U.S. drug overdose deaths more than quadrupled from 1999 to 2020
2023-09-12
The United States is experiencing its highest overall death rates in more than a century, fueled in part by drug overdose mortality. The origins of the current epidemic are due, at least in part, to a 1986 World Health Organization pronouncement that pain treatment is a universal right. As such, cancer pain treatment guidelines were developed, which included the provision of opioids. In 1995, OxyContin was approved for the management of pain, paving the way for widespread prescription of opioids.

Immunity to COVID-19 reduces contagiousness
2023-09-12
early one in three people exposed to SARS-CoV2 is infected, and as many as two in five with the Omicron variant. In the case of immunity — conferred by vaccination, infection or a combination of the two — this rate drops to one in ten. However, immunity disappears within a few months, confirms a team from the University of Geneva (UNIGE) and Geneva University Hospitals (HUG), after revisiting epidemiological data collected in Geneva. While protection following infection appears to be slightly greater than after vaccination — albeit at the risk of potentially severe ...

US teachers are less satisfied with their pay than most working adults
2023-09-12
Sixty-six percent of U.S. teachers who responded to a new, nationally representative RAND Corporation survey said their base salary was inadequate, compared with 39% of U.S. working adults. These teachers want a $17,000 increase in base pay, on average, to feel that their pay is adequate.
This equates roughly to a 27% pay increase, which is comparable to the estimated gap in pay between teachers and other similarly college-educated workers, also known as the “teacher pay penalty.”
In early 2023, RAND researchers surveyed public-school teachers about how salary and work hours affect ...
Targeted ultrasound can change brain functions for up to an hour after intervention
2023-09-12
The targeted use of ultrasound technology can bring about significant changes in brain function that could pave the way towards treatment of conditions such as depression, addiction, or anxiety, a new study suggests.
Research by neuroscientists at the University of Plymouth explored the impacts of an emerging technique called transcranial ultrasound stimulation (TUS).
Typically, ultrasound examinations involve diffuse broad beams of ultrasound being used to create images while leaving the target tissue unaffected.
However, focusing the beams through TUS can increase the pressure in the target region and change the way ...

Dark matter halos measured around ancient quasars
2023-09-12
At the center of every galaxy is a supermassive black hole. Beyond a certain size, these become active, emitting huge amounts of radiation, and are then called quasars. It is thought these are activated by the presence of massive dark matter halos (DMH) surrounding the galaxy, directing matter towards the center, feeding the black hole. A team including researchers from the University of Tokyo have, for the first time, surveyed hundreds of ancient quasars and found this behavior is very consistent throughout history. This is surprising, as many large-scale processes show variation throughout the ...
Arf1 inhibitors promote the infiltration of cytotoxic T lymphocytes into tumors by affecting lipid metabolism
2023-09-12
In recent years, cancer immunotherapies, represented by immune checkpoint blockade (ICB), have been highly successful and have become an important basis for the future treatment of cancers. However, the absence of tumoral killer T cells and the complexity of tumor microenvironment can both affect the immunotherapeutic efficacy. Therefore, it is urgent to develop novel anti-tumor agents that can effectively promote effector T cell infiltration in tumors.
ADP-ribosylation factor 1 (Arf1) is a member of the Ras small GTPase family and is ...
Intensity-modulated radiation therapy provides long-term benefits to patients with locally advanced lung cancer
