An Evaluation Of The Use Of Tranexamic Acid In The Treatment Of Bradykinin-Mediated Angioedema In The Emergency Department, Sarah Yb Kim, Carol Keller

Providence Pharmacy PGY1 Program at Providence Milwaukie and Providence Newberg Medical Centers 2021

Background

Bradykinin mediated angioedema is an overarching term that includes idiopathic angioedema, angiotensin converting enzyme inhibitor (ACEi) induced angioedema and hereditary angioedema (HAE). •This is an emergent condition that must be treated with the utmost urgency due to the fatal outcomes associated with the rapid constriction of the throat. •Bradykinin mediated angioedema is treated differently from histamine associated angioedema due to its resistance to corticosteroids and antihistamines. •HAE and ACEi induced angioedema are treated similarly but there is a lack of unanimity in the first line pharmacologic treatment. •Current treatment options include fresh frozen plasma, bradykinin-2 receptor antagonists, plasma-kallikrein inhibitors …

Using Deep Learning To Analyze Materials In Medical Images, Carson Molder

Computer Science and Computer Engineering Undergraduate Honors Theses

Modern deep learning architectures have become increasingly popular in medicine, especially for analyzing medical images. In some medical applications, deep learning image analysis models have been more accurate at predicting medical conditions than experts. Deep learning has also been effective for material analysis on photographs. We aim to leverage deep learning to perform material analysis on medical images. Because material datasets for medicine are scarce, we first introduce a texture dataset generation algorithm that automatically samples desired textures from annotated or unannotated medical images. Second, we use a novel Siamese neural network called D-CNN to predict patch similarity and build …

Evaluating Va Nurse Acceptance Of Virtual Healthcare Technology During The Coronavirus Outbreak, Francesca Bryan-Couch

Doctor of Nursing Practice Scholarly Projects

At a regional Veterans Administration (VA) hospital, nurses performing case management were unable to perform face-to-face visits with patients due to coronavirus. Care coordination and discharge planning efforts occurred through telephonic case management to preserve personal protective equipment and reduce transmission rates through social distancing. Trust and rapport between patients and nurses were reduced without personal contact. Peplau’s theory of interpersonal relations described six nurse roles and three phases of relationship development required to create therapeutic nurse-patient relationships. Connectedness was a key concept considered to be the path to a successful meaningful therapeutic nurse-patient relationship (Hrabe, 2005).

Action video gaming (AVG) experience has been found related to sensorimotor and attentional development. However, the influence of AVG experience on the development of emotional perception skills is still unclear. Using behavioral and ERP measures, this study examined the relationship between AVG experience and the ability to decode emotional faces and emotional word meanings. AVG experts and amateurs completed an emotional word-face Stroop task prior to (the pregaming phase) and after (the postgaming phase) a 1 h AVG session. Within-group comparisons showed that after the 1 h AVG session, a more negative N400 was observed in both groups of participants, …

Biopharmaceutical Characteristics Of Nifurtimox Tablets For Age- And Body Weight-Adjusted Dosing In Patients With Chagas Disease., Heino Stass, Ethel Feleder, Facundo Garcia-Bournissen, Johannes Nagelschmitz, Boris Weimann, Gustavo Yerino, Jaime Altcheh

Paediatrics Publications

Treatment of Chagas disease with nifurtimox requires age- and body weight-adjusted dosing, resulting in complex dosing instructions. Appropriate formulations are needed for precise and compliant dosing, especially in pediatric patients. We characterized the biopharmaceutical features of a standard nifurtimox 120-mg tablet and a 30-mg tablet developed to improve dose accuracy. Two open-label, randomized crossover studies were conducted in adult outpatients with Chagas disease. One study investigated whether 4 × 30-mg tablets and 1 × 120-mg tablet were bioequivalent and whether tablets can be administered as an aqueous slurry without affecting bioavailability. The second study investigated the effect of a high-calorie/high-fat …

Incorporating Adverse Childhood Experiences In Medical Student Trauma-Informed Training, Mary Catherine Minke

