ABSTRACT

OBJECTIVES: To estimate the incidence of dementia in a community-dwelling older population from São Paulo city, Brazil. METHODS/DESIGN: This two-phase prospective cohort study evaluated a representative cluster sample of 1370 individuals aged 60 years old and over from three different socioeconomic levels. The community screening phase consisted of a tested combination of cognitive and functional tests administered among the subjects and informants. In the hospital diagnosis phase, the Cambridge Examination was performed; the diagnosis of dementia and dementia subtypes was made according to DSM IV criteria. Incidence rates were expressed in person-years, multiplied by 1000. The risk of developing dementia was calculated using Cox regression. RESULTS: Among 1370 eligible subjects, 678 were accessed, and 489 completed the evaluation. Forty-two subjects were diagnosed with dementia. The incidence rate of dementia and Alzheimer's disease (AD) were 11.2 (95% CI: 8.0-15.1) and 8.9 (95% CI: 6.1-12.5) per 1000 person-years, respectively; there were high age-specific rates of dementia among younger individuals. There was a trend of a higher risk of developing AD for women than for men. Multivariate analysis showed that older age, the presence of diabetes and the presence of amnestic MCI increased the risk of developing dementia. CONCLUSIONS: The age-specific rates in younger individuals were expressively higher than in worldwide studies and supposedly affected by cardiovascular morbidity. The higher risk in women in a younger sample corroborated the interaction between sex and AD. The increased risk of amnestic MCI reinforced its contribution to the progression to dementia and AD.

ABSTRACT

Exposure to nanomaterials (NMs) can be considered as human, occupational or environmental. Occupational exposure may be experienced by the workers and/or researchers who develop and produce these products and the hazards inherent to exposure are not yet fully known. Quantitative and qualitative methods are available to estimate the occupational risks associated with the handling of NMs, however, both have limitations. In this context, the objective of this study was to create a Bayesian network (BN) that will allow an assessment of the occupational risk associated with the handling of NMs in research laboratories. The BN was developed considered variables related to exposure, the hazards associated with NMs and also the existing control measures in the work environment, such as collective protection equipment (CPE), administrative measures and personal protection equipment (PPE). In addition to assessing the occupational risk, simulations were carried out by the laboratory manager to obtain information on which actions should be taken to reduce the risk. The development of a BN to assess the occupational risk associated with the handling of NMs is a novel aspect of this study. As a distinctive feature, the BN has measurement control variables in addition to considering CPE, administrative measures and PPE. An advantage of this network in relation to other risk assessment models is that it allows the easy execution of simulations and provides a guide for a decision making by identifying which actions should be taken to minimize the risk.

ABSTRACT

The aim of this study was to determine the accuracy of Bayesian networks in supporting breast cancer diagnoses. Systematic review and meta-analysis were carried out, including articles and papers published between January 1990 and March 2013. We included prospective and retrospective cross-sectional studies of the accuracy of diagnoses of breast lesions (target conditions) made using Bayesian networks (index test). Four primary studies that included 1,223 breast lesions were analyzed, 89.52% (444/496) of the breast cancer cases and 6.33% (46/727) of the benign lesions were positive based on the Bayesian network analysis. The area under the curve (AUC) for the summary receiver operating characteristic curve (SROC) was 0.97, with a Q* value of 0.92. Using Bayesian networks to diagnose malignant lesions increased the pretest probability of a true positive from 40.03% to 90.05% and decreased the probability of a false negative to 6.44%. Therefore, our results demonstrated that Bayesian networks provide an accurate and non-invasive method to support breast cancer diagnosis.

