Meta-Analysis
BACKGROUND AND AIMS
Perinatal arterial ischemic stroke (PAIS) often has lifelong neurodevelopmental consequences. We aimed to review early predictors (<4 months of age) of long-term outcome.
METHODS
We carried out a systematic literature search (PubMed and Embase), and included articles describing term-born infants with PAIS that underwent a diagnostic procedure within four months of age, and had any reported outcome parameter ≥12 months of age. Two independent reviewers included studies and performed risk of bias analysis.
RESULTS
We included 41 articles reporting on 1395 infants, whereof 1255 (90%) infants underwent follow-up at a median of 4 years. A meta-analysis was performed for the development of cerebral palsy (n = 23 studies); the best predictor was the qualitative or quantitative assessment of the corticospinal tracts on MRI, followed by standardized motor assessments. For long-term cognitive functioning, bedside techniques including (a)EEG and NIRS might be valuable. Injury to the optic radiation on DTI correctly predicted visual field defects. No predictors could be identified for behavior, language, and post-neonatal epilepsy.
CONCLUSION
Corticospinal tract assessment on MRI and standardized motor assessments are best to predict cerebral palsy after PAIS. Future research should be focused on improving outcome prediction for non-motor outcomes.
IMPACT
We present a systematic review of early predictors for various long-term outcome categories after perinatal arterial ischemic stroke (PAIS), including a meta-analysis for the outcome unilateral spastic cerebral palsy. Corticospinal tract assessment on MRI and standardized motor assessments are best to predict cerebral palsy after PAIS, while bedside techniques such as (a)EEG and NIRS might improve cognitive outcome prediction. Future research should be focused on improving outcome prediction for non-motor outcomes.

Meta-Analysis
PURPOSE
To evaluate the safety and efficacy of sacroplasty for the treatment of osteoporotic and malignant sacral fractures by performing a systematic review and meta-analysis of existing literature.
MATERIALS AND METHODS
PubMed, Web of Science, and SCOPUS databases were searched from their inception until February 2018 for articles describing sacroplasty. Inclusion criteria were as follows: studies reporting > 5 patients, and pain assessment before and after the procedure recorded with visual analog scale (VAS). Demographic data, procedural details, technical success rates, VAS scores before and after the procedure, and procedural complications were recorded. A random-effects meta-analyses of the VAS pain score before the procedure, at 24-48 hours, at 6 months, and at 12 months were calculated.
RESULTS
Nineteen studies (18 case series and 1 cohort study) were identified consisting of 861 total patients (682 women and 167 men; mean age 73.89 ± 9.73 years). Patients underwent sacroplasty for the following indications: sacral insufficiency fractures secondary to osteoporosis (n = 664), malignancy (n = 167), and nonspecified sacral insufficiency fractures (n = 30). Technical and clinical successes were achieved in 98.9% (852/861) and 95.7% (623/651) of patients undergoing sacroplasty, respectively. The pooled major complication rate was 0.3%, with 3 patients requiring surgical decompression for cement leakage. Random-effects meta-analyses demonstrated statistically significant differences in the VAS pain level at preprocedure, 24-48 hours, 6 months, and 12 months, with cumulative pain scores of 8.32 ± 0.01, 3.55 ± 0.01, 1.48 ± 0.01, and 0.923 ± 0.01, respectively.
CONCLUSIONS
Sacroplasty appears safe and effective for pain relief in patients with osteoporotic or malignant sacral fractures, with statistically significant sustained improvement in VAS pain scores up to 12 months.

Review
Myofascial pain syndrome (MPS) is characterized by the presence of clinically detected myofascial trigger points (MTrPs). Diagnostic ultrasound (US) has been proposed as a method to strengthen the reliability of MTrP localization, thus potentially improving the efficacy and safety profile of interventional procedures. The objective is to evaluate the benefit and safety profile of any US-guided interventional procedure for MPS. Medline, Embase, PubMed, the Allied and Complementary Medicine Database (AMED), and Web of Science were systematically searched from their inception to May 2020 for any randomized controlled trial that evaluated treatment benefit and safety of any US-guided interventional procedure for MPS. The primary outcome of interest was pain severity. Additional outcomes of interest were function and adverse effects. The risk of bias was assessed using the Risk of Bias V.2.0 tool. eleven studies met all inclusion and exclusion criteria. Two studies (n=174) with a high risk of bias revealed some evidence supporting US guidance over blinded interventions for improvement in pain and function. Eight studies (n=483) with varying risks of bias were of head-to-head comparisons of different US modalities. These studies revealed that US-guided local anesthetic injections were inferior to US-guided pulse radiofrequency and US-guided dry needling (DN). US-guided DN was also found to be superior to US-guided platelet-rich-plasma injections but inferior to US-guided miniscalpel. Meanwhile, one study (n=21) with some concerns of bias found that US-guided local anesthetic injections were superior to non-steroidal anti-inflammatory drugs for pain outcomes and fewer adverse events. All US-guided procedures resulted in zero or minimal self-limited adverse events. Issues with clinical relevance, limited sample sizes, and small point estimates warrant more high-quality research to better characterize the possible value of US-guided injections.

