Filter by:Antimicrobials (drugs that kill or stop the growth of microorganisms including bacteria, thereby treating infections) commonly used to treat patients with infections are becoming less effective over time as bacteria develop resistance to them. Antimicrobial usage itself can lead to development and spread of antimicrobial resistance. Antimicrobial resistance is now a major threat to patient safety. To conserve the effectiveness of antimicrobials the investigator need to develop ways to use them more sensibly healthcare professionals who diagnose and treat infections must be able to access antimicrobial guidelines and test results at the patient bedside. This needs to be provided rapidly and with support to make sure that the decisions on prescribing antimicrobials are the best that can be made.
The purpose of this study is to evaluate the safety and immunogenicity of AGS-v PLUS, a universal mosquito-borne disease and mosquito control vaccine, in healthy volunteers.
This is an epidemiological, retrospective and observational study, by reviewing clinical histories, of children hospitalized for influenza virus infection, their comorbidities and the treatments that have been performed
Part 1 is a randomized, double-blind, placebo-controlled study. It will assess the safety, tolerability, and pharmacokinetics of single and multiple orally administered doses of EDP-514 in healthy adult subjects. Part 2 is randomized, double -blind, placebo-controlled study including subjects with Hepatitis B Virus. It will assess the safety, tolerability, pharmacokinetics and antiviral activity of 28 Days of orally administered doses of EDP-514 in nucleos(t)ide reverse transcriptase inhibitor (NUC)-Suppressed Patients with Chronic Hepatitis B Virus Infection
This study will evaluate the safety, tolerability and pharmacokinetics (PK) of 6 once-monthly doses of oral islatravir (60 mg and 120 mg) compared with placebo in adults at low risk of HIV-1 infection
The emerging crisis of multidrug-resistant bacteria is accelerated by a massive overuse and misuse of antibiotics. It has been estimated that 50% of antibiotic prescriptions are inappropriate. Antibiotic interventions to improve prescribing patterns have been successfully implemented in primary care in Sweden and other countries. However, much of the last-resort antibiotics are used in hospitals in which decisions on therapy for bacterial infections are more complex. In this project we will explore the appropriateness of antibiotic prescribing in a hospital setting and measures to improve the quality of antimicrobial therapy. Antimicrobial stewardship interventions will be conducted at selected hospital departments using prospective audit and feedback in a multifaceted and cross-disciplinary approach. The intervention effects on antibiotic consumption, appropriateness of prescriptions, patient outcome and emergence of resistance will be evaluated, and a financial cost-effectiveness analysis will be performed.
Clinical pneumonia is a leading cause of pediatric hospitalization. The etiology is generally bacterial or viral. Prompt and optimal treatment of pneumonia is critical to reduce mortality. However, adequate pneumonia management is hampered by: a) the lack of a diagnostic tool that can be used at point-of-care (POC) and promptly and accurately allow the diagnosis of bacterial disease and b) lack of a prognostic POC test to help triage children in need of intensive assistance. Antibiotic therapy is frequently overprescribed as a result of suspected bacterial infections resulting in development of antibiotic resistance. Conversely, in malaria-endemic areas, antibiotics may also be "underprescribed" and children with bacterial pneumonia sent home without antibiotic therapy, when the clinical pneumonia is mistakenly attributed to a co-existing malaria infection. The investigators previously identified combinations of protein with 96% sensitivity and 86% specificity for detecting bacterial disease in Mozambican children with clinical pneumonia. The investigators' prior work showed that it is possible to identify biosignatures for diagnosis and prognosis using few proteins. Recently, other authors also identified different accurate biosignatures (e.g., IP-10, TRAIL and CRP). In this study, the investigators propose to validate and improve upon previous biosignatures by testing prior combinations and seeking novel combinations of markers in 900 pediatric inpatients aged 2 months to 5 years with clinical pneumonia in The Gambia. The investigators will also use alternative case criteria and seek diagnostic and prognostic combination of markers. This study will be conducted in Basse, rural Gambia, in two hospitals associated with the Medical Research Council Unity The Gambia (MRCG). Approximately 900 pediatric patients with clinical pneumonia aged 2 months to 5 years of age will be enrolled. Patients will undergo standard of care test and will have blood proteins measured through Luminex®-based immunoassays. Results of this study may ultimately support future development of an accurate point-of-care test for bacterial disease to guide clinicians in choices of treatment and to assist in the prioritization of intensive care in resource-limited settings.
