Association between medication literacy and medication adherence and the mediating effect of self-efficacy in older people with multimorbidity

BACKGROUND

Multimorbidity has a significant impact on public health and primary care. Medication adherence is recognized as the most effective measure for managing and preventing multimorbidity. Studies have shown that medication literacy has a positive effect on medication adherence in patients with multimorbidity. However, limited knowledge exists regarding the underlying mechanisms of this relationship in older adults with multimorbidity. Therefore, the aim of this study was to investigate the mediating role of self-efficacy in the association between medication literacy and medication adherence in this population.

METHODS

This study employed a cross-sectional design and convenience sampling method to survey older patients with multimorbidity in six communities in Zhengzhou, China, from July 12, 2021, to December 15, 2021. Participants were assessed using a demographic questionnaire, the Chinese Version of the Medication Literacy Scale (C-MLS), the Self-Efficacy for Appropriate Medication Use Scale (SEAMS), and the Chinese Version of the Morisky Medication Adherence Scale-8 (C-MMAS-8). Data were analyzed using descriptive statistics, t-tests, one-way analysis of variance, Pearson correlation analysis, and mediation analysis.

RESULTS

A total of 350 elderly patients met the inclusion criteria, and 328 valid questionnaires were collected. The mean age of the participants was 74.90 ± 7.37 years, with a slightly higher proportion of males (55.8%) than females (44.2%). The mean score for medication adherence was 4.85 ± 1.57, indicating poor medication adherence among the participants. Medication adherence scores varied significantly among participants of different ages, education levels, employment statuses and kinds of medication (p < 0.01). Scores for medication literacy and self-efficacy showed a significant positive correlation with medication adherence scores (all p < 0.001). The standardized coefficient for the total effect and direct effect of medication literacy on medication adherence was 0.268 (95% CI: 0.201, 0.335) and 0.187 (95% CI: 0.123, 0.252), respectively. After introducing self-efficacy into the model, the standardized coefficient for the indirect effect was 0.081 (95% CI: 0.049, 0.120), indicating that self-efficacy partially mediated the relationship between medication literacy and medication adherence, accounting for 30.22% of the total effect.

CONCLUSION

This study might suggest that medication literacy indirectly affected medication adherence in older people with multimorbidity through self-efficacy. Health care providers should be aware of the importance of improving medication literacy and implement strategies aimed at increasing self-efficacy to achieve the goal of improving medication adherence in older adults with multimorbidity.

[Mechanism study of platelet derived growth factor receptor alpha on the bidirectional differentiation regulation of glioma-associated oncogene homolog 1-positive mesenchymal stem cells in mice]

