Physical activity in schizophrenia is higher in the first episode than in subsequent ones

Schizophrenia is frequently associated with abnormal motor behavior, particularly hypokinesia. The course of the illness tends to deteriorate in the first years. We aimed to assess gross motor activity in patients with a first episode (n = 33) and multiple episodes (n = 115) of schizophrenia spectrum disorders using wrist actigraphy. First episode patients were younger, had higher motor activity and reduced negative symptom severity. Covarying for age, chlorpromazine equivalents, and negative symptoms, first episode patients still had higher motor activity. This was also true after excluding patients with schizophreniform disorder from the analyses. In first episode patients, but not in patients with multiple episodes, motor activity was correlated with antipsychotic dosage. In conclusion, after controlling for variables related to disorder chronicity, patients with first episodes were still more active than patients with multiple episodes. Thus, reduced motor activity is a marker of deterioration in the course of schizophrenia spectrum disorders.

High-Dose Benzodiazepine Dependence: A Qualitative Study of Patients' Perceptions on Initiation, Reasons for Use, and Obtainment

BACKGROUND High-dose benzodiazepine (BZD) dependence is associated with a wide variety of negative health consequences. Affected individuals are reported to suffer from severe mental disorders and are often unable to achieve long-term abstinence via recommended discontinuation strategies. Although it is increasingly understood that treatment interventions should take subjective experiences and beliefs into account, the perceptions of this group of individuals remain under-investigated. METHODS We conducted an exploratory qualitative study with 41 adult subjects meeting criteria for (high-dose) BZD-dependence, as defined by ICD-10. One-on-one in-depth interviews allowed for an exploration of this group's views on the reasons behind their initial and then continued use of BZDs, as well as their procurement strategies. Mayring's qualitative content analysis was used to evaluate our data. RESULTS In this sample, all participants had developed explanatory models for why they began using BZDs. We identified a multitude of reasons that we grouped into four broad categories, as explaining continued BZD use: (1) to cope with symptoms of psychological distress or mental disorder other than substance use, (2) to manage symptoms of physical or psychological discomfort associated with somatic disorder, (3) to alleviate symptoms of substance-related disorders, and (4) for recreational purposes, that is, sensation-seeking and other social reasons. Subjects often considered BZDs less dangerous than other substances and associated their use more often with harm reduction than as recreational. Specific obtainment strategies varied widely: the majority of participants oscillated between legal and illegal methods, often relying on the black market when faced with treatment termination. CONCLUSIONS Irrespective of comorbidity, participants expressed a clear preference for medically related explanatory models for their BZD use. We therefore suggest that clinicians consider patients' motives for long-term, high-dose BZD use when formulating treatment plans for this patient group, especially since it is known that individuals are more compliant with approaches they perceive to be manageable, tolerable, and effective.

Predictors for DSM-5 nonsuicidal self-injury in female adolescent inpatients: The role of childhood maltreatment, alexithymia, and dissociation

The purpose of this study was to examine the relationship between various adverse childhood experiences, alexithymia, and dissociation in predicting nonsuicidal self-injury (NSSI) in an inpatient sample of female adolescents. Seventy-two adolescents (aged 14–18 years) with NSSI disorder (n=46) or mental disorders without NSSI (n=26) completed diagnostic interviews and self-report measures to assess NSSI disorder according to the DSM-5 criteria, childhood maltreatment, alexithymia, and dissociation. Alexithymia and dissociation were highly prevalent in both study groups. Multivariate logistic regression analyses indicated that only alexithymia was a significant predictor for NSSI, whereas childhood maltreatment and dissociation had no predictive influence. The association between alexithymia and NSSI emphasizes the significance of emotion regulation training for female adolescents with NSSI. Efforts to reduce NSSI behavior should therefore foster skills to heighten the perception and recognition of one’s own emotions.

