Factors associated with health behaviours among stroke survivors: A mixed-methods study using COM-B model.

AIMS: To identify factors associated with health behaviours among stroke survivors, through a multi-centre study. DESIGN: A sequential mixed methods design. METHODS: In the quantitative research phase, a total of 350 participants were recruited through multi-stage sampling from December 2022 to June 2023. General information questionnaires, The Stroke Prevention Knowledge Questionnaire (SPKQ), Short Form Health Belief Model Scale (SF-HBMS), Health Promoting Lifestyle Profile (HPLPII), and the WHOQOL-BREF (World Health Organization Quality of Life Questionnaire, Brief Version) were distributed across five tertiary hospitals in Henan province, China. For the qualitative research component, semi-structured interviews were conducted to explore the barriers and facilitators of health behaviour. This study adheres to the GRAMMS guidelines. RESULTS: A total of 315 participants (90.0%) completed the survey. Identified barriers to health behaviour included residing in rural areas, higher scores on the Charlson Comorbidity Index (CCI) and mRS, as well as lower scores on SPKQ, SF-HBMS and WHOQOL-BREF. Twenty-four individuals participated in qualitative interviews. Twenty-eight themes were identified and categorised by frequency, covering areas such as knowledge, skills, intentions, social influences, social/professional role and identity, environmental context and resources, beliefs about capabilities, beliefs about consequences and behavioural regulation. Both quantitative and qualitative data suggested that health behaviour among stroke survivors is at a moderate level, and the identified barrier factors can be mapped into the COM-B model (Capability, Opportunity, Motivation and Behaviour). CONCLUSION: The study indicates that key barriers to health behaviour among stroke survivors align with the COM-B model. These identified factors should be carefully considered in the planning of future systematic interventions aimed at improving health behaviours among stroke survivors. PATIENT OR PUBLIC CONTRIBUTION: Patients were invited to completed questionnaires in the study and semi-structured interviews. The investigators provided explanation of this study' content, purpose and addressed issues during the data collection.

A Chinese version of the Stroke Illness Perception Questionnaire-Revised: Reliability and validity assessment in stroke patients.

BACKGROUND: Illness perceptions are an important factor affecting the prognosis of stroke patients. Evaluating the illness perceptions of stroke patients is of great importance for predicting their health behaviour and rehabilitation outcomes. However, there is no specific tool for assessing illness perceptions in stroke patients in China. OBJECTIVES: The objective of this study is to translate the Stroke Illness Perception Questionnaire-Revised (SIPQ-R) into Chinese and to psychometrically test the Chinese version of the scale in the population of Chinese stroke patients. METHODS: This was a methodological study. We investigated 593 stroke patients in the neurology department of a hospital in China from March to September 2021. We translated the SIPQ-R and adapted it to the cultural context, after which we evaluated the reliability and validity of the Chinese version of SIPQ-R. RESULTS: Exploratory factor analysis identified eight common factors that accounted for 71.74% of the total variance, and the factor loadings ranged from 0.530 to 0.933. Confirmatory factor analysis confirmed the eight-factor structure (χ2/df = 1.765, root mean square error of approximation = 0.053, incremental fit index = 0.906, comparative fit index = 0.905 and Tucker-Lewis index = 0.900). Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.982. The test-retest reliability was 0.762. The results showed good content validity (the scale level content validity index was 0.940, and the item level content validity index values ranged from 0.860 to 0.960). There were no missing responses and floor or ceiling effects. The standard error of measurement and the smallest detectable change for the SIPQ-R were 45.49 and 126.10, respectively. CONCLUSIONS: The results of this study provide empirical evidence for the reliability and validity of the Chinese version of the SIPQ-R for stroke patients.

Robot-assisted rehabilitation training improves knee function and daily activity ability in older adults following total knee arthroplasty.

