Filter by: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").
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 goal of this study is to test a new way to diagnose and track treatment of spine infections caused by the bacteria Staphylococcus aureus.
Translational research aimed at improving diagnostic accuracy of musculoskeletal infection and musculoskeletal tumours using machine learning applied to clinical data, histopathological sections and genomic sequencing.
Infectious vertebral osteomyelitis are infectious diseases of the vertebral bone, intervertebral disc and/ or adjacent tissue. Most of cases are due to hematogenous dissemination of pathogen but direct inoculation is an aetiology after surgery. Majority of cases concern adults after 50 years and the annual incidence ranging between 0.5 and 2.4 cases per 100 000 habitants in Europe but seems to increase during last 20 years. The infectious spondylodiscitis is an important source of morbidity and mortality. The treatment is based on pathogen adapted antimicrobial therapy, which may be associated with bedrest. Surgical act is necessary when neurological complication occurs or when vertebral column instability is too important. The immobilization in bed is use to limit pain and neurological complications. However, the immobilization is based on few literature data and causes important complications especially in elderly. The of immobilization in Nancy universitity hospital changed in 2019 after institutional recommendations based on expert opinion which recommend an early verticalization of uncomplicated spondylodiscitis. The investigators aimed to evaluate the consequences of this practice change on the hospitalization duration and complication rates due to spondylodiscitis and immobilization.
Management of periprosthetic joint infection (PJI) commonly includes 6 weeks of intravenous (IV) antibiotics after surgical treatment. However, there is little evidence to suggest that oral (PO) therapy results in worse outcomes. This study aims to determine whether or not PO antibiotics are non-inferior to IV antibiotics in treating PJI. The study is a multicenter, parallel-group, randomized (1 : 1), open-label, non-inferiority trial. The non-inferiority margin will be set at 10%. Adults with a clinical diagnosis of PJI according to the International Consensus Meeting (ICM) criteria who would ordinarily receive at least 6 weeks of antibiotics and have received ≤ 7 days of IV therapy from surgery will be included. A total of 308 participants will be centrally computer-randomized to PO or IV antibiotics to complete the first 6 weeks of therapy. Follow-on PO therapy will be permitted in either arm. The primary outcome is the proportion of participants experiencing treatment failure within 1 year. An associated cost-effectiveness evaluation including complications, resource utilization and quality-of-life data will be performed.
In this study, patients undergoing ear surgery (cochlear implantation, stapedotomy, tympanoplasty) will be randomized to one of two antibiotic treatment groups. One group will receive a single treatment with an antibiotic at induction The other group will receive the single intravenous treatment, plus a one week course or oral antibiotic
Prior studies investigating the etiopathogenesis of surgical site infection (SSI) traditionally suggested three main ways for the infection to occur: local contamination occurring during the surgery, hematogenous translocation of bacteria during concomitant bacteraemia, and contamination from adjacent infected tissues by the progression of the infective process. While most of the research on SSI focused on minimizing any source of pathogens at the time of the surgery, emerging evidence shows how acute and chronic SSI can emerge more often from bacteraemia or other tissues in the body, such as the gastrointestinal system, especially when dysbiosis and high permeability are retrieved. Intercellular tight junctions (TJs) tightly regulate paracellular antigen trafficking. TJs are extremely dynamic structures that operate in several critical functions of the intestinal epithelium under both physiological and pathological circumstances. This paradigm was subverted in 1993 by the discovery of zonula occludens 1 (ZO-1) as the first component of the TJ complex 11 now being comprised of more than 150 proteins, including occludin, claudins, junctional adhesion molecules (JAMs), tricellulin , and angulins . However, despite major progress in our knowledge on the composition and function of the intercellular TJ, the mechanisms by which they are regulated are still incompletely understood. One of the breakthroughs in understanding the role of gut permeability in health and disease has been the discovery of zonulin, and the only physiologic intestinal permeability modulator described so far. Since then, zonulin has been used as a marker for increased intestinal permeability and associated with soluble CD14 (sCD14) and lipopolysaccharide (LPS), other common markers associated with surgical complication, inflammation, and bacterial translocations. As such, Zonulin could be a biomarker for mid- and long-term complications after total joint replacement such as infection, loosening, and mechanical complications associated with painful symptomatology.
