Neutrophil CD64 for Early Diagnosis of Nosocomial Infection in Preterm Newborns
Nosocomial InfectionDiagnosis of late-onset sepsis is difficult in the absence of specific clinical signs and biological markers in the infection initial phase .The aim of this study is to determine the performance of a new infection marker : Neutrophil CD64 for early diagnosis in nosocomial infection (NI) in preterm newborns. METHODS : Monocentric prospective study including preterm newborn infants (<37 weeks of gestationnal age ) with clinical suspicion of nosocomial infection in a neonatal intensice care unit (Neonatal intensive care unit of Montpellier, France). Patients will be enrolled in the study after informed consents. Rapid and automated CD64 measurment will be realized during the conventional blood sample including C-Reactive Protein (CRP), Procalcitonin (PCT) and blood culture. Broad-spectrum antibiotic therapy can be started on the advice of clinician and blinded the result of CD64. Patients will be then classed in three groups using CDC criteria (center for disease control) : 1-no infection, 2-infection, 3-possible infection during the multidisciplinary staff. Specificity, sensitivity, negative and positive value of CD64 will be calculated and the performances of CRP, PCT and CD64 will be compared. 153 patients are needed in the study enrolled during a period of 12 months. PERSPECTIVES Neutrophil CD64 monitoring might be help clinicians to manage nosocomial infections in neonates.CD64 allow to integrate in a decision algorithm with the determination of the best cut-off value to faster processing nosocomial infections and could help to reduce unnecessary antibioc therapy. A rapid technique for determination of CD64 should be readily available in our unit.

Monitor adverse events (Adverse Event Following Immunization - AEFI) in vaccinated subjects and analyze the associations with: (a) demographic variables and anthropometric parameters (sex, age, BMI, etc.); (b) socioeconomic-cultural variables; (c) co-morbidities. Secondary objectives: Monitor the antibody response in vaccinated subjects and analyze the associations with: (a) demographic variables and anthropometric parameters (sex, age, BMI, etc.); (b) socioeconomic-cultural variables; (c) co-morbidities. Assess the quantity (antibody titer) and quality of the anti-Spike immune response induced by vaccination. Evaluate the dynamics of the infection and the protective efficacy of the vaccine against infection / disease by studying the incidence and titre of antibodies against Nucleoprotein (N) induced by natural infection; Evaluate the neutralizing capacity of sera vs. a panel of sera selected and analyzed in house and in in vitro microneutralization systems with live virus; To evaluate the cell-mediated immune response (CMI) to vaccination against SARS-CoV-2 in a subgroup of vaccinees. Methodology: Administration at baseline of a questionnaire for the collection of clinical data. Perform a blood sample to measure antibody response in vaccinated subjects Administer a questionnaire to evaluate adverse events after vaccination Reassess the antibody response 1 month after complete vaccination and 6 and 12 months after the start of vaccination An antibody assay will be drawn in a subgroup before subjecting the subject to the vaccine. In a subgroup, the blood collected will also be collected in a heparinized tube for the study of cell-mediated immunity. In the event that a subject participating in the study presents during the course of the observation the positivity for the molecular research of SARS-CoV-2 RNA to the oro-nasopharyngeal swab, a new sample will be performed and sent to the Istituto Superiore di Sanità for the search for viral variants.
Evaluating Antibiotic Stewardship Assisted by Computer in the University Hospital of Nancy (MACABAO)...
