Effects of a collaborative health management model on people with congestive heart failure: A systematic review and meta-analysis.

AIM: To determine the effects of collaborative health management of congestive heart failure through the rigorous evaluation and extraction of evidence. BACKGROUND: Over the past two decades, cardiovascular disease has been the leading cause of death worldwide. Multidisciplinary team intervention for congestive heart failure has increased with population ageing and congestive heart failure incidence rate as well as cost of care. However, the effectiveness and feasibility of collaborative health management need to be explored. DESIGN: Systematic review and meta-analysis. METHODS: We conducted systematic literature searches in the Cochrane Library, PubMed, CINAHL and Medline for articles published between 2002 and 2022. After screening based on the inclusion and exclusion criteria, 13 articles were included in a rigorous review and evidence extraction process, evaluated methodological quality using the Jadad Quality Scale. Statistical heterogeneity was evaluated using Review Manager (RevMan Version 5.4) for the meta-analysis. RESULTS: In this study, a systematic review and meta-analysis were performed on 13 studies regarding the collaborative health management of people with congestive heart failure. The common result is that the collaborative health management model enables the enhancement of self-care and monitoring abilities, the strengthening of cardiac function, the alleviation of physiological and psychological symptoms and the improvement of readmission rates, mortality rate and quality of life. CONCLUSION: The congestive heart failure collaborative health management model could decrease the hospitalization rate related to congestive heart failure, all-cause mortality rate, and all-cause hospitalization rate, and improve the quality of life. IMPLICATIONS FOR PRACTICE: The collaborative health management model could effectively coordinate interdisciplinary team cooperation and provide information, which decreases hospitalization and mortality risks and improves their quality of life. NO PATIENT OR PUBLIC CONTRIBUTION: Our paper is a systematic review and meta-analysis, and such details do not apply to our work. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: The Collaborative Health Management Model provides in-depth insights, aiding in the design tailored to the specific circumstances of each country. Highlighting its critical role in the context of a global shortage of nursing staff, the model emphasizes the integration of multidisciplinary professional roles and the strengthening of collaboration as essential elements in addressing challenges posed by workforce shortages. Implementation of the Collaborative Health Management Model not only enhances patient care outcomes but also relieves pressure on healthcare systems, lowers medical costs, and addresses challenges arising from the shortage of nursing staff. Consequently, this model not only contributes to individual patient care improvement but also holds broader implications for enhancing the efficiency and sustainability of global healthcare systems.

Predictors of adherence, contamination and dropout in home-based walking by lung and oesophageal cancer patients from two randomised control trials: An exploratory study.

OBJECTIVES: In this study, we examined predictors of exercise adherence, contamination and dropout in lung and oesophageal cancer patients who participated in two randomised controlled trials. METHODS: We used data on 188 lung and oesophageal cancer patients from two previous studies (intervention: moderate-intensity walking for 12 weeks). Baseline measurements included demographic variables, disease characteristics, Hospital Anxiety and Depression Scale and Bouchard 3-day physical activity (PA) record. We used multiple linear and logistic regressions to analyse predictors of exercise adherence in the walking group, contamination in the control group and dropout in both groups. RESULTS: Pre-intervention exercise habits and baseline depression scores predicted adherence, with an explanatory power of 16.7% (p < 0.0001). Pre-intervention exercise habits (odds ratio [OR] 19.65, 95% confidence interval [CI] 2.76-139.97), baseline moderate PA (min/day) (OR 1.03, 95% CI 1.01-1.05) and baseline vigorous PA (min/day) (OR 1.09, 95% CI 1.01-1.18) predicted contamination. Baseline mild PA (10 min/day) (OR 0.94, 95% CI 0.89-0.99) predicted dropout. CONCLUSIONS: Pre-intervention exercise habits and baseline depression levels predicted exercise adherence in the walking group. In the control group, pre-intervention exercise habits and baseline moderate and vigorous PA predicted contamination. Baseline mild PA predicted dropout rates in both groups.

Effect of Guided Imagery Meditation During Laparoscopic Cholecystectomy on Reducing Anxiety: A Randomized Controlled Trial.

