BACKGROUND:Severe poisoning due to the overdosing of cardiac drugs can lead to cardiovascular *** order to decrease the mortality rate,the most severe patients should be transferred as quickly as possible to an extracorporeal membrane oxygenation(ECMO)***,the predictive factors showing the need for venous-arterial ECMO(VA-ECMO)had never been ***:A retrospective,descriptive,and single-center cohort *** consecutive patients admitted in the largest ICU of Reunion Island(Indian Ocean)between January 2013 and September 2018 for beta-blockers(BB),calcium channel blockers(CCB),renin-angiotensin-aldosterone system blockers,digoxin or anti-arrythmic intentional poisonings were *** implementation was the primary ***:A total of 49 consecutive admissions were *** patients had ECMO,39 patients did not have *** patients in ECMO group died,while no patients in the conventional group *** most relevant ECMO-associated factors were pulse pressure and heart rate at first medical contact and pulse pressure,heart rate,arterial lactate concentration,liver enzymes and left ventricular ejection fraction(LVEF)at *** pulse pressure at first medical contact and LVEF were significant after logistic ***:A transfer to an ECMO center should be considered for a pulse pressure<35 mmHg at first medical contact or LVEF<20%on admission to ICU.

Specific heat(Cp)and effective thermal conductivity(λ)of native maize starch(NS)were measured by DSC and transient heat transfer method,respectively,at different moisture contents and *** dependency of temperature(T)and moisture content(W)on the two parameters were *** thermophysical properties of treated starch(TS)by four hydrothermal processes(RP-HMT,IV-HMT,DV-HMT and FV-HMT)were measured and compared to native *** treatments were performed at 3 bars(133°C)for 10 *** Cp andλmeasurements,moisture content varied for NS from 5 to 21.5%*** from 8.8 to 25%d.b.,respectively,and was fixed at 6%*** *** models were developed to specific heat and effective thermal conductivity,using a multiple regression algorithm with subsequent statistical *** proposed models for NS based on T and W predict Cp andλwith a mean absolute error of 3.5%and 1.3%,*** differences in specific heat were observed between TS and *** a temperature range of 40 to 160°C,Cp values varied from 1.964 to 2.699 for NS and 1.380 to 2.085(J.g-1.°C-1)for *** contrast,the conductivity of NS was almost identical to that of treated starch by FV-HMT,followed in an increasing order by those treated by DV-HMT,RP-HMT,and IV-HM processes.
