RESUMO

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is a major cause of global illness and death, most commonly caused by cigarette smoke. The mechanisms of pathogenesis remain poorly understood, limiting the development of effective therapies. The gastrointestinal microbiome has been implicated in chronic lung diseases via the gut-lung axis, but its role is unclear. DESIGN: Using an in vivo mouse model of cigarette smoke (CS)-induced COPD and faecal microbial transfer (FMT), we characterised the faecal microbiota using metagenomics, proteomics and metabolomics. Findings were correlated with airway and systemic inflammation, lung and gut histopathology and lung function. Complex carbohydrates were assessed in mice using a high resistant starch diet, and in 16 patients with COPD using a randomised, double-blind, placebo-controlled pilot study of inulin supplementation. RESULTS: FMT alleviated hallmark features of COPD (inflammation, alveolar destruction, impaired lung function), gastrointestinal pathology and systemic immune changes. Protective effects were additive to smoking cessation, and transfer of CS-associated microbiota after antibiotic-induced microbiome depletion was sufficient to increase lung inflammation while suppressing colonic immunity in the absence of CS exposure. Disease features correlated with the relative abundance of Muribaculaceae, Desulfovibrionaceae and Lachnospiraceae family members. Proteomics and metabolomics identified downregulation of glucose and starch metabolism in CS-associated microbiota, and supplementation of mice or human patients with complex carbohydrates improved disease outcomes. CONCLUSION: The gut microbiome contributes to COPD pathogenesis and can be targeted therapeutically.

RESUMO

BACKGROUND: Medical education offers the foundational base for future healthcare professionals, with basic sciences playing a pivotal role in providing essential knowledge and skills for clinical practice. However, the long-term retention and application of this knowledge in clinical practice remain a significant challenge. This systematic review synthesised global evidence from diverse studies on the short / long-term retention and clinical application of basic sciences among medical doctors. METHODS: A comprehensive search was conducted across six databases, including Web of Science, Scopus, Medline, CINAHL, Emcare, and Informit. The review included studies that encompassed a variety of study designs, participant groups, and educational interventions. The Quality Assessment with Diverse Studies (QuADS) tool was utilised to assess the quality of the reviewed studies. RESULTS: A total of 10 studies were included in the review. The findings revealed that rehearsals significantly optimise the retention of basic science knowledge among medical practitioners. Retention varied by discipline, with medical practitioners retaining more knowledge in anatomy (mean scores ranging from 45.0 to 82.9%), while microbiology had the lowest retention score (39.1%). Factors influencing retention included age, gender, and curriculum type. Educational interventions such as targeted courses, integration of basic sciences with clinical skills, generative retrieval and continuous quality improvement in the curriculum were found to enhance both knowledge retention and clinical reasoning. The concept of 'encapsulated knowledge' demonstrates that integrated basic science knowledge helps in synthesising clinical presentations, reducing the need for detailed recall as clinical experience increases. The reviewed studies primarily involved interns and surgeons, leaving a significant gap in research for specialties like internal medicine and primary care/ general practice. CONCLUSION: Detailed retention of basic science knowledge may diminish over time; however, the conceptual framework remains essential for ongoing learning and clinical reasoning. This review's findings highlight the need for specialised educational interventions to improve long-term retention. Continuous professional development and targeted educational techniques are vital for maintaining clinical competence and applying basic science knowledge effectively throughout a medical career. Further research is needed to address gaps in specialty-specific knowledge application and the impact of different instructional methods.

RESUMO

BACKGROUND: Basic sciences are crucial for clinical medicine, yet studies focusing on their perceived utility among general practitioners (GPs) are sparse. Considering the broad scope of GPs' practice, an in-depth understanding of basic sciences is fundamental for making informed clinical decisions. This study evaluated GP registrars' retention and perceptions of the utility of basic sciences in clinical practice. METHODS: Using sequential explanatory mixed methods study design, knowledge retention was assessed by a multiple-choice question (MCQ) examination followed by interviews on the perception of the relevance and utility of basic sciences among GP registrars at James Cook University's (JCU) General Practice Training (GPT) program. Descriptive and inferential statistical analyses were conducted on the MCQ exam data, while thematic analysis was employed for the qualitative interview data. RESULTS: Sixty-one GP registrars participated in the MCQ exam, while 11 of them were involved in the interviews. The highest mean score was obtained in biochemistry (75.1 ± 2.23) while the lowest mean score was in anatomy (56.07 ± 3.16). Key performance predictors included the formative clinical examination scores (ß = 0.83, 95% CI: 0.45 to 1.2, p < 0.001) and gender (ß = -9.7, 95% CI: -17 to -2.3, p = 0.011). The qualitative data analysis revealed five themes, including the backbone of clinical medicine, varying utility over time and by specialty, clinical synthesis integrates encapsulated knowledge, professional pressures hinder revisitation of knowledge and knowledge renewal enhances updates. CONCLUSION: Basic sciences were considered relevant in clinical practice. Development of continuing professional development (CPDs) sessions and clinically relevant online resources were measures proposed to enhance the retention of knowledge. Future research could focus on innovative educational strategies for GPs.

