Background: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals are at higher risk of poor mental health and well-being. Social media platforms can provide LGBTQ youths with a space that counters heteronormative environments and potentially supports mental health and well-being. Mental health includes an individual’s state of psychological and emotional well-being and not merely the absence of mental disorders. Objective: We sought to identify how LGBTQ youths and adolescents use social media for connection with other LGBTQ peers and groups, identity development, and social support and how these affect mental health and well-being. Methods: PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) procedures were used to guide this review. Searches were conducted in ACM Digital Library, CINAHL, Ovid Embase, Ovid MEDLINE, and Web of Science in March 2021. This review focused on LGBTQ youths aged 10 to 24 years. Included peer-reviewed studies must comprise social media; explore peer connection, identity development, or social support; and be published from 2012 onward. In total, 2 researchers extracted data and performed quality assessments independently using the Newcastle-Ottawa Scale for quantitative articles and the Critical Appraisal Skills Programme for qualitative articles. Qualitative synthesis was performed on articles that satisfied the eligibility criteria. Results: A total of 26 studies (n=15, 58% qualitative; n=8, 31% quantitative; n=3, 12% mixed methods) met the inclusion criteria. Of the 8 quantitative studies, 6 (75%) were cross-sectional, and 2 (25%) were cohort studies. All studies ranged from moderate to high quality. Social media was a popular tool used by LGBTQ youths to connect with LGBTQ communities. In qualitative data, we found that LGBTQ youths negotiated and explored identity and obtained support from peers on social media. Instagram, Tumblr, and Twitter were commonly used to access LGBTQ content owing to ease of anonymity. Identity management was the most studied social media affordance, important to LGBTQ youths for strategic disclosure. Key strategies for managing identities included being anonymous, censoring locations or content, restricting audiences, and using multiple accounts. Quantitative studies (3/8, 38%) showed that social media was associated with reduced mental health concerns and increased well-being among LGBTQ youths. Mental health concerns arising from social media use were attributed to discrimination, victimization, and policies that did not accommodate changed identities. Conclusions: We found that social media may support the mental health and well-being of LGBTQ youths through peer connection, identity management, and social support, but findings were limited by weaknesses in the evidence. More robust and longitudinal studies are needed to determine the relationship between social media use and LGBTQ mental health, particularly among adolescents. The findings may inform interventions to promote social media health literacy and the mental health and well-being of this vulnerable group.

Background: Adolescents use social media more frequently than other age groups. Social media has been described as a safe environment for lesbian, gay, bisexual, transgender and queer and/or questioning (LGBTQ) adolescents. As part of mixed-methods research investigating the association between social networks and sexual agency, we present qualitative findings on how LGBTQ adolescents connect online to form support networks. Methods: We recruited 30 adolescents aged 14–17 years who identified as LGBTQ in terms of their gender or attraction in the longitudinal Social Networks and Agency Project. Semi-structured interviews were conducted online or face-to-face across Australia. Thematic analysis was used to explore perceptions and experiences of participants in relation to social media use and relationships. Results: Two overarching themes were identified: LGBTQ adolescents use social media for identity, relationships and wellbeing support. Social media is not always free of discrimination for LGBTQ adolescents. Many LGBTQ participants joined Facebook groups to connect with LGBTQ peers. Facebook was considered a vital support for those with mental health concerns including suicidal ideation. Participants gave and received support from group members, which was considered useful for those feeling isolated or victimised. LGBTQ adolescents formed friendships, romantic relationships and gained information on sex, relationships, and sexual health from these groups. Participants described negative experiences including discrimination within Facebook groups, mismanaged groups and exposure to anti-LGBTQ sentiments. Conclusion: Social media is an environment where LGBTQ adolescents can connect, educate and support each other, which may have beneficial effects for this marginalised group. There remain issues with social media including discrimination against and within LGBTQ communities.

