Active clinical trials for "Communicable Diseases"

In the present study we will compare bacteriological findings and the incidence of SSI in relation to laminar airflow (LAF) ventilated ORs, conventional (also called displacement or mixed) ventilated ORs and conventional ventilated ORs with the addition of tables equipped with units providing a local LAF over the surgical instruments. The hypothesis is that there exist a correlation between number and types of airborne bacteria and bacteria in the surgical wound and on surgical instruments at the time of wound closure.

To investigate the influence of antibiotics on the incidence of biliary tract infections after PTCD for malignant obstructive jaundice.

this prospective study we will examine the prevalence of fungal infection in patients undergoing oral cavity surgery without treatment with antifungal drug

PHENOTYPE is an investigator-led, observational cohort study which aims to explore the long-term outcomes of patients with COVID-19 infection and to identify potential risk factors and biomarkers that can prognosticate disease severity and trajectory.

The AGMT_COVID-19 Registry is designed as multicenter observational cohort of patients, that are tested positive for SARS-CoV-2. Data will be collected from all sites in Austria willing to participate. Due to the non-interventional nature of the AGMT_COVID-19 registry, only routine data, which has already been recorded in the patient's medical chart, is transferred to the eCRF.

7. Objectives To apply e-health methods to perform active monitoring and assess determinants of incident Infection of COVID-19 in a hospital population. 8. Study design Prospective, Single-centre, observational clinical study. 9. Disease or disorder under study Healthy people in risk of COVID-19 infection. 10. Main variable. Symptoms related to infection caused by SARS-Cov2. 11. Study population and total number of patients Men and women in general god health status aged between 18 and 80 years that currently are employees of Hospital de La Princesa . 12. Duration of treatment Each subject will be monitored, since its recruitment, for a period of 12 weeks. 13. Timetable and expected date of completion The overall duration of the study is estimated at about 6 months, from patient recruitment to the last data recorded by last subject. The aim is to carry out this study from March 2020 onwards.

There are lack of endoscopic criteria for diagnosing Helicobacter pylori (H. pylori) infection by conventional white light imaging (WLI). Linked color imaging (LCI) is a newly developed endoscopy technique, which can diagnose mucosal lesions and H. pylori infection by enhancing color contrast of the mucosa. The aim of the study is to investigate the ability of LCI for diagnosing H. pylori infection compared with WLI.

Understanding the emergence of linezolid-resistance in Staphylococci has been allowed in the past years through the discovery of the clonal dissemination of a chromosomal cassette carrying a modified crf gene. New mutations have even been described. Though, clinical evidences are still lacking, especially concerning the factors associated to this emergence. It could seriously become quite problematic to eliminate one of the last therapeutic weapon at our disposal for the treatment of severe or complicated infections caused by resistant strains of Staphylococci and Enterococci. We aim to describe the mechanisms that permitted to this resistance to become clinically significant, concerning meticillin-resistant Staphyloccocus epidermidis strains causing blood stream infections in ICU patients, and show the clinical risk factors associated with it through a case-control study on patients hospitalized in two ICUs of our hospital between 2011 and 2016.

Infections are common causes of morbidity and mortality in pediatric cancer patients. Today, there are limited data on the incidence, distribution of specific infections, causative agents and risk factors for severe infections in this population. Moreover, little data exist on the epidemiology of infections among pediatric patients with solid tumors. The objectives of the present study are to define the incidence, categories of infections by organ systems, etiologic agents and risk factors for infections in different pediatric malignancies. The results of this study will help the investigators to better understand the epidemiology of infections in the different types of pediatric malignancies, enable the investigators to identify high risk patients, and design a better approach to empiric treatment of these patients. A prospective, multi-center study, conducted in 5 pediatric hematology-oncology units across Israel (Rambam Medical Center, Haemek Medical Center, Schneider Children's Medical Center, Hadassah Medical Center, Soroka Medical Center). All children aged 0-18 years of age, newly diagnosed with cancer and admitted to day care or inpatient departments with fever of >38.0 C will be included in the study. Demographic, clinical and microbiological figures will be collected in each center by a research assistant supervised by the infectious disease specialist. Data will be collected according to a pre-defined Patient Data Form and entered into an electronic data base that will be analyzed accordingly. In each event of febrile episode during chemotherapy, the following data will be collected by a research assistant using a patient data form and computerized software: Demographic data: age, gender, ethnicity. Clinical data: Underlying disease, immunizations, prophylactic antibiotics, presence of central venous catheter, intensity of chemotherapy, duration of fever, duration and severity of neutropenia, diagnosis of present event. Imaging data Microbiological data Outcome The statistical analysis will be performed by an epidemiologist and statistician using the SPSS 12.0 software.

The purpose of this study is to study the prevalence of EBV, HCMV, HHV-6 in saliva and on the toothbrush patient with periodontitis.