Adjustment Disorders Are Uniquely Suited for eHealth Interventions: Concept and Case Study

Background: Adjustment disorders (also known as mental distress in response to a stressor) are among the most frequently diagnosed mental disorders in psychiatry and clinical psychology worldwide. They are also commonly diagnosed in clients engaging in deliberate self-harm and in those consulting general practitioners. However, their reputation in research-oriented mental health remains weak since they are largely underresearched. This may change when the International Statistical Classification of Diseases-11 (ICD-11) by the World Health Organization is introduced, including a new conceptualization of adjustment disorders as a stress-response disorder with positively defined core symptoms. Objective: This paper provides an overview of evidence-based interventions for adjustment disorders. Methods: We reviewed the new ICD-11 concept of adjustment disorder and discuss the the rationale and case study of an unguided self-help protocol for burglary victims with adjustment disorder, and its possible implementation as an eHealth intervention. Results: Overall, the treatment with the self-help manual reduced symptoms of adjustment disorder, namely preoccupation and failure to adapt, as well as symptoms of depression, anxiety, and stress. Conclusions: E-mental health options are considered uniquely suited for offering early intervention after the experiences of stressful life events that potentially trigger adjustment disorders.

An integrated molecular biology and computational approach to CYP1A1 expression in human brain

The cytochromes P450 comprise a superfamily of heme-containing mono-oxygenases. These enzymes metabolize numerous xenobiotics, but also play a role in metabolism of endogenous compounds. The P450 1A1 enzyme generally metabolizes polycyclic aromatic hydrocarbons, and its expression can be induced by aryl hydrocarbon receptor (AhR) activation. CYP1A1 is an exception to the generality that the majority of CYPs demonstrate highest expression in liver; CYP1Al is present in numerous extrahepatic tissues, including brain. This P450 has been observed in two forms, wildtype (WT) and brain variant (BV), arising from alternatively spliced mRNA transcripts. The CYP1A1 BV mRNA presented an exon deletion and was detected in human brain but not liver tissue of the same individuals. ^ Quantitative PCR analyses were performed to determine CYP1A1 WT and BV transcript expression levels in normal, bipolar disorder or schizophrenic groups. In our samples, we show that CYP1A1 BV mRNA, when present, is found alongside the full-length form. Furthermore, we demonstrate a significant decrease in expression of CYP1A1 in patients with bipolar disorder or schizophrenia. The expression level was not influenced by post-mortem interval, tissue pH, age, tobacco use, or lifetime antipsychotic medication load. ^ There is no indication of increased brain CYP1A1 expression in normal smokers versus non-smokers in these samples. We observed slightly increased CYP1A1 expression only in bipolar and schizophrenic smokers versus non-smokers. This may be indicative of complex interactions between neuronal chemical environments and AhR-mediated CYP1A1 induction in brain. ^ Structural homology modeling demonstrated that P450 1A1 BV has several alterations to positions/orientations of substrate recognition site residues compared to the WT isoform. Automated substrate docking was employed to investigate the potential binding of neurological signaling molecules and neurotropic drugs, as well as to differentiate specificities of the two P450 1A1 isoforms. We consistently observed that the BV isoform produced energetically favorable substrate dockings in orientations not observed for the same substrate in the WT isoform. These results demonstrated that structural differences, namely an expanded substrate access channel and active site, confer greater capacity for unique compound docking positions suggesting a metabolic profile distinct from the wildtype form for these test compounds. ^

