Automated Assessment Of Thoracic-Abdominal Asynchrony In Patients With Morquio Syndrome., Madhavi V Ratnagiri, Yan Zhu, Tariq Rahman, Mary Theroux, Shunji Tomatsu, Thomas H Shaffer

Department of Pediatrics Faculty Papers

Morquio syndrome is a rare disease caused by a disorder in the storage of mucopolysaccharides that affects multiple organs, including musculoskeletal, respiratory, cardiovascular, and digestive systems. Respiratory failure is one of the leading causes of mortality in Morquio patients; thus, respiratory function testing is vital to the management of the disease. An automated respiratory assessment methodology using the pneuRIP device and a machine-learning algorithm was developed. pneuRIP is a noninvasive approach that uses differences between thoracic and abdominal movements (thoracic-abdominal asynchrony) during respiration to assess respiratory status. The technique was evaluated on 17 patients with Morquio (9 females and 8 …

Subject-Specific Musculoskeletal Modeling Of Hip Dysplasia Biomechanics, Ke Song

McKelvey School of Engineering Graduate Student Theses & Dissertations

Developmental dysplasia of the hip (DDH) is characterized by abnormal bony anatomy, causes pain and functional limitations, and is a prominent risk factor for premature hip osteoarthritis. Although the pathology of DDH is believed to be mechanically-induced, little is known about how DDH anatomy alters hip biomechanics during activities of daily living, partly due to the difficulties with measuring hip muscle and joint forces. Musculoskeletal models (MSMs) are useful for dynamic simulations of joint mechanics, but the reliability of MSMs for DDH research is limited by an accurate model representation of the unique hip anatomy. To address such challenges, this …

Magnetic Resonance-Guided High Intensity Focused Ultrasound (Mrghifu) Induced Hyperthermia (Ht) For Treatment Of Cervical Cancer, Lifei Zhu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Hyperthermia (HT), which refers to increasing the temperature of the tumor tissue to 40–45°C for an extended period of time, has been reported to be one of the most effective sensitizers for radiation therapy (RT) and/or chemotherapy. High intensity focused ultrasound (HIFU) has been developed as a non-invasive and non-ionizing tool to induce localized HT. Magnetic resonance thermometry (MR thermometry) is one of the most reliable methods for non-invasively and precisely measuring the in vivo volumetric temperature in real time. The integration of MR thermometry with HIFU has been implemented in commercially available magnetic resonance guided high intensity focused ultrasound …

The Relationships Between Stress, Psychosocial Resources, And Mental Health And Adherence Outcomes Among Perinatally Hiv-Infected Adolescents In South Africa, Thabani Nyoni

Brown School Graduate Student Theses and Dissertations

Adolescents living with perinatally acquired HIV (APHs) in sub-Saharan Africa (SSA) constitute a significant population group that is experiencing poor HIV treatment outcomes (CIPHER Global Cohort Collaboration, 2018). Compared to younger children and older adults within the SSA sub-region, APHs experience poorer health outcomes, including retention in care, virologic treatment failure, and mortality rates (Anderson et al., 2019). Among countries in the SSA sub-region, South Africa has 360,000 adolescents living with HIV (ages 10-19), a disproportionate burden, accounting for 20% of the global adolescents living with HIV (UNAIDS, 2019a). The public health costs of suboptimal antiretroviral treatment (ART) adherence in …

The goal of this narrative review is to identify sex and gender related oral health disparities by summarizing the current literature related to differences in oral health between men and women. The review identified that men are more likely to: ignore their oral health, have poorer oral hygiene habits, and experience higher rates of periodontal disease, oral cancer, and dental trauma. Men also visit dentists less frequently and compared to women seek oral treatment more often for an acute problem and …

Use Of Artificial Intelligence To Identify Predictors Of Functional Outcomes In Patients With Facioscapulohumeral Muscular Dystrophy, Natalie K. Katz

Research Days

Background: Facioscapulohumeral muscular dystrophy (FSHD) is one of the most common forms of muscular dystrophy characterized by slowly progressive muscle weakness. Symptoms initially involve the facial and shoulder girdle muscles, with later involvement of the distal lower extremities, pelvic girdle and proximal lower extremities. FSHD type 1 (FHSD1) is the most common form (~95% of individuals) and is caused by deletion of microsatellite repeats in the D4Z4 region on chromosome 4 (4q35). Normal individuals have >10 repeats whereas individuals with FSHD1 have 1-10 repeats. There is significant variability in regards to disease severity, rates of progression and functional outcomes, but …

Financial Outcomes Of High Flow Nasal Cannula Use For Bronchiolitis On The General Pediatric Floor Across Children's Hospitals, Jonathan Hartley

Research Days

Background: Bronchiolitis is a leading cause of hospitalization for infants and results in over 1.7 billion dollars in yearly hospital charges (Hasegawa). The use of high flow nasal cannula (HFNC) on a general pediatrics floor may reduce hospital costs and length of stay (LOS, Kalburgi). However, the financial impact of HFNC use is not welldescribed.

