Telephone follow-up based on empowerment theory to improve resilience and quality of life among patients after coronary artery stent implantation: a randomized controlled trial.

Background: Coronary heart disease has a high incidence rate, a high mortality rate, a high recurrence rate, and a high medical cost. In addition, some patients need to undergo percutaneous coronary artery stent implantation (CASI), which is a kind of traumatic treatment. Patients can easily experience negative emotions such as anxiety and depression after surgery, which seriously affects quality of life. Objectives: The aim of this study was to evaluate the effectiveness of an empowerment-based telephone follow-up intervention on resilience and quality of life in patients who underwent CASI. Design: The design of the study is a randomized controlled trial. Methods: A total of 92 patients were recruited after CASI from the Internal Medicine Cardiovascular Department of a Grade A tertiary hospital in Xi'an, China. The patients were randomly divided into a control group and an intervention group. The control group performed routine care, whereas the intervention group developed a telephone follow-up program based on empowerment theory while carrying out routine care. Patients were investigated using the coronary heart disease-related knowledge questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), and the 36-Item Short-Form Health Survey (SF-36) to compare the effects of the intervention before and after 1 month of intervention. Results: After a 1-month telephone follow-up intervention based on the empowerment theory for patients after CASI, the variations in knowledge related to coronary heart disease and all of its subscale scores were greater in the intervention group than in the control group. Except for the three dimensions of risk factor, induction factor, and rehabilitation-related knowledge, the variations in knowledge related to coronary heart disease and the other subscale scores were significantly different between the two groups (p < 0.05). The variations in resilience and scores on the three subscales in the intervention group were greater than those in the control group, and the difference between the two groups was statistically significant (p < 0.05). The variations in the quality of life and overall health, emotional functions, and social functions were significantly greater in the intervention group than in the control group (p < 0.05). Conclusions: A telephone follow-up intervention based on the empowerment theory can effectively improve the resilience and quality of life of patients after CASI. This follow-up approach can provide a theoretical basis and practical reference for hospitals and communities to carry out targeted continuing nursing for patients after CASI. The long-term effects of the intervention and its underlying mechanisms require further study.

Effects of a temporal self-regulation theory-based intervention on self-management in hemodialysis patients: A randomized controlled trial.

OBJECTIVE: To investigate the effects of a temporal self-regulation theory-based intervention on self-management in hemodialysis patients. METHODS: A randomized controlled trial was carried out in Lanzhou, China. Participants were randomly allocated to either the intervention group (n = 42) or control group (n = 42). The outcomes of self-management level, interdialytic weight gain, serum potassium and serum phosphorus were collected at baseline (T0), 1 month after intervention (T1), and 2 months after follow-up (T2). RESULTS: After intervention and follow-up, the self-management score of the intervention group was significantly higher than that of the control group, while the interdialytic weight gain, serum potassium, and serum phosphorus were significantly lower. The group and time interaction effects revealed that participants in the intervention group exhibited significantly greater improvement in self-management at T1 and T2. Interdialytic weight gain decreased significantly at T2. Serum potassium levels did not differ significantly at T1 or T2. The changes in serum phosphorus were both significant at T1 and T2. CONCLUSION: This study demonstrated that the temporal self-regulation theory-based intervention was effective in improving hemodialysis patients' self-management. PRACTICE IMPLICATIONS: The findings suggest popularizing and applying this intervention in the clinic to maintain the long-term effectiveness of the intervention effect.

7295 elderly hospitalized patients with catheter-associated urinary tract infection: a case-control study.

