Objective: The purpose of our study was to determine the folate status of pregnant women at labor, and to detect probable relationships with the gestational age at delivery, the birth weight of the newborns, as well as the mode of the delivery, taking into account any changes in the fetal heart rate (FHR) at labor and, subsequently, operative delivery.
Methods: Maternal serum folate levels were determined using automated fluorometric enzyme-linked assays. Gestational age was determined by ultrasound in the first trimester followed by serial fetal biometry.
Results: The results of our study in 101 consecutive pregnant women revealed that the mean (+/-SD) maternal serum concentration of the folate during labor was 12.01 (+/-4.16) ng/ml (range 2.50-23). The mean (+/-SD) gestational age at labor was 38.5 (+/-1.2) weeks (range 35-41 wks) as also the mean (+/-SD) birth weight of the newborns was 3.217 (+/-403) g (range 2,000-4,250 g).
Conclusions: No significant correlation (p>0.05) between folate levels of the maternal serum and gestational age at delivery or birth weight was found. The mode of delivery as a result of probable relationship between operative delivery and maternal serum folate levels was also not found.

The effect of STI screening during pregnancy on vertical transmission of HIV and adverse pregnancy outcomes in South Africa: a modelling study.

Introduction: Sexually transmitted infections (STIs) in pregnancy are associated with an increased risk of vertical HIV transmission and adverse pregnancy and birth outcomes. In South Africa, syndromic management is the standard of care for STI management. We assessed the potential impact of point-of-care (POC) screening for curable STIs (Chlamydia trachomatis [CT], Trichomonas vaginalis [TV] and Neisseria gonorrhoeae [NG]) during pregnancy on vertical HIV transmission and adverse pregnancy and birth outcomes.

In addition to biological factors, maternal exposures during pregnancy can contribute to leukemogenesis in offspring. We conducted a population-based cohort study in Sweden to investigate the association between risk of acute lymphoblastic leukemia (ALL) in offspring and maternal anthropometrics during pregnancy. A total of 2,961,435 live-born singletons during 1983-2018 were followed from birth to ALL diagnosis, end of age 18, or end of 2018.

Objective: To evaluate whether, in late pregnancy, the cerebral Doppler can identify very small fetuses that are less likely to experience intrapartum compromise (IC).
Material And Methods: This was a retrospective study of 282 singleton pregnancies that underwent an ultrasound scan at 32 + 0- 40 + 6 weeks and were delivered after induction, or spontaneous onset of labor. Very small fetuses were defined as fetuses with estimated weight less than the 3rd centile.
Prenatal ultrasound for the diagnosis of the cerebellar abnormalities: a meta-analysis.

Objective: Fetal cerebellar abnormalities are associated with neurodevelopmental disorders and structural brain malformations. Accurate and early diagnosis is crucial for prenatal counseling and planning postnatal interventions. While prenatal ultrasound is a key tool for detecting fetal brain abnormalities, variations in diagnostic accuracy across studies necessitate a systematic evaluation of its effectiveness in diagnosing cerebellar abnormalities.

Additionally, we sought to determine whether there are differences in clinical or demographic factors associated with this delayed cohort compared to those seen in infants detected early.
Methods: Newborn screen (NBS) results were collected for all cases of CH diagnosed between 2012-2022.