Background Microarray patches (MAPs) deliver vaccines to the epidermis and the upper dermis, where abundant immune cells reside. There are several potential benefits to using MAPs, including reduced sharps risk, thermostability, no need for reconstitution, tolerability and self-administration. We aimed to explore and evaluate the immunogenicity, safety, usability and acceptability of MAPs for vaccination. Methods We searched CINAHL, Cochrane Library, Ovid Embase, Ovid MEDLINE and Web of Science from inception to January 2023. Eligibility criteria included all research studies in any language, which examined microarrays or microneedles intended or used for vaccination and explored immunogenicity, safety, usability or acceptability in their findings. Two reviewers conducted title and abstract screening, full-text reviewing and data extraction. Results Twenty-two studies were included (quantitative=15, qualitative=2 and mixed methods=5). The risk of bias was mostly low, with two studies at high risk of bias. Four clinical trials were included, three using influenza antigens and one with Japanese encephalitis delivered by MAP. A meta-analysis indicated similar or higher immunogenicity in influenza MAPs compared with needle and syringe (N&S) (standardised mean difference=10.80, 95% CI: 3.51 to 18.08, p<0.00001). There were no significant differences in immune cell function between MAPs and N&S. No serious adverse events were reported in MAPs. Erythema was more common after MAP application than N&S but was brief and well tolerated. Lower pain scores were usually reported after MAP application than N&S. Most studies found MAPs easy to use and highly acceptable among healthcare professionals, laypeople and parents. Conclusion MAPs for vaccination were safe and well tolerated and evoked similar or enhanced immunogenicity than N&S, but further research is needed. Vaccine uptake may be increased using MAPs due to less pain, enhanced thermostability, layperson and self-administration. MAPs could benefit at-risk groups and low and middle-income countries.

Introduction: Mpox emerged as a multi-country outbreak in 2022 and disproportionately affected gay, bisexual, and other men who have sex with men (GBMSM). Stigma is known to exacerbate health crises by discouraging testing, treatment, and vaccination. This review aimed to explore stigma associated with Mpox among GBMSM from July 2022, when mpox was declared a public health emergency of international concern. Methods: The PICO framework guided this narrative review. A search was conducted across the following databases from inception to June 2025: PubMed/MEDLINE, Embase, CINAHL, and Web of Science. The literature had to be empirical, peer-reviewed research that focused on mpox-related stigma in GBMSM. Results: Forty-seven studies were included in this review. The following themes were derived: (1) healthcare experiences, (2) media influence, (3) internalised and anticipated stigma, (4) public health messaging, (5) community responses, and (6) psychosocial impact. Healthcare experiences were marked by anticipated discrimination; many GBMSM delayed testing or vaccination for fear of being disclosed or labelled promiscuous. This was especially apparent in contexts where same-sex relationships are criminalised, leading some men to self-medicate or seek clandestine services. Media analyses revealed that social and traditional platforms often amplified blame and homophobia, though community-led counter-messaging helped shift narratives. Internalised and anticipated stigma resulted in shame, concealment of symptoms, avoidance of care, and heightened anxiety. Public health messaging that framed mpox as a behaviour-linked rather than identity-linked risk was more acceptable, and flexible vaccination strategies (e.g., offering less conspicuous injection sites) increased uptake. Stigma contributed to psychosocial distress and may have impeded outbreak control. Conclusions: Mpox-related stigma among GBMSM operates at individual, community, and structural levels, echoing patterns from the HIV era. Effective mitigation requires rights-based, destigmatising communication, culturally competent care, and collaboration. Addressing stigma is vital to controlling future outbreaks and ensuring equitable healthcare access.

Vaccination is crucial for public and population health. Microarray patches (MAPs) could enhance vaccine uptake through reduced pain, no needles, improved thermostability and self or lay administration, but there is limited evidence. We aimed to investigate the perceptions of the general public and healthcare professionals (HCPs) aged 18 years and older about MAP vaccination. This mixed-methods study was part of a project to validate a scale measuring MAP vaccination's safety, usability, and acceptability. Online surveys and semi-structured interviews were conducted in Australia, Canada, United Kingdom, and New Zealand. 7-point Likert scale items were scaled from "strongly disagree" to "strongly agree" and analysed using descriptive statistics (e.g., means and confidence intervals (CI)). Interviews were transcribed verbatim, coded, and analysed using thematic analysis. In the survey group, 403 general public and 184 HCPs responded. We interviewed 27 participants (12 general public and 15 HCPs). The general public and HCPs perceived MAPs as safe and efficacious, with means of 5.00 (95 % CI: 4.85-5.14) and 4.92 (95 % CI: 4.71-5.12) respectively. The general public (mean = 5.58, 95 % CI: 5.46-5.70) and HCPs (mean = 5.75, 95 % CI: 5.59-5.92) perceived MAPs as usable. Lastly, the general public (mean = 5.49, 95 % CI: 5.37-5.61) and HCPs (mean = 5.30, 95 % CI: 5.12-5.50) perceived MAPs as acceptable. Participants widely perceived MAPs as safe and easy to use due to their 'straightforward' instructions, including for self-administration. All participants regarded MAPs as advantageous for children and needle-phobic individuals. Some HCPs were concerned about possible adverse events at home (i.e., anaphylaxis), but were interested in incorporating MAPs in their clinical practice. Microarray patches (MAPs) MAPs are viewed by the general public and HCPs as safe, user-friendly, and well-received as alternatives to needle and syringe vaccination for greater acceptability among consumers. MAPS may also improve access to vaccination in priority populations and areas with limited resources.