BACKGROUND: Up to 90% of patients still experience pain after abdominal surgery, which also affects their physical recovery and psychological anxiety. AIM: To evaluate the effects of guided imagery meditation on ameliorating anxiety, improving the quality of sleep, and relieving postoperative pain in patients after laparoscopic cholecystectomy surgery. METHOD: In the general surgical ward of a teaching hospital, patients were randomly assigned to usual care (n = 34) and guided imagery meditation intervention (n = 34) groups, using the method. The measuring outcomes included their anxiety score, quality of sleep, and pain control. RESULTS: In terms of the anxiety difference, the experimental group scored 0.42 (standard deviation [SD] = 0.97), while the control group scored 4.79 (SD = 7.56), which indicates a statistically significant difference (F = 8.04, p = .01, partial eta2 = 0.11). In terms of quality of sleep, the mean score of the experimental group was 2.67 (SD = 1.96), while the control group scored 7.55 (SD = 3.81), which indicates a significant difference (F = 39.99, p = .001, partial eta2 = 0.39). The mean of the degree of postoperative pain was 2.11 points (SD = 1.39), and the score of the control group was 4.00 points (SD = 1.62), which indicates a significant difference (p = .001). CONCLUSIONS: Guided imagery meditation is a simple, non-invasive, non-pharmacologic intervention measure. It can reduce anxiety and postoperative pain, and improve the quality of sleep. Thus, it should be promoted in clinical practice.

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.

Differences in self-care knowledge, self-efficacy, psychological distress and self-management between patients with early- and end-stage chronic kidney disease.

AIMS: The study compares the differences in self-care knowledge, self-efficacy, psychological distress and self-management between patients with early- and end-stage chronic kidney disease (CKD), and predicts the influential factors of self-management. DESIGN: A cross-sectional study. METHODS: A total of 185 subjects by using convenience sampling from one teaching hospital were collected. The research instruments included the Chronic Kidney Disease Self-Care Instrument Knowledge, the Chronic Kidney Disease Self-Efficacy Instrument, the Hospital Anxiety and Depression Scale, and the Chronic Kidney Disease Self-Management Instrument. Descriptive statistics is used frequency, percentage, mean and standard deviation. Inferential statistics is used independent t-test, one-way ANOVA and multiple linear regression analysis. STROBE checklist was used as the guideline for this study. RESULTS: Our results showed that a significant difference was found in the age (p = 0.005), systolic pressure (p = .006), self-care knowledge (p = .011) and depression level (p = .003) between patients with early- and end-stage CKD. Furthermore, patients with early-stage CKD have less self-care knowledge and lower depression levels compared with patients with end-stage CKD. However, self-efficacy is the most significant predictor of self-management for patients with early- and end-stage CKD. For patients with early-stage CKD, self-efficacy explained 69.1% of the variation in self-management. CONCLUSION: According to our results, the management of depression in patients with CKD may improve their outcomes. Improving self-care knowledge of patients with end-stage CKD may improve their self-management. Therefore, our findings suggest various interventions with different necessary and prioritised precision care at early- and late-stage of CKD. RELEVANCE TO CLINICAL PRACTICE: Nurses should strive to improve the self-care knowledge of patients with early-stage CKD to delay the progression of the disease to end-stage. Screening for depression among patients with end-stage CKD is relevant, and these patients should be referred to professional counsellors when necessary.

Effectiveness of a self-management program in enhancing quality of life, self-care, and self-efficacy in patients with hemodialysis: A quasi-experimental design.

BACKGROUND: Taiwan has the world's highest prevalence of end-stage kidney disease, as well as the world's third highest incidence. The study investigated the effectiveness of a self-management program for enhancing health-related quality of life, self-care behaviors, and self-efficacy in patients with end-stage kidney disease undergoing hemodialysis. METHODS: This was a quasi-experimental design with convenient sampling, and allocated 32 participants in the control group (conventional program) and 32 participants in the experimental group (self-management program). The self-management program intervention lasted 4 weeks, and a posttest was administered 3 months later. The questionnaire included the 36-Item Short Form Health Survey, a Chronic Kidney Disease Self-Care Instrument, and a Chronic Kidney Disease Self-Efficacy Instrument. RESULTS: Three months after the intervention, the self-management program had improved patients' health-related quality of life in the mental health components (p < .001), but not in the physical health components. The program also promoted patients' self-care behaviors (p < .001) and self-efficacy (p < .05). CONCLUSIONS: This study's findings confirmed that self-management programs should be promoted in clinical practice where they will provide clinical care personnel with an alternative to conventional health education.

