Question: Does preinjury beta blocker usage affect the heart rate response to initial trauma resuscitation?
Answer: Preinjury beta blockade is associated with a slower presenting heart rate, more bradycardia, less tachycardia, but no difference in mortality or ability to achieve a normal heart rate with resuscitation.
no

Question: Is mRNA expression of RRM1 , ERCC1 and ERCC2 associated with chemosensitivity to cisplatin , carboplatin and gemcitabine in human lung cancer cell lines?
Answer: These in vitro results suggest that further studies are needed to evaluate the expression of the RRM1, ERCC1 and ERCC2 genes as predictive biomarkers for sensitivity to platinum agents and gemcitabine.
no

Question: Is preoperative hypogonadism an independent predictor of high-risk disease in patients undergoing radical prostatectomy?
Answer: In contrast with previous reports, preoperative circulating TT levels were not associated with high-risk PCa. Likewise, hypogonadism did not achieve independent predictor status for high-risk PCa.

no
