Psychotherapy via the Internet: What Programs Do Psychotherapists Use, How Well-Informed Do They Feel, and What Are Their Wishes for Continuous Education?

Abstract: The outbreak of the COVID-19 pandemic has caused changes in the provision of psychotherapy around the world. The common format of delivering in-person psychotherapy is replaced by psychotherapy via the Internet to a great extent. This study examined how well Austrian psychotherapists feel informed about the use of the Internet in psychotherapy, where additional information needs exist, and which software is used. A link to an online survey was sent to all psychotherapists providing a valid email address in the official list of licensed psychotherapists at the start of the COVID-19 lockdown in Austria. A total of 1547 people took part in the survey. The results show that psychotherapy via the Internet was primarily offered via Skype and Zoom during the COVID-19 pandemic and that the majority of the therapists felt well-informed about psychotherapy via the Internet; however, several therapists stated that they wish to have further information on data protection and security. Overall, the study shows that Austrian psychotherapists coped well with the rapid change from the provision of psychotherapy through personal contact to psychotherapy via the Internet. Security and data protection aspects of therapy via the Internet should be addressed in training and further education of psychotherapists. As this study was conducted online, it might have caused some respondent bias towards a higher participation of psychotherapists with higher preference for new technologies.

Patient development at a glance: an evaluation of a medical data visualization

Abstract: This paper describes the results of an evaluation study of a prototype for the visualization of time-oriented medical data. Subjects were nine physicians. The prototype combines well-known visual representation techniques and extensive interaction techniques. The aim of the study was to assess the system's usability and whether the prototype solved relevant problems of physicians in hospitals. It was found that one of the great advantages of the system was that it allowed physicians to see the development of the patients at one glance. It was also shown that users clearly preferred an easy to learn and understand design and familiar visualizations.

Differential Interaction of Platelet-Derived Extracellular Vesicles With Circulating Immune Cells: Roles of TAM Receptors, CD11b, and Phosphatidylserine

Abstract: Secretion and exchange of biomolecules by extracellular vesicles (EVs) are crucial in intercellular communication and enable cells to adapt to alterations in their microenvironment. EVs are involved in a variety of cellular processes under physiological conditions as well as in pathological settings. In particular, they exert profound effects on the innate immune system, and thereby are also capable of modulating adaptive immunity. The mechanisms underlying their interaction with their recipient cells, particularly their preferential association with monocytes and granulocytes in the circulation, however, remain to be further clarified. Surface molecules exposed on EVs are likely to mediate immune recognition and EV uptake by their recipient cells. Here, we investigated the involvement of Tyro3, Axl, and Mer (TAM) tyrosine kinase receptors and of integrin CD11b in the binding of platelet-derived EVs, constituting the large majority of circulating EVs, to immune cells in the circulation. Flow cytometry and Western Blotting demonstrated a differential expression of TAM receptors and CD11b on monocytes, granulocytes, and lymphocytes, as well as on monocyte subsets. Of the TAM receptors, only Axl and Mer were detected at low levels on monocytes and granulocytes, but not on lymphocytes. Likewise, CD11b was present on circulating monocytes and granulocytes, but remained undetectable on lymphocytes. Differentiation of monocytes into classical, intermediate, and non-classical monocyte subsets revealed distinct expression patterns of Mer and activated CD11b. Co-incubation of isolated monocytes and granulocytes with platelet-derived EVs showed that the binding of EVs to immune cells was dependent on Ca++. Our data do not support a particular role for TAM receptors or for activated CD11b in the association of platelet-derived EVs with monocytes and granulocytes in the circulation, as anti-TAM antibodies did not interfere with EV binding to isolated immune cells, as binding was not dependent on the presence of TIM4 acting synergistically with TAM receptors, and as neither low levels of Gas6, required as a linker between phosphatidylserine (PS) on the EV surface and TAM receptors on immune cells, nor masking of PS on the EV surface did interfere with EV binding.
