    Artificial intelligence (AI) is an innovative tool with the potential to impact medical physicists' clinical practices, research, and the profession. The relevance of AI and its impact on the clinical practice and routine of professionals in medical physics were evaluated by medical physicists and researchers in this field. An online survey questionnaire was designed for distribution to professionals and students in medical physics around the world. In addition to demographics questions, we surveyed opinions on the role of AI in medical physicists' practices, the possibility of AI threatening/disrupting the medical physicists' practices and career, the need for medical physicists to acquire knowledge on AI, and the need for teaching AI in postgraduate medical physics programmes. The level of knowledge of medical physicists on AI was also consulted. A total of 1019 respondents from 94 countries participated. More than 85% of the respondents agreed that AI would play an essential role in medical physicists' practices. AI should be taught in the postgraduate medical physics programmes, and that more applications such as quality control (QC), treatment planning would be performed by AI. Half of the respondents thought AI would not threaten/disrupt the medical physicists' practices. AI knowledge was mainly acquired through self-taught and work-related activities. Nonetheless, many (40%) reported that they have no skill in AI. The general perception of medical physicists was that AI is here to stay, influencing our practices. Medical physicists should be prepared with education and training for this new reality.

    BACKGROUND: Academic failure is common among medical schools worldwide. However, the process behind this failure itself is underexplored. A deeper understanding of this phenomenon may avert the vicious cycle of academic failure. Hence, this study investigated the process of academic failure among medical students in Year 1.

    METHODS: This study employed a document phenomenological approach, which is a systematic process to examine documents, interpret them to attain understanding, and develop empirical knowledge of the phenomenon studied. Using document analysis, interview transcripts and reflective essays of 16 Year 1 medical students who experienced academic failure were analysed. Based on this analysis, codes were developed and further reduced into categories and themes. Thirty categories in eight themes were linked to make sense of the series of events leading to academic failure.

    RESULTS: One or more critical incidents commenced during the academic year, which led to possible resulting events. The students had poor attitudes, ineffective learning methods, health problems or stress. Students progressed to mid-year assessments and reacted differently to their results in the assessments. Afterwards, the students tried different types of attempts, and they still failed the end-of-year assessments. The general process of academic failure is illustrated in a diagram describing chronological events.

    CONCLUSION: Academic failure may be explained by a series of events (and consequences) of what students experience and do and how they respond to their experiences. Preventing a preceding event may prevent students from suffering these consequences.

    Purpose: Research has shown that many undergraduate students struggle with self-regulated learning (SRL) in clinical year as they are insufficiently supported by the staff in the early year to prepare them for the transition. Hence, this study aims to find out the SRL strategies and the approaches that could promote SRL among pre-clinical students in two medical schools.

    Method: This is a mixed-method study. The Motivated Strategies for Learning Questionnaire (MSLQ) was used to collect student SRL strategies while semi-structured interviews with faculty members and focus group discussions with students were used to gather data on the approaches that promote SRL. Student MSLQ was analysed using descriptive statistics while interviews were transcribed verbatim and thematically analysed.

    Results: A pilot using MSLQ with 413 students recorded a Cronbach's alpha of 0.928 for the questionnaire. The actual study involved 457 Years 1 & 2 students. Students from both institutions are motivated by the Task Value, and they use Elaboration and Organisation strategies the most in their pre-clinical year. Three themes emerged from the qualitative analysis of this study: characteristics of strategies that promote SRL, hindrance in promoting SRL, and opportunities in promoting SRL.

    Conclusions: Our findings indicate that students' intrinsic motivation is generally high in pre-clinical year. However, metacognition and critical thinking strategies will need to be enhanced among students. Despite knowing teaching and learning approaches could promote these strategies, many teachers are still not confident in doing so and hence training dang sharing best practices might be helpful in promoting SRL.

    Today most education institutions around the world have adopted the philosophy of outcome-based education. The emphasis in outcome-based education is achievement of outcomes; hence the curriculum should be designed in a way that it includes the components targeted specifically at achieving these outcomes. A discipline-based approach results in fragmentation of learning and lack of clinical applicability. Integrated teaching could be a solution to achieve required outcomes in a holistic way. Hence, the aim of this study was to develop, implement, and evaluate an integrated teaching module. Temporal coordination of the basic sciences, along with correlation of learned topics to clinical settings, was done in the first year of the undergraduate medical program. The module was evaluated by obtaining qualitative and quantitative feedback from students. Student assessment was conducted with a test that had case vignettes and multiple-choice questions. In addition, students' change in learning approaches and self-directed learning readiness were collected. Students' perception regarding the educational environment was also obtained. Analysis of the data showed positive feedback from the students regarding the integrated teaching. Students' average score in the test was 86%. There was a significant increase in the scores for the deep approach and self-directed learning readiness in the posttest compared with the pretest. Moreover, students were found to be satisfied with the educational environment. Evaluation of integrated teaching revealed that it was well accepted by the students. Moreover, it facilitated the achievement of the students' outcomes.

