Filter by:The purpose of this study is to establish a reliable method for detection of rectal cancer patients with aggressive tumor at risk of metastatic disease and death by functional MRI.
The study will aim to describe and evaluate the effect of beetroot juice supplementation upon whole body running exercise at altitude. It is hypothesised that beetroot supplementation will decrease time to complete a 10 km time trial.
This study is a randomized, controlled trial to assess safety and effectiveness of whole body hypothermia for 72 hours in preterm infants 33-35 weeks gestational age (GA) who present at <6 hours postnatal age with moderate to severe neonatal encephalopathy (NE). The study will enroll infants with signs of NE at 18 NICHD Neonatal Research Network sites, and randomly assign them to either receive hypothermia or participate in a non-cooled control group.
The purpose of this study is to determine the efficacy of high dose Erythropoietin to improve survival and neurologic outcome in asphyxiated term newborn undergoing cooling.
During early postoperative after lung resection surgery, patients without oxygen supplementation may experience hypoxemia. Oxygen supplementation can be given via oxygen mask or cannular. In this study the investigators want to the sudy the effect of oxygen supplementation via oxygen cannular during the first 120 minutes after surgery
At our institute,during the first 2 hour postoperative, we used to give supplement oxygen via face mask in patient having lung resection surgery. After then if the patient is fine, we'll replace the face mask with nasal cannular untie the next morning. We hypothesized that oxygen mask can be replace by nasal cannular without any hypoxia.
The primary objective is to study if an inhibition of nitric oxide and/or prostaglandins affect the diameter changes of retinal vessels observed during hypoxia. Diameter changes are studied using the Dynamic Vessel Analyzer.
The purpose of this study is to determine the efficacy and safety of nasal high flow oxygen therapy during diagnostic bronchoscopy.
The present study is a randomized, prospective, single-blinded study. Patients presenting for colonoscopy under sedation will be included according to the statistical sample size calculation. Patients will be randomized to either group 1- capnographic monitoring or group 2- oxygenic monitoring during Propofol-based sedation for colonoscopy. Episodes of Hypoxia are documented and compared in both groups.
Intracranial Hemorrhage (ICH) is an important morbidity affecting premature infants and can have considerable effects on neurodevelopmental outcome. The investigators showed that preterm infants with severe ICH have decreased cerebral oxygenation several weeks after the hemorrhage. The mechanisms involved in this state of decreased cerebral oxygenation in preterm infants and the effects on cerebral function are unknown. This longitudinal observation study will evaluate physiologic parameters to determine trends in cerebral oxygenation and function in preterm infants with ICH in comparison to infants without ICH.
