Appraisal of ChatGPT's Aptitude for Medical Education: Comparative Analysis With Third-Year Medical Students in a Pulmonology Examination.

BACKGROUND: The rapid evolution of ChatGPT has generated substantial interest and led to extensive discussions in both public and academic domains, particularly in the context of medical education. OBJECTIVE: This study aimed to evaluate ChatGPT's performance in a pulmonology examination through a comparative analysis with that of third-year medical students. METHODS: In this cross-sectional study, we conducted a comparative analysis with 2 distinct groups. The first group comprised 244 third-year medical students who had previously taken our institution's 2020 pulmonology examination, which was conducted in French. The second group involved ChatGPT-3.5 in 2 separate sets of conversations: without contextualization (V1) and with contextualization (V2). In both V1 and V2, ChatGPT received the same set of questions administered to the students. RESULTS: V1 demonstrated exceptional proficiency in radiology, microbiology, and thoracic surgery, surpassing the majority of medical students in these domains. However, it faced challenges in pathology, pharmacology, and clinical pneumology. In contrast, V2 consistently delivered more accurate responses across various question categories, regardless of the specialization. ChatGPT exhibited suboptimal performance in multiple choice questions compared to medical students. V2 excelled in responding to structured open-ended questions. Both ChatGPT conversations, particularly V2, outperformed students in addressing questions of low and intermediate difficulty. Interestingly, students showcased enhanced proficiency when confronted with highly challenging questions. V1 fell short of passing the examination. Conversely, V2 successfully achieved examination success, outperforming 139 (62.1%) medical students. CONCLUSIONS: While ChatGPT has access to a comprehensive web-based data set, its performance closely mirrors that of an average medical student. Outcomes are influenced by question format, item complexity, and contextual nuances. The model faces challenges in medical contexts requiring information synthesis, advanced analytical aptitude, and clinical judgment, as well as in non-English language assessments and when confronted with data outside mainstream internet sources.

Evaluation de l'enseignement par les étudiants : Exemple d'un atelier de simulation sur l'ECG.

INTRODUCTION: The electrocardiogram (ECG) is a fundamental tool in medical practice. At the Faculty of Medicine of Tunis (FMT), it is usually taught during a lecture. FMT's Physiology Department has innovated its teaching by introducing simulation workshops. AIM: This study aimed to assess the students' satisfaction with teaching ECG by simulation. METHODS: This was a cross-sectional descriptive study, carried out in April 2018, including 160 students in the first year of the first cycle of medical studies, divided into 10 groups. The students attended an ECG simulation workshop at the FMT media library and then answered a satisfaction form and a self-assessment questionnaire for the workshop. RESULTS: More than 50% of the students answered either satisfied or very satisfied with the duration of the course, the room, the method of the teacher, and their participation in the course of the session. Regarding teaching support, 19.3% of the students were very satisfied with the practice of the ECG on a mannequin versus 25% for the practice on a voluntary student. For the number of students per group, 42.1% of students were dissatisfied. CONCLUSION: This study highlights the weak points of this simulation workshop in order to improve it. Then, it helps to build students' confidence and encourage their adherence to the feedback process. Finally, it shows students' enthusiasm for new teaching methods such as simulation. It would be interesting to generalize this evaluation process for the improvement of medical education and the training of future doctors.

Prevalence of indeterminate tuberculosis interferon-gamma release assays in COVID-19 patients: Systematic review and meta-analysis.

