Objective: To investigate the rate of colorectal neoplasms (CRNs) in patients who have Enterococcus faecalis infective endocarditis (EFIE) with available colonoscopies and to assess whether this is associated with the identification of a focus the infection. Patients and Methods: Retrospective analysis of data from a prospective multicenter study involving 35 centers who are members of the Grupo de Apoyo para el Manej o de la Endocarditis en Espana [Support Group for the Management of Infective Endocarditis in Spain] cohort. A specific set of queries regarding information on colonoscopy and histopathology of colorectal diseases was sent to each participating center. Four-hundred sixty-seven patients with EFIE were included from January 1, 2008, to December 31, 2017, from whom data on colonoscopy performance and results were available in 411 patients. Results: One hundred forty-two (34.5%) patients had a colonoscopy close to the EFIE episode. The overall rate of colorectal diseases was 70.4% (100 of 142), whereas the prevalence of CRN (advanced adenomas and colorectal carcinoma) was 14.8% (21 of 142), with no significant differences between the group of EFIE of unknown focus and that with an identified focus. Conclusion: Our study adds to prior evidence suggesting a much higher rate of CRN among patients with EFIE than in the general population of the same age and sex. In addition, our findings suggest that this phenomenon might take place both in EFIE with an unknown and an identified source of infection.

OBJECTIVES: Several risk prediction models have been developed to estimate the risk of mortality after valve surgery for active infective endocarditis (IE), but few external validations have been conducted to assess their accuracy. We previously developed a systematic review and meta-analysis of the impact of IE-specific factors for the in-hospital mortality rate after IE valve surgery, whose obtained pooled estimations were the basis for the development of a new score (APORTEI). The aim of the present study was to assess its prognostic accuracy in a nationwide cohort. METHODS: We analysed the prognostic utility of the APORTEI score using patient-level data from a multicentric national cohort. Patients who underwent surgery for active IE between 2008 and 2018 were included. Discrimination was evaluated using the area under the receiver operating characteristic curve, and the calibration was assessed using the calibration slope and the Hosmer-Lemeshow test. Agreement between the APORTEI and the EuroSCORE I was also analysed by Lin's concordance correlation coefficient (CCC), the Bland-Altman agreement analysis and a scatterplot graph. RESULTS: The 11 variables that comprised the APORTEI score were analysed in the sample. The APORTEI score was calculated in 1338 patients. The overall observed surgical mortality rate was 25.56%. The score demonstrated adequate discrimination (area under the receiver operating characteristic curve = 0.75; 95% confidence interval 0.72-0.77) and calibration (calibration slope = 1.03; Hosmer-Lemeshow test P = 0.389). We found a lack of agreement between the APORTEI and EuroSCORE I (concordance correlation coefficient = 0.55). CONCLUSIONS: The APORTEI score, developed from a systematic review and meta-analysis, showed an adequate estimation of the risk of mortality after IE valve surgery in a nationwide cohort.

Introduction: Our aims were to investigate the adherence to national guidelines of initial antiretroviral therapy (ART) in the Spanish multicenter CoRIS cohort during the years 2010-2015, to identify the reasons for the prescription of nonrecommended treatments, and to explore the role of institutional constraints to guideline compliance. Methods: ART regimens were classified as recommended, alternative or nonrecommended according to the guidelines. Physicians were asked the reasons for prescribing nonrecommended regimens. Factors associated with the prescription of non recommended regimens were assessed using multivariable logistic regression. Results: During the study period, 586 (10.7%) of 5479 patients who started ART were given a regimen not recommended in the guidelines. The most frequent reasons for prescribing nonrecommended regimens were: enrolment in clinical trials (43.3%), comorbidities and/or interactions (10.2%), pregnancy (8.7%), and cost (7.7%). Among 37 participating centers, 16 (43%), treating 3561 patients, reported limitations related with the cost of ART, and 20 (54%), treating 1365 patients, reported restrictions for prescribing at least one recommended antiretroviral. In multivariable analysis, a higher risk of receiving nonrecommended regimens was associated with male gender, HIV acquisition by heterosexual transmission, low viral loads, initiation of treatment during the years 2011 to 2015, and initiation of treatment in a center with restricted access to at least one antiretroviral drug. Conclusions: Compliance to clinical guidelines was high. A high proportion of centres reported cost limitations for ART or restricted access to at least one recommended antiretroviral drug, with a significant impact on the choice of initial regimens.

