Association between acute alcohol use, firearm-involved suicide

JAMA Network Open

2023-03-29

(Press-News.org) About The Study: This study of suicide decedents who had consumed alcohol prior to their death suggests that, as alcohol consumption increased, the probability of a firearm-involved suicide increased until a certain blood alcohol concentration, at which point the probability started to decrease. The findings suggest that interventions targeting heavy alcohol use may aid in efforts to reduce the suicide mortality rate, particularly suicides involving a firearm.

Drug overdose fatalities among US older adults has quadrupled over 20 years, UCLA research finds

2023-03-29

Overdose mortality among people age 65 and older quadrupled over 20 years, suggesting the need for greater mental health and substance use disorder policies addressed at curbing the trend, a new research paper finds. The deaths stemmed from both suicides and accidental overdoses, with nearly three-fourths of the unintended fatalities involving illicit drugs such as synthetic opioids like fentanyl, heroin, cocaine, and methamphetamines. Prescription opioids, antidepressants, benzodiazepines, antiepileptics and sedatives were used in 67% of intentional overdoses. “The dramatic rise in overdose fatalities among adults over 65 years of ...

Deep ocean currents around Antarctica headed for collapse, study finds

2023-03-29

The deep ocean circulation that forms around Antarctica could be headed for collapse, say scientists. Such decline of this ocean circulation will stagnate the bottom of the oceans and generate further impacts affecting climate and marine ecosystems for centuries to come. The results are detailed in a new study coordinated by Scientia Professor Matthew England, Deputy Director of the ARC Centre for Excellence in Antarctic Science (ACEAS) at UNSW Sydney. The work, published today in Nature, includes lead author Dr. Qian Li—formerly from UNSW and now ...

Diminishing health benefits of living in cities for children and teens

IMPERIAL COLLEGE LONDON PRESS RELEASE Under STRICT EMBARGO until: Wednesday 29 March 2023 16:00 BST / 11:00 ET Peer-reviewed / Observational study / People Diminishing health benefits of living in cities for children and teens The advantages of living in cities for children and adolescents’ healthy growth and development are shrinking across much of the world, according to a new global analysis of trends in child and adolescent height and body mass index (BMI) led by Imperial College London and published in Nature. The research, by a global consortium of more than 1500 researchers and physicians, analysed height ...

Memorial Sloan Kettering scientists identify potential new strategy against metastasis

2023-03-29

MSK researchers identified a key role for the STING signaling pathway in preventing dormant metastatic cancer cells from progressing to active metastases. Treating laboratory mice with a STING activator helped eliminate lingering metastatic cells and stop the development of aggressive tumors. The study suggests further investigation of STING activation as a new approach to prevent cancer from recurring or spreading to other organs after successful treatment of a primary tumor. A team of scientists at the Sloan Kettering Institute have identified the STING cellular signaling pathway as a key player in keeping dormant cancer cells from progressing ...

You can find the flow – and scientists can measure it

2023-03-29

You know when you’ve found the flow. You experience it when you are doing something that engages you so fully that time seems to fly by. Maybe it's a job, or something completely different, like chess or computer games or football or shovelling snow. But flow is not just an expression that people use. It has been a concept used by psychologists for almost 50 years, because finding the flow can be useful for people. “Finding the flow zone can be important when teachers have to adapt their instruction. If we find the flow, we’ve also found the right level for the students,” says Hermundur Sigmundsson, a professor in the Department of Psychology ...

Transportation noise increases risk for suicides

2023-03-29

Mental health disorders affect nearly one billion people worldwide and are a leading cause of suicide. In Switzerland, it is estimated that about 1.4 million people are affected by mental health issues and that approximately 1,000 people take their lives every year. Environmental factors such as air pollution or noise have been linked to adverse health effects such as cardiovascular diseases and general well-being. However, robust evidence on the effects of transportation noise on mental health disorders remains scarce. For the first time, ...

Magnon-based computation could signal computing paradigm shift

2023-03-29

Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption. A magnon corresponds to the specific amount of energy required to change the magnetization of a material via a collective excitation called a spin wave. Because they interact with magnetic fields, magnons can be used to encode and transport data without electron flows, which involve energy loss through heating (known as Joule heating) of the conductor ...

New ways to protect food crops from climate change and other disruptions

2023-03-29

“There’s no doubt we can produce enough food for the world’s population - humanity is strategic enough to achieve that. The question is whether - because of war and conflict and corruption and destabilization - we do,” said World Food Programme leader David Beasley in an interview with Time magazine earlier this year. Indeed, projections show that we are not on track to achieve Sustainable Development Goal 2 of Zero Hunger by 2030. As climate and security crises continue to destabilise our food sources, researchers are taking a critical look not just at how we produce food - but at the entire systems behind ...

Immune Checkpoint Inhibitor Antitumor Response: Decoding Molecular Mechanisms

2023-03-29

Immune checkpoint inhibitors (ICIs) are widely sought after for the treatment of different types of cancers. Unfortunately, only 20–30% patients with cancer respond to ICI treatment. Although the factors that influence the positive or negative response to ICI treatment are poorly understood, the strength of the ICIs’ antitumor response by TILs is thought to play a key role. Hence, investigating the antitumor response induced by ICIs might provide insights into their underlying mechanism. It is known that CD8+ tumor-infiltrating T-lymphocytes (TILs) are the primary effector cells that lead ...
