A pregnant adolescent’s vulnerability increases when she is a victim of intrafamilial violence and drug addiction, which cause physical and biopsychosocial damage to the mother and her baby. Objective Present and analyze the case of an adolescent who is addicted to drugs, pregnant and the victim of lifelong intrafamilial violence. Method A case study based on a semi-structured interview conducted in the Obstetrics Emergency Unit at the Teaching Hospital of the University of São Paulo. The data were interpreted and analyzed using Content Analysis. Results intrafamilial violence experienced at the beginning of the adolescent’s early relationships seriously affected her emotional maturity, triggering the development of psychopathologies and leaving her more susceptible to the use and abuse of alcohol and other drugs. The adolescent is repeating her history with her daughter, reproducing the cycle of violence. Conclusion Adolescent pregnancy combined with intrafamilial violence and drug addiction and multiplies the adolescent’s psychosocial vulnerability increased the adolescent’s vulnerability.

OBJECTIVE To investigate the effectiveness of aromatherapy massage using the essential oils (0.5%) of Lavandula angustifolia and Pelargonium graveolens for anxiety reduction in patients with personality disorders during psychiatric hospitalization. METHOD Uncontrolled clinical trial with 50 subjects submitted to six massages with aromatherapy, performed on alternate days, on the cervical and the posterior thoracic regions. Vital data (heart and respiratory rate) were collected before and after each session and an anxiety scale (Trait Anxiety Inventory-State) was applied at the beginning and end of the intervention. The results were statistically analyzed with the chi square test and paired t test. RESULTS There was a statistically significant decrease (p < 0.001) of the heart and respiratory mean rates after each intervention session, as well as in the inventory score. CONCLUSION Aromatherapy has demonstrated effectiveness in anxiety relief, considering the decrease of heart and respiratory rates in patients diagnosed with personality disorders during psychiatric hospitalization.

OBJECTIVE Identifying the violence suffered by the health team workers and their association with Burnout and minor psychiatric disorders. METHODS Cross-sectional study with 269 health team professionals of a public hospital in southern Brazil. Data were collected through the use of the Survey Questionnaire: Workplace Violence in the Health Sector, Maslach Inventory Burnout and Self-Report Questionnaire. RESULTS Workplace violence struck 63.2% of workers, prevailing mostly in women (p = 0.001), among nursing auxiliaries/technicians (p=0.014) and was associated with minor psychiatric disorders (p<0.05), as exposure to different forms of violence increased the chances of these disorders by 60% (CI 95%: 1.2-2.1). The three Burnout dimensions were also associated to violence at work (p<0.05). CONCLUSION Health workers experience violence in the workplace and this exposure is associated with Burnout symptoms and minor psychiatric disorders.

