RESUMO
Uncertainty is a fundamental aspect of medical practice, necessitating incorporation into undergraduate medical training. The integrative model of uncertainty tolerance (UT) developed by Hillen and Han serves as a comprehensive framework for exploring clinical uncertainty. While studies have extensively examined UT dimensions, including sources, responses, and moderators, the factors influencing the perception of uncertainty stimuli remain underexplored. However, students' ability to perceive uncertainty and their approach to uncertain stimuli play a crucial role in enabling them to develop adaptive responses to uncertainty, necessary for their comfort in these situations. Defining uncertainty as a metacognitive state suggests significant variability in its perception among individuals and within an individual over time. Moreover, several studies have demonstrated the substantial influence of various individual and contextual factors on how individuals perceive and respond to uncertainty. In this paper, the authors present multiple hypotheses to address the question of whether students genuinely perceive uncertainty stimuli when they should. The authors argue that students' personal relationship with their knowledge is essential in their ability to identify clinical uncertainty, particularly concerning the limits of medical knowledge. Therefore, they propose that an academic culture fostering doubt, through exposing students to a variety of perspectives, would enhance their ability to identify uncertainty zones in a clinical situation at an early stage. Drawing on Dewey's situational theory, the authors emphasize the importance of better understanding, in a work setting, the influence of contextual and situational characteristics on individual perceptions of uncertainty. In line with this idea, ethnographic studies would offer valuable insights into identifying the relationship between the students, their work environment, and their perception of clinical uncertainty.
RESUMO
BACKGROUND: The goal of this study was to examine the impact of subjective and physiological stress responses on medical students' diagnostic reasoning and communication skills. METHOD: A prospective randomized quantitative study was undertaken, looking at ambulatory consultations in internal medicine. On the first day (baseline day), volunteer year 6 students (n = 41) participated in a simulated ambulatory consultation with standardized patients (SPs). On the second day (study day), one week later, they were randomly assigned to two groups: a low stress (n = 20) and a high stress (n = 21) simulated ambulatory consultation. Stress was measured using validated questionnaires and salivary cortisol. The SPs assessed the students' reasoning and communication. The students completed assessments of their clinical reasoning after the consultations. RESULTS: Although stress measures were all significantly higher in the high-stress condition (all p < 0.05), no differences were found in diagnostic accuracy and justification scores. However, correlational analyses revealed a negative correlation between multiple-stress measures and the students' ability to generate arguments for differential diagnoses. CONCLUSION: Stress was associated with impairments in clinical reasoning, of a nature typically suggestive of premature closure.

Uncertainty in inherent to every aspects of medical practice. As the concept of uncertainty in healthcare is still to explore, deciphering the determinants and the roots of this uncertainty would benefit from the insights of various disciplines, such as epistemology, sociology, mathematics, or philosophy. The urgent need to improve physician's ability to cope with uncertainty, has been recently highlighted by the COVID-19 pandemic. Besides, the concept of uncertainty tolerance has been proposed, and could serve as a relevant basis for approaching uncertainty, in medical education. Thus, we propose at first to discuss the uncertainty tolerance framework from Hillen et al. Then, from an educational perspective, we outline some avenues regarding how uncertainty tolerance could be thought, in a competence-based approach, and discuss several educational activities, which have proven efficient in promoting uncertainty tolerance among medical practitioners abroad.

INTRODUCTION: In France, at the end of the sixth year of medical studies, students take a national ranking examination including progressive clinical case-based multiple-choice questions (MCQs). We aimed to evaluate the ability of these MCQs for testing higher-order thinking more than knowledge recall, and to identify their characteristics associated with success and discrimination. METHODS: We analysed the 72 progressive clinical cases taken by the students in the years 2016-2019, through an online platform. RESULTS: A total of 72 progressive clinical cases (18 for each of the 4 studied years), corresponding to 1059 questions, were analysed. Most of the clinical cases (n=43, 60%) had 15 questions. Clinical questions represented 89% of all questions, whereas basic sciences questions accounted for 9%. The most frequent medical subspecialties were internal medicine (n=90, 8%) and infectious diseases (n=88, 8%). The most frequent question types concerned therapeutics (26%), exams (19%), diagnosis (14%), and semiology (13%). Level 2 questions ("understand and apply") accounted for 59% of all questions according to the Bloom's taxonomy. The level of Bloom's taxonomy significantly changed over time with a decreasing number of level 1 questions ("remember") (P=0.04). We also analysed the results of the students among 853 questions of training ECNi. Success and discrimination significantly decreased when the number of correct answers increased (P<0.0001 both). The success, discrimination, mean score, and mean number of discrepancies did not differ according to the diagnosis, exam, imaging, semiology, or therapeutic type of questions. CONCLUSION: Progressive clinical case-based MCQs represent an innovative way to evaluate undergraduate students.