Meta-Analysis Review
We performed this study to provide the latest evidence of the diagnostic accuracy of all Aspergillus antibodies for chronic pulmonary aspergillosis (CPA). In this meta-analysis, we searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, and other databases, until 19 March 2020, for studies that examined the diagnostic accuracy of each Aspergillus-specific antibody for CPA and assessed the risk of bias using the revised Quality Assessment of Diagnostic Accuracy Studies-2 tool. We integrated the results using a hierarchical summary receiver operating characteristic (HSROC) model and calculated the point estimates of specificity with sensitivity fixed at 0.90 using the HSROC curve. We identified 32 published and one unpublished studies, including 75 studies on five antibody test types: 18 of precipitin test (2810 participants), 46 of IgG (8197), three of IgA (283), six of IgM (733) and two of combined IgG and IgM (IgG + IgM) (920). The results of specificity with sensitivity fixed at 0.90 were as follows: precipitin test, 0.93 (95% credible intervals: 0.86, 1.00); IgG, 0.90 (0.86, 0.95); IgA, 0.74 (0.00, 1.00); IgM, 0.50 (0.37, 0.53); IgG + IgM, 0.47 (0.00, 1.00). However, the precipitin test showed imprecision and instability in the sensitivity analysis. Most studies had a high risk of bias due to the case-control design. Although there is lack of applicability for malignancy or immunosuppressive patients, our study suggests a preference for IgG over other antibody tests in CPA screening. Particularly, IgG should be used as an adjunct when ruling out CPA.

Meta-Analysis Review
BACKGROUND AND AIMS
Diagnosis of esophageal cancer or precursor lesions by endoscopic imaging depends on endoscopist expertise and is inevitably subject to interobserver variability. Studies on computer-aided diagnosis (CAD) using deep learning or machine learning are on the increase. However, studies with small sample sizes are limited by inadequate statistical strength. Here, we used a meta-analysis to evaluate the diagnostic test accuracy (DTA) of CAD algorithms of esophageal cancers or neoplasms using endoscopic images.
METHODS
Core databases were searched for studies based on endoscopic imaging using CAD algorithms for the diagnosis of esophageal cancer or neoplasms and presenting data on diagnostic performance, and a systematic review and DTA meta-analysis were performed.
RESULTS
Overall, 21 and 19 studies were included in the systematic review and DTA meta-analysis, respectively. The pooled area under the curve, sensitivity, specificity, and diagnostic odds ratio of CAD algorithms for the diagnosis of esophageal cancer or neoplasms in the image-based analysis were 0.97 (95% confidence interval [CI], 0.95-0.99), 0.94 (95% CI, 0.89-0.96), 0.88 (95% CI, 0.76-0.94), and 108 (95% CI, 43-273), respectively. Meta-regression showed no heterogeneity, and no publication bias was detected. The pooled area under the curve, sensitivity, specificity, and diagnostic odds ratio of CAD algorithms for the diagnosis of esophageal cancer invasion depth were 0.96 (95% CI, 0.86-0.99), 0.90 (95% CI, 0.88-0.92), 0.88 (95% CI, 0.83-0.91), and 138 (95% CI, 12-1569), respectively.
CONCLUSIONS
CAD algorithms showed high accuracy for the automatic endoscopic diagnosis of esophageal cancer and neoplasms. The limitation of a lack in performance in external validation and clinical applications should be overcome.

