Fatores pré-operatórios associados à injúria renal aguda após cirurgia cardíaca: estudo prospectivo

OBJECTIVES. To evaluate the clinical characteristics and co-morbidities associated with development of Acute kidney injury (AKI) after cardiac surgery in patients of a predominantly tertiary care university hospital.METHODS. One hundred and fifty cardiac surgery patients were prospectively studied at the Botucatu School of Medicine, University Hospital- UNEP, using a protocol which started 48h before and finished 48h after surgery, AKI was defined as a 30% increase in baseline serum creatinine.RESULTS. Were expressed as mean +/- standard deviation or median, with a significance level of 5%. Results: There was a slight male predominance (57%); mean age of the studied population, was 56 +/- 14 years. Sixty-five per cent of patients underwent myocardial revascularization. AKI was diagnosed in 34% of cases, Multivariate analysis showed that age over 60 years and peripheral vascular disease were significant associated with AKI developmentCONCLUSION. AKI was a common complication in cardiac surgery patients at this hospital, AKI was associated with age over 60 years and presence of peripheral vascular disease.

Endectocide activity of a pour-on formulation containing 1.5 per cent ivermectin +0.5 per cent abamectin in cattle

The present work aimed to evaluate, through ten different studies, the therapeutic efficacy of a new pour-on formulation, containing 1.5 per cent ivermectin +0.5 per cent abamectin, against parasites of cattle. Results obtained on trials against Rhipicephalus (Boophilus) microplus showed that the pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained superior efficacy indexes against this ectoparasite, when compared with formulations containing 0.5 per cent ivermectin, 1 per cent ivermectin and the combination of 1 per cent abamectin +20 per cent levamisole. The results of efficacy of the ivermectin+abamectin and the 0.5 per cent ivermectin against Haematobia irritans were similar. Against Cochliomyia hominivorax larvae, all pour-on formulations tested (1.5 per cent ivermectin +0.5 per cent abamectin, 0.5 per cent ivermectin and 0.5 per cent abamectin), as well as 1 per cent doramectin administered subcutaneously, were considered ineffective. Cattle medicated with 1.5 per cent ivermectin +0.5 per cent abamectin, pour-on, remained free from parasitism by Dermatobia hominis larvae during 42 days (96 per cent efficacy), while values superior to 90 per cent were obtained by 0.5 per cent ivermectin (92 per cent) and 0.5 per cent abamectin (93 per cent) until the 42nd and 35th days post treatment, respectively. Against Haemonchus placei and Oesophagostomum radiatum, the pour-on of ivermectin+abamectin showed better efficacy than the 0.5 per cent ivermectin and 0.5 per cent abamectin. As to Cooperia punctata, there was no difference regarding efficacy results obtained by the avermectins combination and abamectin. The pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained high efficacy against R. (B.) microplus, D. hominis and some species of cattle gastrointestinal helminths when compared with formulations of 0.5 per cent ivermectin and 0.5 per cent abamectin administered through the same route.
