    Background: Surgical mortality data are collected routinely in high-income countries, yet virtually no low- or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI). Methods: This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression. Results: Data were obtained for 10 745 patients from 357 centres in 58 countries; 6538 were from high-, 2889 from middle- and 1318 from low-HDI settings. The overall mortality rate was 1⋅6 per cent at 24 h (high 1⋅1 per cent, middle 1⋅9 per cent, low 3⋅4 per cent; P < 0⋅001), increasing to 5⋅4 per cent by 30 days (high 4⋅5 per cent, middle 6⋅0 per cent, low 8⋅6 per cent; P < 0⋅001). Of the 578 patients who died, 404 (69⋅9 per cent) did so between 24 h and 30 days following surgery (high 74⋅2 per cent, middle 68⋅8 per cent, low 60⋅5 per cent). After adjustment, 30-day mortality remained higher in middle-income (odds ratio (OR) 2⋅78, 95 per cent c.i. 1⋅84 to 4⋅20) and low-income (OR 2⋅97, 1⋅84 to 4⋅81) countries. Surgical safety checklist use was less frequent in low- and middle-income countries, but when used was associated with reduced mortality at 30 days. Conclusion: Mortality is three times higher in low- compared with high-HDI countries even when adjusted for prognostic factors. Patient safety factors may have an important role.

    Con el objetivo de evaluar la eficiencia de la sincronización de celos y ovulaciones en vaquillonas para carne y leche en condiciones de pastoreo extensivo en la región San Martín área del Bajo Mayo, se realizó un ensayo con cinco tratamientos en cuatro predios y en nueve meses consecutivos. Se utilizaron solamente vaquillonas con actividad cíclica, con condición corporal igual o mayor a 3.5 (escala de 1 a 5). Los tratamientos fueron: para el tratamiento uno (1) se empleó en el día cero el CIDR + 0,8 ml., de benzoato de estradiol, al día 7 se aplicó PgF2alfa a la dosis de 5ml. Luego en el día 8 se aplicó 0,4 ml de Benzoato de estradiol, 30 horas después se realizó la IATF. Para el tratamiento dos (2) se empleó 5 ml., de la hormona GnRH, como acetato de Buseralina en el día cero, en el día 7 se aplicó 5 ml de PgF2 alfa, en el día 9 se aplicó 2,5 ml de GNRH, 24 horas después se realizó la IATF. Para el tratamiento 3, se empleó el Crestar como implante hormonal en el dorso de la oreja de los vacunos en el día cero, se removió el día 7 para luego aplicar 5 ml de PgF2alfa, el día 8 se aplicó 0,4 ml de Benzoato de estradiol, 30 horas después se realizó la IATF. Para el tratamiento 4 se empleó la Prostaglandina F2 alfa, en dosis única de 5 ml, previa evaluación de la presencia de un cuerpo lúteo al examen transrectal en los animales experimentales. Todos los animales estuvieron sometidos al pastoreo, grupo control y grupos tratamientos. Los bovinos experimentales estuvieron sometidos al control diagnóstico de ciclicidad ovárica libre de patologías reproductivas. Los estudios del presente trabajo se realizaron en fundos e institutos: (1) Risso el centro poblado de Yacucatina, (2) Manosalva – Centro Poblado Troncal del distrito de Cuñumbuque, (3) Instituto Nacional de Investigación Agraria (INIA) - Estación Experimental el Porvenir del distrito de Juan Guerra; durante los meses de mayo a diciembre del año 2014.Los resultados se sometieron a cálculos estadísticos empleando el análisis de variancia para determinar si hay diferencia significativa entre los tratamientos. No hubo diferencias significativas en los porcentajes de preñez (PP) entre los protocolos estudiados prueba de Duncan Alfa: = 0.05 donde (p> 0.05). Los cinco protocolos fueron eficientes pero los protocolos con IATF resultaron ser más eficaces al lograr un mayor porcentaje de preñez. Si bien existieron diferencias entre predios, el efecto meses fue más importante debido a diferencias en clima, lluvia y consecuentemente oferta forrajera.With the objective of evaluating the efficiency of the synchronization of estrus and ovulations in heifers for meat and milk under extensive grazing conditions in the San Martín region of the Bajo Mayo area, a trial was conducted with five treatments in four farms and in nine consecutive months. Only heifers with cyclic activity were used, with body condition equal to or greater than 3.5 (scale of 1 to 5). The treatments were: for the treatment one (1) was used on day zero the CIDR + 0.8 ml of estradiol benzoate, on day 7 PgF2alpha was applied at the dose of 5 ml. Then, on day 8, 0.4 ml of estradiol benzoate was applied, 30 hours later the IATF was performed. For treatment two (2), 5 ml of the hormone GnRH was used as Buseralina acetate on day zero, on day 7 5 ml of PgF2 alpha was applied, on day 9 2.5 ml of GNRH, 24 hours after the IATF was carried out. For treatment 3, the Crestar was used as a hormonal implant on the back of the cattle's ear on day zero, it was removed on day 7 to then apply 5 ml of PgF2alpha, on day 8 0.4 ml of Benzoate was applied of estradiol, 30 hours later the IATF was performed. For treatment 4, Prostaglandin F2 alpha was used in a single dose of 5 ml, after evaluation of the presence of a corpus luteum at transrectal examination in the experimental animals. All the animals were subjected to grazing, control group and treatment groups. The experimental bovines were subjected to the diagnostic control of ovarian cyclicity free of reproductive pathologies. The studies of the present work were carried out in farms and institutes: (1) Risso the Yacucatina town center, (2) Manosalva - Trunk Town Center of the Cuñumbuque district, (3) National Institute of Agrarian Research (INIA) - Experimental Station el Future of the district of Juan Guerra; during the months of May to December 2014. The results were subjected to statistical calculations using the analysis of variance to determine if there is a significant difference between the treatments. There were no significant differences in the pregnancy percentages (PP) between the Duncan Alpha test protocols studied: = 0.05 where (p> 0.05). The five protocols were efficient but the protocols with IATF proved to be more effective in achieving a higher percentage of pregnancy. Although there were differences between farms, the months effect was more important due to differences in climate, rainfall and consequently fodder supply.Trabajo de investigaciónAp