AntibioticHealthcare Associated InfectionAntibiotic resistance is one of the most pressing health threats that mankind faces now and in the coming decades. Antibiotic resistance leads to longer hospital stays, higher medical costs and increased mortality. In order to tackle antibiotic resistance, a computerized-decision support system (CDSS) facilitating antibiotic stewardship and an electronic surveillance software (ESS) facilitating infection prevention and control activities will implement in our tertiary care university hospital. The investigators conduct a pragmatic, prospective, single-centre, before-after uncontrolled study with an interrupted time-series analysis 12 months before and 12 months after the introduction of the CDSS for antibiotic stewardship (APSS) and ESS for infection surveillance (ZINC). APSS and ZINC will assist respectively the antibiotic stewardship and the infection prevention and control teams of Nancy University Hospital (France). The investigators will evaluate the impact of the CDSS/ESS on the antibiotic use in adult (≥ 18 years) inpatients (hospitalised ≥ 48h). The primary outcome is the prescription rate by all healthcare professionals from the hospital of all systemic antibiotics expressed in defined daily doses/1 000 patients/month. Concurrently, the investigators will assess the safety of the intervention, its impact on the appropriateness of antibiotic prescriptions and on additional precautions (isolation precautions) as recommended in guidelines, and on bacterial epidemiology (multidrug-resistant bacteria and Clostridioides difficile infections) in the hospital. Finally, the investigators will evaluate the users' satisfaction and the cost of this intervention from the hospital perspective.
Impact of Daily Bathing With Chlorhexidine in the Critical Patient
Healthcare Associated InfectionsThe search for preventive measure with daily bathing with chlorhexidine in the critical care patient will result in a reduction in patient colonization with multidrug resistant pathogens. Thus, preventing healthcare associated infections. The aim of this study was to determine the impact of daily bathing with chlorhexidine in patient colonization, environment and healthcare workers in the medical intensive care unit (MICU). The study will be conducted at the University Hospital "Dr. José Eleuterio González", a 450-bed teaching hospital in Monterrey, northeast Mexico. This is a prospective, experimental, randomized, open-label, double blind study comparing chlorhexidine versus placebo. Any patient 18 years or older admitted to the MICU or with less than 48 hours of patient-days will be included. Patients who present burns with more than 20% body surface, pregnant patients and patients with allergy history to chlorhexidine. Samples will be obtained from the patient, patient environment and healthcare personnel. Sampling of the environment (bed rail, mechanical ventilator, table adjacent to the bed, etc.) and patient's anogenital and pharyngeal region will be collected with "swabbing" technique using cotton swabs and cultured according to Public Health England. Patient skin sampling will be obtained from anorectal region, pharynx, axillary and inguinal fold collected with Williamson-Kligman technique. Colonies will then be further selected and properly cultivated according to their characteristics. Antibiotic susceptibility, clonal relationship, biofilm index and antibiotic susceptibility to chlorhexidine will be determined. Demographics and clinical data will be collected from admission, throughout hospitalization and discharge.
Nosocomial Bacterial and Fungal Chest Infections in Cirrhotic Patients

The Global Prevalence of Infections in Urology Study
Hospital InfectionUrinary Tract InfectionsUrology departments from all over the world are invited to join the Global Prevalence Study on Infections in Urology (GPIU-study) and the GPIU Prostate Biopsy Side Study. The GPIU study is taking part annually in November since 2003. European urologists were the first group of specialist to register hospital acquired infections on an international level. More than 20.000 patients have been screened and more than 2000 patients are currently listed in this database. Why? Infectious complications after urological procedures, such as prostate biopsy and increasing antimicrobial resistance are posing significant threats to modern urology The GPIU-study is a combined quality improvement initiative and a scientific study. Once the participating departments have filled in the report forms they will get access to statistics showing the accumulated results for all participating hospitals. The participants can anonymously compare their own results with hospitals from all over the World. The GPIU-study application has been designed as an instrument to ongoing follow-up of the development of important factors related to infection on international, national and local levels.

