Bouguer anomalies of the NW Iberian continental margin and the adjacent abyssal plains
The NW Iberian continental margin has a complex structure, resulting from the succession of several rifting episodes close to a ridge triple junction, and a superimposed partial tectonic inversion stage. The wide-ranging physiography matches the diverse tectonic deformation domains related to its evolution. Each deformation domain has a distinctive gravity signal, so the detailed Bouguer anomaly map presented here is a good first approach to the regional study of the whole margin. Moreover, as the presented chart is a complete Bouguer anomaly map (including terrain corrections), its analysis and interpretation can be done in terms of density, geometry and depth variations below the seafloor. This map is mainly based on the dataset obtained during seven one-month surveys carried out in the frame of the Spanish Economic Exclusive Zone project, and also includes two 2 + 3/4D density models illustrating the deep structure of the marginThe marine surveys are supported by the Spanish Defense Ministry, as this is the managing body of the Spanish Exclusive Economic Zone Project (SEEZ). Additionally, the Universidad Complutense de Madrid funds travel expenses of its personnel embarking on the surveys, as does the Instituto Geológico y Minero de España in the frame of the internal project entitled ‘Plan de Investigaciones Geológicas y Geofísicas de la Zona Económica Exclusiva Española (ZEEE)
Análisis Retrospectivo de los casos de Endocarditis Infecciosa a lo largo de 31 años (1985-2016) en un Hospital Terciario (Ramón y Cajal)
La Endocarditis Infecciosa (EI) es una enfermedad infrecuente, de alta mortalidad. En las últimas décadas ha habido cambios relevantes tanto en las técnicas de diagnóstico por imagen como en la epidemiología de la población a la que afecta, que son el objeto de nuestro trabajo. Como método de trabajo se ha realizado un estudio observacional retrospectivo. Se han revisado las historias clínicas de los pacientes diagnosticados de Endocarditis Infecciosa en el Hospital Ramón y Cajal en los últimos 31 años (1985-2016), a partir de un registro del Servicio de Enfermedades Infecciosas. Se ha obtenido como resultado, que el número de casos de Endocarditis Infecciosa se ha mantenido estable a lo largo de los 31 años del estudio. La mayor frecuencia en varones (67%) se mantuvo constante, mientras que la edad de los pacientes ha ido aumentando progresivamente. Se ha apreciado cambios en los microorganismos causales, entre los cuales los más frecuentemente aislados han sido Staphylococcus aureus (37,3%), seguido de estafilococos coagulasa-negativo (14,3%) y Streptococcus viridans (13,2%). De modo llamativo, disminuyeron significativamente los casos de EI asociada al uso de drogas inyectadas y aumentaron proporcionalmente los de EI sobre válvula natural (39,5%) y sobre válvula protésica (31.5%). También aumentaron el empleo del ecocardiograma transesofágico en el diagnóstico (43,7%) y los casos que se sometieron a cirugía (28,9%). La cifra de endocarditis nosocomial sigue siendo un problema importante (12,4%). La mortalidad se ha mantenido elevada sin cambios (20%). Como conclusión podemos señalar que se han encontrado cambios significativos en la epidemiología de la enfermedad a lo largo de los 31 años del estudio, en parte asociado a la disminución del uso de drogas inyectadas y al aumento de los procedimientos quirúrgicos sobre el corazón. Pese a los avances en el manejo diagnóstico y terapéutico la enfermedad sigue teniendo una mortalidad elevada.Infective endocarditis is an uncommon disease of high mortality. In recent decades there have been significant changes both in image diagnostic techniques and in the epidemiology of the affected population, which are the subject of our work. Observational retrospective study. We have reviewed the medical records of patients diagnosed with infective endocarditis in the Hospital Ramon y Cajal in the past 31 years (1985-2016), included in a registry of the Service of Infectious Diseases. The number of cases of infective endocarditis has remained stable over the 31 years of the study. A higher frequency in males (67%) has remained constant, while the age of patients has progressively increased. Changes have been observed in the causative organisms, among which Staphylococcus aureus was the most frequently isolated (37.3%), followed by coagulase-negative staphylococci (14.3%) and Streptococcus viridans (13.2%). Strikingly, there was a significant reduction in the number of cases of endocarditis associated with injection drug use and an increase in those on natural valve (39.5%) and prosthetic valve (31.5%). We also found an increase in the use of transesophageal ecocardiogram in the diagnosis (43.7%) and cases who underwent surgery (28.9%). The number of nosocomial endocarditis continues to be a major problem (12.4%). Mortality has remained high without changes (20%). We have found significant changes in the epidemiology of the disease over the 31 years of the study, in part associated to the decrease in the use of injected drugs and the increase of the surgical procedures on the heart. Diagnostic and therapeutic handling also has advanced, but despite this disease continues to have a high mortality

Consorcio de Investigación Biomédica en Red de Enfermedades Hepáticas y Digestivas is financed by the ISCIII.Background: It is necessary to develop a safe alternative to isoniazid for tuberculosis prophylaxis in liver transplant recipients. This study was designed to investigate the efficacy and safety of levofloxacin.