Diagnosis and Management of Grain-Induced Asthma

Grain-induced asthma is a frequent occupational allergic disease mainly caused by inhalation of cereal flour or powder. The main professions affected are bakers, confectioners, pastry factory workers, millers, farmers, and cereal handlers. This disorder is usually due to an IgE-mediated allergic response to inhalation of cereal flour proteins. The major causative allergens of grain-related asthma are proteins derived from wheat, rye and barley flour, although baking additives, such as fungal α-amylase are also important. This review deals with the current diagnosis and treatment of grain-induced asthma, emphasizing the role of cereal allergens as molecular tools to enhance diagnosis and management of this disorder. Asthma-like symptoms caused by endotoxin exposure among grain workers are beyond the scope of this review. Progress is being made in the characterization of grain and bakery allergens, particularly cereal-derived allergens, as well as in the standardization of allergy tests. Salt-soluble proteins (albumins plus globulins), particularly members of the α-amylase/trypsin inhibitor family, thioredoxins, peroxidase, lipid transfer protein and other soluble enzymes show the strongest IgE reactivities in wheat flour. In addition, prolamins (not extractable by salt solutions) have also been claimed as potential allergens. However, the large variability of IgE-binding patterns of cereal proteins among patients with grain-induced asthma, together with the great differences in the concentrations of potential allergens observed in commercial cereal extracts used for diagnosis, highlight the necessity to standardize and improve the diagnostic tools. Removal from exposure to the offending agents is the cornerstone of the management of grain-induced asthma. The availability of purified allergens should be very helpful for a more refined diagnosis, and new immunomodulatory treatments, including allergen immunotherapy and biological drugs, should aid in the management of patients with this disorder.

Conductancia del mesófilo en especies forestales: implicaciones en la respuesta fotosintética a la disponibilidad de agua y luz

