RESUMO
Background: Computerized adaptive testing tailors test items to students' abilities by adapting difficulty level. This more efficient, and reliable assessment form may provide advantages over a conventional medical progress test (PT). Prior to our study, a direct comparison of students' performance on a computer adaptive progress test (CA-PT) and a conventional PT, which is crucial for nationwide implementation of the CA-PT, was missing. Therefore, we assessed the correlation between CA-PT and conventional PT test performance and explored the feasibility and student experiences of CA-PT in a large medical cohort. Methods: In this cross-over study medical students (n = 1432) of three Dutch medical schools participated in both a conventional PT and CA-PT. They were stratified to start with either a conventional PT or CA-PT to determine test performance. Student motivation, engagement and experiences were assessed by questionnaires in students from seven Dutch medical schools. Parallel-forms reliability was assessed using the Pearson correlation coefficient. Results: A strong correlation was found (0.834) between conventional PT and CA-PT test performance. The CA-PT was administered without system performance issues and was completed in a median time of 83 minutes (67-102 minutes). Questionnaire response rate was 31.7% (526/1658). Despite a higher experienced difficulty, most students reported persistence, adequate task management and good focus during the CA-PT. Conclusions: CA-PT provides a reliable estimation of students' ability level in less time than a conventional non-adaptive PT and is feasible in students throughout the entire medical curriculum. Despite the strong correlation between PT scores, students found the CA-PT more challenging.

AIMS: Despite clear guideline recommendations for initiating four drug classes in all patients with heart failure (HF) with reduced ejection fraction (HFrEF) and the availability of rapid titration schemes, information on real-world implementation lags behind. Closely following the 2021 ESC HF guidelines and 2023 focused update, the TITRATE-HF study started to prospectively investigate the use, sequencing, and titration of guideline-directed medical therapy (GDMT) in HF patients, including the identification of implementation barriers. METHODS AND RESULTS: TITRATE-HF is an ongoing long-term HF registry conducted in the Netherlands. Overall, 4288 patients from 48 hospitals were included. Among these patients, 1732 presented with de novo, 2240 with chronic, and 316 with worsening HF. The median age was 71 years (interquartile range [IQR] 63-78), 29% were female, and median ejection fraction was 35% (IQR 25-40). In total, 44% of chronic and worsening HFrEF patients were prescribed quadruple therapy. However, only 1% of HFrEF patients achieved target dose for all drug classes. In addition, quadruple therapy was more often prescribed to patients treated in a dedicated HF outpatient clinic as compared to a general cardiology outpatient clinic. In each GDMT drug class, 19% to 36% of non-use in HFrEF patients was related to side-effects, intolerances, or contraindications. In the de novo HF cohort, 49% of patients already used one or more GDMT drug classes for other indications than HF. CONCLUSION: This first analysis of the TITRATE-HF study reports relatively high use of GDMT in a contemporary HF cohort, while still showing room for improvement regarding quadruple therapy. Importantly, the use and dose of GDMT were suboptimal, with the reasons often remaining unclear. This underscores the urgency for further optimization of GDMT and implementation strategies within HF management.

AIMS: Current heart failure (HF) guidelines recommend to prescribe four drug classes in patients with HF with reduced ejection fraction (HFrEF). A clear challenge exists to adequately implement guideline-directed medical therapy (GDMT) regarding the sequencing of drugs and timely reaching target dose. It is largely unknown how the paradigm shift from a serial and sequential approach for drug therapy to early parallel application of the four drug classes will be executed in daily clinical practice, as well as the reason clinicians may not adhere to new guidelines. We present the design and rationale for the real-world TITRATE-HF study, which aims to assess sequencing strategies for GDMT initiation, dose titration patterns (order and speed), intolerance for GDMT, barriers for implementation, and long-term outcomes in patients with de novo, chronic, and worsening HF. METHODS AND RESULTS: A total of 4000 patients with HFrEF, HF with mildly reduced ejection fraction, and HF with improved ejection fraction will be enrolled in >40 Dutch centres with a follow-up of at least 3 years. Data collection will include demographics, physical examination and vital parameters, electrocardiogram, laboratory measurements, echocardiogram, medication, and quality of life. Detailed information on titration steps will be collected for the four GDMT drug classes. Information will include date, primary reason for change, and potential intolerances. The primary clinical endpoints are HF-related hospitalizations, HF-related urgent visits with a need for intravenous diuretics, all-cause mortality, and cardiovascular mortality. CONCLUSIONS: TITRATE-HF is a real-world multicentre longitudinal registry that will provide unique information on contemporary GDMT implementation, sequencing strategies (order and speed), and prognosis in de novo, worsening, and chronic HF patients.

