The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

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.

Impresión y compresión de estructuras vasculares por una aurícula izquierda gigante

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

Beneficios inmediatos de la utilización de un separador pulmonar flexible durante la disección esqueletizada de la arteria mamaria interna

Resumen: Objetivo: Determinar los beneficios transoperatorios de la colocación de un separador retráctil de pulmón durante la disección esqueletizada de la arteria mamaria, en la cirugía de revascularización miocárdica. 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 más prolongada cuando no se empleó el separador (55,5 ± 4,5 vs. 50,4 ± 4,67 min). También hubo más 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.

Primer separador retráctil de pulmón para facilitar la disección extrapleural de la arteria torácica interna

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 torácica interna es uno de los procedimientos más definitorios de la cirugía de revascularización miocárdica, pues se ha demostrado que la calidad de vida y la evolución a corto y largo plazo de los pacientes dependerán de las características morfológicas del injerto. Hace más de 25 años se propuso la utilización de un separador pulmonar maleable para facilitar la disección de la arteria torácica 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 más de tres años en cerca de un centenar de pacientes

Caracterización clínico-epidemiológica con enfoque quirúrgico de la endocarditis infecciosa en la región central de Cuba

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.Introducción: La endocarditis infecciosa no ha disminuido su incidencia y mortalidad en los últimos 30 años. Objetivo: Caracterizar los pacientes operados por diagnóstico de endocarditis infecciosa activa. Método: Se realizó un estudio descriptivo retrospectivo que incluyó a 109 pacien- tes con diagnóstico de esta enfermedad y fueron intervenidos quirúrgicamente en el Cardiocentro Ernesto Che Guevara (Cuba) desde julio de 2010 hasta junio de 2018. La información se obtuvo de las historias clínicas y el informe operatorio. Resultados: La endocarditis infecciosa sobre válvula protésica fue diagnosticada en 15 pacientes (13,8%), pero la más frecuente fue la relacionada con la coloniza-ción de dispositivos intracardíacos (51,4%), razón por la que el procedimiento quirúrgico más utilizado fue el cambio de sistema de estimulación. La principal indicación quirúrgica fue la infección incontrolada en 63 casos (57,8%), seguida por la insuficiencia cardíaca (38 pacientes; 34,9%) y en 67 casos (61,5%) los hemo-cultivos resultaron negativos. La sustitución de la válvula nativa por una prótesis mecánica se realizó en 28 pacientes (25,7%), de los cuáles 15 (13,8%) fueron en posición mitral. El recambio de una prótesis mecánica por otra de igual caracterís-ticas se llevó a cabo en 14 (12,8%) casos, 8 (7,3%) de ellos mitrales. La mortalidad global fue de 17,4%, más evidente en aquellos con endocarditis sobre válvula pro-tésica izquierda (7/15). Conclusiones: Predominaron el sexo masculino y la edad mayor de 60 años, así como la presencia de vegetaciones sobre dispositivos intracardíacos y los hemo-cultivos negativos. La endocarditis sobre válvula protésica se asoció significativamente con la mortalidad

Rara coincidencia de dos tumores, mixoma cardíaco e hipernefroma: presentación de un paciente.

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 asociación de dos tumores de diferente origen en un mismo paciente es cada vez más frecuente en la práctica clínica actual. Se presenta un caso con una rara asociación de mixoma cardíaco e hipernefroma, previamente tratado. Ante la presencia de manifestaciones neurológicas, inicialmente se planteó el diagnóstico de metástasis cerebral del tumor renal; luego, con el hallazgo ecocardiográfico de una masa intracardíaca, se pensó en la posibilidad de trombo, por lo que se decidió practicar cirugía cardíaca con carácter urgente para resecarla. El estudio anatomopatológico confirmó la existencia de un mixoma cardíaco, por lo que se trata de un enfermo con dos enfermedades tumorales cuya coincidencia ha sido pocas veces descrita

Initial presenting manifestations in 16,486 patients with inborn errors of immunity include infections and noninfectious manifestations

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
