  abstract  = {Hintergrund: Circa ein Drittel der Patientinnen und Patienten mit fortgeschrittenen Krebserkrankungen ist von psychischen Komorbidit{\"a}ten betroffen und circa die H{\"a}lfte weist eine psychische Belastung im klinisch signifikanten Bereich auf. Zur psychotherapeutischen Behandlung dieser Patientengruppe stehen unterschiedliche psychotherapeutische Interventionen zur Verf{\"u}gung. Die CALM-Therapie, eine manualisierte Kurzintervention im Einzelsetting, ist eine dieser Interventionen. Hier bilden vier Module, welche auf den wichtigsten Anliegen und Belastungsfaktoren von Patientinnen und Patienten mit fortgeschrittenen Krebserkrankungen basieren, den inhaltlichen Rahmen. Ziel: Die Treatment Integrity beschreibt das Maß, inwieweit eine psychotherapeutische Intervention wie vorgesehen umgesetzt wurde. F{\"u}r eine fundierte Interpretation psychotherapeutischer Interventionseffekte sind Kenntnisse {\"u}ber die Treatment Integrity entscheidend. Die vorliegende Arbeit untersuchte Teilaspekte der Treatment Integrity durchgef{\"u}hrter CALM-Therapien im Vergleich zu durchgef{\"u}hrten konventionellen psychoonkologischen Therapien, um einen Beitrag zu einer fundierten Interpretation von Interventionseffekten der CALM-Therapie zu leisten. Methoden: Transkriptionen von zwei CALM-Therapien und zwei Therapien einer konventionellen psychoonkologischen Intervention wurden anhand einer qualitativen Inhaltsanalyse nach P. Mayring untersucht. Im Zentrum stand hierbei ein selbst entwickeltes Kategoriensystem zur Analyse des gesamten Textmaterials. Zus{\"a}tzlich wurden Auff{\"a}lligkeiten bez{\"u}glich Ansprachen von Themenbereichen der CALM-Module unsystematisch beobachtet. Ergebnisse: Die Inhalte der untersuchten CALM-Therapien bezogen sich durchschnittlich zu 99,54\% und die der konventionellen psychoonkologischen Therapien durchschnittlich zu 98,71\% auf die Themenbereiche der CALM-Module. Die ermittelten Werte f{\"u}r einzelne Therapiesitzungen lagen f{\"u}r CALM-Sitzungen zwischen 98,12\% und 100\% und f{\"u}r Sitzungen der konventionellen psychoonkologischen Therapie zwischen 96,20\% und 100\%. Unsystematisch beobachtete Auff{\"a}lligkeiten zeigten, dass die Themenbereiche der CALM-Module zum Teil sehr spezifisch durch die CALM-Therapeutinnen und -Therapeuten angesprochen und vernetzt wurden. Schlussfolgerung: Unter Ber{\"u}cksichtigung von methodischen Grenzen zeigte sich bez{\"u}glich des Anteils von Themenbereichen der CALM-Module innerhalb der beiden untersuchten Therapiegruppen kein maßgeblicher Unterschied. Zus{\"a}tzlich liefert die vorliegende Arbeit Hinweise f{\"u}r einen spezifischen therapeutischen Umgang mit den Themenbereichen der CALM-Module innerhalb der untersuchten CALM-Therapien. Um ermittelte Interventionseffekte der CALM-Therapie fundiert interpretieren zu k{\"o}nnen, sollten zuk{\"u}nftige Untersuchungen unterschiedliche Umgangsweisen von Therapeutinnen und Therapeuten der beiden Therapiegruppen mit den Themenbereichen der CALM-Module genauer in den Blick nehmen.},