RESUMO

BACKGROUND: It is generally agreed that basic and clinical sciences should be integrated throughout the undergraduate medical education, however, there is still need for continued formal integration of basic sciences into clinical clerkship in many medical schools across the globe. METHODS: Utilizing Kern's Six-Step Model of Instructional Design, we aimed to develop an intervention that would facilitate cognitive integration of basic and clinical sciences. After problem identification and targeted needs assessment through focused group discussion with the students and faculty, objectives were devised with an implementation plan of using flipped class approach to develop a content-focused and learner-centered teaching strategy. This intervention was piloted in the 2-week cardiology clerkship in Year 5. Evaluation of the content, integration, student and faculty experiences were recorded through in-depth interviews, FGDs and a formative MCQ test. RESULTS: Flipped classroom based integrated sessions were successfully developed. The implementation phase was met with challenges that primarily stemmed from the diverse teaching styles among faculty members, hesitance to deviate from conventional practices, variations in clinic timings, and demanding schedules. Noteworthy observations were in terms of ownership of the project, the need for faculty development in modern student-centered teaching pedagogies, opportunities for content improvement, scheduling of sessions, and suggestion of revisiting fundamental concepts in basic sciences through a brief boot camp-style session at the onset of the clerkship. The role of flipped case model and clinical cases in integrating basic sciences into clinical sciences were appreciated by the students. Standardization in teaching practices was identified as the major challenge by the faculty. CONCLUSIONS: A functional, learner-centered framework of cognitive integration of basic sciences in clinical sciences curriculum of cardiology rotation was developed with a potential to be implemented in other clerkship rotations.

RESUMO

BACKGROUND: The evidence underpinning caries management for children has progressed dramatically over the past 20 years. Anecdotally, this is not reflected in the teaching provided to undergraduate dental students, with the ongoing teaching of outdated methods within some dental schools. AIM: To capture the current undergraduate teaching provision and clinical treatment experience requirement relative to caries management in paediatric dentistry in UK dental schools. DESIGN: Cross-sectional analysis of current teaching methods on paediatric caries management was obtained using a piloted online data collection form. Question content included current caries teaching methods, assessment of student exposure and competence. The results were analysed descriptively. RESULTS: Of the 16 UK dental schools, 14 participated. Discrepancy in teaching content was apparent. Many schools (n = 9) taught biological caries management through therapeutic fissure sealants, yet this was not reflected in assessment and clinical requirements. Some schools (n = 4) taught amalgam placement in children, and most (n = 12) operatively taught treatments that would no longer be routinely provided in general dental practice in the UK, including primary tooth pulpotomy. CONCLUSION: There is substantial variation in the paediatric caries management techniques that are taught across UK dental schools, demonstrating a need for a national consensus to address these disparities.

RESUMO

Background: Due to the changing conditions of education, research, and treatment in the world, especially the recent pandemic, and more use of virtual space, there is a need for evaluation of digital professionalism in faculty members as the most influential people who have a direct and deep impact on the next generation. Methods: In this analytical cross-sectional study that was conducted in 2023 on 149 faculty members of Iran University of Medical Sciences, they were invited to participate in the study through various methods (SMS, E-mail, and media messages). The link to the Persian standardized questionnaire was made available for participants. If a person received less than 70% of the score in each area, he/she would receive solutions to improve his/her situation in that area at the end of answering the questions. The self-administered questionnaire has 5 fields and 33 questions. Maximum scores were 10 points. Spearman and Pearson correlation coefficients and statistical tests consisting of chi-square, t-test, Mann-Whitney U, one-way ANOVA, and Kruskal-Wallis H were used in the analysis. Results: The mean overall score of people in principles of digital professionalism was 0.8. Women and basic sciences faculties had a significantly better status than men and clinical faculties in the principles of digital professionalism as a whole (P = 0.001 and P = 0.049, respectively). The domain of "knowledge management and information literacy" had significantly lower scores in professors in comparison with other degree (instructors, assistant professors, and associate professors (P = 0.039). Conclusion: The mean score of the principles of digital professionalism is acceptable at 80%. Coherent, timely, and up-to-date training to ensure the effective, safe and appropriate use of digital technology, especially for men, professors and clinical faculty members who had a lower score than others, should be done.

