[Q]: Study author David Kaufman  director of Boston University's Slone Epidemiology Center   noted that ibuprofen and other NSAIDs are among "the most-used medicines in the U.S.
"[But] most NSAID use is over-the-counter "  he  added  "with users deciding what to take without involvement by health care providers."
 Kaufman  downplayed the notion that users might be popping too many NSAIDs to avoid using addictive opioid painkillers.
"My guess "  he  said  "is that while avoidance of opioids may influence prescribing decisions by doctors  it may not affect consumer behavior very much."
Instead   Kaufman  believes some consumers may simply decide to take an excessive number of pills â regardless of label instructions. But that behavior is "potentially modifiable with better education of users " he added.

[Q]: More than half the seats in Catalonia ' s 135 - seat parliament will be occupied by pro - independence parties .  Spanish Prime Minister Mariano Rajoy ' s own right - wing People ' s Party alone looks to lose 60 % of their seats  . But there ' s one person who most certainly won ' t be sitting in one of those seats   even though — thanks to a YouTube video that ’  s  been viewed almost a million times —  he  most likely did more than a little to help Thursday ' s overwhelming pro - independence win . “ The situation on Oct . 1 changed everything  ” Albano Dante Fachin told BuzzFeed News as  he  cleaned out  his  office inside Catalonia ’ s parliament building on Thursday night . Oct . 1 was the day Catalonia held a referendum on whether to separate from Spain   a move the Spanish government had tried desperately to prevent . Police and other armed forces were sent into the region to try to keep people from the polls   but Catalan leaders still declared a victory for the independence movement . After the vote   the Spanish senate triggered Article 155 of the country ’ s constitution   which stripped the region of its autonomy . Thursday night ’ s snap election was called by Rajoy after he used his new authority to dissolve the Catalan parliament and imprison eight politicians . Catalan President Carles Puigdemont fled to Brussels   where he has been campaigning via livestream and social media . It ’ s been a hectic election full of vicious identity politics   disorienting misinformation   and increasing paranoia among Catalans about Spanish governmental overreach . Seven major parties were vying for seats on Thursday . But for most voters   instead of thinking of things in terms of right and left   it was a decision between a pro - Catalan independence voting bloc and a rival bloc of parties that have campaigned on Catalonia remaining a part of Spain . For Catalans   it came down to a race between the left - wing progressive party Esquerra Republicana on the “ independentista ” side and economic liberal party Ciudadanos on the unionist   a victory for either deciding the region ’ s future relationship with Madrid . There was one party   though   that tried to stay out of the independence debate . Podemos   a left - wing anti - corruption party that was founded in 2014 out of Spain ’ s Occupy Wall Street equivalent   resisted choosing a side . But thanks to Fachin   its now - former general secretary   it ended up having one of the biggest impacts on this week ’ s vote . Fachin shocked Catalans last week after he announced via YouTube video that he was resigning from Podemos and voting for a pro - independence party . The video has currently been watched over 800   000 times and   according to Spanish media   it ’ s the most watched video of the election . His decision to vote for an independence party to protest Spain ’ s crackdown on the region   and not because he agreed with the results of the Catalan referendum   became a lightning rod on social media .
