A checklist for reporting, reading and evaluating Artificial Intelligence Technology Enhanced Learning (AITEL) research in medical education.

Advances in Artificial Intelligence (AI) have led to AI systems' being used increasingly in medical education research. Current methods of reporting on the research, however, tend to follow patterns of describing an intervention and reporting on results, with little description of the AI in the system, or the many concerns about the use of AI. In essence, the readers do not actually know anything about the system itself. This paper proposes a checklist for reporting on AI systems, and covers the initial protocols and scoping, modelling and code, algorithm design, training data, testing and validation, usage, comparisons, real-world requirements, results and limitations, and ethical considerations. The aim is to have a systematic reporting process so that readers can have a comprehensive understanding of the AI system that was used in the research.

Canadian Palliative Community Milrinone Infusions: A Case Series.

Abstract Symptom managementfor end-of-life heartfailure (HF) patients is a significant concern. Currently, Canadian practice does not support community milrinone therapy in end-of-life HF patients. Two patients had severe HF that was unresponsive to optimal medications. Further optimization and furosemide infusions were ineffective for symptom management. Both patients' symptoms were better controlled with optimal medication, furosemide, and milrinone infusions. A tailored discharge plan was developed to assist with community milrinone infusions. We discuss the challenges and successes of transitioning two patients to the community. By providing symptom management and meaningful patient and family experience, both patients were able to die in a setting of their choosing. Milrinone infusions as a bridge to end of life may improve symptoms and quality of life. Select patients may benefit from milrinone infusions with resources put in place; these end-of-life HF patients can be supported in the community.

Crowdsource authoring as a tool for enhancing the quality of competency assessments in healthcare professions.

The current Objective Structured Clinical Examination (OSCE) is complex, costly, and difficult to provide high-quality assessments. This pilot study employed a focus group and debugging stage to test the Crowdsource Authoring Assessment Tool (CAAT) for the creation and sharing of assessment tools used in editing and customizing, to match specific users' needs, and to provide higher-quality checklists. Competency assessment international experts (n = 50) were asked to 1) participate in and experience the CAAT system when editing their own checklist, 2) edit a urinary catheterization checklist using CAAT, and 3) complete a Technology Acceptance Model (TAM) questionnaire consisting of 14 items to evaluate its four domains. The study occurred between October 2018 and May 2019. The median time for developing a new checklist using the CAAT was 65.76 minutes whereas the traditional method required 167.90 minutes. The CAAT system enabled quicker checklist creation and editing regardless of the experience and native language of participants. Participants also expressed the CAAT enhanced checklist development with 96% of them willing to recommend this tool to others. The use of a crowdsource authoring tool as revealed by this study has efficiently reduced the time to almost a third it would take when using the traditional method. In addition, it allows collaborations to partake on a simple platform which also promotes contributions in checklist creation, editing, and rating.

Asymptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in adults is uncommon using rigorous symptom characterization and follow-up in an acute-care adult hospital outbreak.

Asymptomatic coronavirus disease 2019 (COVID-19) has been reported as a significant driver of COVID-19 outbreaks. Our hospital ward outbreak analysis suggests that comprehensive symptoms and signs assessment, in combination with adequate follow-up, allows a more precise determination of COVID-19 symptoms. Asymptomatic infection was quite uncommon among adults in this setting.

Patient and ward related risk factors in a multi-ward nosocomial outbreak of COVID-19: Outbreak investigation and matched case-control study.

