Technology-based interventions on burden of older adults' informal caregivers: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: An increasing number of technologies are provided to reduce the burden of older adults' informal caregivers. However, less is known about the effects and the mechanism of technology to work on burden. This review is to evaluate the effectiveness of technology-based interventions (TBI) in alleviating the burden of older adults' informal caregivers and to distinguish its effective mechanism via group disparities. METHODS: A systematic review and meta-analysis of randomized controlled trials studies (RCTs) has been conducted. Web of Science, PubMed, EMBASE, Scopus, CINAHL, PsycINFO, WANFANG, CNKI, CQVIP databases, Cochrane Library Trials, and ClinicalTrials.gov were searched for trial studies and registry in both English and Chinese published from January 1990 to October 2022. Reviewers independently screened the articles and trials, conducted quality assessments, and extracted the data. All processes were guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Risk of bias of the studies was evaluated by the Cochrane Systematic Review Handbook. The meta-analysis was conducted by RevMan 5.13. Subgroup analyses, sensitivity analyses, publication bias were also conducted. RESULTS: A total of 11,095 RCTs were initially screened, and 14 trials representing 1010 informal caregivers were included finally. This review proved TBI effective in reducing caregiving burden older adults. Subgroup analysis showed effects of TBI differed by interventions on control group and medical conditions of care recipients. CONCLUSION: TBI is an effective way to alleviate the burden on informal caregivers of aging people. Interventions for control groups and medical conditions of care-recipients are significant factors in effective interventions. Future researches could include more trials with high-quality or to explore more targeted aging groups, modalities of TBI, or caregiver outcomes. TRIAL REGISTRATION: The review protocol was registered on PROSPERO [CRD42021277865].

The application of simulation methods during the COVID-19 pandemic: A scoping review.

With the outbreak of COVID-19 pandemic, simulation modelling approaches have become effective tools to simulate the potential effects of different intervention measures and predict the dynamic COVID-19 trends. In this scoping review, Studies published between February 2020 and May 2022 that investigated the spread of COVID-19 using four common simulation modeling methods were systematically reported and summarized. Publication trend, characteristics, software, and code availability of included articles were analyzed. Among the included 340 studies, most articles used agent-based model (ABM; n = 258; 75.9 %), followed by the models of system dynamics (n = 42; 12.4 %), discrete event simulation (n = 25; 7.4 %), and hybrid simulation (n = 15; 4.4 %). Furthermore, our review emphasized the purposes and sample time period of included articles. We classified the purpose of the 340 included studies into five categories, most studies mainly analyzed the spread of COVID-19 under policy interventions. For the sample time period analysis, most included studies analyzed the COVID-19 spread in the second wave. Our findings play a crucial role for policymakers to make evidence-based decisions in preventing the spread of COVID-19 pandemic and help in providing scientific decision-makings resilient to similar events and infectious diseases in the future.

Projections of future life expectancy in China up to 2035: a modelling study.

BACKGROUND: To plan social and health services, future life expectancy projections are needed. The aim of this study was to forecast the future life expectancy for mainland China and its provinces. METHODS: Following the same approach as the Global Burden of Disease Study, we used the largest compiled epidemiological and demographic datasets to estimate age-specific mortality and evaluate population data from 1990 to 2019. A total of 21 life expectancy forecasting models were combined by a probabilistic Bayesian model to forecast the life expectancy for mainland China and its provinces in 2035. FINDINGS: The projected life expectancy at birth in mainland China in 2035 is 81·3 years (95% credible interval 79·2-85·0), and there is a high probability that the national goals of improving life expectancy will be achieved (79 years in 2030, and over 80 years in 2035). At the provincial level, women in Beijing have the highest projected life expectancy in 2035 with an 81% probability of reaching 90 years, followed by Guangdong, Zhejiang, and Shanghai, which all have more than a 50% probability of surpassing 90 years. Men in Shanghai are projected to have the highest life expectancy at birth in 2035, with a 77% probability of life expectancy being over 83 years, the highest provincial life expectancy in mainland China in 2019. The projected gains in life expectancy are mainly derived from older individuals (aged ≥65 years), except those in Xinjiang, Tibet, and Qinghai (for men), in which the main contributions come from younger (0-29 years) or middle-aged (30-64 years) individuals. INTERPRETATION: Life expectancy in mainland China and its provinces has a high probability of continuing to increase through to 2035. Adequate policy planning of social and health services will be needed. FUNDING: China National Natural Science Foundation and Social Science Fund of Jiangsu Province.

