Apoio social percebido por gestantes de Santa Marta, Colômbia: uma análise comparativa

Introduction: Perceived social support during gestation is important for perinatal mental health. However, little is known about these variables in the Colombian population. Objetive: To compare perceived social support with sociodemographic and gynaeco-obstetric variables and positive affect in pregnant women in Santa Marta, Colombia. Materials and Methods: Forty women between 19 and 41 years of age (M=26.48; SD=5.03), in their third trimester of pregnancy and beneficiaries of a program to promote exclusive breastfeeding, participated. The participants filled out a sociodemographic and gynaeco-obstetric form, the Multidimensional Scale of Perceived Social Support (MSPSS) (α=0.88), and a subscale of the Positive and Negative Affect Schedule (PANAS) (α=0.82). The Mann-Whitney U test was used for comparative statistical analyses. Ethical guidelines for human research were followed. Results: 67% of the participants belonged to a low socioeconomic status, 87.5% had a partner, 67.5% had a higher education, 42.5% were employed, and 47.5% were new mothers. Women of higher socioeconomic status perceived greater social support from their friends (p = 0.01). Family social support was significantly higher in first-time mothers (p=0.01) and mothers who reported higher positive affect (p = 0.03). Finally, social support from significant others was higher when it was the woman’s first pregnancy (p=0.02). Conclusions: Significant differences were found in some dimensions of perceived social support according to socioeconomic status, being a first-time mother, and positive affect. Further studies with larger sample sizes are recommended.

El afecto positivo favorece la estimulación de emociones placenteras en el embarazo y proporciona a la madre un ambiente de tranquilidad y alegría, que se traduce en mayor bienestar. Las mujeres con nivel adquisitivo alto pueden acceder a los servicios de salud mediante sus vínculos personales y redes de apoyo, lo que provoca una mayor disponibilidad de recursos psicosociales. En la primera gestación, los padres suelen desplegar un portafolio de comportamientos protectores hacia la mujer, que sirven como apoyo durante el proceso y, al mismo tiempo, mitigan la incertidumbre. Introducción: El apoyo social percibido durante la gestación es importante para la salud mental perinatal. Sin embargo, poco se conoce sobre estas variables en la población colombiana. Objetivo: Comparar el apoyo social percibido según variables sociodemográficas, ginecobstétricas y afecto positivo en mujeres gestantes de Santa Marta, Colombia. Materiales y métodos: Participaron 40 mujeres entre 19 y 41 años (M=26.48; DE=5.03), que se encontraban en su tercer trimestre de embarazo, beneficiarias de un programa de promoción de la lactancia materna exclusiva. Las participantes diligenciaron una ficha de información sociodemográfica y ginecobstétrica, la Escala Multidimensional de Apoyo Social Percibido (α=0.88) y una subescala de la Escala de Afectos Positivos y Negativos (α=0.82). Se aplicó la prueba U de Mann-Whitney para los análisis estadísticos comparativos y se siguieron los lineamientos éticos en investigación con humanos. Resultados: 67% de las participantes fueron de estrato socioeconómico bajo, 87.5% tenía pareja, 67.5% contaba con estudios superiores, 42.5% tenía trabajo y 47.5% eran madres primerizas. Las mujeres de estrato socioeconómico alto percibieron mayor apoyo social por parte de sus amigos (p=0.01). El apoyo social familiar fue significativamente más alto en las madres primerizas (p=0.01) y en las que reportaron mayor afecto positivo (p=0.03). Por último, el apoyo social por parte de personas significativas fue mayor cuando era el primer embarazo de la mujer (p=0.02). Conclusión: Se encontraron diferencias significativas en algunas dimensiones del apoyo social percibido según el estrato socioeconómico, ser madre primeriza y el afecto positivo. Se recomienda realizar otros estudios con mayor tamaño muestral.

Separation of track- and shower-like energy deposits in ProtoDUNE-SP using a convolutional neural network

International audienceLiquid argon time projection chamber detector technology provides high spatial and calorimetric resolutions on the charged particles traversing liquid argon. As a result, the technology has been used in a number of recent neutrino experiments, and is the technology of choice for the Deep Underground Neutrino Experiment (DUNE). In order to perform high precision measurements of neutrinos in the detector, final state particles need to be effectively identified, and their energy accurately reconstructed. This article proposes an algorithm based on a convolutional neural network to perform the classification of energy deposits and reconstructed particles as track-like or arising from electromagnetic cascades. Results from testing the algorithm on experimental data from ProtoDUNE-SP, a prototype of the DUNE far detector, are presented. The network identifies track- and shower-like particles, as well as Michel electrons, with high efficiency. The performance of the algorithm is consistent between experimental data and simulation

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 $\times$ 6 $\times$ 6 m$^3$ liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019–2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches.
