A Longer Duration Of Intravenous Antibiotic Treatment For Patients With Early Periprosthetic Joint Infections Is Not Associated With A Lower Failure Rate, Janneke Meijer, Alex Soriano, Wierd Zijlstra, Bas Ten Have, Saad Tarabichi, Paul Jutte, Javad Parvizi, Marjan Wouthuyzen-Bakker

Rothman Institute Papers

BACKGROUND: In recent years, many studies have demonstrated the efficacy of an early switch to oral antibiotics after surgical treatment in orthopedic-related infections. However, large analyses on periprosthetic joint infections (PJIs) are lacking.

MATERIAL AND METHODS: We conducted a retrospective observational multicenter study in patients diagnosed with an early post-operative PJI, defined as one occurringdebridement, antibiotics, and implant retention (DAIR). Patients from Europe and the USA were included. We took advantage of the fact that an early oral antibiotic switch is routine practice in Europe as opposed to a long duration of intravenous (IV) antibiotic treatment in the USA. Failure …

Skeletal And Dental Tissue Mineralization: The Potential Role Of The Endoplasmic Reticulum/Golgi Complex And The Endolysosomal And Autophagic Transport Systems, Irving M. Shapiro, Makarand V. Risbud, Tengteng Tang, William J. Landis

Department of Orthopaedic Surgery Faculty Papers

This paper presents a review of the potential role of the endoplasmic reticulum/Golgi complex and intracellular vesicles in mediating events leading to or associated with vertebrate tissue mineralization. The possible importance of these organelles in this process is suggested by observations that calcium ions accumulate in the tubules and lacunae of the endoplasmic reticulum and Golgi. Similar levels of calcium ions (approaching millimolar) are present in vesicles derived from endosomes, lysosomes and autophagosomes. The cellular level of phosphate ions in these organelles is also high (millimolar). While the source of these ions for mineral formation has not been identified, there …

Ct-Based Visualization Of Aortic Valve Morphology: From 3d Energy-Integrating Ct To 4d Photon Counting Ct, Alison M. Pouch, Jessie N. Dong, Harold I. Litt, Brittany J. Cannon, Melanie Freas, Victor Ferrari, Thomas G. Gleason, Matthew A. Jolley, Natalie Yushkevich, Jessica Nunez, Jilei Hao, Zaiyang Guo, Shir Goldfinger, John Kelly, Joseph E. Bavaria, Nimesh D. Desai

Division of Cardiology Faculty Papers

BACKGROUND: While 4D contrast-enhanced computed tomography (CT) is used to plan cardiovascular interventions such as transcatheter valve replacement, it is not yet routinely used to characterize minimally calcified aortic valves for planning of surgical valve repair. It is widely recognized that aortic valve morphology has implications for the durability of valve repair surgery.

PURPOSE: The objective is to demonstrate the potential of CT image segmentation for elucidating aortic valve morphology prior to surgery and to illustrate a potential benefit of 4D CT and photon counting CT (PCCT) for patient-specific modeling of dysmorphic aortic valves.

MATERIALS AND METHODS: This observational series …

Residual Traditional Risk In Non-Traditional Atherosclerotic Diseases, Federico Biscetti, Giorgia Polito, Maria Margherita Rando, Maria Anna Nicolazzi, Luis H. Eraso, Paul J. Dimuzio, Massimo Massetti, Antonio Gasbarrini, Andrea Flex

Department of Surgery Faculty Papers

Individuals with chronic inflammatory and immune disorders are at an increased risk of atherosclerotic events and premature cardiovascular (CV) disease. Despite extensive literature exploring the relationship between "non-traditional" atherosclerotic conditions and CV risk, many aspects remain unresolved, including the underlying mechanisms promoting the "non-traditional CV risk", the development of an innovative and comprehensive CV risk assessment tool, and recommendations for tailored interventions. This review aims to evaluate the available evidence on key "non-traditional" CV risk-enhancer conditions, with a focus on assessing and managing CV risk factors. We conducted a comprehensive review of 412 original articles, narrative and systematic reviews, and …

