Postoperative Heparin-Mediated Extracorporeal Low-Density Lipoprotein Fibrinogen Precipitation Aphaeresis Prevents Early Graft Occlusion after Coronary Artery Bypass Grafting

Background Early graft occlusion due to thromboembolic events is a well-known complication after coronary artery bypass grafting (CABG). Fibrinogen, the coagulation factor I, is a glycoprotein that is transformed by thrombin into fibrin. It plays amajor role in thrombus formation and is highly elevated after CABG. Our aim was to determine if postoperative lowering of fibrinogen levels by H.E.L.P. (heparin-mediated extracorporeal low-density lipoprotein [LDL] fibrinogen precipitation) aphaeresis could reduce the rate of early graft occlusion in patients with hypercholesterolemia undergoing CABG. Methods Between December 2004 and September 2009, 36 male patients with hypercholesterolemia (mean LDL cholesterol 128 +/- 12 mg/dL), mean age 58 +/- 9 years, underwent CABG. Mean preoperative fibrinogen level was 387 +/- 17 mg/dL. H.E.L.P. aphaeresis was postoperatively performed when fibrinogen levels exceeded 350 mg/dL on day 1 and 250 mg/dL every consecutive day up to day 8. Pre- and postaphaeresis blood samples were obtained and plasma fibrinogen level reduction was calculated. Early graft occlusion was evaluated by means of coronary angiography or multislice computed tomography before discharge. Results A total of 128 distal anastomoses were performed in 36 patients (mean 3.6/patient). Postoperatively, 191 H.E.L.P. aphaeresis sessions were performed (mean 5.3/patient). Fibrinogen levels were lowered from 391 +/- 10 mg/dL (preaphaeresis) to 171 +/- 5 mg/dL (postaphaeresis;p < 0.001). Coronary angiography (multislice computed tomography in 7 patients) revealed graft patency in 125 of 128 grafts (98% patency) with three occluded venous grafts to target vessels of 1.5 mm. H.E.L.P. aphaeresis-related complications were limited to hypotensive episodes in two patients and bacteremia in one patient. Conclusions H.E.L.P. apheresis offers an easy, save, and efficient method to decrease fibrinogen postoperatively in patients having CABG. Showing excellent graft patency rates in comparison to the literature, this method is a promising tool to reduce early graft occlusion after CABG

Avaliação de ionóforos pela técnica da perda do potássio celular e produção de gases in vitro.

Dois estudos foram realizados com vacas lactantes utilizadas como unidade experimental e doadoras de líquido ruminal, sendo as populações de bactérias utilizadas para avaliar a ação de níveis crescentes de lasalocida e monensina na resistência à perda de potássio intracelular, e para produção de gases in vitro. A perda de potássio (Kmax) da lasalocida foi menor para a população de bactérias obtidas do líquido de rúmen de vacas submetidas a dietas com monensina, óleo de soja e monensina mais óleo de soja (19,4 a 25,4%) quando comparada com a perda de potássio em vacas submetidas a dietas sem ionóforo e óleo de soja (30,1%). O mesmo ocorreu para a perda de potássio da monensina, em que o menor valor foi de 6,5% para monensina mais óleo e o maior, de 29,5%, para o controle. Necessita-se de alta concentração de monensina (Kd= 2,3µM), porém baixa de lasalocida (Kd= 0,2µM) para causar a metade da perda máxima de potássio intracelular da população de bactérias do rúmen de vacas submetidas a dietas com monensina. As populações de bactérias de vacas submetidas às dietas com monensina foram sensíveis à lasalocida. As amostras incubadas com própolis produziram menor volume de gases (12,9ml/100g de MS)

Correlation between residual feed intake and daily water intake in confined nellore bulls.

Identifying efficient animals is an alternative to reduce food costs and natural resources used in farming. The objective of this study was to identify the correlation between Residual Feed intake (RFI) and Daily Water Consumption (DWC) in Nellore cattle. The work was realized at Núcleo Regional of Embrapa Cerrados, in June, 2017. Were used 44 bulls, aged between 18 and 21 months and initial weight of 455 kg. The diet was given twice daily, with corn silage: concentrate of 60:40. Feed intake was obtained in the feeders of Intergado System. Daily water consumption was measured by water drinked in electronic drinking fountains coupled to the automatic scales (Intergado System TM) plus water from feed. The RFI was calculated by means of the difference between the observed dry matter intake (DMIobs) and the expected dry matter intake (DMIexp) based on live weight (LW) and average daily gain (ADG). The descriptive statistics, comparison of means by Tukey test at 5% probability and Pearson correlations for the study traits were performed using software R (version 3.3.2). Groups of high, low and mean RFI were formed with one Standar Desviation of the mean RFI. The water consumption averaged 38.9 L / day, with a standard deviation of 6.1 L / d, and a minimum value of 30.0 and a maximum of 62.2 L / day. The RFI had zero and standard deviation of 1.01 kg / d, with a minimum value of -2.38 and a maximum of 2.7. The correlation between RFI and DWC was .24, being considered of low magnitude. It was not observed differences between RFI groups, with means of 37.0, 38.8 and 42.3 L / d, respectively, to Low, Medium and High RFI Groups. We concluded that water intake was not correlated with RFI in Nellore bulls confined in the early dry season of Brazil
