Testing Spread and Implementation of Novel Methicillin Resistant Staphylococcal Aureus (MRSA)-Reducing...
Blood Stream InfectionsMRSA InfectionsThe purpose of this study is to implement strategies for improved efficiency and waste reduction ("Toyota Lean") and positive deviance, a social behavioral change process, utilizing frontline healthcare personnel to reduce infection bloodstream infection and MRSA infection in outpatient dialysis care. In two outpatient dialysis units, dialysis unit healthcare staff will be educated in Toyota lean techniques and conduct periodic "discovery and action" dialogues to identify and implement care process changes to reduce infection. Outcomes to be monitored will include incidence of bloodstream infections and MRSA infections of all types. Data will be assessed at quarterly intervals using interrupted time series analysis.
Bioimpedance Analysis in Septic Intensive Care Unit (ICU) Patients
SepsisPatients with severe infections initially require large amounts of fluid as part of resuscitation. Later on however, problems may arise from excess fluid such as increased time on a ventilator and kidney damage. The amount of fluid a patient has is difficult to assess. One approach is to determine the amount of fluid that is present in a large central vein. This can be done by physical examination of the jugular veins, or by placing a catheter within the vein. Unfortunately this method is unreliable and does not predict the amount of fluid a patient has. Bioimpedance analysis (BIA), is a device that can determine the amount of fluid in the body by measuring the body's electrical properties. It is a quick and painless test that assesses volume. The primary objective of this study is to determine if BIA measurements are associated with patient important outcomes such as time on a ventilator, risk of kidney failure requiring dialysis and death. We will also determine whether BIA is a measure of fluid status in ICU patients. This study will assess feasibility in establishing a multi-centre study assessing if BIA's role in predicting adverse outcomes and thereby prognosis and fluid status. We hypothesize that shorter vector lengths will be associated with hypervolemia and less ventilator free days.
SIRS and Bacterial Sepsis Discrimination by Biomarkers in ICU
SIRSSepsis2 moreAim of the study : The primary aim of the investigators study is to highlight the presence of biomarkers (biological indicators of the presence of inflammation or infection) of infectious processes during the systemic inflammatory response (SIRS) allowing, first to discriminate non-infectious inflammation from infectious processes and secondary to determine the microbial pathogen responsive of the infection. For this purpose the investigators will conduct a combinatorial approach of several blood markers including usual markers of inflammation and other blood and cells markers. Expression of small pieces of RNA (miRNA) known to inhibit determined gene expression, will also be analysed in monocytes (a specific group of white blood cells involved in the fist line of defences against microbes. Study design : For this purpose the investigators will include 300 patients admitted to the intensive care unit with suspicion of infection. Serial blood sample will be take for biological parameters analysis. Efficiency of each single parameters and of different combinations of different markers to determine the presence or absence of infection responsive of clinical inflammation will be studied.
The Influence of Oral Hygiene on Local Wound and Systemic Infection in Patients With Percutaneous...
DysphagiaPeristomal Wound InfectionPercutaneous endoscopic gastrostomy (PEG) is commonly used for long term enteral feeding of patients with severe dysphagia. The most common complication is peristomal wound infection. The possible mechanism the bacterial from the oral cavity disseminate during the PEG insertion through the stomach to the abdominal wall, in spite the routine use of antibiotic prophylaxis, have reported low rates of wound infection in patients who were already receiving antibiotics at the time of PEG Our hypothesis that washing the oral cavity with antibiotic solution prior the insertion PEG , We planned a prospective, randomised, double blind, one centre study of antibiotic mouth wash solution (0.2% Chlorhexidine gluconate) as.prophylaxis in PEG
Oxytocin Effects on Cytokines and Endocrine Parameters After LPS Induced Systemic Inflammatory Effects...
SepsisThe aim of this study is to determine if oxytocin administration is able to blunt LPS induced increase of cytokines (TNF-α) and if there is a change in the endocrine response after lipopolysaccharide administration in humans.
Prevention of Infection in Indian Neonates - Phase I Observational Study
SepsisIndia, with one of the world's largest populations, continues to struggle with extremely high infant and neonatal mortality rates. Neonatal infection (sepsis) now accounts for 50 percent of deaths among community-born (and 20 percent of mortality among hospital-born) infants. This study is the first phase of a multi-phase project investigating interventions to prevent neonatal infection in India.
A Simple Clinical Tool to Help Assess Patient Volume (Fluid) Status
SepsisPatients may have actual or relative intravascular volume depletion in a number of different disease states, particularly with sepsis syndrome. However, it is clinically difficult to determine volume status without invasive monitoring, which may cause unintended complications. Our hypothesis is that we can accurately estimate central venous pressure, which is a surrogate marker of volume status, with a noninvasive portable ultrasound device.
Prolonged Cardiopulmonary Bypass Time as Predictive Factor for in Hospital Infection
Bloodstream Infection (BSI)This study is to analyse the demographics and microbiological factors concerning patients undergoing cardio surgical intervention using CPB complicated with bloodstream infection (BSI) postoperatively.
Monitoring of the Mitochondrial Function of Circulating Myeloid Cells in Patients Hospitalized in...
SepticaemiaSevere infections (sepsis) are a common cause of admission to the intensive care unit. They represent a significant health risk for patients in the short and medium term. They are particularly linked to a change in the function of immune cells. In some patients, a state of pseudo-dormancy of monocyte and macrophage-type immune cells, called immunosuppression of myeloid cells, is observed. This situation leads to a worsening of the infection, so it should be avoided because it represents a danger for the patient even when they ar receiving antibiotics. At present, these events are still very poorly understood. Research is essential to understand how this state of immunosuppression of myeloid cells is established in order to adapt existing treatments or find new ones. Laboratory studies on animal models of septicaemia have shown that this state of immunosuppression of myeloid cells is closely linked to a change in the production of energy by myeloid cells (monocytes and macrophages). The functioning of the mitochondria ("energy factory" of the cells) in these cells is impaired. Thus, restoring mitochondrial function in myeloid cells could be a therapeutic solution against the immunosuppression of myeloid cells during severe septicaemia. The objective of this study is to verify whether alterations in mitochondrial function in myeloid cells also occur in patients with bacterial infection compared to patients without bacterial infection.
Objective Sepsis Identification Tool to Study Sepsis Epidemiology
SepsisGlobally, sepsis affects an estimated 31.5 million people and accounts for 5.3 million deaths each year. This calculation is based on data from western high income countries only. The purpose of this study is to develop an objective sepsis identification tool using electronic health records to study the epidemiology of sepsis in Hong Kong.
