Complex Equiangular Cyclic Frames and Erasures

We derive various interesting properties of complex equiangular cyclic frames for many pairs (n, k) using Gauss sums and number theory. We further use these results to study the random and burst errors of some special cases of complex equiangular cyclic (n, k) frames

Report on the EHCR (Deliverable 26.2)

This deliverable is the second for Workpackage 26. The first, submitted after Month 12, summarised the areas of research that the partners had identified as being relevant to the semantic indexing of the EHR. This second one reports progress on the key threads of work identified by the partners during the project to contribute towards semantically interoperable and processable EHRs. This report provides a set of short summaries on key topics that have emerged as important, and to which the partners are able to make strong contributions. Some of these are also being extended via two new EU Framework 6 proposals that include WP26 partners: this is also a measure of the success of this Network of Excellence

Report on the EHCR (Deliverable 26.1)

The challenge of richly interpreting electronic health information, in order to populate EHR instances with suitable terms, to provide decision support in the care of individuals, to identify suitable patients for teaching or clinical trials recruitment, and to mine populations of records for public health or to discover new medical knowledge, all require that the heterogeneous clinical entry instances within EHR repositories can be systematically analysed and interpreted. Achieving this requires the combination and co-operation of many different health informatics tools and technologies, underpinned by shared representations of clinical concepts and inferencing formalisms. Much of this work is at the level of R&D, and is well represented across the Semantic Mining consortium. The challenge of WP26 is to build up a vision of the ways in which these historically independent threads of health informatics research can collaborate, and uncover the research challenges that are needed in order to deliver good demonstrations of semantically indexed and richly analysable EHRs. The partners have begun WP26 by acquiring a better knowledge of each other’s areas of endeavour, and are beginning to steer their research interests towards future areas of collaboration

Electronic health record standards

Objectives: This paper seeks to provide an overview of the initiatives that are proceeding internationally to develop standards for the exchange of electronic health record (EHR) information between EHR systems.Methods: The paper reviews the clinical and ethico-legal requirements and research background on the representation and communication of EHR data, which primarily originates from Europe through a series of EU funded Health Telematics projects over the post thirteen years. The major concept that underpin the information models and knowledge models are summarised. These provide the requirements and the best evidential basis from which HER communications standards should be developed.Results. The main focus of EHR communications standardisation is presently occurring at a European level, through the Committee for European Normalisation (CEN). The major constructs of the CEN 13606 model ate outlined. Complementary activity is taking place in ISO and in HL7, and some of these efforts are also summarised.Conclusior: There is a strong prospect that a generic EHR interoperability standard can be agreed at a European (and hopefully international) level. Parts of the challenge of EHR i interoperability cannot yet he standardised, because good solutions to the preservation of clinical meaning across heterogeneous systems remain to be explored. Further research and empirical projects are therefore also needed

The role of Coenzyme Q10 in statin-associated myopathy

Statins, or 3-hydroxyl-3-methylglutaryl coenzyme HMG-CoA reductase inhibitors,\ud are cholesterol-lowering drugs which are frequently used in the primary and secondary\ud prevention of coronary artery disease. Current research and recommendations support\ud and encourage more extensive use of these drugs.\ud However, statin usage is limited by many factors, including a high incidence of\ud statin-associated myalgia and myopathy. This review focuses on the use of Coenzyme Q\ud in statin-associated myopathy

EHR requirements

Published requirements for the EHR are principally available via ISO 18308. They are statements defining the generic features necessary in any Electronic Health Record for it to be communicable and complete, retain integrity across systems, countries and time, and be a useful and effective ethico-legal record of care. Examples of requirements are provided in four themes: -EHR functional requirements; Ethical, legal, and security requirements; Clinical requirements; Technical requirements. The main logical building blocks of an EHR are described using the terminology of CEN TC251 ENV13606. Examples are given of the placement of attributes to satisfy contextual and other requirements at the level of specific building blocks. A worked example of the use of the building blocks is given for the request-report cycle for an imaging investigation

Equality of certain automorphism groups of finite pp-groups

Let $G$ be a finite $p$-group and let Aut$(G)$ denote the full automorphism group of $G$. In the recent past, there has been interest in finding necessary and sufficient conditions on $G$ such that certain subgroups of Aut$(G)$ are equal. We prove a technical lemma and, as a consequence, obtain some new results and short and alternate proofs of some known results of this type.Comment: 6 page
