Depressão em hospital geral: avaliação do desepenho de escalas de rastreamento e desenvolvimento de instrumento para uso na rotina assistencial

O presente estudo desenvolve-se numa perspectiva prática, visando à integração de conhecimentos gerados pela pesquisa a atividades assistenciais no hospital geral universitário, dirigindo-se, especificamente, à questão da detecção da depressão. A depressão é um problema de saúde pública no mundo inteiro, transtorno mental de alta prevalência, com elevado custo para os sistemas de saúde. Entre pacientes clínicos e cirúrgicos, hospitalizados, aumenta a complexidade dos tratamentos, implica maior morbidade e mortalidade, importando também no aumento do tempo e dos custos das internações. Por outro lado, a depressão é subdiagnosticada. Este estudo, originado de um projeto cujo objetivo foi criar um instrumento para a detecção de depressão, utilizável na rotina assistencial, a partir da avaliação do desempenho de escalas de rastreamento já existentes, desdobra-se em três artigos. O primeiro, já aceito para publicação em revista indexada internacionalmente, é a retomada de estudos anteriores, realizados no final da década de 1980. É apresentada a comparação da detecção de depressão, realizada por médicos não-psiquiatras e por enfermeiros, no Hospital de Clínicas de Porto Alegre (HCPA), em 1987 e em 2002. O segundo artigo apresenta o processo de construção da nova escala, a partir da seleção de itens de outras escalas já validadas, utilizando modelos logísticos de Rasch. A nova escala, composta por apenas seis itens, exige menos tempo para sua aplicação. O terceiro artigo é um estudo de avaliação de desempenho da nova escala, denominada Escala de Depressão em Hospital Geral (EDHG), realizado em uma outra amostra de pacientes adultos clínicos e cirúrgicos internados no HCPA. O segundo e terceiro artigos já foram encaminhados para publicação internacional. Esses estudos, realizados em unidades de internação clínicas e cirúrgicas do Hospital de Clínicas de Porto Alegre, permitiram as seguintes conclusões: a) comparando-se os achados de 1987 com os de 2002, a prevalência de depressão e o seu diagnóstico, em pacientes adultos clínicos e cirúrgicos internados, mantêm-se nos mesmos níveis; b) foi possível selecionar um conjunto de seis itens, que constituíram a nova Escala de Depressão em Hospital Geral (EDHG), baseando-se no desempenho individual de cada um dos 48 itens componentes de outras três escalas (BDI, CESD e HADS); c) a EDHG apresentou desempenho semelhante aos das escalas que lhe deram origem, usando o PRIME-MD como padrão-ouro, com a vantagem de ter um pequeno número de itens, podendo constituir-se num dispositivo de alerta para detecção de depressão na rotina de hospital geral.

Revisão sistemática e meta-análise do uso de antidepressivos no transtorno de ansiedade generalizada

Revisão da Literatura: O Transtorno de Ansiedade Generalizada (TAG) é caracterizado por preocupação excessiva, persistente e incontrolável sobre diversos aspectos da vida do paciente. Tem prevalência entre 1,6% e 5,1% e índice de comorbidades de até 90,4%. As principais comorbidades são depressão maior (64%) e distimia (37%). Os antidepressivos podem ser eficazes no tratamento do TAG. A Medicina Baseada em Evidências (MBE) busca reunir a melhor evidência disponível com experiência clínica e conhecimentos de fisiopatologia. A melhor maneira disponível de síntese das evidências é a revisão sistemática e a meta-análise. Objetivos: Investigar a eficácia e tolerabilidade dos antidepressivos no tratamento do TAG através de uma revisão sistemática da literatura e meta-análise. Sumário do artigo científico: A revisão sistemática incluiu ensaios clínicos randomizados e controlados e excluiu estudos não-randomizados, estudos com pacientes com TAG e outro transtorno de eixo I. Os dados foram extraídos por dois revisores independentes e risco relativo, diferença da média ponderada e número necessário para tratamento (NNT) foram calculados. Antidepressivos (imipramina, paroxetina e venlafaxina) foram superiores ao placebo. O NNT calculado foi de 5,5. A evidência disponível sugere que os antidepressivos são superiores ao placebo no tratamento do TAG e bem tolerados pelos pacientes.

