Filter by:The foods we eat - our diet - can affect whether we develop diseases during our lives, such as diabetes or heart disease. This is because the amount and types of foods we eat can affect our weight, and because different foods are metabolised (processed) by the body in different ways. Scientists have also found that the bacteria in our guts (the gut microbiome) affects our metabolism, weight and health and that, together with a person's diet and metabolism, could be used to predict appetite and how meals affect levels of sugar (glucose) and fats (lipids) found in blood after eating. If blood sugar and fat are too high too often, there's a greater chance of developing diseases such as diabetes. The gut microbiome is different in different people. Only 10-20% of the types of bacteria found in our guts 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 years or over from the TwinsUK cohort to take part in a study that aims to answer the questions above. The participants will need to come in for a clinical visit where they will give blood, stool, saliva and urine samples. The participants will also be given a standardised breakfast and lunch and fitted with a glucose monitor (Abbott Freestyle Libre-CE marked) to monitor their blood sugar levels. After the visit, the participants will be asked to eat standardised meals at home for breakfast for a further 12 days. Participants will also be required to prick their fingers at regular intervals to collect small amounts of blood, and to record constantly their appetite, food, physical activity and sleep using apps and wearable devices.
The purpose of this study is to evaluate the effects of CSE-1034 (Ceftriaxone+ Sulbactam+ EDTA) compared to Meropenem for treating hospitalized patients with complicated urinary tract infections, including acute pyelonephritis caused by β-lactamase producing gram-negative bacteria
Immunoprophylaxis with two hepatitis B vaccinations following the hepatitis B immune globulin (HBIg) and hepatitis B vaccine at birth is largely effective in protecting infants from hepatitis B virus (HBV) infection. However, hepatitis B infection due to immunoprophylaxis failure often occurs in approximately 10% of infants who are born to highly viremic mothers with HBeAg-positive. Maternal HBV DNA > 200,000 IU/mL is the major independent risk for mother-to-child transmission (MTCT). A recent randomized controlled trial has shown that Tenofovir Disoproxil Fumarate (TDF) use during the third trimester of pregnancy could safely reduce the rate of MTCT with few adverse effects when combined with the administration of the standard immunoprophylaxis to the infants. However, HBIg is expensive and not available in many developing countries, resulting approximately 30% of infant infection when they received only HBV vaccination. The present study aims to investigate if highly viremic mothers who are treated with TDF from the second trimester to delivery in combination of infant's standard series of HBV vaccinations (omission of HBIg) have a comparable MTCT rates, when compared to those of mothers who receive TDF at the third trimester in combination of infant's standard HBV vaccinations and a birth dose of HBIg.
The purpose of this study is to evaluate whether virus-specific T cell lines (VSTs) are safe and can effectively control three viruses (EBV, CMV, and adenovirus) in patients who have had a stem cell transplant and also in patients that have a primary immunodeficiency disorder with no prior stem cell transplant.
Context: The hyperglycemia is an important independent risk factor for the Surgical Site Infection (SSI) development among liver transplantation recipients. Objective: To evaluate the effects of an intensive postoperative protocol of blood glucose management on the surgical site infection incidence among liver transplantation recipients. Material and methods: It is an open-label clinical trial that will be randomized into 2 groups of blood glucose (BG) control: patients will undergo BG control regular in the facility chosen to research development (BG targeted 130-180 mg/dL) and the second one will undergo intensive BG control (BG targeted 80 - 130 mg/dL) until patients are eating at least 50% of a full liquid diet or receiving bolus tube feedings. A computer program will be employed to generate the randomized schedule that will be put into sequentially numbered opaque sealed envelopes by an external expert to research. A finger prick device will be used to measure the blood glucose. A blinded adjudication committee to analyse the primary endpoint SSI will adopt the SSI criteria given by the Centers for Disease Control and Prevention. The research proposal will be registered on ClinicalTrials.gov database. Central tendency and dispersion measures, Pearson's χ2 test, Fisher's Exact Test, Mann-Whitney, Wilcoxon-Mann-Whitney and survival analysis by Kaplan-Meier estimated and Log-rank test will be used for data analyses. Expected outcomes: The results of the study should contribute to establishing better clinical practices on glycemic control in the liver transplantation recipient's postoperative period aiming to reduce SSI incidence and its associated morbidity and mortality.
Background: Currently prevalence of HPV infections for high risk strains among young women in Switzerland is unknown. In addition, since 2008 a vaccination program to prevent these infections has been implemented in a number of cantons, but its actual population impact is currently unknown. For now, HPV screening in Switzerland is mainly performed by gynecologists or during gynecological consultation at hospital. This method is certainly effective, but expensive; population coverage of screening is still insufficient. A whole segment of the target population does not participate in this screening especially young people of foreign origin, for various reasons: economic cost, no gynecological, and for other reasons. Several studies raise the effectiveness and efficiency of self-sampling to increase coverage of screening, and the rate of participation of non-participants. Through this study, the investigators evaluate effectiveness of this vaccination on the prevalence of HPV infections using HPV prevalence kit and assess evolution of infection and clearance of HPV virus during 5 years in a population of young unvaccinated and vaccinated women. Method: During the study, each participants will perform a vaginal swab sampling by auto to research HPV. These samples will be sent to a laboratory where HPV typing is done by PCR using the Anyplex ™ II technology. The study will focus on a sample of 400 young women. Participants must complete a questionnaire containing demographic questions and their HPV immunization status. Vaccination coverage expected in this population is about 50%. Depending on the state of vaccination, two different groups will be vaccinated vs unvaccinated (200 women per group). The cases of HPV infection are then calculated for each group and compared as a function of the status of vaccination. Statistical tests will be applied McNemar's test for comparison between the HPV prevalence rates between the 2 groups. Expected Results: This study will allow us to confirm the possibility of using self-sampling as a method of screening and monitoring of HPV infections in the general population, it will also enable us to document the effectiveness of HPV vaccination by comparing prevalence rate of HPV infections among a group of young girls vaccinated and not vaccine and assess evolution of infection and clearance of HPV virus.
The results found in the literature do not allow to define objectively the indications respective for a one-step or a two-step exchange of prosthetic joint. Some criteria could help to decide for one-step exchange or two-step exchange: bacteria is/are identified, profile of the bacteria, anesthetic difficulties,.. A puncture could allow to identify the bacteria involved in the prosthetic joint infection (PJI) and an antibiotherapy for a few days can be given to the patient in order to decrease the inoculum. Then, a one-step exchange can be performed. The purpose of this study is to describe the management of patients who had a pre-treatment before a one-step exchange of their prosthetic joint.
The purpose of this prospective randomized clinical trial is to compare two currently accepted standard-of-care treatment strategies: Medical thoracoscopy as compared to instillation of intrapleural tissue Plasminogen Activator (TPA) and human recombinant Deoxyribonuclease (DNase) for the management of empyema or complicated parapneumonic effusion (CPPE) in adults.
The primary objective of the study is to evaluate the antiviral effect and safety of inhaled ALX-0171 in adults diagnosed with respiratory syncytial virus (RSV) respiratory tract infection after hematopoietic stem cell transplantation (HSCT). The secondary objective is to assess the clinical activity, pharmacokinetics (PK), virology, and immunogenicity of inhaled ALX 0171 in adults diagnosed with RSV respiratory tract infection after HSCT.
