Hepatitis C Virus Detection And Management After Implementation Of Universal Screening In Pregnancy, Sarah Boudova, Danielle Tholey, Elizabeth Ferries-Rowe

Division of Gastroenterology and Hepatology Faculty Papers

BACKGROUND: Accurately identifying cases of hepatitis C virus has important medical and public health consequences. In the setting of rising hepatitis C virus prevalence and highly effective treatment with direct-acting antivirals, the Society for Maternal-Fetal Medicine guidelines recently changed to recommend universal screening for hepatitis C virus during pregnancy. However, there is little data on the influence of this policy change on case identification and management. OBJECTIVE: We aimed to examine the influence of universal hepatitis C virus screening on our patient population. Our primary objective was to determine if there was a difference in the detected hepatitis C virus …

Department of Microbiology and Immunology Faculty Papers

The mRNA-LNP vaccine has received much attention during the COVID-19 pandemic since it served as the basis of the most widely used SARS-CoV-2 vaccines in Western countries. Based on early clinical trial data, these vaccines were deemed safe and effective for all demographics. However, the latest data raise serious concerns about the safety and effectiveness of these vaccines. Here, we review some of the safety and efficacy concerns identified to date. We also discuss the potential mechanism of observed adverse events related to the use of these vaccines and whether they can be mitigated by alterations of this vaccine mechanism …

A multinational outbreak of nosocomial fusarium meningitis occurred among immunocompetent patients who had undergone surgery with epidural anesthesia in Mexico. The pathogen involved had a high predilection for the brain stem and vertebrobasilar arterial system and was associated with high mortality from vessel injury. Effective treatment options remain limited; in vitro susceptibility testing of the organism suggested that it is resistant to all currently approved antifungal medications in the United States. To highlight the severe complications associated with fusarium infection acquired in this manner, we report data, clinical courses, and outcomes from 13 patients in the outbreak who presented with …

Eosinophils Restrain Humoral Alloimmunity After Lung Transplantation, Zhongcheng Mei, Yuriko Terada, Yuhei Yokoyama, Andrew E. Gelman, Daniel Kreisel, Et Al.

2020-Current year OA Pubs

While the function of many leukocytes in transplant biology has been well defined, the role of eosinophils is controversial and remains poorly explored. Conflicting data exist regarding eosinophils' role in alloimmunity. Due to their prevalence in the lung, and their defined role in other pulmonary pathologies such as asthma, we set out to explore the role of eosinophils in the long-term maintenance of the lung allograft. We noted that depletion of eosinophils results in the generation of donor-specific antibodies. Eosinophil depletion increased memory B cell, plasma cell, and antibody-secreting cell differentiation and resulted in de novo generation of follicular germinal …

Immunoglobulin (IG) replacement products are used routinely in patients with immune deficiency and other immune dysregulation disorders who have poor responses to vaccination and require passive immunity conferred by commercial antibody products. The binding, neutralizing, and protective activity of intravenously administered IG against SARS-CoV-2 emerging variants remains unknown. Here, we tested 198 different IG products manufactured from December 2019 to August 2022. We show that prepandemic IG had no appreciable cross-reactivity or neutralizing activity against SARS-CoV-2. Anti-spike antibody titers and neutralizing activity against SARS-CoV-2 WA1/2020 D614G increased gradually after the pandemic started and reached levels comparable to vaccinated healthy donors …

ABSTRACT: A significant increase of hospital-acquired bacterial infections during the COVID-19 pandemic has become an urgent medical problem. Clostridioides difficile is an urgent antibiotic-resistant bacterial pathogen and a leading causative agent of nosocomial infections. The increasing recurrence of C. difficile infection and antibi­otic resistance in C. difficile has led to an unmet need for the discovery of new com­pounds distinctly different from present antimicrobials, while antimicrobial peptides as promising alternatives to conventional antibiotics have attracted growing interest recently. Protein synthesis is an essential metabolic process in all bacteria and a validated antibiotic target. Initiation factor 1 from C. difficile (Cd-IF1) …

Sexual Orientation And Gender Identity Measures And Viral Suppression For People Living With Hiv: A Protocol For A Population-Based Cohort Study, Xueying Yang, Bankole Olatosi Ph.D., Sharon Weissman, Xiaoming Li Ph.D., Jiajia Zhang Ph.D.

