Providing Ultrasound Information to Enhance Patient Care and Safety
Unenhanced MRI can be used instead of CT imaging on children with suspected appendicitis when sonographic findings are equivocal, researchers reported in Radiology. The retrospective study revealed the staged algorithm had a negative predictive value of 99.5%, more than 98% overall sensitivity and specificity above 97%.
An experimental optoacoustic device identified BI-RADS 3 breast lesions with a specificity of 43% and sensitivity of 96%, compared with 28.1% and 98.6%, respectively, for grayscale ultrasound, according to a study presented at the Radiological Society of North America's annual conference. The ability to downgrade some benign masses could help decrease false-positive examinations, biopsies and short-term follow-up exams, said investigator Dr. Erin Neuschler of Northwestern University.
OpenEMR, an open-source EHR management application, has a vulnerability in its configuration that has the potential to expose more than 90 million patients' records, according to a blog post by researchers at Risk Based Security. The official OpenEMR documentation recommends blocking or removing access to the original setup script, but the instruction "is far too vague" and "fails to properly warn about the risks of not doing so," said Sven Krewitt of RBS.
The number of health care companies filing for bankruptcy protection has grown substantially this year, and lawyer David Neier expects more hospitals and other medical companies to restructure their debt or file for bankruptcy next year. The growth in high-deductible health plans and reductions in federal funds for disproportionate share hospitals are among the factors squeezing revenue, experts say.
Streamlining Clinical Workflows in Vascular Ultrasound Spectral Doppler imaging is commonly performed to quantify flow profiles in blood vessels. The measurement is displayed as a waveform trace, depicting the velocity distribution (profile) at the given spatial location as a function of time. Capturing the velocity profile requires five steps…
An international survey on techniques for transfemoral access for coronary angiography in 88 countries found wide variation in approaches, with 60% using pulse palpation, 11% fluoroscopy guidance and 27% a combination of palpation, fluoroscopy or ultrasound. Close to 100% said they preferred the Judkins left and right catheters to access coronary arteries for diagnostic angiography.
The FDA has issued final guidance saying that X-ray imaging device manufacturers should add pediatric use indications in their premarket notifications and offer labeling recommendations, while imaging professionals should only perform X-rays on children when necessary and use the lowest radiation dose possible that can still produce clear images. Considerations for children, risk assessments and safety features that may be added to X-ray devices, such as pediatric presets and automatic exposure control, were also included in the recommendations.
Losing weight by dieting or by dieting and exercising can slow the progression of knee osteoarthritis in overweight people, but losing weight by exercising alone did not significantly slow cartilage degeneration in a study to be presented at the Radiological Society of North America annual meeting.
An American Cancer Society study showed 42% of all cancers diagnosed in 2014, along with more than 45% of cancer deaths, were associated with 17 modifiable risk factors, with the top three being smoking, excessive weight and alcohol use. The study published in CA: A Cancer Journal for Clinicians found 85.8% of lung cancer cases, more than 70% of liver cancer cases, nearly 55% of colorectal cancer cases and almost 29% of breast cancer instances were linked to modifiable risk factors.
CMS Administrator Seema Verma announced that the new quality reporting framework using "meaningful measures" should ease regulatory burdens on physicians, but providers have raised concerns over whether the framework can really reduce burden, and some are still uncertain about which measures they need to report on. Jennifer McLaughlin of the Medical Group Management Association said the program is "simply conceptual" and "has very little substance behind it."