Objective: To investigate the role of platelet derived growth factor receptor alpha (PDGFRα) on bidirectional differentiation of glioma-associated oncogene homolog 1-positive mesenchymal stem cells (Gli1+-MSC). Methods: Breeding double reporter transgenic mice ROSAmT/mG/Gli1-Cre^ERt2/PDGFRα^fl (Experimental group) and ROSA^mT/mG/Gli1-Cre^ERt2 (Control group), 20 mice in each of the two groups at four weeks of age were selected, MSC were isolated from the mouse aortic epithelium. After tamoxifen inducement, the two groups of Gli1⁺-MSC were screened by green fluorescent protein (GFP) labeling and flow cytometry sorting. PDGFRα was conditionally knocked out in the experimental group, and the control group Gli1⁺-MSC expressed PDGFRα normally. The two groups of Gli1⁺-MSC were subjected to adipogenic induction and fibrogenic induction, the Western blotting was performed to detect PDGFRα, adipocyte markers [perilipin and CCAAT/enhancer binding protein alpha (C/EBPα)] and fibrogenic markers [alpha smooth muscle actin (α-SMA) and fibroblast-specific protein 1 (FSP-1)] and semi-quantitative analysis was performed. The degree of cellular adipose differentiation after bidirectional induction of Gli1+-MSC in both groups was observed by oil red O staining and analyzed semi-quantitatively. Results: After tamoxifen induction, Gli1⁺-MSC could be accurately isolated from flow cytometry by GFP labeling. Via adipogenic differentiation, the expression of PDGFRα in the experimental group (0.017±0.002) was significantly lower than that in the control group (0.184±0.012) (t=25.48，P=0.002). The protein expressions of perilipin (3.138±0.414) and C/EBPα (3.565±0.289) were significantly higher than those in the control group (2.312±0.218 and 2.179±0.103, respectively) (t=6.21，P=0.025；t=6.69，P=0.022). Thus, the knock-out of PDGFRα enhanced the adipogenic differentiation ability of Gli1⁺-MSC. After fibrogenesis induction, the protein expressions of PDGFRα, α-SMA and FSP-1 in the experimental group (0.030±0.001, 0.932±0.177 and 0.276±0.020, respectively) were significantly lower than those in the control group (0.439±0.006, 1.352±0.170 and 0.835±0.097, respectively) (t=149.40, P<0.001; t=66.38,P<0.001; t=11.41,P<0.08). This suggested that the knock-out of PDGFRα significantly inhibited Gli1⁺-MSC differentiation toward fibroblasts. After bidirectional induction, significantly less adipocyte formation was seen in the control group and more in the experimental group. Quantitative analysis showed that the amount of oil red O staining in the experimental group (0.461±0.042) was significantly higher than that in the control group (0.017±0.007) after bidirectional induction (t=23.20, P<0.01). Conclusions: PDGFRα plays an important role in the regulation of bidirectional differentiation of vascular adventitial Gli1+-MSC.

MiRNA Profiling and Its Potential Roles in Rapid Growth of Velvet Antler in Gansu Red Deer (Cervus elaphus kansuensis)

A significant variety of cell growth factors are involved in the regulation of antler growth, and the fast proliferation and differentiation of various tissue cells occur during the yearly regeneration of deer antlers. The unique development process of velvet antlers has potential application value in many fields of biomedical research. Among them, the nature of cartilage tissue and the rapid growth and development process make deer antler a model for studying cartilage tissue development or rapid repair of damage. However, the molecular mechanisms underlying the rapid growth of antlers are still not well studied. MicroRNAs are ubiquitous in animals and have a wide range of biological functions. In this study, we used high-throughput sequencing technology to analyze the miRNA expression patterns of antler growth centers at three distinct growth phases, 30, 60, and 90 days following the abscission of the antler base, in order to determine the regulatory function of miRNA on the rapid growth of antlers. Then, we identified the miRNAs that were differentially expressed at various growth stages and annotated the functions of their target genes. The results showed that 4319, 4640, and 4520 miRNAs were found in antler growth centers during the three growth periods. To further identify the essential miRNAs that could regulate fast antler development, five differentially expressed miRNAs (DEMs) were screened, and the functions of their target genes were annotated. The results of KEGG pathway annotation revealed that the target genes of the five DEMs were significantly annotated to the "Wnt signaling pathway", "PI3K-Akt signaling pathway", "MAPK signaling pathway", and "TGF-β signaling pathway", which were associated with the rapid growth of velvet antlers. Therefore, the five chosen miRNAs, particularly ppy-miR-1, mmu-miR-200b-3p, and novel miR-94, may play crucial roles in rapid antler growth in summer.

The influence of pet ownership on self-compassion among nurses: a cross-sectional study

Background

The modern lifestyle trend of pet ownership is undoubtedly beneficial for both physical and mental health. Research has shown a connection between pet ownership and staff self-compassion. However, there has not been any evidence linking pet ownership to self-compassion in the nurse population.

Aims

To investigate the current status of pet ownership among nurses and explore the influence of pet ownership on self-compassion among nurses.

Methods

An online survey was conducted in July 2022 with 1,308 nurses in China. Data were collected using a general information questionnaire and a self-compassion scale. To compare categorical variables, the independent t test, one-way ANOVA, and multiple linear regression analysis were utilized. SPSS software was used for the statistical analysis.

