Surgical resection for ampullary lesions lacks clear guidelines. Pancreaticoduodenectomy (PD) is the standard treatment for malignant ampullary tumors but is often excessive for ampullary adenomas (AAs) due to its high morbidity and mortality. Transduodenal ampullectomy (TDA) is generally reserved for small benign lesions where endoscopic treatment fails, but its role in early ampullary cancers is debatable.

Aim: To evaluate the transfer effects of a home-based computerized executive function intervention on non-targeted cognitive functions (visual perception and memory), quality of life (QoL), and participation in children with cerebral palsy (CP), and to determine whether any improvements were maintained 9 months after the intervention.

Method: Sixty children with CP (aged 8-12 years) were randomly allocated to the intervention (15 females/15 males, mean age 10 years 4 months [SD = 1 years 8 months], age range 8-12 years) or waitlist (control) (15 females/15 males, mean age 10 years [SD = 1 years 9 months], age range 8-12 years) group. The intervention group underwent a home-based executive function intervention programme for 30 minutes per day, 5 days a week, for 12 weeks.

Objectives: Neuroimaging studies of dyskinetic cerebral palsy (CP) are scarce and the neuropathological underpinnings are not fully understood. We delineated the corticospinal tract (CST) and cortico-striatal-thalamocortical (CSTC) pathways with probabilistic tractography to assess their (1) integrity and (2) association with motor functioning in people with dyskinetic CP.

Methods: Diffusion weighted magnetic resonance images were obtained for 33 individuals with dyskinetic CP and 33 controls.

Unlabelled: Children with Cerebral Palsy (CP) experience Social Cognition (SC) difficulties, which could be related to executive functioning. While motor interventions are common, there is limited knowledge about the impact of cognitive interventions on SC in this population. This study examined the relationship between SC and Executive Function (EF) skills and the effectiveness of an EF intervention that included some SC tasks for improving SC in children with CP.

The set-covering problem aims to find the smallest possible set of subsets that cover all the elements of a larger set. The difficulty of solving the set-covering problem increases as the number of elements and sets grows, making it a complex problem for which traditional integer programming solutions may become inefficient in real-life instances. Given this complexity, various metaheuristics have been successfully applied to solve the set-covering problem and related issues.
