Filter by:In this study, we evaluate peri- and postoperative parameters of patients undergoing a cystectomy and try to find risk factors for infectious complications. In detail, we analyze their medical history, demographic data, lab values, microbiological tests as well as histological and radiological findings. Furthermore, after discharging our patients, we send them several follow-up questionnaires at regular intervals and offer them free follow-up examinations.
Hospital-acquired infections (HAI) have been shown to increase length of hospital stay and mortality. Infections acquired during a hospital stay have been shown to be preventable. The skin of patients is considered a major reservoir for pathogens associated with hospital-acquired infections, and has been suggested as a potential target for interventions to reduce bacterial burden and subsequent risk of infection. The use of daily Chlorhexidine (CHG) bathing in intensive care patients has been advocated to reduce many of the infections in critically ill patients. However, the effectiveness of CHG bathing to reduce ICU infections has varied considerably among published trials, making the effectiveness of CHG bathing in ICU patients uncertain.
Colistin is an antibiotic active against several classes of multi-resistant gram-negative bacteria; the drug should be used in high doses in patients on continuous renal replacement therapy, since the drug is eliminated through the dialysis filter. This is an Open-label, Phase 4, interventional, prospective, single-center pilot study aimed to analyze the concentrations of colistin in plasma and ultrafiltrate by liquid chromatography/mass spectrometry, in 20 critically ill patients admitted to intensive care and suffering from severe infections by multi-resistant bacteria, who receive continuous renal replacement therapy.
The scientific, feasible and effective mode of standardized cleaning and disinfection of ICU high-frequency contact surfaces is discussed and verified.
The investigators hypothesize that the use of a personal hand hygiene system (SafeHavenTM) by anesthesia providers in the adult operating room, combined with a novel infectious pathogen tracking system (OR PathTrac) will decrease participant exposure to pathologic bacteria in the adult operating room.
Primary objective: 1. 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: 1. 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. 2. Assess the quantity (antibody titer) and quality of the anti-Spike immune response induced by vaccination. 3. 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; 4. 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; 5. To evaluate the cell-mediated immune response (CMI) to vaccination against SARS-CoV-2 in a subgroup of vaccinees. Methodology: 1. Administration at baseline of a questionnaire for the collection of clinical data. 2. Perform a blood sample to measure antibody response in vaccinated subjects 3. Administer a questionnaire to evaluate adverse events after vaccination 4. Reassess the antibody response 1 month after complete vaccination and 6 and 12 months after the start of vaccination 5. An antibody assay will be drawn in a subgroup before subjecting the subject to the vaccine. 6. In a subgroup, the blood collected will also be collected in a heparinized tube for the study of cell-mediated immunity. 7. 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.
Aim: To investigate if host factors, such as composition and diversity of intestinal microbiota and/or genetic determinants, are associated with a higher risk of recurrence of Clostridioides difficile infection (CDI). To generate a predictive tool based on epidemiological, clinical, genetic and microbiologic variables aimed to identify patients at a higher risk of CDI recurrence in a context of optimized ICD management. Design: Multicenter prospective cohort study. Patients: Older than 18 years patients with CDI diagnosis, made by IDSA criteria, in the participant centers. Follow-up: A stewarship program aimed to improve CDI management, including early detection of CDI recurrence, will be implemented in the participant centers. Blood samples for genetic testing and stool samples for intestinal microbiome studies will be collected. Variables and data analysis: The primary outcome variable will be the emergence of CDI recurrence. Potential independent predictors of recurrence, including genetic and microbiological factors, will be assessed. A predictive tool based on independent predictors of recurrence will be built in a development subpopulation. The performance of the model will be assessed by ROC curves, and sensititvity, especificity, as well as negative and positive predictive values will be calculated, both in the development subpopulation and in a validation subset.
This research aims to study the properties of metallic nanoparticles"MNPs" (silver nanoparticles "AgNps" and copper nanoparticles "CuNps") on the 2 most common nosocomial bacteria which are highly resistant to antibiotics including Staphylococcus aureus and Pseudomonas aeruginosa, to evaluate the growth inhibiting properties of MNPs on all bacterial isolates, to evaluate the biofilm inhibitory effect on biofilm forming bacterial isolates and the synergistic effect of these MNPs in combination with antibiotics on the antibiotic resistant isolates.
The 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.
Brief summary : Very few studies have evaluated the prevalence of multi-drug resistant (MDR), highly resistant emerging bacteria and Clostridioides difficile toxinogenic (CDt) in residents and in healthcare workers (HCW) in nursing home (NH). Most of study were conducted in acute care services and were limited to specific bacterial species. Hypothesis : The carriage of MDR bacteria in resident may be a risk factor for an outbreak in NH or in healthcare facility. Primary outcome: The objective of this study is to estimate the prevalence for carriage of MDR bacteria and CDt in residents in NH. Secondary outcomes: - Estimate the prevalence for carriage of MDR bacteria and CDt toxigenic in HCW in NH. - Identify the risk factors for carriage of MDR bacteria and CDt in residents in nursing home - Identify the risk factors for carriage of MDR bacteria and CDt in healthcare workers in NH - Evaluate the presence of cross-transmission of MDR bacteria and CDt in one or several NH - Evaluate the association between the presence of cross-transmission of MDR bacteria and CDt in a NH and the management of infection control - Establishment a collection of stool samples
