Over the past 20 years, virtual reality (VR) has emerged in culture and healthcare providing a virtual world with audio and visual stimuli that can be immersive or non-immersive. Immersive VR has headsets with motion detectors that enable a multidimensional environmental experience with sensory feedback. Non-immersive VR provides a one-dimensional digital environment observed...

Transoral robotic surgery (TORS) is a minimally invasive technique for surgical removal of tumours of the tonsil and lateral oropharynx. Surgical defects after TORS lateral oropharyngectomy are traditionally left open to heal by secondary intention, resulting in significant postoperative pain and secondarily resulting in delayed swallowing and discharge. Although multimodal analgesia can improve postoperative pain control, no studies to date have assessed the impact of adjunct surgical interventions for reducing postoperative pain after TORS. Buccal fat rotation flap is a regional reconstruction option after TORS lateral oropharyngectomy and provides immediate coverage of the open surgical wound. However, the impact of buccal fat rotation flap reconstruction on postoperative pain and swallowing remains unclear. This trial aims to compare postoperative pain outcomes in patients who undergo TORS lateral oropharyngectomy with and without buccal fat rotation reconstruction.

This protocol outlines a single centre, parallel, unblinded, phase II, randomised control trial. Inclusion criteria include adult patient (≥18 years) undergoing TORS lateral oropharyngectomy for early to intermediate stage tonsillar squamous cell carcinoma (T1-2N0-1 p16+/–) or early to intermediate stage salivary gland tumours of the palatine tonsils. Exclusion criteria include a history of prior head and neck squamous cell carcinoma, prior head and neck radiotherapy, retropharyngeal lymphadenopathy, bilateral lymphadenopathy, need for bilateral neck dissection, baseline trismus, opioid use or drug addiction, need for open surgery (transcervical lateral oropharyngectomy), free tissue transfer, or alternative regional flap, and pregnancy. All patients are planned for a TORS lateral oropharyngectomy. The intervention group will have a buccal fat rotation flap reconstruction, and the control group will be allowed to heal via secondary intention. The allocation sequence will be created using a computer-generated random sequence with a permuted block strategy. The allocation sequence will be concealed until the time of assignment. The primary outcome is postoperative pain intensity during rest and swallowing using the visualised analogue scale. Secondary outcomes include postoperative complications, other adverse events, patient-reported speech and swallowing, opioid usage, length of hospital stay, feeding tube dependence and blood glucose levels. The trial has a target sample size of 40 patients. Statistical analysis of the primary outcome will be analysed in an intention to treat analysis using a linear mixed effects model.

The study was approved by the University Health Network Coordinated Approval Process for Clinical Research. Study number CAPCR ID: 24-5894. All participants will be required to provide written informed consent to participate. Findings will be presented at national conferences and published in medical journals.

Polysubstance use (PSU), particularly opioid-involved and stimulant-involved PSU, is a growing issue in the USA. PSU increases the risk of negative health consequences, including infectious diseases, worsening physical and mental health conditions, and overdose-related deaths. These consequences occur in the context of varying health risk behaviours, substance-related preferences, and treatment engagements among people with PSU. To inform improvements in prevention, harm reduction, and substance use disorder (SUD) treatment, additional research is needed to comprehensively understand the current context and drivers of PSU preferences, motivations, and behaviours.

Herein, we describe the protocol for a prospective cohort study designed to capture detailed patterns, profiles, and trajectories of PSU, with the aim of comprehensively examining the drivers of PSU behaviours and SUD treatment utilisation. Adults (ages 18–75; n=400) who engage in PSU will be recruited from healthcare institutions, an established participant database maintained by an adjacent SUD research team, and online advertisements. Study assessments will capture dynamic patterns, choice preferences, and motivators of PSU via behavioural economic (BE) measures, detailed Timeline Follow-Back (TLFB) interviews, and self-administered surveys. The assessment timeline will include a baseline survey and TLFB interview, weekly TLFB interviews for 4 weeks post-baseline, and follow-up surveys and TLFB interviews at 4-, 8-, and 12-months post-baseline.

The study is funded through the National Institutes of Health Helping to End Addiction Long-term (HEAL) initiative and was approved by the University of Michigan Medical Institutional Review Board. Findings will be disseminated to academic, clinical, and community partners through the Michigan Innovations in Addiction Care through Research and Education programme. Results from this study will inform actionable and practical insights relevant to the delivery of personalised care in the context of PSU.

