Long-term antibiotic therapy in patients with surgery-indicated not undergoing surgery infective endocarditis.

BACKGROUND: To date, there is little information regarding management of patients with infective endocarditis (IE) that did not undergo an indicated surgery. Therefore, we aimed to evaluate prognosis of these patients treated with a long-term antibiotic treatment strategy, including oral long term suppressive antibiotic treatment in five referral centres with a multidisciplinary endocarditis team. METHODS: This retrospective, multicenter study retrieved individual patient-level data from five referral centres in Spain. Among a total of 1797, 32 consecutive patients with IE were examined (median age 72 years; 78% males) who had not undergone an indicated surgery, but received long-term antibiotic treatment (LTAT) and were followed by a multidisciplinary endocarditis team, between 2011 and 2019. Primary outcomes were infection relapse and mortality during follow-up. RESULTS: Among 32 patients, 21 had IE associated with prostheses. Of the latter, 8 had an ascending aorta prosthetic graft. In 24 patients, a switch to long-term oral suppressive antibiotic treatment (LOSAT) was considered. The median duration of LOSAT was 277 days. Four patients experienced a relapse during follow-up. One patient died within 60 days, and 12 patients died between 60 days and 3 years. However, only 4 deaths were related to IE. CONCLUSIONS: The present study results suggest that a LTAT strategy, including LOSAT, might be considered for patients with IE that cannot undergo an indicated surgery. After hospitalization, they should be followed by a multidisciplinary endocarditis team.

Defining persistent Staphylococcus aureus bacteraemia: secondary analysis of a prospective cohort study.

BACKGROUND: Staphylococcus aureus persistent bacteraemia is only vaguely defined and the effect of different durations of bacteraemia on mortality is not well established. Our primary aim was to analyse mortality according to duration of bacteraemia and to derive a clinically relevant definition for persistent bacteraemia. METHODS: We did a secondary analysis of a prospective observational cohort study at 17 European centres (nine in the UK, six in Spain, and two in Germany), with recruitment between Jan 1, 2013, and April 30, 2015. Adult patients who were consecutively hospitalised with monomicrobial S aureus bacteraemia were included. Patients were excluded if no follow-up blood culture was taken, if the first follow-up blood-culture was after 7 days, or if active antibiotic therapy was started more than 3 days after first blood culture. The primary outcome was 90-day mortality. Univariable and time-dependent multivariable Cox regression analysis were used to assess predictors of mortality. Duration of bacteraemia was defined as bacteraemic days under active antibiotic therapy counting the first day as day 1. FINDINGS: Of 1588 individuals assessed for eligibility, 987 were included (median age 65 years [IQR 51-75]; 625 [63%] male). Death within 90 days occurred in 273 (28%) patients. Patients with more than 1 day of bacteraemia (315 [32%]) had higher Charlson comorbidity index and sequential organ failure assessment scores and a longer interval from first symptom to first blood culture. Crude 90-day mortality increased from 22% (148 of 672) with 1 day of bacteraemia, to 39% (85 of 218) with 2-4 days, 43% (30 of 69) with 5-7 days, and 36% (10 of 28) with more than 7 days of bacteraemia. Metastatic infections developed in 39 (6%) of 672 patients with 1 day of bacteraemia versus 40 (13%) of 315 patients if bacteraemia lasted for at least 2 days. The second day of bacteraemia had the highest HR and earliest cutoff significantly associated with mortality (adjusted hazard ratio 1·93, 95% CI 1·51-2·46; p<0·0001). INTERPRETATION: We suggest redefining the cutoff duration for persistent bacteraemia as 2 days or more despite active antibiotic therapy. Our results favour follow-up blood cultures after 24 h for early identification of all patients with increased risk of death and metastatic infection. FUNDING: None.

Reflexiones sobre los Tribunales de las Oposiciones Universitarias / Thoughs on Competitive Examination for University Professors

La medicina presenta cambios clínicos, terapéuticos, y tecnológicos, coincidiendo con variaciones demográficas culturales y epidemiológicas. Este conjunto de factores y la rapidez con la que se suceden las innovaciones en todos los campos, obliga a replantearse la formación de los médicos, no sólo durante su periodo inicial universitario, sino también a lo largo de toda su vida profesional. Los tribunales de selección de los profesionales que llevarán el peso de la formación universitaria, deben de atender a todas estas dimensiones para asegurar que los futuros profesores transmitan estos valores a los estudiantes. A su vez, los candidatos deben de conocer aquellos puntos sobre los que construir su currículum (AU)

Medicine is undergoing clinical, therapeutic and technological changes, and this is coinciding with demographic, cultural and epidemiological variations. These factors, and the speed with which innovations occur in all fields, requires a rethink of doctors' training, not only during their initial university studies but also throughout their professional life. Those responsible for appointing medical school lecturers must take into account all these aspects in order to ensure that the teaching staff of the future will transmit these values to students. In turn, candidates must be aware of the key aspects around which they should develop their curriculu (AU)
