Should Neonatologists Give Opinions Withdrawing Life-Sustaining Treatment?, J S. Blumenthal-Barby, Laura Loftis, Christy L. Cummings, William Meadow, Monica Lemmon, Peter A. Ubel, Laurence Mccullough, Emily Rao, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

An infant has a massive intracranial hemorrhage. She is neurologically devastated and ventilator-dependent. The prognosis for pulmonary or neurologic recovery is bleak. The physicians and parents face a choice: withdraw the ventilator and allow her to die or perform a tracheotomy? The parents cling to hope for recovery. The physician must decide how blunt to be in communicating his own opinions and recommendations. Should the physician try to give just the facts? Or should he also make a recommendation based on his own values? In this article, experts in neonatology, decision-making, and bioethics discuss this situation and the choice that …

Progress Toward Eliminating Mother To Child Transmission Of Hiv In Kenya: Review Of Treatment Guideline Uptake And Pediatric Transmission At Four Government Hospitals Between 2010 And 2012., Sarah Finocchario-Kessler, Kristine F. Clark, Samoel Khamadi, Brad J. Gautney, Vincent Okoth, Kathy Goggin, Hitsystem Study Team

Manuscripts, Articles, Book Chapters and Other Papers

We analyzed prevention of mother-to-child transmission (PMTCT) data from a retrospective cohort of n = 1365 HIV+ mothers who enrolled their HIV-exposed infants in early infant diagnosis services in four Kenyan government hospitals from 2010 to 2012. Less than 15 and 20 % of mother-infant pairs were provided with regimens that met WHO Option A and B/B+ guidelines, respectively. Annually, the gestational age at treatment initiation decreased, while uptake of Option B/B+ increased (all p's < 0.001). Pediatric HIV infection was halved (8.6-4.3 %), yet varied significantly by hospital. In multivariable analyses, HIV-exposed infants who received no PMTCT (AOR 4.6 [2.49, 8.62], p < 0.001), mixed foods (AOR 5.0 [2.77, 9.02], p < 0.001), and care at one of the four hospitals (AOR 3.0 [1.51, 5.92], p = 0.002) were more likely to be HIV-infected. While the administration and uptake of WHO PMTCT guidelines is improving, an expanded focus on retention and medication adherence will further reduce pediatric HIV transmission.

Objective was to describe the relationship between the number of sterile site infections and duration of neutropenia during the first four cycles of chemotherapy and the risk of recurrence and overall survival in children with newly diagnosed acute myeloid leukemia (AML). AAML0531 was a Children's Oncology Group randomized phase 3 clinical trial that included 1022 children with de novo AML. For this analysis, we focused on non-Down syndrome favorable and standard risk patients who completed at least 4 cycles of chemotherapy without recurrence or withdrawal during protocol therapy. Those receiving hematopoietic stem cell transplantation in first remission were excluded. Five …

Risk Factors For Sleep-Related Infant Deaths In In-Home And Out-Of-Home Settings., Hilina Kassa, Rachel Y. Moon, Jeffrey D. Colvin

Manuscripts, Articles, Book Chapters and Other Papers

Background and objective: Multiple environmental risk factors are associated with sleep-related infant deaths. Little is known about differences in risk factors for deaths occurring in-home and out-of-home. We sought to compare risk factors for in-home and out-of-home infant deaths.

Methods: We conducted a cross-sectional analysis of sleep-related infant deaths from 2004 to 2014 in the National Child Fatality Review and Prevention database. The main exposure was setting (in-home versus out-of-home) at time of death. Primary outcomes were known risk factors: sleep position, sleep location (eg, crib), objects in the environment, and bed sharing. Risk factors for in-home versus out-of-home deaths …

Faculty Publications

BACKGROUND: The association between infant formula feeding at birth and subsequent feeding patterns in a low- or middle-income context is not clear. OBJECTIVE: We examined the association of infant formula feeding during the first 3 d after birth with subsequent infant formula feeding and early breastfeeding cessation in Vietnam. METHODS: In a cross-sectional survey, we interviewed 10,681 mothers with children aged 0-23 mo (mean age: 8.2 mo; 52% boys) about their feeding practices during the first 3 d after birth and on the previous day. We used stratified analysis, multiple logistic regression, propensity score-matching analysis, and structural equation modeling to …

Ontogeny Of Hepatic Drug Transporters As Quantified By Lc-Ms/Ms Proteomics., B Prasad, Andrea Gaedigk, M Vrana, R Gaedigk, J Steven Leeder, L Salphati, X Chu, G Xiao, Ceca Hop, R Evers, L Gan, J D Unadkat

Manuscripts, Articles, Book Chapters and Other Papers

Protein expression of major hepatic uptake and efflux drug transporters in human pediatric (n = 69) and adult (n = 41) livers was quantified by liquid chromatography / tandem mass spectroscopy (LC-MS/MS). Transporter protein expression of OCT1, OATP1B3, P-gp, and MRP3 was age-dependent. Particularly, significant differences were observed in transporter expression (P < 0.05) between the following age groups: neonates vs. adults (OCT1, OATP1B3, P-gp), neonates or infants vs. adolescents and/or adults (OCT1, OATP1B3, and P-gp), infants vs. children (OATP1B3 and P-gp), and adolescents vs. adults (MRP3). OCT1 showed the largest increase, of almost 5-fold, in protein expression with age. Ontogenic expression of OATP1B1 was confounded by genotype and was revealed only in livers harboring SLCO1B1*1A/*1A. In livers >1 year, tissues harboring SLCO1B1*14/*1A showed 2.5-fold higher (P < 0.05) protein expression than SLCO1B1*15/*1A. Integration of these ontogeny data in physiologically based pharmacokinetic (PBPK) models will be a crucial step in predicting hepatic drug disposition in children.

