When work strain transcends psychological boundaries: an inquiry into the relationship between time pressure,irritation, work–family conflict and psychosomatic complaints

Against the theoretical background of the effort–recovery model and the action regulation theory, the author presents a cross‐sectional questionnaire study testing hypotheses about the relationship between work‐related time pressure, cognitive and emotional irritation, work–family conflict and psychosomatic complaints. Subjects were 576 female home care nurses. Results of a path analysis show that the relation of time pressure and psychosomatic complaints is partially mediated by experiencing a work–family conflict; also the relation of time pressure and work–family conflict is partially mediated by cognitive and emotional irritation. It is argued that cognitive and emotional irritation are fruitful concepts for a more comprehensive understanding of the relationship between work stressors and the development of strain‐based work–family conflict. Implications for the prevention of work–family conflict are outlined. Copyright © 2008 John Wiley & Sons, Ltd.     

17β-雌二醇对子宫内膜异位症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响

目的研究17β-雌二醇(17β-E2)对子宫内膜异位症(内异症)患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响,探讨Wnt/β-catenin信号通路在介导雌激素促进内异症发生发展的作用。方法体外分离培养内异症患者在位子宫内膜间质细胞。用不同浓度17β-E2处理子宫内膜间质细胞48 h;此后选用10-10mol/L 17β-E2处理子宫内膜间质细胞12、24和48 h,逆转录聚合酶链反应(RT-PCR)和免疫印迹法(Western blotting)检测17β-E2处理前后子宫内膜间质细胞β-catenin mRNA和蛋白的表达水平。同法分析雌激素受体拮抗剂ICI182,780(10-6mol/L)对17β-E2促进β-catenin mRNA和蛋白表达的影响。免疫组织化学染色观察17β-E2作用后β-catenin在子宫内膜间质细胞中的定位。结果17β-E2能明显促进内异症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白的表达,并呈剂量和时间依赖性,于10-10mol/L作用48 h最明显。雌激素受体拮抗剂ICI182,780能明显抑制17β-E2对子宫内膜间质细胞β-catenin mRNA和蛋白的表达。免疫组织化学染色发现17β-E2能促进β-catenin在子宫内膜间质细胞核内的表达。结论雌激素可能通过激活Wnt/β-catenin信号通路促进内异症在位子宫内膜的异位种植。     

Terminal home care in the Netherlands: An overview

Beginning in the late 1980s, after a long period of declining interest in home care for the terminally ill, several projects and experiments were initiated in the Netherlands. This article describes this trend and provides background information on the Dutch health services, a definition of terminal home care, and statistical information about the different types of home care in the Netherlands. Findings from 3 recent studies of these projects and experiments are presented along with the guidelines for providing good terminal home care formulated by the Dutch Health Council in 1991.

Preventing accidental injury to young children in the home using volunteers

Accidental injury in the home is a major cause of death andill-health among young children. Reducing home safety hazardsby the use of safety devices such as stair barriers and safetytaps has the potential to prevent home injuries. Little is knownabout levels of home safety hazards or how to encourage parentsto reduce hazards. The Safe Place Project examined parents'knowledge of home safety and the prevalence of safety hazardsin homes where there were young children. The study also evaluatedthe effectiveness of a low-cost strategy aimed at reducing homesafety hazards. The strategy used trained volunteers to providehome safety checks and tailored safety education in conjunctionwith increasing the availability of home safety devices. Onehundred and six families with young children participated inthe project. Some homes contained many hazards, with 43% ofthe sample having more than 10 home safety hazards. At follow-up,the intervention group showed a significant reduction in homehazards and a trend towards an increase in knowledge of homesafety.

Comparing hand-held computers and paper diaries for haemophilia home therapy: a randomized trial

Treatment of severe haemophilia with factor concentrates is by self-infusion in the home. Adherence to record keeping on paper diaries is poor. A randomized-controlled trial compared adherence with record keeping of paper diaries with hand-held computers. Forty-one individuals with severe haemophilia, were randomized to hand-held computers (n = 22) or paper diaries (n = 19) and followed for 6 months. About 86.2% (679 of 788) of infusions by patients in the computer group were in compliance with the data submission schedule compared with only 48.3% (358 of 741) of infusions by patients using paper diaries (P < 0.0001). The time intervals between infusions and the receipt of data were shorter in the computer group (median 0.25 vs. 25 days respectively, P < 0.0001). Reminder phone calls by the clinic were made less frequently to users of hand-held computers than to users of paper diaries (median one vs. five times, P < 0.0001). Accuracy of data was similar for both methods. Compliance with hand-held computers was superior to paper diaries. The clinic received data from hand-held computers mostly on the same day, and nurses could thereby provide clinical advice more effectively. Although hand-held computers did not result in increased accuracy, errors could be detected and corrected more rapidly. Electronic data can more easily be verified, analysed and summarized than that from paper diaries.
