目的分析优质护理干预对帕金森患者心理情绪及生活质量的影响。方法 70例帕金森病患者,随机分为干预组与对照组每组患者35例。对照组患者采用常规护理干预,干预组患者采用优质护理干预。结果两组SDS和SAS评分干预后较干预前降低,均有显著性意义(P0.05);干预组SDS评分和SAS评分干预后低于对照组,均有显著性意义(P0.05);两组ADL和MMSE评分干预后较干预前增加,均有显著性意义(P0.05);干预组ADL和MMSE评分干预后高于对照组,均有显著性意义(P0.05);两组物质生活、社会功能、心理健康和躯体功能评分干预后较干预前增加,均有显著性意义(P0.05);干预组物质生活、社会功能、心理健康和躯体功能评分干预后高于对照组,均有显著性意义(P0.05)。结论优质护理干预可减轻帕金森患者负性情绪,及提高患者生活质量。 相似文献

The effects of the implementation of quality-management systems and technological changes on the performance of 23 Finnish clinical chemistry laboratories were studied in external quality-assessment (EQA) schemes organized by Labquality Ltd., Finland, during 1993 to 1999. The investigated serum analytes were sodium, calcium, glucose, cholesterol, and alanine aminotransferase. According to the results, the improvements in analytical quality due to the quality programs were rather small. The effects to the proportions of satisfactory results in terms of precision and deviation from the target value were 5–15% (95% confidence intervals for the proportions ±1–5%). At the same time the laboratories were implementing quality-management systems new technology and characteristics of quality-control materials affected the EQA performance. Both improvements and deteriorations in analytical quality due to these factors were identified. The effects and their total outcomes differed substantially between the five analytes. 相似文献

Ladybug taint (also known as ladybird taint) is a relatively recently recognized fault that has been identified in wines from a wide range of terroirs. Alkyl-methoxypyrazines—particularly 2-isopropyl-3-methoxypyrazine—have been determined as the causal compounds, and these are introduced into grape must during processing, when specific species of vineyard-dwelling Coccinellidae are incorporated into the harvested fruit. Coccinella septempunctata, and especially the invasive Harmonia axyridis, are the beetles implicated, and climate change is facilitating wider dispersal and survivability of H. axyridis in viticultural regions worldwide. Affected wines are typically characterized as possessing excessively green, bell pepper-, and peanut-like aroma and flavor. In this paper, we review a range of vineyard practices that seek to reduce Coccinellidae densities, as well as both “standard” and novel wine treatments aimed at reducing alkyl-methoxypyrazine load. We conclude that while prevention of ladybug taint is preferable, there are several winery interventions that can remediate the quality of wine affected by this taint, although they vary in their relative efficacy and specificity. 相似文献
