Input: Consider Input: Question: Does transparent and open discussion of errors increase malpractice risk in trauma patients?
Answer: A transparent discussion of errors, complications, and deaths does not appear to lead to an increased risk of lawsuit.

Output: no

Input: Consider Input: Question: Are lobar microbleeds associated with a decline in executive functioning in older adults?
Answer: Lobar microbleeds, a marker of cerebral amyloid angiopathy, are associated with an accelerated rate of executive function decline. The presence of cerebral amyloid angiopathy may be an important source of cognitive decline in aging. Future work should examine how cerebral amyloid angiopathy interacts with neurodegenerative processes, such as Alzheimer's disease.

Output: yes

Input: Consider Input: Question: Are brain lesions most often reversible in acute thrombotic thrombocytopenic purpura?
Answer: Posterior reversible encephalopathy syndrome is the most common brain imaging abnormality in severe manifestations of thrombotic thrombocytopenic purpura. Large infarctions and hemorrhage are infrequent. Consequently, abnormal brain neuroimaging does not seem to impact patient outcome, and full neurologic recovery is possible even in comatose patients with extensive brain abnormalities on MRI.
Output: yes