ABSTRACT

O objetivo deste estudo foi avaliar a acurácia das redes bayesianas no apoio ao diagnóstico de câncer de mama. Foram realizadas revisão sistemática e metanálise, que incluíram artigos e relatórios publicados entre Janeiro de 1990 e Março de 2013. Foram incluídos estudos transversais prospectivos e retrospectivos que avaliaram a acurácia do diagnóstico de lesões de mama (condição alvo) usando as redes bayesianas (teste em avaliação). Quatro estudos primários que incluíram 1.223 lesões de mama foram analisados, 89,52% (444/496) dos casos de câncer de mama e 6,33% (46/727) das lesões benignas foram positivas tendo-se como base a análise das redes bayesianas. A área dentro da curva SROC (característica de operação do receptor sumária) foi 0,97, com um valor Q* de 0,92. O uso de redes bayesianas no diagnóstico de lesões malignas aumentou a probabilidade pré-teste para um verdadeiro positivo de 40,03% para 90,05% e diminuiu a probabilidade de um falso negativo para 6,44%. Portanto, nossos resultados demonstraram que as redes bayesianas oferecem um método acurado e não invasivo no apoio ao diagnóstico de câncer de mama.

ABSTRACT

This study aimed to determine the pattern of family functioning on everyday care relationships of adults in the fourth age. This is a study of diagnostic-evaluative nature of adults with 80 or more years old who depend on care, and of their relatives as caregivers. The participants were selected among the registered patients of a Family Health Unit in a district in the suburbs of Belém-PA, Brazil. They were evaluated according to the dynamics of their family, and quality of life related health lifestyle. Most of the elderly rated their families with good functionality. However, data on the elderly and caregivers' quality of life and caregivers' life style only reached the median level, showing some difficulty in the family functioning system. It was concluded that the multiple results obtained through the assessments indicate some practical implications of care to the family unity and confirm the need for multidimensional assessment about the family intervention.

ABSTRACT

User satisfaction analyses in synchronous telemedicine and teleconsultation environments have been widely performed and generally show satisfied users. In the field of asynchronous telemedicine, however, satisfaction studies were performed only in one single location or with a restricted set of users. With the aim of offering an exemplar evaluation of the impact of the statewide use of a large-scale asynchronous telemedicine network on the satisfaction of the involved users, this study presents the results obtained from a survey of the perceived quality of the service by both patients and healthcare staff. For this purpose, a survey with satisfaction questionnaires was performed with 564 patients from seven upstate municipalities and 56 healthcare professionals from 46 municipalities, using a methodology from the process improvement field. The collected data were quantified and underwent statistical analysis, which showed a clear perception of the improvement in the quality of service by both patients and healthcare professionals. The present findings also showed that both patients and healthcare professionals felt that introducing these new technologies was a positive step, even in upstate areas and when they involved great changes in the usual processes of primary care.

ABSTRACT

INTRODUÇÃO: Devido ao possível potencial preditivo das atitudes apresentadas pelos estudantes durante o curso de graduação em Medicina, o diagnóstico e o acompanhamento de aspectos atitudinais necessários ao exercício profissional poderiam propiciar mudanças no processo de formação da identidade profissional para efetivação de uma prática médica renovada. MÉTODO: Estudo de coorte, descritivo e quantitativo, por meio da aplicação, em dois momentos, de uma escala de atitudes (tipo Likert com alpha de Cronbach = 0,87), em que se analisam cinco aspectos (ambiência, conhecimento, crença, ética e social) segundo as Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina. Os sujeitos foram 202 estudantes de Medicina (52,85% mulheres e 47,15% homens), da primeira à oitava fase, com média de idade de 21,45 anos (Q inf: 21 e Q sup: 22,50); 91,50% provenientes da escola particular; 97,52% solteiros; de família de bom padrão de escolaridade e econômico; 91,54% da Região Sul, sendo 48,77% do próprio Estado; 86,63% não exerciam atividades extracurriculares; e 86,07% tinham como meta ingressar na residência médica após a graduação. RESULTADO: Identificados dois grupos, com provável homogeneidade de comportamento, com tendência atitudinal positiva, mais frequente no sexo feminino, demonstrando provável conflito na dimensão crença. CONCLUSÕES: Os estudantes apresentaram alguns aspectos atitudinais positivos relevantes para a prática médica, não havendo diferenças substanciais considerando-se as fases e o período estudado. Foram percebidos possíveis conflitos atitudinais quando analisados os itens de determinados aspectos, permitindo uma reflexão para possível associação com as questões educacionais e fornecendo subsídios para estudos futuros.


