Verbatim and gist recall of sentences by dyslexic and non-dyslexic adults.

Forty-eight college students, 24 of them dyslexic, were presented with four sentences of increasing complexity. Participants were asked to repeat each sentence and a record was kept of the number of repetitions required before 100% correct accuracy was achieved. None of the 24 control participants required a total of more than eight repetitions over the four sentences, whereas among the dyslexics the total number of repetitions needed ranged from one to 25. Dyslexic participants were unpredictable in their performance from one level of difficulty to the next and inter-individual variability was far greater in the dyslexic group than in the control group. Overall, despite their relatively poor performance in achieving verbatim accuracy relative to non-dyslexic participants, dyslexic individuals regularly managed to preserve the gist of the sentences. Some theoretical issues arising from these results are discussed.

Effect of a novel integrated power toothbrush and toothpaste oral hygiene system on gingivitis.

The purpose of this article is to compare the gingivitis reduction efficacy relative to baseline of an integrated power toothbrush/toothpaste dispensing system prototype, the IntelliClean System from Sonicare and Crest. This was a randomized, controlled, parallel-group, examiner-blind study that examined the gingivitis reduction efficacy of a novel integrated system compared to a positive control consisting of manual toothbrushing coupled with daily flossing over a 4-week period. Mean change from baseline for gingival index (GI) and bleeding scores were tested using paired t tests for each treatment group, separately. Between-group comparisons were made with respect to change from baseline using analysis of covariance. Baseline values were used as the covariate. All tests were 2-sided with a 0.05 level of significance. A total of 66 subjects (61 women and 5 men) completed the study. The subjects ranged in age from 20 to 64 years with an overall mean age of 39.4 years. Baseline GI and bleeding scores were not statistically significantly different (P > .2) between the experimental integrated system group and the positive-control group. Both treatment regimen groups demonstrated highly statistically significant reductions in GI and bleeding scores vs baseline (P < .0001) at weeks 2 and 4. After 4 weeks, there was a 28% mean reduction in GI for the experimental group and a 23% mean reduction for the positive-control group. Similarly, there was a 28% mean reduction in bleeding for the experimental integrated system group and a 23% reduction for the positive-control group. However, no statistically significant treatment difference was found between the 2 groups (P > .5) for either measure at week 2 or week 4. This study demonstrated the efficacy of the IntelliClean System from Sonicare and Crest in significantly reducing gingivitis and bleeding relative to baseline after 4 weeks of use according to the manufacturer's instructions.

Multi-agency training for quality: reflections and recommendations.

Clinical governance within the National Health Service (NHS) and best value across local authorities in England have emphasised the need for decisions and actions being demonstrably evidence based. In an attempt to progress these related initiatives and facilitate a closer working relationship between NHS Trusts and local government departments, a multi-agency and interprofessional training event on evidence-based practice (EBP) was organised across three boroughs within Tyne and Wear. While there are advantages to different agencies learning and working in partnership to develop quality systems for health improvement, the reality of introducing EBP concepts and creating an evaluative culture within and across public sector organisations represents a major challenge. This article has adopted a case study approach to describe the key lessons learnt through critically reflecting on the planning and delivery of this training event, and it is hoped that it will be of value to other attempting similar projects in the future.