Optimizing Long Covid Outcomes: Insights From A Survey Of U.S. Occupational Therapists, Malachy J. Clancy, Phd, Otr/L, Bcpr, Robert Dekerlegand, Pt, Mpt, Phd, Ccs

Department of Occupational Therapy Posters and Presentations

Background & Purpose

• Upwards of 15% of individuals infected with SARS-CoV-2 may develop “Long COVID” with persistent physical, cognitive, and/or mental symptoms potentially amendable to occupational therapy.
• Variability exists in the rehabilitation approach for individuals receiving occupational therapy for this novel condition.
• Clinical practice guidelines (CPGs) and other evidence-based resources exist to help standardized rehabilitation; however, it is unknown if occupational therapists (OTs) are aware of these resources and applying them in the management of individuals with Long COVID.
• We surveyed OTs in the contiguous United States (U.S.) to explore their awareness and application of Long COVID CPGs along with …

Perinuclear Organelle Trauma At The Nexus Of Cardiomyopathy Pathogenesis Arising From Loss Of Function Lmna Mutation, Jason C. Choi

Center for Translational Medicine Faculty Papers

Over the past 25 years, nuclear envelope (NE) perturbations have been reported in various experimental models with mutations in the LMNA gene. Although the hypothesis that NE perturbations from LMNA mutations are a fundamental feature of striated muscle damage has garnered wide acceptance, the molecular sequalae provoked by the NE damage and how they underlie disease pathogenesis such as cardiomyopathy (LMNA cardiomyopathy) remain poorly understood. We recently shed light on one such consequence, by employing a cardiomyocyte-specific Lmna deletion in vivo in the adult heart. We observed extensive NE perturbations prior to cardiac function deterioration with collateral damage in the …

Ghamande, Catherine Ferguson, Loren Mell, Laura Holman, Cara Mathews, David O'Malley, Alexander Olawaiye, Elizabeth Hopp, Charles Leath, Larry Copeland, Robert Mannel, Roisin O'Cearbhaill, Carol Aghajanian, Russell J. Schilder

Department of Medical Oncology Faculty Papers

Combined immune checkpoint blockade (ICB) and chemoradiation (CRT) is approved in patients with locally advanced cervical cancer (LACC) but optimal sequencing of CRT and ICB is unknown. NRG-GY017 (NCT03738228) was a randomized phase I trial of atezolizumab (anti-PD-L1) neoadjuvant and concurrent with CRT (Arm A) vs. concurrent with CRT (Arm B) in patients with high-risk node-positive LACC. The primary endpoint was the fraction of expanded tumor-associated T-cell receptor (TCR) clones in blood at day 21 as a surrogate measure of anti-tumor immune response. Secondary objectives were safety and feasibility, 2-year disease-free survival (DFS), and predictive value of PD-L1 expression. Forty …

Effects Of Sex, Mating Status, And Genetic Background On Circadian Behavior In Drosophila, Oghenerukevwe Akpoghiran, Alexandra K. Strich, Kyunghee Koh

Farber Institute for Neuroscience Faculty Papers

Circadian rhythms play a crucial role in regulating behavior, physiology, and health. Sexual dimorphism, a widespread phenomenon across species, influences circadian behaviors. Additionally, post-mating physiological changes in females are known to modulate various behaviors, yet their effects on circadian rhythms remain underexplored. Here, using Drosophila melanogaster, a powerful model for studying circadian mechanisms, we systematically assessed the impact of sex and mating status on circadian behavior. We measured circadian period length and rhythm strength in virgin and mated males and females, including females mated to males lacking Sex Peptide (SP), a key mediator of post-mating changes. Across four wild-type and …

Two Terrific Nonfiction Scholarly Works, Charles Yeo, Md, Facs

Jefferson Surgical Solutions

As the leaves turn bright with color this autumn, and as we mark the 200th birthday of Thomas Jefferson University, I was reflecting on two books I enjoyed over the last few months, both in the realm of history.

