Racial/Ethnic Differences in the Benefit of Social Networks on Anxiety Symptoms
Anxiety is a pressing health concern, affecting 40 million adults in the United States every year. Interestingly, communities of color have lower rates of anxiety disorders relative to Non-Hispanic Whites, despite on average experiencing more lifetime adversity characteristic of members of marginalized groups, such as low socioeconomic status and discrimination. Research indicates that contact with one’s social network, particularly large, closely knit ones among Hispanics, are protective factors against anxiety. However, empirical investigations of racial/ethnic differences in the benefits of social networks on anxiety are lacking. Data from the Health and Retirement Study (HRS), a nationally representative sample of adults aged 51 and older in the United States, were used in this investigation. The 2010/2012 waves were used to include information pertaining to self-reported anxiety symptoms. Results from a weighted linear regression indicate that Non-Hispanic Blacks and Hispanics reported more anxiety symptoms relative to Non-Hispanic Whites after adjusting for age, sex, degree of education, and household wealth. Second, reporting more social contact with children and friends was related to less anxiety symptoms. Third, racial/ethnic differences in the effect of social networks on anxiety were found, in which time spent away from children was even more strongly related to anxiety among Hispanics relative to non-Hispanic Whites. Such results indicate that Hispanics may benefit more from increased social contact with their children relative to other racial/ethnic groups in protecting against anxiety, demonstrating the importance of nurturing social networks in order to reduce anxiety in this particularly vulnerable group
Validez del signo de Blumberg en relación con el estadio histopatológico del apéndice cecal en pacientes con apendicitis aguda en el Hospital Mario Gaitán Yanguas desde agosto de 2015 hasta abril de 2016
La apendicitis aguda es una entidad patológica que se presenta con una frecuencia importante en los servicios de urgencias en casi todos los niveles de atención hospitalaria. El diagnostico suele ser difícil de hacer en la primera valoración, lo que genera retrasos en el abordaje terapéutico oportuno. Partiendo de que el signo de Blumberg es el más utilizado en los servicios de urgencias, se ha querido estudiar y demostrar la validez para mejorar el diagnóstico de forma temprana de apendicitis aguda teniendo en cuenta la relación que se pueda presentar con el estadio histopatológico del apéndice cecal.
El objetivo de este trabajo es determinar la sensibilidad y especificidad del signo de Blumberg y su correlación con los estadios histopatológicos del apéndice cecal, para el diagnóstico temprano de apendicitis aguda en pacientes del Hospital Mario Gaitán Yanguas de Soacha en el periodo comprendido entre 2015 y 2016. La recolección de la información se realizó mediante la revisión de historias clínicas, previa autorización del hospital donde se tuvo en cuenta la documentación del
signo de Blumberg reportado como positivo o negativo y adicionalmente se revisó el reporte de patología de los pacientes que fueron intervenidos quirúrgicamente. Se tomó una muestra de 200 historias clínicas, de pacientes con diagnóstico de apendicitis aguda y que además tuvieran el reporte de la patología del tejido apendicular extraído, de los cuales solo 180 cumplieron con los criterios de inclusión propuestos en el trabajo. Dicha muestra fue dividida en dos grupos, un grupo de enfermos en donde se incluyeron los hallazgos histopatológicos
relacionados con apendicitis incipiente y edematosa. En el grupo control se incluyeron los hallazgos compatibles con apendicitis fibrinopurulenta, gangrenosa, perforada y plastrón. Estos hallazgos se compararon con el signo de Blumberg, encontrando una sensibilidad del 54.89% entre el grupo de enfermos y el grupo control con respecto a la positividad del signo de Blumberg y una especificidad del 53.19% con un valor predictivo positivo de 76.84% y un valor predictivo negativo de 29,41%. 8 Lo que demuestra lo anterior es que el signo tiene una alta sensibilidad para diagnosticar los estadios tempranos de la enfermedad según su estadio histopatológico temprano (incipiente, edematosa), pero mostro una especificidad
baja del 29.42% lo que indica que el hecho de que el signo de Blumberg sea negativo no descarta la progresión de la apendicitis aguda cuando curse con estadios histopatológicos tempranos.PregradoMédico(a) Cirujan
Multidrug resistant pulmonary tuberculosis treatment regimens and patient outcomes: an individual patient data meta-analysis of 9,153 patients.
Treatment of multidrug resistant tuberculosis (MDR-TB) is lengthy, toxic, expensive, and has generally poor outcomes. We undertook an individual patient data meta-analysis to assess the impact on outcomes of the type, number, and duration of drugs used to treat MDR-TB
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. DR14

Viral to metazoan marine plankton nucleotide sequences from the Tara Oceans expedition
A unique collection of oceanic samples was gathered by the Tara Oceans expeditions (2009–2013), targeting plankton organisms ranging from viruses to metazoans, and providing rich environmental context measurements. Thanks to recent advances in the field of genomics, extensive sequencing has been performed for a deep genomic analysis of this huge collection of samples. A strategy based on different approaches, such as metabarcoding, metagenomics, single-cell genomics and metatranscriptomics, has been chosen for analysis of size-fractionated plankton communities. Here, we provide detailed procedures applied for genomic data generation, from nucleic acids extraction to sequence production, and we describe registries of genomics datasets available at the European Nucleotide Archive (ENA, www.ebi.ac.uk/ena). The association of these metadata to the experimental procedures applied for their generation will help the scientific community to access these data and facilitate their analysis. This paper complements other efforts to provide a full description of experiments and open science resources generated from the Tara Oceans project, further extending their value for the study of the world’s planktonic ecosystems

Sloan Digital Sky Survey IV: mapping the Milky Way, nearby galaxies, and the distant universe
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July
The 13th Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey Mapping Nearby Galaxies at Apache Point Observatory
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2,MaNGA, and eBOSS. In addition, eBOSS contains two major subprograms: TDSS and SPIDERS. This paper describes the first data release from SDSS-IV, Data Release 13 (DR13), which contains new data, reanalysis of existing data sets and, like all SDSS data releases, is inclusive of previously released data. DR13 makes publicly available 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA,the first data released from this survey. It includes new observations from eBOSS, completing SEQUELS. In addition to targeting galaxies and quasars, SEQUELS also targeted variability-selected objects from TDSS and X-ray selected objects from SPIDERS. DR13 includes new reductions ofthe SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification. DR13 releases new reductions of the APOGEE-1data from SDSS-III, with abundances of elements not previously included and improved stellar parameters for dwarf stars and cooler stars. For the SDSS imaging data, DR13 provides new, more robust and precise photometric calibrations. Several value-added catalogs are being released in tandem with DR13, in particular target catalogs relevant for eBOSS, TDSS, and SPIDERS, and an updated red-clump catalog for APOGEE.This paper describes the location and format of the data now publicly available, as well as providing references to the important technical papers that describe the targeting, observing, and data reduction. The SDSS website, http://www.sdss.org, provides links to the data, tutorials and examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned ~6-year operations of SDSS-IV.PostprintPeer reviewe