The lived experience of long-term psychiatric hospitalization of four women in Brazil

PROBLEM: What is the experience from long-term psychiatric hospitalization? How can psychiatric nursing contribute to reduce the emotional suffering and the feeling of social exclusion related to this process?METHODS: This study was conducted on four women committed to long periods of psychiatric hospitalization in Brazil. Data were collected through open interviews and drawings made by the patients, and interpreted according to the theory of social representations.FINDINGS: Reports on the patients refer to a process of social exclusion, emotional suffering, and inadequate treatment in the hospital, leading to no other option but recurrent hospitalization.CONCLUSION: Negative experiences related to long-term hospitalization could possibly be minimized through adequate assistance provided by psychiatric nursing in open services, as proposed in the recent Brazilian psychiatric reform.

A study of actinic cheilitis treatment by two low-morbidity CO(2) laser vaporization one-pass protocols

Therapeutic approaches to chronic actinic cheilitis focus on the removal or destruction of diseased epithelium. The CO(2) laser has become an important therapeutic alternative, achieving clinical resolution in around 90% of patients. Although many laser physical parameters have been reported, some are known for their low potential for scar induction without compromising the success of the results. The aim of this clinicohistological study was to compare the therapeutic responses to two low-morbidity protocols involving a single laser pass. A total of 40 patients with chronic multicentric and microscopically proven disease were randomly submitted to two conservative CO(2) laser protocols using a bilateral comparative model. The degree of histological atypia of the epithelium was determined in 26 patients both pre- and postoperatively for both protocols. Other histological phenomena were assessed in addition to this central analysis parameter. Clinical recurrence occurred in 12.5% of patients for each protocol, together with a significant reduction in the degree of epithelial atypia (p < 0.001), which was occasionally complete. However, no difference was found between the protocols (p > 0.05). Using these morphological parameters it was not possible to determine whether postoperative epithelial atypias in part of the sample were reactive or residual in nature. A few patients may show minor postoperative lesions. Due to their potential to achieve clinical and importantly microscopic resolution, the studied protocols may be used for mild through moderate dysplastic epithelium and clinically diffuse disease.

Feelings and Perceptions of Women in the Pregnancy-Puerperal Cycle Who Survived Severe Maternal Morbidity

Objetivou-se compreender a experiência relativa à morbidade materna grave, a partir de um grupo de mulheres que vivenciou esse problema. Adotaram-se os preceitos metodológicos da pesquisa qualitativa, sendo o Discurso do Sujeito Coletivo o referencial metodológico. Foram entrevistadas 16 mulheres que vivenciaram a morbidade materna grave. Os resultados foram discutidos a partir de quatro temas: descrevendo o desejo e o planejamento para ter um filho, percebendo seu problema de saúde, sua influência na gestação e para o concepto, passando pelo choque inicial no pós-parto e experienciando a situação de risco: desejos, frustrações e superação. Espera-se que este trabalho possa contribuir para qualificar a assistência de enfermagem, especialmente para reconhecer a diversidade e amplitude de necessidades que mulheres apresentam em situações de morbidade grave, durante o ciclo gravídico puerperal.

Influence of sedation on morbidity and mortality in the intensive care unit

CONTEXTO: Embora cerca de 30% a 50% dos pacientes hospitalizados em unidades de terapia intensiva (UTI) recebam algum tipo de sedativo, existe escassez de informações sobre efeitos adversos desta prática, especialmente no Brasil. Estes efeitos podem ser significantes e o uso de sedativos é associado a elevação de infecção e mortalidade, mesmo sendo difícil avaliar o impacto clínico deste procedimento. OBJETIVO: Avaliar o impacto da sedação sobre incidência de complicações e mortalidade em doentes graves durante internação em unidade de terapia intensiva. TIPO DE ESTUDO: Estudo prospectivo. LOCAL: Unidade de Terapia Intensiva Cirúrgica da Universidade Federal de São Paulo (UNIFESP) - Escola Paulista de Medicina. PARTICIPANTES: Após excluídos pacientes que permaneceram menos de 24 horas ou sem exames indispensáveis para o cálculo do índice de gravidade (APACHE II), restaram 307 pacientes. Estes foram divididos em dois grupos: Grupo Sedado e Grupo Não Sedado. Constatada heterogeneidade com relação ao APACHE II, foram pareados 97 sedados e 97 não sedados com idênticos índices de gravidade. VARIÁVEIS ESTUDADAS: Impacto da sedação e das técnicas sobre a mortalidade, tempo de internação, além da incidência de escara de decúbito ou pressão, trombose venosa profunda e infecção. RESULTADOS: Não houve diferença na incidência de trombose venosa profunda, entre os grupos Sedado e Não Sedado, enquanto que escara de decúbito foi significativamente maior nos sedados (p = 0,03). Infecção foi detectada em 45,4% dos pacientes com sedação e em 21,6% dos pacientes sem sedação (p = 0,006). A mortalidade para os pacientes que não receberam qualquer tipo de sedativo foi de 20,6% e, para aqueles que foram sedados durante a internação, foi de 52,6% (p < 0,0001). CONCLUSÕES: Conclui-se que a sedação está associada a maior duração da internação, morbidade e mortalidade significativas. Apesar da intensidade das associações encontradas, não é possível estabelecer relação causal entre sedação e mortalidade.