Meta-Analysis Review
BACKGROUND
Most colorectal polyps are diminutive and benign, especially those in the rectosigmoid colon, and the resection of these polyps is not cost-effective. Advancements in image-enhanced endoscopy have improved the optical prediction of colorectal polyp histology. However, subjective interpretability and inter- and intraobserver variability prohibits widespread implementation. The number of studies on computer-aided diagnosis (CAD) is increasing; however, their small sample sizes limit statistical significance.
OBJECTIVE
This review aims to evaluate the diagnostic test accuracy of CAD models in predicting the histology of diminutive colorectal polyps by using endoscopic images.
METHODS
Core databases were searched for studies that were based on endoscopic imaging, used CAD models for the histologic diagnosis of diminutive colorectal polyps, and presented data on diagnostic performance. A systematic review and diagnostic test accuracy meta-analysis were performed.
RESULTS
Overall, 13 studies were included. The pooled area under the curve, sensitivity, specificity, and diagnostic odds ratio of CAD models for the diagnosis of diminutive colorectal polyps (adenomatous or neoplastic vs nonadenomatous or nonneoplastic) were 0.96 (95% CI 0.93-0.97), 0.93 (95% CI 0.91-0.95), 0.87 (95% CI 0.76-0.93), and 87 (95% CI 38-201), respectively. The meta-regression analysis showed no heterogeneity, and no publication bias was detected. Subgroup analyses showed robust results. The negative predictive value of CAD models for the diagnosis of adenomatous polyps in the rectosigmoid colon was 0.96 (95% CI 0.95-0.97), and this value exceeded the threshold of the diagnosis and leave strategy.
CONCLUSIONS
CAD models show potential for the optical histological diagnosis of diminutive colorectal polyps via the use of endoscopic images.

BACKGROUND
Periorbital and orbital cellulitis are inflammatory conditions of the eye that can be difficult to distinguish using clinical examination alone. Computer tomography (CT) scans are often used to differentiate these two infections and to evaluate for complications. Orbital ultrasound (US) could be used as a diagnostic tool to supplement or replace CT scans as the main diagnostic modality. No prior systematic review has evaluated the diagnostic test accuracy (DTA) of ultrasound compared to cross-sectional imaging.
OBJECTIVE
To conduct a systematic review of studies evaluating the DTA of orbital ultrasound compared with cross-sectional imaging, to diagnose orbital cellulitis.
METHODS
MEDLINE, EMBASE, CENTRAL, and Web of Science were searched from inception to August 10, 2022. All study types were included that enrolled patients of any age with suspected or diagnosed orbital cellulitis who underwent ultrasound and a diagnostic reference standard (i.e., CT or magnetic resonance imaging [MRI]). Two authors screened titles/abstracts for inclusion, extracted data, and assessed the risk of bias.
RESULTS
Of the 3548 studies identified, 20 were included: 3 cohort studies and 17 case reports/series. None of the cohort studies directly compared the diagnostic accuracy of ultrasound with CT or MRI, and all had high risk of bias. Among the 46 participants, diagnostic findings were interpretable in 18 (39%) cases which reported 100% accuracy. We were unable to calculate sensitivity and specificity due to limited data. In the descriptive analysis of the case reports, ultrasound was able to diagnose orbital cellulitis in most (n = 21/23) cases.
CONCLUSION
Few studies have evaluated the diagnostic accuracy of orbital ultrasound for orbital cellulitis. The limited evidence based on low quality studies suggests that ultrasound may provide helpful diagnostic information to differentiate orbital inflammation. Future research should focus studies to determine the accuracy of orbital US and potentially reduce unnecessary exposure to radiation.

Review
CONTEXT
Female bladder outlet obstruction (fBOO) is a relatively uncommon condition compared with its male counterpart. Several criteria have been proposed to define fBOO, but the comparative diagnostic accuracy of these remains uncertain.
OBJECTIVE
To identify and compare different tests to diagnose fBOO through a systematic review process.
EVIDENCE ACQUISITION
A systematic review of the literature was performed according to the Cochrane Handbook and Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. The EMBASE/MEDLINE/Cochrane databases were searched up to August 4, 2020. Studies on women ≥18 yr of age with suspected bladder outlet obstruction (BOO) involving diagnostic tests were included. Pressure-flow studies or fluoroscopy was used as the reference standard where possible. Two reviewers independently screened all articles, searched reference lists of retrieved articles, and performed data extraction. The risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2).
EVIDENCE SYNTHESIS
Overall, 28 nonrandomised studies involving 10 248 patients were included in the qualitative analysis. There was significant heterogeneity regarding the characteristics of women included in BOO cohorts (ie, mixed cohorts including both anatomical and functional BOO). Pressure-flow studies ± fluoroscopy was evaluated in 25 studies. Transperineal Doppler ultrasound was used to evaluate bladder neck dynamics in two studies. One study tested the efficacy of transvaginal ultrasound. The urodynamic definition of fBOO also varied amongst studies with different parameters and thresholds used, which precluded a meta-analysis. Three studies derived nomograms using the maximum flow rate (Q) and voiding detrusor pressure at Q. The sensitivity, specificity, and overall accuracy ranges were 54.6-92.5%, 64.6-93.9%, and 64.1-92.2%, respectively.
CONCLUSIONS
The available evidence on diagnostic tests for fBOO is limited and heterogeneous. Pressure-flow studies ± fluoroscopy remains the current standard for diagnosing fBOO.
PATIENT SUMMARY
Evidence on tests used to diagnose female bladder outlet obstruction was reviewed. The most common test used was pressure-flow studies ± fluoroscopy, which remains the current standard for diagnosing bladder outlet obstruction in women. TAKE HOME MESSAGE: The available evidence on diagnostic tests for female bladder outlet obstruction is limited and heterogeneous. The most common test used was video-urodynamics, which remains the current standard for diagnosing bladder outlet obstruction in women.

