What is medical extended reality? New AMXRA guideline

Statement Highlights: Despite significant advances in research, education, clinical practice and community-based programs, survival from cardiac arrest remains low. Significant disparities also exist in cardiac arrest outcomes. This scientific statement specifically identifies impact goals to achieve or exceed by 2030 to improve cardiac arrest for all people. DALLAS, January 22, 2024 — Only 10% of people who experience a cardiac arrest survive.[1] In new challenge goals outlined in the American Heart Association Emergency Cardiovascular Care 2030 Impact Goals and Call to Action to Improve Cardiac Arrest Outcomes, the American Heart Association’s volunteer ...

“An improved understanding of the molecular basis of thyroid cancer has led to the development of new targeted agents.” BUFFALO, NY- January 29, 2024 – A new research perspective was published in Oncotarget's Volume 15 on January 24, 2024, entitled, “Genetic alterations in thyroid cancer mediating both resistance to BRAF inhibition and anaplastic transformation.” In this new paper, researchers Mark Lee and Luc GT Morris from New York Presbyterian Hospital and Memorial Sloan Kettering Cancer Center discuss thyroid cancer. A subset of thyroid cancers present at advanced stage or with dedifferentiated histology and have limited response to standard therapy. ...

Previous studies focused on cocaine use have found that women are more likely than men to develop an addiction, try cocaine at a younger age, use larger amounts of the drug, and suffer from overdose. Now, a new study from researchers at The University of Texas at Arlington in the journal Pharmacology Biochemistry and Behavior finally validates what scientists have long suspected: The female sex hormone estradiol (a synthetic version of the naturally occurring estrogen) is responsible for why women are more susceptible to cocaine addiction than men. “For the first time, we have shown that estradiol enhances the cocaine-conditioned reward,” said Linda Perrotti, ...

By Ileana Wachtel January 29, 2024 Chinese citizens who rarely voice open criticism of their government reveal stronger negative views when they can answer questions anonymously, according to a new study published in The China Quarterly. The study by researchers at the USC Dornsife College of Letters, Arts and Sciences shows an enormous drop in citizen support for the Chinese Communist Party (CCP) and government policies when citizens are surveyed using a method that hides their identities and makes them feel more anonymous than a typical survey. Why ...

COLUMBIA, Mo. -- School nurses are more than just health care heroes. They also play a key role in identifying students who are at risk for chronic absenteeism — a growing problem that diminishes academic success and can hurt students’ health and lead to a variety of negative long-term life outcomes. A recent study by a University of Missouri researcher found that school nurses are often well-positioned to identify students at-risk for chronic school absenteeism. The finding could help schools implement assessments and interventions to ultimately better support students ...

LA JOLLA, CA — Nerve cells in the brain demand an enormous amount of energy to survive and maintain their connections for communicating with other nerve cells. In Alzheimer’s disease, the ability to make energy is compromised, and the connections between nerve cells (called synapses) eventually come apart and wither, causing new memories to fade and fail. A Scripps Research team, reporting in the journal Advanced Science on January 18, 2024, has now identified the energetic reactions in brain cells that malfunction and lead to neurodegeneration. By using a small molecule ...

HOUSTON – (Jan. 29, 2023) – Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place. The find is detailed in a study published in Nature Physics. The paper also describes the theoretical design principle and experimental methodology that guided the research team to the material. One part copper, two parts vanadium and four parts sulfur, the alloy features a 3D pyrochlore lattice consisting ...

It has long been known that agricultural pesticides are one of the greatest threats to bees and other essential pollinators. What farmers have lacked is an understanding of how different pesticides, applied at various times on a variety of crops, affect the risk of exposure to bees living near the fields. Researchers have drawn from real-world data to try to address this gap, developing and testing a spatial model for predicting pesticide exposure in bumblebees. The journal Science of the Total Environment published the work, based on the interactions of the yellow-faced bumblebee (Bombus vosnesenskii) ...

EMBARGOED UNTIL MONDAY, 29 JANUARY 2024, 21:00 CET (20:00 LONDON TIME, 15:00 U.S. EASTERN TIME) Have you ever seen a hummingbird hawk moth? When people encounter this moth for the first time, they are usually intrigued: Looking like a cross between a butterfly and a bird – hence the name – this animal has the amazing ability to hover like a helicopter for long periods. On closer inspection, another feature of the hummingbird hawk moth quickly catches the eye: the spiralling curled proboscis, which is as long as the entire animal. The moth uses its proboscis ...

There are many lingering mysteries from the COVID-19 pandemic. For instance, why does SARS-CoV-2, the virus behind the disease, cause severe symptoms in some patients, while many other coronaviruses don’t? And what causes strange symptoms to persist even after the infection has been cleared from a person’s system?   The world may now have the beginning of answers. In a study published today in the journal Proceedings of the National Academy of Sciences, a UCLA-led multidisciplinary research team explores one way that COVID-19 turns the ...
