Deficit and non-deficit schizophrenia do not differ regarding season of birth in Brazilian Southern and Southeast regions

Objectives: There is a 5%-10% excess of births in winter and spring among the patients with schizophrenia born in the northern hemisphere. However, in patients with the deficit syndrome of schizophrenia, there is a slight over-representation of births in summer. In this study, we aimed at verifying whether the same patterns are found in patients with schizophrenia born in the Brazilian South and Southeast regions. Methods: Seventy-six patients with schizophrenia were assessed for demographics and psychopathology and also categorized for the presence of deficit syndrome. Patients with deficit and non-deficit schizophrenia were compared for the season of birth. In addition, we compared psychopathological variables between patients born in all four seasons. Results: There was no significant difference in the distribution of births according to the seasons. Although two thirds of the patients with deficit syndrome were born in the summer and autumn, this over-representation did not reach statistical significance. We found no differences regarding psychopathology between patients born in all four seasons. Conclusion: In the South and Southeast regions of Brazil, there was no significant excess of births in the summer between schizophrenic patients with deficit syndrome, neither was an excess of births in winter and spring in the overall sample of patients with schizophrenia.Objetivos: Entre os pacientes com esquizofrenia originários do hemisfério norte, observa-se um excesso de 5%-10% de nascimentos no inverno e na primavera. Entretanto, entre os pacientes com a forma deficitária da doença, há uma pequena sobrerrepresentação de nascimentos no verão. Neste estudo, buscou-se verificar se tais associações se repetem entre os pacientes com esquizofrenia nascidos nas regiões Sudeste e Sul do Brasil. Métodos: Setenta e seis pacientes com esquizofrenia foram avaliados quanto a características sociodemográficas e psicopatológicas e categorizados quanto à presença da síndrome deficitária. Pacientes com e sem síndrome deficitária foram comparados quanto à estação de nascimento. Adicionalmente, compararam-se características psicopatológicas entre pacientes nascidos nas quatro estações do ano. Resultados: A distribuição de nascimentos de acordo com as estações não apresentou diferenças significativas. Entre pacientes com síndrome deficitária, dois terços nasceram no verão e outono, mas essa diferença não alcançou significância estatística. Não foram encontradas diferenças psicopatológicas relacionadas à estação do ano de nascimento. Conclusão: Nas regiões Sul e Sudeste do Brasil, não foi observado o excesso de nascimentos no verão entre pacientes ESquizofrênicos com síndrome deficitária, bem como não foi constatado excesso de nascimentos no inverno e primavera no grupo geral de pacientes com esquizofrenia.337340Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Insight in psychosis: a conceptual analysis

INTRODUCTION: In the context of clinical psychiatry, insight is defined as a subcategory of self-awareness of patients, which is related to the recognition of the pathological manifestations that affect them and also the appreciation of the changes that these manifestations cause in their interaction with the outside world. OBJECTIVE: To examine the forms of presentation of insight in schizophrenia and other psychoses. METHODS: Conceptual analysis, with illustrative clinical vignettes, of the relation between insight and several symptomatologic dimensions of schizophrenia and related conditions, regarding clinical, neurocognitive, psychodynamic and transcultural aspects. RESULTS: From a conceptual point of view, the construct is shaped by the theoretical approach adopted; from a clinical point of view, its presentation in psychoses is the result of the interaction with different symptomatologic areas and subjective and cultural aspects of the patient. CONCLUSION: Psychopathology assessment of insight must consider the complexity of the phenomenon, the theoretical approach used, and the clinical purpose for which it is done.INTRODUÇÃO: No contexto da psiquiatria clínica, insight ou crítica da doença é definida como uma subcategoria do autoconhecimento dos pacientes relativa ao reconhecimento das manifestações patológicas que os afetam e também à apreciação das mudanças que tais manifestações causam na sua interação com o mundo. OBJETIVO: Examinar as formas de apresentação do insight na esquizofrenia e em outras psicoses. MÉTODOS: Análise conceitual, com vinhetas clínicas ilustrativas, da relação entre insight e as diversas dimensões sintomatológicas da esquizofrenia e condições relacionadas, considerando aspectos clínicos, neurocognitivos, psicodinâmicos e transculturais. RESULTADOS: Do ponto de vista conceitual, o construto é conformado pela perspectiva teórica adotada; do ponto de vista clínico, sua apresentação nas psicoses é a resultante da interação com os diferentes domínios sintomatológicos e aspectos subjetivos e culturais do paciente. CONCLUSÃO: A avaliação psicopatológica do insight deve levar em conta a complexidade do fenômeno, o recorte teórico em que está situada e a finalidade clínica com que é realizada.13514

