A qualitative study of career decision making among African and Asian international medical students in China: process, challenges, and strategies.

China hosts around 68,000 international medical students (IMSs) primarily from lower income countries in Africa and Asia, who have the potential to contribute to international medical services. Understanding how these IMSs make career decisions can help better address the issue of global medical workforce shortage. However, such research is limited. Our study aims to explore the career decision-making process of China-educated IMSs, the challenges they experienced and the strategies they employed.In this exploratory qualitative study, we conducted semi-structured interviews with IMSs educated in China in 2022 using purposeful sampling. Twenty virtual one-on-one interviews were conducted, and data were analysed through directed qualitative content analysis. Cognitive Information Processing (CIP) theory was applied as the guiding framework for organising and analysing the data.The career decision-making process of the participants generally followed the stages of decision-making cycle in CIP theory, with a combination of urgent migration decisions and specialisation considerations adding layers of complexity to their career trajectories. Identified challenges encompassed lack of knowledge about oneself and career options, lack of decision-making skills, concerns of contextual complexities that limited the career decision-making process, low motivation and negative thoughts. Specific challenges due to their role as IMSs arose, which were related to career information access, self-capability evaluation, degree accreditation, employment competitiveness and mental states. Participants' proposed strategies were categorised into personal and institutional aspects, providing insights into addressing these challenges.This study substantiates and expands the application of the CIP theory within the sphere of the particular cultural and educational context of IMSs educated in China. It highlights the significance of integrating migration decision-making into career guidance for IMSs, and contributes to the literature by proposing an evidence-based tiered career intervention programme for IMSs.

Specialty preferences of studying-abroad medical students from low- and middle-income countries.

BACKGROUND: This study explored the specialty preferences of China-educated international medical students (IMSs), who are mainly from low- and middle-income countries (LMICs) and constitute a potential medical workforce both for their home countries and foreign countries, and the influence of migration intentions on their specialty preferences. METHODS: A cross-sectional, questionnaire-based survey was conducted at 5 universities in China. The questionnaire link was distributed electronically among the IMSs at the 5 universities via emails. The questionnaire enquired IMSs' demographic information, migration intentions and their specialty preferences. The Chi-square test was applied to determine the influence of the respondent's gender, intention to practise in the home country and intention to practise in a high-income country on their specialty choices. The Chi-square test was also applied to determine the influence of the respondent's gender, year of study and country of origin on their preferences for generalist-orientated or non-generalist orientated specialties. RESULTS: Altogether, 452 IMSs returned their responses, yielding a response rate of 64.1%. Approximately half of the IMSs planned to not return to their home country. The most selected specialty was general surgery and the least selected specialty was physical medicine and rehabilitation. No significant differences were evident in most specialty preferences between those who intended to return home and those who intended to stay abroad. Among the IMSs having intentions of returning to their home country, male students tended to choose a generalist-orientated specialty, while female students tended to choose a non-generalist-orientated specialty. CONCLUSION: China-educated IMSs could play important roles in the primary care services as well as other shortage specialties both for their home countries or foreign countries. Therefore, it is recommended that governments in these countries plan migration and recruitment policies that cater for these studying-abroad medical students from LMICs, especially in this challenging time during the COVID-19 pandemic.

Functional analysis of RYR1 variants in patients with confirmed susceptibility to malignant hyperthermia.

