Who needs prenatal counselling with a pediatric surgeon? Experience from a large tertiary care university hospital

Objectives To describe our experience with prenatal counselling for surgical anomalies in a large volume center. The secondary aim is to suggest a list of prenatal abnormalities warranting counselling by a pediatric surgeon. Methods We reviewed all prenatal counselling consultations performed by the pediatric surgery team between January 1st, 2015 and December 31st, 2016. Results A total of 169 patients or couples had a prenatal consultation with a pediatric surgeon. Prenatal work-up included a fetal MRI in 26% of cases, mainly for digestive and thoracic pathologies (56.1% of cases). Consultation with the pediatric surgeon led mainly to recommendations concerning the place of delivery. Induction for reasons related to the fetal anomaly occurred in 22.2% of cases. Most children were surgically treated within the first year of life (63.5%). Correlation between predicted prognosis and actual status at four years of life was 96.9%. Correlation between prenatal and postnatal diagnosis was 87.4%. Conclusions Prenatal counselling by a pediatric surgeon allows couples to obtain clear information on the pathology of their unborn child, giving them greater autonomy in their decision to continue the pregnancy.

To evaluate the role of placental human papilloma virus (HPV) infection as a risk factor for spontaneous preterm birth: a prospective case control study

Objectives i) To compare the placental human papilloma virus (HPV) deoxynucleic acid (DNA) status of preterm deliveries with full term deliveries and to identify high risk (HR) genotypes (HPV 16 and 18); and ii) To compare the perinatal outcomes of HPV positive with HPV negative pregnant women. Methods A case control study was carried out on 100 antenatal women with singleton live pregnancies admitted in labor ward of a tertiary care teaching hospital from April 2017 to March 2018. The two study groups were i) spontaneous preterm deliveries between 24 and 36 + 6 weeks (n=50) and ii) full term deliveries ≥37 weeks (n=50). The placental tissue was analysed for HPV DNA and HR HPV genotypes were detected by type specific primers. A comparative analysis of perinatal outcomes between HPV positive and negative women was done. Results An overall placental tissue HPV prevalence of 12% (12/100) was observed in study cohort which was not significantly different between preterm and full term deliveries (16 vs. 8%, p=0.218). HPV 16 was significantly associated with preterm births (p=0.04). Both HPV affected and non-affected women were comparable in terms of mode of delivery and neonatal outcomes. However, a statistically significant association of preterm neonatal intensive care admissions with HR HPV 16 genotype was observed (p=0.04). Conclusions Spontaneous preterm births can be attributed to placental HPV infection, specifically HR HPV 16 genotype. This association identifies a potentially preventable cause of prematurity and its associated complications, in wake of availability of an effective vaccine.

Pregnancy outcomes with differences in grain consumption: a randomized controlled trial

Objectives Contemporary obstetrics has begun to appreciate the importance of diet in pregnancy, but guidelines are not based on robust data. The hypothesis that a whole grains diet improves pregnancy outcomes is tested in this study. We compared maternal and neonatal outcomes for a pregnancy diet containing 75% of total carbohydrates as refined grains with outcomes for a diet with 75% of total carbohydrates as whole grains. Methods This was a randomized interventional study in a clinic population over the last 4–7 months of normal pregnancy with extensive compliance measures. Besides obstetrical and neonatal outcomes, anthropometric measurements were done. In addition to food frequency questionnaires (FFQs), total plasma alkyl resorcinols, a unique quantitative measure of whole grains, were used as a measure of whole grain consumption. Results The data show effective compliance and no difference in outcomes between the diets with regard to maternal weight gain, birth weights, subcutaneous fat and glucose tolerance. Conclusions Ensuring compliance to a proper pregnancy diet resulted in satisfactory weight gain and normal outcomes even when the proportion of whole grains consumed is only 25% of total carbohydrates. www.ClinicalTrials.gov NCT03232762, Effects of Diet on Pregnancy Outcome and Child Obesity.

Rarity of fetal cells in exocervical samples for noninvasive prenatal diagnosis

Objectives The possibility to isolate fetal cells from pregnant women cervical samples has been discussed for five decades but is not currently applied in clinical practice. This study aimed at offering prenatal genetic diagnosis from fetal cells obtained through noninvasive exocervical sampling and immuno-sorted based on expression of HLA-G. Methods We first developed and validated robust protocols for cell detection and isolation on control cell lines expressing (JEG-3) or not (JAR) the HLA-G antigen, a specific marker for extravillous trophoblasts. We then applied these protocols to noninvasive exocervical samples collected from pregnant women between 6 and 14 weeks of gestational age. Sampling was performed through insertion and rotation of a brush at the ectocervix close to the external os of the endocervical canal. Finally, we attempted to detect and quantify trophoblasts in exocervical samples from pregnant women by ddPCR targeting the male SRY locus. Results For immunohistochemistry, a strong specific signal for HLA-G was observed in the positive control cell line and for rare cells in exocervical samples, but only in non-fixative conditions. HLA-G positive cells diluted in HLA-G negative cells were isolated by flow cytometry or magnetic cell sorting. However, no HLA-G positive cells could be recovered from exocervical samples. SRY gene was detected by ddPCR in exocervical samples from male (50%) but also female (27%) pregnancies. Conclusions Our data suggest that trophoblasts are too rarely and inconstantly present in noninvasive exocervical samples to be reliably retrieved by standard immunoisolation techniques and therefore cannot replace the current practice for prenatal screening and diagnosis.

