Placental Chorioangioma with Nonimmune Hydrops Fetalis.

A 38-year-old woman was found to have a large placental chorioangioma. The fetus was studied using ultrasound. The pregnancy became complicated by hydrops fetalis, polyhydramnios, and abruptio placenta. The infant delivered at 29 weeks' gestational age. The neonatal course was complicated by nonimmune hydrops fetalis, respiratory distress syndrome, anemia, pulmonary hemorrhage, intraventricular hemorrhage, necrotizing enterocolitis, and bronchopulmonary dysplasia. The infant was discharged home with breastfeeding and off oxygen at 50 days of life. This case represents the multidisciplinary approach to the pregnancy complicated by a large placental chorioangioma and the resulting premature neonate with nonimmune hydrops fetalis.

Examination of cord blood at birth in women with SARS-CoV-2 exposure and/or vaccination during pregnancy and relationship to fetal complete blood count, cortisol, ferritin, vitamin D, and CRP.

Background: SARS-CoV-2 is known to manifest a robust innate immune response. However, little is known about inflammatory influences from maternal SARS-CoV-2 infection or maternal mRNA vaccination upon the fetus. In addition, it is unknown if Vitamin D deficiency influences fetal homeostasis or if an anti-inflammatory mechanism to the development of possible innate cytokines or acute phase reactants by the maternal/fetal dyad, in the form of cortisol elevations, occur. In addition, effects on Complete Blood Count (CBC) are not known. Objective: To evaluate the neonatal acute phase reactants and anti-inflammatory responses after maternal SARS-CoV-2 disease or mRNA vaccination. Methods: Samples and medical records reviews from mother/baby dyads (n = 97) were collected consecutively, and were categorized into 4 groups; no SARS-CoV-2 or vaccination exposure (Control), Vaccinated mothers, maternal SARS-CoV-2 disease positive/IgG titer positive fetal blood, and maternal SARS-CoV-2 positive/IgG titer negative fetal blood. SARS-CoV-2 IgG/IgM/IgA titers, CBC, CRP, ferritin, cortisol, and Vitamin D were obtained to examine the possible development of an innate immune response and possible anti-inflammatory response. Student's t-test, Wilcoxon rank-sum, and Chi-squared with Bonferroni corrections were used to compare groups. Multiple imputations were performed for missing data. Results: Cortisol was higher in babies of both mothers who were vaccinated (p = 0.001) and SARS-CoV-2 positive/IgG positive (p = 0.009) as compared to the control group suggesting an attempt to maintain homeostasis in these groups. Measurements of ferritin, CRP, and vitamin D did not reach statistical significance. CBC showed no variation, except for the mean platelet volume (MPV), which was elevated in babies whose mothers were vaccinated (p = 0.003) and SARS-CoV-2 positive/IgG positive (p = 0.007) as compared to the control group. Conclusion: Acute phase reactant elevations were not noted in our neonates. Vitamin D levels were unchanged from homeostatic levels. Cord blood at birth, showed Cortisol and MPV higher in vaccinated and SARS-CoV-2 IgG positive mother/baby dyads as compared to the Control group, indicating that possible anti-inflammatory response was generated. The implication of possible inflammatory events and subsequent cortisol and/or MPV elevation effects upon the fetus after SARS-CoV-2 disease or vaccination is unknown and merits further investigation.

Early enteral feeding in very low birth weight infants.

BACKGROUND/AIM: Debate exists about when to initiate enteral feeding (EF) in very low birth weight (VLBW) preterm infants. This retrospective study compared the effectiveness of an education-based quality improvement project and the relationship of time of the first EF to necrotizing enterocolitis (NEC) or death incidence and parenteral nutrition (PN) days in VLBW infants. STUDY DESIGN/SUBJECTS: VLBW infants born in 2 epochs were compared for hour of the first feed, PN days, NEC or death incidence, and feeding type. The 2 epochs were temporally divided by a quality improvement initiative to standardize initiation of EF in postnatal hours 6-24. RESULTS: 603 VLBW infants were included. Median time of feed initiation decreased from 33 (Epoch 1) to 14h (Epoch 2) (p<0.0001). Median PN days were 14 vs. 12, respectively (p=0.07). The incidence of NEC or death was 13.4% vs. 9.5%, respectively (p=0.14). When controlling for birth weight, gestational age, race, gender, and time period, earlier feed initiation was associated with decreased NEC or death (p=0.003). Evaluation of the relationship of early EF (defined as within the first 24h) in Epoch 2 alone showed that early EF was significantly associated with decreased NEC or death (6.3 vs 15.1%) (RR, 95% CI=0.28, 0.13-0.58) and less PN days (p<0.0001). CONCLUSIONS: In a VLBW infant cohort, an education-based process improvement initiative decreased time of EF initiation to a median of 14h with no associated increase in NEC or death. In fact, results suggest that earlier feeding is associated with decreased NEC or death.