Meta-Analysis Review
BACKGROUND
Lung cancer is the principal cause of cancer-related deaths worldwide. Early detection of lung cancer with screening is indispensable to reduce the high morbidity and mortality rates. Artificial intelligence (AI) is widely utilised in healthcare, including in the assessment of medical images. A growing number of reviews studied the application of AI in lung cancer screening, but no overarching meta-analysis has examined the diagnostic test accuracy (DTA) of AI-based imaging for lung cancer screening.
OBJECTIVE
To systematically review the DTA of AI-based imaging for lung cancer screening.
METHODS
PubMed, EMBASE, Cochrane Library, CINAHL, IEEE Xplore, Web of Science, ACM Digital Library, Scopus, PsycINFO, and ProQuest Dissertations and Theses were searched from inception to date. Studies that were published in English and that evaluated the performance of AI-based imaging for lung cancer screening were included. Two independent reviewers screened titles and abstracts and used the Quality Assessment of Diagnostic Accuracy Studies-2 tool to appraise the quality of selected studies. Grading of Recommendations Assessment, Development, and Evaluation to diagnostic tests was used to assess the certainty of evidence.
RESULTS
Twenty-six studies with 150,721 imaging data were included. Hierarchical summary receiver-operating characteristic model used for meta-analysis demonstrated that the pooled sensitivity for AI-based imaging for lung cancer screening was 94.6 % (95 % CI: 91.4 % to 96.7 %) and specificity was 93.6 % (95 % CI: 88.5 % to 96.6 %). Subgroup analyses revealed that similar results were found among different types of AI, region, data source, and year of publication, but the overall quality of evidence was very low.
CONCLUSION
AI-based imaging could effectively detect lung cancer and be incorporated into lung cancer screening programs. Further high-quality DTA studies on large lung cancer screening populations are required to validate AI's role in early lung cancer detection.

Review
OBJECTIVE
Carpal tunnel syndrome (CTS) is the most common peripheral entrapment mononeuropathy. The purpose of this systematic review is to evaluate the reported clinical effectiveness and safety of ultrasound-guided percutaneous carpal tunnel release (USCTR) for the treatment of CTS.
LITERATURE SURVEY
PubMed, EMBASE, and ScienceDirect databases were queried from database inception to February 20, 2021, to identify clinical studies on USCTR.
METHODOLOGY
Two reviewers independently completed title, abstract, and full-text screening, and they extracted data in duplicate for analysis. Procedure techniques, outcome measures, and complications were descriptively analyzed.
SYNTHESIS
Eighty-seven studies were eligible for screening. Twenty studies (three randomized controlled trials, three prospective cohort studies, and 14 case series) met inclusion criteria, with a total of 1772 USCTR cases. The overall level of evidence was very low, with seven studies with at least moderate risk of bias. Thirteen studies exceeded the minimal clinically important difference (MCID) for the Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SS) and Boston Carpal Tunnel Questionnaire Functional Status Scale (BCTQ-FS), and six studies exceeded the MCID for the Quick Disabilities of Arm, Shoulder & Hand (QDASH). Five studies reported statistically significant improvement in these functional outcome measures as early as the first week post-procedure. A major complication occurred in one patient who developed suspected compartment syndrome, and minor complications were reported in 24 patients.
CONCLUSIONS
Based on very low level of evidence, early studies suggest that USCTR may be an effective treatment for CTS, with potential for short post-procedure recovery times.
