University of Cincinnati researchers have found that certain treatments for cancer may increase the chance of death if they contract COVID-19.
These findings from a multicenter study, presented at the European Society for Medical Oncology Virtual Congress 2020, shed light on ways standard anti-cancer treatments may impact outcomes for patients with both cancer and the coronavirus.
BACKGROUND
Tracking the passage of time to the second is critical for motor control, learning and cognition, including the ability to anticipate future events. While the brain depends on its circadian clock to measure hours and days, the circadian clock does not have a second hand.
Research has found a proposal to regulate mining of Indigenous lands in Brazil's Amazon rainforest could affect more than 863,000 square kilometres of forest and harm the nation's economy.
Led by University of Queensland visiting PhD student Juliana Siqueira-Gay, an international collaboration has warned that President Jair Bolsonaro's 2020 bill to mine inside recognised Indigenous Lands would come at a cost.
"Brazil's Indigenous Lands are unbelievably valuable - socially, ecologically and economically," Ms Siqueira-Gay said.
Global maps of places where people and forests coexist show that an estimated 1.6 billion people live within 5 kilometers of a forest. The assessment, based on data from 2000 and 2012 and published September 18 in the journal One Earth, showed that of these 1.6 billion "forest-proximate people," 64.5 percent were located in tropical countries, and 71.3 percent lived in countries classified as low or middle income by the World Bank.
New Haven, Conn. -- Doctors at Yale New Haven Hospital used a more aggressive selection process to more than quadruple the number of heart transplants performed there while maintaining positive patient outcomes, according to a new study.
The findings suggest that a more inclusive approach to selecting donor hearts and transplant recipients can enable hospitals to successfully treat more patients in need of transplants. The study appears online Sept. 18 in the journal JAMA Network Open.
What The Editorial Says: Authors of this editorial review the evidence for the management of patients with the acute respiratory distress syndrome (ARDS) that may apply to patients with severe COVID-19, what has been learned about treatment of these patients, and the gaps in knowledge that remain.

Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) have made the first direct geometric measurement of the distance to a magnetar within our Milky Way Galaxy -- a measurement that could help determine if magnetars are the sources of the long-mysterious Fast Radio Bursts (FRBs).
CHAMPAIGN, Ill. — Studies indicate that homemade masks help combat the spread of viruses like COVID-19 when combined with frequent hand-washing and physical distancing. Many of these studies focus on the transfer of tiny aerosol particles; however, researchers say that speaking, coughing and sneezing generates larger droplets that carry virus particles.
In March, researchers in the Department of Biomedical Engineering-- a shared department in the schools of Dental Medicine, Medicine, and Engineering--began to develop a new, low-cost, CRISPR-based diagnostic platform to detect infectious diseases, including HIV virus, the novel coronavirus (SARS-CoV-2). Today, the method is one step closer to being a cutting-edge diagnostics technology for rapid detection of infectious diseases.
The melanoma is a malignant tumor of the pigment cells. If diagnosed early, the tumor can be removed completely - and the chances of recovery are good. But in later stages, when the tumor has already spread or formed metastases in other parts of the body, the prospects become worse for those affected.
No effect for a good half of patients
Announcing a new article publication for BIO Integration journal. In this opinion article the authors Fengyi Zeng, Xiaowen Liang and Zhiyi Chen from The Third Affiliated Hospital of Guangzhou Medical University, Guangzhou, China consider new roles for clinicians in the age of artificial intelligence (AI).
By André Julião | Agência FAPESP – Researchers at the University of São Paulo (USP) in Brazil have characterized a novel family of anti-bacterial toxins present in bacteria, including Salmonella enterica. This species uses toxic proteins to kill other bacteria in gut microbiota and facilitate colonization of the infected host’s gut.
The study is published in Cell Reports and featured on the cover of the journal.
A new hollow optical fiber greatly reduces the "noise" interfering with the signals it transmits compared to the single-mode fibers now widely used, researchers at the University of Rochester report.
The anti-resonant hollow-core fiber, created by researchers at the University of Central Florida, produces a thousand times less "noise" - and the lowest levels ever recorded from interference caused by acoustic phonons arising from the glass in the fiber at room temperatures.
Despite the important advances in research in recent years, the etiopathogenesis of Alzheimer's disease is still not fully clarified. One of the key questions is to decipher why the production of beta amyloid, the protein that produces the toxic effect and triggers the pathology, increases in the brain of people with Alzheimer's.
BUFFALO, N.Y. -- Researchers know from many previous studies what prevents cash-strapped shoppers in underserved communities from buying more fresh produce. But little is known about which strategies are most likely to reach the people who need them, or have the most success in improving the diets of people in lower income areas.
