Objective. Chronological age alone does not adequately reflect the difference in health status of a patient with hypertension. Frailty is closely associated with biological age, and its assessment is clinically useful in addressing the heterogeneity of health status. The purpose of our study is to comprehensively examine the predictive value of frailty for negative health outcomes in hypertensive patients through a systematic review and meta-analysis. Methods. Multiple English and Chinese databases were searched from inception to 04.11.2020. All cross-sectional and longitudinal studies that examined the association between frailty and relevant clinical outcomes among hypertensive patients were included. The NOS was used to assess the risk of bias of studies included in the analysis. Hazard ratios (HRs), odds ratios (ORs), and 95% confidence intervals (CIs) were pooled for outcomes associated with frailty. Results. Six longitudinal studies and one cross-sectional study involving 17403 patients with hypertension were included in the meta-analysis. The risk of bias of all included studies was rated as low or moderate. The pooled HR of frailty related to mortality was 2.45 (95% CI: 2.08-2.88). The pooled HR of prefrailty and frailty-related injurious falls was 1.07 (95% CI: 0.83-1.37) and 1.89 (95% CI: 1.56-2.27), respectively. The pooled HR of prefrailty and frailty-related hospitalization was 1.54 (95% CI: 1.38-1.71) and 1.94 (95% CI: 1.17-3.24), respectively. Conclusions. This systematic review suggests that frailty was a strong predictor of mortality, hospitalization, and injurious falls among patients with hypertension. Our findings indicate that assessment of frailty in patients with hypertension to guide their management may be necessary in clinical setting. However, our finding was based on very limited amount studies; thus, future studies are required to further validate the role of frailty in prediction of negative health outcomes in hypertensive patients as well as pay more attention to the following knowledge gaps: (1) the association between frailty and hypertension-related outcomes, (2) the significance of the association between different frailty models and relevant clinical outcomes, and (3) the predictive value of prefrailty for the negative health outcomes in people with hypertension.

Background: Potentially inappropriate care can result from overuse or underuse of treatments, tests, or procedures. Overuse is defined as the use of health services with no clear benefit to the recipient or where harms outweigh benefits and/or costs of care. Underuse is defined as failure to deliver an effective and cost-effective healthcare intervention. Cardiovascular procedures such as coronary artery bypass grafting, carotid endarterectomy, coronary angiography, and coronary angioplasty (with/without stenting) are potentially both underused and overused. This systematic review aims to identify rates of potential overuse and underuse of these cardiovascular procedures and explore any associated patient or healthcare system factors. Methods: A systematic review and meta-analysis will be conducted in accordance with the PRISMA guidelines. A systematic search of MEDLINE (via Ovid), Embase, Cumulative Index to Nursing and Allied Health Literature and the Cochrane library will be conducted using a predefined search strategy.  Eligible studies for inclusion will examine rates of overuse and underuse of cardiovascular procedures, measured against national/international guidelines, for adults aged ≥18 years. Primary observational studies including cross-sectional and cohort studies will be included. Titles, abstracts, and full texts will be screened for inclusion by two reviewers. Data will be extracted using a standardised form. Risk of bias for all included studies will be assessed using a modified version of the Hoy risk of bias tool. Where adequate data exists, and if statistically appropriate, meta-analyses will be conducted. If statistical pooling of the data is not possible, the findings will be narratively summarised focusing on the review’s objectives. Conclusion: This systematic review will examine overuse and underuse of cardiovascular procedures for adults.  The results will help inform policy makers, researchers, patients, and clinicians in the appropriate use of these procedures, in line with international guidelines. Registration: This protocol has been submitted for registration on PROSPERO (CRD42021239041).

