Objective: This study aims to assess research trends in the association between schizophrenia and autoimmune diseases, systematically review their relationship, and evaluate the credibility of existing evidence. Methods: Bibliometric analysis was conducted using the bibliometrix package in R, along with VOSviewer and CiteSpace. Relevant systematic reviews and meta-analyses were retrieved from six databases: PubMed, Web of Science, Embase, CINAHL, PsycINFO, and the Cochrane Library. Summary risk estimates were recalculated using the DerSimonian and Laird method under a random-effects model, and the credibility of the evidence was assessed. Results: The bibliometric analysis found that "meta-analysis" has become a frequently used keyword and may be a focal point for future research. The umbrella review included 17 articles, containing 24 report data points from 12 quantitative reviews. Results indicated that 9 reports assessed the relationship between schizophrenia and autoimmune diseases. Schizophrenia was significantly associated with autoimmune neurological disorders (RR = 1.42; 95 % CI = 1.18-1.72), providing suggestive evidence. Seven reports evaluated the impact of schizophrenia on autoimmune diseases, showing highly suggestive evidence that schizophrenia patients had a pooled relative risk of 2.22 (95 % CI = 1.95-2.52) for psoriasis. Eight reports assessed the impact of autoimmune diseases on schizophrenia, with bullous pemphigoid patients showing significantly higher schizophrenia prevalence (OR = 2.63; 95 % CI = 2.03-3.39). Conclusions: This study synthesizes evidence of varying levels, highlighting the association between schizophrenia and autoimmune diseases. It offers new insights for future exploration, fosters interdisciplinary collaboration, and provides valuable implications for public health policy development.

Background: The global push to scale up telemedicine services is challenged by complex, multilevel, multifaceted implementation and a lack of consensus on what the evidence-based essential building blocks of implementation are. Objective: We aimed to evaluate the evidence base supporting telemedicine implementation knowledge tools; identify shared conceptual constructs and outliers; and formulate recommendations to guide the design, development, and optimization of telemedicine services. Methods: We conducted implementation research using a rapid umbrella review, that is, an overview of systematic reviews, in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). In total, we searched 3 databases (PubMed, Web of Science, and Scopus) for studies focusing on telemedicine implementation frameworks, models, and tools, collectively referred to as "knowledge tools." Reviews meeting the operational definition of a systematically undertaken, secondary evidence synthesis, such as systematic and scoping reviews, and those published from January 2018 to May 2024 were considered. A meta-aggregative qualitative analysis was undertaken, comprising inductive thematic synthesis. Results: In total, 18 reviews were selected, encompassing 973 primary studies. Global perspectives were reflected in 61% (n=11) of the reviews, while 33% (n=6) focused on low- and middle-income country contexts. The primary research included in the reviews represented 63 countries, spanning the Americas, Europe, Africa, the Middle East, and Asia and the Pacific. Findings indicated substantial heterogeneity across the identified telemedicine implementation theories, models, and frameworks. However, following evidence synthesis, considerable convergence was observed, highlighting a state-of-the-art understanding of the essential requirements for a national telemedicine implementation ecosystem. These were categorized into "process" and "thematic" dimensions. Process dimensions included readiness and needs assessment, road map and planning, managing change, implementing telemedicine services, and continuous improvement and measuring performance. Thematic dimensions covered human and sociocultural aspects; organization, operations, management, and leadership; communication and coordination; policy, legal, and financial considerations; clinical health condition and quality of care; and the wider context. Conclusions: The findings of this study inform a pressing translational research knowledge gap in telemedicine implementation, hindering the implementation of high-quality, sustainable, and scalable telemedicine systems. The study contributes to building global consensus on the state of the art of key constructs in telemedicine implementation and recommends that future research focus on field-testing the evidence-based implementation tools to evaluate their usability and adaptability across diverse telemedicine contexts.

