Filter by:This prospective study evaluates the role of negative pressure wound therapy or wound VAC as a dressing over the incision to prevent poststernotomy wound infection in high risk patients.
Chronic exposure to (cigarette smoke) CS causes biological changes, including airway remodeling and changes in baseline gene expression profiles at the level of the epithelium. Our own data indicate that chronic exposure to CS suppresses the ability of epithelial cells to enhance antiviral gene expression in response to influenza infection and activate host defense responses. While there is a large body of evidence supporting the notion that exposure to CS causes significant changes in host defense responses, which may be linked to permanent changes in epithelial cells at the genomic level, it is not known whether new and emerging tobacco products have similar or distinct effects. Using live attenuated influenza virus (LAIV) inoculation in human volunteers, this study will compare influenza-induced responses in non-smokers (NS), cigarette smokers (CS), e-cigarette smokers (EC), hookah smokers (HS), and Little Cigar smokers (LCS) in vivo. This will be done by analyzing nasal viral titers, antiviral defense responses, inflammatory mediator production, and markers of immune responses for LAIV-induced responses between the different groups of volunteers.
- Lower limb amputations are performed usually as a last resort in patients with acute and chronic limb ischaemia (CLI) caused by vascular disease, poorly controlled diabetes or, infection. - In the period 2003-2008 there were approximately 5,000 amputations per year in the UK. - The Centre for Disease Control defines a Surgical Site Infection (SSI) as an infection within 30 days of an operation or up to one year if an implant is left in place and the infection is related to an operative procedure. - Figures from the Surgical Site Infection Surveillance reported that the highest rate of surgical site infection was reported in association with lower limb amputation at 13.1%. - There is a clear under-representation and the infection rate within our institution is approximately 25% which reflects the infection rate reported in a recent trial by Sadat et al (22.5%) - Prevention of surgical site infections is of paramount importance to patients, healthcare providers and policy-makers, as they impact on morbidity and mortality and have significant time and cost implications. - Currently there is NO CONSENSUS as to what the best practice is towards antibiotic administration in such patients. From a questionnaire-based audit we performed including vascular departments across the entire country, practice varies in both course duration (single dose → 5 days antibiotic course) as well as choice of antibiotics. - The guideline at our institution suggests the 5-day course of antibiotic prophylaxis. The course duration varies depending on the clinical picture as well as microbiology results and recommendations. - There are no randomised control trials that have investigated this aspect of patient care. We have set up one such trial and through it, we are looking to establish a standard practice which will hopefully be as beneficial as possible to the patient but also cost-effective for NHS.
The main objective of the study is to characterize the virulence factors of SGA and identify immunological and / or genetic factors predisposing to infections in children hospitalized with invasive GAS infection.
The study patients are patients suffering from primary or secondary immunodeficiencies investigated in the Hospital Necker for a suspected infectious disease. The study purpose is to assess the performance of a High Throughput Sequencing method, the PATHOQUEST method (from sample preparation to bio informatic analysis), versus the classic diagnostic approach. The study will evaluate the capacity of the PATHOQUEST method to detect pathogens responsible for an infectious disease episode and will also evaluate the delay of obtention of results compared to the classic diagnostic approach.
This study aims to assess how large an additional disease burden and what extra costs are generated by antibiotic resistance in patients suffering from infections caused by gram-negative bacteria, such as Escherichia coli and Pseudomonas aeruginosa, in hospitals in the Netherlands.
Peritoneal infection is still a frequent complication in peritoneal dialysis patients . In France, It contributes to the technique failure, responsible for about 20% of cases of transfer in hemodialysis. The risk of direct mortality is estimated at 1 to 6% according to studies. Peritoneal infection is involved in the dysfunction of the peritoneal membrane. Based on the recommendations of the International Society for Peritoneal Dialysis, the intraperitoneal route is preferentially recommended. For many antibiotics, pharmacokinetics (intravenous and intraperitoneal) was studied and protocols for IP administration were validated. Daptomycin, is a cyclic lipopeptide natural, active only on Gram-positive bacteria. It is presented as an alternative to vancomycin in infections resistant pathogens. The stability of daptomycin in peritoneal dialysis fluids (PDF) has been tested, and antimicrobial activity as well. Seven patients were treated with daptomycin intraperitoneally successfully. But no study has reported pharmacokinetics of daptomycin via the IP route. We propose a pharmacokinetic study of daptomycin administered intraperitoneally in 12 patients on CAPD and with Gram-positive peritoneal infection.
Lactoferrin is a protein that is a component of the immune system. It has many properties that could make it the ideal agent for the prevention of hospital-acquired infections. Lactoferrin has antibacterial properties (is able to kill or stop the growth of disease causing bacteria and fungal organisms), it improves immune function, and can increase the growth of beneficial bacteria in the bowel. Lactoferrin has been approved by Health Canada as a Natural Health product and is sold in health food stores as a supplement. However, given the potential beneficial effects of Lactoferrin, it requires further study as to its effects in acutely and seriously ill patients. One potential use which has not been studied is for the prevention of infections in critically adult ill patients. The aim of this study is to determine the utility of Lactoferrin in this patient population. The Lactoferrin that the investigators will be using in this study is extracted from cow's milk, where it naturally occurs. Cow lactoferrin has similar properties as that normally produced in the human body. This study is being conducted to determine how well a solution of Lactoferrin given orally and through a feeding tube helps to prevent infections and inflammation in critically ill patients in addition to usual care and other measures that are known to be partially effective for the prevention of infections.
The main purpose of this study is evaluate whether it is safe or not to use various combination of antibiotics (ampicillin, metronidazole, clindamycin, piperacillin-tazobactam, gentamicin) in treating infants with complicated intra-abdominal infections
This study will investigate the treatment of urinary tract infection in men. Specifically, the investigators are looking to see if shorter duration of antibiotics (7 days) is any worse than longer duration of antibiotics (14 days). The investigators will also study whether longer treatment leads to an increase in antibiotic resistant bacteria in the large intestine (colon), or an increase in drug side effects.