To evaluate the effects of robot-assisted rehabilitation training on knee function and the daily activity ability of older adults following total knee arthroplasty (TKA). Eighty-eight patients who underwent TKA were randomly assigned to a robot-assisted rehabilitation or traditional therapy group. The patients in the control group were treated with traditional manual rehabilitation therapy, while the patients in the experimental group were subjected to the robot-assisted rehabilitation program. Range of motion of the knee joint, Hospital for Special Surgery Knee Rating Score, and the modified Barthel Index were assessed on the first or second day after TKA (preintervention) and the discharge day (postintervention). Additionally, the length of hospital stay and related hospitalization expenses of the two groups were collected on the discharge day. Improvements in the active range of motion (p < 0.001), passive range of motion (p = 0.001), Hospital for Special Surgery Knee Rating Score (p < 0.001), and modified Barthel Index score (p = 0.004) were significantly better in the robot-assisted rehabilitation group than in the traditional therapy group. Interestingly, the length of hospital stay in the experimental group (9 days) was shorter than that in the control group (13 days), and the total cost of hospitalization was lower (p = 0.002). The robot-assisted rehabilitation training program is an effective intervention that significantly improves the daily activity ability and knee function of older adults following TKA.

Factor analysis of the Chinese version of the Self-care Ability Scale for the Elderly: A multi-centre cross-cultural validation study.

AIM: This study aimed to explore and confirm the factor structure and item distribution of the Chinese version of Self-care Ability Scale for the Elderly among older Chinese people. METHODS: A cluster random sampling method was used to collect 2856 older people from five different cities of China from July 2018 to July 2019. A questionnaire comprised of socio-demographic information and the Chinese version of the Self-care Ability Scale for the Elderly was administered, and SPSS 21.0 and Mplus 7.4 were used for analyses. RESULTS: Participants were aged 60 to 92 years, with a mean age of 71.52 (SD = 7.68) years. In the Exploratory Factor Analysis, the three-factor structure and item distribution of the Chinese version of the Self-care Ability Scale for the Elderly were verified to be better than other options. The factor loadings varied from 0.428 to 0.800, and the communality values ranged from 0.426 to 0.792. The modified model showed a good fit in the Confirmatory Factor Analysis. CONCLUSION: The Chinese version of the Self-care Ability Scale for the Elderly has a clear three-factor structure and a good item distribution. It serves as a convenient and accurate assessment tool to assess the self-care ability of older Chinese people.

Association between illness perception and health behaviour among stroke patients: The mediation effect of coping style.

AIMS: This study aims to explore illness perception and coping style in relation to health behaviour and the mediating role of coping style between illness perception and health behaviour among stroke patients. DESIGN: Cross-sectional study. METHODS: This survey was conducted with 515 stroke patients aged ≥18 years from September 2019 to January 2020 in Zhengzhou, China. The demographic and clinical characteristics questionnaire, Stroke Illness Perception Questionnaire-Revised, Simplified Coping Style Questionnaire, and Health Behavior Scale for Stroke Patients were included in this study. Data analysis was performed by correlation analysis, multiple linear regression analysis, and structural equation modelling. RESULTS: The valid questionnaires were 495 (effective response rate: 96.1%). Low negative illness perception, high positive coping style, and low negative coping style are related to high level of health promoting behaviour (all p < 0.01). The results revealed that the effect of illness perception on health behaviour was partly mediated by coping style. It also confirmed that the mediation effect accounts for 43.7% (-0.169/-0.387) of the total effect. CONCLUSION: Illness perception may influence health behaviour partly because of coping style. IMPACT: This study implies that targeted interventions for stroke patients' illness perception are needed to motivate them to take proactive coping strategy to ultimately improve their health behaviours.

Targeting ß-tubulin/CCT-ß complex induces apoptosis and suppresses migration and invasion of highly metastatic lung adenocarcinoma.

