New optical diagnostic technology developed at Tufts University School of Engineering promises new ways to identify and monitor brain damage resulting from traumatic injury, stroke or vascular dementia — in real time and without invasive procedures. Coherent hemodynamics spectroscopy (CHS), developed and published by Tufts Professor of Biomedical Engineering Sergio Fantini, measures blood flow, blood [...]

Patients Given Less Blood During Transfusions Do Well

Jeffrey Carson says it is clearer than ever that smaller transfusions are better for many patients than larger ones.

Patients with heart disease who receive transfusions during surgeries do just as well with smaller amounts of blood and face no greater risk of dying from other diseases than patients who received more blood, according to a new Rutgers study. The research, published in the journal Lancet,measures overall mortality and mortality from cardiovascular disease, cancer [...]

Organic Electronics Could Lead To Cheap, Wearable Medical Sensors

UC Berkeley engineers have created a pulse oximeter sensor composed of all-organic optoelectronics that uses red and green light. The red and green organic light-emitting diodes (OLED) are detected by the organic photodiode (OPD). The device measures arterial oxygen saturation and heart rate as accurately as conventional, silicon-based pulse oximeters.

Future fitness trackers could soon add blood-oxygen levels to the list of vital signs measured with new technology developed by engineers at UC Berkeley. “There are various pulse oximeters already on the market that measure pulse rate and blood-oxygen saturation levels, but those devices use rigid conventional electronics, and they are usually fixed to the [...]

Prototype Point-Of-Care Analyzer Enables Early Ebola Detection

Driven by the ambitious objective to quickly detect the Ebola virus in the blood at a very early stage to minimize further transmission, STMicroelectronics and Clonit, in collaboration with Italy’s National Institute for Infectious Diseases Lazzaro Spallanzani, have developed, in a few weeks’ time, a prototype portable analyzer able to identify the presence of the [...]

Genome Sequencing Traces MRSA Spread In High Transmission Setting

Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of hospital-acquired infections, with the largest burden of infections occurring in under-resourced hospitals. While genome sequencing has previously been applied in well-resourced clinical settings to track the spread of MRSA, transmission dynamics in settings with more limited infection control is unknown. In a study published online  in [...]