The Effectiveness of Plaza Dancing on Psychological Well-Being and Ill-Being: A Systematic Review and Meta-Analysis.

Evidence suggests that participation in plaza dancing may affect mental health. This study for the first time quantified the relationships between plaza dancing and psychological well-being and ill-being. We systematically searched PubMed, Web of Science, CNKI, Wanfang, and VIP to identify relevant studies published from the databases since their inception to July 25, 2021. The standardized mean differences (SMDs) of pre-to-post intervention data were calculated in the meta-analysis. Subgroup and meta-regression analyses were performed to test the potential moderating effects of age, outcome classification, measurement instruments, district, publication year, total sample size, and the duration, frequency, and length of the square dance intervention. A total of 25 original articles met all the eligibility criteria and were included in the review, and 17 studies were included in the meta-analysis. The meta-analysis revealed that plaza dancing improved psychological well-being (pooled SMD = 0.76; 95% CI: 0.58, 0.95; I 2 = 86.9%) and reduced psychological ill-being (pooled SMD = -0.84; 95% CI: -1.00, -0.68; I 2 = 64.8%). The study participants' age and district did not seem to affect the effectiveness of the plaza dancing intervention. The duration and frequency of plaza dancing affected the association between square dance and psychological well-being (duration, ß = -0.044; 95% CI: -0.085, -0.004; frequency, ß = 0.122; 95% CI: 0.024, 0.221) and psychological ill-being (duration, ß = -0.029; 95% CI: -0.040, -0.018; frequency, ß = 0.154; 95% CI: 0.030, 0.278). Plaza dancing has a significant positive effect on psychological well-being and psychological ill-being, and the effects are moderated by intervention modality. Generalizing plaza dancing interventions to promote psychological well-being and prevent or treat psychological ill-being is needed.

Trends in depression incidence in China, 1990-2019.

BACKGROUND: Depression is one of the most widespread health burdens for the general population in China. This study aims to assess the long-term trends of depression incidence in China between 1990 and 2019. METHODS: The incidence data were drawn from the Global Burden of Disease Study 2019, and an age-period-cohort model was used in the analysis. RESULTS: The net drift was -0.66% (95% CI: -0.79% to -0.53%) per year for both genders. For males, the local drift was lower than 0 (P<0.05) in those aged 10-54 years, and higher than 0 (P<0.05) in those aged 60-69 years. For females, the local drift was lower than 0 (P<0.05) in those aged 10-49 years and higher than 0 (P<0.05) in those aged 55-84 years. Females had a higher risk of depression incidence than males. Compared with the 1990-1994 period, the relative risk (RR) of depression incidence in 2015-2019 decreased by 12.2% in males and 12.3% in females, and compared to the 1903-1907 birth cohort, the cohort RRs in the 2008-2012 birth cohort decreased by 42.1% in males and 34.5% in females. Period and cohort RRs all showed an increased tendency in recent periods and birth cohorts. LIMITATIONS: These data are macrolevel estimates at the national level, may have ecological fallacies. CONCLUSIONS: Although the age-standard incidence of depression has declined in China as a whole in the last three decades, the incidence of depression among older individuals has increased. More efforts are needed to promote the mental health of elderly individuals in China.

Evidence Based Social Science in China Paper 2: The History and Development of Evidence Based Social Work in China.

