  • COSTA MESA, Calif.--(BUSINESS WIRE)--May 15, 2007 - Synthetic Blood International, Inc. (OTCBB:SYBD) today announced positive data from a statistical analysis of its Phase IIa study with Oxycyte(TM) in patients with traumatic brain injury. (drugs.com)
  • This analysis further validates our initial study findings that Oxycyte is more effective in increasing brain oxygen tension levels and impacting other brain chemistries that contribute to more favorable clinical outcomes in patients with traumatic brain injury, than breathing either 100% or 50% oxygen alone," said Robert Nicora, president and CEO. (drugs.com)
  • Based on these positive results, we are working with Virginia Commonwealth University (VCU) to develop a protocol for a multicenter, controlled Phase IIb trial that could enroll up to 100 patients with traumatic brain injury. (drugs.com)
  • In this open label, Phase II proof-of-concept, eight-patient study conducted at Virginia Commonwealth University, Oxycyte was administered to patients with severe traumatic brain injury and a Glasgow Coma Scale score of 3-9. (drugs.com)
  • The primary purpose of this study is to demonstrate Oxycyte's ability to increase brain oxygen tension and favorably affect other brain chemistries that impact clinical outcome in patients suffering severe head injury. (drugs.com)
  • From time to time every psychiatrist comes across patients whose problems are at least in part related to the neuropsychiatric consequences (behavioral, cognitive, and emotional) of traumatic brain injury (TBI). (psychiatrictimes.com)
  • The neuropsychiatric assessment starts by evaluating the severity of brain injury. (psychiatrictimes.com)
  • In this way, the likely outcomes attributable to direct effects of brain injury can be determined, and any mismatch between these and what is observed can be attributed to psychological reactions or independent events. (psychiatrictimes.com)
  • So, for example, in somebody with a severe psychotic illness that develops 3 months after an injury with no loss of consciousness, one can be fairly confident that the illness is not a direct consequence of the effects of brain injury on delusion formation. (psychiatrictimes.com)
  • It is possible that the psychological trauma of the injury has allowed an acute psychotic reaction, or even that the injury was irrelevant and that the person was on the path to becoming schizophrenic anyway. (psychiatrictimes.com)
  • On the other hand, it is likely that the psychotic illness is a direct effect of the brain injury in somebody in whom a delusional misidentification syndrome develops 3 months after an injury that was followed by coma for a week and delirium for several weeks. (psychiatrictimes.com)
  • The duration of PTA is particularly useful as a measure of the severity of the brain injury because it can be measured retrospectively, eg, in the clinic years after injury, and it is a good predictor of outcome. (psychiatrictimes.com)

  • A limited trauma-induced coagulopathy as evidence by prolonged PT levels has been found in patients hospitalized for head injury, but PT levels return to normal after 12 hours and the clinical importance of this prolongation is currently unclear. (medscape.com)
  • For example, in a group of 909 consecutive patients who had experienced a mild head injury with a transient loss of consciousness, yet scored a full 15 on their initial GCS, all 57 (6%) patients with abnormal CT scans were identified by the presence of any one of the following clinical features: age older than 60 years, headaches, vomiting, alcohol or drug intoxication, trauma above the clavicles, memory problems, or seizures. (medscape.com)
  • The purpose of this research is to identify a biomarker to predict complications of brain injury, allowing us to decrease the severity and number of poor outcomes. (grantome.com)
