Mechanical circulatory and/or respiratory assistance with extracorporeal membrane oxygenation (ECMO) has become a standard of care for patients with circulatory (venoarterial) and/or respiratory (venovenous) failure refractory to standard therapies. Adult patients with congenital heart disease are an increasingly recognized and growing population and include various groups, such as undiagnosed cases in childhood and palliated and/or corrected cases, which require subsequent care because of residual lesions, cardiac arrest/insufficiency, and arrhythmias, among other conditions. In addition, these patients are prone to developing pathologies that are typical of adulthood with a generally increased risk of morbidity and mortality because of their low reserves and organic damage associated with the underlying heart disease, which makes them candidates for ECMO. These patients represent an additional challenge in this therapy because malformations and the presence of a shunt can generally affect the usual cannulation methods and hemodynamic and oximetry monitoring. Thus, the configuration decision must be made on a case-by-case basis. Here, we present a cannulation method, venopulmonary artery ECMO, which provides hemodynamic and respiratory support, and may be ideal for patients with shunts and/or right ventricular dysfunction. To our knowledge, this is the first report of this configuration in patients with congenital heart diseases.

AIM: To verify the impairment of the hepatic lipid metabolism in prehepatic portal hypertension. METHODS: The concentrations of free fatty acids, diacylglycerol, triglycerides, and phospholipids were assayed by using D-[U-14C] glucose incorporation in the different lipid fractions and thin-layer chromatography and cholesterol was measured by spectrophotometry, in liver samples of Wistar rats with partial portal vein ligation at short- (1 mo) and long-term (1 year) (i.e. portal hypertensive rats) and the control rats. RESULTS: In the portal hypertensive rats, liver phospholipid synthesis significantly decreased (7.42 ± 0.50 vs 4.70 ± 0.44 nCi/g protein; P < 0.01) and was associated with an increased synthesis of free fatty acids (2.08 ± 0.14 vs 3.36 ± 0.33 nCi/g protein; P < 0.05), diacylglycerol (1.93 ± 0.2 vs 2.26 ± 0.28 nCi/g protein), triglycerides (2.40 ± 0.30 vs 4.49 ± 0.15 nCi/g protein) and cholesterol (24.28 ± 2.12 vs 57.66 ± 3.26 mg/g protein; P < 0.01). CONCLUSION: Prehepatic portal hypertension in rats impairs the liver lipid metabolism. This impairment consists in an increase in lipid deposits (triglycerides,diacylglycerol and cholesterol) in the liver, accompanied by a decrease in phospholipid synthesis.

BACKGROUND:Since we have previously shown an increase of mast cells in the small bowel and in the mesenteric lymph nodes in the rats with prehepatic portal hypertension,it can be hypothesized that this essential inflammatory cell would be involved in the pathogeny of the splanchnic changes related to portal hypertension. METHODS:To verify this hypothesis,we first studied mast cell infiltration in the ileum and in the mesenteric lymph nodes in sham-operated male Wistar rats(n=12) and in short-term prehepatic portal hypertensive rats (n=12),and the serum levels of rat mast cell protease Ⅱ(RMCP-Ⅱ)by *** a second set of experiments ketotifen,a mast cell stabilizer drug,was administered to sham-operated(n=10)and portal hypertensive(n=12) rats 24 hours before the intervention and prostanoids (PGE2,PGI2,TXB2)and leukotrienes(LTC4,LTB4)were assayed by RIA,mast cell infiltration in the ileum and in the mesenteric lymph nodes and the serum levels of RMCP-Ⅱwere also studied,to show its effectiveness to prevent the mesenteric alterations produced by the inflammatory mediators released by the mast cell. RESULTS:Forty-eight hours after the intervention RMCP-Ⅱ (P<0.05),PGE2(P<0.001)and LTC4 serum levels decreased and mast cell number and RMCP-Ⅱlevels increased in mesenteric lymph nodes in portal hypertensive *** administration of ketotifen reduced portal pressure(P<0.001),serum levels of PGE2(P<0.001)and RMCP-Ⅱ(P<0.001)in mesenteric lymph nodes. CONCLUSIONS:In acute portal hypertension in the rat,the mast cell translocation from intestinal mucosa to mesenteric lymph nodes,where they are activated and degranulates,would represent a defence mechanism to avoid the activation of an acute and massive inflammatory response in this *** administration of ketotifen is able to reduce the splanchnic inflammatory changes related to acute portal hypertension in the rat.

This paper aims to contribute to the prevention of natural disasters and generate a complement to other similar studies. The Popocatépetl volcano has showed significant and constant activity since 1994. The Colorada and Quimichule canyons are located within its geologic structure;due to their topographic features, ejected volcanic material and torrential rains in the past recent years, they put nearby communities at risk. This work presents a geostatistical analysis to obtain the gravity acceleration, slope by the distance-elevation relation, height-gravity and the fluid force on the canyons. The conversion of UTM to geographical coordinates was made with the use of the program Traninv applying the ITRF2008 epoch 2010.0 Datum and the 14 Zone;the local gravity was calculated with the use of International Organization of Legal Metrology (OIML) and the statistical analysis was obtained with the use of the Geostatistical Environmental Assessment. The structural modeling was performed using Surfer, and the spending and force were calculated using hydrological models. The correlation analysis concluded that Quimichule has the greatest gravity and that it would transport lahars faster. Mapping, geomorphological and statistical techniques and models were applied in accordance with the study to obtain the results presented here.
