This wireless device can detect heart dysfunction in cancer survivors

June 25, 2018 Loknath DasCan, Cancer, detect, Device, dysfunction, Heart, In, Survivors, This, Wireless

Scientists have designed a novel wireless device which may accurately detect heart dysfunction in children who have survived cancer. Childhood cancer survivors are advised to undergo screening for the detection of heart dysfunction because of known anthracycline-induced cardiotoxicity. However, screening with echocardiography — the standard of care for monitoring heart function — can be highly variable and limited. Another alternative is cardiac magnetic resonance (CMR) imaging, which is expensive and is not widely accessible. In the study, the team tested Vivio — a prototype handheld instrument which collects pulse waves…

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 —…

New imaging technique to detect onset of vision loss

Researchers have developed a new non-invasive retinal imaging technique that could prevent vision loss in diseases like glaucoma – the second leading cause of acquired blindness worldwide. The new technique called multi-offset detection, which images the human retina — a layer of cells at the back of the eye that are essential for vision — was able to distinguish individual retinal ganglion cells (RGCs), which bear most of the responsibility of relaying visual information to the brain. The death of these RGCs causes vision loss in glaucoma, the researchers said.…

Sensor To Detect Vitamin B12 Deficiency In a Jiffy

Researchers from University of Adelaide have developed a world’s first optical sensor that can detect vitamin B12 in diluted human blood – a novel step towards developing a low-cost and portable deficiency test. Vitamin B12 deficiency is associated with an increased risk of dementia and Alzheimer’s disease. Such a device would enable the tracking of vitamin B12 levels in high-risk patients and early intervention can help overcome the limitations of current testing methods which are time-consuming and costly. “Vitamin B12 deficiency has been shown to be a potential modifiable risk…

First next-gen test can detect drug-resistant HIV

First next-gen test can detect drug-resistant HIV (Getty Images) A first-of-its-kind next-generation sequencing test, which can detect HIV drug resistance mutations that conventional tests fail to identify, can be a weapon in the war against AIDS, suggests a new study. Developed by researchers led by Gerd Michel, Charlie Lee and Elian Rakhmanaliev from Vela Diagnostics in Singapore, this test could play a critical role in helping clinicians to optimize HIV treatment regimens, while also helping public health initiatives to minimize the development of global resistance to antiretroviral drugs. Testing for…