Methods: An open-label, prospective, multicenter, randomized study was conducted to compare the efficacy and safety of levofloxacin (500 mg q24h for 9 months) initiated in patients awaiting liver transplantation and isoniazid (300 mg q24h for 9 months) initiated post-transplant when liver function was stabilized. Efficacy was measured by tuberculosis incidence at 18 months after transplantation. All adverse events related to the medication were recorded.
Results: CONSORT guidelines were followed in order to present the results. The safety committee suspended the study through a safety analysis when 64 patients had been included (31 in the isoniazid arm and 33 in the levofloxacin arm). The reason for suspension was an unexpected incidence of severe tenosynovitis in the levofloxacin arm (18.2%). Although the clinical course was favorable in all cases, tenosynovitis persisted for 7 weeks in some patients. No patients treated with isoniazid, developed tenosynovitis. Only 32.2% of patients randomized to isoniazid (10/31) and 54.5% of patients randomized to levofloxacin (18/33, P = .094) completed prophylaxis. No patient developed tuberculosis during the study follow-up (median 270 days).
Conclusions: Levofloxacin prophylaxis of tuberculosis in liver transplant candidates is associated with a high incidence of tenosynovitis that limits its potential utility.Ayudas para el fomento de la investigación clínica independiente [EC 10-120]Programa Intramural Consorcio de Apoyo a la Investigación Biomédica en Red 2010National R&D&I Plan 2008–2011Instituto de Salud Carlos III (ISCIII)Ministerio de Economía y Competitividad RD06/0008, RD12/0015European Development Regional Fun
Pseudomonas aeruginosa bloodstream infections in patients with cancer: differences between patients with hematological malignancies and solid tumors
Objectives: To assess the clinical features and outcomes of Pseudomonas aeruginosa bloodstream infection (PA BSI) in neutropenic patients with hematological malignancies (HM) and with solid tumors (ST), and identify the risk factors for 30-day mortality.
Methods: We performed a large multicenter, retrospective cohort study including onco-hematological neutropenic patients with PA BSI conducted across 34 centers in 12 countries (January 2006-May 2018). Episodes occurring in hematologic patients were compared to those developing in patients with ST. Risk factors associated with 30-day mortality were investigated in both groups.
Results: Of 1217 episodes of PA BSI, 917 occurred in patients with HM and 300 in patients with ST. Hematological patients had more commonly profound neutropenia (0.1 × 109 cells/mm) (67% vs. 44.6%; p < 0.001), and a high risk Multinational Association for Supportive Care in Cancer (MASCC) index score (32.2% vs. 26.7%; p = 0.05). Catheter-infection (10.7% vs. 4.7%; p = 0.001), mucositis (2.4% vs. 0.7%; p = 0.042), and perianal infection (3.6% vs. 0.3%; p = 0.001) predominated as BSI sources in the hematological patients, whereas pneumonia (22.9% vs. 33.7%; p < 0.001) and other abdominal sites (2.8% vs. 6.3%; p = 0.006) were more common in patients with ST. Hematological patients had more frequent BSI due to multidrug-resistant P. aeruginosa (MDRPA) (23.2% vs. 7.7%; p < 0.001), and were more likely to receive inadequate initial antibiotic therapy (IEAT) (20.1% vs. 12%; p < 0.001). Patients with ST presented more frequently with septic shock (45.8% vs. 30%; p < 0.001), and presented worse outcomes, with increased 7-day (38% vs. 24.2%; p < 0.001) and 30-day (49% vs. 37.3%; p < 0.001) case-fatality rates. Risk factors for 30-day mortality in hematologic patients were high risk MASCC index score, IEAT, pneumonia, infection due to MDRPA, and septic shock. Risk factors for 30-day mortality in patients with ST were high risk MASCC index score, IEAT, persistent BSI, and septic shock. Therapy with granulocyte colony-stimulating factor was associated with survival in both groups.
