Surgical eye robot performs precision-injection in patient with retinal vein occlusion (Health)
Posted by: Site Administration
Surgeons of University Hospitals Leuven have been the first to operate on a patient with retinal vein occlusion using a surgical robot. Operated by an eye surgeon, the robot uses a needle of barely 0.03 millimetre to inject a thrombolytic drug into the retinal vein of the patient. KU Leuven (University of Leuven, Belgium) developed the robot and needle specifically for this procedure.

Assessment of comatose patients through telemedicine efforts shown to be reliable (Health)
Posted by: Site Administration
Reliable assessment of comatose patients in intensive care units is critical to the patients' care. Providers must recognize clinical status changes quickly to undertake proper interventions. But does the provider need to be in the same room as the patient, or can robotic telemedicine be used successfully to complete the assessment? According to a research study conducted at Mayo Clinic Hospital in Arizona, published in Telemedicine and e-Health, the answer is yes.

Wearable biosensors can flag illness, Lyme disease, risk for diabetes; low airplane oxygen (Health)
Posted by: Site Administration
By following 60 people through their everyday lives, Stanford researchers found that smart watches and other personal biosensor devices can help flag when people have colds and even signal the onset of complex conditions like Lyme disease and diabetes. "We want to tell when people are healthy and also catch illnesses at their earliest stages," said Michael Snyder, PhD, Professor and Chair of Genetics at Stanford and senior author of the study. Postdoctoral scholars Xiao Li, PhD, and Jessilyn Dunn, PhD, and researcher Denis Salins share lead authorship.

Smartphone, Finger Prick, 15 Minutes, HIV / syphilis diagnosis complete (Health)
Posted by: Site Administration
A team of researchers, led by Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, has developed a low-cost smartphone accessory that can perform a point-of-care test that simultaneously detects three infectious disease markers from a finger prick of blood in just 15 minutes. The device replicates, for the first time, all mechanical, optical, and electronic functions of a lab-based blood test. Specifically, it performs an enzyme-linked immunosorbent assay (ELISA) without requiring any stored energy: all necessary power is drawn from the smartphone. It performs a triplexed immunoassay not currently available in a single test format: HIV antibody, treponemal-specific antibody for syphilis, and non-treponemal antibody for active syphilis infection.

New 'lab-on-a-chip' could revolutionize early diagnosis of cancer (Health)
Posted by: Site Administration
Scientists have been laboring to detect cancer and a host of other diseases in people using promising new biomarkers called “exosomes.” Indeed, Popular Science magazine named exosome-based cancer diagnostics one of the 20 breakthroughs that will shape the world this year. Exosomes could lead to less invasive, earlier detection of cancer, and sharply boost patients’ odds of survival.