The Efficacy of Lactobacillus-Containing Probiotic Supplementation in Hemodialysis Patients: A Randomized, Double-Blind, Placebo-Controlled Trial.

OBJECTIVES: This study was performed to determine the effects of probiotic supplementation on cholesterol-triglyceride ratio, an indirect marker of insulin resistance, protein-bound uremic toxins, biomarkers of inflammation, and microbial translocation in end-stage renal disease patients on hemodialysis. METHODS: Fifty-six patients aged 39-75 years were assigned into two groups to receive either probiotic sachets (n = 28) or a placebo (n = 28) in a randomized double-blinded placebo-controlled clinical trial. The patients in the probiotic group received twice daily sachets that contained a mixture of three viable and freeze-dried strains: Lactococcus lactis subsp. Lactis LL358, Lactobaccillus salivarius LS159, and Lactobaccillus pentosus LPE588 at high dose (100 billion; 1 × 1011 cfu/day) for 6 months. RESULTS: A total of 50 patients were available for final analysis. Probiotic supplementation did not have a significant influence on cholesterol-triglyceride ratio. Probiotic supplementation for 6 months caused a significant decrease in serum levels of indoxyl sulfate. Compared with the placebo, probiotic supplementation did not result in significant changes in hemoglobin levels, blood urea nitrogen, blood glucose, serum p-cresyl sulfate, inflammatory, and microbial translocation markers. No clinically significant changes in body composition were observed between the two groups during the study period. The probiotic supplementation was well tolerated by all subjects with minimal adverse effects during the 6-month-long study. CONCLUSION: Our results suggest that high-dose multistrain lactobaccillus probiotic supplementation over 6 months as a monotherapy did not significantly decrease markers of insulin resistance, cholesterol-triglyceride ratio, and most of the studied markers, with the exception of levels of indoxyl sulfate in patients on HD.

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.

In Vitro Antifungal Susceptibility of Neoscytalidium dimidiatum Clinical Isolates from Malaysia.

Neoscytalidium dimidiatum is an opportunistic fungus causing cutaneous infections mostly, which are difficult to treat due to antifungal resistance. In Malaysia, N. dimidiatum is associated with skin and nail infections, especially in the elderly. These infections may be mistaken for dermatophyte infections due to similar clinical appearance. In this study, Neoscytalidium isolates from cutaneous specimens, identified using morphological and molecular methods (28 Neoscytalidium dimidiatum and 1 Neoscytalidium sp.), were evaluated for susceptibility towards antifungal agents using the CLSI broth microdilution (M38-A2) and Etest methods. Amphotericin B, voriconazole, miconazole and clotrimazole showed high in vitro activity against all isolates with MIC ranging from 0.0313 to 1 µg/mL. Susceptibility towards fluconazole and itraconazole was noted in up to 10% of isolates, while ketoconazole was inactive against all isolates. Clinical breakpoints for antifungal drugs are not yet available for most filamentous fungi, including Neoscytalidium species. However, the results indicate that clinical isolates of N. dimidiatum in Malaysia were sensitive towards miconazole, clotrimazole, voriconazole and amphotericin B, in vitro.

The efficacy of a self-management programme for people with diabetes, after a special training programme for healthcare workers in Taiwan: a quasi-experimental design.

