Use of Dysmorphology for Subgroup Classification on Autism Spectrum Disorder in Chinese Children

Data from 1,261 Chinese Autistic Spectrum Disorder (ASD) patients were evaluated and categorized into dysmorphic (10.79 %) and non-dysmorphic groups (89.21 %) upon physical examination by the presence of dysmorphic features. Abnormal MRI/CT result, IQ scores and epilepsy were significantly associated with the dysmorphic group of ASD children. However, gender, EEG abnormality and family history and recurrence of ASD were not found to be significantly different between group statuses. It is suggested that results collected from the Chinese population generally resembles that found in the Caucasians with ethnical differences still present. Current study supports the result shown in Miles' study (Miles et al. in Am J Med Genet 135A:171-180, 2005), in which heterogeneity subtypes of autism of different genetic origins which could be distinguished by presence of dysmorphic features on the patients.postprin

WiseNews database for upper primary students and teachers

Parallel Session 8 - 8.02 PaperElectronic databases are widely used by students and teachers at secondary and tertiary level to gather information for academic purposes. Few studies have investigated their use in primary education, especially in the Asian context. A pilot study conducted a year ago has shown that WiseNews, an electronic news database, was effective in facilitating the inquiry project-based learning of primary students at a school in Hong Kong. The current research extends the pilot study by examining the use of WiseNews by upper primary students and their teachers in five local primary schools. Automatic records of students’ and teachers’ database activities provided by WiseNews will be used to examine the usage habit of students and teachers. Students and teachers will be surveyed regarding their perceived usefulness of WiseNews database for learning and teaching purposes. Data collection and analysis adopted a mixed method design. The qualitative analysis will include an in-depth analysis of the types of articles retrieved by the students, in addition to the responses to the open-ended questions on the survey. This research will help teachers and school administrators to assess the effectiveness of WiseNews database in facilitating learning at upper primary levels.postprintThe International Conference on Primary Education, The Hong Kong Institute of Education, Hong Kong, China, 25-27 November 2009

Pilot study for subgroup classification for autism spectrum disorder based on dysmorphology and physical measurements in Chinese children

Poster Sessions: 157 - Comorbid Medical Conditions: abstract 157.058 58BACKGROUND: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder affecting individuals along a continuum of severity in communication, social interaction and behaviour. The impact of ASD significantly varies amongst individuals, and the cause of ASD can originate broadly between genetic and environmental factors. Objectives: Previous ASD researches indicate that early identification combined with a targeted treatment plan involving behavioural interventions and multidisciplinary therapies can provide substantial improvement for ASD patients. Currently there is no cure for ASD, and the clinical variability and uncertainty of the disorder still remains. Hence, the search to unravel heterogeneity within ASD by subgroup classification may provide clinicians with a better understanding of ASD and to work towards a more definitive course of action. METHODS: In this study, a norm of physical measurements including height, weight, head circumference, ear length, outer and inner canthi, interpupillary distance, philtrum, hand and foot length was collected from 658 Typical Developing (TD) Chinese children aged 1 to 7 years (mean age of 4.19 years). The norm collected was compared against 80 ASD Chinese children aged 1 to 12 years (mean age of 4.36 years). We then further attempted to find subgroups within ASD based on identifying physical abnormalities; individuals were classified as (non) dysmorphic with the Autism Dysmorphology Measure (ADM) from physical examinations of 12 body regions. RESULTS: Our results show that there were significant differences between ASD and TD children for measurements in: head circumference (p=0.009), outer (p=0.021) and inner (p=0.021) canthus, philtrum length (p=0.003), right (p=0.023) and left (p=0.20) foot length. Within the 80 ASD patients, 37(46%) were classified as dysmorphic (p=0.00). CONCLUSIONS: This study attempts to identify subgroups within ASD based on physical measurements and dysmorphology examinations. The information from this study seeks to benefit ASD community by identifying possible subtypes of ASD in Chinese population; in seek for a more definitive diagnosis, referral and treatment plan.published_or_final_versio

Developing multiple literacies for BSc Information Management students

This study examines the development of information, computer software, and Web 2.0 literacies among undergraduate students at the University of Hong Kong. A survey was administered to students undertaking the Bachelor of Science in Information Management three times: on entry, in the middle, and towards the completion of the program. It assessed their self-reported literacy levels and their perceptions of familiarity with and the importance of the three literacies. Preliminary findings indicated that students had improved in all three forms of literacy at the end of the two academic years. Moreover, positive associations were found between their familiarity with each literacy, and their perceptions of its importance. Mastering multiple literacies fosters life-long learning by enabling students to search for information effectively and use applications such as Web 2.0 tools and computer software to present their ideas in academic activities and ultimately in the workplace. Accordingly, the study has implications for educators and librarians working to develop multiple literacies among Hong Kong university students.postprin

What approaches to social prescribing work, for whom, and in what circumstances? A protocol for a realist review

The use of non-drug, non-health-service interventions has been proposed as a cost-effective alternative to help those with long-term conditions manage their illness and improve their health and well-being. Interventions typically involve accessing activities run by the third sector or community agencies and may also be described as non-medical referral, community referral or social prescribing. To be effective, patients need to be “transferred” from the primary care setting into the community and to maintain their participation in activities. However, it is not currently known how and why these approaches enable which people under what circumstances to reach community services that may benefit their health and well-being.The use of non-drug, non-health-service interventions has been proposed as a cost-effective alternative to help those with long-term conditions manage their illness and improve their health and well-being.

Policymakers\u27 experience of a capacity-building intervention designed to increase their use of research: A realist process evaluation

Background: An intervention’s success depends on how participants interact with it in local settings. Process evaluation examines these interactions, indicating why an intervention was or was not effective, and how it (and similar interventions) can be improved for better contextual fit. This is particularly important for innovative trials like Supporting Policy In health with Research: an Intervention Trial (SPIRIT), where causal mechanisms are poorly understood. SPIRIT was testing a multi-component intervention designed to increase the capacity of health policymakers to use research. Methods: Our mixed-methods process evaluation sought to explain variation in observed process effects across the six agencies that participated in SPIRIT. Data collection included observations of intervention workshops (n = 59), purposively sampled interviews (n = 76) and participant feedback forms (n = 553). Using a realist approach, data was coded for context-mechanism-process effect configurations (retroductive analysis) by two authors. Results: Intervention workshops were very well received. There was greater variation of views regarding other aspects of SPIRIT such as data collection, communication and the intervention’s overall value. We identified nine inter-related mechanisms that were crucial for engaging participants in these policy settings: (1) Accepting the premise (agreeing with the study’s assumptions); (2) Self-determination (participative choice); (3) The Value Proposition (seeing potential gain); (4) ‘Getting good stuff’ (identifying useful ideas, resources or connections); (5) Self-efficacy (believing ‘we can do this!’); (6) Respect (feeling that SPIRIT understands and values one’s work); (7) Confidence (believing in the study’s integrity and validity); (8) Persuasive leadership (authentic and compelling advocacy from leaders); and (9) Strategic insider facilitation (local translation and mediation). These findings were used to develop tentative explanatory propositions and to revise the programme theory. Conclusion: This paper describes how SPIRIT functioned in six policy agencies, including why strategies that worked well in one site were less effective in others. Findings indicate a complex interaction between participants’ perception of the intervention, shifting contextual factors, and the form that the intervention took in each site. Our propositions provide transferable lessons about contextualised areas of strength and weakness that may be useful in the development and implementation of similar studies
