ABSTRACT
Objective To analyze the cost-benefit ratio of primary trigeminal neuralgia patients with bad drug control and never accepted the surgical treatment through surgery [including microvascular decompression (MVD) ,percutaneous radiofrequency rhizotomy (RFR) ,stereotactic radiotherapy (SRS)] .Methods A total of 89 patients with primary trigeminal neuralgia who under-went surgical treatment for the first time from 2005 to 2013 were enrolled in this study ,including 27 patients with MVD ,23 patients with RFR and 39 patients with SRS .Evaluation criteria (effect factors) include facial pain (excellent :no pain and no drug treat-ment ;good :no pain but medication ;worse:less than 50% of patients with pain ;worse:more than 50% of patients with facial pain or need to undergo secondary surgery ) ,numbness ,cost and .Results The mean age of the patients treated with MVD was (50 .4 ± 14 .3)years old ,RFR was(73 .2 ± 13 .6) years old SRS was (72 .6 ± 11 .8) years old ,MVD group was younger than RFR and SRS group(P<0 .05);The average total cost of each surgical approach as follows :MVD was 50274 yuan ,RFR was 4539 yuan ,SRS was 38512 yuan (P<0 .05);The postoperative facial numbness proportion of MVD was 1 .1% ,RFR was 52 .2% and SRS was 28 .2% (P<0 .05);The ratio of patients who needed recurrent surgery in two years was MVD 26 .0% ,RFR 73 .9% and SRS 30 .7% (P<0 .05);The mean remission rate of MVD was 1 .6 years ,the RFR was 2 .1 years ,and the SRS was 1 .0 year(P<0 .05);The cost-benefit ratio of MVD was 31618 yuan ,RFR was 1982 yuan ,SRS was 39297 yuan(P<0 .05) .Conclusion The cost-ben-efit ratio of the three surgical from low to high were RFR ,MVD ,SRS ,which means the unit cost of RFR gain the highest ,followed by M VD and SRS .
ABSTRACT
This work aims to assess the economic impact of supplementation with arborea and agro-industrial by-products in zebu cattle. Productive performance test was conducted for 60 days in the municipality of Gómez Plata (Antioquia-Colombia). Twenty castrated males commercial zebu received five diets consisting for Pangola (Digitaria decumbens) (60%) and supplement (40%) containing matarratón (Gliricidia sepium) (MAT), coffee pulp (Coffea arabica) (CP), grape pomace (Vitis vinifera) (GP) or cottonseed (Gossypium sp.) (CS); the control diet (CON) was not formulated with these materials. The economic analysis included the cost-structure of diet, calculation of total and unit production cost, sensitivity analysis and cost-benefit ratio (B/C). In relation to CON diet, the cost per kilogram of diet was superior to CP and GP, 2.39 and 1.87 times, respectively. The value of a kilogram of meat for CP, GP and MAT diets was 3.47, 2.04 and 1.40 times higher compared with CON diet. The B/C ratio was negative for CP and GP diets, however, the sensitivity analysis showed that the introduction of GP is economically viable if its acquisition cost is lower. The costs associated with diet CS were slightly lower than the CON diet (93%), so the B/C ratio was slightly higher. It concludes that the introduction of arborea and by-products is not economically feasible in all cases because factors such as regional availability and dehydration increase production costs.
Este trabajo tiene por objetivo evaluar el impacto económico de la suplementación con recursos arbóreos y agroindustriales en ganado cebú. La prueba de desempeño productivo se realizó durante 60 días en el municipio de Gómez Plata (Antioquia-Colombia). Se emplearon 20 machos castrados cebú comercial, que recibieron cinco dietas constituidas por Pangola (Digitaria decumbens) (60%) y suplemento (40%) conteniendo matarratón (Gliricidia sepium) (MAT), pulpa de café (Coffea arabica) (PC), orujo de uva (Vitis vinifera) (OU) o semilla de algodón (Gossypium sp.) (SA); la dieta control (CON) no se formuló con estos materiales. El análisis económico incluyó elaboración de la estructura de costos por dieta, cálculo del costo total y unitario de producción, análisis de sensibilidad y relación beneficio-costo (B/C). En relación con la dieta CON, el costo por kilogramo de dieta fue superior para PC y OU, 2,39 y 1,87 veces, respectivamente. El valor del kilogramo de carne para las dietas PC, OU y MAT fue 3,47, 2,04 y 1,40 veces mayor respecto la dieta CON. La relación B/C para las dietas PC y OU fue negativa, no obstante, el análisis de sensibilidad mostró que la introducción de OU es económicamente viable si su costo de adquisición es menor. Los costos asociados con la dieta SA fueron ligeramente inferiores a la dieta CON (93%), por lo cual la relación B/C fue levemente superior. Se concluye que la introducción de subproductos no es económicamente viable en todos los casos, ya que factores como disponibilidad regional y procesos de deshidratación aumentan los costos de producción.