INTRODUCTION: During medical school, the students' values and attitudes are affected by knowledge, environment and training. Due to the possible predictive potential, __ the diagnoses and monitoring of the attitude aspects needed for the professional exercise could propitiate changes in the process of the professional identity formation for the implementation of a renewed medical practice. OBJECTIVES: To measure the attitudes and to evaluate the behavior changes during the graduation process. METHOD: A cohort study, descriptive and quantitative, in which it was utilized a questionnaire, that applied in two moments an attitude range (Miranda, 2006) analyzing five aspects: environment, knowledge, beliefs, ethics and society. The attitudes were categorized in positive, negative and conflicting. The subjects were 202 medical students (52.85% women and 47.15% men), from the first to the eighth periods, with a mean age of 21.45 years; 91.50% from private schools; 97.52% single; from good socio-cultural family standards; 91.54% from the South Region, being 48,77% from the State; 86.63% did not perform extracurricular activities; and 86.07% had as their goal to join the residency program after graduation. RESULT: Identified two groups, with a probable homogeneity of behavior, with positive attitudinal trend, more common in females, demonstrating a probable conflict in belief dimension. CONCLUSIONS: Students tended to positive attitudinal aspects___ relevant to the medical practice, and showed no substantial differences considering the phases and the periods studied. Were perceived attitudinal conflicts in certain areas, allowing for a reflection of a possible association with educational issues, and providing subsidies for future studies.

ABSTRACT

PURPOSE: The purpose of the present study was to evaluate the quality of life (QoL) of children with CD and of their parents and to compare it with that of children without CD and of their parents. METHODS: A case-control study was conducted to evaluate the quality of life of children (5-12 years) with CD and one of their parents, compared to the QoL of children without CD (and their parents as their caregivers ). The QoL was assessed by applying the following questionnaires: AUQUEI (children) and WHOQOL-BREF (parents). RESULTS: QoL was evaluated in 33 children with CD, 63 children without CD, and of their respective parents as their parent caregivers (96 adults). QoL total scores were similar between the groups of children with and without CD. However, in the Leisure dimension, the scores of children with CD were significantly lower than those of the controls (P = 0.029). Similarly, when assessing the QoL of the parents, we found scores significantly lower in the social dimension (P = 0.0196) for parents of children with CD compared to parents of children without CD. Family income presented an impact on the QoL in adults, but did not affect children. In CD group, children of mothers who had lower educational levels presented better scores in the function dimension, regarding self-care and autonomy. CONCLUSIONS: There is an impairment of the QoL of children with CD and of their parents, with regard to social life, particularly in the leisure (children) and social (adults) dimensions.

ABSTRACT

OBJECTIVE: To understand the profile of women with type 2 diabetes mellitus, focusing on sociodemographic factors, biometrics and health. METHODS: A quantitative, transversal, prospective study with a stratified random sample, conducted in Florianópolis/SC with 147 women by means of home visits between April and August of 2009. RESULTS: The women had a mean age of 66 years, presented elevated indexes of body weight, capillary glycemia and abdominal circumference, along with a low adherence to non-pharmacological treatment. A low educational level was associated with inadequate glycemic control, no physical activity, and inadequacy of the diet. CONCLUSIONS: Women with lower education constitute a vulnerable group and require health interventions congruent with their capacities of understanding and possibilities of adaptation to treatment.