BACKGROUND: Cardiac rehabilitation in patients with chronic heart failure (CHF) has favourable effects on exercise capacity, the risk at hospital (re-)admission and quality of life. Although cardiac rehabilitation is generally recommended it is still under-utilised in daily clinical practice, particularly in frail elderly patients after hospital admission, mainly due to low referral and patient-related barriers. Cardiac telerehabilitation (CTR) has the potential to partially solve these barriers. The purpose of this study is to evaluate the effects of CTR as compared to standard remote care after hospital admission on physical functional capacity in CHF patients. METHODS: In this randomised controlled trial, 64 CHF patients will be recruited during hospitalisation for acute decompensated heart failure, and randomised to CTR combined with remote patient management (RPM) or RPM alone (1:1). All participants will start with RPM after hospital discharge for early detection of deterioration, and will be up titrated to optimal medical therapy before being randomised. CTR will start after randomisation and consists of an 18-week multidisciplinary programme with exercise training by physical and occupational therapists, supported by a (remote) technology-assisted dietary intervention and mental health guiding by a physiologist. The training programme consists of three centre-based and two home-based video exercise training sessions followed by weekly video coaching. The mental health and dietary programme are executed using individual and group video sessions. A wrist-worn device enables remote coaching by the physical therapist. The web application is used for promoting self-management by the following modules: 1) goal setting, 2) progress tracking, 3) education, and 4) video and chat communication. The primary outcome measure is physical functional capacity evaluated by the Short Physical Performance Battery (SPPB) score. Secondary outcome measures include frailty scoring, recovery after submaximal exercise, subjective health status, compliance and acceptance to the rehabilitation programme, and readmission rate. DISCUSSION: The Tele-ADHF trial is the first prospective randomised controlled trial designed for evaluating the effects of a comprehensive combined RPM and CTR programme in recently hospitalised CHF patients. We hypothesize that this intervention has superior effects on physical functional capacity than RPM alone. TRIAL REGISTRATION: Netherlands Trial Registry (NTR) NL9619, registered 21 July 2021.

Background: Physicians may receive diagnostic information in different orders, and there is a lack of empirical evidence that the order of presentation may influence clinical reasoning. Objective: We investigated whether diagnostic accuracy of chest pain cases is influenced by the order of presentation of the history and electrocardiogram (EKG) to cardiology residents. Methods: We conducted an experimental study during a resident training in 2019. Twelve clinical cases were presented in 2 diagnostic rounds. Residents were randomly allocated to seeing the EKG first (EKGF) or the history first (HF). The mean diagnostic accuracy scores (range 0-1) and confidence level (0-100) in each diagnostic round and time needed to make the diagnosis were evaluated. Results: The final diagnostic accuracy was higher than the initial in both groups. After the first round, diagnostic accuracy was higher in HF (n=24) than in EKGF (n=28). Time taken to judge the history was comparable in both groups. Time taken to judge the EKG was shorter in HF (40±11 vs 64±13 seconds; P<.01). Time invested in the second round was significantly correlated with changing the initial diagnosis. A significant difference was observed in confidence ratings after the initial diagnosis, with EKGF reporting less confidence relative to HF. Conclusions: The order in which history and EKG are presented influences the clinical reasoning process.

