Acute Agitation Intervention Tool For Reduction Of Polypharmacy, Brooks J. Propst

Dissertations

Introduction: Patients with behavioral health diagnoses are among the highest risk for
aggression. For pediatric patients with behavioral health needs, urgent treatment is
needed for aggressive behavior, due to the potential unwanted outcomes. The purpose of this Quality Improvement (QI) pilot project was to implement an Acute Agitation Intervention Tool that uses the Broset Violence Checklist (BVC) to guide
pharmacological intervention for mild and moderate to severe agitation in pediatric
patients with behavioral health needs ages 8 to 18 to decrease the number of medications that patients are getting per agitation event over a 12-week period.

Methods: This QI included …

Extubation Readiness Test in a Pediatric Cardiac Intensive Care Unit

Abstract

Problem: The lack of standard extubation readiness tests (ERTs), that are practiced in pediatric ICUs to monitor extubation readiness, clinicians have the difficult task of weighing the risk versus benefit of extubation. ERTs can aid clinicians in deciphering patients ready to be successfully extubated and have shown to decrease length of mechanical ventilation and decrease extubation failures.

Methods: The quality improvement (QI) project utilized a descriptive observational design to assess the effects of the implementation of an ERT in a pediatric cardiac ICU. This project used a convenience sample …

Potential Biomarker Of Brain Response To Opioid Antagonism In Adolescents With Eating Disorders: A Pilot Study., Stephani L. Stancil, Hung-Wen Yeh, Morgan G. Brucks, Amanda S. Bruce, Michaela Voss, Susan Abdel-Rahman, William M. Brooks, Laura E. Martin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Eating Disorders (ED) affect up to 5% of youth and are associated with reward system alterations and compulsive behaviors. Naltrexone, an opioid antagonist, is used to treat ED behaviors such as binge eating and/or purging. The presumed mechanism of action is blockade of reward activation; however, not all patients respond, and the optimal dose is unknown. Developing a tool to detect objective drug response in the brain will facilitate drug development and therapeutic optimization. This pilot study evaluated neuroimaging as a pharmacodynamic biomarker of opioid antagonism in adolescents with ED.

METHODS: Youth aged 13-21 with binge/purge ED completed functional …

Effect Of Reduced Versus Usual Lipid Emulsion Dosing On Bilirubin Neurotoxicity And Neurodevelopmental Impairment In Extremely Preterm Infants: Study Protocol For A Randomized Controlled Trial, Lindsay F Holzapfel, Cody Arnold, Jon E Tyson, Steven M Shapiro, Eric W Reynolds, Claudia Pedroza, Emily K Stephens, Alan Kleinfeld, Andrew H Huber, Matthew A Rysavy, Maria Del Mar Romero Lopez, Amir M Khan

Faculty, Staff and Student Publications

BACKGROUND: Bilirubin neurotoxicity (BN) occurs in premature infants at lower total serum bilirubin levels than term infants and causes neurodevelopmental impairment. Usual dose lipid infusions in preterm infants may increase free fatty acids sufficiently to cause bilirubin displacement from albumin, increasing passage of unbound bilirubin (UB) into the brain leading to BN and neurodevelopmental impairment not reliably identifiable in infancy. These risks may be influenced by whether cycled or continuous phototherapy is used to control bilirubin levels.

OBJECTIVE: To assess differences in wave V latency measured by brainstem auditory evoked responses (BAER) at 34-36 weeks gestational age in infants born …

Bronchiectasis Assessment In Primary Ciliary Dyskinesia: A Non-Invasive Approach Using Forced Oscillation Technique, Wilfredo De Jesús-Rojas, Luis Reyes-Peña, José Muñiz-Hernández, Patricia Quiles Ruiz De Porras, Jesús Meléndez-Montañez, Marcos J Ramos-Benitez, Ricardo A Mosquera

Faculty, Staff and Student Publications

Primary ciliary dyskinesia (PCD) is an autosomal recessive disorder that results from the dysfunction of motile cilia, which can cause chronic upper and lower respiratory infections leading to bronchiectasis. However, there is a need for additional tools to monitor the progression of bronchiectasis in PCD. The forced oscillation technique (FOT) is an effort-independent lung function test that can be used to evaluate respiratory mechanics. In this retrospective study, we aimed to describe the radiographic findings associated with respiratory impedance (resistance (Rrs) and reactance (Xrs)) measured by FOT in six adult PCD patients and one pediatric with the (

Onchocerciasis remains a debilitating neglected tropical disease. Due to the many challenges of current control methods, an effective vaccine against the causative agent Onchocerca volvulus is urgently needed. Mice and cynomolgus macaque non-human primates (NHPs) were immunized with a vaccine consisting of a fusion of two O. volvulus protein antigens, Ov-103 and Ov-RAL-2 (Ov-FUS-1), and three different adjuvants: Advax-CpG, alum, and AlT4. All vaccine formulations induced high antigen-specific IgG titers in both mice and NHPs. Challenging mice with O. volvulus L3 contained within subcutaneous diffusion chambers demonstrated that Ov-FUS-1/Advax-CpG-immunized animals developed protective immunity, durable for …