ABSTRACT

O atual fenômeno de prolongamento da vida entre idosos de modo a chegarem aos 80 anos ou mais não constitui um fato excepcional, porém a tal condição associa-se fragilização pelo envelhecimento, tornando-osmais vulneráveis a várias circunstâncias, constituindo-se um subestrato de idosos da quarta idade que amiúde necessita de cuidados de outrem. Assim, objetivou-se conhecer os padrões de funcionamento das famílias no convívio e cuidados cotidianos de idosos mais velhos no contexto de Florianópolis, SC. O estudo consiste deuma pesquisa diagnóstico-avaliativa pelo método de questionamento entre idosos de 80 e mais anos,dependentes de cuidados e de seus respectivos familiares cuidadores, selecionados entre os inscritos nas unidades de Estratégia de Saúde da Família para avaliar a dinâmica familiar pelo Family APGAR, a qualidade devida pelo WHOQOL e o estilo de vida pela Escala de Nahas. Em sua maioria, os idosos avaliaram sua família como de boa funcionalidade, embora esse dado deva ser visto com reserva, pois, na avaliação tanto da qualidade de vida de ambos quanto do estilo de vida dos cuidadores, as respostas recaíram sobre um nível mediano, denotando certa dificuldade de enfrentamento em família com situações prolongadas de cuidado deidosos da quarta idade.


Nowadays he phenomenon observed in life prolongation among elders with 80 or more years of age, is no longer exceptional. However, that condition is usually associated with fragility due to aging turning the elderly more vulnerable to several circumstances of his life, becoming a substratum from elders in the fourth age who of tenneed care from others. Thus, the aim is to understand families functioning patterns on their daily basis and daily care of the elderly in the context of Florianópolis, SC. Descriptive evaluative diagnosis research, using the method of questioning, had the participation of seniors of 80 years old and over dependent on care along withfamily caregiver that were selected among the ones registered at the Family Health Program, in order to assessfamily dynamics, by Family APGAR, quality of life by WHOQOL and life style by Nahas Scale. Results: The elderly rated their families with good functionality. But, it must be considered with reservations, because on both quality of life evaluations from the elderly and the caregiver, responses were related to an average level,denoting some difficulty on coping within the family regarding care to the elderly.


El prolongamiento de la vida de ancianos que llegan hoy a los 80 años o más ya no es excepcional. Pero, tal condición está asociada a la fragilidad por el envejecimiento, hacién dolos más vulnerables a varias circunstancias, constituyéndose en subestrato de ancianos de la cuarta edad que a menudo necesita de los cuidados de otras personas. Así, el objetivo fue conocer los padrones de funcionamiento de las familias en elconvivio y en los cuidados cotidianos a los ancianos de Florianópolis, SC. El estudio consiste de una investigación diagnóstico-evaluativa con el método de cuestionamiento entre ancianos de 80 años o más, dependientes de cuidados y sus familiares respectivos cuidadores, que fueron seleccionados entre los inscriptosen las unidades de Estrategia de Salud de la Familia para evaluar la dinámica familiar por el Family APGAR, lacalidad de vida por el WHOQOL y el estilo de vida por la Escala de Nahas. En su mayoría, los ancianos evaluaron a su familia como de buena funcionalidad, pero ese dato debe ser visto con moderación, pues en la evaluación de la calidad de vida de ambos en cuanto al estilo de vida de los cuidadores, las respuestas sereferían a nivel promedio, denotando cierta dificultad de enfrentamiento en familia con situaciones prologadas decuidado a los ancianos de la cuarta edad.

ABSTRACT

OBJETIVO: O objetivo do estudo foi investigar a relação entre estresse e Diabetes Mellitus Tipo 2 em mulheres. MÉTODO: Estudo transversal prospectivo, desenvolvido com 147 mulheres, utilizando a Escala de Estresse Percebido (PSS). RESULTADOS: Houve associação entre as variáveis testadas, sendo possível inferir que as mulheres com estresse elevado são as que vivenciaram sofrimento e apresentam controle glicêmico alterado, ou seja, com valores superiores a 180 mg/dL. A maioria relatou sofrimento decorrente de problemas nas relações interpessoais, óbito, doença de familiares e solidão. CONCLUSÃO: Mulheres com DM2 que convivem com estresse e/ou sofrimento constituem grupo vulnerável ao desenvolvimento de agravos à saúde demandando aos serviços de saúde o desenvolvimento de estratégias que modifiquem esta situação.


