Context: Dabigatran is a direct thrombin inhibitor used to reduce the risk of stroke in patients with nonvalvular atrial fibrillation. For patients who present with an acute stroke despite dabigatran therapy, clinical data on the use of intravenous tissue plasminogen activator (IV-tPA) is limited. There is an anticipated increased risk of symptomatic intracranial hemorrhage (sICH) when using IV-tPA in patients on dabigatran therapy. In 2015, the humanized monoclonal antibody fragment idarucizumab was approved for rapid (minutes) reversal of anticoagulant effects of dabigatran. Dabigatran reversal with idarucizumab before administration of IV-tPA might reduce the risk of sICH. We report a case of a 69-year-old stroke patient on dabigatran for paroxysmal atrial fibrillation who presented with an initial National Institutes of Health Stroke Scale (NIHSS) of 12. There was no early evidence of ischemic stroke or hemorrhage on head computed tomography, and coagulation studies implied therapeutic dabigatran levels. After controlling blood pressure, dabigatran was reversed with idarucizumab, and IV-tPA was administrated beginning 197minutes after he was last seen at his baseline. Subsequent brain magnetic resonance imaging showed 2 punctate infarcts in the left temporal lobe and occipital lobe with no evidence of hemorrhage. The patient was discharged with an NIHSS of 1. Telephone follow-up 2 months later indicated that he was at his prestroke baseline, except for a complaint of worsened short-term memory. Idarucizumab reversal of dabigatran may reduce the risk of sICH and should be considered for acute stroke patients arriving in the IV-tPA time window. 
 Question: Which drug can be reversed with idarucizumab?

Ex Output:
dabigatran

Context: It was a comfortable sunny Sunday. I was going to meet an old university friend I hadn't seen for years, and was really excited to hear all his news. My train was running a little late, but that was no big problem - I could text him to say I would be delayed. He would understand. But... where was my mobile phone? I had that familiar sinking feeling. Yes, I'd forgotten it at home. No mobile phone. I'm sure I'm not alone in feeling anxious, _ and worried when I don't have my phone with me. In fact, I know I'm not alone: two-thirds of us experience 'nomophobia', the fear of being out of mobile phone contact. That's according to a study from 2012 which surveyed 1,000 people in the UK about their relationship with mobile phones. It says we check our mobile phones 34 times a day, that women are more 'nomophobic'than men, and that 18-24 year-olds are the most likely to suffer fear of being without their mobiles: 77% of them say they are unable to be apart from their phones for more than a few minutes. Do you have nomophobia ? * You never turn your phone off * You obsessively check for texts, missed calls and emails* You always take your phone to the bathroom with you* You never let the battery run out It's funny to think that around 20 years ago the only people with mobile phones would be businessperson carrying their large, plastic 'bricks'. Of course, these days, mobile phones are everywhere. A UN study from this year said mobile phone subscriptions would outnumber people across the world by the end of 2014. And when there are more phones than people in the world, maybe it's time to ask who really is in charge? Are you in control of your phone, or does your phone control you? So, what happened with my university friend? When I arrived a few minutes late he just laughed and said: "You haven't changed at all - still always late!" And we had a great afternoon catching up, full of jokes and stories, with no interruptions and no nagging desire to check my phone. Not having it with me felt strangely liberating. Maybe I'll leave it at home on purpose next time. 
 Question: Which word is used to describe old mobile phones according to the passage?
