Objective The purpose of this study was to evaluate the perceived effectiveness and learning potential of 3 Web-based educational methods in a postgraduate radiology setting. Methods Three chiropractic radiology faculty from diverse geographic locations led mini-courses using asynchronous discussion boards, synchronous Web conferencing, and asynchronous voice-over case presentations formatted for Web viewing. At the conclusion of each course, participants filled out a 14-question survey (using a 5-point Likert scale) designed to evaluate the effectiveness of each method in achieving specified course objectives and goals and their satisfaction when considering the learning potential of each method. The mean, standard deviation, and percentage agreements were tabulated. Results Twenty, 15, and 10 participants completed the discussion board, Web conferencing, and case presentation surveys, respectively. All educational methods demonstrated a high level of agreement regarding the course objective (total mean rating >4.1). The case presentations had the highest overall rating for achieving the course goals; however, all but one method still had total mean ratings >4.0 and overall agreement levels of 70%–100%. The strongest potential for interactive learning was found with Web conferencing and discussion boards, while case presentations rated very low in this regard. Conclusions The perceived effectiveness in achieving the course objective and goals was high for each method. Residency-based distance education may be a beneficial adjunct to current methods of training, allowing for international collaboration. When considering all aspects tested, there does not appear to be a clear advantage to any one method. Utilizing various methods may be most appropriate.

Objective: To test the acceptability, satisfaction, and effectiveness of a web-based intervention for teachers of elementary school–aged children with ADHD. Method: Elementary classroom teachers (N = 58), along with their students with ADHD, participated in a randomized controlled trial. The program consisted of six sessions that included evidence-based intervention strategies for reducing ADHD symptoms and impairment in the classroom setting. Teachers also had access to a moderated Discussion Board and an online ADHD coach. Questionnaire data were electronically collected from teachers and parents pre-intervention, post-intervention (6 weeks), and after an additional 6-week follow-up. Results: Intent-to-treat analyses found significant improvements based on teacher (but not parent) reports of core ADHD symptoms and impairment for the Teacher Help for ADHD treatment group. Teachers reported a high level of acceptability and satisfaction. Conclusion: Web-based ADHD interventions have the potential to reduce the barriers to treatment utilization and implementation that are common problems for school-based ADHD interventions.

Abstract Introduction Primary lymphoma of the colon is exceedingly rare and comprises 0.2–1% of all colon tumors. The most common subtype of lymphoma in the colon is non-Hodgkin lymphoma. Symptoms are often nonspecific, and treatment varies between chemotherapy alone and a combination of surgery and chemotherapy. Case presentation We describe a case of a Ashkenazi Jew patient who presented in the typical way that carcinoma of the colon might present but turned out to have a very rare type of tumor in both its histology and its location. Conclusion There was apparent discordance between the relative bulkiness and gross appearance of the tumor with the unrevealing result of the biopsies, demanding a high level of suspicion as to the actual presence and possible type of such a tumor in the future.

Edge computing is the best approach for meeting the exponential demand and the real-time requirements of many video analytics applications. Since most of the recent advances regarding the extraction of information from images and video rely on computation heavy deep learning algorithms, there is a growing need for solutions that allow the deployment and use of new models on scalable and flexible edge architectures. In this work, we present Deep-Framework, a novel open source framework for developing edge-oriented real-time video analytics applications based on deep learning. Deep-Framework has a scalable multi-stream architecture based on Docker and abstracts away from the user the complexity of cluster configuration, orchestration of services, and GPU resources allocation. It provides Python interfaces for integrating deep learning models developed with the most popular frameworks and also provides high-level APIs based on standard HTTP and WebRTC interfaces for consuming the extracted video data on clients running on browsers or any other web-based platform.

