Recouvrement regarding Bloch wavefunctions involving holes within a semiconductor.
Mucosal surfaces are a unique symbiotic environment between a host and a vast and diverse ecology of microbes. These microbes have great immunomodulatory potential with respect to the host organism. Indeed, the mucosal immune system strikes a delicate balance between tolerance of commensal organisms and overt inflammation to ward off pathogens. Disruptions of the microbial ecology at mucosal surfaces has been described in a vast number of different human disease processes including many forms of arthritis, and the resulting implications are still being understood to their fullest. Herein, we review the current state of knowledge in microbe-host interactions as it relates to the development of arthritis through bacterial translocation, bacterial metabolite production, education of the immune response, and molecular mimicry. OBJECTIVES Speed of thought is a central phenomenon in mood disorders. We aimed to provide an update on the topic ten years after a first narrative review published on racing and crowded thoughts in mood disorders. This update is based on recent publications, including recent works of our group. METHODS Narrative review based on publications from the last ten years including publications of our group and a systematic research of references on PubMed. RESULTS The traditional dichotomist view of racing versus crowded thoughts is not refuted but appears to be more complex, as revealed by validation studies of the Racing and Crowded Thoughts Questionnaire. Moreover, this dualistic view can no longer be conceptualized in a simple bijective concordance with the distinction of hypomania versus mixed depression. We also show that racing/crowded thoughts are strongly associated with mixed depression and not with non-mixed depression, that they tend to be more associated in hypomania to irritability than to the typical symptoms of energy and activity increase and that they are clearly distinguishable from ruminations. Yet, although tightly linked to mood disorders, racing/crowded thoughts appear to be associated to anxiety as well as attention deficit/hyperactivity disorder and insomnia. CONCLUSIONS Racing and crowded thoughts should be studied in a dimensional perspective as an important facet of mind activity within and beyond the field of mood disorders. INTRODUCTION All plastic surgeons are frequently faced with patients with Body Dysmorphic Disorder (BDD). However, no screening test exists in French to help the plastic surgeons to diagnose this disease. The Body Dysmorphic Disorder Questionnaire (BDDQ) is the Gold Standard to easily detect BDD in consultation with any non-psychiatric physician. The aim of this study was to translate and validate the BDDQ into French to help plastic surgeons to detect BDD before the surgery. This way, plastic surgeons will be able to provide an optimal medical care and to reduce the risk of psychiatric collapse. METHODS We asked Katherine Philipps for her approval to use her BDDQ for our study, and thereafter we translated it respecting the criteria of the World Health Organization. We first evaluated the psychometric qualities of the BDDQ in French and then its reproducibility and its sensitivity to change. RESULTS A French version of the BDDQ appeared to be reliable and comprehensible. The questionnaire has been tested on a sample of patients in plastic surgery consultation, at a T moment and a T plus one month to certify its reproducibility and its sensitivity to change. CONCLUSION These results permit to claim that the French version of the BDDQ is now validated to detect patients with a BDD in a plastic surgery consultation. BACKGROUND Although psychopathy and its predictive factors are well documented in clinical samples, studies in non-clinical populations are relatively rare. We proposed to assess psychopathy traits in a population of Tunisian university students and to analyze their predictive factors. METHOD This was a cross-sectional study of 516 university students enrolled at three major Tunisian universities (Faculty of Humanities and Social Sciences of Tunis, National Engineering School of Tunis, Faculty of Medicine of Tunis). Participants responded to a survey sheet containing sociodemographic data and the Levenson Self-Report Psychopathy Scale. RESULTS The students were female in 63.2 % of the cases, with a mean age of 22.7years. https://www.selleckchem.com/products/Staurosporine.html The socio-economic level was middle class in 62.4% of the cases. More than one-quarter of students (26.7%) consumed tobacco. The majority of students (81.4%) spent their free time on the Internet, while 11.8% participated in associative work. Psychopathy scores were relatively high (mean LSRPS scores=64.8) with no noticeable gender differences. Psychopathic traits were significantly associated with university (P=0.017), maternal occupational status (P=0.038), and tobacco use (P=0.029). In addition, the total psychopathy score was significantly lower among students sharing activities with their families (P=0.044) and among students participating in associational work (P=0.025). The multivariate multiple regression has retained as predictive factors of psychopathic traits the fact of being the eldest of his siblings and the associative work. CONCLUSION Prevention strategies should be put in place to prevent psychopathy and its individual and social impacts in young adults in general, and in university students in particular, especially promoting associative activity in the university environment which is currently lacking in our context. The exposure in cognitive behavioral therapy (CBT) is a well-known intervention, widely investigated in scientific research. Several studies have shown the benefits