"Can you answer questions, Flobi?": Interactionally defining a robot’s competence as a fitness instructor

Süssenbach L, Pitsch K, Berger I, Riether N, Kummert F. "Can you answer questions, Flobi?": Interactionally defining a robot’s competence as a fitness instructor. In: Proceedings of the 21th IEEE International Symposium in Robot and Human Interactive Communication (RO-MAN 2012). 2012.Users draw on four sources to judge a robot’s competence: (1) the robot’s voice, (2) physical appearance of and (3) the interaction experience with the robot but also (4) the relationship between the robot’s physical appearance and its conduct. Furthermore, most approaches in social robotics have an outcome-oriented focus and thus use questionnaires to measure a global evaluation of the robot after interaction took place. The present research takes a process-oriented approach to explore the factors relevant in the formation of users’ attitudes toward the robot. To do so, an ethnographic approach (Conversation Analysis) was employed to analyze the micro-coordination between user and robot. We report initial findings from a study in which a robot took the role of a fitness instructor. Our results emphasize that the participant judges step-by-step the robot’s capabilities and differentiates its competence on two levels regarding to the robot’s role: a robot as a (1) social/interactional co-participant and as a (2) fitness instructor

Serum dihydrotestosterone is associated with adverse myocardial remodeling in patients with aortic valve stenosis before and after aortic valve replacement

AIMS: Animal studies show a pivotal role of dihydrotestosterone (DHT) in pressure overload induced myocardial hypertrophy and dysfunction. The aim of our study was to evaluate the role of DHT levels and myocardial hypertrophy and myocardial protein expression in patients with severe aortic valve stenosis (AS). METHODS AND RESULTS: 43 patients (median age 68 (41-80) years) with severe AS and indication for surgical aortic valve replacement (SAVR) were prospectively enrolled. Cardiac magnetic resonance imaging including analysis of left ventricular muscle mass (LVM), fibrosis and function and laboratory tests including serum DHT levels were performed before and after SAVR. During SAVR left ventricular (LV) biopsies were performed for proteomic profiling. Serum DHT levels correlated positively with indexed LVM (LVMi, R=0.64, p<0.0001) and fibrosis (R=0.49, p=0.0065) and inversely with LV function (R=-0.42, p=0.005) in patients with severe AS. DHT levels were associated with higher abundance of the hypertrophy (moesin (R=0.52, p=0.0083)) and fibrosis (vimentin (R=0.41, p=0.039)) associated proteins from LV myocardial biopsies. Higher serum DHT levels preoperatively were associated with reduced LV function (ejection fraction: R=-0.34, p=0.035, circulatory efficiency: R=-0.46, p=0.012, global longitudinal strain: R=0.49, p=0.01) and increased fibrosis (R=0.55, p=0.0022) after SAVR. CONCLUSIONS: Serum DHT levels were associated with adverse myocardial remodeling and higher abundance in hypertrophy and fibrosis associated proteins in patients with severe AS. DHT may be a target to prevent or attenuate adverse myocardial remodeling in patients with pressure overload due to AS

Central Retinal Artery Occlusion: Current Practice, Awareness and Prehospital Delays in Switzerland

BACKGROUND AND PURPOSE: Central retinal artery occlusion (CRAO) often leads to permanent monocular blindness. Hence, early recognition and rapid re-perfusion is of paramount importance. This study aims to describe prehospital pathways in CRAO compared to stroke and study the knowledge about CRAO. METHODS: (1) Description of baseline characteristics, prehospital pathways/delays, and acute treatment (thrombolysis/thrombectomy vs. standard of care) of patients with CRAO and ischemic stroke registered in the Swiss Stroke Registry. (2) Online survey about CRAO knowledge amongst population, general practitioners (GPs) and ophthalmologists in Eastern Switzerland. RESULTS: Three hundred and ninety seven CRAO and 32,816 ischemic stroke cases were registered from 2014 until 2019 in 20 Stroke Centers/Units in Switzerland. In CRAO, 25.6% arrived at the hospital within 4 h of symptom onset and had a lower rate of emergency referrals. Hence, the symptom-to-door time was significantly longer in CRAO compared to stroke (852 min. vs. 300 min). The thrombolysis/thrombectomy rate was 13.2% in CRAO and 30.9% in stroke. 28.6% of the surveyed population recognized CRAO-symptoms, 55.4% of which would present directly to the emergency department in contrast to 90.0% with stroke symptoms. Almost 100% of the ophthalmologist and general practitioners recognized CRAO as a medical emergency and 1/3 of them considered IV thrombolysis a potentially beneficial therapy. CONCLUSIONS: CRAO awareness of the general population and physician awareness about the treatment options as well as the non-standardized prehospital organization, seems to be the main reason for the prehospital delays and impedes treating CRAO patients. Educational efforts should be undertaken to improve awareness about CRAO