RESUME: L'objectif de cette étude était de déterminer l'impact de la grossesse non compliquée sur l'onde de pouls de la pression aortique centrale. Méthode 66 femmes au total avec une grossesse simple ont été réparties en trois groupes selon le stade de leur gestation: premier trimestre (T1, n=22), deuxième trimestre (T2, n=20) et troisième trimestre (T3, n=24). Le groupe contrôle (C, n=21) était constitué de femmes non enceintes, en bonne santé habituelle, prenant une contraception oestroprogestative. La tonométrie d'aplanation a été utilisée pour l'acquisition des ondes de pouls centrale un appareil disponible dans le commerce (SphygmoCor) permet l'enregistrement de l'onde de pouls périphérique avec un tonomètre d'aplanation de l'artère radiale au niveau du poignet, puis effectue sa transformation en sa forme centrale, grâce à une analyse de Fourrier et une fonction de transfert. L'influence des ondes réfléchies sur l'onde de pouls a été déterminée non seulement pendant la systole (augmentation systolique), comme on procède habituellement dans l'analyse de l'onde de pouls, mais aussi pendant la diastole (augmentation diastolique). Résultats Au cours de la grossesse, les pressions centrales systolique et diastolique sont restées inchangées et comparables aux valeurs mesurées chez les femmes qui ne sont pas enceintes. Dans le groupe contrôle, l'augmentation systolique s'élevait à 8.1±7.5% de la pression de pouls ; il n'y avait pas de différence statistiquement significative avec les valeurs obtenues chez les femmes enceintes, et ce, à n'importe quel stade de la grossesse (T1 : 4.6±11.4%, T2: 5.0±9.3%, T3 : 4.7±8.1%). Par contre, l'amplitude de l'augmentation diastolique diminuait avec la progression de la grossesse (C 6.5±2.4%, T1 : 5.2±3.1%, T2 : 3.8±2.6%; P=0.002 versus C; T3 : 2.3±2.0%; P<0.0001 versus C et P=0.004 versus T 1). Conclusion La grossesse ne modifie pas la forme de l'onde de pouls systolique centrale, ce qui implique de la part du système cardiovasculaire une adaptation fine à la demande croissante de flux sanguin, et ce, à tous les stades de la grossesse. Par contre, l'amplitude de l'onde de réflexion atteignant l'aorte pendant la diastole diminue progressivement au cours de la grossesse. Perspectives De récentes études montrent qu'une valeur anormalement haute de l'augmentation systolique de la pression centrale, comme on peut la déterminer avec la tonométrie d'aplanation, pourrait être un indice de trouble hypertensif de la grossesse débutant. Cette technique simple pourrait être d'autant plus facile à mettre en oeuvre si les valeurs normales pour l'augmentation systolique étaient indépendantes du stade de la grossesse, comme le suggèrent nos résultats, du moins pour les mesures prises en position assise.

Autism spectrum disorders (ASDs) are a heterogeneous group of disorders with a complex genetic etiology. We used high-resolution whole genome array-based comparative genomic hybridization (array-CGH) to screen 223 ASD patients for gene dose alterations associated with susceptibility for autism. Clinically significant copy number variations (CNVs) were identified in 18 individuals (8%), of which 9 cases (4%) had de novo aberrations. In addition, 20 individuals (9%) were shown to have CNVs of unclear clinical relevance. Among these, 13 cases carried rare but inherited CNVs that may increase the risk for developing ASDs, while parental samples were unavailable in the remaining seven cases. Classification of all patients into different phenotypic and inheritance pattern groups indicated the presence of different CNV patterns in different patient groups. Clinically relevant CNVs were more common in syndromic cases compared to non-syndromic cases. Rare inherited CNVs were present in a higher proportion of ASD cases having first- or second-degree relatives with an ASD-related neuropsychiatric phenotype in comparison with cases without reported heredity (P = 0.0096). We conclude that rare CNVs, encompassing potential candidate regions for ASDs, increase the susceptibility for the development of ASDs and related neuropsychiatric disorders giving us further insight into the complex genetics underlying ASDs.

Firstly discovered in rete testis fluid, clusterin is a glycoprotein present in most of the other biological fluids. Several isoforms of clusterin are encoded from a single gene located on chromosome 8 in human species. Among the different isoforms, the secreted form of clusterin is expressed by a variety of tissues, including the nervous system under normal conditions. This form is presumed to play an anti-apoptotic role and seems to be a major determinant in cell survival and neuroplasticity after stroke. In animal models of this pathology, both neuronal and astroglial subpopulations express high levels of clusterin early after the ischemic damage. Recent lines of evidence point also to its possible involvement in neurodegenerative disorders. It is thought that in Alzheimer's disease the association between amyloidogenic peptides and clusterin contributes to limit Aβ species misfolding and facilitates their clearance from the extracellular space. Thus, intercellular and intracellular factors that modulate local clusterin expression in the nervous system may represent potent targets for neurodegenerative disease therapies. In this review we provide a critical overview of the most recent data on the involvement of clusterin in neurodegenerative diseases with special reference to their putative clinical relevance.

