Arquivos Brasileiros de Cardiologia , 2012, DOI: 10.1590/S0066-782X2012005000060
Abstract: background: the combined use of antithrombotic agents, antiplatelet agents and invasive strategies in acute coronary syndrome without st-segment elevation (acswste) reduces cardiovascular events. fondaparinux has demonstrated equivalence to enoxaparin in reducing cardiovascular events, but with a lower rate of bleeding in patients using fondaparinux. objective: evaluate the cost-effectiveness of fondaparinux versus enoxaparin in patients with acswste in brazil from the economic perspective of the brazilian unified health system (sus). methods: a decision analytic model was constructed to calculate the costs and consequences of the compared treatments. the model parameters were obtained from the oasis-5 study (n = 20,078 patients with acswste randomized to fondaparinux or enoxaparin). the target outcome consisted of cardiovascular events (i.e., death, myocardial infarction, refractory ischemia and major bleeding) on days 9, 30 and 180 after acswste. we evaluated all direct costs of treatment and acswste-related events. the year of the analysis was 2010 and the costs were described in reais (r$). results: on day 9, the cost of treatment per patient was r$ 2,768 for fondaparinux and r$ 2,852 for enoxaparin. approximately 80% of total costs were associated with invasive treatments. the drug costs accounted for 10% of the total cost. the combined rates of cardiovascular events and major bleeding were 7.3% and 9.0% for fondaparinux and enoxaparin, respectively. sensitivity analyses confirmed the initial results of the model. conclusion: the use of fondaparinux for the treatment of patients with acswste is superior to that of enoxaparin in terms of prevention of further cardiovascular events at lower cost.

Abstract: background and objectives: studies show the importance of monitoring neuromuscular function in preventing the residual block. however, most anesthesiologists in their daily practice base their evaluation of the recovery of neuromuscular function on clinical data. the aim of this study was to assess the degree of neuromuscular blockade in children undergoing general anesthesia at the time of block reversal and the removal of the endotracheal tube. method: we evaluated children between 3 months and 12 years of age undergoing general anesthesia with the use of atracurium or rocuronium. monitoring was initiated at the time of reversal of neuromuscular blockade and/or removal of the endotracheal tube. the anesthesiologist was not informed about the t4/t1 value; he/she was only alerted when the time was inadequate for the removal of the endotracheal tube. since the start of the monitoring process, the degree of neuromuscular blockade was registered, as well as the interval of recovery of the t4/t1 > 0,9 ratio, the doses of neostigmine and blocker used, the expired fraction of the inhalational agent, the duration of the anesthesia, and core and peripheral temperatures. results: neuromuscular blockade was reversed in 80% of the children of the rocuronium group and in 64.5% of the atracurium group. the reversal was incorrect in 45.8% of the rocuronium group and in 25% of the atracurium group. the incidence of t4/t1 < 0.9 at the time of the removal of the endotracheal tube was 10% in both groups. conclusions: when deciding to remove the endotracheal tube based on clinical criteria, 10% of children had t4/t1 < 0.9 regardless the blocker received. a considerable number of patients had the neuromuscular blockade incorrectly reversed when the blockade was still too deep or even already recovered.