RESUMO

The COVID-19 pandemic had a disruptive effect on higher education. A critical question is whether these changes affected students' learning outcomes. Knowledge gaps have consequences for future learning and may-in health professionals' education-also pose a threat to patient safety. Current research has shortcomings and does not allow for clear-cut interpretation. Our context is instruction in human physiology in an undergraduate medical program from high stakes end of term examinations. The sequence of imposed measures to slow the COVID-19 pandemic created a natural experiment, allowing for comparisons in performance during in-person versus remote instruction.In a two-factorial design, mode of instruction (in-person vs. remote) and mode of assessment (in-person vs. remote) were analyzed using both basic (non-parametric statistics, T-tests) and advanced statistical methods (linear mixed-effects model; resampling techniques). Test results from a total of N = 1095 s-year medical students were included in the study.We did not find empirical evidence of knowledge gaps; rather, students received comparable or higher scores during remote teaching. We interpret these findings as empirical evidence that both students and teachers adapted to pandemic disruption in a way that did not lead to knowledge gaps.We conclude that highly motivated students had no reduction in academic achievement. Moreover, we have developed an accessible digital exam system for secure, fair, and effective assessments which is sufficiently defensible for making pass/fail decisions.

RESUMO

Background: The instructor is one of the key factors in attaining educational goals in medical education, and the instructor's competencies facilitate students' educational achievement. The present study is an attempt to explain the experiences of faculty members and students of characteristics of competent professors who play an influential role in the academic achievement of basic medical sciences students in universities of medical sciences across the country. Methods: The present study is a conventional qualitative content analysis. Fifteen faculty members and students of medicine from Iranian universities of medical sciences from different regions of the country were selected using a purposive and then theoretical sampling. A semi-structured interview was used for data collection. Results: In this study, four themes and nine sub-themes were extracted from interviews. The themes included "clinical knowledge", "teaching competency", "monitoring students' performance", and "cognitive-psychological arousal". The sub-themes were "clinical knowledge' including "Non-applied teaching of basic sciences and unfamiliarity of instructors of basic sciences with the clinic"; "teaching competency" including "having instructional design skills, teaching based on the psychology of learning, and professional development"; "monitoring students' performance" including "fair evaluation and valid evaluation", and "cognitive-psychological arousal" including "student support and reinforcement". Conclusion: The present study identified the important characteristics of the competencies of professors of basic medical sciences working in Iranian medical universities. The competency of professors is essential in promoting students' educational achievement and training efficient and professional students in the field of medicine to render quality health services. The results of this study will assist administrators and educational policymakers in planning for the promotion of professors and medical education.

RESUMO

BACKGROUND: Characteristics of laboratory findings of COVID-19 patients are of great significance for diagnosis and treatment. Studies that have analysed the variations in hepatic profile in correlation with the inflammatory markers in SARS-CoV-2 are limited. METHODS: We retrospectively analysed liver function tests and inflammatory markers of 170 admitted patients with confirmed COVID-19 in the tertiary care centre, Post Graduate Institute of Medical Education and Research (PGIMER), India, using Roche Cobas Autoanalyzer. RESULTS: Number of patients with normal liver enzyme levels were 63 (41.5%), while with raised levels of any of the liver enzymes were 89 (58.5%), out of which 43 (48.31%) had liver injury which manifested as increased severity in terms of intensive care unit (ICU) requirement (p=0.0005). Significantly raised levels of liver enzymes and liver injury were observed with age (p<0.0001) and in males (p=0.004). Significantly decreased levels of albumin and total proteins and increased levels of total bilirubin (p<0.0001) were seen in patients with abnormal liver enzyme levels and liver injury as compared to patients with normal levels. Significant increase in the levels of alanine transaminase and gamma-glutamyl transferase was seen on the 7th day, CRP and ferritin (p<0.0001) peaks were observed on 2nd and 3rd day respectively. A significant positive correlation was found between the levels of these inflammatory markers and liver function parameters. CONCLUSIONS: More than half of patients admitted to the hospital with SARS-CoV-2 infection had an abnormal liver function which was found to be associated with raised levels of inflammatory markers. Significantly higher proportions of patients with abnormal liver function were elderly and males and were at higher risk of progressing to severe disease.

