Seasonal coronaviruses (HCoVs) are known to contribute to cross-reactive antibody (Ab) responses against SARS-CoV-2. While these responses are predictable due to the high homology between SARS-CoV-2 and other CoVs, the impact of these responses on susceptibility to SARS-CoV-2 infection in cancer patients is unclear. To investigate the influence of prior HCoV infection on anti-SARS-CoV-2 Ab responses among COVID-19 asymptomatic individuals with cancer and controls without cancers, we utilized the VirScan technology in which phage immunoprecipitation and sequencing (PhIP-seq) of longitudinal plasma samples was performed to investigate high-resolution (i.e., epitope level) humoral CoV responses. Despite testing positive for anti-SARS-CoV-2 Ab in …

IMPORTANCE: West Nile virus (WNV) is the leading cause of human arboviral disease in the US, peaking during summer. The incidence of WNV, including its neuroinvasive form (NWNV), is increasing, largely due to the expanding distribution of its vector, the Culex mosquito, and climatic changes causing heavy monsoon rains. However, the distinct characteristics and outcomes of NWNV in individuals who are immunosuppressed (IS) and individuals who are not IS remain underexplored.

OBJECTIVE: To describe and compare clinical and radiographic features, treatment responses, and outcomes of NWNV infection in individuals who are IS and those who are not IS.

Adipose Tissue Dysfunction And Energy Balance Paradigms In People Living With Hiv, Claudia E Ramirez Bustamante, Neeti Agarwal, Aaron R Cox, Sean M Hartig, Jordan E Lake, Ashok Balasubramanyam

Faculty, Staff and Students Publications

Over the past 4 decades, the clinical care of people living with HIV (PLWH) evolved from treatment of acute opportunistic infections to the management of chronic, noncommunicable comorbidities. Concurrently, our understanding of adipose tissue function matured to acknowledge its important endocrine contributions to energy balance. PLWH experience changes in the mass and composition of adipose tissue depots before and after initiating antiretroviral therapy, including regional loss (lipoatrophy), gain (lipohypertrophy), or mixed lipodystrophy. These conditions may coexist with generalized obesity in PLWH and reflect disturbances of energy balance regulation caused by HIV persistence and antiretroviral therapy drugs. Adipocyte hypertrophy characterizes visceral …

Journal of Community Hospital Internal Medicine Perspectives

Streptococcus canis is an uncommon human pathogen, but documented infections have been mostly associated with exposure to dogs. There are only five documented cases of endocarditis secondary to streptococcus canis, with all cases except one documenting exposure to a canine. We present a 74-year-old male with a history of Type 2 diabetes mellitus, CKD 3, moderate aortic stenosis and remote exposure to agent orange, who was found to have Streptococcus canis native valve endocarditis without exposure to a dog. To the best of our knowledge this case is the first case of endocarditis linked to feline exposure.

Patients with cirrhosis that are hospitalized with COVID-19 infection have been found to have worse outcomes. No comparative study has been conducted between gastrointestinal (GI) bleeding in patients with cirrhosis who are diagnosed with COVID-19. We utilized the National Inpatient Sample (NIS) database to perform a retrospective analysis of 24, 050 patients diagnosed with cirrhosis and COVID-19. The identified patients were separated into variceal bleeding, nonvariceal bleeding, and no (or neither) GI bleeding groups. After performing propensity sample matching and multivariate analysis of mortality, we found no significant differences in mortality among the three groups. However, the variceal bleed group …

Perceived Moral Distress Among Patient-Facing Healthcare Professionals During The Covid-19 Pandemic, Sarah Sumner, Karen Colorafi, Teresa Rangel

Providence Nursing Research Conference 2023 – Present

Background:

The most common framework for ethical decision-making in healthcare is principalism which is founded on three ethical traditions: utilitarianism, achieving the most good for the most people; deontology, upholding moral obligations to individuals; and virtue ethics, doing what is virtuous regardless of the consequences. Principalism is further guided by four principles: 1) respect for autonomy; 2) beneficence, the duty to do good; 3) nonmaleficence, the duty to do no harm; and 3) justice, the duty to treat similar cases similarly. Patient-facing healthcare professionals (HCPs) commonly expect all moral values will be considered when decisions are made that impact patients …

Vaccine Hesitancy Among Youth Living With Hiv In Detroit, Madeline B. Simone

Medical Student Research Symposium

Vaccine hesitancy among youth with human immunodeficiency virus (HIV) was evaluated to determine if the pandemic affected vaccine acceptance. A retrospective chart review was conducted to analyze vaccine rates over a five-year (pre-post COVID) in one university-based clinic. Results indicated a variation in acceptance rates between vaccines, with the MenACWY, MenB, tetanus, and HPV having the highest acceptance rates and COVID-19 and annual flu vaccine having the lowest acceptance rates. Vaccine hesitancy did not correlate with HIV treatment hesitancy nor with aversion to needles. Negative messaging around vaccines from a variety of sources appeared to be the primary factor in …

