BACKGROUND: The DiGeorge syndrome, the most common of the microdeletion syndromes, affects multiple organs, including the heart, the nervous system, and the kidney. It is caused by deletions on chromosome 22q11.2; the genetic driver of the kidney defects is unknown.

METHODS: We conducted a genomewide search for structural variants in two cohorts: 2080 patients with congenital kidney and urinary tract anomalies and 22,094 controls. We performed exome and targeted resequencing in samples obtained from 586 additional patients with congenital kidney anomalies. We also carried out functional studies using zebrafish and mice.

RESULTS: We identified heterozygous deletions of 22q11.2 in 1.1% …

Infection Control In Labor And Delivery Room, Learning From The Small Hospital Based Project, Savera Aziz Ali, Sumera Aziz Ali

School of Nursing & Midwifery

Background: It has been estimated that around 36% of the neonatal deaths occur due to infection in the lower and middle income countries. Infection control is a more substantial area of concern, particularly in Labor and delivery room. Multiple factors can cause infection in the labor room, therefore it is important to assess various factors of maternal and neonatal infection. Hence we explored multiple factors through this project and developed the action plan to address those factors effectively.
Methods: During our Leadership and Management course, we conducted a project in Labor room pertaining to a prevalent issue. The whole process …

Reexamining The Hypoglycemia Fear Survey For Parents Of Young Children In A Sample Of Children Using Insulin Pumps., Susana R. Patton, Amy E. Noser, Mark A. Clements, Lawrence M. Dolan, Scott W. Powers

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: We update the psychometric properties of the Hypoglycemia Fear Survey-Parents of Young Children (HFS-PYC), a 26-item measure of parents' hypoglycemia fear for young children using an insulin pump.

METHODS: We combined three similar datasets for the analyses. The data analyzed included parents' responses to the HFS-PYC and a demographic form. For a subset of children (n = 91), we also analyzed self-monitoring of blood glucose data. We used confirmatory factor analysis (CFA) to confirm the measure's original factor structure. Additional analyses examined reliability and validity of a revised HFS-PYC for parents of young children using pumps.

RESULTS: We analyzed …

Surrogate Pregnancy After Prenatal Diagnosis Of Spina Bifida., Lynnette J. Mazur, Mary Kay Kisthardt, Helen H. Kim, Laura M. Rosas, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Some pregnancies today involve infertile individuals or couples who contract with a fertile woman to carry a pregnancy for them. The woman who carries the pregnancy is referred to as a "gestational carrier." The use of such arrangements is increasing. Most of the time, these arrangements play out as planned; sometimes, however, problems arise. This article discusses a case in which a fetal diagnosis of spina bifida led the infertile couple to request that the gestational carrier terminate the pregnancy, and the gestational carrier did not wish to do so. Experts in the medical and legal issues surrounding surrogacy discuss …

Use Of The Ketogenic Diet In The Neonatal Intensive Care Unit-Safety And Tolerability., Lindsey M. Thompson, Erin Day Fecske, Mohammad Salim, Ara Hall

Manuscripts, Articles, Book Chapters and Other Papers

Drug-resistant epilepsy poses a challenge in neonatal patients, especially those in the neonatal intensive care unit (NICU), who have various secondary comorbidities. We present results of four children with a history of drug-resistant epilepsy for whom a ketogenic diet was initiated and used in the NICU. A nonfasting induction into ketosis over 1-2 weeks was utilized, with gradual increases in the ketogenic ratio every 2-3 days. Data were collected retrospectively from a database, which included medical history, daily progress notes, relevant laboratory data, and imaging and diagnostic information. The ketogenic diet was well tolerated in all cases. The most common …

High Throughput In Vivo Functional Validation Of Candidate Congenital Heart Disease Genes In Drosophila., Jun-Yi Zhu, Yulong Fu, Margaret Nettleton, Adam Richman, Zhe Han

Pediatrics Faculty Publications

Genomic sequencing has implicated large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system is needed to validate gene associations with pathology. We developed a Drosophila-based functional system to screen candidate disease genes identified from Congenital Heart Disease (CHD) patients. 134 genes were tested in the Drosophila heart using RNAi-based gene silencing. Quantitative analyses of multiple cardiac phenotypes demonstrated essential structural, functional, and developmental roles for more than 70 genes, including a subgroup encoding histone H3K4 modifying proteins. We also demonstrated the use of Drosophila to evaluate cardiac phenotypes resulting …

