Teaching antenatal counseling skills to neonatal providers

Counseling a family confronted with the birth of a periviable neonate is one of the most difficult tasks that a neonatologist must perform. The neonatologists goal is to facilitate an informed, collaborative decision about whether life-sustaining therapies are in the best interest of this baby. Neonatologists are trained to provide families with a detailed account of the morbidity and mortality data they believe are necessary to facilitate a truly informed decision. Yet these complicated and intensely emotional conversations require advanced communication and counseling skills that our current fellowship-training strategies are not adequately providing. We review educational models for training neonatology fellows to provide antenatal counseling at the threshold of viability. We believe that training aimed at teaching these skills should be incorporated into the neonatal-perinatal medicine fellowship. The optimal approaches for teaching these skills remain uncertain, and there is a need for continued innovation and outcomes-based research.

Preterm infants of lower gestational age at birth have greater waist circumference-length ratio and ponderal index at term age than preterm infants of higher gestational ages.

OBJECTIVE To assess anthropometric changes from birth to hospital discharge in infants born preterm and compare with a reference birth cohort of infants born full-term. STUDY DESIGN Retrospective chart review was conducted of 501 preterm and 1423 full-term infants. We evaluated birth and hospital discharge weight, length, and waist circumference (WC). WC/length ratio (WLR), ponderal index, and body mass index (BMI) were calculated. Preterm infants were categorized into quartiles (Q1-4) based on birth weight (BW). RESULTS At birth mean length, WC, WLR, BMI, and ponderal index were all significantly less for preterm infants in the lowest BW quartile (Q1) than preterm infants in higher BW quartiles or full-term infants. Although their weight, length, and BMI remained significantly less at discharge, preterm infants in Q1 had a disproportionate increase in WLR and ponderal index such that at discharge their WLR and ponderal index were greater than infants in Q2-3 and comparable with infants in Q4 and full-term infants. Discharge WLR and ponderal index in Q1 were significantly higher with decreasing postmenstrual age at birth. CONCLUSIONS Preterm infants of a lower birth postmenstrual age have disproportionate increases in WLR and ponderal index that are suggestive of increased visceral and total adiposity.

Intimate partner violence increases adverse outcomes at birth and in early infancy.

OBJECTIVE To determine the effect of intimate partner violence (IPV) on birth outcomes and infant hospitalization. STUDY DESIGN Hospitalization records for the first 4 months of life for infants born in the Military Health System in 2006-2007 were linked to Family Advocacy Program-substantiated cases of IPV among military parents. Adverse outcomes were identified using International Classification of Diseases, Ninth Revision codes. Logistic regression modeling calculated the OR of children exposed to IPV experiencing adverse outcomes. RESULTS A total of 204,546 infants were born during the study period. Among these, 173,026 infants (85%) were linked to active duty military parents. 31,603 infants (18%) experienced adverse outcomes, and 3059 infants (1.8%) were born into families with IPV. The infants exposed to IPV had a 31% increased odds of experiencing adverse outcomes compared with infants without known IPV exposure. IPV exposure increased the odds of the following outcomes: prematurity (OR, 1.45; 95% CI, 1.29-1.62), low birth weight (OR, 1.57; 95% CI, 1.25-1.97), respiratory problems (OR, 1.17; 95% CI, 1.04-1.32), neonatal hospitalization (OR, 1.39; 95% CI, 1.20-1.61), and postneonatal hospitalization (OR, 1.52; 95% CI, 1.29-1.81). After controlling for prematurity and demographic variables, IPV exposure was associated with low birth weight (OR, 1.52; 95% CI, 1.16-1.99), neonatal hospitalization (OR, 1.24; 95% CI, 1.02-1.49), and postneonatal hospitalization (OR, 1.27; 95% CI, 1.03-1.56). CONCLUSION Infants exposed to IPV are more likely to experience adverse birth outcomes and infant hospitalization. Routinely addressing IPV during prenatal and early pediatric visits may potentially prevent these adverse outcomes.

