Active clinical trials for "Infections"

The purpose of this study is to determine if, among women who were treated for a prior chlamydial infection, home-based, self-collected vaginal swabs can increase rescreening for chlamydia in comparison with rescreening in the clinic. The study design is two randomized trials with enrollment at multiple family planning clinics and sexually transmitted disease (STD) clinics following a common protocol.

In kidney transplant patients, CMV infection remains the leading infectious cause of morbidity and mortality. Clinical and virological relapses are common and are involved in chronic graft dysfunction. To date, it is not certain that secondary prophylaxis allows reducing these relapses, although this prophylaxis is part of the current recommendations. Our team has recently shown that the expansion of γδ T cells in peripheral blood during CMV infection was correlated with the absence of virological and clinical relapses. Indeed, the absence of relapse was associated in 94.7% of cases with the presence of γδ T cells expansion while relapses occurred in about 90% of cases in the absence of γδ T cells expansion. These results suggest that the indication and duration of secondary prophylaxis after the curative treatment of CMV infection in kidney transplantation could be guided by the immune surveillance of γδ T cells.

Colorectal illness contributes significantly to the global burden of disease. Cancer, inflammatory bowel disease and diverticulosis result in substantial patients suffering and health care expenditures. The causes of colorectal diseases remain unclear. New data suggests that intestinal bacteria may play a major role in the causal chain for many diseases, and the research on the microbial environment in the colon in relation to bowel disease is increasingly intense although the possibility for analysis of the composition of bacteria in the gut has so far been limited. However, new analytic methods based on powerful DNA sequencing, opens new opportunities. In the surgical clinic at Danderyds hospital, Stockholm, 2500 colonoscopies are performed per year. The investigators have created a biobank with mucosal samples from patient's large bowel and will consecutively include all patients scheduled for colonoscopy during one year (N=2500). Biopsies from the colonic mucosa will be analysed in collaboration with the Clinical Genomics, Science for Life laboratory (Karolinska Institutet). In Phase 1, the association between specific bacteria and colorectal disease will be investigated (hypothesis generating phase). In Phase 2, the investigators aim to identify specific bacterial biomarkers that could be used as screening tools, and lay the ground for future new treatments for colorectal disease. Early detection and new treatment regimes would result in both significant patient benefits as well as reductions in healthcare costs.

The purpose of this study is to evaluate the use of a blood test: Karius® plasma-based next-generation sequencing test (Karius Test), to see if we can detect and measure the infection causing agent in children with musculoskeletal infections (MSKI).

FALCON is a Pragmatic multi-centre trial testing measures to reduce superficial or deep skin infection following abdominal surgery in low and middle income countries. The trial will recruit patients undergoing abdominal surgery. Recruited participants will be randomly assigned to four arms to receive different combinations of skin preparation and sutures for would closure: A. In this arm surgeon will use 2% alcoholic chlorhexidine for skin cleansing and non-coated suture for wound closure; B. In this arm surgeon will use 2% alcoholic chlorhexidine for skin cleansing and triclosan coated suture for wound closure; C. In this arm surgeon will use for operation 10% aqueous povidone-iodine for skin cleansing and non-coated suture for wound closure; D. In this arm surgeon will use 10% aqueous povidone-iodine for skin cleansing and triclosan-coated suture.

Among the causes associated with infection of hospitalized patients, surgical site infection is a complication that is potentially associated with any type of surgical procedure, it also represents an expressive burden in terms of morbidity and mortality, as well as additional costs for health care systems around the world. It is regarded that the efficiency of the pre, per, and postoperative skin preparation depends on both the adopted antiseptic and the application method, with Chlorhexidine currently being the most used drug in such preparation. However, the manner, timing, or timing of cutaneous antisepsis action is unclear. Objective: Comparing antisepsis techniques using chlorhexidine-based soap associated with ethyl alcohol and alcoholic chlorhexidine versus chlorhexidine-based soap associated with alcoholic chlorhexidine, in surgical orthopedic procedures.

Vancomycin, a novel intravenously administered antibiotic, currently plays a key role in the management of complicated multi-organism infections. However,current LC-MS/MS methods briefly describe parameters and the only reported internal standard was sometimes difficult to obtain. In our study,an updated LC-MS/MS method for the quantitative analysis of vancomycin in human serum was developed.

Pancreaticoduodenectomy is associated with high perioperative morbidity, with surgical site infection (SSIs) being one of the most common complications. A retrospective study at Hopkins on SSIs in these patients identified the rate of SSIs to be 16.7% and pre-operative bile stent/drain and neoadjuvant chemotherapy were independent predictors of surgical site infection. Patients with these factors having a predicted risk of up to 32%. Another subsequent retrospective study demonstrated that the use of negative pressure wound therapy device was significantly associated with a decrease in the rate of SSIs. The hypothesis of the investigator(s) for the current study is that placement of Prevena Peel & Place Dressing (Negative Pressure Wound Therapy, NPWT) in patients undergoing pancreaticoduodenectomy who are at high risk of SSIs will result in a significant decrease in their SSI rate.

Direct constitution of collections from various samples taken on a prospective cohort of healthy volunteers, to prepare human biological samples of known characteristics (biochemical and serological in particular) and quality controlled.

To compare the use of towels impregnated with 2% chlorhexidine gluconate in the traditional preoperative bath with 2% chlorhexidine gluconate in preventing the occurrence of surgical site infection among patients undergoing potentially contaminated elective surgery.