OBJECTIVES: To present the history and potential for development of evidence-based (EB) social work in China. STUDY DESIGN AND SETTING: The conception and methodology of EB social work is a potential strategy to support high quality development of social work in China. This article documents and analyzes the progress of EB social work in China. We focus on current research, reasons, challenges, and strategies. RESULTS: EB social work started late in China. The number of EB social work literature and systematic reviews has increased since 2004. The development of EB social work has been uneven nationally with few practitioners and decision makers involved. However, more and more social work researchers received training in evidence-based practice through national workshops and conferences. CONCLUSION: EB social work faced various challenges, but there are now more opportunities for EB social work development in China. Researchers, practitioners, managers and decision makers are encouraged to work together to establish a thorough methodological system and use existing evidence as much as possible when carrying out social work programs and services.

Evidence Based Social Science in China Paper 3: The quality of social science RCTs published from 2000-2020.

OBJECTIVE: This study collected randomized controlled trials (RCTs) published in the social sciences in China and assessed their risk of bias and reporting quality. STUDY DESIGN AND SETTING: Three databases were systematically searched for publications from January 2000 to June 2020 for RCTs in the social sciences published by Chinese researchers. The risk of bias was assessed using the Cochrane Collaboration Risk of Bias Tool, and reporting quality was assessed using the Consolidated Standards of Reporting Trials for Social and Psychological Interventions (CONSORT-SPI). RESULTS: A total of 316 RCTs were identified, including 204 articles in English and 112 articles in Chinese. The most frequently researched interventions focused on education (33.9%), and the most frequently studied population were students (32.9%). Eighty-seven percent of RCTs had intermediate reporting quality. Twenty-four of the 43 CONSORT-SPI sub-items had a compliance rate of less than 50%. Most RCTs had an unclear risk of bias for blinding outcome assessors (84.5%), blinding participants and personnel (82.9%), allocation concealment (73.1%), and random sequence generation (68.0%). A low proportion of CONSORT-SPI items were reported and, high proportion of the papers had unclear risk of bias. CONCLUSION: The quality and reporting of RCTs in the social sciences needs improvement in China, especially for reporting methods and results. Most studies had an unclear risk of bias as they lacked important methodological information.

Evidence Based Social Science in China Paper 4 : The quality of social science systematic reviews and meta-analysis published from 2000-2019.

OBJECTIVES: To examine the characteristics, methodological and reporting quality of systematic reviews and meta-analyses in social science journals in China. STUDY DESIGN AND SETTING: The Chinese Social Sciences Citation Index (CSSCI) databases were searched for systematic reviews and meta-analysis published between January 2000 and December 2019. We randomly selected 200 articles from the 401 identified in our search. The Assessing the Methodological Quality of Systematic Reviews (AMSTAR) and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklists were used to assess the methodological and reporting quality, respectively. RESULTS: The 200 articles we selected covered a wide range of research fields in 9 disciplines, most of which belonged to management, education and psychology. The mean AMSTAR score and PRISMA score was 8.99 ± 3.36 points and 14.74 ± 3.96 points, respectively. These findings indicated that the quality of the systematic reviews was below the average level. Meanwhile, year of publication was related to both methodological quality (P = 0.001) and reporting quality (P < 0.01). CONCLUSION: Although many systematic reviews and meta-analysis have been published in top Chinese journals, the methodological and reporting quality is troubling. Thus, the most urgent task is to increase the standard of systematic reviews and meta-analysis of every discipline rather than continuing to publish them in great quantity.

Impacts of Internet-Based Interventions for Veterans With PTSD: A Systematic Review and Meta-Analysis.