OBJECTIVES: Whereas administration of erythropoietin (EPO) acutely after myocardial infarction (MI) reduces infarct size and chronic EPO therapy attenuates post-MI remodeling, the safety of chronic EPO therapy following MI is unknown. Therefore, we examined the thrombogenic effects of a chronic EPO therapy after MI. METHODS: Rats underwent coronary occlusion followed by reperfusion. They were assigned to one of the following groups: EPO-A, single injection of EPO 5,000 U/kg at the time of reperfusion; EPO-C, injection of EPO 5,000 U/kg at the time of reperfusion followed by 300 U/kg/week; PBS-C, injection of vehicle only. After eight weeks of treatment they were exposed to a validated prethrombotic test based on partial stenosis of the inferior vena cava. RESULTS: As compared to the rats receiving vehicle only, the rats treated with EPO exhibited a significant reduction in MI size (28.7 +/- 2.1% and 25.8 +/- 1.9 vs. 39.8 +/- 3.0% in EPO-A, EPO-C and PBS-C, respectively; p < 0.05). Whereas the hematocrit was significantly increased in EPO-C (59.7 +/- 2.0% vs. 44.7 +/- 0.9% in EPO-A, p < 0.001), the proportion of rats in which a thrombus occurred was similar in all groups (p = 0.52). CONCLUSION: Chronic EPO therapy added to the single high dose of EPO injected acutely did not induce venous pro-thrombotic effect in rats.

Uncertainty arises when information is not sufficient to predict the prognosis or the outcome following an intervention. It is omnipresent in medical daily practice, and will follow each practitioner all along his career. The communication or merely even the feeling of uncertainty is frequently perceived as a negative experience. Nevertheless, rather than a sign of weakness, feeling uncertain reflects a dynamic state of self-reassessment which should be experienced by each doctor involved in providing his patients with the best care. Furthermore, uncertainty may lead to disastrous consequences for practitioners who have not been properly prepared to it, involving the sphere of emotions (stress, anxiety, burn-out) as well as the behavioral field (misdiagnosis, excessive testing, impaired communication ). A growing number of observations, clinical or educational studies, supports the idea that learning uncertainty should be a critical prerequisite to a valuable medical practice. Through this literature review, we propose herein a conceptual glance on uncertainty. Then, we expose some sources of uncertainty in daily practice and teaching, its consequences, and the main factors that contribute to the wide variety of the individual relationship with uncertainty. We finally aim to prompt a global reflexion, falling within an uncertainty competency-based education approach, assuming that our obligation to professionalize the students necessitates making them skilled in dealing with uncertainty.

Many factors can contribute to the risk of venous thrombosis observed in hemolytic diseases. Some mechanisms are related to hemolysis by itself, while others seem more specific to each disease. Despite recent advances in the quantification of this risk and in understanding its physiopathology, the association of hemolysis with venous thrombosis is often unknown. The purpose of this general review is to clarify the main pro-thrombotic mechanisms during hemolysis and to synthesize the clinical data currently available. We will focus on the main types of hemolytic pathologies encountered in current practice, namely paroxysmal nocturnal hemoglobinuria, hemoglobinopathies, auto-immune hemolytic anemia and thrombotic microangiopathies.