BACKGROUND: Catheter-associated urinary tract infection (CAUTI) ranks second among nosocomial infections in elderly patients after lung infections. Improper treatment can lead to death. This study analysed the risk factors, pathogen distribution, clinical characteristics and outcomes of CAUTI in elderly inpatients with a large sample size to provide evidence for clinical prevention and control. METHODS: Based on the HIS and LIS, a case‒control study was conducted on all hospitalized patients with indwelling urinary catheters ≥ 60 years old from January 1, 2019, to December 31, 2022, and the patients were divided into the CAUTI group and the non-CAUTI group. RESULTS: CAUTI occurred in 182 of 7295 patients, and the infection rate was 3.4/per 1000 catheter days. Urine pH ≥ 6.5, moderate dependence or severe dependence in the classification of self-care ability, age ≥ 74 years, male sex, hospitalization ≥ 14 days, indwelling urinary catheter ≥ 10 days, diabetes and malnutrition were independent risk factors for CAUTI (P < 0.05). A total of 276 strains of pathogenic bacteria were detected in urine samples of 182 CAUTI patients at different times during hospitalization. The main pathogens were gram-negative bacteria (n = 132, 47.83%), followed by gram-positive bacteria (n = 91, 32.97%) and fungi (n = 53, 19.20%). Fever, abnormal procalcitonin, positive urinary nitrite and abnormal urination function were the clinical characteristics of elderly CAUTI patients (P < 0.001). Once CAUTI occurred in elderly patients, the hospitalization days were increased by 18 days, the total hospitalization cost increased by ¥18,000, and discharge all-cause mortality increased by 2.314 times (P<0.001). CONCLUSION: The situation of CAUTI in the elderly is not optimistic, it is easy to have a one-person multi-pathogen infection, and the proportion of fungi infection is not low. Urine pH ≥ 6.5, moderate or severe dependence on others and malnutrition were rare risk factors for elderly CAUTI in previous studies. Our study analysed the clinical characteristics of CAUTI in the elderly through a large sample size, which provided a reliable basis for its diagnosis and identified the adverse outcome of CAUTI.

Perceived stress, social support, and insomnia in hemodialysis patients and their family caregivers: an actor-partner interdependence mediation model analysis.

Objectives: Patients' and caregivers' physical and mental health may interact. The theory of dyadic illness management holds that patients and caregivers should be regarded as a whole in health management. Previous studies have found that hemodialysis patients and their family caregivers experience poor sleep quality. Perceived stress and social support have effects on insomnia. However, the dyadic interaction between perceived stress, social support, and insomnia among hemodialysis patients and caregivers is unclear. This study aimed to explore the mediating role of social support in the association between perceived stress and insomnia in hemodialysis patient-caregiver dyads. Methods: A total of 259 hemodialysis patient-caregiver dyads completed the Chinese Perceived Stress Scales (CPSS), the Perceived Social Support Scale (PSSS), and the Athens Insomnia Scale (AIS) in Lanzhou, China, from May 2022 to July 2022. The actor-partner interdependence mediation model analysis was used for data analysis. Results: In the actor effect, there was a significant positive correlation between perceived stress and insomnia in hemodialysis patients (ß = 0.091, p = 0.001) and their family caregivers (ß = 0.588, p < 0.001). Patient's and caregiver's social support played partial mediating roles in the relationship between caregiver's perceived stress and insomnia (ß = 0.135, p < 0.001 and ß = 0.111, p < 0.001). In the partner effect, caregiver's perceived stress was positively connected with patient's insomnia (ß = 0.915, p < 0.001), and the mediating effect of patient's social support on the relationship between caregiver's perceived stress and patient's insomnia was statistically significant (ß = -0.040, p = 0.046). Conclusion: The perceived stress, social support and insomnia of hemodialysis patients and their family caregivers had interactive effects. Effective dyadic-based interventions should be developed to improve hemodialysis patients' and caregivers' sleep quality.

Soft drinks, tea and coffee consumption in relation to risk of fracture: evidence from china health and nutrition survey.

