PROTOCOL: The efficacy of nutritional interventions in reducing childhood/youth aggressive and antisocial behavior: A systematic review and meta-analysis

This is a protocol for a Campbell systematic review of intervention effectiveness. The goal of this systematic review is to answer the following questions based on the available empirical evidence: Are there nutritional interventions (dietary manipulation, fortification or supplementation) that can reduce excessive aggression towards others in children/youth? If yes, how strong is their effect and is there a difference among the three intervention types? Are there nutritional interventions that can reduce antisocial behaviors in children/youth? If yes, how strong is their effect and is there a difference among the intervention types? Are there nutritional interventions that can reduce violent offending in children/youth? If yes, how strong is their effect and is there a difference among the intervention types? Are there nutritional interventions that can reduce non-violent offending in children/youth? If yes, how strong is their effect and is there a difference among the intervention types? What implementation barriers and solutions to these exist in relation to the above nutritional interventions in children/youth?

Canadian cannabis education resources to support youth health literacy: A scoping review and environmental scan

Background

The 2018 legalisation of cannabis in Canada sparked concern and conversation about the potential negative impacts of youth cannabis use. It is clear that young people are already engaging in cannabis use for a variety of reasons; therefore, youth cannabis education is desirable to promote harm reduction and reduce the risk of adverse physical and mental health outcomes.

Objective

To identify and categorise Canadian cannabis education resources using a social-ecological approach informed by the youth health literacy framework, considering multiple factors at the micro-, meso- and macro-levels that influence health literacy and impact behaviour.

Methods

In line with scoping review methodology, database searches and an environmental scan of materials were completed. Specific inclusion criteria were identified to encompass all Canadian cannabis education resources directed towards young people aged 9-18 years and adults in contact with youth.

Results

A total of 60 resources were identified and categorised using the youth health literacy framework in terms of their focus on (1) micro influences (resources for youth); (2) meso influences (resources for teachers, parents, mentors); and (3) macro influences (resources for indigenous communities and medical professionals).

Conclusions

While many resources were identified, issues exist with the accessibility, quality and multicultural considerations of such resources, warranting the development of comprehensive, evidence-based and harm reduction-focused cannabis education for youth.

A Systematic Review of Economic Evaluations Conducted for Interventions to Screen, Treat, and Manage Retinopathy of Prematurity (ROP) in the United States, United Kingdom, and Canada

PURPOSE

A systematic literature review (SLR) of economic evaluations (EE) conducted for interventions to screen, treat, and manage retinopathy of prematurity (ROP) in the United States (US), United Kingdom (UK), and Canada was performed.

METHODS

The SLR accessed the MEDLINE, Embase, Cochrane, Web of Science, Health Business Elite, Econ. Lit, NHS EED, and Google Scholar databases over the period 1st January 2000 to 4th August 2021. The key Medical Subject Heading (MeSH) search terms used included: Retinopathy of prematurity, Cost-effectiveness analysis, Cost-utility analysis, Cost of illness, Cost-benefit analysis, Cost minimization analysis, Incremental cost-effectiveness ratio, Quality adjusted life years, return on investment, burden of illness, disability adjusted life years, and Economic evaluation. Screening was conducted using Covidence, and the risk of bias was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. Data extraction was performed using MS Excel.

RESULTS

1,527 articles were examined with nine (9) papers identified, one (1) from the UK; two (2) from Canada and six (6) from the US. Cost-effectiveness analysis was the main form of EE conducted (n = 5) and telemedicine screening (n = 3) was found to be highly cost-effective for ROP with the ICER values ranging from £446 to £4,240 per Quality Adjusted Life Year (QALY) in 2021 figures. 73% of included studies complied with the CHEERS checklist for EE.

CONCLUSIONS

ROP screening and treatment strategies reviewed were highly cost-effective. This review may assist eye health policymakers in planning nationwide screening and treatment programs to combat vision loss and blindness due to ROP.
