Review
BACKGROUND
Back pain, such as upper and low back pain are among the most common musculoskeletal conditions that can cause major public health and socioeconomic problems. Back pain is one of the leading causes of disability that reduces worker performance and well-being and increases absence from work, which can cause an enormous economic burden. In developing countries, particularly in Ethiopia, there is no adequate evidence on the overall prevalence of occupational-related upper and low back pain, and they remain less prioritized and empirically unrepresented. Therefore, this study aimed to determine the prevalence of occupational-related upper and low back pain among the working population of Ethiopia.
METHODS
This systematic review and meta-analysis considered studies conducted in Ethiopia, written in English, and published from 2017 to 2020. Articles were searched from 9 electronic databases (Web of Science, SCOPUS, PubMed, Google Scholar, CINAHL, Cochrane Library, African Index Medicus, African Journals Online database, and Science Direct) using a combination of Boolean logic operators, Medical Subject Headings, and main keywords. The quality assessment of the articles was performed using the Joanna Briggs Institute Critical Appraisal tools to determine the relevance of the articles to the study. A random effects model was used to estimate the pooled prevalence, the 95% confidence interval, and the degree of heterogeneity among the included studies. Sensitivity analyses were performed to identify the influence of outliers and to identify sources of heterogeneity.
RESULTS
Of the 1114 studies identified from the included databases, 20 studies were included in the systematic review and meta-analysis. The pooled prevalence of occupational-related upper and low back pain in the previous year was (27.1% [95% CI: 18.4, 37.9]) and (54.2% [95% CI: 48.2, 60.0]), respectively. Based on a subgroup analysis by publication year, study population, and regions where the studies were conducted, the prevalence of upper back pain was (43.8% [95% CI: 39.3, 47.7]), (34.7% [95% CI: 33.1, 36.2]), and (36.2% [95% CI: 33.6, 39.0]), respectively, while the prevalence of low back pain was (61.8% [95% CI: 58.9, 64.6], (52.8% [95% CI: 51.3, 54.3]), and (55.2% [95% CI: 51.4, 59.0]), respectively.
CONCLUSIONS
This systematic review and meta-analysis found that 54.2% of the included study participants experienced low back pain in the previous year, while 27.1% experienced upper back pain. The highest prevalence was reported among pedestrian back-loading women.

Meta-Analysis
BACKGROUND
Vaginal birth after caesarean section (VBAC) is an alternative to a caesarean section (CS) in the absence of repeat or new indications for primary CS. There is a knowledge gap regarding the trend and successful VBAC in Ethiopia. Therefore this systematic review and meta-analysis aimed to assess the trend, pooled prevalence of successful VBAC and its predictors in Ethiopia.
METHODS
Electronic databases (SCOPUS, CINAHL, Embase, PubMed and Web of Science), Google Scholar and lists of references were used to search works of literature in Ethiopia. Stata version 14 was used for analysis and the odds ratios of the outcome variable were determined using the random effects model. Heterogeneity among the studies was assessed by computing values for I2 and p-values. Also, sensitivity analyses and funnel plots were done to assess the stability of pooled values to outliers and publication bias, respectively.
RESULTS
A total of 12 studies with a sample size of 2080 were included in this study. The overall success rate of VBAC was 52% (95% confidence interval 42 to 65). Cervical dilatation ≥4 cm at admission, having a prior successful vaginal delivery and VBAC were the predictors of successful VBAC.
CONCLUSIONS
Meta-analyses and sensitivity analyses showed the stability of the pooled odds ratios and the funnel plots did not show publication bias. The pooled prevalence of successful VBAC was relatively low compared with existing evidence. However, the rate was increasing over the last 3 decades, which implies it needs more strengthening and focus to decrease maternal morbidity and mortality by CS complications. Promoting VBAC by emphasizing factors favourable for its success during counselling mothers who previously delivered by CS to enhance the prevalence of VBAC.