Conclusions: The clinical features and outcomes of PA BSI in neutropenic cancer patients showed some differences depending on the underlying malignancy. Considering these differences and the risk factors for mortality may be useful to optimize their therapeutic management. Among the risk factors associated with overall mortality, IEAT and the administration of granulocyte colony-stimulating factor were the only modifiable variables.Funding: This study was supported by the Instituto de Salud Carlos III, Subdirección General de Redes y Centros de Investigación Cooperativa, Ministerio de Economía, Industria y Competitividad, Centro de Investigación Biomédica en Red de Enfermedades Infecciosas (CIBERINFEC) (CB21/13/00009; CB21/13/00079; CB21/13/00054; CB21/13/00086), Madrid, Spain.

Adherence to the Western, Prudent and Mediterranean dietary patterns and breast cancer risk: MCC-Spain study
Objective
To externally validate the previously identified effect on breast cancer risk of the Western, Prudent and Mediterranean dietary patterns.
Study design
MCC-Spain is a multicase-control study that collected epidemiological information on 1181 incident cases of female breast cancer and 1682 control cases from 10 Spanish provinces. Three dietary patterns derived in another Spanish case-control study were analysed in the MCC-Spain study. These patterns were termed Western (high intakes of fatty and sugary products and red and processed meat), Prudent (high intakes of low-fat dairy products, vegetables, fruits, whole grains and juices) and Mediterranean (high intake of fish, vegetables, legumes, boiled potatoes, fruits, olives, and vegetable oil, and a low intake of juices). Their association with breast cancer was assessed using logistic regression models with random province-specific intercepts considering an interaction with menopausal status. Risk according to tumour subtypes ? based on oestrogen (ER), progesterone (PR) and human epidermal growth factor 2 (HER2) receptors (ER+/PR+&HER2-; HER2+; ER-/PR-&HER2-) ? was evaluated with multinomial regression models.
Main outcome measures
Breast cancer and histological subtype.
Results
Our results confirm most of the associations found in the previous case-control study. A high adherence to the Western dietary pattern seems to increase breast cancer risk in both premenopausal women (OR4thvs.1stquartile(95%CI):1.68(1.02;2.79); OR1SD-increase(95%CI): 1.19(1.01;1.40)) and postmenopausal women (OR4thvs.1stquartile(95%CI):1.48(1.07;2.05); OR1SD-increase(95%CI): 1.14(1.01;1.28)). While high adherence to the Prudent pattern did not show any effect on breast cancer, the Mediterranean dietary pattern seemed to be protective, but only among postmenopausal women (OR4thvs.1stquartile (95%CI):0.72(95% CI 0.53;0.98); p-int = 0.075). There were no significant differences by tumour subtype.
Conclusion
Dietary recommendations based on a departure from the Western dietary pattern in favour of the Mediterranean diet could reduce breast cancer risk in the general population.The study was funded by Carlos III Institute of Health grants (PI12/00488, PI12/00265,

The aim was to analyze the characteristics and predictors of unfavorable outcomes in solid organ transplant recipients (SOTRs) with COVID-19. We conducted a prospective observational cohort study of 210 consecutive SOTRs hospitalized with COVID-19 in 12 Spanish centers from 21 February to 6 May 2020. Data pertaining to demographics, chronic underlying diseases, transplantation features, clinical, therapeutics, and complications were collected. The primary endpoint was a composite of intensive care unit (ICU) admission and/or death. Logistic regression analyses were performed to identify the factors associated with these unfavorable outcomes. Males accounted for 148 (70.5%) patients, the median age was 63 years, and 189 (90.0%) patients had pneumonia. Common symptoms were fever, cough, gastrointestinal disturbances, and dyspnea. The most used antiviral or host-targeted therapies included hydroxychloroquine 193/200 (96.5%), lopinavir/ritonavir 91/200 (45.5%), and tocilizumab 49/200 (24.5%). Thirty-seven (17.6%) patients required ICU admission, 12 (5.7%) suffered graft dysfunction, and 45 (21.4%) died. A shorter interval between transplantation and COVID-19 diagnosis had a negative impact on clinical prognosis. Four baseline features were identified as independent predictors of intensive care need or death: advanced age, high respiratory rate, lymphopenia, and elevated level of lactate dehydrogenase. In summary, this study presents comprehensive information on characteristics and complications of COVID-19 in hospitalized SOTRs and provides indicators available upon hospital admission for the identification of SOTRs at risk of critical disease or death, underlining the need for stringent preventative measures in the early post-transplant periodThis study was supported by Plan Nacional de I+D+i 2013-2016 and Instituto de Salud Carlos III, Subdirección General de Redes y Centros de Investigación Cooperativa, Ministerio de Ciencia, Innovación y Universidades, Spanish Network for Research in Infectious Diseases (REIPI RD16/0016); co-financed by European Development Regional Fund “A way to achieve Europe”, Operative Program Intelligence Growth 2014-2020.

