Midwifery students' perspectives of physical and virtual mobility activities including preferences for e-learning: A cross-sectional survey.

BACKGROUND: Contemporary higher education requires that all midwifery students have insight and understanding of global health practice and demonstrate intercultural sensitivity. However, the mobility models currently offered do not often fit the lives of large numbers of midwifery students. OBJECTIVES: To investigate midwifery students' international physical mobility activities and factors that affect mobility; to determine midwifery students' learning needs and preferences for related e-learning packages. DESIGN: Multi-centre, descriptive quantitative survey. SETTINGS: Four European Higher Education Institutions based in the United Kingdom, Estonia, Italy and the Netherlands offering an undergraduate midwifery programme. PARTICIPANTS: The sample included 205 midwifery students from Italy (n = 93), the Netherlands (n = 51); United Kingdom (n = 35) and Estonia (n = 26). METHODS: Data were collected in June-July 2020 through an online cross-sectional, bespoke questionnaire and analysed using summary statistical analysis. RESULTS: There is a high level of interest across a range of mobility opportunities, especially those of shorter duration. Barriers to mobility comprised finance, caring responsibilities, concerns about fitting mobility activities into the midwifery programme, negative impact on studies and language barriers. The most frequently identified facilitators of mobility included professional perspectives such as interest in other cultures and midwifery in other settings and an endorsement that mobility would add value to their development as a midwife. When engaging in virtual learning, the most preferred resources mentioned by the students were videos, video calls with peers, choice quiz and discussion forum. CONCLUSIONS: The barriers identified require new approaches to enable all midwifery students to benefit from transnational learning. The survey findings provide insights into midwifery students' perspectives from which a new mobility model can be developed.

Growth control, structure, chemical state, and photoresponse of CuO-CdS core-shell heterostructure nanowires.

The growth of single-crystal CuO nanowires by thermal annealing of copper thin films in air is studied. We show that the density, length, and diameter of the nanowires can be controlled by tuning the morphology and structure of the copper thin films deposited by DC magnetron sputtering. After identifying the optimal conditions for the growth of CuO nanowires, chemical bath deposition is employed to coat the CuO nanowires with CdS in order to form p-n nanojunction arrays. As revealed by high-resolution TEM analysis, the thickness of the polycrystalline CdS shell increases when decreasing the diameter of the CuO core for a given time of CdS deposition. Near-edge x-ray absorption fine-structure spectroscopy combined with transmission x-ray microscopy allows the chemical analysis of isolated nanowires. The absence of modification in the spectra at the Cu L and O K edges after the deposition of CdS on the CuO nanowires indicates that neither Cd nor S diffuse into the CuO phase. We further demonstrate that the core-shell nanowires exhibit the I-V characteristic of a resistor instead of a diode. The electrical behavior of the device was found to be photosensitive, since increasing the incident light intensity induces an increase in the collected electrical current.

The role of taxonomies in social media and the semantic web for health education. A study of SNOMED CT terms in YouTube health video tags.

BACKGROUND: An increasing amount of health education resources for patients and professionals are distributed via social media channels. For example, thousands of health education videos are disseminated via YouTube. Often, tags are assigned by the disseminator. However, the lack of use of standardized terminologies in those tags and the presence of misleading videos make it particularly hard to retrieve relevant videos. OBJECTIVES: i) Identify the use of standardized medical thesauri (SNOMED CT) in YouTube Health videos tags from preselected YouTube Channels and demonstrate an information technology (IT) architecture for treating the tags of these health (video) resources. ii) Investigate the relative percentage of the tags used that relate to SNOMED CT terms. As such resources may play a key role in educating professionals and patients, the use of standardized vocabularies may facilitate the sharing of such resources. iii) Demonstrate how such resources may be properly exploited within the new generation of semantically enriched content or learning management systems that allow for knowledge expansion through the use of linked medical data and numerous literature resources also described through the same vocabularies. METHODS: We implemented a video portal integrating videos from 500 US Hospital channels. The portal integrated 4,307 YouTube videos regarding surgery as described by 64,367 tags. BioPortal REST services were used within our portal to match SNOMED CT terms with YouTube tags by both exact match and non-exact match. The whole architecture was complemented with a mechanism to enrich the retrieved video resources with other educational material residing in other repositories by following contemporary semantic web advances, in the form of Linked Open Data (LOD) principles. RESULTS: The average percentage of YouTube tags that were expressed using SNOMED CT terms was about 22.5%, while one third of YouTube tags per video contained a SNOMED CT term in a loose search; this analogy became one tenth in the case of exact match. Retrieved videos were then linked further to other resources by using LOD compliant systems. Such results were exemplified in the case of systems and technologies used in the mEducator EC funded project. CONCLUSION: YouTube Health videos can be searched for and retrieved using SNOMED CT terms with a high possibility of identifying health videos that users want based on their search criteria. Despite the fact that tagging of this information with SNOMED CT terms may vary, its availability and linked data capacity opens the door to new studies for personalized retrieval of content and linking with other knowledge through linked medical data and semantic advances in (learning) content management systems.

