Filter by:Prebiotics as bovine colostrum are considered as a valuable supplement in the prevention of upper respiratory tract infections, gastrointestinal tract infections and neonatal sepsis. It contains many bioactive substances, such as immunoglobulins, lactoferrin, lysozyme, lactoperoxidase, and other growth factors.There is a lack of research on the use of prebiotics for prophylaxis against recurrent urinary tract infection (UTI) in children.In this era of increasing bacterial resistance to antimicrobial therapy, bovine colostrum can offer an approach for prophylaxis against UTI in these patients.We aim at this trial to evaluate the efficacy and safety of bovine colostrum as a prebiotic for prophylaxis against recurrent urinary tract infection in children.
The goal of this prospective, interventional, single-center study is to assess whether the early detection of Influenza with smartwatch algorithms and alerting, rapid testing, and subsequent Baloxavir treatment demonstrate better post-infection outcomes versus publicly available- and Centers for Disease Control (CDC)-derived national statistics for equivalent household populations as well as pediatric kidney, heart, liver, lung transplant recipients and waitlisted patients.
The increase in activity within medical biology laboratories linked to the arrival of new markers (in cardiology, oncology, infectious diseases, etc.) and the acceleration of technical progress have created a prominent place for automated systems and their reagent kits within these establishments. It is in this context that CerbaXpert took the initiative to set up this research project for the collection of prospective biological samples and their analysis. It transcribes both a process of continuous improvement but also scientific development, making it possible to provide new and/or complementary data in order to improve the operation of automated systems and their reagents within medical biology laboratories. These data obtained in current practice via this study will also be compared with the technical information provided by the manufacturers of the reagents and their automatic devices.
The goal of this observational study is to facilitate standardized nontuberculous mycobacteria (NTM) outbreak investigations in healthcare centers. The main questions it aims to answer are: - Are respiratory NTM isolates identified as having membership in a suspected healthcare outbreak highly related based on whole genome sequencing? - Does epidemiologic investigation support healthcare-associated patient-to-patient NTM transmission? - Does healthcare environmental sampling support healthcare-associated NTM acquisition? If healthcare-associated NTM outbreaks are suspected, participants identified as having membership in a cluster of highly-related NTM infections will complete a demographic questionnaire.
The characterization of the bacterial or viral etiology of an infectious event is required for both isolation decisions and rationale use of antibiotics. In emergency room (ER), the direct identification of the causal pathogen is rarely available in real-time. Alternative is the identification of the host-response to either a bacterial or viral infection. One of this host-response is the expression of peripheral leukocytes cell surface markers, measured by flow cytometry. Investigators and others have reported the high diagnostic performances of combination of cell surface biomarkers to differentiate bacterial from viral infection. The CYTOBACT study aims to confirm on a 500 patients multicentric cohort (200 having already been collected during another study: SEPTIMET), the best combinations for this diagnostic issue. The study will be conducted in 3 emergency departments of APHP hospitals network in Paris, France. Patients with a suspicion of infection will be proposed to participate. No intervention will be introduced during the routine care in the (ER) which will be let at the discretion of the treating emergency physician. During the routine blood sampling in the ER, an additional 30 ml volume of whole blood will be collected, centrifugated, aliquoted and stored at -80°C for further measurement of the expression of a panel of cell surface markers. The participants will be followed up during their hospitalization (if any) and no longer than 28 days. Clinical data at admission, usual blood tests and all microbiological investigations performed during the hospital stay will be recorded into an electronic case record form (eCRF). Based on all those recorded data (excepted the results of flow cytometry for cell surface biomarkers) 2 independent adjudicators will qualify the infectious episode into bacterial,viral or no infection, and (if any) into infection, sepsis or septic shock (according to Sepsis 3.0 definitions). Using different "machine learning" statistical tools, all the combination of the cell surface biomarkers will be tested to select those with the highest performance to differentiate bacterial from viral infection.
The goal of this observational study is to investigate the effects of measles virus (MeV) infection on pre-existing immunity, vaccine response, and susceptibility to subsequent illness in children aged 1-15 either with or without acute MeV infection.
The objectives of this study are to analyze the oral microbiome modulations occurring during the transition from partial (with some residual teeth) to full edentulous (without remaining teeth) status and implant placement in subjects affected by severe periodontitis; to evaluate if microbiome changes in relation to the used of different implant material/surface; and to assess the variance of the changes to determine the sample size for future longitudinal prospective studies.
Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.
pleural infection remains a common medical problem with significant mortality and morbidity despite a better undrstanding of the aetiology , pathophysiology and recent advances in management approaches . the cornerstones of the managment op pleural infection include early identification of cases and accurate diagnosis . suitable antibiotic therapy , nutrition managment , efficient drainage of infected collection via chest tube with or without adjunctive therapies including intrapleural agents and ultimately surgical managment .
Malaria is a major public health problem. There were around 240 million cases of malaria and 627,000 deaths worldwide in 2020. Most of the deaths are in children under five living in Africa. It is a major problem for those who live in affected areas and for travellers. There is a great need for a safe, effective malaria vaccine. This study is being done to evaluate an experimental malaria vaccine for its safety and also look at the body's immune response to the vaccine. The vaccine tested in this study is called and "RH5.1". This is given with an adjuvant called "Matrix-M". This is a substance to improve the body's response to a vaccination. The aim is to use the vaccines and adjuvant to help the body make an immune response against parts of the malaria parasite. This study will assess: 1. The safety of the vaccines in healthy participants. 2. The response of the human immune system to the vaccines. This will be achieved by giving participants three doses of the RH5.1 vaccines at two different dose levels (10 micrograms and 50 micrograms). One group will have 3 doses of 10 micrograms given at 0, 1 and 6 months whilst the other will receive 2 doses of 50 micrograms (at 1 and 2 months) followed by a 10 microgram dose at 6 months- known as a 'delayed fractional dose'. Blood tests and information about any symptoms will be performed/collected that occur after vaccination. Information from previous studies suggests that a delayed fractional dose improves the immune response to the vaccine, particularly in terms of the antibody response. Current prediction is that this improvement is due to the delay in dosing, rather than the reduction in dose, and this study will help to answer that. Having a vaccine at a single dose is important for efficient production and dosing for vaccines rolled out in national programs so being able to move away from 'delayed fractional dose' regimens to 'delayed final dose' regimens will be important for vaccine development.
