Respondents with complete SCI performed a max test on an arm ergometer.\n\nResults: Exercisers with complete SCI reported a significantly higher perceived exercise mastery (P = 0.002) and exercisers with incomplete SCI reported a significantly lower perceived exercise mastery (P = 0.012) than nonexercisers. Exercisers in both groups reported a higher perceived fitness (complete SCI, P = 0.016; incomplete SCI, P = 0.004) than nonexercisers. A regression analysis showed that exercising versus nonexercising (exercise status) was the only variable that contributed 4SC-202 ic50 to the variance in perceived exercise

mastery for persons with complete SCI (P<0.001). For persons with incomplete injury, exercise status and exercise hours per week contributed to the variance in perceived exercise mastery.\n\nConclusion: selleck chemical Although perceived fitness is associated with exercise in the whole SCI population, perception of exercise mastery is negatively related to exercise in persons with incomplete SCI, in contrast to those with complete lesions.

“Appropriate use criteria

(AUC) for single-photon emission computed tomography myocardial perfusion images (SPECT-MPI) were developed to address the growth of cardiac imaging studies. However, these criteria have not been vigorously validated. We sought to determine the rate of abnormal stress SPECT-MPI studies and subsequent revascularization procedures as categorized by AUC.\n\nWe retrospectively examined 280 patients A1155463 who underwent stress SPECT-MPI and categorized these studies as appropriate,

inappropriate, or uncertain based on AUC. Data regarding subsequent angiography and revascularization within 6 months after stress SPECT-MPI were collected from the electronic medical record.\n\n280 patients met the inclusion criteria (mean age 67.3 +/- A 11.4 years, 36 % female). When categorized by AUC, 62.9 % (N = 176) of stress SPECT-MPI were considered appropriate, 13.6 % (N = 38) uncertain, and 23.6 % (N = 66) inappropriate. Appropriate stress SPECT-MPI studies were more likely to have intermediate or high risk results than uncertain or inappropriate studies [40 % (N = 71) vs. 21 % (N = 8) and 18 % (N = 12), respectively; P = 0.008)]. Appropriate studies were associated with an increased rate of coronary angiography [14 % (N = 25)] compared to the uncertain (0 %) and inappropriate [3 % (N = 2)] studies (P = 0.003). There was also an increased rate of revascularization after appropriate studies [9 % (N = 16)] compared to the uncertain (0 %) and inappropriate (0 %) studies (P = 0.006).\n\nAppropriate stress SPECT-MPI studies are more likely to result in abnormal results requiring subsequent revascularization compared to inappropriate and uncertain stress studies.