INTRODUCTION: Though several assessment tools for resident professional skills based on workplace direct observation have been validated, they remain scarcely used in France. The objective of this study was to evaluate the reliability and the validity of a workbook including several assessment forms for different components of the professional competency. METHODS: Three assessment forms have been tested over a period of 6 months in a multicentric study including 12 French internal medicine departments: the French version of the mini-CEX, an interpersonal skills assessment form (OD_CR) and the multisource feedback form (E_360). Reliability has been assess using the intra-class correlation coefficient (ICC) and the Cronbach alpha coefficient. Arguments for validity have been provided looking at the ability of the forms to detect an increase in the scores over time and according to the level of experience of the resident. RESULTS: Twenty-five residents have been included. The Cronbach alpha was of 0.90 (n=70) with the mini-CEX, 0.89 with the OD_CR (n=62) and 0.77 with the E_360 (n=86). ICC showed a wide variation according to the items of the mini-CEX and the OD-CR probably due to the poor number of observations performed by residents. The scores of most of the items of these two forms increased between M1 and M6. The scores of the E_360 were high: 7.3±0.8 to 8.3±2.4 (maximum 9) and did not vary according to the level of experience. CONCLUSION: This study suggest that it would be difficult to ensure a sufficient reliability for professional skills assessment using these tools given our available current human and material resources. However, these assessment forms could be added to the resident portfolio as supports for the debriefing in order to document their progression during their formation.

PURPOSE: Some acute medical illnesses are associated with an increased risk of venous thromboembolism. This risk is difficult to assess in medical patients on account of the multiplicity of their pathologies, leading to potential interactions between numerous risk factors. CURRENT KNOWLEDGE AND KEY POINTS: A rational analysis of the risk of venous thrombosis in acute medical setting may be derived from pathogenic models and be based on elementary risk factors for venous thromboembolism classified as transient, permanent, major and intermediate factors. The systematic study of pathophysiological mechanisms in process, in each medical patient could guide the physician attitude toward still non-evaluated situations. FUTURE PROSPECTS AND PROJECTS: A synthesis of the last epidemiological and pathophysiological data is developed in the first part of this literature review, whereas the risk linked to specific situations in ambulatory, hospital or internal medicine settings will be described in the second part.

PURPOSE: The increased risk of thromboembolism in acute medical illnesses (AMI) is difficult to assess because of the diversity of medical conditions. The first part of this review of the literature was dedicated to methods of risk analysis based on our current pathophysiological knowledge. This second part describes more specifically the risk of venous thrombosis linked to AMI in hospital, ambulatory and internal medicine settings. CURRENT KNOWLEDGE AND KEY POINTS: The incidence of venous thromboembolism is higher in hospital than in ambulatory setting, albeit the latter remains significant. Stroke and affections leading to intensive care management represent conditions at great risk. Several mechanisms leading to a prothrombotic state have been identified, explaining the increased risk observed during relapses of pathologies specifically treated in internal medicine such as lupus erythematosus, Wegener granulomatosis, inflammatory bowel diseases and Behcet's disease. FUTURE PROSPECTS AND PROJECTS: Next to the pathophysiological understanding of venous thrombosis, the assessment of the specific thrombogenic burden of an AMI is an additive tool to screen medical patients at high risk. This systematic review of the literature shows uncertainties towards some risk factors as bedrest or acute inflammatory response. Taking into account the methodological difficulties inherent to prospective and epidemiological studies, a meta-analysis focusing on these factors would be useful to refine prevention guidelines for venous thromboembolism in medical setting.

BACKGROUND: After stopping a 3 to 6 months course of oral anticoagulation for a first episode of idiopathic venous thromboembolism (VTE), the risk of recurrent VTE is high (10% per year). In this setting, international guidelines recommend at least 6 months treatment. However, this recommendation is not satisfactory for the following reasons: (1) no randomized trial has compared 6 months to extended duration (2 years) anticoagulation; and (2), even though the frequency of recurrent VTE is similar after pulmonary embolism (PE) and deep vein thrombosis (DVT), the fatality rate of recurrent VTE after PE is higher than that after DVT. METHODS: A French multicentre double blind randomized trial. The main objective is to demonstrate, after a first episode of symptomatic idiopathic PE treated for 6 months using a vitamin K antagonist, that extended anticoagulation for 18 months (INR between 2 and 3) is associated with an increased benefit / risk ratio (recurrent VTE and severe anticoagulant-related bleeding) compared to placebo. The double blind evaluation is ensured using by active warfarin and placebo, and blinded INR. The protocol was approved by the ethics board of the Brest Hospital on the 7th of March 2006. For an alpha risk of 5% and a beta risk of 20%, the estimated sample size is 374 patients. EXPECTED RESULTS: This study has the potential to: (1) demonstrate that the benefit / risk ratio of extended anticoagulation for 18 months is higher than that observed with placebo in patients with a first episode of idiopathic PE initially treated for 6 months, during and after the treatment period; and (2) to validate or invalidate the contribution of isotope lung scans, lower limb Doppler ultrasound and D-Dimer at 6 months of treatment as predictors of recurrent VTE (medico-economic analysis included).