Faculty Publications

AIM: It is unknown whether maternal malnutrition reduces the effect of counselling on exclusive breastfeeding. This study evaluated the effect of breastfeeding counselling on the duration of exclusive breastfeeding, and whether the timing of prenatal food and different micronutrient supplements further prolonged this duration. METHODS: Pregnant women in Matlab, Bangladesh, were randomised to receive daily food supplements of 600 kcal at nine weeks of gestation or at the standard 20 weeks. They also were allocated to either 30 mg of iron and 400 μg folic acid, or the standard programme 60 mg of iron and folic acid or multiple micronutrients. …

Predictors Of Infant Age At Enrollment In Early Infant Diagnosis Services In Kenya., Kathy Goggin, Catherine Wexler, Niaman Nazir, Vincent S. Staggs, Brad Gautney, Vincent Okoth, Samoel A Khamadi, Andrea Ruff, Michael Sweat, An-Lin Cheng, Sarah Finocchario-Kessler

Manuscripts, Articles, Book Chapters and Other Papers

Despite the importance of early detection to signal lifesaving treatment initiation for HIV+ infants, early infant diagnosis (EID) services have received considerably less attention than other aspects of prevention of mother to child transmission care. This study draws on baseline data from an on-going cluster randomized study of an intervention to improve EID services at six government hospitals across Kenya. Two logistic regressions examined potential predictors of "on time" (infant ≤6 weeks of age) vs. "late" (≥7 weeks) and "on time" versus "very late" (≥12 weeks) EID engagement among 756 mother-infant pairs. A quarter of the infants failed to get …

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVES: Risk factors for failure to thrive (FTT) readmissions, including medical complexity, have not been described. We sought to characterize children hospitalized for FTT and identify risk factors associated with FTT-specific readmissions during the current era of increasing medical complexity among hospitalized children.

METHODS: This retrospective cohort study used the Pediatric Health Information System database of 43 freestanding children's hospitals across the United States. The cohort included childrenmodels, we assessed the association of demographic, clinical, diagnostic, and treatment characteristics with FTT-specific readmission.

RESULTS: There were 10 499 FTT hospitalizations, with 14.1% being readmitted for FTT within 3 years and 4.8% …

Two Cases Of Transcatheter Closure Of Central Aortopulmonary Shunts: One With An Amplatzer Duct Occluder Ii And One With An Amplatzer Vascular Plug I, Ahmet Celebi, Ilker Kemal Yucel, Sevket Balli, Mehmet Kucuk

The Texas Heart Institute Journal

When total correction is not possible in infants who have a cyanotic congenital heart disease, creation of a palliative aortopulmonary shunt is essential. A central aortopulmonary shunt is preferable, because of its technical and hemodynamic advantages. Overcirculation, thrombosis, and stenosis of the shunt are the main postoperative sequelae that necessitate urgent reintervention. Percutaneous transcatheter closure of aortopulmonary shunts can eliminate the need for reoperation and substantially decrease postoperative morbidity and mortality rates. We report our successful transcatheter closures of central aortopulmonary shunts in a 3-month-old infant and a 15-year-old girl, with use of an Amplatzer Duct Occluder II and an …

Manuscripts, Articles, Book Chapters and Other Papers

Although there have been many developments related to specific strategies for treating patients after poisoning exposures, the mainstay of therapy remains symptomatic and supportive care. One of the most aggressive supportive modalities is extracorporeal membrane oxygenation (ECMO). Our goal was to describe the use of ECMO for toxicological exposures reported to the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC). We performed a retrospective review of the ACMT ToxIC Registry from January 1, 2010 to December 31, 2013. Inclusion criteria included patients aged 0 to 89 years, evaluated between January 2010 through December 2013, and received ECMO for …

Professionalism requires that doctors acknowledge their errors and figure out how to avoid making similar ones in the future. Over the last few decades, doctors have gotten better at acknowledging mistakes and apologizing to patients when a mistake happens. Such disclosure is especially complicated when one becomes aware of an error made by a colleague. We present a case in which consultant surgeons became aware that a colleague seemed to have made a serious error. Experts in surgery and bioethics comment on appropriate responses to this situation.