Metastasis, the movement of cancer cells from one site to another, is responsible for the highest number of cancer deaths, especially in lung cancer patients. In this study, we first identified a prognostic marker of lung adenocarcinoma, TCP-1 ß subunit (chaperonin-containing TCP-1ß; CCT-ß). We showed a compound that disrupted the interaction of CCT-ß with ß-tubulin killed a highly metastatic non-small cell lung cancer cell line CL1-5 through inducing Endoplasmic reticulum stress and caspases activation. Moreover, at the dosage of EC20, the compound inhibited migration and invasion of the lung cancer cells by suppressing matrix metalloproteinase (MMP)-2/9 and epithelial-mesenchymal transition (EMT)-related proteins through downregulating mitogen-activated protein kinases (MAPKs), Akt/ß-catenin and integrin-focal adhesion kinase signaling pathways. Unlike the anticancer drugs, such as Taxol, that target the adenosine triphosphate site of ß-tubulin, this study reveals a therapeutic target, ß-tubulin/CCT-ß complex, for metastatic human lung adenocarcinoma. The study demonstrated CCT-ß as a prognostic marker. Targeting ß-tubulin/CCT-ß complex caused apoptosis and inhibited invasion/migration of CCT-ß overexpressed, highly metastatic lung adenocarcinoma.

Identification of health behaviour clusters among people at high risk of stroke: A latent class profile analysis.

AIMS: To identify the possible latent classes of health behaviour reported by people at high risk of stroke and to explore the predictors of these different classes of health behaviour. DESIGN: A cross-sectional survey study. METHODS: A stratified cluster random sampling method was used to collect data from 2,500 individuals at high risk of stroke who were from Henan Province, China, from January 2018-January 2019. A latent class profile analysis was used to identify the health behaviour clusters and multinomial logistic regression was used to determine which factors predicted the emergent latent classes of health behaviour. RESULTS: High-risk individuals (N = 2,236) at high risk of stroke replied to the survey (89.44% response rate). Model fit indices (AIC = 257,509.610, BIC = 260,228.733, Entropy = 0.956) supported a three-class model of health behaviours. The latent classes were Class 1 (a good level of adaptive health behaviour, 31%, N = 693), Class 2 (a moderate level of adaptive health behaviour, 36%, N = 805) and Class 3 (a poor level of adaptive health behaviour, 33%, N = 738); Based on physical and belief, behaviour and clinical profiles, the three classes were further labelled self-realization deficiency subgroup, social contact anxiety subgroup and health responsibility absence subgroup respectively. Older age, male gender, no spouse, lower education and household income were risk factors associated with good health behaviour. After controlling these socio-demographic variables, high levels of health-related knowledge and attitude were the main positive predictors of health behaviour. CONCLUSIONS: This study has identified three different latent classes of health behaviour and their predictive factors in people at high risk of stroke in the Chinese setting. IMPACT: This study has significance for the promotion of adaptive health behaviour in individuals at high risk of stroke. It has allowed the identification of specific clusters of health behaviour that vary in terms of their adaptiveness and forms the basis for the development of a targeted intervention to promote health behaviour for each different subgroup.

Cross-Cultural Adaptation, Reliability, and Validity of the Chinese Version of the Tampa Scale for Kinesiophobia-11 Among Patients Who Have Undergone Total Knee Arthroplasty.

BACKGROUND: The shortened version of the Tampa Scale for Kinesiophobia (TSK-11) has been well characterized in the literature. However, to the best of our knowledge, no previous studies have evaluated the reliability and validity of the TSK-11 for Chinese-speaking patients who have undergone total knee arthroplasty (TKA). Thus, the objectives of this study were to translate and adapt the TSK-11 cross-culturally into Chinese and to evaluate its reliability and validity in a sample of Chinese TKA patients. METHODS: The TSK-11 was translated and cross-culturally adapted into Chinese according to the international guidelines for the cross-cultural adaptation of self-report measures. The Chinese version of TSK-11 was administered to 254 patients following their TKA, along with the Fear-Avoidance Beliefs Questionnaire, Pain Catastrophizing Scale, Numerical Rating Scale, and 12-Item Short Form Health Survey. Psychometric testing included internal consistency, test-retest reliability, floor and ceiling effects, construct validity, and convergent validity. RESULTS: A high completion rate of 95.8% with no floor or ceiling effects was noted in the Chinese version of the TSK-11. The questionnaire also showed good internal consistency (Cronbach's α = 0.883) and test-retest reliability (intraclass correlation coefficient = 0.798). Construct validity was assessed by exploratory factor analysis, and 3 factors were extracted that accounted for 65.2% of the variance. Convergent validity was confirmed by significant Pearson correlations between the Chinese version of the TSK-11 and the Pain Catastrophizing Scale (r = 0.751), Fear-Avoidance Beliefs Questionnaire (r = 0.719) and VAS (r = 0.450), as well as the 12-Item Short Form Health Survey subdomains Bodily Pain (r = -0.391), Mental Health (r = -0.356), Physical Functioning (r = -0.339), Role-Emotional (r = -0.317), and Role-Physical (r = -0.277). CONCLUSION: The Chinese version of the TSK-11 demonstrated satisfactory acceptability, reliability, and validity; therefore, it can be used in clinical practice and research for assessing kinesiophobia in Chinese patients after TKA.