OBJECTIVE: The objective of this study was to investigate the relation between stress and type 2 Diabetes Mellitus (DM2) in women. METHOD: A transversal prospective study, developed with 147 women, using the Perceived Stress Scale (PSS). RESULTS: There was an association between the variables tested, being possible to infer that women with high stress are those who experienced suffering and have glycemic control with alteration, in other words, with values above than 180 mg /dL. The majority reported suffering due to interpersonal relationship, death, illness in the family and loneliness. CONCLUSION: Women with DM2 that living with stress and / or suffering constitute a group vulnerable to the development of health problems, requiring health services to develop strategies to change this situation.

ABSTRACT

Descriptive study aiming to understand the family dynamics of elderly people aged 80 years or older, receiving family care at home. Caregivers and elderly, registered at the family health unit of Greater Porto, comprised a sample of 107 pairs. Data were collected between 09/2009 and 03/2010. The following instruments were applied: family APGAR, quality of life and lifestyle scale. The results that stand out are: increase in male partners serving as caregivers for dependent partners; substantial inclusion in the list of family caregivers: grandchildren, nieces, nephews, siblings. The caregiver lifestyle was considered regular, as well as the caregiver and elderly’s quality of life, although the family dynamics showed to work well. Limitations prevent further generalizations, but offer relevant support for the development of the family health and family nursing program.


Este é um estudo descritivo que objetivou conhecer a dinâmica de família de idosos com 80 anos ou mais, sob cuidados do familiar cuidador, em domicílio. Cuidadores e idosos, registrados na unidade de saúde familiar da grande região do Porto, compuseram amostra de 107 unidades. Dados colhidos entre 9/2009 e 3/2010, por instrumentos de dinâmica familiar, qualidade de vida e de estilo de vida, resultaram em: aumento de cuidador masculino e de cônjuge idoso de seu par dependente e inclusão substancial no elenco de familiares cuidadores: netas(os), sobrinhas(os) e irmãs(os). Estilo de vida do cuidador revelou-se regular como também a qualidade de vida de ambos: cuidador e idoso, apesar de a dinâmica de família se mostrar de boa funcionalidade. Limitações impedem a generalização dos resultados, porém, fornece subsídios relevantes para o desenvolvimento do programa de saúde familiar e de enfermagem de família.


Se trata de un estudio descriptivo, que tuvo por objetivo conocer la dinámica de familia de ancianos con 80 años o más, bajo cuidados de familiar, en su domicilio. El cuidador y el anciano, que estaban registrados en la unidad de salud familiar de la grande región de la ciudad de Porto, en Portugal, compusieron la muestra de 107 sujetos pareados. Los datos fueron recolectados entre 09/2009 y 03/2010 por medio del APGAR familiar, de calidad de vida y de estilo de vida; los resultados mostraron: aumento de cuidador masculino; conyugue anciano dependiente de su par; e, inclusión substancial de familiares en el elenco de cuidadores (nietas(os), sobrinos(os), hermanas(os). A pesar de la dinámica de la familia mostrarse de buena funcionalidad, el estilo de vida del cuidador y la calidad de vida de ambos (cuidador y anciano) se mostraron regulares. Las limitaciones del estudio impiden la generalización de los resultados; sin embargo ofrece subsidios relevantes para el desarrollo del programa de salud familiar y de enfermería de familia.