    Objectives: This study aimed to validate a Malaysian version of a revised learning space questionnaire, as well as to test the utility of the revised questionnaire as a tool to investigate learning space preferences in a Malaysian medical school.

    Methods:   This is a cross-sectional survey. A convenient sample of 310 preclinical students of a public medical school in Malaysia were invited to participate. Validation data were collected using a revised 40-item, 5-point Likert scale learning space questionnaire.  The questionnaires were administered online via a student e-learning platform.  Data analysis was conducted using IBM SPSS version 24.  Exploratory factor analysis was conducted to examine the factor structure of the revised questionnaire to provide evidence for construct validity.  To assess the internal consistency of the revised questionnaire, Cronbach's alpha coefficients (α) were computed across all the items as well as for items within each of the factor.

    Results: A total of 223 (71.94%) preclinical students completed and returned the questionnaire. In the final analysis, exploratory factor analysis with principal axis factoring and an oblimin rotation identified a six-factor, 20-item factor solution. Reliability analysis reported good internal consistency for the revised questionnaire, with an overall Cronbach's alpha of 0.845, and Cronbach's alpha ranging from 0.800 to 0.925 for the six factors.

    Conclusions:   This study established evidence for the construct validity and internal consistency of the revised questionnaire.  The revised questionnaire appears to have utility as an instrument to investigate learning space preferences in Malaysian medical schools.

    INTRODUCTION: During the coronavirus disease 2019 (COVID-19) pandemic, the use of virtual consultations has accelerated to ensure continued access to healthcare despite lockdowns and physical distancing measures. We aimed to determine the knowledge (awareness) of, attitude (acceptability) to, and practice (exposure) [KAP] of virtual consultations (VC), the demographic factors associated with poor KAP, and the correlation between the three KAP domains.

    METHODS: A cross-sectional study, using a convenience sampling technique, was conducted from 13 September, 2021 to 28 November, 2021. We designed a 45-item VC KAP questionnaire. This was distributed to outpatient users attending cardiovascular, dermatology, geriatrics, haematology, endocrine, respiratory, gastroenterology, rheumatology, or neurology clinics at the University Malaya Medical Centre. It was completed during face-to-face, online, or telephone interviews. The data were analysed using SPSS version 24.0. Binary logistic regression was used to determine the demographic factors associated with KAP. Correlation between KAP domains was determined using Spearman's rho (r). A p-value of <0.05 was considered statistically significant.

    RESULTS: A total of 366 questionnaires were completed. Knowledge (awareness), attitude (acceptability), and practice (exposure) were considered good in 69.7%, 80.9%, and 24.6% of participants, respectively. There were no significant relationships between age, gender, ethnicity, and duration of hospital attendance (years) with knowledge (awareness), attitude (acceptability), and practice (exposure). A moderate positive correlation was seen between knowledge (awareness) and attitude (acceptability) (Attitude total [Atotal]) (r = 0.48, p<0.001), with no significant correlation between knowledge (awareness) and practice (exposure) (r = 0.04, p = 0.45), and attitude (acceptability) (Atotal) and practice (r = 0.01, p = 0.82).

    CONCLUSION: Overall, outpatient clinic users had good knowledge (awareness) of and were receptive towards VC but had poor practice (exposure). More opportunities for VC use in healthcare can increase exposure and subsequent utilisation. Interventions to increase the effectiveness of VC use should be explored in future studies.

    BACKGROUND: Poor academic performance and failure can cause undesired effects for students, schools, and society. Understanding why some students fail while their peers succeed is important to enhance student performance. Therefore, this study explores the differences in the learning process between high- and low-achieving pre-clinical medical students from a theory of action perspective.

    METHODS: This study employed a qualitative instrumental case study design intended to compare two groups of students-high-achieving students (n = 14) and low-achieving students (n = 5), enrolled in pre-clinical medical studies at the Universiti Malaya, Malaysia. Data were collected through reflective journals and semi-structured interviews. Regarding journaling, participants were required to recall their learning experiences of the previous academic year. Two analysts coded the data and then compared the codes of high- and low-achieving students. The third analyst reviewed the codes. Themes were identified iteratively, working towards comparing the learning processes of high- and low-achieving students.

