Opinion: What happens to health care if Alberta separates? - Edmonton Journal

From chicken soup and honey to vitamin C and wet hair, Dr. Guy Choshen examines common cold remedies, separating those that may ease symptoms from those that lack scientific evidence and explaining when medical attention is neededynet|As winter approaches, the familiar box of tissues returns to the table, along with a flood of well-meaning advice on how to ward off a cold. Every household has at least one traditional remedy passed down through generations: hot chicken soup when a runny nose starts, a glass of orange juice to "boost the immune system" and the familiar warning at the door: "You're not going outside with wet hair! "But there can be a considerable gap between grandmother's wisdom and what modern medicine tells us. Dr. Guy Choshen, head of Internal Medicine Department B at Meir Medical Center, part of Israel's Clalit Health Services, examines the most common home remedies and myths surrounding colds, distinguishing between what works, what does no harm and what simply isn't true. GalleryWhich remedies actually work and which just have good publicity?

Bioengineer.org news storyFor millions of people living with HIV, antiretroviral therapy has transformed a once-fatal infection into a manageable chronic condition. Yet the very drugs that suppress the virus can carry quiet costs, and one of the most insidious is bone loss. Tenofovir disoproxil fumarate, or TDF, has been a cornerstone of HIV treatment worldwide for two decades, prized for its potency, durability, and low cost. But a growing body of evidence has linked TDF exposure to measurable reductions in bone mineral density, raising an increasingly urgent clinical question: once bone has been lost on a TDF-based regimen, can it be recovered? A new prospective cohort study, published in BMC Infectious Diseases, offers some of the most detailed longitudinal evidence to date that the answer, for many patients, is yes. The research team enrolled 223 virologically suppressed men living with HIV who had low bone mineral density while taking TDF-based antiretroviral therapy.

The new treatment kills off a sub-group of fat cells. (Jian Fan/iStockphoto/Getty Images) Early clinical trials into a new fat reduction treatment have reported promising results, and the treatment takes a more unusual approach: Rather than shrinking fat cells, as most weight loss strategies do, it safely and naturally kills them off. The drug here is CBL-514, which is administered via injection. As well as proving effective at reducing subcutaneous fat (just below the skin), there's evidence it can also reduce visceral fat (stored deeper around the organs). According to the team behind the trials, CBL-514 and its unconventional strategy have the potential to reduce fat in key areas of the body – with further benefits that come with weight loss likely to follow. "We expect that patients will be pleased by the cosmetic effects, such as the flatter stomach that can come with subcutaneous fat loss," says endocrinologist Timothy Garvey, from the University of Alabama at Birmingham, who headed up the trial.
