O efeito de intervenções educativas no conhecimento da equipe de enfermagem sobre hipertensão arterial

A hipertensão arterial é um dos principais fatores de risco para as doenças cardiovasculares, sendo grande a responsabilidade da enfermagem na atenção aos hipertensos. Objetivou-se, portanto, avaliar o conhecimento sobre hipertensão e seu tratamento com a equipe de enfermagem, antes e após onze intervenções educativas. Utilizou-se questionário abordando aspectos teóricos ligados ao conhecimento sobre hipertensão em enfermeiros (5), técnicos (2), auxiliares (11) e agentes comunitários (37), de duas Unidades Básicas de Saúde da cidade de São Paulo. Para análise estatística utilizou-se o teste T de Student, análise da variância e p<0,05. Verificou-se aumento no conhecimento após as intervenções educativas para o grupo formado por enfermeiros, técnicos e auxiliares de enfermagem (84,6±12,0% vs 92,7±15,0%, p<0,05), enquanto que para agentes comunitários de saúde não houve mudança significante (80,8±12,2% vs 83,5±24,0%). Portanto, conclui-se que as ações educativas foram efetivas e que devem ser implementadas junto à equipe de enfermagem, considerando que elas podem influenciar no aprimoramento da assistência às pessoas hipertensas.

Efficacy of clarithromycin versus that of clindamycin for single-dose prophylaxis of experimental streptococcal endocarditis.

Clarithromycin is compared with clindamycin for single-dose prophylaxis of streptococcal endocarditis in rats. Human-like kinetics of the two antibiotics prevented endocarditis in animals challenged with both small and large amounts of bacterial inocula. Clarithromycin was marginally superior to clindamycin against small amounts of inocula. Clarithromycin may be considered for endocarditis chemoprophylaxis in human.

Neuromotor performance of normally developing left-handed children and adolescents.

Neuromotor functioning - i.e., timed performance and quality of movements - was examined in 66 left-handed children and adolescents between 5 and 18.5 years by means of the Zurich Neuromotor Assessment. Quality of movements was assessed by the degree and the frequency of associated movements. Results were compared to normative data from 593 right-handers. The overall scores for timed motor performance were similar for left-handers and right-handers, while left-handers had more associated movements than right-handers with both sides. In agreement with previous studies in adults, we found that left-handed children were less lateralized than right-handers. They performed faster with their non-dominant side and slower with their dominant side. This finding was roughly independent of age, which may indicate that handedness does not reflect long-term effects of previous motor experience, but may be primarily attributed to genetic factors.

Custo econômico do tratamento das úlceras por pressão: uma abordagem teórica

O presente artigo consiste numa abordagem teórica sobre a problemática dos custos económicos das úlceras por pressão. Parte-se do conhecimento do problema, numa perspetiva conceptual, para, de seguida, apresentar resultados de estudos de prevalência, a partir dos quais foram delineados estudos de impacto económico. O objectivo deste artigo é o de reflectir sobre os custos económicos associados às úlceras por pressão, quer numa perspetiva global, considerando a repercussão financeira, quer numa vertente personalista, atendendo aos custos intangíveis. Relativamente ao impacto económico das úlceras por pressão, foi efectuada uma estimativa ao nível da Região Autónoma dos Açores do custo total do tratamento por ambiente de cuidados. Nos cuidados domiciliários o custo com o tratamento de todas as categorias é calculado em 7.086.415 euros; nos cuidados hospitalares, em 1.723.509 euros, e nos cuidados prestados em lares de idosos, em 1.002.562 euros. Nos Açores, a estimativa do custo total do tratamento das úlceras por pressão, considerando todas as suas categorias, ronda os 9.812.486 euros. Quanto ao impacto emocional associado, este tem elevados custos para pessoa e para os familiares, nomeadamente pelo sofrimento gerado. De facto, as úlceras por pressão acarretam elevados custos económicos associados ao tratamento, bem como custos intangíveis pelo sofrimento vivenciado por pessoas e cuidadores.

Validation of the potentially avoidable hospital readmission rate as a routine indicator of the quality of hospital care

BACKGROUND: The hospital readmission rate has been proposed as an important outcome indicator computable from routine statistics. However, most commonly used measures raise conceptual issues. OBJECTIVES: We sought to evaluate the usefulness of the computerized algorithm for identifying avoidable readmissions on the basis of minimum bias, criterion validity, and measurement precision. RESEARCH DESIGN AND SUBJECTS: A total of 131,809 hospitalizations of patients discharged alive from 49 hospitals were used to compare the predictive performance of risk adjustment methods. A subset of a random sample of 570 medical records of discharge/readmission pairs in 12 hospitals were reviewed to estimate the predictive value of the screening of potentially avoidable readmissions. MEASURES: Potentially avoidable readmissions, defined as readmissions related to a condition of the previous hospitalization and not expected as part of a program of care and occurring within 30 days after the previous discharge, were identified by a computerized algorithm. Unavoidable readmissions were considered as censored events. RESULTS: A total of 5.2% of hospitalizations were followed by a potentially avoidable readmission, 17% of them in a different hospital. The predictive value of the screen was 78%; 27% of screened readmissions were judged clearly avoidable. The correlation between the hospital rate of clearly avoidable readmission and all readmissions rate, potentially avoidable readmissions rate or the ratio of observed to expected readmissions were respectively 0.42, 0.56 and 0.66. Adjustment models using clinical information performed better. CONCLUSION: Adjusted rates of potentially avoidable readmissions are scientifically sound enough to warrant their inclusion in hospital quality surveillance.