INTRODUCTION: To investigate the association between soft drinks, tea and coffee consumption, and risk of fracture in the China Health and Nutrition Survey. MATERIALS AND METHODS: A cross-sectional study with multi-stage random cluster sampling was conducted in nine Chinese provinces in 2004, 2006, 2009 and 2011. A total of 36,740 participants were included the data analyses. Self-administered questionnaires and physical examinations provided data on beverages consumption, fracture history, and other potential risk factors. Binary logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for potentially confounding variables. RESULTS: The prevalence of fracture increased over the 7-year period of the surveys, with 1833 (5.3%) participants reporting a fracture history. Soft drink consumption increased over this time period, and tea consumption was relatively stable, whereas coffee consumption tended to increase sharply. Consumers of soft drinks ≥ 3 times/week (versus never) had a higher risk of fracture (OR = 1.86, 95% CI = 1.43-2.32, p < 0.001, p for trend = 0.039). Consumers of tea ≥ 5 cups/day (versus never) also had a higher risk of fracture (OR = 1.21, 95% CI = 1.09-1.45, p = 0.028, p for trend < 0.001). Similarly, consumers of coffee ≥ 2 cups/day (versus never) had a higher risk of fracture (OR = 1.84, 95% CI = 1.01-3.34, p = 0.045, p for trend = 0.002). Subgroup analyses by gender suggested that coffee consumption increased risk of fracture in females (OR = 1.84, 95% CI = 1.32-2.63, p = 0.001). CONCLUSION: Our findings suggest that high consumption of soft drinks, tea and coffee is associated with an increased risk of fracture in the Chinese population. Which has important public health implications given the widespread consumption of these beverages.

Applying self-determination theory towards motivational factors of physical activity in people undergoing haemodialyses: A qualitative interview study.

INTRODUCTION: The level of physical activity of people undergoing haemodialyses is low, so understanding what factors underlie the motivation to be physically active in people undergoing haemodialyses is important. Therefore, this qualitative study aims to explore the different motivation types and corresponding basic psychological needs (BPNs) of people undergoing haemodialyses based on self-determination theory. METHODS: We adopted the objective sampling method to select 19 patients with the end-stage renal disease aged from 28 to 66 years old from a tertiary hospital in Xi'an. They underwent haemodialyses five to six times every 2 weeks for more than 3 months. Then, we conducted semistructured one-on-one interviews with 19 people undergoing haemodialyses using qualitative content analysis. All interviews were recorded, transcribed verbatim and analyzed on a thematic analysis. RESULTS: We analyzed four motivation types of patients, namely four themes, including entrenching in physical inactivity (Amotivation), breaking physical inactivity (Controlled motivation), finding one's way (Autonomous regulation) and enjoying the positive effects of physical activity (Intrinsic motivation). Each motivation is dominated by one or more BPNs. For example, inadequate Competence such as decreased physical function is the reason why the patient does not perform physical activities. Due to the lack of health education on physical activity, people undergoing haemodialyses often lack the motivation for controlled regulation. The motivation for self-regulation is generated by the patients' promotion of meeting BPNs, such as normal social interactions. The formation of patients' autonomous motivation can't be separated from the effective understanding felt by other patients, because their situations are similar. Enjoying physical activity promotes the formation of patients' intrinsic motivation and the maintenance of this behaviour. CONCLUSION: Perceived Competence, Relatedness and Autonomous Motivation are important determinants for physical activity in people undergoing haemodialyses. Patients need to internalize the changed values and skills, so as to generate the motivation of self-regulation, rather than external or controlled forms of motivation regulation, to better maintain behaviour change. PATIENT OR PUBLIC CONTRIBUTION: People undergoing haemodialyses were involved in the development of the interview topic guide to ensure all relevant topics were explored.

The relationship between psychosocial job stressors and insomnia: The mediating role of psychological capital.

AIM: This study aimed to examine the association of job-related stressors and insomnia; to determine the association of psychological capital and insomnia; and to explore whether psychological capital mediates the association between job-related stressors and insomnia among Chinese nurses. DESIGN: A cross-sectional questionnaire survey. METHODS: The STROBE statement was utilized to guide the study. A total of 810 nurses from one tertiary grade hospital in Shan Dong Province, China, were recruited for the present study and a total of 658 valid questionnaires were obtained (effective recovery rate: 81.2%). The study survey consisted of demographic variables, psychological capital, job stress and insomnia. Descriptive analysis, independent-samples T-test, one-way analysis of variance, stratified regression analysis, Pearson correlation analyses, ordinary least-squares regression and the bootstrap method were used to analyse data. RESULTS: Findings of the study determined that demographic, work-related, behavioural and work setting (i.e. working hours, chronic disease, negative life events, smoking behaviour and night shift) factors were differentially associated with experiences of insomnia. The empirical study showed that psychological capital had statistically significant mediating effects between job stressors and insomnia. PUBLIC CONTRIBUTION: This study explored the factors associated with nurses' psychological job stressors and insomnia. Some of the associated factors could be used for the prevention and mitigation of psychosocial dysfunction among nurses. This study found nurses in surgery, emergency department, ICU, working >40 h a week, with chronic illness, experiencing negative life events, shift work and high effort, high overcommitment and low reward had higher scores of insomnia respectively. The results of this study also showed that reward was correlated with the increase of psychological capital, and the increase of psychological capital was correlated with the decrease of insomnia in nurses. On the contrary, effort and overcommitment decreased psychological capital, and then increased insomnia among nurses. These findings have important implications for future research and policy interventions to improve sleep quality of nurses and enhance nurses' health and patients' safety. This study significantly suggests that improving nurses' psychological capital is a potential way to help nurses improve sleep quality when psychosocial job stressors are difficult external environment to change.