Complicações psiquiátricas do uso crônico do álcool: síndrome de abstinência e outras doenças psiquiátricas

A síndrome de abstinência alcoólica é um quadro agudo, caracterizado por um conjunto de sinais e sintomas autolimitados, com gravidade variada, secundário à interrupção total ou parcial do consumo de álcool, podendo ser associado a inúmeros problemas clínicos e/ou outros transtornos psiquiátricos. O objetivo deste artigo é rever as principais complicações psiquiátricas secundárias à síndrome de abstinência alcoólica, como convulsões e delirium tremens, bem como algumas outras condições psiquiátricas associadas à dependência de álcool, como as síndromes de Wernicke Korsakoff e de Marchiava Bignami. Pretende-se, com isso, auxiliar no diagnóstico precoce e tratamento adequado, minimizando assim a morbidade e a mortalidade associadas a tais complicações.

Psychiatric disorders and psychiatric consultation in a general hospital: A case- control study

Introduction: Psychiatric consultation (PC) has been considered an efficient tool to develop research, to track and to give assistance benefiting patients, health professionals and the institution. However, it has not been much used in Brazil. Although 30 to 50% of general hospital (GH) inpatients may present a psychiatric disorder, only 1 to 12% of them are referred to assessment. The aims of this study were: to assess mental disorders in a GH; to identify which of these patients are sent to psychiatric care; to verify alleged reasons for referral to psychiatric consultation, and to examine the relationship between PC and psychiatric learning (during medical school and residence). Methods: A case-control patient study was conducted (47 cases and 94 controls) to analyze in detail the following variables: socio-demographic; clinical; degree of information (about the disease and diagnostic/therapeutic procedures), and relationship between patient and health team. Psychiatric diagnoses were made according to the ICD- 10 criteria. The Self Report Questionnaire (SRQ), the CAGE and Brief Psychiatric Rating Scale (BPRS) were used as well as a specifically designed questionnaire to collect clinical and demographic data. Results: Behavioral alterations, either of elation or of depression, were the main for requesting a PC; 95.8% of the cases and 27.7% of the controls had a mental disorder. Organic mental disorders and alcohol-related disorders were the most frequent diagnoses in group I (cases), while anxiety, depressive and alcohol-related disorders were predominant in group II (controls). Control group patients were better informed and more able to establish an appropriate relationship with the health team than case patients. The logistic regression showed CAGE-positive patients having 12.85 times greater risk of being referred to PC, followed by unemployed patients (2.44 times more PC referrals). Discussion: The SRQ and CAGE were quite useful in the screening of possible patients and might be important for medical students to learn and use as generalists. Further research is needed to verify if and how the newly-established service will improve the diagnostic and treatment skills of our students.

Level of insight and clinical features of obsessive-compulsive disorder with and without body dysmorphic disorder

Introduction: Body dysmorphic disorder (BDD) and obsessive-compulsive disorder (OCD) have several similarities and are included among the obsessive-compulsive spectrum of disorders. However, the content of preoccupations and level of insight of BDD patients differ from OCD patients. Objective: To compare the level of insight regarding obsessive-compulsive symptoms (OCS) and other clinical features in OCD patients with and without comorbid BDD. Methods: We evaluated 103 OCD patients (n=25, comorbid BDD), according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria using the Structured Clinical Interview for DSM-IV, the Yale-Brown Obsessive-Compulsive Scale, the University of Sao Paulo Sensory Phenomena Scale, the Beck Depression and Anxiety Inventories, and the Brown Assessment of Beliefs Scale. Resylts: The study groups differed significantly on several clinical features, including level of insight. A worse level of insight regarding OCS was independently associated with the presence of comorbid BDD. Lower educational level, more psychiatric comorbidities, presence of somatic and hoarding obsessions, and presence of intrusive images were associated with BDD comorbidity, even after adjusting for possible confounders. Conclusion: The presence of BDD in OCD patients is associated with poorer insight into obsessional beliefs and higher morbidity, reflected by lower educational levels and higher number of psychiatric comorbid disorders in general.

