Filter by:Background: Currently prevalence of HPV infections for high risk strains among young women in Switzerland is unknown. In addition, since 2008 a vaccination program to prevent these infections has been implemented in a number of cantons, but its actual population impact is currently unknown. For now, HPV screening in Switzerland is mainly performed by gynecologists or during gynecological consultation at hospital. This method is certainly effective, but expensive; population coverage of screening is still insufficient. A whole segment of the target population does not participate in this screening especially young people of foreign origin, for various reasons: economic cost, no gynecological, and for other reasons. Several studies raise the effectiveness and efficiency of self-sampling to increase coverage of screening, and the rate of participation of non-participants. Through this study, the investigators evaluate effectiveness of this vaccination on the prevalence of HPV infections using HPV prevalence kit and assess evolution of infection and clearance of HPV virus during 5 years in a population of young unvaccinated and vaccinated women. Method: During the study, each participants will perform a vaginal swab sampling by auto to research HPV. These samples will be sent to a laboratory where HPV typing is done by PCR using the Anyplex ™ II technology. The study will focus on a sample of 400 young women. Participants must complete a questionnaire containing demographic questions and their HPV immunization status. Vaccination coverage expected in this population is about 50%. Depending on the state of vaccination, two different groups will be vaccinated vs unvaccinated (200 women per group). The cases of HPV infection are then calculated for each group and compared as a function of the status of vaccination. Statistical tests will be applied McNemar's test for comparison between the HPV prevalence rates between the 2 groups. Expected Results: This study will allow us to confirm the possibility of using self-sampling as a method of screening and monitoring of HPV infections in the general population, it will also enable us to document the effectiveness of HPV vaccination by comparing prevalence rate of HPV infections among a group of young girls vaccinated and not vaccine and assess evolution of infection and clearance of HPV virus.
The results found in the literature do not allow to define objectively the indications respective for a one-step or a two-step exchange of prosthetic joint. Some criteria could help to decide for one-step exchange or two-step exchange: bacteria is/are identified, profile of the bacteria, anesthetic difficulties,.. A puncture could allow to identify the bacteria involved in the prosthetic joint infection (PJI) and an antibiotherapy for a few days can be given to the patient in order to decrease the inoculum. Then, a one-step exchange can be performed. The purpose of this study is to describe the management of patients who had a pre-treatment before a one-step exchange of their prosthetic joint.
The purpose of this prospective randomized clinical trial is to compare two currently accepted standard-of-care treatment strategies: Medical thoracoscopy as compared to instillation of intrapleural tissue Plasminogen Activator (TPA) and human recombinant Deoxyribonuclease (DNase) for the management of empyema or complicated parapneumonic effusion (CPPE) in adults.
This study aims to asses whether the rate of surgical wound infections in vascular surgery procedures involving exposure of the proximal femoral artery can be reduced using a different skin closure technique.
This study will assess the efficacy of oral vancomycin prophylaxis in preventing recurrent Clostridium difficile infection in hospitalized patients requiring oral or intravenous antibiotics for a suspected or confirmed bacterial infection.
In an effort to implement Choosing Wisely guidelines and decrease patient harm, we will implement and evaluate a clinician audit-feedback and behavioral "nudge" initiative to reduce low-value antibiotics for URIs. Using a quasi-experiment (pre-post) design, antibiotic prescriptions for URI at LAC+USC Urgent Care Center (intervention site) vs. Olive View-UCLA Urgent Care Center (control site) will used to test the effects of behavioral "nudge" on antibiotic prescribing.
This study evaluates the efficacy of prophylaxis with oral vancomycin for preventing recurrent Clostridium difficile Infection (CDI) in patients who have experienced at least one CDI episode in the last 180 days and are receiving antibiotics for a non CDI condition. Participants will be randomized to receive either placebo or oral vancomycin in addition to their prescribed antibiotic therapy.
The study aims to confirm the effectiveness of chicory-derived prebiotic inulin-type fructans on the reduction of the number of febrile infections diagnosed by the paediatrician in children.
A multicenter double-blinded, randomized, placebo-controlled, parallel-group comparative Phase II clinical study to assess safety, tolerability, efficacy and optimal dose of XC221 vs. placebo in patients with uncomplicated influenza or other ARVI during a 3-day treatment. The primary objective of the study is to demonstrate the difference in time before the onset of a sustained improvement in clinical symptoms according to the Modified Jackson Scale for ARVI and to determine the optimal dose of XC221 in the treatment of influenza and other ARVI.
This is a single-center, open label study. The primary aim of this project is to develop a controlled human malaria infection transmission model ("CHMI-trans") or "challenge model" to evaluate the capacity of vaccines, biologics (monoclonal antibodies, or mAbs), and drugs to block malaria parasite transmission by assessing infectiousness of Plasmodium falciparum (Pf) gametocyte carriers for Anopheles mosquitoes.
