The aim of this study was to analyze the donor risk factors associated with second orthotopic liver transplantation (reOLT) and graft loss after OLT within 1 month. A total of 649 OLTs performed in 11 centers in Spain during the period from 1992 to 1993 were analyzed retrospectively. Eleven donor and recipient variables were studied. Biochemical evolution of the OLT, biliary and arterial complications, patient status (alive, retransplanted, or dead), and follow-up were also recorded. Bivariate study demonstrated that extended preservation ( > 12 hr) was associated with increased biliary complications (P = 0.02), and lower prothrombin time (P = 0.04). In a logistic model regression for biliary complications, ischemia > 12 hr was an independent risk factor (odds ratio = 2.2, 95% confidence interval [CI] = 1.1-4.3). The multivariate Cox proportional model of potential risk factors showed that only urgent reOLT (relative risk [RR] = 2.7, 95% CI = 1.4-5.4) was independently associated with higher 30-day mortality. Donor plasma sodium > 155 mmol/L (RR = 1.4, 95% CI = 1.0-2.2) and incompatible ABO graft (RR = 3.2, 95% CI = 1.3-7.9) were independently associated with increased rate of reOLT before 30 days. Donor plasma sodium > 155 mmol/L (RR = 2, 95% CI = 1.1-3.6) and incompatible graft (RR = 3.3, 95% CI = 1.4-8.2) were independently associated with graft loss (death or reOLT) before 1 month. We conclude that cold ischemia should be kept less than 12 hr in order to avoid biliary complications. Donors over 60 years old or with plasma sodium > 155 should be carefully evaluated before OLT.
This study was designed to determine the prevalence of healthy Haemophilus influenzae carriers in a random sample of the preschool population in Catalonia. Oropharyngeal swabs were collected and cultured on chocolate agar supplemented with 260 microg/ml of bacitracin. Four hundred two of the 734 (54.8%) children studied were detected as Haemophilus influenzae carriers: 7 (0.9%) carried serotype b, 14 (1.9%) serotype e, 6 (0.8%) serotype f, and 375 (51%) carried nontypable strains. The results show that, although the prevalence of Haemophilus influenzae carriers is similar to figures reported from other countries, the prevalence of Haemophillus influenzae serotype b carriers is lower and corresponds with the low incidence of invasive disease observed in the Catalan community.
Animal fat intake was associated with prostate cancer with an estimated OR for highest quartile of 2.0 (95% CI 1.2-3.2). Vitamin C intake was inversely associated with prostate cancer (OR = 0.6; 95% CI 0.3-0.9). The prostate cancer risk increased in proportion to alpha-linolenic acid intake. In the analysis adjusting for energy and major covariables the estimated OR for upper quartile of alpha-linolenic acid was 3.1 (95% CI 1.1-3.8). In conclusion, the association between fat intake and prostate cancer may be correlated with alpha-linolenic acid, although the specific mechanism has to be determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