Risk factors for vascular dementia in elderly psychiatric outpatients with preserved cognitive functions

The aim of the study was to assess risk factors for vascular dementia (VaD) in elderly psychiatric outpatients without dementia, and to determine to what extent clinical interventions targeted such risk factors. Out of 250 clinical charts, 78 were selected of patients over 60 years old, who showed no signs of dementia. Information was obtained regarding demographics, clinical conditions (diagnosis according to ICD-10), complementary investigation, cognitive functions (via CAMCOG), neuroimaging, and the presence of risk factors for VaD. Depression was the most prevalent psychiatric disorder (74%). A great majority of the patients (86%) had at least one risk factor for VaD. One-third of the sample showed three or more risk factors for VaD. The clinical conditions related to risk factors for VaD were hypertension (48.7%), heart disease (30.8%), hypercholesterolemia (25.6%), diabetes mellitus (23.1%), stroke (12.8%), tryglyceride (12.8%), and obesity (5.1%). In terms of lifestyle, smoking (19.2%), alcohol abuse (16.7%), and sedentarism (14.1%) were other risk factors found. Definite risk factors for VaD were found in 83.3% of the patients. Previous interventions targeting risk factors were found in only 20% of the cases. The high rates of risk factors for VaD identified in this sample suggest that psychiatrists should be more attentive to these factors for the prevention of VaD. © 2007 Elsevier B.V.

Brazilian network for the surveillance of maternal potentially life threatening morbidity and maternal near-miss and a multidimensional evaluation of their long term consequences

Background. It has been suggested that the study of women who survive life-threatening complications related to pregnancy (maternal near-miss cases) may represent a practical alternative to surveillance of maternal morbidity/mortality since the number of cases is higher and the woman herself is able to provide information on the difficulties she faced and the long-term repercussions of the event. These repercussions, which may include sexual dysfunction, postpartum depression and posttraumatic stress disorder, may persist for prolonged periods of time, affecting women's quality of life and resulting in adverse effects to them and their babies. Objective. The aims of the present study are to create a nationwide network of scientific cooperation to carry out surveillance and estimate the frequency of maternal near-miss cases, to perform a multicenter investigation into the quality of care for women with severe complications of pregnancy, and to carry out a multidimensional evaluation of these women up to six months. Methods/Design. This project has two components: a multicenter, cross-sectional study to be implemented in 27 referral obstetric units in different geographical regions of Brazil, and a concurrent cohort study of multidimensional analysis. Over 12 months, investigators will perform prospective surveillance to identify all maternal complications. The population of the cross-sectional component will consist of all women surviving potentially life-threatening conditions (severe maternal complications) or life-threatening conditions (the maternal near miss criteria) and maternal deaths according to the new WHO definition and criteria. Data analysis will be performed in case subgroups according to the moment of occurrence and determining cause. Frequencies of near-miss and other severe maternal morbidity and the association between organ dysfunction and maternal death will be estimated. A proportion of cases identified in the cross-sectional study will comprise the cohort of women for the multidimensional analysis. Various aspects of the lives of women surviving severe maternal complications will be evaluated 3 and 6 months after the event and compared to a group of women who suffered no severe complications in pregnancy. Previously validated questionnaires will be used in the interviews to assess reproductive function, posttraumatic stress, functional capacity, quality of life, sexual function, postpartum depression and infant development. © 2009 Cecatti et al.

The effects of soil pollution and its relation with morbidity in shoreline areas

Soil and subsoil pollution is not only significant in terms of environmental loss, but also a matter of environmental and public health. Solid, liquid and gaseous residues are the major soil contamination agents. They originate from urban conglomerates and industrial areas in which it is impossible to emphasize the chemical, petrochemical and textile industry; thermoelectric, mining, and ironmaster activities. The contamination process can thus be defined as a compound addition to soil, from what qualitative and or quantitative manners can modify soil's natural characteristics and use, producing baneful and deteriorative effects on human health. Studies have shown that human exposition to high concentration of some heavy metals found on soil can cause serious health problems, such as pulmonary or kidney complications, liver and nervous system harm, allergy, and the chronic exposition that leads to death. The present study searches for the correlation among soil contamination, done through a geochemical baseline survey of an industrial contamination area on the shoreline of Sao Paulo state. The study will be conducted by spatial analysis using Geographical Information Systems for mapping and regression analysis. The used data are 123 soil samples of percentage concentration of heavy metals. They were sampled and spatially distributed by geostatistics methods. To verify if there is a relation between heavy metals soil pollution and morbidity an executed correlation and regression analysis will be done using the pollution registers as the independent variables and morbidity as dependable variables. It is expected, by the end of the study, to identify the areas relation between heavy metals soil pollution and morbidity, moreover to be able to provide assistance in terms of new methodologies that could facilitate soil pollution control programs and public health planning. © 2010 WIT Press.
