Basistests Suisse Sport Test Konzept: Validierung einer sportmotorischen Basistestbatterie für den Schul- und Nachwuchssport

Physical fitness can be evaluated in competitive and school sports with different field tests under different conditions and goals. To produce valid results, a field test must be practical and reach high standards of test criteria (objectivity, reliability, validity). The purpose of this study was to investigate the test criteria and the practicability of a group of field tests called «SUISSE Sport Test Konzept Basis Feldtestbatterie». For 20-m sprint, ventral trunk muscle test, standing long jump, 2-kg medicine ball shot, obstacle course and cooper-test, test quality and practicability were evaluated. 221 children and adolescents from competitive sports and different school levels took part in the study. According to school level, they were divided into 3 groups (P: 7–11.5 y, S1: 11.6–15.5 y, S2: 15.6–21.8 y). Objectivity was tested for time or distance measurement in all tests as well as for error rating in obstacle test. For reliability measurement, 162 subjects performed the field tests twice within a few weeks. For validity results of standing long jump were compared with counter movement jump performance on a force plate. Correlation analysis was performed and level of significance was set for p < 0.05. For accuracy standard error was calculated. All tests achieved sufficient to excellent objectiv - ity with correlation-coefficient (r) lying between 0.85 and 0.99. Reliability was very good (r = 0.84–0.97). In cooper- and trunk test, reliability was higher for athletes than for pupils (trunk test: r = 0.95 vs. r = 0.62, cooper-test: r = 0.90 vs. r = 0.78). In those tests the reliability decreases with increasing age (cooper-test: P: r = 0.84, S1: r = 0.69, S2: r = 0.52; trunk-test: P: r = 0.69, S1: r = 0.71; S2: r = 0.39). Validity for standing long jump was good (r = 0.75–0.86). The standard error of the mean was between 4–8%, with the exception for cooper-test (athletes: 6%, pupils: 11%) and trunk test (athletes: 14%, pupils: 46%). The results show that the evaluated group of field tests is a practicable, objective and reliable tool to determine physical skills in young athletes as well as in a scholar setting over a broad age range. Most of the tests achieved the test criteria with the grades good to excellent. The lower coefficient of reliability for cooper- and trunk test by the pupils could be explained by motivational problems in this setting. For up to 20 subjects, a tester can accomplish the tests within 3 h. Finally, age-dependent grades were elaborated

Der Capability-Ansatz in der Gesundheitsförderung: Ansatzpunkte für eine Neuausrichtung der Ungleichheitsforschung

Gesundheitliches Wohlergehen geht unmittelbar auf das aktive Zutun von Personen und Kollektiven zurück. Zugleich wird gesundheitsrelevantes Handeln nur unter der Berücksichtigung der jeweiligen physischen und sozialen Kontexte zu verstehen und zu beeinflussen sein. Dementsprechend wird hier eine Ausrichtung der modernen Gesundheitsforderung auf die gesundheitsrelevanten Ressourcen und Handlungsspielräume der Menschen vorgeschlagen. Hierfür sind theoretische Grundlagen erforderlich, die die Fragen der sozialen Ungleichheit mit den praktischen Zugängen des Empowerment und der Partizipation schlüssig verbinden. Die Autoren stellen dazu den Capability-Approach (CA) von Amartya Sen vor und ergänzsa diesen mit Erkenntnissen aus der Kapital-Interaktionstheorie von Pierre Bourdieu. Beide Ansätze beleuchten Grundfragen der sozialen Ungleichheit und können mit den Leitkonzepten der Ottawa-Charta fruchtbar verbunden werden. Sie liefern damit auch Anleitungen für neue Forschungsrichtungen zur Untersuchung der komplexen Wechselwirkungen von sozialen Kontexten und gesundheitsrelevantem Handeln.

Japanese-US common-arm analysis of paclitaxel plus carboplatin in advanced non-small-cell lung cancer: a model for assessing population-related pharmacogenomics

PURPOSE To explore whether population-related pharmacogenomics contribute to differences in patient outcomes between clinical trials performed in Japan and the United States, given similar study designs, eligibility criteria, staging, and treatment regimens. METHODS We prospectively designed and conducted three phase III trials (Four-Arm Cooperative Study, LC00-03, and S0003) in advanced-stage, non-small-cell lung cancer, each with a common arm of paclitaxel plus carboplatin. Genomic DNA was collected from patients in LC00-03 and S0003 who received paclitaxel (225 mg/m(2)) and carboplatin (area under the concentration-time curve, 6). Genotypic variants of CYP3A4, CYP3A5, CYP2C8, NR1I2-206, ABCB1, ERCC1, and ERCC2 were analyzed by pyrosequencing or by PCR restriction fragment length polymorphism. Results were assessed by Cox model for survival and by logistic regression for response and toxicity. Results Clinical results were similar in the two Japanese trials, and were significantly different from the US trial, for survival, neutropenia, febrile neutropenia, and anemia. There was a significant difference between Japanese and US patients in genotypic distribution for CYP3A4*1B (P = .01), CYP3A5*3C (P = .03), ERCC1 118 (P < .0001), ERCC2 K751Q (P < .001), and CYP2C8 R139K (P = .01). Genotypic associations were observed between CYP3A4*1B for progression-free survival (hazard ratio [HR], 0.36; 95% CI, 0.14 to 0.94; P = .04) and ERCC2 K751Q for response (HR, 0.33; 95% CI, 0.13 to 0.83; P = .02). For grade 4 neutropenia, the HR for ABCB1 3425C-->T was 1.84 (95% CI, 0.77 to 4.48; P = .19). CONCLUSION Differences in allelic distribution for genes involved in paclitaxel disposition or DNA repair were observed between Japanese and US patients. In an exploratory analysis, genotype-related associations with patient outcomes were observed for CYP3A4*1B and ERCC2 K751Q. This common-arm approach facilitates the prospective study of population-related pharmacogenomics in which ethnic differences in antineoplastic drug disposition are anticipated.
