Music-based training programmes, such as learning how to play an instrument or sing in a choir, have been suggested as potential interventions for promoting healthy brain ageing in older adults at risk of cognitive decline because of their ability to enhance cognitive functions and potentially promote neuroplasticity. However, there is limited empirical evidence in older adults at risk of dementia, especially that evaluates both piano and singing interventions and their effects on cognition and neuroplasticity. In this protocol, we outline a study to assess the efficacy of keyboard and singing music training programmes on reducing cognitive decline and other outcomes in older adults with Mild Cognitive Impairment (MCI).

This randomised, single-blind, controlled, parallel-group trial aims to enrol 432 individuals with MCI from the community in Sydney, Australia. Participants are randomly allocated to participate in either keyboard lessons, singing lessons or a film discussion control group once a week for 3 months. The primary objective is to assess the effectiveness of two music training programmes (keyboard and choral singing) for enhancing verbal memory after 3 months compared with control. Additionally, we will examine how these music-based interventions affect other aspects of cognition, mood, sleep, overall well-being, markers of brain plasticity and blood biomarkers of Alzheimer’s disease and neurodegeneration. Tertiary objectives are to identify factors that impact the success of the interventions, such as participation rates, engagement levels and key demographic and clinical features. Outcomes are collected at baseline and at 3 and 9 months. The primary endpoint analysis will include all randomised participants to estimate the treatment effect using intention-to-treat principles. Primary and secondary outcomes will be analysed using linear mixed models and effect size measures will be calculated.

This study will be the first robust, randomised controlled trial to assess the potential and relative value of music engagement for cognitive decline in high-risk MCI individuals, as well as broader effects on other markers of mental health, well-being and neurodegeneration. Co-designed with implementation in mind, the music interventions can potentially be delivered within memory clinic or community settings.

The Sydney University Human Research Ethics Committee (2023-026) has approved this protocol. The trial findings will be shared through conferences, publications and media.

Epilepsy prevalence varies widely across Nigeria, with rates ranging from 3.1 to 37.0/1000 population. There have been no studies on epilepsy prevalence and treatment gap in the Northeast Region of Nigeria. This study aimed to study epilepsy prevalence and the epilepsy treatment gap (ETG) in an urban and a rural community in Northeast Nigeria.

Cross-sectional, community-based survey.

Epilepsy screening of residents in two communities in Northeast Nigeria using a WHO screening tool and a validated study questionnaire from 1 March to 10 June 2022.

8599 community residents aged ≥2 years.

Prevalence of epilepsy, active epilepsy, ETG and associated factors.

We screened 8599 residents, of whom 88 had epilepsy. Crude epilepsy prevalence was 10.2 per 1000 and was three times higher in the rural than in the urban community (18.5 vs 6.4; ²=26.79, p2=0.087, p=0.768). Logistic regression analysis showed that the ETG was associated with a lack of counselling (OR 15.8, 95% CI 3.5 to 70.7, p

The prevalence of epilepsy in Bauchi State was within the range reported in Nigeria but three times higher in the rural than in the urban community. A high ETG was associated with poor counselling of people with epilepsy. Epilepsy counselling, health education and wider access to neurology services could reduce the burden of epilepsy in Northeast Nigeria.

To construct a data-driven composite from (a subset of) currently used quality indicators for oesophagogastric cancer surgery and to evaluate whether this approach enhances the reliability of between-hospital comparisons on outcome relative to the expert-driven composite indicator ‘textbook outcome (TO)’.

In this retrospective cohort study, we applied Item Response Theory (IRT) to construct a data-driven continuous composite indicator reflecting a single latent variable—the quality of surgical care—and estimated latent variable scores for all individual patients. Reliability was compared between the expert-driven (TO) and data-driven (IRT) composite indicators.

All Dutch hospitals providing oesophagogastric cancer surgery.

All patients who underwent oesophagectomy (n=3588) or gastrectomy (n=1782) between 2018 and 2022 as registered in the Dutch Upper GI Cancer Audit (DUCA).

We evaluated the reliability of between-hospital comparisons using ‘rankability’, which quantifies the proportion of observed variation in indicator scores between hospitals not attributable to chance.

Seven out of 15 quality indicators were included in the IRT composite indicator. Most of the patients were assigned the artificial maximum of the continuous quality score (ie, ceiling effect), resulting in similar average hospital scores. Relative to TO, rankability increased when using the IRT composite for oesophagectomy (57% vs 41%) but declined for gastrectomy (38% vs 47%).

The selected seven quality indicators for oesophageal and gastric cancer surgery represent a single latent variable but are not yet optimal for differentiating surgical care quality due to ceiling effects. Despite using fewer indicators, the continuous IRT score showed a promising increase in rankability for oesophagectomy, suggesting that data-driven composite indicators may enhance hospital benchmarking reliability.

Diabetic foot ulcers (DFUs) are highly prevalent and recurrent complications of diabetes mellitus that have significant health and cost implications. Self-care is critical for preventing or delaying DFU and promoting healing, yet adherence to self-care recommendations is low. Interventions using motivational interviewing (MI) have been effective in supporting behaviour change and emotional adjustment, but evidence for DFU is scarce. This study will assess the acceptability, feasibility and preliminary efficacy of an MI-guided programme, Healing DFU through Empowerment and Active Listening (HEALing), and its integration in usual wound care practice.

This single-arm pilot study adopts a mixed-methods approach to assess the feasibility and acceptability of the HEALing intervention. HEALing is a practical, low-intensity, clinic-integrated personalised self-care support intervention, comprising three 30 min face-to-face sessions delivered over 6 weeks by trained wound care nurses, aiming to enhance self-care behaviours and support emotional adjustment in patients with DFU. Data will be collected from a battery of questionnaire-based surveys with patients (n=30), and in-depth individual interviews with both patients (n=30) and wound care nurse facilitators (n=10) from nurse-led wound clinics in a large primary care sector in Singapore.