Self-management experiences of haemodialysis patients with self-regulatory fatigue: A phenomenological study.

AIM: To understand the real experiences of self-management in haemodialysis patients with self-regulatory fatigue, and to explore the influencing factors and coping strategies for patients with decreased self-management. DESIGN: A qualitative study was carried out using the phenomenological analysis method. METHODS: From 5 January to 25 February, 2022, semi-structured interviews were conducted with 18 haemodialysis patients in Lanzhou, China. Thematic analysis of the data was performed using the NVivo 12 software based on the 7 steps of Colaizzi's method. The study reporting followed the SRQR checklist. RESULTS: Five themes and 13 sub-themes were identified. The main themes were difficulties in fluid restrictions and emotional management, hard to adhere to long-term self-management, uncertainty about self-management, influencing factors are complex and diverse and coping strategies should be further improved. CONCLUSION: This study revealed the difficulties, uncertainty, influencing facts and coping strategies of self-management among haemodialysis patients with self-regulatory fatigue. A targeted program should be developed and implemented according to the characteristics of patients to reduce the level of self-regulatory fatigue and improve self-management. IMPACT: Self-regulatory fatigue has a significant impact on the self-management behaviour of haemodialysis patients. Understanding the real experiences of self-management in haemodialysis patients with self-regulatory fatigue enables medical staff to correctly identify the occurrence of self-regulatory fatigue in time and help patients adopt positive coping strategies to keep effective self-management behaviour. PATIENT OR PUBLIC CONTRIBUTION: Haemodialysis patients who met the inclusion criteria were recruited to participate in the study from a blood purification centre in Lanzhou, China.

Impacts of cognition of exercise on physical activity participation in hemodialysis patients.

INTRODUCTION: Physical inactivity is a strong predictor of mortality in hemodialysis patients. Although regular physical activity reduces mortality, patients remain inactive. Comparing the cognition of exercise in hemodialysis patients with different physical activity status could highlight domains where inactive people experience heightened barriers to physical activity. We therefore assessed patients' perceived benefits and barriers to exercise using a standardized way, thereby informing future exercise interventions to address these barriers experienced by inactive patients. METHODS: ESRD patients undergoing hemodialysis were recruited and asked to complete a human activity profile, wear a pedometer for seven consecutive days, and complete the Dialysis Patient-perceived Exercise Benefits and Barriers Scale (DPEBBS). Binominal Logistic regression analysis was conducted to determine which benefits and barriers are associated with physical activity. This cross-sectional observational study was registered as NCT05189795. RESULTS: A total of 505 patients completed the survey, most of whom were male (67.1%), with an average age of 49.69 ± 13.96 years. And 52.67-76.63% patients on HAP questionnaire were inactive. The co-benefits in active patients were improving mood and prevention of muscle wasting but did not reach significance in physical activity level. Tiredness, muscle fatigue, and lack of knowledge of exercise were common barriers to patients, and all have a significant impact on a patient's physical activity level. CONCLUSIONS: For inactive patients, exercise during hemodialysis can not only improve physical activity but also reduce family burden. And improving physical activity is a long-term project that cannot be separated from the support of hemodialysis medical staff.

The effects of exercise training interventions on depression in hemodialysis patients.

