Filter by:This study is designed to evaluate maternal virological and immunological parameters to determine their ability to predict congenital cytomegalovirus (CMV) infection. When a pregnant woman is infected with CMV, her immune system (which protects her from infection) is activated and the virus can be found in the woman's bodily fluids (blood, saliva, urine, vaginal secretions). The aim of this study is to find out if there is a link between either the pregnant woman's immune response or the presence of the virus in these bodily fluids and the child/foetus being infected with the virus.
This is a multi-center, comparative, two-arm, parallel-group, single-blind, phase III study to assess immunogenicity and safety of 4th LBVH0101 (Haemophilus influenzae type b tetanus toxoid conjugate vaccine) vaccination compared with 4th Hiberix™ vaccination after the same vaccination with primary one in healthy toddlers who completed the primary vaccination with LBVH0101 or Hiberix™ in LG-VHCL002 study.
Postoperative complications, especially bacterial infections, are relatively common and cause increased morbidity and mortality. Effective and timely antimicrobial treatment is important for prognosis, and delayed diagnosis and treatment substantially increase mortality. The early diagnosis of infection and sepsis are today based on diagnostic tests that have been available for years, like WBC count, SR and CRP. These markers suffer from several drawbacks; their sensitivity and specificity for infection and sepsis are not good enough and their kinetics are rather slow in terms of both increase and decrease. A major disadvantage of CRP is that after surgery and trauma this marker generally increases for several days, reaching a plateau typically on day 2-4 following the event, and therefore, in most cases do not offer the needed guidance for early treatment of bacterial infection. More recently, other biomarkers for infection and sepsis have become available, some of which appear acceptable for diagnostic use. Procalcitonin (PCT) and neutrophil CD64 are both promising new markers for the early detection of infection. They do both have their pros and cons compared to each other and compared to the traditional markers, such as CRP and WBC count. It is a general view that further research is needed before these markers will be accepted as part of the routine protocol for the diagnosis of infections, especially in relation to postoperative complications. The aim of the present study is to investigate the clinical utility of procalcitonin (PCT) and neutrophil CD64 as markers for infection and inflammation: - to evaluate if it is possible to detect early phase postoperative infections by using these tests versus traditional markers such as CRP, SR and WBC count (with differential). - to differentiate between systemic bacterial infection and systemic inflammation due to the surgical trauma. The hypothesis is that PCT and neutrophil CD64 are more sensitive and specific analysis for the early detection of infection after abdominal surgery than CRP (and other widely used tests for inflammation and infection), and that neutrophil CD64 is more specific than PCT. Patients admitted to the Department of Gastroenterological Surgery, Akershus University Hospital for elective abdominal surgery will be included in the study after informed consent. Initially consecutive series of 150 patients will be included, but this number may be increased depending on the number of observed infections during the course of the study. All patients will be monitored and treated by the formal protocol related to clinical signs of infection, such as abcess, peritonitis, pneumonia, sepsis and septic shock. In addition to the analytical parameters routinely used today in order to discover infections (CRP, WBC count etc), blood samples for PCT and neutrophil CD64 will be analyzed before surgery and daily during the stay at the hospital. In the case of signs of infection, locally or systemic, the frequencies of analysing PCT and CD64 will be increased according to the severity of the changes in the clinical condition. The expression of CD64 will be measured by flow-cytometry and PCT will be measured by an immunochemical method.
Removal of a central venous catheter (CVC) is often useful to prove its responsibility in a bloodstream infection. To avoid unnecessary removal of CVC, some catheter-spearing diagnostic methods have been recently developed. The aim of the study is to evaluate three catheter-spearing diagnostic methods in critically ill children: 1) the measurement of the differential time to positivity between a blood culture drawn from a peripherical vein and another one drawn through the CVC; 2) the exam of a blood sample drawn for the CVC and stained by acridine orange leucocyte cytospin test; 3) the semi-quantitative skin culture of the area around the insertion site of the CVC.
This phase I clinical trial is studying the side effects and the best dose of vorinostat when given together with paclitaxel and carboplatin in treating patients with metastatic or recurrent solid tumors and human immunodeficiency virus (HIV) infection. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with paclitaxel and carboplatin may kill more tumor cells. NOTE: An administrative decision was made by NCI to halt further study of vorinostat in this specific patient population as of February 1, 2013. No patients remain on vorinostat. Going forward this study will determine the safety and tolerability of the paclitaxel and carboplatin combination in this patient population.
The purpose of this study is to study the prevalence of EBV, HCMV, HHV-6 in saliva and on the toothbrush patient with periodontitis.
The incidence of pin site infection is related to the nursing management of external fixation.
Sepsis contributes to nearly 20% of all hospital deaths and is the leading cause of death on non-coronary intensive care units. Contamination of the patient environment is common with organisms such as MRSA, VRE and C.difficile remaining viable for days or weeks on a variety materials and surfaces. Up to 90% of patient notes and charts on critical care may be contaminated with potential pathogens including MRSA and it has been shown that healthcare workers may contaminate hospital paperwork with organisms originating from patients. Cellomed is a triclosan based laminate which has been shown to possess antimicrobial activity against MRSA, E.Coli, Enterococcus, Stenotrophomonas and Klebsiella. The study presented for consideration aims to compare levels of contamination between critical care observation charts coated with either a 'standard' matt or antimicrobial Cellomed laminate. It is proposed that paperwork laminated with Cellomed may exhibit reduced levels of contamination and decrease the potential for cross infection on critical care and potentially other areas of the hospital in which clinical paperwork is handled.
The primary objective is to assess the immunogenicity and safety and tolerability of two consecutive doses of H5 VLP Influenza vaccine given 21 days apart, at three dose levels: in part A: 20 µg, 30 µg and 45 µg combined with Alhydrogel® 1%, or 45 µg without Alhydrogel®, compared to the placebo, (100mM phosphate buffer + 150mM NaCl + 0.01% Tween 80).
This is a randomized trial to test a brief single session risk reduction counseling intervention on HIV and STI behavioral outcomes in Cape Town South Africa.