The aim of this study was to assess the expectations of adolescents with chronic disorders with regard to transition from pediatric to adult health care and to compare them with the expectations of their parents. A cross-sectional study was carried out including 283 adolescents with chronic disorders, aged 14-25 years (median age, 16.0 years), and not yet transferred to adult health care, and their 318 parents from two university children's hospitals. The majority of adolescents and parents (64%/70%) perceived the ages of 18-19 years and older as the best time to transfer to adult health care. Chronological age and feeling too old to see a pediatrician were reported as the most important decision factors for the transfer while the severity of the disease was not considered important. The most relevant barriers were feeling at ease with the pediatrician (45%/38%), anxiety (20%/24%), and lack of information about the adult specialist and health care (18%/27%). Of the 51% of adolescents with whom the pediatric specialist had spoken about the transfer, 53% of adolescents and 69% of parents preferred a joint transfer meeting with the pediatric and adult specialist, and 24% of these adolescents declared that their health professional had offered this option. In summary, the age preference for adolescents with chronic disorders and their parents to transfer to adult health care was higher than the upper age limits for admission to pediatric health care in many European countries. Anxiety and a lack of information of both adolescents and their parents were among the most important barriers for a smooth and timely transfer according to adolescents and parents.

Background: The objective of this study was to determine if mental health and substance use diagnoses were equally detected in frequent users (FUs) compared to infrequent users (IUs) of emergency departments (EDs). Methods: In a sample of 399 adult patients (>= 18 years old) admitted to a teaching hospital ED, we compared the mental health and substance use disorders diagnoses established clinically and consigned in the medical files by the ED physicians to data obtained in face-to-face research interviews using the Primary Care Evaluation of Mental Disorders (PRIME-MD) and the Alcohol, Smoking and Involvement Screening Test (ASSIST). Between November 2009 and June 2010, 226 FUs (>4 visits within a year) who attended the ED were included, and 173 IUs (<= 4 visits within a year) were randomly selected from a pool of identified patients to comprise the comparison group. Results: For mental health disorders identified by the PRIME-MD, FUs were more likely than IUs to have an anxiety (34 vs. 16%, Chi2(1) = 16.74, p <0.001), depressive (47 vs. 25%, Chi2(1) = 19.11, p <0.001) or posttraumatic stress (PTSD) disorder (11 vs. 5%, Chi2(1) = 4.87, p = 0.027). Only 3/76 FUs (4%) with an anxiety disorder, 16/104 FUs (15%) with a depressive disorder and none of the 24 FUs with PTSD were detected by the ED medical staff. None of the 27 IUs with an anxiety disorder, 6/43 IUs (14%) with a depressive disorder and none of the 8 IUs with PTSD were detected. For substance use disorders identified by the ASSIST, FUs were more at risk than IUs for alcohol (24 vs. 7%, Chi2(1) = 21.12, p <0.001) and drug abuse/dependence (36 vs. 25%, Chi2(1) = 5.52, p = 0.019). Of the FUs, 14/54 (26%) using alcohol and 8/81 (10%) using drugs were detected by the ED physicians. Of the IUs, 5/12 (41%) using alcohol and none of the 43 using drugs were detected. Overall, there was no significant difference in the rate of detection of mental health and substance use disorders between FUs and IUs (Fisher's Exact Test: anxiety, p = 0.567; depression, p = 1.000; PTSD, p = 1.000; alcohol, p = 0.517; and drugs, p = 0.053). Conclusions: While the prevalence of mental health and substance use disorders was higher among FUs, the rates of detection were not significantly different for FUs vs. IUs. However, it may be that drug disorders among FUs were more likely to be detected.

Cannabis use among adolescents and young adults has become a major public health challenge. Several European countries are currently developing short screening instruments to identify 'problematic' forms of cannabis use in general population surveys. One such instrument is the Cannabis Use Disorders Identification Test (CUDIT), a 10-item questionnaire based on the Alcohol Use Disorders Identification Test. Previous research found that some CUDIT items did not perform well psychometrically. In the interests of improving the psychometric properties of the CUDIT, this study replaces the poorly performing items with new items that specifically address cannabis use. Analyses are based on a sub-sample of 558 recent cannabis users from a representative population sample of 5722 individuals (aged 13-32) who were surveyed in the 2007 Swiss Cannabis Monitoring Study. Four new items were added to the original CUDIT. Psychometric properties of all 14 items, as well as the dimensionality of the supplemented CUDIT were then examined using Item Response Theory. Results indicate the unidimensionality of CUDIT and an improvement in its psychometric performance when three original items (usual hours being stoned; injuries; guilt) are replaced by new ones (motives for using cannabis; missing out leisure time activities; difficulties at work/school). However, improvements were limited to cannabis users with a high problem score. For epidemiological purposes, any further revision of CUDIT should therefore include a greater number of 'easier' items.