Heart failure (HF) is a major health concern, which accounts for 1-2% of all hospital admissions. Nevertheless, there remains a knowledge gap concerning which interventions contribute to effective prevention of HF (re)hospitalization. Therefore, this umbrella review aims to systematically review meta-analyses that examined the effectiveness of interventions in reducing HF-related (re)hospitalization in HFrEF patients. An electronic literature search was performed in PubMed, Web of Science, PsycInfo, Cochrane Reviews, CINAHL, and Medline to identify eligible studies published in the English language in the past 10 years. Primarily, to synthesize the meta-analyzed data, a best-evidence synthesis was used in which meta-analyses were classified based on level of validity. Secondarily, all unique RCTS were extracted from the meta-analyses and examined. A total of 44 meta-analyses were included which encompassed 186 unique RCTs. Strong or moderate evidence suggested that catheter ablation, cardiac resynchronization therapy, cardiac rehabilitation, telemonitoring, and RAAS inhibitors could reduce (re)hospitalization. Additionally, limited evidence suggested that multidisciplinary clinic or self-management promotion programs, beta-blockers, statins, and mitral valve therapy could reduce HF hospitalization. No, or conflicting evidence was found for the effects of cell therapy or anticoagulation. This umbrella review highlights different levels of evidence regarding the effectiveness of several interventions in reducing HF-related (re)hospitalization in HFrEF patients. It could guide future guideline development in optimizing care pathways for heart failure patients.

Many medical skills are complex due to their requirements for integration of declarative (biomedical) knowledge with perceptual-motor and perceptual-cognitive proficiency. While feedback generally helps learners guide their actions, it is unclear how feedback supports the integration of declarative knowledge with skills. Thus, we investigated the effect of expert and augmented feedback on acquisition and retention of a complex medical skill (acquiring a transthoracic echocardiogram) in a simulation study. We randomly assigned 36 medical undergraduate students to one of three feedback sources: Expert (EF), Augmented visual (HS), and Expert plus Help Screen (EF + HS). Participants practiced until reaching proficiency. Outcome measures (knowledge test and practical skill ratings on a 5-point scale), were gathered at initial acquisition and at retention after 11 days, the time needed to obtain the images and the quality of images obtained. We divided the knowledge test into three topics: names of the images, manipulation of the probe, and anatomy of the heart. At acquisition, immediately after training, EF group participants were faster at obtaining images than participants in the two other groups. On the retention test, there were no group differences for speed of obtaining images, but the EF + HS group scored significantly higher than the other two groups on image quality. Thus, expert feedback best assisted initial acquisition and combined augmented and expert feedback best assisted retention of this complex medical task. Expert assistance reduced learners' cognitive load during initial practice, helping learners integrate declarative knowledge with physical skills.

Teaching and learning practices often fail to incorporate new concepts in the ever-evolving field of medical education. Although medical education research provides new insights into curricular development, learners' engagement, assessment methods, professional development, interprofessional education, and so forth, faculty members often struggle to modernize their teaching practices. Communities of practice (CoP) for faculty development offer an effective and sustainable approach for knowledge management and implementation of best practices. A successful CoP creates and shares knowledge in the context of a specific practice toward the development of expertise. CoPs' collaborative nature, based on the co-creation of practical solutions to daily problems, aligns well with the goals of applying best practices in health professions education and training new faculty members. In our article, we share 12 tips for implementing a community of practice for faculty development. The tips were based on a comprehensive literature review and the authors' experiences.

PURPOSE: Assessment in different languages should measure the same construct. However, item characteristics, such as item flaws and content, may favor one test-taker group over another. This is known as item bias. Although some studies have focused on item bias, little is known about item bias and its association with items characteristics. Therefore, this study investigated the association between item characteristics and bias. METHODS: The University of Groningen offers both an international and a national bachelor's program in medicine. Students in both programs take the same progress test, but the international progress test is literally translated into English from the Dutch version. Differential item functioning was calculated to analyze item bias in four subsequent progress tests. Items were also classified by their categories, number of alternatives, item flaw, item length, and whether it was a case-based question. RESULTS: The proportion of items with bias ranged from 34% to 36% for the various tests. The number of items and the size of their bias was very similar in both programmes. We have identified that the more complex items with more alternatives favored the national students, whereas shorter items and fewer alternatives favored the international students. CONCLUSION: Although nearly 35% of all items contain bias, the distribution and the size of the bias were similar for both groups. The findings of this paper may be used to improve the writing process of the items, by avoiding some characteristics that may benefit one group whilst being a disadvantage for others.

