Review
OBJECTIVE
Rapid growth of antipsychotic use among children and adolescents at the turn of the 21st century led Medicaid programs to implement 3 types of system-wide interventions: antipsychotic monitoring programs, clinician prescribing supports, and delivery system enhancements. This systematic review assessed the available evidence base for and relative merits of these system-wide interventions that aim to improve antipsychotic treatment and management.
METHOD
Using PRISMA guidelines, eligible studies were written in English and evaluated system-wide interventions to monitor antipsychotic treatment or promote antipsychotic management among children and adolescents (0-21 years of age). Studies were identified through Ovid MEDLINE and PsychInfo (years 1990-2018) and an environmental scan. From an initial review of 824 publications, 17 studies met eligibility criteria. Two authors independently conducted quality assessments using the Crowe Critical Appraisal Tool. Findings were summarized descriptively.
RESULTS
Identified studies (n = 17) evaluated prior authorization programs (n = 10), drug utilization reviews (n = 2), quality improvement (n = 4), care coordination programs (n = 1), and multimodal initiatives (n = 2). Studies were predominantly pre-post analyses, without a comparison group. With the exception of care coordination and drug utilization reviews, more than half of the interventions in each category were associated with significant reduction in antipsychotic treatment or promotion of best practice parameters.
CONCLUSION
This evidence review concludes that evaluations of prior authorization programs demonstrate reductions in antipsychotic treatment, though evidence of impact of other system-wide interventions and other outcomes is limited. Additional research is necessary to investigate whether interventions influenced antipsychotic prescribing independent of secular trends, the comparative effectiveness and cost-effectiveness of interventions, the effect on functional outcomes, and the potential for unintended consequences.

Meta-Analysis Review
BACKGROUND
A number of publications have demonstrated that deep learning (DL) algorithms matched or outperformed clinicians in image-based cancer diagnostics, but these algorithms are frequently considered as opponents rather than partners. Despite the clinicians-in-the-loop DL approach having great potential, no study has systematically quantified the diagnostic accuracy of clinicians with and without the assistance of DL in image-based cancer identification.
OBJECTIVE
We systematically quantified the diagnostic accuracy of clinicians with and without the assistance of DL in image-based cancer identification.
METHODS
PubMed, Embase, IEEEXplore, and the Cochrane Library were searched for studies published between January 1, 2012, and December 7, 2021. Any type of study design was permitted that focused on comparing unassisted clinicians and DL-assisted clinicians in cancer identification using medical imaging. Studies using medical waveform-data graphics material and those investigating image segmentation rather than classification were excluded. Studies providing binary diagnostic accuracy data and contingency tables were included for further meta-analysis. Two subgroups were defined and analyzed, including cancer type and imaging modality.
RESULTS
In total, 9796 studies were identified, of which 48 were deemed eligible for systematic review. Twenty-five of these studies made comparisons between unassisted clinicians and DL-assisted clinicians and provided sufficient data for statistical synthesis. We found a pooled sensitivity of 83% (95% CI 80%-86%) for unassisted clinicians and 88% (95% CI 86%-90%) for DL-assisted clinicians. Pooled specificity was 86% (95% CI 83%-88%) for unassisted clinicians and 88% (95% CI 85%-90%) for DL-assisted clinicians. The pooled sensitivity and specificity values for DL-assisted clinicians were higher than for unassisted clinicians, at ratios of 1.07 (95% CI 1.05-1.09) and 1.03 (95% CI 1.02-1.05), respectively. Similar diagnostic performance by DL-assisted clinicians was also observed across the predefined subgroups.
CONCLUSIONS
The diagnostic performance of DL-assisted clinicians appears better than unassisted clinicians in image-based cancer identification. However, caution should be exercised, because the evidence provided in the reviewed studies does not cover all the minutiae involved in real-world clinical practice. Combining qualitative insights from clinical practice with data-science approaches may improve DL-assisted practice, although further research is required.

