Introduction: To evaluate the adherence of Austrian obstetricians to national guideline recommendations by investigating data on the current practice of tocolysis regarding indications, timing and monitoring of tocolysis, choice of tocolytics and serious side effects, maintenance tocolysis, support of decision-making and recommendations at patient's discharge from the hospital.
Materials And Methods: 78 obstetric departments in Austria were invited to participate in a nationwide survey between June 5 and August 31 2023 by answering a web-based questionnaire about clinical standards. The survey was conducted approximately one year after implementation of the AWMF Guideline "Prevention and Therapy of Preterm Birth" 015‑025.
Background: Peripapillary blood flow is of diagnostic value in glaucoma.
Material And Methods: We investigated the reproducibility of peripapillary blood flow measurements in healthy individuals and in open-angle glaucoma (OAG) patients with the Nidek laser speckle flowgraphy (LSFG)-NAVI system. Blood flow was calculated as the mean of vascular area (MV), mean of tissue area (MT), and mean of overall flow (MA).
Purpose: Autophagy is an important adaptive process for mechanotransduction, in which Damage-Regulated Autophagy Modulator 1 (DRAM1) has a key function in cell fate determination. This study aimed to analyze the influence of biomechanical loading on DRAM1 expression in periodontal cells and tissues.
Methods: Human periodontal ligament (PDL) fibroblasts were stimulated with different pressure protocols, physiological load and overload, in the presence and absence of autophagy inhibitor 3-methyladenine (3-MA) and compared with untreated cells.
Article Synopsis
- This study compares the image quality and methods for measuring infarct size between a new technique called MT-FIDDLE and the standard bright-blood LGE cardiac MRI in patients who had a heart attack (STEMI).
- The results indicate that MT-FIDDLE provides significantly better subjective image quality, particularly in terms of confidence for infarct segmentation and blood-pool contrast, with a high concordance in infarct volume measurements compared to bright-blood LGE.
- Ultimately, MT-FIDDLE proved to enhance the ability to differentiate between heart injury (myocardial infarction) and surrounding blood, suggesting it could be a superior imaging method for assessing heart damage after a STEMI.
Background: The presence and clinical significance of hepatic tissue alterations as assessed by cardiac magnetic resonance imaging in patients with ST-segment-elevation myocardial infarction (STEMI), are unclear. This study aimed to investigate associations of hepatic T1 patterns with myocardial tissue damage and clinical outcomes in patients suffering from STEMI.
Methods: We analyzed 485 patients with STEMI treated with percutaneous coronary intervention who were enrolled in the prospective MARINA STEMI study (Magnetic Resonance Imaging In Acute ST-Elevation Myocardial Infarction).