  abstract  = {Background: Animal models have implicated an integral role for coagulation factors XI (FXI) and XII (FXII) in thrombus formation and propagation of ischemic stroke (IS). However, it is unknown if these molecules contribute to IS pathophysiology in humans, and might be of use as biomarkers for IS risk and severity. This study aimed to identify predictors of altered FXI and FXII levels and to determine whether there are differences in the levels of these coagulation factors between acute cerebrovascular events and chronic cerebrovascular disease (CCD). Methods: In this case-control study, 116 patients with acute ischemic stroke (AIS) or transitory ischemic attack (TIA), 117 patients with CCD, and 104 healthy volunteers (HVs) were enrolled between 2010 and 2013 at our University hospital. Blood sampling was undertaken once in the CCD and HV groups and on days 0, 1, and 3 after stroke onset in patients with AIS or TIA. Correlations between serum FXI and FXII levels and demographic and clinical parameters were tested by linear regression and analysis of variance. Results: The mean age of AIS/TIA patients was 70 ± 12. Baseline clinical severity measured with NIHSS and Barthel Index was 4.8 ± 6.0 and 74 ± 30, respectively. More than half of the patients had an AIS (58\%). FXI levels were significantly correlated with different leukocyte subsets (p < 0.05). In contrast, FXII serum levels showed no significant correlation (p > 0.1). Neither FXI nor FXII levels correlated with CRP (p > 0.2). FXII levels were significantly higher in patients with CCD compared with those with AIS/TIA (mean ± SD 106 ± 26\% vs. 97 ± 24\%; univariate analysis: p < 0.05); these differences did not reach significance in multivariate analysis adjusted for sex and age. FXI levels did not differ significantly between study groups. Sex and age were significantly associated with FXI and/or FXII levels in patients with AIS/TIA (p < 0.05). In contrast, no statistical significant influence was found for treatment modality (thrombolysis or not), pre-treatment with platelet inhibitors, and severity of stroke. Conclusions: In this study, there was no differential regulation of FXI and FXII levels between disease subtypes but biomarker levels were associated with patient and clinical characteristics. FXI and FXII levels might be no valid biomarker for predicting stroke risk.},

  abstract  = {Aims The aim of this study was to determine whether the Joint European Societies guidelines on secondary cardiovascular prevention are followed in everyday practice. Design A cross-sectional ESC-EORP survey (EUROASPIRE V) at 131 centres in 81 regions in 27 countries. Methods Patients (<80 years old) with verified coronary artery events or interventions were interviewed and examined ≥6 months later. Results A total of 8261 patients (females 26\%) were interviewed. Nineteen per cent smoked and 55\% of them were persistent smokers, 38\% were obese (body mass index ≥30 kg/m2), 59\% were centrally obese (waist circumference: men ≥102 cm; women ≥88 cm) while 66\% were physically active <30 min 5 times/week. Forty-two per cent had a blood pressure ≥140/90 mmHg (≥140/85 if diabetic), 71\% had low-density lipoprotein cholesterol ≥1.8 mmol/L (≥70 mg/dL) and 29\% reported having diabetes. Cardioprotective medication was: anti-platelets 93\%, beta-blockers 81\%, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers 75\% and statins 80\%. Conclusion A large majority of coronary patients have unhealthy lifestyles in terms of smoking, diet and sedentary behaviour, which adversely impacts major cardiovascular risk factors. A majority did not achieve their blood pressure, low-density lipoprotein cholesterol and glucose targets. Cardiovascular prevention requires modern preventive cardiology programmes delivered by interdisciplinary teams of healthcare professionals addressing all aspects of lifestyle and risk factor management, in order to reduce the risk of recurrent cardiovascular events.},

  abstract  = {Background: Designing treatment strategies for unruptured giant intracranial aneurysms (GIA) is difficult as evidence of large clinical trials is lacking. We examined the outcome following surgical or endovascular GIA treatment focusing on patient age, GIA location and unruptured GIA. Methods: Medline and Embase were searched for studies reporting on GIA treatment outcome published after January 2000. We calculated the proportion of good outcome (PGO) for all included GIA and for unruptured GIA by meta-analysis using a random effects model. Results: We included 54 studies containing 64 study populations with 1,269 GIA at a median follow-up time (FU-T) of 26.4 months (95\% CI 10.8-42.0). PGO was 80.9\% (77.4-84.4) in the analysis of all GIA compared to 81.2\% (75.3-86.1) in the separate analysis of unruptured GIA. For each year added to patient age, PGO decreased by 0.8\%, both for all GIA and unruptured GIA. For all GIA, surgical treatment resulted in a PGO of 80.3\% (95\% CI 76.0-84.6) compared to 84.2\% (78.5-89.8, p = 0.27) after endovascular treatment. In unruptured GIA, PGO was 79.7\% (95\% CI 71.5-87.8) after surgical treatment and 84.9\% (79.1-90.7, p = 0.54) after endovascular treatment. PGO was lower in high quality studies and in studies presenting aggregate instead of individual patient data. In unruptured GIA, the OR for good treatment outcome was 5.2 (95\% CI 2.0-13.0) at the internal carotid artery compared to 0.1 (0.1-0.3, p < 0.1) in the posterior circulation. Patient sex, FU-T and prevalence of ruptured GIA were not associated with PGO. Conclusions: We found that the chances of good outcome after surgical or endovascular GIA treatment mainly depend on patient age and aneurysm location rather than on the type of treatment conducted. Our analysis may inform future research on GIA.},

