Correlación entre conductas sobre sexting y dependencia al móvil en estudiantes de enfermería

Introduction. Sexting is defined as the sending of erotic or pornographic content through digital devices; It’s a term of daily use whose practice may bring positive effects, and on the other hand risks for sexual and mental health as shown in different studies. Regarding mobile dependency, this practice has increased in university students, who need to create, share, and download content. Both phenomena have factors in common that may signify an unexplored relationship. Objective. To determine the correlation between sexting behaviors mobile phone dependency in nursing college students. Methodology. This is an observational, cross-sectional, and correlational study, with a non-probabilistic convenience sampling method that included undergraduate nursing students at a public university in Mexico, the Pearson and Spearman correlation was used on the results of the totals and components of the instruments: behaviors on sexting and Mobile Dependency Test. Results. With 300 participants, it is reported that 64.7% declare having participated in sexting through text messages, sharing images, among other forms of participation; On the other hand, in terms of mobile phone dependency, 96.3% were in a medium and high dependency. When comparing the final summations of each instrument, a positive correlation is obtained with r.=0.166, p<0.050. Conclusion. A positive correlation between sexting and mobile phone dependency is the first indicator to explore in-depth the common factors that predispose and that can derive from both phenomena in the young population.Introducción. El sexting se define como el envío de contenido erótico o pornográfico a través de dispositivos digitales; es un término de uso cotidiano, cuya práctica puede traer efectos positivos, y por otro lado riesgos para la salud sexual y mental en quienes lo practican. En lo que respecta a la dependencia al móvil, esta práctica se ha incrementado en estudiantes universitarios, quienes tienen la necesidad de crear, compartir y descargar contenidos. Ambos fenómenos tienen factores en común que pueden significar una relación no explorada. Objetivo. Determinar la correlación entre las conductas sobre el sexting y la dependencia al móvil en estudiantes de enfermería. Metodología. Estudio observacional, transversal y correlacional, con muestreo no probabilístico a conveniencia que incluyó estudiantes del grado en enfermería en una universidad pública de México, se utilizó la correlación de Pearson y Spearman sobre los resultados de los totales y componentes de los instrumentos: conductas sobre sexting y Test de Dependencia al móvil. Resultados. Con 300 participantes, se reporta que el 64.7% declara haber participado en el sexting a través de mensajes de texto, compartir imágenes, entre otras formas de participación; por otro lado, en cuanto a la dependencia al móvil el 96.3% se encontraba en una dependencia media y alta. Al comparar las sumatorias finales de cada instrumento se obtiene una correlación positiva con r.=0.166, p<0.050. Conclusión. Una correlación positiva entre el sexting y la dependencia al móvil es un primer indicador para explorar a profundidad los factores en común que predisponen y que pueden derivar de ambos fenómenos en la población joven

Propuesta educativa para elevar los niveles de conocimiento sobre sexualidad en adolescentes síndrome de Down

RESUMEN Estudios recientes demuestran la importancia de educar la sexualidad en pacientes con síndrome de Down desde la infancia, con el propósito de darle respuesta a las curiosidades sexuales de la etapa, así como prepararlos para arribar a la adultez. A partir de esta afirmación, la presente investigación tuvo como objetivo general determinar el nivel de conocimientos de los adolescentes con síndromes de Down en relación con la sexualidad y crear un programa de intervención educativa, con el fin de propiciarles una sexualidad sana; para ello se escogieron 6 adolescentes de edades entre 10 y 15 años, pertenecientes a la escuela especial Francisco Vicente Agujera del municipio Manzanillo de la provincia Granma. Los referentes teóricos se apoyaron en una concepción humanista - desarrolladora y en la teoría del reforzamiento positivo. La estrategia estuvo en función del trabajo interrelacionado de los adolescentes con síndrome de Down. Se partió de las necesidades educativas arrojadas en el diagnóstico, se diseñó el programa con sus objetivos, posibilitó que estos adolescentes consoliden su identidad sexual, identificándose de acuerdo con su sexo, se incluyeron los genitales en su esquema corporal denominándolos, fomentaron hábitos de higiene relacionados con el cuidado del cuerpo y estimularon las relaciones afectivas a través de los juegos de roles. Se recomienda ampliar esta investigación, con seguimiento hasta la adultez y llevar a la comunidad una estrategia que sensibilice a sus integrantes con la sexualidad de los síndromes de Down. ABSTRACT Recent studies demonstrate the importance of educating sexuality in patients with Down syndrome since infancy, in order to respond to the sexual curiosities of the stage, as well as prepare them to reach adulthood. Based on this assertion, the present research had as general objective to determine the level of knowledge of the adolescents with Down syndromes in relation to the sexuality and to create a program of educational intervention, in order to propitiate them a healthy sexuality; six teenagers between 10 and 15 years of age, belonging to the Francisco Vicente Aguilera special school in the Manzanillo municipality of the Granma province were chosen. The theoretical references were based on a humanist - developmental conception and on the theory of positive reinforcement. The strategy was based on the interrelated work of adolescents with Down syndrome. It was based on the educational needs of the diagnosis, the program was designed with its objectives, enabled these adolescents to consolidate their sexual identity, identified according to their sex, included the genitals in their body schema, naming them, fostered related hygiene habits With the care of the body and stimulated the affective relations through the role plays. It is recommended to expand this research, with follow-up until adulthood and bring to the community a strategy that sensitizes its members with the sexuality of Down syndrome

