Socio-Cultural Perceptions and Representations of Dementia in Brazzaville, Republic of Congo: The EDAC Survey
Background: Dementia will concern more and more people in the developing countries, but the perception people have of dementia in these areas has not yet been studied. Method: During a general population survey (EDAC) carried out in Brazzaville (Republic of Congo), 27 elderly persons suspected of having dementia and 31 of their relatives, 90 cognitively impaired elderly persons and 92 of their relatives, as well as 33 hospital workers were interviewed according to the Explanatory Model Interview Catalogue. Results: Item prominence ratings indicate that the attention was mainly on the emotional and socio-economic consequences (scores >1.0 out of 5 points). Ageing and mental stress are the main perceived causes. Hospital workers are more aware of public stigma. Conclusion: The socio-cultural components of the dementia phenomenon have to be taken into account to enforce public health and social measures
Prospective study on a fast-track training in psychiatry for medical students: the psychiatric hat game
Abstract: Background: While medical students are losing interest in lectures in favor of other educational materials, many studies suggest the benefit of active learning, combined with gamified educational tools. The authors developed a psychiatric adaptation of the « Hat Game ». It was hypothesised that this game would increase both knowledge and motivation in medical students toward psychiatric semiology. The aim of the study was to assess the benefit of a Psychiatric Hat Game session for learning psychiatric symptoms in third-year medical students. Student performance was also evaluated at 3 months. Methods: This gamified fast-track training consists of two teams and each team has to guess as many psychiatric semiology terms as possible using different techniques (i.e. speech, mime). The study involved a pre- and post-evaluation of knowledge (Multiple Choice Questions) and a satisfaction survey. Baseline, post-immediate, and three-months scores were compared by using Friedman analysis for paired samples. Comparisons of mean scores at two different times were performed by using Wilcoxon test for paired samples. Results: One hundred and sixty-six students were proposed to take part in the study. Among them 129 completed the whole program (response rate = 77.7%). Mean scores measured at the three points in time were significantly different (p < 0.001, N = 129). Knowledge mean scores were significantly higher after the game than before (+ 28.6%, p < 0.001). Improvement was maintained 3 months after the game (+ 18.9%, p < 0.001). Satisfaction survey items highlighted that students enjoyed and would recommend this type of gamified training. Conclusions: The Psychiatric Hat Game improved knowledge of psychiatric semiology in medical students. Results suggest that it is a promising and efficient tool to playfully teach medical semiology, with transferable features, utility and acceptability from one medical field to another. This study contributes to the growing body of knowledge advocating for serious games and gamified training in medical education.Version of Recor
Traumatic Brain Injury: An Age-Dependent View of Post-Traumatic Neuroinflammation and Its Treatment
Traumatic brain injury (TBI) is a leading cause of death and disability all over the world. TBI leads to (1) an inflammatory response, (2) white matter injuries and (3) neurodegenerative pathologies in the long term. In humans, TBI occurs most often in children and adolescents or in the elderly, and it is well known that immune responses and the neuroregenerative capacities of the brain, among other factors, vary over a lifetime. Thus, age-at-injury can influence the consequences of TBI. Furthermore, age-at-injury also influences the pharmacological effects of drugs. However, the post-TBI inflammatory, neuronal and functional consequences have been mostly studied in experimental young adult animal models. The specificity and the mechanisms underlying the consequences of TBI and pharmacological responses are poorly understood in extreme ages. In this review, we detail the variations of these age-dependent inflammatory responses and consequences after TBI, from an experimental point of view. We investigate the evolution of microglial, astrocyte and other immune cells responses, and the consequences in terms of neuronal death and functional deficits in neonates, juvenile, adolescent and aged male animals, following a single TBI. We also describe the pharmacological responses to anti-inflammatory or neuroprotective agents, highlighting the need for an age-specific approach to the development of therapies of TBI
“Pharmacotrophy”: a playful tournament for game- and team-based learning in pharmacology education - assessing its impact on students’ performance