BACKGROUND: Risk factors for nosocomial COVID-19 outbreaks continue to evolve. The aim of this study was to investigate a multi-ward nosocomial outbreak of COVID-19 between 1st September and 15th November 2020, occurring in a setting without vaccination for any healthcare workers or patients. METHODS: Outbreak report and retrospective, matched case-control study using incidence density sampling in three cardiac wards in an 1100-bed tertiary teaching hospital in Calgary, Alberta, Canada. Patients were confirmed/probable COVID-19 cases and contemporaneous control patients without COVID-19. COVID-19 outbreak definitions were based on Public Health guidelines. Clinical and environmental specimens were tested by RT-PCR and as applicable quantitative viral cultures and whole genome sequencing were conducted. Controls were inpatients on the cardiac wards during the study period confirmed to be without COVID-19, matched to outbreak cases by time of symptom onset dates, age within ± 15 years and were admitted in hospital for at least 2 days. Demographics, Braden Score, baseline medications, laboratory measures, co-morbidities, and hospitalization characteristics were collected on cases and controls. Univariate and multivariate conditional logistical regression was used to identify independent risk factors for nosocomial COVID-19. RESULTS: The outbreak involved 42 healthcare workers and 39 patients. The strongest independent risk factor for nosocomial COVID-19 (IRR 3.21, 95% CI 1.47-7.02) was exposure in a multi-bedded room. Of 45 strains successfully sequenced, 44 (97.8%) were B.1.128 and differed from the most common circulating community lineages. SARS-CoV-2 positive cultures were detected in 56.7% (34/60) of clinical and environmental specimens. The multidisciplinary outbreak team observed eleven contributing events to transmission during the outbreak. CONCLUSIONS: Transmission routes of SARS-CoV-2 in hospital outbreaks are complex; however multi-bedded rooms play a significant role in the transmission of SARS-CoV-2.

Virtual reality enhancing medical education and practice: Brief communication.

The COVID-19 pandemic has become a major cause of rapid globalization and digitization of educational institutions, including medical education. The adaptation to digital technologies is the purpose of best education and training practices in the development of the academic medical curriculum. Virtual reality (VR) is embraced by the 3D environment and network resources which allow the expansion of VR from the entertainment industry to the education industry. This brief communication explains our understanding and the challenges in adopting VR technologies for medical training at an academic medical center. Advancement in VR technology assists medical institutes to strategize for the further development of medical training and education. There is a timely need for persistence to make the VR content accessible widely and open source. There is an urgent need for collaboration of medical institutes and technology industries on the development of education-related VR content and simulations.

Frequently Used Conceptual Frameworks and Design Principles for Extended Reality in Health Professions Education.

Health professions education (HPE) has witnessed a dramatic increase in the use of extended reality (XR), but there is limited evidence that conceptual frameworks are being effectively employed in the design and implementation of XR. This paper introduces commonly utilized conceptual frameworks that can support the integration of XR into the learning process and design principles that can be helpful for the development and evaluation of XR educational applications. Each framework and design principle is summarized briefly, followed by a description of its applicability to XR for HPE and an example of such application.

Effective online large-group teaching in health professions education.

Online large-group teaching (OLGT), employed to reach a large group of learners in separate physical locations, allows asynchronous learning and facilitates social distancing. While online large-groups can be a powerful and resource-lean means of health professions education, it has challenges and potential pitfalls that may affect the learning process and outcomes. Through a sociomateriality framework, this article describes strategies for effective online large-group teaching in health professions education in three key strands. Firstly, to optimize learning, OLGT sessions should match learning needs with appropriate OLGT platforms, incorporate strategies to sustain learner attention, and accommodate learners of different abilities. Secondly, to develop a learning culture, OLGT must not only focus on cognitive aspects of learning but also build a community of practice, nurture digital professionalism and professional identity. Thirdly, we discuss the avoidance of pitfalls such as cognitive overload of both tutors and learners, technical issues and security risks, mitigating inequities in access to online learning, and the use of program evaluation to plan for sustained improvements. We conclude with a case vignette that discusses the challenges of OLGT and the application of the above strategies in a teaching scenario.

Impact of virtual reality anatomy training on ultrasound competency development: A randomized controlled trial.