Background: Veterans who did not seek and complete treatment as intended have been shown to have an elevated risk of experiencing and being exposed to post-traumatic stress disorder (PTSD). Internet-based interventions (IBIs) provide more confidentiality and fewer treatment barriers, and they are regarded as potential treatments to reduce PTSD in veterans. However, the effects of IBI for veterans with PTSD are inconclusive. Objectives: IBI is defined as any internet-based series of psychosocial interventions, of which the internet works as a way of delivery. Psychosocial content and reduction of PTSD symptoms in veterans have been recognized as two core elements of this intervention. This study aimed to (1) examine the effects of IBI on veterans' PTSD outcomes and (2) distinguish between the elements of IBI that play an important role for veterans with PTSD. Methods: Web of Science, PubMed, EMBASE, PsycINFO, Cochrane, Wanfang Data, CNKI, and CQVIP databases were searched for randomized controlled trials (RCT) in IBI programs for veterans with PTSD, covering all studies in English and Chinese published from January 1990 to November 2020. Also, related studies tracking citations were identified. Studies met the following inclusion criteria of (1) being RCTs; (2) containing IBI in the full text; (3) having IBI conducted on veterans as participants; and (4) being on PTSD. All processes followed PRISMA. The risk of bias of the studies was assessed by the Cochrane Systematic Review Handbook. The confidence of outcomes of this review was valued according to the GRADE (Grading of Recommendations Assessment, Development, and Evaluation). The meta-analysis was done by RevMan 5.13. Two teams of reviewers independently searched the literature, made the assessment, and extracted the data. Results: A total of 1,493 citations were identified after initial searching, of which the full texts of 66 studies were screened. Eventually, six RCT studies met the inclusion criteria. Beneficial effects of IBI were found on the overall PTSD outcome (-0.29; 95% CI-0.48 to -0.11, p<0.01). Particularly, IBI based on cognitive behavioral therapy (CBT) with peer support was found to be effective for PTSD outcomes (-0.36; 95% CI-0.61 to -0.11, p<0.01). The subgroup analysis demonstrated that scores of PTSD outcome measured by a PCL (PTSD Checklist) decreased to an average score of 0.38 (95% CI -0.60 to -0.15, p=0.001). The intervention had a positive effect on the PTSD outcome on veterans with comorbid psychological disorders (-0.30; 95% CI -0.61 to -0.11, p<0.01). Overall, the six studies included were evaluated with a low risk of bias, and the outcomes of the meta-analysis were proven with high confidence. Conclusion: On the whole, IBIs have a positive effect on the overall PTSD outcome of veterans. The results encouraged us to focus on IBI with CBT with peer support for veterans, on specific instruments for veterans with PTSD, and on veterans with comorbid psychological disorders. This study, however, has limits. Only six studies with a Western population were included, which might result in cultural bias on IBI effects. In future, more high-qualified research and diverse cultural background of RCTs is needed to prove the effectiveness of IBI on veterans with PTSD.

The Effectiveness of Technology-Based Interventions for Reducing Loneliness in Older Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective: To systematically analyze the effectiveness of technology-based interventions for reducing loneliness in older adults. Methods: We searched relevant electronic databases from inception to April 2021, which included Cochrane Library, PubMed, Web of Science, SpringerLink, EMBASE, CNKI, and Wanfang. The following criteria were used: (i) study design-randomized controlled trial (RCT) designs, (ii) people-older adults (aged ≥ 60 years), (iii) intervention-technology-based interventions in which a core component involved the use of technology to reduce loneliness in older adults; and (iv) outcome-reduction of loneliness level in terms of rating scale scores. Two reviewers independently identified eligible studies, extracted data, and assessed the risk of bias in the included studies. A third reviewer resolved any conflicts. The Cochrane Collaboration's bias assessment tool was used to evaluate the risk of bias for the included studies, and Review Manager 5.4 software was used for the meta-analysis. A random effects model was adopted to measure estimates of loneliness reduction, and standard mean differences (SMD) with a 95% confidence interval (CI) were calculated for each intervention-control contrast, and the I2 statistic was applied to examine heterogeneity. Results: A total of 391 participants from six RCTs were included in the review. Of these, three studies were rated as low-quality, and the remaining three were rated as moderate-quality studies. The meta-analysis showed that the evidence regarding the effects on loneliness of technology-based interventions compared with control groups was uncertain, and suggested that technology-based interventions resulted in little to no difference in loneliness reduction compared to control groups (SMD = -0.08, 95% CI -0.33 to 0.17, p = 0.53). Two types of technology-based interventions were identified: smartphone-based video calls and computer-based training with Internet usage. The subgroup analysis found low-quality evidence to support the effectiveness of both intervention types (SMD = -0.01, 95% CI -0.25 to 0.24, p = 0.95, and SMD = -0.38, 95% CI -0.19, 0.64, p = 0.47, respectively). Conclusions: We found no current evidence to support that technology-based interventions were effective compared to different control conditions in reducing loneliness in older adults. This suggests that more research is needed to investigate the effects of technology-based interventions on loneliness in older adults.