BACKGROUND: A major bottleneck to the introduction of noninvasive presymptomatic diagnostic tests for the pharmacogenetic disorder malignant hyperthermia is the lack of functional data for associated variants. METHODS: We screened 50 genes having a potential role in skeletal muscle calcium homeostasis using the HaloPlex™ (Agilent Technologies, Santa Clara, CA, USA) target enrichment system and next-generation sequencing. Twenty-one patients with a history of a clinical malignant hyperthermia reaction together with a positive in vitro contracture test were included. Eight variants in RYR1 were subsequently introduced into the cDNA for the human ryanodine receptor gene and tested in cultured human embryonic kidney (HEK293) cells for their effect on calcium release from intracellular stores in response to the ryanodine receptor-1 agonist 4-chloro-m-cresol using fura-2 as calcium indicator. Each variant was subjected to in silico curation using the European Malignant Hyperthermia Group scoring matrix and ClinGen RYR1 variant curation expert panel guidelines. RESULTS: Potentially causative RYR1 variants were identified in 15 patients. Of these, two families carried two RYR1 variants, five variants had been previously reported as 'pathogenic', two variants had been previously reported as 'likely benign', and eight were of 'uncertain significance'. Of these eight variants, four showed hypersensitivity to 4-chloro-m-cresol. Three variants were reclassified as either 'pathogenic' or 'likely pathogenic'. Two were classified as 'benign', whilst three remained of 'uncertain significance'. CONCLUSIONS: Three (p.Tyr1711Cys, p.Val2280Ile, and p.Arg4737Gln) additional variants can be added to the list of RYR1 disease-associated variants managed by the European Malignant Hyperthermia Group. These can therefore be used diagnostically in the future. Three variants (p.Glu2348Gly, p.Asn2634Lys, and p.Arg3629Trp) that remained classified as of uncertain significance require further family studies or a different functional test to determine clinical relevance in malignant hyperthermia.

European Neuromuscular Centre consensus statement on anaesthesia in patients with neuromuscular disorders.

BACKGROUND AND PURPOSE: Patients with neuromuscular conditions are at increased risk of suffering perioperative complications related to anaesthesia. There is currently little specific anaesthetic guidance concerning these patients. Here, we present the European Neuromuscular Centre (ENMC) consensus statement on anaesthesia in patients with neuromuscular disorders as formulated during the 259th ENMC Workshop on Anaesthesia in Neuromuscular Disorders. METHODS: International experts in the field of (paediatric) anaesthesia, neurology, and genetics were invited to participate in the ENMC workshop. A literature search was conducted in PubMed and Embase, the main findings of which were disseminated to the participants and presented during the workshop. Depending on specific expertise, participants presented the existing evidence and their expert opinion concerning anaesthetic management in six specific groups of myopathies and neuromuscular junction disorders. The consensus statement was prepared according to the AGREE II (Appraisal of Guidelines for Research & Evaluation) reporting checklist. The level of evidence has been adapted according to the SIGN (Scottish Intercollegiate Guidelines Network) grading system. The final consensus statement was subjected to a modified Delphi process. RESULTS: A set of general recommendations valid for the anaesthetic management of patients with neuromuscular disorders in general have been formulated. Specific recommendations were formulated for (i) neuromuscular junction disorders, (ii) muscle channelopathies (nondystrophic myotonia and periodic paralysis), (iii) myotonic dystrophy (types 1 and 2), (iv) muscular dystrophies, (v) congenital myopathies and congenital dystrophies, and (vi) mitochondrial and metabolic myopathies. CONCLUSIONS: This ENMC consensus statement summarizes the most important considerations for planning and performing anaesthesia in patients with neuromuscular disorders.

Pre-operative exercise and pyrexia as modifying factors in malignant hyperthermia (MH).

Malignant hyperthermia (MH) is a life-threatening reaction triggered by volatile anesthetics and succinylcholine. MH is caused by mutations in the skeletal muscle ryanodine receptor (RYR1) gene, as is rhabdomyolysis triggered by exertion and/or pyrexia. The discrepancy between the prevalence of risk genotypes and actual MH incidence remains unexplained. We investigated the role of pre-operative exercise and pyrexia as potential MH modifying factors. We included cases from 5 MH referral centers with 1) clinical features suggestive of MH, 2) confirmation of MH susceptibility on Contracture Testing (IVCT or CHCT) and/or RYR1 genetic testing, and a history of 3) strenuous exercise within 72 h and/or pyrexia >37.5 °C prior to the triggering anesthetic. Characteristics of MH-triggering agents, surgery and succinylcholine use were collected. We identified 41 cases with general anesthesias resulting in an MH event (GA+MH, n = 41) within 72 h of strenuous exercise and/or pyrexia. We also identified previous general anesthesias without MH events (GA-MH, n = 51) in the index cases and their MH susceptible relatives. Apart from pre-operative exercise and/or pyrexia, trauma and acute abdomen as surgery indications, emergency surgery and succinylcholine use were also more common with GA+MH events. These observations suggest a link between pre-operative exercise, pyrexia and MH.