PURPOSE: The use of Virtual Reality (VR) in health professions education has increased dramatically in recent years, yet there is limited evidence of its impact on educational outcomes. The purpose of the study was to assess the impact of VR anatomy instruction on the ultrasound competency of novice learners participating in a ultrasonography workshop. METHOD: We designed a VR-enhanced ultrasonography training program and utilized a plane transection tool to interact with a three-dimensional (3D) VR model of the human body which facilitated the 3D conceptualization of the spatial relationship of anatomical structures, leading to faster and better development of ultrasonographic competency. This was a randomized control study which enrolled third-year medical students (n = 101) without previous exposure to formal or informal ultrasonography training. The participants were randomly divided into an intervention and control group. We assessed participants' competency through ultrasound performance stations on live subjects, we also measured anatomical and ultrasound image identification ability using multiple choice tests. RESULT: Participants in the intervention group (median = 16; interquartile 13 to 19) had significantly higher scores in ultrasonography task performance tests than the control group (median = 10; interquartile 7 to 14; Mann-Whitney U = 595; P < 0.01). In sub-group analysis, the intervention group performed significantly better in the six out of ten ultrasound tasks. Participants in the intervention group also had greater improvement in ultrasonographic image identification MCQ tests than the control group (Mann-Whitney U = 914; P < 0.05). CONCLUSION: This study suggests that VR-enhanced anatomical training could be of significant benefit in ultrasonography training by promoting a better understanding of the spatial relationships of anatomical structures and the development of early psychomotor skills transferable to the handling of ultrasonographic probes.

Hipercalemia inducida por trimetoprim-sulfametoxazol / Hyperkalemia induced by trimethoprim-sulfamethoxazole

Resumen: La hipercalemia inducida por el trimetoprim-sulfametoxazol, descrita en 1983, es un efecto secundario relativamente común pero en ocasiones no diagnosticado que puede poner en peligro la vida de los pacientes. Existen condiciones que aumentan el riesgo de padecerla, entre las que se encuentran, por ejemplo, la diabetes mellitus y la administración de inhibidores del sistema renina-angiotensina. Se describe el caso de una paciente que, al tercer día de administración de trimetoprim-sulfametoxazol para el tratamiento de una infección de vías urinarias recurrente tuvo hipercalemia severa en el contexto del tratamiento conjunto con inhibidores del sistema renina-angiotensina, que remitió con medidas anticalémicas y con la suspensión del tratamiento antibiótico.

Abstract: Hyperkalemia induced by trimethoprim-sulfamethoxazole therapy, described in 1983, is a frequent, yet less thought-off complication that can be dangerous and can cause death. There are conditions that increase the risk of presenting it, including, for example, diabetes mellitus and the use of renin-angiotensin system inhibition. This paper describes the case of a female patient who, on the third day of administration of trimethoprim-sulfamethoxazole for the management of a recurrent urinary tract infection, presented severe hyperkalemia, in the context of concomitant use of renin-angiotensin system inhibition, that was cured with antikalemic measures and with the suspension of antibiotic treatment.

Gastric emphysema a spectrum of pneumatosis intestinalis: a case report and literature review.

The finding of gas within the gastric wall is not a disease by itself, rather than a sign of an underlying condition which could be systemic or gastric. We present the case of a woman identified with gastric emphysema secondary to the administration of high doses of steroids, with the purpose of differentiating emphysematous gastritis versus gastric emphysema due to the divergent prognostic implications. Gastric emphysema entails a more benign course, opposed to emphysematous gastritis which often presents as an acute abdomen and carries a worse prognosis. Owing to the lack of established diagnostic criteria, computed tomography is the assessment method of choice. Currently no guidelines are available for the management of this entity, since the evidence is limited to a few case series and a considerable number of single case reports.

J. K. Rowling y Severus Snape: dos caras de la misma moneda. Una comparación de las organizaciones de significado personal de la autora y un personaje de la octología de Harry Potter / J. K. Rowling and Severus Snape: two sides of the same coin. A comparison of personal meaning organizations of the author and a character in Harry Potter's octology

La presente investigación, tiene como objetivo la realización de un perfil psicológico de J.k Rowling y de Severus Snape, personaje de la heptalogía de libros de Harry Potter, de la autoría de Rowling. Este perfil se basa en la revisión del material cinematográfico, de la octología basada en los libros ya mencionados y en la película Magic Beyond Words, basada en la vida de J.K Rowling, además de la perspectiva de la psicología cognitiva-postracional. Dentro de los principales resultados encontrados, está el hecho que J.K. Rowling y Severus Snape tienen el mismo patrón de apego, pero no la misma organización de significado personal (OSP), debido a que Rowling es OSP obsesiva y Severus es OSP depresivo; sin embargo, por su configuración de apego evitante, sí son dos caras de la misma moneda.

