Resumen

En el campo de la medicina las redes sociales han ganado poco a poco terreno y hoy en día juegan un rol importante en el aprendizaje y la enseñanza de conocimientos que se pueden trasmitir de inmediato y de forma masiva. El objetivo de este artículo es mostrar la experiencia colombiana en el uso de las redes sociales para crear aprendizaje quirúrgico significativo, con liderazgo y tutoría global. Se llevó a cabo un estudio descriptivo retrospectivo desde la creación de nuestras redes sociales en Twitter, 22 de febrero al 22 de agosto de 2019, evaluando las siguientes variables: número de tweets académicos, número de seguidores, impresiones, visitas y menciones. Desde la creación de nuestra red social Twitter @Cirbosque para realizar educación virtual quirúrgica a través de redes sociales con el fin de generar un aprendizaje significativo en nuestros seguidores, en solo seis meses del proyecto, seguimos a 62 cuentas, hemos realizado hasta la fecha 5.025 tweets académicos, con un crecimiento del 77,1% mensual, con 2.203 seguidores, con un crecimiento del 426 seguidores mensual, 1.090.000 impresiones, con un crecimiento del 56% mensual, 13.500 mil visitas, con un crecimiento del 28,9% mensual y 2.028 menciones, con un crecimiento del 88,3% mensual.

Aunque la evidencia aún es insuficiente para garantizar que la educación que se hace a través de redes sociales y de @Cirbosque sea eficiente, el impacto que ha tenido esta iniciativa en Twitter es apreciada por muchos cirujanos a nivel mundial incluyendo a grandes maestros referentes en cada uno de los temas que se han tratado, de la misma forma, la cantidad de participantes en las diversas discusiones planteadas día a día y con un incremento en todos los indicadores de impacto según Twitter Analytics, se puede deducir que el mensaje educativo está teniendo un efecto positivo y está llegando a miles de personas a nivel mundial.

Constraining Orbital Periods from Nonconsecutive Observations: Period Estimates for Long-period Planets in Six Systems Observed by K2 During Multiple Campaigns
Authors: Dholakia S. , Dholakia S. , Mayo Andrew W. , Dressing Courtney D. 
Published: February 2020

Abstract
Most planetary discoveries with the K2 and Transiting Exoplanet Survey Satellite (TESS) missions are restricted to short periods because of the limited duration of observation. However, the re-observation of sky area allows for the detection of longer period planets. We describe new transits detected in six candidate planetary systems that were observed by multiple K2 mission campaigns. One of these systems is a multiplanet system with four candidate planets; we present new period constraints for two planets in this system. In the other five systems, only one transit is observed in each campaign, and we derive period constraints from this new data. The period distributions are highly multimodal resulting from missed potential transits in the gap between observations. Each peak in the distribution corresponds to transits at an integer harmonic of the two observed transits. We further detail a generalized procedure to constrain the period for planets with multiple observations with intervening gaps. Because long-period photometrically discovered planets are rare, these systems are interesting targets for follow-up observations and confirmation. Specifically, all six systems are bright enough (V = 10.4–12.7) to be amenable to radial velocity follow-up. This work serves as a template for period constraints in a host of similar yet-to-be-discovered planets in long baseline, temporally gapped observations conducted by the TESS mission.

Using the gamma-ray luminosity functions for blazars, including flat-spectrum radio quasars (FSRQs) and BL Lac objects, as well as the Fermi-LAT detection efficiency, we estimate contributions from blazars resolved by Fermi-LAT as well as the unresolved counterpart. Combining the existing upper limits from stacking analyses, the cumulative neutrino flux from all blazars (including Fermi-LAT resolved and unresolved ones) are constrained in the range 0 ≲ γ
lw ≲ 2.5. We also evaluate the effects of the redshift evolution and the effective local number densities for each class of FSRQs, BL Lacs, and all blazars, on which we place another type of constraints on the blazar contribution using the nondetection of high-energy neutrino multiplets. We demonstrate that these two upper limits are complementary, and that the joint consideration of the stacking and multiplet analyses not only supports the argument that blazars are disfavored as the dominant sources of the 100 TeV neutrino background, but also extends it by including Fermi-LAT-unresolved blazars as well, for a more generic luminosity correlation

