Input: Consider Input: Question: Is preoperative prolonged steroid use associated with intraoperative blood transfusion in noncardiac surgical patients?
Answer: The effect of prolonged steroid use on bleeding, if any, thus seems likely to be small and is probably of limited clinical consequence. In contrast, corticosteroid use augments the risk of both systemic and wound infections.

Output: no


Input: Consider Input: Question: Is low serum bilirubin concentration a predictor of chronic kidney disease?
Answer: Our study demonstrated that serum total bilirubin concentration could be a novel risk factor for the progression of CKD, defined as eGFR <60 ml/min/1.73 m(2), in the general population.

Output: yes


Input: Consider Input: Question: Is telling adolescents a parent dying?
Answer: Families inform adolescents about the progression of a parent's terminal illness in characteristic ways that remain fairly consistent throughout the illness, and are aimed at easing the adolescents' burden and distress. The families engaged in the process of disclosure in one of four ways: measured telling, skirted telling, matter-of-fact telling, and inconsistent telling. These results will inform the development of interventions that assist families with disclosure and are tailored to each family's communication style.


Output: yes
