Filter by:This multicenter, randomized controlled trial will compare the use of NGS and traditional culture in directing antimicrobial treatment for patients with periprosthetic joint infection.
The human BK polyomavirus is a significant risk factor for renal transplant dysfunction and allograft loss. The prevalence of BK viremia (BKV) following kidney transplantation is estimated to be 10-20%.
The investigators primary objective is to identify genetic factors that may increase the risk of patients developing a periprosthetic joint infections (PJI) following total joint arthroplasty (TJA). The investigators hope that by identifying genetic predispositions we will be able to provide patient specific care pathways to prevent or minimize the risk for PJI.
The general purpose of this initial study is to evaluate whether parametric PET/CT improves diagnosis and treatment monitoring in select diseases. The specific aim of the HYPOTHESIS GENERATION study is: 1. To obtain and compare parametric as well as traditional static PET/CT images and determine the number of lesions identified on each type of scan.
Elderly people who have multiple health problems are at higher risk of illness from viral respiratory infections, such as influenza (the flu) and COVID-19. This is especially true for residents in long-term care because the usual methods of infection control (handwashing, mask-wearing, and distancing) are difficult to enforce due to the memory problems of many residents and the frequently shared common spaces. It can also be difficult to prevent the spread of viral infections within long-term care because many residents are unable to tell their caregivers when they are feeling ill. Also, some elderly people do not show typical symptoms of infection (like fever), instead they may suddenly become confused or weak. This study will test if a safe form of ultraviolet light (far-UVC) can be effective as an extra method of disinfection (in addition to usual manual cleaning) against airborne and surface viruses that can cause respiratory infections.
iSpecimen aims to create a clinical partner network of hospitals, laboratories, academic institutions, and other healthcare organizations ("institutions") capable of providing researchers and educators ("researchers") with annotated biospecimens for use in biomarker discovery and validation; diagnostic test and instrumentation development and validation; therapeutics development; other medical research including the impact that various specimen collection and handling methods and conditions have on research results; and in education such as researcher or physician training (collectively "research").
The present work proposes to find if a bio-active composite in the hemolymph or plasma of the freshwater bivalve Anodonta cygnea is able to offer immunity and specificity for meliorating the major symptoms in human SARS and COVID-19 lineage infection. The Methodology concerns in silico procedures using organic fluids from 54 bivalves (in very specific conditions) to evaluate their therapeutic effects in 6 voluntary SARS and COVID-19 infected persons with an integrative diagnosis by a computational Mora®Nova apparatus to access the basal and experimental human physiological parameters.
There are very few long-term studies that analyze the immune responses in patients recovered from COVID-19 caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The main aim of this study is to analyze the clinical profile and immune responses of recovered COVID-19 patients in a representative cohort of people in the Umbria region of Italy. The participants had a history of testing positive for SARS-CoV-2 in March 2020 by Reverse Transcriptase- Quantitative Polymerase Chain Reaction (RT-qPCR). The participants were invited for voluntary participation in a seroprevalence study. This study analyzes longitudinally the presence of antibodies against SARS-CoV-2 by sequential serological tests at different time points using two FDA-approved Immunoassays. At the first serum sample collection, the participants were asked to provide information about their COVID-19 clinical history including clinical profile, co-morbidities, and treatment undertaken using a standardized questionnaire. Successive sequential serological assessments were conducted to understand the immune responses in these recovered patients. Moreover, stage two of the study involves, analysis of antibody titers in recovered vaccinated individuals and their follow-up.
Immunodeficiency associated with human immunodeficiency virus (HIV) infection could predispose people living with HIV/AIDS (PLHA) to defective serological responses following infection or vaccination. To evaluate the health outcomes of coronovirus disease-2019 (COVID-19) and HIV co-infection, PLHA and HIV-uninfected persons in Hong Kong are invited to join a study for understanding their clinical characteristics and for tracking their levels of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) over a one-year observation period after infection or vaccination. The results could inform the development of prevention and control strategy for PLHA in response to the emerging coronavirus threats.
The main purpose of the extension phase of this study is to evaluate the longer-term immune persistence of mRNA-1647 vaccine administered to CMV-seronegative and CMV-seropositive adults who completed Study mRNA-1647-P202 (NCT04232280). For participants in the optional booster phase (BP), the main purpose is to evaluate the long-term immunogenicity and safety of the mRNA-1647 vaccine in both participants receiving a booster dose (BD) and those not receiving a BD, and to additionally evaluate the reactogenicity in participants receiving a BD.