Among the many factors likely to favour the occurrence of venous thromboembolism (VTE), exposure to certain drugs has to be taken into account. Although hormone treatments, oral contraception and hormone replacement therapy (HRT) for menopause have been studied, these are not the only drugs associated with an increased risk of VTE. The antipsychotics have also been incriminated in the occurrence of venous thromboembolism. The association of thalidomide and dexamethasone, used in the treatment of multiple myeloma, is responsible for a major increase in the risk of VTE. The physiopathological mechanisms accounting for the possible prothrombotic effect of most of these drugs is still not fully understood. Further observational and interventional clinical studies should provide a better understanding of VTE, potentially associated with drugs. However, certain drugs may be associated with a reduced risk of VTE. Although several studies indicate that aspirin and statins may favourably influence the risk of VTE, it is still not possible to draw up any practical recommendations.

INTRODUCTION: The revision of the French medical studies' third cycle ought to be competency-based. In internal medicine, theoretical and practical knowledge will be assessed online with e-learning and e-portfolio. In parallel, a reflection about clinical skills assessment forms is currently ongoing. In this context, our aim was to assess the reproducibility and validity of two assessment forms based on direct clinical observation. METHOD: A prospective and multicentric study has been conducted from November 2015 to October 2016 aiming at evaluating the French translations of the MINI-Clinical Examination Exercice (MINI-CEX) and the Standardized Patient Satisfaction Questionnaire (SPSQ). Included residents have been assessed 2 times over a period of 6 months by the same binoma of judges. RESULTS: Nineteen residents have been included. The inter-judge reproducibility was satisfactory for the MINI-CEX: intraclass coefficients (ICC) between 0.4 and 0.8 and moderate for the SPSQ: ICC between 0.2 and 0.7 with a good internal coherence for both questionnaires (Cronbach between 0.92 and 0.94). Significant differences between the distributions of the scores given by the judges and a significant inter-center variability have been found. CONCLUSION: If the absolute value of the scores should not be taken into account in the evaluation process given its high variability, it could be of interest for the follow-up of the progression in the competencies. These forms could support the residents' debriefing based on the general trends given by the scores.

PURPOSE: Few data are available on the prevalence and causes of hyponatremia in medical setting and to our knowledge, no recent descriptive study has been performed about hyponatremias in the French Departments of internal medicine. METHOD: A "one day" descriptive multicentric study was performed in the medicine departments of the France West area. A questionnaire was mailed to physicians who had to take part in a annual regional meeting about "hyponatremias", one month later. Hyponatremia was defined by a blood sodium level under the normal value of the local laboratory. Each internist had to precise for all hyponatremias in course at the study day, the exact value, the discovery circumstances, the mechanisms and etiologies, the associated diseases, the course and treatments. RESULTS: Seventy-four hyponatremias were identified. The overall prevalence was 12,1%. The prevalence of severe hyponatremias (under 120 mmol/l) was 1,1%. These latter represented 9,4% of the whole hyponatremias (7/74). Associated symptoms and diseases, the mechanisms, the suspected etiologies, the course and treatments are described in detail. CONCLUSION: This multicentric study reports for the first time the prevalence, the clinical and etiological characteristics of hyponatremias coming from Internal Medecine Departments of the West area from France. The overall prevalence is lower in comparison with values usually reported in hospitalized patients, but the frequency of severe and moderate hyponatremias, the mechanisms and the suspected etiologies are identical to those reported in others countries.

