Filter by:Background The risk for hospitalized infection (i.e. infection leading to hospitalization) in patients with inflammatory arthritis (rheumatoid arthritis (RA), psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA) treated with biological drugs is known to be increased compared to the background population. In daily clinical practice, there is a need for a simple way to assess the absolute risk for hospitalized infection in individual patients based on easily available information such as age, diagnosis, functional status, comorbidities and medication. This risk estimate will be useful in clinical decision making e.g. when advising patients on whether or not to initiate biologic therapy or when advising patients on influenza or pneumococcal vaccination. Objectives The objectives are 1) to assess the risk for hospitalized infection (infection leading to hospitalization) in patients with inflammatory arthritis during 12 months of follow-up after initiating treatment with their first biological drug (bDMARD) with the risk in the general population, and 2) to develop a simple, clinically useful algorithm that allows prediction of the risk of hospitalized infection in individual patients. Methods Observational cohort study based on existing data in: The Danish Rheumatology Register (DANBIO), The Danish National Patient Register, The Danish National Prescription Register and The Danish Register of Causes of Death. All patients registered in DANBIO with RA, PsA or axSpA who initiated treatment with their first biological drug between January 1, 2006 and December 31, 2016 will be identified. Baseline predictors and outcomes (hospitalized infection or death) during 12 months of follow-up are obtained. Logistic regression analysis and 10-fold cross-validation will be used to develop and internally validate the prediction model.
Controlled human malaria infection (CHMI) is an important tool for the assessment of the efficacy of novel malaria vaccines and drugs prior to field trials. CHMI also allows for the evaluation of immunity to malaria and parasite growth rates in vivo and thus allows for the assessment of the natural acquisition and loss of malaria immunity. This may be particularly useful in individuals from endemic areas with changing levels of exposure and immunity to malaria. Thus, CHMI in individuals with prior exposure to malaria could be a valuable tool to accelerate malaria vaccine development and inform malaria control programs of changing immunity levels and related disease presentations. In this trial, the investigators intend to study the effect of pre-exposure to Plasmodium falciparum (Pf) on parasite kinetics, clinical symptoms and immunity after CHMI by PfSPZ Challenge in Gambian adults. Based on a well-defined sero-profile representing the extremes of current malaria exposure in The Gambia, two cohorts will be identified to study the impact of naturally acquired immunity on susceptibility for a Controlled Human Malaria Infection.
Retrospective reports from literature have shown a lower rate of infections for transperineal versus transrectal approach for prostate biopsies in the setting of prostate cancer suspicion. The aim of this study would be to compare in a prospective randomized trial the rate of infection with transperineal versus transrectal approach.
The XN-20, is a full blood count (FBC) analyser with an extended differential counting and flagging System. The XN-Series' individual channels allow real-time reflex analysis, and uses a two stage process to classify the white blood count (WBC) sub-populations and detect the presence of abnormal reactive and malignant cells. In regards to lymphocytes in the peripheral blood, the machine has the capacity to distinguish activated from non-activated T-cell subsets using a very small volume of EDTA sample (88uL) (including remnant sample from a standard full blood count) with results available in 1.5 minutes. It is a fully automated process and can be considered as an alternative rapid flow cytometry method. Objective of the SASA study: to investigate the signal pattern of white blood cells assessed using the XN-20 full blood count platform in patients with untreated viral infections i.e. HIV, HCV and HBV. The data from the analysis will be reviewed in conjunction with patient's demographic and clinical disease characteristics with the aim of detecting characteristic cell populations that can be used in the development of system flags for future studies.
Diabetes is a frequent and serious disease, with many complications. Diabetic foot ulcers are a frequent complication. Infection of diabetic foot ulcers is common, and requires heavy medical and/or surgical treatments. Antibiotherapy is one of the main options for the treatment of the diabetic foot ulcers, but it has many side effects. The aim of this study is to evaluate effectiveness and safety of medical treatments, in this population of patients.
Stool and blood samples from patients with a non-typhoid Salmonella infection will be collected during an observation period of six months and analyzed for changes in the microbiota diversity and composition, mutation rates in the Salmonella strains and the specific immune response evoked by the infection. Findings are compared to healthy individuals and individuals with acute, infectious diarrhea caused by other microorganisms.
The triple treatment including Proton pump inhibitor (PPI) -clarithromycin and amoxicillin or metronidazole was proposed 30 years ago at the first Maastricht conference to treat helicobacter pylori (H. pylori) infection and since that time, it has become the universal and standard treatment for helicobacter pylori. However, the efficacy of this triple regimen has been seriously challenged, and they are gradually becoming ineffective
Immunocompetent subjects with high load of Epstein-Barr virus DNA (EBV-DNA) in peripheral blood will be enrolled and prospectively followed up to track the natural histories of the chronic high load of EBV virus. The primary goal of this study is to explore the association of peripheral high load of EBV with the hematological malignancies, and second goal is to investigate the genetic mechanisms of immune escape and tumorigenesis of chronic EBV infection.
This study evaluate Microbial growth on Bre-Flex versus PEEK denture base in Bilateral Maxillary bounded partial denture , half of patients will receive a framework with breflex denture base and the other half will receive a framework with PEEK denture base then evaluate the Candida growth
Well-child care is the primary source of preventative health care for children. These visits provide an opportunity for physicians to assess an infant's biomedical health, development, and behavior, as well as help ensure timely immunizations, reduce the use of acute care services, and assess and family functioning. Yet, disparities in the utilization of pediatric care exist by race, ethnicity and income in the U.S., even despite high rates of overall access to primary care. Incentives have been proposed as one way to increase utilization of preventative care for mothers and children. Diapering is another important form of preventative health care that can be particularly difficult for low-income parents due the cost of diapers, which is $70-80 per child per month, or approximately $960 per year, on average. And government programs, such as Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), Supplemental Nutrition Assistance Program (SNAP), and Temporary Assistance for Needy Families (TANF), either cannot be used to purchase diapers, or do not provide enough assistance to cover the cost of diapers and other basic needs. A family's inability to provide an adequate supply of diapers for their child is called diaper need. Nationwide, one in three families with young children report experiencing diaper need, which was found to be significantly associated with maternal stress and depression, which in turn, can have a detrimental impact on a family's health and economic success. The primary goal of this study is to conduct a randomized controlled trial of a diaper provision intervention designed to increase utilization of, and adherence to, well-child visits and reduce diaper need among low-resourced families in New Haven, CT.
