Journal ArticleDOI
Association between ultrasound measurements of muscle thickness, pennation angle, echogenicity and skeletal muscle strength in the elderly
TL;DR: Measurement of muscle thickness, especially of musculus vastus medialis, by M-US is a reliable, bedside method for monitoring the extent of sarcopenia, and multiple regression analysis revealed that thickness ofmusculus vastu medialis had the best correlation with MVC in the elderly.
Journal ArticleDOI
Cardiac magnetic resonance postcontrast T1 time is associated with outcome in patients with heart failure and preserved ejection fraction.
Julia Mascherbauer,Beatrice A. Marzluf,Caroline Tufaro,Stefan Pfaffenberger,Alexandra Graf,Paul Wexberg,Adelheid Panzenböck,Johannes Jakowitsch,Christine Bangert,Daniela Laimer,Catharina Schreiber,Gültekin Karakus,Martin Hülsmann,Richard Pacher,Irene M. Lang,Gerald Maurer,Diana Bonderman +16 more
TL;DR: In the present preliminary study, cardiac magnetic resonance postcont contrast T1 time is associated with prognosis in HFPEF, suggesting postcontrast T1 as possible biomarker for HFP EF.
Journal ArticleDOI
Impact of tricuspid regurgitation on survival in patients with chronic heart failure: unexpected findings of a long-term observational study
Stephanie Neuhold,Martin Huelsmann,Elisabeth Pernicka,Alexandra Graf,Diana Bonderman,Christopher Adlbrecht,Thomas Binder,Gerald Maurer,Richard Pacher,Julia Mascherbauer +9 more
TL;DR: While TR was significantly related with excess mortality in mild to moderate CHF, it provided no additive value in advanced disease when compared with established risk factors.
Journal ArticleDOI
Human retinal pigment epithelium (RPE) transplantation: outcome after autologous RPE-choroid sheet and RPE cell-suspension in a randomised clinical study
Christiane I. Falkner-Radler,Ilse Krebs,Carl Glittenberg,Boris Povazay,Wolfgang Drexler,Alexandra Graf,Susanne Binder +6 more
TL;DR: The anatomical and functional outcome after both RPE transplantation techniques was comparable, and intrastructural irregularities of the sheet assessed using SD-OCT might explain the rather limited visual gain in otherwise successful sheet transplants.
Journal ArticleDOI
Survival of direct resin restorations in posterior teeth within a 19-year period (1996–2015): A meta-analysis of prospective studies
Florian Beck,Stefan Lettner,Alexandra Graf,B. Bitriol,N. Dumitrescu,Peter Bauer,Andreas Moritz,Andreas Schedle +7 more
TL;DR: There is still a big need for clinical studies lasting longer than 5 years, as failure rates of composite restorations in posterior teeth increases with longer observation periods, which suggests a patient selection in regard to availability and dental awareness.