Purpose: Depression considerably influences the clinical outcomes, treatment compliance, quality of life, and mortality of hemodialysis patients. Exercise plays a beneficial role in depressive patients, but its quantitative effects remain elusive. This study aimed to summarize the effects of exercise training on depression in patients with end-stage renal disease undergoing hemodialysis. Methods: The PUBMED, EMBASE, and Cochrane Library databases were systematically searched from inception to April 2023 to identify published articles reporting the effect of exercise training on the depression level of patients with End-Stage Renal Disease undergoing hemodialysis. Data were extracted from the included studies using predefined data fields by two independent researchers. The Cochrane Handbook for Systematic Reviews of Interventions and Joanna Briggs Institute Critical Appraisal Checklist for Quasi-Experimental Studies were employed for quality evaluation. Results: A total of 22 studies enrolling 1,059 patients who participated in exercise interventions were included. Hemodialysis patients exhibited superior outcomes with intradialytic exercise (SMD = -0.80, 95% CI: -1.10 to -0.49) and lower levels of depression following aerobic exercise (SMD = -0.93, 95%CI: -1.32 to -0.55) compared to combined exercise (c - 0.85, 95% CI: -1.29 to -0.41) and resistance exercise (SMD = -0.40, 95%CI: -0.96 to 0.17). Regarding exercise duration, patients manifested lower depression levels when engaging in exercise activities for a duration exceeding 6 months (SMD = -0.92, 95% CI: -1.67 to -0.17). Concerning the duration of a single exercise session, the most significant improvement was noted when the exercise duration exceeded 60 min (SMD = -1.47, 95% CI: -1.87 to -1.06). Conclusion: Our study determined that exercise can alleviate depression symptoms in hemodialysis patients. This study established the varying impacts of different exercise parameters on the reduction of depression levels in hemodialysis patients and is anticipated to lay a theoretical reference for clinicians and nurses to devise tailored exercise strategies for interventions in patients with depression. Systematic review registration: https://www.crd.york.ac.uk/prospero/, This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database, with registration number CRD42023434181.

The influence of job burnout on the attention ability of army soldiers and officers: Evidence from ERP.

Job burnout is one of the most widespread mental problems in today's society and seriously affects the mental health and combat effectiveness of soldiers and officers. Herein, the effect of burnout on individual attention is studied from the perspective of neuroelectrophysiology. A total of 1,155 army soldiers and officers were included in this investigation and completed the Job Burnout Scale for Military Personnel. A total of 42 soldiers and officers were randomly selected from those with and without burnout to participate in an event-related potential (ERP) study using a visual oddball task. The characteristics of visual P3a and P3b at Fz, FCz, Cz, CPz, and Pz were recorded and analyzed by repeated-measures analysis of variance (ANOVA). P < 0.05 was the criterion for a significant difference. The total average score on the Job Burnout Scale for Military Personnel among the participants was 0.74 ± 0.46, and the detection rate of job burnout was 29.85%. In the Oddball task, the average number of target stimuli counted in the burnout group was lower than that in the control group, but no significant difference was found. For P3a, the Fz, FCz, Cz, CPz, and Pz amplitudes in the burnout group were significantly lower than those in the control group. The average amplitude of P3a evoked in the central parietal area was larger than that in the prefrontal area. For P3b, the amplitudes of the five electrodes in the burnout group were significantly lower than those in the control group. The average amplitude of P3b evoked in the parietal region was larger than those in the prefrontal and central parietal regions. A certain degree of job burnout is evident in army soldiers and officers. The voluntary attention and involuntary attention of individuals with burnout are both affected to some extent, as reflected by the lower amplitudes of P3a and P3b. The results suggest that P3a and P3b can be used as indicators to monitor cognitive neural function in soldiers and officers with burnout and can also be used as references for evaluating the effects of cognitive training and screening methods. In this study, ERP was used to research the attention ability of soldiers and officers with job burnout, and related issues were discussed from the aspects of the burnout results, behavioral results, ERP results, compensation effect of cognitive resources, application in the military field, limitations, and prospects.

Occupational Stress and Insomnia Symptoms Among Nurses During the Outbreak of COVID-19 in China: The Chain Mediating Effect of Perceived Organizational Support and Psychological Capital.