AIMS AND OBJECTIVIES: To analyse the efficacy of improving disease management after implementing a self-management programme for people with type 2 diabetes administered by healthcare workers who have received special training. BACKGROUND: The needs for diabetic care include increased training for healthcare providers to enhance their confidence and skills in managing patients, both physically and mentally. DESIGN: Quasi-experimental design. METHODS: This study recruited participants from outpatient clinics in 10 hospitals in Taiwan. In 2010, purposive sampling was used to recruit 228 participants from two medical centres, five regional hospitals and three district hospitals. Participants were enrolled in a 'diabetes self-management programme' (watching patient videos, reading a diabetes self-care handbook, participating in four consultation courses of diabetes self-efficacy improvement, telephone follow-up and positive reinforcement). Efficacy analysis of post-test diabetes outcome variables of the experimental group was carried out. Sex, age and pretest score were used as the control variables for ancova test. RESULTS: Patients in the experimental group had significant improvement in body mass index (p < 0·01), waistline circumference (p < 0·001), haemoglobin A1C levels (p < 0·001), degrees of anxiety and depression (p < 0·001), self-efficacy (p < 0·001) and levels of self-care (p < 0·001). CONCLUSION: Self-efficacy of people with diabetes can be effectively improved by planned implementation of a 'diabetes self-management programme' by trained healthcare workers. RELEVANCE TO CLINICAL PRACTICE: The diabetes care professionals are provided the self-management programme to strengthen the awareness and importance of self-management in diabetes care.

[The use of systematic review to develop a self-management program for CKD].

BACKGROUND: Chronic kidney disease (CKD) has become a public health issue of international concern due to its high prevalence. The concept of self-management has been comprehensively applied in education programs that address chronic diseases. In recent years, many studies have used self-management programs in CKD interventions and have investigated the pre- and post-intervention physiological and psychological effectiveness of this approach. However, a complete clinical application program in the self-management model has yet to be developed for use in clinical renal care settings. PURPOSE: A systematic review is used to develop a self-management program for CKD. METHOD: Three implementation steps were used in this study. These steps include: (1) A systematic literature search and review using databases including CEPS (Chinese Electronic Periodical Services) of Airiti, National Digital Library of Theses and Dissertations in Taiwan, CINAHL, Pubmed, Medline, Cochrane Library, and Joanna Briggs Institute. A total of 22 studies were identified as valid and submitted to rigorous analysis. Of these, 4 were systematic literature reviews, 10 were randomized experimental studies, and 8 were non-randomized experimental studies. (2) Empirical evidence then was used to draft relevant guidelines on clinical application. (3) Finally, expert panels tested the validity of the draft to ensure the final version was valid for application in practice. RESULTS: This study designed a self-management program for CKD based on the findings of empirical studies. The content of this program included: design principles, categories, elements, and the intervention measures used in the self-management program. This program and then was assessed using the content validity index (CVI) and a four-point Liker's scale. The content validity score was .98. The guideline of self-management program to CKD was thus developed. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: This study developed a self-management program applicable to local care of CKD. It is hoped that the guidelines developed in this study offer a reference for clinical caregivers to improve their healthcare practices.

Differences in the perceptions of self-care, health education barriers and educational needs between diabetes patients and nurses.

This study examined the differing perceptions of diabetic patients and their nurses regarding the completion of self-care activities, barriers to participation in diabetes health education, and diabetic patients' educational needs to promote better health care for patients with diabetes in Taiwan. This study employed a cross-sectional survey. The data were collected during 2009. Questionnaires were developed to collect data on a convenience sample of 312 patients with type 2 diabetes and 202 nurses recruited from diabetes clinics in Taiwan. Perceptions of self-care behavior were statistically significantly different between patients and nurses (t = -5.05, P < 0.000). The patients perceived themselves to be more successful at completing self-care tasks whereas nurses perceived patients to be less successful at completing self-care tasks. Nurses perceived patients to experience greater difficulties in diabetes health education (t = 18.36, P < 0.000). Nurses perceived there to be a greater need for health education as compared with patients (t = 9.03, P < 0.000).

Frailty management in older patients: a best practice implementation project.

