Influence of migration on the thought process of individuals at ultra-high risk for psychosis

OBJECTIVE To assess the influence of migration on the psychopathological presentation of individuals at ultra-high risk for psychosis (UHR) in São Paulo, Brazil. METHODS This study is part of the Subclinical Symptoms and Prodromal Psychosis (SSAPP) project, a cohort study in São Paulo, Brazil, designed to follow individuals at UHR. After screening with the Prodromal Questionnaire (PQ) and a clinical interview, the Global Assessment of Functioning (GAF) was administered, a neuropsychological assessment was performed, sociodemographic and migration data were obtained. We then analyzed UHR individuals who had migration data to see if migration had any effect on their cognition and psychopathology. Chi-square tests were used for categorical variables, and Student's t test or analysis of variance (ANOVA) were used for nonparametric and parametric distributions, respectively. RESULTS The sample was composed of 42 at-risk subjects, of whom 5 had a migration history in the past two generations. Those with migration history showed significantly more formal thought disturbances (p = 0.012) and sleeping problems (p = 0.033) compared to those without. CONCLUSIONS Our data reinforce migration as a risk factor for psychosis in developing countries as well, and highlights the importance of studying the specific effect of this factor in UHR psychopathology

Surgical treatment for parapneumonic pleural effusion in adults

At least, 40% of all patients with pneumonia will have a parapneumonic pleural effusion (PPE), which is associated to considerable morbidity and mortality. The PPE has three phases: exsudative, fibrinopurulent and organizing, which represent the development of the disease. Despite the great number of therapeutic methods, the PPE management is not well established, because for each phase the success rate of each technique is variable. The objective of this review of literature was to analyze each method available and its indications. Briefly, the use of therapeutic thoracocentesis is restricted to small simple PPE, which are limited to half of the hemithorax. On the other hand, tube thoracostomy has a wider indication: large simple effusions and free-flowing complicated PPE or empyema. For multiloculated cases, the Video-assisted Thoracoscopic Surgery (VATS) is recommendable. Finally, the decortication through thoracotomy is indicated for chronic cases with lung entrapment, although there are evidences that VATS can be used too and, if needed, converted to thoracotomy in the operation room. Regarding thrombolytics, the data available about its efficacy is controversial, thereby its use is still very restrictedCerca de 40% dos pacientes portadores de pneumonia desenvolverão derrame pleural parapneumônico (DPP), o que está associado a considerável morbimortalidade. O DPP possui três fases: exsudativa, fibrino-purelenta e de organização, que representam o progresso da doença. Apesar das várias opções de tratamento existentes, a conduta terapêutica não está bem estabelecida, visto que para cada fase a eficácia de cada método é variável. Procurou-se, nesta revisão de literatura, analisar as diversas opções disponíveis e os critérios que determinam sua indicação. De modo geral, o uso da toracocentese terapêutica deve ser restrito a casos de DPP simples pequenos, que ocupam até metade do hemitórax. Já a toracostomia com drenagem fechada apresenta indicação mais ampla: DPP simples volumosos ou DPP complicados e empiema livres na cavidade. Para tais casos com múltiplas loculações, a decorticação vídeo-assistida (VATS) constitui o tratamento ideal. Por fim, a decorticação por toracotomia está indicada em casos mais crônicos com encarceramento pulmonar, embora existam evidências de que a VATS também pode ser empregada nesses casos e, em caso de necessidade, convertida no intra-operatório para toracotomia. Em relação aos agentes fibrinolíticos, os dados existentes sobre sua eficácia são contraditórios, de modo que seu uso ainda é restrit

Doze anos de experiência em Educação Médica da Liga de Cirurgia Cardiotorácica da Universidade de São Paulo

INTRODUCTION: Academic Leagues (Academic Interest Group) are entities that belong to medical schools and their hospitals. Their goals are research, medical education and health care. The cardiothoracic Surgery League (Liga de Cirurgia Cardiotorácica - LCCT), University of São Paulo Medical School, was founded 12 years ago, aimed at providing undergraduate medical students an opportunity to expand knowledge in cardiothoracic surgery and to take part in scientific studies in the field. OBJECTIVE: To evaluate the experience gained through LCCT implementation. METHODS: Current students and former members of LCCT were submitted to a specific evaluation form, delivered personally or by email, which provided data on the general opinion regarding LCCT's activities, the reasons for answers provided and choice of medical specialties. Furthermore, LCCT's total scientific production was evaluated. Results: Most undergraduate medical students 51/65 (78.5%) and former members 94/121 (77.7%) completed the form. The interest in Cardiothoracic Surgery was the most common reason for joining LCCT 44/161 (27.3%). Most students 32/51 (62.7%) - reported their initial expectations were partially met. Almost every member would recommend a fellow medical student to join LCCT 50/51 (98%) and 25/51 (49%) of them participated in a scientific project linked to LCCT. In total, 47 scientific papers were published having LCCT's medical students as authors or co-authors during the existence of the league. Of the former members who chose a surgical career, 7/52 (13.4%) chose thoracic or cardiovascular surgery. CONCLUSION: LCCT has met its goals, since most current and former members recognized its role in their medical training, besides it is a good way to produce scientific initiation.INTRODUÇÃO: Ligas acadêmicas são entidades pertencentes a faculdades de Medicina e seus hospitais.

