      OBJECTIVE: The objective of this study was to propose a graph-based semantic search approach by addressing the inherent complexity and ambiguity of medical terminology in queries and clinical text for enhanced medical information retrieval.METHODS: The supportive use of a medical domain ontology exploits the light-weight semantics discovered from queries and documents for enhanced document ranking. First, the implicit information regarding concepts and the relations between them is discovered in the documents and queries and is used to evaluate the relevance of the query-document; then, the semantic linkages between concepts distributed in target documents and reference documents are built and used to score the document's popularity; finally, the above two evaluations are integrated to produce the final ranking list for document ranking.
    RESULTS: Empirical experiments are conducted on two different datasets. The results demonstrate that the proposed graph-based approach significantly outperforms the baselines. For example, the average performance improvement on two datasets of the best variant of GSRM compared to the best baseline achieve 7.2% and 7.9% in terms of P@20 and NDCG@20, respectively, which illustrates the effectiveness of the proposed approach.

      INTRODUCTION: Many patients now turn to the internet as a resource for healthcare information and advice. However, patients' use of the internet to manage their health has been positioned as a potential source of strain on the doctor-patient relationship in primary care. The current evidence about what happens when internet-derived health information is introduced during consultations has relied on qualitative data derived from interview or questionnaire studies. The 'Harnessing resources from the internet to maximise outcomes from GP consultations (HaRI)' study combines questionnaire, interview and video-recorded consultation data to address this issue more fully.METHODS AND ANALYSIS: Three data collection methods are employed: preconsultation patient questionnaires, video-recorded consultations between general practitioners (GP) and patients, and semistructured interviews with GPs and patients. We seek to recruit 10 GPs practising in Southeast England. We aim to collect up to 30 patient questionnaires and video-recorded consultations per GP, yielding up to 300. Up to 30 patients (approximately three per participating GP) will be selected for interviews sampled for a wide range of sociodemographic characteristics, and a variety of ways the use of, or information from, the internet was present or absent during their consultation. We will interview all 10 participating GPs about their views of online health information, reflecting on their own usage of online information during consultations and their patients' references to online health information. Descriptive, conversation and thematic analysis will be used respectively for the patient questionnaires, video-recorded consultations and interviews.
    ETHICS AND DISSEMINATION: Ethical approval has been granted by the London-Camden & Kings Cross Research Ethics Committee. Alongside journal publications, dissemination activities include the creation of a toolkit to be shared with patients and doctors, to guide discussions of material from the internet in consultations.

      OBJECTIVES: Good knowledge translation efforts can lead to significant changes in health status and service delivery. Although there is growing literature around ways to conduct knowledge translation within policy and health service delivery sectors, literature around how to conduct dissemination within indigenous community-based contexts remains scant.STUDY DESIGN: Using creative, strengths-based approaches to not only return results but also to function as tools to address gaps in health knowledge as identified by participants and community members within intergenerational contexts was a central component applied to dissemination and knowledge translation.
    METHODS: We developed a series of seven key considerations that we applied to the creation of dissemination products from qualitative interviews and focus group discussions from two Manitoba, Canada-specific public health research projects with indigenous communities.
    RESULTS: Products created (activity sheets, board game, and non-fiction storybooks) considered principles of timeliness, literacy level, feasibility of reproduction, and meeting the stated needs of study participants.
    CONCLUSIONS: By creating products that seek not only to return study information but also to answer questions and address specific challenges identified by participants, it is possible to continue to engage in research that is meaningful and ethical and strengthens relationships with all stakeholders.

      OBJECTIVE: The authors' objective was to identify the 100 most-cited research articles on craniopharyngiomas.METHODS: The Thomson Reuters Web of Science service was queried for the years 1900-2017 without language restrictions. Articles were sorted in descending order of the number of times they were cited by other studies, and all titles and abstracts were screened to identify the research areas of the top 100 articles. The number of citations per year was calculated.
    RESULTS: The authors identified the 100 most-cited articles on craniopharyngioma, which collectively had been cited 20,994 times at the time of this writing. The top cited article was cited 718 times with an average of 144 citations per year since publication. The oldest article had been published in 1969 and the most recent in 2013; the most prolific decade was the 2000s, with 38 articles on this list having been published during that period. 32 unique journals contributed to the 100 articles, with the Journal of Neurosurgery contributing most of the articles (n = 31). The most common country of article origin was the United States (n = 49), followed by United Kingdom (n=12), Germany (n=10) and Italy (n=6).
    CONCLUSIONS: This study identified the 100 most-cited research articles in craniopharyngioma. The study highlighted the multidisciplinary and multimodal nature of craniopharyngioma management. Recognition of important historical contributions to this field may guide future investigations.