Hazardous use of alcohol among undergraduate students at a public university

Background The potentially harmful consequences of alcohol use among undergraduates have become a growing concern in recent years. Objectives This study aimed to determine the prevalence of hazardous use of alcohol in this population and to identify demographic and psychosocial factors associated with this pattern of consumption. Methods This was a cross-sectional study using an anonymous and self-completed questionnaire in the classroom. The questionnaire was administered to 1,290 enrolled male and female students, which comprised a proportional sample of the main areas of knowledge at University of Campinas. The questionnaire produced sociodemographic and psychosocial profiles and the Alcohol Use Disorders Identification Test was used to detect hazardous use of alcohol. Results The prevalence of hazardous use of alcohol among the study participants was 24%. Male gender, subjective perceived social support in case of difficulties, being sexually active, not dating, having smoked tobacco cigarettes or marijuana, and having used other illicit psychoactive substances were associated with hazardous use of alcohol. Discussion Variables related to gender, sexuality, affective partnerships, and consumption of other psychoactive substances were associated with hazardous use of alcohol, which was identified in a quarter of the evaluated students, and indicate the need for strategies to prevent and to treat problems

Anorexia nervosa and Wernicke-Korsakoff syndrome: a case report

<p>Abstract</p> <p>Introduction</p> <p>Wernicke's encephalopathy is an acute, potentially fatal, neuropsychiatric syndrome resulting from thiamine deficiency. The disorder is still greatly under-diagnosed, and failure to promptly identify and adequately treat the condition can lead to death or to the chronic form of the encephalopathy - Korsakoff's syndrome. Wernicke's encephalopathy has traditionally been associated with alcoholism but, in recent years, there has been an increase in the number of clinical settings in which the disorder is observed.</p> <p>Case presentation</p> <p>We report the case of a 45-year-old Caucasian woman who arrived at the emergency room presenting signs of marked malnutrition and mental confusion, ataxic gait and ophthalmoplegia. Main laboratory test findings included low serum magnesium and megaloblastic anemia. Brain magnetic resonance imaging revealed increased T2 signal in the supratentorial paraventricular region, the medial regions of the thalamus and the central and periaqueductal midbrain. The diagnosis of Wernicke's encephalopathy was made at once and immediate reposition of thiamine and magnesium was started. The patient had a long history of recurrent thoughts of being overweight, severe self-imposed diet restrictions and self-induced vomiting. She had also been drinking gin on a daily basis for the last eight years. One day after admittance the acute global confusional state resolved, but she presented severe memory deficits and confabulation. After six months of outpatient follow-up, memory deficits remained unaltered.</p> <p>Conclusion</p> <p>In this case, self-imposed long-lasting nutritional deprivation is thought to be the main cause of thiamine deficiency and subsequent encephalopathy, but adjunct factors, such as magnesium depletion and chronic alcohol misuse, might have played an important role, especially in the development of Korsakoff's syndrome. The co-morbidity between eating disorders and substance abuse disorders has emerged as a significant health issue for women, and the subgroup of patients with anorexia nervosa who also misuse alcohol is probably at a particular risk of developing Wernicke-Korsakoff syndrome. The present case report highlights this relevant issue.</p

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
