School Based Pediatric Asthma Surveillance In Massachusetts, Frances Medaglia, Vannalyn Abille 2017 Massachusetts Department of Public Health

School Based Pediatric Asthma Surveillance In Massachusetts, Frances Medaglia, Vannalyn Abille

Community Engagement and Research Symposia

Asthma remains one of the most common chronic diseases among children in the United States today. Surveillance is limited to national and state estimates which can vary over time and by population (CDC/NCHS, National Health Interview Survey, 2012). It is estimated that anywhere from 14% to 50% of children with asthma remain undiagnosed. The Massachusetts Department of Public Health's Bureau of Environmental Health (MDPH/BEH) has been conducting a successful and comprehensive statewide school-based asthma surveillance program since 2002. Partnering with school nurses throughout the state, we request aggregate information via a one-page survey. The survey is distributed ...

Background Worldwide, oral sucrose is standard of care in many neonatal intensive care units to relieve procedural pain in neonates. This study aims to determine if time interval between sucrose administration and heelstick correlates with pain scores.

Methods Neonates were prospectively studied with variable time intervals and assessed with the Premature Infant Pain Profile-Revised (PIPP-R).

Results 150 neonates were included with a median gestational age of 30+6 (IQR 27+6–33+2) weeks and a median time interval of 72 (IQR 39–115) seconds between sucrose administration and heelstick. In multiple regression analysis, this time interval was not significantly ...

The medial subnucleus of the amygdala (MeA) plays a central role in processing sensory cues required for innate behaviors. However, whether there is a link between developmental programs and the emergence of inborn behaviors remains unknown. Our previous studies revealed that the telencephalic preoptic area (POA) embryonic niche is a novel source of MeA destined progenitors. Here, we show that the POA is comprised of distinct progenitor pools complementarily marked by the transcription factors Dbx1 and Foxp2. As determined by molecular and electrophysiological criteria this embryonic parcellation predicts postnatal MeA inhibitory neuronal subtype identity. We further find that Dbx1-derived and ...

Ux007 For The Treatment Of Long Chain-Fatty Acid Oxidation Disorders: Safety And Efficacy In Children And Adults Following 24weeks Of Treatment., J Vockley, B Burton, G T Berry, N Longo, J Phillips, Pranoot Tanpaiboon, +several additional authors 2017 George Washington University

Ux007 For The Treatment Of Long Chain-Fatty Acid Oxidation Disorders: Safety And Efficacy In Children And Adults Following 24weeks Of Treatment., J Vockley, B Burton, G T Berry, N Longo, J Phillips, Pranoot Tanpaiboon, +Several Additional Authors

Pediatrics Faculty Publications

BACKGROUND: Long-chain fatty acid oxidation disorders (LC-FAOD) lead to accumulation of high concentrations of potentially toxic fatty acid intermediates. Newborn screening and early intervention have reduced mortality, but most patients continue to experience frequent hospitalizations and significant morbidity despite treatment. The deficient energy state can cause serious liver, muscle, and heart disease, and may be associated with an increased risk of sudden death. Triheptanoin is a medium odd-chain fatty acid. Anaplerotic metabolites of triheptanoin have the potential to replace deficient tricarboxylic acid (TCA) cycle intermediates, resulting in net glucose production as a novel energy source for the treatment of LC-FAOD ...

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 ...


Environmentally-Mediated Epigenetic Effects: Uncovering The Fertile Soil In The Development Of Pediatric Cancer, Ahmed Mohammed Morsy, Eman Ahmed Hasan, Ameer Mohammed Abuelgheet, Ahmed Salaheldeen Hassan 2017 Assiut University, South Egypt Cancer Institute, Department of Pediatric Oncology

Environmentally-Mediated Epigenetic Effects: Uncovering The Fertile Soil In The Development Of Pediatric Cancer, Ahmed Mohammed Morsy, Eman Ahmed Hasan, Ameer Mohammed Abuelgheet, Ahmed Salaheldeen Hassan

Dr/ Ahmed Mohammed Morsy

Environmentally-induced epigenetic changes of gene regulation could result from chronic, lifelong exposure, to low doses of environmental toxicants, such as chemicals including, tobacco smoking and endocrine disrupting compounds, or to other environmental factors such as nutritional changes, and lifestyle-related conditions. These environmentally-acquired epigenetic marks may influence the control of gene regulation through DNA methylation, histone modification, or through a large set of non-coding RNAs (ncRNAs). These epigenetic effects might be passed on to the developing embryo and child as inheritable non-genetic marks, which recapitulate previous lifelong history of exposure to environmental influences that start from the stage of primordial germ ...