Social Technology: An Interdisciplinary Approach to Improving Care for Older Adults.

Population aging is a defining demographic reality of our era. It is associated with an increase in the societal burden of delivering care to older adults with chronic conditions or frailty. How to integrate global population aging and technology development to help address the growing demands for care facing many aging societies is both a challenge and an opportunity for innovation. We propose a social technology approach that promotes use of technologies to assist individuals, families, and communities to cope more effectively with the disabilities of older adults who can no longer live independently due to dementia, serious mental illness, and multiple chronic health problems. The main contributions of the social technology approach include: (1) fostering multidisciplinary collaboration among social scientists, engineers, and healthcare experts; (2) including ethical and humanistic standards in creating and evaluating innovations; (3) improving social systems through working with those who deliver, manage, and design older adult care services; (4) promoting social justice through social policy research and innovation, particularly for disadvantaged groups; (5) fostering social integration by creating age-friendly and intergenerational programs; and (6) seeking global benefit by identifying and generalizing best practices. As an emergent, experimental approach, social technology requires systematic evaluation in an iterative process to refine its relevance and uses in different local settings. By linking technological interventions to the social and cultural systems of older people, we aim to help technological advances become an organic part of the complex social world that supports and sustains care delivery to older adults in need.

Acceptance and Commitment Therapy (ACT) to reduce depression: A systematic review and meta-analysis.

OBJECTIVES: The aim of this study is to investigate the effectiveness of ACT on depression reduction and further examine the relationship between different follow-up periods, different degree of depression, and different age of patients through subgroup analysis. METHODS: Relevant electronic databases were searched from Jan 2010 to Aug 2018, including CNKI, WANFANG, PubMed, EMBASE, Cochrane Library, PsycINFO. Two reviewers independently screened for eligible studies, extracted data, and assessed risk of bias of the included studies. The Cochrane Collaboration's bias assessment tool was used to evaluate the risk of bias for included studies, and Review Manager 5.3 Software for the meta-analysis RESULTS: 18 studies with 1,088 participants were included in the review. Four studies were rated as high-quality studies, and the remaining 14 studies were rated as moderate quality studies. ACT significantly reduced depression as compared with the control group [SMD = 0.59, 95% CI (0.38, 0.81)]. The subgroup analysis found a significant difference between ACT and control group after post-intervention, three months follow up, mild depression group and adults group, [SMD= 0.62, 95% CI (0.35, 0.90), [SMD= 0.55, 95% CI (0.23, 0.87)], [SMD= 0.65, 95% CI (0.40, 0.91)], [SMD= 0.52, 95% CI (0.33, 0.71)] respectively. LIMITATIONS: The heterogeneity between included studies results in heterogeneity of the results. Most of the specific methods for random sequence generation and allocation concealment were not clear. The search results had limitations since only the published studies in Chinese and English were searched and lacked a search for gray and paper documents. CONCLUSIONS: The current study suggested that ACT was significantly for reducing depressive symptoms compared with the control group, especially at three months of follow-up, adult group and mild depression. More research is needed to investigate the difference effects for minor group, moderate and severe depression and long-term follow-up.

Art therapy for anxiety, depression, and fatigue in females with breast cancer: A systematic review.