INTRODUCTION: Frailty in older adults can lead to a gradual decline in organ function. Without timely diagnosis and intervention, this condition can progress rapidly, increasing the risk of disability and mortality. OBJECTIVES: The aim of this project was to implement evidence-based practices for managing frailty in the medical ward to prevent disability in older patients. METHODS: This project was conceptually informed by the JBI Evidence Implementation Framework. This framework uses an audit and feedback approach and a pre- and post-test design to measure baseline compliance, develop implementation strategies responsive to gaps in compliance, and conduct a final evaluation to measure changes in compliance. JBI PACES and JBI GRiP situational analysis software were used to support data collection and implementation planning. Ten audit criteria were used with a sample of 30 patients in a regional teaching hospital in southern Taiwan. RESULTS: The baseline audit showed poor compliance, with rates below 30% for all ten audit criteria. Through strategies such as professional training and education, the implementation of evidence-based care guidelines, and interdisciplinary consensus-building, the follow-up audit revealed an increase in compliance to over 90% for each audit criterion. CONCLUSIONS: Frailty management strategies based on evidence-based audit criteria were implemented and routinely measured. The most effective strategies for improving compliance included the development of a training course, a digitized assessment tool, team meetings, interdisciplinary collaboration, communication, and consensus-building.

Relationships Among Physical Activity, Daylight Exposure, and Rest-Activity Circadian Rhythm in Patients With Esophageal and Gastric Cancer: An Exploratory Study.

BACKGROUND: Although rest-activity circadian rhythm (RACR) disruption is associated with mortality in patients with cancer, few studies have examined the effect of RACR on patients with esophageal and gastric cancer. OBJECTIVE: The aim of this study was to identify the predictors of RACR. METHODS: This cross-sectional, single-site study included 276 patients with esophageal and gastric cancer recruited from chest-surgery and general-surgery outpatient departments. Actigraphy was used to assess objective physical activity (PA), daylight exposure, and RACR, and 3-day PA was used to indicate the subjective amount of PA. The parameter of objective PA was the up activity mean; the parameter of daylight exposure was >500 lx, and the parameters of RACR were the 24-hour correlation coefficient, in-bed less than out-of-bed dichotomy index, midline estimating statistic of rhythm, and amplitude. The subjective amount of PA was calculated as the sum of mild, moderate, and vigorous PA. RESULTS: The up activity mean predicted 24-hour correlation coefficient. The PA amount and up activity mean predicted in-bed less than out-of-bed dichotomy index. The up activity mean and >500-lx daylight exposure predicted midline estimating statistic of rhythm. Finally, the PA amount and up activity mean predicted the amplitude. CONCLUSIONS: Increased PA and daylight exposure may improve RACR. IMPLICATIONS FOR PRACTICE: Patients with esophageal and gastric cancer should be encouraged to engage in outdoor PA during the daytime as part of their regular lifestyle to maintain a robust circadian rhythm.

The Mediating Role of Psychological Well-Being in the Relationship Between Self-Management and Quality of Life in Patients With Hypertension.

This study applied a cross-sectional design to examine the relationship between self-management, psychological well-being, and quality of life in patients with hypertension and evaluated the mediation effect of psychological well-being on self-management and quality of life. Through purposive sampling, this study enrolled 255 patients with hypertension from the cardiology department of a teaching hospital in Taiwan. Mediation effects were estimated using linear regression and the Sobel test. Age, number of chronic diseases, waist circumference, self-management, and psychological well-being explained 18.7% of the total variance in quality of life. Psychological well-being partially mediated the effects of self-management on quality of life, with a total effect of 19.2%. Psychological well-being is an important factor correlated with self-management and quality of life in patients with hypertension.

Self-efficacy, self-care behavior, anxiety, and depression in Taiwanese with type 2 diabetes: A cross-sectional survey.

The relationships between self-efficacy, self-care behavior, anxiety, and depression for Taiwanese individuals with type 2 diabetes were determined in this study. Depression and anxiety are common symptoms that can contribute toward adverse medical outcomes. A descriptive, cross-sectional, correlational design was used. The sample comprised 201 patients with type 2 diabetes from diabetes outpatient clinics at three teaching hospitals in Taiwan. The results of this study revealed that people with diabetes who had received diabetes health education, regularly made clinical visits, underwent treatment, and did not smoke demonstrated a high self-efficacy score (P < 0.05). Self-efficacy among people with diabetes positively correlated with illness duration (P < 0.05), treatment (P < 0.01), and self-care behavior (P < 0.01). Self-efficacy among people with diabetes negatively correlated with anxiety and depression (P < 0.01). Self-efficacy can be a predictor of anxiety and depression (P < 0.01). This study revealed that enhancing self-efficacy levels might reduce anxiety and depression. Self-efficacy-enhancing programs should be held regularly in clinical practices. Conducting psychological research on diabetes drives policy and healthcare system change.

