Scientists have discovered how cannabis induces hunger. It may sound hard to believe, but until now no study had mapped out how the drug interacts with cells and hormones to give users the so-called'munchies'. We knew that THC (the psychoactive part of marijuana which induces a'high') interacts with parts of the brain, and that users typically get hungry after using it, but the exact sequence of events remained a mystery. Now researchers at Washington State University have shown that the drug may play with hormones, as well as brain receptors, to induce hunger in a much more complicated fashion than previously thought. Lead author Dr Jon F Davis says the findings are urgently needed, since medical marijuana is being distributed to cancer, HIV and heart disease patients to treat potentially life-threatening appetite loss, but we do not know how it interacts with their bodies or, more importantly, with their diseases.
In 1983, the IBM PC XT debuted with 128K of RAM and a 10MB hard disk. In that same year, the first mobile phone debuted weighing about 2.5 pounds and with a $4,000 price tag. Fast forward to today and the average person unlocks their smartphone 76-80 times a day and relies on it for every aspect of their lives. These amazing pieces of hardware are millions of times more capable than all of NASA's computing power in the 1960s. Now that we have a supercomputer that never leaves people's sides, maybe it's time that we do some more innovation and see how that device can be used for "mobile health".
As part of its latest healthcare-focused venture, Apple has teamed up with Zimmer Biomet on an app designed for knee and hip replacement patients. The app, called mymobility, works with the Apple Watch and iPhone, and it provides patients with guidance before and after their surgeries, tracks their activity, allows surgeons to monitor that activity and lets patients connect with their surgeons through secure messaging. "We believe one of the best ways to empower consumers is by giving them the ability to use their health and activity information to improve their own care," Apple COO Jeff Williams said in a statement. "We are proud to enable knee and hip replacement patients to use their own data and share it with their doctors seamlessly, so that they can participate in their care and recovery in a way not previously possible through traditional in-person visits." Along with the app, Apple and Zimmer Biomet are working on a clinical study that will assess how mymobility impacts patient outcomes and costs.
A drug banned from competitive sports can be found at high doses in some weight-loss and workout supplements -- a finding that researchers say is alarming and could potentially pose health risks. In a new study, researchers analyzed 27 weight-loss and workout supplements now available on the market that listed an ingredient called methylsynephrine on the label. Methylsynephrine, also known as oxilofrine, is a stimulant drug approved in some countries for treating people with low blood pressure, but it is not approved for this use in the United States. The drug is not a legal supplement ingredient, either, and is banned from use in competitive sports. The study found that 14 of the supplements (52 percent) contained methylsynephrine, and of these, close to half (43 percent) contained doses that were equal to or greater than the doses that are typically prescribed for people in places where the drug is legal.