Abnormal Glycosylation In Joubert Syndrome Type 10., Megan S Kane, Mariska Davids, Michelle R Bond, Christopher J Adams, Megan E Grout, Ian G Phelps, Gilbert Vezina, +Several Additional Authors

Neurology Faculty Publications

BACKGROUND: The discovery of disease pathogenesis requires systematic agnostic screening of multiple homeostatic processes that may become deregulated. We illustrate this principle in the evaluation and diagnosis of a 5-year-old boy with Joubert syndrome type 10 (JBTS10). He carried the OFD1 mutation p.Gln886Lysfs*2 (NM_003611.2: c.2656del) and manifested features of Joubert syndrome.

METHODS: We integrated exome sequencing, MALDI-TOF mass spectrometry analyses of plasma and cultured dermal fibroblasts glycomes, and full clinical evaluation of the proband. Analyses of cilia formation and lectin staining were performed by immunofluorescence. Measurement of cellular nucleotide sugar levels was performed with high-performance anion-exchange chromatography with pulsed amperometric …

Reliability And Validity Of The Hd-Pro-Triadtm, A Health-Related Quality Of Life Measure Designed To Assess The Symptom Triad Of Huntington's Disease., Nicholas R Boileau, Julie C Stout, Janes S Paulsen, David Cella, Michael K Mccormack, Martha A Nance, Samuel Frank, Jin-Shei Lai, Noelle E Carlozzi

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Huntington's disease (HD), is a neurodegenerative disorder that is associated with cognitive, behavioral, and motor impairments that diminish health related quality of life (HRQOL). The HD-PRO-TRIADTM is a quality of life measure that assesses health concerns specific to individuals with HD. Preliminary psychometric characterization was limited to a convenience sample of HD participants who completed measures at home so clinician-ratings were unavailable.

OBJECTIVES: The current study evaluates the reliability and validity of the HD-PRO-TRIADTM in a well-characterized sample of individuals with HD.

METHODS: Four-hundred and eighty-two individuals with HD (n = 192 prodromal, n = 193 early, and n …

Analyzing The Phenotypic Effect Of Three Candidate Genes Associated With Nonsyndromic Craniosynostosis Using A Zebrafish Model, Megan A. Hept

Theses and Dissertations

In normal cranial suture development, the cranial sutures close at predetermined periods of development to allow the brain the capability to grow in a malleable environment. However, in craniosynostosis, cranial sutures prematurely fuse before birth which can lead to a wide range of developmental issues and complications. Craniosynostosis can be categorized as nonsyndromic which involves the sole fusion of one or more of the cranial sutures, or syndromic in which cranial sutures fuse as well as other abnormalities associated with a genetic disorder. Past research has identified three candidate genes that could be possible disease causing mutations in nonsyndromic sagittal …

Promotion Of Early Pediatric Hearing Detection Through Patient Navigation, Matthew L. Bush

Theses and Dissertations--Clinical and Translational Science

Congenital hearing loss is the most common neonatal sensory disorder and it is crucial to diagnose hearing loss as soon as possible after birth in order to facilitate rapid treatment. Universal standards of infant hearing healthcare dictate that infant hearing screening should be completed by one month of age and abnormal screening tests should be followed with definitive audiological testing by three months of age. Obtaining diagnostic testing can be complicated by limited access to care in rural areas, breakdowns in communication, lack of parental support, and poor coordination of care. There is no established method to address appointment non-adherence …

Immunodeficiency-Associated Lymphoid Hyperplasia As A Cause Of Intussusception In A Case Of Activated Pi3k-Δ Syndrome., Daniel Mettman, Isabelle Thiffault, Chitra Dinakar, Carol J. Saunders

