Systems View Of Coronavirus, Sung Won Paek, Larry M. Starr

School of Continuing and Professional Studies Coronavirus Papers

No one envisioned the kinds of problems that emerged from the novel coronavirus nor had anyone considered its interactive scope. Now is the time to begin to redesign our processes and systems so that when confronted again we can cope and navigate better. Everyone needs to be a partner in these redesigns and each of the health, social, educational, and other systems must be integrated because it is their interconnections that coproduce and give meaning to our lives.

Health Screenings Administered During The Domestic Medical Examination Of Refugees And Other Eligible Immigrants In Nine Us States, 2014-2016: A Cross-Sectional Analysis., Clelia Pezzi, Deborah Lee, Gayathri S. Kumar, Breanna Kawasaki, Lori Kennedy, Jenny Aguirre, Melissa Titus, Rebecca Ford, Blain Mamo, Kailey Urban, Stephen Hughes, Colleen Payton, Kevin Scott, Jessica Montour, Emily S. Jentes

Department of Family & Community Medicine Faculty Papers

BACKGROUND: Refugees and other select visa holders are recommended to receive a domestic medical examination within 90 days after arrival to the United States. Limited data have been published on the coverage of screenings offered during this examination across multiple resettlement states, preventing evaluation of this voluntary program's potential impact on postarrival refugee health. This analysis sought to calculate and compare screening proportions among refugees and other eligible populations to assess the domestic medical examination's impact on screening coverage resulting from this examination.

METHODS AND FINDINGS: We conducted a cross-sectional analysis to summarize and compare domestic medical examination data from …

Approaches To Overcome Flow Cytometry Limitations In The Analysis Of Cells From Veterinary Relevant Species, Julia Hunka, John T. Riley, Gudrun F. Debes

Department of Microbiology and Immunology Faculty Papers

BACKGROUND: Flow cytometry is a powerful tool for the multiparameter analysis of leukocyte subsets on the single cell level. Recent advances have greatly increased the number of fluorochrome-labeled antibodies in flow cytometry. In particular, an increase in available fluorochromes with distinct excitation and emission spectra combined with novel multicolor flow cytometers with several lasers have enhanced the generation of multidimensional expression data for leukocytes and other cell types. However, these advances have mainly benefited the analysis of human or mouse cell samples given the lack of reagents for most animal species. The flow cytometric analysis of important veterinary, agricultural, wildlife, …

Proximal Tibial Replacement In Revision Knee Arthroplasty For Non-Oncologic Indications., Brianna Fram, Eric B. Smith, Gregory K. Deirmengian, John A. Abraham, John Strony, Michael B. Cross, Danielle Y. Ponzio

Rothman Institute Papers

Proximal tibial metaphyseal bone loss compromises the alignment and fixation of components during revision total knee arthroplasty. In massive, segmental defects with loss of collateral ligamentous support and lack of bone to support the use of prosthetic augments or metaphyseal cones or sleeves, a hinged proximal tibial replacement or a so-called "megaprosthesis" should be available. While proximal tibial replacement is the reconstructive method of choice in the setting of bone tumor resection, applications in non-oncologic joint arthroplasty are rare and may offer an opportunity for limb salvage in dire clinical scenarios with massive proximal tibial bone loss. This report reviews …

Our Wicked Problem, John Pourdehnad, Larry M. Starr, Venard Scott Koerwer, Harry Mccloskey

School of Continuing and Professional Studies Coronavirus Papers

The Coronavirus is more than a health problem. It is a “wicked” problem disrupting work, education, travel, politics, financial indicators, and more. This label came about in 1973 to help describe a special class of situations that are volatile, uncertain and ambiguous, often difficult to recognize, and difficult or impossible to solve because of incomplete, contradictory, and changing requirements. There is no clear problem definition due to interdependencies so the problem cannot be fully understood until after the solution comes about.

Our Invisible Enemy, Larry M. Starr, Darshi Mody

School of Continuing and Professional Studies Coronavirus Papers

The novel coronavirus is invisible to the eye because it is microscopic measuring 80-160 nanometers in size; a nanometer is one billionth of a meter.

While we cannot see it in the air or on a surface, millions of us have seen the virus in full color when we discuss it on the local and national TV news, in articles and stories online, and in print media. This is because the virus is routinely pictured and used to attract us to the information being presented. The paradox is that millions of people can now recognize this invisible enemy.

Repeatedly presenting …

Disruptive Effects Of The Coronavirus – Errors Of Commission And Of Omission?, John Pourdehnad, Larry M. Starr, Venard Scott Koerwer, Harry Mccloskey

School of Continuing and Professional Studies Coronavirus Papers

It is increasingly evident that the coronavirus disease, COVID-19, is more than a health problem; it is and will continue to adversely affect work and workplaces, education, families and social engagements, political and environmental dimensions, and financial indicators. Apart from its health ramifications, the crisis is revealing serious challenges in the global supply chain. Those difficulties are, at least in part, consequences of unwise, short-sighted business decisions made over the course of decades to outsource and downsize.