Meta-Analysis
BACKGROUND AND PURPOSE
Robotic-assisted total knee arthroplasty (RATKA) is an alternative surgical treatment method to conventional total knee arthroplasty (COTKA) that may deliver better surgical accuracy. However, its impact on patient outcomes is uncertain. The aim of this systematic review of randomized controlled trials (RCTs) is to evaluate whether RATKA could improve functional and radiological outcomes compared with COTKA in adult patients with primary osteoarthritis of the knee.
METHODS
We searched Ovid MEDLINE, EMBASE, Scopus, and the Cochrane Library to identify published RCTs comparing RATKA with COTKA. 2 reviewers independently screened eligible studies, reviewed the full texts, assessed risk of bias using the Risk of Bias 2.0 tool, and extracted data. Outcomes were patient-reported outcomes, range of motion, and mechanical alignment (MA) deviation and outliers, and complications.
RESULTS
We included 12 RCTs involving 2,200 patients. RATKA probably results in little to no effect on patient-reported outcomes (mean difference (MD) in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score of -0.35 (95% confidence interval [CI] -0.78 to 0.07) and range of motion (MD -0.73°; CI -7.5° to 6.0°) compared with COTKA. However, RATKA likely results in a lower degree of MA outliers (risk ratio 0.43; CI 0.27 to 0.67) and less deviation from neutral MA (MD -0.94°; CI -1.1° to -0.73°). There were no differences in revision rate or major adverse effects associated with RATKA.
CONCLUSION
Although RATKA likely results in higher radiologic accuracy than COTKA, this may not be clinically meaningful. Also, there is probably no clinically important difference in clinical outcomes between RATKA and COTKA, while it is as yet inconclusive regarding the revision and complication rates due to insufficient evidence.

Meta-Analysis
IMPORTANCE
Considerable controversy exists regarding the best spontaneous breathing trial (SBT) technique to use.
OBJECTIVE
To summarize trials comparing alternative SBTs.
DATA SOURCES
Several databases (MEDLINE [from inception to February 2023], the Cochrane Central Register of Controlled Trials [in February 2023], and Embase [from inception to February 2023] and 5 conference proceedings (from January 1990 to April 2023) were searched in this systematic review and meta-analysis.
STUDY SELECTION
Randomized trials directly comparing SBT techniques in critically ill adults or children and reporting at least 1 clinical outcome were selected.
DATA EXTRACTION AND SYNTHESIS
Paired reviewers independently screened citations, abstracted data, and assessed quality for the systematic review and meta-analysis using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA guidelines). Data were pooled using random-effects models.
MAIN OUTCOMES AND MEASURES
Primary outcomes included SBT success, extubation success, and reintubation.
RESULTS
The systematic review and meta-analysis identified 40 trials that included 6716 patients. Low-quality evidence (14 trials [n = 4459]) suggested that patients were not more likely to pass a pressure support (PS) compared with a T-piece SBT (risk ratio [RR], 1.04; 95% CI, 0.97-1.11; P = .31; I2 = 73%), unless 1 outlier trial accounting for all heterogeneity was excluded (RR, 1.09; 95% CI, 1.06-1.12; P < .001; I2 = 0% [13 trials; n = 3939]; moderate-quality evidence), but were significantly more likely to be successfully extubated (RR, 1.07; 95% CI, 1.04-1.10; P < .001; I2 = 0%; 16 trials [n = 4462]; moderate-quality evidence). Limited data (5 trials [n = 502]) revealed that patients who underwent automatic tube compensation/continuous positive airway pressure compared with PS SBTs had a significantly higher successful extubation rate (RR, 1.10; 95% CI, 1.00-1.21; P = .04; I2 = 0% [low-quality evidence]). Compared with T-piece SBTs, high-flow oxygen SBTs (3 trials [n = 386]) had significantly higher successful extubation (RR, 1.06; 95% CI, 1.00-1.11; P = .04; I2 = 0%) and lower reintubation (RR, 0.37; 95% CI, 0.21-0.65; P = <.001; I2 = 0% [both low-quality evidence]) rates. Credible subgroup effects were not found.
CONCLUSIONS AND RELEVANCE
In this systematic review and meta-analysis, the findings suggest that patients undergoing PS compared with T-piece SBTs were more likely to be extubated successfully and more likely to pass an SBT, after exclusion of an outlier trial. Pressure support SBTs were not associated with increased risk of reintubation. Future trials should compare SBT techniques that maximize differences in inspiratory support.

