The study team describe their own plunge into the social networking stream, where they found that they could see what people were talking about, who was talking and why they were posting about those issues. "We were really interested in understanding more about how the public uses social media to discuss important topics," said senior author Dr. Raina Merchant, of Penn Medicine Social Media and Health Innovation Lab at the University of Pennsylvania in Philadelphia. She and her colleagues write in JAMA Cardiology that over 300 million people use Twitter to communicate with each other, but it was unknown whether researchers could separate messages of substance from noise and ultimately analyze those messages. For the new study, they searched approximately 10 billion English-language Twitter posts - known as tweets - originating in the U.S. between July 2009 and February 2015 for messages about five cardiovascular and related diseases: high blood pressure, heart attack, cardiac arrest, heart failure and diabetes. The search terms included heart attack, coronary attack, diabetes, mellitus, heart arrest and heart failure.

Los Angeles County public health officials and LGBT advocates are urging gay and bisexual men to get meningitis vaccinations, citing a recent outbreak of potentially deadly meningococcal disease that is disproportionately affecting men who have sex with men. There have been 17 confirmed cases of invasive meningococcal disease confirmed in the county so far this year, including 12 in the last two months, Jeffrey Gunzenhauser, the interim director of the L.A. County Department of Public Health, said Thursday. Eight have been among gay or bisexual men, including seven within the last two months, he said. "In L.A. County, since May, the number of these infections among men, most of whom have identified themselves as gay or bisexual, is substantially more than we would normally expect during this time of the year," Gunzenhauser said at a news conference at the Los Angeles LGBT Center. "This is of great concern."
"Come and Get It" singer Selena Gomez entered rehab to treat anxiety and depression, Us Weekly reported Wednesday.

Olympic track legend Usain Bolt, whose infectious mid-race smile made for a breakout meme of the Rio Olympics this summer, had another chance to show off his comedy chops recently in a new commercial for the Jamaican telecom Digicel. The subtly branded video features the Jamaica-born sprinter jamming out in a studio, lip-syncing an original auto-tuned holiday ballad about "sprint-sprint-sprinting through [his] Christmas list," among other things. In a FaceTime conversation with Mashable, the easy-going star talked about his meme-dom fame, his unlikely source of fitness motivation and what his success has meant for his sport's popularity in his home country and abroad. Bolt, who regularly updates his various social media accounts with playful family anecdotes, pictures with celebrity friends and luxury spoils, clearly knows his way around a meme. But the wildfire popularity of his Olympics smile shot this summer still surprised him.
