Active clinical trials for "Communicable Diseases"

Take AS04 adjuvanted HPV16/18 vaccine as an example to evaluate the impact of HPV vaccination on HPV infection and related disease burden in the real world based on prospective cohort and Yinzhou Regional Health Information Platform (YRHIP), in order to bridge the gap in relevant evidence in China.

Joint replacement is a valuable surgical intervention that improves quality of life, provides pain relief, and restores function of patients. However, some patients need revision surgery due to failure of the implant, with periprosthetic joint infection (PJI) remaining a rare but serious complication following total hip (THA) and knee (TKA) arthroplasty. Diagnosing PJI is a major challenge as no diagnostic test with absolute accuracy exists. The diagnosis is based on a combination of clinical findings, laboratory results from peripheral blood and synovial fluid, microbiological culture, histological evaluation of periprosthetic tissue, and intraoperative findings. However, the preoperative diagnosis can be inconclusive and operative criteria are required for the definitive diagnosis. Therefore, novel diagnosing tools for identification of PJI are necessary. A recent study using a gene reporter assay, identified biomarkers in synovial fluid that define joint states in patients with osteoarthritis.However, no previous studies have investigated cellular signaling in synovial fluid of patients with PJI. With this study we want to explore the potential of a reporter gene assay of synovial fluid in patients with PJI and without PJI of their TKA and THA. Also, flow cytometry analysis of biological fluids has recently received increased attention as a potentially valuable method in diagnosing infections. For example, the method is already used to analyze urine samples for urinary tract infections. Recently, researchers have now also used this method to screen for the presence of bacteria. The most important limitation of flow cytometry analysis of synovial fluids for bacteria to date is that it is unclear as to which bacteria count value - the cutoff value - represent patients with PJI and which represent patients without PJI. With this study we want to explore the potential of flow cytometry analysis of synovial fluid in categorizing patients with PJI and without PJI. Our primary objective is to explore the value of synovial fluid analysis using a reporter gene assay and flow cytometry in the detection of a periprosthetic joint infection.

In this study, we will try to answer the following questions: What are the salient features of the microbiota in chronic anal fissure? Are these features associated with prognosis and response to therapy? Does an anal fissure swab and anal fissure tissue give comparable bacteriological results?

BK virus (BKV) infection has a major negative impact on transplant recipients. No BKV-specific antiviral therapy is available, so there is an urgent need to develop new anti-BKV preventive and therapeutic strategies.

To Demonstrate Clinical Performance of the TriQuik Invitro Diagnostic Device

The purpose of this study is to determine the success rate of two treatments for infection after total hip replacement: single stage arthroplasty exchange (your surgeon will take out your original implants and replace them with a complete new set) compared to irrigation and debridement with modular exchange (your surgeon will clean your implants with a surgical solution and take out the plastic liner and replace it with a new one - the rest of your hip implants will stay in place). The goal is to see if one is better than the other for the treatment of hip infection after a total hip replacement. A successful treatment means that you did not have to have another surgery on your hip for an infection-related reason.

The purpose of this study is to establish whether cranberry capsules reduce rates of urinary tract infections during initial rehabilitation immediately after spinal cord injury.

The objective of the project is to find out whether cleansing the vagina before a cesarean delivery decreases the risk of complications and infections after having the baby. If this is the case, cleansing the vagina before cesarean delivery can help improve outcomes for many women and make their early postpartum recovery much more pleasant, giving a healthier start for the family.

The goal of this observational study is to describe the immune signature of acute pulmonary infection.The main questions it aims to answer are: Nasal mucosal immune response in patients with influenza infection Difference of immune response between Viral sepsis and Bacterial sepsis Immunological differences between Viral sepsis and Viral pneumonia

This study aims to evaluate the diagnostic and prognostic performance of a novel mRNA diagnostic/prognostic classifier (interprets the expression of 29 host response mRNA biomarkers) from whole blood in adult patients presenting to emergency departments (ED) with suspected infection.
