Clinical characteristics were also obtained, including race, sex, age, tobacco and alcohol use, tumor staging, and treatment modality. A feature selection algorithm was used to eliminate the most redundant features, followed by a selection of the best subset of the Logistic regression model (LRM). The …

Topographical And Cell Type-Specific Connectivity Of Rostral And Caudal Forelimb Corticospinal Neuron Populations, Lina Marcela Carmona, Eric D Thomas, Kimberly Smith, Bosiljka Tasic, Rui M Costa, Anders Nelson

Faculty, Staff and Student Publications

Corticospinal neurons (CSNs) synapse directly on spinal neurons, a diverse assortment of cells with unique structural and functional properties necessary for body movements. CSNs modulating forelimb behavior fractionate into caudal forelimb area (CFA) and rostral forelimb area (RFA) motor cortical populations. Despite their prominence, the full diversity of spinal neurons targeted by CFA and RFA CSNs is uncharted. Here, we use anatomical and RNA sequencing methods to show that CSNs synapse onto a remarkably selective group of spinal cell types, favoring inhibitory populations that regulate motoneuron activity and gate sensory feedback. CFA and RFA CSNs target similar spinal neuron types, …

Associations Between Stress, Health Behaviors, And Quality Of Life In Young Couples During The Transition To Survivorship: Protocol For A Measurement Burst Study, Dalnim Cho, Michael Roth, Susan K Peterson, Kristofer Jennings, Seokhun Kim, Shiao-Pei Weathers, Sairah Ahmed, J Andrew Livingston, Carlos Barcenas, Y Nancy You, Kathrin Milbury

Faculty, Staff and Student Publications

BACKGROUND: Cancer is a life-threatening, stressful event, particularly for young adults due to delays and disruptions in their developmental transitions. Cancer treatment can also cause adverse long-term effects, chronic conditions, psychological issues, and decreased quality of life (QoL) among young adults. Despite numerous health benefits of health behaviors (eg, physical activity, healthy eating, no smoking, no alcohol use, and quality sleep), young adult cancer survivors report poor health behavior profiles. Determining the associations of stress (either cancer-specific or day-to-day stress), health behaviors, and QoL as young adult survivors transition to survivorship is key to understanding and enhancing these survivors' health. …

Pediatric hematopoietic cell transplant (HCT) recipients exhibit poor serologic responses to influenza vaccination early after transplant. To facilitate the optimization of influenza vaccination timing, we sought to identify B- and T-cell subpopulations associated with influenza vaccine immunogenicity in this population. We used mass cytometry to phenotype peripheral blood mononuclear cells collected from pediatric HCT recipients enrolled in a multicenter influenza vaccine trial comparing high- and standard-dose formulations over 3 influenza seasons (2016-2019). We fit linear regression models to estimate relationships between immune cell subpopulation numbers before vaccination and prevaccination to postvaccination geometric mean fold rises in antigen-specific (A/H3N2, A/H1N1, and …

Endocarditis: A Review Of Recent Literature, Scott Dale, Zaid Tayyem, Steven Maceyko

Jefferson Hospital Staff Papers and Presentations

Purpose of Review

Endocarditis remains a challenging diagnosis, with significant implications for early identification and initiation of therapy. In this review, we examine the evolution in the epidemiology and presentation of infectious endocarditis (IE), the role of new diagnostic tools, and the approach to therapy.

Recent Findings

Staphylococcus and Streptococcus species remain the most common causative organisms, but the prevalence of IE caused by enterococcus and non-HACEK organisms is increasing. While newer antibiotics such as dalbavancin have shown promise, treatment must still be tailored on an individual basis. Evidence suggests that antibiotic prophylaxis to prevent IE be limited to high-risk …

Department of Medical Oncology Faculty Papers

Urothelial carcinoma (UC) is the fourth most prevalent cancer amongst males worldwide. While patients with non-muscle-invasive disease have a favorable prognosis, 25% of UC patients present with locally advanced disease which is associated with a 10-15% 5-year survival rate and poor overall prognosis. Muscle-invasive bladder cancer (MIBC) is associated with about 50% 5 year survival when treated by radical cystectomy or trimodality therapy; stage IV disease is associated with 10-15% 5 year survival. Current therapeutic modalities for MIBC include neoadjuvant chemotherapy, surgery and/or chemoradiation, although patients with relapsed or refractory disease have a poor prognosis. However, the rapid success of …

Faculty, Staff and Student Publications

Brain-like energy-efficient computing has remained elusive for neuromorphic (NM) circuits and hardware platform implementations despite decades of research. In this work we reveal the opportunity to significantly improve the energy efficiency of digital neuromorphic hardware by introducing NM circuits employing two-dimensional (2D) transition metal dichalcogenide (TMD) layered channel material-based tunnel-field-effect transistors (TFETs). Our novel leaky-integrate-fire (LIF) based digital NM circuit along with its Hebbian learning circuitry operates at a wide range of supply voltages, frequencies, and activity factors, enabling two orders of magnitude higher energy-efficient computing that is difficult to achieve with conventional material and/or device platforms, specifically the silicon-based …