This research aims to carry out a psychological profile of J.k Rowling and of Severus Snape, character from the harry potter's heptalogy books, by Rowling. This profile is based on the review of the film material of the octology based on the books already mentioned and the film Magic beyond words, based on the life of J.K Rowling, furthermore of perspective of cognitive-postrational psychology. Among the main results found is the fact that J.K. Rowling and Severus Snape have the same attachment, but not the same OSP, owing to Rowling is obsessive OSP and Severus is depressive OSP, but that for its configuration of avoidant attachment if they are two sides of the same coin.

El estado epiléptico no convulsivo en el paciente geriátrico / Non convulsive epileptic status in the geriatric patient

Resumen: El estado epiléptico no convulsivo como diagnóstico diferencial de delirio es una enfermedad clínica cada más prevalente en la población geriátrica. Su manifestación se ha relacionado con múltiples factores de riesgo; la confusión es la manifestación clínica inicial en 49% de los pacientes, que interfiere en su calidad de vida y funcionalidad. El diagnóstico diferencial con el delirio es esencial debido a ser clínicamente similar, por lo que descartar factores predisponentes y precipitantes y corregir causas reversibles forma parte del manejo inicial. El electroencefalograma con correlación clínica establece el diagnóstico de acuerdo con el tipo de manifestación de estado epiléptico no convulsivo. El diagnóstico correcto permite su identificación y confirmación tempranas para otorgar el tratamiento anticonvulsivo ideal basado en la edad del paciente, comorbilidades y trastornos psiquiátricos acompañantes que permiten al paciente geriátrico disminuir su morbilidad y mortalidad y preservar su funcionalidad.

Abstract: The non-convulsive epileptic status (NCES) as a differential diagnosis of delirium is an increasingly prevalent clinical entity in the geriatric population. Its presentation has been linked to many risk factors and confusion is the initial clinical manifestation in up to 49% of the patients which interferes with their quality of life and conditions disability. Differential diagnosis with delirium is essential because its similarity, so discard predisposing and precipitating factors and correct reversible causes is part of the initial management. The electroencefalogram (EEG) with clinical correlation establishes the diagnosis according to the type of non-convulsive epileptic status presentation. Diagnostic suspicion allows the identification and early confirmation, for choosing the ideal anticonvulsant treatment based on the patient's age, comorbidities and psychiatric disorders in the geriatric patients, to reduce morbidity and mortality and preserve their functionality.

A Clinical Trial Comparing Tapering Doses of Buprenorphine with Steady Doses for Chronic Pain and Co-existent Opioid Addiction.

OBJECTIVES: Effective strategies are needed to manage individuals with chronic non-cancer pain and coexistent opioid addiction. This study compared opioid discontinuation and opioid replacement protocols. METHODS: We planned to enroll 60 individuals into an open-label trial who had been treated with opioids for chronic non-cancer pain, and who also had opioid addiction. Participants were randomly assigned to one of two 6-month treatment protocols of buprenorphine/naloxone sublingual tablets: 1) tapering doses for opioid weaning or "detoxification" (active comparator group) or 2) steady doses for opioid replacement (experimental group). They were followed monthly for the study outcomes: completion of the 6-month treatment protocol and self-reported pain control, physical functioning, alcohol consumption and illicit drug use. RESULTS: Enrollment was terminated after enrolling 12 participants because none of the 6 assigned to receive tapering doses could successfully complete the protocol (5 were given steady doses and 1 was admitted to an inpatient chemical dependency treatment program); whereas, of the 6 assigned to receive steady doses, 5 completed the protocol (1 withdrew). This difference between the 2 treatment conditions was significant (P = 0.015). Of the 10 participants who completed the 6 month follow-up, 8 reported improved pain control and physical functioning and 5 used alcohol and/or illicit drugs. CONCLUSIONS: We conclude that over 6 months, these participants with chronic pain and co-existent opioid addiction were more likely to adhere to an opioid replacement protocol than an opioid weaning protocol and that opioid replacement therapy with steady doses of buprenorphine/naloxone is associated with improved pain control and physical functioning.
