Pancreatogastrostomy versus pancreatojejunostomy for RECOnstruction after partial PANCreatoduodenectomy (RECOPANC): study protocol of a randomized controlled trial UTN U1111-1117-9588

BACKGROUND: Pancreatoduodenectomy is one of the most complex abdominal operations, usually performed for tumors of the periampullary region and chronic pancreatitis. Leakage of pancreatic juice from the pancreatoenteric anastomosis, called postoperative pancreatic fistula, is the most prominent postoperative complication. Retrospective studies show a significant reduction of fistula rates with pancreatogastrostomy as compared to pancreatojejunostomy, the most frequently employed method of pancreatoenterostomy. Most single-center prospective trials, however, have not validated this finding. A large multicenter trial is needed for clarification. METHODS/DESIGN: RECOPANC is a prospective, randomized, controlled multicenter trial with two treatment arms, pancreatogastrostomy versus pancreatojejunostomy. The trial hypothesis is that postoperative pancreatic fistula rate is lower after pancreatogastrostomy when compared to pancreatojejunostomy. Fourteen academic centers for pancreatic surgery will participate to allocate 360 patients to the trial. The duration of the entire trial is four years including prearrangement and analyses. DISCUSSION: Postoperative pancreatic fistula is the main reason for clinically important postoperative morbidity after pancreatoduodenectomy. The primary goal of the chosen reconstruction technique for pancreatoenteric anastomosis is to minimize postoperative fistula rate. A randomized trial performed at multiple high-volume centers for pancreatic surgery is the best opportunity to investigate one of the most crucial issues in pancreatic surgery.

Relational aggression in adolescents with conduct disorder:sex differences and behavioral correlates

As most research on conduct disorder (CD) has been conducted on male participants, it has been suggested that female-specific symptoms may be underestimated based on current DSM-5 criteria. In particular, relational aggression, i.e. the hurtful, often indirect, manipulation of relationships with the intention of damaging the other’s social position, has been proposed as a characteristic of CD that is more common in females. In addition, sex-specific studies on correlates of relational aggressive behavior are lacking. Relational aggression may be strongly related to the correlates of proactive aggression, namely low affective empathy, and high levels of callous-unemotional (CU) traits and relational victimization. Thus, the present study investigated sex differences in relational aggression, and associations between relational aggression and correlates of proactive aggression in 662 adolescents with CD (403 females) and 849 typically-developing controls (568 females) aged 9–18 years (M = 14.74, SD = 2.34) from the European multi-site FemNAT-CD study. Females with CD showed significantly higher levels of relational aggression compared to males with CD, whereas no sex differences were seen in controls. Relational aggression was only partly related to correlates of proactive aggression in CD: Independent of sex, CU traits showed a positive association with relational aggression. In females only, cognitive, but not affective empathy, was negatively associated with relational aggression. Relational victimization was more strongly associated with relational aggression in males compared to females. Despite interesting sex specific correlates of relational aggression, effects are small and the potential clinical implications should be investigated in future studies

Elaboración de Instrumentos de Evaluación Diagnóstica para 3° y 4° Básico en el dominio de las habilidades lectoras.

Este trabajo consiste en la elaboración e implementación de un material pedagógico , que permita medir las conductas de entrada de los estudiantes en marzo 2020, en la asignatura de Lenguaje y Comunicación, específicamente en el Eje de Comprensión lectora , de este modo tener datos que le permitan a la Escuela Escuela José Alejandro Bernales de Conchalí , buscar medidas oportunas en el quehacer pedagógico que realizan los docentes y que a la vez vayan en pos de los aprendizajes de los estudiantes, en lo que respecta al desarrollo de las habilidades lectoras. Cabe señalar que nuestra escuela, hace dos años se encuentra en la categoría de desempeño “Insuficiente”, de no salir de este nivel, dentro de cinco años, la posibilidad de cerrar la escuela es inminente. Por lo mencionado anteriormente este trabajo de grado II, se centró en la necesidad de crear una Prueba Diagnóstica , para los estudiantes de 3° y 4° Básico de la Escuela. Esta prueba tiene 4 textos con un total de 20 preguntas cada una, de selección múltiple y preguntas abiertas de reflexión. Consta de una tabla de especificaciones que indica las habilidades lectoras que se están evaluando. Los resultados fueron tabulados para luego poder identificar que estudiantes se encuentran en nivel Insuficiente, Elemental, Adecuado y que habilidades lectora