Developing Morally Sensitive Policy In The Nicu: Donation After Circulatory Determination Of Death, Michael Van Manen, Nicole Kain

The Qualitative Report

Policy development is an important activity for the practice of healthcare. Policies, after all, may cultivate common practices and ensure that best available evidence is employed in clinical decision making. Qualitative research and individuals with expertise in qualitative research methods have much to offer policy makers. We were confronted with the situation of developing policy for donation after circulatory death (DCD) for our newborn intensive care program. Due the moral-ethical complexities surrounding DCD, and the limited experience with DCD in this context, we approached policy development from an iterative design perspective employing qualitative methods. We describe our experience in employing ...

Distinct Neural Bases Of Disruptive Behavior And Autism Symptom Severity In Boys With Autism Spectrum Disorder., Y.J. Daniel Yang, Denis G Sukhodolsky, Jiedi Lei, Eran Dayan, Kevin A. Pelphrey, Pamela Ventola

Pediatrics Faculty Publications

BACKGROUND: Disruptive behavior in autism spectrum disorder (ASD) is an important clinical problem, but its neural basis remains poorly understood. The current research aims to better understand the neural underpinnings of disruptive behavior in ASD, while addressing whether the neural basis is shared with or separable from that of core ASD symptoms.

METHODS: Participants consisted of 48 male children and adolescents: 31 ASD (7 had high disruptive behavior) and 17 typically developing (TD) controls, well-matched on sex, age, and IQ. For ASD participants, autism symptom severity, disruptive behavior, anxiety symptoms, and ADHD symptoms were measured. All participants were scanned while ...

In many developing countries, concerted action against common childhood infectious diseases has resulted in remarkable reduction in infant and under-five mortality. As a result, pediatric cardiovascular diseases are emerging as a major contributor to childhood morbidity and mortality. Pediatric cardiac surgery and cardiac catheterization interventions are available in only a few of Sub-Saharan African countries. In Uganda, open heart surgeries (OHSs) and interventional procedures for pediatric cardiovascular disease are only possible at the Uganda Heart Institute (UHI), having been started with the help of expatriate teams from the years 2007 and 2012, respectively. Thereafter, independent OHS and cardiac catheterization have ...

PURPOSE: High intensity focused ultrasound (HIFU) is a non-invasive therapeutic technique that can thermally ablate tumors. Boiling histotripsy (BH) is a HIFU approach that can emulsify tissue in a few milliseconds. Lesion volume and temperature effects for different BH sonication parameters are currently not well characterized. In this work, lesion volume, temperature distribution, and area of lethal thermal dose were characterized for varying BH sonication parameters in tissue-mimicking phantoms (TMP) and demonstrated in ex vivo tissues.

METHODS: The following BH sonication parameters were varied using a clinical MR-HIFU system (Sonalleve V2, Philips, Vantaa, Finland): acoustic power, number of cycles/pulse ...


Promotion Of Skin Protection In Children In Waterbury, Vt, Kelsey M. Sullivan 2017 University of Vermont College of Medicine

Promotion Of Skin Protection In Children In Waterbury, Vt, Kelsey M. Sullivan

Family Medicine Block Clerkship, Student Projects

Background: Vermont has among the highest rates of skin cancer in the nation. Between 2001 and 2005, Vermont had the highest incidence of melanoma of any state, 63% higher than the national average. It is also estimated that if children under 18 regularly used sunscreen of at least SPF 15, the incidence of squamous and basal cell carcinomas would decrease by 78%. Modeling by the EPA and CDC suggests that recommended sun protection measures could prevent 11,000 cases of skin cancer, 50 deaths, and $30 million in cancer treatment costs nationwide. Intervention: To create an information sheet on skin ...

Nasopharyngeal Microbiome Diversity Changes Over Time In Children With Asthma, Marcos Pérez-Losada, Lamia Alamri, Keith Crandall, Robert J. Freishtat

Pediatrics Faculty Publications

Background

The nasopharynx is a reservoir for pathogens associated with respiratory illnesses such as asthma. Next-generation sequencing (NGS) has been used to characterize the nasopharyngeal microbiome of infants and adults during health and disease; less is known, however, about the composition and temporal dynamics (i.e., longitudinal variation) of microbiotas from children and adolescents. Here we use NGS technology to characterize the nasopharyngeal microbiomes of asthmatic children and adolescents (6 to 18 years) and determine their stability over time.

Methods

Two nasopharyngeal washes collected 5.5 to 6.5 months apart were taken from 40 children and adolescents with asthma ...
