A study found high-sensitivity total-body PET/CT imaging using 18F-fluciclovine may have a role in detecting biochemically recurrent prostate cancer, researchers reported at the 2021 American Association for Radiation Oncology Annual Meeting. The single-institution study, which was published in the International Journal of Radiation Oncology*Biology*Physics, found detection rates "compared favorably to the published historical controls using fluciclovine or even PSMA on conventional PET/CT scanners."
The mortality rate for Parkinson's disease increased 63% in the past two decades, according to a study published in Neurology. Data showed the death rate was twice as high for men, compared with women, and increased for all age groups, both sexes, among racial and ethnic groups, and for urban-rural classifications.
An animal-model study published in the journal Brain, Behavior, and Immunity linked a diet high in processed foods to memory impairment, when compared with a healthy diet. "These findings indicate that consumption of a processed diet can produce significant and abrupt memory deficits -- and in the aging population, rapid memory decline has a greater likelihood of progressing into neurodegenerative diseases such as Alzheimer's disease," said researcher Ruth Barrientos.
Two-thirds of pediatric epilepsy cases may be associated with hypovitaminosis D, according to a cross-sectional retrospective cohort study published in BMC Pediatrics. The researchers found that, out of 138 pediatric epilepsy patients who received anticonvulsants from April 2018 to January 2019, the prevalence of vitamin D insufficiency was at 47.8% and deficiency was at 23.2%.

An ensemble forecast from the CDC predicts daily new COVID-19 case totals will continue to drop by about 20% over the next three weeks. As of Oct. 24, the US seven-day average for new COVID-19 cases had fallen by 57% since Sept. 1, and case rates are decreasing in every US region.
Fifty-one percent of physicians surveyed by Sermo said misinformation spread on social media is an obstacle when treating patients, particularly during the COVID-19 pandemic. They say "social media health literacy" should be taught in medical schools.
The White House said states have submitted orders for Pfizer/BioNTech pediatric COVID-19 vaccines in anticipation of possible FDA emergency use authorization for children ages 5 to 11. Shipments will begin immediately if authorization is granted, and vaccination could begin as soon as next week.
The American Cancer Society has given the Indiana University-Purdue University Indianapolis a $792,000 grant to study how replication errors in DNA can affect cancer. "To better grasp this hugely complex process of DNA replication and repair within our cell, we need to study individual interactions between protein and DNA," said grant recipient Lata Balakrishnan, an associate professor of biology.
As telehealth use increased rapidly in the early months of the pandemic, patients, health plans and health care professionals got a rapid education in the value of telehealth along with the challenges of pivoting to video, phone, text and other modes of communication. Included Health's Dr. Prentiss Taylor sees value in developing virtual-first models and training clinicians as virtualists who can make the most of the medium, while Wellframe's Mohammad Jouni urges health plans to think about telehealth as the sum of all remote interactions and serve as data integrators who can bridge silos and connect all ways of delivering care.