Background and Aims: The reliability of interferon-gamma-release-assays (IGRAs) for tuberculosis (TB) testing in coronavirus disease 2019 (COVID-19) patients is unknown. This study aimed to systematically review the prevalence of indeterminate TB-IGRA following SARS-CoV-2 infection or vaccination and to review associated factors. Methods: This systematic literature review was guided according to the PRISMA guidelines by searching PubMed, Scopus, Web of Science, Clinicalkey, and Cochrane Library. Studies reporting results of TB-IGRA tests (QuantiFERON [QFT]-TB, T-SPOT.TB) in COVID-19 patients or vaccines were included. The random effects model was used to assess the prevalence of indeterminate IGRA results. Heterogeneity was evaluated using the Τ 2 and 95% predictive interval. Results: Of the 273 citations screened, 12 articles were included in the final analysis including a total of 2107 patients. The overall pooled effect size proportion of indeterminate QFT-TB results, estimated in eight studies using the QFT-TB Plus assay, was 0.26 (95% CI: 0.205-0.324, Τ 2 = 0.158). The mean true effect size was 0.26 (95% predictive interval: [0.110-0.500]). A subgroup analysis was not undertaken due to the small number of studies. Indeterminate QFT-TB rates were associated with COVID-19 severity, steroid treatment, inflammation-related parameters, neutrophilia, and lymphopenia. Conclusion: Indeterminate QFT-TB results in COVID-19 patients occur in almost one-quarter of tests performed. Further studies are needed to assess associated factors.

Impact of respiratory muscle training on clinical and functional parameters in COVID-19 recovered patients.

Introduction: early respiratory rehabilitation is required for patients with coronavirus virus disease 2019 (COVID-19) sequelae to reduce the risk of serious disabilities after hospital discharge. Methods: it was a comparative prospective study including patients with persistent symptoms one month after discharge. The patients were hospitalized at the pneumology department D of Abderahman Mami hospital for COVID-19 pneumonia. The study involved two groups: (G1) included patients who participated in respiratory muscle training program (twice a week during 6 weeks), and a control group (G2). The groups were matched based on age, sex and body mass index (BMI). Persistent symptoms and pulmonary lung function (forced vital capacity (FVC), forced expiratory volume in one second (FEV1), total lung capacity (TLC) and diffusion capacity for carbon monoxide (DLCO), maximal inspiratory pressure (PI max) and maximal expiratory pressure (PE max), 6 Minute Walk distance (6-MWD) at baseline and after 6 weeks were compared between the two groups. Results: the two groups of patients were comparable in terms of age, sex, BMI, comorbidities, and extent of lung computed tomography (CT) lesions. Compared to G2, a significant improvement of persistent symptoms was noted in G1, including dry cough (p=0.002), dyspnea (p=0.001), chest pain (p=0.002), and fatigue (p=0.001). The mean of percutaneous oxygen saturation (SpO2) increased from 96.68% to 97.93% (p<0.01) in G1. A significant improvement in the percentages of change of FEV1 (p=0.005), FVC (p=0.003), TLC (p<0.001), DLCO (p<0.001), and 6-MWD (p=0.015) was also noted in G1 after this program. Nevertheless, only the percentage of FEV1 (p=0.02) increased in the control group. No impact of respiratory muscle training on PI max and PE max was noted. Conclusion: the present study demonstrated a significant improvement of persistent symptoms and exercise tolerance after short-term respiratory muscle training in patients suffering from COVID-19 sequelae.

Cost analysis of a medical procedure using the full cost method: The example of a trans-thoracic scan-guided biopsy.

INTRODUCTION: Trans-thoracic scan-guided biopsy (TTB) is a crucial examination for exploring thoracic lesions, particularly in the case of tumor pathologies. To make informed decisions in cost-effectiveness analyses, it is important to understand the actual costs of this procedure. AIM: To quantify the cost of performing TTB using a microeconomic approach. METHODS: We used the full cost method, which is the reference method in cost accounting. This method subdivides costs into direct and indirect costs. Direct costs are divided into variable and fixed components. Variable costs include consumables and wages of personnel involved in the "labor" act. Fixed direct costs are those that do not vary during the study period; they include the costs of purchasing, depreciation, maintenance, and repair of the scanner room equipment. Indirect costs include overhead costs that cannot be directly attributed to the TTB procedure. RESULTS: The total direct cost of the TTB procedure amounts to 310.191 TND when using a coaxial and 256.390 TND in the absence of a coaxial, including fixed and variable costs. Indirect costs were not included in this study due to the absence of cost accounting at the hospital. CONCLUSION: Accurate knowledge of the costs of any medical procedure is essential for making informed decisions in cost-effectiveness analyses. This study provides a precise estimate of the direct costs of TTB and can help improve the efficiency of resource allocation for performing this procedure.

