Is all health local : state and local planning for physical activity promotion?
These data suggest that despite efforts to increase development and use of stand-alone physical activity plans, most practitioners rely on existing chronic disease- or obesity-related plans to guide their efforts. Barriers to developing stand-alone physical activity plans must be addressed to develop such plans.
Assuming TCDI equipment is used and the STOP protocol is applied, a PSV cutpoint of 200 cm/s is recommended as the threshold for increased TCD surveillance (comparable to a TCD TAMM of 170 cm/s in STOP); a PSV of 250 cm/s is recommended as the cutpoint at which, if confirmed in a second examination, chronic transfusion should be considered. Assuming the STOP scanning protocol is used, PSV is at least as good as TAMM and can be used to select children with SCD for treatment or increased surveillance to prevent first stroke.
