Filter by:STUDY HYPOTHESIS : An infection prevention program adapted for the nursing home context can reduce by 5% the number of infections (urinary, upper and lower respiratory and gastrointestinal) in elderly residents in nursing homes. STUDY DESIGN : The proposal is for an interventional cluster (nursing home) study comprising 2 randomized groups: group 1 (interventional), comprising 25 nursing homes implementing a specific infection prevention program; and group 2 (control), 25 nursing homes continuing to implement their routine prevention measures.
The purpose of this study is to determine if the Childsmile programme (www.childāsmile.org) with the additional maternal use of xylitol is more effective at reducing dental decay in children than a Childsmile program alone. The children will be compared in the two groups at age two, to determine how the interventions affected the early colonization of mutans streptococci, an important risk factor of tooth decay. At three and at five years the investigators will also examine the amount of tooth decay in these children. Using MIDAS (Scotland's national health service dental data) records, the investigators will follow the oral health of the children until the age of 5 years. Main hypothesis: The maternal consumption of xylitol reduces early childhood caries
This trial is to determine the safety of valacyclovir in persons with chronic hepatitis C and herpes simplex type 2 infection. Participants will be randomized to valacyclovir or matching placebo. After receiving the initial therapy for eight weeks, the participants will cross over to the alternate therapy for an additional eight weeks. Each treatment period will be separated by a two-week period of daily placebo. The hypothesis is that treatment with valacyclovir will result in a significant reduction in serum levels of hepatitis C virus ribonucleic acid.
The purpose of this study is to assess the impact of disseminating information on comparative performance, along with actionable messages on how to improve health outcomes, to district-level decision-makers in India using a randomized, controlled design. This information should improve prioritization of health services by district health officers, budget allocation for health, and implementation of priority health services at the district level.
Infections are common causes of morbidity and mortality in pediatric cancer patients. Today, there are limited data on the incidence, distribution of specific infections, causative agents and risk factors for severe infections in this population. Moreover, little data exist on the epidemiology of infections among pediatric patients with solid tumors. The objectives of the present study are to define the incidence, categories of infections by organ systems, etiologic agents and risk factors for infections in different pediatric malignancies. The results of this study will help the investigators to better understand the epidemiology of infections in the different types of pediatric malignancies, enable the investigators to identify high risk patients, and design a better approach to empiric treatment of these patients. A prospective, multi-center study, conducted in 5 pediatric hematology-oncology units across Israel (Rambam Medical Center, Haemek Medical Center, Schneider Children's Medical Center, Hadassah Medical Center, Soroka Medical Center). All children aged 0-18 years of age, newly diagnosed with cancer and admitted to day care or inpatient departments with fever of >38.0 C will be included in the study. Demographic, clinical and microbiological figures will be collected in each center by a research assistant supervised by the infectious disease specialist. Data will be collected according to a pre-defined Patient Data Form and entered into an electronic data base that will be analyzed accordingly. In each event of febrile episode during chemotherapy, the following data will be collected by a research assistant using a patient data form and computerized software: - Demographic data: age, gender, ethnicity. - Clinical data: Underlying disease, immunizations, prophylactic antibiotics, presence of central venous catheter, intensity of chemotherapy, duration of fever, duration and severity of neutropenia, diagnosis of present event. - Imaging data - Microbiological data - Outcome The statistical analysis will be performed by an epidemiologist and statistician using the SPSS 12.0 software.
Bundling infection control interventions should decrease incidence of Healthcare-Associated Infections in General Medical Wards at Siriraj Hospital, Bangkok, Thailand
The objectives of the study were: 1. To study risk factors for colonization and infection with antibiotic resistant bacteria among patients with severe IAI before and after antibiotic treatment and surgical intervention. 2. To study species changes in the rectal flora among patients with severe IAI before and after antibiotic treatment and surgical intervention. 3. To review guidelines for antibiotic use in participating units. 4. To evaluate surgical antibiotic prophylaxis and treatment in relation to risk for colonization and infection with antibiotic resistant bacteria among patients with severe IAI 5. To use the results from the study in the process of a more appropriate use of antibiotics in participating units and care of patients with severe IAI. 6. To study the dynamics of extended-spectrum beta-lactamase producing and wild-type Enterobacteriaceae in patients with suspected severe intra abdominal infections before, during and after antibiotic treatment.
Opportunistic infections are caused by bacteria, mycobacteria, fungi or viruses that do not normally cause infections in people with healthy immune systems. Some of these infections can cause public health concerns, especially in areas with limited access to treatment. People who acquire opportunistic infections usually have diseases that affect their immune systems, such as human immunodeficiency virus (HIV), or do not have enough white blood cells to fight the infection. However, some people acquire opportunistic infections even though they have normal amounts of white blood cells and are free from known diseases that harm their immune systems. This study will investigate some of the reasons that otherwise healthy people get opportunistic infections to learn more about why some people are more likely to have them. This study will include up to 210 HIV-negative males and females older than 18 years of age who have opportunistic infections. The patients will be drawn from multiple sites in Thailand and Taiwan including Khon Kaen University Hospital, Siriraj Hospital, Ramathibodi Hospital, National Taiwan University Hospital, National Cheng-Kung University Hospital Patients will undergo an initial evaluation that will include a physical examination, medical history, and blood and urine testing. Additional tests will be conducted if the researchers consider that the tests are medically necessary to treat the opportunistic infection; the results of the tests will be reviewed and saved for study purposes. Depending on the severity of the infection, the initial evaluation may take more than 1 day to complete. After the evaluation, patients will be given standard and appropriate medicines to treat the infections. Patients will return for follow-up visits to allow researchers to monitor their condition and to assess how well the patient is responding to the treatment. Patients will be evaluated by the study researchers at least once a year for 2 years following the initial treatment.
To evaluate clinical and immunological outcome of children treated with HAART.
The number of patients requiring joint replacement is increasing due to its success in restoring function and pain relief, and the growing population of the elderly. One of the most serious complications of arthroplasty is joint prosthesis infection. Due to the absence of prospective, randomized, controlled studies, there is no consensus concerning diagnosis and treatment of prosthetic joint infections. The main objective of this trial is to evaluate the clinical efficacy of rifampin combination therapy versus monotherapy using cloxacillin or vancomycin in early staphylococcal infections after total hip and knee arthroplasty.