Results

We found that 16.9% of nurses owned at least one pet, and dogs and cats were the primary pets. The t test for independent samples showed that pet owners and non-pet owners scored differently on self-compassion (t = 3.286, p = 0.001), self-kindness (t = 3.378, p = 0.001), common humanity (t = 2.419, p = 0.016), and mindfulness (t = 2.246, p = 0.025). One-way ANOVA revealed that the highest degree was an influencing factor of self-compassion (χ ² = 1.386, p = 0.019). Multiple linear regression showed that average monthly income, pet ownership, and highest degree were the factors that influenced self-compassion most significantly (F = 8.335, p < 0.001).

Conclusion

The results revealed that nurses actually own pets as part of their modern lifestyle, which provides them with social support and potentially enhances their self-compassion. More efforts should be focused on the impact of pet ownership on nurses' physical and mental health, and pet-based interventions should also be developed.

Relationship among clinical practice environment, creative self-efficacy, achievement motivation, and innovative behavior in nursing students: A cross-sectional study

BACKGROUND

Innovation is essential to advance nursing and health care. However, few studies have focused on innovative behavior of nursing students.

OBJECTIVES

The purpose of this study was to explore the mediating effects of creative self-efficacy and achievement motivation on the relationship between clinical practice environment and innovative behavior in Bachelor of Science in Nursing (BSN) students.

DESIGN

A descriptive cross-sectional study using an online questionnaire.

SETTING

Participants were recruited online from five practice hospitals in Henan Province, China.

PARTICIPANTS

A total of 588 BSN students enrolled in the study.

METHODS

The participants completed the innovative behavior questionnaire, the clinical practice environment scale, the achievement motivation scale, and the creative self-efficacy scale online in 2022. SPSS PROCESS macro was used for data analysis. The reporting followed the STROBE checklist.

RESULTS

A total of 499 valid questionnaires were collected. A positive clinical practice environment was associated with more innovative behavior, and this relation was partially mediated by creative self-efficacy and motive to avoid failure.

CONCLUSION

Our study complements the evidence on the mechanism of action between the clinical practice environment and innovative behavior. Our findings have important implications for nursing educators to develop education strategies to inspire nursing students to pursue innovations in school and clinical settings.

Benefit finding in first-ever young and middle-aged patients who had a stroke and their spousal caregivers in China: a longitudinal mixed-methods study protocol

INTRODUCTION

The global burden caused by stroke is shifting to young and middle-aged people. Researchers have emphasised the significance of benefit finding (BF) in psychological health. However, current research has paid little attention to stroke and has discussed BF from only a single perspective, that is, that of either patients or caregivers. Our study aims to understand the changing trajectory, predictors and dyadic interaction of BF in dyads of patient who had a stroke and caregiver.

METHODS AND ANALYSIS

This study is a longitudinal mixed-methods, multicentre study. A total of 142 patients who had a stroke and 142 spousal caregivers will be investigated. Participants will be recruited from four large public hospitals in northern China. Quantitative and qualitative data will be collected at five time points (near discharge and 1, 3, 6 and 12 months following discharge). Validated and reliable questionnaires will be used in quantitative studies. Information on sociodemographic data, BF, functional status, perceived stress, coping styles and mutuality will be collected from the dyads. Qualitative data will be collected via semistructured interviews and observations. The growth mixture model will be used to analyse quantitative data, and Colaizzi's seven-step analysis method will be used to analyse qualitative data. We plan to conduct parallel but separate quantitative and qualitative data analyses and ultimately integrate the data sets to determine confirmation, expansion or discordance.

ETHICS AND DISSEMINATION

All participants will be provided with an informed consent form. This study will encode all identifiable data and store all recorded data on a secure research server. This study has been approved by the Ethics Review Committee of the College of Nursing and Health, Zhengzhou University (ZZUIRB2020-53). The results of the longitudinal study will be published in peer-reviewed journals and presented at national conferences.