Barriers and facilitators to online medical and nursing education during the COVID-19 pandemic: perspectives from international students from low- and middle-income countries and their teaching staff.

BACKGROUND: The COVID-19 pandemic posed a huge challenge to the education systems worldwide, forcing many countries to provisionally close educational institutions and deliver courses fully online. The aim of this study was to explore the quality of the online education in China for international medical and nursing students from low- and middle-income countries (LMICs) as well as the factors that influenced their satisfaction with online education during the COVID-19 pandemic. METHODS: Questionnaires were developed and administered to 316 international medical and nursing students and 120 teachers at a university in China. The Chi-square test was used to detect the influence of participants' personal characteristics on their satisfaction with online education. The Kruskal-Wallis rank-sum test was employed to identify the negative and positive factors influencing the online education satisfaction. A binary logistic regression model was performed for multiple-factor analysis to determine the association of the different categories of influential factors-crisis-, learner-, instructor-, and course-related categories, with the online education satisfaction. RESULTS: Overall, 230 students (response rate 72.8%) and 95 teachers (response rate 79.2%) completed the survey. It was found that 36.5% of students and 61.1% of teachers were satisfied with the online education. Teachers' professional title, students' year of study, continent of origin and location of current residence significantly influenced the online education satisfaction. The most influential barrier for students was the severity of the COVID-19 situation and for teachers it was the sense of distance. The most influential facilitating factor for students was a well-accomplished course assignment and for teachers it was the successful administration of the online courses. CONCLUSIONS: Several key factors have been identified that affected the attitudes of international health science students from LMICs and their teachers towards online education in China during the COVID-19 pandemic. To improve the online education outcome, medical schools are advised to promote the facilitating factors and cope with the barriers, by providing support for students and teaching faculties to deal with the anxiety caused by the pandemic, caring for the state of mind of in-China students away from home, maintaining the engagement of out-China students studying from afar and enhancing collaborations with overseas institutions to create practice opportunities at students' local places.

Fatal awake malignant hyperthermia episodes in a family with malignant hyperthermia susceptibility: a case series.

PURPOSE: The present report of two fatal awake malignant hyperthermia (MH) episodes in an MH susceptible (MHS) family is intended to raise awareness among medical personnel and MHS individuals to the possibility of life-threatening non-anesthesia-triggered MH episodes and to provide a strong incentive for development of effective preventive measures. CLINICAL FEATURES: Two young athletic males (28 and 16 yr old), members of the same extended family with a history of anesthesia-related MH episodes and deaths, succumbed ten years apart on two different continents, with symptoms unrelated to anesthesia but strikingly similar to typical anesthetic-induced MH. Both suffered an abrupt surge in body temperature, tachycardia, tachypnea, muscle rigidity, hyperkalemia, and respiratory and metabolic acidosis. Despite aggressive resuscitation attempts, both developed cardiac arrest and died shortly upon arrival to hospital emergency departments. Autopsy analyses were negative for drugs, alcohol, or bacterial infection. Individual and familial genetic analyses revealed a novel, potentially pathogenic RYR1 variant (p.Gly159Arg) that co-segregates with the MHS phenotype in the family. Both fatal awake MH episodes are hypothesized to have been triggered by physical exertion compounded with a febrile illness that in one case was due to influenza type A. CONCLUSIONS: Life-threatening awake MH episodes may develop in some MHS individuals in the absence of anesthetic triggers. Potential triggers can be physical exertion in combination with a febrile illness. Malignant hyperthermia susceptible patients are recommended to be vaccinated against flu and restrict physical activities when febrile, wear an MH alert bracelet, and inform medical personnel of their MH history. Oral dantrolene is suggested to be available to MHS patients for administration with the early signs of awake MH.

