Clozapine prescription trends in Brazil in the last decade

Objective: Clozapine is a second-generation antipsychotic indicated for treatment-resistant schizophrenia. Studies in several countries have shown a low rate of clozapine use despite the fact that approximately 30% of schizophrenia cases are treatment-resistant. In Brazil, few studies have addressed the frequency and variety of antipsychotic use in individuals diagnosed with schizophrenia (ICD F20). The objective of this study was to measure the rates of clozapine use in this population in the last decade using Brazilian Ministry of Health data. Methods: Prescriptions made between 2010 and 2020 in all 26 states and the Federal District registered at the Outpatient Information System Database from the Brazilian Health System (SIASUS) were evaluated. Results: A total of 25,143,524 prescriptions were recorded in this period, with clozapine representing 8.86% of all antipsychotics. The most frequently prescribed antipsychotic for patients with schizophrenia was olanzapine (35.8%), followed by quetiapine (27.5%). From 2010 to 2020, the rate of clozapine prescriptions in Brazil increased from 7.2% to 10.9%. Conclusions: Despite a slight increase in prescriptions in the last decade, clozapine is still underutilized in Brazil.

Risk of neutropenia among clozapine users and non-users: results from 5,847 patients

Objective: Clozapine is underprescribed due to neutropenia risk. Blood tests every 3 months in those on continuous treatment for > 1 year who have never had an absolute neutrophil count (ANC) < 2,000/µL has been proposed as a monitoring strategy; however, there are no South American data to support this recommendation. This study sought to investigate whether clozapine use and other variables could explain the occurrence of ANC < 1,000/µL in patients with severe mental disorders. Methods: A total of 5,847 subjects were included, 1,038 on clozapine. We performed a Cox regression considering the outcome as ANC < 1,000/µL at any time point. Predictors were sex, age, ethnicity, clozapine use, ANC > 2,000/µL during the first year of blood monitoring, and presence of a severe medical condition. Results: In the Cox regression model, ethnicity (white) (hazard ratio [HR] 0.53; 95%CI 0.29-0.99, p < 0.05) and ANC > 2,000/µL (HR 0.04; 95%CI 0.01-0.10, p < 0.001) were protective factors, while presence of a severe medical condition (HR 69.35; 95%CI 37.45-128.44, p < 0.001) was a risk factor for ANC < 1,000/µL. Other variables were not significant, including clozapine use (HR 1.33; 95%CI 0.74-2.39, p > 0.05). Conclusions: These findings suggest that clozapine does not increase the risk of neutropenia in subjects with ANC > 2,000/µL during the first year of use and in the absence of a severe medical condition. These results could help guide clinical and public-health decisions regarding clozapine blood monitoring guidelines.

Aleitamento materno e quimiocinas: diferenças entre esquizofrenia e controles / Breastfeeding and chemokines: differences in schizophrenia and controls

Introdução: Avaliar a associação entre níveis plasmáticos da quimiocina CCL11, coeficiente de inteligência e prática da amamentação em homens com esquizofrenia em condições psiquiátricas estáveis sob acompanhamento ambulatorial em um serviço de saúde pública. Métodos: Foi realizado estudo caso-controle com 60 indivíduos: 30 pacientes com esquizofrenia e 30 controles saudáveis, dos quais 15 de cada grupo foram expostos ao aleitamento materno e 15 não foram. Foi aplicado questionário abordando questões socioeconômicas, história ao nascer, dados clínicos e alimentação ao nascer. Foi dosada a quimiocina CCL11 e aplicados testes psicológicos para avaliar quociente de inteligência, funcionalidade, sintomas psiquiátricos, curso da doença e diagnóstico. Para os controles, foi utilizada uma escala para descartar doença psiquiátrica. Resultados: A quimiocina CCL11 apresentou valores significativamente mais altos (> 0,5) em pacientes com esquizofrenia quando comparados aos controles. No grupo de amamentados, os esquizofrênicos apresentaram valores significativamente mais altos a nível intermediário (entre 0.106 e 0.5). Não houve correlação da CCL11 com o número de hospitalizações, idade, tempo de diagnóstico e escolaridade. Não foi evidenciada correlação entre tempo de aleitamento materno em relação aos fatores do Brief Psychiatric Rating Scale. Houve uma tendência de correlação entre a idade de início da doença e o aleitamento materno. Foi encontrada correlação positiva do CCL11 com o tempo de aleitamento materno. Ao comparar os pacientes esquizofrênicos que foram aleitados com os que não foram, foi encontrada diferença estatisticamente significativa apenas para o quociente de inteligência. Conclusão: O aleitamento materno está associado a níveis mais baixos de CCL11, escores mais altos de quociente de inteligência e a esquizofrenia. A quimiocina CCL11 é mais alta em quem não amamentou, especialmente nos esquizofrênicos. (AU)