  abstract  = {Background: Population-based data, which continuously monitors time trends in stroke epidemiology are limited. We investigated the incidence of pathological and etiological stroke subtypes over a 16 year time period. Methods: Data were collected within the Erlangen Stroke Project (ESPro), a prospective, population-based stroke register in Germany covering a total study population of 105,164 inhabitants (2010). Etiology of ischemic stroke was classified according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria. Results: Between January 1995 and December 2010, 3,243 patients with first-ever stroke were documented. The median age was 75 and 55\% were females. The total stroke incidence decreased over the 16 year study period in men (Incidence Rate Ratio 1995-1996 vs. 2009-2010 (IRR) 0.78; 95\% CI 0.58-0.90) but not in women. Among stroke subtypes, a decrease in ischemic stroke incidence (IRR 0.73; 95\% CI 0.57-0.93) and of large artery atherosclerotic stroke (IRR 0.27; 95\% CI 0.12-0.59) was found in men and an increase of stroke due to small artery occlusion in women (IRR 2.33; 95\% CI 1.39-3.90). Conclusions: Variations in time trends of pathological and etiological stroke subtypes were found between men and women that might be linked to gender differences in the development of major vascular risk factors in the study population.},

  abstract  = {Background: Dose requirements of erythropoietin-stimulating agents (ESAs) can vary considerably over time and may be associated with cardiovascular outcomes. We aimed to longitudinally assess ESA responsiveness over time and to investigate its association with specific clinical end points in a time-dependent approach. Methods: The German Diabetes and Dialysis study (4D study) included 1,255 diabetic dialysis patients, of whom 1,161 were receiving ESA treatment. In those patients, the erythropoietin resistance index (ERI) was assessed every 6 months during a median follow-up of 4 years. The association between the ERI and cardiovascular end points was analyzed by time-dependent Cox regression analyses with repeated ERI measures. Results: Patients had a mean age of 66 ± 8.2 years; 53\% were male. During follow-up, a total of 495 patients died, of whom 136 died of sudden death and 102 of infectious death. The adjusted and time-dependent risk for sudden death was increased by 19\% per 5-unit increase in the ERI (hazard ratio, HR = 1.19, 95\% confidence interval, CI = 1.07-1.33). Similarly, mortality increased by 25\% (HR = 1.25, 95\% CI = 1.18-1.32) and infectious death increased by 27\% (HR = 1.27, 95\% CI = 1.13-1.42). Further analysis revealed that lower 25-hydroxyvitamin D levels were associated with lower ESA responsiveness (p = 0.046). Conclusions: In diabetic dialysis patients, we observed that time-varying erythropoietin resistance is associated with sudden death, infectious complications and all-cause mortality. Low 25-hydroxyvitamin D levels may contribute to a lower ESA responsiveness.},

The aim of the present work is to provide the stepwise proceedings of the development and current version of the harmonized MeDALL-Core Questionnaire (MeDALL-CQ) used prospectively in 11 European birth cohorts. Methods: The harmonization of questions was accomplished in 4 steps: (i) collection of variables from 14 birth cohorts, (ii) consensus on questionnaire items, (iii) translation and back-translation of the harmonized English MeDALL-CQ into 8 other languages and (iv) implementation of the harmonized follow-up. Results: Three harmonized MeDALL-CQs (2 for parents of children aged 4-9 and 14-18, 1 for adolescents aged 14-18) were developed and used for a harmonized follow-up assessment of 11 European birth cohorts on asthma and allergies with over 13,000 children. Conclusions: The harmonized MeDALL follow-up produced more comparable data across different cohorts and countries in Europe and will offer the possibility to verify results of former cohort analyses. Thus, MeDALL can become the starting point to stringently plan, conduct and support future common asthma and allergy research initiatives in Europe.},

