Risque augmenté de ré-hospitalisation chez les personnes atteintes de diabète de type 1 et de schizophrénie
2019
Introduction La morbidite et mortalite associees au diabete comme a la schizophrenie suggerent que leur combinaison puisse generer de graves problemes. L’objectif de l’etude etait d’estimer le risque de re-hospitalisation pour complications aigues du diabete et tentative de suicide a trois ans chez des personnes atteintes de diabete et de schizophrenie. Methodes A partir des donnees nationales d’hospitalisation, l’etude en population s’est interessee aux personnes âgees de 15 a 35 ans pour lesquelles une hospitalisation mentionnait un diabete de type 1, entre 2009 et 2012. Pour identifier les personnes atteintes de schizophrenie, un code correspondant a ete recherche pendant ou dans les deu…
Stress, anxiety and depression in heart disease patients: A major challenge for cardiac rehabilitation
2016
International audience; Cardiovascular events and emotional disorders share a common epidemiology, thus suggesting fundamental pathways linking these different diseases. Growing evidence in the literature highlights the influence of psychological determinants in somatic diseases. A patient's socio-economic aspects, personality traits, health behavior and even biological pathways may contribute to the course of cardiovascular disease. Cardiac events often occur suddenly and the episode can be traumatic for people not prepared for such an event. In this review of the literature, the authors tackle the question of psychobiological mechanisms of stress, in a pathophysiological approach to funda…
Personality types in individuals with type 1 and type 2 diabetes
2020
Objective The Type A personality, characterized by impatience, strong career ambition and competitiveness, is associated with greater sensitivity to external stress. Type 1 diabetes (T1D) is an auto-immune disease, which is potentially influenced by stress, unlike type 2 diabetes (T2D). The aim of this study was to assess whether individuals with T1D and T2D exhibited significant differences on the Type A personality scale. We also assessed personality in patients with thyroid auto-immune diseases to validate potential links between auto-immune disease and Type A personality. Design and methods The Bortner questionnaire was used to assess Type A personality in 188 patients with T1D, 430 pa…
Telomeres in the Brain Cortex of Patients with Major Depressive Disorder
2014
Telomeres are complex structures formed by the end of the DNA molecule at the tip of each chromosomal arm. The repeated (TTAGGG) telomeric sequence progressively shortens during lifespan because it cannot be replicated as somatic cells divide, and is highly susceptible to breakage by free radicals. Critically shortened telomeres activate the genetic program of cell senescence and/or apoptosis. The telomere length measured in peripheral blood leucocytes is considered a reliable marker of biological age, mortality risk and exposure to various pathological conditions, including cardiovascular disease, dementia, and metabolic syndrome. Telomere erosion has been observed in psychiatric disorders…
Transcranial Magnetic Stimulation Combined With Nicotine Replacement Therapy for Smoking Cessation: A Randomized Controlled Trial.
2015
Abstract Background Further evidence suggests that repetitive Transcranial Magnetic Stimulation (rTMS) is an effective method to reduce tobacco craving among smokers. Hypothesis As relapse is common within a few days after smoking cessation, we hypothesized that combining the anti-craving effects of rTMS with Nicotine replacement therapy (NRT) to attenuate withdrawal symptoms could increase abstinence rates in smokers with severe nicotine dependence who quit smoking. Methods Thirty-seven smokers who failed to quit with the usual treatments were randomly assigned to two treatment groups to receive either active ( n = 18) or sham ( n = 19) 1-Hz rTMS of the right dorsolateral prefrontal cort…

Activation of a ΔFOSB dependent gene expression pattern in the dorsolateral prefrontal cortex of patients with major depressive disorder
2010
Abstract Background A ΔFOSB mediated transcriptional response in the nucleus accumbens (NAc) is induced by chronic social stress in rodent and a 50% down-regulation of ΔFOSB has been also reported in the NAc of eight depressed subjects. To evaluate the role of ΔFOSB in the prefrontal cortex which is critically involved in negative cognitive bias associated with major depressive disorder (MDD) we have quantified the mRNA levels of ΔFOSB and of five of its major target genes in the Brodmann area 46 from 24 patients with MDD (11 with psychotic symptoms) and 12 controls. Method Expression of the six genes has been quantified by a real-time quantitative PCR method: ΔFOSB , GRIA2 (encoding the Gl…
Fewer Type A personality traits in type 2 diabetes patients with diabetic foot ulcer.