A large body of published work shows that proton (hydrogen 1 [(1)H]) magnetic resonance (MR) spectroscopy has evolved from a research tool into a clinical neuroimaging modality. Herein, the authors present a summary of brain disorders in which MR spectroscopy has an impact on patient management, together with a critical consideration of common data acquisition and processing procedures. The article documents the impact of (1)H MR spectroscopy in the clinical evaluation of disorders of the central nervous system. The clinical usefulness of (1)H MR spectroscopy has been established for brain neoplasms, neonatal and pediatric disorders (hypoxia-ischemia, inherited metabolic diseases, and traumatic brain injury), demyelinating disorders, and infectious brain lesions. The growing list of disorders for which (1)H MR spectroscopy may contribute to patient management extends to neurodegenerative diseases, epilepsy, and stroke. To facilitate expanded clinical acceptance and standardization of MR spectroscopy methodology, guidelines are provided for data acquisition and analysis, quality assessment, and interpretation. Finally, the authors offer recommendations to expedite the use of robust MR spectroscopy methodology in the clinical setting, including incorporation of technical advances on clinical units. © RSNA, 2014 Online supplemental material is available for this article.

Alcohol consumption during pregnancy causes a major risk of Fetal Alcohol Syndrome (FAS). This article defines the three syndromes linked to alcohol consumption during pregnancy: (1) FAS, with or without confirmed maternal alcohol exposure; (2) alcohol-related birth defect (ARBD) (3) and alcohol-related neurodevelopmental disorder (ARND). The article also reviews data on alcohol use in pregnant women and in women of child-bearing age. The literature indicates that between 6% and 45% pregnant women have an at-risk alcohol use, and suggests that brief counseling interventions designed to prevent at-risk alcohol use are effective. Studies assessing alcohol use and brief intervention efficacy in pregnant women in Switzerland are needed.

BACKGROUND: Healthcare professionals regularly read the summary of product characteristics (SmPC) as one of the various sources of information on the risks of drug use in women of childbearing age and during pregnancy. The aim of this article is to present an overview of the teratogenic potential of various antiepileptic drugs and to compare these data with the information provided by the SmPCs. METHODS: A literature search on the teratogenic risks of 19 antiepileptic agents was conducted and the results were compared with the information on the use in women of childbearing age and during pregnancy provided by the SmPCs of 38 commercial products available in Switzerland and Germany. RESULTS: The teratogenic risk is discussed in all available SmPCs. Quantification of the risk for birth defects and the numbers of documented pregnancies are mostly missing. Reproductive safety information in SmPCs showed poor concordance with risk levels reported in the literature. Recommendations concerning the need to monitor plasma levels and possibly perform dose adjustments during pregnancy to prevent treatment failure were missing in five Swiss and two German SmPCs. DISCUSSION: The information regarding use in women of childbearing age and during pregnancy provided by the SmPCs is heterogeneous and poorly reflects the current state of knowledge. Regular updates of SmPCs are warranted in order for these documents to be of reliable use for health care professionals.

