Summary Objectives: To provide an overview of outstanding current research conducted in Education and Consumer Informatics. Method: Synopsis of the articles on education and consumer health informatics published in 2012 and selected for the IMIA Yearbook of Medical Informatics 2013. Results: Architecture of monitoring or telehealth information systems for patients with chronic disease must include wireless devices to aid in the collection of personal data. Data acquisition technologies have an impact on patients' willingness to participate in telehealth programmes. Patients are more likely to prefer mobile applications over web-based applications. Social media is widely used by clinicians. Especially younger clinicians use it for personal purposes and for reference materials retrieval. Questions remain on optimal training requirements and on the effects on clinician behavior and on patient outcomes. A high level of e-Health literacy by patients will promote increased adoption and utilization of personal health records. Conclusion: The selected articles highlight the need for training of clinicians to become aware of existing telehealth systems, in order to correctly inform and guide patients to take part in telehealth systems and adopt personal healthcare records (PHR).

In this paper, we investigate ontology-supported interfaces for health informatics search tasks involving large document sets. We begin by providing background on health informatics, machine learning, and ontologies. We review leading research on health informatics search tasks to help formulate high-level design criteria. We use these criteria to examine traditional design strategies for search interfaces. To demonstrate the utility of the criteria, we apply them to the design of ONTology-supported Search Interface (ONTSI), a demonstrative, prototype system. ONTSI allows users to plug-and-play document sets and expert-defined domain ontologies through a generalized search interface. ONTSI’s goal is to help align users’ common vocabulary with the domain-specific vocabulary of the plug-and-play document set. We describe the functioning and utility of ONTSI in health informatics search tasks through a workflow and a scenario. We conclude with a summary of ongoing evaluations, limitations, and future research.

AbstractThe paper attempts a balanced look at the directions of health informatics required in the future. In a high level review of impediments to health and health care a number of issues are identified that may be amenable to improvement by contributions from health informatics. Attention is drawn to the improvement ofthe collection and dissemination of knowledge in addition to the analysis of morbid conditions as a focus for health informatics. On this basis a review of the current state of health information systems is undertaken. The importance of adaptable user interfaces for end users and systems personnel, privacy and confidentiality protection, and linkage among clinical support systems and knowledge repositories is stressed. These improvements hinge on advancements in medical concept representation. Canadian contributions to these developments, particularly the instigation of Evidence Based Medicine (EBM) are briefly reviewed.

Summary Background: Education has long been, and continues to be, one of the major thematic areas of the activities of IMIA, the International Medical Informatics Association. Objective: To report on IMIA’s past activities and to discuss possible future perspectives on IMIA’s role on biomedical and health informatics education. Methods: Summarizing past activities by searching in reports and publications. Making suggestions for wider discussion on possible future activities. Results: Since its inception, IMIA has been active in the field of education, mainly through its working group on education. Among other activities, nine working conferences have been held, many of which have resulted in publications as outcomes, which have helped to exchange knowledge on the development of high-quality health and biomedical informatics education. Recommendations on education in health and medical informatics were endorsed by IMIA in 1999, and a revised version is currently in preparation. Conclusions: IMIA should continue to stimulate the exchange of knowledge on a range of aspects of health and biomedical informatics education in the countries and regions of the world, with IMIA’s academic institutional members playing an increasing role. Establishing procedures for the international accreditation of high-level programs in health and biomedical informatics through IMIA is one of several areas that need to be discussed as IMIA plans and develops its future activities.

A multisubunit RNA polymerase enzyme is ultimately responsible for transcription initiation and elongation of RNA, but recognition of the proper start site by the enzyme is regulated by general, temporal and gene-specific trans-factors interacting at promoter and enhancer DNA sequences. To understand the molecular mechanisms which precisely regulate the transcription initiation event, it is crucial to elucidate the structure of the transcription factor/DNA complexes involved. Electron spectroscopic imaging (ESI) provides the opportunity to visualize individual DNA molecules. Enhancement of DNA contrast with ESI is accomplished by imaging with electrons that have interacted with inner shell electrons of phosphorus in the DNA backbone. Phosphorus detection at this intermediately high level of resolution (≈lnm) permits selective imaging of the DNA, to determine whether the protein factors compact, bend or wrap the DNA. Simultaneously, mass analysis and phosphorus content can be measured quantitatively, using adjacent DNA or tobacco mosaic virus (TMV) as mass and phosphorus standards. These two parameters provide stoichiometric information relating the ratios of protein:DNA content.

The forte of the Scanning transmission Electron Microscope (STEM) is high resolution imaging with high contrast on thin specimens, as demonstrated by visualization of single heavy atoms. of equal importance for biology is the efficient utilization of all available signals, permitting low dose imaging of unstained single molecules such as DNA.Our work at Brookhaven has concentrated on: 1) design and construction of instruments optimized for a narrow range of biological applications and 2) use of such instruments in a very active user/collaborator program. Therefore our program is highly interactive with a strong emphasis on producing results which are interpretable with a high level of confidence.The major challenge we face at the moment is specimen preparation. The resolution of the STEM is better than 2.5 A, but measurements of resolution vs. dose level off at a resolution of 20 A at a dose of 10 el/A2 on a well-behaved biological specimen such as TMV (tobacco mosaic virus). To track down this problem we are examining all aspects of specimen preparation: purification of biological material, deposition on the thin film substrate, washing, fast freezing and freeze drying. As we attempt to improve our equipment/technique, we use image analysis of TMV internal controls included in all STEM samples as a monitor sensitive enough to detect even a few percent improvement. For delicate specimens, carbon films can be very harsh-leading to disruption of the sample. Therefore we are developing conducting polymer films as alternative substrates, as described elsewhere in these Proceedings. For specimen preparation studies, we have identified (from our user/collaborator program ) a variety of “canary” specimens, each uniquely sensitive to one particular aspect of sample preparation, so we can attempt to separate the variables involved.

Purpose A questionnaire survey was conducted to collect information from clinical audiologists about rehabilitation options for adult patients who report significant auditory difficulties despite having normal or near-normal hearing sensitivity. This work aimed to provide more information about what audiologists are currently doing in the clinic to manage auditory difficulties in this patient population and their views on the efficacy of recommended rehabilitation methods. Method A questionnaire survey containing multiple-choice and open-ended questions was developed and disseminated online. Invitations to participate were delivered via e-mail listservs and through business cards provided at annual audiology conferences. All responses were anonymous at the time of data collection. Results Responses were collected from 209 participants. The majority of participants reported seeing at least one normal-hearing patient per month who reported significant communication difficulties. However, few respondents indicated that their location had specific protocols for the treatment of these patients. Counseling was reported as the most frequent rehabilitation method, but results revealed that audiologists across various work settings are also successfully starting to fit patients with mild-gain hearing aids. Responses indicated that patient compliance with computer-based auditory training methods was regarded as low, with patients generally preferring device-based rehabilitation options. Conclusions Results from this questionnaire survey strongly suggest that audiologists frequently see normal-hearing patients who report auditory difficulties, but that few clinicians are equipped with established protocols for diagnosis and management. While many feel that mild-gain hearing aids provide considerable benefit for these patients, very little research has been conducted to date to support the use of hearing aids or other rehabilitation options for this unique patient population. This study reveals the critical need for additional research to establish evidence-based practice guidelines that will empower clinicians to provide a high level of clinical care and effective rehabilitation strategies to these patients.
