Filter by:Objectives: 1. Describe the molecular epidemiology of Clostridium Difficile infection in children in the Chicago area. 2. Determine the clinical spectrum and risk factors for Clostridium Difficile infection secondary to particular endemic strains in children. 3. Define the risk factors for recurrent and community-associated Clostridium Difficile infection in children.
On joint orthopaedic hardware infections are one of the most frequently encountered complications in orthopaedic surgery. However 6% of the cultures remain sterile, etiological diagnosis cannot be established despite obvious signs of infection. As part of this research project, we have developed a new strategy diagnosis including directly the use of PCR to reduce the number of negative results. This should have a major therapeutic impact in terms of timeliness and specificity of antibiotic. Primary: Evaluate the effectiveness of the new diagnostic strategy on etiological identification of prosthesis infections. Hypothesis: Minimum 6 percent increase in the number of patients with an etiological diagnosis of infection on prosthesis.
Patients who have undergone lung transplantation are at an increased risk of developing chest infections due to long-term medication suppressing the immune response. In other chronic lung diseases such as cystic fibrosis (CF) and bronchiectasis, inhaled, nebulised mucolytic medication such as dornase alfa and isotonic saline are often used as part of the management of lung disease characterized by increased or retained secretions. These agents act by making it easier to clear airway secretions, and are currently being used on a case-by-case basis post lung transplantation. To the investigators knowledge, these agents have not been evaluated via robust scientific investigation when used post lung transplant, yet are widely used in routine practice. Patients post lung transplant must be investigated separately as they exhibit differences in physiology that make the clearance of sputum potentially more difficult when compared to other lung diseases. Lower respiratory tract infections are a leading cause of hospital re-admission post lung transplant. Therefore, this highlights the need for a randomized controlled trial. The aim of this study is to assess the efficacy of dornase alfa, compared to isotonic saline, in the management of lower respiratory tract infections post lung transplant. Investigators hypothesize that dornase alfa will be more effective than isotonic saline. The effect of a daily dose of dornase alfa and isotonic saline will be compared over a treatment period of 1 month. Patients admitted to hospital suffering from chest infections characterized by sputum production post lung transplant will be eligible for study inclusion. Patients will be followed up through to 3 months in total to analyze short-medium term lasting effect. Investigators wish to monitor physiological change within the lung non-invasively via lung function analysis whilst assessing patient perceived benefit via cough specific quality of life questionnaires. These measures will be taken at study inclusion and repeated after 1 month and 3 months. Day to day monitoring will be performed via patient symptom diaries, incorporating hospital length of stay and exacerbation rate. The outcomes of this study have the potential to guide clinical decision-making and highlight safe and efficacious therapies.
The hypothesis is that application of Mupirocin to the nose before and after coronary artery bypass grafting surgery will reduce the incidence of surgical site infections.
TD-1607, administered intravenously as multiple ascending doses, will be investigated in healthy subjects to assess its tolerability, safety, and pharmacokinetics.
This clinical trial studies anal human papillomavirus (HPV) tests in screening for cell changes in the anus in patients with human immunodeficiency virus (HIV). Screening tests may help doctors find cancer cells early and plan better treatment for anal cancer. Completing multiple screening tests may help find the best method for detecting cell changes in the anus.
We need human blood to understand the immune response to infection and to test promising new vaccines against infectious diseases in the laboratory. One test is called the Serum Bactericidal Assay (or SBA), which is measure of how effective antibodies are at killing certain bacteria and can be an important measure of how effective a new vaccine may be. The samples would be used in the laboratory analysis of clinical trials of vaccines used in adults and children, and some samples in pre-clinical (animal) experiments testing new vaccines before they enter human-stage testing. Most people have some form of protection against most bacteria already, so not everyone is a suitable blood donor for this laboratory test. We therefore start by taking a small blood sample and test this one before asking for more blood if we found yours suitable for the work we do.
The primary objectives of this study are to assess the safety of ABT-450/r/ABT-267 with and without ABT-333 coadministered with and without ribavirin (RBV) for 12 and 24 weeks in HCV GT1- or 4-infected participants with HIV-1 coinfection and to evaluate the percentage of subjects achieving HCV ribonucleic acid (RNA) < lower limit of quantification (LLOQ) 12 weeks following treatment.
The primary goal of this project is to improve the process for contacting patients that test positive for a sexually transmitted infection (STI) in the emergency department by using text messaging. We believe patients that are contacted by both a phone call and a text message will be reached more often and they will be reached sooner than those that only receive a phone call or only a text message. In addition, patients will be given reminder cards at the time of testing to remind them that they will be contacted within 7 days if they test positive. Half of the reminder cards will have a number to call for test results. We believe patients that receive a card with a number are more likely to be contacted within 7 days.
In the past 70 years antibiotics have served as the first line of defense against infectious diseases. However, antibiotics are only effective against bacterial infections and are not the solution for infections caused by viruses such as common colds or flu. Despite their contribution to healthcare, antibiotics are currently recognized as the most misused drugs in the world with global overuse estimated at 40%-70%, mostly due to the ineffectiveness of current diagnostic solutions to distinguish between bacterial and viral infections. Antibiotics misuse often causes preventable adverse events that impact patient care and lead to the emergence of antibiotic-resistant bacteria, one of the major threats to global health today. To address these challenges, MeMed has been developing the ImmunoDx™, a novel technology that relies on the best available detection system for differentiating between viruses and bacteria - the body's own immune system. The ImmunoDx™ technology employs a simple blood test that provides the physician, within two-hours, the information he needs to decide whether to treat the patient with antibiotics or not. This technology has been tested on over 1000 patients of different ages and diseases and was found to be highly accurate and safe. The current study is a non-interventional study and the participants do not receive any investigational drug nor any experimental examination or procedure. Therefore, the collected data in this study will not affect the diagnosis, prognosis, or treatment of the participants. Participation includes the collection of a teaspoon of blood and collection of a specimen using a nasal swab. These procedures are common in the clinical practice and are widely performed and possess no significant risk. By participating in the study, the subjects impact the development of the ImmunoDx™ technology, which is expected to enable a future faster and more accurate diagnosis of infectious diseases as well as more appropriate prescription of antibiotics. This will open the way to improve treatment decisions in millions of patients around the world.