Pandemic Lockdown Must Fail: Save Lives Without Crippling The Economy, Larry Hirschhorn, Phd

School of Continuing and Professional Studies Coronavirus Papers

In the following working paper, I want to make a plea for what I am calling a “reverse quarantine”—quarantining people who are over 65 (who number 52 million), before they get sick. We need to complement this policy with federally funded and locally organized efforts to support seniors in place, drawing on the wellsprings of American pragmatism, the capacity to respond in emergencies, American volunteerism, and neighbor-to-neighbor assistance. We can’t turn quarantine into imprisonment. We must work as hard as we can to create a psychological sense of community at a moment when, paradoxically, social distancing is driving us apart. …

Health Of Special Immigrant Visa Holders From Iraq And Afghanistan After Arrival Into The United States Using Domestic Medical Examination Data, 2014-2016: A Cross-Sectional Analysis., Gayathri S Kumar, Clelia Pezzi, Simone Wien, Blain Mamo, Kevin Scott, Colleen Payton, Kailey Urban, Stephen Hughes, Lori Kennedy, Nuny Cabanting, Jessica Montour, Melissa Titus, Jenny Aguirre, Breanna Kawasaki, Rebecca Ford, Emily S Jentes

Department of Family & Community Medicine Faculty Papers

BACKGROUND: Since 2008, the United States has issued between 2,000 and 19,000 Special Immigrant Visas (SIV) annually, with the majority issued to applicants from Iraq and Afghanistan. SIV holders (SIVH) are applicants who were employed by, or on behalf of, the US government or the US military. There is limited information about health conditions in SIV populations to help guide US clinicians caring for SIVH. Thus, we sought to describe health characteristics of recently arrived SIVH from Iraq and Afghanistan who were seen for domestic medical examinations.

METHODS AND FINDINGS: This cross-sectional analysis included data from Iraqi and Afghan SIVH …

Effects Of Co-Infection On The Clinical Outcomes Of Clostridium Difficile Infection, Muhammad Shafiq, Hani Alturkmani, Yousaf Zafar, Vishal Mittal, Hafsa Lodhi, Waqas Ullah, Joseph Brewer

Abington Jefferson Health Papers

Background: Clostridium difficile (C. difficile) is a spore-forming, Gram-positive rod that is known to be associated with antibiotic use. It is one of the leading causes of nosocomial diarrhea in the industrialized world and therefore warrants further study of its nature. It isn't clear if co-infection by other organisms can affect the outcome of C. difficile infection (CDI).

Methods: A single center retrospective study was done and it used inclusion criteria of 18 years of age and being tested positive for CDI on FilmArray® multiplex gastro-intestinal (GI) panel. Exclusion criteria were a GI panel performed on an outpatient …

Dna Dependent Protein Kinase (Dna-Pk) Enhances Hiv Transcription By Promoting Rna Polymerase Ii Activity And Recruitment Of Transcription Machinery At Hiv Ltr., Sonia Zicari, Adhikarimayum Lakhikumar Sharma, Geetaram Sahu, Larisa Dubrovsky, Lin Sun, Han Yue, Tejaswi Jada, Alex Ochem, Gary Simon, Michael Bukrinsky, Mudit Tyagi

Center for Translational Medicine Faculty Papers

Despite reductions in mortality from the use of highly active antiretroviral therapy (HAART), the presence of latent or transcriptionally silent proviruses prevents HIV cure/eradication. We have previously reported that DNA-dependent protein kinase (DNA-PK) facilitates HIV transcription by interacting with the RNA polymerase II (RNAP II) complex recruited at HIV LTR. In this study, using different cell lines and peripheral blood mononuclear cells (PBMCs) of HIV-infected patients, we found that DNA-PK stimulates HIV transcription at several stages, including initiation, pause-release and elongation. We are reporting for the first time that DNA-PK increases phosphorylation of RNAP II C-terminal domain (CTD) at serine …

Vancomycin In Peritoneal Dialysis: Clinical Pharmacology Considerations In Therapy., Edwin Lam, Yi Ting Kayla Lien, Walter K. Kraft, Beth Piraino, Valvanera Vozmediano, Stephan Schmidt, Jingjing Zhang

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Intraperitoneal vancomycin is the first-line therapy in the management of peritoneal dialysis (PD)-related peritonitis. However, due to the paucity of data, vancomycin dosing for peritonitis in patients on automated peritoneal dialysis (APD) is empiric and based on clinical experience rather than evidence. Studies in continuous ambulatory peritoneal dialysis (CAPD) patients have been used to provide guidelines for dosing and are often extrapolated for APD use, but it is unclear whether this is appropriate. This review summarizes the available pharmacokinetic data used to inform optimal dosing in patients on CAPD or APD. The determinants of vancomycin disposition and pharmacodynamic effects are …