Review
Epigenetic mechanisms are potential mediators of the physiological response to abuse by altering the genetic predisposition of the cellular response to the environment, leading to changes in the regulation of multiple organ systems. This study was established to review the epigenetic mechanisms associated with childhood abuse as well as the long-term determinants that these epigenetic changes may have on future illness. We retrospectively analysed the effect of exposure to adverse childhood experiences (ACEs, specifically those relating to childhood maltreatment) between the ages of 0 and 16 years on the human epigenome, as well as possible clinical associations. After meeting inclusion and exclusion criteria, 36 articles were included in this systematic review. Eight of these studies did not find a relationship between childhood maltreatment and DNA methylation. Of the remaining 28 studies, nine were genome-wide association studies, whereas the rest were candidate gene studies, mainly studying effects on neuroendocrine, serotoninergic and immunoregulatory systems. Meta-analysis of correlation coefficients from candidate gene studies estimated an association of childhood adversity and DNA methylation variation at = 0.291 ( < 0.0001), and meta-analysis of two epigenome-wide association studies (EWASs) identified 44 differentially methylated CpG sites. In conclusion, childhood maltreatment may mediate epigenetic mechanisms through DNA methylation, thereby affecting physiological responses and conferring a predisposition to an increased risk for psychopathology and forensic repercussions. Similar evidence for somatic illnesses is not yet available. KEY POINTSAdverse childhood experiences are associated with increased mortality partly explained by acquired epigenetic changesThere is a positive correlation between childhood abuse and DNA methylation at specific gene sitesThe cumulative effect of different types of childhood abuse and neglect may lead to changes in DNA methylationEpigenome changes associated with childhood abuse appear to be involved in the development of psychiatric illness in adulthoodStudying epigenetic changes may have important public health and forensic applications in the future.

Review
The global response to infectious diseases has seen a renewed interest in the use of community engagement to support research and relief efforts. From a perspective rooted in the social sciences, the concept of vulnerability offers an especially useful analytical frame for pursuing community engagement in a variety of contexts. However, few have closely examined the concept of vulnerability in community engagement efforts, leading to a need to better understand the various theories that underline the connections between the two. This literature review searched four databases (covering a total of 537 papers), resulting in 15 studies that analyze community engagement using a framing of vulnerability, broadly defined, in the context of an infectious disease, prioritizing historical and structural context and the many ways of constituting communities. The review identified historical and structural factors such as trust in the health system, history of political marginalization, various forms of racism and discrimination, and other aspects of vulnerability that are part and parcel of the main challenges faced by communities. The review found that studies using vulnerability within community engagement share some important characteristics (e.g., focus on local history and structural factors) and identified a few theoretical avenues from the social sciences which integrate a vulnerability-informed approach in community engagement. Finally, the review proposes an approach that brings together the concepts of vulnerability and community engagement, prioritizing participation, empowerment, and intersectoral collaboration.

Meta-Analysis Review
Complications associated with subaxial placement of pedicle screws versus lateral mass screws in the cervical spine: systematic review and meta-analysis comprising 1768 patients and 8636 screws.
Lateral mass screw (LMS) fixation for the treatment of subaxial cervical spine instability or deformity has been traditionally associated with few neurovascular complications. However, cervical pedicle screw (CPS) fixation has recently increased in popularity, especially with navigation assistance, because of the higher pullout strength of the pedicle screws. To their knowledge, the authors conducted the first meta-analysis comparing the complication rates during and/or after CPS and LMS placement for different pathologies causing cervical spine instability. A systematic literature search of PubMed and Embase from inception to January 12, 2021 was performed to identify studies reporting CPS and/or LMS-related complications. Complications were categorized into intraoperative and early postoperative (within 30 days of surgery) and late postoperative (after 30 days from surgery) complications. All studies that met the prespecified inclusion criteria were pooled and cumulatively analyzed. A total of 24 studies were conducted during the time frame of the search and comprising 1768 participants and 8636 subaxially placed screws met the inclusion criteria. The CPS group experienced significantly more postoperative C5 palsy (odds ratio [OR] = 3.48, 95% confidence interval [CI] = 1.27-9.53, p < 0.05). Otherwise, there were no significant differences between the LMS and CPS groups. There were no significant differences between the CPS and LMS groups in terms of neurovascular procedure-related complications other than significantly more C5 palsy in the CPS group.

