    (Elsevier Doyma, 2016-03) Campos-Jara, C.; Martínez-Salazar, C.; Carrasco-Alarcón, V.; Arcay-Montoya, R.; Ramírez-Campillo, R.; Mariscal-Arcas, M.; Jerez-Mayorga, D.; Da Silva-Grigoletto, M.E.
    Objetivo: Comparar el efecto de 2 métodos de electroestimulación en las siguientes variables: fuerza y antropometría. Método: Se realizó una investigación experimental, aleatoria y simple ciego. Se evaluó a 18 sujetos, distribuidos en: Grupo Corriente TENS Modificada (CTM: n = 6), Grupo Corriente Rusa (CR: n = 6) y Grupo Control (TC: n = 6, sometido a corriente TENS Convencional, considerada en la presente investigación como placebo). Resultados: Al cabo de 8 semanas, solo CTM incrementó la fuerza máxima (p < 0.035) y redujo el grosor del pliegue subcutáneo de la pierna derecha (p < 0.03). Conclusiones: La técnica de electroestimulación con corriente TENS Modificada es efectiva para el entre namiento muscular. © 2015 Consejería de Turismo y Deporte de la Junta de Andalucía.

    (Universidad Nacional de Colombia, 2017) Delgado-Floody, P.; Caamaño-Navarrete, F.; Jerez-Mayorga, D.; Cofré-Lizama, A.; Osorio-Poblete, A.; Campos-Jara, C.; Guzmán-Guzmán, I.; Martínez-Salazar, C.; Carcamo-Oyarzun, J.
    Introduction: Childhood obesity is a serious public health issue, since it generates adverse results for physical and mental health. Objective: To correlate nutritional status and levels of self-esteem and physical performance in schoolchildren aged between 8 and 10. Materials and methods: 236 students participated, 117 male and 119 female, aged between 8 and 10, from two public schools in the municipality of Temuco. Weight, height, body mass index, mass/ fat percentage, waist contour, physical condition, hours of physical exercise per week and self-esteem were evaluated. Results: Overnutrition was documented in 43.6% of the students; children classified as obese (19%) presented higher levels of fat mass and waist contour (p<0.001), and also had a lower physical performance (p<0.05). The hours of physical exercise per week and the level of self-esteem were lower in obese school children, although this figure was not significant (p≥0.05). Conclusions: Obesity in school-aged children reveals alterations associated with physical performance, fat mass and negative trends on self-esteem. Despite developing at an early stage, the consequences associated with this condition can already be seen.

    Pharmacological treatment for challenging behavior in adults with intellectual disability: Systematic review and meta-analysis
    (Sociedad Española de Psiquiatría and Sociedad Española de Psiquiatría Biológica, 2023-01) Campos-Jara, R.; Martínez-Salazar, C.; Campos-Jara, Ch.; Fernándezx, J.; Martínez-García, D.; Contreras-Osorio, F.
    Introduction Few evidence on the use of antipsychotics in people with intellectual disabilities and challenging behaviors, generates the need to develop studies that contribute to collect, compare and synthesize the available information. The present systematic review and meta-analysis aims to determine the clinical efficacy of antipsychotic medication in reducing critical episodes in this population. Methods We searched Web of Science, Scopus, EBSCO, Embase, and PubMed for randomized controlled trials of antipsychotic medication versus placebo. Preliminarily yielded 1354 abstracts and citations; six studies with 274 subjects met the inclusion criteria of studies with experimental design, longitudinal type, with pre- and post-intervention measurements. Results There is evidence for the use of psychotropic drugs in the acute management of challenging behaviors in patients with intellectual disability (SMD = −0.85; 95% CI = −1.69 to −0.01; p = 0.05). Conclusions Our results coincide with the recommendations on the efficacy of the use of antipsychotics. Although our study provides evidence, the limited number of studies included in this research does not allow us to obtain totally conclusive results, although it can be considered as a guide for future studies.