Gender Differences in Patients Candidates for Bariatric Surgery: Anxiety, Depression and Causal Attributions

Objetivo. Analizar la relación entre las variables psicológicas tipo de atribución, sintomatología ansiosa y sintomatología depresiva en función del género en una muestra de pacientes con obesidad mórbida candidatos a cirugía bariátrica. Material y Métodos. Estudio observacional, transversal y unicéntrico. Se seleccionaron 259 pacientes candidatos a cirugía bariátrica del Hospital Universitario Virgen del Rocío, Sevilla. Se utilizaron plantillas para la recogida de datos sociodemográficos y clínicos, así como el instrumento validado Escala de Ansiedad y Depresión Hospitalaria. Resultados. En su mayoría, los pacientes realizaron atribuciones controlables, aunque las mujeres presentaron una mayor proporción de atribuciones incontrolables. En lo que respecta a la sintomatología ansiosa y depresiva, se encontró que los pacientes no aptos para la cirugía bariátrica presentaron mayores niveles de sintomatología ansiosa y depresiva. Además, apareció una tendencia a que mayores niveles de sintomatología ansiosa y depresiva estuvieran asociados a atribuciones de tipo controlable, lo que resulta controvertido atendiendo a la literatura disponible. Conclusiones. Este estudio muestra la importancia de continuar investigando acerca de distintas variables psicológicas para ajustar los tratamientos preoperatorios a las características de los pacientes, así como de realizar investigaciones que tengan en cuenta también medidas postoperatorias que permitan encontrar variables predictoras del éxito de las intervenciones.Objective. To analyze the relationship between the psychological variables type of attribution, anxiety and depressive symptoms according to gender in a sample of patients with morbid obesity who are candidates for bariatric surgery. Material and methods. Observational, cross-sectional and single-center study. 259 patients who were candidates for bariatric surgery were selected from the Virgen del Rocío University Hospital, Seville. Templates were used to collect sociodemographic and clinical data, as well as the validated Hospital Anxiety and Depression Scale instrument. Results. Most of the patients had controllable attributions, although women had a higher proportion of uncontrollable attributions. Regarding anxiety and depressive symptoms, it was found that patients ineligible for bariatric surgery presented higher levels of anxiety and depression. In addition, there was a tendency for higher levels of anxiety and depressive symptoms to be associated with controllable attributions, which is controversial based on the available literature

Genotyping, sequencing and analysis of 140,000 adults from Mexico City

The Mexico City Prospective Study is a prospective cohort of more than 150,000 adults recruited two decades ago from the urban districts of Coyoacán and Iztapalapa in Mexico City1. Here we generated genotype and exome-sequencing data for all individuals and whole-genome sequencing data for 9,950 selected individuals. We describe high levels of relatedness and substantial heterogeneity in ancestry composition across individuals. Most sequenced individuals had admixed Indigenous American, European and African ancestry, with extensive admixture from Indigenous populations in central, southern and southeastern Mexico. Indigenous Mexican segments of the genome had lower levels of coding variation but an excess of homozygous loss-of-function variants compared with segments of African and European origin. We estimated ancestry-specific allele frequencies at 142 million genomic variants, with an effective sample size of 91,856 for Indigenous Mexican ancestry at exome variants, all available through a public browser. Using whole-genome sequencing, we developed an imputation reference panel that outperforms existing panels at common variants in individuals with high proportions of central, southern and southeastern Indigenous Mexican ancestry. Our work illustrates the value of genetic studies in diverse populations and provides foundational imputation and allele frequency resources for future genetic studies in Mexico and in the United States, where the Hispanic/Latino population is predominantly of Mexican descent

The RESOLVE Survey Atomic Gas Census and Environmental Influences on Galaxy Gas Reservoirs

We present the H i mass inventory for the REsolved Spectroscopy Of a Local VolumE (RESOLVE) survey, a volume-limited, multi-wavelength census of >1500 z = 0 galaxies spanning diverse environments and complete in baryonic mass down to dwarfs of ~109 ${M}_{\odot }$. This first 21 cm data release provides robust detections or strong upper limits (1.4M H i 1012 ${M}_{\odot }$) halos, suggesting that gas stripping and/or starvation may be induced by interactions with larger halos or the surrounding cosmic web. We find that the detailed relationship between G/S and environment varies when we examine different subvolumes of RESOLVE independently, which we suggest may be a signature of assembly bias
