Meta-Analysis Review
PURPOSE
This review aimed to estimate the prevalence of computer vision syndrome (CVS) in the general population and subgroups.
METHODS
A search was conducted in the following the databases: PubMed, SCOPUS, EMBASE, and Web of Science until February 13, 2023. We included studies that assessed the prevalence of CVS in any population. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the methodological quality. A meta-analysis of the prevalence of CVS was done using a random-effects model, assessing the sources of heterogeneity using subgroup and meta-regression analyses.
RESULTS
A total of 103 cross-sectional studies with 66 577 participants were included. The prevalence of CVS was 69.0% (95% CI: 62.3 to 75.3; I: 99.7%), ranging from 12.1 to 97.3% across studies. Point prevalence was higher in women than in men (71.4 vs. 61.8%), university students (76.1%), Africa (71.2%), Asia (69.9%), contact lens wearers (73.1% vs. 63.8%) in studies conducted before the COVID-19 pandemic (72.8%), and in those that did not use the CVS-Q questionnaire (75.4%). In meta-regression, using the CVS-Q scale was associated with a lower prevalence of CVS.
CONCLUSION
Seven out of ten people suffer from CVS. Preventive strategies and interventions are needed to decrease the prevalence of this condition which can affect productivity and quality of life. Future studies should standardize a definition of CVS.

Review
BACKGROUND
As we face the largest refugee crisis since World War Two, research is increasingly examining the impact of forced displacement. The risk of non-affective psychosis in refugees is evidenced to be significantly greater than non-refugees, and the role of pre-, peri- and post-migratory trauma and dissociation is increasingly implicated.
AIMS
To determine the prevalence of non-affective psychosis in refugee populations.
METHOD
PRISMA guidelines were followed. Three key databases (PubMed, PsychINFO and Web of Science), Google scholar and study references were searched. The full-text of 62 studies were screened and 23 studies were eligible for inclusion. A narrative synthesis was undertaken and the Quality Assessment Tool for Quantitative Studies was used to assess methodological quality. (PROSPERO registration CRD42019152170).
RESULTS
The results were widely heterogeneous. The combined weighted average prevalence of non-affective psychosis in refugee populations was 0.9 %. Psychosis prevalence for individual psychotic symptoms was 28.4 %; 0.5 % for schizophrenia; 1.0 % for psychosis; 0.6 % for mixed psychotic disorders and 2.9 % for psychotic episodes.
CONCLUSIONS
Variations in examined populations, diagnostic and prevalence classifications, and study designs and methodologies likely contributed to heterogeneity across the data. The findings highlight a greater need to provide more specialist mental health services and trauma-focused interventions, as well as transculturally sensitive assessment and treatment to address refugee vulnerability to psychosis. Future research should examine psychosis prevalence longitudinally and in refugees-only, address methodological bias and further examine the role of trauma and dissociation in refugee psychosis prevalence.

Meta-Analysis Review
Autistic individuals are at an increased risk of experiencing victimisation. Previous reviews have focussed specific types of victimisation. Thus, a clearer picture considering the range of victimisation experiences autistic people face is required. This systematic review aims to identify the prevalence of victimisation in autistic individuals considering a variety of victimisation types (e.g., bulling, sexual victimisation, and crime) in both adults and children from clinical and community settings. Through systematic searches of relevant databases, 291 studies met the criteria for review. Of those, 34 studies met the inclusion criteria: a) quantitative studies, b) involving autistic individuals, c) reporting prevalence rates of victimisation. Meta-analysis found a pooled prevalence rate of victimisation of 44% in autistic individuals. Subgroup analysis examined moderating factors as high heterogeneity was present. This found the pooled prevalence rates for bullying to be 47%, 16% for child abuse, 40% for sexual victimisation, 13% for cyberbullying, and 84% for multiple forms of victimisation in autistic individuals, though heterogeneity remained. Correction for participants' age, reporter used, and the population which the sample was recruited from did not reduce heterogeneity. Although heterogeneity impedes the definitive interpretation of the findings, this review illustrates the need for strategies and interventions to reduce the incidence of victimisation.

