ABSTRACT
Background: Coronary artery diseases and therapies such as coronary angioplasty would lead to changes in the quality of life in patients. The aim of this study was to determine the effects of collaborative care model on the quality of life in patients after coronary angioplasty
Methods: This randomized controlled clinical trial was conducted in Isfahan, Iran during 2015. In this study, 50 samples were selected by simple sampling and randomly allocated into two equal groups of intervention and control. Collaborative care model was performed in the intervention group for 3 months. Data were collected using quality of life [SF-36] questionnaire which includes 36 questions on physical and psychological dimensions and was completed before and one month after the intervention in both groups. Data were analyzed using descriptive and analytical statistics and by independent t- test, paired t test, Chi square and Mann-Whitney tests through SPSS 18
Results: After the intervention, the mean score of quality of life in the intervention group was significantly higher than the control group [P<0.05]. The results of independent t-test showed a significant difference between both groups regarding the mean of changes in the score of quality of life and its dimensions in patients undergoing coronary angioplasty 3 months after the intervention [P<0.001]
Conclusion: Results revealed that patients who had been cared based on collaborative care model had better scores of quality of life in all the physical, mental and social dimensions than the control group. Therefore, using this model for taking care of patients after coronary angioplasty is recommended
ABSTRACT
Background: lack of knowledge, attitude and practice are some of the barriers of having a healthy lifestyle and controlling high blood pressure. This study aimed to determine the effectiveness of a lifestyle modification program on knowledge, attitude and practice of hypertensive patients with angioplasty
Methods: this study was a randomized controlled clinical trial conducted from November to April 2014 on 60 hypertensive patients with angioplasty in Shahid Chamran hospital of Isfahan, Iran. The samples were randomly assigned to two equal groups. Data collection was performed in three stages by a researcher-made questionnaire. The intervention plan was 6 education sessions and then follow up were done by phone call. The gathered data were analyzed via SPSS [V.20], using t-test, Chi-square, repeated measurement, and post hoc LSD test and ANOVA statistics
Results: the mean score of knowledge, attitude and practice in the experimental group immediately after the intervention was 77.8+/-7.2, 88.3+/-6.4 and 86.2+/-6.5, respectively and one month after the intervention was 80.8+/-7.4, 91.1+/-3.5 and 92.5+/-2.2, respectively. But in the control group, the mean score of knowledge, attitude and practice immediately after the intervention [34.90+/-11.23, 61.11+/-6.28, and 38.64+/-7.15] and one month after the intervention was [38.64+/-7.15, 59.56+/-6.31 and 37.27+/-7.26
Conclusion: lifestyle modification program can be effective in promoting the knowledge, attitude and practice of hypertensive patients with angioplasty. Nurses can use this program in their care provision programs for these patients
ABSTRACT
Main suggested theories about patients' adherence to treatment regimens recognize the importance of motivation in positive changes in behaviors. Since cardiac diseases are chronic and common, cardiac rehabilitation as an effective prevention program is crucial in management of these diseases. There is always concern about the patients' adherence to cardiac rehabilitation. The aim of this study was to describe the motivational factors affecting the patients' participation and compliance to cardiac rehabilitation by recognizing and understanding the nature of patients' experiences. The participants were selected among the patients with cardiac diseases who were referred to cardiac rehabilitation in Isfahan Cardiovascular Research Center, Iran. The purposive sampling method was used and data saturation achieved after 8 semi-structured interviews. The three main concepts obtained from this study are "beliefs", "supporters" and "group cohesion". In cardiac rehabilitation programs, emphasis on motivational factors affects the patient's adherence. It is suggested that in cardiac rehabilitation programs more attention should be paid to patients' beliefs, the role of patients' supporters and the role of group-based rehabilitation.
ABSTRACT
Changes in chloride cell abundance, Na+, K+-ATPase immunolocalization and activity were investigated in the gills of the golden grey mullet, Liza aurata, fry acclimated to freshwater [FW] and different salinities [12', 36' and 46%]. Na+, K+-ATPase localization was performed through immunofluorescence light microscopy using a mouse monoclonal antibody IgG alpha 5. Quantitive analysis of Na+, K+-ATPase intensity was analyzed using Optima's version 6.51 image analysis software [Media Cybernetics, Silver Spring, MD, USA]. In FW, the fluorescent cells [chloride cells] were observed on the epithelia of filaments [mainly in inter-lamellar regions] and on the lamellae. Following transfer to 12%. salinity, the abundance of Na+, K+-ATPase immunofluorescence cells on the filaments decreased 1.7-fold, and no immunofluorescence cells were detected on the lamellae. Samples from 36% and 46%. salinity showed a high density of chloride cells on the epithelia of filaments, and a few cells on the lamellae. Na+, K+-ATPase intensity did not change significantly with an increase in salinity from 36% to 46% but it was significantly higher [p > 0.05] in the FW compared to 12% salinity. There was no significant difference between gill Na+, K+-ATPase activity in FW and 12% salinity, but it was significantly higher [p > 0.05] in the fish acclimated to 36' and 46% salinity [3.3- and 5.1-fold] compared to 12%. The capability of L. aurata fry to change the number and size of gill chloride cells, as well as their activities indicate the high degree of adaptability of this fish to a wide range of salinity
