BACKGROUND Total hip replacement (THR) is one of the most common orthopaedic procedures in the United Kingdom (UK). Historically, people following THR have been provided with hip precautions and equipment such as: raised toilet seats and furniture rises, in order to reduce the risks of dislocation post-operation.

RATIONALE Recent studies have shown that the incidence of bloodstream infections (BSIs) associated with arterial catheters (ACs) is comparable to that of central venous catheters (CVCs). In 2011, the CDC published guidelines recommending the use of limited barrier precautions during AC insertion. The goal of this study was to assess the attitudes and current antiseptic techniques employed by ph...

BACKGROUND Intensive care units (ICUs) are high-risk settings for the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE). METHODS In a cluster-randomized trial, we evaluated the effect of surveillance for MRSA and VRE colonization and of the expanded use of barrier precautions (intervention) as compared with existing practice (contro...

The investigation and discussion of metalinguistic ability requires a firm theoretical foundation if it is to contribute to a proper account of its role in L1 and L2 performance. A framework for elaborating more rigorous accounts of this and other major issues of language acquisition and performance will be presented here as a prerequisite to discussing the role of metalinguistic knowledge. In ...

Universal Grammar (UG) is a suspect concept. There is little agreement on what exactly is in it; and the empirical evidence for it is very weak. This paper critically examines a variety of arguments that have been put forward as evidence for UG, focussing on the three most powerful ones: universality (all human languages share a number of properties), convergence (all language learners converge...
