    The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

    Impression and compression of vascular structures by a giant left atriumSe presentan imĂĄgenes tomogrĂĄficas de una paciente de 28 años de edad, operada por insuficiencia mitral, con una aurĂ­cula izquierda gigante (82 ÂŽ 54 mm; volumen 465 ml) que produce la impresiĂłn de un surco vertical en la porciĂłn media de la pared posterior de la aurĂ­cula izquierda. Los artĂ­culos que han abordado este tema en los Ășltimos años asumen que la impresiĂłn debe ser provocada por una estructura patolĂłgica (aumentada de volumen) dorsal a la aurĂ­cula. Sin embargo, en nuestro caso, semejante a lo informado en los primeros trabajos relacionados con este tema, la impresiĂłn se ha originado por una aurĂ­cula izquierda dilatada, que se ha proyectado posteriormente para “abrazar” la aorta torĂĄcica descendente normal. La aorta ascendente estampa igualmente un surco en la pared anterior del atrio izquierdo, la que –a su vez– comprime (de forma asintomĂĄtica) el segmento proximal del tronco de la coronaria izquierda, lo que ocasiona una angulaciĂłn recta (cerca de 90°) y un cambio de direcciĂłn brusco del resto de la arteria

    Resumen: Objetivo: Determinar los beneficios transoperatorios de la colocación de un separador retråctil de pulmón durante la disección esqueletizada de la arteria mamaria, en la cirugía de revascularización miocårdica. Métodos: Estudio transversal descriptivo. Se analizaron variables transoperatorias de 62 pacientes que necesitaron colocación del separador de pulmón durante la disección de la arteria mamaria izquierda. Resultados: La disponibilidad del separador permitió su uso en 57 pacientes. La duración de la disección mamaria fue significativamente mås prolongada cuando no se empleó el separador (55,5 ± 4,5 vs. 50,4 ± 4,67 min). También hubo mås sangrado durante el procedimiento en ese grupo (69 ± 20,74 vs. 57,2 ± 12,17 ml). Se conservó la integridad de la cavidad pleural en el 87,7% de los pacientes en que se empleó el separador. Conclusiones: Se demostraron beneficios evidentes con el uso del separador de pulmón en cuanto a disminución del tiempo de disección mamaria y conservación de la integridad de la cavidad pleural y de la vena mamaria. Abstract: Objective: To determine the trans-operative benefits of a malleable lung retractor placement during skeletonised internal mammary artery harvesting in coronary artery bypass graft surgery. Methods: A descriptive cross-sectional study was conducted by analysing the trans-operative variables of 62 patients who required a lung retractor placement during left internal mammary artery harvesting. Results: The separator was used in 57 patients. The duration of mammary dissection was significantly longer when the retractor was not used (55.5 ± 4.5 vs. 50.4 ± 4.67 min). There was also more bleeding during the procedure in that group (69 ± 20.74 vs. 57.2 ± 12.17 ml). Pleural cavity integrity was preserved in 87.7% of the patients in whom the retractor was used. Conclusions: Clear benefits of the use of lung retractor were demonstrated in terms of decreased mammary artery dissection time, and preservation of pleural cavity, as well as mammary vein integrity.

    Internal thoracic artery dissection is one of the most defining procedures of coronary artery bypass grafting, as it has been demonstrated that the quality of life and short-long term outcome of patients will depend on the morphological characteristics of the graft. More than 25 years ago, the use of a malleable lung spreader was proposed to facilitate the internal thoracic artery dissection especially its proximal segment, but that device has never been manufactured. A lung spreader, assembled from disused devices, used in coronary artery revascularization is presented. The main advantages confirmed over more than three years in nearly a hundred patients are discussed and commented upon.La disección de la arteria toråcica interna es uno de los procedimientos mås definitorios de la cirugía de revascularización miocårdica, pues se ha demostrado que la calidad de vida y la evolución a corto y largo plazo de los pacientes dependerån de las características morfológicas del injerto. Hace mås de 25 años se propuso la utilización de un separador pulmonar maleable para facilitar la disección de la arteria toråcica interna, especialmente su segmento proximal, pero nunca se ha fabricado ese dispositivo. Se presenta un separador pulmonar manufacturado a partir de dispositivos en desuso, empleados en cirugía coronaria. Se comentan y discuten las principales ventajas demostradas durante mås de tres años en cerca de un centenar de pacientes