Levantamento das espécies de Simulium (Diptera, Simuliidae), Riacho dos Padres, município de Almirante Tamandaré, Paraná, Brasil

De janeiro a agosto de 2002, quinzenalmente, foi levada a efeito a coleta de simulídeos imaturos em substratos naturais e antrópicos no Riacho dos Padres. O trabalho visou proceder ao inventário das espécies e verificar as freqüências relativas. A área de propriedade particular localizada na Região Metropolitana de Curitiba constitui uma microempresa de agronegócio, com criação de peixes, coelhos, ovinos, bovinos, aves domésticas e, ainda, área de lazer com eqüinos para cavalgada de visitantes. A presença constante de animais hospedeiros e a ração fornecida aos peixes garantiram farta alimentação aos simulídeos, o que favoreceu a explosão desta praga. Em todos os substratos foram coletadas 24.021 pupas e um total de 197.812 larvas. A partir de pupas, foram identificadas com as seguintes freqüências: Simulium inaequale (55,24%), Simulium perflavum (16,81%), Simulium pertinax (13,93%), Simulium orbitale (8,03%), Simulium subnigrum (4,92%), Simulium distinctum (1,03%) e Simulium incrustatum (0,04%). Verificou-se também a quantidade de larvas que colonizaram todos os substratos.

Melanin-based colouration predicts natal dispersal in the barn owl, Tyto alba

Searching for a suitable breeding site is an important decision in the life of most animals. The decisions where to settle and how far to travel before doing so depend on many factors. Individual differences in dispersal distance could result from different strategies (e.g. specialists versus generalists), which might result in similar reproductive success in different habitats, or different competitive abilities to acquire a territory close to the natal site. The barn owl is polymorphic in melanic coloration, which is associated with many physiological and behavioural traits such as habitat choice, stress response and docility, raising the possibility that the coloration is also related to dispersal. We studied natal dispersal (from rearing site to site of first breeding attempt) and breeding dispersal (from one breeding site to the next) in barn owls using a long-term data set. Darker reddish individuals moved further than paler individuals during natal dispersal, but not during breeding dispersal. A cross-fostering experiment showed that the colour of the biological and foster parents had no influence on dispersal distance. The distance dispersed by parents and same-sex offspring was correlated, whereas natal and breeding dispersal were not repeatable within individuals, indicating that they are two different processes. Given that the distance travelled in natal dispersal appears to be heritable, the underlying genes might be coupled to those related to coloration. We discuss hypotheses to explain the potential adaptive function of the link between coloration and natal dispersal.

Allergies aux produits de contraste radiologiques [Allergy to radiographic contrast media].

Allergy to radiographic contrast media Hypersensitivity reactions to radio-contrast media are common in the daily practice. These products are responsible for immediate (< or = 1 hour after administration) and non immediate (> 1 hour after administration) hypersensitivity reactions. A diagnostic work-up by an allergologist with skin tests and in some cases provocation tests is of value in reducing the risk of recurrent hypersensitivity reactions to iodinated contrast media. A careful selection of the patients is required because the incidence of breakthrough reactions is still concerning, even with proper premedication. Practical recommendations are presented in this article. For gadolinium-based contrast agents, data in the literature is not sufficient for suggesting guidelines.

Perception of the damaging effects of smoking, and brief cessation counselling by doctors.

An open prospective study was conducted among the patients visiting an urban medical policlinic for the first time without an appointment to assess whether the immigrants (who represent more than half of our patients) are aware of the health effects of smoking, whether the level of acculturation influences knowledge, and whether doctors give similar advice to Swiss and foreign smokers. 226 smokers, 105 Swiss (46.5%), and 121 foreign-born (53.5%), participated in the study. 32.2% (95% CI [24.4%; 41.1%]) of migrants and 9.6% [5.3%; 16.8%] of Swiss patients were not aware of negative effects of smoking. After adjustment for age, the multivariate model showed that the estimated odds of "ignorance of health effects of smoking" was higher for people lacking mastery of the local language compared with those mastering it (odds ratio (OR) = 7.5 [3.6; 15.8], p < 0.001), and higher for men (OR = 4.3 [1.9; 10.0], p < 0.001). Advice to stop smoking was given with similar frequency to immigrants (31.9% [24.2%; 40.8%] and Swiss patients (29.0% [21.0%; 38.5%]). Nonintegrated patients did not appear to receive less counselling than integrated patients (OR = 1.1 [0.6; 2.1], p = 0.812). We conclude that the level of knowledge among male immigrants not integrated or unable to speak the local language is lower than among integrated foreign-born and Swiss patients. Smoking cessation counselling by a doctor was only given to a minority of patients, but such counselling seemed irrespective of nationality.

Product market deregulation and the U.S. employment miracle

We consider the dynamic relationship between product market entry regulation and equilibrium unemployment. The main theoretical contribution is combining a job matchingmodel with monopolistic competition in the goods market and individual wage bargaining.Product market competition affects unemployment by two channels: the output expansion effect and a countervailing effect due to a hiring externality. Competition is then linked to barriers to entry. We calibrate the model to US data and perform a policy experiment to assess whether the decrease in trend unemployment during the 1980 s and 1990 s could be attributed to product market deregulation. Our quantitative analysis suggests that under individual bargaining, a decrease of less than two tenths of a percentage point of unemployment rates can be attributed to product market deregulation, a surprisingly small amount.