Supporting Motor, Cognitive, And Psychosocial Functions For Children And Youth With Acquired Brain Injury: A Scoping Review, Quandra Shanks, Angela Labrie Blackwell

Summer 2023 Virtual OTD Capstone Symposium

Acquired brain injury (ABI) refers to an injury to the brain that is not hereditary, congenital, degenerative, or induced by birth trauma (Brain Injury Association [BIA], 2023). ABI is an umbrella term for all brain injuries, typically classified as traumatic (e.g., sports injury, fall) or non-traumatic (e.g., stroke, infection) (Wales et al., 2021). It is considered one of the leading causes of death and disability for individuals of all ages (Riccardi & Lundine, 2022). The BIA (2023) reports that ages 0-4 and 15-19 are at greater risk for brain injury. The severity of ABI among pediatrics is more severe than …

Recognizing And Reporting Of Child Maltreatment In A Pediatric Primary Care Setting., Jennifer L. Dumey

Doctor of Nursing Practice Papers

Child abuse and neglect, together known as child maltreatment, is a global problem with grim lifelong consequences (WHO, n.d.). Education and confidence in reporting child maltreatment are imperative for medical providers who are responsible for the evaluation of children during routine visits with pediatric providers. Research continues to link child maltreatment with adverse health outcomes that span throughout a person's lifetime. For this reason, medical providers must be provided with continued education on early recognition and reporting of concerns for child maltreatment.

The purpose of this project is to increase provider knowledge on the identification and reporting of child maltreatment. …

Cost-Effectiveness Of Hydroxyurea For Sickle Cell Anemia In A Low-Income African Setting: A Model-Based Evaluation Of Two Dosing Regimens, David Teigen, Robert Opoka, Phillip Kasirye, Catherine Nabaggala, Heather A. Hume, Bjørn Blomberg, Chandy John, Russell Ware, Bjarne Robberstad

Paediatrics and Child Health, East Africa

Background and Objective: The disease burden of sickle cell anemia (SCA) in sub-Saharan African (SSA) countries is substantial, with many children dying without an established diagnosis or proper treatment. The global burden of SCA is increasing each year, making therapeutic intervention a high priority. Hydroxyurea is the only disease-modifying therapy with proven feasibility and efcacy suitable for SSA; however, no one has quantifed the health economic implications of its use. Therefore, from the perspective of the health care provider, we estimated the incremental cost-efectiveness of hydroxyurea as a fxed-dose regimen or maximum tolerated dose (MTD) regimen, versus SCA care without …

Developing And Testing A Clinical Care Bundle Incorporating Caffeine Citrate To Manage Apnoea Of Prematurity In A Resource-Constrained Setting: A Mixed Methods Clinical Feasibility Study Protocol, Grace Irimu, Ferdinand Okwaro, Jesse Coleman, Mary Waiyego, Dorothy Chomba, Millicent Parsimei, Cynthia Shitote, Roseline Ochieng, Jasmit Shah, William Macharia

Paediatrics and Child Health, East Africa

Background Apnoea of prematurity (AOP) is a common condition among preterm infants. Methylxanthines, such as cafeine and aminophylline/theophylline, can help prevent and treat AOP. Due to its physiological benefts and fewer side efects, cafeine citrate is recommended for the prevention and treatment of AOP. However, cafeine citrate is not available in most resource-constrained settings (RCS) due to its high cost. Challenges in RCS using caffeine citrate to prevent AOP include identifying eligible preterm infants where gestational age is not always known and the capability for continuous monitoring of vital signs to readily identify apnoea. We aim to develop an evidencebased …

Posture Care Management In School Based Settings For Children With Complex Physical Disabilities, Sabrina Rodriguez, Mary Jan Greer, Lee Ann Hoffman

Summer 2023 Virtual OTD Capstone Symposium

Posture care management (PCM) is an intervention that helps protect a person’s body through different positions within different contexts. PCM is not a singular direct intervention as each person is different and has different needs. This process is especially important for those who cannot reposition themselves such as children with complex physical disabilities. These children rely mainly for caregivers and school staff this process since home and school are the main places they spend the beginning years of their lives. Therefore, it is important to educate caregivers and school staff on the guidelines of proper PCM to promote health, well-being, …

Faculty, Staff and Student Publications

BACKGROUND: Difficult facemask ventilation is perilous in children whose tracheas are difficult to intubate. We hypothesised that certain physical characteristics and anaesthetic factors are associated with difficult mask ventilation in paediatric patients who also had difficult tracheal intubation.

METHODS: We queried a multicentre registry for children who experienced "difficult" or "impossible" facemask ventilation. Patient and case factors known before mask ventilation attempt were included for consideration in this regularised multivariable regression analysis. Incidence of complications, and frequency and efficacy of rescue placement of a supraglottic airway device were also tabulated. Changes in quality of mask ventilation after injection of a …
