Psychiatric and psychological follow-up of undergraduate and postgraduate medical students: prevalence and associated factors. Results from the national BOURBON study. Running title: mental health and addictive behavior of medical students

International audienceBackgroundPhysicians are at risk of burnout, anxiety and depression. Prevention is needed from the beginning of the medical studies to detect early poor mental health outcomes.ObjectiveTo determine the prevalence and associated of psychiatric or psychological follow-up in a national sample of undergraduate and postgraduate medical students (UPMS).MethodsUPMS of the 35 French Medicine faculties were recruited through mailing lists and social networks between December 2016 and May 2017 and fulfilled Internet anonymised questionnaires.ResultsOverall, 10,985 UPMS were included in the present study (2165 (19.7%) postgraduate, 31.6% males, mean aged 21.8 years). Overall, 1345 (12.2%) were followed-up by a psychiatrist and/or a psychologist, 20.5% of them were regular anxiolytic consumers and 17.2% of them were regular antidepressant consumers. In multivariate analyses, being followed-up by a psychiatrist and/or psychologist was associated with older age (aOR = 1.2[1.2–1.2], p < 0.0001), female gender (aOR = 0.5[0.5–0.7], p < 0.0001), current alcohol use disorder (aOR = 1.3[1.3–1.5], p < 0.0001), higher anxiolytic (aOR = 3.1[2.5–3.7],p < 0.0001) and antidepressant (aOR = 11.7[7.6–18.0],p < 0.0001) consumption, and with lower self-reported general health, social functioning and mental health quality of life (all aORs = 0.9, all p < 0.05). The UPMS followed-up by psychiatrist and/or psychologist reported to have been more frequently exposed to sexual assault (5.1% vs. 0.9%, aOR = 2.5[1.3–4.7], p < 0.0001), domestic violence (3.3% vs. 0.8% aOR = 2.1[1.2–4.0], p = 0.01) and parents divorce (11% vs. 6.4%, aOR = 1.5[1.2–1.9], p = 0.001). Students followed-up by a psychiatrist and/or psychologist reported more frequently to seek alleviating anxiety (aOR 1.9[1.6–2.3], p < 0.0001), depression (aOR 1.7[1.3–2.1],p < 0.0001), coping with studies difficulties (aOR 1.5[1.2–1.8],p < 0.0001), experiencing more stress at hospital (aOR = 2.3[1.6–3.5],p < 0.001) and more burnout syndrome (aOR = 1.4[1.1–1.8], p = 0.03).ConclusionsAround 12% of UPMS are followed-up by a psychiatrist and/or a psychologist. These students reported higher antidepressant and anxiolytic consumption, psychic suffering and altered quality of life, associated with professional pressure and personal issues. Public health programs should be developed to help these students through their studies to prevent later mental /addictive issues and professional suffering. Improving UPMS mental health may also improve the later quality of care of their patients and global stress at hospital

Improving the treatment and remission of major depression in homeless people with severe mental illness: the multicentric French Housing First (FHF) program. French Housing First Study Group Running title: Major depression in homeless people with severe mental disorders

International audienceObjectiveThe aim of this study was to investigate the factors associated with violent behavior in a large multicenter sample of Homeless Schizophrenia (SZ) and Bipolar Disorder (BD) (HSB) subjects.MethodsThis multicenter study was conducted in 4 French cities: Lille, Marseille, Paris and Toulouse. Violent behavior was defined by at least one episode of verbal or physical violence in the last 6 months.ResultsOverall, 675 HSB patients, mean aged 38 years and 82.5% men were included, 458 SZ (68.4%) and 212 BD (31.6%). During the 6 months before evaluation, 213 (34.3%) committed at least one physical or verbal violence. In multivariate analysis, violence has been associated with younger age (aOR = 0.96[0.94–0.99], p = .001), number of nights in the street (aOR = 1.01[1.01–1.01]), BD diagnosis (aOR = 1.63[1.01–2.65], p = .04), higher current illness severity (CGI score) (aOR = 1.32[1.07–1.64], p = .01), higher rates of current manic episode (aOR = 2.24[1.32–3.81], p = .002), current alcohol use disorder (aOR = 2.05 [1.33–3.15], p = .001), antisocial personality disorder (aOR = 2.51[1.55–4.07], p < .001) and with antidepressant consumption (aOR = 2.01[1.01–4.04], p = .04). No specific antipsychotic or mood stabilizer has been associated with decreased rates of violent behavior, however clozapine, lithium and carbamazepine remained poorly prescribed.ConclusionIn case of violent behavior in HSB subjects, clinicians should focus in priority on the treatment of mania, antidepressant iatrogenic effect and alcohol use disorder by pharmacological and non-pharmacological treatments. Clozapine, lithium and carbamazepine should be chosen as the treatments of reference in this population but may be hard to manage in some cases.The current clinical trial number is NCT01570712