Background: Nurses play an important role in medical and health services and insomnia symptoms were relatively high among nurses, especially during the epidemic of 2019 coronavirus disease. Insomnia not only damages the physical and mental health of the individual, but also reduces the efficiency of their work and the quality of care, ultimately impacting on patient care. Objective: The purpose of this study was to explore the role of perceived organizational support and psychological capital in the relationship between occupational stress and insomnia among Chinese nurses. Methods: A cross-sectional study has been carried out in a tertiary grade A hospital in Shandong Province, China from March 2021 to May 2021. The self-administered questionnaires were distributed to 810 nurses, which including Chinese Effort-Reward Imbalance Scale, Athens Insomnia Scale, Perceived Organizational Support Questionnaire, Chinese Psychological Capital Questionnaire, gender, age, education level and other demographic characteristics. Effective respondents were 658 (81.2%). Descriptive analysis, independent-samples t-test, one-way analysis of variance, Pearson correlation analyses, ordinary least-squares regression and the bootstrap method were used for data analysis. Results: The prevalence of insomnia symptoms in this study was found to be 57.3%. There were significant differences in insomnia symptoms in weekly working hours (t = -2.027, P = 0.043), with chronic disease (t = -2.825, P = 0.005), negative life events (t = -5.340, P < 0.001), departments (F = 3.077, P = 0.006) and position (t = 2.322, P = 0.021) among nurses. Overall, the serial-multiple mediations of perceived organizational support and psychological capital in the relationship between occupational stress and insomnia were found to be statistically significant. Conclusions: The prevalence of insomnia symptoms was comparatively high among Chinese nurses, and occupational stress had direct negative influence on it. Perceived organizational support and psychological capital acted as chained mediating factor could partially relieve insomnia symptoms related to occupational stress. Supportive working environment should be provided, and improving psychological capital levels to help nurses coping with insomnia symptoms.

Incidence and Risk Factors of Lower-Extremity Deep Vein Thrombosis After Thrombolysis Among Patients with Acute Ischemic Stroke.

BACKGROUND: Deep vein thrombosis (DVT) is common among patients with stroke. However, the incidence of DVT in acute ischemic stroke patients treated with thrombolytic therapy and the risk factors associated with this condition are unknown. OBJECTIVE: This study aimed to investigate the incidence and risk factors of DVT after thrombolysis in patients with acute ischemic stroke. SETTINGS AND METHODS: We retrospectively reviewed the medical records of all patients with acute ischemic stroke who underwent ultrasonic examination after intravenous thrombolysis between April 2017 and December 2019 at the stroke center of the First Hospital of Jilin University, China. Color duplex ultrasound was used to diagnosis DVT in all patients within 72 h after intravenous thrombolysis. Univariate and multivariate logistic regression analyses were performed to identify the risk factors for DVT. RESULTS: Overall, 474 patients were included in the study. Of these, 75 (15.8%) developed DVT (95% confidence interval 12.5-19.1). Older age was the risk factor that most significantly affected the development of DVT (p = 0.001). Compared to patients younger than 60 years old, those aged 60-69 years and ≥70 years had a higher risk of DVT, at rates of 2.201 (95% CI: 1.033-4.689; p < 0.05) and 4.241 (95% CI: 2.016-8.922; p < 0.001) times higher, respectively. Patients with higher triglyceride levels (odds ratio 0.545, 95% CI: 0.372-0.799, p = 0.002) and longer activated partial thromboplastin time (OR 0.927, 95% CI: 0.862-0.996, p = 0.040) were less likely to have DVT. CONCLUSION: DVT is a common complication among patients undergoing intravenous thrombolysis after acute ischemic stroke. Advanced age may increase the occurrence of DVT to some extent. For these patients, safe antiplatelet therapy should be explored and implemented as soon as possible.

Effects of a Goal-Oriented Intervention on Self-Management Behaviors and Self-Perceived Burden After Acute Stroke: A Randomized Controlled Trial.

