Ineffectiveness of the Tobacco Hazards Prevention Act in patients with severe and persistent mental illness.

OBJECTIVES: The effect of the Tobacco Hazards Prevention Act (THPA) on the reduction of tobacco use in the general population in Taiwan is understood. However, there has been little research on how these policies affect people with severe and persistent mental illness (SPMI). Hence, the influence of the THPA on daily cigarette use by patients with SPMI was investigated in a 3-year follow-up. The risk and protective factors in smoking behavior and cessation were investigated. STUDY DESIGN: This is an observational study. METHODS: A total of 144 participants (78 of whom had smoked >100 cigarettes throughout their lifetime) were randomly selected from a healthcare network. Then, 100 of 144 patients with SPMI, included 50 smokers and 50 non-smokers, have agreed with 1st year follow-up. Eighty-two patients with SPMI, consisted of 44 smokers and 38 non-smokers, have agreed with 2nd year follow-up. RESULTS: Although women were less likely to smoke than men, those who did smoke reduced the number of cigarettes less than men over the 3-year period. Less-educated patients were more likely to smoke than those who were more educated but reduced the number of daily cigarettes more after implementation of the THPA. Maternal overprotection was a risk factor and paternal care a protective factor for smoking. Addiction, a perception of pleasure, interpersonal relationships, and self-destructive behavior increased cigarette smoking. Patients perceived that smoking alleviated their depressive symptoms. CONCLUSIONS: The THPA was ineffective for patients with SPMI. Some factors had different effects on the development of smoking behavior and the cessation process. Understanding the etiology of smoking can help policymakers establish more effective programs for smoking prevention and cessation.

Factors associated with osteoporosis in patients with chronic obstructive pulmonary disease-a nationwide retrospective study.

The present study aimed to identify the factors associated with osteoporosis in patients with chronic obstructive pulmonary disease in Taiwan. The study found that female sex, old age, and use of a high dose of oral corticosteroids were significantly associated with osteoporosis in these patients. INTRODUCTION: Chronic obstructive pulmonary disease (COPD) is becoming an increasingly serious and prevalent issue worldwide. The treatment of COPD with long-term steroid use may cause osteoporosis and have significant influences on disability and mortality. However, few studies have evaluated the association between steroid use and osteoporosis in patients with COPD. The present study aimed to identify the factors, including demographic characteristics and steroid use (oral corticosteroids [OCSs], inhaled corticosteroids, and injected steroids), associated with osteoporosis in patients with COPD in Taiwan. METHODS: This was a retrospective case-control study. Data were obtained from the National Health Insurance Research Database from 1997 to 2009. Cox proportional hazard regression models were used to identify the factors associated with osteoporosis. RESULTS: The incidence of osteoporosis in the patients with COPD was 1343.0 per 100,000 person-years, the majority of patients were women (63.6 %), and the mean age of the patients was 72.5 years. In multivariate regression analysis, female sex, old age, and use of a high OCS dose with a defined daily dose (DDD) >56 (hazard ratio 1.85, 95 % confidence interval 1.52-2.26, P < .0001) exhibited significant independent associations with osteoporosis. CONCLUSIONS: Female sex, old age, and use of a high OCS dose with a cumulative DDD >56 are associated with osteoporosis in patients with COPD. Additionally, female patients >50 years old and male patients >70 years old have a higher risk of osteoporosis. Medical personnel should actively provide health education for the prevention of osteoporosis in these patients.

Mediating effects of social support and self-concept on depressive symptoms in adults with spinal cord injury.

