RESUMEN
Background: Neonatal hypothermia is a major cause of preventable morbidity and mortality, especially among the world's poorest newborns. A heat-producing wrap is necessary when kangaroo mother care (KMC) is insufficient or unavailable, yet there is little published research on such wraps. The Dream Warmer is a wrap designed to complement KMC and has been extensively studied in formal research settings but not in real-world conditions. Objectives: We used implementation science methodology to understand the safety, effectiveness, and functionality of the Dream Warmer (hereafter, "Warmer"); its effect on clinical workflows; its interaction with other aspects of care such as KMC; and the Warmer's reception by healthcare providers (HCPs) and parents. Methods: We conducted a prospective, interventional, one-arm, open-label, mixed-methods study in 6 district hospitals and 84 associated health centers in rural Rwanda. Our intervention was the provision of the Warmer and an educational curriculum on thermoregulation. We compared pre and post intervention data using medical records, audits, and surveys. Findings: The Warmer raised no safety concerns. It was used correctly in the vast majority of cases. The mean admission temperature rose from slightly hypothermic (36.41 °C) pre, to euthermic (36.53 °C) post intervention (p = 0.002). Patients achieved a temperature ≥36.5 °C in 86% of uses. In 1% of audits, patients were hyperthermic (37.6-37.9 °C). Both HCPs and parents reported a generally positive experience with the Warmer. HCPs were challenged to prepare it in advance of need. Conclusions: The Warmer functions similarly well in research and real-world conditions. Ongoing education directed toward both HCPs and parents is critical to ensuring the provision of a continuous heat chain. Engaging families in thermoregulation could ease the burden of overtaxed HCPs and improve the skill set of parents. Hypothermia is a preventable condition that must be addressed to optimize neonatal survival and outcome.

BACKGROUND: Inequity in neonatology may be potentiated within neonatal intensive care units (NICUs) by the effects of bias. Addressing bias can lead to improved, more equitable care. Understanding perceptions of bias can inform targeted interventions to reduce the impact of bias. We conducted a mixed methods study to characterize the perceptions of bias among NICU staff. METHODS: Surveys were distributed to all staff (N = 245) in a single academic Level IV NICU. Respondents rated the impact of bias on their own and others' behaviors on 5-point Likert scales and answered one open-ended question. Kruskal-Wallis test (KWT) and Levene's test were used for quantitative analysis and thematic analysis was used for qualitative analysis. RESULTS: We received 178 responses. More respondents agreed that bias had a greater impact on others' vs. their own behaviors (KWT p < 0.05). Respondents agreed that behaviors were influenced more by implicit than explicit biases (KWT p < 0.05). Qualitative analysis resulted in nine unique themes. CONCLUSIONS: Staff perceive a high impact of bias across different domains with increased perceived impact of implicit vs. explicit bias. Staff perceive a greater impact of others' biases vs. their own. Mixed methods studies can help identify unique, unit-responsive approaches to reduce bias. IMPACT: Healthcare staff have awareness of bias and its impact on their behaviors with patients, families, and staff. Healthcare staff believe that implicit bias impacts their behaviors more than explicit bias, and that they have less bias than others. Healthcare staff have ideas for strategies and approaches to mitigate the impact of bias. Mixed method studies are effective ways of understanding environment-specific perceptions of bias, and contextual assets and barriers when creating interventions to reduce bias and improve equity. Generating interventions to reduce the impact of bias in healthcare requires a context-specific understanding of perceptions of bias among staff.