RéSUMé: OBJECTIF: Ce compte-rendu de deux épisodes fatals d'hyperthermie maligne (HM) survenus en communauté, sans anesthésie, dans une famille susceptible à l'HM (SHM) a pour but premier de conscientiser le personnel médical et les personnes SHM quant au risque d'épisodes d'HM potentiellement fatals et non déclenchés par l'anesthésie. Notre deuxième objectif est d'encourager fortement la mise au point de mesures préventives efficaces. ÉLéMENTS CLINIQUES: Deux jeunes hommes sportifs (28 ans et 16 ans), membres de la même famille élargie ayant des antécédents d'épisodes d'HM et de décès liés à l'anesthésie, sont décédés à dix ans d'écart, sur deux continents, de symptômes non liés à l'anesthésie mais présentant une ressemblance frappante à une crise typique d'HM induite par l'anesthésie. Les deux hommes ont souffert d'une hausse rapide de leur température corporelle, de tachycardie, de tachypnée, de rigidité musculaire, d'hyperkaliémie et d'acidose respiratoire et métabolique. Malgré des tentatives vigoureuses de réanimation, les deux sont tombés en arrêt cardiaque et sont décédés peu après leur arrivée à l'urgence. Les analyses d'autopsie étaient négatives en ce qui touchait aux drogues, à l'alcool et aux infections bactériennes. Les analyses génétiques individuelles et familiales ont révélé une nouvelle variante du gène RYR1 potentiellement pathogène (p.Gly159Arg) qui est hérité en co-ségrégation avec le phénotype de SHM dans cette famille. On pense que ces deux épisodes fatals d'HM en éveil ont été provoqués par un effort physique combiné à une maladie fébrile qui, dans l'un des cas, était due à une influenza de type A. CONCLUSION: Des épisodes fatals d'HM en éveil peuvent survenir chez certaines personnes SHM en l'absence de déclencheurs anesthésiques. L'effort physique combiné à une maladie fébrile pourrait constituer un déclencheur potentiel. Les patients susceptibles à l'hyperthermie maligne sont encouragés à se faire vacciner contre l'influenza et à limiter leurs activités physiques lorsqu'ils souffrent de fièvre, à porter un bracelet d'alerte d'HM, et à informer le personnel médical de leurs antécédents d'HM. On suggère que du dantrolène par voie orale soit mis à la disposition des patients SHM afin d'être administré dès les premiers signes d'HM en éveil.

Functional Characterization of C-terminal Ryanodine Receptor 1 Variants Associated with Central Core Disease or Malignant Hyperthermia.

BACKGROUND: Central core disease and malignant hyperthermia are human disorders of skeletal muscle resulting from aberrant Ca2+ handling. Most malignant hyperthermia and central core disease cases are associated with amino acid changes in the type 1 ryanodine receptor (RyR1), the skeletal muscle Ca2+-release channel. Malignant hyperthermia exhibits a gain-of-function phenotype, and central core disease results from loss of channel function. For a variant to be classified as pathogenic, functional studies must demonstrate a correlation with the pathophysiology of malignant hyperthermia or central core disease. OBJECTIVE: We assessed the pathogenicity of four C-terminal variants of the ryanodine receptor using functional analysis. The variants were identified in families affected by either malignant hyperthermia or central core disease. METHODS: Four variants were introduced separately into human cDNA encoding the skeletal muscle ryanodine receptor. Following transient expression in HEK-293T cells, functional studies were carried out using calcium release assays in response to an agonist. Two previously characterized variants and wild-type skeletal muscle ryanodine receptor were used as controls. RESULTS: The p.Met4640Ile variant associated with central core disease showed no difference in calcium release compared to wild-type. The p.Val4849Ile variant associated with malignant hyperthermia was more sensitive to agonist than wild-type but did not reach statistical significance and two variants (p.Phe4857Ser and p.Asp4918Asn) associated with central core disease were completely inactive. CONCLUSIONS: The p.Val4849Ile variant should be considered a risk factor for malignant hyperthermia, while the p.Phe4857Ser and p.Asp4918Asn variants should be classified as pathogenic for central core disease.

