Filter by:The purpose of this study is to compare the safety and pharmacokinetics of ciprofloxacin after inhalation of single 52.5 and 48.75 mg doses in COPD patients. In this study the 48.75 mg dose will be administered for the first time using a new high dose strength (i.e. one capsule containing 75 mg powder = 48.75 mg ciprofloxacin) formulation. Safety investigations will focus on local tolerability in the lung and evaluate whether the patient can inhale the higher amount of powder compared to the lower dose strength. Pharmacokinetics is to see how the body absorbs, distributes, breaks down and gets rid of the study drug. Results from this study will be used to decide whether the new dose strength is suitable for larger clinical trials planned for the COPD patients population.
This study aims to prospectively estimate the incidence of Respiratory virus (RV) infections in children with symptoms of an upper respiratory tract infection (URTI) or lower respiratory tract infection (LRTI) at St. Jude Children's Research Hospital (SJCRH) using the FilmArrayTM System, a novel highly sensitive and rapid assay for RV detection. An aliquot from the leftover sample remaining after clinical diagnostic testing will be used for FilmArrayTM analysis. Patients will be accrued on the study over a one year period.
It has been estimated that 90% of bloodstream infections associated with catheters, are due to CVCs, and that 500 to 4,000 patients in the United States die annually due to these bloodstream infections. The risk of central line associated bloodstream infections is typically expressed as the number of line infections per 1000 catheter days. This study's goal is to develop a uniform CL protocol, updated practice guidelines based on current evidence, and a standard procedural checklist based on CL care bundles recommended by the Institute for Healthcare Improvement. A secondary goal is to create a CL registry to capture and store data relevant to each CL placed throughout the institution. This registry will provide a wealth of data on CL insertions and complications that may be used as a valuable source of information for quality assurance, performance improvement, and research. With the knowledge and information obtained through this registry, educational offerings can be created, and a standardized institutional process for CL insertion can be developed.
An estimated 250,000 cases of central line-associated bloodstream infections occur in US hospitals annually, and an estimated 30,000 to 62,000 patients die as a result, the marginal cost of which to the health-care system is approximately $25,000 per episode. Inconsistent and outdated clinical practices have been identified as key causative factors. In order to improve overall healthcare delivery and outcomes, current and future healthcare professionals need to complement their clinical skills with systems-based skills. Specific to the problems of central lines, during a 2005 chart review of institutional patient safety issues, a LVHN internal quality committee found multiple cases involving the insertion of central lines, including cases involving arterial placement and malposition. The internal quality committee review revealed that newer residents were primarily involved in these cases. As a result of the committee's findings and review of the literature, a standardized Central Line Access and Placement course was designed as part of the incoming residents'orientation process. This study's goal was to contribute to the knowledge-base of health professional education and to build a sustainable model for one set of learning and development interventions, with the expectation that findings will have broad relevance for patient safety initiatives, health professional training and development programs, and healthcare delivery improvement.
Japanese encephalitis (JE) is one of important zoonotic infectious diseases in Taiwan. JE caused by Japanese encephalitis virus (JEV) which transmitted by Culex tritaeniorhynchus and used swine as amplifying host. Infections leading to overt encephalitis are estimated to be 1 in 1000 cases. Among JE confirmed cases, approximately 25 percent of cases die and 50 percent of the survivals develop permanent neurologic and/or psychiatric sequelae. JEV circulated in Taiwan are belonged to genotype III and the vaccine strain selected from same genotype. Genotype I JEV was first detected in northern Taiwan in 2008 by CDC, and the same genotype JEV were detected in mosquito collected in central Taiwan by our group. In order to study the genotypic shift of JEV in Taiwan areas, and the effects of the replacement of genotype on vaccine, we will conduct the JEV seroepidemiology in Hualien county which was the highest incidence of JEV in Taiwan. The aims of this study were: (1) study the circulating of genotype I JEV in Hualien county; (2) determine the virulence of genotype I JEV in human; (3) differential diagnosis of JEV genotype I or III infection among confirmed cases; (4) measure the cross neutralizing activity, after immunized with genotype III JEV vaccine, against genotype I JEV; (5) determine the age-specific seroprevalence of JEV antibody; (6) estimate the annual risk of infection for JEV.