We previously showed that infants born with long-gap esophageal atresia (LGEA) demonstrate clinically significant brain MRI findings following repair with the Foker process. The current pilot study sought to identify any pre-existing (PRE-Foker process) signs of brain injury and to characterize brain and corpus callosum (CC) growth. Preterm and full-term infants (n = 3/group) underwent non-sedated brain MRI twice: before (PRE-Foker scan) and after (POST-Foker scan) completion of perioperative care. A neuroradiologist reported on qualitative brain findings. The research team quantified intracranial space, brain, cerebrospinal fluid (CSF), and CC volumes. We report novel qualitative brain findings in preterm and full-term infants born with LGEA before undergoing Foker process. Patients had a unique hospital course, as assessed by secondary clinical end-point measures. Despite increased total body weight and absolute intracranial and brain volumes (cm3) between scans, normalized brain volume was decreased in 5/6 patients, implying delayed brain growth. This was accompanied by both an absolute and relative CSF volume increase. In addition to qualitative findings of CC abnormalities in 3/6 infants, normative CC size (% brain volume) was consistently smaller in all infants, suggesting delayed or abnormal CC maturation. A future larger study group is warranted to determine the impact on the neurodevelopmental outcomes of infants born with LGEA.
RESUMEN
Thrombosis and biofouling of extracorporeal circuits and indwelling medical devices cause significant morbidity and mortality worldwide. We apply a bioinspired, omniphobic coating to tubing and catheters and show that it completely repels blood and suppresses biofilm formation. The coating is a covalently tethered, flexible molecular layer of perfluorocarbon, which holds a thin liquid film of medical-grade perfluorocarbon on the surface. This coating prevents fibrin attachment, reduces platelet adhesion and activation, suppresses biofilm formation and is stable under blood flow in vitro. Surface-coated medical-grade tubing and catheters, assembled into arteriovenous shunts and implanted in pigs, remain patent for at least 8 h without anticoagulation. This surface-coating technology could reduce the use of anticoagulants in patients and help to prevent thrombotic occlusion and biofouling of medical devices.

Mutations in SCN2A gene cause a variety of epilepsy syndromes. We report a novel SCN2A-associated epilepsy phenotype in monozygotic twins with tonic seizures soon after birth and a suppression-burst electroencephalography (EEG) pattern. We reviewed the medical records, EEG tracings, magnetic resonance imaging (MRI), and neuropathologic findings, and performed whole genome sequencing (WGS) on Twin B's DNA and Sanger sequencing (SS) on candidate gene mutations. Extensive neurometabolic evaluation and early neuroimaging studies were normal. Twin A died of an iatrogenic cause at 2 weeks of life. His neuropathologic examination was remarkable for dentate-olivary dysplasia and granule cell dispersion of the dentate gyrus. Twin B became seizure free at 8 months and was off antiepileptic drugs by 2 years. His brain MRI, normal at 2 months, revealed evolving brainstem and basal ganglia abnormalities at 8 and 15 months that resolved by 20 months. At 2.5 years, Twin B demonstrated significant developmental delay. Twin B's WGS revealed a heterozygous variant c.788C>T predicted to cause p.Ala263Val change in SCN2A and confirmed to be de novo in both twins by SS. In conclusion, we have identified a de novo SCN2A mutation as the etiology for Ohtahara syndrome in monozygotic twins associated with a unique dentate-olivary dysplasia in the deceased twin.

2-methoxyestradiol (2ME2) is a potent antiangiogenic molecule that inhibits the expression of hypoxia-inducible factor (HIF)-1alpha and, consequently, of VEGF and other HIF-1alpha target genes. Although 2ME2 is elevated during pregnancy in maternal serum, its presence in fetal fluids and its impact in neonatal health are unknown. In this study, we 1) described normal levels of 2ME2 in maternal blood, cord blood, breast milk, and amniotic fluid, and 2) compared a composite measure of perinatal outcome between infants born with high and low levels of 2ME2. We found that 2ME2 was significantly decreased in all fluids compared with prepartum maternal serum. After stratifying babies by 2ME2 exposure levels, we observed no differences in the vulnerability to impaired lung development or to complications involving aberrant angiogenesis or vascular leak, such as necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), posthemorrhagic hydrocephalus (PHH), and retinopathy of prematurity (ROP). In summary, fetal 2ME2 concentrations do not appear to affect neonatal outcome.

OBJECTIVE: To test the hypothesis that exposure to preeclampsia is associated with an increased risk of bronchopulmonary dysplasia (BPD). STUDY DESIGN: A prospective cohort study of 107 babies born between 23 and 32 weeks gestation, collecting maternal, neonatal, and placental data. RESULTS: Of the 107 infants studied, 27 (25%) developed BPD. The bivariate odds ratio (OR) for the relationship between pre-eclampsia and BPD was 2.96 (95% confidence interval [CI] = 1.17 to 7.51; P = .01). When controlling for gestational age, birth weight z-score, chorioamnionitis, and other clinical confounders, the OR of developing BPD was 18.7 (95% CI = 2.44 to 144.76). Including the occurrence of preeclampsia, clinical chorioamnionitis, male sex, and maternal tobacco use in addition to gestational age and birth weight z-score accounted for 54% of the variability of the odds of developing BPD. CONCLUSIONS: BPD is increased for infants exposed to preeclampsia. This has possible implications for the prevention of BPD with proangiogenic agents, such as vascular endothelial growth factor.

