Health Research: First human trials of drug to prevent death due to severe blood loss ♦ Cancer-causing parasite may accelerate wound healing ♦ Researchers measure gait to reduce falls from glaucoma

First human trials of drug to prevent death due to severe blood loss Researchers will launch the first Phase 1 human trials of a drug — derived from the female hormone estrogen — that may help patients with severe bleeding survive long enough to get to appropriate medical care. The drug may have a profound effect on an individual’s ability to survive major blood loss.
Marijuana use more than doubles from 2001 to 2013; increase in use disorders too The estimated prevalence of adults who used marijuana in the past year more than doubled in the United States between 2001 and 2013 to 9.5 percent, according to a new article. As is the case with alcohol, many individuals can use marijuana without becoming addicted. However, the clear risk for marijuana use disorders among users (approximately 30 percent) suggests that as the number of U.S. users grows, so will the numbers of those experiencing problems related to such use.
Cancer-causing parasite may accelerate wound healing A cancer-causing, parasitic worm could help patients recover from their wounds, say researchers. They report that the parasite could live for decades in the human body, and would have an incentive to keep its host healthy while chewing away at its cells.
How diet may affect the progression of multiple sclerosis Dietary fatty acids affect the development and progression of autoimmune chronic-inflammatory diseases such as multiple sclerosis. In a collaborative study, researchers now found that long-chain fatty acids promote the development and propagation of CNS reactive immune cells in the intestinal wall. On the contrary, short-chain fatty acids promote the development and propagation of regulatory cells in the immune system.

Researchers measure gait to reduce falls from glaucoma Researchers have developed a way to carefully analyze a person's gait with sensors, an innovation that could lead to reduced falls and injuries in people with glaucoma, the second leading cause of blindness in the United States
