Machine learning can predict low blood pressure during surgery

Machine learning can predict low blood pressure during surgery

Health
June 11 (UPI) -- A new algorithm can predict potentially dangerous low blood pressure during surgery. Researchers have developed machine learning than can identify hypotension as much as 15 minutes before it occurs, and are correct about 84 percent of the time. The findings were published Monday in the journal Anesthesiology. "Physicians haven't had a way to predict hypotension during surgery, so they have to be reactive, and treat it immediately without any prior warning," Dr. Maxime Cannesson, a professor of anesthesiology at UCLA Medical Center in Los Angeles, said in a press release. "Being able to predict hypotension would allow physicians to be proactive instead of reactive." Canesson said the tool can save lives -- even with a warning only 10 to 15 minutes ahead of time. "By findi...
Blood test detects cancer years before symptoms

Blood test detects cancer years before symptoms

Technology
Ten types of cancer could be detected years before a person falls ill thanks to a new blood test, according to scientists. The test is being hailed as the "holy grail of cancer research" after a trial of about 1,600 people found it could identify DNA markers with up to 90% accuracy.It detected genetic traces of multiple cancers, including breast, pancreatic and ovarian, according to the study led by Cleveland Clinic in Ohio, US.The findings will be presented at the annual meeting of the American Society of Clinical Oncology (ACSO) in Chicago this weekend.Simon Stevens, NHS England chief executive, said the test could "dramatically transform" cancer care.Dr Eric Klein, lead author of the study, told The Daily Telegraph: "This is potentially the holy grail of cancer research,...
Nanorobots help remove bacteria, toxins from blood

Nanorobots help remove bacteria, toxins from blood

Health
May 31 (UPI) -- Nanorobots that are about 25 times smaller than the width of a human hair have been developed to remove harmful bacteria and toxins by swimming through the bloodstream. Engineers at the University of California San Diego hope one day their proof-of-concept method will offer a safe and efficient way to detoxify and decontaminate biological fluids. Their findings were published Wednesday in the journal Science Robotics. "The idea is to create multifunctional nanorobots that can perform as many different tasks at once," co-first author Berta Esteban-Fernandez de Avila, a postdoctoral scholar at UC San Diego, said in a press release. "Combining platelet and red blood cell membranes into each nanorobot coating is synergistic -- platelets target bacteria, while red blood cells ...
Changes to tiny blood vessels may help diagnose traumatic brain injuries

Changes to tiny blood vessels may help diagnose traumatic brain injuries

Health
April 30 (UPI) -- By finding changes to tiny blood vessels in the brains of people with traumatic injuries, researchers believe medical personnel could be able to make more precise diagnosis and treatment decisions.Researchers found that changes in the blood vessels may be linked to a range of cognitive symptoms after a traumatic brain injury, or TBI. The research, which was led by the University of Pennsylvania, was presented Friday at the American Academy of Neurology Annual Meeting and has not yet been published."The relationship between microvascular and structural injury in chronic TBI has been recognized for years, but underappreciated," Dr. Ramon Diaz-Arrastia, director of the Traumatic Brain Injury Clinical Research Center at the Perelman School of Medicine at Pennsylvania, said in...
Research: Blood thinner reduces risk after heart damage in surgery

Research: Blood thinner reduces risk after heart damage in surgery

Health
March 12 (UPI) -- A blood-thinning drug significantly reduces the risk of complications from a heart injury after major non-cardiac surgery, report researchers in Canada.Researchers found dabigatran was effective in the first randomized controlled study to evaluate ways to reduce such heart injuries, according to study results presented last week at the American College of Cardiology's annual conference in Orlando last week. Dabigatran is sold under the brand name Pradaxa, which is made by Boehringer Ingelheim, a drugmaker that helped fund the study.The study was conducted by the Population Health Research Institute of McMaster University and Hamilton Health Sciences in Ontario, Canada."We now have an option for improving outcomes for a large population of people who have a heart injury af...
