La imagen y la narrativa como herramientas para el abordaje psicosocial en escenarios de violencia. Departamento de Cundinamarca.

Colombia a través de su historia ha vivido el flagelo del conflicto armado, el cual al principio estuvo relacionado con los poderes políticos y los pensamientos ideológicos, pero con el pasar del tiempo se vieron involucrados otros actores radicales como las Farc quienes perdieron por completo su ideología; la cual se centraba en pelear por la desigualdad social y su principal objetivo se convirtió en la toma del poder, promoviendo una violencia obligada que desbordó todo su accionar contra la población civil con prácticas como las masacres, violaciones, reclutamiento forzado, apropiación de tierras y terminando en los desplazamientos de campesinos a lugares desconocidos, donde tenían que sufrir la discriminación y exclusión de una sociedad en muchos casos indolente. Por tal razón en este trabajo se reflexiona sobre la situación de las víctimas que padecieron las inclemencias de la violencia y se hace un análisis de las narrativas de muchos testigos directos que tuvieron la valentía de contar sus historias llenas de miedo, angustia, desolación y tristeza, pero también de fortaleza y esperanza porque a pesar de la crudeza de las situaciones que vivieron fueron capaces de participar en un proceso de reconstrucción de memoria, donde comprendieron que pasar la página no era la mejor opción y se dieron la oportunidad de encontrar una reparación simbólica del daño causado. Sin lugar a dudas la violencia arrasa consigo a las sociedades en general, dado que sus huellas en muchas ocasiones son irreparables; puesto que muchas familias son desintegradas, las comunidades se ven forzadas a migrar a otras regiones, mujeres niñas y niños son abusados sexualmente; entre otros, sin embargo se debe hacer énfasis en que estas personas merecen una nueva vida, nuevas oportunidades… por tal razón es necesario trabajar en pro del restablecimiento de los derechos de las víctimas. Es por esto que a partir de nuestro aprendizaje, en este trabajo también se hace mención de algunas acciones psicosociales con estás víctimas del conflicto armado; donde comprendemos la importancia de reconocer cada particularidad de las víctimas y de la realidad que vivieron, para así lograr un proceso que permita contribuir a la superación de los impactos emocionales y sociales que causaron estás experiencias en cada uno de ellos, facilitando la proyección de explicaciones con nuevas miradas hacía el futuro, donde la reparación integral sea el factor más importante dentro de estas acciones psicosociales y les permita una reconstrucción de sus proyectos de vida. Cabe mencionar que para realizar estas acciones psicosociales es importante problematizar la realidad social con las mismas víctimas, quienes son poseedoras de esas historias y nos pueden orientar y proponer alternativas que nos posibiliten fortalecer las acciones psicosociales, de tal forma que se logre ir más allá del cumplimiento de los objetivos que se desean alcanzar con estos acompañamientos.Colombia through its history has lived the scourge of armed conflict, which at the beginning was related with political powers and ideological thoughts, but with the time, they were involved other radical groups like Las Farc who completely lost their ideology; which focused on fighting for social inequality, and its main objective became the seizure of power, they promoted a forced violence that overflowed all their actions against the civilian population with practices such as massacres, rapes, forced recruitment, land appropriation ended with displacement of peasants to unknown places, where they had to suffer discrimination and exclusion from a indolent society in many cases. For this reason, this work reflects on the situation of the victims who suffered the inclemency of violence, and an analysis of the narratives of many direct witnesses is made who had the courage to tell their stories full of fear, anguish, desolation and sadness, but also of strength and hope because despite the harshness of the situations they lived, they were able to participate in a process of memory reconstruction, where they understood that turning the page was not the best option, and they gave themselves the opportunity to find a symbolic repair of the damage caused. Undoubtedly, violence devastates societies, since their footprints are often irreparable; due to many families are disintegrated, communities are forced to migrate to other regions, women girls and boys are sexually abused; among others, However, it should be emphasized that these people deserve a new life, new opportunities… For this reason it is necessary to work for the restoration of the rights of the victims. That is why, from our learning, this work also mentions some psychosocial actions with these victims of the armed conflict; where we understand the importance of recognizing each particularity of the victims and the reality they lived, in order to achieve a process that helps to overcome the emotional and social impacts that caused these experiences in each of them, facilitating the projection of explanations with new looks towards the future, where integral reparation is the most important factor in these psychosocial actions and allows them to rebuild their life projects. It is worth mentioning that in order to carry out these psychosocial actions it is important to problematize social reality with the same victims, who are possessors of these stories and can guide us and propose alternatives that allow us to strengthen psychosocial actions, so that we can go beyond fulfillment of the objectives you wish to achieve with these accompaniment

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.