Introduction: To evaluate the association between plasma levels of chemokine CCL11, intelligence quotient, and exposure to breastfeeding in men with schizophrenia under stable psychiatric condition and monitored as outpatients in a public health care unit. Methods: A case-control study of 60 individuals, 30 patients with schizophrenia and 30 healthy controls; in each group, 15 were exposed to breastfeeding and 15 were not. A questionnaire addressing socioeconomic issues, history at birth, clinical data, and feeding at birth was administered. Chemokine CCL11 levels were measured, and psychological tests were applied to assess intelligence quotient, functional status, psychiatric symptoms, disease course, and diagnosis. A scale to rule psychiatric illness was used for the controls. Results: Chemokine CCL11 levels were significantly higher (> 0.5) in patients with schizophrenia than in controls. In the breastfed group, patients with schizophrenia also had significantly higher CCL11 levels, but at an intermediate level (between 0.106 and 0.5). There was no correlation between CCL11 and number of hospitalizations, age, time since diagnosis, or level of education, nor between duration of breastfeeding and the Brief Psychiatric Rating Scale factors. A trend toward a correlation was observed between age at disease onset and breastfeeding. There was a positive correlation between CCL11 and duration of breastfeeding. The comparison of patients with schizophrenia who were breastfed vs those who were not breastfed showed a statistically significant difference only in intelligence quotient. Conclusion: Breastfeeding is associated with lower CCL11 levels, higher intelligence quotient scores, and schizophrenia. Chemokine CCL11 levels are higher in those not exposed to breastfeeding, especially in patients with schizophrenia. (AU)

Management of the pseudobulbar affect (PBA) in Kabuki syndrome combined dextromethorphan-fluoxetine treatment as an alternative to dextromethorphan/quinidine

A case report of a patient with pseudo bulbar affect previous treatments included haloperidol (10mg), Inosina pranobex (600mg), clozapine (600mg), olanzapine (20mg), carbamazepine (200mg), paroxetine (20mg), phenobarbital (100mg) and topiramate (50mg), all suspended at August 2016, with current use of quetiapine (700mg) Chlorpromazine (600mg) (+ 200mg on demand of aggression), clonazepam (4 mg), valproate 2500 mg, propranolol (40mg). that was successful treated with off label treatment (dextromethorphan plus quinidine). Previous Brief Psychiatric Rating Scale and Clinical Global Impression-Improvement was applied after and before treatment with dextromethorphan (20mg) plus fluoxetine (20 mg, further increased to 40 mg). Previous Brief Psychiatric Rating Scale BPRS score 56 points and Clinical Global Impression-Severity (CGI-S) Score was 6 (severely ill). The addition of dextromethorphan (20mg) and fluoxetine (20 mg, further increased to 40 mg), allowed clear improvement of pathological crying and outbursts, with BPRS decrease of 8 points and Clinical Global Impression-Improvement (CGI-I) 2 (much improved) ­ especially pertaining to PBA related symptoms and aggressive behavior. There were no noticeable side-effects. This case report shown an interesting clinical response. It's could be a great alternative in treatment of pseudobulbar affect symptoms. Even though an only case and a great clinical study be necessary. (AU)

