Active clinical trials for "Communicable Diseases"

Factors associated with severe forms of COVID-19 infection in patients with inflammatory rheumatic diseases (IRD) or Autoimmune Diseases (AID) are unknown. This unprecedented situation leads to empirical and potentially erroneous advice and recommendations for care. Identifying factors associated with severity, in the context of this pandemic, which is expected to last many months, and possibly years, is crucial for future patients. The objective of this work is to identify the factors associated with the occurrence of severe forms of COVID-19 infection in patients with IRD or AID, by combining analysis of 2 large databases.

This study aims to examine the factors associated with preterm infant's intestinal microbiota depending on feeding type (breast milk or preterm formula)

To design and understand the mechanism of action of different combinations of nutraceuticals coupling bacteria, fibers and polyphenols, which can act on the 4 pillars simultaneously via an innovative ex-vivo model approach coupled with functional and quantitative metagenomics.

Intracranial infection is one of the common clinical complications after neurosurgery, especially after external cerebrospinal fluid drainage. Postoperative intracranial infection has a very high incidence, and its incidence is about 0.34%-3.1%. Once infection occurs, it will directly affect the length of hospitalization, mortality and disability of postoperative patients. The pathogenic bacteria of postoperative intracranial infections include G-bacteria and G+ bacteria, and fungi. Common G+ bacteria are Staphylococcus aureus. Common G-bacteria are Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa Bacteria, Escherichia coli and so on. In recent years, studies have reported that postoperative intracranial infections of G-bacteria are gradually increasing. In the previous study of our research group, it was found that Acinetobacter baumannii and Klebsiella pneumoniae accounted for the top two pathogens of postoperative intracranial infections in ICU. In particular, the proportion of carbapenem-resistant G-bacteria has increased, which brings difficulty and challenge to the treatment and seriously affects the prognosis of patients. Different pathogen infections may lead to different prognosis of patients with intracranial infection after neurosurgery. With different pathogens as the starting point, there are few studies comparing the clinical features, risk factors, and prognosis of intracranial infections after neurosurgery. Therefore, it is great significant to explore and understand different pathogenic bacteria, risk factors, drug resistance, treatment options, and prognosis after neurosurgery.

The present study focuses on patients with Pseudomonas aeruginosa (PSA) sepsis. The aim of the present study is to find out whether the M1 (pro-inflammatory) or M2 (anti-inflammatory) phenotype predominates in blood monocytes in critically ill patients with PSA-sepsis, and whether the severity of sepsis and outcome is associated with distinct monocyte phenotype and function.

The purpose of this study is to investigate the incidence of liver injury by statins in coronary heart disease (CHD) patients with history of hepatitis B virus (HBV) infection.

The purpose of the study is to compare different approaches for the treatment of prosthetic joint revisions and to optimize the outcomes in patients with prosthetic joint infections (PJI) by improving the treatment concept of PJI.

This study is a prospective, single center, observational, cohort study of patients to determine whether the Mologic Biomarker Panel can identify patients with infection from those without, including those with other reasons for inflammation (e.g. post-operative). It will also assess whether it has the potential to judge the severity of illness, prognosticate outcome and guide antibiotic therapy. The aim is to recruit patients who are "representative" of patients with suspected sepsis, uncomplicated infection, or non-infection related critical illness that require critical care intervention and assessment. This study is observational and will not alter patient management or the standard of care. The results from the investigational Mologic Biomarker Panel and associated research assays will not be provided to treating clinicians, or used in any manner to affect patient care. The study will take place over approximately an 18-month period and it is anticipated that approximately 600 patients will be collectively enrolled. The study aims to recruit patients from three environments within UCLH: The Emergency Department. Critical Care Unit Patients undergoing major surgery

This non-interventional study aims to determine whether there is a correlation between the Fc receptor polymorphism (FcR) and the course of the disease following HIV infection.

The objective of this study is to document the residual burden of acute upper respiratory infections (AURIs), acute lower respiratory infections (ALRIs), otitis media (OMs) and auditory functional and anatomical abnormalities in children under the age of 5 years in Nunavik who will be exposed to PHiD-CV in combination with PCV-7 or PCV-13. The comparison groups will be the cohorts of children who received no PCV vaccine (those born in 1994-1996) and those exposed to PCV-7 exclusively (those born in 2003-2007).