Summary Mood disorders are among the most prevalent, psychosocial^ debilitating, chronic and relapsing forms of psychiatric illnesses. Despite considerable advances in their characterization, the heterogeneous nature of susceptibility factors and patient's symptoms could account for the lack of totally effective and remissive treatment. The neurobiological hypothesis of mood disorders etiology has evolved since the monoamine and neurotrophin theories and current evidence is pointing toward their integration in a broader polygenic epistatic model resulting in defective neuroplasticity of circuitries involved in emotion processing. Consequently, the unraveling of molecular underpinning pathways involved in neuronal plasticity, commonly altered among mood disorder syndromes and symptoms, should shed light on their etiology and provide new drug target. The transcription factor CREB has been critically involved in the long-lasting forms of neuronal plasticity and in the regulation of several mood disorders susceptibility genes. In addition, altered CREB activity has been associated with mood disorders pathophysiology and pharmacotherapy. Interestingly, the newly-identified protein CREB-regulated transcription coactivator 1 (CRTC1) was shown by previous studies in the laboratory to be a neuroactivity- dependent cAMP and calcium sensor, a potent activator of CREB-dependent transcription and involved in neuroplasticity mechanisms associated with long-term synaptic potentiation. Furthermore, the major mood disorder susceptibility gene Bdnf was suggested to be transcriptional regulated by CRTC1. Therefore, we aimed to investigate a role for CRTC1 in mood disorders by generating and characterizing a Crtcl deficient mouse model at the behavioral and molecular levels. Interestingly, their comprehensive characterization revealed a behavioral profile mirroring several major symptoms comorbid in mood disorders, including altered social interactions, aggressive behaviors, obesity, psychomotor retardation, increased emotional response to stress, decreased sexual drive and depression-like behaviors. To investigate the molecular mechanisms underlying these pathological behaviors and the implication of CRTC1 in the regulation of CREB-regulated genes in vivo, we also quantified transcript levels of several relevant CREB-regulated susceptibility genes in brain structures involved in the pathophysiology of mood disorders. Strikingly, we found the underexpression of primary components of the neurotrophin system: Bdnf and its cognate receptor TrkB, a marked decrease in the Nr4a family of transcription factors, implicated in neuroplasticity and associated with dopamine-related disorders, as well as in several other relevant CREB regulated genes. Moreover, neurochemical analysis revealed that Crtcl null mice presented alteration in prefrontal cortical monoamine turnover as well as in hippocampal and accumbal serotonin levels, similarly associated with mood disorders etiology and pharmacotherapy. Together, the present thesis supports the involvement of CRTC1 pathway hypofunction in the pathogenesis of mood disorders and specifically in pathological aggression, obesity and depression-related behavior comorbidities. Ultimately, CRTC1 may represent an interesting antidepressant, antiaggressive or mood stabilizer drug target candidate through the modulation of major CREB regulated susceptibility genes. Les troubles de l'humeur comptent parmi les maladies psychiatriques les plus prévalentes, psychosocialement débilitantes, chroniques et avec le plus grand risque de rechute. Malgré de considérable avancées dans leur caractérisation, la nature hétérogène des facteurs de susceptibilité et des symptômes présentés par les patients, semble justifier l'absence de traitement entraînant une rémission complète de la maladie. L'hypothèse de l'étiologie neurobiologique des troubles de l'humeur a évolué depuis la théorie des monoamines et des neurotrophines. Actuellement, elle tend à les englober dans un modèle polygénique épistatique induisant une déficience de la neuroplasticité des circuits impliqué dans la régulation des émotions. Par conséquent, il apparaît particulièrement relevant de caractériser des voies moléculaires impliquées dans la plasticité neuronale, communément altérées parmi les différents syndromes et symptômes des maladies de l'humeur, afin d'améliorer leur compréhension ainsi que de proposer de nouvelles cibles thérapeutiques potentielles. Le facteur de transcription CREB a été de façon répétée et cohérente impliqué dans les mécanismes à long terme de la plasticité neuronale, ainsi que dans la régulation de plusieurs gènes de susceptibilité aux maladies de l'humeur. De plus, une altération dans l'activité de CREB a été impliqué dans leur étiologie et pharmacothérapie. De façon intéressante, des résultats préliminaires sur la protéine récemment découverte CREB-regulated transcription coactivator 1 (CRTC1) ont indiqué que son activation était dépendante de l'activité neuronale, qu'il était un senseur du calcium et de l'AMPc, ainsi qu'un coactivateur de CREB requis et puissant impliqué dans les mécanismes de plasticité neuronale associés à la potentialisation à long terme. En outre, des résultats ont suggéré que le gène majeur de susceptibilité Bdnf est régulé par CRTC1. Ainsi, notre objectif a été d'investiguer un rôle éventuel de CRTC1 dans les maladies de l'humeur en générant et caractérisant une lignée de souris déficiente pour Crtcl, tant au niveau comportemental que moléculaire. De façon intéressante, leur caractérisation détaillée a révélé un profil comportemental reflétant de nombreux aspects des maladies de l'humeur incluant une altération des interactions sociales, une agression pathologique, l'obésité, un retard psychomoteur, une réponse émotionnelle au stress accrue, une diminution de la motivation sexuelle, et des comportements reliés à la dépression. Afin d'investiguer les mécanismes moléculaires sous- jacents cette altération du comportement, ainsi que l'implication de CRTC1 dans l'expression des gènes régulés par CREB in vivo, nous avons quantifié les niveaux de transcrits de plusieurs gènes de susceptibilité régulés par CREB et impliqués dans la physiopathologie des maladies de l'humeur. Remarquablement, nous avons trouvé la sous-expression de composants primordiaux du système neurotrophique: Bdnf et son récepteur TrkB, une diminution majeure de la famille des facteurs de transcription Nr4a, impliqués dans la neuroplasticité et associés à des désordres liés à la dopamine, ainsi que de nombreux autres gènes relevants régulés par CREB. De plus, une analyse neurochimique a révélé que les souris déficientes pour Crtcî présentent une altération du turn-over des monoamines du cortex préfrontal ainsi que des niveaux hippocampaux et accumbaux de sérotonine, associés de façon similaire dans l'étiologie et la pharmacothérapie des maladies de l'humeur. Vue dans son ensemble, la présente thèse supporte l'implication d'une sous-régulation de la voie de CRTCI dans la pathogenèse des maladies de l'humeur ainsi que dans la comorbidité de l'agression pathologique, l'obésité et la dépression. En conclusion, CRTCI pourrait représenter une cible médicamenteuse intéressante aux propriétés antidépressante, antiagressive ou stabilisatrice de l'humeur au travers de la modulation de gènes de susceptibilité majeurs régulés par CREB.

