Modifying gut bacteria could be a treatment option for some of the symptoms associated with the widespread disease polycystic ovary syndrome (PCOS), according to a recent study by San Diego State University researchers in collaboration with investigators from the University of California, San Diego. The study found that changes in gut bacteria are strongly associated with obesity and signs of diabetes in a mouse model that mimics PCOS.

The best time to identify signs of obstructive sleep apnea may not be at night while snoozing in bed but, instead, while sitting in the dentist's chair.

Gun deaths is a disingenuous term in the modern American political climate, because it includes suicides and assumes a lack of access to guns would eliminate the 60 percent of handgun deaths that are suicides, or guns used by criminals.

Gun ownership does not seem to lead to more murders, and murders are the real concern. There, we have a Handgun Paradox, where even in states like California, which make it more difficult to get a concealed weapons permit, gun ownership has boomed but murders have plummeted. 

Yet if a trickle down effect is acceptable economics, it might also work in guns. 

Avalanches are the primary hazard for winter back country recreational trekkers and cause numerous deaths and injuries annually. 

These snowy adventures have grown in popularity, leading people to forget that just because you paid a professional guide does not mean there is no risk. A new study in Wilderness and Environmental Medicine explored the risk of avalanche accidents and found a strong correlation with great risk of avalanches; group size. Traveling in groups of four or more people carried a higher relative avalanche risk than for individuals or groups of two.

Antidepressants, commonly used to treat anxiety, pain and other disorders, may play a role in dental implant failure, according to a new pilot study which found that the use of antidepressants increased the odds of implant failure by four times. 

While these drugs are often used to manage mood and emotions, a side effect decreases the regulation of bone metabolism, which is crucial to the healing process.

Each year of antidepressant use doubled the odds of failure.

Green tea is touted for its many health benefits as a powerful antioxidant, but experiments in a laboratory mouse model of inflammatory bowel disease suggest that consuming green tea along with dietary iron may actually lessen green tea's benefits.

"If you drink green tea after an iron-rich meal, the main compound in the tea will bind to the iron," said Matam Vijay-Kumar, assistant professor of nutritional sciences, Penn State. "When that occurs, the green tea loses its potential as an antioxidant. In order to get the benefits of green tea, it may be best to not consume it with iron-rich foods." Iron-rich foods include red meat and dark leafy greens, such as kale and spinach. According to Vijay-Kumar, the same results also apply to iron supplements.
