The shift from film to digital technology appears to have improved cancer detection rates for diagnostic mammography, but also has increased the abnormal interpretation rate, which may lead to more women undergoing biopsies for benign conditions, according to a new study.
Light beamed into a patient's blood through an optical fiber can determine whether blood is clotting during an operation, continuously and in real time. Researchers believe it could take the place of traditional blood tests in some situations and have myriad healthcare applications.
The most prevalent method for obtaining images of clogged coronary vessels is coronary angiography. For some patients, however, the contrast agents used in this process can cause health problems. A team at the Technical University of Munich (TUM) has now demonstrated that the required quantity of these substances can be significantly reduced if monoenergetic X-rays from a miniature particle accelerator are used.
Scientists at Rutgers and other universities have created a new way to identify the state and fate of stem cells earlier than previously possible. Understanding a stem cell's fate -- the type of cell it will eventually become -- and how far along it is in the process of development can help scientists better manipulate cells for stem cell therapy.
Several newly discovered variants of a gene increase the risk of developing anxiety disorders. A research team aims to derive new therapies from this finding which are better tailored to the individual patients.
For the first time a molecular 'tipping point' has been demonstrated in Alzheimer's, linking high blood sugar with this debilitating disease
Researchers have identified a novel mutation that may be associated with prostate cancer in African-American men, according to a new study published in PLOS Computational Biology. Scientists have long known that a huge variety of DNA mutations can lead to cancer. Some proteins can repair DNA mutations, but when repair proteins are mutated themselves, cancer may arise. Knowing which mutations are linked to which cancer types helps scientists develop new targeted treatments and detection strategies.
It may seem obvious, but the key to confirming whether someone is suffering from a cold or flu virus might lie at the misery's source -- the inflamed passages of the nose and throat. Duke Health scientists have identified a group of proteins that, when detected in specific quantities in the mucous, are 86 percent accurate in confirming the infection is from a cold or flu virus, according to a small, proof-of-concept trial published online in the journal EBioMedicine.
Using data from the world's largest CT dose index registry, researchers have established national dose levels for common adult CT examinations based on patient size. Healthcare facilities can optimize these exam protocols so that dose is commensurate with the size of the patient, avoiding unnecessary radiation exposure.
Death rates from cancer in the European Union (EU) are falling faster in men than in women, according to the latest predictions for European cancer deaths in 2017, published in the leading cancer journal Annals of Oncology. Compared with 2012, death rates in men will fall by just over eight percent to 132 per 100,000 of the population in 2017, while in women the decline will be around four percent to 84.5 per 100,000.