Highly sensitive fluorogenic sensing of L-Cysteine in live cells using gelatin-stabilized gold nanoparticles decorated graphene nanosheets.

A highly sensitive and selective fluorogenic sensing of L-Cysteine (L-Cys) was implemented based on gelatin stabilized gold nanoparticles decorated reduced graphene oxide (rGO/Au) nanohybrid. The rGO/Au nanohybrid was prepared by the one-pot hydrothermal method and well characterized by different physiochemical techniques. The nanohybrid exhibits a weak fluorescence of rGO due to the energy transfer from the rGO to Au NPs. The rGO/Au nanohybrid shows enhanced fluorescence activity due to the restoration of quenched fluorescence of rGO/Au nanohybrid in presence of L-Cys. The rGO/Au nanohybrid exhibits much lower detection limit of 0.51 nM for L-Cys with higher selectivity. The fluorescence sensing mechanism arose from the fluorescence recovery due to the stronger interaction between Au NPs and L-Cys, and consequently, the energy transfer was prevented between rGO and Au NPs. The practicability of rGO/Au sensor was implemented by invitro bioimaging measurements in Colo-205 (colorectal adenocarcinoma) and MKN-45 (gastric carcinoma) cancer live cells with excellent biocompatibility.

Does a Program Based on Cognitive Behavioral Therapy Affect Kinesiophobia in Patients Following Total Knee Arthroplasty? A Randomized, Controlled Trial With a 6-Month Follow-Up.

BACKGROUND: To evaluate the effects of a cognitive behavioral therapy (CBT) program on kinesiophobia, knee function, pain and pain catastrophizing in patients following total knee arthroplasty (TKA). METHODS: This was a parallel-group, randomized, controlled pilot study in which 100 patients who exhibited kinesiophobia after TKA were randomly assigned to participate in a CBT (experimental group) or standard care (control group) program. Each group included 50 patients. Before intervention (preintervention), 4 weeks after intervention (postintervention), and 6 months after the end of intervention (follow-up), patients were assessed via the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a numerical rating scale, and the Hospital for Special Surgery knee rating scale. Repeated-measures analysis of variance was used to test the significance of each outcome measure. RESULTS: The CBT program had significant group (P < .001), time (P < .001), and group-by-time interaction (P < .001) effects on kinesiophobia, pain catastrophizing, and knee function, and these effects lasted for at least 6 months after the end of the intervention. Pain was reduced in both groups after the intervention, but there were significant time and group effects (P = .003) in favor of the experimental group. CONCLUSION: The CBT program was superior to standard care in reducing kinesiophobia, pain catastrophizing, and knee pain and in enhancing knee function in patients who have a high level of kinesiophobia following TKA. The treatment effect was clinically significant and lasted for at least 6 months after the end of the intervention.

Incidence and Risk Factors of Kinesiophobia After Total Knee Arthroplasty in Zhengzhou, China: A Cross-Sectional Study.

