Little is known about influencing factors of function and quality of life during multicomponent cardiac rehabilitation. Methods: From October 2013 to July 2015, patients with elective transcatheter aortic valve implantation and a subsequent inpatient cardiac rehabilitation were enrolled in the prospective cohort multicentre study. Frailty-Index (including cognition, nutrition, autonomy and mobility), Short Form-12 (SF-12), six-minute walk distance (6MWD) and maximum work load in bicycle ergometry were performed at admission and discharge of cardiac rehabilitation. The relation between patient characteristics and improvements in 6MWD, maximum work load or SF-12 scales were studied univariately and multivariately using regression models. Results: One hundred and thirty-six patients (80.6 +/- 5.0 years, 47.8\% male) were enrolled. 6MWD and maximum work load increased by 56.3 +/- 65.3 m (p < 0.001) and 8.0 +/- 14.9 watts (p < 0.001), respectively. An improvement in SF-12 (physical 2.5 +/- 8.7, p = 0.001, mental 3.4 +/- 10.2, p = 0.003) could be observed. In multivariate analysis, age and higher education were significantly associated with a reduced 6MWD, whereas cognition and obesity showed a positive predictive value. Higher cognition, nutrition and autonomy positively influenced the physical scale of SF-12. Additionally, the baseline values of SF-12 had an inverse impact on the change during cardiac rehabilitation. Conclusions: Cardiac rehabilitation can improve functional capacity as well as quality of life and reduce frailty in patients after transcatheter aortic valve implantation. An individually tailored therapy with special consideration of cognition and nutrition is needed to maintain autonomy and empower octogenarians in coping with challenges of everyday life.}, language = {en} } @article{Warschburger2017, author = {Warschburger, Petra}, title = {Jugendliche und junge Erwachsene mit Adipositas}, series = {Die Rehabilitation : Zeitschrift f{\"u}r Praxis und Forschung in der Rehabilitation}, volume = {57}, journal = {Die Rehabilitation : Zeitschrift f{\"u}r Praxis und Forschung in der Rehabilitation}, number = {5}, publisher = {Thieme}, address = {Stuttgart}, issn = {0034-3536}, doi = {10.1055/s-0043-107930}, pages = {295 -- 302}, year = {2017}, abstract = {Hauptziel Adipositas ist eine der Hauptindikationen in der Kinder- und Jugend-Rehabilitation.

However, the challenging combination of high training volumes and academic demands may impede youth athletes' cognitive and academic performances. Thus, the aims of this study were to examine the effects of a 1-year sport-specific training and/or physical education on physical fitness, body composition, cognitive and academic performances in youth athletes and their non-athletic peers. Methods: Overall, 45 prepubertal fourth graders from a German elite sport school were enrolled in this study. Participating children were either youth athletes from an elite sports class (n = 20, age 9.5 ± 0.5 years) or age-matched peers from a regular class (n = 25, age 9.6 ± 0.6 years). Over the 1-year intervention period, the elite sports class conducted physical education and sport-specific training (i.e., gymnastics, swimming, soccer, bicycle motocross [BMX]) during school time while the regular class attended physical education only. Of note, BMX is a specialized form of cycling that is performed on motocross tracks and affords high technical skills. Before and after intervention, tests were performed for the assessment of physical fitness (speed [20-m sprint], agility [star agility run], muscle power [standing long jump], flexibility [stand-and-reach], endurance [6-min-run], balance [single-leg stance]), body composition (e.g., muscle mass), cognitive (d2-test) and academic performance (reading [ELFE 1-6], writing [HSP 4-5], calculating [DEMAT 4]). In addition, grades in German, English, Mathematics, and physical education were documented. Results: At baseline, youth athletes showed better physical fitness performances (p < 0.05; d = 0.70-2.16), less relative body fat mass, more relative skeletal muscle mass (p < 0.01; d = 1.62-1.84), and similar cognitive and academic achievements compared to their non-athletic peers. Athletes' training volume amounted to 620 min/week over the 1-year period while their peers performed 155 min/week. After the intervention, significant differences were found in 6 out of 7 physical fitness tests (p < 0.05; d = 0.75-1.40) and in the physical education grades (p < 0.01; d = 2.36) in favor of the elite sports class. No significant between-group differences were found after the intervention in measures of body composition (p > 0.05; d = 0.66-0.67), cognition and academics (p > 0.05; d = 0.40-0.64). Our findings revealed no significant between-group differences in growth rate (deltas of pre-post-changes in body height and leg length). Discussion: Our results revealed that a school-based 1-year sport-specific training in combination with physical education improved physical fitness but did not negatively affect cognitive and academic performances of youth athletes compared to their non-athletic peers.

The input frequency approach predicts that object relative clauses with inanimate heads (e.g., the pullover that the man is scratching) are comprehended earlier and more accurately than those with an animate head (e.g., the man that the boy is scratching). In contrast, the structural intervention approach predicts that object relative clauses with two full NP arguments mismatching in number (e.g., the man that the boys are scratching) are comprehended earlier and more accurately than those with number-matching NPs (e.g., the man that the boy is scratching). These approaches were tested in two steps. First, we ran a corpus analysis to ensure that object relative clauses with number-mismatching NPs are not more frequent than object relative clauses with number-matching NPs in child directed speech. Next, the comprehension of these structures was tested experimentally in 3-, 4-, and 5-year-olds respectively by means of a color naming task. By comparing the predictions of the two approaches within the same participant groups, we were able to uncover that the effects predicted by the input frequency and by the structural intervention approaches co-exist and that they both influence the performance of children on transitive relative clauses, but in a manner that is modulated by age. These results reveal a sensitivity to animacy mismatch already being demonstrated by 3-year-olds and show that animacy is initially deployed more reliably than number to interpret relative clauses correctly. In all age groups, the animacy mismatch appears to explain the performance of children, thus, showing that the comprehension of frequent object relative clauses is enhanced compared to the other conditions. Starting with 4-year-olds but especially in 5-year-olds, the number mismatch supported comprehension—a facilitation that is unlikely to be driven by input frequency. Once children fine-tune their sensitivity to verb agreement information around the age of four, they are also able to deploy number marking to overcome the intervention effects. This study highlights the importance of testing experimentally contrasting theoretical approaches in order to characterize the multifaceted, developmental nature of language acquisition.}, language = {en} }