Management Of Sepsis With The Quick Sequential Organ Failure Assessment, Jeanna Adams

Providence Nursing Research Conference 2023 – Present

Abstract

Background:

Sepsis can be a source of morbidity and mortality particularly when there are delays in treatment. Early identification may improve time to antimicrobial administration. The quick Sequential Organ Failure Assessment (qSOFA) is an evidence-based practice screening tool that, when in used in conjunction with the Systemic Inflammatory Response Syndrome (SIRS) criteria can enhance recognition and treatment of sepsis. On a suburban Southern California hospital Neurological/Telemetry Unit the qSOFA is automatically calculated in the electronic medical record (EMR) but the bedside nurses were unaware of its availability and value. In addition, sepsis was not being identified in a timely …

Staphylococcus Aureus Oleate Hydratase Produces Ligands That Activate Host Ppara, Christopher D. Radka, Matthew W. Frank, Tyler S. Simmons, Cydney N. Johnson, Jason W. Rosch, Charles O. Rock

Markey Cancer Center Faculty Publications

Commensal gut bacteria use oleate hydratase to release a spectrum of hydroxylated fatty acids using host-derived unsaturated fatty acids. These compounds are thought to attenuate the immune response, but the underlying signaling mechanism(s) remain to be established. The pathogen Staphylococcus aureus also expresses an oleate hydratase and 10- hydroxyoctadecanoic acid (h18:0) is the most abundant oleate hydratase metabolite found at Staphylococcal skin infection sites. Here, we show h18:0 stimulates the transcription of a set of lipid metabolism genes associated with the activation of peroxisome proliferator activated receptor (PPAR) in the RAW 264.7 macrophage cell line and mouse primary bone marrow-derived …

Best Practices For Helicobacter Pylori Management, David Y Graham

Faculty, Staff and Students Publications

For decades, antimicrobial therapy for Helicobacter pylori infection has been given empirically, and the results of therapy (success or failure) have either not been confirmed or when confirmed have not been used to modify prescribing behavior. These practices coupled with increasing antibiotic resistance have resulted in low cure rates overall. Susceptibility testing for H pylori has increasingly become available, especially in the United States. Availability of susceptibility-based therapy has encouraged adoption of the principles of antimicrobial stewardship for H pylori infection (eg, limiting antibiotic choice to antibiotics for which the infection is susceptible given at optimal doses, formulations, frequency of …

T cell receptor engineered T cell (TCR T) therapies have shown recent efficacy against certain types of solid metastatic cancers. However, to extend TCR T therapies to treat more patients across additional cancer types, new TCRs recognizing cancer-specific antigen targets are needed. Driver mutations in AKT1, ESR1, PIK3CA, and TP53 are common in patients with metastatic breast cancer (MBC) and if immunogenic could serve as ideal tumor-specific targets for TCR T therapy to treat this disease. Through IFN-γ ELISpot screening of in vitro expanded neopeptide-stimulated T cell lines from healthy donors and MBC patients, we identified reactivity towards 11 of …

Crises In Antimicrobial Stewardship: Misuse Of Clarithromycin For Helicobacter Pylori Therapy, David Y Graham

Faculty, Staff and Students Publications

Helicobacter pylori is a class I carcinogen that infects more than 100 million individuals in the United States. Antimicrobial therapy for H. pylori has typically been prescribed empirically rather than based on susceptibility testing. Until recently, therapeutic recommendations have generally ignored the principles of antibiotic stewardship. A combination of a proton pump inhibitor (PPI), amoxicillin, and clarithromycin (triple therapy) remains popular despite increasing clarithromycin resistance and poor cure rates. Concomitant therapy (a PPI, amoxicillin, clarithromycin, and metronidazole) is recommended and widely used despite all patients receiving at least one unneeded antibiotic. In 2020, the Food and Drug Administration approved vonoprazan, …

Peroxisome Proliferator-Activated Receptors As Therapeutic Target For Cancer, Yuqing Wang, Feifei Lei, Yiyun Lin, Yuru Han, Lei Yang, Huabing Tan

Faculty, Staff and Student Publications

Peroxisome proliferator-activated receptors (PPARs) are transcription factors belonging to the nuclear receptor family. There are three subtypes of PPARs, including PPAR-α, PPAR-β/δ and PPAR-γ. They are expressed in different tissues and act by regulating the expression of target genes in the form of binding to ligands. Various subtypes of PPAR have been shown to have significant roles in a wide range of biological processes including lipid metabolism, body energy homeostasis, cell proliferation and differentiation, bone formation, tissue repair and remodelling. Recent studies have found that PPARs are closely related to tumours. They are involved in cancer cell growth, angiogenesis and …