La fotosíntesis es el proceso biológico que permite la producción primaria y, por tanto, la vida en nuestro planeta. La tasa fotosintética viene determinada por la ‘maquinaria’ bioquímica y las resistencias difusivas al paso del CO2 desde la atmósfera hasta su fijación en el interior de los cloroplastos. Históricamente la mayor resistencia difusiva se ha atribuido al cierre estomático, sin embargo ahora sabemos, debido a las mejoras en las técnicas experimentales, que existe también una resistencia grande que se opone a la difusión del CO2 desde los espacios intercelulares a los lugares de carboxilación. Esta resistencia, llamada normalmente por su inversa: la conductancia del mesófilo (gm), puede ser igual o incluso superior a la resistencia debida por el cierre estomático. En la presente tesis doctoral he caracterizado la limitación que ejerce la resistencia del mesófilo a la fijación de CO2 en diversas especies forestales y en distintos momentos de su ciclo biológico. En la fase de regenerado, hemos estudiado tres situaciones ambientales relevantes en el mayor éxito de su supervivencia, que son: el déficit hídrico, su interacción con la irradiancia y el paso del crecimiento en la sombra a mayor irradiancia, como puede suceder tras la apertura de un hueco en el dosel forestal. En la fase de arbolado adulto se ha caracterizado el estado hídrico y el intercambio gaseoso en hojas desarrolladas a distinta irradiancia dentro del dosel vegetal durante tres años contrastados en pluviometría. Para cada tipo de estudio se han empleado las técnicas ecofisiológicas más pertinentes para evaluar el estado hídrico y el intercambio gaseoso. Por su complejidad y la falta de un método que permita su cuantificación directa, la gm ha sido evaluada por los métodos más usados, que son: la discriminación isotópica del carbono 13, el método de la J variable, el método de la J constante y el método de la curvatura. Los resultados más significativos permiten concluir que la limitación relativa a la fotosíntesis por la conductancia estomática, del mesófilo y bioquímica es dependiente de la localización de la hoja en el dosel forestal. Por primera vez se ha documentado que bajo estrés hídrico las hojas desarrolladas a la sombra estuvieron más limitadas por una reducción en la gm, mientras que las hojas desarrolladas a pleno sol estuvieron más limitadas por reducción mayor de la conductancia estomática (gsw). Encontramos buena conexión entre el aparato fotosintético foliar y el sistema hídrico debido al alto grado de correlación entre la conductancia hidráulica foliar aparente y la concentración de CO2 en los cloroplastos en distintas especies forestales. Además, hemos mostrado diferentes pautas de regulación del intercambio gaseoso según las particularidades ecológicas de las especies estudiadas. Tanto en brinzales crecidos de forma natural y en el arbolado adulto como en plántulas cultivadas en el invernadero la ontogenia afectó a las limitaciones de la fotosíntesis producidas por estrés hídrico, resultando que las limitaciones estomáticas fueron dominantes en hojas más jóvenes mientras que las no estomáticas en hojas más maduras. La puesta en luz supuso un gran descenso en la gm durante los días siguientes a la transferencia, siendo este efecto mayor según el grado de sombreo previo en el que se han desarrollado las hojas. La aclimatación de las hojas a la alta irradiancia estuvo ligada a las modificaciones anatómicas foliares y al estado de desarrollo de la hoja. El ratio entre la gm/gsw determinó la mayor eficiencia en el uso del agua y un menor estado oxidativo durante la fase de estrés hídrico y su posterior rehidratación, lo cual sugiere el uso de este ratio en los programas de mejora genética frente al estrés hídrico. Debido a que la mayoría de modelos de estimación de la producción primaria bruta (GPP) de un ecosistema no incluye la gm, los mismos están incurriendo en una sobreestimación del GPP particularmente bajo condiciones de estrés hídrico, porque más de la mitad de la reducción en fotosíntesis en hojas desarrolladas a la sombra se debe a la reducción en gm. Finalmente se presenta un análisis de la importancia en las estimas de la gm bajo estrés hídrico de la refijación del CO2 emitido en la mitocondria a consecuencia de la fotorrespiración y la respiración mitocondrial en luz. ABSTRACT Photosynthesis is the biological process that supports primary production and, therefore, life on our planet. Rates of photosynthesis are determined by biochemical “machinery” and the diffusive resistance to the transfer of CO2 from the atmosphere to the place of fixation within the chloroplasts. Historically the largest diffusive resistance was attributed to the stomata, although we now know via improvements in experimental techniques that there is also a large resistance from sub-stomatal cavities to sites of carboxylation. This resistance, commonly quantified as mesophyll conductance (gm), can be as large or even larger than that due to stomatal resistance. In the present PhD I have characterized the limitation exerted by the mesophyll resistance to CO2 fixation in different forest species at different stages of their life cycle. In seedlings, we studied three environmental conditions that affect plant fitness, namely, water deficit, the interaction of water deficit with irradiance, and the transfer of plants grown in the shade to higher irradiance as can occur when a gap opens in the forest canopy. At the stage of mature trees we characterized water status and gas exchange in leaves developed at different irradiance within the canopy over the course of three years that had contrasting rainfall. For each study we used the most relevant ecophysiological techniques to quantify water relations and gas exchange. Due to its complexity and the lack of a method that allows direct quantification, gm was estimated by the most commonly used methods which are: carbon isotope discrimination, the J-variable, constant J and the curvature method The most significant results suggest that the relative limitation of photosynthesis by stomata, mesophyll and biochemistry depending on the position of the leaf within the canopy. For the first time it was documented that under water stress shaded leaves were more limited by a reduction in gm, while the sun-adapted leaves were more limited by stomatal conductance (gsw). The connection between leaf photosynthetic apparatus and the hydraulic system was shown by the good correlations found between the apparent leaf hydraulic conductance and the CO2 concentration in the chloroplasts in shade- and sun-adapted leaves of several tree species. In addition, we have revealed different patterns of gas exchange regulation according to the functional ecology of the species studied. In field grown trees and greenhouse-grown seedlings ontogeny affected limitations of photosynthesis due to water stress with stomatal limitations dominating in young leaves and nonstomatal limitations in older leaves. The transfer to high light resulted in major decrease of gm during the days following the transfer and this effect was greater as higher was the shade which leaves were developed. Acclimation to high light was linked to the leaf anatomical changes and the state of leaf development. The ratio between the gm/gsw determined the greater efficiency in water use and reduced the oxidative stress during the water stress and subsequent rehydration, suggesting the use of this ratio in breeding programs aiming to increase avoidance of water stress. Because most models to estimate gross primary production (GPP) of an ecosystem do not include gm, they are incurring an overestimation of GPP particularly under conditions of water stress because more than half of An decrease in shade-developed leaves may be due to reduction in gm. Finally, we present an analysis of the importance of how estimates of gm under water stress are affected by the refixation of CO2 that is emitted from mitochondria via photorespiration and mitochondrial respiration in light.

