Nurse Promotion of IV to PO Antimicrobial Conversion
Behavior ChangeBacterial InfectionsThis is a prospective, quasi-experimental, historically controlled study to evaluate if a behavioural change intervention informed by the COM-B model of behaviour change can improve nurses' self-perceived capability, opportunity, and motivation to engage in the assessment of patients who may be appropriate for IV to PO antimicrobial conversion. This study also seeks to determine if this translates into an increase in IV to PO antimicrobial conversion rates in the acute care setting.
Impact of Specific Antimicrobials and MIC Values on the Outcome of Bloodstream Infections Due to...
Clinically Significant BacteremiaOrgan Transplantation7 moreMain objective: to observationally assess the efficacy and safety of different antimicrobials in BSI due to ESBL or carbapenemase-producing Enterobacterales in SOT. Secondary objectives: To evaluate the efficacy and safety of different antibiotics used for the treatment of infections caused by ESBL- and carbapenemase-producing Enterobacterales in the SOT population. To compare the efficacy of different antimicrobials between SOT and non-SOT patients (using matched controls from the "non-transplant" INCREMENT cohort). To create a microbiological collection of ESBL- and carbapenemase-producing Enterobacterales isolated from the SOT population. To provide data on specific MICs for each antimicrobial evaluated. To provide data on the prevalence of specific mechanisms of resistance and their clinical impact in the particular setting of SOT. To organise an international consortium capable of developing high quality prospective cohort studies and randomised clinical trials in the area of MDR and XDR Enterobacterales in SOT.
Procalcitonin (PCT) as a Diagnostic Marker of Bacterial Infection in the Patients Admitted for Fever...
Systemic Inflammatory Response SyndromeFeverLevels of PCT (a marker of bacterial infection) are highest during sepsis: in fact, PCT is normally produced by the C cells in the thyroid gland. PCT was initially studied by Assicot1 for distinguishing between bacterial meningitis and viral meningitis. The CALC-I gene codes for PCT. In the absence of infection, the extrathyroid mRNA expression of the CALC-I gene is repressed, and expression is restricted to neuroendocrine thyroid and pulmonary cells. Infection induces the ubiquitous expression of the CALC-I gene. PCT is not transformed into calcitonin in parenchymatous tissues. In a context of sepsis, the whole body acts as a neuroendocrine gland. Sepsis upregulates PCT mRNA expression much more than that of other cytokines. PCT is used in critical care departments as a diagnostic marker, a guide to treatment (antibiotics are withdrawn if the level falls) and a prognostic marker. There are few data on the diagnostic use of PCT in an internal medicine department. The available studies yielded contradictory results and only one prospective study has been performed . The objective was to study PCT in non-infectious, inflammatory pathologies and to establish whether PCT could distinguish infections from other inflammatory pathologies in patients in an internal medicine department. In a ROC curve analysis, a PCT threshold of 0.35 µmol/l gave the greatest specificity (88%) and sensitivity (72%). Other studies have been performed but featured small sample sizes and a retrospective design. Of the various studies performed in internal medicine departments, none included patients presenting with a suspected bacterial infection (according to the clinician's interpretation) and lacking information on their bacterial status. In fact, these diagnoses are a core component of hospitalisation in internal medicine departments for fever or inflammatory syndrome. The investigators intend to include all patients, including those lacking information on their microbiological status).
Study of Accuracy of New Diagnostic Technology to Guide Rapid Antibiotic Treatment for Serious Infections...
INFECTIONSSkin and Subcutaneous Tissue Bacterial Infections2 moreThis research will test a new ultra-rapid technology (called ID/AST Accelerate system) that uses a digital microscope to identify bacteria based on their growth patterns. This method does not have to wait for bacteria to grow in a lab. The new method can identify the type of bacteria within 2 hours of receiving a specimen. The new method also shows the effect of selected antibiotics on the bacteria including multidrug resistant bacteria so that doctors know within 6 hours from specimen collection which antibiotic kills the bacteria. To check the accuracy, speed and impact of the new method on antibiotic prescribing, investigators are proposing a study with two parts; The first part will test the accuracy and speed of the results obtained by the new method. The second part will test if having the results from the new method early would change the antibiotics prescribed to a patient in a simulation experiment. An independent infectious disease physician will be shown the results from the new method and asked if the results were accurate, would it change the antibiotic treatment for the patient.
Exposure to NSAIDs (Non Steroidal Anti-Inflammatory Drugs) and Severity of Community-acquired Bacterial...
Bacterial InfectionNSAIDs are widely consumed, and some are currently available for self-medication with indications 'Pain and Fever' (Cavalié, National Agency for Drug Safety (ANSM), 2014) There is no recommendation to limit their use in bacterial infections except for chicken pox in children. To date, no study has highlighted the aggravating role of exposure to NSAIDs on bacterial infections in adults, based on the usual septic severity Levy's score (SSS), and mortality, but it delays adequate antibiotics (Legras, Critical Care, 2009) Community-acquired bacterial infections in adults exposed to NSAIDs are serious by their spread (multiple locations), and suppurative character requiring frequent use of invasive procedures such as surgery or drainage. The SSS does not reflect the seriousness of these infections. They are frequently associated with use of ibuprofen (63.4%), and self-medication practices (65.5%). The main hypothesis is that NSAIDs exposure is associated with a specific severity of community-acquired bacterial infection, marked by dissemination, suppurative complications or even invasive procedures requirement. Our objectives are also to: Describe what NSAID use terms are associated to the risk of serious bacterial infections: molecule, dosage, duration of exposure, access (prescription or self-medication), associated drugs. To determine what type (s) (s) of bacterial infection is worsened by exposure to NSAIDs. To determine if other risk factors contribute to severity of bacterial community acquired infection To describe hospital costs associated to such severity of bacterial infection
Pharmacokinetics of Caspofungin After One Dose in Patients With Liver Failure
Bacterial Infections and MycosesLiver DiseaseThe objective of this study is to conduct a population pharmacokinetic analysis of caspofungin in a population of patients with moderate and severe acute alcoholic hepatitis or liver disease with Child-Pugh score B and C in order to better characterize pharmacokinetic parameters in case of moderate and severe liver dysfunction.
Thermal Imaging to Diagnose and Monitor Suspected Bacterial Infections
InfectionsBacterial2 moreThe purpose of this study is to test the feasibility of using thermal images to diagnose bacterial pneumonia instead of a chest x-ray in the future. More specifically, the objectives of this study are: 1) to determine if thermal imaging, using a commercial thermal camera can detect areas of heat emitted from the chest in similar locations to where a chest X-ray shows focal consolidation consistent with bacterial pneumonia; 2) to evaluate whether changes in heat emitted from the chest changes over time if it is possible to obtain serial images of the chest.

Iron Homoeostasis in Inflammation
InflammationBacterial Infections and Mycoses3 moreThe purpose of this study is to survey iron storage levels and their prognostic consequences in the context of acute inflammation. The impact of iron substitution in inflammatory states is controversial. We hypothesize that iron substitution may influence outcome in patients in inflammatory states.