Objective: The primary objective are the financial outcomes of HFNC utilization on the general pediatric floor. The secondary objective included financial outcomes stratified by All Patients Refined Diagnosis Related Groups (APRDRG) severity of illness (SOI) and payor type. We hypothesize that costs outweigh reimbursement for …

Factors Associated With Suicide Screenings For An Autism Spectrum Disorder Population In A Pediatric Medical Setting, Cheng Qian, Dawn Greathouse

Research Days

Background: Individuals with autism spectrum disorder (ASD) are at least 3 times more likely to attempt suicide than those without ASD (Kolves et al., 2021; Richa et al., 2014). Core features of ASD (e.g., deficits in communicating emotions, difficulty with change) are associated with known suicide attempt antecedent events, and rates of co-occurring mental health concerns (e.g., depression) that increase suicide risk are higher than in the general population (Richa et al., 2014). However, mental health clinicians perceive patients with ASD to be at lower risk for suicide, and report lower self-efficacy in screening in this population (Jager-Hyman et al., …

Characterization Of Comorbidities In Patients With A Dual Diagnosis Of Down Syndrome And Autism Spectrum Disorder Using Cerner Health Facts, Michael Slogic

Research Days

Background: Up to 19% of patients with Down syndrome (DS) meet diagnostic criteria for autism spectrum disorder (ASD) (Channell, et al, 2019). While the medical and psychological comorbidities for patients with DS or ASD are well characterized, comorbidities and outcomes for patients with a dual diagnosis (DS-ASD) are poorly understood. A large cohort of patients with DS-ASD, as well as those with ASD and DS alone, are needed to better understand this. Methods for grouping and analyzing complex diagnostic phenotypes are also needed.

Objectives/Goal: Our objective is to utilize Cerner Health Facts, a multi-institutional healthcare database, to identify large populations …

Effectiveness And Safety Of Repeat Dexamethasone For Bronchopulmonary Dysplasia, Christian Oliveros

Prevalence Of Mycoplasma Genitalium And Macrolide Resistance In Adolescent Females Receiving Care At A Pediatric Hospital, Kayla Barnes

Research Days

Background: Mycoplasma genitalium is an established sexually transmitted cause of nongonococcal urethritis in males and macrolide resistance is increasing. The pathogenic role is less well-defined in adolescent females and guidelines recommend M. genitalium testing only be considered in cases of persistent or recurrent cervicitis and pelvic inflammatory disease (PID). We lack understanding of the prevalence and macrolide resistance of M. genitalium among adolescent females.

Objectives/Goal: To determine the prevalence of M. genitalium and rate of detected macrolide resistance among adolescent females seeking care at a pediatric children’s hospital.

Methods/Design: We collected 200 salvaged urogenital samples (56 urine and 144 vaginal) …

Infliximab As Rescue Therapy In Pediatric Severe Colitis, Kayla B. Briggs

Research Days

Background: Infliximab has been shown to be effective in achieving clinical remission in patients with ulcerative colitis (UC) refractory to conventional therapy. However, there is conflicting data in the literature regarding its effectiveness as rescue therapy in acute severe colitis. Furthermore, most studies were conducted in adults, and pediatric onset of inflammatory bowel disease (IBD) is associated with more severe disease that may be less amenable to rescue therapy.

Objectives/Goal: We reviewed our experience with pediatric severe colitis and report outcomes following attempted rescue therapy with infliximab.

Methods/Design: A retrospective review was conducted of patients with UC or indeterminate colitis …

A Study Examining The Safety And Efficacy Of Ferric Carboxymaltose In A Large Pediatric Cohort, Chandni Dargan Md, David Simon Do

Research Days

Background: Iron deficiency anemia (IDA) is common in the pediatric population with varying high-risk factors. Intravenous (IV) iron supplementation has become more desirable in patients with moderate to severe anemia and in patients who are either unresponsive to or have adverse side-effects secondary to oral iron. Iron sucrose and Iron dextran have been traditionally used in pediatrics while ferric carboxymaltose (FCM) has only been FDA approved in adults. One of the major advantages of FCM is the ease of dosing and efficacy. Though FCM was approved for adults in 2013 and there have been no safety concerns, it is not …

Neonatal Arch Obstruction: Not Always A Coarctation, Karoline Krzywda

Research Days

Background: Spontaneous neonatal arch thrombosis is a rare, highly lethal cause of aortic arch obstruction.

Case: A 1-day-old male infant presented failing CCHD screen, on prostaglandin infusion for echocardiographic concerns of aortic coarctation. Repeat echocardiogram revealed severe arch obstruction due to a large, 7.5x5mm echogenic mass, at the aortic isthmus (Fig1A) with right to left systolic PDA flow. CT angiography confirmed presence of a large aortic arch thrombus (Fig1B). Bivalirudin infusion was initiated without change in thrombus size after 2 days. Tissue plasminogen activator (tPA) was subsequently administered with significant reduction in thrombus size to 3x4mm (Fig1C) on day 1 …

Unique Evaluation And Management Considerations For Adolescents With Late Gynecologic And Colorectal Issues In The Setting Of Anorectal Malformations, Wendy Jo Svetanoff

Research Days

Background: Females born with anorectal malformations (ARMs) and bladder exstrophy have a greater incidence of Mullerian and genital anomalies requiring early gynecologic assessment and frequent surgical intervention. However, there is little guidance for management considerations of pubertally identified Mullerian anomalies in these patients

Objectives/Goal: We sought to assess the unique colorectal, gynecologic, and psychological issues present during the adolescent years.