Egg quality assessment at different storage conditions, seasons and laying hen strains / Avaliação da qualidade do ovo em diferentes condições de armazenamento, estações do ano e linhagens de poedeiras

ABSTRACT Eggs are one of nearly perfect protein foods, offering nutrients of great biological value. However, during storage, egg albumen and yolk components may alter and deteriorate egg quality. Therefore, the aim of this work was to assess egg quality during 9-week storage. Parameters such as Haugh unit, weight loss, egg width and length, specific gravity, yolk and albumen dimensions and their pH were evaluated weekly. A total of 270 eggs (n=5) collected from two different hen strains were evaluated under room (20 to 35 °C in summer; 11.2 to 29.7 °C in autumn) and refrigerated (0 to 5 °C in summer; -3.1 to 6.5 °C in autumn) temperatures. For storage time, an unfolding analysis was accomplished by regression analysis using orthogonal polynomials. As a second approach, principal component analysis (PCA) was performed in order to assess correlations among quality parameters on storage conditions and laying hen strains. By the end of the 9-week storage period, eggs kept under refrigeration presented similar quality parameters to eggs stored at room temperature for only 3 weeks. In contrast, eggs kept at room temperature presented faster degradation from week 1 to 5. No differences on egg quality parameters were noticed between white and brown shells eggs. PCA suggests that better egg quality (first week) was associated mainly with higher egg weight and its specific gravity, Haugh unit and albumen height. Eggs stored at room temperature should be consumed in 2 weeks or refrigerated until 8 weeks, preserving internal quality from farm to retail.

RESUMO Os ovos são um dos alimentos que oferecem nutrientes de grande valor biológico. Entretanto, no armazenamento, alguns componentes da clara e gema podem se alterar, deteriorando a qualidade dos ovos. Assim, este trabalho objetivou avaliar semanalmente parâmetros de qualidade como unidade Haugh, perda de peso, largura/comprimento do ovo, densidade específica, dimensões da clara/gema e pH durante 9 semanas de armazenamento. Foram coletados 270 ovos de duas linhagens de poedeiras e avaliados a temperatura ambiente (20 a 35 °C no verão; 11,2 a 29,7 °C no outono) e refrigerada (0 a 5 °C no verão; -3,1 a 6,5 ºC no outono). Para as condições de armazenamento, foi realizada uma análise de desdobramento por regressão por polinômios ortogonais. Ainda, análise de componentes principais (PCA), objetivou avaliar correlações entre parâmetros de qualidade em diferentes condições de armazenamento e linhagens de poedeira. Após 9 semanas de armazenamento, os ovos refrigerados apresentaram qualidade similar àqueles armazenados a temperatura ambiente por 3 semanas. Porém, sem refrigeração, os ovos apresentaram uma degradação mais rápida da semana 1 a 5. Não foram observadas diferenças nos parâmetros de qualidade dos ovos entre as diferentes colorações de casca (linhagens de poedeiras). PCA sugere que a melhor qualidade dos ovos (primeira semana) foi associada principalmente com valores elevados de peso e densidade específica do ovo, unidade Haugh e altura do albúmen. Ovos armazenados a temperatura ambiente devem ser consumidos até duas semanas ou mantidos sob refrigeração até 8 semanas, preservando a qualidade interna desde a granja até o armazenamento no varejo.

Perda significativa de peso em pacientes com esquizofrenia na dieta hipocalórica de longo prazo: estudo piloto / Significant weight loss in patients with schizophrenia in long-term hypocaloric diet: a pilot study