Abstract
The detailed magnetic field structure of the starless dense core CB81 (L1774, Pipe 42) in the Pipe Nebula was determined based on near-infrared polarimetric observations of background stars to measure dichroically polarized light produced by magnetically aligned dust grains in the core. The magnetic fields pervading CB81 were mapped using 147 stars and axisymmetrically distorted hourglass-like fields were identified. On the basis of simple 2D and 3D magnetic field modeling, the magnetic inclination angles in the plane-of-sky and line-of-sight directions were determined to be 4° ± 8° and 20° ± 20°, respectively. The total magnetic field strength of CB81 was found to be 7.2 ± 2.3 μG. Taking into account the effects of thermal/turbulent pressure and magnetic fields, the critical mass of CB81 was calculated to be M
cr = 4.03 ± 0.40 M
⊙, which is close to the observed core mass of M
core = 3.37 ± 0.51 M
⊙. We thus conclude that CB81 is in a condition close to the critical state. In addition, a spatial offset of 92″ was found between the center of the magnetic field geometry and the dust extinction distribution; this offset structure could not have been produced by self-gravity. The data also indicate a linear relationship between polarization and extinction up to A

V
∼ 30 mag going toward the core center. This result confirms that near-infrared polarization can accurately trace the overall magnetic field structure of the core.
Relation perçue entre l’utilisation de technologies d’aide et la perception de soi, le sentiment d’efficacité personnelle et l’anxiété aux évaluations en situation d’écriture

Published: February 2020

Nombre d’élèves éprouvent d’importantes difficultés en production écrite. Parmi les facteurs aggravants, notons la dyslexie/dysorthographie. L’utilisation des Technologies d’aide (Td’A) comme mesure d’adaptation au développement des compétences rédactionnelles chez ces élèves est alors fortement recommandée. Cette recherche longitudinale examine les apports et les limites des Td’A en écriture sur la perception de soi, le sentiment d’efficacité personnelle et l’anxiété aux évaluations d’élèves dyslexiques/dysorthographiques (N = 27) âgés de 12 à 13 ans. Tant au début qu’à la fin de l’année scolaire, les résultats indiquent que les élèves ayant la possibilité d’utiliser une Td’A en situation d’écriture manifestent une perception de soi et un sentiment d’efficacité personnelle significativement plus élevés que lorsqu’ils en sont privés. De plus, son utilisation s’avère prometteuse puisqu’elle est associée à moins d’anxiété aux évaluations aux deux temps de mesure. Les résultats obtenus sont discutés en lien avec des actions à encourager dans les écoles.
Simulation: Not Just a Manikin
Authors: Seropian Michael A. , Brown Kimberly , Gavilanes Jesika Samuelson , Driggers Bonnie 
Published: February 2020

Simulation education is currently flourishing in the United States and around the world. Simulation technology has improved, and its costs have dropped. When faced with demands for more accountability for quality education and increased enrollment, disciplines and specialties are embracing the idea of simulation as a valuable tool. Frequently, institutions develop simulation programs based on a narrow understanding of the technology and teaching potential of this tool. The purchase of simulation equipment often precedes the development of a sound program “vision” and plan. Only after understanding the tools and equipment can a meaningful plan be developed.
This article introduces and clarifies the different types of simulation equipment, and attempts to make sense of the roles and limitations of these technologies. It is through this knowledge that educators and program directors can best develop programs that are educationally meaningful. Similarly, a good understanding of simulation technology and terminology will likely lead to more thoughtful and cost-effective purchases.
Long-term Outcomes After LASIK Using a Hybrid Bi-aspheric Micro-monovision Ablation Profile for Presbyopia Correction
Authors: Luger Michiel H.A. , McAlinden Colm , Buckhurst Phillip J. , Wolffsohn James S. , Verma Shwetabh , Arba-Mosquera Samuel 
Published: February 2020

PURPOSE:
To evaluate visual outcomes 6 years after hybrid bi-aspheric multifocal central laser in situ keratomileusis for presbyopia correction (PresbyLASIK) treatments.