Meta-Analysis
IMPORTANCE
Anxiety disorders are associated with poor maternal and neonatal outcomes. Women in low- and middle-income countries (LMICs) are thought to be disproportionally burdened by these disorders, yet their prevalence is unclear.
OBJECTIVE
To conduct a systematic review and meta-analysis to determine the prevalence of 6 anxiety and related disorders among perinatal women in LMICs.
DATA SOURCES
Embase, MEDLINE, PsycINFO, Cochrane Library, CINAHL, and Web of Science databases were searched from inception until September 7, 2023.
STUDY SELECTION
Studies conducted in World Bank-defined LMICs and reporting prevalence of generalized anxiety disorder, obsessive-compulsive disorder, social anxiety disorder, posttraumatic stress disorder, panic disorder, or adjustment disorder during the perinatal period (conception to 12 months post partum) using a validated method were included.
DATA EXTRACTION AND SYNTHESIS
This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. Study eligibility, extracted data, and risk of bias of included studies were assessed by 2 independent reviewers. Random-effects meta-analysis was used to estimate pooled point prevalence. Subgroup analyses were performed by specific anxiety disorder.
MAIN OUTCOMES AND MEASURES
Main outcomes were prevalence estimates of each anxiety disorder, measured as percentage point estimates and corresponding 95% CIs.
RESULTS
At total of 10 617 studies were identified, 203 of which met the inclusion criteria and reported the outcomes of 212 318 women from 33 LMICs. Generalized anxiety disorder was the most reported (184 studies [90.6%]) and most prevalent disorder at 22.2% (95% CI, 19.4%-25.0%; n = 173 553). Posttraumatic stress disorder was the second most prevalent (8.3%; 95% CI, 5.0%-12.2%; 33 studies; n = 22 452). Adjustment disorder was least prevalent (2.9%; 95% CI, 0.0%-14.1%; 2 studies; n = 475). The prevalence of generalized anxiety varied by country income status, with the highest prevalence among lower-middle-income countries (27.6%; 95% CI, 21.6%-33.9%; 59 studies; n = 25 109), followed by low-income (24.0%; 95% CI, 15.3%-33.8%; 11 studies; n = 4961) and upper-middle-income (19.1%; 95% CI, 16.0%-22.4%; 110 studies; n = 138 496) countries.
CONCLUSIONS AND RELEVANCE
These findings suggest that 1 in 5 women living in LMICs experience anxiety disorders during pregnancy and post partum. Targeted action is needed to reduce this high burden.

Meta-Analysis
OBJECTS
To estimate the prevalence and associated factors of vitamin D deficiency (VDD) after Roux-en-Y gastric bypass (RYGB).
METHODS
PubMed, EMBASE, and CENTRAL were searched for relevant records from inception to 17 March 2023, using search terms: vitamin D, vitamin D3, vitamin D deficiency, hypovitaminosis D, gastric bypass, and RYGB. Studies were eligible for inclusion if they provided related data on VDD prevalence after RYGB.
RESULTS
Of the 1119 screened studies, 72 studies involving 7688 individuals were enrolled in the final analysis. The prevalence estimates of VDD after RYGB were 42%. Subgroup analyses suggested the pooled prevalence of postoperative VDD was 35% for follow-up duration less than or equal to 1 year, 43% for greater than 1 and less than or equal to 5 years, and 54% for greater than 5 years. Meta-regression showed that VDD prevalence was positively correlated with follow-up time. Also, the prevalence was higher in studies with inadequate vitamin D supplementation than in those with adequate supplementation and in Asia population than in those from South America, Europe, and North America. Other factors associated with high VDD prevalence after RYGB included high presurgical VDD prevalence, noncompliant patients, and black populations. No significant association existed between VDD and alimentary length.
CONCLUSION
VDD presented a high prevalence in patients following RYGB. It occurred more frequently with longer postoperative follow-up time. Population-specific vitamin D supplementation measures, targeted treatment for presurgical VDD, improved patient compliance, and periodical follow-ups were necessary to reduce VDD and other adverse outcomes.

