ABSTRACT
Introducción: La obesidad y las enfermedades asociadas a ella suponen un importante problema, y no solo sanitario, sino también económico, ya que muchas de esas patologías son subsidiarias de tratamiento farmacológico de por vida. La cirugía bariátrica y metabólica, a priori, disminuye la demanda de medicamentos de estos pacientes, pero puede condicionar otro tipo de necesidades farmacológicas. El objetivo del estudio es demostrar si existe un descenso real del gasto farmacológico tras la cirugía bariátrica. Material y métodos: Análisis retrospectivo transversal de los pacientes intervenidos en nuestro centro entre 2012 y 2016, comparando las distintas comorbilidades y los gastos farmacológicos asociados a ellas un mes antes y a los 2años de la cirugía. Resultados: Fueron intervenidos 400 pacientes. Se presentaron los resultados mostrando para cada una de las técnicas quirúrgicas estudiadas las diferencias entre la resolución de las distintas comorbilidades y el ahorro farmacológico generado. La comorbilidad más coste-efectiva del estudio fue la diabetes mellitus tipo2 (DM2). La técnica quirúrgica con mejores resultados fue el bypass metabólico, presentando una diferencia de costes tras la cirugía de 507euros mensuales (p<0,001). Conclusiones: En un seguimiento de 2años tras la cirugía bariátrica se produce un descenso en la prevalencia de las enfermedades asociadas a la obesidad y del gasto farmacológico asociado a ellas, lo que demuestra que este tipo de intervención resulta eficiente a medio plazo.

Introduction: Obesity and associated diseases represent an important health and economic problem since pharmacological treatment for many of these pathologies needs lifelong subsidies. Theoretically, bariatric and metabolic surgery decreases the medication requirements of patients for these diseases but may result in other types of pharmacological needs. This study aims to demonstrate whether there is a real decrease in pharmacological expenditure after bariatric surgery. Material and methods: Retrospective cross-sectional analysis of patients who were treated in our centre between 2012 and 2016, comparing different associated comorbidities and pharmacological expenses one month before and 2years after surgery. Results: 400 patients were operated. The results were presented, showing the differences between the resolution of the different comorbidities and the pharmacological savings generated for each of the surgical techniques studied. The most cost-effective comorbidity in the study was type2 diabetes mellitus (DM2). The surgical technique with the best results was metabolic bypass, presenting a cost difference after surgery of 507euros per month (P<.001). Conclusions: In a 2-year follow-up after bariatric surgery, a decreased prevalence of obesity-related diseases and associated pharmacological expenditure was observed, showing the efficiency of this intervention over the medium term.

ABSTRACT
A highly sensitive and specific SPR-based competitive immunoassay for the detection of Thiabendazole (TBZ) has been developed. An indirect format where a TBZ-protein conjugate is immobilized onto gold surfaces has been selected. Under the optimal conditions, a LOD of 0.67 nM (0.13 µg L(-1)) and an IC(50) of 3.2 nM (0.64 µg L(-1)) have been achieved which are comparable to the values obtained by conventional ELISA. Analysis of real samples has been attempted by first evaluating the influence of complex matrix samples coming from whole oranges and secondly measuring samples containing TBZ previously evaluated by chromatographic methods. A methanolic extraction procedure followed by a simple dilution in assay buffer has proven to be sufficient to measure orange samples using the developed immunoassay with an excellent recovery percentage. The sensitivity and the feasibility of measuring whole orange samples demonstrate the effectiveness and robustness of the SPR biosensor, which can be useful for the determination of TBZ in food at concentrations below the Maximum Residue Levels (MRLs) established by the European legislation.