This systematic review employed a meta-analysis to examine the effectiveness of art therapy for treating anxiety, depression, and fatigue in female patients with breast cancer, the most prevalent cancer and the most common cause of cancer-related mortality among women worldwide. The review included nine original studies and analyzed data from a total of 754 patients. Data extraction and quality assessment were conducted by two independent reviewers. In total, 1,466 articles were retrieved. We excluded studies in which the participant, interventions, and study design did not satisfy the inclusion criteria, leaving nine articles for analysis, The Cochrane risk of bias assessment tools were used for quality evaluation. The analysis revealed a significant difference in treatment outcomes between patients who received art therapy and those who did not (SMD = -0.48, 95%CI [-0.75, -0.21, p = 0.0005]). The review provides initial evidence to suggest that art therapy benefits female breast cancer patients with respect to the treatment of anxiety, depression, and fatigue. However, additional and better-quality studies must be conducted, particularly with larger sample sizes, greater specificity of the design of trials and interventions, and a longer follow-up duration.

Selective admission policy of medical undergraduates in western China: applicants' real attitudes to the choice of a rural medical career.

INTRODUCTION: Since 2010, the Chinese government has been introducing selective admission policy to recruit rural students for 5-year western medicine and traditional Chinese medicine undergraduate education in order to improve rural townships' medical services system in western China. This study aimed to analyse the selective admission policy in western China from the perspective of medical students' attitudes towards rural career choice. METHODS: A cross-sectional survey was conducted and an anonymous questionnaire was used to investigate a sample of medical undergraduates chosen under the selective admission policy. RESULTS: The results indicate that medical undergraduates' enthusiasm to work in rural areas was very limited in Gansu province, western China. Extrinsic motivation played a more important role in rural career choice than intrinsic motivation. The students' attitudes were affected by socioeconomic and cultural conditions, which determined their personal and professional environment. Course major and family economic conditions were associated with their self-decisions. CONCLUSION: Further educational intervention should emphasise the students' humanistic inner qualities and recognition of professional value. Further policy adjustment should considered, for example improving social policy-based regional character and national development strategies.

Association between homocysteine level and the risk of diabetic retinopathy: a systematic review and meta-analysis.

BACKGROUND: Previous studies have demonstrated that elevated homocysteine (Hcy) level represents an independent risk factor for macrovascular disease. However, the relationship between hyperhomocysteinemia and the progression of diabetic retinopathy in patients remains controversial. Hence, the purpose of this systematic review and meta-analysis was to explore any potential association between Hcy and the risk of diabetic retinopathy. METHODS: PubMed, Embase, and the Cochrane Library databases were searched to screen studies that fulfilled the inclusion criteria from date of database inception to November 2017. The summary odds ratio (OR) with 95% confidence intervals (CIs) was used to calculate the pooled effect estimate for the relationship between Hcy and diabetic retinopathy risk. Sensitivity, subgroup analyses, and publication bias were also assessed. RESULTS: Eleven studies involving a total of 2184 diabetic patients were included in the meta-analysis. The summary OR suggested that increased Hcy level in diabetic patients was associated with an increased risk of diabetic retinopathy (OR 1.62; 95% CI 1.29-2.03; p < 0.001). Although significant heterogeneity was detected among the included studies, the findings of sensitivity analysis remained statistically significant. Subgroup analyses found a significant association between Hcy and diabetic retinopathy in most subsets, but no significant association was found if the sample size was < 100, participants had type 1 diabetes mellitus, and the study quality was low. CONCLUSIONS: The findings of this study suggested that elevated Hcy level was associated with an increased risk of diabetic retinopathy, especially in type 2 diabetic patients. This finding may help diabetic patients to achieve effective management strategy to prevent the progression of diabetic retinopathy.

Omega-3 polyunsaturated fatty acids and reduction of depressive symptoms in older adults: A systematic review and meta-analysis.