BACKGROUND: The incidence of and risk factors for kinesiophobia after total knee arthroplasty (TKA) have not been well characterized in the literature. Thus, the aim of this study was to investigate the incidence of postoperative kinesiophobia among patients undergoing TKA and to identify the associated risk factors. METHODS: The simplified Chinese version of the Tampa Scale for Kinesiophobia, Knee Self-Efficacy Scale, Numerical Rating Scale, Simplified Coping Style Questionnaire, and Social Support Rating Scale were used to measure kinesiophobia, self-efficacy, pain intensity, coping styles and social support, respectively. Multivariate logistic regression analyses were utilized to identify the risk factors for postoperative kinesiophobia among TKAs. RESULTS: A total of 862 participants were included in this study. Among all participants, 210 (24.4%) were identified as having kinesiophobia according the Tampa Scale for Kinesiophobia (TSK>37), with a mean score of 32.5 (standard deviation 13.1). A multivariate regression analysis showed that older age (odds ratio [OR] = 2.8, confidence interval [CI] = 2.0-3.7), lower education level (OR = 1.7, CI = 1.3-2.4), negative coping styles (OR = 1.6, CI = 1.0-2.2), less social support (OR = 3.5, CI = 3.1-4.1), lower self-efficacy (OR = 1.4, CI = 1.1-1.7), and greater pain intensity (OR = 2.8, CI = 1.5-5.3) are independent risk factors for kinesiophobia. CONCLUSION: A 24.4% incidence rate of postoperative kinesiophobia was noted in patients following TKA. Older age (most notably ≥76 years old), lower education levels, negative coping styles, greater pain intensity, lower self-efficacy, and less social support were associated with odds of developing postoperative kinesiophobia.

Psychometric Assessment of the Depressive Cognition Scale Among Older Chinese People.

The study aimed to translate the Depressive Cognition Scale (DCS) into Chinese and to test its reliability and validity among Chinese older people. Using a cross-sectional design, a demographic questionnaire and Chinese versions of the Depressive Cognition Scale (DCS-CHI) and the Center for Epidemiological Studies-Depression Scale (CES-D) were administered. The sample consisted of 1673 older people who were from communities and hospitals. The Cronbach's alpha (α) of DCS-CHI was 0.91, and the test-retest correlation coefficient was 0.91 (95% CI, 0.86-0.95, p<0.001). The Content Validity Index (CVI) was found to be good. Exploratory factor analysis (EFA) resulted in a single factor that explained 58.46% of the total variance and all 8 items had strong factor loadings ranging from 0.62 to 0.83; confirmatory factory analysis (CFA) indicated all measurements of the structural model exceeded the recommended criteria, and the single factor solution of DCS-CHI had a good fit (χ2/df=2.45, GFI=0.99, AGFI=0.97, CFI=0.99, TLI=0.99, RMSEA=0.04, RMR=0.01, PCLOSE=0.79). The strong correlation of 0.81 (p<0.01) between the DCS-CHI and CES-D suggested good concurrent validity. Specifying the CES-D as the criterion, the area under the receiver operator characteristic (ROC) curve of the DCS-CHI for the optimal cut-point was 0.941(95%CI:0.919-0.963, p=0.000), the sensitivity and the specificity were 84.7% and 90.7% respectively, suggesting good predictive validity. The findings support the reliability and validity of the DCS-CHI as a measure of depressive cognitions that typically proceed more serious depressive symptoms among Chinese older adults.

[Ethical issues of oocyte donation].

The birth and development of oocyte donation technology have brought hope for women with poor ovarian reserve and repeated failure for in vitro fertilization, as well as for those with chromosomal abnormalities, premature ovarian failure, or at perimenopausal or menopausal stages. It has not only preserved their reproductive right, but also stabilized their families and increased social harmony. However, this technology does not only involve infertile couples themselves, but also social and ethical issues concerning their families and the society. This paper has reviewed and discussed the hot issues concerning oocyte donation, e.g., source of eggs, compensation for donors, prerequisites for recipients and donors, privacy of donors, and made suggestions for further improvement for the administration of oocyte donation.