Is Treatment Futile for an Extremely Premature Infant With Giant Omphalocele

Doctors have no ethical obligation to provide futile treatment. This has been true since the time of Hippocrates who warned physicians not to treat patients who were “overmastered by their disease.” This principle remains valid today but, as the Society for Critical Care Medicine notes, it is difficult to identify treatment as absolutely futile in all but a few clinical situations. Far more common, they note, are “treatments that are extremely unlikely to be beneficial, are extremely costly, or are of uncertain benefit.” These, they say, “may be considered inappropriate and hence inadvisable, but should not be labeled futile.” So what should doctors do when they have a case that seems close to the futility threshold but does not, perhaps, quite cross it? In such cases, is it appropriate to make unilateral decisions to withhold life-sustaining treatment even if the family objects? Or should treatment be provided knowing that it might cause pain and suffering to an infant with no likelihood of benefit? To address these questions, we present a case of an extremely premature infant with a giant omphalocele and ask 3 neonatologists, Dr Dalia Feltman of Evanston Hospital, Dr Theophil Stokes of the Walter Reed Medical Center, and Dr Jennifer Kett, a neonatologist and fellow in bioethics at Seattle Children’s Hospital, to comment.

Novel noninvasive anthropometric measure in preterm and full-term infants: normative values for waist circumference:length ratio at birth.

Background:Waist circumference:length ratio (WLR) and ponderal index (PI) appear to be useful markers of visceral and total adiposity, respectively. However, there are no normative birth data across the full range of gestational ages.Methods:In this retrospective cohort study of 500 preterm and 1,426 full-term infants, born in 1998 and 2008 at three military hospitals, the percentile growth curves for WLR and PI were calculated. There were no sex differences, and results were combined to obtain values from 26 to 42 wk gestation.Results:Between 26 and 42 wk gestation, median birth WLR increased from 0.55 to 0.62, and median PI increased from 21.1 to 25.6. The adjusted mean WLR at birth among infants born <34 wk increased from 0.55 in 1998 to 0.58 in 2008 (P = 0.048), suggesting that early-preterm infants born in 2008 had greater abdominal adiposity than those born in 1998.Conclusion:We report normative birth data for WLR and PI in preterm and full-term infants by gestational age and sex. WLR and PI may be useful as clinical markers of visceral and overall adiposity. In conjunction with other anthropometric measures, WLR and PI may be useful to monitor postnatal nutrition and growth and assess risk for later obesity and cardiometabolic disorders.

Prenatal, perinatal, and neonatal risk factors of autism spectrum disorder

BackgroundWe explored the association of 29 previously reported neonatal, perinatal, and prenatal conditions, and exposures with later diagnosis of autism spectrum disorder (ASD) in a large sample of children followed over multiple years.MethodsA retrospective case–cohort study was formed using the Military Health System database. Cases were identified by International Classification of Diseases, Ninth Revision codes for ASD between 2000 and 2013, and were matched 3:1 with controls on sex, date of birth, and enrollment time frame. Exposures included 29 conditions previously associated with ASD; 17 prenatal conditions and their pharmaceutical treatment, 5 perinatal conditions, and 6 neonatal conditions.ResultsA total of 8,760 children diagnosed with ASD between the ages of 2 and 18 years were matched with 26,280 controls. ASD is associated with maternal mental illness, epilepsy, obesity, hypertension, diabetes, polycystic ovary syndrome, infection, asthma, assisted fertility, hyperemesis, younger maternal age, labor complications, low birth weight, infant infection, epilepsy, birth asphyxia, and newborn complications. The greatest increased risk was associated with infant epilepsy (odds ratio (OR) 7.57 (5.68–10.07)), maternal mental health (OR 1.80 (1.65–1.96)), and epilepsy (OR 1.60 (1.02–2.50)) medications.ConclusionASD is associated with a range of prenatal, perinatal, and neonatal factors, with the highest magnitude associations with maternal medication use and neonatal seizure.
