Moderate to severe malnourishment in the first year of life but with good rehabilitation thereafter leaves a legacy of lower social status in adulthood and a widening income gap relative to healthy controls (Pediatrics 2012;130:e1-7, doi:10.1542/peds.2012-0073). The differences, say the researchers, are partly attributable to cognitive impairment in those who were malnourished.

In a controlled laboratory study, a surgeon tied 90 knots using FiberWire through an arthroscopic cannula. Half the knots had a static “surgeon’s base” and half a Tennessee slider base. Three shortcut techniques were compared: rethreading, and two types of knot “flipping.” Compared with Tennessee knots, surgeon’s knots had a lower incidence of slippage and catastrophic failure. Shortcut techniques did not affect the properties of the surgeon’s knots but led to increased problems with the Tennessee knots (American Journal of Sports Medicine 2012;40:1572-7, doi:10.1177/0363546512446676).

Nurses, as well as doctors, are living up to the current banner of “keep calm and carry on,” with resilience being …
