In the last decades the reported incidence of preterm necrotizing enterocolitis (NEC) has been declining in large part due to implementing comprehensive NEC prevention initiatives, including breast milk feeding, standardized feeding protocols, transfusion guidelines, and antibiotic stewardship and improving the rigor with which non-NEC cases are excluded from NEC data. However, after more than 60 years of NEC research in animal models, the promise of a "magic bullet" to prevent NEC has yet to materialize. There are also serious issues involving clinical NEC research...

OBJECTIVE: While delayed umbilical cord clamping (UCC) is thought to facilitate placental to infant blood transfusion, the physiological factors regulating flow in the umbilical arteries and veins during delayed UCC is unknown. We investigated the effects of gravity, by changing fetal height relative to the placenta, and ventilation on umbilical blood flows and the cardiovascular transition during delayed UCC at birth. METHODS: Catheters and flow probes were implanted into preterm lambs (128 days) prior to delivery to measure pulmonary, carotid, umbilical artery (UaBF) and umbilical venous (UvBF) blood flows...

This systematic review evaluates the effectiveness of delayed cord clamping in preterm infants on reducing postdelivery complications of anemia, hemodynamic instability, and the development of intraventricular hemorrhages. Interventions included varying durations of delayed cord clamping with and without cord milking as compared with immediate cord clamping, shorter delays in cord clamping, and delayed cord clamping without cord milking. A comprehensive search of randomized controlled trials, observational, cohort, and before-after studies was conducted between 1946 and 2015 in the electronic databases of Ovid MEDLINE, Embase, and Google Scholar...

OBJECTIVE: To determine whether adverse outcomes were more common in late preterm pregnancies complicated by preeclampsia and growth restriction compared to those affected by preeclampsia alone. METHODS: This was a retrospective cohort study of 8,927 singleton pregnancies with preeclampsia. Pregnancies with small for gestational age (SGA) neonates (birthweight <10(th) percentile) were compared to those appropriate for gestational age (AGA) neonates. Maternal outcomes included cesarean delivery (CD) rate, CD for fetal heart rate (FHR) abnormalities, abruption, postpartum hemorrhage (PPH), maternal transfusion, acute renal failure, and peripartum cardiomyopathy...

AIM: Jaundice may cause auditory toxicity (auditory neuropathy and hearing loss). However, total serum bilirubin (TSB) does not discriminate neonates at risk for auditory toxicity. We compared TSB, bilirubin:albumin molar ratio (BAMR), and unbound bilirubin for their association with auditory toxicity in neonates with severe jaundice (TSB ≥342μmol/L, or that met exchange transfusion). METHOD: Neonates greater or equal to 34 weeks gestational age with severe jaundice during the first 2 postnatal weeks were eligible for prospective cohort study, unless they had craniofacial malformations, chromosomal disorders, toxoplasmosis, other infections, rubella, cytomegalovirus, herpes simplex infections, surgery, or family history of congenital deafness...

REVIEW
Clare L Whitehead, Susan P Walker, Stephen Tong
Circulating nucleic acids have revolutionized prenatal diagnosis in the last decade, allowing non-invasive screening for single gene or chromosomal defects using a single sample of maternal blood. In addition to DNAs, RNAs from the placenta are released into the maternal blood from early in pregnancy and may reflect changes in gene expression occurring within the placenta. Measuring circulating RNA may therefore provide insights into the placental transcriptome without the need for invasive testing. Combined with advances in next-generation sequencing and molecular analyses, it may be possible to measure circulating RNA to improve our understanding of placental pathology and develop novel non-invasive biomarkers for pregnancy complications and monitoring high-risk pregnancies...

OBJECTIVES: Amniopatch is a proposed treatment of iatrogenic preterm premature rupture of membranes (iPPROM). We studied characteristics associated with successful amniopatch treatment of iPPROM after fetoscopic laser surgery for twin-twin transfusion syndrome. METHODS: Patients with iPPROM within 15 days of laser surgery treated with an amniopatch were studied. Factors associated with amniopatch success (i.e. cessation of leakage with normalization of amniotic fluid volume) were tested univariately and in multivariate logistic regression models...

CONTEXT: -Transfusion-associated graft-versus-host disease is a rare, often fatal complication of cellular blood product transfusion. The requirement that at-risk groups receive irradiated products reduces the incidence of transfusion-associated graft-versus-host disease. A comprehensive survey of irradiation practices has not been performed since 1989; meanwhile, new indications for irradiation have emerged. OBJECTIVE: -To assess current irradiation practices at College of American Pathologists member institutions...

Anemia of prematurity remains a common complication despite recent advances in perinatal and neonatal medicine. The delayed cord clamping (at least 30seconds as recommended) has several benefits: increased hemoglobin and hematocrit levels at birth, improved initial hemodynamic, decreased incidence of transfusions and intraventricular hemorrhages. When the birth transition is difficult, wait 30seconds before clamping can be impossible. So as not to interfere with the neonatal resuscitation, the "milking" has been proposed as an alternative method to the delayed cord clamping...

BACKGROUND: The mechanisms involved in bleeding in cases of placenta previa (PP) and the effect on pregnancy outcome is unclear. OBJECTIVES: We aimed to compare pregnancy outcome and placental histopathology in pregnancies complicated with symptomatic (bleeding) vs. non-symptomatic PP, and to study the effects of the co-existence of histopathological retro-placental hemorrhage (RPH) in cases of symptomatic PP on neonatal and maternal outcomes. STUDY DESIGN: Labor and maternal characteristics, neonatal outcome and placental histopathology lesions of pregnancies with PP, delivered between 24 and 42weeks, during 2009-2015, were reviewed...

Immune thrombocytopenic purpura is a common acquired autoimmune disorder defined by a low platelet count secondary to accelerated platelet destruction or impaired thrombopoesis by anti-platelet antibodies. Thrombopoietin (TPO)-mimetic drugs such as eltrombopag and romiplostim have been used successfully in many nonpregnant individuals with immune thrombocytopenia (ITP) but studies based on its effects in pregnancy are limited. A 27-year-old multigravida who is a known case of ITP with bad obstetric history was referred to the Department of Obstetrics and Gynecology at 26 weeks of gestation with complaints of mucosal bleeding and recurrent abortions...

Based on small studies and not on statistically valid clinical trials, guidelines for neonatal transfusions remain controversial and practices vary greatly. Premature infants and critically ill neonates in the neonatal intensive care unit (NICU) often require blood transfusions and extremely preterm neonates receive at least one red blood cell transfusion during their hospital stay. Transfusions to neonates convey both benefits and risks and consequently it is imperative to establish specific guidelines to improve practice and avoid unnecessary transfusions...