INTRODUCTION: Endobronchial stenoses are rare in the course of Wegener's granulomatosis, and they occur even more rarely than subglottic stenoses. EXEGESIS: We report seven cases of endobronchial stenoses in the setting of Wegener granulomatosis. Neither the pulmonary symptoms nor the systemic manifestations of vasculitis were specific. However 6/7 patients presented a wheezing or an hemoptysis. Bronchial endoscopy has permitted the diagnosis in all cases. Local evolution was cicatricial and symptomatic stenosis in 3 cases (42,8%). CONCLUSION: Thus these lesions must be research in any case of pulmonary abnormality in the course of Wegener's granulomatosis, because they may lead to a pejorative prognosis. Moreover general and local treatment must be given early (at the inflammatory stage). After this stage, the local treatments are difficult and not efficient.

PURPOSES: Ten to fifteen percent of granulomatous hepatitis are idiopathic. If symptoms like prolonged fever are present, empirical treatment is discussed. The goal of this study is to describe the empirical treatment proposed in this situation by French specialists of internal medicine. METHODS: We conducted a practice investigation among the French national society of internal medicine (SNFMI), using an anonymous questionnaire that related a case of idiopathic granulomatous hepatitis. This questionnaire was proposed to all French internists present at the SNFMI congress in June and December 2004. French specialists of internal medicine had to answer if they would prescribe an empirical treatment and if so, to specify this treatment. RESULTS: Thirty-six French specialists of internal medicine answered to the questionnaire. In the proposed situation, 89% of them initiate an empirical treatment. In 18/36 cases (50%), a first-line anti-tuberculosis empirical treatment is proposed (quadritherapy in 11 cases). In 7 cases (19%), an empirical treatment with prednisone, 0.4 mg/kg/d (N=1) and 1 mg/kg/d (N=6), would be prescribed. Seven internists (19%) would prescribe an empirical treatment with cyclins at the dose of 100 to 400 mg/d. Median duration of the empirical treatment would be 28 days (range: 8-252d). The evaluation parameters mentionned are: fever (69%), weight (59%), seric level of C-reactive protein (59%), and liver biology (53%). In case of failure of first-line empirical treatments, 69% of all questionned internists prescribe a second-line treatments: prednisone at the dose of 0.4 to 2 mg/kg/d (72%), anti-tuberculosis treatments (16%), cyclins 200 mg/d (12%), with a median duration of 28 days. Seven internists (19%) propose to combine two empirical treatments. DISCUSSION: Faced with a problem of idiopathic granulomatous hepatitis, French internists questionned propose four therapeutics options: no treatment, anti-tuberculosis treatment, cyclins or steroids treatment. First-line anti-tuberculosis treatment is a coherent proposition regarding to the high prevalence of tuberculosis. There are only few data available concerning empirical treatment with steroids or cyclins. Specific proposition of such empirical treatments should be defined. CONCLUSIONS: The management of idiopathic granulomatous hepatitis is difficult. Our study shows that therapeutics practices of French internists are heterogenous. The main proposition consists in a first-line anti-tuberculosis empirical treatment, that has to be evaluated after four weeks, and switched with steroids (prednisone, 1 mg/Kg/d) in case of failure. This study is not an expert proposition but contributes to suggest clinical practice guidelines for a rare, complex, heterogenous, and typically internist situation.

BACKGROUND: This study was designed in the context of a new educational program based on standardized-patients (SPs). The study objectives were (1) to evaluate the reliability of the assessment form used by SPs and (2) to compare global ratings to checklists reproducibility. METHOD: History taking, physical examination and communication skills were assessed by SPs at the end of clinical encounters with year 3 medical students, using generic global rating scales and case-specific checklists. The validation process followed four steps: (1) correlation analysis between global rating and their relative checklist of specific items, (2) internal consistency estimation, (3) validation of the questionnaire dimensions, (4) estimation of the reliability of SPs' ratings compared to medical teachers' ratings. RESULTS: A total of 3322 consultations have been performed by 444 year 3 medical students. Statistical analysis showed a good internal reliability (Cronbach α was greater than 0.7) and an acceptable inter-judge reproducibility except for communication skills. Case-specific checklists did not prove to be more reliable than global ratings. Reproducibility was lower with SPs' than with medical teachers' assessment. CONCLUSION: Global rating-based assessment should be preferred to checklists because they are faster and easier to use (shorter duration of SPs training). As SPs proved to be acceptable examiners, no third person seems to be required as external observer.

