A New Test that Rapidly Detects Blood Infections

Health Care Comments Off

A new simple and inexpensive test can identify bacteria in the blood in less than 20 minutes. The method combines a selective lysis step in which blood cells in the sample are destroyed, a centrifugation step to collect any bacteria or fungi in the sample

and a fluorescence step that analyzes the particular fingerprint of any pathogens present in the sample. It can correctly identify the species of bacteria or fungi in 96.5% of positive blood culture samples.

Lowering BP No Help in Acute Stroke

Health Care Comments Off

Use of antihypertensive drugs to lower systolic blood pressure by close to 13% as part of acute treatment of ischemic stroke did not reduce early mortality or disability compared with patients who did not receive antihypertensive therapy.

At 14 days after randomization, there were 683 events among patients who received early aggressive antihypertensive therapy versus 681 events in the control group and at 3 months, there were 500 additional events in the treatment arm versus 502 among controls, said Jiang He, MD, PhD, of Tulane University School of Public Health in New Orleans.

He reported the findings from China Antihypertensive Trial in Acute Ischemic Stroke (CATIS) at the American Heart Association scientific sessions here and the results were simultaneously published online by the Journal of the American Medical Association. (MedPage)
