Background: Stroke remains one of the major chronic illnesses worldwide that health care organizations will need to address for the next several decades. Individuals poststroke are subject to levels of cognitive impairment and mental health problems. Virtual reality (VR)-based therapies are new technologies used for cognitive rehabilitation and the management of psychological outcomes. Objective: This study performed a meta-analysis to evaluate the effects of VR-based therapies on cognitive function and mental health in patients with stroke. Methods: A comprehensive database search was performed using PubMed, MEDLINE (Ovid), Embase, Cochrane Library, and APA PsycINFO databases for randomized controlled trials (RCTs) that studied the effects of VR on patients with stroke. We included trials published up to April 15, 2021, that fulfilled our inclusion and exclusion criteria. The literature was screened, data were extracted, and the methodological quality of the included trials was assessed. Meta-analysis was performed using RevMan 5.3 software. Results: A total of 894 patients from 23 RCTs were included in our meta-analysis. Compared to traditional rehabilitation therapies, the executive function (standard mean difference [SMD]=0.88, 95% confidence interval [CI]=0.06-1.70, P=.03), memory (SMD=1.44, 95% CI=0.21-2.68, P=.02), and visuospatial function (SMD=0.78, 95% CI=0.23-1.33, P=.006) significantly improved among patients after VR intervention. However, there were no significant differences observed in global cognitive function, attention, verbal fluency, depression, and the quality of life (QoL). Conclusions: The findings of our meta-analysis showed that VR-based therapies are efficacious in improving executive function, memory, and visuospatial function in patients with stroke. For global cognitive function, attention, verbal fluency, depression, and the QoL, further research is required.

Aim: Diabetic peripheral neuropathy (DPN) is a common, severe microvascular complication of diabetes. Our study was to assess prevalence and risk factors for DPN in subjects with type 2 diabetes from 14 different countries. Methods: A total of 2,733 subjects with type 2 diabetes aged 18–65 years (45.3% men, mean duration of diabetes = 8.8 years) were included to perform this International Prevalence and Treatment of Diabetes and Depression (INTERPRET-DD) study in 14 countries. After a structured questionnaire was used in face-to-face interviews to collect sociodemographic characteristics and medical records of the participating subjects, laboratory tests were carried out for clinical measurement. Depressive symptoms were diagnosed and measured using the Patient Health Questionnaire-9. The potential risk factors for DPN were determined by multilevel mixed-effects logistic regression, accounting for clustering of participants within the country. Robustness of the estimates was assessed by sensitivity analysis. Results: The overall prevalence of DPN across different countries was 26.71%, whereas country-specific prevalences showed considerable variation. Multivariate analysis revealed that duration of diabetes (OR: 1.08 per 1-year increase, 95% CI: 1.06–1.09), poor glycemic control (OR: 1.11 per 1% increase in HbA1c, 95% CI: 1.05–1.18), and history of hypertension (OR: 1.58, 95% CI: 1.18–2.12), cardiovascular disease (OR: 2.07, 95% CI: 1.55–2.78) and depressive symptoms (OR: 1.92, 95% CI: 1.43–2.58) were independently and positively associated with the risk of DPN. Sensitivity analyses including or excluding patients from countries with extreme low or high prevalence of DPN yielded similar estimates in terms of trend and magnitude. Conclusions: This international study illustrates that more than a quarter of individuals with type 2 diabetes developed DPN. The prevalence was positively associated with the duration of diabetes, poor glycemic control, and history of hypertension, cardiovascular disease and depressive symptoms.

Aims: The aims of this study were to assess the effectiveness of self-efficacy-focused education on health outcomes in persons with diabetes and review the strategies employed in the interventions. Background: The traditional educational interventions for persons with diabetes were insufficient to achieve the desired outcomes. Self-efficacy-focused education has been used to regulate the blood sugar level, behaviors, and psychosocial indicators for persons with diabetes. Design: This study is a systematic review and meta-analysis. Methods: Studies on the effectiveness of self-efficacy-focused education in persons with diabetes were searched in six databases from inception until January 2018. The data were extracted and the quality of literature was assessed independently. Review Manager 5.3 was applied for the meta-analysis. Besides, the findings were summarized for narrative synthesis. Results: Sixteen trials with 1,745 participants were included in the systematic review and ten trails with 1,308 participants in the meta-analysis. The meta-analysis for A1C, self-efficacy, self-management behaviors, knowledge, and quality of life (QOL) were represented in four, six, six, three, and three studies, respectively. The findings indicated that self-efficacy-focused education would probably reduce A1C, enhance self-efficacy, regulate self-management behaviors, increase knowledge, and improve the QOL for patients with diabetes. Weak quality studies, limited participants, and heterogeneity hindered the results pooled of the other secondary outcomes of fasting blood glucose, 2-hour plasma glucose, weight, weight circumference, body mass index, plasma lipid profile, and other psychological indicators. Goal setting, self-management skills practicing and recording, peer models, demonstration, persuasion by health providers, and positive feedback were the most commonly used strategies in the interventions. However, physiological/emotion arousal strategies were relatively less applied and varied significantly. Conclusion: Individuals with diabetes may benefit a lot from the self-efficacy-focused education. However, insufficient high-quality studies, short-term follow-up period, relatively deficient physiological/emotion strategies, and incomplete outcome assessments were the drawbacks in most studies. Establishing satisfactory self-efficacy-focused education and better evaluating the effects were required in further studies.