Meta-Analysis
To estimate the prevalence of carpal tunnel syndrome (CTS) among dental surgeons and the effect of possible moderators on it. A systematic literature search (Medline and Scopus databases) was conducted independently by two reviewers. Only observational studies that examined specifically the prevalence rates of CTS among dentists were included. Quality assessment was performed. The pooled prevalence with 95% confidence intervals (CI) was estimated. Outlier and influential analysis were conducted. Moderator analysis was performed in order the effect of categorical and continuous variables on the estimated prevalence to be investigated. In total, ten eligible studies (3,547 participants) were finally included in this meta-analysis. Two of them were estimated as high quality (low risk of bias) and the remaining ones as moderate quality (moderate risk of bias). The overall prevalence of CTS among dental surgeons was estimated as 9.87% (95%CI 6.84%-14.03%) with significant heterogeneity between studies. No study was identified as influential. Potential sources of heterogeneity were not identified through meta-regression analysis. In the subgroup analysis the prevalence was 12.47% (95%CI 6.38%-22.95%) for the group identified as having CTS through medical history and at least clinical examination or electrodiagnostic testing and 8.56% (95%CI 5.53%-13.01%) among those who identified solely through questionnaire. Our findings are important to provide the pooled prevalence of CTS among dentists. Our results were based on highly heterogeneous studies. Our study reports a considerable prevalence, consequently, significance of awareness among dental surgeons regarding the etiology of this issue is more than necessary. More studies need to be conducted that could guide researchers in order this issue to be fully investigated.

Meta-Analysis Review
BACKGROUND
Violence against children can have extensive, long-term, and far-reaching adverse impacts on survivors and society. There is currently little consensus in the United Kingdom around the prevalence of violence against children: maltreatment, intimate partner violence, sexual violence, bullying, and community violence, and most existing studies focus on only a single or a few forms of violence. This study aims to produce data to highlight the current magnitude of the problem in the UK, to inform policy, drive action and allow for monitoring of progress over time.
OBJECTIVE
To produce weighted prevalence estimates by violence type, as well as gender and age sub-categories, to give as full a picture as possible of the current prevalence of violence against children in the UK.
PARTICIPANTS AND SETTING
The prevalence of violence against children from 23 self-report studies conducted in the United Kingdom was gathered through a systematic review.
METHODS
Databases were searched from inception to 24th June 2022. Studies were reviewed systematically for appropriate data and meta-analyses were conducted to give pooled prevalence data based on a quality effects model.
RESULTS
The most prevalent self-reported experience of childhood violence was community violence at 27.33 % (95 % CI [9.84, 48.97]). Prevalence of bullying was also high at 22.75 % (95 % CI [13.25, 33.86]). The most prevalent forms of child maltreatment were domestic violence exposure at 11.9 % (95 % CI [6.34, 18.84]) and emotional maltreatment at 11.84 % (95 % CI [5.58, 19.89]).
CONCLUSION
National child maltreatment surveys are needed in the UK, using a comprehensive and conceptually robust approach, and valid and reliable instruments, to provide data for researchers and policymakers on the prevalence of all types of violence against children including exposure to multiple types. This allows monitoring of trends over time, can inform strategies for prevention, and can enable monitoring of future progress in reducing violence against children and its associated health and economic burden.