First, Eric H. Cline’s “1177 B.C.: The Year Civilization Collapsed” tells the story, based upon archeologic treasures (some recently discovered) of the Late Bronze Age and the magnificent civilizations from the 15th century B.C. onward (from Mesopotamia, to Greece, to the Hittites, the Levant and Egypt). Cline describes the decline of these grand civilizations due to natural disasters, drought, internal strife …

The Role Of Anthropogenic Influences On A Tropical Lake Ecosystem And Its Surrounding Catchment: A Case Study Of Lake Sentani, Sulung Nomosatryo, Daniel Lipus, Alexander Bartholomäus, Cynthia Henny, Iwan Ridwansyah, Puguh Sujarta, Sizhong Yang, Dirk Wagner, Jens Kallmeyer

College of Life Sciences Faculty Papers

Lake Sentani is a tropical lake in Indonesia, consisting of four interconnected sub-basins of different water depths. While previous work has highlighted the impact of catchment composition on biogeochemical processes in Lake Sentani, little is currently known about the microbiological characteristics across this unique ecosystem. With recent population growth in this historically rural area, the anthropogenic impact on Lake Sentani and hence its microbial life is also increasing. Therefore, we aimed to explore the influence of environmental and anthropogenic factors on the microbial diversity of Lake Sentani. Here, we present a detailed microbiological evaluation of Lake Sentani, analyzing 49 different …

The C-Terminal Phdvc5hch Tandem Domain Of Nsd2 Is A Combinatorial Reader Of Modified H3k4 And Tri-Methylated H3k27 That Regulates Transcription Of Cell Adhesion Genes In Multiple Myeloma, Andrea Berardi, Charlotte Leonie Kaestner, Michela Ghitti, Giacomo Quilici, Paolo Cocomazzi, Jianping Li, Federico Ballabio, Chiara Zucchelli, Stefan Knapp, Jonathan Licht, Giovanna Musco

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Histone methyltransferase NSD2 (MMSET) overexpression in multiple myeloma (MM) patients plays an important role in the development of this disease subtype. Through the expansion of transcriptional activating H3K36me2 and the suppression of repressive H3K27me3 marks, NSD2 activates an aberrant set of genes that contribute to myeloma growth, adhesive and invasive activities. NSD2 transcriptional activity also depends on its non-catalytic domains, which facilitate its recruitment to chromatin through histone binding. In this study, using NMR, ITC and molecular dynamics simulations, we show that the tandem PHD domain of NSD2 (PHDVC5HCHNSD2) is a combinatorial reader of unmodified histone H3K4 and tri-methylated H3K27 …

Pivotal Roles Of Biglycan And Decorin In Regulating Bone Mass, Water Retention, And Bone Toughness, Rui Hua, Yan Han, Qingwen Ni, Roberto J. Fajardo, Renato V. Iozzo, Rafay Ahmed, Jeffry S. Nyman, Xiaodu Wang, Jean X. Jiang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Proteoglycans, key components of non-collagenous proteins in the bone matrix, attract water through their negatively charged glycosaminoglycan chains. Among these proteoglycans, biglycan (Bgn) and decorin (Dcn) are major subtypes, yet their distinct roles in bone remain largely elusive. In this study, we utilized single knockout (KO) mouse models and successfully generated double KO (dKO) models despite challenges with low yield. Bgn deficiency, but not Dcn deficiency, decreased trabecular bone mass, with more pronounced bone loss in dKO mice. Low-field nuclear magnetic resonance measurements showed a marked decrease in bound water among all KO groups, especially in Bgn KO and dKO …

Nls-Binding Deficient Kapβ2 Reduces Neurotoxicity Via Selective Interaction With C9orf72-Als/Ftd Dipeptide Repeats, Kevin Kim, Amandeep Girdhar, Maria Elena Cicardi, V. Kankate, Miyuki Hayashi, Ruoyu Yang, Jenny Carey, Charlotte M Fare, James Shorter, Gino Cingolani, Davide Trotti, Lin Guo