In 2008, our ED administered an average of 245 doses of vancomycin per month. Currently there is no consistency in the ED practice in regards to vancomycin dosing. In 2009, the IDSA put forth new recommendations for vancomycin dosing in order to achieve therapeutic levels more rapidly. It has been hypothesized that if therapeutic levels are reached more rapidly then patients will in turn have better clinical outcomes and that the development of resistant organisms will be decreased. Methicillin resistant Staphylococcus aureus (MRSA) has emerged as one of the most deadly pathogens that are currently plaguing our patient population. Vancomycin is one of only a few antibiotics that are effective for treating MRSA. It is imperative that the ED physicians consistently and correctly dose vancomycin in order to give the patients the best chance to fight infection while helping to prevent further resistance in this already highly resistant organism. It is believed this study will reveal that the new dosing recommendations by the IDSA will lead to the achievement of therapeutic levels more rapidly. This information will in turn help to convince ED physicians that a change in current clinical practice is warranted and ultimately lead to better clinically outcomes for the patients.
PROJECT JUSTIFICATION: Cervical cancer is a serious public health problem in Brazil, and is the cause of significant morbidity and mortality among Brazilian women. In spite of government efforts to improve the coverage rates of Pap tests, the disease-related incidence and mortality rates remain high and the diagnosis is still too late.Considering that the chronic human papillomavirus (HPV) related genital infection leads to cervical cancer development, cervical cancer should be the target of primary prevention through vaccination. PROJECT OBJECTIVES: This project aims to evaluate de following vaccination indicators: 1) Program acceptance rate; 2) Vaccine coverage rate; 3) Three-dose completion rate; 4) Rescue vaccination demand; 5) Adverse event rate; TARGET POPULATION: Schoolgirls attending the 6th and 7th grades of elementary school (mean age = 11.9 yo). VACCINATION PROGRAM: The program adopted the quadrivalent vaccine because it is considered superior to the bivalent vaccine in preventing HPV-induced lesions. In addition to preventing the development of pre-cancer lesions and cervical cancer, the quadrivalent vaccine has also proved to be effective in preventing condyloma, and vaginal and vulvar cancer. The girls received the vaccines doses at their schools (school-based program) and also at the Barretos Cancer Hospital. RESULTS: Program acceptance rate = 91.8% (95%CI: 87.0%-96.8%); Vaccine coverage for 1st, 2nd and 3rd doses = 87.5% (95%CI: 82.9%-92.2%), 86.3% (95%CI: 81.8%-91.1%) and 85.0% (95%CI: 80.5%-89.7%). Three dose completion rate = 97.2% (95%CI: 92.0%-100.0%). Reasons for dropping out of the vaccination program included: moving out of town (17), lost during follow up (16), guardians' decision but without a reasonable justification (3), girl refused to continue in the program (1) and pregnancy (2). Two girls interrupted the vaccination because of adverse events reported by the parents. Rescue vaccination demand = 279 girls on the first dose (20.3%; 95%CI: 17.9%-22.8%), 357 on the second dose (26.3%; 95%CI=23.6%-29.1%) and 291 on the third dose (21.7%; 95%CI=19.3%-24.4%). Thirty adverse events were recorded or observed in 4,074 doses, providing an adverse event rate of 0.7% (95%CI: 0.5%-1.1%). There was no severe adverse event.
The working hypothesis is that the low HDL serum level predict favorable response to anti viral treatment in chronic HCV (genotype 1) viral infection. This might be used to improve the rate of sustained virologic response.
Fever is one of the most common problems in pediatrics. Differentiating between bacterial infections, that require antibiotic therapy, and viral infections that resolve on their own is an important challenge for physicians. C-reactive protein (CRP) is a protein that increases in response to inflammation and its level is generally higher in bacterial infections compared to viral infections. it can be measured by a simple blood test, however its utility as a sole marker for bacterial infection is limited. The hypothesis of the study is that measuring CRP velocity, e.g the value of CRP divided by the hours since the fever started will improve the utility of CRP for the diagnosis of bacterial infections in children.
The specific objectives of this investigation are to assess the effectiveness of daily gargling and vitamin D supplementation as preventative measures against incident upper respiratory tract infection (URTI) in students attending McMaster University. Investigators hypothesize that 1. Vitamin D3 supplementation will decrease the incidence of symptomatic upper respiratory tract infections in university students 2. Gargling will decrease the incidence of symptomatic upper respiratory tract infections in university students.