PCOM Capstone Projects

One of the emerging fields in public health has become how behavior and personal experiences shape the health experience. Particularly, there is interest in understanding how the environment that one lives in changes one’s biology, causing disease, and how interventions can combat this change. A 1998 study conducted by the CDC and Kaiser Health first characterized negative household environments that suffered from dysfunction or abuse and showed how this could be a leading cause of death in adults (Vincent, et al., 1998). Researchers termed these Adverse Childhood Experiences (ACEs). Since that time, additional studies have found that those who suffered …

The Association Between Age And Unrecognized And Untreated Hypertension In Children With Chronic Kidney Disease, Chloe Douglas, J Roem, Joseph Flynn, Susan Furth, Bradley A. Warady, Susan Halbach

Presentations

Background: Younger age has been associated with unrecognized hypertension (HTN) in both the general pediatric population and in children on dialysis. An increased lifetime risk of cardiovascular disease and the association of HTN with chronic kidney disease (CKD) progression make optimal treatment of elevated blood pressure (BP) a key component of CKD management. However, the role of age in the recognition and treatment of HTN in non-dialysis pediatric CKD remains unknown.

Objective: Using data from the Chronic Kidney Disease in Children (CKiD) Cohort Study, we examined the relationship between age and recognized vs. unrecognized HTN, and the frequency with which …

Carter, Howard Kilbride, Steven Pastyrnak, Charles R. Neal, Lynne Smith, Jennifer Helderman, Jennifer Check, Lynne Dansereau, Sheri A. Dellagrotta, Barry Lester

Presentations

Background: Among preterm infants, risk of poor outcomes has been linked to neonatal medical illness and neurobehavior. The combined contribution of neonatal medical morbidities and neonatal neurobehavior to 2 year outcomes has yet to be studied.

Objective: To determine associations between NICU Network Neurobehavioral Scale (NNNS) profiles, medical risk, and 2 year developmental outcomes.

Design/Methods: Multi-center study of 704 infants born <30 weeks gestation enrolled in the Neonatal Neurobehavior and Outcomes in Very Preterm Infants (NOVI) Study. NNNS were completed prior to NICU discharge and six profiles of neonatal neurobehavior were calculated by latent profile analysis. Two profiles (5 and 6) were considered atypical. Medical risk included brain injury, CLD, ROP, and NEC/sepsis. Outcomes at 2 years were Bayley Scales of Infant and Toddler Development-III (BSID-III) composite scores and Child Behavior Checklist (CBCL) T-scores. Generalized estimating equation (GEE) models were used to test the associations among NNNS profiles, neonatal medical risk, and 2 year developmental outcomes. GEE models accounted for multiple births. Covariates were research site, maternal socioeconomic status (SES), race or ethnicity, maternal primary language, partner status, maternal psychopathology, and infant sex.

Results: Follow-up data were available for 556/704 (78.9%) infants, of which 157 (28.2%) were Profile 5-6. Mother of Profile 5-6 infants were more likely to be non-English speaking and lower SES compared to Profiles 1-4 mothers (Table 1). In …

Role Of Intra-Operative Ultrasound In Brain Tumour Surgeries, Mohammad Hamza Bajwa, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

The use of intra-operative ultrasound remains a largely underutilized option in brain tumour surgeries. The widespread availability of neuronavigation may be the reason why such a useful modality has become less popular even though recent advances in ultrasound technology have greatly improved its utility. The available literature also clearly shows that it offers additional advantages especially when used with neuronavigation. Herein the authors have briefly touched upon the available literature on the role of intraoperative ultrasound in brain tumour surgeries.

The Requirements Of Immunosuppressive Therapy And Clinical Features In Patients With Myasthenia Gravis Who Undergo Thymectomy Versus Non Thymectomy Management In East Africa, Nyawara Anthony Ochola

Master of Medicine in Internal Medicine

Background: Myasthenia gravis is an acquired autoimmune neuromuscular disease leading to fatigability of skeletal muscles. The thymus produces autoantibodies that target receptors to Acetylcholine or Muscle Specific Kinase. The resultant fatigability is generalized or limited to the ocular or bulbar muscles. Therapy has been targeted to reduce the autoimmune process by use of immunosuppressive agents or by thymectomy. In the African population, MG involves younger patients, more ocular involvement, is more aggressive and more resistance to immunosuppressive therapy. Methods: We conducted a retrospective study between January 2009 and December 2019 at Aga Khan University Hospital, Nairobi. Medical records of patients …