El sistema SONRIE (Sistema de terapia, basadO en KiNect, paRa nIños con parálisis cErebral), realizado como Proyecto Fin de Grado por Dña. Estefanía Sampedro Sánchez, se desarrolló con el fin de permitir el proceso de rehabilitación de los músculos faciales en niños con Parálisis Cerebral Infantil (PCI). SONRIE se compone de una plataforma de juegos cuyo objetivo es lograr una mejora terapéutica en la musculatura orofacial de niños diagnosticados de PCI con edades comprendidas entre los 4 y los 12 años. El escenario de aplicación del sistema SONRIE son las escuelas de integración que tienen escolarizados alumnos diagnosticados con este trastorno. La posibilidad de rehabilitación de los músculos faciales mediante tratamientos que se apoyan en el uso de sistemas telemáticos, junto con el empleo de tecnologías actuales (Realidad Virtual, Realidad Aumentada y Serious Games) supone una gran innovación en el entorno de la neuro-rehabilitación, entendida como el proceso de terapia que permite optimizar la participación de una persona en la sociedad, alcanzando un grado de bienestar óptimo. El trabajo realizado en este Proyecto Fin de Grado pretende escalar el sistema SONRIE, mediante el análisis, diseño y desarrollo de un Framework encargado de facilitar, ampliar y validar el uso adecuado del sistema SONRIE en entornos escolares a través de la integración de nuevas tecnologías. La plataforma desarrollada en este proyecto, permite dotar de dinamismo y persistencia a la plataforma de juegos, ofreciendo a los usuarios de SONRIE (principalmente fisioterapeutas y rehabilitadores que trabajan en entornos escolares) un sistema de terapia para niños con PCI accesible vía web. En este Proyecto Fin de Grado se describe el conjunto de componentes software desarrollados con el fin de proporcionar un entorno web que escale el sistema SONRIE, convirtiéndolo en un sistema de terapia efectivo, completo y usable. ABSTRACT. The SONRIE system (Sistema de terapia, basadO en KiNect, paRa nIños con parálisis cErebral), performed as a final project by Miss Estefanía Sampedro, was developed in order to allow the rehabilitation process of the facial muscles of children with Cerebral Palsy (CP). SONRIE consists of a gaming platform which aims to achieve a therapeutic improvement in the orofacial musculature on children diagnosed with CP aged between 4 and 12 years. The application scenario of the SONRIE system are the integration schools that have students diagnosed with this disorder. The possibility of rehabilitation of facial muscles through treatments based on the use of telematics systems, together with the use of new technologies (Virtual Reality, Augmented Reality and Serious Games) is a great innovation in the neuro-rehabilitation environment, understood as the therapy process that optimizes the participation of a person in the society, reaching an optimum level of welfare. The work done in this final project aims to scale the SONRIE system, through the analysis, design and development of a framework in charge of facilitating, extending and validating the proper use of the SONRIE system in school environments, through the integration of new technologies. The platform developed in this project, can provide dynamism and persistence to the gaming platform, offering to the SONRIE users (mainly physiotherapists and rehabilitators who work in school settings) a therapy system for children with CP accessible via web. In this final project are described the software components developed in order to provide a web environment that scales the SONRIE system, making it an effective, complete and usable therapy system.

