Use of the six-minute walk test poststroke: is there a practice effect?
Findings do not support a practice effect across 2 trials of the 6MWT in individuals within 1 year poststroke. Thus, a practice walk does not appear necessary. Further research is recommended to evaluate the influence of young age, acute stroke, and mild-to-moderate gait deficit on practice effects.
Antibiotic contamination of manure seems to be associated with a variety of changes in bacterial resistance, calling for a prudent use of antibiotics in farm animals.