Manuscripts, Articles, Book Chapters and Other Papers

Activated PI3K-δ syndrome refers to a recently described primary immunodeficiency syndrome consisting of recurrent sinopulmonary infections, lymphadenopathy, mucosal lymphoid aggregates, increased susceptibility to Epstein-Barr virus and cytomegalovirus, and increased incidence of B-cell lymphomas. Variants in PIK3CD, which encodes the phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit delta isoform, enhance membrane association and kinase activity, resulting in increased signal transduction through the PI3K-Akt pathway. Whole-exome sequencing revealed a pathogenic PIK3CD variant in a patient with history of immunologic impairment, recurrent sinopulmonary infections, and lymphoid hyperplasia presenting as intussusception. This case illustrates that while lymphoid hyperplasia secondary to immunodeficiency is most often unsurprising and …

Speckle-Tracking Echocardiographic Measures Of Right Ventricular Diastolic Function Correlate With Reference Standard Measures Before And After Preload Alteration In Children., Shahryar M. Chowdhury, Suma Goudar, G Hamilton Baker, Carolyn L. Taylor, Girish S. Shirali, Mark K. Friedberg, Andreea Dragulescu, Karen S. Chessa, Luc Mertens

Manuscripts, Articles, Book Chapters and Other Papers

The accuracy of echocardiographic measures of right ventricular (RV) diastolic function has been sparsely studied. Our objective was to evaluate the correlation between echocardiographic and reference standard measures of RV diastolic function derived from micromanometer pressure analysis before and after preload alteration in children. Echocardiograms and micromanometer pressure analyses were prospectively performed before and after fluid bolus in children undergoing right heart catheterization. The isovolumic relaxation time constant (τ) and end-diastolic pressure (EDP) were measured. Conventional and speckle-tracking echocardiographic (STE) parameters of RV systolic and diastolic function were assessed. Normal saline bolus was given to increase RV EDP by 20 …

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts

Williams Honors College, Honors Research Projects

Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.

Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

A Singleton Infant With Bilateral Renal Agenesis And Normal Pulmonary Function., Lovya George, Winston M. Manimtim, Jotishna Sharma

Manuscripts, Articles, Book Chapters and Other Papers

Bilateral renal agenesis leads to anhydramnios and other sequelae including pulmonary hypoplasia. There have been rare case reports of normal pulmonary function in the presence of bilateral renal agenesis in monoamniotic discordant twins, but this has never been reported in a singleton pregnancy. The few reported cases in twins have all been fatal in the neonatal period with no reported cases of survival beyond 2 months. We describe the first case of a singleton infant with bilateral renal agenesis who had normal pulmonary function and did well on peritoneal dialysis for 4 years while awaiting a renal transplant.

Schultz, Lu Chen, Alicia Kunin-Batson, Zhengjia Chen, William G. Woods, A S. Gamis, Toana Kawashima, Kevin C. Oeffinger, H Stacy Stacy Nicholson, Joseph P. Neglia

Manuscripts, Articles, Book Chapters and Other Papers

Survival rates for children with Down syndrome (DS) and acute myeloid leukemia (AML) are high; however, little is known regarding the health-related quality of life (HR-QOL) of these survivors. Individuals who survived ≥5 years following diagnosis of childhood AML were invited to complete parent or patient-report surveys measuring HR-QOL and chronic health conditions. In total, 26 individuals with DS had a median age at diagnosis of 1.8 years (range, 0.77 to 10.9 y) and median age at interview of 15 years (range, 8.3 to 27.6 y). Participants with DS and AML were compared with AML survivors without DS whose caregiver …

Spertus, Michael L. O'Byrne, Paul S. Chan, Kevin F. Kennedy, Lisa Bergersen, Andrew C. Glatz

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The association between institutional volume and outcomes has been demonstrated for cardiac catheterization among adults, but less is known about this relationship for patients with congenital heart disease (CHD) undergoing cardiac catheterization.

METHODS: Within the IMPACT registry, we identified all catheterizations between January 2011 and March 2015. Hierarchical logistic regression, adjusted for patient and procedural characteristics, was used to determine the association between annual catheterization lab volume and occurrence of a major adverse event (MAE).

RESULTS: Of 56,453 catheterizations at 77 hospitals, an MAE occurred in 1014 (1.8%) of cases. In unadjusted analysis, a MAE occurred in 2.8% (123/4460) …
