MH is a feasible and safe alternative to EH in selected patients with CLLTs. The proposed classification system may be useful in guiding the surgical treatment of CLLTs.

RALR and LLR display similar safety, feasibility, and effectiveness for hepatectomies, but further studies are needed before any final conclusion can be drawn, especially in terms of oncologic and cost-effectiveness outcomes.

Predicting customer purchase behavior is an interesting and challenging task. In the e-commerce context, meeting this challenge requires confronting many problems not observed in the traditional business context. Recommender system technology has been widely adopted by e-commerce websites. However, a traditional recommendation algorithm cannot perform well the predictive task in this context. This study intends to build a predictive framework for customer purchase behavior in the e-commerce context. This framework, known as CustOmer purchase pREdiction modeL (COREL), may be understood as a two-stage process. First, associations among products are investigated and exploited to predicate customer's motivations, i.e., to build a candidate product collection. Next, customer preferences for product features are learned and subsequently used to identify the candidate products most likely to be purchased. This study investigates three categories of product features and develops methods to detect customer preferences for each of these three categories. When a product purchased by a particular consumer is submitted to COREL, the program can return the top n products most likely to be purchased by that customer in the future. Experiments conducted on a real dataset show that customer preference for particular product features plays a key role in decision-making and that COREL greatly outperforms the baseline methods.

The oncologic outcomes of LADG for AGC patients were comparable with open approach. Although open distal gastrectomy may be associated with shorter operative time, patients undergoing laparoscopic approach may be benefitted from a shorter hospital stay and a faster resumption without translation into an increase in both postoperative morbidity and mortality. Nevertheless, further prospective, controlled studies, and extended follow-up are needed for a more comprehensive comparison between the 2 procedures.