Risk perception of COVID-19 among college students in China: Latent profile analysis

Background

The outbreak of the new coronavirus-2019 (COVID-19) has had a significant impact on people's mental and physical health. Meanwhile, people's perceptions of risk may influence their emotional states and preventative behavior during an epidemic. Previous research have revealed the diversity and uniqueness of risk perception, and college students may have a different perspective on risk perception. The objective of this study was to describe the subtypes of risk perception for COVID-19 among college students in China, identify the subtypes' traits, and investigate their affecting variables.

Methods

College students from 10 Chinese provinces participated in a cross-sectional study (n = 2,000) that from January 16 to 30, 2022. The latent profiles and influencing factors for risk perception were investigated using latent profile analysis, one-way analysis of variance, and multinomial logistical regression.

Results

The sample group of this survey was 1,946 students, and the response rate was 97.3%. The best model was suggested to consist of three profiles: "neutral risk perception" (20.3%), "perception seriously without susceptible" (52.8%), and "low risk perception" (26.9%). Risk perception of COVID-19 was positively associated with attention to negation information (r = 0.372, p < 0.01), anxiety (r = 0.232, p < 0.01), and depression (r = 0.241, p < 0.01), and negatively associated with perceived social support (r = -0.151, p < 0.01). Logistic-regressions analyses mainly revealed that the risk perception of three profiles related to having chronic diseases (OR = 2.704, p < 0.01), medical major (OR = 0.595, p < 0.01; OR = 0.614, p < 0.05), without having COVID-19 confirmed cases around (OR = 0.539, p < 0.01), attention to negative information (OR = 1.073, p < 0.001; OR = 1.092, p < 0.001), and perceived social support (OR = 0.0.975, p < 0.01).

Conclusions

The level of risk perception for COVID-19 among Chinese college students was unsatisfactory, and the risk perception of COVID-19 had significant group characteristics and heterogeneity. Colleges and public health practitioners could have a theoretical and empirical basis to implement risk perception intervention efforts by identifying latent subgroups during the COVID-19 epidemic.

Effects of A Benefit-Finding Intervention in Stroke Caregivers in Communities

Objectives: To verify the effectiveness and feasibility of a nine-week benefit-finding intervention on the burden, quality of life, and benefit finding of caregivers, as well as on the quality of life of stroke survivors.Methods: Benefit finding refers to the individual, social, psychological and spiritual benefits perceived by an individual experiencing stress or post-traumatic events. A randomized controlled trial was performed in which 68 stroke survivors and their caregivers were recruited from the Zhengzhou community, China, and randomly split into two groups. The intervention group included those having undergone a nine-week benefit-finding intervention, while the control group included those individuals having undergone a nine-week routine health education. At baseline and one-week post-intervention (after a 9-week intervention), the quality of life of stroke survivors and caregivers and the burden and benefit finding of caregivers were determined.Results: In comparison to the control group, caregiver benefit finding, quality of life, burden, and stroke survivor quality of life were significantly improved (P <.005).Conclusions: The intervention appears to be feasible for stroke patients and caregivers. The intervention is capable of improving the quality of life of caregivers and survivors, increasing the benefit finding of caregivers and reducing the burden of caregivers.Clinical Implications: The benefit-finding intervention is capable of improving the health condition of stroke patients and caregivers.

RNA sequencing-based identification of microRNAs in the antler cartilage of Gansu red deer (Cervus elaphus kansuensis)

Background

The velvet antler is a complex mammalian bone organ with unique biological characteristics, such as regeneration. The rapid growth stage (RGS) is a special period in the regeneration process of velvet antler.

Methods

To elucidate the functions of microRNAs (miRNAs) at the RGS of antler development in Gansu red deer (Cervus elaphus kansuensis), we used RNA sequencing (RNA-seq) to analyze miRNA expression profiles in cartilage tissues of deer antler tips at three different growth stages.