OBJECTIVE: The aim of this study is to systematically review the efficacy of omega-3 polyunsaturated fatty acid (n-3 PUFA) supplements in reducing depressive symptoms among older adults aged 60 and above. METHODS: Relevant electronic databases were searched from their inception to June 4, 2018, including Medline, Embase, Web of Science, Cochrane Library, PsycINFO, Global Health, CINAHL, ClinicalTrials.gov and Chinese Biomedical Medicine Database. Two reviewers independently screened for eligible studies, extracted data, and assessed risk of bias of the included studies. The effect size data were analyzed using robust variance estimation in meta-regression. RESULTS: Nine studies were included. The overall treatment effects of n-3 PUFA supplements in reducing depressive symptoms for older adults was not statistically significant (d = -0.202, 95% CI = -0.463, 0.060). Meta-regression found interventions with dosage of n-3 PUFA greater than 1.5 g/d had an average effect size of -0.428, with a 95% confidence interval of [-0.822, -0.035], which is statistically significant. Meta-regression did not find significant moderating effects of comorbidity, baseline depression, intervention duration, and EPA-DHA ratio, potentially due to limited statistical power. LIMITATIONS: The current review only included 9 studies based on literature search in major English and Chinese databases, which provided limited statistical power for moderator analysis and the results are suggestive only. CONCLUSIONS: The meta-analysis of 9 RCTs found mixed findings of the efficacy of n-3 PUFA in the treatment of depressive symptoms among older adults aged 60 and above. More high-quality, large-scale RCTs are needed to confirm the current conclusions.

Light therapy for older patients with non-seasonal depression: A systematic review and meta-analysis.

BACKGROUND: Light therapy has become an increasingly common treatment for adults with depression, yet the role of light therapy for non-seasonal depression among older adults remains unclear. OBJECTIVE: This meta-analysis sought to evaluate the effectiveness of light therapy among older patients with non-seasonal depression. METHODS: We searched the Cochrane Central Register of Controlled Trials, PubMed, Embase, Web of Science, CNKI and CBM from the inception of each database to May 2017. Two researchers conducted the literature screening, data extraction, and methodological quality assessment independently. We used the Cochrane Collaboration's bias assessment tool to evaluate the risk of bias for included studies, and Review Manager 5.2.3 Software for the meta-analysis. RESULTS: Six trials with a total of 359 patients were included, and five studies were assessed as being of low risk for bias. We evaluated the effect of light therapy on depression by the reduction of depressive symptoms (SMD = 0.45; 95% CI= [0.14, 0.75]). The subgroup analysis did not find significant moderating effects of depression with intervention intensity, light type, measuring scale or intervention duration. LIMITATIONS: Most of the study samples were not representative of the larger population of adults and therefore caution should be used when interpreting the findings. CONCLUSIONS: Light therapy has a positive effect on geriatric non-seasonal depression. Studies with larger sample sizes are needed to confirm the curative effect of light therapy in the future.

Clinical Practice Guidelines for Hypertension: Evaluation of Quality Using the AGREE II Instrument.

INTRODUCTION: Hypertension is an important public health challenge. The purpose of clinical practice guidelines (CPGs) is to provide explicit recommendations for clinical practice, reduce inadequate variations, optimize results, minimize risks, and promote cost-effective practice. Therefore, a highly methodological quality development process for CPGs is more likely to yield a CPG that contains relevant and appropriate recommendations. METHOD: To assess the quality of CPGs for the prevention and treatment of hypertension, a systematic search was performed using the following literature databases: PubMed, Excerpta Medica Database (EMBASE), Web of Science, the National Guideline Clearinghouse (NGC), Chinese National Knowledge Infrastructure (CNKI), Wan fang Data, VIP, and Chinese Biomedical Literature Database (CBM). Then the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument was used to assess the quality of the CPGs. RESULTS: Forty-one CPGs were identified (ten CPGs in Chinese and 31 CPGs in English). The results for the overall recommendation were as follows: strongly recommended (15 %), recommended (29 %), weakly recommended (51 %), and not recommended (5 %). The scores for all domains (mean ± standard deviations) were "scope and purpose" (58.65 ± 12.67 %), "stakeholder involvement" (48.07 ± 11.41 %), "rigor of development" (27.31 ± 12.29 %), "clarity of presentation" (53.89 ± 11.09 %), "applicability" (40.10 ± 13.33 %), and "editorial independence" (38.75 ± 16.43 %). All differences were statistically insignificant for all domains (P > 0.05) according to publication time. CPGs using an evidence-based (EB) method were of a higher quality than non-EBs for all domains, but the differences were significant for the following domains: "Scope and Purpose," "Rigor of Development," "Applicability," and "Editorial Independence" (P < 0.05). The scores for the CPGs developed based on associations and society appeared slightly higher than those developed by individuals. However, the differences were insignificant for all domains (P > 0.05). CONCLUSION: A more systematic approach for the development and report of these guidelines is recommended. The AGREE II instrument can be a useful tool to improve the quality of guidelines.