Obesity remains a serious public health concern in rich countries and the current obesogenic food environments and food insecurity are predictors of this disease. The impact of these variables on rising obesity trends is, however, mixed and inconsistent, due to measurement issues and cross-sectional study designs. To further the work in this area, this review aimed to summarize quantitative and qualitative data on the relationship between these variables, among adults and children across high-income countries. A mixed-method systematic review was conducted using 13 electronic databases, up to August 2021. Two authors independently extracted data and evaluated quality of publications. Random-effects meta-analysis was used to estimate the odds ratio (OR) for the association between food insecurity and obesity. Where statistical pooling for extracted statistics related to food environments was not possible due to heterogeneity, a narrative synthesis was performed. Meta-analysis of 36,113 adults and children showed statistically significant associations between food insecurity and obesity (OR: 1.503, 95% confidence interval: 1.432-1.577, < .05). Narrative synthesis showed association between different types of food environments and obesity. Findings from qualitative studies regarding a reliance on energy-dense, nutrient-poor foods owing to their affordability and accessibility aligned with findings from quantitative studies. Results from both qualitative and quantitative studies regarding the potential links between increased body weight and participation in food assistance programs such as food banks were supportive of weight gain. To address obesity among individuals experiencing food insecurity, wide-reaching approaches are required, especially among those surrounded by unhealthy food environments which could potentially influence food choice.

Review
Access to healthcare for adolescents is often overlooked in the United States due to federal and state-sponsored insurance programs such as Medicaid and the Children's Health Insurance Program. While these types of programs provide some relief, the issue of healthcare access goes beyond insurance coverage and includes an array of ecological factors that hinder youths from receiving services. The purpose of this scoping review was to identify social-ecological barriers to adolescents' healthcare access and utilization in the United States. We followed the PRISMA and scoping review methodological framework to conduct a comprehensive literature search in eight electronic databases for peer-reviewed articles published between 2010 and 2020. An inductive content analysis was performed to thematize the categories identified in the data extraction based on the Social-Ecological Model (SEM). Fifty studies were identified. Barriers across the five SEM levels emerged as primary themes within the literature, including intrapersonal-limited knowledge of and poor previous experiences with healthcare services, interpersonal-cultural and linguistic barriers, organizational-structural barriers in healthcare systems, community-social stigma, and policy-inadequate insurance coverage. Healthcare access for adolescents is a systems-level problem requiring a multifaceted approach that considers complex and adaptive behaviors.

BACKGROUND
In recent years, more than 120 million people each year have needed urgent humanitarian assistance and protection. Armed conflict has profoundly negative consequences in communities. Destruction of civilian infrastructure impacts access to basic health services and complicates widespread emergency responses. The number of conflicts occurring is increasing, lasting longer and affecting more people today than a decade ago. The number of children living in conflict zones has been steadily increasing since the year 2000, increasing the need for health services and resources. This review systematically synthesised the indexed and grey literature reporting on the delivery of trauma and rehabilitation interventions for conflict-affected populations.
METHODS
A systematic search of literature published from 1 January 1990 to 31 March 2018 was conducted across several databases. Eligible publications reported on women and children in low and middle-income countries. Included publications provided information on the delivery of interventions for trauma, sustained injuries or rehabilitation in conflict-affected populations.
RESULTS
A total of 81 publications met the inclusion criteria, and were included in our review. Nearly all of the included publications were observational in nature, employing retrospective chart reviews of surgical procedures delivered in a hospital setting to conflict-affected individuals. The majority of publications reported injuries due to explosive devices and remnants of war. Injuries requiring orthopaedic/reconstructive surgeries were the most commonly reported interventions. Barriers to health services centred on the distance and availability from the site of injury to health facilities.
CONCLUSIONS
Traumatic injuries require an array of medical and surgical interventions, and their effective treatment largely depends on prompt and timely management and referral, with appropriate rehabilitation services and post-treatment follow-up. Further work to evaluate intervention delivery in this domain is needed, particularly among children given their specialised needs, and in different population displacement contexts.