Abstract: several studies have demonstrated that regular physical activity improves diabetes conditions, favoring the peripheral glucose uptake, glycogen and protein metabolism. however, the effects of high intensity physical training on the immune system of diabetic organisms are not totally clear. the aim of this study was to verify the effects of high intensity physical training on the total and differential leukocyte count of diabetic rats. male young wistar rats were distributed into four groups: sedentary control (sc), trained control (tc), sedentary diabetic (sd) and trained diabetic (td). diabetes was induced by alloxan (30 mg/kg body weight i.v.). during six weeks the animals of tc and td groups followed a high intensity physical training protocol which consisted of four sets of 10 jumps/day (interrupted by one minute of rest interval) in a swimming pool, with the water level corresponding to 150% of the body length and overload equivalent to 50% of the body weight. at the end of the experimental period, blood samples were collected for total and differential leukocyte count. the results were analyzed by anova at a significance level of 5%. serum glucose was increased in diabetic groups while the insulin level was reduced in these groups. there were no significant differences in lymphocytes, neutrophils, and eosinophils, and in total leukocyte count when the groups were compared. monocytes count was higher in both trained groups (sc = 10.0 ± 4.5, tc* = 25.4 ± 7.9, sd = 19.75 ± 7.4, td* = 25.8 ± 4.4%). the relative weight of the thymus was reduced by diabetes and training (sc = 125.0 ± 37.7, tc* =74.6 ± 8.2, sd* = 47.5 ± 12.2, td* = 40.1 ± 16.9). in conclusion, the high intensity physical training protocol did not change the general diabetes conditions, but improved relative monocytes. these results can represent a positive effect on the immune response.

Abstract: Estudos têm demonstrado que o exercício físico regular melhora as condi es do diabetes, facilitando a capta o periférica da glicose e o metabolismo de glicogênio, proteínas, etc. Por outro lado, pouco se conhece sobre os efeitos do exercício intenso em diabéticos, principalmente com rela o ao sistema imune desses organismos. O presente estudo teve como objetivo verificar os efeitos de um treinamento físico de alta intensidade sobre a contagem total e diferencial de leucócitos em ratos diabéticos. Ratos machos jovens Wistar foram distribuídos em quatro grupos: controle sedentário (CS), controle treinado (CT), diabético sedentário (DS) e diabético treinado (DT). O diabetes foi induzido por aloxana (35mg/kg de peso corporal). Durante seis semanas os animais dos grupos CT e DT realizaram um protocolo de treinamento físico, que consistiu na realiza o de quatro séries de 10 saltos (intercaladas por um minuto de intervalo) em piscina, com o nível da água correspondendo a 150% do comprimento corporal e sobrecarga equivalente a 50% da massa corporal dos animais. Ao final do período experimental, amostras de sangue foram coletadas para a contagem total e diferencial dos leucócitos. Os resultados foram avaliados estatisticamente por ANOVA com um nível de significancia de 5%. A glicemia foi aumentada entre os diabéticos e a insulinemia diminuída. N o foram observadas diferen as significativas na contagem diferencial dos linfócitos, neutrófilos, eosinófilos e contagem total de leucócitos entre os grupos estudados. Houve aumento dos monócitos entre os treinados (CS = 10,0 ± 4,5, CT* = 25,4 ± 7,9, DS = 19,75 ± 7,4, DT* = 25,8 ± 4,4%). O peso relativo do timo foi reduzido pelo treinamento e pelo diabetes (CS = 125,0 ± 37,7, CT* = 74,6 ± 8,2, DS* = 47,5 ± 12,2, DT* = 40,1 ± 16,9mg/100g). Esses resultados permitem concluir que o treinamento físico de alta intensidade n o alterou o estado geral do diabetes, mas aumentou os monócitos, o que pode representar um efeito positivo sobre a resposta imunológica desses animais.

Abstract: The objective of the present study was to verify the effects of two frequencies (100 and 33%) of knowledge of results (KR) on the learning of a motor skill, in individuals with Down syndrome (DS). Twenty participants with DS were randomly assigned into two groups. While the 100% group received KR after each trials, the 33% group received KR in a third of the trials. The task consisted of throwing an implement on a target, with the dominant hand, while blindfolded. The acquisition phase consisted of 30 practice trials, while the retention phase, performed after 48 hours later, consisted of 10 trials without KR. The results showed no differences between the groups. We concluded that reduced relative frequencies of KR are as effective as high frequencies on the learning of simple motor tasks in adults with DS.

