Active clinical trials for "Communicable Diseases"

Pneumonia and diarrhea are the most frequent causes of infectious diseases in children under 5 years of age worldwide, responsible for 1.5 million deaths annually. In up to 80% of pneumonia cases the etiology is viral. Some viruses can persist up to 6 months after an acute infection. The time when viruses enter the body and whether they are commensals or only cause disease and are eliminated after an acute infection is unknown. Modern techniques have identified diverse communities of microbiota in healthy and sick people, and viral communities associated in a close interaction. The acquisition and colonization by respiratory viruses and the role in health and disease in this niche that is the microbiome is unknown. The role of probiotics in the prevention of respiratory disease and in the maintenance of homeostasis in the microbiota is poorly understood, and even more the probable relationship between the microbiota, the respiratory viruses that could be commensals or pathogens at the respiratory level, the time when children can be colonized, and their regulation with the administration of probiotics. The aims of the study are to determine the changes in the intestinal and respiratory microbiota, the viruses that can be commensals or cause disease and the role of probiotics in the prevention of respiratory diseases during the first year of life. A prospective, randomized, controlled clinical trial will be carried out making basic metagenomics studies (translational medicine). After informed consent, 120 newborns will be randomized into 2 groups, one will receive probiotics 4 times a week orally and the other a placebo consisting of sterile water 4 times a week. The clinical follow up will be done every 2 months until 1 year old, nasal washes and stool samples will be collected to determine the intestinal and respiratory microbiome. Multiplex polymerase chain reaction studies will be conducted to detect the presence of respiratory viruses and the time when the children acquire viruses that are commensal or only in the case of respiratory infection. The mothers will be asked to come for consult in case of respiratory infection and a nasal wash and stool sample will be taken. Descriptive, bivariate and multivariate statistics will be used to determine the associations between the microbiota, the viral metagenomics, the respiratory viruses and the risk of presenting or not respiratory infection in the group receiving probiotics compared to placebo.

This study is specifically designed to provide observational data which can be used to help in the design of future randomized clinical trials on both therapeutics and diagnostics for MDRO infections. To this end, clinical and epidemiological data will be collected on patients who have MDRO isolated from clinical cultures during hospitalization, as well as descriptions of the outcomes of patients treated with various antimicrobial regimens. Molecular and microbiological characterization will also be performed on MDRO isolates. These data will include a detailed clinical and epidemiological description of patients including identifying potential barriers to enrollment in future trials. In addition, data will be collected on species, strain type, and mechanism of drug resistance of the causative organism. Knowing the molecular characteristics will further inform future trial design as not all diagnostics detect and not all therapeutics are active against the same mechanisms of resistance.

This is a prospective cohort study. All patients presenting for periprosthetic joint infection and requiring debridement only or resection arthroplasty will be eligible. The synovial joint fluid will be sampled before the arthrotomy at the operation room. The purpose of this study will be to evaluate that 1) the concordance of organism identification by the direct identification of MALTI-TOF MS versus routine identification of MALTI-TOF MS and conventional cultures and 2) the timing of preliminary strain identification by the direct identification of MALTI-TOF MS, routine identification of MALTI-TOF MS and conventional cultures in patients with periprosthetic joint infection.

Cephamycin related to 2nd generation cephalosporins, the use of cefoxitin has long been limited to antibiotic prophylaxis. Because of its spectrum (sensitive staphylococci, enterobacteria including ESBL, streptococci, anaerobes), its stability and its low cost, it could be useful in curative bone and joint infections, especially in case of infection polymicrobial disease in patients for whom antibiotic alternative per os is limited.

Percutaneous endoscopic gastrostomy (PEG) was created to replace surgical gastrostomy in patients who are needed long-term tube feeding. PEG has less severe complication rate or mortality rate compared with traditional surgical gastrostomy. However, there are still some mild complications which cannot be completely prevented and peristomal infection is the most common one. Povidone-iodine (PVP-I) exhibits broad range of microbicidal activity via increasing the solubility of iodine. In our study, the gastrostomy feeding tube will be coated with a layer of Betadine before PEG technique. Investigators expect gastrostomy feeding tube coated with Betadine will reduce the oropharyngeal, esophageal and gastric bacteria colonization rate, followed by reducing peristomal infection rate.

Events occurring in the early stages of life play an important role in the development of chronic diseases; diet and lifestyle during pregnancy are recognized to be crucial determinants in modulating offspring microbiota, throughout a vertical transfer of dysbiotic maternal ambient. Moreover, the intestinal colonization is maximized in the first two years of life through newborn's type and time of feeding. This study will provide the starting point for a future prospective observational study to assessing the association between maternal lifestyle with infant microbiota and their influence future health.

Investigators plan to perform a review of medical records a single urology department to identify patients with febrile perioperative infection who underwent radical cystectomy and urinary diversion for bladder cancer from January 2014 to July 2017. Investigators plan assess a potential variables to find correlation with infections after surgery. Characteristics, including age, sex, length of hospital stay, body mass index (BMI), diabetes, hypertension, estimated glomerular filtration rate (eGFR), preoperative hydronephrosis, smoking status, neoadjuvant chemotherapy, pathological stage, lymph node involvement, types of urinary diversion, operative method (open/laparoscopic), operative time and receipt of a perioperative blood transfusion (PBT) will be asses as potential risk factor for perioperative infection.

This study evaluates antibiotic serum concentrations in correlation with perioperative fluid balance. Patients will be recruited in rectum and esophageal surgery (representative for low blood loss and restrictive fluid management) and in liver surgery (representative for high blood loss and liberal fluid management). The hypothesis is that high blood loss and liberal fluid management dilute antibiotic serum concentrations thereby potentially increasing surgical site infections.

This is a prospective surveillance study to estimate excess deaths due to and risk factors associated with antibiotic-resistant infection among patients with hospital-acquired infection (HAI) in a resource-limited setting. We will focus on six pathogenic bacteria that are of clinically important in the hospital.

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