    RESULTS: Data analysis revealed four themes-motivation and expectation, study methods, self-management, and flexibility of mindset. First, high-achieving students were more motivated and had higher academic expectations than low-achieving students. Second, high-achieving students adopted study planning and deep learning approaches, whereas low-achieving students adopted superficial learning approaches. Third, in contrast to low-achieving students, high-achieving students exhibited better time management and studied consistently. Finally, high-achieving students proactively sought external support and made changes to overcome challenges. In contrast, low-achieving students were less resilient and tended to avoid challenges.

    CONCLUSION: Based on the theory of action, high-achieving students utilize positive governing variables, whereas low-achieving students are driven by negative governing variables. Hence, governing variable-based remediation is needed to help low-achieving students interrogate the motives behind their actions and realign positive governing variables, actions, and intended outcomes.Key MessagesThis study found four themes describing the differences between high- and low-achieving pre-clinical medical students: motivation and expectation, study methods, self-management, and flexibility of mindset.Based on the theory of action approach, high-achieving pre-clinical medical students are fundamentally different from their low-achieving peers in terms of their governing variables, with the positive governing variables likely to have guided them to act in a manner beneficial to and facilitating desirable academic performance.Governing variable-based remediation may help students interrogate the motives of their actions.

    BACKGROUND: Virtual consultation is a synchronous mode of telemedicine provided remotely via information and communication technology. The projected growth of digitalization in healthcare delivery, however, necessitates medical student training in virtual consultation (VC) to ensure safe and effective patient care. This study describes the implementation and preliminary evaluation of a competency-based VC training module for undergraduate medical students.

    METHODS: A newly developed six-week VC module was implemented online through asynchronous microlearning and synchronous simulation-based experiential learning modalities. Clinical students in years 4 and 5 and fresh graduates, who had not started pre-registration house officer or residency programmes, were invited to participate. Training outcomes using checklist-based video-recorded assessments of VC encounters between medical students and simulated patients were compared. Each video was independently assessed by two facilitators trained in VC teaching and assessment, using a direct observed virtual consultation skills checklist derived from established VC competencies. The participants completed course evaluations electronically as additional outcome measures.

    RESULTS: Fifty-two clinical phase medical students and alumni completed both the instructional and practical phases of this module. Altogether, 45 (95.7%) students found the module beneficial, and 46 (95.9%) reported increased self-efficacy for conducting VC. In total, 46 (95.9%) students would recommend the course to others. Post-test results showed a significant increase in the students' abilities to conduct a VC (t-test = 16.33, p

    BACKGROUND: Uropathogenic Escherichia coli (UPEC) is the predominant agent causing various categories of complicated urinary tract infections (cUTI). Although existing data reveals that UPEC harboured numerous virulence determinants to aid its survival in the urinary tract, the reason behind the occurrence of differences in the clinical severity of uninary tract infections (UTI) demonstrated by the UPEC infection is poorly understood. Therefore, the present study aims to determine the distribution of virulence determinants and antimicrobial resistance among different phylogroups of UPEC isolated from various clinical categories of cUTI and asymptomatic bacteriuria (ASB) E. coli isolates. The study will also attempt a relational analysis of the genotypic characteristics of cUTI UPEC and ASB E. coli isolates.

    METHODS: A total of 141 UPEC isolates from cUTI and 160 ASB E. coli isolates were obtained from Universiti Malaya Medical Centre (UMMC). Phylogrouping and the occurrence of virulence genes were investigated using polymerase chain reaction (PCR). Antimicrobial susceptibility of the isolates to different classes of antibiotics was determined using the Kirby Bauer Disc Diffusion method.