Methods/Design: A retrospective review was performed of 10-25 year old female patients born with an ARM, cloaca, or exstrophy that presented to our multidisciplinary clinic between 2009 and 2019. Data abstracted included the presenting problem, history, imaging studies, psychological evaluation, …

Attitudes Of Pediatric Residents In The Care Of Transgender Youth, Michelle Knoll

Background: Transgender individuals have health disparities compared to the general population and face several barriers to medical care. Prior studies indicate physician knowledge on transgender topics is poor and that transphobia is associated with poor knowledge even after educational interventions. Objectives/Goal: We sought to examine pediatric residents’ attitudes about transgender individuals and assess concerns related to the treatment of transgender youth. Methods: A survey was sent to 89 US Pediatric and combined (e.g. Med-Peds) residency programs and advertised on social media. Approximately 32 programs forwarded the survey to an estimated 1325 residents; 138 residents completed it. The survey consisted of …

A Case Series Of Hyperglycemic Hyperosmolar State During The Global Covid-19 Pandemic, Benjamin Hoag

Research Days

Background: Hyperglycemic hyperosmolar state (HHS) is rare in pediatrics, particularly in patients with antibody positive diabetes mellitus (DM). Recent literature has implicated COVID-19 in the reported increase in new onset DM cases, as well as mixed diabetic ketoacidosis (DKA) and HHS cases; however, a rise in HHS cases alone has not been well reported [1,2]. We noted an anecdotal increase in the frequency of HHS cases in our pediatric tertiary care center following the onset of the global COVID-19 pandemic.

Objectives/Goal: To investigate further, a retrospective chart review evaluating all patients with DM admitted in the first 6 months of …

Portable Low Field Strength Mri: Preliminary Experience In Neonates And Children, Johnston Fite

Research Days

Background: High field strength MRI (HF-MRI) is a pediatric imaging staple. However, HF-MRI access is limited by strong (1.5 – 3.0 T) magnetic fields with associated safety concerns, space requirements, and cost. To address these limitations, Hyperfine (Guilford, CT) developed a low magnetic field (0.064 T) portable MRI device, named Swoop. Preliminary data in adults shows benefits despite decreased image quality. In this study, initial evaluation of Swoop’s image quality in pediatric patients was assessed.

Objectives/Goal: The objective in this study was the initial evaluation of Swoop’s image quality in pediatric patients to serve as a baseline.

Methods/Design: The study …

Variability In Blood Gas Levels During Non-Invasive Ventilatory Support Following Planned Extubation And Association To 36-Week Bronchopulmonary Dysplasia In Preterm Neonates, Michelle Klueppelberg

Research Days

Background: Despite shifts to non-invasive support, as of 2012, 87% of preterm infants admitted to the neonatal intensive care unit (NICU) continued to receive some form of invasive mechanical ventilation1 . As a result, research around how prolonged respiratory support may impact the development of chronic lung disease, specifically bronchopulmonary dysplasia (BPD) has flourished. To date, literature has established associations between the time on invasive mechanical ventilation and incidence BPD2,3. Resulting in the development of standardized extubation strategies and bringing with them objective measures of extubation readiness4,5. Yet, due to their volatile conditions, some neonates will inevitably need to be …

Impact Of High Flow Nasal Cannula On Resource Utilization In Bronchiolitis, Scott Biggerstaff

Research Days

Background: Bronchiolitis is one of the most common diseases requiring hospitalization in children 1-24 months of age, but presently treatment is primarily supportive. High flow nasal cannula is a newer method of oxygen delivery pediatric hospitals have been rapidly adopting to treat respiratory insufficiency caused by viral bronchiolitis.

Objectives/Goal: We sought to compare resource utilization, including cost, length of stay (LOS), and readmission among children who were treated with HFNC versus those who were not.

Methods/Design: In this cross-sectional, multicenter study, we obtained clinical and resource utilization data from the Pediatric Health Information System (PHIS) database for otherwise healthy children …

Antibiotic Durations For Skin And Soft Tissue Infections In Pediatric Urgent Care Clinics, Megan Hamner

Research Days

Background: Skin and soft tissue infections (SSTIs) are the second most common diagnosis leading to pediatric antibiotic prescriptions in the outpatient setting after respiratory diagnoses. However, most antibiotic stewardship programs have mainly focused on the latter. Children seen in the ambulatory setting for SSTIs often receive >7 days of antibiotics, although current society guidelines recommend 5-7 days for most diagnoses.

Objectives/Goal: To determine the baseline percentage of patients receiving antibiotic prescriptions for >7 days for SSTIs in Children’s Mercy urgent care clinics (UCC)s and to evaluate factors that influence providers towards longer durations.