Background: Stroke generates significant health and social burdens. Self-management has potential importance for supporting individuals in coping and continuing to progress after stroke. However, there is a lack of targeted programs to enhance self-management and reduce self-perceived burden (SPB) following stroke. Purpose: To evaluate the effects of a goal-oriented intervention on self-management behaviors and SPB among patients after acute stroke. Methods: This was a randomized controlled trial with a 4-weeks intervention. Participants were randomly allocated to the intervention (n = 48) or control group (n = 48). The intervention and control groups received eight sessions of goal-oriented self-management intervention based on Pender's health promotion model and control care, respectively. Self-management behaviors and SPB were evaluated and compared between the two groups. Results: After the 1-month follow-up, there were significant differences in the total self-management behaviors score and the scores of six of the self-management dimensions, excluding diet management, between the intervention group and the control group (t = -7.891- -2.815; p ≤ 0.006). Compared to the control group, the intervention group showed a significant decrease in the physical burden, emotional burden, and total SPB scores (t = 2.102-2.071; p = 0.015-0.041). The economic burden score was not significantly different between the two groups (t = 1.707; p = 0.091). Conclusion: The goal-oriented intervention based on Pender's health promotion model can effectively improve self-management behaviors and reduce physical and emotional SPB among stroke survivors.

Effects of an empowerment-based intervention on health-related knowledge and resilience in patients with coronary artery stent implantation.

OBJECTIVES: To examine the effects of an empowerment-based intervention on health-related knowledge and resilience among patients after coronary artery stent implantation. METHODS: This was a randomized controlled trial with a 4-week-long intervention. Participants were randomly allocated to an empowerment-based intervention group (n = 42) or control group (n = 43). Knowledge on CHD and resilience were evaluated and compared between groups. RESULTS: Compared with the control group, patients in the intervention group showed higher score changes for CHD total knowledge (U = 196.500; P ＜ 0.001) and its 5 dimensions including CHD definition (U = 657.500; P = 0.022), manifestation (U = 245.000; P ＜ 0.001), examination (U = 639.000; P = 0.015), treatment (U = 475.000; P ＜ 0.001), and medication (U = 465.000; P ＜ 0.001), and higher level of resilience (t = 3.235; P = 0.002). CONCLUSION: The empowerment-based intervention was effective in enhancing the knowledge on CHD and improving resilience for patients with coronary artery stent implantation. PRACTICE IMPLICATIONS: The structured empowerment-based intervention provides a basis for facilitating the use of this intervention in patients with coronary heart disease.

Vitamin K2 Alleviates Insulin Resistance in Skeletal Muscle by Improving Mitochondrial Function Via SIRT1 Signaling.

Aims: High-fat diet (HFD)-induced insulin resistance (IR) impairs skeletal muscle mitochondrial biogenesis and functions, adversely affecting human health and lifespan. Vitamin K2 (VK2) has a beneficial role in improving insulin sensitivity and glucose metabolism. However, the underlying molecular mechanisms of VK2 on insulin sensitivity have not been well established. We investigated VK2's modulation of mitochondrial function to protect against IR in mice and cell models. Results: VK2 supplementation could effectively ameliorate the development of IR by improving mitochondrial function in both HFD-fed mice and palmitate acid-exposed cells. We revealed for the first time that HFD-caused mitochondrial dysfunction could be reversed by VK2 treatment. VK2 enhanced the mitochondrial function by improving mitochondrial respiratory capacity, increasing mitochondrial biogenesis and the enzymatic activities of mitochondrial complexes through SIRT1 signaling. The benefits of VK2 were abrogated in C2C12 transfected with SIRT1 siRNA but not in C2C12 transfected with AMPK siRNA. VK2 and SRT1720, a specific agonist of SIRT1, had the same effect on improving mitochondrial function via SIRT1 signaling. Thus, SIRT1 is required for VK2 improvement in skeletal muscle. Further, the beneficial effects of both VK2 and geranylgeraniol contribute to inhibited IR in skeletal muscle via SIRT1. Innovation and Conclusion: These studies demonstrated a previously undiscovered mechanism by which VK2 alleviates IR in skeletal muscle by improving mitochondrial function via SIRT1. Naturally occurring VK2 prevents IR by improving mitochondrial function through SIRT1 signaling. These results could provide a foundation to identify new VK2-based preventive and therapeutic strategies for IR.

Correlation between self-perceived burden and self-management behavior in elderly stroke survivors: A longitudinal observational study.