Long-term clinical outcomes of everolimus-eluting stent versus paclitaxel-eluting stent in patients undergoing percutaneous coronary interventions: a meta-analysis.

BACKGROUND: Everolimus -eluting stent (EES) is common used in patients undergoing percutaneous coronary interventions (PCI). Our purpose is to evaluate long-term clinical outcomes of everolimus -eluting stent (EES) versus paclitaxel-eluting stent (PES) in patients undergoing percutaneous coronaryinterventions (PCI) in randomized controlled trials (RCTs). METHODS: We searched Medline, EMBASE, Cochrane Library, CNKI, VIP and relevant websites ( https://scholar-google-com.ezproxy.lib.usf.edu/ ) for articles to compare outcomes between everolimus-eluting stent and paclitaxel-eluting stent without language or date restriction. RCTs that compared the use of everolimus -eluting stent and paclitaxel-eluting stent in PCI were included. Variables relating to patient, study characteristics, and clinical endpoints were extracted. Meta-analysis was performed using RevMan 5.2 software. RESULTS: We identified 6 published studies (from three randomized trials) more on everolimus-eluting stent (n = 3352) than paclitaxel-eluting (n = 1639), with follow-up duration ranging from 3, 4 and 5 years. Three-year outcomes of everolimus-eluting stent compared to paclitaxel-eluting were as following: the everolimus-eluting stent significantly reduced all-cause death (relative risk [RR]:0.63; 95% confidence interval [CI]: 0.46. to 0.82), MACE (RR: 0.56; 95% CI: 0.41 to 0.77), MI (RR: 0.64; 95% CI: 0.48 to 0.86), TLR (RR: 0.72; 95% CI: 0.59 to 0.88), ID-TLR (RR: 0.74; 95% CI: 0.59 to 0.92) and ST (RR: 0.54; 95% CI: 0.32 to 0.90). There was no difference in TVR between the everolimus-eluting and paclitaxel-eluting (RR: 0.76; 95% CI: 0.58 to 1.10); Four-year outcomes of everolimus-eluting compared to paclitaxel-eluting: the everolimus-eluting significantly reduced MACE (RR: 0.44; 95% CI: 0.18 to 0.98) and ID-TLR (RR: 0.47; 95 % CI: 0.23 to 0.97). There was no difference in MI (RR: 0.48; 95% CI: 0.16 to 1.46), TLR (RR: 0.46; 95% CI: 0.20 to 1.04) and ST ((RR: 0.34; 95% CI: 0.05 to 2.39). Five-year outcomes of everolimus-eluting stent compared to paclitaxel-eluting: There was no difference in ID-TLR (RR: 0.67; 95% CI: 0.45 to 1.02) and ST (RR: 0.71; 95% CI: 0.28 to 1.80). CONCLUSIONS: In the present meta-analysis, everolimus-eluting appeared to be safe and clinically effective in patients undergoing PCI in comparison to PES in 3-year clinical outcomes; there was similar no difference in reduction of ST between EES and PES in long-term(≥ 4 years) clinical follow-ups. Everolimus-eluting is more safety than paclitaxel-eluting in long-term clinical follow-ups, whether these effects can be applied to different patient subgroups warrants further investigation.
