The Family Context in Cybervictimization: A Systematic Review and Meta-Analysis.

The use of Information and Communication Technologies is clearly widespread among adolescents from a young age. Although it poses a significant contribution at the academic, social, and emotional levels, it can also involve a set of important risks, including cyberbullying and, therefore, cybervictimization. Previous studies have pointed out the importance of family context since parental control and family communication emerge as contributors to this phenomenon. Therefore, the aim of the present study was to analyze the influence of family communication on cybervictims and the moderating role of different sociodemographic variables (age, gender, nationality, and culture), as well as social, emotional, and personality variables. In this context, a meta-analysis was performed with a random effects model, using a total meta-sample of 29,093 adolescents (mean age: 14.50 years) distributed in k = 20 samples belonging to nine studies on cybervictimization published in English in Q1 journals between 2015 and 2020. The results showed that family offensive communication is related to cybervictimization. This could be because the affected individuals often use social media to compensate for the deficiencies they perceive within their families, as well as to obtain support, which increases their time spent on the Internet and their exposure to this phenomenon. These findings highlight the need for family and community interventions, not only school-based or individual interventions.

Perception of Social and Educational Quality of Life of Minors Diagnosed with Rare Diseases: A Systematic Review and Meta-Analysis.

This study explores the perception of social and educational quality of life in minors with rare diseases (RDs). Two meta-analyses were performed, applying the random effects model. Results: Regarding the social Quality of Life, the meta-sample consisted of k = 40 samples, with a total population of 1943 children (mean age = 9.42 years), of whom 687 (35.3%) were girls, 615 (31.4%) were boys and 641 (33%) did not report their sex. The effect size was large (mean size = 7.68; p < 0.000; 99% Confidence Interval; lower limit = 7.22; upper limit = 8.14). The results of the meta-regression and model analysis showed the importance of the measurement instrument (Paediatric Quality-of-Life Inventory and Prototypes of the Quality of life) and the dissimilarity of perception among caregivers. The nationality and the type of RD were not relevant. With respect to the educational Quality of Life, the meta-sample consisted of k = 19 samples, with 699 minors (mean age = 10.3 years), of whom 266 (38%) were girls, 242 (34.6%) were boys and 191 (27.4%) did not report their sex. The effect size was large (mean size = 7.15; p < 0.000; 99% CI; lower limit = 6.35; upper limit = 7.94). The meta-regression and comparison of models showed that the type of RD was essential. The measurement instrument was a moderating variable, especially the Parent version Paediatric Quality-of-Life Inventory. This study reveals the need for further research on RDs and their social−educational effects.

Origen de la arteria femoral profunda como referencia para ligadura y profundoplastías / Origin of the femoral deep artery as a reference for ligation and surgery

El presente estudio se llevó a cabo para investigar las variaciones en el origen de la arteria femoral profunda, por debajo del arco femoral en cadáveres a 2.300 m.s.n.m., en comparación con las estadísticas que menciona Testut y Jacob, de los investigadores Quain y Viguerie, con la finalidad de ligar la arteria femoral en importantes casos correspondientes y como guía de referencia para profundoplastías. Se midieron 19 cadáveres y en ambos lados (38 observaciones) en los anfiteatros del Departamento de Morfología Humana de la Universidad Nacional de San Agustín de Arequipa
