Filter by:Patients with sepsis (2 or more systemic inflammatory response syndrome criteria and suspected infection) assessed in the emergency department have blood cultures obtained to identify potential blood stream infections (BSI). Blood cultures are expensive, sometimes inaccurate, and only positive about 10% of the time in the emergency department. This study evaluates the effect of physician knowledge of C-reactive protein (CRP) levels on ordering rates of blood cultures in emergency department patients with sepsis. All patients with sepsis will have CRP levels measured using a point-of-care device, prior to blood tests being ordered. Half of participants will have their CRP level available to the emergency physician and half will not. Blood culture ordering rate and safety outcomes will be compared between these two groups.
Total joint replacement is considered one of the most successful surgical procedures in the field of orthopedics. Despite this achievement, prosthetic joint infections is still considered a severe complication often leading to catastrophic results and requiring repeated and extensive treatment. The incidence of PJI (a prosthetic joint infection) varies depending on the joint involved; the rate of arthroplasties becoming infected is as follows: 1.7% of primary and 3.2%of non-primary hip arthroplasties. The accurate diagnosis of prosthetic joint infection often involves the combination of multiple factors including symptoms, signs, synovial fluid cell count, serum inflammatory markers, and culture. The sensitivity of synovial fluid culture is only 85%, so a negative culture does not rule out infection. However, the specificity of synovial fluid culture is approximately 95%, and positive cultures often imply the presence of prosthetic joint infection. The synovial fluid alpha-defensin test is an immunoassay that was specifically developed to aid in the diagnosis of prosthetic joint infection . The sensitivity and the specificity of the alpha-defensin immunoassay test have been reported to be above 96%. Molecular diagnostic tests using polymerase chain reaction (PCR) are emerging as a tool for the diagnosis of infections and noninfectious conditions. The application of PCR techniques with primers derived from the highly conserved regions of the bacterial 16S rRNA gene has been useful in the detection of bacterial organisms. Use of broad-range 16S rRNA gene PCR as a tool for identification of bacteria is possible because the 16S rRNA gene is present in all bacteria . Aim of the work: .Determine sensitivity and specificity of alpha defensing and 16S rRNA gene in diagnosis of prosthetic joint infection. - Detection of antibiotic sensitivity for different organisms isolated from synovial fluid
Faecal microbiota transplantation (FMT) is used for recurrent Clostridium difficile infection (rCDI) as part of an quality improvement initiative and conducted within the framework of Center for Faecal Microbiota Transplantation at Aarhus University Hospital (CEFTA).
The purpose of this study is to determine the safe use and evaluate the efficacy/performance of DAV132 in hospitalized patients at high risk for Clostridium difficile infection (CDI) and who receive fluoroquinolones (FQs) for the treatment of acute infections or for prophylaxis of febrile neutropenia.
Septic pathology is an extremely frequent reason for consultation in our emergency services, with an annual incidence of severe forms between 50 to 95 cases per 100,000 inhabitants and a constant increase estimated at 9% per year. Diagnosing these patients early and precisely is a major challenge for the clinician, as this diagnosis will lead to more or less aggressive medical management. The criteria of S.I.R.S, used to define and to sort patients in sepsis according to the old definition, were completely abandoned in the last recommendations for lack of specificity but also of sensitivity. The latest recommendations suggest using another score, the "Quick Sepsis Related Organ Failure Assesment (qSOFA) score", in order to early detect septic patients at risk of poor progress. However, the recent literature highlights a very low sensitivity of the qSOFA score for the screening of septic patients, ranging from 30 to 60% according to the studies. In addition to qSOFA, other scores are described in the literature with apparently higher sensitivity, and thus seem more suitable for our daily practice. Among them is the NEWS score or the RETTS score. Each of these scores is again based upon the values of vital signs recorded as soon as the patient arrives in the emergency department. To date, very few studies have been interested, in a prospective way, in the sensitivity and the specificity of these different scores to diagnose the "infected" patients in the emergency departments. Therefore a non-interventional, prospective, multicenter cohort study is carried out here, in order to be able to compare, on the same cohort of patients admitted into emergency services, the diagnostic performance of these different scores with respect to the presence or absence of an infection. The aim of this study is to define the best clinical score to use in emergency medicine to quickly diagnose the infected patients, and offer them the best medical care.
Purpose of the study: • To obtain additional data on the efficacy and safety of Anaferon in the treatment of acute respiratory viral infections.
Negative pressure wound dressings have been studied and shown to have applications in decreasing rates of surgical wound infections. This study studies the effect of a low cost needle-aspirated negative pressure compression dressing on rates of wound infection at prior ostomy site in patients undergoing ostomy reversal surgery.
24 healthy volunteers will be immunized with three times 50 L3 larvae or placebo followed by treatment with albendazol and subsequently challenged with twice 50 L3 larvae.
Background: Abdominal wall reconstruction in patients presenting with enteric fistulas and mesh infection is challenging. There is a consensus that synthetic mesh must be avoided in infected operations. The alternatives to using synthetic mesh, such as component separation techniques and biologic mesh, present disappointing results with expressive wound infection and hernia recurrence rates. Methods: A prospective clinical trial designed to evaluate the short and the long-term outcomes of patients submitted to elective abdominal wall repair with synthetic mesh in the dirty-infected setting, and compared to a cohort of patients submitted to clean ventral hernia repairs.
This is a single site, prospective, observational study that seeks to assess changes in mucosal immunity that occur as a result of HIV-1 exposure, HSV-2 infection, and/or pre-exposure prophylaxis (PrEP) usage to prevent HIV-1 acquisition. The study will collect mucosal and peripheral blood samples for a detailed analysis of longitudinal immune responses, while also obtaining samples for genetic characterization to understand how variants in CD101 and UBE2V1 may modulate host mucosal responses and HIV-1 infection risk.
