Mini-entretiens multiples : un outil pour la réforme de l’accès aux études en santé en France

Introduction : Depuis la loi de santé de 2019, les modalités d’accès aux études en maïeutique, médecine, odontologie et pharmacie comportent des épreuves écrites et, pour une partie des étudiants, au moins une épreuve orale. Les mini-entretiens multiples (MEM) permettent d’évaluer les capacités de communication, l’empathie ou les capacités de travail en groupe et sont moins biaisés que les entretiens individuels traditionnels. Cet article propose une revue narrative de la littérature afin d’évaluer la faisabilité des MEM dans le contexte français. Méthodes : Cet article de synthèse s’appuie sur une recherche bibliographique à partir de la base PubMed avec le mot clé « Multiple Mini Interview ». Les articles sélectionnés devaient traiter au moins une des questions suivantes relatives aux MEM : organisation, acceptabilité, compétences évaluées, prédiction des performances. Résultats : Les MEM ont été utilisés pour la sélection des candidats à de nombreuses filières en santé et dans de nombreux pays. Les résultats obtenus aux MEM à l’admission sont corrélés aux performances obtenues lors des stages cliniques et des ECOS durant le cursus universitaire. Cependant, certaines caractéristiques des candidats peuvent influer les résultats obtenus (âge, facteurs socio-économiques) et les MEM mobilisent de nombreux évaluateurs pour leur mise en œuvre. Conclusion : Les MEM sont une modalité d’évaluation reproductible et validée pour la sélection des étudiants en santé, en complément de l’évaluation des aptitudes cognitives. Ils devraient être largement utilisés pour la sélection des étudiants en santé en France, depuis la réforme de l’accès aux études en santé

BMP system expression in GCs from polycystic ovary syndrome women and the in vitro effects of BMP4, BMP6, and BMP7 on GC steroidogenesis.

International audienceBACKGROUND:The bone morphogenetic proteins (BMPs) are growth factors involved in the folliculogenesis. Alteration in their expression may compromise the reproductive process in disease such as the polycystic ovary syndrome (PCOS). This study investigated the expression and role of granulosa cell (GC) BMP from normal cycling and PCOS women.METHODS AND RESULTS:This prospective study was performed in GCs obtained from 14 patients undergoing IVF: i) six women with normal ovulatory cycles and tubal or male infertility and ii) eight women with PCOS. BMP2, BMP4, BMP5, BMP6, BMP7, and BMP8A and their receptors BMPR1A, BMPR1B, and BMPR2 were identified by RT-PCR in GCs from normally cycling and PCOS women. BMP4, BMP6, and BMP7 expressions were confirmed by immunohistochemistry. Quantitative transcript analysis showed the predominant expression of BMP6. In GCs from PCOS women, an overexpression of BMP6 (P<0.01) and BMPR1A mRNA (P<0.05) was observed. GC culture experiments demonstrated that basal estradiol (E₂) production was threefold higher but FSH-induced E₂ increment was twofold lower in PCOS compared with controls. In PCOS, BMP6 and BMP7 exerted a stimulatory effect on basal E₂ production while BMP4 and BMP6 inhibited FSH-induced E₂ production. FSH receptor and aromatase expression were not different between both groups.CONCLUSION:The BMP system is expressed in human GCs from normal cycling and PCOS women. The BMP may be involved in reproductive abnormalities found in PCOS

Major hyperestrogenism in a feminizing adrenocortical adenoma despite a moderate overexpression of the aromatase enzyme.

International audienceA 30-year-old male was referred for the rapid development of gynecomastia, and dramatic hyperestrogenemia was assessed: plasma estrone, estradiol but also cortisol were not suppressed by high-dose dexamethasone, while gonadotropin pulsatility was completely abolished. A 60-mm right adrenal tumor was evidenced on computed tomography-scan, and the patient underwent adrenalectomy. The tumor was found to express a moderate increase in aromatase activity compared with adjacent non-neoplastic adrenal tissue. Quantitative RT-PCR also showed a weak and non-significant increase in total aromatase mRNA in the tumor compared with normal adrenal tissue. Aromatase transcripts were mainly promoter PII-derived, but different patterns of aromatase minor transcripts were found: promoter I.3- and I.6-derived transcripts were identified in the tumor, while only promoter I.4-derived transcripts were found in normal adrenal. This case report demonstrates that a sharp aromatase overexpression is not a prerequisite for clinical and biochemical hyperestrogenism, and further characterizes the aromatase promoter utilization in this feminizing adrenocortical tumor and in the normal adrenal cortex

Pregnancies and obstetrical prognosis after oocyte donation in Turner Syndrome A multicentric study

International audienceIntroduction - Turner syndrome is one of the most frequent chromosomal abnormalities in women, with a prevalence estimated to be 1 of 2500 live birth. Pregnancy in women with Turner syndrome is known to be at high risk, whether it is spontaneous or after oocyte donation, because of miscarriages and potential cardio-vascular complications which can be life-threatening. All of these patients should therefore be screened with a comprehensive cardio-vascular assessment before pregnancy, and have a close follow-up during and after pregnancy.Patients and methods - It is a retrospective study, conducted in 10 of the 27 French oocyte donation centers between 2012 and 2016, on all the patients presenting with Turner syndrome included in an oocyte donation program.Results - 151 embryo transfers were realized in 73 patients, resulting in 39 pregnancies. Among these pregnancies, 24 children were born healthy, 11 spontaneous miscarriages, 3 voluntary abortions, 1 extra-uterine pregnancy and 1 maternal death from non-cardio-vascular origin occurred. Pregnancies were complicated by gravid arterial hypertension in 28.2% of cases, preeclampsia in 10.3% of cases, and gestational diabetes in 7.7% of cases.Conclusion - This study bring out obstetrical complications of the same magnitude than the ones described in the literature. Lead over a period of 4 years, in 10 French oocyte donation centers, it doesn't reveal any cardio-vascular complications, conversely to other studies published before French and American recommendations. This study reinforces the usefulness of specific recommendations for the care of these particular patients