Meta-Analysis
OBJECTIVES
The coronavirus disease-19 (COVID-19) increased the already heavy workload in the pulmonary and respiratory departments, which therefore possibly increased the prevalence of burnout among pulmonologists or respiratory therapists. We aimed to compare the differences in burnout among pulmonologists or respiratory therapists pre- and post-COVID-19 by doing a systematic review with meta-analysis.
METHODS
We searched pulmonologist, or pulmonary, or respiratory, and burnout up to 29 January 2023 in six databases. We included studies investigating pulmonologists or respiratory therapists and reporting the prevalence of burnout among them. The risk of bias was assessed by a tool for prevalence studies. The overall prevalence of burnout was pooled.
RESULTS
A total of 2859 records were identified and 16 studies were included in the final analysis. The included studies reported 3610 responding individuals and 2336 burnouts. The pooled prevalence of burnout was 61.7% (95% confidence interval (CI), 48.6-73.2%; = 96.3%). The pooled prevalence of burnout during COVID-19 was significantly higher than it was prior to the outbreak (68.4% vs. 41.6%, = .01). The result of the meta-regression revealed that COVID-19 coverage was significantly associated with the prevalence of burnout ( = .04).
CONCLUSIONS
Burnout was widely prevalent among pulmonologists or respiratory therapists and increasingly perceived during COVID-19. Therefore, interventions were needed to reduce burnout in this specialty.KEY MESSASGESThe coronavirus disease-19 increased the already heavy workload in the pulmonary and respiratory departments.Burnout was widely prevalent among pulmonologists or respiratory therapists and increasingly perceived during COVID-19.

Meta-Analysis Review
Neurogenic pulmonary edema (NPE) is a life-threatening and severe complication in patients with spontaneous subarachnoid hemorrhage (SAH). The prevalence of NPE varies significantly across studies due to differences in case definitions, study populations, and methodologies. Therefore, a precise estimation of the prevalence and risk factors related to NPE in patients with spontaneous SAH is important for clinical decision-makers, policy providers, and researchers. We conducted a systematic search of the PubMed/Medline, Embase, Web of Science, Scopus, and Cochrane Library databases from their inception to January 2023. Thirteen studies were included in the meta-analysis, with a total of 3,429 SAH patients. The pooled global prevalence of NPE was estimated to be 13%. Out of the eight studies (n = 1095, 56%) that reported the number of in-hospital mortalities of NPE among patients with SAH, the pooled proportion of in-hospital deaths was 47%. Risk factors associated with NPE after spontaneous SAH included female gender, WFNS class, APACHE II score ≥ 20, IL-6 > 40 pg/mL, Hunt and Hess grade ≥ 3, elevated troponin I, elevated white blood cell count, and electrocardiographic abnormalities. Multiple studies showed a strong positive correlation between the WFNS class and NPE. In conclusion, NPE has a moderate prevalence but a high in-hospital mortality rate in patients with SAH. We identified multiple risk factors that can help identify high-risk groups of NPE in individuals with SAH. Early prediction of the onset of NPE is crucial for timely prevention and early intervention.

Meta-Analysis
OBJECTIVE
To estimate the prevalence and risk factors associated with tuberculosis (TB) among people living with human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS) in China.
METHODS
A systematic review and meta-analysis were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. After the literature was screened based on the inclusion and exclusion criteria, STATA version 17.0 software was used for the meta-analysis. The heterogeneity among study data was assessed using I statistics. Subgroup analysis and meta-regressions were performed to further explore the source of heterogeneity.
RESULTS
A total of 5241 studies were retrieved. Of these, 44 studies were found to be eligible. The pooled prevalence of HIV/TB co-infection was 6.0%. The risk factors for HIV/TB co-infection included a low CD4 T cell count, smoking, intravenous drug use and several other sociodemographic and clinical factors. Bacillus Calmette-Guérin (BCG) vaccination history was a protective factor.
CONCLUSION
A high prevalence of TB was observed among people living with HIV/AIDS in China. Low CD4 T cell count, smoking, and intravenous drug use were the primary risk factors for HIV/TB co-infection, whereas BCG vaccination history was a protective factor. Checking for TB should be prioritized in HIV screening and healthcare access.