Objectives: To compare clinical and microbiological characteristics, treatment and outcomes of MRSA bacteraemia among elderly and younger patients. Material and methods: Prospective study conducted at 21 Spanish hospitals including patients with MRSA bacteraemia diagnosed between June/2008 and December/2009. Episodes diagnosed in patients aged 75 or more years old (>= 75) were compared with the rest of them (= 75. Comorbidity was significantly higher in older patients (Charlson score >= 4: 52.8 vs. 44%; p = .037) as was the severity of the underlying disease (McCabe >= 1: 61.9 vs. 43.4%; p < .001). In this group the acquisition was more frequently health-care related (43.3 vs. 33.9%, p = .023), mostly from long-term care centers (12.1 vs. 3.7%, p < .001). An unknown focus was more frequent among >= 75 (19.9 vs. 13.8%; p = .050) while severity at presentation was similar between groups (Pitt score >= 3: 31.2 vs. 27.6%; p = .352). The prevalence of vancomycin resistant isolates was similar between groups, as was the appropriateness of empirical antibiotic therapy. Early (EM) and overall mortality (OM) were significantly more frequent in the >= 75 group (EM: 12.1 vs. 6%; p = .010 OM: 42.9 vs. 23%; p < .001). In multivariate analysis age >= 75 was an independent risk factor for overall mortality (aOR: 2.47, CI: 1.63-3.74; p < .001). Conclusion: MRSA bacteraemia was frequent in patients aged >= 75 of our cohort. This group had higher comorbidity rates and the source of infection was more likely to be unknown. Although no differences were seen in severity or adequacy of empiric therapy, elderly patients showed a higher overall mortality. (C) 2015 The British Infection Association.

A high proportion of patients with methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia die within a few days of the onset of infection. However, predictive factors for early mortality (EM) have barely been examined. The aim of this study was to determine the predictive factors for EM in patients with MRSA bacteraemia. All episodes of MRSA bacteraemia were prospectively followed in 21 Spanish hospitals from June 2008 to December 2009. Epidemiology, clinical data, therapy and outcome were recorded. All MRSA strains were analysed in a central laboratory. Mortality was defined as death from any cause occurring in the 30 days after the onset of MRSA bacteraemia. EM was defined as patients who died within the first 2 days, and late mortality (LM) for patients who died after this period. Multivariate analyses were performed by using logistic regression models. A total of 579 episodes were recorded. Mortality was observed in 179 patients (31): it was early in 49 (8.5) patients and late in 130 (22.5). Independent risk factors for EM were [OR (95 CI)] initial Pitt score 3 [3.99 (1.723.24)], previous rapid fatal disease [3.67 (1.3210.24)], source of infection lower respiratory tract or unknown [3.76 (1.3110.83) and 2.83 (1.117.21)], non-nosocomial acquisition [2.59 (1.165.77)] and inappropriate initial antibiotic therapy [3.59 (1.637.89)]. When predictive factors for EM and LM were compared, inappropriate initial antibiotic therapy was the only distinctive predictor of EM, while endocarditis and lower respiratory tract sources both predicted LM. In our large cohort of patients several factors were related to EM, but the only distinctive predictor of EM was inappropriate initial antibiotic therapy.

Background: The aim of the study was to determine clinical and microbiological differences between patients with methicillin-resistant Staphylococcus aureus (MRSA) catheter-related bacteraemia (CRB) undergoing or not undergoing haemodialysis, and to compare outcomes. Methods: Prospective multicentre study conducted at 21 Spanish hospitals of patients with MRSA bacteraemia diagnosed between June 2008 and December 2009. Patients with MRSA-CRB were selected. Data of patients on haemodialysis (HD-CRB) and those not on haemodialysis (non-HD-CRB) were compared. Results: Among 579 episodes of MRSA bacteraemia, 218 (37.7 %) were CRB. Thirty-four (15.6 %) were HD-CRB and 184 (84.4 %) non-HD-CRB. All HD-CRB patients acquired the infection at dialysis centres, while in 85.3 % of the non-HD-CRB group the infection was nosocomial (p < .001). There were no differences in age, gender or severity of bacteraemia (Pitt score); comorbidities (Charlson score >= 4) were higher in the HD-CRB group than in the non-HD-CRB group (73.5 % vs. 46.2 %, p = .003). Although there were no differences in VAN-MIC >= 1.5 mg/L according to microdilution, using the E-test a higher rate of VAN-MIC >= 1.5 mg/L was observed in HD-CRB than in non-HD-CRB patients (63.3 % vs. 44.1 %, p = .051). Vancomycin was more frequently administered in the HD-CRB group than in the non-HD-CRB group (82.3 % vs. 42.4 %, p =, This study was supported by Ministerio de Ciencia e Innovacion, Instituto de Salud Carlos III (FIS 08/0335) and co-financed by the European Development Regional Fund 'A way to achieve Europe' ERDF, Spanish Network for Research in Infectious Diseases (REIPI RD06/0008).; O.