Developments in Cooperative Learning: Review of Research / Avances en el aprendizaje cooperativo: Revisión de la investigación

Cooperative learning, where students work in small groups to accomplish shared goals, is widely recognized as a teaching strategy that promotes learning and socialization among students from kindergarten through college and across different subject domains. It has been used successfully to promote reading and writing achievements, understanding and conceptual development in science classes, problem-solving in mathematics, and higher-order thinking and learning to name just a few. It has been shown to enhance students’ willingness to work cooperatively and productively with others with diverse learning and adjustment needs and to enhance intergroup relations with those from culturally and ethnically different backgrounds. It has also been used as a teaching strategy to assist students to manage conflict and to help students identified as bullies learn appropriate interpersonal skills. In fact, it has been argued that cooperative learning experiences are crucial to preventing and alleviating many of the social problems related to children, adolescents, and young adults. There is no doubt that the benefits attributed to cooperative learning are widespread and numerous and it is the apparent success of this approach to learning that has led to it being acclaimed as one of the greatest educational innovations of recent times. The purpose of this paper is not only to review developments in research on cooperative learning but also to examine the factors that mediate and moderate its success. In particular, the review focuses on the types of student and teacher interactions generated and the key role talk plays in developing student thinking and learning, albeit though the expression of contrasting opinions or constructed shared meaning. The intention is to provide additional insights on how teachers can effectively utilize this pedagogical approach to teaching and learning in their classrooms

El aprendizaje cooperativo, donde los estudiantes trabajan en pequeños grupos para lograr metas compartidas, es ampliamente reconocido como una estrategia de enseñanza que promueve el aprendizaje y la socialización entre los estudiantes desde Educación Infantil hasta la Universidad y en las distintas materias curriculares. Se ha utilizado con éxito para favorecer el logro en la lectura y escritura, en la comprensión y el desarrollo conceptual en las clases de ciencias, en la resolución de problemas en matemáticas, en el pensamiento de orden superior y en el aprendizaje, por nombrar sólo algunos. Se ha comprobado que mejora la disposición de los estudiantes para trabajar de forma cooperativa y productiva con alumnos con distintas necesidades de aprendizaje y de ajuste y mejora las relaciones intergrupales entre grupos cultural y étnicamente diversos. También se ha utilizado como estrategia de enseñanza para ayudar a los estudiantes a manejar los conflictos y ayudar a los estudiantes identificados como agresores, a que aprendan habilidades interpersonales adecuadas. En efecto, se afirma que las experiencias de aprendizaje cooperativo son cruciales para prevenir y paliar muchos de los problemas sociales relacionados con los niños, adolescentes y adultos jóvenes. No hay duda de que los beneficios atribuidos al aprendizaje cooperativo son extensos y numerosos, y es el aparente éxito de este enfoque del aprendizaje lo que le ha llevado a ser reconocido como una de las mayores innovaciones educativas de los últimos tiempos. El objetivo de este trabajo es, no sólo revisar la evolución de la investigación sobre aprendizaje cooperativo, sino también, examinar los factores que median y moderan su éxito. Concretamente, la revisión se centra en los tipos de interacciones que se generan entre alumno y profesor y en el papel clave que desempeña el habla en el desarrollo del pensamiento y el aprendizaje del alumno, a través de la expresión de opiniones contrapuestas o la construcción de significados compartidos. La intención es proporcionar conocimientos adicionales sobre cómo los profesores pueden utilizar de manera eficaz este enfoque pedagógico para la enseñanza y el aprendizaje en sus aulas

The FRIENDS emotional health program for minority groups at risk.