The aim of this study was to assess the levels of self-perceived burden (SPB) and self-management behavior in elderly stroke survivors during the first 3 months after acute stroke, and to explore the correlation between them.A total of 203 consecutive hospitalized elderly patients diagnosed with stroke were recruited. Self-perceived Burden Scale and Stroke Self-management Scale in 1 month (T1) and 3 months (T2) post-stroke were assessed and compared.The score of SPB in elderly stroke survivors was 28.96 ±â€Š5.50 and 27.25 ±â€Š6.17 at T1 and T2, respectively. Stroke self-management scale scored 165.93 ±â€Š9.82 at T1 and 167.29 ±â€Š10.60 at T2. In the first 3 months post-stroke, the physical burden was dominant (T1 14.73 ±â€Š3.07, T2 14.40 ±â€Š3.13), and the behavior of stroke symptoms and signs monitoring (T1 27.58 ±â€Š6.56, T2 28.64 ±â€Š6.43) and rehabilitation exercise management (T1 21.40 ±â€Š3.28, T2 20.74 ±â€Š3.15) was the worst. SPB was negatively correlated with self-management behavior (T1 r = -.202, T2 r = -.511).Elderly stroke survivors experienced a medium level of SPB and self-management behavior in the first 3 months post-stroke. There is a positive relationship between reduced SPB and improved self-management behavior. Addressing the characteristics and correlations as well as development of targeted interventions for SPB decreasing is beneficial to improving self-management behavior for elderly survivors.

SLC6A4 gene L/S polymorphism and susceptibility to pulmonary arterial hypertension: a meta-analysis.

OBJECTIVE: To investigate the association between the solute carrier family 6 member 4 (SLC6A4) gene L/S polymorphism and pulmonary arterial hypertension (PAH). METHODS: The relevant literature was retrieved from the PubMed® database and the data were extracted. STATA® version 12.0 software was used to calculate pooled odds ratios (ORs) and 95% confidence intervals (CI). RESULTS: Eight case-control studies qualified for inclusion in the meta-analysis. These studies included 1215 cases and 936 control subjects. There was no significant association between the SLC6A4 gene L/S polymorphism and PAH risk in the total population (LL versus SS: OR 1.83, 95% CI 0.95, 3.51; LS versus SS: OR 1.37, 95% CI 0.93, 2.02; dominant model: OR 1.38, 95% CI 0.97, 1.97; recessive model: OR 1.54, 95% CI 0.84, 2.83). Subgroup analysis based on study quality scores and Hardy-Weinberg equilibrium also showed no significant association. CONCLUSION: The findings of this meta-analysis suggest that the SLC6A4 gene L/S polymorphism is unlikely to be related to PAH risk. Well-designed studies with more participants will be required to validate these results.

Predictors and Changes of Self-Perceived Burden Among Stroke Survivors: A 3-Month Follow-Up Study.

Background and Purpose: Patients' self-perceived burden (SPB) is associated with distress, which has a potentially negative influence on disease rehabilitation and quality of life. Stroke represents a significant health and social burden. The aim of the study was to assess, compare, and identify predictors of SPB in stroke survivors during the first 3 months post-stroke. Methods: A prospective longitudinal study was used. Consecutive stroke inpatients were recruited from the neurology department of three general hospitals in Xi'an, China. Patients were surveyed using the Self-perceived Burden Scale (SPBS) on the fourth day of admission (Acute phase, Time 1, T1) and 1 month (Time 2, T2) and 3 months (Time 3, T3) post-stroke. Results: Considerable burden was experienced by 84.15-91.50% of patients in the first 3 months post-stroke. The mean score of physical burden was the highest. Over time, physical, emotional, and economic burden all declined. The following characteristics had significant association with increased patient SPB at T1, T2, and T3: age, self-evaluated economic pressure, comorbidity, and functional status (P < 0.01). Patients' knowledge about stroke was only significantly associated with SPB at T3 (P < 0.01). Conclusions: Patients experienced a high degree of SPB in the early stage after stroke. Addressing the characteristics and predicting factors as well as the development of a targeted intervention for SPB may improve survival and post-stroke disability.
