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.

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.

Longitudinal growth changes from birth to 8-9 years in preterm and full term births.

BACKGROUND: The aim of this study is to assess the effect of age at adiposity rebound (AR) and changes in growth between birth and 6 months on growth status at 8-9 years in children born term and preterm. Age at AR is inversely correlated with risk for later obesity in children born full term, but has not been analyzed in children born preterm. METHODS: Birth anthropometrics, and weight and length/height data from age 6 months through 8-9 years were recorded for 175 children born in 2008 in the military health system. Calculated variables include body mass index (BMI, kg/m2), Z-scores, and age at AR. RESULTS: Age at AR could be calculated for 150 children (32% preterm); average age was 5.4 years and 5.3 years for children born term and preterm, respectively (NS). For children born term and preterm, there was a significant correlation between younger age at AR and higher BMI Z-score at 8-9 years (r = - 0.685), and a direct relationship between weight Z-score change from birth to 6 months and weight Z-scores at 8-9 years (p = 0.034). CONCLUSIONS: Younger age at AR correlates with higher BMI Z-score at 8-9 years in children born both term and preterm. Weight gain from birth to 6 months correlates with weight Z-score at 8-9 years. These results emphasize the importance of younger age at AR in addition to greater early weight gain as an indicator of later obesity.

Caring for Families at the Limits of Viability: The Education of Dr Green.

Resuscitation decisions for infants born at the edges of viability are complicated moral dilemmas, and the process of making these decisions is emotionally exhausting and morally distressful for families and physicians alike. An ethical approach to making these decisions requires input from physicians and parents; individuals tasked with facilitating such decisions must possess the communication and counseling skills needed to assist families with these painful and life-altering decisions. It is incumbent on all of us to continue our investigation into how we can better assist families in this process while providing care that is in their best interest.

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 neonatologist's 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.

Myocardial infarction in a newborn heterozygous for the MTHFR C677T mutation.

Neonatal myocardial infarction secondary to congenital heart disease, anomalous coronary artery anatomy, thromboembolism, coagulopathy, birth asphyxia, and unknown causes has been previously reported. We now report an infant who suffered a massive myocardial infarction during birth, requiring extensive resuscitation and aggressive management. A thrombus, the origin of which was not detected on autopsy, was found occluding the proximal left coronary artery several hours after birth. Genetic studies revealed a single copy variant of the MTHFR C677T mutation that we speculate may have predisposed the infant to coronary thrombosis.