Objetivo: A esquizofrenia está associada ao aumento da obesidade e morbidade por doença cardiovascular. O objetivo do presente estudo foi avaliar alterações no peso e índice de massa corporal (IMC) de pacientes com esquizofrenia após tratamento nutricional de longo prazo. Método: Estudo piloto retrospectivo envolvendo 42 indivíduos com esquizofrenia em tratamento nutricional entre 2004 e 2010. Os prontuários médicos foram revisados após aprovação institucional e coleta de dados para peso, índice de massa corporal (IMC), idade, gênero e dieta. O peso e o IMC foram avaliados no início do tratamento nutricional, após seis meses, após 12 meses e no momento da coleta de dados. Resultados: Houve perda significativa de peso e diminuição significativa do IMC quando comparados a cada grupo com o valor basal (p<0,001). Conclusões: Demonstramos que as intervenções nutricionais podem promover uma significativa perda de peso na esquizofrenia. Estes resultados suportam a importância da intervenção nutricional na esquizofrenia e trazem evidências de que a perda de peso permanece ao longo do tempo.(AU)

Objective: Schizophrenia is associated with increased obesity and morbidity from cardiovascular disease. The aim of the present study was to evaluate changes in weight and body mass index (BMI) of patients with schizophrenia following a long-term nutritional treatment. Methods: Retrospective pilot study involving 42 individuals with schizophrenia on nutritional treatment from 2004 to 2010. Medical charts were reviewed after institutional approval and data collection was conducted for weight, body mass index (BMI), age, gender and diet prescription. Weight and BMI were evaluated at baseline of nutrition treatment, after six months, after 12 months and at the time of data collection. Results: There was a significant weight loss and significant decreased in BMI when compared each group to baseline (p<0.001). Conclusions: We demonstrate that nutritional interventions can promote a significant weight loss in schizophrenia. These results support the importance of nutritional intervention in schizophrenia and bring evidences that weight loss remains along the time.(AU)

Exogenous enzyme complex prevents intestinal soybean meal-induced enteritis in Mugil liza (Valenciennes, 1836) juvenile

ABSTRACT Four soybean meal-based diets containing increasing levels of an enzyme complex (E50, E100, E150 and E200 at 50, 100, 150 and 200 g ton-1, respectively) and one soybean meal-based diet without the enzyme complex (E0) were fed in triplicate to M. liza juveniles in a semi-static flow system with 20 fish per tank for 75 days. There were no differences between the treatments for animal performance parameters, but fish fed the enzyme complex treatment exhibited significantly (P<0.05) higher values of calcium bone retention compared with control fish. Although there was no relationship between bacterial counts in different sections of the gastrointestinal tract or enzyme levels, filamentous bacteria were increased in E50 compared with E150. All of the treatments resulted in higher bacterial counts in the stomach than in intestinal segments. Histological screening showed serious to moderate infiltration of inflammatory cells, modification in villus morphology and necrosis in some cases in fish fed the E0 diet. In addition, fish from the E0 treatment exhibited significantly (P<0.05) lower lipid deposition in the peritoneal cavity. Therefore, the use of low levels of exogenous enzyme is recommended in diets for M. liza when soybean meal is used as the main source of protein.

Trends in elderly psychiatric admissions to the Brazilian public health care system

Objective: To evaluate trends in psychiatric bed occupancy by elderly inpatients in the Brazilian public health care system between 2000 and 2010 and to determine the leading psychiatric diagnosis for hospital admissions. Methods: Data from all 895,476 elderly psychiatric admissions recorded in the Brazilian Public Health Care Database (DATASUS) between January 2000 and February 2010 were analyzed. Polynomial regression models with estimated curve models were used to determine the trends. The number of inpatient days was calculated for the overall psychiatric admissions and according to specific diagnoses. Results: A moderate decreasing trend (p < 0.001) in the number of inpatient days was observed in all geriatric psychiatric admissions (R2 = 0.768) and in admissions for organic mental disorders (R2 = 0.823), disorders due to psychoactive substance use (R2 = 0.767), schizophrenia (R2 = 0.680), and other diagnoses (R2 = 0.770), but not for mood disorders (R2 = 0.472). Most admissions (60 to 65%) were due to schizophrenia. Conclusion: There was a decreasing trend in inpatient days for elderly psychiatric patients between 2000 and 2010. The highest bed occupancy was due to schizophrenia, schizotypal, and delusional disorders.