Standardization of pre-analytical variables in plasma microparticle determination: results of the International Society on Thrombosis and Haemostasis SSC Collaborative workshop

Microparticles (MP) are sub-micron sized vesicles released by activated or apoptotic cells. They are generally defined as 0.1 to 1 μm membrane particles that expose the anionic phospholipid phosphatidylserine (PS) and membrane antigens representative of their cellular origin [1]. It is now well recognized that MP behave as vectors of bioactive molecules, playing a role in blood coagulation, inflammation, cell activation and cancer metastasis. In clinical practice, circulating MP originating from blood and vascular cells are elevated in a variety of prothrombotic and inflammatory disorders, cardiovascular diseases, autoimmune conditions, infectious diseases and cancer [1-3

Predictive value of dorso-lateral prefrontal connectivity for rTMS response in treatment-resistant depression: A brain perfusion SPECT study

Background: Previous clinical trials have suggested that repetitive transcranial magnetic stimulation (rTMS) has a significant antidepressant effect in patients with treatment resistant depression (TRD). However, results remain heterogeneous with many patients without effective response. / Objective: The aim of this SPECT study was to determine before treatment the predictive value of the connectivity of the stimulated area on further rTMS response in patients with TRD. / Methods: Fifty-eight TRD patients performed a brain perfusion SPECT before high frequency rTMS of the left dorsolateral prefrontal cortex (DLPFC). A voxel based-analysis was achieved to compare connectivity of the left DLPFC in responders and non-responders using inter-regional correlations (p < 0.005, corrected for cluster volume). A multiple logistic regression model was thereafter used with the goal of establishing a predictive score. / Results: Before rTMS, responders exhibited increased SPECT connectivity between the left DLPFC and the right cerebellum in comparison to non-responders, independently of age, gender, severity of depression, and severity of treatment resistance. The area under the curve for the combination of these two SPECT clusters to predict rTMS response was 0.756 (p < 0.005). / Conclusions: SPECT connectivity of the left DLPFC predicts rTMS response before treatment

BMC Nephrol

BACKGROUND: To describe the quality of life of adolescents initiating haemodialysis, to determine the factors associated with quality of life, and to assess coping strategies and their impact on quality of life. METHODS: All adolescents initiating haemodialysis between September 2013 and July 2015 in French paediatric haemodialysis centres were included. Quality of life data were collected using the "Vecu et Sante Percue de l'Adolescent et l'Enfant" questionnaire, and coping data were collected using the Kidcope questionnaire. Adolescent's quality of life was compared with age- and sex-matched French control. RESULTS: Thirty-two adolescents were included. Their mean age was 13.9 +/- 2.0 years. The quality of life score was lowest in leisure activities and highest in relationships with medical staff. Compared with the French control, index, energy-vitality, relationships with friends, leisure activities and physical well-being scores were significantly lower in haemodialysis population. In multivariate analyses, active coping was positively associated with quality of life and especially with energy-vitality, relationships with parents and teachers, and school performance. In contrast, avoidant and negative coping were negatively associated with energy-vitality, psychological well-being and body image for avoidant coping, and body image and relationships with medical staff for negative coping. CONCLUSIONS: The quality of life of haemodialysis adolescents, and mainly the dimensions of leisure activities, physical well-being, relationships with friends and energy-vitality, were significantly altered compared to that of the French population. The impact of coping strategies on quality of life seems to be important. Given the importance of quality of life and coping strategies in adolescents with chronic disease, health care professionals should integrate these aspects into care management

Using classification and regression tree modelling to investigate response shift patterns in dentine hypersensitivity

BACKGROUND: Dentine hypersensitivity (DH) affects people's quality of life (QoL). However changes in the internal meaning of QoL, known as Response shift (RS) may undermine longitudinal assessment of QoL. This study aimed to describe patterns of RS in people with DH using Classification and Regression Trees (CRT) and to explore the convergent validity of CRT with the then-test and ideals approaches. METHODS: Data from an 8-week clinical trial of mouthwashes for dentine hypersensitivity (n = 75) using the Dentine Hypersensitivity Experience Questionnaire (DHEQ) as the outcome measure, were analysed. CRT was used to examine 8-week changes in DHEQ total score as a dependent variable with clinical status for DH and each DHEQ subscale score (restrictions, coping, social, emotional and identity) as independent variables. Recalibration was inferred when the clinical change was not consistent with the DHEQ change score using a minimally important difference for DHEQ of 22 points. Reprioritization was inferred by changes in the relative importance of each subscale to the model over time. RESULTS: Overall, 50.7% of participants experienced a clinical improvement in their DH after treatment and 22.7% experienced an important improvement in their quality of life. Thirty-six per cent shifted their internal standards downward and 14.7% upwards, suggesting recalibration. Reprioritization occurred over time among the social and emotional impacts of DH. CONCLUSIONS: CRT was a useful method to reveal both, the types and nature of RS in people with a mild health condition and demonstrated convergent validity with design based approaches to detect RS
