Growth hormone-secreting pituitary adenoma (GHPA), a benign endocrine tumor located in the base of the skull, results in acromegaly. In addition to the mass effect of the tumor itself in the sellar region, GHPA can lead to the overgrowth of almost every organ. Previous findings indicated that the processes underlying acromegaly were partly attributable to hyperactivity of the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis. ⋯ The mechanism of increased trabecula formation may be attributable to GHPA exosome-induced osteoblast proliferation via increased cell viability and DNA replication. We further discovered that exosomal hsa-miR-21-5p plays a distinct role from the GH/IGF-1 axis in these processes. Accordingly, the results of this study provide a novel mechanism whereby GHPA influences distal extremities and a new perspective for treating GHPA.

After publication of our article [1] we were notified that the data presented in the upper row of Fig. 7 was inadvertently the least square mean change from baseline (standard error) at Month 6 rather than the overall average of Month 3 and Month 6. The figure legend and discussion of the data in the text were and are correct. The error was only in the upper row of Fig. 7. The legend for Fig. 7 did not require revision.

To identify the critical nontechnical skills (NTS) required for high performance in variable-resource contexts (VRC). ⋯ This is the first description of the critical nontechnical skills, and associated example behaviors, used by surgeons in a VRC to overcome common challenges to safe and effective surgical patient care. Improvements in the NTS used by surgeons operating in VRCs have the potential to improve surgical care delivery worldwide.