    RESULTS: The cUTI isolates were distributed differentially among both Extraintestinal Pathogenic E. coli (ExPEC) and non-ExPEC phylogroups. Phylogroup B2 isolates were observed to possess the highest average aggregative virulence score (7.17), a probable representation of the capability to cause severe disease. Approximately 50% of the cUTI isolates tested in this study were multidrug resistant against common antibiotics used to treat UTI. Analysis of the occurrence of virulence genes among different cUTI categories demonstrated that UPEC isolates of pyelonephritis and urosepsis were highly virulent and had the highest average aggregative virulence scores of 7.80 and 6.89 respectively, compared to other clinical categories. Relational analysis of the occurrence of phylogroups and virulence determinants of UPEC and ASB E. coli isolates showed that 46.1% of UPEC and 34.3% of ASB E. coli from both categories were distributed in phylogroup B2 and had the highest average aggregative virulence score of 7.17 and 5.37, respectively. The data suggest that UPEC isolates which carry virulence genes from all four virulence genes groups studied (adhesions, iron uptake systems, toxins and capsule synthesis) and isolates from phylogroup B2 specifically could predispose to severe UTI involving the upper urinary tract. Therefore, specific analysis of the genotypic characteristics of UPEC could be further explored by incorporating the combination of virulence genes as a prognostic marker for predicting disease severity, in an attempt to propose a more evidence driven treatment decision-making for all UTI patients. This will go a long way in enhancing favourable therapeutic outcomes and reducing the antimicrobial resistance burden among UTI patients.

    BACKGROUND: Self-regulated learning (SRL) is an important contributing element to the academic success of students. Literature suggests that the understanding of SRL among medical students is obscure as there is still some uncertainty about whether high performing medical students use SRL. This study explored the characteristics of high performing medical students from the SRL perspective to gain a better understanding of the application of SRL for effective learning.

    METHODS: Twenty-one students who scored at the 90th percentile in written knowledge-based assessment consented to participate in this study. Each student wrote a guided reflective journal and subsequently attended a semi-structured interview. Students were prompted to explain the rationales for their answers. The data were then analysed using thematic analysis to identify patterns among these students from the SRL perspective. Two coders analysed the data independently and discussed the codes to reach a consensus.

    RESULTS: High performing students set goals, made plans, and motivated themselves to achieve the goals. They put consistent efforts into their studies and applied effective learning strategies. They also employed coping mechanisms to deal with challenges. High performing students regularly evaluated their performance and adopted new strategies.

    CONCLUSIONS: This study reported that high performing students applied SRL and described the rationales of practice. Medical schools could design SRL-driven interventions to enhance the learning experiences of medical students. Recommendations are made for students on how to apply SRL.

    Current feedback models advocate learner autonomy in seeking, processing, and responding to feedback so that medical students can become feedback-literate. Feedback literacy improves learners' motivation, engagement, and satisfaction, which in turn enhance their competencies. However, there is a lack of an objective method of measuring medical student feedback literacy in the empirical literature. Such an instrument is required to determine the level of feedback literacy amongst medical students and whether they would benefit from an intervention. Therefore, this research protocol addresses the methodology aimed at the development of a comprehensive instrument for medical student feedback literacy, which is divided into three phases, beginning with a systematic review. Available instruments in health profession education will be examined to create an interview protocol to define medical students' feedback literacy from the perspectives of medical students, educators, and patients. A thematic analysis will form the basis for item generation, which will subsequently undergo expert validation and cognitive interviews to establish content validity. Next, we will conduct a national survey to gather evidence of construct validity, internal consistency, hypothesis testing, and test-retest reliability. In the final phase, we will distribute the instrument to other countries in an international survey to assess its cross-cultural validity. This protocol will help develop an instrument that can assist educators in assessing student feedback literacy and evaluating their behavior in terms of managing feedback. Ultimately, educators can identify strengths, and improve communication with students, as well as feedback literacy and the feedback process. In conclusion, this study protocol outlined a systematic, evidence-based methodology to develop a medical student feedback literacy instrument. This study protocol will not only apply to medical and local cultural contexts, but it has the potential for application in other educational disciplines and cross-cultural studies.

    PURPOSE: We present the implementation of e-learning in the Master of Medical Physics programme at the University of Malaya during a partial lockdown from March to June 2020 due to the COVID-19 pandemic.

    METHODS: Teaching and Learning (T&L) activities were conducted virtually on e-learning platforms. The students' experience and feedback were evaluated after 15 weeks.

    RESULTS: We found that while students preferred face-to-face, physical teaching, they were able to adapt to the new norm of e-learning. More than 60% of the students agreed that pre-recorded lectures and viewing videos of practical sessions, plus answering short questions, were beneficial. Certain aspects, such as hands-on practical and clinical experience, could never be replaced. The e-learning and study-from-home environment accorded a lot of flexibility. However, students also found it challenging to focus because of distractions, lack of engagement and mental stress. Technical problems, such as poor Internet connectivity and limited data plans, also compounded the problem.

    CONCLUSION: We expect e-learning to prevail in future. Hybrid learning strategies, which includes face-to-face classes and e-learning, will become common, at least in the medical physics programme of the University of Malaya even after the pandemic.