STUDY DESIGN: Cross-sectional, correlational design. OBJECTIVES: To examine the effects of individual demographics, activities of daily living, social support, and self-concept on depressive symptoms in people with spinal cord injury (SCI). SETTING: A convenience sample of 135 adults with SCI was recruited from medical and rehabilitation centres in Taiwan. METHODS: Face-to-face, structured interviews were employed to collect information. Study questionnaires included a demographic sheet, the Barthel scale, the modified Social Support Inventory, the Huang self-concept scale and the Beck Depression Inventory. Data were analysed by structural equation modelling (SEM). RESULTS: The average age of the participants was 43.3 years (±11.98), the mean duration of injury was 114 months (±93.78), and most were males. Emotional support (r=-0.173, P<0.05) and appraisal support (r=-0.261, P<0.01) were negatively correlated with depressive symptoms. The best fitted SEM model included individual demographics and physical function, social support and self-concept as significant predictors of depressive symptoms, with self-concept acting as a mediator in this relationship. Participants' characteristics and social support both contributed substantial indirect effects on depressive symptoms via self-concept. Self-concept also mediated the relationship between education, income, physical functioning and participants' depressive symptoms. CONCLUSION: For this sample, the more negative that individuals perceived themselves, the more likely they were to report worsening depressive symptoms. The more social support that individuals have, the more likely they were to report less depressive symptoms. Further longitudinal research will help clarify the direction of these relationships.

Decreased renal mRNA expression of TRPM6 is associated with hypomagnesemia in C57BL/6 asthmatic mice.

BACKGROUND AND OBJECTIVES: Hypomagnesemia has been reported up to 40% in asthma patients, and a relationship between hypomagnesemia and asthma severity has been previously characterized. However, the mechanism for hypomagnesemia in asthma patients is not clear. Transient receptor potential melastatin 6 (TRPM6) is a newly identified channel that is involved in active epithelial magnesium transport, and downregulation of TRPM6 in the kidney was related to reduced Mg2+ reabsorption in mouse model. The aim of the study was to investigate whether plasma and erythrocyte magnesium levels were correlated with renal expression of TRPM6 mRNA in C57BL/6 asthmatic mice. MATERIALS AND METHODS: 48 healthy C57BL/6 mice were randomly divided into asthmatic group and control group with 24 mice in each group. Each group were randomly taken out 8 mice at 1d, 21d, 34d to detect plasma Mg2+, intracellular Mg2+ and renal TRPM6 mRNA expressions. RESULTS: There were no significant difference in plasma Mg2+, intracellular Mg2+ and TRPM6 mRNA expression of renal tissues between asthmatic group and control group at 1d. However, plasma Mg2+ and intracellular Mg2+ as well as TRPM6 mRNA of renal tissues in asthmatic group were significantly lower than that of control group at 21d and at 34d. Both plasma Mg2+ and intracellular Mg2+ were positively correlated with TRPM6 mRNA expression in the renal tissues. CONCLUSION: This study indicates that the consistently reduced expression of TRPM6 mRNA may play a role in the pathogenesis of hypomagnesemia in C57BL/6 asthmatic mice.

[Coping behaviors of the elderly with positive physical examination results in Kaohsiung City].

The objectives of this study were as follows: first, to investigate the coping behaviors of the elderly facing the stress of disease after free physical examination; Second, to identify personal and disease characteristics, and the social support that influences coping behaviors in the elderly. The study sample consisted of 661 elderly patients who were found to have abnormal findings during a free physical examination provided by 11 regional health stations in Kaohsiung City. Data were collected with questionnaires through home interview. Four hundred and eighty-four subjects completed the questionnaires. Data were analyzed using SAS computer program. The major findings were as follows: 1.Problem-oriented coping behaviors were the more frequently used. The most frequently used coping behaviors were "accepting the situation as it is", "reling on myself to solve problems", "hoping that things would get better", "seeking professional help", and "letting things follow their natural cause". 2. The relative variables for problem-oriented coping were marital status, religion, medical insurance, educational level, disease characteristics, and social support. Sex, marital status, religion, medical insurance, perceived disease severity, characteristics of health problem, and newly found abnormality at this free physical examination were the relative variables for affective-oriented coping. 3. The best predictive variables for using problem-oriented coping behaviors were medical insurance, self-esteem support from family and friends, tangible support from health professionals, emotional support from health professionals, and whether it was the first time the patients knew their health problems. Findings from this study had implications for development of nursing care plans for elderly clients, as well as for collaborative team exploration of coping behaviors in the elderly.

[The utilization of health care by the elderly with chronic health problems in Kaohsiung City].

The purpose of this study was (1) to ascertain whether or not the elderly utilized the health care system and did follow-up after the initial free health check-up and screening; (2) to investigate the types of chronic health problems the elderly who utilize health care had and their reasons for using the health care system; and (3) to explore related factors that influence the utilization of health care by the elderly.
