BACKGROUND:Obstructive jaundice is a common condition in advanced digestive *** procedures can improve quality of life and allow patients to attempt a systemic *** anastomosis is still the procedure of choice for patients in many *** a surgical bypass is not possible,biliary drainage can be done by placing endoscopic or transparietal stents,which are less durable methods even when an expandable stent is employed. METHODS:A 47-year-old male with an excellent clinical status and a previous cholecystectomy and an exploratory laparotomy for advanced gastric cancer was referred with obstructive jaundice.A preoperative CT scan showed a dilated bile duct and a small mass at the distal hepatic *** other signs of metastasis were found.A surgical bilioenteric anastomosis was *** surgery,a distal choledochal obstruction and a mesenteric retraction by a lymph node mass prevented the jejunum to ascend for a bilioenteric anastomosis. Surgically,an alternative bilioenteric bypass was performed by means of an ileal loop interposition between the bile duct and the jejunum. RESULT:The recovery of the patient was uneventful and his bilirubin levels normalized after one *** patient was then referred for systemic chemotherapy. CONCLUSIONS:This alternative biliary bypass can be safely and easily performed,and may be a good alternative for patients already referred for surgery because of a better life expectancy and when the jejunum is not an alternative.

Background Hypertension is the main risk factor for cardiovascular diseases, affecting more than half the elderly population. It is essential to know if they have proper control of hypertension. The aim of this study was to identify the associated factors to masked uncon- trolled hypertension and false uncontrolled hypertension in older patients. Methods Two-hundred seventy-three individuals （70.1±6.7 years-old） had blood pressure （BP） measured at the office and by ambulatory BP monitoring （ABPM）, with the definition of controlled group （C）, individuals with high office BP and adequate ABPM, called white-coat effect group （WCE）, uncontrolled （UC）, and subjects with ap- propriate office BP and elevated ABPM denominated masked effect group （ME）. Age, body mass index, diabetes, pulse pressure （PP） and BP dipping during sleep were evaluated （Kruskal-Wallis test and logistic regression models）. Results Age was higher in UC than in C and ME （P 〈 0.01）, and 24-h ABPM PP was lower in C （48± 7 mmHg） and WCE （51±6 mmHg） than in UC （67±12 mmHg） and ME （59±8 mmHg）（P 〈 0.01）. Sleep systolic BP dipping was lower in ME than in C （P = 0.03）. Female gender was associated with a greater chance of being of ME group, which showed a higher PP and lower BP dipping during sleep. Conclusions In older individuals, office BP measure- ments did not allow the detection of associated factors that would permit to differentiate WCE from UC group and C from ME group. ABPM favored the identification of a higher PP and a lower BP dipping during sleep in the masked effect and uncontrolled groups.

Journal of Civil Engineering and Architecture 2014年第1期8卷 11-18页

作者： Paulo Roberto Aguiar Cassio eduardo lima de Paiva Geotechnical and Transportation Department Civil Engineering School Campinas University (UN1CAMP) Campinas 13000-000Brazil

The current study is developed based on one of the types of subgrade rupture risk suggested by Selig and Waters （1994）. It aims to evaluate subgrade stability railroad, which consists of the slope stability analysis of a railway yard embankment subjected to a wagon load type gondola parked on this track. This proposed analysis was taken into consideration because there are Brazilian railroads in high deterioration level. In some of these lines the tracks are submitted to increasing amount of load every year. The adopted model slope stability to the studied railroad embankments considers the rupture on circular line. It was applied the Geoslope-Slope/W software, version 6, to the evaluation of the platform-slope system. Several situations are adopted to reach the minimum safety slope, permitting to analyze the platform stability to keep railroad traffic under adequate safety level.

Studying the interaction of components is basic for a railroad project, which is also very important for creating maintenance procedures based on predictions from a model that assumes adequate performance. To determine these interactions, which can have a great number of combinations, the use of a computational model is of vital importance, in this case, the program FERROVIA 1.0 （RAILROAD 1.0） was used. A critical study developed the program FERROVIA 1.0, and its variables were characterized based on values observed in the literature. After initial characterization was carried out, a comparative study was performed on the sensitivity between these variables and the indications of significant behavior for a railway deformed by the known load of a wheel. A statistical program was used to correlate the elements. The intention was to launch the program FERROVIA 1.0 and later use it for 2,187 combinations. The data used in these correlations corresponded to the normal values for the elements used in railroad engineering practice. Our main goal is to understand the behavior of the track vertical deflection according to the variation of the scaling of the various elements of the railway,

The aims of this study were:i)to compare no-till areas in two municipalities located in different regions of Brazil,along with the influence on CO_(2)Flux and GPP,and ii)to verify the difference between environmental factors followed by the trends of these variables regarding future scenarios(ARIMA time-series model number).The study was carried out in two areas with different latitudes in the municipalities of Sinop-MT and Passo Fundo-RS,both in Brazil.A time series of 19 years was performed with data acquired by remote sensing from the following satellites:i)Landsat-8(OLI and TIRS),and ii)TERRA/AQUA(MODIS).The results propound that the spectro-temporal variables are directly influenced by soil management and agricultural practices over the observation time,with a satisfactory correlation in future predictions of the variables for the next ten years,in which presented that the variation of GPP and albedo values for the two study sites would gradually increase until 2028 and the temperature remained constant between the range of its seasonality,and CO_(2)Flux tends to decrease in its seasonality,indicating a higher CO_(2) absorption.

Literature in finance and neurosciences shows that male and female differ in many relevant issues concerning financial decision investment. Here, we studied the EEG activity recorded while volunteers were playing a stock trading game to investigate these gender differences. 20 males and 20 females made 100 trading decisions using a portfolio of 200 shares of 7 different companies. Males and females were equally successful in earning above the market. sLORETA was used to identify sources of EEG recorded 2 seconds before trading decision. Results showed that male and female used different sets of neuron to make equally successful financial decisions.