of this intervention in the treatment of anxiety disorders, obsessive-compulsive disorders (OCD) and post-traumatic stress disorders (PTSD). The different exposure techniques are mainly based on the emotional processing of fear theory and use an emotional stimulation of fear, following by its habituation. However, new approaches have emerged and are based on the inhibitory learning theory. The virtual reality technology allows emotional involvement from patients and represents a complementary approach to the classical modalities of exposure therapy (e.g., mental or in vivo expositions). This modern approach presents specific features that need to be taken into account by the therapist. Firstly, the presence feeling, which is defined as the "be there" feeling. This feeling is dependent on immersive technical features and personality factors. Second (e.g., the presence feeling); and 4) a massive use of waiting lists as a control measure. Despite these limitations, the VRET have strong silver linings 1) the easy access to exposure (less limited than standard exposure techniques) and a cost reduction; 2) highly guaranteed security; 3) the anonymization of exposures (i.e., the patients do not risk meeting someone they know during the exposure therapy); 4) the therapist has a greater control of exposures; 5) a standardization of the exposures; 6) a greater involvement in therapy for technophile patients. Virtual exposure also seems to be generally more accepted by patients. CONTEXT Electro-convulsive therapy (ECT) is the most effective treatment for treatment resistant mood disorders and catatonia. ECT also appears to be an effective treatment in combination with clozapine in the context of treatment resistant schizophrenia spectrum disorders. Although increasingly codified (guidelines on indications, contraindications, methods of implementation), the practice of ECT still lacks consensual protocols. The concomitant use of psychotropic and/or non-psychotropic medication is a common situation when ECT treatment is considered. To our knowledge, there is to date no summary of studies or case reports in France, nor any proposal for guidelines concerning the management of medication of the patient to whom ECT sessions are offered. Indeed, several particularities must be considered. This article proposes to specify for each pharmacological class the possible interaction between ECT and medication. A first section of this article will be devoted to non-psychotropic treatments, and a seed pharmacological treatments. The prescription for each molecule should be reviewed when ECT treatment is initiated. BACKGROUND Food Craving (FC) is a construct influenced by cognitive, emotional, physiological and external components, severely altered in Eating Disorders (EDs). OBJECTIVES To investigate how FC was measured in EDs. METHODS A search was conducted (PubMed, Scopus and PsycINFO databases) for studies that have investigated FC in EDs published in the last thirty years. RESULTS The studies found (n=37) demonstrated that FC is a predictor of binge eating in individuals with Bulimia Nervosa and Binge Eating Disorder, which are more sensitive to the environment and emotional factors, whereas, in individuals with Anorexia Nervosa, FC levels are lower. DISCUSSION FC is a physiological component of eating behavior, as well as the craving/urge that arises associated with thirst during dehydration, and food restriction is a crucial mechanism for the restriction-binge cycle to hold. Further studies are needed to see if FC increases in response to treatment for Anorexia Nervosa, recognizing that individuals without Anorexia Nervosa have higher FC levels and greater motivational orientation towards food. CONCLUSIONS It is necessary to understand the physiological role of FC and also consider the significance of each food in an individual eating context (eating attitudes) and whether it is treated like a "drug" or just as a desired tasty food and future studies should verify possible neural changes involved in FC after nutritional treatment. INTRODUCTION The Sexual Addiction Screening Test (SAST) is one of the most frequently used tools on the international level for assessing sexual addiction. This study aimed to translate the English version of the SAST, and adapt and test the psychometric properties of its French version (the SAST-Fr) by establishing its factor structure, internal consistency and convergent validity. METHODS Three hundred ninety eight voluntary participants were recruited online through specialized forums. Participants completed a sociodemographic questionnaire, the SAST-Fr and the diagnostic criteria of sexual addiction proposed by Goodman. We tested the psychometric properties of SAST-Fr through an exploratory factorial analysis, especially its internal consistency, using the Kuder-Richardson alpha (KR-20) given that the items were dichotomous. We also performed correlation analyses of Bravais-Pearson on numerical variables. Finally, we studied the predictive validity of Goodman's score in predicting SAST-Fr criteria using a ROC (Receiver Operating Characteristics) analysis. RESULTS Mean age of participants was 29.08 years (±11.30) and included 54% of women (n=215). Statistical analysis had shown that SAST-Fr had a one-factor structure explaining 31% of the variance, an excellent internal consistency (KR-20=0.90). We found significant correlation between SAST-Fr item scores and PEACCE scores (r=0.87; P less then 0.001) and Goodman's criteria (r=0.79; P less then 0.001). CONCLUSION Our results indicate that the psychometric properties of the French version of the SAST are comparable to its original English version with a one-factor structure. The SAST-Fr is a reliable and valid questionnaire to assess symptoms of sexual addiction.