Pericardial synovial sarcoma of the heart; is it always worth operating?

Synovial sarcoma is a rare malignant soft-tissue tumor that most commonly occurs in the extremities of young adults. Primary pericardial synovial sarcoma is extremely rare. We report the case of a 37 year old male patient who presented with intermittent fever, nocturnal sweating and asthenia. Chest X-ray revealed an enlarged cardiac silhouette. Echocardiography identified pericardial effusion and a mass compressing the right ventricle. After percutaneous drainage of the effusion, the mass was not visible and deemed to have been septations of the effusion. Chest computed tomography (CT) did not show the mass visible on the X-ray. At one month follow-up, the pericardial mass was again visible on echocardiography and confirmed by magnetic resonance imaging (MRI). CT-guided biopsy showed malignant mesenchymal cells. Complete resection was attempted, but not possible due to diffuse infiltration of the epicardium. Histological examination of the resected tissue revealed an undifferentiated primary pericardial synovial sarcoma. The patient refused adjuvant treatment and died 15 days later. Surgical resection is considered the cornerstone of treatment of this rare type of malignant tumor of the young; our patient presented with a diffusely infiltrating tumor which could not be resected and required reoperation for tamponade and left pericardectomy. We question whether the choice to attempt resection was beneficial.

Revisiting Information Technology tools serving authorship and editorship: a case-guided tutorial to statistical analysis and plagiarism detection.

With the number of scientific papers published in journals, conference proceedings, and international literature ever increasing, authors and reviewers are not only facilitated with an abundance of information, but unfortunately continuously confronted with risks associated with the erroneous copy of another's material. In parallel, Information Communication Technology (ICT) tools provide to researchers novel and continuously more effective ways to analyze and present their work. Software tools regarding statistical analysis offer scientists the chance to validate their work and enhance the quality of published papers. Moreover, from the reviewers and the editor's perspective, it is now possible to ensure the (text-content) originality of a scientific article with automated software tools for plagiarism detection. In this paper, we provide a step-bystep demonstration of two categories of tools, namely, statistical analysis and plagiarism detection. The aim is not to come up with a specific tool recommendation, but rather to provide useful guidelines on the proper use and efficiency of either category of tools. In the context of this special issue, this paper offers a useful tutorial to specific problems concerned with scientific writing and review discourse. A specific neuroscience experimental case example is utilized to illustrate the young researcher's statistical analysis burden, while a test scenario is purpose-built using open access journal articles to exemplify the use and comparative outputs of seven plagiarism detection software pieces.

An e-learning platform for aerospace medicine.

The appeal of online education and distance learning as an educational alternative is ever increasing. To support and accommodate the over-specialized knowledge available by different experts, information technology can be employed to develop virtual distributed pools of autonomous specialized educational modules and provide the mechanisms for retrieving and sharing them. New educational standards such as SCORM and Healthcare LOM enhance this process of sharing by offering qualities like interoperability, accessibility, and reusability, so that learning material remains credible, up-to-date and tracks changes and developments of medical techniques and standards through time. Given that only a few e-learning courses exist in aerospace medicine the material of which may be exchanged among teachers, the aim of this paper is to illustrate the procedure of creating a SCORM compliant course that incorporates notions of recent advances in social web technologies. The course is in accordance with main educational and technological details and is specific to pulmonary disorders in aerospace medicine. As new educational trends place much emphasis in continuing medical education, the expansion of a general practitioner's knowledge in topics such as aviation and aerospace pulmonary disorders for crew and passengers becomes a societal requirement.