AIMS: To compare belief in own effort to stay healthy, health behaviour and body mass index (BMI) among non-Western immigrants with Danish citizenship and citizens with Danish background. METHODS: Based on the National Health Interview Survey 2005, logistic regression analyses were used to examine differences in belief in own effort to stay healthy, in health behaviour and in BMI between 136 non-Western immigrants with Danish citizenship and 9,901 citizens with Danish background in the age group 25-64 years. RESULTS: Non-Western immigrants had lower odds for reporting that own effort is very important to maintain good health (odds ratio (OR) 0.45; 95% confidence interval (CI) 0.32-0.62) and for reporting consuming more alcohol on a weekly basis than recommended by the Danish National Board of Health (OR 0.21, 95% CI 0.09-0.51). The odds were higher for non-Western immigrants for than citizens with Danish background for reporting sedentary spare-time activities (OR 2.96, 95% CI 1.96-4.17), daily consumption of boiled vegetables (OR 2.50, 95% CI 1.77-3.53), and daily consumption of salad/raw vegetables (OR 2.84, 95% CI 2.02-3.99). We found no differences in daily smoking, daily fruit consumption, BMI> or =25 or BMI> or =30. CONCLUSIONS: The non-Western immigrants are healthier in terms of alcohol and vegetable consumption and unhealthier with regard to leisure-time physical activity. The non-Western immigrants are less likely to report that their own effort is important in maintaining good health.

Neonatal thromboembolism is rare and in most cases iatrogenic from indwelling central catheters, peripheral arterial lines, and umbilical lines. It often requires urgent intervention to restore perfusion and to avoid morbidity and even mortality. Very few case reports of neonatal arterial thrombosis at birth are described in the literature. We present the case of a full-term infant noted to have marked left arm swelling at birth. Doppler ultrasound of the arm demonstrated a large thrombus in the left subclavian, axillary, and brachial arteries. He underwent left arm fasciotomy and anticoagulant therapy with good recovery. We present this case with a brief review of the literature.

BACKGROUND: The length of stay in asylum centres is generally mentioned as a possible health risk to asylum seekers. Medical staff working with asylum seekers has claimed that long lengths of stay in asylum centres might cause or aggravate mental disorders. We used records from a large, multiethnic group of asylum seekers to study if the incidence of mental disorders increased with length of stay. METHODS: The study population was asylum seekers in Danish asylum centres run by the Danish Red Cross. General medical care was provided by Red Cross staff who could refer selected cases to medical specialists. If an asylum seeker needed more than three specialist consultations for mental illness or five consultations for physical illness the referrals had to be approved by The Danish Immigration Service. Between July 2001 - December 2002 the Red Cross prospectively registered health related data on all new applications (n = 4516) to the Immigration Service regarding referrals to medical specialists. We used these records to analyse the association between length of stay in the asylum centres and overall rate of referral for mental disorders. Data was analysed using weighted linear regression. RESULTS: We found that referrals for mental disorders increased with length of stay in asylum centres in a large, multiethnic population of asylum seekers. The association was found in all the categories of psychiatric illness studied and for a majority of the nationality groups studied. CONCLUSION: Length of stay in asylum centres was associated with an increase in referrals for mental disorders in a large, multiethnic group of asylum seekers. The present study supports the view that prolonged length of stay in an asylum centre is a risk factor for mental health. The risk of psychiatric illness among asylum seekers should be addressed by political and humanitarian means, giving prevention of illness the highest priority.

The detection and diagnosis of structural anomalies of the fetal central nervous system has become commonplace. Therefore, the pediatric neurosurgeon who will eventually care for a child postnatally can be called upon to interpret the meaning of diagnostic studies and advise the prospective parents prenatally. This article discusses some principals of prenatal counseling as they relate to neurosurgical conditions, reviews the diagnostic armamentarium for defining neurosurgical fetal conditions, and describes the common antenatal diagnoses that may be encountered by the neurosurgeon.