Myocardial Bridging (MB) refers to the band of myocardium that abnormally overlies a segment of a coronary artery. This paper quantitatively evaluates the influence of MB of the left anterior descending artery (LAD) on myocardial perfusion of the entire left ventricle. We studied 131 consecutive patients who underwent hybrid rest/stress 13N-ammonia positron emission tomography (PET) and coronary computed tomography angiography (CCTA) due to suspected myocardial ischemia. Patients with previous myocardial infarction and/or significant coronary artery disease (≥ 50% stenosis) were excluded. Myocardial perfusion measurements were compared between patients with and without LAD-MB. Additionally, we evaluated the relationship between anatomical characteristics (length and depth) of LAD-MB and myocardial perfusion measurements. 17 (13%) patients presented a single LAD-MB. Global myocardial perfusion reserve (MPR) was lower in patients with LAD-MB than in patients without LAD-MB (1.9 ± 0.5 vs. 2.3 ± 0.6, p < 0.01). Global stress myocardial blood flow (MBF) was similar in patients with and without LAD-MB (2.2 ± 0.4 vs. 2.3 ± 0.7 ml/g/min, p = 0.40). Global rest MBF was higher in patients with LAD-MB than in patients without LAD-MB (1.2 ± 0.3 vs. 1.0 ± 0.2 ml/g/min, p < 0.01). Global rest MBF, stress MBF, and MPR quantifications were similar in patients with superficial and deep LAD-MB (all p = NS). We did not find any correlation between length and global rest MBF, stress MBF nor MPR (r = - 0.14, p = 0.59; r = 0.44, p = 0.07; and r = 0.45, p = 0.07 respectively). Quantitative myocardial perfusion suggests that LAD-MB may be related to impaired perfusion reserve, an indicator of microvascular dysfunction. Anatomical characteristics of LAD-MB were not related to changes in myocardial perfusion.

Introduction: Teaching medical skills during clinical rotation is a complex challenge, which often does not allow students to practise their skills. Nowadays, the use of simulation training has increased to teach skills to medical students. However, transferring the learnt skills from one setting to the other is challenging. In this study, we investigated whether adding a simulation training before the clinical rotation would improve students' acquisition and retention of knowledge. Methods: Two subsequent cohorts were compared. Group A followed the traditional curriculum without additional simulation training. Group B attended an additional simulation training, in which history taking, physical examination and procedures for the primary survey in emergency situations were taught. Both groups answered the same knowledge test before entering their clinical rotation and after 6 months. To analyse students' scores over time, we conducted a repeated measure analysis of variance. To investigate the difference between knowledge, we conducted a t-test. Results: Group B scored significantly higher in both tests and all subscores, except in the Trauma topic in the first measurement point. Students in group A showed decay in knowledge whereas group B showed an increase in knowledge. Conclusions: Adding a simulation training, before students entered their clinical rotation, improves students' knowledge acquisition and retention compared with those who did not receive the additional simulation training.
RESUMO
AIMS: Cumulative assessment has been used as a tool to steer students' study behavior, since it increases students' self-study time while spreading their study time more evenly throughout the span of the course. However, little is known about the impact of cumulative assessment on students' knowledge growth. Therefore, our study compared the growth of knowledge of students who attended a course with cumulative assessment with those with end-of-course assessment. We hypothesized that students in the cumulative assessment condition would have a higher increase in knowledge compared to students in the end-of-course assessment condition. METHODS: This is a follow-up study of a previous randomized experiment that compared students' performance between students who attended a course with cumulative assessment with those with end-of-course assessment. We gathered data of the first four subsequent Dutch interuniversity progress test after the experiment from 62 students. Of those, 37 students were in the end-of-course assessment condition and 25 were in the cumulative assessment condition. The questions were classified as part of the teaching block or not. To analyze students' knowledge growth, we conducted a General Linear Model. RESULTS: Our results demonstrated that there was a significant increase in students' knowledge of the four subsequent progress tests. Additionally, our general linear model showed no difference between both groups, indicating that cumulative assessment and end-of-course assessment produced similar outcomes when comparing students' knowledge growth. CONCLUSIONS: So far, little evidence has supported the use of cumulative assessment as a tool for increasing students' knowledge growth. The lack of finding a positive effect of cumulative assessment on knowledge retention may be explained by the repetitive character of our (spiral) curriculum.
OBJETIVOS: A avaliação cumulativa tem sido usada como uma ferramenta para orientar o comportamento de estudo dos alunos, uma vez que aumenta o tempo de auto aprendizado, ao mesmo tempo que distribui o tempo de estudo de forma mais uniforme ao longo do curso. No entanto, pouco se sabe sobre o impacto da avaliação cumulativa na evolução do conhecimento dos estudantes. Portanto, nosso estudo comparou o aumento do conhecimento entre estudantes que participaram de um curso com avaliação cumulativa, e aqueles que tiveram avaliação de fim de curso. Nossa hipótese é que os estudantes na condição de avaliação cumulativa teriam um aumento maior no conhecimento em comparação com os estudantes na condição de avaliação do final do curso. MÉTODOS: Este é um estudo de acompanhamento de um experimento randomizado anterior, que comparou o desempenho entre estudantes que participaram de um curso com avaliação cumulativa e aqueles com avaliação de fim de curso. Nós reunimos dados dos primeiros quatro Testes do Progresso interuniversitários holandeses subsequentes ao experimento, em 62 estudantes. Destes, 37 estavam na condição de avaliação de final de curso e 25 estavam na condição de avaliação cumulativa. As questões foram classificadas como parte do bloco de ensino ou não. Para analisar o crescimento do conhecimento dos estudantes, conduzimos um Modelo Linear Geral. RESULTADOS: Nossos resultados demonstraram que houve um aumento significativo no conhecimento dos estudantes nos quatro Testes do Progresso subsequentes. Além disso, nosso modelo linear geral não mostrou diferença entre os dois grupos, indicando que a avaliação cumulativa e a avaliação no final do curso produziram resultados semelhantes ao comparar o crescimento do conhecimento dos alunos. CONCLUSÕES: Até agora, pouca evidência apoiou o uso da avaliação cumulativa como uma ferramenta para aumentar o crescimento do conhecimento dos alunos. A falha em encontrar um efeito positivo da avaliação cumulativa na retenção de conhecimento pode ser explicada pelo caráter repetitivo do nosso currículo (em espiral).

