Acute Stress Disorder And Post-Traumatic Stress Disorder Screening In Pediatric Trauma Patients, Samantha Irizarry, Marian Malone, Megan Waddell

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

BACKGROUND: Two-thirds of U.S. children and adolescents report experiencing one or more potentially traumatic events by age seventeen. 13.4% of the North Carolina pediatric population ages 0-17 have undergone two or more traumatic adverse childhood experiences, compared to 14% of the U.S. population. Early identification reduces the by-products of underdiagnosis of ASD and PTSD, such as mental illness, developmental delays, poor academic performance, and challenges with social interactions.

LOCAL PROBLEM: The project site is a level-one pediatric trauma hospital in Charlotte, North Carolina, seeing more than 130,000 patients annually. Before project implementation, there was an absence of ASD …

"My Gut Feeling Is…": An Ethnographic Study Exploring Interprofessional Communication About Children And Adolescents With Chronic Musculoskeletal Pain In Paediatric Rheumatology., Rebecca R. Lee, Janet E. Mcdonagh, Tim Rapley, Albert Farre, Mark Connelly, Tonya M. Palermo, Karine Toupin-April, Emily Wakefield, Sarah Peters, Lis Cordingley

Manuscripts, Articles, Book Chapters and Other Papers

Interprofessional communication about inflammatory and non-inflammatory musculoskeletal conditions is an important component of assessment and management in paediatric rheumatology. Chronic pain is a feature of some of these conditions which likely influences the extent and type of communication about pain. Research investigating interprofessional communication about paediatric pain is limited but has found that communication is inclusive of the biopsychosocial context of children/adolescents as well as their families. The aim of this ethnographic study was to explore interprofessional communication about children and adolescents with chronic musculoskeletal pain in paediatric rheumatology. We observed forty-five healthcare professionals recruited from 3 UK paediatric rheumatology …

Barriers To The Diagnosis, Care, And Management Of Pediatric Patients With Ehlers-Danlos Syndrome In The United States: A Qualitative Analysis., William R. Black, Lora L. Black, Jordan T. Jones

Manuscripts, Articles, Book Chapters and Other Papers

Objectives: Ehlers-Danlos Syndromes (EDS) are a family of heritable connective tissue diseases. Primary practitioners are capable of diagnosing and managing EDS; however, few are knowledgeable and comfortable enough to see patients with EDS, resulting in delays in diagnosis and care. This study explores the barriers physicians experience with diagnosing, managing, and caring for patients with EDS, and potential resolutions to those barriers. Methods: As part of a larger online study, providers (n = 107) in the United States were asked to specify "What information would improve (their) comfort" in diagnosing, caring for, and managing EDS via open-ended questions. Results …

Department of Medical Oncology Faculty Papers

Lymphomas are not infrequently associated with the Epstein-Barr virus (EBV), and EBV positivity is linked to worse outcomes in several subtypes. Nanatinostat is a class-I selective oral histone deacetylase inhibitor that induces the expression of lytic EBV BGLF4 protein kinase in EBV+ tumor cells, activating ganciclovir via phosphorylation, resulting in tumor cell apoptosis. This phase 1b/2 study investigated the combination of nanatinostat with valganciclovir in patients aged ≥18 years with EBV+ lymphomas relapsed/refractory to ≥1 prior systemic therapy with no viable curative treatment options. In the phase 1b part, 25 patients were enrolled into 5 dose escalation cohorts to determine …

Diagnostic Criteria For Identifying Individuals At High Risk Of Progression From Mild Or Moderate To Severe Alcohol Use Disorder, Alex P Miller, Emma C Johnson, Rebecca Tillman, Vivia V Mccutcheon, Kathleen K Bucholz, Arpana Agrawal, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Current Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) (DSM-5) diagnoses of substance use disorders rely on criterion count-based approaches, disregarding severity grading indexed by individual criteria.