Self-efficacy, professional commitment, and job satisfaction of diabetic medical care personnel.

The purpose of this study was to investigate the relationships among the self-efficacy, professional commitment, and job satisfaction of diabetic health-care personnel. The research design was cross-sectional. Three teaching hospitals, one from each of northern, middle and southern parts of Taiwan, were selected for data collection and used questionnaires to collect data; 202 participants were recruited. The demographic data for job title and job satisfaction were not significantly different (F = 2.13, P = 0.090). Self-efficacy was significantly positively correlated with professional commitment (r = 0.29, P = 0.000) and with job satisfaction (r = 0.14, P = 0.041). A total of 34.1% of the variance in job satisfaction was explained by age, years of service in the medical or nursing field, the actual number of years caring for patients with diabetes, self-efficacy, and professional commitment. Understanding the self-efficacy and professional commitment of medical and nursing personnel can help increase job satisfaction and improve the quality of medical and nursing care.

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.

The Mediating Role of Psychological Well-Being in the Relationship between Self-Care Knowledge and Disease Self-Management in Patients with Hypertensive Nephropathy.

OBJECTIVE: This study aimed to investigate the correlation between self-care knowledge, psychological well-being, and disease self-management in patients with hypertensive nephropathy, and to assess the effect of psychological well-being as a mediator of self-care knowledge and disease self-management. METHODS: This is a cross-sectional study. The 220 patients with hypertensive nephropathy were recruited from a teaching hospital in Taiwan using purposive sampling. The average age was 70.14 (SD = 11.96) years old. Among them, 128 (58.2%) were male and 92 (41.8%) were female. Instruments included a hypertensive nephropathy self-care knowledge scale, the World Health Organization-5 Well-Being Index, and the chronic kidney disease self-management instrument. The mediating effect was determined with linear regression models and the Sobel test. RESULTS: The total explanatory variation of age, systolic blood pressure, psychological well-being, and self-care knowledge on the disease self-management was 27.7%. Psychological well-being was the most important explanatory factor and alone explains 16%. Psychological well-being was a partial mediator of self-care knowledge and quality of life in patients with hypertensive nephropathy, with a total effect of 23.2%. CONCLUSIONS: This study showed that older patients with hypertensive nephropathy and those with a higher systolic blood pressure had lower levels of disease self-management. The higher the patients' self-care knowledge and psychological well-being, the better their disease self-management.

A Review of the Potential Effects of Melatonin in Compromised Mitochondrial Redox Activities in Elderly Patients With COVID-19.

Melatonin, an endogenous indoleamine, is an antioxidant and anti-inflammatory molecule widely distributed in the body. It efficiently regulates pro-inflammatory and anti-inflammatory cytokines under various pathophysiological conditions. The melatonin rhythm, which is strongly associated with oxidative lesions and mitochondrial dysfunction, is also observed during the biological process of aging. Melatonin levels decline considerably with age and are related to numerous age-related illnesses. The signs of aging, including immune aging, increased basal inflammation, mitochondrial dysfunction, significant telomeric abrasion, and disrupted autophagy, contribute to the increased severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. These characteristics can worsen the pathophysiological response of the elderly to SARS-CoV-2 and pose an additional risk of accelerating biological aging even after recovery. This review explains that the death rate of coronavirus disease (COVID-19) increases with chronic diseases and age, and the decline in melatonin levels, which is closely related to the mitochondrial dysfunction in the patient, affects the virus-related death rate. Further, melatonin can enhance mitochondrial function and limit virus-related diseases. Hence, melatonin supplementation in older people may be beneficial for the treatment of COVID-19.