Several systematic reviews support nature-based interventions (NBIs) as a mechanism of enhancing mental health and wellbeing. However, the available evidence for the effectiveness of these interventions is fragmentary and mixed. The heterogeneity of existing evidence and significant fragmentation of knowledge within the field make it difficult to draw firm conclusions regarding the effectiveness of NBIs. This can only limit the development of interventions to support personal and planetary wellbeing, potentially resulting in ineffective and ill-targeted investment decisions. These concerns have hindered the translation of research evidence into practice and guidelines are urgently required to assist researchers, practitioners and policymakers in developing interventions to promote environmental stewardship and meet the health needs of diverse communities. A higher-order or meta-level synthesis is required to make sense of this evidence. This umbrella review synthesises evidence on the barriers and enablers to nature-based interventions through a summative review of existing published systematic reviews and meta-analyses. A systematic search in PsycINFO, PubMed, Greenfile, Web of Science, Embase, Scopus, Academic Search Complete (EBSCO), Environment Complete (EBSCO), Cochrane Library, CINAHL, Health Policy Reference Centre and Google Scholar was performed. This is a mixed method review, and systematic reviews with both quantitative and qualitative data synthesis were included. 64 systematic reviews were included in the synthesis. The descriptive data, extracted from each study, forms an overview of the characteristics of available evidence on nature-based interventions. A narrative synthesis is used to present the potential factors influencing the outcomes of NBIs. The risk of bias of the systematic reviews was assessed using a 16-item Assessment of Multiple Systematic Reviews 2 (AMSTAR2) checklist. Directions for future research, potential quality needs and recommendations for future research, policymaking, and practice are discusssed.

Objective: To summarize the evidence of various exercise modalities on population with insomnia disorders. Method: PubMed, Embase, Cochrane Library, and Web of Science were searched for eligible studies published from inception to October 2022 and updated on September 2023. Systematic reviews with meta -analyses and randomized controlled trials designed to investigate the effect of various exercise modalities on population with insomnia were eligible. Results: A total of 4 SRs with (very) low methodological quality and 1034 participants in 10 network metaanalyses explored the association between different types and intensity exercise modalities with insomnia disorders. Various exercise modalities could significantly improve total sleep time and sleep quality and alleviate insomnia severity. Compared to passive control, moderate aerobic exercise, moderate aerobic exercise combined with light intensity strength and mind -body exercise can improve sleep efficiency and reduce wake after sleep onset by objectively measured. Moderate intensity strength, light intensity strength and mind -body exercise can improve sleep efficiency subjectively measured; mind -body exercise can reduce sleep onset latency and wake time after sleep onset, and increase total sleep time; moderate aerobic exercise can reduce sleep onset latency. Moderate intensity strength, light intensity strength, mind body exercise and moderate aerobic exercise combined with light intensity strength can the severity of insomnia and improv sleep quality. Conclusion: Exercise had a positive effect on relief insomnia and improve sleep quality. Moderate aerobic exercise, mind -body exercise and moderate aerobic exercise combined with light intensity strength play an important role in improving the sleep quality in people with insomnia disorders.

A growing body of literature demonstrated an association between exposure to ambient air pollution and maternal health outcomes with mixed findings. The objective of this umbrella review was to systematically summarize the global evidence on the effects of air pollutants on maternal health outcomes. We adopted the Joanna Briggs Institute (JBI) methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting standards for this umbrella review. We conducted a comprehensive search across six major electronic databases and other sources to identify relevant systematic reviews and meta-analyses (SRMAs) published from the inception of these databases up to June 30, 2023. Out of 2399 records, 20 citations matched all pre-determined eligibility criteria that include SRMAs focusing on exposure to air pollution and its impact on maternal health, reported quantitative measures or summary effects, and published in peer-reviewed journals in the English language. The risk of bias of included SRMAs was evaluated based on the JBI critical appraisal checklist. All SRMAs reported significant positive associations between ambient air pollution and several maternal health outcomes. Specifically, particulate matter (PM), SO2, and NO demonstrated positive associations with gestational diabetes mellitus (GDM). Moreover, PM and NO2 showed a consistent positive relationship with hypertensive disorder of pregnancy (HDP) and preeclampsia (PE). Although limited, available evidence highlighted a positive correlation between PM and gestational hypertension (GH) and spontaneous abortion (SAB). Only one meta-analysis reported the effects of air pollution on maternal postpartum depression (PPD) where only PM10 showed a significant positive relationship. Limited studies were identified from low- and middle-income countries (LMICs), suggesting evidence gap from the global south. This review necessitates further research on underrepresented regions and communities to strengthen evidence on this critical issue. Lastly, interdisciplinary policymaking and multilevel interventions are needed to alleviate ambient air pollution and associated maternal health disparities.