RESUMO

One of the many challenges facing doctors in training during the COVID-19 pandemic was a significant reduction in postgraduate medical education in the form of formal teaching. Consequently, we sought to provide a blended and asynchronous teaching programme that would be delivered to anaesthetic trainees preparing for their postgraduate examinations. Six sessions of 90-minute duration were delivered during the months July, August and September 2020. Each of the six sessions was delivered live using a variety of online educational tools in addition to traditional didactic-style teaching by the presenters. Participants submitted requests for topics to be covered by the presenters in the final of the six sessions. The sessions were recorded and later uploaded onto an online educational learning platform for viewing at the participants' discretion. The live nature of the sessions ensured participant interaction and a sense of community that trainees had come to expect from previous face-to-face teaching sessions prior to the COVID-19 pandemic. Evaluation was via qualitative and quantitative means using preset questions using the Likert scale and a free-text comments box. The results demonstrated positive feedback across all sessions with particular relevance to the interactive element of the course, the content and delivery. This article describes the requirement for a method of continuing postgraduate medical education in an era where traditional face-to-face teaching is not possible and how the introduction of various innovative educational applications and resources can be used to further postgraduate medical education in the future.

RESUMO

Increasingly, basic science educators at medical and health science programs are faced with the challenge of delivering fundamental science content using evidence-based pedagogical approaches that build students' fund of knowledge while also supporting their development as self-regulated learners. This has led to an increased use of active learning-based pedagogies such as flipped classroom teaching. However, there are many open questions about the conditions necessary for successful flipped classroom sessions. In particular, the role of student compliance (i.e., participation, engagement, attendance) in mediating performance needs to be evaluated. This is especially important in accelerated curricula where multiple basic science disciplines are integrated together in pass-fail courses, presenting challenges to both students' time and cognitive load. Data on prematriculation performance, in-class participation, weekly quiz performance, and summative assessment performance from three cohorts of medical students (n = 146) at a new medical school were collected and analyzed. We found that historically high-performing students more readily participated in flipped classroom application sessions compared with historically lower-performing students. Correlational analysis of performance on weekly formative quizzes and the summative course exam was not related to in-class participation. However, performance on weekly formative quizzes played the most significant role in students' performance on summative exams. Efforts to understand the benefits of in-class participation beyond short-term assessment performance, such as long-term knowledge retention or development of noncognitive skills, should be undertaken to justify using such time- and human resource-intensive pedagogies.NEW & NOTEWORTHY This study explores the use of flipped classroom teaching in a voluntary and accelerated medical school course. We found that historically high-performing students attend class, whereas historically low-performing students do not attend class as readily. Formative assessment performance appears to be more important than participation in determining the final grade. Correlation of high performance (>90%) with participation may differentiate students who excel in our curriculum from those who simply pass with superficial knowledge.

RESUMO

BACKGROUND: Undergraduate dental basic research education (UDBRE) is broadly regarded as an important approach for cultivating scientific research talent. This scoping review aims to summarize the current status of UDBRE in terms of educational goals, teaching program and content, assessment system, training outcomes, barriers, and reflections. METHODS: The authors performed a systematic literature search in PubMed, Web of Science, and Education Resources Information Center (ERIC) to identify peer-reviewed articles written in English from their inception to January 29, 2021. Articles were reviewed and screened according to the inclusion and exclusion criteria. Related data from the included publications were then collected and summarized. RESULTS: The authors searched 646 publications and selected 16 articles to include in the study. The education goals included cultivating five major dental basic research capabilities (n=10, 62.5%) and developing interest in basic research (n=2, 12.5%). As for the teaching program, the mentor-guided student research project was the most popular (n=11, 68.8%), followed by didactic courses (n=5, 31.3%), experimental skills training (n=1, 6.3%), and the combination of the above forms (n=3, 18.8%). However, the assessment system and training outcome diverged. Existing evidence showed that UDBRE reached satisfying education outcomes. Barriers included excessive curriculum burden (n=2, 12.5%), tutor shortage (n=3, 18.8%), lack of financial support (n=5, 31.3%), and inadequate research skills and knowledge (n=5, 31.3%). CONCLUSIONS: Although efforts were made, the variation between studies revealed the immature status of UDBRE. A practical UDBRE education system paradigm was put forward. Meanwhile, more research is required to optimize a robust UDBRE system with clear education goals, well-designed teaching forms, and convincing assessment systems.