BackgroundSmoking adversely impacts pain-related outcomes of spinal cord stimulation (SCS). However, the proportion of SCS patients at risk of worse outcomes is limited by an incomplete knowledge of smoking prevalence in this population. Thus, the primary aim of this systematic review is to determine the prevalence of smoking in adults with chronic pain treated with SCS.MethodsA comprehensive search of databases from 1 January 1980 to 3 January 2019 was conducted. Eligible study designs included (1) randomized trials; (2) prospective and retrospective cohort studies; and (3) cross-sectional studies. The risk of bias was assessed using a tool specifically developed for prevalence studies. A total of 1619 records were screened, 19 studies met inclusion criteria, and the total number of participants was 10 838.ResultsThirteen studies had low or moderate risk of bias, and six had a high risk of bias. All 19 studies reported smoking status and the pooled prevalence was 38% (95% CI 30% to 47%). The pooled prevalence in 6 studies of peripheral vascular diseases was 56% (95% CI 42% to 69%), the pooled prevalence of smoking in 11 studies of lumbar spine diagnoses was 28% (95% CI 20% to 36%) and the pooled prevalence in 2 studies of refractory angina was 44% (95% CI 31% to 58%).ConclusionsThe estimated prevalence of smoking in SCS patients is 2.5 times greater than the general population. Future research should focus on development, testing and deployment of tailored smoking cessation treatments for SCS patients.

The Impact

IntroductionForgetting to take a medication is the most common reason for non-adherence to self-administered medication. Dose administration aids (DAAs) are a simple and common solution to improve unintentional non-adherence for oral tablets. DAAs can be in the form of compartmentalised pill boxes, automated medication dispensing devices, blister packs and sachets packets. This protocol aims to outline the methods that will be used in a systematic review of the current literature to assess the impact of DAAs on adherence to medications and health outcomes.Methods and analysisRandomised controlled trials will be identified through electronic searches in databases including EMBASE, MEDLINE, CINAHL and the Cochrane Library, from the beginning of each database until January 2020. Two reviewers will independently screen studies and extract data using the standardised forms. Data extracted will include general study information, characteristics of the study, participant characteristics, intervention characteristics and outcomes. Primary outcome is to assess the effects of DAAs on medication adherence. Secondary outcome is to evaluate the changes in health outcomes. The risk of bias will be ascertained by two reviewers in parallel using The Cochrane Risk of Bias Tool. A meta-analysis will be performed if data are homogenous.Ethics and disseminationEthics approval will not be required for this study. The results of the review described within this protocol will be disseminated through publication in a peer-reviewed journal and relevant conference presentations.PROSPERO registration numberCRD42018096087

Prevalence Of Diabetes Mellitus

Introduction: Only 3 types of coronavirus cause aggressive respiratory disease in humans (MERS-Cov, SARS-Cov-1, and SARS-Cov-2). It has been reported higher infection rates and severe manifestations (ICU admission, need for mechanical ventilation, and death) in patients with comorbidities such as diabetes mellitus (DM). For this reason, this study aimed to determine the prevalence of diabetes comorbidity and its associated unfavorable health outcomes in patients with acute respiratory syndromes for coronavirus disease according to virus types. Methods: Systematic review of literature in Pubmed/Medline, Scopus, Web of Science, Cochrane, and Scielo until April of 2020. We included cohort and cross-sectional studies with no restriction by language or geographical zone. The selection and extraction were undertaken by 2 reviewers, independently. The study quality was evaluated with Loney’s instrument and data were synthesized by random effects model meta-analysis. The heterogeneity was quantified using an I2 statistic. Funnel plot, Egger, and Begg tests were used to evaluate publication biases, and subgroups and sensitivity analyses were performed. Finally, we used the GRADE approach to assess the evidence certainty (PROSPERO: CRD42020178049). Results: We conducted the pooled analysis of 28 studies (n = 5960). The prevalence analysis according to virus type were 451.9 diabetes cases per 1000 infected patients (95% CI: 356.74-548.78; I2 = 89.71%) in MERS-Cov; 90.38 per 1000 (95% CI: 67.17-118.38) in SARS-Cov-1; and 100.42 per 1000 (95% CI: 77.85, 125.26 I2 = 67.94%) in SARS-Cov-2. The mortality rate were 36%, 6%, 10% and for MERS-Cov, SARS-Cov-1, and SARS-Cov-2, respectively. Due to the high risk of bias (75% of studies had very low quality), high heterogeneity ( I2 higher than 60%), and publication bias (for MERS-Cov studies), we down rate the certainty to very low. Conclusion: The prevalence of DM in patients with acute respiratory syndrome due to coronaviruses is high, predominantly with MERS-Cov infection. The unfavorable health outcomes are frequent in this subset of patients. Well-powered and population-based studies are needed, including detailed DM clinical profile (such as glycemic control, DM complications, and treatment regimens), comorbidities, and SARS-Cov-2 evolution to reevaluate the worldwide prevalence of this comorbidity and to typify clinical phenotypes with differential risk within the subpopulation of DM patients.

