The Clinical Character,Risk and Prognosis of Post-neurosurgical Intracranial Infection With Different...
Intracranial InfectionsVentriculitis4 moreIntracranial 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.
Monocyte Profiles in Critically Ill Patients With Pseudomonas Aeruginosa Sepsis
Pseudomonas InfectionsPseudomonas Septicemia8 moreThe 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.
Calprotectin for Rapid Diagnostic Infection Spontaneous of Ascites
Rapid Diagnosis of Spontaneous Infection of Ascitic FluidThe prognosis of spontaneous bacterial peritonitis (ISLA) remains a serious complication of cirrhosis. Rapid diagnosis of ISLA is a key issue for improving the prognosis. The determination of calprotectin in ascites, used for the diagnosis of infection of ascitic liquid, could allow the diagnosis in a very short time (about 30 minutes). To date, the determination of calprotectin in ascites was not evaluated properly. The investigators would thus evaluate the interest of the determination of calprotectin in ascites for the rapid diagnosis of ISLA in cirrhotic patients, like you, hospitalized for decompensation of their disease. The main purpose of this pilot study will determine the optimal threshold calprotectin in ascites for diagnosis of ISLA.

Importance of Patient Selection for Treatment of Infected Total Knee Prosthesis
Knee InfectionThe infection of a total knee replacement often imposes changing implants. The change in two step is currently considered the gold standard. The change in one step is a much debated attitude: strictly contra-indicated for some professionals, but others agree to reserve these for favorable suspected cases selected. Several criteria have been proposed in the literature: age, condition, duration of infection, known bacterium responsible, not virulent and sensitive to antibiotics, no fistula, no significant bone destruction. But these criteria are poorly validated, standing over an experience of surgical teams rather than high-level scientific studies. Some authors have proposed to achieve change in one step systematically. The results of these cohorts on healing the infection does not seem very different from the changes in two steps. But it is most often single-center series, uncontrolled, with small numbers.

Prosthesis-related InfectionsThe 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.
The Performance of the Mologic Biomarker Panel in Infection
SepsisInfectionThis 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