Heat stroke during long-term clozapine treatment: should we be concerned about hot weather? / Heat stroke durante tratamento de longo prazo com clozapina: devemos nos preocupar com o tempo quente?

Objective To describe the case of a patient with schizophrenia on clozapine treatment who had an episode of heat stroke. Case description During a heat wave in January and February 2014, a patient with schizophrenia who was on treatment with clozapine was initially referred for differential diagnose between systemic infection and neuroleptic malignant syndrome, but was finally diagnosed with heat stroke and treated with control of body temperature and hydration. Comments This report aims to alert clinicians take this condition into consideration among other differential diagnoses, especially nowadays with the rise in global temperatures, and to highlight the need for accurate diagnosis of clinical events during pharmacological intervention, in order to improve treatment decisions and outcomes.

Objetivo Descrever o caso de um paciente com esquizofrenia em tratamento com clozapina acometido por um episódio de heat stroke. Descrição do caso Durante uma onda de calor em janeiro e fevereiro de 2014, um paciente com esquizofrenia em tratamento com clozapina foi inicialmente encaminhado para diagnóstico diferencial de infecção sistêmica e síndrome neuroléptica maligna, tendo obtido o diagnóstico final de heat stroke, tratado com controle de temperatura corporal e hidratação. Comentários Este relato de caso tem como objetivo alertar os clínicos para este diagnóstico diferencial, que pode surgir com mais frequência à medida que as temperaturas globais continuarem a aumentar, e também destacar a importância da realização de um diagnóstico mais acurado, que possa melhorar as decisões de tratamento e os desfechos clínicos para os pacientes.

Terapia comportamental dialética: um protocolo comportamental ou cognitivo? / Dialectical behavior therapy: a behavioral or cognitive protocol?

A terapia comportamental dialética (DBT) é um protocolo clínico inicialmente desenvolvido para o tratamento de comportamentos suicidas e parassuicidas, e posteriormente estendido para algumas psicopatologias, como o transtorno da personalidade borderline. O tratamento envolve a aprendizagem de comportamentos pré-requisitos, divididos nos estágios (1) “alcançando as habilidades básicas”, (2) “redução do estresse pós-traumático” e (3) “resolvendo problemas de vida e aumentando o respeito próprio”. O presente artigo analisa se, e em que medida, a DBT preenche os critérios filosófico-aplicados de inclusão nas terapias baseadas na análise do comportamento. Para isso analisou sua concepção filosófica de base, bem como as estratégias de avaliação e intervenção. Argumentou-se que o embasamento filosófico adotado se aproxima do behaviorismo, devido a sua definição de comportamento, concepção de causas e de seleção. Foram identificadas também estratégias de avaliação e intervenção, com foco na aceitação e na mudança, baseadas em análises funcionais, no reforçamento e na modelagem para a aprendizagem de novas habilidades...

The dialectical behavior therapy (DBT) is a clinical protocol originally developed for the treatment of suicidal and parasuicidal behaviors, and later extended to psychopathology as the borderline personality disorder. Treatment involves learning prerequisites behaviors, divided in stages (1) “attaining basic capacities” (2) “reducing postttraumatic stress” and (3) “increasing self-respect and achieving individual goals”. This article examines whether and how DBT meet the philosophical and applied criteria for inclusion in therapies based on behavior analysis. We revised philosophical conception basis as well as the assessment and intervention strategies. It is argued that the philosophical foundation approaches behaviorism, due to its behavior definition, conceptions of causes and selection. We also identified assessment and intervention strategies, focusing on acceptance and change, based on functional analysis, reinforcement and shaping for learning new skills...