Results

The RNA-seq results revealed 1,073 known and 204 novel miRNAs, including 1,207, 1,242, and 1,204 from 30-, 60-, and 90-d antler cartilage tissues, respectively. To identify key miRNAs controlling rapid antler growth, we predicted target genes of screened 25 differentially expressed miRNAs (DEMs) and specifically expressed miRNAs (SEMs) in 60 d and annotated their functions. The KEGG results revealed that target genes of 25 DEMs and 30 SEMs were highly classified in the "Metabolic pathways", "Pathways in cancer", "Proteoglycans in cancer" and "PI3K-Akt signaling pathway". In addition, a novel miRNA (CM008039.1_315920), highly enriched in "NF-kappa B signaling pathway", may need further study.

Conclusions

The miRNAs identified in our study are potentially important in rapid antler growth. Our findings provide new insights to help elucidate the miRNA-mediated regulatory mechanisms involved during velvet antler development in C. elaphus kansuensis.

A Chinese version of the Measure of Stroke Environment (MOSE): psychometric evaluation in stroke survivors

PURPOSE

To translate the MOSE from English to Chinese and investigate the psychometric properties of the Chinese-translated version of the Measure of Stroke Environment (MOSE).

MATERIALS AND METHODS

The MOSE was translated into Chinese using a cultural adaptation process. To validate this Chinese version, 311 stroke survivors were recruited to complete the questionnaire. The psychometric properties of the MOSE were evaluated by determining item analysis, test-retest reliability, internal consistency, content validity, construct validity, and floor/ceiling effects, respectively.

RESULTS

The MOSE was translated without any major difficulties. Regarding psychometric performances, a moderate level of correlation between the items and the domains (r > 0.4), and the significant differences in items between the high group and the low group were tested by independent sample t-tests (p < 0.05). The test-retest reliability was excellent (Intraclass Coefficient Correlation = 0.938). Very high internal consistency was also observed (Cronbach's α = 0.945, split-half reliability = 0.778). An acceptable I-CVI ranged from 0.714 to 1.000 and a high S-CVI of 0.973. Correlations with the subscales of the WHODAS 2.0 were significant in similar domains reflecting good convergent validity. No floor or ceiling effects were observed.

CONCLUSION

This study provides psychometric evidence supporting the use of the Chinese version of the MOSE among stroke survivors.IMPLICATIONS FOR REHABILITATIONThe Measure of Stroke Environment was translated into Chinese through a rigorous cultural adaptation process.MOSE-C is now a reliable and valid tool for Chinese-speaking survivors who have suffered from a stroke.It is necessary to assess the perceived environmental barriers of stroke survivors and develop targeted intervention programs in China.

Reliability and validity of the Chinese version of the Family Resilience Questionnaire (FaRE Questionnaire) in patients with breast cancer: a cross-sectional study

OBJECTIVE

The aim of this study was to assess the reliability and validity of the Chinese version of the Family Resilience (FaRE) Questionnaire among patients with breast cancer in China.

DESIGN

It was a cross-sectional study, which involved translation, back-translation, cultural adjustment and psychometric testing of a 24-item FaRE Questionnaire.

SETTING

Three tertiary hospitals in Zhengzhou, China: respectively are the First Affiliated Hospital of Zhengzhou University, Second Hospital Affiliated to Zhengzhou University and Henan Provincial People's hospital.

PARTICIPANTS

A total of 559 patients with breast cancer volunteered to participate in the study PRIMARY OUTCOME MEASURES: Data analysis was performed using the IBM SPSS software V.21.0 and AMOS software V.21.0. Cronbach's α coefficient was used to examine the internal consistency. The test-retest reliability was calculated using the intraclass correlation coefficient on 30 participants. The content validity index was calculated based on the values obtained from six expert opinions. Construct validity test was performed using factor analysis including exploratory factor analysis and confirmatory factor analysis.

RESULTS

For the Chinese version of FaRE Questionnaire, the Cronbach's α coefficient of the total questionnaire was 0.909, and Cronbach's α coefficients of four factors were 0.902, 0.932, 0.905 and 0.963, respectively. The test-retest reliability index of the total questionnaire was 0.905. The Scale-Content Validity Index was 0.97, and Item-Content Validity Index ranged from 0.83 to 1.00. The questionnaire included 24 items, exploratory factor analysis extracted four factors with loading >0.4, which could explain 72.146% of the total variance. Confirmatory factor analysis showed the Chinese version of FaRE Questionnaire had an excellent four-factor model consistent with the original questionnaire.

