TASK DEFINITION: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
PROBLEM: Question: Is routine post-operative intensive care necessary for children with obstructive sleep apnea at high risk after adenotonsillectomy?
Answer: Our data confirm high rates of AE after AT for high risk patients, however, only 8% suffered a severe AE truly necessitating care in ICU. This outcome was very unlikely if an AE did not occur in PACU. We therefore conclude that routine post-operative ICU care for high risk children may be avoided if prolonged monitoring in the PACU is possible, with admission to ICU reserved for high-risk children with an early AE.

SOLUTION: no

PROBLEM: Question: Is pKCε a negative regulator of PVAT-derived vessel formation?
Answer: PKCε negatively interferes with vessel progenitor differentiation via interaction with PAK-1.

SOLUTION: yes

PROBLEM: Question: Does cXCL12 attract CXCR4+ human metastatic neuroblastoma cells : clinical implications?
Answer: These results show unambiguously that CXCR4 expressed in human metastatic neuroblastoma cells is not functional and do not support the clinical use of CXCR4 antagonists to prevent neuroblastoma metastasis.

SOLUTION:
no
