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

Phase 1

Introduction: Given the current era of decreasing hospital bed availability, there has been a rise in the practice of direct discharge to home (DDH) from ICUs. We evaluated the demographics, clinical characteristics, outcomes and readmission patterns among DDH patients.

Methods: Retrospective review of patients from 2 MICUs from June 2017 to June 2019 at Thomas Jefferson University hospital, an urban tertiary care center. Primary outcome of interest was 30-day hospital readmission. Patients were dichotomized into two groups based on time between ward transfer order and hospital discharge (<24 or ≥24 hours). Risk adjustment performed with Mortality Probability Model (MPM0 -III). ICU workload at admission and discharge was estimated with nine equivalents of nursing manpower use score (NEMS). Patient characteristics compared using t-test and Fisher exact or χ2 test.

Results: 331 DDH patients were analyzed, with the majority (68.3 ...

We aim to study the impact of smartphone usage on healthy pediatric patients’ fusional vergence amplitudes and report findings that may lead to future eye problems.

Methods: This is a prospective randomized study. We are currently recruiting healthy patients between the ages of 8-17 years old with no ocular problems. Data collected include refractive error, ocular alignment in the distance and at near, divergence amplitudes at near and in distance, convergence amplitudes at near and in distance ...


Late Complications Of Free Flaps In Head And Neck Microvascular Reconstruction, Swapna Vasudevan, Cory Bovenzi, MD 2020 Thomas Jefferson University

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 obtained ...

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 ...


Does Maternal Methadone Dose Correlate With Severity Of Intrauterine Growth Restriction In Infants With Neonatal Abstinence Syndrome?, D. Friedman, J. Smith, M. Lafferty, Z. H. Aghai 2020 Thomas Jefferson University

Does Maternal Methadone Dose Correlate With Severity Of Intrauterine Growth Restriction In Infants With Neonatal Abstinence Syndrome?, D. Friedman, J. Smith, M. Lafferty, Z. H. Aghai

Phase 1

Introduction : Previous studies demonstrate a relationship between maternal opioid use during pregnancy and smaller head circumference of infants with neonatal abstinence syndrome (NAS). The goal of this study is to correlate maternal methadone dose and severity of growth restriction in infants with NAS admitted to the neonatal intensive care unit (NICU).

Methods: This is a retrospective analysis of infants (≥35 weeks gestation) exposed to in utero methadone, born between August 2006 and May 2018, and admitted to a Philadelphia NICU for medical therapy for NAS. Growth parameters (birth weight, birth length, and birth head circumference) were compared between infants exposed ...

Amelioration Of The Neuroinhibitory Local Environment After Ischemic Injury Through In Situ Astrocyte-To-Neuron Conversion, Abhinav K. Rao, Yu-Chen Chen, Ning-Xin Ma, Zi-Fei Pei, Susan Keefe, Emma Yellin, Miranda Chen, Fu-Han Yang, Xiao-Song He, Gong Chen

Phase 1

Ischemic injury in central nervous system (CNS) often causes severe neuronal loss and activates glial cells. We showed earlier that NeuroD1-mediated astrocyte-to-neuron (AtN) conversion can regenerate a substantial proportion of neurons (~40% of the total) and reconstruct the ischemic injured neural circuits. In this study, we focus on glial changes and blood vessel recovery following AtN conversion. Specifically, we found that ectopic expression of NeuroD1 in the reactive astrocytes after ischemic injury significantly reduced glial reactivity, as shown by less hypertrophic morphology, along with reduced secretion of neuroinhibitory factors such as CSPG and LCN2. As for microglia, we found less ...


In Vivo T Cell Genetic Engineering With Melanoma-Specific Tcr And Car, Toby Mathew, Vitali Alexeev 2020 Thomas Jefferson University

In Vivo T Cell Genetic Engineering With Melanoma-Specific Tcr And Car, Toby Mathew, Vitali Alexeev

Phase 1

Introduction: Adoptive cell transfer (ACT) using T cells genetically engineered to express tumor-specific T cell receptors (TCR) and Chimeric Antigen receptors (CAR) have demonstrated high remission rates in patients with advanced cancers. Targeting of metastatic melanoma with TCR-modified recombinant T cells showed clinically significant response in the majority of patients. However, due to certain drawbacks, this powerful strategy is not yet available for broad clinical application. We propose that in vivo genetic engineering approach may allow overcoming several drawbacks associated ACT and could convert it into generic and cost-effective modality to bring recombinant T cell therapies to general patient population ...


Measuring The Efficacy Of Medical Management Versus Decompressive Hemicraniectomy In Acute Stroke, Colton Hemphill, Franziska Herpich, Muhammad Athar, Eunice Lee 2020 Thomas Jefferson University

Measuring The Efficacy Of Medical Management Versus Decompressive Hemicraniectomy In Acute Stroke, Colton Hemphill, Franziska Herpich, Muhammad Athar, Eunice Lee

Phase 1

Introduction: Stroke is a life-threatening condition requiring immediate treatment in order to optimize patient survival and functionality post-hospitalization. At present, the primary treatment modalities used are intensive medical management and surgical decompressive hemicraniectomy. We believe that application of skilled medical management can result in a lower mortality rate and higher functional score at 12 months than aggressive surgical decompressive hemicraniectomy.