Police are frequently dispatched to a wide range of 911 calls, including mental and behavioural health crises, despite lacking the training, resources and time to respond effectively. In particular, people with serious mental illness are at elevated risk of experiencing excessive use of force, arrest and continued criminal legal involvement following police contact. Following the murder of George Floyd and other highly publicised police killings, Community Safety Response (CSR) programmes, staffed by unarmed peers, mental health professionals and other trained responders, have proliferated to provide non-police responses to mental and behavioural health and other quality-of-life concerns. CSR programmes have expanded rapidly, yet the evidence base remains fragmented and largely outside the peer-reviewed literature.

This scoping review will synthesise peer-reviewed and grey literature from 2020 to present on CSR programmes operating in North America. Guided by Joanna Briggs Institute methodology and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) standards, we will search multiple databases (Medline, PsycINFO, Embase, SocIndex, Web of Science, Policy Commons) and employ complementary grey literature search strategies, including targeted website searches, reference tracking and review of internal and external reports and evaluations. Inclusion criteria require that programmes provide non-police first response to calls traditionally served by law enforcement and include information on programme operations or outcomes. Two reviewers will independently screen and extract data on process metrics including operational characteristics, dispatch, funding, services provided and outcomes such as populations served, diversion from police, service linkage and use of force.

No ethical review for this study is required as it will not include human subjects or any identifiable information. Findings will provide the first national synthesis of CSR programme models, operations and outcomes. Results will inform policy-makers, practitioners, researchers and community members. Findings will be disseminated through peer-reviewed publications and public-facing products to support implementation, scale-up and sustainability of CSR programmes.

Genitourinary syndrome of menopause (GSM) is a prevalent condition among breast cancer survivors, often exacerbated by oncological treatments. Hormonal therapies are typically contraindicated in this population, necessitating effective non-hormonal interventions.

This randomised controlled trial aims to compare the effectiveness and cost-effectiveness of multimodal pelvic floor physiotherapy—comprising pelvic floor muscle training, non-ablative radiofrequency, therapeutic pelvic health education and the use of vaginal moisturisers—versus fractional CO₂ laser therapy combined with vaginal moisturisers in alleviating GSM symptoms in breast cancer survivors. Participants will be randomly assigned to one of the two intervention groups. Primary outcomes include measures of sexual function (assessed by the Female Sexual Function Index), subjective pelvic perineal pain intensity (measured with a 100 mm Visual Analogue Scale) and health-related quality of life (assessed by the Functional Assessment of Cancer Therapy-Breast), assessed at baseline, post-intervention and at 3, 6 and 12 months of follow-up. Statistical analyses will be conducted to evaluate the clinical efficacy and cost-effectiveness of the interventions.

The study protocol has been approved by the Ethics and Health Research Committee of the University of Alcalá (Reference: CEIP/2024/1/012). All participants will provide informed consent prior to inclusion in the study. Findings will be disseminated through peer-reviewed journals and conference presentations, and by engaging with patient associations and survivor groups through tailored materials.

Cancer screening appointments are an opportunity to encourage positive behavioural changes. Up to 80% of cancer screening attendees are open to discussing physical activity during cancer screening, but some say this would deter them from future screening. This study aimed to gain an in-depth understanding of individuals’ receptivity to physical activity advice at cancer screening.

Interview-based qualitative study.

The study was conducted from May 2017 to September 2018 in the UK. Participants were recruited using adverts on two university campuses, Facebook and a participant recruitment agency. To be eligible, participants had to have an upcoming cancer screening appointment within 2 weeks. There were 30 participants.

Participants recorded their receptivity to physical activity advice in the days before and after screening. Data-prompted semi-structured interviews explored these responses. Interviews were analysed using a thematic framework analysis.

Participants felt discussing physical activity at cancer screening would be relevant. However, participants experienced anxiety related to the screening process which could increase or decrease their receptivity. Participants felt if information was delivered in a judgemental way, it could negatively impact future screening participation.

Screening attendees’ receptivity could be influenced by the timing of a discussion and by their levels of anxiety throughout screening. Participants’ anxiety during screening can either reduce their ability to engage in a discussion or increase the relevance of the discussion. The communication style of the healthcare practitioner was key for why some screening attendees could be deterred from future cancer screening.

