This study examined the reliability and validity of the 20-meter shuttle test as a predictor of peak VO2 in Edinburgh school children. Thirty-three children (15 boys, 18 girls) performed three shuttle tests and three laboratory treadmill tests of peak VO2. Multiple regression analysis revealed that the prediction of peak VO2 (ml·kg−1·min−1) from shuttle run performance was improved by including skinfold thickness measurements in the prediction models, particularly with the female group. Predictive power was greatest for females when using maximal shuttle speed (kmhr−1) best of three repeat tests and triceps skinfold thickness (mm) (R2 = .85, SEE = 2.4), and for males when using maximal shuttle speed (km·hr−1) best of three repeat tests and the sum of the triceps and subscapular skinfolds (R2 = .68, SEE = 3.23). When using shuttle run performance to predict peak VO2 (ml·kg−1·min−1) in children of this age group, body composition measures must be included in the equation.

Objective To determine the incidence, etiology, and outcome of status epilepticus (SE) in Auckland, New Zealand, using the latest International League Against Epilepsy (ILAE) SE semiological classification. Methods We prospectively identified patients presenting to the public or major private hospitals in Auckland (population = 1.61 million) between April 6, 2015 and April 5, 2016 with a seizure lasting 10 minutes or longer, with retrospective review to confirm completeness of data capture. Information was recorded in the EpiNet database. Results A total of 477 episodes of SE occurred in 367 patients. Fifty‐one percent of patients were aged <15 years. SE with prominent motor symptoms comprised 81% of episodes (387/477). Eighty‐four episodes (18%) were nonconvulsive SE. Four hundred fifty episodes occurred in 345 patients who were resident in Auckland. The age‐adjusted incidence of 10‐minute SE episodes and patients was 29.25 (95% confidence interval [CI] = 27.34‐31.27) and 22.22 (95% CI = 20.57‐23.99)/100 000/year, respectively. SE lasted 30 minutes or longer in 250 (56%) episodes; age‐adjusted incidence was 15.95 (95% CI = 14.56‐17.45) SE episodes/100 000/year and 12.92 (95% CI = 11.67‐14.27) patients/100 000/year. Age‐adjusted incidence (10‐minute SE) was 25.54 (95% CI = 23.06‐28.24) patients/100 000/year for males and 19.07 (95% CI = 16.91‐21.46) patients/100 000/year for females. The age‐adjusted incidence of 10‐minute SE was higher in Māori (29.31 [95% CI = 23.52‐37.14]/100 000/year) and Pacific Islanders (26.55 [95% CI = 22.05‐31.99]/100 000/year) than in patients of European (19.13 [95% CI = 17.09‐21.37]/100 000/year) or Asian/other descent (17.76 [95% CI = 14.73‐21.38]/100 000/year). Seventeen of 367 patients in the study died within 30 days of the episode of SE; 30‐day mortality was 4.6%. Significance In this population‐based study, incidence and mortality of SE in Auckland lie in the lower range when compared to North America and Europe. For pragmatic reasons, we only included convulsive SE if episodes lasted 10 minutes or longer, although the 2015 ILAE SE classification was otherwise practical and easy to use.