CONCLUSION

The Chinese version of FaRE Questionnaire has acceptable reliability and validity among patients with breast cancer in China. It can effectively assess family resilience and provide basis for personalised family resilience interventions for patients with breast cancer.

Assessing the psychometric properties of the Chinese return-to-work self-efficacy questionnaire using Rasch model analysis

Background

Self-efficacy is a significant predictor of return to work and affects the confidence of survivors to return to work after illness. The Return-to-work self-efficacy (RTW-SE) questionnaire is a self-report questionnaire to assess confidence in returning to work with good reliability and validity. The aim of this study was to translate and cross-culturally adapt the RTW-SE questionnaire into Chinese and examine the psychometric properties among young and middle-aged stroke survivors using Rasch model analysis.

Methods

The cross-cultural adaptation and translation procedures followed a dual-translation approach. The psychometric properties of the RTW-SE questionnaire were examined using Rasch model analysis by Winsteps software. The unidimensionality and local independence were analyzed by principal component analysis of the residuals (PCAR) and standardized residual correlations.Category diagnostics were performed for scale function, and the item fit, reliability, and separation were also validated. Item-person maps were used to examine the distribution and matching of item’s location and person ability. Finally, the differential item functioning (DIF) was used to measure gender-related group equivalence.

Results

A total of 366 participants aged 23–59 years were recruited from three communities in Zhengzhou. The RTW-SE questionnaire demonstrated unidimensionality and a 5-point Likert rating scale was more appropriate to investigate young and middle-aged stroke survivors’self-efficacy. There was a good fit for the items with both person and item reliabilities greater than 0.8 and separation indices of 3.75 and 3.94, respectively. The item location was identified from the item-person map as not covering person ability, but the scale did not have an age-related DIF.

Conclusions

The results confirm evidence of appropriate psychometric properties of the RTW-SE questionnaire and can be used as a reliable and validated instrument for measuring self-efficacy to return to work in young and middle-aged Chinese patients with stroke.

Effect of SGLT2 Inhibitors on Risk of Stroke in Diabetes: A Meta-Analysis

BACKGROUND

The effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on reducing the risk of stroke in patients with type 2 diabetes mellitus (T2DM) remains unclear. Thus, we conducted this systemic review and meta-analysis of all relevant studies and trials to explore the role of SGLT2 inhibitors on the stroke prevention.

METHODS

The present study included articles published before October 2021 and searched in Web of Science, PubMed databases. We used STATA 12.0 software to compute hazard ratio (HR) and 95% confidence interval (CI).

RESULTS

Meta-analysis indicated that SGLT2 inhibitors showed no significant effects on risk of stroke in diabetes in randomized controlled trials with a fixed effects model (HR = 0.98; 95% CI: 0.88-1.09, I2 = 22.3%, p = 0.272). Compared to other glucose-lowering drugs (oGLD) and insulin, SGLT2 inhibitors alone significantly affected risk of stroke in diabetes in observational studies with a random effects model (HR = 0.87; 95% CI: 0.80-0.95, I2 = 72.2%, p < 0.001).

CONCLUSIONS

In summary, this meta-analysis indicated that the use of SGLT2 inhibitors did not decrease the risk of stroke. And for some T2DM patients with high-risk factor of stroke, SGLT2 inhibitors therapy may be more suitable compared to some oGLD such as dipeptidyl peptidase-4 inhibitors. The results of this meta-analysis are necessary to be confirmed with further studies and clinical trials.

