Active clinical trials for "Infections"

The aim of the study was to determine the incidence and factors associated with double-J urinary stent infection.

ear swabs will be collected from 120 patients with established CSOM at the ear-nose-throat (ENT) outpatient clinic at the Ziv medical center, and 120 swabs will be taken from children with Otitis Media with Effusion (OME) undergoing elective tympanostomy tube insertion, serving as a control group. Ear swabs will be frozen at -80C until analysis.DNA will be purified from ear swabs, and amplified by PCR so that a barcoded 16S rRNA library from each subject will be generated. Using correlation analysis, we will compare between microbial compositions in chronic otorrhea patients vs. control groups.An additional ear swab will be collected from patients and cultured to test antibiotic resistance.

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.

Total joint replacement is considered one of the most successful surgical procedures in the field of orthopedics. Despite this achievement, prosthetic joint infections is still considered a severe complication often leading to catastrophic results and requiring repeated and extensive treatment. The incidence of PJI (a prosthetic joint infection) varies depending on the joint involved; the rate of arthroplasties becoming infected is as follows: 1.7% of primary and 3.2%of non-primary hip arthroplasties. The accurate diagnosis of prosthetic joint infection often involves the combination of multiple factors including symptoms, signs, synovial fluid cell count, serum inflammatory markers, and culture. The sensitivity of synovial fluid culture is only 85%, so a negative culture does not rule out infection. However, the specificity of synovial fluid culture is approximately 95%, and positive cultures often imply the presence of prosthetic joint infection. The synovial fluid alpha-defensin test is an immunoassay that was specifically developed to aid in the diagnosis of prosthetic joint infection . The sensitivity and the specificity of the alpha-defensin immunoassay test have been reported to be above 96%. Molecular diagnostic tests using polymerase chain reaction (PCR) are emerging as a tool for the diagnosis of infections and noninfectious conditions. The application of PCR techniques with primers derived from the highly conserved regions of the bacterial 16S rRNA gene has been useful in the detection of bacterial organisms. Use of broad-range 16S rRNA gene PCR as a tool for identification of bacteria is possible because the 16S rRNA gene is present in all bacteria . Aim of the work: .Determine sensitivity and specificity of alpha defensing and 16S rRNA gene in diagnosis of prosthetic joint infection. Detection of antibiotic sensitivity for different organisms isolated from synovial fluid

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.