  abstract  = {Introduction Multidisciplinary, complex rehabilitation interventions are an important part of the treatment of chronic diseases. However, little is known about the effectiveness of routine rehabilitation interventions within the German healthcare system. Due to the nature of the social insurance system in Germany, randomised controlled trials examining the effects of rehabilitation interventions are challenging to implement and scarcely accessible. Consequently, alternative pre-post designs can be employed to assess pre-post effects of medical rehabilitation programmes. We present a protocol of systematic review and meta-analysis methods to assess the pre-post effects of rehabilitation interventions in Germany. Methods and analysis The respective study will be conducted within the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A systematic literature review will be conducted to identify studies reporting the pre-post effects (start of intervention vs end of intervention or later) in German healthcare. Studies investigating the following disease groups will be included: orthopaedics, rheumatology, oncology, pulmonology, cardiology, endocrinology, gastroenterology and psychosomatics. The primary outcomes of interest are physical/mental quality of life, physical functioning and social participation for all disease groups as well as pain (orthopaedic and rheumatologic patients only), blood pressure (cardiac patients only), asthma control (patients with asthma only), dyspnoea (patients with chronic obstructive pulmonary disease only) and depression/anxiety (psychosomatic patients only). We will invite the principal investigators of the identified studies to provide additional individual patient data. We aim to perform the meta-analyses using individual patient data as well as aggregate data. We will examine the effects of both study-level and patient-level moderators by using a meta-regression method. Ethics and dissemination Only studies that have received institutional approval from an ethics committee and present anonymised individual patient data will be included in the meta-analysis. The results will be presented in a peer-reviewed publication and at research conferences. A declaration of no objection by the ethics committee of the University of W{\"u}rzburg is available (number 20180411 01).},

  abstract  = {HINTERGRUND. In zahlreichen epidemiologischen Studien, so auch in der bev{\"o}lkerungsbasierten W{\"u}rzburger Kohortenstudie STAAB (STAdien A und B der Herzinsuffizienz) mit prim{\"a}ren kardiologischen Fragestellungen, wird die K{\"o}rperzusammensetzung mittels bioelektrischer Impedanzanalyse (BIA) gemessen. In einer Pilotstudie wurden das Messprotokoll und die Reproduzierbarkeit der Messungen {\"u}berpr{\"u}ft. Außerdem wurde untersucht, wie sich die Verletzung bestimmter Protokollvorschriften (Messung am n{\"u}chternen Probanden im Ruhezustand) verzerrend auf die Messwerte auswirken. METHODEN. Die Probanden (16 M{\"a}nner, 18 Frauen) waren vollj{\"a}hrig, hatten keine mit dem Protokoll unvertr{\"a}glichen Erkrankungen oder Medikationen und erteilten ihre schriftliche informierte Einwilligung. In sechs konsekutiven BIA-Messungen wurden mittels Seca® mBCA 515 fettfreie Masse, Muskelmasse, Fettmasse, Fettanteil, Gesamtk{\"o}rperwasser und extrazellul{\"a}res Wasser unter verschiedenen Bedingungen bestimmt. Zun{\"a}chst wurden unter den vorgeschriebenen Standardbedingungen zwei direkt aufeinander folgende Messungen durchgef{\"u}hrt, zwischen denen die Probanden das Ger{\"a}t verließen. Die dritte Messung erfolgte unmittelbar nach dem Trinken von 500mL Mineralwasser, die vierte nach 20-30min Wartezeit. Anschließend unterzogen sich die Probanden unterzogen einer k{\"o}rperlichen Belastung (Laufen im Stand, Springen, Kniebeugen) bis zum Einsetzen einer deutlichen Schweißproduktion. Die f{\"u}nfte BIA-Messung erfolgte im unmittelbaren Anschluss an die Belastung, die sechste nach weiteren 5min Ruhepause. ERGEBNISSE. Die beiden unter Standardbedingungen durchgef{\"u}hrten Messungen lieferten bei den Probanden jeweils fast identische Werte. Die Wasseraufnahme wurde vom Ger{\"a}t bei M{\"a}nnern nur marginal (+100g), bei Frauen gar nicht als solche registriert. Vielmehr wurde eine signifikante Zunahme der Fettmasse angezeigt (M{\"a}nner +300g, Frauen +500g, siehe Abbildung). Die Fehlzuordnung des aufgenommenen Wassers verschob sich nach der Wartezeit nur geringf{\"u}gig. Nach der k{\"o}rperlichen Belastung wurde bei den M{\"a}nnern eine gestiegene Fettmasse gemessen (+400g, siehe Abbildung), die sich nach der kurzen Ruhepause wieder reduzierte (-300g), w{\"a}hrend sich die angezeigte K{\"o}rperwassermasse genau gegenl{\"a}ufig verhielt. Bei den Frauen waren die Ver{\"a}nderungen unter Belastung und nach der Ruhepause geringf{\"u}gig. Die Verlaufsprofile der Geschlechter unterschieden sich in allen Messvariablen signifikant (Interaktionstest). SCHLUSSFOLGERUNG. Die Messwerte des BIA-Ger{\"a}ts sind unter den definierten Standardbedingungen gut reproduzierbar. Die experimentellen Ver{\"a}nderungen der Protokollstandards simulierten allt{\"a}glich vorkommende Einflussfaktoren wie Wasserzufuhr oder k{\"o}rperliche Belastung kurz vor der Untersuchung. Die Ergebnisse zeigen, dass die Nichteinhaltung der Standards zu messbaren Verzerrungen f{\"u}hren. Dies ist umso gravierender, da die Verzerrungen in den vom Ger{\"a}t angezeigten Messwerten physikalisch nicht ihren kausalen Ursachen entsprechen und zudem bei den Geschlechtern verschieden ausgepr{\"a}gt sind. Vor dem Hintergrund dieser Ergebnisse sollten bei der epidemiologischen Interpretation statistischer Zusammenh{\"a}nge von BIA-Werten mit anderen Messgr{\"o}ßen auch immer die m{\"o}glichen Auswirkungen fehlerhafter Zuordnung von K{\"o}rperanteilen kritisch gepr{\"u}ft und er{\"o}rtert werden.},