Aims: To evaluate the prognostic value of quantitative myocardial perfusion imaging with positron emission tomography (PET) for adverse cardiovascular outcomes in patients with known or suspected coronary artery disease (CAD). Methods and results: A search in MEDLINE and Embase was conducted for studies that evaluated (i) myocardial perfusion in absolute terms with PET, (ii) prognostic value for the development of major adverse cardiovascular events (MACE), cardiac death, and/or all-cause mortality, and (iii) patients with known or suspected CAD. Studies were divided according to the radiotracer utilized and their included population (patients with and without previous infarction). Comprehensive description and a selected instance of pooling were performed. Eight studies (n = 6804) were analysed and documented clear variability in population, quantitative PET variables operationalization [stress myocardial blood flow (sMBF) and flow reserve (MFR)], statistical covariate structure, follow-up, and radiotracer utilized. MFR was independently associated with MACE in eight studies [range of adjusted hazard ratios (HRs): 1.19-2.93]. The pooling instance demonstrated that MFR significantly associates with the development of MACEs (HR: 1.92 [1.29, 2.84]; P = 0.001). sMBF was only associated with MACE in two studies that evaluated it, and only one study documented sMBF as a better predictor than MFR. Conclusion: This systematic review demonstrates the prognostic value of quantitative myocardial perfusion evaluated with PET, in the form of MFR and sMBF, for the development of major adverse cardiovascular outcomes in populations with known or suspected CAD. In the qualitative comparison, MFR seems to outperform sMBF as an independent prognostic factor. Evidence is still lacking for assessing quantitative PET for the occurrence of cardiac death and all-cause mortality. There is clear heterogeneity in predictor operationalization and study performances.