Review
OBJECTIVES
This review aimed to harmoniously summarize and compare outlier rates for various cardiac troponin (cTn) assays, including high-sensitivity-cTn (hs-cTn) assays and contemporary cTn (generation of assays prior to hs-cTn ones) assays, from the published studies.
METHODS
The PRISMA guidelines were utilized to perform this systematic review. Five databases, including PubMed, Scopus, Embase, Cochrane Library, and Web of Science, were searched using specific keywords up to June 30th, 2023. Studies reporting specifically calculated outlier rates for cTn assays when conducting in-vitro diagnosis in human samples were included. Selected studies were then further assessed using the GRADE tool.
RESULTS
Thirteen studies were included. The data from the studies were summarized statistically in this review. The results showed substantial evidence of improved analytical robustness or reduced respective mean rates of outliers, critical outliers, and analytical outliers for hs-cTn assays (0.14 %, 0.18 %, and 0.18 %) compared to contemporary cTn assays (0.63 %, 0.71 %, and 0.50 %).
CONCLUSION
The findings offer promisingly provide a comprehensive reference for laboratory scientists and clinical staff in choosing the most suitable cTn assay for patient care regrading outlier rates. Besides, this review reveals the advancements of hs-cTn assays with lower outlier rates than contemporary cTn assays. The emerging challenges for continuously improving analytical robustness of cTn assays are also elaborated.

Meta-Analysis Review
OBJECTIVE
The aim of this systematic review and meta-analysis (PROSPERO 2020 CRD42020169323) was to evaluate the efficacy of psychological therapy for people with intellectual disabilities.
METHOD
A comprehensive literature search yielded 22,444 studies which were screened for eligibility. Studies were eligible for inclusion if a psychological therapy was delivered to people with intellectual disabilities compared to a group who did not receive the therapy. Thirty-three controlled trials were eligible for inclusion in the review, with 19 included within a DerSimonian-Laird random effects meta-analysis. Subgroup analysis was completed by clinical presentation, and by comparing randomised trials to non-randomised trials, and group-based to individually delivered psychotherapy.
RESULTS
Following the removal of outliers, psychological therapy for a range of mental health problems was associated with a small and significant effect size, g = 0.43, 95% CI [0.20, 0.67], N = 698. There was evidence of heterogeneity and bias due to studies with small sample sizes and a lack of randomisation. Non-randomised studies were associated with a large effect size, g = 0.90, 95% CI [0.47, 1.32], N = 174, while randomised studies were associated with a small effect size, g = 0.36, 95% CI [0.17, 0.55], N = 438, excluding outliers. Individually delivered psychological therapy was associated with a small and non-significant effect size, g = 0.32, 95% CI [-0.01, 0.65], N = 146, while group-based interventions were associated with a small and significant effect size, g = 0.37, 95% CI [0.05, 0.68], N = 361, again, excluding outliers. Psychological therapy for anger was associated with a moderate effect size, g = 0.60, 95% CI [0.26, 0.93], N = 324, while treatment for depression and anxiety was associated with a small and non-significant effect size, g = 0.38, 95% CI [-0.10, 0.85], N = 216, after outliers were removed.
CONCLUSIONS
Studies are fraught with methodological weaknesses limiting the ability to make firm conclusions about the effectiveness of psychological therapy for people with intellectual disabilities. Improved reporting standards, appropriately powered and well-designed trials, and greater consideration of the nature and degree of adaptations to therapy are needed to minimise bias and increase the certainty of conclusions.