Comparison of Pressure- and Volume-Controlled Ventilation in Laparoscopic Surgery: A Meta-analysis of Randomized Controlled Trial.

PURPOSE: Volume-controlled ventilation (VCV) has been the traditional mechanical ventilation mode in laparoscopic surgery. Pressure-controlled ventilation (PCV) has been used more frequently in recent years, especially for patients with complicated conditions; however, evidence on whether PCV is superior to VCV is still lacking. A meta-analysis was used to compare the effects of PCV and VCV on respiratory and hemodynamic parameters during laparoscopic surgery. METHODS: PubMed and Embase were each searched from their inception to December 2014 for randomized controlled trials comparing the effects of PCV and VCV on respiratory and hemodynamic parameters during laparoscopic surgery. Standard mean difference (SMD) with 95% confidence interval (CI) was calculated using a random effect model. Outcomes were assessed at three times: preoperative (T1), intraoperative (T2) and postoperative (T3). Respiratory mechanics (including peak airway pressure, plateau pressure, mean airway pressure, compliance, airway resistance, minute volume, end-tidal CO2 tension and tidal volume) and hemodynamic parameters (including heart rate and mean arterial pressure) were calculated. RESULTS: Eight randomized controlled trials with a total of 428 participants, 214 cases using PCV and 214 cases using VCV, were included in the meta-analysis. No significant differences were detected between the groups in terms of hemodynamic parameters. In contrast, with respiratory mechanics, PCV was slightly but significantly associated with lower peak airway pressure, higher compliance, lower airway resistance at T1, lower peak airway pressure, higher compliance, higher mean airway pressure at T2, lower peak airway pressure, lower mean airway pressure and higher end-tidal CO2 tension at T3. For the rest of respiratory parameters, there were no statistical differences between the groups. Subgroup analysis by morbidly obese, type of operations and quality of studies, showed similar results. CONCLUSIONS: Our meta-analysis suggests that hemodynamic parameters are similar in patients who underwent laparoscopic surgery with PCV and VCV, but patients who had PCV exhibited mildly better respiratory data.

Sleep structure assessed by objective measurement in patients with mild cognitive impairment: A meta-analysis.

OBJECTIVES: A meta-analysis was used to explore the characteristic changes in objective sleep structure of patients with mild cognitive impairment (MCI) compared with cognitively healthy older adults. MATERIALS AND METHODS: PubMed, EMBAS, Cochrane Library, Scopus, and Web of Science were searched until November 2023. A literature quality evaluation was performed according to the Newcastle-Ottawa Scale, and a meta-analysis was performed by RevMan 5.3 software. RESULTS: Fifteen studies with 771 participants were finally included. Compared with normal control groups, patients with MCI had a decreased total sleep time by 34.44 min, reduction in sleep efficiency by 7.96 %, increased waking after sleep onset by 19.61 min, and increased sleep latency by 6.97 min. Ten included studies showed that the patients with MCI had increased N1 sleep by 2.72 % and decreased N3 sleep by 0.78 %; however, there was no significant difference between the MCI and control groups in percentage of N2 sleep. Moreover, Twelve included studies reported the MCI groups had shorter REM sleep of 2.69 %. CONCLUSION: Our results provide evidence of abnormal sleep architecture in patients with MCI. As a "plastic state," abnormal sleep architecture may be a promising therapeutic target for slowing cognitive decline and dementia prevention.

Resourcefulness Among Initial Ischemic Stroke Patients: A Longitudinal Study of 12 Months.