OBJECTIVES: The purpose of the present study was to examine whether the learning benefits of self-controlled feedback found previously in non-disabled adults would also be found in adults with Down syndrome. METHODS: Participants with Down syndrome practiced a linear positioning task. In the self-control group, learners were provided with feedback about the movement outcome at their request. Each participant in the yoked group received the same feedback schedule as their counterpart in the self-control group. RESULTS: Learning was assessed by a retention test, consisting of 10 trials without feedback, one day later. The self-control group demonstrated more effective learning of the task than the yoked group. CONCLUSION: Self-controlled feedback enhanced motor learning in participants with Down syndrome. CONTEXTUALIZA O: Uma variável que consistentemente tem mostrado melhorar a aprendizagem em sujeitos típicos é a prática autocontrolada. OBJETIVOS: Examinar se os benefícios do feedback autocontrolado para a aprendizagem, encontrados previamente em adultos típicos, também ser o encontrados em adultos que apresentam a Síndrome de Down. MéTODOS: Participantes com a Síndrome de Down praticaram uma tarefa de posicionamento linear. Os aprendizes do grupo autocontrolado receberam feedback sobre o resultado do movimento, quando solicitado. Já os participantes do grupo pareado receberam o mesmo arranjo de feedback dos sujeitos do grupo autocontrolado. RESULTADOS: A aprendizagem foi avaliada por meio de um teste de reten o, o qual consistiu em dez tentativas sem feedback, um dia depois da fase de prática. O grupo autocontrolado demonstrou aprendizagem mais efetiva da tarefa do que o grupo pareado. CONCLUS O: Feedback autocontrolado melhora a aprendizagem motora em sujeitos com a Síndrome de Down.

Abstract: It aimed to analyze the assistance to the blind woman during prenatal care, childbirth, and child-care in light of the Model of Attention to Chronic Conditions. This is a descriptive, qualitative study. A collection was done through semi-structured interview and analysis of the speeches, conducted by content technique proposed by Bardin, emerging from the screening process. Ten mothers aged between 21 and 42 years old participated in the study. Three categories were identified: prescriptive and focused attention on the disease; for collaborative and focused attention on the person; uniprofessional attention to the multidisciplinary attention; establishment of relationship between the family health strategy and the specialized outpatient care. The women experienced chronic conditions according to the Model in addition to blindness. Study results show that for blind women, attention in the health service has weaknesses in service, both in the prenatal period and childbirth, and in childcare. It deems necessary transformation in assisting the blind woman.

Abstract: O processo de avalia o de empresas é fortemente praticado e discutido por teóricos e investidores no mercado de capitais. A mensura o da taxa de investimento é uma das etapas relevantes nesse processo, visto que as empresas buscam maximizar o seu valor de mercado a partir de elevados retornos sobre suas decis es de investimento. Este trabalho tem como objetivo central verificar se no Brasil existe aderência entre a teoria e as práticas do mercado no que tange ao processo de estima o dos investimentos em capital fixo e de giro e da taxa de investimento. A pesquisa também traz uma análise entre a aderência das proje es de investimentos nos laudos de avalia o de empresas e o que foi realizado nas demonstra es contábeis publicadas. Quanto aos métodos adotados, com o intuito de atingir o propósito desta pesquisa, optou-se por um estudo descritivo e uma pesquisa quantitativa, nos quais foi aplicado o teste de diferen a de médias. Para verificar a teoria, utilizou-se como fonte bibliográfica a contribui o de diversos autores sobre o assunto. Foi realizada uma revis o bibliográfica a partir de livros, artigos e sites específicos. Para verificar a prática do mercado brasileiro, realizou-se uma pesquisa documental através da investiga o dos laudos de avalia o das companhias, os quais s o apresentados como requisito às ofertas públicas de aquisi o de a es (OPA) e estavam disponíveis no site da Comiss o de Valores Mobiliários (CVM). Para a análise de aderência entre as proje es e o realizado, foram utilizados os dados coletados na economática. Duas amostras foram verificadas, e, a partir dos testes realizados, pode-se verificar a contribui o e a credibilidade das informa es geradas pelas avalia es de empresas no Brasil.
