目的：研究60岁以上老年人急性心肌梗塞的临床特点。方法：对86例老年人急性心肌梗塞资料进行临床分析,并与同期255例小于60岁的急性心肌梗塞病人进行对比。结果：老年急性心肌梗塞患者女性的比例较60岁以下者明显增多(P＜0.01),老年无痛性心肌梗塞比例(30.5%)明显增多(P＜0.05),并发症心力衰竭(P＜0.01)、心律失常(P＜ 0.05),死亡率(P＜0.01)也明显增多。结论：老年人无痛性急性心肌梗塞多见,并发症发生率、死亡率高,应予重视。     

实施人本管理打造医院核心竞争力

医疗机构在激烈的竞争中，要保证持续发展，关键在于培训核心竞争力。人才是医院最核心的竞争力，因此必须实施人本管理。要提升人力资源的价值，以正确的目标引导人，以科学的方式管理人，以完善的机制激励人，以战略的眼光培养人，以终生的培训塑造人，以优秀的文化武装人，建立一个自主自足，自我控制，自我发展，自我完善的管理机制，激发全院员工的创造力，增强医院的凝聚力，人尽其才，才尽其用，提高工作效率，以提升医院效益。

The pathological diagnosis of the tumor was confirmed as cardiac fibroma. His postoperative course was uneventful and he is currently well with no signs of recurrence 2 years after surgery.     

不同膳食特点地区中老年人血红蛋白及其与膳食营养的关系

测定分析不同膳食特点地区975例年龄45～74岁中老年人的血红蛋白及其与膳食营养素的关系。结果牧民及城市居民贫血率低，北京及新疆托里分别为7.6％和4.6％。男性比女性血红蛋白高，血红蛋白随年龄增加而降低。相关分析结果血红蛋白与膳食热能、蛋白质、动物蛋白质与总蛋白质比值呈显著正相关。结果说明血红蛋白可用于中老年人营养状态监测。     

Low levels of essential fatty acids are related to impaired delayed skin hypersensitivity in malnourished chronically ill elderly people

Abstract Essential fatty acid (FA) deficiency, which may accompany protein-energy malnutrition (PEM), has been associated with impaired inflammatory reactions. We evaluated this relationship by analysing FA profiles and delayed cutaneous hypersensitivity in 20 malnourished elderly non-cancer patients and in 20 age-matched control patients. As indicated by serum cholesterol and serum triglycerides, the lipid levels were decreased by about one-third in the subjects with PEM. In comparison with the controls, there was a reduction in the ω 3 FA (e.g. eicosapentanoate) in total serum lipids (mgl^-1) and serum phospholipids (%) of 40% and 47%, respectively. Reductions in serum ω 6 FA (e.g. linoleate and arachidonate) levels corresponded to the drop in total FA concentrations (30%). The cutaneous hypersensitivity was impaired in 14 of the malnourished patients. The magnitude of the skin reaction was positively correlated ( P < 0·05) to the concentrations of eicosapentanoate in serum lipids and serum phospholipids, as well as to the linoleate concentration in total serum lipids. Six of the malnourished patients took part in a nutritional intervention programme for 3 months. In parallel with an improvement in the nutritional status there was a 35% increase ( P < 0·05) in the total ω 3 FA serum concentration. Negative skin tests became positive and the median skin induration enlarged threefold ( P < 0·05). Thus, deficiency of ω 3 FA might be one factor contributing to cutaneous anergy in elderly malnourished patients.     

Dietary intake in the elderly estimated by a 24 hour recall and a food frequency questionnaire

Two hundred and thirty-five tenants living in sheltered housing in Scotland were surveyed to identify the extent of under-nutrition and the social factors which contribute to its development. A validated 24 h recall and the nutrient checklist published by NAGE were used to evaluate patterns of dietary intake. A questionnaire was developed which included scales designed to measure depression, social engagement, cognitive function, mobility and functional ability. The results show considerable evidence of a number of major nutrients in which there were low intakes. In order to express the extent of poor nutrition, a nutrient score was developed where points are awarded based on the number of nutrients falling below the Lower Reference Nutrient Intake, the Estimated Average Requirement or below half the daily Estimated Average Requirement.

Promoting autonomy and independence for older people within nursing practice: a literature review

The principles of promoting autonomy and independence underpin many approaches to improving the quality of nursing care for older people in whatever setting, and are in line with wider developments in health care such as the Patient's Charter. However, these concepts require careful definition if nursing practices which might promote autonomy and independence are to be identified. Although the generalizability of the research-based literature in this field is limited by a focus upon older people in continuing-care settings, a review of the literature found a number of indicators associated with attempts to promote patient autonomy and independence. These were grouped into the following categories: systems of care delivery which promote comprehensive individualized assessment and multidisciplinary care planning; attempts to encourage patients/clients to participate in decisions about their care; patterns of communication which avoid exerting power and control over patients/clients and attempts to modify the environment to promote independence and minimize risk. It is suggested that the review identifies a number of principles for nursing practice which can be applied in a range of care settings in order to promote the autonomy and independence of older people.     

‘You have to learn to live with it’: a qualitative and quantitative study of older people with asthma

Introduction: Asthma mortality has declined overall because of a range of public health initiatives. In western countries, the majority of asthma deaths now occur in people over the age of 50. The reasons for the poorer response of older age groups to public health asthma initiatives are not known. Objectives: We undertook a study to investigate the disease perspectives of older people with asthma and barriers which may exist and prevent optimal asthma care. Methods: Fifty‐five participants (16 male and 39 female) aged over 50 from an inner city, suburban area and a rural region were recruited. Lung function was measured, and questionnaire data on asthma symptoms, knowledge and control, medication use and respiratory health were collected. Participants were also interviewed in‐depth, and the quantitative and qualitative data were triangulated. Results: Participants with a duration of asthma for >30 years reported significantly fewer symptoms and better quality of life irrespective of asthma severity, indicating less appreciation of symptoms in those with a long asthma duration. Interviews revealed this was related to previous asthma management strategies when treatment options were limited. Participants with a recent diagnosis sought understanding of asthma and the reason for their illness. Initiatives to improve asthma care in older people need to reflect these findings. Conclusions: Self‐management strategies for older people need to be tailored according to the time of disease onset and the duration of disease.
