Il trattamento dei tumori stromali gastrici (GIST). Revisione della letteratura e descrizione di un caso
2005
background: Gastrointestinal stromal tumors (GIST) are rare mesenchimal tumors that are characterized by constitutive overexpression of the tyrosin-kinase receptor KIT (CD 117). The authors analyse the basis of the treatment of gastric GIS, starting form the study of a recent observed case. Experimental design: Report of one case treated with endoscopic resection. Evaluation of treatment and 2-years follow- results: The treatment of gastric GIS I must be modulated on prognostic, genetic and molecular factors. These factors are the basis of the formation and growth of GIST. conclusions: Complete surgical extirpation without rupture remains the only curative treatment of localized favourable …

Twenty-year trends in the prevalence of Down syndrome and other trisomies in Europe : impact of maternal age and prenatal screening
2013
This study examines trends and geographical differences in total and live birth prevalence of trisomies 21, 18 and 13 with regard to increasing maternal age and prenatal diagnosis in Europe. Twenty-one population-based EUROCAT registries covering 6.1 million births between 1990 and 2009 participated. Trisomy cases included live births, fetal deaths from 20 weeks gestational age and terminations of pregnancy for fetal anomaly. We present correction to 20 weeks gestational age (ie, correcting early terminations for the probability of fetal survival to 20 weeks) to allow for artefactual screening-related differences in total prevalence. Poisson regression was used. The proportion of births in …
Bidirectional labeling for solving vehicle routing and truck driver scheduling problems
2020
Abstract This paper studies the vehicle routing and truck driver scheduling problem where routes and schedules must comply with hours of service regulations for truck drivers. It presents a backward labeling method for generating feasible schedules and shows how the labels generated with the backward method can be combined with labels generated by a forward labeling method. The bidirectional labeling is embedded into a branch-and-price-and-cut approach and evaluated for hours of service regulations in the United States and the European Union. Computational experiments show that the resulting bidirectional branch-and-price-and-cut approach is significantly faster than unidirectional counterp…