[Transoral endoscopic resection of benign tumors in parapharyngeal space via medial pterygomandibular raphe approach]

Objective: To explore the surgical methods and effects of transoral endoscopic resection of benign tumors in parapharyngeal space via medial pterygomandibular raphe approach. Methods: The clinical data of 23 patients who underwent resection of benign tumors in parapharyngeal space by endoscopic medial pterygomandibular raphe approach from January 2016 to July 2020 in the Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University were analyzed retrospectively. There were 14 males and 9 females with a median age of 43 years. The tumors were located in the anterior space of the styloid process in 13 cases and in the posterior space in 10 cases. The smallest tumor volume was 7.3 ml and the largest was 80.2 ml. The preoperative imaging features, the characteristics and risks of this approach in the operation were analyzed, and the feasible mode of operation was explored. Results: All patients completed the operation successfully. The intraoperative blood loss was 20 to 50 ml, with an average of 28.3 ml. The operation time was 40 to 110 min, with an average of 75.4 min. The incision length was 2 to 4 cm, with an average of 3.0 cm. The postoperative pain score was 2 to 4, with an average of 3.2. The postoperative hospital stay was 4 to 9 d, with an average of 6.7 d. Postoperative pathological diagnosis included pleomorphic adenoma (n=12), neurilemmoma (n=10) and basal cell adenoma (n=1). The patients were followed up for 6 to 60 months. There was no postoperative complication such as infection or serious bleeding, and there was no tumor recurrence after operation. Conclusion: Endoscopic resection of benign tumor in parapharyngeal space via medial pterygomandibular raphe approach is a safe, effective, and minimally invasive surgical method for the treatment of tumors in parapharyngeal space.

Decreased Serum Brain-Derived Neurotrophic Factor in Poststroke Depression: A Systematic Review and Meta-Analysis

BACKGROUNDS

There were conflicting results on the comparison of brain-derived neurotrophic factor (BDNF) levels between poststroke depression (PSD) patients and stroke patients without PSD among previous studies. Thus, we conducted this systemic review and meta-analysis to explore the alteration of serum BDNF levels in PSD.

METHODS

This study included articles from the Web of Science and PubMed databases that were published before December 2021. STATA 12.0 software was used to compute the standardized mean difference (SMD) and 95% confidence interval (CI) regarding the comparison of serum BDNF in PSD and stroke patients without PSD.

RESULTS

We collected the mean value and standard deviation (SD) of serum BDNF in PSD and stroke patients without PSD from six studies (PSD: n = 268, stroke patients without PSD: n = 425). The present meta-analysis showed decreased serum BDNF level in patients with PSD, compared to stroke patients without PSD with a random-effects model (mean value of BDNF level [PSD vs. stroke patients without PSD]: 14.106 vs. 17.995 ng/ml; SMD = -1.578; 95% CI: -2.820, -0.337; I ² = 97.8%, p-value for Q test < 0.001).

CONCLUSION

Brain-derived neurotrophic factor may work as a potential biomarker to predict the risk of PSD among stroke survivors. More large-sample clinical trials exploring the alteration of serum BDNF levels in PSD among stroke patients need to be conducted to verify this result.

The Influential Factors of Adherence to Physical Activity and Exercise among Community-Dwelling Stroke Survivors: A Path Analysis

AIMS AND OBJECTIVES

To investigate the status of physical activity and exercise (PAE) adherence and identify its influential factors among community-dwelling stroke survivors.

BACKGROUND

Regular PAE after stroke is essential for recovery and secondary prevention, while adherence to PAE and its influential factors are rarely studied.

DESIGN

A cross-sectional descriptive study.

METHODS

In total, 208 stroke survivors (70.25 ± 9.08 years) were randomly selected from three communities. The influential factors of PAE adherence and associations between these variables were explored using multiple linear regression and path analyses. This study adhered to the EQUATOR checklist, STROBE.

RESULTS

The mean adherence rate was moderate (62.00%), and stroke survivors tended to be more adherent to PAE than monitoring and seeking advice (70.30%>53.50%>48.30%). The regression results revealed that seven factors were significantly associated with PAE adherence, including knowledge, attitude, self-efficacy, social support, self-care ability, community rehabilitation experience and times since stroke. Furthermore, the path analysis showed that knowledge had a significant indirect positive influence on adherence with self-efficacy as a mediator, while attitude and social support impacted both directly and indirectly with self-efficacy as the mediator. Moreover, self-efficacy had the most substantial direct effect on community-dwelling stroke survivors' PAE adherence. These four variables accounted for a total of 67.00% of the variance in PAE adherence among community-dwelling stroke survivors.

