BACKGROUND Revisional surgery is an important component of addressing weight regain and complications following primary bariatric surgery. Owing to provincial need and the complexity of this patient population, a specialized multidisciplinary revision clinic was developed. We sought to characterize patients who undergo revision surgery and compare their outcomes with primary bariatric surgery c...

BACKGROUND Hip and knee arthroplasties are common and successful procedures, however, success and durability are not guaranteed. The revision burden, defined as the ratio of implant revisions to the total number of arthroplasties in a specific period, is a measure of the steady state of arthroplasty success in a given registry. This study examines the hypothesis that revision burden would be si...

We address the problem of belief revision of logic programs, i.e., how to incorporate to a logic program P a new logic program Q. Based on the structure of SE interpretations, Delgrande et al. (2008; 2013b) adapted the well-known AGM framework (1985) to logic program (LP) revision. They identified the rational behavior of LP revision and introduced some specific operators. In this paper, a cons...

BACKGROUND Considering that revision rhinoplasty is one of the most difficult plastic surgical procedures, evaluating patient satisfaction is fundamental in order to determine success and identify variables that may affect the outcomes. Our first study objective was to determine satisfaction levels in revision patients and to compare results with those obtained in primary rhinoplasty patients. ...

We propose a formalism for specifying revisions in knowledge bases and belief sets. This formalism extends logic programming with stable model semantics. Main objects of our system are revision programs consisting of revision rules. A revision rule expresses a speciication of change or a constraint on a knowledge base. There are two types of revision rules. In-rules require that an element be i...

BACKGROUND Increasing utilization of primary total knee arthroplasty (TKA) is projected to expand demand for revision TKA. Revision TKAs are procedurally complex and incur high costs on our financially constrained healthcare system. The purpose of this study was to use a case-control design to identify factors predisposing to revision TKA, particularly demographic, clinical and perioperative te...

PURPOSE Kasai portoenterostomy is the standard therapy for biliary atresia (BA). If Kasai is unsuccessful, there is controversy over whether revision of Kasai restores adequate biliary drainage. Although there are several reports of laparoscopic Kasai (Lap-Kasai), none has described laparoscopic revision (Lap-revision). The purposes of this study were to evaluate the feasibility and efficacy of...

This position paper discusses the difficulty of interpreting iterated belief revision in the scope of the existing literature. Axioms of iterated belief revision are often presented as extensions of the AGM axioms, upon receiving a sequence of inputs. More recent inputs are assumed to have priority over less recent ones. We argue that this view of iterated revision is at odds with the claim, ma...
