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 PenĂnsula IbĂ©rica, en el año 2019
se constituyĂł el subgrupo de trabajo âMejora genĂ©tica y fisiolĂłgicaâ, que forma parte del grupo de
trabajo âSecaâ, coordinado por el MITECO. Este subgrupo incluye a cientĂficos y tĂ©cnicos de varias
administraciones y numerosos centros de investigaciĂłn y Universidades y una empresa pĂșblica,
expertos en mejora genĂ©tica, fitopatologĂa, ecologĂa, propagaciĂłn vegetativa, bioquĂmica y biologĂa
molecular. El programa tiene como objetivo la selecciĂłn de genotipos de Quercus ilex y Q. suber
tolerantes al estrĂ©s hĂdrico y a la podredumbre radical provocada por Phytophthora cinnamomi. A
partir del estudio de 18 poblaciones y de 194 ĂĄrboles âescapeâ seleccionados en focos de seca, se
espera seleccionar un material apto para restaurar zonas afectadas por problemas de decaimiento.
Se presenta una sĂntesis de las primeras actividades de caracterizaciĂłn e identificaciĂłn de ĂĄrboles
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 edåficas para el anålisis
genético, molecular y de microbioma, identificación de marcadores moleculares asociados a
resiliencia y micropropagaciĂłn 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 ClavienâDindo 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)
