Background: Dihydroartemsinin-piperaquine is highly efficacious as intermittent preventive therapy for malaria during pregnancy (IPTp). Determining associations between piperaquine exposure, malaria risk, and adverse birth outcomes informs optimal dosing strategies. Methods: HIV-uninfected pregnant women were enrolled in a placebo-controlled trial of IPTp at 12-20 weeks gestation and randomized to: sulfadoxine-pyrimethamine every 8 weeks (n=106), dihydroartemsinin-piperaquine every 8 weeks (n=94), or dihydroartemsinin-piperaquine every 4 weeks (n=100) during pregnancy...

Vaginal birth after caesarean (VBAC) delivery remains a controversial topic, and one for which there is a lack of robust data to guide clinicians and parturients regarding their best option for mode of delivery in a subsequent pregnancy. In many developed countries the trend observed in recent years is that of progressively reduced VBAC rates, and hence increased use of elective repeat caesarean section (ERCS). This factor has contributed, more than any other, to the disproportionately high caesarean section (CS) rates in many countries...

BACKGROUND: The endogenous glucocorticosteroid cortisol (F) and its metabolite cortisone (E) are known to be involved in stress adaption and anti-inflammatory and immune regulatory effects. The ratios of F to E in the matrices serum, hair and saliva are different. The shift of this ratio by the enzyme activity of 11β-hydroxysteroid-dehydrogenase, which inactivates cortisol, was often discussed. The aim of our study was to calculate the contribution of the plasma protein binding (PPB) to this shift...

Infection with Trypanosoma cruzi in women at reproductive age is associated with congenital transmission and adverse pregnancy outcome. The placenta is a key barrier to infection. We characterized gene expression profiles of term placental environment from T. cruzi seropositive (SP) and seronegative (SN) mothers performing RNA-seq. Nine pools of placental RNA paired samples were used: three from SN and six from SP tissues. Each pool consisted of female/male newborns and vaginal/caesarean deliveries binomials...

OBJECTIVE: To determine obstetric, intrapartum and perinatal outcomes for pregnancies with isolated fetal congenital heart defects (CHD). METHODS: This was a retrospective cohort study of women that delivered an infant with an isolated major CHD between January 2010 and April 2017 at a major Australian perinatal centre. The study cohort was compared with a cohort of women with infants without CHD. Cardiac abnormalities were broadly subdivided into the following five categories using the International Classification of Diseases Tenth Revision (ICD-10) as a guide - transposition of the great arteries (TGA), septal defects, right heart lesions (RHL), left heart lesions (LHL) and "other"...

BACKGROUND: Recent increases in reported congenital syphilis have led to an urgent need to identify interventions that will have the greatest impact on congenital syphilis prevention. We sought to create a congenital syphilis prevention cascade using national syphilis surveillance data to (1) estimate the proportion of potential congenital syphilis cases averted with current prevention efforts, and (2) develop a classification framework to better describe why reported cases were not averted...

Studies on pregnancy and birth outcomes in women with psoriasis are scarce and the findings inconsistent. The effect of maternal psoriasis and its severity on the risk of adverse pregnancy and birth outcomes was examined. A cross-national population-based cohort study was performed using prospectively collected data from Denmark and Sweden. Singleton births in women with psoriasis were identified in the national health registers between April 2007 and December 2012 and classified according to disease severity...

We report a case of decidual perivascular non-necrotizing granulomas in a placenta from a pregnancy complicated by severe preeclampsia with no evidence of infection. The mother was a 20-year-old primigravida with severe preeclampsia diagnosed in the third trimester with subsequent delivery of a healthy baby boy at 37 weeks 5 days gestation. Pathologic examination of the placenta showed scattered non-necrotizing granulomas in decidua, often adjacent to remodeled decidual arteries without fibrinoid necrosis...

Management of hyperglycaemia is crucial during labour to improve outcomes both in the newborn and in the mother. This is particularly crucial in mothers with pregestational type 1 diabetes and in all mothers requiring insulin treatment during pregnancy. The use of antenatal steroids in mothers at risk of preterm delivery complicates management of hyperglycaemia in the immediate antepartum period and requires appropriate dosing adjustments of insulin therapy. Mothers are generally asked to be nil per orum during active labour...

Fibroid in pregnancy is common in clinical obstetric practice.There are conflicting reports in the literature on many so-called fibroid complications in pregnancy, and there are inadequate data on the optimum management strategy. We present a case of a pregnancy with large fibroid which was uneventful till delivery but ended in immediate postpartum complication of fibroid degenerating and prolapsing into vagina dealt with myomectomy at day 30 postnatal. Initially managed conservatively with intrauterine balloon tamponade and anaemia correction and discharged home...

The emergence of microRNA as regulators of organogenesis and tissue differentiation has stimulated interest in the ablation of microRNA expression and function during discrete periods of development. To this end, inducible, conditional modulation of microRNA expression with doxycycline-based tetracycline-controlled transactivator and tamoxifen-based estrogen receptor systems has found widespread use. However, the induction agents and components of genome recombination systems negatively impact pregnancy, parturition, and post natal development; thereby limiting the use of these technologies between late gestation and the early post-natal period...

BACKGROUND: Meconium is formed before birth and may reflect the microbiome of the fetus. To test our hypothesis, we investigated whether maternal factors during pregnancy, such as biodiversity of the living environment, influence the microbiome of the first stool more than immediate perinatal factors. METHODS: We recruited 218 consecutive newborn infants from one hospital. Regions of the bacterial 16S rRNA gene were sequenced to characterize the microbiomes of the first-pass meconium samples (N=212)...
