    ABSTRACT: Aims and objectives.  To assess the effects of respiratory training on lung function, activity tolerance and quality of life in patients with chronic obstructive pulmonary disease. Background.  For patients with chronic obstructive pulmonary disease, pulmonary rehabilitation can increase activity tolerance and improve their psychological state by relieving dyspnoea and promoting their quality of life. Design.  A randomised clinical trial was conducted in a local hospital. Methods.  Patients with chronic obstructive pulmonary disease were randomly assigned to intervention (n = 20) and control groups (n = 20). Spirometry, six-minute walking distance and quality of life were used to assess the efficacy of respiratory training programme. Results.  Significant improvement in lung function, including forced vital capacity (p = 0·037), forced expiratory volume in one-second (p = 0·006) and per cent predicted forced expiratory volume in one-second (p = 0·008) in the intervention group. Regarding efficacy of the training programme for patients with chronic obstructive pulmonary disease, in forced expiratory volume in one-second (p = 0·024) and per cent predicted forced expiratory volume in one-second (p = 0·035), six-minute walking distance significantly increased. In addition, there were significant improvements for symptoms (p = 0·018), impact (p < 0·001) and total quality of life scores (p < 0·001), as well as significantly decreased body mass, airflow obstruction, dyspnoea and exercise capacity index (p = 0·004) in the intervention group. Conclusions.  A respiratory training programme for patients with chronic obstructive pulmonary disease was found to relieve dyspnoea, maintain lung function, increase activity tolerance and improve quality of life. Relevance to clinical practice.  Respiratory training programme can be used as a routine rehabilitation protocol for patients with chronic obstructive pulmonary disease and can be used by nurses as a reference to monitor chronic obstructive pulmonary disease patients' health status.

    ABSTRACT: The more support elderly people have from their family, the less likely they are to suffer from chronic diseases. The objective of this study is to investigate how family support affects the PA middle-aged and elderly people engage in before and after they suffer from chronic diseases. We interviewed 428 middle-aged and elderly people using a structured questionnaire to measure their aerobic PA. Eighteen percent of middle-aged and elderly people did participate in PA after suffering from chronic diseases. Using multivariate logistic regression models, we found that middle-aged and elderly people who rely on family members when they are sick (OR=1.87, 95%CI=1.08-3.25) and who are accompanied by family members (OR=2.09, 95%CI=1.20-3.62) when they are healthy are more likely to exercise. The more middle-aged and elderly people are supported by their family, the more likely they are to exercise. Strengthening family relationships should help reduce the prevalence of chronic diseases among middle-aged and elderly people.

    ABSTRACT: The use of health care services by older adults is increasing with the aging of the population. It is therefore essential that health care workers are current in their knowledge about gerontology; thus, educational programs regarding the care of elders are essential. Chinese-language assessments to measure knowledge about gerontology and aging and attitudes toward older adults are lacking. This study was designed to measure the reliability and validity of a Chinese-language version of Palmore's facts on aging quiz (FAQ 1). Cronbach's alpha, construct validity, content validity and convergent validity of the Chinese version of the FAQ 1 were assessed. A sample of 220 student nurses was recruited. Part of the sample (n=125; Group A) was comprised of experienced nurses who had returned to school for advanced degrees. The remaining 95 participants were first-year undergraduate students without prior work experience (Group B). The FAQ 1 was administered to all participants. The Chinese-language version of Kogan's Attitudes toward Older People (KAOP) was also administered to assess convergent validity of the FAQ 1. Cronbach's alpha of the FAQ was 0.68, content validity was 0.82, and construct validity and convergent validity were acceptable. Group A had more correct answers on each item than Group B, indicating that students with prior work experience with the elderly were more knowledgeable regarding older people and aging. Based on the results of the assessment, the Chinese version of FAQ 1 is a valid and reliable instrument for measuring students' or health care providers' knowledge about older people.

    ABSTRACT: Purpose The purpose of this study was to examine the influences of psychological well-being, quality of caregiver-patient relationship, and family support on the health of family caregivers for cancer patients in a Taiwanese hospital. Methods A cross-sectional, correlational design was used. A sample of 91 family caregivers of hospitalized cancer patients completed the Caregiver Reaction Assessment and Psychological Well-Being Scale. Pearson's product moment correlation and regression analyses were used to examine the data. Results The psychological well-being and the quality of the caregiver-patient relationship of family caregivers were found to be significantly positively correlated with caregivers' health. The lack of family support was found to be significantly negatively correlated with caregivers' health. Psychological well-being, quality of caregiver-patient relationship, and family support accounted for 59% of the variance in caregivers' health. Conclusion The findings suggest that nurses, while providing care in the hospital and upon discharge need to be aware of the psychological well-being, quality of caregiver-patient relationship, and family support of a family caregiver, as these factors all have an impact on a family caregiver' health.