Consumption of ultra-processed foods (UPFs) is associated with various adverse health outcomes, which significantly influence the global disease burden. This umbrella review aimed to fill the knowledge gap and guide public health practices by summarizing the association between UPFs and multiple health outcomes. A total of four databases were systematically searched from inception to December 2022, and 14 eligible systematic re-views (SRs) with meta-analyses (MAs) were identified. The SRs were published in 10 journals from 2020 to 2023, with 54,147-5,750,133 participants and 5-61 studies. The overall corrected covered area (CCA) was corresponded to a slight overlap. The results showed that an increased UPFs consumption is associated with multiple health outcomes (e.g., obesity, diabetes, hypertension, mortality). Only two SRs were "Moderate" regarding the overall methodological quality, while the other twelve were "Low" or "Critically low". Therefore, well-conducted SRs with high-quality prospective cohorts with a particular focus on special populations are needed to verify these findings further.

Objective: To review the effects of shared decision making (SDM) on health outcomes, health care quality, cost, and consultation time METHODS: We conducted an umbrella review and searched systematic reviews on SDM from PubMed, CINHAL, and Web of Science. We included reviews on SDM interventions used in a health care setting with patients. We assessed the eligibility of retrieved articles and evaluated whether the review addressed Consolidated Framework for Implementation Research (CFIR) characteristics. Results: Out of 3678 records, 48 reviews were included. Half of the reviews focused exclusively on RCT studies (n = 21). A little less than half were focused specifically on decision aids (n = 23). Thirty-two reviews discussed CFIR characteristics explicitly or implicitly; the majority of which were specific to intervention characteristics. Reviews tended to cluster around patient populations and tended to be low or critically low to moderate in their quality. Reviews of SDM on health outcomes, health care quality, cost, and consultation time were highly uncertain but often ranged from neutral to positive. Conclusions: We observed that SDM implementation did not typically increase costs or increase consultation time while having some neutral to positive benefits on outcomes and quality for certain populations. Gaps in knowledge remain including better research on the climate where SDM is most effective.

Objective: Elder abuse, an important human rights issue and public health problem, contributes to increased disability and mortality. In the last decades, several reviews have synthesized primary studies to determine its prevalence. This umbrella review aimed to estimate the worldwide overall prevalence rate of elder abuse in the community and care setting. Methods: Following prospective registration at PROSPERO (CRD42021281866) we conducted a search of eight electronic databases to identify systematic reviews from inception until 17 January 2023. The corrected covered area was calculated to estimate the potential overlap of primary studies between reviews. The quality of the selected reviews was assessed using a modified AMSTAR-2 instrument. We extracted data on the prevalence of any type of elder (people aged 60 years old or older) abuse in the community and care setting. Results: There were 16 systematic reviews retrieved between 2007 and 2022, out of which ten captured prevalence globally, three in Iran, one in Turkey, one in China and one in Brazil. The 16 reviews included 136 primary studies in total between 1988 and 2020. The overlapping of studies between reviews was found to be moderate (5.5%). The quality of reviews was low (2, 12.5%) or critically low (14, 87.5%). The estimated range of global prevalence of overall elder abuse was wide (1.1-78%), while the estimations of specific abuse prevalence ranged from 0-81.8% for neglect, 1.1-78.9% for psychological abuse, 0.7-78.3% for financial abuse, 0.1-67.7% for physical abuse, and 0-59.2% for sexual abuse. Conclusions: Although the low quality of the evidence and the heterogeneity of the phenomenon makes it hard to give precise prevalence data, it is without a question that elder abuse is a prevalent problem with a wide dispersion. The focus of attention should shift towards interventions and policymaking to prevent this form of abuse.