CONCLUSIONS

The PAE adherence of community stroke survivors needs to be improved. Healthcare professionals should develop more effective interventions to promote PAE adherence through enhancing self-efficacy among this population.

RELEVANCE TO CLINICAL PRACTICE

Adherence to the recommended regimen is the most challenging dimension of stroke physical activity and exercise. This study contributes to exploring status and influential factors of PAE adherence, and self-efficacy was found to be a significant determinant. The results could be used to inspire future community-based intervention programs for stroke survivors.

Qualitative study of Stroke Survivors' Perceptions of Secondary Prevention

AIMS

To understand how survivors of stroke perceive secondary prevention and explore their perceived barriers and facilitators using the Theoretical Domains Framework.

DESIGN

A qualitative descriptive study.

METHODS

Nineteen survivors of stroke from three hospitals were recruited and interviewed from April 2019 to April 2020. The data were analysed deductively and inductively by content analysis strategies.

RESULTS

Three main themes of perception of secondary prevention were identified, these being active treatment-seeking, attention to taking medications and negative attitude towards lifestyle changes. Using deductive analysis, eight domains of the Theoretical Domains Framework were reported to be relevant in the secondary prevention behaviour of survivors of stroke that mapped to five 'barrier' domains (i.e. knowledge, physical skills, beliefs about capability, beliefs about consequences and optimism) as well as six 'facilitator' domains (i.e. knowledge, interpersonal skills, beliefs about capability, intention, emotion and social influences). Using inductive analysis we identified two additional important factors not falling in the domains of the Theoretical Domains Framework. These comprised female spouses' support and patients' economic autonomy, both of which could be classified as a facilitator or barrier.

CONCLUSION

Survivors of stroke perceive seeking treatment and using preventive medication as more important than modifying lifestyle behaviours. Knowledge and insight into the barriers and facilitators of secondary prevention in this specific context provides a theoretical and practical basis for the design of future secondary prevention interventions.

IMPACT

Stroke survivors' perceptions of secondary prevention, barriers and facilitators were explored in the context of a developing country. These findings highlight the need to better communicate the importance of improving lifestyle modification and medication adherence, and provide evidence for designing relevant interventions for stroke management in the community.

Perceptions of recurrence risk and behavioural changes among first-ever and recurrent stroke survivors: A qualitative analysis

Background

Among stroke survivors, the risk of stroke recurrence is high, and stroke survivors' perception of the risk of recurrence is crucial to promote healthy behaviours.

Objectives

This study aimed to explore the perceptions of stroke survivors about their risk of recurrence and healthy behavioural modifications.

Design

A qualitative interview study was carried out.

Results

We interviewed 19 stroke survivors from 3 hospitals. Thematic analysis showed that the perceptions of recurrence risk and healthy behavioural changes differed between first‐ever and recurrent stroke survivors. Three themes were generated from the data of first‐ever stroke survivors: indifference to and unawareness of the risk of stroke recurrence, the need for professional information support and different awareness of the importance of different healthy behaviours. For first‐relapse stroke patients: worry but feel powerlessness towards recurrent event, accurate information is still warranted, regret of unhealthy behaviour patterns. For the survivors suffered two or more times recurrences: perceived severity of recurrences, increased psychological care need, incorrect perceptions of healthy behaviour.

Discussion and Conclusion

Stroke survivors with or without recurrence hold different perceptions towards the risk of recurrence and behavioural changes. The need for information related to warning signs, recurrence risk and risk factors remained consistently unmet. The benefits of healthy behaviours could be a double‐edged sword for the prevention of stroke recurrence if the survivors fail to understand these accurately. It is strongly recommended that a specific recurrence risk communication tool and related health education plan be explored on the basis of the number of times patients have experienced stroke recurrence to inform secondary prevention of stroke in the future.