Comprehensive Guidance For The Prevention Of Periprosthetic Joint Infection After Total Joint Arthroplasty And Pitfalls In The Prevention, Javad Parvizi, Yonghan Cha, Emanuele Chisari, Kangbaek Kim, Kyung-Hoi Koo

Rothman Institute Papers

Total joint arthroplasty (TJA) is a surgical procedure, in which parts of damaged joints are removed and replaced with a prosthesis. The main indication of TJA is osteoarthritis, and the volume of TJA is rising annually along with the increase of aged population. Hip and knee are the most common joints, in which TJAs are performed. The TJA prosthesis is composed of metal, plastic, or ceramic device. Even though TJA is the most successful treatment for end-stage osteoarthritis, it is associated with various complications, and periprosthetic joint infection (PJI) is the most serious complication after TJA. With the increasing volume …

An Estrogen Receptor Α-Derived Peptide Improves Glucose Homeostasis During Obesity, Wanbao Yang, Wen Jiang, Wang Liao, Hui Yan, Weiqi Ai, Quan Pan, Wesley A Brashear, Yong Xu, Ling He, Shaodong Guo

Faculty, Staff and Students Publications

Estrogen receptor α (ERα) plays a crucial role in regulating glucose and energy homeostasis during type 2 diabetes mellitus (T2DM). However, the underlying mechanisms remain incompletely understood. Here we find a ligand-independent effect of ERα on the regulation of glucose homeostasis. Deficiency of ERα in the liver impairs glucose homeostasis in male, female, and ovariectomized (OVX) female mice. Mechanistic studies reveal that ERα promotes hepatic insulin sensitivity by suppressing ubiquitination-induced IRS1 degradation. The ERα 1-280 domain mediates the ligand-independent effect of ERα on insulin sensitivity. Furthermore, we identify a peptide based on ERα 1-280 domain and find that ERα-derived peptide …

School of Medicine Faculty Publications

Objectives: Sepsis is one of the most common, costly, and misdiagnosed conditions in U.S. emergency departments (EDs). ED providers often treat on nonspecific signs, subjective suspicion, or presumption of infection, resulting in over- and undertreatment. An increased understanding of host response has opened a new direction for sepsis diagnostics. The IntelliSep test is a U.S. Food and Drug Administration–cleared cellular host response diagnostic that could help distinguish sepsis in ED settings. Our objective was to evaluate the potential of the cellular host response test to expedite appropriate care for patients who present with signs of infection. Methods: We performed a …

Oral squamous cell carcinoma (OSCC) presents significant treatment challenges due to its poor survival and intense pain at the primary cancer site. Cancer pain is debilitating, contributes to diminished quality of life, and causes opioid tolerance. The stimulator of interferon genes (STING) agonism has been investigated as an anti-cancer strategy. We have developed STINGel, an extended-release formulation that prolongs the availability of STING agonists, which has demonstrated an enhanced anti-tumor effect in OSCC compared to STING agonist injection. This study investigates the impact of intra-tumoral STINGel on OSCC-induced pain using two separate OSCC models and nociceptive behavioral assays. Intra-tumoral STINGel …

Adding Ofirmev: The Effectiveness Of Multimodal Treatment, Kimberly R. Bilal-Williams

This project is on enhancing pain management in total knee arthroplasty (TKA) clients via the intravenous (IV) administration of acetaminophen (Ofirmev) by multimodal regimen. The patient, intervention, comparison, outcome, and time (PICOT) question shaping this initiative looks at frequency and intensity of patients’ pain scores as well as practical outcome measures such as healing and physical therapy during the recovery period ending with discharge. After a thorough literature synopsis, it is evident that multimodal pain management strategies including IV acetaminophen provide a better prospectus in comparison to the ones that solely employ opioids. Research repeatedly demonstrates the use of IV …

Reducing Central Line-Associated Bloodstream Infections (Clabsi) With Chlorhexidine-Impregnated Dressings, Sara Garcia

MSN Capstone Projects

Mitigating and eradicating central line-associated bloodstream infections (CLABSI) is a vital patient safety priority. These healthcare-associated infections lead to patient fatalities and incur costly, preventable expenses. Therefore, it is imperative to assess central venous catheter (CVC) maintenance protocols to mitigate the likelihood of infection. Federal guidelines advocate using chlorhexidine (CHG) dressings to lower this risk (Centers for Disease Control and Prevention, 2017). A comprehensive central line maintenance bundle includes incorporating a CHG dressing as a critical measure in reducing the risk of CLABSI (Buetti et al., 2022). Consequently, the escalating infection rates underscore the necessity for implementing CHG dressings (Buetti …

The curative treatment of multiple solid tumors, including head and neck squamous cell carcinoma (HNSCC), utilizes radiation. The outcomes for HPV/p16-negative HNSCC are significantly worse than HPV/p16-positive tumors, with increased radiation resistance leading to worse locoregional recurrence (LRR) and ultimately death. This study analyzed the relationship between immune function and outcomes following radiation in HPV/p16-negative tumors to identify mechanisms of radiation resistance and prognostic immune biomarkers. A discovery cohort of 94 patients with HNSCC treated uniformly with surgery and adjuvant radiation and a validation cohort of 97 similarly treated patients were utilized. Tumor immune infiltrates were derived from RNAseq gene …