Comparison of prenatal central nervous system abnormalities with postmortem findings in fetuses following termination of pregnancy and clinical utility of postmortem examination

Objectives In this study, we aimed to compare prenatal ultrasound (USG) and postmortem examination findings of central nervous system (CNS) abnormalities in fetuses following termination of pregnancy (TOP). Methods A total of 190 fetuses with USG-confirmed fetal CNS abnormalities of terminated pregnancies between January 2001 and January 2017 were retrospectively analyzed and USG and postmortem examination findings were compared. Results The most frequent CNS abnormalities were acrania/anencephaly (n=45, 24%), spina bifida (n=43, 23%), and ventriculomegaly (n=35, 18%). In 144 of the 190 (76%) cases, there was total agreement between USG and postmortem examination diagnosis. Postmortem examination provided minor findings which did not change the major clinical diagnosis in two (1%) cases with spina bifida and ventriculomegaly. In six (3%) cases, the diagnosis changed after postmortem examination. In 25 of the 190 (13%) cases with multiple abnormalities as evidenced by USG, CNS abnormality was unable to be confirmed at postmortem examination. Conclusions Our study results show an overall high agreement (76%) between USG and postmortem examination findings for CNS malformations. Due to autolysis and fluid structure, USG-confirmed CNS diagnosis cannot be always confirmed by postmortem examination. This potential discrepancy should be explained to patients before considering TOP. Postmortem examination is the gold standard to confirm prenatal diagnosis.

Maternal mortality in the city of Berlin: consequences for perinatal healthcare

Objectives The fifth of the United Nations’ Millennium Development Goals proposed for 2000–2015 was to improve maternal health, which has only partially been achieved. Worldwide, the maternal mortality ratio is currently estimated at 216/100.000 livebirths, compared to 380/100,000 in 1990. As yet, there has been no published comprehensive analysis of maternal mortality data as it pertains to Berlin and by extension Germany. Aim of the study was to evaluate and analyze the maternal mortality rate of Berlin as a result of shortcomings in healthcare provision and identify possible solutions. Methods The Institute for Quality and Transparency in the Healthcare Sector sourced external quality control from the Qualitätsbüro Berlin to provide maternal mortality data from Berlin hospitals from 2007 to 2020. Results Nineteen maternal deaths were registered between 2007 and 2020 in total. Case analysis shows that two main events occur: thrombosis and hemorrhage at 31.6%, respectively, followed by hypertensive disorder (15.8%), and sepsis (15.8%). After detailed analysis of each case report, we determined 8/19 (42.1%) maternal deaths as being potentially preventable given slightly altered circumstances. Consequences The system of registration of perinatal data in Germany does not allow for a comprehensive recording of maternal death and requires alteration to provide a more accurate picture of the phenomenon of maternal mortality; presumably, there exist twice as many unreported cases. Conclusions Symptoms, risks, and primary prevention tactics of thromboembolism during pregnancy and birth should be imparted to every licensed professional in individual hospital settings, along with evidence-based simulation training for the event of obstetric or prepartum hemorrhage.

Adverse perinatal outcomes of chlamydia infections: an ongoing challenge

Objectives Chlamydia trachomatis is one of the most common sexually transmitted diseases in the world, but there are limited data on its impact on perinatal outcomes. Our objective was to investigate the association between chlamydia infections and adverse perinatal outcomes. Methods This is a retrospective analysis of the United States Centers for Disease Control and Prevention natality live birth database for the years 2016–2019. The rates of adverse perinatal outcomes were compared between patients with a chlamydia infection during pregnancy and patients without such infection, using Pearson’s chi-square test with the Bonferroni adjustment. A multivariate logistic regression was then used to adjust outcomes for potential confounders. Results Chlamydia infections were associated with small, but statistically significant, increased odds of preterm birth (<37 weeks), early preterm birth (<32 weeks), low birthweight (<2,500 g), congenital anomalies, low 5-min Apgar score (<7), neonatal intensive care unit admission, immediate neonatal ventilation, prolonged (>6 h) neonatal ventilation, and neonatal antibiotic treatment for suspected sepsis. Conclusions Chlamydia infections during pregnancy are associated with adverse perinatal outcomes. These results call for increased education regarding the potential risks of pregnancies with a chlamydia infection, as well as for increased antenatal surveillance and post-natal pediatric assessment in these pregnancies.

Effects of oral stimulation with breast milk in preterm infants oral feeding: a randomized clinical trial

Objectives This study was performed to evaluate the effect of oral stimulation with breast milk for preterm infants. Methods A total of 68 subjects form neonatal intensive care unit were randomly assigned into control group (n=20), premature infant oral motor intervention (PIOMI) group (n=25) and premature infant oral motor intervention with breast milk (BM-PIOMI) group (n=23). Results BM-PIOMI group had significant shorter initiation of oral feeding (IOF) time compared to PIOMI group (2.95 days, 95% CI [0.42–5.48]) or control group (9.79 days, 95% CI [7.07–12.51]). BM-PIOMI group had significant sooner transition time from IOF to full oral feeding (FOF) compared to control group (6.68 days, 95% CI [2.2–11.16]), but not to PIOMI group (2.09 days, 95% CI [−2.07 to 6.25]). Length of hospital stay (LOS) did not show statistical different between three groups (control 38.85 ± 14.40 vs. PIOMI 38.48 ± 11.76 vs. BM-PIOMI 38.04 ± 12.2). Growth mixture model identified improvement in non-nutritive sucking (NNS) score in BM-PIOMI group compared to control and PIOMI group (0.8293, p<0.0001, and 0.8296, p<0.0001, respectively). Conclusions Oral stimulation with breast milk can better promotes the oral feeding process of premature infants than the simple oral stimulation, by shorten IOF time and improve early NNS score, but does not shorten transition time from IOF to FOF and LOS. Trial registration The trial identification number is ChiCTR1800019134 (Chinese Clinical Trial Registry http://www.who.int/ictrp/network/chictr2/en/)
