Elimination of lipaemic interference by high-speed centrifugation

IntroductionIn order to deliver high quality results, detection and elimination of possible analytical interferences, such as lipaemia, is crucial. The aim of this study is to evaluate the efficacy of high-speed centrifugation in eliminating lipaemic interference and to define own lipaemic index (LI) for the studied biochemical analytes.Materials and methodsEvaluated analytes were: albumin, alkaline phosphatase, alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), calcium, creatinine, gamma-glutamyltransferase (GGT), glucose, phosphates, total proteins, urea and total bilirubin. Those analytes and LIs have been analysed in duplicate in the Roche Diagnostics-c8000 analyser in samples centrifuged at 3000 rpm/10 minutes in the SL16 (Thermo Scientific, Waltham, USA) centrifuge and according to an own high-speed centrifugation protocol (12,900 rpm/15 minutes) in the MicroCL17R (Thermo Scientific, Waltham, USA) centrifuge. Lipaemia has been measured in each sample. The efficiency of high-speed centrifugation is verified by the Wilcoxon test (P < 0.05). In cases where significant differences are observed, our own LI is calculated. For ALT and AST, it is verified by McNemar test (P < 0.05). For creatinine, both Wilcoxon and McNemar test were applied.ResultsThere were statistically significant differences in analyte concentration before and after high-speed centrifugation for: albumin, creatinine, GGT, glucose, phosphates, urea and total bilirrubin. Own LI is calculated. McNemar test shows statistically significant diferences in the proportion of delivered results before and after high-speed centrifugation in ALT, AST and creatinine.ConclusionsThis study confirms the efficacy of high-speed centrifugation protocol for all the considered analytes, excepting calcium, alkaline phosphatase and total proteins.

The United Nations Human Development Program has released its yearly study on the quality of life for people around the world. The U-N report was started in 1990 to measure the progress of nations based on the lives of their citizens.This year's report lists 173 countries. It is based on the length of time citizens are expected to live, their education level and the amount of money they earn. Norway was listed as the country providing the best     

The Construction of Meaning from Text: possible effects of different reading strategies

An examination is reported of the effect of differences in reading strategies on the construction of meaning from novel length text. Following a brief review of psychological theory relevant to the question of how particular strategies could constrain meaning construction, specific differences are hypothesised in relation to Orwell's classic tale, Animal Farm. The results of an experimental examination using post‐graduate Diploma in Education students as subjects, and multidimensional scaling as the analytic technique, support the contention that reading strategies are important in the construction of differential meanings. The educational implications of the results are discussed in relation to the change in school practice from teacher‐directed reading to students reading more books but on their own or in small groups, without direct teacher intervention.     

Shaping the professional landscape through research,advocacy and education – an Australian perspective

This article is the first in a new series in this regular feature. The intention of the series is to look at important global developments in health science libraries. Librarians will be invited to share with HILJ readers key initiatives in their country or region. These articles should serve as a road map, describing the key changes in the field and exploring factors driving these changes. We initiate this series with an article by three Australian librarians who use research findings to depict the evolving professional landscape in their country. The starting point of their analysis is a report completed in 2011 which looked into likely future workforce and education requirements for health library professionals. The authors trace the achievements since then, most notably in the areas of research, advocacy and education. Clearly, a great deal has been achieved leading to a greater return on investment. The authors maintain that the key to shaping the profession and enhancing the status of librarians is ongoing professional development. To this end, Australia is promoting a systematic, competency based health specialist certification. Finally, they identify trends impacting on health librarianship, such as the growing importance of research data management and consumer health literacy. JM     

Exploring the Cautionary Attitude Toward Wikipedia in Higher Education: Implications for Higher Education Institutions

This article presents the research findings of a small-scale study which aimed to explore the cautionary attitude toward the use of Wikipedia in the process of learning. A qualitative case study approach was taken, using literature review, institutional documentation, and semi-structured interviews with five members of academic teaching staff from a UK Business School. Analysis found the reasons for the cautionary attitude were due to a lack of understanding of Wikipedia, a negative attitude toward collaborative knowledge produced outside academia, and the perceived detrimental effects of the use of Web 2.0 applications not included in the university suite.     

Poor relations in the preschool family: the funding of playgroups 1

Playgroups provide for more children under five than any other preschool service, and now regard themselves as an alternative to, rather than a substitute for, nursery education. There are, however, a number of major issues concerning their funding: income depends largely on parental fees and fund‐raising; playgroups are less well resourced than nursery education; and current resourcing may be too low to ensure quality. Based on research in 45 playgroups in three areas (rural, inner city, and suburban), the paper looks in more detail at the consequences for playgroups of their current funding position and, more specifically, at the impact on various aspects of playgroups ‐ including premises and equipment; opening hours and usage; the position of playgroup workers; the satisfaction of mothers and playgroup leaders; and the playgroup environment ‐ of different funding policies pursued by local authorities in the three study areas. One local authority provided substantial support to individual playgroups, while the other two gave minimal support. The paper concludes by considering three options for the future funding of playgroups.