AIMS: In this article, we want to share our perspective on how simulation sessions could contribute to change reality, building a safe environment in which facilitators can role-modeling students to develop emotional competence. Noteworthy, acknowledging and legitimating emotions are also essential components of creating a safe environment for students. We also intend to stress how faculty development programs are essential to guarantee that facilitators will be prepared to accomplish this new learning goal, and how different cultural contexts can influence the process. METHODS: In this narrative review, we will focus on the importance of emotions. Emotions in the context of learning but also learners' emotions from the viewpoint of teachers, and teachers' emotions in the context of faculty development. RESULTS: Simulation in medical education is becoming increasingly important. Advances in technology give many opportunities to simulate almost anything you want, with high fidelity and enhanced reality. It creates the possibility of bringing the complexity of real clinical tasks to a controlled simulated environment. While performing these complex simulated tasks, students experience several and sometimes distinct emotions: the emotions of patients and their families, the emotions of the multi-professional team members, and their own emotions, as learners and as future health professionals. Unfortunately, the formal curricula of the majority of medical schools do not address the importance of emotional competence specifically, and students end with the general impression that emotions are mainly negative, and must be avoided and kept at a safe distance. However, there are plenty of data showing how emotions can influence learning and decision-making, and how important it is to create awareness of and modulate them to guarantee the safeguard of patients' interests. CONCLUSIONS: Emotions directly affect several dimensions of clinical work, such as communication, decision-making, teamwork, and leadership. We hope that including dealing with emotions as a natural goal of the learning activities in the health professions can catalyze the reconciliation between the technical and emotional aspects of clinical practice.
OBJETIVOS: Neste artigo, pretendemos compartilhar nossa perspectiva em relação a como a simulação pode ajudar a transformar a realidade, construindo um ambiente seguro em que os facilitadores das sessões de simulação sejam os modelos em que os estudantes podem se espelhar para desenvolver competência emocional. Vale ressaltar que reconhecer e dar legitimidade às emoções é passo essencial para a criação de um ambiente seguro para os estudantes. Também pretendemos reforçar como os programas de capacitação docente são fundamentais para garantir que os facilitadores estarão preparados para atingir esse novo objetivo de aprendizagem, e como contextos culturais diferentes podem influenciar esse processo. MÉTODOS: Nesta revisão narrativa, nos concentraremos na importância das emoções. Emoções no contexto da aprendizagem, mas também emoções dos aprendizes do ponto de vista dos professores, e emoções dos professores no contexto do desenvolvimento do corpo docente. RESULTADOS: A simulação está se tornando cada vez mais importante na educação médica. Os avanços tecnológicos permitem simular praticamente qualquer situação, com alta fidelidade e realidade. Isso cria a possibilidade de trazer a complexidade de situações clínicas reais para um ambiente simulado e controlado. Ao executar essas simulações de alta complexidade, os estudantes experimentam várias e diferentes emoções: as emoções dos pacientes e de suas famílias, as emoções dos membros da equipe, e as suas próprias emoções, como estudantes e como futuros profissionais da saúde. Infelizmente, a grade curricular formal da maioria das escolas médicas não aborda especificamente a importância de desenvolver competência emocional, e os estudantes acabam com a impressão geral de que as emoções são basicamente negativas, e que devem ser evitadas e mantidas a uma distância de segurança. No entanto, vários estudos mostram como as emoções influenciam o aprendizado e a tomada de decisões, e como é importante estar consciente delas e modulá-las de uma forma que garanta a salvaguarda dos interesses dos pacientes. CONCLUSÕES: As emoções afetam diretamente várias dimensões do trabalho clínico, como comunicação, tomada de decisão, trabalho em equipe e liderança. Esperamos que tratar das emoções como meta natural das atividades de aprendizagem nas profissões da saúde oportunize catalisar a reconciliação entre os aspectos técnicos e emocionais da prática clínica.