Co-infections and superinfections complicating COVID-19 in cancer patients: A multicentre, international study
Background: We aimed to describe the epidemiology, risk factors, and clinical outcomes of co-infections and superinfections in onco-hematological patients with COVID-19. Methods: International, multicentre cohort study of cancer patients with COVID-19. All patients were included in the analysis of co-infections at diagnosis, while only patients admitted at least 48 h were included in the analysis of superinfections. Results: 684 patients were included (384 with solid tumors and 300 with hematological malignancies). Co-infections and superinfections were documented in 7.8% (54/684) and 19.1% (113/590) of patients, respectively. Lower respiratory tract infections were the most frequent infectious complications, most often caused by Streptococcus pneumoniae and Pseudomonas aeruginosa. Only seven patients developed opportunistic infections. Compared to patients without infectious complications, those with infections had worse outcomes, with high rates of acute respiratory distress syndrome, intensive care unit (ICU) admission, and case-fatality rates. Neutropenia, ICU admission and high levels of C-reactive protein (CRP) were independent risk factors for infections. Conclusions: Infectious complications in cancer patients with COVID-19 were lower than expected, affecting mainly neutropenic patients with high levels of CRP and/or ICU admission. The rate of opportunistic infections was unexpectedly low. The use of empiric antimicrobials in cancer patients with COVID-19 needs to be optimized
Clinical efficacy of β-lactam/β-lactamase inhibitor combinations for the treatment of bloodstream infection due to extended-spectrum β-lactamase-producing Enterobacteriaceae in haematological patients with neutropaenia: a study protocol for a retrospective observational study (BICAR)
Introduction: Bloodstream infection (BSI) due to extended-spectrum β-lactamase-producing Gram-negative bacilli (ESBL-GNB) is increasing at an alarming pace worldwide. Although β-lactam/β-lactamase inhibitor (BLBLI) combinations have been suggested as an alternative to carbapenems for the treatment of BSI due to these resistant organisms in the general population, their usefulness for the treatment of BSI due to ESBL-GNB in haematological patients with neutropaenia is yet to be elucidated. The aim of the BICAR study is to compare the efficacy of BLBLI combinations with that of carbapenems for the treatment of BSI due to an ESBL-GNB in this population. Methods and analysis: A multinational, multicentre, observational retrospective study. Episodes of BSI due to ESBL-GNB occurring in haematological patients and haematopoietic stem cell transplant recipients with neutropaenia from 1 January 2006 to 31 March 2015 will be analysed. The primary end point will be case-fatality rate within 30 days of onset of BSI. The secondary end points will be 7-day and 14-day case-fatality rates, microbiological failure, colonisation/infection by resistant bacteria, superinfection, intensive care unit admission and development of adverse events. Sample size: The number of expected episodes of BSI due to ESBL-GNB in the participant centres will be 260 with a ratio of control to experimental participants of 2. Ethics and dissemination: The protocol of the study was approved at the first site by the Research Ethics Committee (REC) of Hospital Universitari de Bellvitge. Approval will be also sought from all relevant RECs. Any formal presentation or publication of data from this study will be considered as a joint publication by the participating investigators and will follow the recommendations of the International Committee of Medical Journal Editors (ICMJE). The study has been endorsed by the European Study Group for Bloodstream Infection and Sepsis (ESGBIS) and the European Study Group for Infections in Compromised Hosts (ESGICH)