    Introduction: Infective endocarditis has not decreased its incidence and mortality in the last 30 years. Objective: To characterize patients operated on due to diagnosis of active infec-tive endocarditis. Methods: A retrospective, descriptive study was carried out, which included 109 patients with a diagnosis of this disease, who underwent surgery at Cardiocentro Ernesto Che Guevara (Cuba), from July 2010 to June 2018. The information was obtained from the medical records and the surgical report. Results: Prosthetic valve infective endocarditis was diagnosed in 15 patients (13.8%), but the most frequent was the one related to intracardiac device coloniza-tion (51.4%), reason why the most used surgical procedure was the change of the electrical stimulation system. The main surgical indication was the uncontrolled infection in 63 cases (57.8%), followed by heart failure (38 patients; 34.9%) and in 67 cases (61.5%), the blood cultures were negative. The native valve replacement for a mechanical prosthetic valve was performed in 28 patients (25.7%), of which 15 (13.8%) were in mitral position. The replacement of a mechanical prosthetic valve for another with the same characteristics was carried out in 14 (12.8%) cases, 8 (7.3%) of them were mitral. Overall mortality was of 17.4%, more evident in those with left-side prosthetic valve endocarditis (7/15). Conclusions: Male gender and age over 60 years old predominated, as well as the presence of vegetations on intracardiac devices, and negative blood cultures. The prosthetic valve endocarditis was significantly associated with mortality.IntroducciĂłn: La endocarditis infecciosa no ha disminuido su incidencia y mortalidad en los Ășltimos 30 años. Objetivo: Caracterizar los pacientes operados por diagnĂłstico de endocarditis infecciosa activa. MĂ©todo: Se realizĂł un estudio descriptivo retrospectivo que incluyĂł a 109 pacien- tes con diagnĂłstico de esta enfermedad y fueron intervenidos quirĂșrgicamente en el Cardiocentro Ernesto Che Guevara (Cuba) desde julio de 2010 hasta junio de 2018. La informaciĂłn se obtuvo de las historias clĂ­nicas y el informe operatorio. Resultados: La endocarditis infecciosa sobre vĂĄlvula protĂ©sica fue diagnosticada en 15 pacientes (13,8%), pero la mĂĄs frecuente fue la relacionada con la coloniza-ciĂłn de dispositivos intracardĂ­acos (51,4%), razĂłn por la que el procedimiento quirĂșrgico mĂĄs utilizado fue el cambio de sistema de estimulaciĂłn. La principal indicaciĂłn quirĂșrgica fue la infecciĂłn incontrolada en 63 casos (57,8%), seguida por la insuficiencia cardĂ­aca (38 pacientes; 34,9%) y en 67 casos (61,5%) los hemo-cultivos resultaron negativos. La sustituciĂłn de la vĂĄlvula nativa por una prĂłtesis mecĂĄnica se realizĂł en 28 pacientes (25,7%), de los cuĂĄles 15 (13,8%) fueron en posiciĂłn mitral. El recambio de una prĂłtesis mecĂĄnica por otra de igual caracterĂ­s-ticas se llevĂł a cabo en 14 (12,8%) casos, 8 (7,3%) de ellos mitrales. La mortalidad global fue de 17,4%, mĂĄs evidente en aquellos con endocarditis sobre vĂĄlvula pro-tĂ©sica izquierda (7/15). Conclusiones: Predominaron el sexo masculino y la edad mayor de 60 años, asĂ­ como la presencia de vegetaciones sobre dispositivos intracardĂ­acos y los hemo-cultivos negativos. La endocarditis sobre vĂĄlvula protĂ©sica se asociĂł significativamente con la mortalidad