OBJECTIVE: To examine correlates of alcohol use disorder (AUD) across count-based severity groups (ie, mild, moderate, mild-to-moderate, severe), identify specific diagnostic criteria indicative of greater severity, and evaluate whether specific criteria within mild-to-moderate AUD differentiate across relevant correlates and manifest in greater hazards of severe AUD development.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study involved 2 cohorts from the family-based Collaborative Study on the Genetics of Alcoholism (COGA) with 7 sites …

Remote Ischaemic Conditioning Combined With Bimanual Task Training To Enhance Bimanual Skill Learning And Corticospinal Excitability In Children With Unilateral Cerebral Palsy: A Study Protocol Of A Single Centre, Phase Ii Randomised Controlled Trial, Swati M Surkar, John D Willson, Jessica M Cassidy, Shailesh Kantak, Charity G Patterson

Department of Rehabilitation Medicine Faculty Papers

INTRODUCTION: Children with unilateral cerebral palsy (UCP) have difficulty in bimanual coordination that restricts the child's independence in daily activities. Although several efficacious interventions to improve bimanual coordination exist, these interventions often require higher training doses and have modest effect sizes. Thus, there is a critical need to find an effective priming agent that, when paired with task-specific training, will facilitate neurobiological processes to enhance the magnitude of training effects and subsequently improve functional capabilities of children with UCP. The aim of this study is to determine the effects of a novel priming agent, remote ischaemic conditioning (RIC), combined with …

Progression Of Comorbidities In Youth With Overweight Or Obesity During The Covid-19 Pandemic., Erica Wee, Ashley K. Sherman, Safa Farrukh, Mark A. Clements, Kelsee Halpin, Yun Yan

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Childhood obesity rates have continued to increase with the COVID-19 pandemic. However, data are limited on the impact of increasing obesity on associated comorbidities.

METHODS: We evaluated the progression of overweight- or obesity-associated comorbidities by investigating change in laboratory results pre-COVID-19 pandemic and post-COVID-19 pandemic onset in youth with overweight or obesity. We defined progression of comorbidities based on increase in category rather than absolute change in value.

RESULTS: HbA1c progression was seen in 19%, and LDL cholesterol progression was seen in 26%, as defined by categories. HbA1c progression and LDL cholesterol progression were significantly correlated. HbA1c and LDL …

BACKGROUND: Differences in responding to sensory stimuli, including sensory hyperreactivity (HYPER), hyporeactivity (HYPO), and sensory seeking (SEEK) have been observed in autistic individuals across sensory modalities, but few studies have examined the structure of these "supra-modal" traits in the autistic population.

METHODS: Leveraging a combined sample of 3868 autistic youth drawn from 12 distinct data sources (ages 3-18 years and representing the full range of cognitive ability), the current study used modern psychometric and meta-analytic techniques to interrogate the latent structure and correlates of caregiver-reported HYPER, HYPO, and SEEK within and across sensory modalities. Bifactor statistical indices were used to …

Differential Processing Of Risk And Reward In Delinquent And Non-Delinquent Youth, Natasha Duell, Michael T Perino, Ethan M Mccormick, Eva H Telzer

2020-Current year OA Pubs

The present study examined the behavioral and neural differences in risky decision-making between delinquent (n = 23) and non-delinquent (n = 27) youth ages 13-17 years (M = 16, SD = 0.97) in relation to reward processing. While undergoing functional neuroimaging, participants completed an experimental risk task wherein they received feedback about the riskiness of their behavior in the form of facial expressions that morphed from happy to angry. Behavioral results indicated that delinquent youth took fewer risks and earned fewer rewards on the task than non-delinquent youth. Results from whole-brain analyses indicated no group differences in sensitivity to punishments …

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with excess risk of cardiovascular and thrombotic events in the early post-infection period and during convalescence. Despite the progress in our understanding of cardiovascular complications, uncertainty persists with respect to more recent event rates, temporal trends, association between vaccination status and outcomes, and findings within vulnerable subgroups such as older adults (aged 65 years or older), or those undergoing hemodialysis. Sex-informed findings, including results among pregnant and breastfeeding women, as well as adjusted comparisons between male and female adults are similarly understudied.

METHODS: Adult patients, aged ≥18 years, with polymerase chain reaction-confirmed COVID-19 …

Acceleration Profiles Of Adolescent Soccer Players Across A Season, Jake A. Melaro

Doctoral Dissertations

The injury risk inherent to soccer can be affected by external training loads and intrinsic factors. These intrinsic factors (sex, mass, strength, coordination, etc.) in young athletes can be rapidly altered the near their peak height velocity (PHV) during puberty, modifying their movement complexity and, potentially, their injury risk. While quantification of movement complexity through multiscale entropy analysis have been used in past biomechanical investigations, no studies have incorporated this analysis on tibial accelerometry signals collected in these maturing athletes. The purpose of this study is to collect tibial acceleration data from youth soccer athletes during several discrete drills and …