Parental Knowledge And Attitudes Towards Food Allergy, Namuli Jane Francis

Master of Medicine in Paediatrics and Child Health

Background: Food allergy and other allergen-induced diseases are an increasing problem globally. This has been documented in studies done in Western countries as well as some parts of Africa. The prevalence of food allergy is highest during the first 2 years of life. For allergen-induced illness, avoidance of triggers and prevention of fatal reactions are the mainstay of treatment. Unnecessary withdrawal of suspected protein-rich foods at a time that is critical for children’s growth may lead to malnutrition and its related complications. This study aimed to understand the gaps in knowledge and misconceptions about food allergy among parents as these …

The Study Of High Intensity Interval Training's Effect On Enjoyment, Keali Mari

Theses/Capstones/Creative Projects

This study assessed participant’s level of enjoyment in high-intensity training over moderate intensity-training. High intensity interval training is defined as short bouts of exercise performed at a near-maximal effort with rest periods or light activity in between. High intensity interval training involves repeatedly exercising at a high intensity for 30 seconds to several minutes, separated by 1-5 minutes of recovery. This type of exercise has sparked the interest of many active people due to its decreased time commitment and the benefits it elicits. The results of this study show that high intensity interval training induces a higher enjoyment rate pre- …

Power Training Improves The Sensorimotor Cortical Oscillations In Youth With Cerebral Palsy, Morgan Busboom, Anna Reelfs, Mike Trevarrow, Brad Corr, Heidi Reelfs, Sarah Baker, Hannah Bergwell, Tony W. Wilson, Max J. Kurz

Child Health Research Institute Pediatric Research Forum

Background: Our magnetoencephalographic (MEG) brain imaging studies have shown that youth with cerebral palsy (CP) demonstrate altered sensorimotor beta (18-24Hz) cortical oscillations when controlling their leg motor actions and these anomalous cortical oscillations are linked with the extent of their mobility impairments. Current therapeutic trends for improving mobility have shifted from strength training to high-velocity power training, which has shown improvements in isokinetic strength, power production and mobility of youth with CP. However, no studies have assessed whether these clinically relevant improvements are linked with changes in the sensorimotor cortical oscillations. The objective of this study was to utilize MEG …

Novel Mouse Model For Analysis Of Macrophage Function In Neuroblastoma, Gabrielle L. Brumfield, Shelby M. Knoche, Alaina C. Larson, Brittany Poelaert, Benjamin T. Goetz, Poomy Pandey, Don W. Coulter, Joyce C. Solheim

Child Health Research Institute Pediatric Research Forum

Background: Neuroblastoma is the third most common childhood cancer and accounts for 12% of cancer-associated deaths in children under the age of 15. Patients with high risk neuroblastoma have a poor 5-year survival rate of less than 50%. Neuroblastoma tumors treated with the histone deacetylase inhibitor (HDACi) vorinostat have increased infiltration of macrophages with upregulated immune cell-surface receptors. Neuroblastoma cells release VEGF and M-CSF, which may alter intratumoral macrophage populations. VEGF has also been implicated in alteration of amyloid precursor protein family processing. Our lab demonstrated that amyloid precursor protein 2 (APLP2), a member of the amyloid precursor protein …

Evaluation Of Brain Cholesterol Metabolism After Neonatal Hypoxic-Ischemic Brain Injury, Amanda Dave, Luke Allen, Zeljka Korade, Eric Peeples

Child Health Research Institute Pediatric Research Forum

Introduction

Neonatal hypoxic-ischemic brain injury (HIBI), resulting from impaired cerebral blood flow and oxygen delivery to the brain, affects at least 1.5 per 1,000 live births each year in the United States. Altered levels of cholesterol and cholesterol metabolites have been identified in brain tissue and in serum after adult brain injury such as traumatic brain injury and stroke. We hypothesized that there would be temporal and brain region-specific alterations in cholesterol and sterol precursors after neonatal HIBI.