NOSOcomial COVID-19 in ICU (NOSOCOVID)
Coronavirus Infectious Disease (COVID-19)Nosocomial Infection1 moreThe current global pandemic at COVID-19 is a major public health issue. Transmission of the virus is primarily through direct and close person-to-person contact. The protection of health care personnel and the limitation of transmission of nosocomial COVID is paramount. Protective measures have already shown their effectiveness in limiting the spread of the virus: the use of masks, the wearing of protective gowns, the wearing of protective eyewear, social and physical distancing. A recent U.S. study (Rhee et al. JAMA 2020) reported a very low incidence of 1.7% of nosocomial COVID, but this was achieved with the application of rigorous infection risk management protocols. In addition to the widespread use of masks and protective measures, dedicated COVID units had been created, with air treatment. The implementation of these dedicated units requires the mobilization of considerable human and material resources, which is not feasible in all hospitals over the long term. In view of the second wave of the epidemic in France, with the rising numbers of new cases of COVDI-19 admitted to intensive care units since the end of the summer 2020, it is essential to organize the intensive care units to ensure the protection of personnel and limit the risk of nosocomial COVID-19, while continuing to care for non-COVID patients. In Intensive Care unit (ICU) at the Nantes University Hospital, a strict protocol for the management of suspected or confirmed COVID patients has been in place since early september 2020. The objective of this study is to evaluate the effectiveness of this protocol for managing the infectious risk of SARS-COV-2 on the incidence of nosocomial COVID in patients admitted in ICU. The secondary objectives are to evaluate the incidence of nosocomial-associated COVIDs contracted by caregivers, and the incidence of asymptomatic positive SARS-CoV-2 cases in ICU.
Rapid Test for Detection of the Focus of Infection in Post Neurosurgical Patients.
InfectionBacterial5 moreBackground: Due to anatomical restrictions, the inflammatory response to intra-cerebral bacterial infections exposes swollen brain tissues to pressure and ischemia, resulting in life-threatening damage. However, diagnosing meningitis in patients after neurosurgery is complicated, due to brain tissue damage and changes in cerebrospinal fluid (CSF) caused by surgery. Hepatocyte growth factor (HGF) is a local, acute-phase protein. Previous studies on community-acquired septic meningitis reported high levels of intrathecal-produced HGF. Aim: The aim of present study is to evaluate a new platform for qualitative determination of HGF in body fluids and revealing the site of injury. Method: Based on a reverse-methachromacy method, strips are prepared. The surface on the strip changes colour to blue upon contact with HGF. Plan: CSF, urine and sputum of patients that develop fever post neurosurgery are analysed with the test and the results compared with conventional diagnostic methods. Clinical value: A rapid, equipment-free test gives the opportunity to identify the infectious focus in the infected organ long before culture results are available.
Cross Transmissions of Pseudomonas Aeruginosa Between Children From a Same Cystic Fibrosis Center....
Cystic FibrosisPseudomonas Aeruginosa1 moreCystic fibrosis is the most common hereditary autosomal recessive disease in the Caucasian population. The diseases is caused by a mutation of the gene coding for the CFTR protein (Cystic fibrosis transmembrane conductance regulator), an ion channel present at the apical pole of the epithelial cells. The channel dysfunction induces a deficit in hydration and a hyperviscosity of different exocrine secretions. Clinically, Cystic fibrosis is a multi-systemic disease. Pulmonary and pancreatic involvement are classically in the foreground. Degradation of respiratory function, associated with acute and chronic infections, represents the major cause of morbidity and mortality. Pseudomonas aeruginosa is a ubiquitous gram-negative bacillus found primarily in stagnant water. Pseudomonas aeruginosa is capable of colonizing the digestive, pulmonary and urinary mucosa and the skin. This bacterium is incriminated in many opportunistic infections including respiratory infections in patients with cystic fibrosis. Pseudomonas aeruginosa infection is the most common parenchymal lung infection in the Cystic fibrosis community. Pseudomonas aeruginosa chronic carriage represents a factor of poor prognosis associated with an increase in morbidity and mortality. Complications related to chronic carriage of Pseudomonas aeruginosa justify the implementation of strategies of eviction, screening and eradication of acute Pseudomonas aeruginosa infection. In addition to Pseudomonas aeruginosa contamination of patients via the environment, hand and airborne infections between patients with Cystic fibrosis have been reported. Measures to eliminate cross-transmissions have therefore been implemented in a majority of hospitals. The aim of the study is firstly to identify the number of Pseudomonas aeruginosa cross-transmissions between patients with Cystic fibrosis followed-up in Cystic fibrosis center of HUDERF. Investigator will use the Pulsed-Field Gel Electrophoresis to assess the possibility of cross-infection. Depending on the results, Investigator will implement new strategies to avoid future cross-contamination in our different places of care (consultation, hospitalization, physiotherapy…).