In low-income and middle-income countries, significant geographical and socioeconomic inequalities affect access to eye care. This study explores an equity-focused approach to improve access to eye care services provided by a community-based eye care organisation in northern India.

A sequential exploratory mixed-method approach.

A high-volume eye screening programme in north Indian villages. Individuals identified with eye care needs during the screening were referred to the six nearby primary eye care centres.

7578 individuals identified with eye needs through a community-based eye screening programme. Of these, 4431 (58.6%) were women and 3137 (41.4%) were men.

Socioeconomic questions, developed by experts and lay representatives, were integrated into an ongoing digitally supported (Peek Vision) eye screening programme in north Indian villages. Data from referred individuals identified with eye needs were analysed using logistic regression with a mixed-effect model to identify socioeconomic characteristics most strongly associated with poor access to care after referral. A sequential exploratory mixed-method approach, including in-person interviews and follow-up telephonic surveys of individuals with these characteristics, was used.

To identify barriers and gather suggestions for improving attendance from groups least likely to attend services.

Of 7627 individuals referred for eye care, 7578 (99.3%) participated in the study. Of those, 2937 (38.5%) attended the Vision Centre, to which they were referred. The least likely to attend were individuals aged >16, those with dependents, and those referred for non-cataract conditions. Among the 3939 individuals with all three characteristics, the attendance rate was 35.3% compared with 42.5% (p

Suggested programme improvements, including better counselling, reminder calls and transportation, could increase access among those least likely to access services after referral. This study demonstrates a two-step approach for identifying solutions from individuals facing the most significant barriers to care. We will go on to conduct trials of these suggested interventions.

Implementation science research increases the uptake of evidence-based interventions, which may improve health equity among racial and ethnic minorities. However, it is unclear how anti-racism and anti-colonialism practices have been integrated into implementation science research. The objectives of this scoping review are to describe the current conceptualisations of racism and colonialism within the USA, examine racism or colonialism-conscious approaches and analyse gaps in the operationalisation of anti-racism or anti-colonialism within implementation science studies.

This scoping review will be conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for scoping reviews guidelines. The Center for Chronic Disease Reduction and Equity Promotion Across Minnesota conceptual framework and an implementation science anti-racism lens will guide the study design and analysis. To determine study eligibility for the scoping review, articles will undergo abstract and full-text screening by two independent reviewers and discrepancies will be settled together. Data charting will be extracted from included articles by eight independent reviewers. The search strategy will use controlled vocabulary and natural language keywords related to health equity, health disparities and anti-racism/colonialism on six databases. The scoping review will include studies that applied implementation science theories, models or frameworks among US-based populations. Additionally, included studies will report any of the following implementation activities: implementation strategies, implementation outcomes, adaptations to evidence-based interventions, or evaluations of pre-implementation or implementation context.

No ethical approval was required for the scoping review. Dissemination will be through publication in a peer-reviewed journal and conference presentations.

Fibrosis is a pathological feature that can occur in a wide range of diseases including diabetes mellitus. We investigated whether in people with type 1 (T1DM) or type 2 diabetes mellitus (T2DM), glycaemia or diabetes-related complications are associated with fibrotic diseases.

Retrospective cohort study using UK Clinical Resource Datalink (CPRD) Aurum and Hospital Episode Statistics.

We included people with prevalent T1DM or T2DM as of 31 December 2015 (recorded in CPRD Aurum), eligible for linkage with Hospital Episode Statistics and followed up for 3 years.

We defined diabetes status using blood/urine biomarkers and complications. In the T2DM cohort, we also investigated exposures of hyperglycaemia, insulin resistance and metformin prescription. Fibrotic condition diagnoses were determined from both primary and secondary care records. Logistic regression analyses were undertaken to understand the strength of association between diabetes status/diabetic complications and fibrotic conditions, respectively.

The T1DM cohort consisted of 9669 people while the T2DM cohort included 504 066 people. In T1DM, we found that albuminuria was associated with lung fibrosis (ORadj: 2.07, 99% CI 1.35 to 2.17), and microvascular complications were associated with atherosclerosis (ORadj: 1.81, 99% CI 1.18 to 2.77) and cardiomyopathy (ORadj 1.53, 99% CI:1.15 to 2.04). In the T2DM cohort, both glycaemia above target and diabetes complications were associated with most fibrotic conditions.