ABSTRACT

OBJECTIVE: To evaluate the transepithelial transport of sodium, glucose, potassium, and water and the mRNA level of the sodium-glucose cotransporter (SGLT1) and the facilitated sugar transporter (GLUT2) in the small intestine of iron-deficient rats. METHODS: After 6 wk of receiving diets with low or normal iron content, rats (Wistar-EPM) were subjected to two experiments: 1) evaluation of the transepithelial transport of sodium, glucose, potassium, and water by an "in vivo" experimental model of intestinal perfusion and 2) determination of relative SGLT1 and GLUT2 mRNA levels in the proximal, intermediate, and distal portions of the small intestine by the northern blotting technique. RESULTS: Hemoglobin and hepatic iron levels were statistically lower in the anemic rats. The mean transepithelial transports of sodium (-33.0 µEq · min(-1) · cm(-1), glucose (426.0 µM · min(-1) · cm(-1), and water (0.4 µL · min(-1) · cm(-1) in the small intestine of the anemic rats were significantly lower than in the control group (349.1 µEq · min(-1) · cm(-1), 842.6 µM · min(-1) · cm(-1), and 4.3 µl · min(-1) · cm(-1), respectively, P < 0.05). The transepithelial transport of potassium was similar for both groups. The relative SGLT1 mRNA levels of the anemic rats in the intermediate (1.796 ± 0.659 AU) and distal (1.901 ± 0.766 AU) segments were significantly higher than the values for the control rats (intermediate 1.262 ± 0.450 AU, distal 1.244 ± 0.407 AU). No significant difference was observed for the relative SLGT1 mRNA levels in the proximal segment or for the GLUT2 mRNA levels in all segments. CONCLUSION: Iron deficiency decreases the absorption of glucose, sodium, and water and increases SGLT1 mRNA in the intermediate and distal segments of the small intestine of rats.

ABSTRACT

INTRODUÇÃO: Estudos têm mostrado que as atitudes influenciam o comportamento. O desenvolvimento e a manutenção de determinadas atitudes dos estudantes durante o curso médico podem influenciar a qualidade do cuidado médico dado aos pacientes no exercício da profissão. As Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina reforçam a importância de aspectos atitudinais relevantes para a prática médica. OBJETIVO: Construção e validação de uma escala de atitude do tipo Likert, para avaliar atitudes de estudantes de Medicina considerando as Diretrizes Curriculares Nacionais, adaptadas à realidade sociocultural brasileira. MÉTODO: Na construção da escala foram considerados cinco aspectos: social, ambiência, crença, conhecimento e ética. Os sujeitos foram 202 estudantes do curso de graduação em Medicina, da primeira à oitava fase, sendo 52,85% mulheres e 47,15% homens. Estudo de coorte, descritivo e quantitativo. Os dados foram coletados por meio da aplicação de um questionário e de uma escala de atitudes (do tipo Likert) com 102 proposições. A escala foi aplicada em dois momentos. RESULTADOS: A confiabilidade da escala, medida pelo coeficiente α, de Cronbach, foi igual a 0,87. A escala foi validada (validade de construto) por cinco especialistas. Não houve diferença estatisticamente significante entre as oito fases analisadas. As atitudes observadas foram predominantemente positivas. CONCLUSÃO: O trabalho desenvolvido resultou na definição de um instrumento válido e confiável para medir as atitudes de estudantes de Medicina segundo as dimensões social, ambiência, crença, conhecimento e ética.


INTRODUCTION: Studies have shown that attitudes influence behavior. Developing and maintaining certain attitudes can influence the quality of health care delivered by medical students to their patients. The Brazilian National Guidelines for Medical Education emphasize the significance of the students' attitudes relevant for the medical practice. OBJECTIVES: This study aimed designing and validating an attitude scale to evaluate the impact of the medical curriculum on students' attitudes. METHODOLOGY: The subjects were 202 students (female = 52.85%, male = 47.15%), attending from the first to the eighth phase of the medical undergraduate course. The data for this descriptive and quantitative cohort study were collected using a questionnaire and an attitude measurement scale (5-point Likert scale) containing 102 propositions covering five different factors (social, environmental, belief, knowledge and ethics). RESULTS: Several analyses were undertaken to establish the internal validity of the instrument, including reliability (total = 0.87 and 0.89) and correlation studies. There were no statistically significant differences among the eight analyzed phases. The students showed predominantly positive attitudes. CONCLUSIONS: The final version of the scale was therefore regarded valid and reliable for the assessment of medical students' attitudes.

