Abstract Background: Hospital accreditation has as goal the standardization of patient care, aiming quality improvement. On 2015, a cardiology reference hospital was evaluated and got level 3 from ONA in care given to Acute Coronary Syndrome (ACS) patients. Objetive: To compare length of stay (LOS) at Coronary Care Unit (CCU) and the total LOS at the hospital of ACS patients before and after ONA 3 accreditation. Other clinical outcomes were also analyzed. Methods: Systematic and prospective registry of admitted ACS patients at CCU, whose population was divided into pre-accreditation (period 1) and post-accreditation (period 2). Descriptive analysis was performed. For statistical analysis the Mann-Whitney test, chi-squared, Fisher’s exact test and Multiple Linear Regression were performed. P value was considered statistically significant when < 0,05. Results: 372 patients were admitted with ACS, 186 in period 1, of which 47 (25,3%) with ST segment Elevation Myocardial Infarction (STEMI), and 186 in period 2, of which 70 (37,6%) with STEMI. The mean age was 65,9 years (± 12,2). About the CCU LOS, there was a reduction from 3 (IQR: 2-4) to 2,5 days (IQR: 2-4; p value = 0,088). Regarding the hospital LOS, there was also a reduction from 8 (IQR: 5-12,25) to 6 days (IQR:4-11; p value = 0,004). Analyzing the type of ACS, there was a significant reduction only at the hospital LOS in non-STEMI patients: 8 to 6 days (p value = 0,001). Other hospitalization length of stay and clinical outcomes did not present a significant reduction in the comparison. Conclusion: After the ONA 3 accreditation, there was a reduction of hospital LOS. There were no significant differences in the other outcomes analyzed.

RESUMO O tratamento da doença arterial coronariana estável (DAC) se baseia na melhora do prognóstico e alívio de sintomas. Diretrizes nacionais e internacionais sobre a DAC respaldam a indicação de revascularização em pacientes com sintomas limitantes e refratários ao tratamento medicamentoso, bem como em situações clínicas nas quais há benefício prognóstico do tratamento intervencionista. Grande parte dos estudos que norteiam as diretrizes de indicação de revascularização data das décadas de 1980 e 1990. Estudos recentes têm revisitado o tema e trazido novo fôlego. A presente revisão faz uma análise crítica das indicações clássicas de revascularização, revisando a evidência desde os estudos da década de 1970 ao recente e polêmico estudo Orbita.

SUMMARY Treatment of stable coronary artery disease (CAD) relies on improved prognosis and relief of symptoms. National and international guidelines on CAD support the indication of revascularization in patients with limiting symptoms and refractory to optimal medical treatment, as well as in clinical situations where there is a prognostic benefit of interventional treatment. Most of the studies that support the guidelines for indication of revascularization date back to the 1980s and1990s of the last century. Recent studies have revisited the theme and brought a new breath. The present review provides a critical analysis of classic indications for revascularization, reviewing evidence from the studies of the 1970s to the recent controversial ORBITA study.

This study aimed at evaluating the effect of ractopamine (RAC) on metabolism, zootechnical performance, body composition, and behavior in Wistar rats submitted to acute and chronic restrain stress. The oral dose of 5 mg/kg of RAC was administered in periods of 0, 7, 14, 21, and 28 days. The elevated plus-maze test (EPMT) was used for behavioral assessment. Blood, carcass and viscera characteristics were evaluated. Insulin-dependent glucose transporters (GLUT-4) were semi-quantified by Western Blot in epididymal adipocytes. RAC periods associated with chronic stress increased the GLUT-4 protein expression in adipose tissue in a time-dependent manner (P=0.01), i.e., the longer the RAC addition period, the higher the GLUT-4 concentration in chronically stressed animals (0=1.42; 7=1.19; 14=2.03; 21=1.59; 28=2.35). The stress periods combined with RAC increased the time spent in the opened arms of the maze (Chronic stress: 0=10.6; 7=8.7; 14=5.9; 21=12.3; 28=4.0; Acute stress 0=3.1; 7= 4.7; 14=7.5; 21=0.0; 28=2.8) (P=0.04). Chronic (entries on the closed arms [ECA]=3.60) and acute (ECA=3.80) stress reduced locomotive activity in the maze (P=0.03). The results suggested that stress could negatively affect the possible benefits offered by the RAC, mainly impairing the adipose tissue metabolism and behavior in the animals.