2021
Abstract Aim Type A personality—characterized by time urgency, strong drive, and a need for achievement and competitiveness—has been shown to be associated with reduced mortality in patients with diabetes. However, it is not known whether a Type A personality might protect against diabetic foot ulcer (DFU). This prompted our present analysis of the association between Type A personality and DFU. Methods The Bortner Scale questionnaire was used to assess Type A personality in 386 patients with type 2 diabetes (T2D), including 104 patients also presenting with, and 282 presenting without, DFU. Additional questionnaires were used to assess perceived stress and depression. Results Type A Bortne…
Correlative gene expression pattern linking RNF123 to cellular stress–senescence genes in patients with depressive disorder: Implication of DRD1 in t…
2013
Abstract Background The expression level of the RNF1213 gene in blood cells has been identified as a disease risk marker, more than ten years before the diagnosis of depression ( Glahn et al., 2012 ). To explore the status of this gene in the acute depressive state we have quantified the expression of RNF123 in the blood leukocytes ( N =17), dorsolateral prefrontal and cingulate cortex ( N =24) of patients with diagnosed depression and of matched controls. We have measured the expression of the DRD1 gene as a “neuronal probe”. We have also quantified the mRNA of six genes previously identified as markers of the biopsychological stress associated with major depression: FOS, DUSP1, OGG1, STMN…
Interest of targeting either cortical area Brodmann 9 or 46 in rTMS treatment for depression: a preliminary randomized study.
2013
Abstract Objective To assess the interest of specifically targeting Brodmann Areas (BA) 9 or 46 for rTMS treatment of depression. Methods Patients with Treatment-Resistant Depression were randomly assigned to two treatment groups to receive either rTMS on BA 9 or on BA 46. Each patient underwent 10 sessions of 1Hz-rTMS for 2weeks. The Hamilton and Montgomery–Asberg Depression Rating Scales (HDRS, MADRS) were used under blind conditions to assess the therapeutic response (50% improvement). A Wilcoxon signed-rank test was used to compare the depression rating scales scores obtained before and after the 10 rTMS sessions for each of the two groups. The therapeutic results in the two groups were…

Impact biopsychosocial de la charge des aidants : pourquoi faut-il porter une attention spécifique envers la santé des aidants ?
2018
There are 11 million family caregivers in France and some estimates indicate that there will be 17 million in 2020. Caregiving is a source of chronic stress that requires adaptation and coping strategies. Caregiving may benefit the health of a caregiver with a positive coping style and altruistic goals. However, the caregiver's burden is frequently associated with negative effects in terms of biopsychosocial imbalance and medical conditions, with frequent anxiety and depression. The management of the caregiving burden starts with the recognition of health professionals - caregivers may benefit from consultation-liaison psychiatry and multidisciplinary medico-social strategies, in addition t…
Potential influence of Type A personality on plasma C-reactive protein levels in people with diabetes
2016
IF 4.693; Aim. Type A personality, although classically known as a factor linked to increased vascular risk, has recently been associated with increased survival in patients with diabetes. As low-grade inflammation predicts a poor outcome, the present study explored the potential associations between Type A and plasma levels of C-reactive protein (CRP) in diabetes. Methods. Type A personality was assessed by the Bortner questionnaire in people with diabetes. The association between Type A and plasma CRP levels was examined by multivariable linear regression, and structural equation modelling (SEM) was performed to determine the impact of the major clinical, biological and psychological conf…
Leukocyte telomere length in mastocytosis: correlations with depression and perceived stress.
2013
Abstract Background Mastocytosisis a rare disease associated with chronic symptoms related to mast cell mediator release. Patients with mastocytosis display high level of negative emotionality such as depression and stress sensibility. Brain mast cells are mainly localized in the diencephalon, which is linked to emotion regulatory systems. Negative emotionality has been shown to be associated with telomere shortening. Taken together these observations led us to hypothesize that mast cells activity could be involved in both negative emotionality and telomere shortening in mastocytosis. Objective To demonstrate a possible relationship between negative emotionality in mastocytosis and leukocyt…