RESUMO

BACKGROUND: Complex regional pain syndrome (CRPS) is a heterogenous and poorly understood condition that can be provoked by quite minor injuries. The symptoms and signs of CRPS persist, long after the patient has recovered from the inciting event. In some cases, there is a clear association with a peripheral nerve injury. The degree of disability produced by CRPS is often out of proportion to the scale of the original insult and the condition is associated with protracted recovery times and frequent litigation. METHODS: We have performed a PubMed literature search, referenced landmark papers in the field and included a national expert in peripheral nerve injury and repair in our team of authors. RESULTS AND CONCLUSIONS: The diagnostic criteria for CRPS have changed repeatedly over the last two centuries and much of the historical literature is difficult to compare with more recent research. In this review article, we consider how our understanding of the condition has evolved and discuss its pathogenesis, its apparent heterogenicity and the various investigations and treatments available to the clinician.

RESUMO

INTRODUCTION: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been caused the greatest pandemic of our century. Many of the deaths related to it are due to a systemic inflammatory response, which has been called 'cytokine storm'. OBJECTIVES: We developed a comprehensive review of the pathophysiology mechanisms of COVID-19 and of the rationale for drugs and therapeutics that have been tested in clinical trials. METHODS: A narrative review of the literature was conducted using PubMed, SciELO, Bireme, Google Scholar and ClinicalTrials. RESULTS: SARS-CoV-2 has evolutive mechanisms that made it spread all around the globe, as a higher latency period and a lesser lethality than other coronaviruses. SARS-CoV-2 causes a delay in the innate immune response and it disarranges the immune system leading to an overwhelming inflammatory reaction (the 'cytokine storm'). In this scenario, high levels of interleukins (IL), notably IL-6 and IL-1, create a positive feedback of chemokines and immune responses, and powers pulmonary and systemic tissue damage, leading to capillary leakage and SARS, the main cause of death in patients with COVID-19. On 17 July 2020, there were 1450 entries on ClinicalTrials.gov of ongoing studies on COVID-19. The mechanisms of the main therapeutic approaches were comprehensively reviewed throughout the text. Therapies focus on blocking viral entry (remdesivir, umifenovir, among others) and blocking of immune system for cytokine storm control (IL-1 and IL-6 inhibitors, glucocorticoids, convalescent plasma, among others). CONCLUSIONS: Understanding of action mechanisms of SARS-CoV-2 enables us to direct efforts on effective therapeutic targets. This comprehensive review helps to interpret the clinical results of the several trials ongoing.

RESUMO

BACKGROUND: Inappropriate antibiotic prescribing practices predispose to resistance emergence. Despite the inclusion of the topic in medical school curricula worldwide, it is uncertain whether newly graduated medical interns have confidence in proper antibiotic prescription. OBJECTIVES: This study aimed to explore the antibiotic prescribing behaviours of the medical interns in Hong Kong and their barriers to appropriate antibiotic prescription. METHODS: Two focus groups were conducted among medical interns with training experiences in different public hospitals. Their prescribing behaviours and barriers were further examined with a questionnaire survey just before completion of internship. RESULTS: Focus group interviews identified a variety of hospital workplace cultures, including inappropriate empirical prescriptions and dosages, interns' passive roles in prescribing antibiotics and varied guidelines between different departments. Defensive medicine and lack of clinical experience were other barriers encountered. The interns believed that the incorrect practice learnt would perpetuate in their minds and affect their future practice. The top barriers reported by the survey respondents were adaptation to prescription culture of different hospitals (93.5%), lack of experience in antibiotic prescription (88.3%), inadequate knowledge in the choice of antibiotics (85.7%) and compliance with the seniors' instructions (80.6%). However, some focus group participants perceived weaker barriers in paediatric departments which provided close monitoring of antibiotic use. CONCLUSIONS: Inadequate knowledge and low confidence in antibiotic prescription led to the passive role of medical interns in antibiotic prescription, predisposing to future inappropriate practice. Inconsistent guidelines and prescription cultures between different hospitals and departments might further exacerbate their barriers.