BACKGROUND: Despite the existence of evidence-based interventions for promoting mental health in children, the number of children at risk remains high. One of the reasons is that such interventions are not reaching specific groups at risk such as low socioeconomic status and ethnic minority groups. This study evaluated an adaptation of a school-based psychosocial program for nonreferred students aged 11 to 12 years attending a multicultural school from a low socioeconomic status area. METHODS: The FRIENDS Program was adapted for a multicultural population. A quasi-experimental design was used, involving a pre/post-test, to evaluate the impact of the intervention on participants' outcomes on the Strengths and Difficulties Questionnaire (SDQ). Participants were divided into 2 categories ("at risk"/"not at risk") based on their scores in the SDQ at pre-test. Post-test data were collected to evaluate the overall effectiveness and acceptability of the program. RESULTS: Analyses showed significant improvement for the group initially identified as "at risk," with 30% of the students being no longer at risk after the intervention. Most students rated the intervention as being highly acceptable and useful. CONCLUSIONS: Adaptations to existing evidence-based programs for implementation with specific minority groups at risk represents a promising approach to promote emotional health in children.

Teachers' and students' verbal behaviours during cooperative and small-group learning.

BACKGROUND: Teachers play a critical role in promoting interactions between students and engaging them in the learning process. This study builds on a study by Hertz-Lazarowitz and Shachar (1990) who found that during cooperative learning teachers' verbal behaviours were more helpful to and encouraging of their students' efforts while during whole-class instruction, their verbal behaviours tended to be more authoritarian, rigid, and impersonal. AIM: This study seeks to determine if teachers who implement cooperative learning engage in more facilitative learning interactions with their students than teachers who implement group work only. The study also seeks to determine if students in the cooperative groups model their teachers' behaviours and engage in more positive helping interactions with each other than their peers in the group work groups. SAMPLES: The study involved 26 teachers and 303 students in Grades 8 to 10 from 4 large high schools in Brisbane, Australia. METHODS: All teachers agreed to establish cooperative, small-group activities in their classrooms for a unit of work (4 to 6 weeks) once a term for 3 school terms. The teachers were audiotaped twice during these lessons and samples of the students' language, as they worked in their groups, were also collected at the same time. RESULTS: The results show that teachers who implement cooperative learning in their classrooms engage in more mediated-learning interactions and make fewer disciplinary comments than teachers who implement group work only. Furthermore, the students model many of these interactions in their groups. CONCLUSIONS: The study shows that when teachers implement cooperative learning, their verbal behaviour is affected by the organizational structure of the classroom.

Quality of recovery from anesthesia in neurosurgical patients.

BACKGROUND: Factors influencing quality of recovery in cranial and spinal neurosurgical patients are not known, possibly because of lack of a suitable instrument. Therefore, the authors measured quality of recovery using the QoR-40 score (a 40-item questionnaire on quality of recovery from anesthesia). METHODS: With informed consent, 200 patients undergoing elective neurosurgery were recruited. The QoR-40 score, visual analog scores for pain and quality of recovery, and data on complications were collected over 90 days. The psychometrics of the QoR-40 were tested and regression models were developed to determine predictors of quality of recovery and postoperative pain. RESULTS: The QoR-40 score demonstrated significant responsiveness, validity, and reliability. In cranial surgery patients, QoR-40 scores were lower on days 1 and 2 than either preoperatively or on days 3, 30, and 90. In spinal surgery patients, QoR-40 scores were lower preoperatively and on days 1 and 2 than on days 3, 30, and 90. Longer duration of surgery, more complications, and higher visual analog scores for pain were predictors of poor quality of recovery on day 3. Cranial surgery patients had moderately severe pain on days 1 and 2, whereas spinal surgery patients reported moderate pain for the whole study period. Neurologic deficits were negatively correlated with QoR-40 scores in cranial and spinal surgery patients. CONCLUSIONS: The QoR-40 score is a useful instrument with which to assess quality of recovery in cranial and spinal surgery patients. Postoperative pain and neurologic deficits correlate with poor quality of recovery in these patients.
