Crying Therapy Intervention for Breast Cancer Survivors: Development and Effects.

BACKGROUND: crying therapy is currently being applied in some countries to treat cancer patients, manage pain, and promote mental health. However, little nursing and medical research on the effects of crying therapy has been conducted in other parts of the world. This study aimed to develop a crying therapy program for breast cancer survivors and assess its effects. Interventions/method: data from 27 breast cancer survivors in South Korea were analyzed. The intervention, employing a single group, pre-post-test quasi-experimental design, was divided into three phases, and effects were verified for emotional (distress, fatigue, and mood conditions) and physiological (cortisol, immunoglobulin G, and blood pressure) variables. RESULTS: there were significant changes in distress, mood changes, and immunoglobulin G and smaller changes in blood pressure postintervention. Fatigue and cortisol showed no significant changes. CONCLUSIONS: this study demonstrated the effectiveness of a short-term crying therapy program that can induce positive emotional changes and physiological effects in breast cancer survivors. This intervention can improve quality of life, indicating its value as a self-care program for cancer survivors.

Experiences of Changes in Cognitive Function for Women treated with Chemotherapy for Breast Cancer.

PURPOSE: The purpose of this study was to describe the experiences of the process of the change in cognitive function for women treated with chemotherapy for breast cancer. METHODS: There were ten participants in total in this study. Data were gathered utilizing in-depth interviews over 3 times from September 2010 to January 2011. Data were analyzed by employing Strauss and Corbin's (1998) grounded theory methodology. RESULTS: Findings indicate that causal conditions of these results were 'side effects of chemotherapy' and 'menopausal state', including contextual conditions as, 'mental fatigue' and 'anxiety about recurrence'. The core category was identified as 'confronting with unexpected chaos'. Intervening conditions were 'support from other people', 'lack of information on cognitive impairment'. Interaction strategies were 'changing the habit of life', 'making efforts for living life' and 'seeking for medical information'. Consequences of the process were 'physical restriction', 'difficulty in social life', 'disturbed working ability' and 'psychological distress'. CONCLUSION: The results of this study show that nurses should recognize there is a notable difference between individual patient's contextual conditions and interactive strategies. Furthermore educational information and individualized intervention should be provided to improve cognitive function for women with breast cancer.

Effects of gomisin A on vascular contraction in rat aortic rings.

Gomisin A (GA) is an active ingredient of the fruits of Schisandra chinensis which has been widely used as a tonic in traditional Korean medicine. GA induces not only endothelium-dependent but also endothelium-independent relaxation in an isolated rat's thoracic aorta. This study was aimed to investigate the molecular mechanism by which GA induces endothelium-independent vasorelaxation. Rat aortic rings were denuded of endothelium, mounted in organ baths, and subjected to contraction or relaxation. We measured the amount of GTP RhoA as well as the phosphorylation level of 20 kDa myosin light chains (MLC20), myosin phosphatase-targeting subunit 1 (MYPT1) and protein kinase C-potentiated inhibitory protein for heterotrimeric myosin light-chain phosphatase of 17 kDa (CPI17). Pretreatment with GA dose-dependently inhibited the concentration-response curves in response to sodium fluoride (NaF) or thromboxane A(2) agonist U46619, but not to phorbol 12, 13-dibutyrate (PDBu). GA decreased the activation of RhoA as well as the phosphorylation level of MLC20, MYPT1(Thr855), and CPI17 induced by 8.0 mM NaF or 30 nM U46619. However, K+ channel blockers such as glibenclamide, apamin, or charybdotoxin did not affect the vascular relaxation induced by GA. Furthermore, GA did not affect the level of phosphorylation of CPI17 induced by PDBu. GA reduces vascular contraction through inhibition of RhoA/Rho-kinase pathway in endothelium-denuded rat aorta.

[Development of a critical thinking disposition scale for nursing students].

PURPOSE: The purpose of this study was to develop a critical thinking disposition scale for nursing students. METHOD: The developmental process was construction of a conceptual framework, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity and extraction of final items. The conceptual framework and first preliminary 60 items were obtained through a review of relevant literature and the development of critical disposition scales by 10 researchers who had been studying critical thinking for one year. These items were reviewed by five specialists for content validity and finally 55 items were chosen. The data was collected from October 1 to 15, 2004 and was analyzed using factor analysis and Cronbach's alpha with the SPSS program. The subjects were composed of 560 Bachelor of Science nursing students from 8 nursing schools. RESULT: There were 35 final items which were sorted into 8 factors. The factors were identified as 'intellectual integrity(6 items)', 'creativity(4 items)', 'challenge(6 items)', 'open-mindedness(3 items)', 'prudence(4 items)', 'objectivity(4 items)', 'truth seeking(3 items)' and 'inquisitiveness(5 items)'. The cumulative percent of variance was 55.107%. The reliability of the scale, Cronbach's alpha was .892 and the factors' ranged from .562-.836. CONCLUSION: The result of this study could be used for measuring critical thinking dispositions of nursing students. However, for further validity and reliability, repeated research is necessary.