This study aimed to comprehensively evaluate the oral health statuses of children and adults within the autism spectrum disorder (ASD) population through an umbrella review approach. The prevalence of dental caries, periodontal disease, and associated variables were investigated across selected studies. A systematic search was conducted across databases including PubMed, Scopus, EMBASE, Science Citation Index, Science Direct, Web of Science, MEDLINE, and Wiley Online Library to identify relevant studies. The assessed variables included dental caries prevalence, periodontal disease prevalence, oral hygiene indicators, and the necessity of dental treatment. The pooled prevalence rates, odds ratios, and standardized mean differences were calculated where applicable. The pooled prevalence of dental caries among ASD individuals ranged from 60.6% to 67.3%, while the periodontal disease prevalence ranged from 59.8% to 69.4%. High rates of dental treatment under general anesthesia were reported. Heterogeneous dental caries and periodontal disease prevalence rates were identified, highlighting the need for collaboration and preventive care. Several studies also reported higher prevalence rates of dental trauma and self-inflicted oral injuries among individuals with ASD. However, the review also identified significant methodological limitations in the included studies, including inconsistency in oral health assessment methods and potential bias. The necessity for targeted policies due to high prevalence rates and the requirement for integrated care systems in high DMFT regions were also observed. The umbrella review synthesized diverse findings, revealing variations in dental caries and periodontal disease prevalence among ASD individuals. This review underscores the need for tailored interventions and policies to address oral health disparities. It highlights the necessity of integrated care systems, methodological improvements, and longitudinal studies to comprehensively address the multifaceted oral health challenges within the ASD population.

Abstract Background: Digital health technologies have expanded tremendously in the last two decades, creating an emerging research and clinical field. They are regarded as cost-effective, and their use in healthcare is prioritized by many countries. However, the constant evolution of these technologies has led to an abundance of related literature. Thus, we conducted an umbrella review to identify and characterize digital supportive care interventions for patients with cancer and their relatives. Methods: A preregistered umbrella review was conducted (PROSPERO registration number CRD42022333110). Five databases were searched (Embase, PsycINFO, PubMed, CINAHL, and the Cochrane Library). To be considered, studies had to be systematic reviews or meta-analyses, be performed on pediatric or adult patients with cancer or survivors or their relatives, report results on web-based or app-based supportive care interventions, and measure psychological, functional, or behavioral variables or quality of life related to cancer. The methodological quality of the studies was assessed using the AMSTAR-2 tool. Findings: Twenty eligible studies were identified. Most of the included studies reported results from adult patients with cancer. Globally, digital interventions were shown to be effective for physical activity in patients with cancer but had mixed results regarding emotional outcomes and quality of life. Additionally, a lack of methodological quality was noted for most of the included reviews. Discussion: Digital supportive care interventions could be an effective tool in cancer care for some outcomes. Recommendations have been formulated for further research in this field using adapted methodologies for the development of digital health interventions.

BACKGROUND: Despite progress in reducing global HIV-related mortality, the decrease in the rate of HIV incidence remains slow. As such, HIV testing remains crucial to the prevention of HIV and its treatment. OBJECTIVE: This review aims to examine the credibility and strength of evidence arising from systematic reviews of psychosocial, behavioral, and epidemiological outcomes associated with different delivery models of voluntary HIV counseling and testing. DESIGN: Overviews of systematic reviews. METHODS: We conducted the umbrella review by searching PubMed, EMBASE, CINAHL, the Cochrane Library, Web of Science, ProQuest, Scopus, PsycINFO, and the reference lists of relevant reviews. Eligible reviews published in English between 1 January 2000 and 9 February 2021, and different reported models of voluntary HIV counseling and testing were considered. Two independent reviewers assessed the reviews for methodological quality, employing the Joanna Briggs Institute critical appraisal checklist for systematic reviews and research syntheses. Evidence from meta-analyses of observational and interventional studies were graded as conclusive, highly suggestive, suggestive, or weak. The extracted data were tabulated and narratively synthesized. RESULTS: A total of 17 review papers were identified, most of which focused on home-based, community-based, and facility-based voluntary HIV counseling and testing. The most studied epidemiological outcomes include uptake of HIV testing, linkage to care and access to treatment. The most frequently reported behavioral outcomes were safe sexual practices of use of contraceptive and frequency of casual sex, while the most studied psychosocial outcome was social norms. Community-based voluntary HIV counseling and testing approaches achieved high uptake rates, linkage to care, improvement in behavioral outcomes of lower frequency of casual sex, fewer multiple sexual partners, and users experienced fewer stigmatizing behavior through the normalization of HIV testing. Facility-based voluntary HIV counseling and testing was found to be acceptable when offered as part of antenatal care. Using the evidence classification criteria, most of the outcomes were presented with suggestive evidence (Class III). CONCLUSION: The integration of facility-based and home-based voluntary HIV counseling and testing services could potentially increase linkage to care. However, there is scope for further high-quality reviews and meta-analyses to provide greater insights into the impacts of different voluntary HIV counseling and testing models on behavioral and psychosocial outcomes in middle-high-income countries. The provision of a combination of these voluntary HIV counseling and testing models is needed to achieve and surpass the 95-95-95 goals by 2030.

