Task: Answer Verification
Input (English): Question: Is the GH response to low-dose bolus growth hormone-releasing hormone ( GHRH ( 1-29 ) NH2 ) attenuated in patients with longstanding post-irradiation GH insufficiency?
Answer: The GH response to bolus GHRH(1-29)NH(2) is attenuated in adult long-term survivors of childhood brain tumours. This may reflect direct pituitary damage and/or the loss of the tropic effects of chronic GHRH deficiency.
Output (English): yes