Department of Biochemistry and Molecular Biology Faculty Papers

Arginine-rich dipeptide repeat proteins (R-DPRs) are highly toxic proteins found in patients with C9orf72-linked amyotrophic lateral sclerosis and frontotemporal dementia (C9-ALS/FTD). R-DPRs can cause toxicity by disrupting the natural phase behavior of RNA-binding proteins (RBPs). Mitigating this abnormal phase behavior is, therefore, crucial to reduce R-DPR-induced toxicity. Here, we use FUS as a model RBP to investigate the mechanism of R-DPR-induced aberrant RBP phase transition. We find that this phase transition can be mitigated by Kapβ2. However, as a nuclear import receptor and phase modifier for PY-NLS-containing RBPs, the function of WT Kapβ2 could lead to undesired interaction with its …

Department of Neurosurgery Faculty Papers

Pediatric low-grade gliomas (pLGGs) exhibit heterogeneous prognoses and variable responses to treatment, leading to tumor progression and adverse outcomes in cases where complete resection is unachievable. Early prediction of treatment responsiveness and suitability for immunotherapy has the potential to improve clinical management and outcomes. Here, we present a radiogenomic analysis of pLGGs, integrating MRI and RNA sequencing data. We identify three immunologically distinct clusters, with one group characterized by increased immune activity and poorer prognosis, indicating potential benefit from immunotherapies. We develop a radiomic signature that predicts these immune profiles with over 80% accuracy. Furthermore, our clinicoradiomic model predicts progression-free …

The Process And Significance Of Convening A Community Advisory Board With Individuals With Severe Mental Illness, Jacelyn Biondo, Nia Johnson

Department of Medicine Faculty Papers

Individuals with lived experience of being diagnosed with severe mental illness and/or substance use disorders have deep and profound knowledge regarding the culture and needs of their community. Historically, these and other vulnerable populations have been excluded from care access, treatment insights, research development and participation, and often society in general. In this paper, we share our experience of convening a community advisory board with vulnerable populations and highlight the expertise these community members provide. We outline our processes of convening the community advisory board, engaging in collaborative meetings, revising the research protocol, and exploring future research needs. Using meeting …

An Evaluation Of The Decline In Primary Care Physician Visits, 2010 To 2021, Anuradha Jetty, Marie Ezran, Alison Huffstetler, Yalda Jabbarpour

Department of Family & Community Medicine Faculty Papers

INTRODUCTION: Primary care is the backbone of the United States healthcare system, yet it continues to be underfunded and inaccessible to many. Previous studies explored primary care visit patterns until 2016, leaving gaps in our understanding of how recent factors like state Medicaid expansions, the Coronavirus Disease 2019 (COVID-19) pandemic, and population growth have influenced these patterns. Hence, the objective of the current study was to analyze the trends in primary care visits provided by outpatient clinicians over time and by visit type and contextualize study findings within the changing healthcare landscape.

METHODS: The Medical Expenditure Panel Survey data (2010-2021) …

Tryptophan Kynurenine Pathway-Based Imaging Agents For Brain Disorders And Oncology-From Bench To Bedside, Erik Stauff, Wenqi Xu, Heidi H. Kecskemethy, Sigrid A. Langhans, Vinay V. R. Kandula, Lauren W. Averill, Xuyi Yue

Jefferson Hospital Staff Papers and Presentations

Tryptophan (Trp)-based radiotracers have excellent potential for imaging many different types of brain pathology because of their involvement with both the serotonergic and kynurenine (KYN) pathways. However, radiotracers specific to the kynurenine metabolism pathway are limited. In addition, historically Trp-based radiopharmaceuticals were synthesized with the short-lived isotope carbon-11. A newer generation of Trp-based imaging agents using the longer half-lived and commercially available isotopes, such as fluorine-18 and iodine-124, are being developed. The newly developed amino acid-based tracers have been demonstrated to have favorable radiochemical and imaging characteristics in pre-clinical studies. However, many barriers still exist in the clinical translation of …
