Active clinical trials for "Communicable Diseases"

Postoperative infections are a common complication. A relationship between perioperative severe hyperglycemia and postoperative infections has been found in patients undergoing craniotomy. The aim of this study is to evaluate the epidemiology of intraoperative severe hyperglycemia (BGC >180 mg/dL; 10 mmol/L) and postoperative infections (wound, urinary and prosthetic joint infection) and to investigate if severe intraoperative hyperglycemia is associated with an higher risk of early postoperative (within the 7th postoperative days) infections (wound, urinary and prosthetic joint infection).

Catheter related infections (CRIs) were found to be associated with several risk factors, including patient related risk factors such as age, gender, clinical status and catheter related risk factors such as the vascular access location, dwelling time, catheter type and number of lumens. In addition to the inserted solution type and the experience of the professional who performs the procedure ,These factors constitute important strategic points for actions to compare the infectious complications of peripheral versus central venous catheters in critically ill patients.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records.

Correlation of Microbiome to Chronic Urinary Tract Infections (UTI) via Relative Abundance Found in Microbiome Sequencing

IL-2 is a pleiotropic cytokine which can regulate or stimulate the differentiation and function of CD4+, CD8+ and NK cells. An opened-labelled trial and a retrospective study have indicated the incidence of infection is lower in the treatment of low-dose IL-2 combined with corticosteroid and immunosuppressor. We are going to conduct a multi-center prospective observational study to verify the above results.

To quantify the diagnostic, prognostic and therapeutic value of spectrometric analysis of exhaled breath from hematological patients with respiratory infection.

This study aims to : Diagnosis of Systemic fungal infections in ICU patients. Detection the most common fungal species in ICU. Detection of in vitro antifungal sensitivity pattern

Acute myeloid leukemia (AML) patients are prone to blood stream infection (BSI) due to bone marrow suppression, oral and gastrointestinal mucositis, endovascular tubes, and the application of a large number of broad-spectrum antibiotics. The associated mortality rate is as high as 7.1 %-42%. The use of antibiotics within one hour after the first observation of hypotensive symptoms can guarantee a 79.9% survival rate. For every hour of delay, the patient's survival rate will drop by 7.6%. At present, the blood culture test cycle is long and the positive rate is low. Other infection-related indicators (PCT, CRP) or next-generation sequencing are not highly specific and easy to be misdiagnosed. X-ray, CT and other examinations only have a certain auxiliary value for the infected site. We need new diagnostic tools to accurately identify pathogens. Nano-seq is a next-generation sequencing technology for single-molecule, real-time sequencing and analysis. With ultra-long sequencing read length, it can quickly and accurately identify BSI pathogens types, and give appropriate drug sensitivity results based on drug resistance genes to meet the needs of 99.9% pathogen screening. At the same time, we hope to conduct a prospective evaluation to target high-risk groups of AML prone to BSI in the early stage. The intestine is the body's largest immune organ and the largest reservoir of microbial pathogens. The expansion of certain gut microbiota usually precedes BSI. If there is a correlation between the gut microbiota and MDR-BSI, the colonization and changes of the intestinal flora can be used to predict the risk of BSI in patients during treatment, and preventive measures such as early decolonization or biological intervention will reduce the risk of infection in the future. Combined with Nano-seq and various existing clinical pathogen detection technologies to reduce the occurrence and progress of clinical BSI.

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.

In this prospective longitudinal cohort the investigators reported the clinical, and biological characteristics of all critically ill patients admitted in the pediatric intensive care unit (PICU) of Bicêtre Hospital during the 2019 coronavirus disease (COVID-19) pandemics. Patients were older than 37 weeks of gestational age. No upper limit was set as the unit was transiently converted into a pediatric "adult COVID-19" intensive care unit.
