A smartphone-enabled wireless and batteryless implantable blood flow sensor for Remote monitoring of prosthetic heart valve function
'Public Library of Science (PLoS)', 2020Co-Authors: Vennemann Bernhard, Obrist Dominik, Rösgen ThomasAbstract:Aortic valve disease is one of the leading forms of complications in the cardiovascular system. The failing native aortic valve is routinely surgically replaced with a bioprosthesis. However, insufficient durability of bioprosthetic heart valves often requires reintervention. Valve degradation can be assessed by an analysis of the blood flow characteristics downstream of the valve. This is cost and labor intensive using clinical methodologies and is performed infrequently. The integration of consumer smartphones and implantable blood flow sensors into the data acquisition chain facilitates Remote Management of patients that is not limited by access to clinical facilities. This article describes the characteristics of an implantable magnetic blood flow sensor which was optimized for small size and low power consumption to allow for batteryless operation. The data is wirelessly transmitted to the patient's smartphone for in-depth processing. Tests using three different experimental setups confirmed that wireless and batteryless blood flow recording using a magnetic flow meter technique is feasible and that the sensor system is capable of monitoring the characteristic flow downstream of the valv

telemedicine and Remote Management of patients with heart failure
The Lancet, 2011Co-Authors: Stefan D Anker, Friedrich Koehler, William T. AbrahamAbstract:Summary Advances in telecommunication technologies have created new opportunities to provide telemedical care as an adjunct to medical Management of patients with heart failure. Meta-analyses suggest that telemedicine can reduce morbidity and mortality in such patients; however, two prospective clinical trials not included in the analyses do not support these findings. Therefore, the effectiveness of telemedicine in heart failure is not established. Telemedicine approaches range from computer-based support systems to programmes led by nurses and physicians. Standardisation and appropriate classification of telemedical systems are needed to enable accurate interpretation of clinical trials. Here we propose a classification of four generations of telemedicine in heart failure. Not all approaches are the same and not every patient with heart failure will need telemedicine. Crisis prevention and treatment, and stabilisation and self-empowerment of patients are focuses of telemedicine in heart failure. The profile of patients who can potentially benefit from telemedicine is unknown and should be investigated in adequately powered randomised clinical trials. We are optimistic that telemedicine is an efficient approach and will become an important feature of Management in heart failure.

electric vehicle lease Management system on basis of charging piles and lease Management method implemented by electric vehicle lease Management system
2015Co-Authors: Ji XiaofengAbstract:The invention discloses an electric vehicle lease Management system on the basis of charging piles. The electric vehicle lease Management system comprises a system Remote Management control center, electric vehicles, the charging piles and intelligent terminals. A vehicle battery data acquisition module, a wireless communication module and an intelligent control module are mounted on each electric vehicle; an intelligent control unit and a communication module are mounted on each charging pile, each intelligent terminal is wirelessly communicated with the system Remote Management control center, and the wireless communication module of each electric vehicle is wirelessly communicated with the system Remote Management control center. The electric vehicle lease Management system has the advantages that lease systems which are used by vehicle lease users and Management staffs can be conveniently and quickly implemented by the aid of modern information network technologies, the users can order lease application and check relevant lease information via the intelligent terminals or directly via computers at any time in any places, and the Management staffs can monitor various indexes such as electric vehicle location data and battery data in real time, and prompting effects can be timely realized.

have traditional heart failure Management programs reached their use by date time to apply more nuanced care
Current Heart Failure Reports, 2019Co-Authors: Simon StewartAbstract:To determine the current evidence supporting the otherwise proven heart failure Management programs (HFMPs) in the setting of an increasingly older and more complex patient population. Attempts to replace proven face-to-face, multidisciplinary Management of HF with Remote Management techniques (including telemedicine and implantable Remote monitoring devices) have yielded mixed results. This may well reflect the clinical cascade effect of greater surveillance paradoxically leading to worse health outcomes as well as a narrow focus on HF alone in patients with clinically significant multimorbidity. Concurrently, there is preliminary evidence that the increasing phenomenon of HF and multimorbidity in older patients is undermining the otherwise positive impact of “traditional” HFMPs. A more nuanced approach to determining who would benefit from what form of HF Management, including the integration of Remote surveillance techniques, is required.

how Management accountants exert influence on managers a micro level analysis of Management accountants influence tactics in budgetary control meetings
Qualitative Research in Accounting & Management, 2017Co-Authors: Simone Mack, Lukas GoretzkiAbstract:This paper aims to examine how Remote (i.e. global, regional or divisional) Management accountants communicate in interpersonal contacts with operational managers when trying to exert influence on them.,An ethnographic field study focusing on budgetary control meetings between regional Management accountants and operational managers is used as the basis for a micro-level analysis of situated face-to-face interactions and communicative influence tactics.,Remote Management accountants mainly use soft rather than hard influence tactics. They, furthermore, employ what is referred to as “panoramic knowledge” gained explicitly from their structurally as well as physically removed “meta-positioning” to suggest certain measures to operational managers that have proved successful in other units and – by doing so – try to exert influence on these managers. Moreover, they use information that they gain in their position in between senior and operational managers by acting as “double agents” – that is, informing operational managers about senior managers’ focus as well as making transparent to operational managers that they will inform senior Management about specific operational matters. By doing so, they try to prompt operational managers to address these issues. Additionally, strengthening their verbally articulated suggestions, as “minute takers” they are able to document their suggestions by moving from spoken to a more binding written text. Through these purposeful and rather unobtrusive tactics, Remote Management accountants try to take influence on operational managers without generating their resistance.,The paper shows how Remote Management accountants (as staff members) can skillfully turn their apparently powerless position within the organization into a source of strength to exert influence on operational managers.