Consequências do uso de cocaína e metanfetamina durante a gravidez / Consequences of cocaine and methamphetamine during pregnancy

Com o objetivo de descrever as consequências do uso da cocaína e metanfetamina durante a gestação, foi realizada revisão crítica das publicações nas seguintes bases de dados: MEDLINE (por meio do PubMed), SciELO, LILACS e Google acadêmico, utilizando-se termos e palavras-chave relacionadas à cocaína, metanfetamina e gestação. O uso desses estimulantes do sistema nervoso central constitui-se em grave problema de saúde pública passível de intervenção, a qual pode reduzir ou até mesmo evitar agravos à saúde da gestante e do feto, além de redução dos gastos públicos com os longos períodos de internação e recuperação da saúde dos usuários. Foram observadas alterações no desenvolvimento infantil, diminuição de atividade motora e dificuldade de sustentar atenção com o uso metanfetamina. Bebês nascidos de mães que abusaram de cocaína durante a gravidez geralmente nascem de parto prematuro, com baixo peso e estatura e circunferência craniana menor do que o normal. Observam-se, ainda, altas taxas de malformação congênita e de mortalidade perinatal. Há também evidências mostrando queda no rendimento escolar, envolvendo distração e déficit de atenção, em crianças cujas mães usaram cocaína na gravidez. Entretanto, muitas dúvidas sobre o assunto ainda permanecem, merecendo maior atenção, em vista da importância do efeito dessas drogas no período gestacional e a repercussão futura no desenvolvimento infantil.

In order to describe the effects of using cocaine and methamphetamine during pregnancy was performed a review of published studies on the threshold of medical data base: MEDLINE (PubMed), SciELO, LILACS and Google scholar, using terms and keywords related to cocaine, methamphetamine and pregnancy. The use of central nervous system stimulants is a serious public health problem susceptible to intervention, which can reduce or even prevent damages to health of the mother and fetus, and reduce public spending long periods of hospitalization and recovery of users’ health. Changes were observed in child development, decreased visual-motor performance and difficulty sustaining attention using methamphetamine. Babies born to mothers who abused of cocaine during pregnancy are often born of premature births, low weight and height and head circumference smaller than normal. There are also high rates of congenital malformation and perinatal mortality. There is also evidence that children who received cocaine through their mothers in the intrauterine stage can have falling in school performance, involving distraction and difficulty concentrating. However, many questions still remain about the issue, deserving more attention, in view of the importance of the effect of these drugs during pregnancy and its future impact on child development.

First report of White spot syndrome virus in farmed and wild penaeid shrimp from Lagoa dos Patos estuary, southern Brazil

In this study, we detected White spot syndrome virus (WSSV) in wild Farfantepenaeus paulensis collected in the Lagoa dos Patos estuary and cultivated Litopenaeus vannamei. This is the first report of WSSV in F. paulensis from Lagoa dos Patos and farmed L. vannamei shrimps in Rio Grande do Sul.

Efeitos de instruções sobre respostas de checagem / Effects of instructions on checking responses

O estudo teve o objetivo de testar o controle verbal de diferentes instruções sobre respostas de checagem. Dois participantes adultos foram instruídos a separar quatro tipos de sementes misturadas. Utilizou-se um delineamento sujeito único ABCA na apresentação das instruções. Os resultados mostraram que a instrução C com descrição de conseqüências aversivas aumentou a freqüência das respostas de checagem, sendo que o participante um o fez em relação à instrução B com autoclítico e o participante dois em relação à instrução A de linha de base. Na fase de reversão ambos os participantes diminuíram a freqüência após a apresentação de uma instrução A sem descrição de conseqüências aversivas. Sugere-se que a instrução C especificando toda a contingência pode ter estabelecido função aversiva para as respostas de separação não-efetivas.

The study had the objective of testing the verbal control of different instructions on checking responses. Two adult participants were instructed to separate four types of mixed seeds. An ABCA single-subject design was used in the presentation of the instructions. The results showed that instruction C with description of aversive consequences increased the frequency of checking the responses. Participant one showed an increase in relation to instruction B with autoclitic and participant two in relation to instruction A of the base line. In the reversion phase both participants reduced the frequency after the presentation of an instruction A without description of aversive consequences. The results suggest that instruction C that specifies the whole contingency established an aversive function for the non-effective separation responses.
