ARLINGTON, Va., October 21, 2020 -- A new clinical guideline from the American Society for Radiation Oncology (ASTRO) provides guidance for physicians who use radiation therapy to treat patients with locally advanced rectal cancer. Recommendations outline indications and best practices for pelvic radiation treatments, as well as the integration of radiation with chemotherapy and surgery for stage II-III disease.
A peace sign from Martin Luther King, Jr, becomes a rude gesture; President Donald Trump's inauguration crowd scenes inflated; dolphins in Venice's Grand Canal; and crocodiles on the streets of flooded Townsville - all manipulated images posted as truth.
Image editing software is so ubiquitous and easy to use, according to researchers from QUT's Digital Media Research Centre, it has the power to re-imagine history.
And, they say, deadline-driven journalists lack the tools to tell the difference, especially when the images come through from social media.
Distance studying and working is on the rise and, especially now with the constant threat of lockdown, learning how to master it more pressing than ever.
Palliative care should extend across China and pay more attention to managing non-malignant disease - integrated within the country's healthcare system and available to everyone who needs it, according to a new study.
Researchers have found that, with rapidly aging populations, there is an increasing need for palliative care across Greater China - Hong Kong, Macao, mainland China and Taiwan - to help improve quality of life, as well as reducing pain, anxiety and depression.
A low dose of ketamine, administered intravenously, does not alter a healthy human's tolerance to blood loss. In other words, if someone was given ketamine to kill pain associated with a battlefield injury, they would be able to tolerate blood loss just as well as someone who did not received this pain killer.
That's according to new research published today in The Journal of Physiology.
Using a new mathematical approach to screen large groups for Covid-19 could be around 20 times cheaper than individual testing, a study suggests.
Applying a recently created algorithm to test multiple samples in one go reduces the total number of tests needed, lowering the cost of screening large populations for Covid-19, researchers say.
This novel approach will make it easier to spot outbreaks early on. Initial research shows it is highly effective at identifying positive cases when most of the population is negative.
Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces.
Americans strongly reduced their visits to grocery stores, pharmacies, and transit stations following stay-at-home orders from mayors and governors earlier this year, but did not reduce their visits to parks and beaches, according to a study co-authored by a researcher at the Johns Hopkins Bloomberg School of Public Health.
Among U.S. patients diagnosed with breast, prostate, lung, or colorectal cancer from 2004 to 2016, those who were uninsured or had Medicare or Medicaid were less likely than privately insured patients to receive surgical care at high-volume hospitals. The findings are published in CANCER, a peer-reviewed journal of the American Cancer Society (ACS).
Among women with breast cancer, colorectal cancer, or melanoma, those who were taking cholesterol-lowering medications, were less likely to die from cancer, according to an analysis published in the British Journal of Clinical Pharmacology.
WILMINGTON, Del. (October 21, 2020) - Critically ill newborns who receive blood transfusions prior to surgery had about a 50% increased rate of complications or death than those who did not receive transfusions, according to a new study published today in Pediatrics by Nemours Children's Health System researchers. The findings demonstrate the potential danger that blood transfusions may have on the surgical outcomes of neonatal patients.
What The Study Did:
In this survey study of U.S. adults, vaccine-related attributes and political characteristics were associated with self-reported preferences for choosing a hypothetical COVID-19 vaccine and self- reported willingness to receive vaccination. These results may help inform public health campaigns to address vaccine hesitancy when a COVID-19 vaccine becomes available.

PULLMAN, Wash. -- Washington State University scientists have developed a method to detect the biomarkers for Alzheimer's disease that is 10 times more sensitive than current blood testing technology.
While still in the initial stages of development, the research could lead to earlier detection of the neurodegenerative brain disease that affects 5.8 million people in the U.S. That number is predicted to rise to 14 million Americans by 2050.
What The Study Did: Whether treatment with tocilizumab in the first two days after being admitted to an intensive care unit was associated with a reduced risk of death among critically ill patients with COVID-19 was investigated in this study.
