New blood test could predict second heart attack risk

A blood test that quickly and easily detects whether a person is at the risk of a secondary heart attack is being developed by scientists. The researchers at the Baker Heart and Diabetes Institute in Australia have identified plasma lipid biomarkers (fats in the blood) that improve upon traditional risk factors in predicting heart disease and stroke. The blood test is proposed to be trialled in Australia over the next 2-3 years, said Peter Meikle, a professor Baker Heart and Diabetes Institute. Eventually this test will help better assess a…

Faster, Safer Lab Test Developed To Diagnose Heart Attacks

Researchers have developed a simple laboratory score which is safer and faster at diagnosing patients who visit the emergency department with heart attack symptoms. The findings, published in the CMAJ (Canadian Medical Association Journal), suggest that the score can also identify patients at risk of subsequent heart issues after discharge. “We have developed a simple lab score that is superior to using cardiac troponin alone for the identification of patients at low and high risk for heart attack or death at emergency department presentation,” said co-author Peter Kavsak from the…

This new blood test can predict due date and premature birth

Researchers from Standford University have developed a new blood test for pregnant women that may detect whether their pregnancies will end in premature birth. The technique can also be used to estimate a foetus’s gestational age — or the mother’s due date — as reliably and less expensively than ultrasound. There have been several studies on preterm births in the past, and the reasons for it. A study by the University of Pennsylvania linked such births to changes in the mother’s bacteria. Another study by CHU Sainte-Justine in Canada found that having a baby…

Dear parents, watch out for these 9 signs that indicate your kid needs an eye test

With the proliferation of screens in our lives – phone screen, tablets, Kindles, computers – television isn’t the only source of eye strain for kids and adults. But, unlike in case of adults, it is harder to gauge when children develop vision issues. “More often than not, vision problems go unnoticed until children begin school,” said associate professor of Ophthalmology Marcela Frazier, “Children grow up naturally adapting to vision issues, so when they get into school and start reading and learning, that is when parents and teachers begin to notice…

Lyft Partners nuTonomy to Test Self-Driving Cars in Boston

Uber rival Lyft said Tuesday it would begin testing autonomous ridesharing in Boston under a partnership with the technology startup nuTonomy. Under the partnership, nuTonomy and Lyft will collaborate to gain insights into “all aspects of ensuring a passenger’s comfort and safety” in self-driving vehicles, a joint statement said. Lyft’s move follows a similar effort by Uber, which has been using autonomous vehicles in a test program in some US cities. “At Lyft, we imagine a world where car ownership is optional and cities are designed for people instead of…

Cheap breath test may detect stomach, oesophageal cancers

Scientists have developed a cheap and non-invasive test that can measure the levels of five chemicals in the breath to detect cancers of the oesophagus and stomach with 85 per cent accuracy. Together, stomach and oesophageal cancer account for around 1.4 million new cancer diagnoses each year worldwide. Both tend to be diagnosed late, because the symptoms are ambiguous, meaning the five-year survival rate for these two types of cancer is only 15 per cent. Currently, the only way to diagnose oesophageal cancer or stomach cancer is with endoscopy —…
