Saliva of vampire bats aids stroke victims
The brain of stroke victims could be protected by a drug manufactured from the saliva of vampire bats. Normally, most stroke patients should get into hospital for "clot-busting" treatment within a few hours. However, it appears the drug Desmoteplase can make a difference even if given nine hours after the stroke.  more

Desmoteplase in stroke: Successful phase II results
The DIAS study (Desmoteplase In Acute Ischemic Stroke) was a multicentre, placebo-controlled, randomized dose finding Phase II study. 25 hospitals from Europe, Australia and Asia recruited a total of 102 patients. Patients were included in the time window between three and nine hours after the onset of stroke symptoms. A sister study DEDAS ("Dose Escalation study of Desmoteplase in Acute Ischemic Stroke") is ongoing in 17 centers in the US with the same study design. In both studies MRI was used to identify patients who have the potential to benefit most from reperfusion therapy.  more

Blood-diverting catheter holds promise for stroke treatment
A new catheter device that diverts some blood from the lower body to the brain appears safe for treating acute stroke and may significantly reduce stroke complications – even after a critical treatment window has lapsed.  more

Avian influenza A(H5N1) update: Investigation of possible human-to-human transmission in Viet Nam - New data are reassuring
WHO has today received the results from studies of two viruses taken from members of a family cluster of H5N1 infection in Viet Nam. The family cluster has been under investigation as the first possible instance of limited human-to-human transmission of the H5N1 avian influenza strain. Virus genetic materials from two fatal cases in this cluster – sisters aged 23 and 30 years – have now been fully sequenced by the Government Virus Unit of Hong Kong’s Department of Health. Both viruses are of avian origin and contain no human influenza genes. more
