The value of formative objective structured clinical examinations (OSCEs) during the pre-clinical years of medical education remains unclear. We aimed to assess the effectiveness of a formative OSCE program for medical students in their pre-clinical years on subsequent performance in summative OSCE. We conducted a non-randomized controlled prospective pilot study that included all medical students from the last year of the pre-clinical cycle of the Université Paris-Cité Medical School, France, in 2021. The intervention group received the formative OSCE program, which consisted of four OSCE sessions, followed by debriefing and feedback, whereas the control group received the standard teaching program. The main objective of this formative OSCE program was to develop skills in taking a structured medical history and communication. All participants took a final summative OSCE. The primary endpoint was the summative OSCE mark in each group. A questionnaire was also administered to the intervention-group students to collect their feedback. A qualitative analysis, using a convenience sample, was conducted by gathering data pertaining to the process through on-site participative observation of the formative OSCE program. Twenty students were included in the intervention group; 776 in the control group. We observed a significant improvement with each successive formative OSCE session in communication skills and in taking a structured medical history (p<0.0001 for both skills). Students from the intervention group performed better in a summative OSCE that assessed the structuring of a medical history (median mark 16/20, IQR [15; 17] versus 14/20, [13; 16], respectively, p = 0.012). Adjusted analyses gave similar results. The students from the intervention group reported a feeling of improved competence and a reduced level of stress at the time of the evaluation, supported by the qualitative data showing the benefits of the formative sessions. Our findings suggest that an early formative OSCE program is suitable for the pre-clinical years of medical education and is associated with improved student performance in domains targeted by the program.

Background Despite widespread vaccination programs, pertussis continues circulating within populations and remains a life-threatening infection in infants. While several mortality risk factors have been described, a comprehensive synthesis is lacking. We conducted a meta-analysis of studies investigating mortality risk factors in Pertussis infections and validated those factors in a large cohort. Methods Observational studies published in English were systematically searched in PubMed, EMBASE, and LiSSa databases from 01/2000 to 06/2024. The search yielded 816 unique citations. The primary outcome was mortality before discharge from the Pediatric Intensive Care Unit (PICU). Two independent reviewers assessed the risk of bias and extracted data. A REML-random effect model was used to calculate pooled prevalence and conduct the analysis. The identified risk factors were subsequently evaluated in a monocentric cohort of patients admitted to a tertiary hospital’s PICU for severe pertussis between January 1996 and December 2020. Data analysis was conducted between June and August 2024. Results Seventeen studies, including 2,725 patients, met the inclusion criteria. The pooled prevalence of mechanical ventilation, continuous renal replacement therapy, and Extracorporeal Membrane Oxygenation support were 55% (95% CI: 40–70; I 2  = 98), 15% (95% CI: 3–27; I 2  = 95), and 8% (95% CI: 3–12; I 2  = 93), respectively. The pooled mortality incidence was 19% (95% CI:12–26; I 2  = 96). Identified mortality risk factors included elevated heart rate, presence of pulmonary hypertension, presence of seizures, and elevated white blood cell (WBC) count. Validation in an 83-patient cohort (median age: 45 days, IQR: 30–55) revealed a mortality rate of 12%. Risk factors identified in the meta-analysis were significantly associated with non-survival in the cohort. A mortality prediction score was developed incorporating age < 30 days, heart rate > 200/min, and WBC > 30 G/l, achieving an area under the curve of 0.92 (95% CI: 0.86–0.99). Conclusion This meta-analysis identified a simple yet effective score to assess the severity of pertussis infection in infants admitted to PICU. Accurate risk stratification may enable timely treatment of critically ill patients, potentially improving outcomes.

Infantile regurgitation is one of the most common discomforts in the first months of life. Infantile colic and, in older children, functional dyspepsia have been linked to migraine. To date, this is the first study to investigate a possible association between infantile regurgitation and primary headaches in children. This is a case–control study of 195 children aged 6–17 years, with primary headache (migraine, or tension type headache) in 5 European paediatric hospitals. The control group is composed of 240 same-aged children attending with minor injuries during the same period — February 1st 2020 to December 1st 2020. A structured questionnaire identified a history of infantile regurgitation and other functional gastrointestinal disorders for case and control participants. The outcome was the difference in the prevalence of infantile regurgitation among children with or without a diagnosis of primary headache. The analysis showed a significant association between infantile regurgitation and migraine (OR = 1.88, CI 95 = 1.01–3.4, p = 0.04). No association was found between infantile regurgitation and tension type headache (p = 0.33). Subgroup analysis confirmed that the association was only significant for migraine without aura (OR = 2.3, CI 95 = 1.2–4.4, p = 0.01). In a further subgroup analysis, the presence of functional dyspepsia, irritable bowel syndrome and abdominal migraine was associated with migraine without aura.Conclusion: The presence of migraine among children aged 6–17 was associated with a history of infantile regurgitation. Additional longitudinal studies are required to confirm whether infantile regurgitation could be considered as a precursor of migraine.What is Known:• Children suffering from functional gastrointestinal disorders are more likely to be suffering from migraine and tension-type headache as well.• Children suffering from primary headache are more likely to have had infantile colic in their first six month of life.What is New:• It is the first study to find an association between migraine and infantile regurgitation in children.• These findings could have an impact on the diagnosis and therapeutics of both migraine and infantile regurgitation.