Methods: Epic data from Thomas Jefferson University will be used to identify patients with a large stroke (as defined by ischemic area on MRI) managed by the neurology department from 2016 to 2019. A survey will be administered by phone ...

Gut Microbiome Analysis In Morphine Exposure And Naltrexone-Induced Withdrawal, Nick Rapp, Sean O'Sullivan, James Schwaber

Phase 1

Introduction and Objectives: Relatively little is understood about the underlying physiological changes that occur in the withdrawal state of opiate users. Research on the effects of alcohol withdrawal on the Gut-brain axis (GBA) has revealed shifts in relative numbers of specific bacterial species that correlate with increased central nervous system (CNS) inflammation via neurological crosstalk. The purpose of this research was to determine if similar shifts in the relative abundance of bacterial populations occur in the opiate withdrawal state.

Methods: Fourteen rats were randomized into four groups. Control and experimental rats were administered 75 mg morphine pellets or placebo (sugar ...

Myers, Md, L. J. Katz, Md, Scott Fudemberg, Md, Anand Mantravadi, Md, Natasha Kolomeyer, Md, Reza Razeghniejad, Md

Phase 1

Introduction: Uveitis is an inflammatory eye disorder which may elevate intraocular pressure (IOP), causing sight-threatening glaucoma. Treatment of refractory uveitic glaucoma involves implantation of a glaucoma drainage device (GDD). Uveitic glaucoma has been a minority diagnosis in prior studies comparing the valved Ahmed GDD and non-valved Baerveldt GDD. Here we compare the safety and efficacy of the Ahmed and Baerveldt GDD in uveitic glaucoma.

Methods: This retrospective comparative study was conducted on patients with uveitic glaucoma (≥14 years old) who underwent Ahmed or Baerveldt GDD implantation between 2006–2018 with a minimum follow-up of 3 months. Success was defined as ...

Saver, Fast-Mag Trial Investigators And Coordinators

Phase 1

Introduction: Circadian variations in stroke onset provide critical information for the allocation of pre-hospital and hospital resources in clinical care. Confining analysis to patients with defined onset in waking and clearly distinguished ischemic and hemorrhagic stroke subtypes, would substantial benefit our understanding of stroke etiology.

Methods: We analyzed patients enrolled in the NIH FAST-MAG phase 3 trial of field-initiated neuroprotective agents in patients with hyperacute stroke within 2h of onset. Onset times were analyzed in 1h time blocks throughout the 24h day-night cycle. Patient demographic and clinical features, medical history, imaging characteristics, and stroke deficit severity were correlated with onset ...

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 without any ...

Phase 1

Introduction: Prolonged opioid use after lumbar fusion surgery is implicated with increased hospital readmissions, higher postoperative pain scores, and longer return to work time. There are several non-modifiable risk factors for postoperative opioid use including socioeconomic status and gender. The purpose of this study was to determine the effects of opioid-tolerance on PROMs and to determine risk factors for prolonged opioid use after lumbar spine surgery.

Method: Using retrospective cohort analysis, patients who underwent lumbar spinal fusion at TJUH were identified and determined to be either opioid-naïve or opioid-tolerant using the Pennsylvania PDMP. Outcomes included number of opioid tablets consumed ...


Mci: Cpap Treatment Of Osa, Kaitlin Berry, Cindy Cheng, MD, PhD, Karl Doghramji, MD 2020 Thomas Jefferson University

Mci: Cpap Treatment Of Osa, Kaitlin Berry, Cindy Cheng, Md, Phd, Karl Doghramji, Md

Phase 1

Introduction: An estimated 30 percent of adults (20% of men and 10% of women) in the US have sleep apnea. Approximately 60% of patients with Mild Cognitive Impairment (MCI) are also diagnosed with Obstructive Sleep Apnea (OSA). The suggested mechanism of this is damage to the brain due to hypoxia during sleep. Few studies have investigated the effect of Continuous Positive Airway Pressure (CPAP) treatment for OSA, on mild cognitive impairment.

Methods: Patients are screened for eligibility based on specific inclusion and exclusion criteria. Potentially eligible patients who screen positive for MCI using the Telephone Interview for Cognitive Status (TICS ...

Evaluation Of Rotator Cuff Repair With Concomitant Biceps Tenodesis, Matthew Beucherie, Daniel Nemirov, Sommer Hammoud, Md, Meghan Bishop, Md, Brandon Erickson, Md

Phase 1

Introduction: Surgical rotator cuff repair (RCR) has proven to be an effective treatment for rotator cuff tears. Commonly, rotator cuff tears are associated with concomitant biceps pathology, which are often treated by biceps tenodesis (BT). We hypothesize that patient outcomes will be similar in those that have undergone RCR with concomitant BT and isolated RCR.

Methods: This is a retrospective cohort study comparing patients who underwent arthroscopic RCR with arthroscopic or open BT to patients who underwent isolated RCR at a multisurgeon orthopaedic practice during the time period of November 2016 to December 2016. The outcome for comparison is the ...