Meta-Analysis Review
INTRODUCTION
Aminoglycosides are vital antibiotics for treating Brucella infections, because they interfere with bacterial protein production and are often combined with other antibiotics. They are cost-effective, have fewer side effects, and can penetrate biofilms. The prevalence of brucellosis has increased in recent years, increasing the need for effective treatments. In addition, the emergence of multidrug-resistant Brucella strains has highlighted the need for an updated and comprehensive understanding of aminoglycoside resistance. This systematic review aimed to provide a comprehensive overview of the global prevalence of aminoglycoside resistance in B. melitensis and B. abortus.
METHODS
A systematic search of online databases was conducted and eligible studies met certain criteria and were published in English. Quality assessment was performed using the JBI Checklist. A random-effects model was fitted to the data, and meta-regression, subgroup, and outlier/influential analyses were performed. The analysis was performed using R and the metafor package.
RESULTS
The results of this systematic review and meta-analysis suggested that the average prevalence rates of streptomycin, gentamicin, and amikacin resistance were 0.027 (95% confidence interval [CI], 0.015-0.049), 0.023 (95% CI, 0.017-0.032), and 0.008 (95% CI, 0.002-0.039), respectively. The prevalence of streptomycin resistance was higher in the unidentified Brucella group than in the B. abortus and B. melitensis groups (0.234, 0.046, and 0.017, respectively; p < 0.02). The prevalence of gentamicin resistance increased over time (r = 0.064; 95% CI, 0.018 to 0.111; p = 0.007). The prevalence of resistance did not correlate with the quality score for any antibiotic. Funnel plots showed a potential asymmetry for streptomycin and gentamicin. These results suggest a low prevalence of antibiotic resistance in the studied populations.
CONCLUSION
The prevalence of aminoglycoside resistance in B. melitensis and B. abortus was low. However, gentamicin resistance has increased in recent years. This review provides a comprehensive and updated understanding of aminoglycoside resistance in B. melitensis and B. abortus.

OBJECTIVE
People who have been infected by COVID-19 showing persistent symptoms after 4 weeks from recovery are thought to suffer from Long-COVID syndrome (LC). There is uncertainty on the clinical manifestations of LC. We undertook a systematic review to summarize the available evidence about the main psychiatric manifestations of LC.
METHOD
PubMed (Medline), Scopus, CINHAL, PsycINFO, and EMBASE were searched until May 2022. Studies reporting estimation of emerging psychiatric symptoms and/or psychiatric diagnoses among adult people with LC were included. Pooled prevalence for each psychiatric condition was calculated in absence of control groups to compare with.
RESULTS
Thirty-three reports were included in the final selection, corresponding to 282,711 participants with LC. After 4 weeks from COVID-19 infection recovery, participants reported the following psychiatric symptoms: depression, anxiety, post-traumatic symptoms (PTS), cognitive and sleeping disturbances (i.e., insomnia or hypersomnia). The most common psychiatric manifestation resulted to be sleep disturbances, followed by depression, PTS, anxiety, and cognitive impairment (i.e., attention and memory deficits). However, some estimates were affected by important outlier effect played by one study. If study weight was not considered, the most reported condition was anxiety.
CONCLUSIONS
LC may have non-specific psychiatric manifestations. More research is needed to better define LC and to differentiate it from other post-infectious or post-hospitalization syndromes.