RESUMO

Ultrasound guidance has been reported to facilitate the performance of lumbar punctures (LPs). However, the use of ultrasound guidance has not yet received consistent conclusions. We performed a systematic review and meta-analysis to determine the efficacy of ultrasound-guided LPs. PubMed, Embase and the Cochrane Library were searched for randomised controlled trials comparing ultrasound guidance with traditional palpation for LPs in adults. The primary outcome was risk of failed procedures. A random-effects Mantel-Haenzsel model or random-effects inverse variance model was used to calculate relative risks (RRs) or standardised mean differences (SMDs) with 95% CIs. Twenty-eight trials (N=2813) met the inclusion criteria. Ultrasound-guided LPs were associated with a reduced risk of failed procedures (RR=0.58, 95% CI 0.39 to 0.85, p=0.005). No significant heterogeneity was detected (I2=27%) among these trials. It further decreased first attempt to failure (RR=0.43, 95% CI 0.30 to 0.62, p<0.00001), mean attempts to success (SMD=-0.61, 95% CI -0.80 to -0.43, p=0.00001) and incidences of complications of headache and backache (RR=0.63, 95% CI 0.46 to 0.85, p=0.003). Ultrasound guidance is an effective technique for LPs in adults.

RESUMO

BACKGROUND: Medical education has observed numerous reforms in the last hundred years. While most of the reforms are applied to the undergraduate teaching, postgraduate education and training have lagged behind in keeping the pace. Anesthesiology curriculum has witnessed a few new methods inducted into practice like problem-based learning, flipped classroom etc. We introduced vertical integration with anatomy at our department and assessed its impact. METHODS: After a five-week schedule of integrated anatomy classes, a self-structured questionnaire was circulated amongst the 41 anesthesiology residents to know their perceptions and attitudes towards the classes. Their suggestions were also sought. The responses were analyzed with descriptive statistics (percentages). RESULTS: Thirty-six responses were received leading to a response rate of 87.8%. Fourteen residents (38.9%) believed that the integrated classes would be very helpful in their clinical practice, 20 (55.5%) residents believed them to be helpful while two (5.5%) residents believed that the classes would be little helpful in clinical practice. Hundred percent of the residents recommended the classes to be continued for the future batches. Half of the residents wanted the classes to be conducted twice in the three-year tenure (in the first and last semester) while 11 (30.5%) residents wanted the classes to be conducted every year. Seven (19.4%) residents thought that it's enough to conduct the classes once during the three-year tenure. Resident's suggested that they would like to have integrated classes with other departments like physiology, radiology, emergency medicine etc. CONCLUSION: The integrated classes with anatomy were well perceived by the anesthesiology residents. Vertically integrated curriculum should be introduced in postgraduate training of various specialties for better education and hence, better patient care.

RESUMO

Coronavirus has emerged as a global health threat due to its accelerated geographic spread over the last two decades. This article reviews the current state of knowledge concerning the origin, transmission, diagnosis and management of coronavirus disease 2019 (COVID-19). Historically, it has caused two pandemics: severe acute respiratory syndrome and Middle East respiratory syndrome followed by the present COVID-19 that emerged from China. The virus is believed to be acquired from zoonotic source and spreads through direct and contact transmission. The symptomatic phase manifests with fever, cough and myalgia to severe respiratory failure. The diagnosis is confirmed using reverse transcriptase PCR. Management of COVID-19 is mainly by supportive therapy along with mechanical ventilation in severe cases. Preventive strategies form the major role in reducing the public spread of virus along with successful disease isolation and community containment. Development of a vaccine to eliminate the virus from the host still remains an ongoing challenge.

RESUMO

Basic science educators are not trained as clinicians, yet are expected to adjust their content to mesh appropriately with its clinical application. While achievable, this is a challenge that requires intentional effort on the part of the basic science educators. A practical solution to facilitate curricular integration is to create experiential opportunities for basic scientists to observe the clinical application of their content and to pair these initiatives with training in effective medical education practices.