Este trabalho foi desenvolvido com o objetivo de investigar o perfil do pH durante o processo de degomagem de grãos de café utilizando diferentes procedimentos de manejo. O estudo foi realizado em propriedades cafeeiras da Região Sudoeste da Bahia, utilizando a variedade Catuaí Amarelo. Foi utilizado o delineamento experimental inteiramente casualizado em esquema fatorial 2 x 2 x 6, sendo dois manejos da água (com e sem troca de água do meio), dois manejos do meio degomante (com e sem revolvimento do meio), seis tempos (0, 6, 12, 18, 24, 30 horas) com três repetições. Nos tratamentos em que houve a troca de água do tanque, o revolvimento do meio degomante causou redução nos valores do pH, embora essa redução tenha sido significativa apenas nas propriedades 2 e 3. Nos tratamentos em que não foi feito o revolvimento do meio observou-se que os valores do pH do meio degomante nas propriedades 1 e 2 não reduziram significativamente após 12 horas, tanto para o tratamento em que foi realizada a troca de água do tanque, quanto para aquele cuja troca de água não foi feita. Entretanto, na propriedade 3 foi observada uma redução no pH do meio de degomagem até 24 horas; no fim do processo esta redução foi mais acentuada para o tratamento em que não houve a troca de água do tanque.

The objective of this work was carried out with to investigate the profile of the pH during the coffee degumming process under different handling procedures. The study was done in coffee farms in the Southwest Region of Bahia State, Brazil, on July and August 2005, using the species Coffea arabica L., Catuai Amarelo. A randomized entirely experimental design was adopted, with three repetitions, in factorial outline 2x2x6 (with and without change of water of the medium degumming, with and without revolving of the medium degumming, in six time periods). In the treatments in which there was change of water of the drum (vessel) the revolving of the medium degumming caused a reduction in the values of pH, though this reduction was significant in farms 2 and 3. In treatments in which was not made the revolving of the medium, it was observed that the pH values of the medium degumming in farms 1 and 2 did not reduce significantly from 12 hours, as for the treatment in which was done the change of water of the drum, as in which the change of water was not done. However, in farm 3, it was observed a reduction in the medium pH until 24 hours, however in the end of the process this reduction was more pronounced in the treatment which there was no change of water of the drum.

Este trabalho foi realizado com o objetivo de avaliar a utilização da variável condutividade elétrica do meio desgomante como um indicador dos procedimentos de manejo do café despolpado durante a desgomagem do grão. Os experimentos foram conduzidos em três propriedades cafeeiras da região sudoeste da Bahia, utilizando Coffea arabica L., variedade Catuai Amarelo, para estudar o efeito de dois manejos de água do meio desgomante, dois manejos de revolvimento da solução desgomante e seis períodos de tempo em esquema fatorial. Um aumento da condutividade elétrica foi observado durante a desgomagem do grão, principalmente, no tratamento com revolvimento do meio. A troca de água do meio desgomante mostrou ser necessária, pois, ao longo da desgomagem, ocorreu um equilíbrio eletroquímico no meio, impedindo que a mucilagem continuasse a ser liberada do grão para o meio. Portanto, por meio da condutividade elétrica do meio, é possível indicar o momento em que se deve realizar a troca de água do tanque de desgomagem.

This research was carried out with the aim to evaluate the use of electric conductivity of the degumming medium as an indicator for management procedures of depulped coffee during degummming of the grain. The experiment was performed in three coffee properties in the Southwest region of Bahia, Brazil, using Coffea arabica L., Yellow Catuai variety. It was studied the effect of two water management of the degumming medium, two management of rummaging of the degumming solution, six time periods in factorial design. An increase on the electrical conductivity values was observed during degumming of coffee grain. Mainly in the treatment where the medium was rummaged. The water change of the degumming medium showed to be necessary since along the degumming process an electro-chemical equilibrium of the medium was achieved, avoiding that the mucilage was liberated from the grain to the medium. Therefore, the electrical conductivity was possible to indicate when the water change from the degumming tank must be done.
