[Q]: Question: Are perioperative complications after hemiarthroplasty and total shoulder arthroplasty equivalent?
Answer: Multivariate analysis of patients undergoing TSA or HA in the NSQIP database suggests that patient factors-not the procedure being performed-are significant predictors of major complications. Controlling for patient comorbidities, we found no increased risk of perioperative major complications in patients undergoing TSA compared with HA.
[A]: yes

[Q]: Question: Are higher rates of viral suppression with nonnucleoside reverse transcriptase inhibitors compared to single protease inhibitors explained by better adherence?
Answer: A higher proportion of individuals using NNRTI-based regimens had viral suppression when compared to those taking single-PI-containing regimens, and this association was not confounded by higher levels of adherence. These results suggest that improved viral suppression on NNRTI regimens compared to single-PI regimens is more closely associated with regimen potency than higher levels of adherence.
[A]: no

[Q]: Question: Do human embryonic stem cell-derived neural precursor transplants in collagen scaffolds promote recovery in injured rat spinal cord?
Answer: These findings show that transplantation of hESC-NPC in collagen scaffolds into an injured spinal cord may provide a new approach to SCI.