Objective: To explore distinct longitudinal trajectories of resourcefulness among initial ischemic stroke patients from diagnosis to 12 months, and to identify whether sociodemographic factors, disease-related factors, self-efficacy, family function, and social support can predict patterns in the trajectories of resourcefulness. Methods: A prospective longitudinal study was conducted. Initial ischemic stroke patients who met inclusion and exclusion criteria were followed up when still in hospital (Preparing for discharge, Baseline, T1), at 1 month (T2), at 3 months (T3), at 6 months (T4), at 9 months (T5) and 12 months (T6) (±1 week) after discharge. General information, National Institute of Health Stroke Scale (NIHSS), Modified Rankin Scale (mRS), General Self-Efficacy Scale (GSES), General Family Functioning Subscale (FAD-GF), and Social Support Rate Scale (SSRS) were used in T1. The Resourcefulness Scale© was evaluated at 6 time points. Growth mixture modeling was used to identify trajectory patterns of resourcefulness. Logistic regression was used to identify predictors of resourcefulness trajectories. Results: Three longitudinal trajectories of resourcefulness were identified and named as the high-stable class (38.9%, n=71), fluctuation class (41.2%, n=75), and low-stable class (19.9%, n=36), respectively. Dwelling areas (x2=6.805, P=0.009), education (x2=44.865, P=0.000), monthly income (x2=13.063, P=0.001), NIHSS scores (x2=44.730, P=0.000), mRS scores (x2=51.788, P=0.000), Hcy (x2=9.345, P=0.002), GSES (x2=56.933, P=0.000), FAD-GF (x2=41.305, P=0.000) and SSRS (x2=52.373, P=0.000) were found to be statistically significant for distinguishing between different resourcefulness trajectory patterns. Lower education (OR=0.404), higher NIHSS(OR=6.672) scores, and higher mRS(OR=21.418) scores were found to be risk factors for lower resourcefulness, whereas higher education(OR=0.404), GSES(OR=0.276), FAD-GF(OR=0.344), and SSRS(OR=0.358) scores were identified as protective factors enhancing resourcefulness. Conclusion: This study obtained three patterns of trajectories and identified their predictive factors in initial ischemic stroke. The findings will assist health care professionals in identifying subgroups of patients and when they may be at risk of low resourcefulness and provide timely targeted intervention to promote resourcefulness.

A reliability and validity study of the electronic health literacy scale among stroke patients in China.

BACKGROUND: Patients with stroke usually use smartphones to obtain online information to maintain their health. But their ability to identify, evaluate and apply this information is still unknown. AIM: This study was designed to examine the reliability and validity of the electronic Health Literacy Scale among patients with stroke in China. DESIGN: This is a cross-sectional survey. METHODS: A demographic questionnaire, the electronic Health Literacy Scale (e-HLS) and the eHealth Literacy Scale (eHEALS) were administered to a sample of 648 patients with ischemic stroke recruited from December 2020 to March 2021 in a tertiary hospital. RESULTS: The Cronbach'α coefficient on the e-HLS-CHI was 0.907. Kappa consistency coefficient of test-retest reliability was 0.691 (p < .05). Three factors were extracted by Exploratory Factor Analysis (EFA), accounting for 90.84% of the total variance. Confirmatory Factory Analysis (CFA) revealed that three factors of e-HLS-CHI fit well (NFI = 0.979, RFI = 0.955, IFI = 0.987, TLI = 0.972, CFI = 0.987, RMSEA = 0.070, CMIN/DF = 2.586). Good simultaneous validity was suggested by the positive correlation of 0.94 (p < .001) between the e-HLS-CHI and eHEALS. When using eHEALS as the standard, the area under the ROC curve of e-HLS-CHI was 0.896 (95% CI: 0.831-0.960, p < .001). The sensitivity and specificity were 97.8% and 70.4% respectively. CONCLUSIONS: The e-HLS can be used to evaluate electronic health literacy of patients with stroke in China after translation and cultural adaption.

Experiences of health management among people at high risk of stroke in China: A qualitative study.