  abstract  = {Onkologische Patienten sowie klinische Forscher zeigen zunehmendes Interesse an Yogainterventionen als komplement{\"a}res Therapieverfahren zur Behandlung psychischer und k{\"o}rperlicher Beschwerden. Kurzzeitige Effekte von Yogatherapien auf die h{\"a}ufig krebsassoziierten Symptome Angst, Depressivit{\"a}t und Fatigue wurden in zahlreichen Studien untersucht. Die Ergebnisse der Untersuchungen legen nahe, dass Tumorpatienten unmittelbar nach einer Yogaintervention eine Verbesserung der genannten Symptome erleben. Allerdings ist bisher unzureichend untersucht, ob ein R{\"u}ckgang von Angst, Depressivit{\"a}t und Fatigue langfristig besteht. Ziel der Studie war es daher, nachhaltige Ver{\"a}nderungen von Angst, Depressivit{\"a}t und Fatigue bei Tumorpatienten im Rahmen einer achtw{\"o}chigen Yogaintervention zu untersuchen. Wir nahmen an, dass Angst, Depressivit{\"a}t und Fatigue sechs Monate nach einer Yogaintervention genauso niedrig wie unmittelbar nach der Intervention sind und sich signifikant von den Ausgangswerten vor der Intervention unterscheiden. Außerdem sollte untersucht werden, wie viele Teilnehmer die Yogapraxis nach einer Yogaintervention fortf{\"u}hren und ob sich dies auf die Zielparameter auswirkt. Durch eine klinische Studie im Pr{\"a}-Post-Design wurden die Hypothesen gepr{\"u}ft. Dazu wurden Daten von 58 Teilnehmern mit unterschiedlichen Tumorerkrankungen vor, unmittelbar nach und sechs Monate nach einer achtw{\"o}chigen Gentle Hatha- Yogaintervention mittels standardisierter psychologischer Frageb{\"o}gen gesammelt. Die Mehrheit der Studienteilnehmer war weiblich (90\%) und wies anamnestisch eine Mammakarzinom-Erkrankung auf (55\%). Die Ergebnisse legen nahe, dass Angst und Fatigue zwischen Interventionsende und sechs Monaten sp{\"a}ter leicht zunahmen, wohingegen depressive Symptome stabil blieben. Im Vergleich zu den Ausgangswerten vor der Intervention waren Angst, Depressivit{\"a}t und Fatigue sechs Monate nach Interventionsende signifikant reduziert. Ein halbes Jahr nach Beendigung der Yogaintervention gaben 69\% der Teilnehmer an, weiterhin Yoga zu praktizieren. Befragungen zeigten, dass die Teilnehmer subjektiv von der Yogapraxis profitierten. Die fortgef{\"u}hrte Yogapraxis stand jedoch nicht mit der Auspr{\"a}gung von Angst, Depressivit{\"a}t und Fatigue zum Follow-up-Zeitpunkt in Zusammenhang. Die Ergebnisse deuten darauf hin, dass Tumorpatienten langfristig von einer Verbesserung von Angst, Depressivit{\"a}t und Fatigue im Rahmen einer Yogatherapie profitieren k{\"o}nnten. Ein kausaler Zusammenhang zwischen Yogatherapie und der gefundenen Verbesserung sechs Monate nach Therapieende konnte jedoch durch die fehlende Kontrollbedingung nicht belegt werden. In Zukunft sollten große randomisierte kontrollierte Studien die vermutete Kausalit{\"a}t untersuchen.},
