Effects of an Off-Site Walking Program on Fibrinogen and Exercise Energy Expenditure in Women
Fumiko Furukawa,Keiko Kazuma,Michiyo Kojima,Reizo Kusukawa 한국간호과학회 2008 Asian Nursing Research Vol.2 No.1
Purpose Increased fibrinogen levels may trigger cardiac events in patients with atherosclerosis. Early control of fibrinogen levels before the progression of atherosclerosis that occurs with aging and menopause may benefit women, but the effects of exercise on fibrinogen levels as a preventive value have not been examined in early to middle adulthood women with lack of regular exercise. The present study aims to identify the effect of an off-site walking-based exercise program on fibrinogen levels in such women. Methods A prospective, 12-week, randomized and controlled study was used. Fifty-two women aged 32 to 57 years who did not exercise regularly or exercised with a weak intensity level were randomly assigned to either an intervention group (IG, n = 26) or a control group (CG, n = 26) for a 12-week study. Exercise energy expenditure (EEE) was measured using a microelectronic device. Fibrinogen levels were assessed using the clotting time method before and after the exercise program. Results The mean change from baseline EEE was 1.17 ± 0.98 kcal/kg/day in IG subjects (n = 24) and 0.46 ± 0.68 kcal/kg/day in CG subjects (n = 25), a 30% difference between groups (p = .01). The mean change in fibrinogen levels was –8.0 ± 34.5 mg/dl (3% decrease) in IG subjects (n = 24) and –3.6 ± 40.0 mg/dl (1% decrease) in CG subjects (n = 25). No significant difference in fibrinogen levels was seen between groups (F = 1.179, p = .279). Conclusion EEE increased significantly, but fibrinogen levels did not decrease significantly. The effects of a 12-week off-site walking program on fibrinogen levels were inconclusive. As implications for nursing practice, our findings have suggested fibrinogen levels are not a novel cardiovascular risk factor any more, and provide important information on safe exercise to minimize adverse effects from fibrinogen arising from exercise intensity, especially in women with advanced atherosclerosis when nurses increase exercise intensity levels. Further studies with larger sample sizes in women to confirm the effect of exercise on reducing fibrinogen levels are necessary.

Influences of Allocating HIV/AIDS Specialized Nurses on Clinical Outcomes in Japan
Masakazu Nishigaki,Yuko Sugino,Jongmi Seo,Megumi Shimada,Kazuko Ikeda,Keiko Kazuma 한국간호과학회 2011 Asian Nursing Research Vol.5 No.1
Purpose This retrospective cohort study was conducted to demonstrate how allocation of nurses specialized in HIV care influences clinical outcomes of antiretroviral therapy (ART) for people living with HIV (PLWH). Methods The medical records of 116 PLWH who started ART between January 2002 and December 2004 were analyzed. Occurrence of viral suppression and viral relapse after suppression achievement and their time from baseline were observed as clinical outcomes related to ART. Clinical outcomes were obtained from medical records between January 2002 and December 2006. PLWH were classified into two groups according to allocation (n = 95, nurse allocated group) or nonallocation (n = 21, nurse nonallocated group) of nurses specialized in HIV. Results Survival analysis showed that HIV viral load was suppressed more rapidly and continuously in nurse allocated group than nonallocated group (p < .0001). Viral relapse after suppression achievement occurred easily in nurse nonallocated group than allocated group (p = .003). Conclusions The present findings demonstrated that the role of specialized nurses is critically important from the viewpoint of clinical outcome. [Asian Nursing Research 2011;5(1):11–18]

Purpose The aim of this study was to evaluate the validity and reliability of the Seattle Angina Questionnaire, Japanese version (SAQ-J) as a disease-specific health outcome scale in patients with coronary artery disease. Methods Patients with coronary artery disease were recruited from a university hospital in Tokyo. The patients completed self-administered questionnaires, and medical information was obtained from the subjects’medical records. Face validity, concurrent validity evaluated using Short Form 36 (SF-36), known group differences, internal consistency, and test-retest reliability were statistically analyzed. Results A total of 354 patients gave informed consent, and 331 of them responded (93.5%). The concurrent validity was mostly supported by the pattern of association between SAQ-J and SF-36. The patients without chest symptoms showed significantly higher SAQ-J scores than did the patients with chest symptoms in 4 domains. Cronbach’s alpha ranged from .51 to .96, meaning that internal consistency was confirmed to a certain extent. The intraclass correlation coefficient of most domains was higher than the recommended value of 0.70. The weighted kappa ranged from .24 to .57, and it was greater than .4 for 14 of the 19 items. Conclusions The SAQ-J could be a valid and reliable disease-specific scale in some part for measuring health outcomes in patients with coronary artery disease, and requires cautious use.
