Development Of A Method Using Retrograde Neuronal Tracers To Neuroanatomically Characterize Respiratory Neural Circuitry, Samantha Thomas, Angelo Lepore

Phase 1

Introduction:

Loss of respiratory function is one of the leading causes of death following spinal cord injury (SCI). Existing studies have demonstrated that pre-phrenic interneurons (PPIN’s) can be recruited into the phrenic motor neuron (PhMN) pathway following cervical SCI and may contribute to respiratory recovery, but there is still a lack of information detailing the nature of these changes and the extent they may improve diaphragm function. This project aims to validate a method of utilizing neuronal tracers to further characterize the intact respiratory circuitry.

Methods:

This study was carried out using a rat model. A fluorophore-conjugated retrograde neuronal …

PROMs were measured, specifically the Oswestry Disability Index (ODI), preoperatively and 6 months postoperatively. Clinical outcomes …

Evaluating The Effect Of Telestroke Intervention On Patient Treatment And Outcomes, Charles Morse, Daniel Moylan, Daniel Joffe, Michael Knapp, Ahmad Sweid

Phase 1

Acute ischemic strokes (AIS) are a prominent cause of death and have the potential to cause lifelong neurological deficits. We hypothesize that through telestroke intervention, patients will receive treatment more rapidly and therefore have reduced complications as a result of AIS. To analyze the efficacy of telestroke intervention, we completed a retrospective chart review of suspected AIS patients at hospitals in the greater Philadelphia region from 2015-2019. We then assessed whether a patient received a telestroke consultation and any subsequent care. Several variables were then used to determine the effectiveness of this intervention, such as the promptness of treatment, length …

Peri-Operative Urodynamic Assessment Has Poor Predictive Value For Developing Post-Operative Urinary Retention, Baylor Wickes, Robert Pivec, Md, Mathew S. Austin, Md

Phase 1

Introduction: Post-operative urinary retention (POUR) following primary total joint arthroplasty (TJA) has a reported prevalence up to 35%. Risk factors for developing POUR have traditionally included surrogate markers such as the presence or absence of urologic disease. However, dynamic measurement of the renal system with post-void residual volumes (PVR) has not been investigated as a tool for assessing POUR risk.

Methods: All male TJA patients underwent an pre-operative screen for POUR, including PVR measurements, patient-derived subjective urinary retention scores, and assessment of urologic disease. This was combined with a post-operative monitoring and catheterization protocol developed in partnership with a …

The Prevalence Of Orally Administered Glucocorticoids, Generalized Pustular Psoriasis And Erythrodermic Psoriasis In The Treatment Of Adult Plaque Psoriasis Provided By U.S. Dermatologists, Katherine Awh, Kumar Nasham, Christian Albornoz, Steven Feldman, Anthony Albornoz

Phase 1

Introduction: Orally administered glucocorticoids (OAG) are not recommended for the management of plaque psoriasis (PsO) due to the classically feared outcomes of generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP). Given their widespread anecdotal use, we hypothesize that the use of OAG is not infrequent among US dermatologists and is rarely complicated by GPP or EP.

Methods: Anonymous electronic survey of 50 US dermatologists. Primary outcomes of interest were the prevalence of OAG in the management of PsO and the prevalence of GPP and EP in the context of OAG tapering.

Results: Overall, 9 out of 50 (18%) respondents …

Correlates Of Rem Sleep Without Atonia In Dream Enactment Behavior Associated With Parkinson’S Disease, Nisha Bagchi, Ritu Grewal, Abigail Quintos, Rohin Saroya

Phase 1

Introduction: Parkinson’s Disease (PD), a common neurodegenerative disease worldwide, has few reliable biomarkers. PD has been linked to REM Behavioral Disorder (RBD), a condition where patients abnormally experience REM sleep without atonia (RSWA). We aim to determine whether chin movements, a feature of RSWA, could serve as a PD biomarker. We hypothesize that those with higher RSWA are more likely to have PD.

Methods: Our study examined patients who underwent polysomnograms from 2015 onwards at the Jefferson Sleep Disorders Center. We did a retrospective EPIC chart review and compared 2 groups, those with RBD and PD (n=12) versus RBD …

Women (n=325) with a BMI > 35 kg/m2 from a tertiary academic institution, 2016 – 2019, were included to estimate the risk of large for gestational age (LGA) infants and neonatal birth weight based on maternal prepregnancy BMI and diabetic status. LGA was defined as an infant birth weight > 90th percentile. Analysis included Chi-square, t-test, multivariate logistic and linear regression.