PurposeThis study examines whether online asynchronous discussion forums support student’s meaning-making about citizenship in a globalizing world. Citizenship is an increasingly contested identity for young people, yet they have few opportunities in traditional civic education to consider their own citizenship. Although online discussions are considered effective spaces for increasing dialogue and critical thinking between diverse students, there has been little research to understand how effective they are for helping students to construct new understandings of citizenship.Design/methodology/approachA content analysis approach was used to analyze and code 89 discussion board posts. The Interaction Analysis Model (IAM) coding scheme was used to describe and analyze the quality of knowledge construction that occurred across the posts focusing on different aspects of global citizenship.FindingsThe findings demonstrate that the discussion boards produced substantive talks about the meaning of citizenship that in some instances reached the level of new knowledge construction. The students considered different meanings for global citizenship and negotiated positions on key issues. However, the highest levels of knowledge construction were rarely reached.Practical implicationsA major implication is the need to organize and cue discussion boards to support knowledge construction in addition to fostering dialogue.Originality/valueThis study contributes to the role that technology can play in supporting students’ knowledge construction about global citizenship that go beyond the scripted meanings conveyed in civics classes.

Background: Sodium-Glucose co-Transporter 2 (SGLT2) inhibitors, a set of relatively new medicines treating type 2 diabetes showed a great number of merits in control of glycemia and cardiovascular risk factor management, but also attracted attention on bone fracture. One of those major effects on skeleton might be Parathyroid Hormone (PTH). Case Presentation: We present the case of a 68-year-old female patient with type 2 diabetes on insulin injection and oral acarbose therapy who was admitted with constant hyperglycemia to our hospital. In the beginning, she showed a high level of serum PTH. In the process of oral dapagliflozin treatment, PTH concentration firstly increased and then decreased to the normal range. Diagnostic tests are completed to exclude hyperparathyroidism. Conclusions: The use of SGLT2 inhibitors among diabetes and nondiabetic populations is increasing, a great deal of undiscovered influence, such as hormone and ion fluctuation needs further investigation.

Background:The purpose of this study was to examine the feasibility and effectiveness of a web-based intervention to promote physical activity and self-worth among working mothers.Methods:Participants (N = 69) were randomly assigned to receive a standard web-based intervention or an enhanced intervention that included group dynamics strategies to promote engagement. The 8-week intervention was guided by self-determination theory. Each week, participants were instructed to complete 3 tasks: listen to a podcast related to well-being, complete a workbook assignment, and communicate with other participants on a discussion board. Participants in the enhanced condition received an additional weekly task to enhance group cohesion. Data were collected at baseline, week 8, and week 16.Results:Physical activity (P < .001, η2 = 0.35) and self-worth (P < .001, η2 = 0.39) increased significantly in both groups following the intervention, and introjected (P < .001, η2 = 0.30) and external motivation (P = .04, η2 = 0.10) decreased. Website use declined across the 8-week intervention in both groups (P < .001, η2 = 0.48); however, discussion board use was higher in the enhanced condition (P = .04, η2 = 0.21).Conclusions:These findings suggest web-based interventions can improve physical activity and self-worth among working mothers. Group dynamics strategies only minimally enhanced user engagement, and future studies are needed to optimize web-based intervention designs.

Objective: To investigate the uptake and vaccination willingness of the COVID-19 vaccine among Chinese residents and analyze the difference and factors that impact vaccination. Methods: The snowball sampling method was used to distribute online questionnaires. Relevant sociodemographic data along with the circumstances of COVID-19 vaccination were collected from the respondents. The χ2 test, independent samples t test and binary logistic regression analysis were used to analyze the data. Results: Among 786 respondents, 84.22% had been vaccinated. Over 80% of the vaccinated population have completed all the injections because of supporting the national vaccination policies of China, while the unvaccinated population (23.91%) is mainly due to personal health status. Meanwhile, statistical analysis revealed that the main predictors of not being vaccinated were younger age (3 to 18 years old), personal health status, and lower vaccinated proportion of family members and close friends (p < 0.05). Conclusions: There was a high level of uptake of the COVID-19 vaccine in China, and people who have not been vaccinated generally had a low willingness to vaccinate in the future. Based on our results, it suggested the next work to expand the coverage of the COVID-19 vaccination should be concentrated on targeted publicity and education for people who have not been vaccinated.
