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: Hello, Listeners. Welcome to Henton Hospital Radio. Before our music programme at four, I'm going to repeat some of our hospital rules. The hospital can sleep 800 patients. There're 8 beds in each ward . The visiting hours are in the afternoon from 2:30 to 3:30 and in the evening from 7:00 to 8:00. But remember only two people can see you at the same time. Sorry about that, but you can see what would happen if we didn't have these rules. The other rules are about our hours. We start quite early---you might not be used to that. We wake you at 6 o'clock, and breakfast is at 8 o'clock, lunch is at noon. There's tea at 3:30 and supper is at 6 o'clock. You can see the non-smoking sign---we don't allow smoking in the wards. I'm sure you understand why. However, if you do need to smoke, there are some smoking rooms where it is allowed. You will find the radio switch on the wall near your bed, with your own headphones, if you want to listen. It's our own hospital radio wishing you a quick recovery. 
 Question: Who do you think the listeners might be?

Ex Output:
patients.

Context: Something roared like thunder. The earth shook a little and we heard the rat-a-tat-tat of gunfire. "Father!" Hassan cried. We sprung to our feet and raced out of the living room. "Father! What's that sound? Hassan screamed, his hands outstretched toward Ali. Ali wrapped his arms around us. A white light flashed and lit the sky in silver. It flashed again and was followed by rapid sharp sounds of gunfire. "They're hunting ducks." Ali said in a hoarse voice. "They hunt ducks at night, you know." Don't be afraid. A siren went off in the distance. Somewhere glass broke and someone shouted. I heard people on the street, jolted from sleep and probably still in their pajamas, with ruffled hair and puffy eyes. Hassan was crying. Ali pulled him close, clutched him with tenderness. We stayed huddled that way until the early hours of the morning. The shootings and explosions had lasted less than an hour, but they had frightened us badly, because none of us had ever heard gunshots in the streets. They were foreign sounds to us then. The generation of Afghan children whose ears would know nothing but the sounds of bombs and gunfire was not yet born. Huddled together in the dining room and waiting for the sun to rise, none of us had any notion that a way of life had ended. The end came when Russian tanks were rolling into the very same streets where Hassan and I played, bringing the death of the Afghanistan I knew and marking the start of a still ongoing era of bloodletting. Just before sunrise, Baba's car peeled into the driveway. His door slammed shut and his running footsteps pounded the stairs. Then he appeared in the doorway and I saw something on his face. Something I didn't recognize right away because I'd never seen it before: fear. "Amir! Hassan!" He cried as he ran to us, opening his arms wide. "They blocked all the roads and the telephone didn't work. I was so worried!" We let him wrap us in his arms and, for a brief moment, I was glad about whatever had happened that night.
