Active clinical trials for "Communicable Diseases"

Radio(chemo)therapy is the standard therapy for both, brain tumors and brain metastases. Neurological decline is observed in these patients and tumor progression or radiotherapy side effects have been made responsible for this. However CMV encephalitis may also be a reason. Therefore the investigators aim to analyze the CMV status in patients during and after radio(chemo)therapy. It will be checked by CMV-DNA (PCR analysis) and CMV antibodies (IgG and IgM ELISA) in the blood of the patients. These findings will be correlated with changes in the brain, visualized by MRI. In addition a detailed immunophenotyping in the peripheral blood will be performed.

This 4-year cluster randomized controlled trial aims to determine whether implementation of Evidence-based Practice for Improving Quality (EPIQ) method can reduce hospital-acquired infection in Chinese Neonatal Intensive Care Units (NICUs).

The purpose of this clinical trial study is to assess, among young and sexually active women presenting recurrent urinary tract infection (UTIs), efficacy of an optimal dose of cranberry extract quantified and standardized to 37 mg/day of Proanthocyanidins (PACs), compared to a control dose quantified and standardized to 2 mg/day of PACs on mean number of new UTIs during a 6-month follow-up period.

The aim of this study is to evaluate the influence of Primary and Secondary Prevention of Respiratory Infections in children up to 3 years-old attending daycare.

Cytomegalovirus is the most important opportunistic infection after kidney transplant, with increased in mortality, morbidity and higher costs of transplantation. Despite the favorable efficacy (lower acute rejection) results of the most worldwide used regime, tacrolimus, mycophenolate and prednisone, or the investigators local common regimen, tacrolimus, azathioprine and prednisone, this combinations are associated with higher incidence of cytomegalovirus infection, disease and recurrence. Namely, sirolimus use is associated with decreased risk of cytomegalovirus infection/disease, and there is not a prospective cohort to evaluate the conversion to sirolimus efficacy to decrease the cytomegalovirus infection recurrence. Given this, the investigators propose a study of their own initiative that attends local needs: evaluate the conversion to sirolimus efficacy in decrease the cytomegalovirus recurrence after kidney transplant.

Multicenter observational survey of the presence of Human Papilloma Virus (HPV) on trans vaginal ultrasound (TVUS) probes, and of the behavior of professionals during US examination and probe disinfection. This will allow modeling the risk of HPV transmission, and could contribute establishing future guidelines for reducing the risk of transmission of microorganisms and the risk of infection through TVS.

Febrile neutropenia (FN) is a clinically important adverse effect of myelosuppressive chemotherapy. If patients present with FN, attention is focussed on well-recognized sites of origin of infection: the airways, urinary tracts, and skin. However, infections can be only documented clinically in about two-third of febrile episodes, whereas a causative microbial pathogen cannot be identified in the majority (>70%) of cases. Pre-treatment oral evaluation aimed to identify and eliminate oral/dental foci is only routinely used in patients at high risk for oral complications (i.e. head and neck cancer patients and stem cell transplantation recipients). However, any patient treated with myelosuppressive chemotherapy, be it for cure or palliation, is at risk of developing infection in and/or originating from the oral cavity. Nevertheless, in these patients dental screening is somewhat randomly employed at the oncologist's discretion. More insight into the pre-treatment oral condition and its potential role in FN is mandatory, particularly considering the growing numbers of older patients retaining their natural dentition and the increase of dental diseases and cancer incidence with age. In addition, oral diseases may aggravate chemotherapy-induced oral mucositis (OM). OM is associated with an inflammatory response, which together with ulcerations providing a portal of entry for bacteria, can result in FN and systemic inflammatory syndrome (SIRS) and/or sepsis. Evidence suggests that microorganisms are involved in the pathobiology of OM, but no longitudinal studies using open-end sequencing are available. Furthermore, comparing bacteria identified in blood cultures in febrile patients with those of the oral cavity will expand the knowledge on the role of the oral cavity as a potential source of bacteremia. The investigators expect that the results will provide a scientific base for subsequent intervention studies on the efficacy of dental screening and elimination of foci, and other interventions aimed at modifying the oral environment before and during chemotherapy.

The purpose of this study is to determine if the infiltration of 0.5% Bupivacaine in the surgical wound is effective to diminish the pain and the risk of surgical site infections in patients who go to a open gastrointestinal procedure.

This study aims to determine whether a cranberry concentrate reduces recurrent urinary tract infections (UTIs) in women. Approximately 150 adult women will be recruited to participate in this study. Subjects will be randomized to either the cranberry supplement or placebo treatment for 12 months. Subjects and investigators will be blinded to which supplement they are taking.

The main questions being addressed are (1) how patient reported outcomes change during treatment for HCV, (2) how treatment impacts liver function and liver status, and (3) how much treatment costs from the payer's perspective and the patient's perspective. The hypothesis being tested is that treatment has a negative effect on the quality of life during treatment. The negative effect is expected to be temporary. Successful treatment, which is equated with a virological cure of the infection, is expected to result in an improvement in quality of life compared to baseline and to improvement in markers of liver function and liver status. Costs of treatment are expected to be $80,000-$200,000 per virological cure.