HIV patients are likely to suffer from opportunistic infections, in absence of highly active retroviral therapy. This happens due to lack of awareness of HIV status among patients or unresponsive to anti retroviral drugs. This study is for the prevalence of AIDS defining OIs among treatment naive HIV patients.
Effective combination antiretroviral therapy (cART) has resulted in a dramatic reduction in AIDS mortality. Over the last decade, the proportion of deaths caused by liver-related etiologies, including co-infection with hepatitis C (HCV) and hepatitis B (HBV) viruses, alcohol abuse, and fatty liver, has increased between 8 to 10 fold in the post-cART era while AIDS-related mortality has fallen more than 90-fold. HIV infection without viral hepatitis is also at risk for liver disease. Indeed, HIV mono-infected persons experience common conditions, such as obesity, diabetes and dyslipidemia, which are risk factors for non-alcoholic fatty liver disease (NAFLD). NAFLD is the most common liver disease in Canada. It is a fatty infiltration of the liver that is not evolutive per se, but it is the first histopathological step for non-alcoholic steatohepatitis (NASH), a progressive disease characterized by much inflammation leading to liver fibrosis and cirrhosis. NASH may be frequent in the setting of HIV mono-infection due to excess of metabolic risk factors, long-term cART, HIV itself and lipodystrophy. An early diagnosis of NASH is essential to establish a prognosis and initiate interventions to reduce progression of liver disease towards cirrhosis. Early diagnosis of NASH is critical for targeting metabolic and hepatologic interventions, which can impact on progression to cirrhosis and end-stage complications. Non-invasive tools for liver fibrosis and NASH, including Fibroscan/CAP and CK-18, are accurate and ideal for screening and serial monitoring. No study has specifically targeted the non-invasive diagnosis of NASH in HIV mono-infected patients. There has been no study about the use of CK-18 as a biomarker for NASH in the setting of HIV mono-infection. Furthermore, CAP has never been applied to this specific population. Finally, there is no data about the potential beneficial therapeutic effect of vitamin E on NASH associated to HIV infection. The investigators hypothesize that CK-18 and Fibroscan/CAP can be used as non-invasive tests to diagnose NASH in HIV mono-infected persons. Likewise, the investigators hypothesize that there will be a significant prevalence of NASH diagnosed by non-invasive tools among patients with HIV mono-infection. The investigators further hypothesize that a 6 months treatment trial with vitamin E supplementation will improve non-invasive diagnostic tests, and/or the metabolic and hepatic profile in HIV mono-infected patients with a non-invasive diagnosis of NASH.
Foods in the human diet can affect the development of diseases over time, such as diabetes or heart disease. This is because the amount and types of foods in the diet eat can affect a person's weight, and because different foods are metabolised (processed) by the body in different ways. Scientists have also found that the bacteria in the human gut (the gut microbiome) affect their metabolism, weight and health and that, together with a person's diet and metabolism, could be used to predict appetite and how meals affect the levels of sugar (glucose) and fats (lipids) found in blood after eating. If blood sugar and fat are too high too often for too long, there is a greater chance of developing diseases such as diabetes and cardiovascular disease. The gut microbiome is different in different people. Only 10-20% of the types of bacteria found in the human gut are found in everyone. This might mean that the best diet to prevent disease needs matching to a person's gut microbiome and it might be possible to find personalised foods or diets that will help reduce the chance of developing chronic disease as well as metabolic syndrome. The study investigators are recruiting volunteers aged 18-70 years to take part in a study that aims to answer the questions above. Participants will be asked to consume standardised meals on up to 8 days while wearing glucose monitors (Abbott Freestyle Libre) to measure their blood sugar levels. Participants will also be required to prick their fingers at regular intervals to collect small amounts of blood, and to record their appetite, food, physical activity and sleep using apps and wearable devices. They will be asked to collect a fecal and saliva sample before consuming the standardised meals, and to provide a fasted blood sample at the end of the study period.