    The association of two tumors of different origin in the same patient is becoming more frequent in the current clinical practice. Here is presented a case with a rare association of cardiac myxoma and hypernephroma, previously treated. Due to the presence of neurological symptoms, there was initially set a diagnosis of brain metastasis from the renal tumor; then, with the echocardiographic finding of an intracardiac mass, the possibility of thrombus was considered, therefore a cardiac surgery was decided to be performed urgently in order to resect it. The pathologic examination confirmed the existence of a cardiac myxoma, then, we have a patient with two tumor diseases whose coincidence has been rarely described.La asociaciĂłn de dos tumores de diferente origen en un mismo paciente es cada vez mĂĄs frecuente en la prĂĄctica clĂ­nica actual. Se presenta un caso con una rara asociaciĂłn de mixoma cardĂ­aco e hipernefroma, previamente tratado. Ante la presencia de manifestaciones neurolĂłgicas, inicialmente se planteĂł el diagnĂłstico de metĂĄstasis cerebral del tumor renal; luego, con el hallazgo ecocardiogrĂĄfico de una masa intracardĂ­aca, se pensĂł en la posibilidad de trombo, por lo que se decidiĂł practicar cirugĂ­a cardĂ­aca con carĂĄcter urgente para resecarla. El estudio anatomopatolĂłgico confirmĂł la existencia de un mixoma cardĂ­aco, por lo que se trata de un enfermo con dos enfermedades tumorales cuya coincidencia ha sido pocas veces descrita

    Background: Inborn errors of immunity (IEI) are rare diseases, which makes diagnosis a challenge. A better description of the initial presenting manifestations should improve awareness and avoid diagnostic delay. Although increased infection susceptibility is a well-known initial IEI manifestation, less is known about the frequency of other presenting manifestations. Objective: We sought to analyze age-related initial presenting manifestations of IEI including different IEI disease cohorts. Methods: We analyzed data on 16,486 patients of the European Society for Immunodeficiencies Registry. Patients with autoinflammatory diseases were excluded because of the limited number registered. Results: Overall, 68% of patients initially presented with infections only, 9% with immune dysregulation only, and 9% with a combination of both. Syndromic features were the presenting feature in 12%, 4% had laboratory abnormalities only, 1.5% were diagnosed because of family history only, and 0.8% presented with malignancy. Two-third of patients with IEI presented before the age of 6 years, but a quarter of patients developed initial symptoms only as adults. Immune dysregulation was most frequently recognized as an initial IEI manifestation between age 6 and 25 years, with male predominance until age 10 years, shifting to female predominance after age 40 years. Infections were most prevalent as a first manifestation in patients presenting after age 30 years. Conclusions: An exclusive focus on infection-centered warning signs would have missed around 25% of patients with IEI who initially present with other manifestations.

    The risk of COVID-19 death is much greater and age dependent with type I IFN autoantibodies

    International audienceSignificance There is growing evidence that preexisting autoantibodies neutralizing type I interferons (IFNs) are strong determinants of life-threatening COVID-19 pneumonia. It is important to estimate their quantitative impact on COVID-19 mortality upon SARS-CoV-2 infection, by age and sex, as both the prevalence of these autoantibodies and the risk of COVID-19 death increase with age and are higher in men. Using an unvaccinated sample of 1,261 deceased patients and 34,159 individuals from the general population, we found that autoantibodies against type I IFNs strongly increased the SARS-CoV-2 infection fatality rate at all ages, in both men and women. Autoantibodies against type I IFNs are strong and common predictors of life-threatening COVID-19. Testing for these autoantibodies should be considered in the general population
