8 Clinical Trials for Various Conditions
This is a case-control study designed to evaluate the role of anatomic site, gender and race in human papillomavirus-associated head and neck squamous cell cancers (HNSCC). We will explore the role of HPV, tobacco, alcohol and drug use, in HNSCC by tumor site with particular emphasis on the sinonasal cavity as well as differences in risk factors for HPV-positive HNSCC by gender and race.
As the global and pandemic spread of the novel coronavirus (SARS-CoV-2, COVID-19) continues, many knowledge gaps remain with regard to the epidemiology and transmission of infection, as well as the normal immunological responses after viral exposure. Cincinnati had its first confirmed case of COVID-19 on March 14, 2020, and despite extensive shelter-in-place and social distancing efforts, community spread continues at over 150-200 new cases per week. As new residents and fellows arrive in July 2020 to Cincinnati Children's Hospital Medical Center (CCHMC), many of whom come from metropolitan areas across the country, it is imperative that investigators determine the current prevalence of infection, measure the cumulative incidence of infection over the next 12-24 months, investigate the normal antibody patterns after infection, and help elucidate what constitutes a protective immunological response. The investigators have a unique but time-limited opportunity to optimally track the epidemiology and natural history of SARS-CoV-2 infection among trainees at CCHMC, including risk factors for transmission and immunological recovery. SCREEN will investigate epidemiological and immunological features of SARS-CoV-2 virus infection within the cohort of CCHMC residents and fellows who have patient contact. By collecting and analyzing weekly serial samples for SARS-CoV-2 (nasal swab for virus by PCR) and monthly serological exposure (serum antibodies by ELISA), the investigators will determine the prevalence and cumulative incidence of infection by SARS-CoV-2; the investigators will also document the antibody responses over time and identify cases of apparent viral recrudescence or re-infection.
The primary objective is to assess the ability of COVID-19 IgG and IgM assays to detect an immune response in COVID-19 patients in the Henry Ford Health System (HFHS), both during hospitalization and over the following 12 months.
The goal of this study is to understand the infectious exposure of SARS-coronavirus 2 (SARS-CoV2) among surgeons and anesthesiologists and to correlate this status with self-reported indices of COVID-19 illness.
This will be an investigation to determine the quality of the serological immune responses against Propionibacterium acnes (P. acnes) in acne patients compared to healthy individuals. In particular, the investigators will measure serum antibody titers against P. acnes surface antigens, and the efficiency of antibody-mediated phagocytic killing of P. acnes.
The primary objective of this study is to determine the magnitude and breadth of the serum antibody response to the nonavalent HPV vaccine (Gardasil-9) in adults with well-controlled HIV infection. The secondary objectives of the study are to observe short term clinical outcomes of prevalent HPV genotype-specific anogenital infections in adults living with HIV who complete the three-dose Gardasil-9 vaccine series, and to determine the protection afforded by Gardasil vaccine over time in previously vaccinated adults living with HIV. The clinical hypothesis is that adults with virologically controlled HIV mount a serum antibody response to the nonavalent HPV vaccine that is comparable to HIV negative counterparts. We also postulate that HPV vaccination will provide short-term clinical benefit against HPV infections and disease associated with vaccine genotypes and continuing protection against vaccine genotypes of HPV over time.
The primary goal for this study is to assess whether receiving the results of an antibody test changes protective behavior to avoid SARS-CoV-2 infections (i.e., mask-wearing, physical distancing, limiting close contacts/avoiding crowds, hand-washing, avoiding contact with high-risk individuals). While studies have been published on the cross-sectional relationship between risk perception and other demographic characteristics and health behaviors that are protective for SARS-CoV-2 infection (see citations), there have been no studies showing the effect of receiving information about antibody positivity on protective behavior. Not only can results from this study be used to better model transmission, a better understanding of college student's risk perception around SARS-CoV-2 infections has implications for future vaccination strategies as well. There are concerns that a desire to return to "normal" life in combination with reduced perception of risk could have negative consequences for uptake of vaccination (Johns Hopkins Center for Health Security 2020 report, The Public's Role in COVID-19 Vaccination: Planning Recommendations Informed by Design Thinking and the Social, Behavioral, and Communication Sciences). The antibody test used in this study is named 'SARS-CoV-2 IgM/IgG rapid assay kit (Colloidal Gold)'. It provides a fast, on-site, and accurate detection of IgM/IgG antibodies against SARS-CoV-2, with positive results of IgM antibodies indicating a recent infection, while positive results of IgG antibodies signaling a longer or previous infection. It can detect IgM and IgG antibodies against SARS-CoV-2 in human specimens of serum, plasma, or venous whole blood.
The Investigators propose a multi-center, observational, longitudinal, cohort study of the serology and wellness of HCWs over a year of the COVID-19 pandemic.
