A1 - Gerß, Joachim A1 - Rosenbaum, Dieter T1 - Physical activity and health-related quality of life in pediatric cancer patients following a 4-week inpatient rehabilitation program JF - Supportive Care in Cancer N2 - Abstract Purpose Chronic health conditions and impaired quality of life are commonly experienced in childhood cancer survivors. While rehabilitation clinics support patients in coping with the disease, studies evaluating an inpatient rehabilitation program on promoting physical activity (PA) and health-related quality of life (HRQoL) are missing. Methods A 4-week inpatient rehabilitation program was prospectively evaluated. One hundred fifty patients with leukemia or lymphoma (N = 86), brain tumors (N = 38), and sarcomas (N = 26) were enrolled on average 17 months after cessation of acute medical treatment. PA amount and cadence (indicating the intensity of walking activity) using the StepWatch™ 3 Activity Monitor and HRQoL global and physical well-being scores using the KINDL® questionnaire were assessed before, immediately after, and 6 and 12 months following the program and analyzed using multiple linear mixed models. Results Significant effects on PA were only found at 12-month follow-up for amount and cadence variables (all p < 0.05). While leukemia and lymphoma patients revealed the highest PA level throughout the study, rehabilitation effects were more pronounced for cadence variables in brain tumor and sarcoma patients. The rehabilitation program had immediate (t = 4.56, p < 0.001) and sustainable effects on HRQoL global scores (6-month follow-up, t = 4.08, p < 0.001; 12-month follow-up, t = 3.13, p < 0.006). Conclusions Immediate and sustainable increases in HRQoL indicate that a 4-week rehabilitation program is beneficial for improving psychosocial well-being, while the significant increase in PA levels could be related to general recovery as well. The lack of a control group hampers the evaluation of the rehabilitation program on promoting PA levels in pediatric cancer patients.

Die Ergebnisse für die kritische Temperatur, das Verhalten im überkritischen Bereich und den Einfluss von Vorverformungen werden in Diagrammen in Abhängigkeit von den Steifigkeitsparametern angegeben. N2 - The stability of circular rings with radial elastic support under a uniform temperature rise is investigated by classical theory of stability, by geometrically non-linear theory and by tests. The results for the critical temperature, the behaviour in the post-critical range and the influence of initial irregularities are presented in graphs as functions of two stiffness parameters.

Der Ringraum zwischen Rohr und Liner wird häufig mit Dämmer verfüllt. Die Standsicherheit muss für die Lebensdauer des sanierten Bauwerks unter den während der Sanierungsarbeiten und beim Betrieb des Abwasserkanals herrschenden Bedingungen gewährleistet sein. Das bedeutet, dass konservative Annahmen bezüglich des System- und Belastungsverhaltens zu treffen sind. Für einige wichtige Lastfälle (hydrostatischer Druck mit Auftrieb, Eigenlasten, Temperaturänderungen usw.) werden Lösungsansätze diskutiert und Durchschlagbeiwerte alpha D angegeben. Von besonderer Bedeutung für die Sicherheitsnachweise ist der richtige Ansatz der Vorverformungen: Sie müssen sowohl die Verformungen des Kanals repräsentieren als auch stabilitätstheoretischen Erkenntnissen entsprechen. N2 - Defect sewers can be repaired by drawing in flexible liners or by lining parts of the circumference. The gap between pipe and liner is usually grouted. The structural safety of the renovated sewer must be ensured during the construction works and under long-term service conditions. This means, that conservative assumptions for the system and the load behaviour must be introduced into the analysis. For some important load cases (hydrostatic pressure with buoyancy, dead loads, temperature change etc.) solution methods are discussed and snap through coefficients alpha D are presented. A true statement of the imperfections is very important far the safety analysis: The imperfections have to represent the deflections of the sewer and must be in accordance with the stability theory.
