The mediating effect of self-efficacy in the relationship between mental health and quality of life in patients with hypertensive nephrology.

AIMS: To examine the factors associated with the quality of life and the mediating effect of self-efficacy in the relationship between mental health and quality of life among patients with hypertensive nephrology. DESIGN: A cross-sectional and correlational study using the Strengthening the Reporting of Observational Studies in Epidemiology checklist guidelines. METHODS: A total of 202 participants were collected from November 2019 to September 2020 from the outpatient department of nephrology of a regional teaching hospital in Taiwan using a convenience sampling method. The research tools included the World Health Organization-5 Well-Being Index, the Chronic Kidney Disease Self-Efficacy Instrument and the Medical Outcome Study Short Form-12. The mediating effect was statistically analysed by linear regression models and verified by Sobel testing. RESULTS: Mental health and self-efficacy were positively correlated with the overall quality of life. The results showed that the total explanatory variation of mental health and self-efficacy on the overall quality of life was 37.1%. Mental health was the most important explanatory factor, which could explain 27.1% of the variations in the overall quality of life alone. Moreover, self-efficacy was a partial mediator in the relationship between mental health and the quality of life among patients with hypertensive nephrology, with a total effect of 34.8%. CONCLUSIONS: The quality of life of this population can be improved by enhancing mental health, leading to an improvement in self-efficacy. Consequently, improved mental health and self-efficacy will improve the overall quality of life. IMPACT: Medical staff should be able to assess patients' mental health in providing referrals and assistance in a timely manner. If intervention programmes can be developed to improve patients' self-efficacy, their quality of life can also be improved.

Disease Knowledge, Self-Efficacy, and Quality of Life in Patient With Hypertensive Nephropathy.

The purpose of this study is to investigate the relationships among disease knowledge, self-efficacy, and quality of life in patients with hypertensive nephropathy. A cross-sectional and correlational design is employed in this study, and a total of 213 participants are collected by convenience sampling from the outpatient Department of Nephrology of a regional teaching hospital in Taiwan. The research instruments include the Hypertensive Nephropathy Knowledge Instrument, the Chronic Kidney Disease Self-Efficacy Instrument, and the Medical Outcome Study Short Form-12, and stepwise multiple regression analysis is used to test the explanatory power of each significantly-correlated independent variable regarding the quality of life. The results show that the higher the disease knowledge, the better the self-efficacy, and the better the quality of life, and self-efficacy is the most important predictor of the quality of life.

Effect of Patient-Centered Self-Management Program on Blood Pressure, Renal Function Control, and the Quality of Life of Patients With Hypertensive Nephropathy: A Longitudinal Randomized Controlled Trial.

This longitudinal study with a randomized controlled trial evaluated the long-term effectiveness of the patient-centered self-management intervention program on the control of blood pressure and renal function, as well as the quality of life of patients with hypertensive nephropathy. The control group (n = 38) received usual care while the experimental group (n = 38) participated in a patient-centered self-management program. After the pre-test, the intervention was performed with the experimental group once a week for a total of 4 weeks. Then, the post-test was performed 1, 3, and 6 months later. A questionnaire was used to collect the demographic data and disease characteristics, laboratory data, and quality of life scale. This study tracked three time points (i.e., 1, 3, and 6 months) after the intervention and found that the experimental group achieved significant results in controlling systolic blood pressure (p < 0.001), diastolic blood pressure (p = 0.007), and eGFR (p = 0.013). Significant results were achieved in the overall quality of life (p < 0.001) and the quality of life in the physical (PHC; p < 0.001) and mental health components (MHC; p < 0.001). Furthermore, the effects in the experimental group lasted for as long as 6 months and were better than those in the control group. Moreover, this program can provide nursing staff with a reference different from traditional health education methods.

Effect of patient-centred self-management programme on mental health, self-efficacy and self-management of patients with hypertensive nephropathy: A randomised controlled trial.

AIM AND OBJECTIVES: To evaluate the effect of patient-centred self-management programme on mental health, self-efficacy and self-management of patients with hypertensive nephropathy. BACKGROUND: If the symptoms of hypertension are not well-controlled, deterioration of renal function will accelerate and evolve into hypertensive nephropathy. DESIGN: A randomised single-blind trial. This article follows the requirements of CONSORT statement. METHODS: The experimental group (n = 35) after pre-test used patient-centred self-management programme once a week for a total of 4 weeks and the intervention effect was measured after 3 months for post-test. Contrarily, the traditional care was employed for the control group (n = 35). The measuring outcomes included mental health, self-efficacy and self-management. Trial registry is listed under https://clinicaltrials.gov/ with Identifier No. NCT04633993. RESULTS: After the intervention, the average score of mental health for the experimental group was 20.79 (SD = 0.82) which was higher than the 19.27 points for the control group (SD = 0.77) and showed a significant difference (F = 8.31, p = .005, partial eta2  = 0.133). In terms of self-efficacy, the average score for the experimental group was 214.13 (SD = 6.40), which was higher than the 189.58 points for the control group (SD = 6.03) and exhibited a significant difference (F = 11.82, p = .001, partial eta2  = 0.197). Regarding self-management, the average score of the experimental group was 75.12 (SD = 2.29) which was significantly higher than the 68.80 points of the control group (SD = 2.43) (F = 11.17, p = .001, partial eta2  = 0.190). CONCLUSIONS: In addition to promoting mental health of individual cases, this intervention also increases their self-confidence in disease control and improves their self-management on diseases. RELEVANCE TO CLINICAL PRACTICE: The intervention provides an effective option for clinical care workers as a replacement for or supplement to the traditional care.

Heat shock pretreatment attenuates sepsis-associated encephalopathy in LPS-induced septic rats.

Sepsis is the most common cause of mortality in intensive care units. Although sepsis-associated encephalopathy (SAE) is reported to be a leading manifestation of sepsis, its pathogenesis remains unclear. In our previous studies, we showed that heat shock pretreatment can reduce mortality in polymicrobial septic rats and protect the cerebral cortical function during hypoxia or drug-induced convulsion. In the present study, we investigated to what extent heat shock pretreatment might affect the development of SAE in septic rats and the possible mechanism behind its effect was discussed. To do this, we used lipopolysaccharide (LPS) to induce septic response in a SAE animal model. Heat shock pretreatment was performed and rectal temperature maintained between 41 and 42 degrees C for 15 min using an electric heating pad. Electroencephalography (EEG) activity, a sensitive electrophysiological recording of electrical activity in the brain, was used as an indicator of cerebral cortical dysfunction in SAE. In LPS rats not pretreated with heat shock, the EEG background activity decreased 10 min after intraperitoneal administration of LPS. However, in rats pretreated with heat shock, this decrease was significantly attenuated. Untreated septic rats were also found to have earlier, more frequent epileptic spikes. In summary, we found that heat shock could attenuate the electro-cortical dysfunction in rats with LPS-induced septic response, suggesting that heat shock response might potentially be used to prevent SAE in sepsis.
