[EX Q]: Question: 's it just the big kids : both high and low BMI impact bracing success for adolescent idiopathic scoliosis?
Answer: Based on our results, children on either end of the BMI spectrum are more likely to fail brace treatment for scoliosis than their mid-BMI counterparts. In high-BMI patients, this appears to be in large part attributable to an inadequacy of in-brace curve correction as well as to poorer brace compliance, while a low BMI appears to be an independent risk factor for brace failure.
[EX A]: no

[EX Q]: Question: Do delays in Referral and Enrolment Are Associated With Mitigated Benefits of Cardiac Rehabilitation After Coronary Artery Bypass Surgery?
Answer: Strategies for timely access to CR at each phase of the process are important given the negative impact that wait time has on key clinical outcomes. This is relevant because optimizing VO2peak and attendance to CR has been shown to confer a mortality advantage.
[EX A]: yes

[EX Q]: Question: Does gene therapy enhance the antiproliferative effect of radiation in intimal hyperplasia?
Answer: Both IR alone and IR combined with a radiosensitizing agent are effective in attenuating experimental IH. However, combination therapy is synergistic and achieves greater inhibition of VSMC proliferation and may involve selective killing of radioresistant S-phase VSMCs. IR + CD/5-FC represents a novel therapeutic strategy that offers potential for long-term control of IH.
[EX A]:
yes