Objective: This review provides the first meta-analysis of the effects of physically active lessons on lesson-time and overall physical activity (PA), as well as health, cognition and educational outcomes. Design: Systematic review and meta-analysis. Six meta-analyses pooled effects on lesson-time PA, overall PA, in-class educational and overall educational outcomes, cognition and health outcomes. Meta-analyses were conducted using the metafor package in R. Risk of bias was assessed using the Cochrane tool for risk of bias. Data sources: PubMed, Embase, PsycINFO, ERIC and Web of Science, grey literature and reference lists were searched in December 2017 and April 2019. Studies eligibility criteria: Physically active lessons compared to a control group in a randomised or non-randomised design, within single component interventions in general school populations. Results: 42 studies (39 in preschool or elementary school settings, 27 randomised controlled trials) were eligible for inclusion in the systematic review and 37 of them were included across the six meta-analyses (n=12,663). Physically active lessons were found to produce large, significant increases in lesson-time PA (d=2.33; 95%CI 1.42, 3.25: k=16) and small, significant effects on overall PA (d= 0.32, 95%CI 0.18, 0.46: k=8). A large, significant effect was shown on lesson-time educational outcomes (d=0.81; 95%CI 0.47, 1.14: k=7) and a small, significant effect on overall educational outcomes (d=0.36, 95%CI [0.09, 0.63], k=25). No effects were seen on cognitive (k=3) or health outcomes (k=3). 25/42 studies had high risk of bias in at least 2 domains. Conclusion: In elementary and preschool settings, when physically active lessons were added into the curriculum they had a positive impact on both physical activity and educational outcomes. These findings support policy initiatives encouraging the incorporation of physically active lessons into teaching in elementary and preschool settings.

Risky Sexual Behaviours

IntroductionThe use of social networks has been increasing worldwide. Mobile websites and applications (apps) allow people to network more quickly and have more partners for sex. This can facilitate risky sexual behaviours, such as having multiple partners and unprotected sex, which can lead to a higher incidence of sexually transmitted infections. This systematic review/meta-analysis will assess the effects of the use of dating sites and apps by women on their level of engagement in risky sexual behaviours and their incidence of sexually transmitted infections.Methods and analysisThe Cochrane Central Controlled Trials Registry, ClinicalTrials.gov, MEDLINE, Embase, SciELO, Web of Science, Scopus and Cumulative Index to Nursing & Allied Health Literature will be searched for cross-sectional studies, clinical trials and observational studies published between January 1990 and July 2020. This systematic review and meta-analysis will include studies investigating the use of mobile apps by women, risky sexual behaviour and sexually transmitted infections. The outcome will be an increase in new cases of sexually transmitted infections and HIV among women using dating sites and apps. Three independent reviewers will select the studies and extract data from the original articles. The risk of bias will be assessed using the Cochrane risk of bias tool and Risk Of Bias in Non-randomized Studies of Interventions. Data synthesis will be performed using Review Manager software (RevMan V.5.2.3). To assess heterogeneity, we will compute the I2 statistic. In addition, a quantitative synthesis will be carried out if the included studies are sufficiently homogeneous.Ethics and disseminationThis study will be a review of the published data, and thus ethical approval is not required. The findings of this systematic review will be published in a peer-reviewed journal.PROSPERO registration numberCRD42019120494.

