Introduction
Hemolysis can occur during sample collection, handling and transport. It is more frequent when the non-laboratory staff performs sampling. The aim of this study was to assess nurses’ knowledge on the causes of hemolysis and consequential impact on the laboratory tests results. Additionally, the differences in knowledge, related to work experience, professional degree and previous education about hemolysis were explored.Materials and methods
An anonymus survey, containing 11 questions on demographics, causes of hemolysis, its impact on biochemical parameters and nurses’ attitude towards additional education in preanalytics, was conducted in four Croatian hospitals. The answers were compared by Chi-squared and Fischer exact test.Results
In total, 562 survey results were collected. Majority of nurses declared familiarity with the term “hemolysis” (99.6%). There were 77% of correct answers regarding questions about the causes of hemolysis, but only 50% when it comes to questions about interference in biochemical tests. The percentage of correct answers about causes was significantly lower (P = 0.029) among more experienced nurses, and higher (P = 0.027) in those with higher professional degree, while influence of previous education was not significant. Also, higher percentage of correct answers about interferences was encountered in nurses with longer work experience (P = 0.039). More than 70% of nurses declared that additional education about preanalytical factors would be beneficial.Conclusion
Croatian nurses are familiar with the definition of hemolysis, but a lack of knowledge about causes and influence on laboratory test results is evident. Nurses are eager to improve their knowledge in this field of preanalytical phase.Key words: hemolysis, nurses, survey, preanalytical phase 相似文献3.

Radio Frequency Identification (RFID) systems identify and track objects, animals and, in principle, people. The ability to
gather information obtained by tracking consumer goods, government documents, monetary transactions and human beings raises
a number of interesting and important privacy issues. Moreover, RFID systems pose an ensemble of other ethical challenges
related to appropriate uses and users of such systems. This paper reviews a number of RFID applications with the intention
of identifying the technology’s benefits and possible misuses. We offer an overview and discussion of the most important ethical
issues concerning RFID, and describes and examine some methods of protecting privacy.
Norman G. Einspruch serves as a consultant to several high-technology companies, one of which is in the RFID components and
systems business. 相似文献

Test procedures and their accuracy in determining critical fall height (CFH) on sporting grounds are paramount to player safety.
The procedure currently adopted for synthetic turf in Australian football [1] consists of four consecutive drops at various drop heights at three test locations on the sample. The quantity and packing
of the infill in third-generation turf and the pooling effect of the rubber particles with consecutive drops suggests that
the current standard protocol may need re-assessment. Therefore, the purpose of this pilot study was to investigate whether
current methods of testing for CFH are appropriate for third-generation synthetic turf or whether an alternative or adapted
method needs to be developed. CFH was measured, using a HISUN Uniaxe-II Impact Tester, on 12 combinations of synthetic turf
samples (four different products with three shock pad options). Three conditions were investigated on each sample; the existing
protocol; an alternative 12 single-drop protocol and four single drops from the CFH determined from the existing protocol.
A significant difference was found for both absolute and percentage difference between the existing and 12 single-drop protocol,
with p = 0.001 and t = 4.33 and p < 0.001 and t = 6.03, respectively. There was also a significant difference between the CFH reached with and without a shock pad for both
the existing protocol and the 12 single-drop protocol. The results of this pilot study demonstrate that differences do occur
with alterations to the existing protocol and highlight the need for a more detailed characterisation of testing methods on
third-generation synthetic turf and the response of surfaces to them. 相似文献

This paper examines the role of trust in the information continuum. It argues that in the context of Canadian federal government records, an analogous ??trust continuum?? is a useful model for analysing the relationships that exist between creator, archives and user in the information-abundant environment. The paper borrows from sociological theory to posit that creator, archives and user are bound together in a complex expert system that facilitates trust and mitigates risk in a broad societal context and contends that these interactions are shaped at the macro level by a dominant public discourse of accountability. These points are illustrated through three recent examples at Library and Archives Canada. First, the relationship between Canadian society and the archives is explored by interrogating the concept of relevance and assessing the feasibility of managing a pan-Canadian collection via a national network of knowledge institutions. Then, the role of trust between the archives and the creator in the management of government digital information resources is examined in light of the recently issued Directive on Recordkeeping, and in the context of LAC??s Trusted Digital Repository. Finally, Commissions of Inquiry??and the Indian Specific Claims Commission in particular??demonstrate both the power of archival records in repairing trust between a society and its government and the iterative nature of the relationship between the user and the archives. 相似文献

Educational transitions are associated with significant changes. If students cannot overcome these challenges, their well‐being and motivation may be impaired. Students with clinically relevant emotional or behavioural disorders (EBDs) are at risk for negative transitional experiences. We conducted a systematic review summarising transitional outcomes of students with EBDs. After an electronic search in eight scientific databases, 4,930 publications were screened against six inclusion criteria. Two coders assessed the eligibility of 181 full‐texts. We included k = 22 studies published in English or German (1988–2017). Students with autism (k = 15) and transitions out of school (k = 13) were examined most frequently. Well‐being, achievements, social participation, support and expectations were observed. Poor well‐being and social difficulties were prevalent, but often adjusted over time. The results are limited by the inclusion criteria and search procedures. Nevertheless, the review closes a research gap and has implications for the implementation of interventions and a supportive transition environment for students with clinically relevant EBDs. Further research on individual changes and supportive approaches during transitions is needed. 相似文献
