For COVID-19 surveillance, test frequency and turnaround time are paramount, modeling suggests
Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance, suggests a new study that modeled trade-offs in test sensitivity, test frequency, and sample-to-answer reporting time, in select scenarios. Test sensitivity is secondary to these factors in the scenarios studied. (2020-11-20)

'Rare' brain disorder may not be so rare anymore, trends in japan reveal
Creutzfeldt-Jakob disease (CJD), a fatal neurodegenerative disorder, is an important cause of dementia. However, long-term trends in CJD-associated mortality and incidence rates in Japan have not been fully studied until now. Now, scientists conducted a detailed analysis that uncovered that the CJD-associated death and incidence rates almost doubled from 2005-2014. They predict that the burden of CJD would continue to rise in the current hyper-aging era. These findings can help policymakers plan and strategize effectively. (2020-10-19)

High-risk patients for colorectal cancer lack knowledge about colonoscopy
Many clinicians rely on self-reports from their high-risk patients about their need and proper interval for repeat surveillance colonoscopy. Researchers analyzed data on high-risk patients and found that 28 percent were unaware of either the need for a repeat colonoscopy or the proper surveillance interval. Of these, 16.6 percent were unaware of the proper three-year interval to obtain a follow-up surveillance colonoscopy. Also, 12 percent did not know that they required a follow-up surveillance colonoscopy. (2020-09-14)

Researchers identify evolutionary origins of SARS-CoV-2
By reconstructing the evolutionary history of SARS-CoV-2, the virus that is responsible for the COVID-19 pandemic, an international research team of Chinese, European and U.S. scientists has discovered that the lineage that gave rise to the virus has been circulating in bats for decades and likely includes other viruses with the ability to infect humans. The findings have implications for the prevention of future pandemics stemming from this lineage. (2020-07-28)

Video camera in a public place knows the density of people or vehicle more accurately
Deep learning applied for image/video processing opened the door for the practical deployment for object detection and identification with acceptable accuracy. Crowd counting is another application of image/video processing. The scientists at Japan Advanced Institute of Science and Technology (JAIST) designed a new DNN with backward connection, which achieved more accurate estimation of the density of objects. It can be applied for estimating human density in the public or vehicle density on a road. (2020-07-27)

Prostate cancer: How can we decide when to treat?
You have been diagnosed with prostate cancer and your doctor gives you the option of not being treated, but of remaining under observation: is there any objective way you can decide to be treated or not treated? What should you do? Now using first results from analysis of the world's biggest Active Surveillance prostate cancer database, scientists have begun to identify which patients are at risk of the disease developing and which patients can continue to safely delay treatment.