METHODS:
Thirty-eight eyes of 19 patients consecutively treated with central PresbyLASIK were assessed. The mean age of the patients was 51 ± 3 years at the time of treatment with a mean spherical equivalent refraction of −0.57 ± 1.98 diopters (D) and mean astigmatism of 0.58 ± 0.57 D. Monocular corrected distance visual acuity (CDVA), corrected near visual acuity (CNVA), and distance-corrected near visual acuity (DCNVA), uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), distance-corrected intermediate visual acuity (DCIVA), and uncorrected near visual acuity (UNVA) were assessed preoperatively and postoperatively for the dominant eye, non-dominant eye, and binocularly. Subjective quality of vision and near vision were assessed using the 10-item, Rasch-scaled, Quality of Vision (QoV) Questionnaire and Near Activity Visual Questionnaire (NAVQ), respectively.

RESULTS:
At 6 years postoperatively, mean binocular UDVA was 20/18 ± 4 and mean binocular UNVA and UIVA were 0.11 ± 0.13 and −0.08 ± 0.08 logRAD, respectively. Spherical equivalent showed a slow hyperopic drift of +0.10 D per year with refractive astigmatism stable from 6 weeks postoperatively. Defocus curves showed an improvement of 0.4 Snellen lines at best focus from 1 to 6 years of follow-up, reaching preoperative levels. Compared to the preoperative status, the corneal and ocular spherical aberrations (at a 6-mm diameter) decreased and were stable from 3 months of follow-up. Questionnaires revealed a postoperative unaided QoV score comparable to preoperative scores and with an improved postoperative unaided NAVQ score compared to preoperative scores with best correction.

CONCLUSIONS:
Presbyopic treatment using a hybrid bi-aspheric micro-monovision ablation profile is safe and efficacious even after 6 years postoperatively. The postoperative outcomes indicate improvements in binocular vision at far, intermediate, and near distances. An 8% re-treatment rate should be considered to increase satisfaction levels, including a 3% reversal rate.

Brain Mapping Performance as an Occupational Therapy Assessment Aid in Attention Deficit Hyperactivity Disorder
Authors: Chatthong Winai , Khemthong Supalak , Wongsawat Yodchanan 
Published: February 2020

Abstract
Importance: Brain mapping performance (BMP) may provide strong predictors to analyze primary functional outcomes and support occupational therapy with clients with attention deficit hyperactivity disorder (ADHD).
Objective: To clarify the value of quantitative electroencephalography to indicate BMP in children with ADHD.
Design: One-year cross-sectional study.
Setting: Brain Computer Interface Laboratory, Mahidol University, Salaya, Nakhon Pathom, Thailand.
Participants: Thai school-age children with and without ADHD (N = 305).
Outcomes and Measures: We used θ relative power in concordance with stepwise multiple regression analysis. Outcomes included measures of 12 brain locations that were compared between children with and without ADHD.
Results: Significant differences were found between the groups, especially for Cz, T3, Fp1, Fz, F4, and F7. According to BMP, the group with ADHD had higher emotional awareness and language comprehension than the group without ADHD.
Conclusions and Relevance: Occupational therapy practitioners can use BMP as a valuable tool for setting occupational goals to help children with ADHD improve their social–emotional learning performance in school and in the community. BMP may provide an evaluation to support occupational therapy services for clients with ADHD. The result can be applied in clinical settings by quantitative electroencephalography training.
What This Article Adds: BMP can be used as a neuropsychological and behavioral assessment tool for setting SMART (specific, measurable, attainable, relevant, and time-oriented) goals for occupational therapy services for clients with ADHD.
Adolescentes Usuários de Drogas e a Desinserção Social
Authors: Da Silva Januzzi Monica Eulália , Franco Ferrari Ilka 
Published: February 2020