Faculty Publications

Introduction The measure of sexual orientation and gender identity (SOGI) data in electronic health records (EHR) has been critical for addressing health disparities and inequalities, especially for HIV care. Given that gender and sexual minorities (eg, transgender, men who have sex with men and intersex) are key groups in people living with HIV (PLWH), SOGI data can facilitate a more accurate understanding about the HIV outcomes (eg, viral suppression) among this key group and then lead to tailored therapeutic services. The two-step SOGI collection method as an emerging gender measurement can be used to measure SOGI status in medical settings. …

Longitudinal Attacks Against Iterative Data Collection With Local Differential Privacy, Mehmet Emre Gürsoy Feb 2024

Longitudinal Attacks Against Iterative Data Collection With Local Differential Privacy, Mehmet Emre Gürsoy

Turkish Journal of Electrical Engineering and Computer Sciences

Local differential privacy (LDP) has recently emerged as an accepted standard for privacy-preserving collection of users’ data from smartphones and IoT devices. In many practical scenarios, users’ data needs to be collected repeatedly across multiple iterations. In such cases, although each collection satisfies LDP individually by itself, a longitudinal collection of multiple responses from the same user degrades that user’s privacy. To demonstrate this claim, in this paper, we propose longitudinal attacks against iterative data collection with LDP. We formulate a general Bayesian adversary model, and then individually show the application of this adversary model on six popular LDP protocols: …

Multiple myeloma (MM) is a rarely curable malignancy of plasma cells. MM expresses B cell maturation antigen (BCMA). We developed a fully human anti-BCMA chimeric antigen receptor (CAR) with a heavy-chain-only antigen-recognition domain, a 4-1BB domain, and a CD3ζ domain. The CAR was designated FHVH33-CD8BBZ. We conducted the first-in-humans clinical trial of T cells expressing FHVH33-CD8BBZ (FHVH-T). Twenty-five patients with relapsed MM were treated. The stringent complete response rate (sCR) was 52%. Median progression-free survival (PFS) was 78 weeks. Of 24 evaluable patients, 6 (25%) had a maximum cytokine-release syndrome (CRS) grade of 3; no patients had CRS of greater …

How The Physical, Social, And Psychological Environment Impacts Border Security, John J. Smietana Jr.

Doctoral Dissertations and Projects

Crime prevention through environmental design (CPTED) is a theory of crime control that posits that crime can be mitigated by shaping the physical, psychological, and social environment to prevent the meeting of perpetrators and victims. Over several decades, the United States applied the principles of CPTED to the United States-Mexico border in San Diego to secure the international border. Despite the sovereign right to secure the international border, border security became a divisive and emotionally charged topic in the United States. Studies on the effectiveness of border security were qualitative and humanitarian, describing how border security negatively impacted certain groups …

Tumor-Associated Antigen Targets For Novel Immune-Based Strategies In Prostate Cancer, Amman Bhasin, Patrick Mille, Aditya Eturi, Andrew Iskander, William Tester, Kevin Zarrabi

Kimmel Cancer Center Faculty Papers

Prostate cancer remains the most common malignancy among men in the United States. Advancements in androgen receptor signaling blockade have led to landmark approvals for its use in patients with locally advanced and metastatic disease. However, additional novel therapeutic strategies for both hormone-sensitive and castration-resistant diseases remain ongoing areas of study. Thus, we turn to the growth of immuno-oncology, which has led to improved treatment outcomes for a variety of hematologic and solid tumor malignancies. Prostate cancers have shown only modest results with immune checkpoint inhibition in published trials, and innovative strategies are now looking into enhancing cytotoxic T-cell activity …

The NOD-like receptor (NLR) family pyrin domain containing 6 (NLRP6) serves as a sensor for microbial dsRNA or lipoteichoic acid (LTA) in intestinal epithelial cells (IECs), and initiating multiple pathways including inflammasome pathway and type I interferon (IFN) pathway, or regulating nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) pathways. NLRP6 can exert its function in both inflammasome-dependent and inflammasome-independent manners. However, there is no tool to distinguish the contribution of individual NLRP6-mediated pathway to the physiology and pathology in vivo. Here, we validated that Arg39 and Trp50 residues in the pyrin domain (PYD) of murine NLRP6 are required for …

Introduction The aetiology of bacterial vaginosis (BV), a biofilm-associated vaginal infection, remains unknown. Epidemiologic data suggest that it is sexually transmitted. BV is characterised by loss of lactic acid-producing lactobacilli and an increase in facultative and strict anaerobic bacteria. Gardnerella spp are present in 95%–100% of cases; Gardnerella vaginalis has been found to be more virulent than other BV-associated bacteria (BVAB) in vitro. However, G. vaginalis is found in women with normal vaginal microbiota and colonisation is not sufficient for BV development. We hypothesise that Gardnerella spp initiate BV biofilm formation, but incident BV (iBV) requires incorporation of other key …