ABSTRACT

Fundamento: A hipertensão arterial sistêmica é importante causa de morbimortalidade no Brasil. Para seu correto manejo, devemos avaliar os fatores a ela associados, particularmente aqueles considerados modificáveis, como a obesidade e a dislipidemia.Objetivo: Verificar a força de associação dos indicadores de obesidade e dislipidemia com a hipertensão arterial sistêmica, através de uma análise multivariada.Método: Estudo do tipo caso-controle, pareado por sexo, raça e idade. A amostra foi composta por 160 pacientes, sendo 80 hipertensos (casos) e 80 não hipertensos (controles), atendidos no Ambulatório de Clínica Médica do Hospital Universitário da Universidade Federal de Santa Catarina. Os procedimentos estatísticos usados foram as medidas descritivas, as tabelas de freqüência, a análise de correspondência múltipla (ACM) e a de regressão logística. Resultados: Houve predominância do sexo feminino (114/160 [71,3%]) e da raça branca (126/160 [78,8%]), com média geral de idade semelhante para casos e controles (55,6 ± 10,4 e 55,8 ± 11,6 anos, respectivamente), bem como a porcentagem de pacientes com idade ³ 60 anos (maior que um terço, em ambos os grupos). A ACM mostrou associação positiva das medidas antropométricas alteradas (índice de massa corporal, circunferência da cintura, relação cintura/quadril) e forte associação de níveis indesejáveis de triglicerídeos com hipertensão arterial sistêmica. Quando aplicada a regressão logística, somente valores inadequados da relação cintura/quadril e a hipertrigliceridemia apresentaram associação estatisticamente significante. Conclusão: Pode-se inferir que a hipertensão apresenta maior associação com a alteração da relação cintura/quadril e dos triglicerídeos.

ABSTRACT

O objetivo desta pesquisa é investigar a aplicabilidade de diferentes operações aritméticas difusas t-normas et-conomas, implementadas através dos neurônios difusos propostos por Kwan-Cai e Hirota-Pedrycz. O sistema neuro-difuso para auxiliar no diagnóstico de doenças epilépticas (SNDDE) representa uma ajuda no diagnóstico de eventos epilépticos e eventos não epilépticos. O sistema contém conhecimento médico representado na forma de regras difusas utilizando o método de inferência difuso Mamdani, baseado no modelo perceptron multilayer (MLP). O processo de aprendizagem consiste em atualizar os pesos sinápticos através das operações aritméticas difusas t-normas e t-conormas. O sistema contém 14 unidades de entrada, representando os sintomas apresentados pelos pacientes, correspondendo a um eventoepiléptico ou um evento não epiléptico. A entrada da redecontém valores quantitativos, ou seja, quantidade de sintomas apresentados pelos pacientes durante um evento epiléptico ou um evento não epiléptico. A amostra estudada foi de 244 pacientes, com maior freqüência no sexo feminino. Os resultados mostram que as operações aritméticas difusas Soma/Produto de Einstein E(OU), implementadas com o neurônio difuso proposto por Kwan-Cai, obtiveram os melhores índices de acerto do sistema e os melhores resultados de sensibilidade e especificidade, com 93,58%, 90,69% e 96,82%, respectivamente. O SNDDE proposto combinou a capacidade das redes neurais artificiais na classificação de padrões juntamente com a abordagem qualitativa da lógica difusa, levando a uma maior taxa de acertos do sistema.