Meta-Analysis
OBJECTIVE
To support evidence informed decision-making, we systematically examine the effectiveness and cost-effectiveness of community engagement interventions on routine childhood immunisation outcomes in low-income and middle-income countries (LMICs) and identify contextual, design and implementation features associated with effectiveness.
DESIGN
Mixed-methods systematic review and meta-analysis.
DATA SOURCES
21 databases of academic and grey literature and 12 additional websites were searched in May 2019 and May 2020.
ELIGIBILITY CRITERIA FOR SELECTING STUDIES
We included experimental and quasi-experimental impact evaluations of community engagement interventions considering outcomes related to routine child immunisation in LMICs. No language, publication type, or date restrictions were imposed.
DATA EXTRACTION AND SYNTHESIS
Two independent researchers extracted summary data from published reports and appraised quantitative risk of bias using adapted Cochrane tools. Random effects meta-analysis was used to examine effects on the primary outcome, full immunisation coverage.
RESULTS
Our search identified over 43 000 studies and 61 were eligible for analysis. The average pooled effect of community engagement interventions on full immunisation coverage was standardised mean difference 0.14 (95% CI 0.06 to 0.23, I=94.46). The most common source of risk to the quality of evidence (risk of bias) was outcome reporting bias: most studies used caregiver-reported measures of vaccinations received by a child in the absence or incompleteness of immunisation cards. Reasons consistently cited for intervention success include appropriate intervention design, including building in community engagement features; addressing common contextual barriers of immunisation and leveraging facilitators; and accounting for existing implementation constraints. The median intervention cost per treated child per vaccine dose (excluding the cost of vaccines) to increase absolute immunisation coverage by one percent was US$3.68.
CONCLUSION
Community engagement interventions are successful in improving outcomes related to routine child immunisation. The findings are robust to exclusion of studies assessed as high risk of bias.

Meta-Analysis Review
On 23 July 2022, the World Health Organization declared the global mpox outbreak as a public health emergency of international significance. The mpox virus (MPXV) that caused the outbreak was classified as clade IIb, which belongs to the West African clade. However, the relationship between MPXV clades and symptoms, as well as the severity of mpox outcomes, is not fully understood. Thus, we aimed to investigate the global mpox prevalence and the differences in clinical manifestations and outcomes among patients with mpox between pre-outbreak (2003-2021) and the current mpox outbreak. In this systematic review and meta-analysis, PubMed/MEDLINE, Web of Science, Embase, Cumulative Index to Nursing and Allied Health Literature, and Google Scholar were searched using the keyword "monkeypox" and "mpox" up to 13 October 2022. A random effects model was used to obtain the pooled prevalence and 95% confidence intervals. This study included 27 articles, and 5698 patients with mpox with 19 distinctive features from 19 countries across five continents were assessed. Patients with mpox during the 2022 mpox outbreak showed mild clinical manifestations and outcomes compared with those before the 2022 mpox outbreak: mild rash (relative ratio [RR]: 5.09, 95% confidence interval [CI]: 1.52-17.08), fever (0.68, 0.49-0.94), pruritus (0.25, 0.19-0.32), myalgia (0.50, 0.31-0.81), headache (0.56, 0.35-0.88), skin ulcer (0.32, 0.17-0.59), abdominal symptom (0.29, 0.20-0.42), pharyngitis (0.32, 0.18-0.58), nausea or vomiting (0.15, 0.02-0.93), conjunctivitis (0.11, 0.03-0.38), concomitant infection with HIV (1.70, 0.95-3 0.04), and death (0.02, 0.001-0.31). MPXV clade IIb exhibited higher infectivity but may cause mild disease symptoms and low mortality rate. It is important to consider MPXV infection in patients with mpox-related features and/or a history of sexual transmission to prevent the spread of the disease and recognise the current pandemic threat.