Within the T1DM population, no consistent association between diabetes status and all fibrotic diseases was observed. More research is required to understand whether the association between diabetes complications and fibrotic diseases is due to shared risk factors or whether glycaemia in T2DM may be influenced by fibrotic pathology.

Vitamin D deficiency during pregnancy is a global health concern, contributing to adverse maternal and fetal outcomes. Despite its importance, limited data exist on vitamin D status and its determinants among pregnant women in Ethiopia. This study aimed to assess the prevalence and determinants of vitamin D deficiency among pregnant women in their first and second trimesters in Gondar Town, Ethiopia, 2024.

A facility-based cross-sectional study was conducted at the antenatal care unit of University of Gondar Comprehensive Specialized Hospital from January to March 2024.

Eligible participants were selected using a simple random sampling technique. Sociodemographic, behavioural and clinical data were collected through structured questionnaires and medical record reviews. Serum levels of vitamin D, calcium and alkaline phosphatase were analysed using the Beckman Coulter clinical chemistry analyser. Statistical comparisons between pregnant women in the first and second trimesters were performed using the independent t-test. Determinants of vitamin D deficiency were identified using multivariate logistic regression analysis.

384 pregnant women in their first or second trimester.

The prevalence of vitamin D deficiency (90 mm Hg) (AOR 0.28, 95% CI 0.11 to 0.70), lower dietary diversity (AOR 3.17, 95% CI 1.13 to 8.89), lower fish and fish oil consumption habit (AOR 3.01, 95% CI 1.03 to 8.77; AOR 12.27, 95% CI 1.50 to 100.42) were the key predictors associated with serum vitamin D defiency.

Nearly half of the pregnant women in Gondar Town exhibit vitamin D deficiency, showing a challenging public health concern. Thus, targeted interventions, such as dietary supplementation and lifestyle modifications, are urgently needed to address the problem and improve maternal and neonatal health outcomes.

Eating disorders are complex mental health conditions characterised by pathological behaviours related to food intake, often accompanied by a chronic obsession with weight control. Their prevalence is increasing, with an earlier onset and greater severity among young people. Universal prevention, through multicomponent strategies that tackle modifiable risk factors, has emerged as a promising tool. This paper reports the study protocol designed to assess the effectiveness and cost-effectiveness of the PRETA (Prevención de los Trastornos de la Alimentación) programme in reducing the risk of eating disorders and related modifiable risk factors among preadolescents in the school setting.

The PRETA programme will be assessed by means of an open, community-based, multicentre, controlled trial using 1:1 matched-pairs cluster randomisation at the school level. Schools in Tenerife (Spain) will be assigned to the PRETA programme or a waitlist control group. Participants include 5th- or 6th-grade students (10–13 years old), their parents and teachers. The PRETA programme is a universal, school-based, multicomponent programme designed to reduce eating-disorder risk and modifiable risk factors. Its main component is an interactive online platform called e-PRETA, complemented by training sessions for families and teachers. e-PRETA includes nine 45-minute sessions addressing risk factors, such as dietary habits, beauty standards, media literacy, self-esteem, emotional regulation and social skills. A total of 1068 children from 12 schools will participate. The primary outcome will be the risk of developing eating disorders (Children’s Eating Attitudes Test-26 item version). Secondary outcome measures are body dissatisfaction (Adapted Contour Drawing Rating Scale), eating disorder traits (Eating Disorder Inventory-2), internalisation of appearance ideals (Sociocultural Attitudes Towards Appearance Questionnaire-4) and self-esteem (Rosenberg Self-Esteem Scale). Outcomes will be assessed at baseline and postintervention (3 months). Additional baseline covariates such as electronic device use, parental feeding attitudes, physical activity, sleep duration and screen time will also be collected. Programme effectiveness will be analysed using generalised mixed models. Cost-effectiveness will be assessed by comparing the incremental costs associated with the implementation of the PRETA programme with its estimated effectiveness.

Ethics approval has been obtained from the Ethics Committee for Research with Medicines at the University Hospital of the Canary Islands (CHUC_2021_78). Written informed consent will be obtained from the parents or legal guardians of all participants. Results will be disseminated through scientific publications and conferences.