Over the past 5 years, cancer has replaced coronary heart disease as the leading cause of death in the Netherlands. It is thus paramount that medical doctors acquire a knowledge of cancer, since most of them will face many patients with cancer. Studies, however, have indicated that there is a deficit in knowledge of oncology among medical students, which may be due not only to the content but also to the structure of the curriculum. In this study, we compared students' knowledge acquisition in four different undergraduate medical programs. Further, we investigated possible factors that might influence students' knowledge growth as related to oncology. The participants comprised 1440 medical students distributed over four universities in the Netherlands. To measure students' knowledge of oncology, we used their progress test results from 2007 to 2013. The progress test consists of 200 multiple-choice questions; this test is taken simultaneously four times a year by all students. All questions regarding oncology were selected. We first compared the growth of knowledge of oncology using mixed models. Then, we interviewed the oncology coordinator of each university to arrive at a better insight of each curriculum. Two schools showed similar patterns of knowledge growth, with a slight decrease in the growth rate for one of them in year 6. The third school had a faster initial growth with a faster decrease over time compared to other medical schools. The fourth school showed a steep decrease in knowledge growth during years 5 and 6. The interviews showed that the two higher-scoring schools had a more focused semester on oncology, whereas in the others, oncology was scattered throughout the curriculum. Furthermore, the absence of a pre-internship training program seemed to hinder knowledge growth in one school. Our findings suggest that curricula have an influence on students' knowledge acquisition. A focused semester on oncology and a pre-internship preparatory training program are likely to have a positive impact on students' progress in terms of knowledge of oncology.

Starting in 2009, cancer has been the leading cause of death in the Netherlands. Oncology is therefore an important part of the medical curriculum in undergraduate education. It is crucial that medical students know about cancer, since doctors will encounter many cases of oncology. We have compared the influence that teaching oncology has when spread over a 3-year curriculum versus concentrated in one semester. The participants comprised 525 medical students from one medical school with comprehensive integrated curricula. Of those, 436 followed the massed curriculum, with oncology concentrated in one semester. The remaining 89 students followed a spaced-out curriculum, in which oncology was spread out over 3 years. To measure students' knowledge, we used their progress test results from 2009 to 2012. All questions about oncology were categorized and selected. Because of our unbalanced sample and missing data and to reduce the chances for a type II error, we compared the growth of oncology questions using mixed effect models. A cubic growth model with an unstructured covariance matrix fitted our data best. At the start, students in the spaced-out curriculum scored higher on oncology questions. The initial growth was faster for the spaced-out curriculum students, whereas the acceleration over time was slower compared to the massed curriculum students. At the end of the growth curve, the knowledge of the massed curriculum students increased faster. In the last test, the massed curriculum students outperformed those in the spaced-out curriculum. The way students acquired and applied their knowledge was similar in both curricula. It seems, however, that students benefitted more from massed than spaced-out education, which may be due to the comprehensive integrated teaching involved.

BACKGROUND: Cardiac PET quantifies stress myocardial blood flow (MBF) and perfusion reserve (MPR), while ECG-gated datasets can measure components of ventricular function simultaneously. Stress MBF seems to outperform MPR in the detection of significant CAD. However, it is uncertain which perfusion measurement is more related to ventricular function. We hypothesized that stress MBF correlates with ventricular function better than MPR in patients studied for suspected myocardial ischemia. METHODS: We studied 248 patients referred to a rest and adenosine-stress Nitrogen-13 ammonia PET. We performed a multivariate analysis using systolic function (left ventricular ejection fraction, LVEF), diastolic function (mean filling rate in diastole, MFR/3), and synchrony (Entropy) as the outcome variables, and stress MBF, MPR, and relevant covariates as the predictors. Secondarily, we repeated the analysis for the subgroup of patients with and without a previous myocardial infarction (MI). RESULTS: 166 male and 82 female patients (mean age 63 ± 11 and 67 ± 11 year, respectively) were included. 60% of the patients presented hypertension, 57% dyslipidemia, 21% type 2 diabetes mellitus, 45% smoking, and 34.7% a previous MI. Mean stress MBF was 1.99 ± 0.75 mL/g/min, MPR = 2.55 ± 0.89, LVEF = 61.6 ± 15%, MFR/3 = 1.12 ± 0.38 EDV/s, and Entropy = 45.6 ± 11.3%. There was a significant correlation between stress MBF (P < .001) and ventricular function. This was stronger than the one for MPR (P = .063). Sex, age, diabetes, and extent of previous MI were also significant predictors. Results were similar for the analyses of the 2 subgroups. CONCLUSION: Stress MBF is better correlated with ventricular function than MPR, as evaluated by Nitrogen-13 ammonia PET, independently from other relevant cardiovascular risk factors and clinical covariates. This relationship between coronary vasodilatory capacity and ventricular function is sustained across groups with and without a previous MI.