ABSTRACT

JUSTIFICATIVA E OBJETIVOS: O controle do desconforto dos pacientes internados em unidade de terapia intensiva (UTI) tem-se tornado essencial na prática da Medicina intensiva. Os fármacos sedoanalgésicos podem influenciar na morbimortalidade do paciente crítico. Agentes a2-agonistas podem ter um futuro interessante nas UTI. O objetivo deste estudo foi avaliar a administração da clonidina para a sedoanalgesia de pacientes sob ventilação mecânica (VM) prolongada. MÉTODO: Estudo de coorte histórico, onde foram selecionados os prontuários dos pacientes internados na UTI entre janeiro e dezembro de 2006, sob sedação, analgesia e ventilação mecânica por período > 7 dias. Foram anotados os dados demográficos, clínicos e terapêuticos desses pacientes, que foram subdivididos em três grupos: G1 - medicados com clonidina e outros sedoanalgésicos, G2 - medicados com mais de três fármacos sedoanalgésicos, exceto clonidina, e G3 - medicados com midazolam e fentanil. Registrou-se a dose média diária da clonidina, anotando-se, antes da sua administração, 6 e 24 horas após, os valores da freqüência cardíaca e pressão arterial. Para a análise estatística foram utilizados os testes Análise de Variância (ANOVA), t de Student, c² sendo considerado significativo quando p < 0,05. RESULTADOS: Foram avaliados 55 pacientes. Quinze (27,3 por cento) pertenciam ao G1, 11 (20 por cento) ao G2, 29 (52,7 por cento) ao G3. A idade média dos pacientes foi 44 (G1), 50 (G2) e 55 (G3) anos (p = NS). O índice APACHE II médio dos grupos foi 18 (G1), 20,4 (G2), 20,7 (G3) (p = NS). Os pacientes do G1 e G2 permaneceram mais tempo internados na UTI e no hospital (p < 0,05). A dose média administrada de clonidina foi 1,21 ± 0,54 mg/kg/h. Houve diminuição da freqüência cardíaca e da pressão arterial nos pacientes do G1. Esses efeitos não tiveram repercussão clínica nem relação com a dose da clonidina. A mortalidade foi significativamente menor nos pacientes do G1 (20 por cento) em...


BACKGROUND AND OBJECTIVES: The control of patient discomfort in the intensive care unit (ICU) has become an integral part of critical care practice. The sedoanalgesic drugs could influence critically ill patient's morbimortality. Alpha²-adrenoceptor agonists might have an interesting future in ICU. The objective of this study is to evaluate the clonidine use for sedoanalgesia in ICU patients under prolonged mechanical ventilation. METHODS: Historical cohort study. Admitted patient files, January-December 2006, which stayed under mechanical ventilation, analgesia and sedation > 7days were analyzed. Demographic, clinical features and therapeutic data concerning analgesia and sedation were remarked. The data allowed classify the patients in three different groups: G1 = patients that used clonidine and other drugs; G2 = patients that used three or more drugs, without clonidine and G3 = patients that used fentanyl and midazolam. The mean daily doses of infused clonidine were registered, and the values of heat rate (HR), blood arterial pressure (BAP) before starting use of clonidine, after six hours and 24 hours were also registered. Statistical analyzes were performed using Variance Analysis (ANOVA), t tests and x² (significance p < 0.05). RESULTS: Were selected 55 patients. Fifteen (27.2 percent) belonged to G1, 11 (20 percent) belonged to G2 and 29 (52.7 percent) belonged to G3. The mean age of patients was 44 (G1), 50 (G2) and 56 (G3) (p = NS). The mean score APACHE II was 18 (G1), 20.4 (G2) and 20.7 (G3) (p = NS). G1 and G2 patients presented higher ICU length-of-stay (p < 0.05). The mean dose of clonidine used was 1.21 ± 0.54 mg/kg/min. G1 patients had HR and BAP decreased, however these effects were not considered clinically relevant. The mortality was lower in the patients from G1 (20 percent) when compared to G2 (54.5 percent) and G3 (62 percent) (p < 0.05). CONCLUSIONS: The clonidine use to analyzed patients did not result in clinical...