Ablation of P/Q-type Ca2+ channel currents, altered synaptic transmission, and progressive ataxia in mice lacking the α1A-subunit

The Ca2+ channel α1A-subunit is a voltage-gated, pore-forming membrane protein positioned at the intersection of two important lines of research: one exploring the diversity of Ca2+ channels and their physiological roles, and the other pursuing mechanisms of ataxia, dystonia, epilepsy, and migraine. α1A-Subunits are thought to support both P- and Q-type Ca2+ channel currents, but the most direct test, a null mutant, has not been described, nor is it known which changes in neurotransmission might arise from elimination of the predominant Ca2+ delivery system at excitatory nerve terminals. We generated α1A-deficient mice (α1A−/−) and found that they developed a rapidly progressive neurological deficit with specific characteristics of ataxia and dystonia before dying ≈3–4 weeks after birth. P-type currents in Purkinje neurons and P- and Q-type currents in cerebellar granule cells were eliminated completely whereas other Ca2+ channel types, including those involved in triggering transmitter release, also underwent concomitant changes in density. Synaptic transmission in α1A−/− hippocampal slices persisted despite the lack of P/Q-type channels but showed enhanced reliance on N-type and R-type Ca2+ entry. The α1A−/− mice provide a starting point for unraveling neuropathological mechanisms of human diseases generated by mutations in α1A.

Aging accentuates and bone marrow transplantation ameliorates metabolic defects in Fabry disease mice

Fabry disease is an X-linked metabolic disorder caused by a deficiency of α-galactosidase A (α-Gal A). The enzyme defect leads to the systemic accumulation of glycosphingolipids with α-galactosyl moieties consisting predominantly of globotriaosylceramide (Gb3). In patients with this disorder, glycolipid deposition in endothelial cells leads to renal failure and cardiac and cerebrovascular disease. Recently, we generated α-Gal A gene knockout mouse lines and described the phenotype of 10-week-old mice. In the present study, we characterize the progression of the disease with aging and explore the effects of bone marrow transplantation (BMT) on the phenotype. Histopathological analysis of α-Gal A −/0 mice revealed subclinical lesions in the Kupffer cells in the liver and macrophages in the skin with no gross lesions in the endothelial cells. Gb3 accumulation and pathological lesions in the affected organs increased with age. Treatment with BMT from the wild-type mice resulted in the clearance of accumulated Gb3 in the liver, spleen, and heart with concomitant elevation of α-Gal A activity. These findings suggest that BMT may have a potential role in the management of patients with Fabry disease.

Long-term in vitro correction of alpha-L-iduronidase deficiency (Hurler syndrome) in human bone marrow.

Allogeneic bone marrow transplantation is the most effective treatment for Hurler syndrome but, since this therapy is not available to all patients, we have considered an alternative approach based on transfer and expression of the normal gene in autologous bone marrow. A retroviral vector carrying the full-length cDNA for alpha-L-iduronidase has been constructed and used to transduce bone marrow from patients with this disorder. Various gene-transfer protocols have been assessed including the effect of intensive schedules of exposure of bone marrow to viral supernatant and the influence of growth factors. With these protocols, we have demonstrated successful gene transfer into primitive CD34+ cells and subsequent enzyme expression in their maturing progeny. Also, by using long-term bone marrow cultures, we have demonstrated high levels of enzyme expression sustained for several months. The efficiency of gene transfer has been assessed by PCR analysis of hemopoietic colonies as 25-56%. No advantage has been demonstrated for the addition of growth factors or intensive viral exposure schedules. The enzyme is secreted into the medium and functional localization has been demonstrated by reversal of the phenotypic effects of lysosomal storage in macrophages. This work suggests that retroviral gene transfer into human bone marrow may offer the prospect for gene therapy of Hurler syndrome in young patients without a matched sibling donor.

