Health Research: Key mechanism that causes neuropathic pain found ♦ Marijuana users substitute alcohol at 21 ♦ Higher vitamin D doses needed to restore healthy levels in overweight blacks

Marijuana users substitute alcohol at 21 A recent study looked at marijuana and alcohol use in people between the ages of 18 and 24. It's probably not surprising that the results show a drastic increase in alcohol consumption in people just over 21; after all, that's the minimum legal age to drink. What an economist-researcher found remarkable is that, at the same age, there was an equally dramatic drop in marijuana use.
Age-related self-destruction of cells makes kidney prone to injury As advances in medicine allow individuals to live longer, people are facing unique age-related health challenges. As they age, organs such as the kidneys become more susceptible to injury, and their ability to self-repair is decreased. Researchers have found a cellular signal that causes kidney cells to die, making the kidneys prone to injury.
Higher vitamin D doses may be needed to restore healthy levels in overweight blacks The current recommended minimum daily dose of vitamin D is not sufficient to restore healthy vitamin D levels in overweight or obese black.
Life expectancy substantially lower with combination of diabetes, stroke or heart attack In an analysis that included nearly 1.2 million participants and more than 135,000 deaths, mortality associated with a history of diabetes, stroke or heart attack was similar for each condition, and the risk of death increased substantially with each additional condition a patient had.
Key mechanism that causes neuropathic pain found A biological process called endoplasmic reticulum stress appears to play a key role in causing neuropathic pain, according to a new study. The discovery could eventually lead to new therapeutics for controlling chronic pain associated with trauma, diabetes, shingles, multiple sclerosis or other conditions that cause nerve damage
