted using the Vizient Clinical Database, which included data from 192 hospitals in 38 states.

The relationship between COVID-19 vaccination status in pregnancy and birthweight.

Background: Despite findings that maternal COVID-19 infection in pregnancy is associated with low birthweight (weight of ≤2500 g), previous studies demonstrate no difference in low birthweight risk between COVID-19 vaccinated and unvaccinated pregnant persons. Few studies, however, have examined the association between unvaccinated, incomplete vaccination, and complete vaccination on low birthweight, and they have been limited by small sample sizes and lack of adjustment for covariates.

Objective: We sought to address key limitations of prior work and evaluate this association between unvaccinated, incomplete, and complete COVID-19 vaccination status in pregnancy and low birthweight.

Physiologic Changes During Pregnancy and Impact on Small-Molecule Drugs, Biologic (Monoclonal Antibody) Disposition, and Response.

Pregnancy is a unique physiological state that results in many changes in bodily function, including cellular, metabolic, and hormonal changes. These changes can have a significant impact on the way small-molecule drugs and monoclonal antibodies (biologics) function and are metabolized, including efficacy, safety, potency, and adverse effects. In this article, we review the various physiologic changes that occur during pregnancy and their effects on drug and biologic metabolism, including changes in the coagulation, gastrointestinal, renal, endocrine, hepatic, respiratory, and cardiovascular systems.

A Five-Year Review of Feto-Maternal Outcome of Antepartum Haemorrhage in a Tertiary Center.

Background: Pregnancies complicated with antepartum-haemorrhage is high risk pregnancies associated with adverse maternal, fetal-and-perinatal-outcomes. It contributes significantly to fetal and maternal mortality especially in the developing countries. Proper antenatal care and prompt intervention is necessary to forestall adverse and improve outcome.