Saúde mental: concepções e práticas profissionais de um campo em tensão

A Reforma Psiquiátrica, atual política de saúde mental, redireciona os recursos da assistência psiquiátrica para o modelo de base comunitária, substituindo o modelo asilar. A abordagem proposta pela Reforma Psiquiátrica procura conjugar o esforço teórico e prático para a construção da Rede de Atenção Psicossocial. O presente trabalho objetivou desvelar concepções e práticas de trabalhadores da saúde mental, construídas na práxis de suas trajetórias profissionais e contextos de vida, em relação à incorporação do modelo de atenção psicossocial ou manutenção de princípios asilares, caracterizadores da tradicional prática profissional em saúde mental. Objetivou também identificar pontos de tensão, que caracterizam interesses de diferentes naturezas, como obstáculos e desafios à implementação da Reforma Psiquiátrica. A pesquisa, de natureza qualitativa, contou com 10 entrevistas de profissionais atuando na área, baseada na técnica de depoimento oral e em roteiro do tipo temático, sendo 3 enfermeiros, 3 psicólogos, 3 psiquiatras e 1 terapeuta ocupacional. Os relatos dos profissionais foram organizados em categorias gerais e específicas tendo em vista a interpretação das narrativas à luz da literatura especializada. Através dos discursos dos profissionais do campo da saúde mental é possível observar que um tensionamento ideológico marca fortemente o espaço da saúde. Alguns profissionais relataram a busca por construir práticas em equipe interdisciplinar, pautadas pelo modelo psicossocial; porém, referem à resistência de outros profissionais da equipe. Praticamente todos os profissionais apresentam discursos de humanização no campo da saúde mental, mas alguns não enunciam visões críticas aos modelos asilares. Alguns trabalhadores revelam a crença na possibilidade de coexistência integrada entre o Modo Asilar e Modo Psicossocial. Para estes trabalhadores de CAPS, é desejável a permanência dos hospitais psiquiátricos e é possível a humanização dos mesmos. Essa questão indica, ao que parece, que as práticas em saúde mental ainda operam sobre premissas epistemológicas diferenciando sujeitos que podem ou não circular no meio social. A existência dos hospitais psiquiátricos, considerados como instituições totais, é problematizada e questionada pela Luta Antimanicomial, indica a permanência da lógica asilar que respalda a continuidade dos hospitais, exclusivamente psiquiátricos, entre os serviços de atendimento, com o apoio de parte dos profissionais da rede de saúde mental. Concordantes com a possibilidade de coexistência do modelo asilar e modelo psicossocial, estes profissionais permitem-nos demonstrar que mesmo uma visão clínica pretensamente humanizadora, que defenda em seu discurso um tratamento digno, pode operar no modelo teórico-metodológico positivista e não está necessariamente vinculada a uma postura política de sujeitos de direitos e de cidadania. Os profissionais que apresentaram em suas narrativas a não concordância com a permanência dos hospitais psiquiátricos, defendem que as transformações sejam clínicas e políticas nos saberes e nas práticas em Saúde Mental. Estes trabalhadores já fizeram ou fazem parte de movimentos sociais, apontados como lugares de reflexão crítica sobre ideias instituídas contribuindo, ao que parece, para o processo de desnaturalização de concepções construídas culturalmente e orientadoras de práticas profissionais. Diante de tais constatações podemos indagar e refletir se a desinstitucionalização, concreta e simbólica, encontra-se no horizonte de uma política pública de atenção em Saúde Mental que realmente tenha como projeto a sua real implementação e se a permanência dos hospitais psiquiátricos e das comunidades terapêuticas estaria descaracterizando as propostas iniciais da construção da Atenção Psicossocial, considerando os interesses privados e a manutenção da lógica asilar, contrários aos princípios do SUS.

The role of catastrophic misinterpretation of bodily sensations and panic self-efficacy in predicting panic severity

This study investigated the role of both negative and positive cognitions in predicting panic severity in an international sample of patients diagnosed with panic disorder (with and without agoraphobia). One hundred and fifty-nine patients were administered the Brief Bodily Sensations Interpretation Questionnaire (BBSIQ), the Self-efficacy to Control Panic Attacks Questionnaire, and the Panic and Agoraphobia Scale (PAS) prior to receiving treatment. Regression analyses indicated that both catastrophic misinterpretation of bodily sensations and panic self-efficacy independently predicted panic severity. The influence of panic self-efficacy upon panic severity remained significant even after controlling for the presence or absence of agoraphobia. There was no evidence to suggest a moderating relationship between the two cognitive factors. Results are discussed in terms of the need to consider both negative and positive cognitions in cognitive accounts of panic disorder. (C) 2002 Elsevier Science Inc. All rights reserved.