    ABSTRACT: The relationship between cigarette smoking and cognitive impairment is not a simple one. Some studies have demonstrated that cigarette smoking is a risk factor for cognitive impairment in the elderly, whereas other studies have shown cigarette smoking to be protective against dementia. This study aims to explore the relationship between cigarette smoking and cognitive impairment in elderly persons without dementia, during a 10-year period. Data were derived from a population-based cohort study of 1436 elderly Taiwanese. Cognitive function was measured by the SPMSQ both in 1993 and in 2003. A total of 1436 participants free of cognitive impairment at baseline (SPMSQ> or =6 in 1993) were included in these analyses. Subsequently, participants were divided into three groups: never, past, and current smokers. The effect of cigarette smoking on cognitive function was assessed using logistic regression. In the logistic regression model adjusted for age, education, hypertension, diabetes, heart disease, and stroke at baseline, persons who had quit smoking (Odds ratio=OR=0.31; 95% CI=0.18-0.53; p<0.001) and those who continued to smoke (OR=0.37; 95% CI=0.20-0.70; p<0.001) were about one-third as likely to develop cognitive impairment as were those who never smoked. However, no dose-response relationship was observed between pack-years and cognitive impairment. Past and current smokers were less likely to develop cognitive impairment during a 10-year follow-up than were those who had never smoked. The present study suggests that smoking may be protective for cognitive function.

    ABSTRACT: To assess the effects of exercise intervention on nurses' health-related physical fitness. Regular exercise that includes gymnastics or aerobics has a positive effect on fitness. In Taiwan, there are not much data which assess the effects of exercise intervention on nurses' health-related physical fitness. Many studies have reported the high incidence of musculoskeletal disorders (MSDs) in nurses However, there has been limited research on intervention programs that are designed to improve the general physical fitness of nurses. A quasi-experimental study was conducted at a medical centre in central Taiwan. Ninety nurses from five different units of a hospital volunteered to participate in this study and participated in an experimental group and a control group. The experimental group engaged in a three-month intervention program consisting of treadmill exercise. Indicators of the health-related physical fitness of both groups were established and assessed before and after the intervention. Before intervention, the control group had significantly better grasp strength, flexibility and durability of abdominal muscles than the experimental group (p < 0.05). After the intervention, logistic regression was used to adjust for marital status, work duration, regular exercise and workload and found that the experimental group performed significantly better (p < 0.05) on body mass index, grasp strength, flexibility, durability of abdominal and back muscles and cardiopulmonary function. This study demonstrates that the development and implementation of an intervention program can promote and improve the health-related physical fitness of nurses. It is suggested that nurses engage in an exercise program while in the workplace to lower the risk of MSDs and to promote working efficiency.

    ABSTRACT: The elderly population will approach 20% within the next 20 years. This enhances the need for skilled and experienced health care providers. There is a critical need to strengthen gerontology curricula to prepare health-related professionals for a graying population. The purpose of this article is to investigate student satisfaction with the first National Project for Excellence in Gerontological Care Education (NPEGCE) in Taiwan. A cross-sectional design was used. A sample of 151 medical, nursing, and physical therapy students, who had enrolled in the NPEGCE and had taken at least one core course, completed a satisfaction questionnaire. To ensure content validity, a multidisciplinary, institutional committee of gerontology and geriatric faculty designed the content. Overall satisfaction scores varied between satisfied (4-points) and very satisfied (5-points). Medical students gave higher ratings than others. Two factors (Curriculum and Teaching) were extracted. A strong correlation was found between the subscales and overall satisfaction scores. Internal scale consistency reliability scores ranged from 0.92 to 0.96. Overall, this study demonstrates a moderate level of satisfaction with the NPEGCE. However, these results are from a single institution; they are not generalizable. This is also the first student satisfaction report from Taiwan. There are no similar programs or evaluation results to compare them with. Since the NPEGCE was well received by students and seemed to encourage a more nurturing attitude towards the elderly; it can be regarded as a catalyst for better elderly care in the future.

    ABSTRACT: The aim of the current study was to investigate whether changes in post- to pre-overnight sleep systolic blood pressure (SSBP) are associated with sleep respiratory disturbance, pro-inflammatory state, and metabolic situation in patients with sleep-disordered breathing (SDB). Anthropometry, sleep polysomnography, biochemical markers, and pre- and post-overnight sleep BP were measured from 263 SDB patients. All SDB patients were further subgrouped into MORNING SURGE (% changes from post- to pre-overnight SSBP >+1SD of this cohort), MORNING DROP (% changes <-1SD), CONSTANT HIGH (% changes within+/-1SD, averaged SSBP>130mmHg) and CONSTANT LOW (% changes within+/-1SD, averaged SSBP<130mmHg). BMI, neck circumference, waistline circumference, respiratory disturbance index, arousal index, lowest oxygen saturation, duration of SaO(2)<90%, blood glucose, hs-CRP, and metabolic syndrome score in MORNING SURGE and CONSTANT HIGH were significantly greater than those in CONSTANT LOW. Except metabolic syndrome score, all other parameters in MORNING DROP were similar to those in CONSTANT LOW. Patients with SDB whose post- to pre-overnight SSBPs were elevated or maintained a constant high have more sleep respiratory disturbance, more pro-inflammatory state, and higher metabolic syndrome indices than the rest. Without subdividing into CONSTANT LOW, MORNING DROP, CONSTANT HIGH, and MORNING SURGE, the important pathophysiologic points of SDB patients will possibly be missed.
