Correlation of Web usage and exam performance in a human anatomy and development course

Course materials for a Human Anatomy and Development Course were placed on the World Wide Web (WWW). The materials included a lab manual, lecture notes and slides, faculty-generated atlases, Web links, and examinations. The lab manual, lecture notes, and atlases were also provided as black-and-white hardcopy. The Office of Education assigned students a code name that allowed them to use the Web site and take exams anonymously. Student Web use was tracked and correlated with their performance on the final examination. Overall use patterns revealed that most students used the Web site to prepare for examinations, but not for daily studying. Old examinations were the most accessed documents; lecture notes were the least accessed. The access patterns of the students with top 20, middle 20 (closest to the mean), and bottom 20 scores on the final examination were compared. In general, there was little difference between the middle and top groups. Students in the bottom group used computer resources significantly less than the other groups. In a second analysis, the 10 students who used the Web site most frequently scored below the mean. The study suggests that interactive exercises will be heavily used, but that the preparation of all course materials for the WWW may not be an efficient use of institutional resources.

OPEN TREATMENT OF SYNDACTYLY OF THE FOOT

The aim of reconstruction of the webs for syndactyly of the foot is cosmetic improvement, so skin grafting should be avoided. We present our long-term results of 19 feet with simple cutaneous syndactyly in 15 patients who were treated by an open technique. The bottom of the web was covered with a dorsal rectangular flap and the remaining skin defect was left open to epithelialise spontaneously. This took about 4 weeks. After a mean follow-up of 5.7 years (range 3-9), no hypertrophic scar or pigmentation of the skin had developed. Creeping of the web was seen only during the first postoperative year. The final depth of the web satisfied the families of all patients. As the aim of web reconstruction for syndactyly of the foot is purely cosmetic, we conclude that this simple method is reasonable treatment.     

Research progress in rehabilitation treatment of stroke patients A bibliometric analysis

BACKGROUND: Stroke presents as a transient or chronic brain dysfunction and is associated with high morbidity and high mortality. The doctors and scientists would like to argue how to enhance the validity of the rehabilitation treatment and how to further improve the level of treatment on stroke. OBJECTIVE: The aim of this study was to quantitatively analyze the current worldwide progress in research on stroke rehabilitation treatment based on Web of Science database and ClinicalTrial.gov in the past 10 years. METHODS: We conducted a quantitative analysis of clinical trial articles regarding stroke rehabilitation published in English from 2003 to 2013 and indexed in the National Institutes of Health Clinical Trials registry and Web of Science databases. Data were downloaded on March 15, 2013. RESULTS: (1) From 2003 to 2013, 2 654 clinical trials investigating stroke were indexed in ClinicalTrials.gov. There were only 58 clinical trials registered in 2003, and there was a marked increase from 2005. A total of 605 clinical trials on the rehabilitation of stroke were conducted in the past 10 years. (2) The analysis showed that most of the trials in the field were registered by North American institutions. With respect to the Asian countries, China and Taiwan area of China also published a reasonable proportion of the trials, but comparatively speaking, the number of trials is really rare. Most of the interventions were drugs, followed by the devices, and behavioral interventions were ranked third. (3) In the past 10 years, there were 4 052 studies on stroke indexed by Web of Science database. CONCLUSION: From perspective of research progress, we found that the number of clinical trials and papers on stroke rehabilitation has increased significantly in the past 10 years, between them a remarkable positive correlation exists.     

The top cited articles on glioma stem cells in Web of Science

BACKGROUND: Glioma is the most common intracranial tumor and has a poor patient prognosis. The presence of brain tumor stem cells was gradually being understood and recognized, which might be beneficial for the treatment of glioma. OBJECTIVE: To use bibliometric indexes to track study focuses on glioma stem cell, and to investigate the relationships among geographic origin, impact factors, and highly cited articles indexed in Web of Science. METHODS: A list of citation classics for glioma stem cells was generated by searching the database of Web of Science-Expanded using the terms "glioma stem cell" or "glioma, stem cell’" or "brain tumor stem cell". The top 63 cited research articles which were cited more than 100 times were retrieved by reading the abstract or full text if needed. Each eligible article was reviewed for basic information on subject categories, country of origin, journals, authors, and source of journals. Inclusive criteria: (1) articles in the field of glioma stem cells which was cited more than 100 times; (2) fundamental research on humans or animals, clinical trials and case reports; (3) research article; (4) year of publication: 1899-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles needing to be manually searched or accessed only by telephone; (2) unpublished articles; and (3) reviews, conference proceedings, as well as corrected papers. RESULTS: Of 2 040 articles published, the 63 top-cited articles were published between 1992 and 2010. The number of citations ranged from 100 to 1 754, with a mean of 280 citations per article. These citation classics came from nineteen countries, of which 46 articles came from the United States. Duke University and University of California, San Francisco led the list of classics with seven papers each. The 63 top-cited articles were published in 28 journals, predominantly Cancer Research and Cancer Cell, followed by Cell Stem Cell and Nature. CONCLUSION: Our bibliometric analysis provides a historical perspective on the progress of glioma stem cell research. Articles originating from outstanding institutions of the United States and published in high-impact journals are most likely to be cited.     

An exploration of four web-based open and flexible learning modules in post-registration nurse education

This paper presents an exploratory evaluation of four newly developed web-based modules for post-registration nurses. The topics for the modules were: dermatology; diabetes; mentorship; and prescribing. STUDY OBJECTIVE: To explore the students' perceptions of the web-based modules before and after completing the modules. DESIGN: A pre-post test design using questionnaires and group interviews. PARTICIPANTS: 39 students enrolled on the modules, pre-module data were collected on 74% (n = 29) and post-module data on 71% (n = 28). None of students had previous web-based education experience. 79% (n = 31) completed and 66% (n = 26) passed the modules. Students level of IT skills prior to commencing the modules were important in explaining module completion and outcome. The modules were rated highly in terms of achieving learning outcomes with moderate ratings for level of support and utility of learning materials. The content analysis of the interviews highlighted the importance of preparing students ensuring they have the IT and independent learning skills necessary to participate in web-based learning programmes, together with a number of issues relating to the accessibility of the learning materials. The perceived benefits of this mode of learning were that they offered flexible and resource rich learning. The downside was that the learning can be isolating. CONCLUSIONS: This form of learning may not be suited to all groups of nurses or all educational topics. Further research is required to establish the educational benefits of different approaches to e-learning.

Validation of an informant-reported web-based data collection to assess dementia symptoms

Background

The Web offers unprecedented access to the experience of people with dementia and their care partners, but data gathered online need to be validated to be useful.

Objective

To test the construct validity of an informant Web-based data collection to assess dementia symptoms in relation to the 15-point Dependence Scale (DS).

Methods

In an online survey posted on the DementiaGuide website, care partners of people with dementia built individualized profiles from the 60-item SymptomGuide and completed a questionnaire, which included the DS and a staging tool.

Results

In the 250 profilees (155, 62% women, mean age 77 years), increasing dependence was associated with a greater chance of institutionalization. For example, no one at the lowest levels of dependence (DS score < 5, n = 33) was in long-term care, compared with half (13/25) of the profilees at the highest levels of dependence (DS score > 12) being in institutions (χ² ₄ = 27.9, P < .001). The Web-based DS was correlated with the number of symptoms: higher DS scores were associated with a higher stage of dementia (F > 50, P < .001).

Conclusion

In an online survey, the Web-based DS showed good construct validity, potentially demonstrating how the Web can be used to learn more about dementia progression and how it relates to symptoms experienced by patients across the course of dementing illnesses. Even so, caution is needed to assure the validity of data collected online.
