Filter by: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.
The purpose of this study is to learn more about infection by Clostridium difficile (also known as C. difficile). C. difficile is a common bacterium (a germ that may cause disease) that can live in the human gut. Some people have it without having any symptoms. In other people it can cause illness ranging from mild diarrhea to severe colitis (infection of the colon). C. difficile makes toxins that damage the cells that line the colon. The study doctors want to find out how these toxins cause damage to the cells in the colon.
A phase IV, prospective, multicenter , randomized open label, 48 weeks study to evaluate the antiretroviral efficacy and safety of atazanavir/ritonavir or darunavir/ritonavir, each in combination with a fixed dose of tenofovir disoproxil fumarate- emtricitabine in HIV-1-infected treatment-naïve subjects with CD4 counts below 200 µL.
The goal of this study is to present a large single-institution experience reporting surgical site infection rates in patients who have undergone intra-abdominal surgery followed by wound closure with Negative Pressure Wound Therapy. A retrospective review of patients' charts will be conducted to analyze surgical site infection rates between wound closure with and without Negative Pressure Wound Therapy (NPWT). American College of Surgeons National Quality Improvement Program data from previous standard of care (primary closure after colorectal surgery) will be used for comparison with newly adopted standard of care treatment regimen (wound closure with NPWT). Data on patients who underwent intra-abdominal surgery will be retrospectively collected and a database will be created. These individuals will be identified through medical records and recontacted by mail and/or phone to collect study data. Finally, patients newly referred to the Principal Investigator for intra-abdominal surgery will be enrolled in the database. After giving informed consent, data on surgical site infection rates and outcomes will be collected. Longitudinal outcomes will be assessed at 30 days, 6 months, and 12 months post-operatively. These patients' outcomes will be compared to a group of patients treated by the Principal Investigator who also underwent intra-abdominal surgery without Negative Pressure Wound Therapy. We hypothesize that fewer patients treated with negative pressure wound therapy following intra-abdominal surgery will develop surgical site infections than patients who had intra-abdominal surgery but were not treated with Negative Pressure Wound Therapy.
In this study, investigators are trying to see if infusion of "m-CTLs" will prevent or treat cytomegalovirus (CMV), Epstein Barr Virus (EBV) and adenovirus (AdV) reactivation or infection after cord blood transplant. Patients with blood cell cancer, other blood disease or a genetic disease may receive a cord blood transplant (UCBT) from an unrelated donor. After receiving a cord blood transplant, they are at risk of infections until a new immune system to fight infections grows from the cord blood cells. In this study, investigators are trying to give special cells from the cord blood called T cells. These cells will try to fight viruses that can cause infection. Investigators will test to see if blood cells from donor that have been grown in a special way, can prevent patients from getting an infection. EBV, AdV and CMV are viruses that can cause serious life-threatening infections in patients who have weak immune systems after transplant. T lymphocytes can kill viral cells but normally there are not enough of them to kill all the virus infected cells after transplant. Some researcher have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person during a viral infection after a bone marrow transplant. Some of these studies have shown a positive therapeutic effect in patients receiving the CTLs (specially trained T cells) after a viral infection in the post-transplant period. In this study we are trying to prevent or treat viral infections by given the CTLs soon after getting the umbilical cord blood transplant. With this study, investigators want to see if they can use a kind of white blood cell called T cells to prevent or treat AdV, EBV and CMV infection. Investigators will grow these T cells from the cord blood before transplant. These cells have been trained to attack adenovirus/EBV/CMV- infected cells and are called multivirus-specific cytotoxic (killer) T-cells or "m-CTL." Investigators would plan to give patients one dose of m-CTL any time from 30 to 364 days after your transplant. They have used T cells made in this way from the blood of donors to prevent infections in patients who are getting a bone marrow or blood stem cell transplant but this will be the first time investigators make them from cord blood.
The purpose of this study is to investigate whether there has been a change in the number of hospital admissions for respiratory tract infections among children following the July 2007 introduction of a ban on smoking in public places in England.
Many studies have showed that rapid point-of-care (POC) c-reactive protein (CRP) test can reduce inappropriate use of antibiotic at primary health care level. In Vietnam, prevalence of antibiotic abuse for community acute respiratory infection has been reported. This study will test the hypothesis that CRP POC testing for patients with non-severe acute respiratory illness at primary healthcare stations reduces inappropriate antibiotic use safely. The study will be conducted at ten district health care facilities in Hanoi, Viet Nam. Investigators intend to enroll 2,000 participants aged 6-65 years with non-severe acute respiratory infection. Patients will be randomly allocated to the control or the intervention arm. Participants in the control group will be treated according to routine care. Participants in the intervention arm will have a CRP test, the results of which will be available to the health care practitioner to contribute to their diagnosis and treatment decisions. All patients will be followed-up via telephone call after 14 days. The study will compare the proportion of patients in each arm receiving any antibiotics within 2 weeks of study enrollment.
This is an observational prospective study of an in-vitro diagnostic (IVD) assay planned to enroll 632 subjects. The study will be conducted in two stages: Stage A is aimed at identifying individual biomarkers and constructing a multi-parametric diagnostic model, whereas Stage B is aimed at testing the multi-parametric diagnostic model using a fresh cohort of patients. A collection of clinical, radiological and laboratory data will be gathered in order to establish a final diagnosis. Blood samples will be analyzed and the levels of approximately 700 and 250,000 biomarkers will be determined using immunoassays and molecular measurements respectively. A final diagnosis will be determined based on a majority decision of a panel of three or more independent physicians. Based on the final diagnosis, the accuracy of individual biomarkers and combined sets of biomarkers for differentiating between distinct groups of patients will be evaluated.