Hearing spirits?:Religiosity in individuals at risk for psychosis-Results from the Brazilian SSAPP cohort

In the last decades, biological and environmental factors related to psychosis were investigated in individuals at ultra-risk for psychosis (UHR) to predict conversion. Although religion relates to psychosis in a variety of ways, it is understudied in subclinical samples. Therefore, we assessed the interplay between religion and prodromal symptoms in 79 UHR and 110 control individuals. They were interviewed with the Duke University Religion Index and the Structured Interview for Prodromal Syndromes (SIPS). Organizational religious activity, a measure of how often someone attends churches/temples, was positively related to perceptual abnormalities/hallucinations (Spearman's rho = 0.262, p = 0.02). This relationship was replicated in a path analysis model (β = 0.342, SE = 0.108, p = 0.002), as well as a link between organizational religious activity and lower ideational richness (β = 0.401, SE = 0.105, p = 0.000) with no influence of sex, age, religious denomination, or socioeconomic class. Intrinsic religious activity was negatively correlated with suspiciousness (SIPS P2) (β = -0.028, SE = 0.009, p = 0.002), and non-organizational religious activity was correlated with higher ideational richness (N5) (β = -0.220, SE = 0.097, p = 0.023). We hypothesize that subjects with subclinical psychosis may possibly use churches and other religious organizations to cope with hallucinations. Indeed, Brazil is characterized by a religious syncretism and a strong influence of Spiritism in the popular culture. The mediumistic idea that some might be able to hear and/or see spirits is probably employed to explain subclinical hallucinations in the lay knowledge. Our results emphasize the importance of assessing religion and other region-specific aspects of various cultures when studying UHR individuals. This sort of assessment would enhance understanding of differences in conversion rates, and would help to transpose prevention programs from high-income countries to other settings

Childhood maltreatment in individuals at risk of psychosis: Results from the Brazilian SSAPP cohort

BACKGROUND Childhood maltreatment is a known risk factor for the development of mental disorders, such as psychotic symptoms. An extensive body of literature about childhood maltreatment and mental health has been developed in wealthy countries, but information about this connection is lacking in developing countries. AIMS To explore a possible relationship between childhood maltreatment and ultra-high risk of psychosis in a non-help-seeking population in a low- and middle-income country. METHODS A household survey was conducted in Sao Paulo, Brazil, involving over 2,500 individuals aged 18-30 years who were randomly selected from the general population. The participants underwent screening with the Prodromal Questionnaire. Ultra-high risk status was assessed using the Structured Interview for Prodromal Syndromes, and childhood maltreatment was assessed using the Childhood Trauma Questionnaire. The final sample comprised 87 ultra-high risk individuals and 115 controls. RESULTS Childhood maltreatment was significantly more present among ultra-high risk individuals. In ultra-high risk individuals, physical and emotional neglect were inversely related to grandiosity symptoms, physical abuse was related to perceptual abnormalities and physical neglect was related to disorganized speech and thought. CONCLUSION This is the first study to investigate the relationship between childhood maltreatment and ultra-high risk status and psychopathological features in a large Latin American sample. Further studies in this field are necessary to better understand the specific influence of various early life adversities on psychosis risk

Use of a Bayesian Network Model to predict psychiatric illness in individuals with 'at risk mental states' from a general population cohort

The 'at risk mental state' (ARMS) paradigm has been introduced in psychiatry to study prodromal phases of schizophrenia. With time it was seen that the ARMS state can also precede mental disorders other than schizophrenia, such as depression and anxiety. However, several problems hamper the paradigm's use in preventative medicine, such as varying transition rates across studies, the use of non-naturalistic samples, and the multifactorial nature of psychiatric disorders. To strengthen ARMS predictive power, there is a need for a holistic model incorporating-in an unbiased fashion-the small-effect factors that cause mental disorders. Bayesian networks, a probabilistic graphical model, was used in a populational cohort of 83 ARMS individuals to predict conversion to psychiatric illness. Nine predictors-including state, trait, biological and environmental factors-were inputted. Dopamine receptor 2 polymorphism, high private religiosity, and childhood trauma remained in the final model, which reached an 85.51% (SD = 0.1190) accuracy level in predicting conversion. This is the first time a robust model was produced with Bayesian networks to predict psychiatric illness among at risk individuals from the general population. This could be an important tool to strengthen predictive measures in psychiatry which should be replicated in larger samples to provide the model further learning

A comunicação do diagnóstico "sombrio" na relação médico-paciente entre estudantes de Medicina: uma experiência de dramatização na educação médica

O objetivo do trabalho foi apresentar a dramatização como prática para a humanização da relação médico- paciente entre estudantes do terceiro semestre do curso de Medicina da Universidade Estadual do Ceará (Uece). Por meio de metodologia qualitativa, aplicaram-se perguntas referentes aos sentimentos vivenciados enquanto na posição de médicos e de pacientes, e à vivência com a técnica, após a mesma ser apresentada em sala de aula (n=24).Os dados permitiram identificar que os temas abordados se referiam a doenças graves e perdas. Em relação aos sentimentos, no papel tanto de paciente quanto de médico, demonstraram angústia, impotência, apreensão,medo e ansiedade. Expressaram dificuldades frente ao diagnóstico e à transmissão de má notícia, ao mesmo tempo em que valorizaram a construção do vínculo médico-paciente. Frente à experiência, destacaram a técnica como geradora de auto conhecimento e vivência da futura profissão. Estudos prospectivos devem ser realizados para avaliar o impacto dessa estratégia na humanização da relação médico- paciente e educação médica, explorando o máximo de potencialidade frente às suas limitações