Abstract Background At the Faculty of Pharmacy of Paris, we conducted a pharmacology tournament in 2021 and 2022, named “Pharmacotrophy”, to offer a game-, team- and competitive-based learning innovation based on fun and challenge. This article aims to (1) provide a detailed overview of the organisation of “Pharmacotrophy,” (2) present and compare feedback from both students and teachers, and (3) assess the impact of student participation on their exam marks. Methods “Pharmacotrophy” took place in 2021 and 2022 over a two-week period at the beginning of the exam revision phase. It involved a combination of remote matches using the online quiz creation tool Kahoot!® and in-person matches. Teams, consisting of three students from the 4th or 5th year, participated in several selection rounds leading up to the final match. The questions covered various topics from the pharmacology curriculum. Using an anonymous online survey, we collected the feedback from students and teacher regarding the organisation of the tournament and the interest and difficulty of the different type of questions. We retrospectively compared the exam marks of 4th year students who took part in “Pharmacotrophy” (n2021 = 19 and n2022 = 20) with those of the rest of the 4th year (n2021 = 315–320 and n2022 = 279–281), both in the year before “Pharmacotrophy” and just after the tournament. Results Students highlighted the educational benefits of team-based and game-based learning. This novel approach positively and constructively motivated students to review pharmacology. Additionally, students appreciated the establishment of a trust-based relationship with their teachers. All students had a similar pharmacology level based on their exam results in the year before “Pharmacotrophy.” After the tournament, participants had marks 20.1% higher in pharmacology questions compared to non-participants (p = 0.02), while they had comparable overall levels, as evidenced by their final grade averages and marks in non-pharmacology questions. Moreover, participants who advanced further in the competition achieved higher marks in pharmacology questions compared to those who were eliminated early in the tournament. Conclusion The implementation of “Pharmacotrophy” provided students with an enjoyable way to review pharmacology coursework and revived the interest in pharmacology for some. Specifically, participating in “Pharmacotrophy” led to an increase in pharmacology marks for students who were not among the top performers in the class or did not excel in pharmacology in the previous year. This study quantified the pedagogical value of this innovative curriculum in terms of knowledge acquisition
Lamotrigine in mood disorders: Flash survey on prescribing habits and blood tests practices
Objective: Therapeutic drug monitoring for lamotrigine is poorly documented in bipolar and depressive disorders. In order to evaluate its use among French psychiatrists, we explored prescribing habits, therapeutic monitoring and dosage adjustment of lamotrigine through a flash survey.Methods: A survey was broadcasted by the network of Expert Centers for Bipolar Disorder and Resistant Depression and by the Collegial of Psychiatry of the Assistance publique des HĂ´pitaux de Paris. Questions concerned the frequency of prescribing depending on the mood disorder, the frequency of plasma levels, therapeutic monitoring, dosage adjustment and the limitation represented by dermatological risk.Results: Of the 99 hospital psychiatrists who responded, 66 practiced in a university hospital and 62 for more than 5years. Overall, lamotrigine was more frequently prescribed for type 2 bipolar disorder (often: 51%) than for type 1 bipolar disorder (often: 22%). Dermatotoxicity was a major barrier to prescribing for 15% (n=13) of respondents. Nearly two-thirds of prescribers (61%, n=59) measured lamotrigine, of which 50% (n=29) systematically. However, 40% of them did not have an opinion on the optimal plasma concentration. In total, 22% (n=13) always adjusted the dosage according to the result. The first argument for dosage adjustment was clinical response for 80% (n=47) of prescribers, adverse effects for 17% (n=10) and plasma levels for only 4% (n=2).Conclusion: While many psychiatrists report using plasma dosage of lamotrigine, few use the plasma level result to adapt dosage and many have no opinion of the target values for plasma concentrations. This illustrates the lack of data and recommendations regarding the use of therapeutic pharmacological monitoring of lamotrigine in bipolar and depressive disorders

Valproate, divalproex, valpromide: Are the differences in indications justified?
International audienceIn many countries, valproate is indicated for epilepsy only, whereas its derivative divalproex (DVP) and valpromide (VPM) are indicated for bipolar disorders only. DVP is composed of sodium valproate and valproic acid (VA) in a 1:1 molar ratio and VPM is a prodrug completely hydrolyzed in the gastric tract to VA. Whatever the drug, the absorbed and active substance is the valproate ion. In this article, we reviewed the potential reasons that might justify these different indications. We performed a literature review of comparative studies of efficacy, pharmacokinetic parameters, side effects and costs for VPA, DVP, and VPM. We found only studies comparing VA with DVP. None of the eight efficacy studies found differences in epilepsy or mood disorders. The ten studies of side effects reported a difference in terms of gastrointestinal effects, but inconsistently. The United States (US) summary of product characteristics and kinetic comparison studies reported bioequivalence between DVP and VA, but a longer Tmax for DVP, likely due to its gastro-resistant galenic form. VPM summary of product characteristics and pharmacokinetic studies revealed a lower bioavailability (80% vs. 100% for VA) and a delayed Tmax. There is an additional cost for using DVP or VPM as compared to VA (respectively +177% and +77% in France). The differences in indications between valproate derivatives do not seem justified. Interchangeability between VA and DVP in bipolar disorders seems possible, at identical dosage. VPM would require a closer dosing schedule and a 20% reduction in dosage when switching to valproate
