El presente artículo analiza la evidencia empírica que aportan los estudios sobre la influencia de los factores dinámicos asociados a la reincidencia criminal de menores infractores dentro del contexto español y portugués. La búsqueda de los términos Juvenile delinquency* OR juvenile offenders* AND recidivism* OR Risk factors * se realizó en las bases de datos Scopus, ScienceDirect, Web of science, Dialnet, Scielo y ProQuest. Aplicados los criterios de inclusión y exclusión, de un total de 105 653 artículos, se seleccionaron 20 para análisis cualitativo y 3 para incluir en el metaanálisis. El estudio permite concluir que los factores dinámicos con mayor capacidad de predicción son la educación, la relación con el grupo de pares, el tiempo de ocio, la familia y el consumo de SPA.

This article analyses the empirical evidence provided by studies on the influence of dynamic factors associated with the criminal recidivism of juvenile offenders in the Spanish and Portuguese context. The search for the terms Juvenile delinquency* OR juvenile offenders* AND recidivism* OR Risk factors* was carried out in the databases Scopus, ScienceDirect, Web of science, Dialnet, Scielo and ProQuest. After applying the inclusion and exclusion criteria, out of a total of 105 653 articles, 20 were selected for qualitative analysis and 3 for inclusion in the meta-analysis. The study allows us to conclude that the dynamic factors with the greatest predictive capacity are education, relationship with peer group, leisure time, family and PAS consumption.

Ticarcillin and piperacillin adsorption on to polyethersulfone haemodiafilter membranes in an ex-vivo circuit.

OBJECTIVES: To describe the adsorption of ticarcillin and piperacillin on to polyethersulfone (PES) membranes using the recirculation function on an ex-vivo renal replacement circuit. METHODS: Low (4-8 mg) or high (35-45 mg) doses of ticarcillin and low (4-8 mg) or high (70-80 mg) doses of piperacillin were added to 1 L of human blood-crystalloid mixture and circulated around an ex-vivo modified continuous renal replacement therapy machine at three different blood flow settings (150, 300 and 450 mL/min). Plasma samples were collected from the pre-filter port of the haemodiafilter circuit at consecutive timepoints for a total duration of 4 h. Plasma samples were measured using a validated ultra high performance liquid chromatography-tandem mass spectrometry method. RESULTS: Eighty-one samples including both drugs were collected from 18 experimental runs. Overall, the percentage of piperacillin adsorption for the low and high doses ranged from 21.3% to 27.1% and from 11.5% to 23%, and the percentage of ticarcillin adsorption for the low and high doses ranged from 4.2% to 14.3% and from 3.7% to 15.1%, respectively. The low dose of piperacillin consistently yielded more than 20% adsorption of dose for all blood flow rates. This decreased with high blood flow rates when the high dose of piperacillin was used. Ticarcillin generally displayed ≤5% adsorption, with the exceptions being the high dose at 150 mL/min and the low dose at 300 mL/min, which displayed ~15% adsorption. CONCLUSIONS: Adsorption of both drugs tended to be higher at the lowest blood flow rates and lowest doses. This is likely due to saturation of parts of the filter that have a chemical attraction to both piperacillin and ticarcillin. At low doses at all three blood flow rates, piperacillin demonstrated >20% adsorption, whereas ticarcillin tended to have low rates (up to ~≤15%) of adsorption on to PES membrane filters.

Diseño del cuestionario de creencias referidas al consumo de alcohol para jóvenes universitarios / Design of the alcohol consumption beliefs questionnaire for college students

El objetivo del presente estudio fue diseñar y validar el Cuestionario de creencias referidas al consumo de alcohol para jóvenes universitarios. La prueba se aplicó a una muestra de 240 jóvenes universitarios entre los 16 y los 25 años, en la ciudad de Bogotá. El diseño del Cuestionario se basó en el Modelo de Creencias e incluyó los componentes del mismo: percepción de riesgo/vulnerabilidad/severidad, barreras percibidas, beneficios percibidos, normas subjetivas y claves para la acción. Los resultados muestran que la prueba tiene un buen nivel de validez y confiabilidad. Se presenta una descripción general de los resultados obtenidos con la muestra final de jóvenes. Finalmente, se discute sobre las aplicaciones y alcances del Cuestionario, y la necesidad de ampliar la muestra con jóvenes de otras ciudades.

The purpose of present study was to design and validate of Alcohol Beliefs Questionnaire in adolescents universitaries; this instrument was applicated to the nonrandom sample was conformed by 240 young's between the 16 and the 25 years university students at Bogota city. The design of Questionnaire is based on the Health Belief Model and include theirs components: perceived risk and vulnerability, subjective norms, perceived barriers, perceived benefits and cues action. The results showed that the instrument has a good reliability and validity. Present description the results with sample include. Finally it is discussed the study limitations, for instance, althougth, it is recommended further applications of the instrument with other groups.