BACKGROUND: Mental ill-health presents a major public health problem. A potential part solution that is receiving increasing attention is computer-delivered psychological therapy, particularly during the COVID-19 pandemic as health care systems moved to remote service delivery. However, computerized cognitive behavioral therapy (cCBT) requires active engagement by service users, and low adherence may minimize treatment effectiveness. Therefore, it is important to investigate the acceptability of cCBT to understand implementation issues and maximize potential benefits. OBJECTIVE: This study aimed to produce a critical appraisal of published reviews about the acceptability of cCBT for adults. METHODS: An umbrella review informed by the Joanna Briggs Institute (JBI) methodology identified systematic reviews about the acceptability of cCBT for common adult mental disorders. Acceptability was operationalized in terms of uptake of, dropping out from, or completion of cCBT treatment; factors that facilitated or impeded adherence; and reports about user, carer, and health care professional experience and satisfaction with cCBT. Databases were searched using search terms informed by relevant published research. Review selection and quality appraisal were guided by the JBI methodology and the AMSTAR tool and undertaken independently by 2 reviewers. RESULTS: The systematic searches of databases identified 234 titles, and 9 reviews (covering 151 unique studies) met the criteria. Most studies were comprised of service users with depression, anxiety, or specifically, panic disorder or phobia. Operationalization of acceptability varied across reviews, thereby making it difficult to synthesize results. There was a similar number of guided and unguided cCBT programs; 34% of guided and 36% of unguided users dropped out; and guidance included email, telephone, face-to-face, and discussion forum support. Guided cCBT was completed in full by 8%-74% of the participants, while 94% completed one module and 67%-84% completed some modules. Unguided cCBT was completed in full by 16%-66% of participants, while 95% completed one module and 54%-93% completed some modules. Guided cCBT appeared to be associated with adherence (sustained via telephone). A preference for face-to-face CBT compared to cCBT (particularly for users who reported feeling isolated), internet or computerized delivery problems, negative perceptions about cCBT, low motivation, too busy or not having enough time, and personal circumstances were stated as reasons for dropping out. Yet, some users favored the anonymous nature of cCBT, and the capacity to undertake cCBT in one's own time was deemed beneficial but also led to avoidance of cCBT. There was inconclusive evidence for an association between sociodemographic variables, mental health status, and cCBT adherence or dropping out. Users tended to be satisfied with cCBT, reported improvements in mental health, and recommended cCBT. Overall, the results indicated that service users' preferences were important considerations regarding the use of cCBT. CONCLUSIONS: The review indicated that "one size did not fit all" regarding the acceptability of cCBT and that individual tailoring of cCBT is required in order to increase population reach, uptake, and adherence and therefore, deliver treatment benefits and improve mental health.

OBJECTIVES: The aim of this umbrella review of systematic reviews and meta-analyses was to address workplace violence (WPV) against healthcare workers (HCWs). Several systematic reviews exist in the literature, but the diversity of settings, population considered, and type of violence investigated make it difficult to gain insight and use the vast amount of available data to implement policies to tackle WPV. With this in mind, we conducted an umbrella review of systematic reviews and meta-analyses on WPV against HCWs to examine the global prevalence of the phenomena and its features. STUDY DESIGN AND METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, PubMed, Scopus, and ISI Web of Science were searched for relevant systematic reviews and meta-analyses published in English up to November 2022. Data on authors, year, country, violence type, prevalence (pooled and not), setting, population, and specific considerations were extracted. RESULTS: A total of 32 systematic reviews were included, 19 of which performed a meta-analysis, investigating overall, physical, and non-physical violence. Even considering the variability of the data, the COVID-19 pandemic has exacerbated the scale of the problem. From our review, we found that overall violence prevalence among HCWs was reported to be as high as 78.9%, and nurses working in psychiatric wards were the professionals most impacted. CONCLUSION: In conclusion, this umbrella review revealed a high prevalence of WPV among HCWs, which varies between countries, population subgroups, and detection methods. Strengthening recognition of the problem could lead to appropriate local and international strategies to address it.