Accepting Higher Morbidity In Exchange For Sacrificing Fewer Animals In Studies Developing Novel Infection-Control Strategies., Henk J. Busscher, Willem Woudstra, Theo G. Van Kooten, Paul Jutte, Linqi Shi, Jianfeng Liu, Wouter L.J. Hinrichs, Hendrik W. Frijlink, Rui Shi, Jian Liu, Javad Parvizi, Stephen Kates, Vincent M. Rotello, Thomas P. Schaer, Dustin Williams, David W. Grainger, Henny C. Van Der Mei

Rothman Institute Papers

Preventing bacterial infections from becoming the leading cause of death by the year 2050 requires the development of novel, infection-control strategies, building heavily on biomaterials science, including nanotechnology. Pre-clinical (animal) studies are indispensable for this development. Often, animal infection outcomes bear little relation to human clinical outcome. Here, we review conclusions from pathogen-inoculum dose-finding pilot studies for evaluation of novel infection-control strategies in murine models. Pathogen-inoculum doses are generally preferred that produce the largest differences in quantitative infection outcome parameters between a control and an experimental group, without death or termination of animals due to having reached an inhumane end-point …

Acoustic Parameters For Optimal Ultrasound-Triggered Release From Novel Spinal Hardware Devices., Lauren J. Delaney, Cemile Basgul, Daniel W Macdonald, Keith Fitzgerald, Noreen J. Hickok, Steven M Kurtz, Flemming Forsberg

Department of Radiology Faculty Papers

Post-operative infection is a catastrophic complication of spinal fusion surgery, with rates as high as 10%, and existing preventative measures (i.e., peri-operative antibiotics) are only partially successful. To combat this clinical problem, we have designed a drug delivery system around polyether ether ketone clips to be used for prophylactic post-surgical release of antibiotics upon application of ultrasound. The overall hypothesis is that antimicrobial release from this system will aggressively combat post-surgical bacterial survival. This study investigated a set of acoustic parameters optimized for in vitro ultrasound-triggered coating rupture and subsequent release of encapsulated prophylactic antibiotics. We determined that a transducer …

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

Phase 1

Background: Catheter associated urinary tract infections (CAUTI) are a major source of patient morbidity and mortality in healthcare settings and have a significant financial impact on the healthcare system. Many hospitals have clinical protocols in place to continually reassess the necessity of indwelling foley catheters and remove them if their use is no longer warranted. However, it is still common for indwelling foley catheters to be overlooked and remain in place, even after meeting criteria for removal. A design project was conducted that sought to improve adherence to clinical protocols, and reduce frequency of CAUTIs, by creating a color-changing device …

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 …

An Investigation Of Infectious Etiologies Of Sporadic Inclusion Body Myositis, Tyler Kennedy, Michele Meltzer, Md

Phase 1

Introduction: Sporadic inclusion body myositis (sIBM) is a rare, debilitating disease that can significantly lower one’s quality of life. Unfortunately, there are no current effective treatments, as the underlying causes are still unknown. We hypothesize that preceding infections do not cause sporadic inclusion body myositis.

Methods: The study investigated patients with a diagnosis of inclusion body myositis, with a concurrent or previously documented infection. Men represented a larger proportion of the population as they have an increased preponderance of those affected. The primary objective was to discern which infection, if any, could induce the inflammatory and degenerative changes in muscle …

Prevalence Of Asymptomatic Gonorrhea And Chlamydia Infections Among Ryan White Hiv Population Visiting A Center City Hiv Clinic, Sarah Stuccio, Rakhshanda Akram, Lisa A. Spacek

Phase 1

Introduction: Sexually transmitted infections (STIs) are a major public health problem. Two factors make their diagnosis challenging: frequent asymptomatic presentation and lack of screening, especially at extragenital sites. Additionally, STIs including gonorrhea (GC) and chlamydia (CT) have been shown to increase the risk of sexual HIV transmission. Information about the prevalence, as well as predictors of test positivity, of GC and CT infections can stress the importance of universal screening.

Methods: We carried out a retrospective analysis of the STI screening of patients who attended the Ryan White HIV clinic at Jefferson between 2016 and 2018. The primary …

Effect Of Contrast-Enhanced Echocardiograms On The Prognosis Of Infective Endocarditis, D. Arias, E. Halpern, F. Forsberg, J. R. Eisenbrey

Phase 1

Objective - Infective endocarditis (IE) is an infectious disease of the cardiac valves where bacteria colonize the valves; typically, via the formation of vegetations. Recent research has shown that the microbubbles in a contrast-enhanced ultrasound (CEUS) examination can move and dislodge bacterial vegetations in vitro. This study investigated whether CEUS resulted in faster resolution of IE in vivo by dislodging the vegetations.

Methods - This IRB approved retrospective study reviewed 36 patients who were diagnosed with IE via echocardiography. Data was sourced from patients within the Jefferson University Hospital’s Cardiology EMR system by searching for contrast and vegetation from …