Risk factors for rheumatoid arthritis-associated interstitial lung disease: a retrospective study.

Background: The objective of this study was to assess clinical and imaging features of rheumatoid arthritis (RA) associated with interstitial lung disease (ILD), (RA-ILD) group, in comparison to RA without ILD (RA-C) and to identify the associated factors to ILD. Methods: This was a retrospective comparative study (from June 2015 to March 2022) including RA patients aged ≥18 years. The RA-C control group was matched according to age (±2 years), gender, and RA duration (±2 years). General data, RA characteristics, ILD features, and treatment modalities were recorded. Statistical analysis was performed to determine the predictive factors of ILD. Results: A total of 104 patients were included (52 RA-ILD and 52 RA-C); sex ratio was 0.36. Mean age was 66.3±11 years (RA-ILD) versus 65.6±10.8 years (RA-C) (p=0.72). In comparison to RA-C, RA-ILD patients were significantly higher smokers (p=0.01) and physically inactive (p=0.01). Regarding RA features, RA-ILD patients have significantly increased positive anti-citrullinated peptide antibody (ACPA) (p=0.01), ACPA rate (p<0.001), erosive disease (p<0.001), and disease activity score (p<0.001). Mean time to ILD diagnosis was 5.85±7.16 years. Chest high-resolution computed tomography (HRCT) patterns of disease were identified: nonspecific interstitial pneumonia (NSIP) (28.8%), usual interstitial pneumonia (UIP) (17.3%), organizing pneumonia (OP) (25%), acute interstitial pneumonia (13.5%), and respiratory bronchiolitis (3.8%). Multivariate analysis identified smoking, high baseline DAS28 (disease activity score 28) and ACPA positivity as predictive factors of ILD. Conclusion: Our results confirmed the reported associated factors of ILD in RA (smoking, higher disease activity, ACPA positivity). Thus, we need to target the modifiable factors by supporting and educating RA patients to quit smoking and intensify disease modifying anti-rheumatoid drugs (DMARD) to reach remission.

Paradoxical bronchoconstriction caused by ß2-adrenoceptor agonists.

INTRODUCTION: Salbutamol and terbutaline are short-acting ß2 adrenergic agonists that produce bronchial smooth muscle relaxation and are widely used in obstructive pulmonary diseases. Nevertheless, their use has been the cause of a paradoxical bronchoconstriction, which is a rare and potentially serious adverse reaction. The aim of this study is to report a case of paradoxical bronchoconstriction caused by ß2 adrenergic agonists. METHODS: This case is about a 50-year-old asthmatic patient who describes a history of repeated acute asthma attacks after salbutamol inhalation or terbutaline nebulization. A double-blind crossover study was performed over 3 days, in order to compare the effects of each bronchodilator. Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and maximal expiratory flow 25-75 (MEF25-75) were measured. RESULTS: On the first day, a bronchoconstriction caused by deep and repeated inhalations was eliminated. On the second day, an airway obstruction was confirmed by a decrease in FEV1 at 40% from baseline values after nebulization of a standard dose of terbutaline. On the third day, a spirometry was performed before and after nebulization of a standard dose of ipratropium bromide, and there were no significant changes in the spirometric parameters. Finally the patient was discharged with a written warning mentioning the danger of salbutamol and terbutaline use. CONCLUSION: Salbutamol and terbutaline are generally well-tolerated ß2 adrenergic agonists. Nevertheless, in rare cases, these substances can cause a paradoxical bronchoconstriction. Doctors must therefore remain vigilant about its side effect and possibly investigate each case.
