This is a translation of the paper “Recommendations for the application and follow-up of quality controls in medical biology laboratories” published in French in the journal Annales de Biologie Clinique (Recommandations pour la mise en place et le suivi des contrôles de qualité dans les laboratoires de biologie médicale. Ann Biol Clin (Paris). 2019;77:577-97.). The recommendations proposed in this document are the result of work conducted jointly by the Network of Accredited Medical Laboratories (LABAC), the French Society of Medical Biology (SFBC) and the Federation of Associations for External Quality Assessment (FAEEQ). The different steps of the implementation of quality controls, based on a risk analysis, are described. The changes of reagent or internal quality control (IQC) materials batches, the action to be taken in case of non-conform IQC results, the choice of external quality assessment (EQA) scheme and interpretation of their results as well as the new issue of analyses performed on several automatic systems available in the same laboratory are discussed. Finally, the concept of measurement uncertainty, the robustness of the methods as well as the specificities of near-patient testing and rapid tests are described. These recommendations cannot apply for all cases we can find in medical laboratories. The implementation of an objective alternative strategy, supported with documented evidence, might be equally considered. 相似文献

Serum β2-microglubin (β2-m) levels were measured in oral carcinoma patients and compared with normal healthy controls. It was observed that there
was a significant rise in serum β2-microglobulin in oral carcinoma patients. Progressively higher values were obtained as the cancer advanced clinically. Therefore
the estimation of serum β2-microglobulin may be useful as one of a battery of tests in the assessment of oral carcinoma patients. 相似文献

This study investigated potential differences in inductive behavioural and verbal strategy-use between children (aged 6–8 years) from indigenous and non-indigenous backgrounds. This was effected by the use of an electronic device that could present a series of tasks, offer scaffolded assistance and record children’s responses. Children from non-indigenous ethnic backgrounds, starting at a lower level, profited as much from dynamic testing as did indigenous children but were unable to progress to the standard of this latter group. Irrespective of ethnic group, dynamic testing resulted in greater accuracy, fewer corrections, and reduced trial-and-error behaviour than repeated practice. Improvements in strategy-use were noted at both the group and individual level. After dynamic training, children from both ethnic groups showed a superior capacity for inductive reasoning although indigenous children subsequently used more inductive strategies. The study revealed individual differences between and within different ethnic groups and variability in the sorts of help required and subsequent strategy progression paths. 相似文献

The aim of the current study was to investigate to what extent children’s potential for learning is related to their level of cognitive flexibility. Potential for learning was measured through a dynamic testing procedure that aimed to measure how much a child can profit from a training procedure integrated into the testing process, including the amount and type of feedback the children required during this training procedure. The study followed a pre-test–training–post-test control group design. Participants were 153 6–7-year-old children. Half of this group of children were provided with a standardised graduated prompts procedure. The other half of the participants performed a non-inductive cognitive task. Children’s cognitive flexibility was measured through a card sorting test and a test of verbal fluency. Results show that cognitive flexibility was positively related to children’s performance, but only for children in the practice-only condition who received no training. These outcomes suggest that dynamic testing, and more in particular, the graduated prompting procedure, supports children’s cognitive flexibility, thereby giving children with weaker flexibility the opportunity to show more of their cognitive potential as measured through inductive reasoning.

Game consoles have been adopted as a learning platform in school education. However, there is a scarcity of studies examining the utility of games consoles with built‐in WiFi as affordable learning platforms in universities. This paper contributes to knowledge about the capacity of the Nintendo DSi to create new learning spaces mediated and supported by DSi consoles, free Flipnote Studio software for DS and a dedicated course website. An application of the DSi is described for remote supplemental language tutorial activities linking a dispersed body of students on a year‐abroad programme. It was found that the use of DSi as a mobile learning platform has great potential if it is used in combination with shared webspace, such as Hatena, by increasing students' learning motivation and eliminating fears/uncertainty about their progress. 相似文献

In this study, dynamic testing principles were applied to examine progression of analogy problem solving, the roles that cognitive flexibility and metacognition play in children's progression as well as training benefits, and instructional needs of 7‐ to 8‐year‐old gifted and average‐ability children. Utilizing a pretest training posttest control group design, participants were split in four subgroups: gifted dynamic testing (n = 22), gifted unguided practice (n = 23), average‐ability dynamic testing (n = 31), and average‐ability unguided practice (n = 37). Results revealed that dynamic testing led to more advanced progression than unguided practice, and that gifted and average‐ability children showed equivalent progression lines and instructional needs. For children in both ability categories, cognitive flexibility was not found to be related to progression in analogy problem solving or training benefits. In addition, metacognition was revealed to be associated with training benefits. Implications for educational practice were provided in the discussion. 相似文献