Molecular Evolution And Intraclade Recombination Of Enterovirus D68 During The 2014 Outbreak In The United States., Yi Tan, Ferdaus Hassan, Jennifer E. Schuster, Ari Simenauer, Rangaraj Selvarangan, Rebecca A. Halpin, Xudong Lin, Nadia Fedorova, Timothy B. Stockwell, Tommy Tsan-Yuk Lam, James D. Chappell, Tina V. Hartert, Edward C. Holmes, Suman R. Das

In August 2014, an outbreak of enterovirus D68 (EV-D68) occurred in North America, causing severe respiratory disease in children. Due to a lack of complete genome sequence data, there is only a limited understanding of the molecular evolution and epidemiology of EV-D68 during this outbreak, and it is uncertain whether the differing clinical manifestations of EV-D68 infection are associated with specific viral lineages. We developed a high-throughput complete genome sequencing pipeline for EV-D68 that produced a total of 59 complete genomes from respiratory samples with a 95% success rate, including 57 genomes from Kansas City, MO, collected during the 2014 …

Down-Regulation Of Placental Neuropilin-1 In Fetal Growth Restriction., Dev Maulik, Alok De, Louis Ragolia, Jodi Evans, Dmitry Grigoryev, Kamani Lankachandra, David Mundy, Jolene Muscat, Mary M. Gerkovich, Shui Qing Ye

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Fetal growth restriction (FGR) is associated with adverse outcomes extending from fetal to adult life, and thus, constitutes a major health care challenge. Fetuses with progressive growth restriction show increasing impedance in the umbilical artery flow, which may become absent during end-diastole. Absent end-diastolic flow (AEDF) is associated with adverse perinatal outcomes including stillbirths and perinatal asphyxia. Placentas from such pregnancies demonstrate deficient fetoplacental vascular branching. Current evidence, moreover, indicates an antiangiogenic state in maternal circulation in several pregnancy complications including preeclampsia, small-for-gestational-age births, fetal death, and preterm labor. The angiogenic mediators in maternal circulation are predominantly of placental …

Tough Decisions For Premature Triplets., Ashley Hurst, Scott And Emily (Parents), Brooke D. Vergales, Alix Paget-Brown, Mark Mercurio, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

When infants are born at the borderline of viability, doctors and parents have to make tough decisions about whether to institute intensive care or provide only palliative care. Often, these decisions are made in moments of profound emotional turmoil, and parents receive different information from different health professionals. Communication can become garbled. It may be difficult to tell when and whether the patient's clinical condition has changed enough so that certain choices that had once been permissible become impermissible. In this "Ethics Rounds," we present a case of triplets born at the borderline of viability. We sought comments from the …

OBJECTIVE: To assess whether late surfactant treatment in extremely low gestational age (GA) newborn infants requiring ventilation at 7-14 days, who often have surfactant deficiency and dysfunction, safely improves survival without bronchopulmonary dysplasia (BPD).

STUDY DESIGN: Extremely low GA newborn infants (GA ≤28 0/7 weeks) who required mechanical ventilation at 7-14 days were enrolled in a randomized, masked controlled trial at 25 US centers. All infants received inhaled nitric oxide and either surfactant (calfactant/Infasurf) or sham instillation every 1-3 days to a maximum of 5 doses while intubated. The primary outcome was survival at 36 weeks postmenstrual age (PMA) without …

Whole-Genome Sequencing And Disability In The Nicu: Exploring Practical And Ethical Challenges., Michael J. Deem

Manuscripts, Articles, Book Chapters and Other Papers

Clinical whole-genome sequencing (WGS) promises to deliver faster diagnoses and lead to better management of care in the NICU. However,several disability rights advocates have expressed concern that clinical use of genetic technologies may reinforce and perpetuate stigmatization of and discrimination against disabled persons in medical and social contexts. There is growing need, then, for clinicians and bioethicists to consider how the clinical use of WGS in the newborn period might exacerbate such harms to persons with disabilities. This article explores ways to extend these concerns to clinical WGS in neonatal care. By considering these perspectives during the early phases of …

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Reduce central line-associated bloodstream infection (CLABSI) rates 15% over 12 months in children's hospital NICUs. Use orchestrated testing as an approach to identify important CLABSI prevention practices.

METHODS: Literature review, expert opinion, and benchmarking were used to develop clinical practice recommendations for central line care. Four existing CLABSI prevention strategies (tubing change technique, hub care monitoring, central venous catheter access limitation, and central venous catheter removal monitoring) were identified for study. We compared the change in CLABSI rates from baseline throughout the study period in 17 participating centers. Using orchestrated testing, centers were then placed into 1 of 8 …

Introduction To Bioethics Special Supplement V: Ethical Issues In Genomic Testing Of Children., John D. Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Next-generation genome sequencing of children is one of the most promising and most challenging new technologies in pediatrics. On the one hand, it offers the hope that we will be able to diagnose rare conditions that were previously impossible to diagnose, which, in turn, might lead to new treatments. On the other hand, the technology for sequencing presents daunting problems of interpretation. It is problematic to conduct the research necessary to characterize the pathogenicity of those variants at the same time that we are using them to guide the clinical care of children who have complex medical problems. It is …