BACKGROUND: Effective health management of people at high risk of stroke in China is challenging. AIM: To explore and identify the experiences of health management among people at high risk of stroke in order to provide a foundation for a targeted health management strategy for this special group. DESIGN: A qualitative, descriptive study based on interviews. METHODS: Semistructured interviews were conducted with 31 people at high risk of stroke. The interviews were collated and analysed using Colaizzi's seven-step method. RESULTS: A total of 31 people at high risk of stroke were included, and the ages ranged from 40 to 86, with an average age of 60.71 (SD = 11.55). The experiences of health management were categorized into three themes. Theme 1: Facing many ongoing problems in health management, limited knowledge, lack of confidence and poor compliance. Theme 2: Accumulated some value experiences of coping with problems of health management, becoming active learners, promoting social interaction and enhancing self-health management. Theme 3: Sensitivity to multiple influencing factors, the severity of disease and complexity of disease management, family income and economic burden and the value of social support. CONCLUSIONS: This study explored the experiences of health management among people at high risk of stroke, and these findings are of great significance in the primary prevention of stroke.

Effectiveness of health management among individuals at high risk of stroke: An intervention study based on the health ecology model and self-determination theory (HEM-SDT).

Background: Stroke is the second leading cause of death in adults worldwide. However, up to 80% of strokes can be prevented by modifying risk factors. Objective: The study aims to assess the effectiveness of the Health Ecology Model and Self-Determination Theory (HEM-SDT) based health management intervention among individuals at high risk of stroke. Methods: A randomized controlled trial was conducted in Zhengzhou from May 1st, 2020, to December 31st, 2020. A total of 229 participants were recruited for the study, with 116 individuals at high risk of stroke being randomly assigned to the HEM-SDT health management group, while 113 participants were enrolled in the control group, following their current routine practices. The Generalized Estimating Equation model (GEE) was used to analyze the differences in health knowledge, belief and, behavior between the two groups at the beginning of the intervention, and at 6-month intervals after the intervention. The chi-square test was utilized to assess the control rate of risk factors. Results: After 6 months of intervention, there were significant improvements in health knowledge, behavior, and belief among the participants. The study found significant differences in the interaction effects between time and group for health knowledge (Mean, SD = 25.62 ± 3.88, 95%CI: 7.944-9.604, P＜0.001), health belief (Mean, SD = 87.18 ± 14.21, 95%CI: 23.999-29.887, P＜0.001), and health behavior (Mean, SD = 173.28 ± 24.22, 95%CI: 22.332-36.904, P＜0.001). Additionally, the rates of hypertension, hyperglycemia, dyslipidemia, high or medium risk condition of stroke, obesity, hyperhomocysteinemia, smoking, alcohol consumption, and lack of exercise also showed statistical significance (P＜0.05) after the intervention. Conclusion: The HEM-SDT health management model improves the health knowledge, behavior, and beliefs in people at high risk of stroke and remarkably it shows improvement in modifiable risk factors. It can be recommended for systematic health management in people at high-risk of stroke.

Is sleep quality a moderated mediator between perceived stress and depression among stroke patients?

Background: Sleep quality can offer new insights into addressing depression among stroke patients. However, the current understanding of the mechanism by which sleep quality reduces depression is not clear in existing research. Objectives: This study aimed to identify the relationships and mechanisms among perceived stress, sleep quality, social support, and depression in stroke patients. Methods: A multicenter cross-sectional study was conducted from January to May 2023. Cluster random sampling was used to recruit 500 stroke patients from five hospitals in Henan Province, China. The Chinese Perceived Stress Scale (CPSS), Pittsburgh Sleep Quality Index (PSQI), Social Support Rating Scale (SSRS), and Hamilton Depression Scale (HAMD-24) were employed to assess perceived stress, sleep quality, social support, and depression, respectively. Data were analyzed using descriptive analysis, Pearson's correlation analysis, and moderated mediation analysis. The study adhered to the STROBE checklist for reporting. Results: Out of 500 participants, 471 completed the survey (94.2%). After controlling for sex and age, mediation analysis revealed that poor sleep quality partially mediated the relationship between perceived stress and depression (ß = 0.184, 95% CI: 0.110, 0.359). Additionally, social support played a moderating role in the mediation model. Conclusion: This study explained the moderated mediation of sleep quality and social support between perceived stress and depression. It provided a theoretical basis for the development of a sleep quality intervention program for reducing depression among stroke patients.