O texto em questão buscou responder como as dificuldades de adesão ao tratamento, apresentadas por adolescentes usuários de drogas, podem beneficiar o trabalho realizado nos Centros de Atenção Psicossocial Infanto-Juvenill (CAPSi) do estado de Minas Gerais. Nele se destaca, entre outras, a dificuldade que se chamou de desinserção social. O campo teórico/prático da psicanálise orientou o trabalho através do método do caso único, que permite resultados universalizados respeitando as singularidades, isto é, um universal alcançado a partir do singular. Fragmentos das entrevistas semiestruturadas realizadas com os cinco jovens estudados, indicados pelas equipes dos serviços por serem considerados paradigmáticos daqueles que apresentavam dificuldades de adesão, e com os profissionais que os acompanharam são utilizados para subsidiar as considerações apresentadas, considerando a cartografia própria da vida dos sujeitos implicados no processo. Constatou-se que os efeitos das destituições simbólicas do Outro, no contemporâneo, têm favorecido a instauração de modos subjetivos de desconexão social, a exemplo da toxicomania, e que o modo como a desinserção aparece, na singularidade de cada caso, no contexto da adolescência, indica a presença de um sintoma social da época. A descrença dos jovens na relação com o Outro Social aparece em suas relações com o CAPSi, um Outro Institucional. Mas, quando esse Outro se faz exceção e se apresenta como lugar de cuidado, de presença e interesse pelo sujeito, mudanças ocorrem entre a desinserção e a inserção possível, levando o sujeito a encontrar um lugar no Outro, não se apagando no coletivo da política pública.
Albert Einstein en Nederlandse christen-pacifisten: samenwerking en breuk
Authors: Noordegraaf Herman 
Published: February 2020

Summary
Albert Einstein (1879-1955) was a left wing public intellectual, who was involved in societal issues, especially questions of peace and war. Adhering a pacifist view, he supported refusal of military service from the midst of the twentieth century. The pacifist peace movement welcomed the views of this famous scientist. This article describes and analyses the reception of Einstein within the Dutch Christian-pacifist organization Church and Peace (Kerk en Vrede). First, attention is given to Einstein’s views and actions regarding refusal of military service, as can be found in the periodical Kerk en Vrede. Secondly, the contacts will be described between the secretary of Church and Peace, Rev. J.B.Th. Hugenholtz, and Einstein. Hugenholtz wanted his support to realize a ‘Peace House’ of pacifist organizations in The Hague. Einstein reacted positively on this request. However, after Hitler came to power in January 1933 Einstein changed his mind. He did not support refusal of military service any longer. This led to a rupture between Einstein and the pacifist peace organizations. Within Church and Peace especially chairman G.J. Heering criticized him sharply. Here the roads parted in a fundamental way.

Abstract. The southeast Atlantic (SEA) region is host to a climatologically significant
biomass burning aerosol layer overlying marine stratocumulus. We present the
first results of the directly measured above-cloud aerosol optical depth (ACAOD)
from the recent ObseRvations of Aerosols above CLouds and their intEractionS
(ORACLES) airborne field campaign during August and September 2016. In our
analysis, we use data from the Spectrometers for Sky-Scanning Sun-Tracking
Atmospheric Research (4STAR) instrument and found an average ACAOD of 0.32
at 501 nm (range of 0.02 to 1.04), with an average Ångström exponent
(AE) above clouds of 1.71. The AE is much lower at 1.25 for the full column
(including below-cloud-level aerosol, with an average of 0.36 at 501 nm and
a range of 0.02 to 0.74), indicating the presence of large aerosol
particles, likely marine aerosol, in the lower atmospheric column. The ACAOD is
observed from 4STAR to be highest near the coast at about 12∘ S,
whereas its variability is largest at the southern edge of the average
aerosol plume, as indicated by 12 years of MODIS observations. In comparison
to MODIS-derived ACAOD and long-term fine-mode plume-average AOD along a
diagonal routine track extending out from the coast of Namibia, the
directly measured ACAOD from 4STAR is slightly lower than the ACAOD product
from MODIS. The peak ACAOD expected from MODIS AOD retrievals averaged over
a long term along the routine diagonal flight track (peak of 0.5) was
measured to be closer to coast in 2016 at about 1.5–4∘ E, with 4STAR ACAOD averages showing a peak of 0.42. When
considering the full observation set over the SEA, by spatially binning each
sampled AOD, we obtain a geographically representative mean ACAOD of 0.37.
Vertical profiles of AOD showcase the variability in the altitude of the
aerosol plume and its separation from the cloud top. We measured larger AOD at a
high altitude near the coast than farther from the coast, while generally
observing a larger vertical gap farther from the coast. Changes in AOD with
altitude are correlated with carbon monoxide, a gas tracer of the biomass
burning aerosol plume. Vertical extent of gaps between aerosol and cloud
show a wide distribution, with a near-zero gap being most frequent. The gap
distribution with longitude is observed to be largest at about 7∘ E, farther from coast than expected from previous studies.