Meta-Analysis Review
BACKGROUND
The accuracy of diaphragm ultrasound for predicting weaning outcome is still debated, despite the publication of numerous studies evaluating this issue.
OBJECTIVE
The aim of this systematic review and meta-analysis was to assess the diagnostic accuracy of diaphragm ultrasound for predicting weaning failure in critically ill patients.
DESIGN AND DATA SOURCES
MEDLINE, Science direct, Cochrane Library, EMBASE and CENTRAL were searched. Two investigators independently selected studies that met the inclusion criteria, and three extracted data and performed a bias analysis using the Quality Assessment of Diagnostic Accuracy Studies-2 instrument. A bivariate model was used to estimate the pooled results for sensitivity, specificity and diagnostic odds ratio. Sources of heterogeneity were explored, and subgroup analyses were performed.
RESULTS
Twenty-eight studies were included in the systematic review, from which 16 studies (816 patients in total) were included in the meta-analysis. The pooled sensitivity, specificity and area under the summary receiver operator characteristic curve were 0.70 (95% CI 0.57-0.80), 0.84 (95% CI 0.73-0.91), and 0.82 (95% Cl 0.78-0.85) for diaphragm thickening fraction, respectively, and 0.71 (95% CI 0.61-0.79), 0.80 (95% CI 0.73-0.86), and 0.82 (95% Cl 0.79-0.86) for diaphragm excursion, respectively. There was substantial heterogeneity among the studies. Meta-regression highlighted significant effects of prevalence of extubation failure, cut-off and risk of bias in flow and timing of the study on diaphragm ultrasound accuracy. By excluding outlier and influential studies, sensitivity was lower and specificity higher for diaphragm thickening fraction.
CONCLUSION
The specificity of diaphragm ultrasound for predicting the risk of extubation failure in critically ill patients was moderate-to-high. However, sensitivity was low because weaning is also affected by non-diaphragm-related factors. Further research in subgroups of critically ill patients applying a homogeneous definition of weaning and uniformly conducted measure is needed to assess the accuracy of diaphragm ultrasound.

Meta-Analysis
PURPOSE
The aim of this review is to evaluate the prevalence of and factors associated with keratoconus in Africa.
METHOD
A systematic online literature search was conducted for articles on keratoconus in Africa. Meta-analysis was performed to estimate the prevalence of keratoconus in Africa. The Freeman-Tukey double arcsine transformation was used to minimize the effects of studies with extremely high or low prevalence estimates on the overall pooled estimates. Leave-one-out sensitivity analysis was used to assess the robustness of the pooled effects and potential outliers. Meta-regression was performed to explore associations between keratoconus, gender and age.
RESULTS
Twelve studies were included in the review; 5 from Egypt, 2 from South Africa, 2 from Kenya, 1 from Sudan, 1 from Ghana and 1 from Nigeria. Two studies were conducted in allergic conjunctivitis patients, 4 in keratoconus patients, 1 in contact lens service seekers, 1 in pre-LASIK patients, 1 in refractive patients and 1 in a student population. Eight studies were included in the meta-analysis. The overall prevalence estimate of keratoconus in Africa was 7.9% (95% CI: 2.5%-16.0%). The prevalence of keratoconus among males and females in Africa was estimated to be 9.3% (95% CI: 2.5%-19.5%) and 5.8% (95% CI: 1.5%-12.7%) respectively. The estimated prevalence of unilateral and bilateral keratoconus was 2.6% (95% CI: 0.4%-6.5%) and 5.8% (95% CI: 1.6%-12.3%), respectively. The estimated prevalence of mild keratoconus was 2.2% (95% CI: 0.7%-4.7%), moderate keratoconus was 3.5% (95% CI: 0.0%-11.8%) and severe keratoconus was 4.0% (95% CI: 0.0%-19.6%). There was no significant association between gender and the prevalence of keratoconus in Africa (p = 0.63), and age and the prevalence of keratoconus in Africa (p = 0.78).
CONCLUSION
The estimated prevalence of keratoconus reported here is higher than prevalence values reported in other meta-analyses or different geographical locations. This is mainly because studies included in this meta-analysis were either conducted on a cohort at high risk of keratoconus or a population with high possibility of finding keratoconus patients. There is a dearth of well-designed population-based studies on keratoconus in Africa, resulting in a lack of epidemiological information. This highlights the urgent need for research on keratoconus in Africa.