Methods

Postnatal day 9 CD1 mouse pups were anesthetized with isoflurane and randomized to HIBI induced by carotid artery ligation or controls …

Comparison Of Postoperative Pain Scores Following Bilateral Erector Spinae Versus Bilateral Transversus Abdominis Plane Blocks In Parturients Undergoing Elective Caesarean Delivery Under Spinal Anaesthesia At The Aga Khan University Hospital, Nairobi, Rawlings Thuranira

Master of Medicine in Anaesthesiology

Background: Good pain control following lower segment caesarean section (LSCS) is essential to facilitate early mobilization and to enable adequate care of the new-born by the mother. Inadequate analgesia after caesarean delivery has been associated with increased incidences of deep venous thrombosis, chronic pain, greater opioid use and postpartum depression. Peripheral or trunk nerve blocks have become popular as part of a multimodal approach, together with opioids and non-steroidal analgesics, in controlling post caesarean pain. While the transversus abdominis plane (TAP) block has emerged in recent years as the most widely performed block for post caesarean pain the novel erector …

Reducing Alarm Burden By Promoting Judicious Ordering Of Continuous Pulse Oximetry, Kathleen Berg, David Johnson, Ginny Nyberg, Andrew Ausmus, Christine Claeys, Emily Wilkinson, Nicholas Clark

Presentations

Background: Overutilization of continuous pulse oximetry (CPO) contributes to overdiagnosis and prolonged supplemental oxygen utilization. It may also negatively impact patient sleep, mobility, length of stay (LOS), and cost. Response times to actionable alarms increase with the number of non-actionable alarms. Our baseline data revealed an average of 29.6 pulse oximetry monitor alarms sounded for each admitted patient each day of their hospitalization. Most notably, 38.7% of pulse oximetry alarms were for ≥88% which is generally considered non-actionable.

Objective: We aimed to decrease both total pulse oximetry alarms per patient day and alarms for ≥88% per patient day by 20%, …

Hypercalcemia Of Malignancy Attributed To Cosecretion Of Pth And Pthrp In Lung Adenocarcinoma, Jeffrey Kroopnick, Ubaldo E. Martinez-Outshoorn, Madalina Tuluc, Caroline S Kim

Department of Medical Oncology Faculty Papers

Introduction: Hypercalcemia of malignancy (HCM) portends a very poor prognosis, and no established guidelines exist regarding its management. Most instances of HCM are due to local osteolysis or secretion of parathyroid hormone related-peptide, while less than 1% of all cases are due to ectopic secretion of parathyroid hormone.

Case report: We present an unusual case of HCM due to proposed cosecretion of both parathyroid hormone and parathyroid hormone-related protein in a 36-year-old man with a poorly differentiated lung adenocarcinoma. The patient's hypercalcemia was refractory to conventional measures, including intravenous bisphosphonate therapy (zoledronic acid), and was improved with administration of denosumab. …

Impact Of Early Tracheostomy On Neurodevelopmental Outcome Of Infants With Severe Bronchopulmonary Dysplasia Exposed To Postnatal Steroids, Amjad Taha, Gangaram Akangire, Janelle R. Noel-Macdonnell Phd, Tiffany Willis, Winston M. Manimtim

Posters

Background: BPD is associated with neurodevelopmental impairment. Tracheostomy is performed in 5-12% of severe BPD for prolonged ventilation. There is evidence that chronic ventilation with tracheostomy in severe BPD may facilitate neurodevelopment and lead to improved outcome. However, there is no consensus on the optimal timing of tracheostomy. A large multicenter study of infants with tracheostomy performed at <120 days of life had better neurodevelopmental outcomes at 18-22 months of age. Use of steroids postnatally to ameliorate the severity of BPD had been controversial due to its negative effect on neurodevelopment. To date, no data has specifically evaluated the impact of early tracheostomy on neurodevelopmental outcome of infants with severe BPD who are exposed to postnatal steroids.


Objective: To compare cognitive, language and motor scores among 3 groups of severe BPD infants who received early vs late vs no tracheostomy. Secondly, evaluate if postnatal steroids had an additive negative effect on neurodevelopmental outcomes.


Design/Methods: IRB approved retrospective cohort of …
