Hintergrund: Dehntrainings sind eine Maßnahme der betrieblichen Gesundheitsförderung (BGF) für Büroangestellte zur Prävention von muskuloskeletalen Erkrankungen (MSE). Sie können zu Beweglichkeitszuwächsen führen und auf psychischer Ebene entspannen. Ziel der Studie war es, ein standardisiertes und individualisiertes Dehntraining am Gerät, das „five-Business“, auf MSE, Lebensqualität und Beweglichkeit zu untersuchen. Dies ist eine Zusammenfassung der international publizierten Ergebnisse.
Methodik: In diese Untersuchung wurden 252 Proband(innen) eingeschlossen, 156 in die Interventionsgruppe (IG), 96 in die Kontrollgruppe (KG). Die IG absolvierte für 12 Wochen 22–24 Trainingseinheiten am „five-Business“, möglichst zweimal wöchentlich. Die Datenerhebung erfolgte mittels sportmotorischer bzw. Range-of-motion(ROM)-Tests, dem Nordic Questionnaire (NQ) und dem SF-36-Fragebogen in Form einer Prä-Post-Untersuchung.
Ergebnisse: Nach der Intervention gaben im NQ signifikant weniger Proband(innen) der IG Beschwerden im oberen Rücken (p < 0,001) im Vergleich zur KG an; keine signifikanten Unterschiede wurden bei Beschwerden im Nacken, Schultern, Hüfte und dem unteren Rücken gefunden. Der mit dem SF-36 erhobene allgemeine Gesundheitszustand und die gesundheitsbezogene Lebensqualität haben sich (nach subjektiven Angaben) signifikant verbessert (Summenscore IG: p = 0,005). In den ROM-Tests waren die Prä-Post-Differenzen bei IG-Proband(innen) in der Sagittalebene (Finger-Boden-Abstand und Retroflexion; p < 0,001) und im modifizierten Schultertest nach Janda auf der linken Seite (p = 0,003) signifikant größer.
Diskussion: Trotz des in Zeitdauer und Häufigkeit relativ geringen Trainingsaufwandes wurden sowohl auf körperlicher als auch auf psychischer Ebene relevante Verbesserungen erzielt, so dass das „five-Business“-Dehntraining als BGF-Maßnahme empfohlen werden kann.
In German, the subject usually precedes the object (SO order), but, under certain discourse conditions, the object is allowed to precede the subject (OS order). This paper focuses on main clauses in which either the subject or a discourse-given object occurs in clause-initial position. Two acceptability experiments show that OS sentences with a given object are generally acceptable, but the precise degree of acceptability varies both with the object‘s referential form (demonstrative objects leading to higher acceptability than other types of objects) and with formal properties of the subject (pronominal subjects leading to higher acceptability than non-pronominal subjects). For SO sentences, acceptability was reduced when the object was a d-pronoun, which contrasts with the high acceptability of OS sentences with a d-pronoun object. This finding was explored in a third acceptability experiment comparing d-pronouns in subject and object function. This experiment provides evidence that a reduction in acceptability due to a prescriptive bias against d-pronouns is suspended when the d-pronoun occurs as object in the prefield. We discuss the experimental results with respect to theories of German clause structure that claim that OS sentences with different information-structural properties are derived by different types of movement.
Patients with ataxia-telangiectasia (A-T) suffer from progressive cerebellar ataxia, immunodeficiency, respiratory failure, and cancer susceptibility. From a clinical point of view, A-T patients with IgA deficiency show more symptoms and may have a poorer prognosis. In this study, we analyzed mortality and immunity data of 659 A-T patients with regard to IgA deficiency collected from the European Society for Immunodeficiencies (ESID) registry and from 66 patients with classical A-T who attended at the Frankfurt Goethe-University between 2012 and 2018. We studied peripheral B- and T-cell subsets and T-cell repertoire of the Frankfurt cohort and survival rates of all A-T patients in the ESID registry. Patients with A-T have significant alterations in their lymphocyte phenotypes. All subsets (CD3, CD4, CD8, CD19, CD4/CD45RA, and CD8/CD45RA) were significantly diminished compared to standard values. Patients with IgA deficiency (n = 35) had significantly lower lymphocyte counts compared to A-T patients without IgA deficiency (n = 31) due to a further decrease of naïve CD4 T-cells, central memory CD4 cells, and regulatory T-cells. Although both patient groups showed affected TCR-ß repertoires compared to controls, no differences could be detected between patients with and without IgA deficiency. Overall survival of patients with IgA deficiency was significantly diminished. For the first time, our data show that patients with IgA deficiency have significantly lower lymphocyte counts and subsets, which are accompanied with reduced survival, compared to A-T patients without IgA deficiency. IgA, a simple surrogate marker, is indicating the poorest prognosis for classical A-T patients. Both non-interventional clinical trials were registered at clinicaltrials.gov 2012 (Susceptibility to infections in ataxia-telangiectasia; NCT02345135) and 2017 (Susceptibility to Infections, tumor risk and liver disease in patients with ataxia-telangiectasia; NCT03357978)