Results: Mean birthweight did …

Understanding The Relationship Between Drug Overdose Death Rates And Socioeconomic Factors, William Duan, Dennis J. Hand

Phase 1

Drug-overdose deaths increased rapidly recently. What are the causes? We believe socioeconomical factors play critical roles. Secondary data analyses are done on the US population, using mortality-data files from the National Vital Statistics System. Deaths are grouped by race, age, sex, education and marital status. We believe that the percentage-of-total-death (PoTD) value, which equals to the number-of-overdose-deaths divided by the total-number-of-deaths in the corresponding group, more accurately reflect the severity of overdose-deaths. Analysis of 2017 data reveals that among all age groups, PoTD is highest in the age 25-34 group, with dramatic differences between white (PoTD 24%) and black (PoTD …

The Role Of Rassf5 On Cell Growth And Hippo Signaling In Rhabdomyosarcoma, Megan Garver, Lee Helman, Md, Katrina Slemmons, Phd

Phase 1

Introduction: Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood. Dysregulation of the Hippo pathway, a signaling cascade that regulates many biological processes, is associated with many human cancers. The goal of my project was to delete RASSF5, a regulator of the Hippo pathway, in RMS cells utilizing CRISPR/Cas9 and then to evaluate how the absence of RASSF5 affects RMS cell growth and Hippo signaling, with and without DNMTi Tx.

Methods: A lipofectamine transfection was performed in two different RMS cell lines, Rh30 & RD, in which two different CRIPSR/Cas9 vectors with RASSF5 guide RNA were introduced. …

Characteristics And Outcomes Of Patients Discharged Directly Home From A Medical Intensive Care Unit, Michele Fiorella, Ms, Preeyal M. Patel, Ann Zheng, Lauren Mcdonnell, Msn, Acnp, Mina Yasuoka, Msn, Erika J. Yoo, Md

Phase 1

RATIONALE: Discharging patients directly from ICUs is an increasingly common practice, largely due to decreased availability of ward beds. The purpose of this study was to describe the population and evaluate the outcomes of patients discharged directly from the MICU.

METHODS: We conducted a retrospective chart review of direct discharges to home from June 2018 to June 2019 from two MICUs. Patients were separated into two groups based on wait time (<24 hours or ≥ 24 hours) between ward transfer order and actual discharge. The primary outcome was 30-day hospital readmission. Risk was adjusted using Mortality Probability Model (MPM-III); ICU workload at admission and discharge was estimated using the nine equivalents of nursing manpower use score (NEMS). Patient characteristics were compared using t-test and Fisher exact or X².

RESULTS: There was no difference in severity-of-illness or admission NEMS between the two groups. Patients who waited <24 hours for discharge were more likely to be admitted from home. Patients who waited ≥24 hours prior to discharge had significantly longer mean hospital LOS compared to those who waited <24 hours (4.63 days vs. 2.65 days, p<0.001). There was no significant difference in 30-day readmission between patients who were discharged after waiting <24 hours vs. waiting ≥24 hours (p=0.70).

CONCLUSION: Patients who returned directly home from the MICU …

Treatment Of Persistent Air Leaks Using Endobronchial Valves, Michael Zimmerman, Cole Zingas, Achala Donuru, Scott W. Cowan, Nathaniel Evans Iii, Boyd Hehn

Phase 1

Introduction: Persistent air leaks (PAL) are from bronchopleural fistula resulting from communication between the bronchial tree and pleural space. Endobronchial valves (EBVs) are unidirectional valves placed bronchoscopically preventing airflow to the diseased lung lobe. For non-operable patients with PALs, EBVs offer a potential non-invasive treatment approach to stop air leak and allow lung healing. The purpose of this study is to retrospectively analyze EBV placement to treat non-operable adult patients with PALs.

Methods: We retrospectively analyzed all adult patients that underwent EBV placement for PAL treatment at our institution from January 2016 to June 2019. All patients failed conservative …

Late Complications Of Free Flaps In Head And Neck Microvascular Reconstruction, Swapna Vasudevan, Cory Bovenzi, Md

Phase 1

Introduction: Late free flap complications (LFFC) in head and neck reconstructive surgery occur over 72 hours postoperatively and result in flap loss in 97% of cases. Due to the rarity of LFFC, there is minimal research regarding risk factors for their development. Identifying risk factors for LFFC will result in improved monitoring of patients to prevent flap loss. This study aims to identify risk factors for the development of LFFC.

Methods: The target population of this retrospective cohort study was 116 patients who had undergone an Orbital Exenteration at Thomas Jefferson University Hospital (TJUH) and had LFFC. Data was …
