Vaping among children and young people (CYP) has increased globally over the past decade, with rates stabilising in the UK in recent years. Factors such as curiosity, social influence, stress management and attractive flavours contribute to its popularity. Although the long-term health impacts are uncertain, vaping poses risks including nicotine dependence, cardiovascular and respiratory issues, and cognitive impairment, though evidence on long-term effects is still emerging. Despite established smoking cessation programmes for adults, tailored resources for vaping cessation among CYP remain scarce, particularly within healthcare settings, which offer unique opportunities for professional intervention and ongoing support. The objective of this review is to assess the extent and nature of available literature on interventions delivered in healthcare settings to support vaping cessation among CYP under the age of 18 years.

This scoping review will include studies targeting CYP under the age of 18 years, specifically focusing on interventions delivered within healthcare settings. Studies outside healthcare contexts or those without healthcare provider involvement will be excluded. Additionally, interventions delivered solely to parents or carers will not be considered.

A comprehensive search will be conducted in MEDLINE, Embase, Web of Science, Cochrane Library and CINAHL from January 2004 to present, with additional grey literature from sources including grey literature repositories and Google Scholar. Results will be imported into Rayyan for screening, with two independent reviewers assessing studies for inclusion. Data extraction will include study design, population characteristics (including explicit age ranges, specifically CYP under 18 years), intervention details and outcomes. A descriptive synthesis will map study characteristics, while thematic analysis will identify intervention themes and healthcare contexts.

Ethics approval is not required for this secondary analysis. Findings will be disseminated through publication, conference presentations and shared with public health stakeholders.

To map, summarise and analyse the methodologies of corneal nerve fibre imaging in studies using in vivo confocal microscopy (IVCM) in diabetes and assess the potential for standardising methods and reporting.

A scoping review was conducted using five databases, MEDLINE, Embase, Cochrane, Web of Science and Scopus, with search terms related to IVCM, diabetes and corneal nerves. Two researchers independently screened the studies for eligibility. Relevant data were extracted and systematically analysed.

Out of 1533 screened articles, 195 met the inclusion criteria. Spanning from 2000 to 2024, the studies showed high variability in image acquisition, image processing, image analysis and reporting detail. Most studies used laser scanning confocal microscopy, examining the central cornea in both eyes in patients with type 2 diabetes, manually selecting 3–6 images from each eye, and using ACCMetrics and CCMetrics for quantifying corneal nerve fibre length in mm/mm². Many studies lacked sufficient methodological details for reproducibility.

IVCM studies of corneal nerve fibres in diabetes show substantial methodological heterogeneity and inconsistent reporting, limiting reproducibility. We propose a guideline to support standardisation and improve the reliability of future research.
