Filter by:Neutropenia is very common in patients received hematopoietic stem cell transplantation, with median duration of about 14 days. Almost all neutropenia will suffer from febrile without prophylactic antibiotics. IDSA recommended fluoroquinolones as prophylaxis in neutropenia patients of high risks, while in China, major pathogens possess high resistance to fluoroquinolones. It is not clear whether prophylaxis is of benefit, nor the appropriate prophylaxis regimen. The current study will evaluate the three different regimen: 1. No prophylaxic antibiotic 2. Piperacillin as prophylaxis for neutropenia patients. Piperacillin has anti-pseudomonas activity. 3. Piperacillin/tazobactam as prophylaxis for neutropenia patients. Piperacillin/tazobactam has highest susceptibility rate among common anti-pseudomonas antibiotics.
Pancreatic ductal adenocarcinoma (PDAC) has one of the worst prognoses of all human cancers and is considered as a sanctuary, resistant to most of the drugs used. Identification of new molecular targets involved in its pathogenesis is urgently needed and required both proper and innovative efficacy assessment. This proof-of-concept trial is studying the "dynamic" tumor response after the administration of a short course (4 weeks) neoadjuvant combination of gemcitabine and a Hedgehog inhibitor (Vismodegib) before surgery in patients with operable pancreatic cancer.
Patients under sedation not uncommonly develop upper airway obstruction or other respiratory complications and no airway device is available to provide reliable maintenance of the airway at present. I believe the YO2(R)airway catheter can improve the maintenance of patent airway in most sedated patients and improve O2 delivery to the airway. In addition it may also greatly facilitate the monitoring of expired CO2, which is widely recognised as the most important monitor of adequacy of breathing, yet frequently impossible to perform satisfactorily in sedated patients at the moment.
Carbohydrates are an integral component of sports nutrition. Providing carbohydrate (CHO) during exercise delays the onset of fatigue and improves exercise performance by maintaining high rates of CHO oxidation. Traditionally, glucose, or glucose polymers have been the preferential CHO source found in sports drinks. However, during the intestinal absorption of large amounts of glucose (>1.2 g/min), sodium-dependent glucose transporters (SGLT1) may become fully saturated, potentially limiting the rate of exogenous CHO oxidation. In an effort to evade this limitation, research has suggested using multiple transportable carbohydrates in the composition of sports drinks. Multiple transportable carbohydrates are combinations of simple sugars that use different intestinal transporters during the absorption process. Ingesting multiple transportable carbohydrates may enhance the capacity for total intestinal CHO absorption, leading to an increase in the rate of exogenous CHO oxidation. Our purpose will be to examine the disaccharide sucrose in it's ability to provide exogenous fuel during and following prolonged exercise.
the investigators are assessing a non-invasive monitor based on dynamic light scattering that measures pulse rate and respiration rate. The monitor also will be equipped with a temperature sensor and a motion sensor. This monitor will allow multi-parametric measurements in neonates in a simple and noninvasive manner.
The purpose of the DRAGON clinical trial is to evaluate the safety and efficacy of the transradial coronary intervention (TRI) in comparison with the transfemoral coronary intervention (TFI).
The purpose of this study will evaluate new technologies that have been included in the new PCA-9000A PET/CT System.
Certain types of fractures require surgical intervention that may involve the use of bone grafts or bone graft substitutes. Many of the materials used as bone graft substitutes suffer from disadvantages such as soft tissue invasion of the fracture area, inadequate blood supply, failure to encourage the production of bone and ectopic bone formation. A guided bone regeneration (GBR) environment may help in solving these clinical concerns. GBR has been widely used in the field of dentistry since the 1980s to provide stable placement for dental implants The purpose of this study is to evaluate the safety, performance and initial efficacy of Regenecure's, AMCA Bone Membrane, as a bone stimulating aid for orthopedic trauma applications.
Periconceptional supplementation with folic acid - the synthetic form of the B-vitamin folate - reduces the occurrence of adverse pregnancy outcomes such as spina bifida. The underlying biochemical mechanisms for how folic acid affects health outcomes however are unknown. The naturally occurring form 5-methyltetrahydrofolate (5-MTHF) is now available and discussed as an adequate substitute to folic acid. This study aims to determine the effect of folic acid compared to 5-MTHF on cellular mechanisms. Stable isotope tracer protocols will be used that allow determining the effect of folic acid on the dynamics of metabolic pathways in the human body. Hypothesis: Supplementation with high-dose folic acid alters the turnover rate of folate dependent pathways in healthy humans; but 5-MTHF does not. Genetic variations in a key enzyme of the folate metabolism will aggravate the effect of folic acid on the metabolic pathways.
