Filter by:Ventilator-associated pneumonia (VAP) is the most frequent life-threatening nosocomial infection in the ICU. Oropharyngeal colonization with bacterial pathogens is the first step toward lung infection. Oral hygiene with Chlorhexidine mouth wash (CMW) is among the most widespread preventive measure to prevent VAP. Precise microbial documentation of CMW efficacy on oropharyngeal colonization is lacking. Investigators wish to determine CMW antimicrobial efficacy in ICU ventilated patients and to measure chlorhexidine residual concentration in patients' saliva at the same time-points after CMW.
In the present proposal, we hypothesize that specifically targeting pneumonia events with preventive interventions in the French EHPAD (Etablissements d'Hébergement pour Personnes Agées Dépendantes) setting (thus, improving the health status and quality of life of patients) may simultaneously produce relevant reductions in the healthcare costs. In fact, although the number of pneumonia cases may be numerically limited, the consequences of each event are potentially catastrophic for both the patient and the healthcare system. Unfortunately, to date, information about the incidence and economical effects of pneumonia in the older population living in the French EHPAD are extremely scare. To adequately evaluate whether there is room to implement preventive interventions aimed at reducing the onset of pneumonia in a cost-effective fashion on a large scale, preliminary data from this specific population are needed. This first step is crucial towards the appropriate design and conduction of possible future large-scale intervention trials in the EHPAD setting.
Diagnosis of pneumonia remains difficult in intensive care unit (ICU), notably after cardiac surgery. Lung ultrasonography (LUS) has been successfully used for diagnosis of pneumonia, but its usefulness and reliability was never evaluated after cardiac surgery. This study investigates the clinical relevance of LUS for pneumonia diagnoses in cardiac ICU.
Pneumonia is a major cause of illness in young children. The investigators are developing and testing a new thermometer like device called Multimometer, to measure the respiration rate (RR), temperature, heart rate (HR) and the degree of blood oxygenation (SpO2) of children who may suffer from pneumonia. These are called vital signs and their measurements greatly help to diagnose pneumonia. In the first part of the study, and in order to optimize and better align the size of the device with the face, the investigators will measure the average size and dimensions of young children's face. In the second part of the study, the investigators will compare the vital signs measurements with measurements obtained by other commonly used devices in ill children who are suspected to suffer from pneumonia.
In patients with clinical symptoms of respiratory infection, rapid identification of cases requiring antibiotic therapy is crucial to avoid development of multiple resistant bacteria. Identification of local acute-phase reactants can help assess the host's response to bacterial infection at the injury site. Here, the investigators developed an affordable, stable, feasible, and accurate diagnostic tool based on a locally produced protein with specific binding affinity to polysaccharides. The investigators further evaluated the ability of the novel test strip to rule out pneumonia.
Retrospective cohort analysis of children hospitalized for pneumonia comparing disease severity on admission, clinical course, treatment and outcomes and prospective telephone based Follow-Up assessement.
The study consists of two arms (PHARM and PEER) designed to educate participants about three vaccine-preventable diseases (zoster, pneumonia, and influenza) and vaccination. PHARM will consist of a 60-minute presentation about the three vaccine-preventable diseases and their vaccinations delivered by a pharmacist, featuring a didactic lecture and discussion supplemented by video clips of community members discussing their experiences around vaccination, as well as physicians underscoring the importance of vaccination. PEER will consist of a 60-minute small-group session led by a peer educator which includes scripted roleplaying exercises designed to reinforce learnings pertaining to these three vaccine-preventable diseases and their vaccinations. The components of these interventions will be designed to address specific barriers to vaccination identified by literature search and our prior work in the area of community-based vaccine education. Both arms will focus primarily on pneumococcal disease and zoster but will include limited content on influenza because participants are likely to have questions about how the flu and its vaccination differ from pneumococcal diseases and zoster. The study will be implemented in an older, predominantly African-American (AA) population, consistent with our prior work in this area.
The overall aim of the TREND study is to improve the differential diagnosis of bacterial and viral etiology in children below 5 years of age with clinical community acquired pneumonia. Specific objectives: - To assess the diagnostic accuracy of MxA for viral CAP (sub-study I) - To study etiologies in children with CAP (sub-study II) - To evaluate sensitivity and specificity for MariPOC® Respi test versus PCR for detection of respiratory viruses (sub-study III) - To assess sensitivity and specificity for a novel RPA-based point-of-care test versus PCR for detection of respiratory viruses (sub-study IV) - To assess long-term complications in children with CAP (sub-study V The study takes place at Sachs' Children and Youth hospital in Stockholm.
Pulmonary bacterial infections such as exacerbations of chronic bronchitis, nosocomial and community-acquired pneumonia represent a major public health issue. Antibiotics have shown their efficacy by direct antimicrobial activity and their limit particularly in case of multidrug-resistant microorganisms or in treating patients with aggravating pathologies. Innate immunity could be an alternative or complementary therapeutic pathway. Innate immunity receptors bind universal and invariant microbial molecular patterns present in bacteria, virus, fungus or parasite. Toll-like Receptors (TLR) activation by microbial agonist stimulates the innate immunity response which results in the production of chemokines, cytokines, antimicrobial molecules and the recruitment of innate cells. The " Pulmonary Infection and Innate Immunity " team of the Immunity and Infection Center in Lille (Group of Dr. Sirard and Carnoy) has a long expertise in the study of TLR5 and its agonist, the flagellin, a structural protein of bacterial flagella. TLR5 is expressed on the cell surface of macrophages, monocytes, dendritic and epithelial cells. Several studies in mice have shown the flagellin prophylactic potential during bacterial infections through a TLR5 dependent stimulation of innate immunity. Recently, the group of Dr. Sirard and Carnoy has shown that flagellin can be used in association with antibiotics to treat Streptococcus pneumoniae respiratory infections in mice. The results demonstrate that an agonist of TLR can increase the therapeutic index of an antibiotic and improve the pulmonary anti-infectious reaction. This innovative approach allows us to consider new antibacterial strategies where antibiotics have reached their limit (nosocomial infection, multidrug-resistant bacteria…). TLR agonists can activate multiple human cell type. Indeed, blood cells activation by TLR agonists have been recently characterized in healthy volunteers. However, there is no available data on the ability of TLR agonists to activate cells from patients with infectious pneumopathies. A study in these patients is inevitable if one is to consider the therapeutic use of agonists in respiratory pathologies.
This was a retrospective study that all teicoplanin-treated adult patients with Gram-positive infections admitted to Zhengzhou Central Hospital affiliated to Zhengzhou University from February 2015 to August 2016.