Management of acute diverticulitis with pericolic free gas (ADIFAS). an international multicenter observational study

Background: There are no specific recommendations regarding the optimal management of this group of patients. The World Society of Emergency Surgery suggested a nonoperative strategy with antibiotic therapy, but this was a weak recommendation. This study aims to identify the optimal management of patients with acute diverticulitis (AD) presenting with pericolic free air with or without pericolic fluid. Methods: A multicenter, prospective, international study of patients diagnosed with AD and pericolic-free air with or without pericolic free fluid at a computed tomography (CT) scan between May 2020 and June 2021 was included. Patients were excluded if they had intra-abdominal distant free air, an abscess, generalized peritonitis, or less than a 1-year follow-up. The primary outcome was the rate of failure of nonoperative management within the index admission. Secondary outcomes included the rate of failure of nonoperative management within the first year and risk factors for failure. Results: A total of 810 patients were recruited across 69 European and South American centers; 744 patients (92%) were treated nonoperatively, and 66 (8%) underwent immediate surgery. Baseline characteristics were similar between groups. Hinchey II-IV on diagnostic imaging was the only independent risk factor for surgical intervention during index admission (odds ratios: 12.5, 95% CI: 2.4-64, P =0.003). Among patients treated nonoperatively, at index admission, 697 (94%) patients were discharged without any complications, 35 (4.7%) required emergency surgery, and 12 (1.6%) percutaneous drainage. Free pericolic fluid on CT scan was associated with a higher risk of failure of nonoperative management (odds ratios: 4.9, 95% CI: 1.2-19.9, P =0.023), with 88% of success compared to 96% without free fluid ( P <0.001). The rate of treatment failure with nonoperative management during the first year of follow-up was 16.5%. Conclusion: Patients with AD presenting with pericolic free gas can be successfully managed nonoperatively in the vast majority of cases. Patients with both free pericolic gas and free pericolic fluid on a CT scan are at a higher risk of failing nonoperative management and require closer observation

Searching for dark matter annihilation in recently discovered Milky Way satellites with Fermi-LAT

We search for excess γ-ray emission coincident with the positions of confirmed and candidate Milky Way satellite galaxies using six years of data from the Fermi Large Area Telescope (LAT). Our sample of 45 stellar systems includes 28 kinematically confirmed dark-matter-dominated dwarf spheroidal galaxies (dSphs) and 17 recently discovered systems that have photometric characteristics consistent with the population of known dSphs. For each of these targets, the relative predicted γ-ray flux due to dark matter annihilation is taken from kinematic analysis if available, and estimated from a distance-based scaling relation otherwise, assuming that the stellar systems are DM-dominated dSphs. LAT data coincident with four of the newly discovered targets show a slight preference (each ~2σ local) for γ-ray emission in excess of the background. However, the ensemble of derived γ-ray flux upper limits for individual targets is consistent with the expectation from analyzing random blank-sky regions, and a combined analysis of the population of stellar systems yields no globally significant excess (global significance 1 TeV and mDM,t+t-> 70 GeV) and weakening by a factor of ~1.5 at lower masses relative to previously observed limits

A systematic review of progranulin concentrations in biofluids in over 7,000 people—assessing the pathogenicity of GRN mutations and other influencing factors

Background: Pathogenic heterozygous mutations in the progranulin gene (GRN) are a key cause of frontotemporal dementia (FTD), leading to significantly reduced biofluid concentrations of the progranulin protein (PGRN). This has led to a number of ongoing therapeutic trials aiming to treat this form of FTD by increasing PGRN levels in mutation carriers. However, we currently lack a complete understanding of factors that affect PGRN levels and potential variation in measurement methods. Here, we aimed to address this gap in knowledge by systematically reviewing published literature on biofluid PGRN concentrations. Methods: Published data including biofluid PGRN concentration, age, sex, diagnosis and GRN mutation were collected for 7071 individuals from 75 publications. The majority of analyses (72%) had focused on plasma PGRN concentrations, with many of these (56%) measured with a single assay type (Adipogen) and so the influence of mutation type, age at onset, sex, and diagnosis were investigated in this subset of the data. Results: We established a plasma PGRN concentration cut-off between pathogenic mutation carriers and non-carriers of 74.8 ng/mL using the Adipogen assay based on 3301 individuals, with a CSF concentration cut-off of 3.43 ng/mL. Plasma PGRN concentration varied by GRN mutation type as well as by clinical diagnosis in those without a GRN mutation. Plasma PGRN concentration was significantly higher in women than men in GRN mutation carriers (p = 0.007) with a trend in non-carriers (p = 0.062), and there was a significant but weak positive correlation with age in both GRN mutation carriers and non-carriers. No significant association was seen with weight or with TMEM106B rs1990622 genotype. However, higher plasma PGRN levels were seen in those with the GRN rs5848 CC genotype in both GRN mutation carriers and non-carriers. Conclusions: These results further support the usefulness of PGRN concentration for the identification of the large majority of pathogenic mutations in the GRN gene. Furthermore, these results highlight the importance of considering additional factors, such as mutation type, sex and age when interpreting PGRN concentrations. This will be particularly important as we enter the era of trials for progranulin-associated FTD.</p

The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra

This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17)

The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library (MaStar) accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) survey which publicly releases infra-red spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the sub-survey Time Domain Spectroscopic Survey (TDSS) data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey (SPIDERS) sub-survey and the eBOSS-RM program. Along with the primary data sets, DR17 includes 25 new or updated Value Added Catalogs (VACs). This paper concludes the release of SDSS-IV survey data. SDSS continues into its fifth phase with observations already underway for the Milky Way Mapper (MWM), Local Volume Mapper (LVM) and Black Hole Mapper (BHM) surveys
