Programa nacional de mejora y conservación de los recursos genéticos de la encina y el alcornoque frente a la seca

Como respuesta a la gravedad de los procesos de decaimiento y mortalidad de la encina y el alcornoque, que amenazan la sostenibilidad de sus masas en la Península Ibérica, en el año 2019 se constituyó el subgrupo de trabajo “Mejora genética y fisiológica”, que forma parte del grupo de trabajo “Seca”, coordinado por el MITECO. Este subgrupo incluye a científicos y técnicos de varias administraciones y numerosos centros de investigación y Universidades y una empresa pública, expertos en mejora genética, fitopatología, ecología, propagación vegetativa, bioquímica y biología molecular. El programa tiene como objetivo la selección de genotipos de Quercus ilex y Q. suber tolerantes al estrés hídrico y a la podredumbre radical provocada por Phytophthora cinnamomi. A partir del estudio de 18 poblaciones y de 194 árboles “escape” seleccionados en focos de seca, se espera seleccionar un material apto para restaurar zonas afectadas por problemas de decaimiento. Se presenta una síntesis de las primeras actividades de caracterización e identificación de árboles escape en focos de seca, ensayos de invernadero para el estudio de la variabilidad poblacional en cuanto a vigor y tolerancia al estrés, recogida de muestras vegetales y edáficas para el análisis genético, molecular y de microbioma, identificación de marcadores moleculares asociados a resiliencia y micropropagación del material de mayor valor potencial

30-day morbidity and mortality of sleeve gastrectomy, Roux-en-Y gastric bypass and one anastomosis gastric bypass: a propensity score-matched analysis of the GENEVA data

Background: There is a paucity of data comparing 30-day morbidity and mortality of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB). This study aimed to compare the 30-day safety of SG, RYGB, and OAGB in propensity score-matched cohorts. Materials and methods: This analysis utilised data collected from the GENEVA study which was a multicentre observational cohort study of bariatric and metabolic surgery (BMS) in 185 centres across 42 countries between 01/05/2022 and 31/10/2020 during the Coronavirus Disease-2019 (COVID-19) pandemic. 30-day complications were categorised according to the Clavien–Dindo classification. Patients receiving SG, RYGB, or OAGB were propensity-matched according to baseline characteristics and 30-day complications were compared between groups. Results: In total, 6770 patients (SG 3983; OAGB 702; RYGB 2085) were included in this analysis. Prior to matching, RYGB was associated with highest 30-day complication rate (SG 5.8%; OAGB 7.5%; RYGB 8.0% (p = 0.006)). On multivariate regression modelling, Insulin-dependent type 2 diabetes mellitus and hypercholesterolaemia were associated with increased 30-day complications. Being a non-smoker was associated with reduced complication rates. When compared to SG as a reference category, RYGB, but not OAGB, was associated with an increased rate of 30-day complications. A total of 702 pairs of SG and OAGB were propensity score-matched. The complication rate in the SG group was 7.3% (n = 51) as compared to 7.5% (n = 53) in the OAGB group (p = 0.68). Similarly, 2085 pairs of SG and RYGB were propensity score-matched. The complication rate in the SG group was 6.1% (n = 127) as compared to 7.9% (n = 166) in the RYGB group (p = 0.09). And, 702 pairs of OAGB and RYGB were matched. The complication rate in both groups was the same at 7.5 % (n = 53; p = 0.07). Conclusions: This global study found no significant difference in the 30-day morbidity and mortality of SG, RYGB, and OAGB in propensity score-matched cohorts. © 2021, The Author(s)