BACKGROUND: Patients with ischemic cardiomyopathy (ICM) are at risk for ventricular arrhythmias and are protected by an implantable cardioverter defibrillator (ICD). Visualization of cardiac sympathetic innervation may play an additional role to left ventricular ejection fraction (LVEF) in identifying those patients who will benefit from ICD therapy. The purpose of this study was to detect the role of sympathetic denervation in the genesis of ventricular arrhythmias in ICM patients. METHODS: Twenty patients with ICM and LVEF <30% were included in this pilot study. Included patients were equally stratified into two groups: no history of arrhythmias (group A) and recurrent arrhythmias (group B). All patients underwent cardiac sympathetic denervation (using carbon-11 labelled meta-hydroxy-ephedrine ([11C]-mHED)), myocardial ischemia and viability detection. Patients were followed up to one year after the imaging studies. RESULTS: Mean age was 63±7.5 years. Mean global retention of [11C]-mHED was 0.055±0,012 min-1, and was not different between the two patient groups: 0.056±0.011 min-1 vs. 0.054±0.013 min-1 for group A vs. group B, respectively. During follow-up, seven patients developed ventricular arrhythmias, and four patients died. No difference in [11C]-mHED retention was found between patients with and without ventricular arrhythmia during follow-up. However, size of denervated area was larger in patients who died during follow-up: 10±1 segments vs. 6±2 segments, P=0.002. CONCLUSIONS: Cardiac sympathetic innervation is impaired in patients with ischemic cardiomyopathy. All-cause mortality occurred in those patients with large areas of [11C]-mHED defect.

OBJECTIVE: Spreading training sessions over time instead of training in just 1 session leads to an improvement of long-term retention for factual knowledge. However, it is not clear whether this would also apply to surgical skills. Thus, we performed a systematic review to find out whether spacing training sessions would also improve long-term retention of surgical skills. DESIGN: We searched the Medline, PsycINFO, Embase, Eric, and Web of Science online databases. We only included articles that were randomized trials with a sample of medical trainees acquiring surgical motor skills in which the spacing effect was reported. The quality and bias of the articles were assessed using the Cochrane Collaboration's risk of bias assessment tool. RESULTS: With respect to the spacing effect, 1955 articles were retrieved. After removing duplicates and articles that did not meet the inclusion criteria, 11 articles remained. The overall quality of the experiments was "moderate." Trainees in the spaced condition scored higher in a retention test than students in the massed condition. CONCLUSIONS: Our systematic review showed evidence that spacing training sessions improves long-term surgical skills retention when compared to massed practice. However, the optimal gap between the re-study sessions is unclear.

BACKGROUND: Progress testing is an assessment tool used to periodically assess all students at the end-of-curriculum level. Because students cannot know everything, it is important that they recognize their lack of knowledge. For that reason, the formula-scoring method has usually been used. However, where partial knowledge needs to be taken into account, the number-right scoring method is used. Research comparing both methods has yielded conflicting results. As far as we know, in all these studies, Classical Test Theory or Generalizability Theory was used to analyze the data. In contrast to these studies, we will explore the use of the Rasch model to compare both methods. METHODS: A 2 × 2 crossover design was used in a study where 298 students from four medical schools participated. A sample of 200 previously used questions from the progress tests was selected. The data were analyzed using the Rasch model, which provides fit parameters, reliability coefficients, and response option analysis. RESULTS: The fit parameters were in the optimal interval ranging from 0.50 to 1.50, and the means were around 1.00. The person and item reliability coefficients were higher in the number-right condition than in the formula-scoring condition. The response option analysis showed that the majority of dysfunctional items emerged in the formula-scoring condition. CONCLUSIONS: The findings of this study support the use of number-right scoring over formula scoring. Rasch model analyses showed that tests with number-right scoring have better psychometric properties than formula scoring. However, choosing the appropriate scoring method should depend not only on psychometric properties but also on self-directed test-taking strategies and metacognitive skills.