PURPOSE: Clinical reasoning and treatment challenges within the scope of general practice led to the development of an internal medicine assistance line provided by Nantes University Hospital. The primary outcome of this study was to describe callers' profile, their requests and answers provided. METHODS: A prospective, cross-sectional, observational, descriptive study was undertaken. For each call were identified the calling physician, her/his specialty and work setting, the call's object and adequacy, the answer provided, the time needed to connect with the assistance line, the time devoted by the internal medicine physician to provide an answer to the request, and whether the assistance line prevented a visit to the emergency room. Each calling physician was then called back to obtain demographic and professional characteristics, and data relating to the call and to the assistance line. RESULTS: Sixty-three days were analyzed and 276 calls identified. The 237 identified calling physicians were mainly females (54%, n=93), with a mean age of 46 years, graduated from Nantes University (65%, n=86), practicing ambulatory general medicine (69%, n=164) in Loire-Atlantique department area (82%, n=176) for a mean duration of 15 years. Calls were mostly associated with diagnostic challenges (61%, n=166) concerning clinical issues (57%, n=155). A sole telephone advice was the main type of answer provided (56%, n=147) and a visit to the emergency room was prevented for 17% of calls. CONCLUSION: The assistance line activity is adequate with its missions and seems to facilitate patients' healthcare delivery advocating for the development of similar structures in other units. Improvements relating to the information, availability and physicians' training should be considered.

In case of unprovoked venous thromboembolism (VTE), the screening of thrombophilia is recommended whatever the age of the patient and the type of risk factors (RF). This prospective study was conducted in patients with unprovoked VTE to detect some predictive factors to have a higher risk of thrombophilia, focusing on age, history of venous thromboembolism, and the existence of a triggering event. From July 2000 to July 2002, in an Internal Medicine Department, unrelated patients with unprovoked VTE were included. Those unprovoked thromboembolic events were defined by the absence of association between permanent and transient RF. The primary outcome measure was the positivity of the thrombophilia screening for any type of abnormality detected (deficit of protein C, S, antithrombin, presence of a lupus anticoagulant, research of V and II mutations). Seventy-four patients were included. Eight died during the follow-up. A higher risk of thrombophilia was found in patients younger than 40 (p=0.03), or with a family but not personal history of VTE (p=0.01) or with transient RF (p=0.02). The most frequent abnormality of coagulation found in patients younger than 40 was the presence of a lupus anticoagulant. As a new strategy for the screening of thrombophilia, one could propose the following attitude: only patients with transient RF or family history of VTE could undergo a complete screening; for all the remaining patients who are younger than 40, a research of a lupus anticoagulant would be only performed. This strategy should now be balanced against the currently recommended systematic attitude in further studies.

PURPOSE: The study looks for medical students ethical understanding during their internal medicine hospital rotations. As a secondary purpose, the study screens if internal medicine ward provides an environment appropriate for pregraduate medical students ethical training. METHOD: Retrospective analysis and comparison of logbook writings from 2 different pregraduate groups of students : Group A = 29, third year medical students and Group B = 28, sixth year medical students, (that is last year pre-graduation). The task instructions were the same for the two groups : to identify and to analyse an ethical problem personally witnessed on the ward and to propose a solution either local or personal. Cognitive semantic units (CSU) were first drawn from the writings then subsequently analysed through two grids 1* according to fundamental principles (P) and 2* according to professional responsibilities (R). RESULTS: Students from group A produced a mean of 13,7 CSU per writing (total of 396 CSU) and those from Group B, 7,3. (total of 205 CSU) ; significant difference with P <0,004 between the 2 groups. Both identification of ethical dilemma itself and outbreaking it in (P) and (R) items and articulating solutions were significantly different between the 2 groups(P <0,004 Wilcoxon). Patient-physician relationship was predominantly present in both groups. While end-of-life and therapeutic issues were more prominent among group B, students of group A disagreed more with staff. Students of group B focused on external causes to excuse their demotivation (final exams'preparation), being more fatalist than cynical towards ethical issues. CONCLUSION: There is an erosion of clinical ethical sensitivity during pregraduate training. This study shows that internal medicine hospital rotation provides enough opportunities (both in number and in variety) to promote keen clinical ethical learning.