Clinical experience suggests that longstanding personality characteristics as a person's most distinctive features of all are likely to play a role in how someone with dementia copes with his increasing deficiencies. Personality characteristics may have a pathoplastic effect on both behavioral and psychological symptoms (BPS) or on cognition as well as cognitive decline. Cognitive disorders accompanied by BPS are a tremendous burden for both the patient and their proxies. This review suggests that premorbid personality characteristics are co-determinants of BPS in cognitive disorders, but much effort is needed to clarify whether or not specific premorbid personality traits are associated with specific BPS as no strong links have so far emerged. This review further shows that a growing field of research is interested in the links not only between quite short-lived emotional states and cognitive processes, but also between longstanding personality traits and cognition in both healthy individuals and patients with neurodegenerative disorders. Furthermore, a few studies found that specific premorbid personality traits may be risk factors for neurodegenerative diseases. However, research findings in this area remain scarce despite a huge literature on personality and cognitive disorders in general. An important shortcoming that hampers so far the progress of our understanding in these domains is the confusion in the literature between longstanding premorbid personality traits and transient personality changes observed in neurodegenerative diseases. Few studies have based their assessments on accepted personality theories and carefully investigated premorbid personality traits in patients with cognitive disorders, although assessing personality may be complicated in these patients. Studying the impact of personality characteristics in cognitive disorders is an especially promising field of research in particular when concomitantly using neurobiological approaches, in particular structural brain imaging and genetic studies as suggested by as yet rare studies. Improved understanding of premorbid personality characteristics as determinants of both BPS or cognitive capacities or decline is likely to influence our attitudes towards the treatment of demented patients and ultimately to help in alleviating a patient's and their proxies' burden.