Objectives: To synthesise existing evidence for the diagnostic accuracy of chest radiographs to detect lung malignancy in symptomatic patients presenting to primary care. Methods: A systematic review was performed and reported in accordance with the PRISMA framework, using a protocol prospectively registered with the PROSPERO database (CRD42020212450). Nine databases were searched for relevant studies. Data were extracted and chest radiograph sensitivity and specificity calculated where possible. Risk of bias was assessed using a validated tool. Random effects meta-analysis was performed. Results: Ten studies were included. Sensitivity meta-analysis was performed in five studies which were not the high risk of bias, with summary sensitivity of 81% (95% CI: 74–87%). Specificity could be calculated in five studies, with summary specificity of 68% (95% CI: 49–87%). Conclusions: The sensitivity of chest radiographs for detecting lung malignancy in primary care is relatively low. Physicians and policymakers must consider strategies to attenuate the possibility of false reassurance with a negative chest radiograph for this significant pathology. Options include widening access to cross-sectional imaging in primary care; however, any intervention would need to take into account the medical and financial costs of possible over-investigation. Prospective trials with long-term follow-up are required to further evaluate the risks and benefits of this strategy. Advances in knowledge: The chest radiograph has a sensitivity of 81% and specificity of 68% for lung malignancy in a symptomatic primary-care population. A negative chest radiograph does not exclude lung cancer, and physicians should maintain a low threshold to consider specialist referral or cross-sectional imaging.

This systematic review and meta-analysis aimed to investigate a possible association between stress and bruxism in humans. This study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines under the code CRD42020188862, and the searches were performed on the following databases: PubMed, Scopus, Web of Science, Cochrane, LILACS, OpenGrey, and Google Scholar. This systematic review evaluated observational studies in adult humans with and without stress to verify the association between bruxism and the presence of stress. The risk of bias was evaluated through the Joanna Briggs Institute Critical Appraisal Tools for Analytical Cross-Sectional Studies. In quantitative analysis, the Odds Ratio (OR) and their 95% confidence interval (CI) were calculated through a fixed-effect model. Furthermore, a summary of the overall strength of evidence was presented using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). A total of 1,458 studies were identified, and six were included in this systematic review. Two studies included were classified with a low risk of bias, and the others were classified with a moderate risk of bias. In three articles, a meta-analysis was performed and showed an association between these two factors (OR 2.07 [1.51, 2.83], p < 0.00001, I2 = 45%). Besides that, a low certainty of the evidence was detected among this association. Stressed individuals show a higher chance of presenting bruxism when compared to healthy individuals. Despite the low heterogeneity found in the quantitative analysis among the articles reporting an association between stress and bruxism, further studies with similar methods are necessary to understand this relationship better.

IntroductionDry eye is a multifactorial chronic condition characterised by tear film insufficiency and instability, and ocular symptoms including foreign body sensation, itching, irritation, soreness and visual disturbance. The prevalence and incidence of dry eye are major determinants of the magnitude of economic and societal costs of the disease. This protocol proposes a systematic review and meta-analysis of the prevalence and incidence of dry eye in the USA.Methods and analysisWorking with an information specialist, we will develop search strategies for Ovid Medline and Embase for population-based cross-sectional and cohort studies involving US-based populations that report the prevalence and/or incidence of dry eye. We will include studies involving persons of all ages from 1 January 2010 to the current date with no language restrictions. We will also hand-search references of included studies, dry eye epidemiology-related systematic reviews, clinical practice guidelines and literature provided by agencies and organisations. Two investigators will independently screen the titles and abstracts, and then full-text reports to determine eligibility. One investigator will extract study data and perform risk of bias assessments using tools designed specifically for prevalence and incidence studies. A second investigator will verify all extracted study data and risk of bias assessments. We will assess heterogeneity, qualitatively and quantitatively. When appropriate, we will meta-analyse prevalence and incidence estimates.Ethics and disseminationThis review does not require approval by an ethics committee because it will use published studies. We will publish our results in a peer-reviewed journal and present at relevant conferences.PROSPERO registration numberCRD42021256934.
