Color-Changing Device To Improve Adherence To Foley Catheter Replacement Protocols And Reduce Urinary Tract Infection Frequency, Kurt Hill, Alexander Straus, Ms, Bryn Cross, Jason M. Fields, Md

Phase 1

Background: Foley catheter-associated UTI’s (CAUTI’s) represent a driving cause of cystitis, bacteremia and sepsis in the hospital setting. Accordingly, the CDC has identified prolonged indwelling time as the foremost risk factor for CAUTI’s. However, the fundamental design of the Foley has remained unchanged for over eighty years. Hospital-specific protocols do currently exist for the removal of infection-prone catheters; however, in practice it remains commonplace for catheters to be ignored, increasing the risk of life-threatening infection. Our design process addressed this by creating a color-changing alarm device that would alert providers when a catheter has been left in beyond protocol, is …

Helping Continuing Care Retirement Communities Determine The Best Level Of Care For Each Patient, Austin Klein, Nicholas Safian, Grant Schultheis, Sopuru Ezeonu, Danielle Snyderman, Md

Phase 1

Background: The vast majority of healthcare costs are spent on the last decade of life. Older patients often have complex medical histories complicated further by physical, mental and social limitations. High levels of hospital readmittance and nonadherence further complicate care for senior adult patients. Continuing Care Retirement Communities (CCRCs) are long term care facilities that attempt to support this diverse array of problematic patients. Residents can live in several different groupings called “Levels of Care” (LOC). To maximize safety, quality of care, and patient satisfaction, it is important to place residents in the right context. This project seeks to drive …

Cognitive Changes In Patients Treated For Obstructive Sleep Apnea With Upper Airway Stimulation, Maxillomandibular Advancement, Or Expansion Sphincter Pharyngoplasty, Nicolas Zingas, Colin Huntley, Matthew Stewart, Ramez Philips Jan 2020

Cognitive Changes In Patients Treated For Obstructive Sleep Apnea With Upper Airway Stimulation, Maxillomandibular Advancement, Or Expansion Sphincter Pharyngoplasty, Nicolas Zingas, Colin Huntley, Matthew Stewart, Ramez Philips

Phase 1

Introduction: Obstructive sleep apnea (OSA) is a prevalent diagnosis that has been shown to not only affect sleepiness, but daytime cognitive function — specifically attention, working memory, and executive function. CPAP treatment is troublesome for some patients and it is possible that superior treatment options, specifically novel surgical techniques, are available, though none have been evaluated for their long-term effects on neurocognition. We hypothesize that treating patients with upper airway stimulation surgery (UAS) UAS, maxillomandibular advancement surgery (MMA), and expansion sphincter pharyngoplasty surgery (ESP) for OSA produces a significant improvement in cognition from baseline.

Methods: For inclusion in the study, …


Assessing The Temporality Of Adverse Effects Of Vaccines In The Nicu, Julia Tonnessen, Pedro Urday, Md Jan 2020

Assessing The Temporality Of Adverse Effects Of Vaccines In The Nicu, Julia Tonnessen, Pedro Urday, Md

Phase 1

Introduction: Premature infants have an increased risk of contracting vaccine-preventable diseases and experience worse outcomes. Evidence supports keeping them on a regular vaccination schedule, but it is often delayed, partly because preterm infants have an increased incidence of cardiorespiratory events compared to term infants. The aim of our study was to determine if immunizations in the NICU contribute to an increased number of adverse events.

Methods: This was a retrospective, single-center, observational study with the target population infants born at less than 32 weeks gestation at Thomas Jefferson University Hospital who received the two-month vaccination series in the NICU. The …

Phenotype-Genotype Correlations In Patients With Epidermolysis Bullosa With Plec Mutations, Elizabeth Zhang, Masoomeh Faghankani, Hassan Vahidnezhad, Jouni Uitto

Phase 1

Epidermolysis bullosa (EB) is a heterogeneous group of genetic disorders characterized by blistering skin and mucous membranes. Mutations of the protein plectin, encoded by PLEC, cause autosomal recessive EB simplex with muscular dystrophy (EBS-MD) and EB simplex with pyloric atresia (EBS-PA). Until now, no clear genotype-phenotype correlation has been identified from the positions of mutations in the PLEC gene. How do ten distinct families with PLEC mutations manifesting as various EB disorders compare with regard to gene mutations? The hypothesis is that clinical manifestations of EB will be more extreme in patients with more severe gene mutations.
