那天是1997年3月13日。我当时把车停进车库,然后走进厨房。那一刻,我震惊得完全哑口无言!窝在桌子上一个小花篮里的是一只可爱的杏色小贵宾狗,她直愣愣地盯着我看!毫无疑问,我对她一见钟情,而这种爱意一直延续,直至瞑目,直至永远。 相似文献

Research Findings: Child care delivery practices promoting continuous, primary caregiver-child relationships (relationship-focused child care) were evaluated for 223 preschool-age children (45% African American, 55% Latino) attending child care centers serving low-income children. Both relationship-focused and non-relationship-focused centers were accredited by the National Association for the Education of Young Children. Children in relationship-focused programs received more sensitive, involved, and affectionate caregiving and were more engaged with their caregivers than children in comparison centers, but some differences were greater for African American children. Outcomes associated with relationship-focused care included greater parent-reported child compliance and closer parent-caregiver relations, but no consistent benefits for cognitive school readiness, receptive language, or child behavior problems were found. Follow-up assessments were completed 1 year later for 119 children who remained in their programs. Social and cognitive outcomes improved over time, but some changes were moderated by child race/ethnicity and center type. Over time, parents reported greater child compliance and caregivers reported better parent-caregiver relationships in relationship-focused programs. Practice or Policy: Some social benefits of continuous, primary caregivers were found, but children's cognitive competencies improved with sustained attendance at these accredited programs regardless of the relationship-focused practices. 相似文献

Introduction:
Sample type recommended by the manufacturer for the digoxin Abbott assay is either serum collected in glass tubes or plasma (sodium heparin, lithium heparin, citrate, EDTA or oxalate as anticoagulant) collected in plastic tubes. In our hospital samples are collected in plastic tubes. Our hypothesis was that the serum sample collected in plastic serum tube can be used interchangeably with plasma sample for measurement of digoxin concentration. Our aim was verification of plastic serum tubes for determination of digoxin concentration.Materials and methods:
Concentration of digoxin was determined simultaneously in 26 venous blood plasma (plastic Vacuette, LH Lithium heparin) and serum (plastic Vacuette, Z Serum Clot activator; both Greiner Bio-One GmbH, Kremsmünster, Austria) samples, on Abbott AxSYM analyzer using the original Abbott Digoxin III assay (Abbott, Wiesbaden, Germany). Tube comparability was assessed using the Passing Bablok regression and Bland-Altman plot.Results:
Serum and plasma digoxin concentrations are comparable. Passing Bablok intercept (0.08 [95% CI = −0.10 to 0.20]) and slope (0.99 [95% CI = 0.92 to 1.11]) showed there is no constant or proportional error.Conclusion:
Blood samples drawn in plastic serum tubes and plastic plasma tubes can be interchangeably used for determination of digoxin concentration. 相似文献6.

Preanalytical phase is the most vulnerable part of the total testing process and is considered to be among the greatest challenges to the laboratory professionals. However, preanalytical activities, management of unsuitable specimens and reporting policies are not fully standardized, nor harmonized worldwide. Several standards related to blood sampling and sample transportation and handling are available, but compliance to those guidelines is low, especially outside the laboratory and if blood sampling is done without the direct supervision of the laboratory staff. Furthermore, for some most critical procedures within the preanalytical phase, internationally accepted guidelines and recommendations as well as related quality measures are unfortunately unavailable. There is large heterogeneity in the criteria for sample rejection, the different strategies by which unacceptable samples are managed, processed and test results reported worldwide. Management of unacceptable specimens warrants therefore immediate harmonization. Alongside the challenging and long road of patient safety, preanalytical phase offers room for improvement, and Editors at Biochemia Medica Journal definitely hope to continue providing a respective mean for reporting studies on different preanalytical phase topics. With pleasure and delight we invite potential future authors to submit their articles examining the quality of various preanalytical activities to Biochemia Medica. We will keep nurturing this topic as our prominent feature and by this we hope to be able to deliver valid evidence for some future guidelines and recommendations. 相似文献

Phlebotomy is one of the most complex medical procedures in the diagnosis, management and treatment of patients in healthcare. Since laboratory test results are the basis for a large proportion (60–80%) of medical decisions, any error in the phlebotomy process could have serious consequences. In order to minimize the possibility of errors, phlebotomy procedures should be standardised, well-documented and written instructions should be available at every workstation. Croatia is one of the few European countries that have national guidelines for phlebotomy, besides the universally used CLSI (Clinical Laboratory Standards Institute) H3-A6 Procedures for the Collection of Diagnostic Blood Specimens by Venipuncture; approved Standard-Sixth Edition (CLSI, 2007) and WHO (World Health Organization) guidelines on drawing blood: best practices in phlebotomy (WHO, 2010). However, the growing body of evidence in importance of preanalytical phase management resulted in a need for evidence based revision and expansion of existing recommendations.The Croatian Society for Medical Biochemistry and Laboratory Medicine, Working Group for the Preanalytical Phase issued this recommendation. This document is based on the CLSI guideline H3-A6, with significant differences and additional information. 相似文献

This article describes research exploring the relationship between students’ self-perceptions in the context of university learning (i.e. student social identity), their approaches to learning, and academic achievement. The exploration of these inter-related aspects requires a mix of theoretical approaches, that is, in this research both social identity perspective from social psychology and the student learning research framework are used to explore student identity and learning in the context of higher education. Two structural equation models drawing on both these theoretical frameworks were tested. In the first of these models, deep approaches to learning are positively associated with students’ social identification as university student and positively predict academic achievement. In the second model, surface approaches to learning are negatively associated with students’ social identification and negatively predict academic achievement. The mediational roles of deep and surface approaches to learning in the relationship between student social identity and academic achievement are also explored. 相似文献
