Double it up: Vocabulary size comparisons between UK bilingual and monolingual toddlers.

We compared vocabulary sizes in comprehension and production between bilingual toddlers growing up in the United Kingdom (UK) and age-matched UK English monolinguals (12-36 months old) using parent-report vocabulary questionnaires. We found that bilingual toddlers' vocabulary sizes in English were smaller than the vocabulary sizes of their monolingual peers. Notably, this vocabulary gap was not found when groups were compared on conceptual vocabulary in comprehension. Conceptual scoring also reduced the vocabulary gap in production but group differences were still significant. Bilingual toddlers knew more words than monolinguals when words across their two languages were added together, for both comprehension and production. This large total vocabulary size could be attributed to a high proportion of doublets (cross-linguistic word pairs with the same meaning) in bilinguals' vocabularies. These findings are discussed in relation to language exposure, facilitation from cross-linguistic overlap and maturation constraints on vocabulary size.

Facilitators and barriers to the implementation of surgical safety checklist: an integrative review.

Surgical procedures pose an immense risk to patients, which can lead to various complications and adverse events. In order to safeguard patients' safety, the World Health Organization initiated the implementation of the Surgical Safety Checklist (SSC) in operating theatres worldwide. The aim of this integrative review was to summarize and evaluate the use and implementation of SSC, focusing on facilitators and barriers at the individual, professional, and organizational levels. This review followed closely the integrative review method by Whittemore and Knafl. An English literature search was conducted across three electronic databases (PubMed, CINAHL, and EMBASE) and other hand search references. Keywords search included: 'acute care', 'surgical', 'adult patients', 'pre-operative', 'intra-operative', and 'post-operative'. A total of 816 articles were screened by two reviewers independently and all articles that met the pre-specified inclusion criteria were retained. Data extracted from the articles were categorized, compared, and further analysed. A total of 34 articles were included with the majority being observational studies in developed and European countries. Checklists had been adopted in various surgical specialities. Findings indicated that safety checklists improved team cohesion and communication, resulting in enhanced patient safety. This resulted in high compliance rates as healthcare workers expressed the benefits of SSC to facilitate safety within operating theatres. Barriers included manpower limitations, hierarchical culture, lack of staff involvement and training, staff resistance, and appropriateness of checklist. Common facilitators and barriers at individual, professional, and organizational levels have been identified. Staff training and education, conducive workplace culture, timely audits, and appropriate checklist adaptations are crucial components for a successful implementation of the SSC. Methods have also been introduced to counter barriers of SSC.