The primary feasibility outcomes will include enrolment, retention (≥80%), data completion (≥80% of surveys) and participant satisfaction. Secondary outcomes will include self-report measures of illness perceptions, foot care confidence, diabetes distress, foot self-care behaviour, DFU knowledge, autonomy support and health-related quality of life, taken at baseline and post-intervention. Post-intervention interviews with patients and wound care nurse facilitators will be conducted to collect feedback on the programme and its implementation feasibility.

The study protocol has been approved by the local ethics committee, and written informed consent will be obtained from all participants. Findings will be disseminated through the first author’s PhD thesis, peer-reviewed journals, national and international conferences and public events.

Squamous cell carcinoma and multiple actinic keratoses caused by solar ultraviolet radiation (UVR) are among the most frequently recognised occupational diseases in Germany. Employees who regularly work outdoors, for example, in the construction industry, agriculture, forestry and gardening, are at a higher risk of developing occupational skin cancer. However, sun-safety behaviour in outdoor workers is currently insufficient. Therefore, this study aims to investigate the effectiveness of an intervention to increase sunscreen use among outdoor workers.

In this non-randomised, controlled intervention study, 234 outdoor workers from different companies in industries with outdoor working activities based in Germany will be included. The study population, aged 18 years and above, has to be intensively exposed to solar UVR of regularly 1 hour or more per day. The intervention group will receive a sunscreen package as well as health education. The control group follows the practice in their companies (‘treatment-as-usual’). At the beginning of the study, after 3 months and at the end of the study (after 6 months), both groups filled in different questionnaires. In addition, stratum corneum (SC) samples will be collected at the beginning and after 3 months. The primary outcome—increase in the frequency of sunscreen use during work and in leisure time—will be assessed from data on self-reported sunscreen use. The secondary outcomes include sun protection behaviour, knowledge about sun protection and skin cancer, and acceptance of the provided sunscreens. Further secondary outcomes include internal UV dose and UV-related immune response, determined by the levels of SC biomarkers. Data will be analysed using both descriptive and inferential methods.

The study protocol followed the principles of the Declaration of Helsinki (2013) and was approved by the Ethics Committee of Osnabrück University, Germany (reference Ethik-37/2024). Study results will be disseminated through peer-reviewed publications and conference presentations.

Despite the important role of healthcare services in trauma recovery, many survivors of violence do not seek help. This study aims to examine rates of healthcare utilisation, including differences for physical violence versus rape, gender and physical injury (vs no injury) and obstacles to seeking care within 6 months following incidents of physical violence and rape.

The participants were randomly chosen from the National Population Registry in Norway and invited to participate in a telephone survey on violence exposure and health between June 2021 and June 2022 (N=4299, 49% women).

The sample included 1768 violence-exposed individuals. Of the women (n=749), 82.1% had experienced physical violence and 40.3% had experienced forcible rape. Of the men, most had experienced physical violence (98.6%) and a small percentage had experienced rape (3.5%).

Logistic regression models were used to investigate whether healthcare seeking differed by gender, type of violence (rape vs physical violence) and severity (physical injury). Barriers to accessing healthcare were also investigated using descriptive statistics and content analysis.

Healthcare seeking rates were low after rape (16.9%) and physical violence (24.2%), with somewhat higher rates among individuals experiencing both types of violence (39.9%). There were no statistically significant differences in the odds of healthcare utilisation between the three types of violence exposures when we controlled for gender, physical injury, violence characteristics and sociodemographic factors. Men were more likely than women to have sought healthcare (adjusted OR (aOR): 1.37, 95% CI: 1.02 to 1.85, p=0.042). Physical injury was strongly associated with greater healthcare utilisation (aOR: 6.39, 95% CI: 4.85 to 8.41, p

Few victims seek healthcare shortly after experiencing rape or physical violence. Quantitative and qualitative findings indicate that many seek healthcare exclusively for severe physical injury. These results emphasise the need to improve health services’ outreach to victims of violence, who are at heightened risk of mental health issues and chronic illnesses.

COVID-19 in children is generally of short duration, but some may take longer to recover. This study investigated the time to symptom resolution following SARS-CoV-2 infection among children in a community setting on the outskirts of an urban centre in Brazil.

Prospective cohort study.

This is a community-based cohort of children living in Manguinhos, a favela in Rio de Janeiro. The cohort was followed through home visits and telephone monitoring of symptoms. The analysis focused on symptomatic children from this cohort with confirmed SARS-CoV-2 infection. Recovery time was defined as the interval between the first date with symptoms and the first date without symptoms following a positive SARS-CoV-2 test.

A total of 1276 children (boys and girls aged 2–

COVID-19 recovery time, assessed based on change points on the symptom persistence probability curve (Kaplan-Meier).

Among children who tested positive, 148 (60%) were symptomatic. The median recovery time was 11 days (IQR: 7–16). Two inflection points were identified on the Kaplan-Meier curve: days 16 and 34. Children who were ill during the Omicron wave took longer to recover. More boys became asymptomatic within the first 15 days; about 93% of girls recovered by day 33, and boys were more common among those who recovered in ≥34 days. Children aged 6–

Among children from a vulnerable area in Rio de Janeiro, recovery time was longer than that reported in other countries, with 9.5% of children experiencing persistent symptoms for more than 33 days. These findings are crucial for understanding the implications of COVID-19 in specific socioeconomic contexts and the dynamics of paediatric recovery in community settings.
