Fifteen species of metazoan parasites were collected. Paralonchurus brasiliensis is a new host record for 13 parasite species. The majority of fishes were parasitized by one or more metazoan. Larvae of Contracaecum sp. proved to be the dominant species, with highest prevalence and abundance values. The parasite species of P. brasiliensis showed the typical aggregated distribution pattern. Prevalence and abundance of Procamallanus (Spirocamallanus) pereirai was positively correlated with the host total length. Abundance of Contracaecum sp. was positively correlated with the host total length. The abundances of a pair of adult endoparasites (Aponurus laguncula-Procamallanus (S.) pereirai) showed negative covariation and one pair of larvae stages of endoparasites (Nybelinia sp.-Contracaecum sp.) showed positive covariations between their abundances. Paralonchurus brasiliensis showed a metazoan parasite community composed by generalist species, little ordered and with scarce quantitative evidences of interspecific associations. These patterns agree with those detected in preceding studies about the parasite communities of Neotropical sciaenid fishes.

Methods-A retrospective study based on medical records of 388 patients hospitalized with an AMI in different hospitals between January 1993 and December 1994. The relative risk (RR) was used as a measure of association for the unadjusted analysis. To control for possible confoundears and to assess interactions, odds ratios (OR) were used to estimate the RR, by logistic regression models. Results-During the hospitalization period 50 (12,9%) patients died. The main predictors of hospital mortality in the unadjusted comparisons were older age (age >60 years) (RR=2.76; p<0.01), female gender (RR=2.08; p=0.01), Killip class >1 (RR=5.73; p<0.01), anterior wall AMI (RR=1.92; p=0.02), previous stroke (RR=4.13; p<0.01) and systemic disease (RR=2.76; p<0.01). In the multivariate analysis, older age (OR=2.42; p=0.02), Killip class >I (OR=7.14; p<0.01), anterior wall AMI (RR=2.37; p=0.02) and previous stroke (RR=2.34; p=0.04) were the main independent predictors of hospital death. Thrombolytic therapy was used in 143 patients (36.8%), aspirin in 322 (83%), beta blockers in 204 (52.6%) and heparin in 248 (63.9%). Cardiogenic shock was responsible for more than half of the death cases. Conclusion-Based on the data presented, older age, Killip class and anterior wall infarction are still important predictors of death due to AMI in the thrombolytic era, confirming other studies.
