Ventricular arrhythmia burden in patients with implantable cardioverter defibrillator and remote patient monitoring during different time intervals of the COVID-19 pandemic

Purpose The current study investigated whether the changes in patient care in times of the COVID-19 pandemic, especially the reduction of in-person visits, would result in a deterioration of the arrhythmic and clinical condition of patients with an implantable cardioverter defibrillator (ICD) and remote patient monitoring. Methods Data were obtained from a local ICD registry. 140 patients who received ICD implantation at our department and had remote patient monitoring were included. The number of patients with ventricular arrhythmias, appropriate ICD therapy, the number of visits to our outpatient clinic and hospitalization due to acute coronary syndrome, stroke or heart failure were compared during three time intervals of the COVID-19 pandemic (first (LD1) and second (LD2) national lockdown in Germany and the time after the first lockdown (postLD1)) and a time interval 1 year before the pandemic began (preCOV). Each time interval was 49 days long. Results Patients had significantly fewer visits to our outpatient clinic during LD1 (n = 13), postLD1 (n = 22) and LD2 (n = 23) compared to the time interval before the pandemic (n = 43, each p ≤ 0.05). The number of patients with sustained ventricular arrhythmias, appropriate ICD therapy and clinical events showed no significant difference during the time intervals of the COVID-19 pandemic and the time interval 1 year prior. Conclusions The lockdown measures necessary to reduce the risk of infection during the COVID-19 pandemic, led to a reduction of in-person patient visits, but did not result in a deterioration of the arrhythmic and clinical condition of ICD patients with remote patient monitoring

08421 Working Group: Lineage/Provenance

The following summary tries to capture a collection of state-of-the-art techniques and challenges for future work on lineage management in uncertain and probabilistic databases that we discussed in our working group. It was one half of a larger committee that we had initially formed, which then got split into two groups---one focusing on lineage as a means of explanation of data, and one focusing more on lineage usage in probabilistic databases (see also the "Explanation" working group report for more details on the first subgroup)

08421 Working Group: Uncertainty and Trust

This report summarizes the findings of a working group on "Uncertainty and Trust" which met during Dagstuhl Seminar 08421 "Uncertainty Management in Information Systems". All participants of the working group are co-authors of this report. The aim of the working group was to analyse the relationship between trust and uncertainty in distributed reputation systems. We started by identifying sources and types of uncertainty in this context and investigated their relation to trust. After that we compiled a list of desirable properties of trust representations and finally determined open research challenges in the area

How Semantic Technologies can Enhance Data Access at Siemens Energy

We present a description and analysis of the data access challenge in the Siemens Energy. We advocate for Ontology Based Data Access (OBDA) as a suitable Semantic Web driven technology to address the challenge. We derive requirements for applying OBDA in Siemens, review existing OBDA systems and discuss their limitations with respect to the Siemens requirements. We then introduce the Optique platform as a suitable OBDA solution for Siemens. Finally, we describe our preliminary installation and evaluation of the platform in Siemens.© Springer International Publishing Switzerland.
