Breast cancer is the most common cancer among women globally. While the impact of lifestyle factors like smoking and obesity on breast cancer risk and survival is well documented, the effect of working conditions is not fully understood. Moreover, breast cancer can reduce employability, making it crucial to identify factors that facilitate return to work and improve life satisfaction. Since breast cancer is affected by sleep and lifestyle, which are related to working conditions, understanding how they affect breast cancer outcomes is key. This study aims to explore the relationship between working conditions and breast cancer outcomes, including incidence, mortality and survival within a causal framework. Our specific aims are to understand the relationship between (1) working conditions and occupational groups and breast cancer outcomes, including the extent to which sleep, lifestyle and breast cancer screening uptake explain these relationships and (2) prediagnosis working conditions, sleep and lifestyle and their effect on return to work and life satisfaction among breast cancer survivors.

We will use data from the UK Biobank, a large-scale cohort study with data on 273 825 women between 40 and 69 years old at baseline, followed from 2006 to 2022. The data has been linked with death and cancer registries and includes 8309 incident breast cancer cases. To quantify the effect of working conditions on breast cancer outcomes (aim 1) and their effect on return to work and life satisfaction (aim 2), we will implement g-methods to estimate the average causal effect and employ counterfactual-based mediation analysis to quantify how much mediating factors, such as sleep and lifestyle, explain this effect.

UK Biobank received ethical approval from the North West Multi-Centre Research Ethics Committee. No further ethical approval was required for the proposed research project. In line with the two aims, four original research manuscripts will be published in open-access peer-reviewed journals to disseminate the findings. In addition, findings will be disseminated at international conferences and scientific meetings.

Mental health issues such as depression and anxiety are highly and disproportionally prevalent among university students. Beyond the academic rigour, stressors imposed by a new environment result in them being vulnerable to the onset and manifestation of mental health symptomatology. Leveraging smartphones and wearables for digital phenotyping capabilities is an innovative approach for monitoring and intervening in the mental health conditions of university students. This provides a unique opportunity to collect and identify digital and behavioural biomarkers, subsequently enabling the development of predictive models to identify university students at risk.

This study—Brightline—will employ an observational study design over a 6-month period, recruiting 500 students from a major public university in Singapore. Passive data collection will occur continuously throughout the monitoring period through a wearable device (Fitbit Charge 6) and smartphone sensors via the Brightline app, which uses a digital phenotyping data collection platform. Active data collection will consist of self-report questionnaires to be completed at the beginning of the study and follow-up assessments at 1, 3 and 6 months after. The passive and active data collected will be analysed to identify the digital biomarkers associated with depression, anxiety, stress, loneliness and affect among university students. Predictive models of these mental health issues will also be developed.

This study was approved by the Nanyang Technological University Institutional Review Board (IRB-2023-894). Findings from this study will be published in peer-reviewed journals and presented at academic conferences.

Diabetes mellitus (DM) and depression commonly coexist. Each condition increases the risk of developing the other and adversely affects treatment outcomes. Such complex interactions of diseases, referred to as syndemics, have not been well studied. This study aims to assess the syndemics of depression, sick role and activation status among newly diagnosed adults living with DM.

A prospective 6-month follow-up study will be conducted with 485 participants. Depression will be assessed with the 9-item Patient Health Questionnaire, applying a cut-off score of 10. The primary outcome will be glycaemic control, and the secondary outcomes will be health-related quality of life (HRQoL) and functional disability status. Depression, the primary outcome and the secondary outcomes, will be measured at baseline, 3 months and 6 months. The sick role, activation status and health system perspectives will be explored using qualitative methods following the second measurement. Data will be collected from adults living with DM, healthcare providers and healthcare managers. Qualitative sampling will continue until data saturation is reached.

Quantitative analysis will be done using STATA V.17. The prevalence of depression will be determined at baseline. Associated factors will be analysed using Poisson regression with a robust variance estimator. Incidence rate of depression, glycaemic control, HRQoL and disability status will be measured at 3 and 6 months. A multilevel mixed-effects generalised linear model will be fitted, with the three measurement time points nested within individuals, and individuals nested within health institutions. Qualitative data will be analysed thematically using NVivo V.12 software.

Ethics approval has been granted by the institutional review board of Bahir Dar University (protocol number 3098/25). Findings will be disseminated through peer-reviewed publications, conference presentations and local channels for community audiences.

The mental health of people living with HIV (PLWH) is a growing concern globally, particularly in sub-Saharan Africa (SSA), where there is limited access to mental healthcare, with evidence showing high levels of depression, anxiety and neurocognitive disorders among this population. While Mental Health Disorders (MHDs) can impede HIV care and promote adverse health outcomes, there is limited literature on MHDs among PLWH. This scoping review will explore the existing literature on the burden and factors associated with MHDs among adults living with HIV in SSA.

Arksey and O’Malley’s methodological framework will guide the search of this scoping review. Relevant original research articles published in English from 1 January 2000 to 31 May 2025 on MHDs among PLWH in SSA will be identified through searches in the African Index Medicus, African Journal Online, PubMed and Embase databases. Four independent reviewers, working in pairs (one reviewer and one verifier), will screen the titles, abstracts and later the full texts, adopting the population, concept and context framework. Other coauthors will serve as tiebreakers whenever there is disagreement on the eligibility. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews flowchart will be presented. We will perform a narrative synthesis to report our findings.

This scoping review protocol does not require ethical approval, as it relies solely on publicly available existing data and does not involve human participants. We will disseminate the findings from this review through peer-reviewed publications and presentations at local and international conferences.

The protocol was registered in the Open Science Framework (https://osf.io/8ymqu).

Frontotemporal lobar degeneration (FTLD) is the second most common early-onset dementia. Several studies demonstrated that neuroinflammation and iron accumulation occur in FTLD. However, the timing and relevance of these processes and whether these two are merely cause or consequence remains unclear. Elucidating the role is crucial to assess the rationale for using anti-inflammatory therapies in FTLD. Additionally, the process of glymphatic brain clearance has gained attention as a potential contributor in the disease pathophysiology.

In this multimodal biomarker study, we use a combination of ultra-high field (7T) MR, blood and cerebrospinal fluid (CSF) biomarkers to investigate the role of neuroinflammation, iron accumulation and brain clearance in FTLD, and to identify biomarkers to differentiate FTLD-TDP from FTLD-tau. We aim to include 25 patients with probable FTLD-tau, 25 with probable FTLD-TDP and 50 healthy individuals with 50% risk to develop FTLD. We will use several MRI techniques, including magnetic resonance spectroscopy, diffusion weighted spectroscopy and quantitative susceptibility mapping. In addition, we will assess the prevalence of perivascular spaces (PVS) and the mobility of CSF to address glymphatic brain clearance. We will compare quantitative MR markers between patients with FTLD-tau and FTLD-TDP, presymptomatic mutation carriers and healthy controls, and correlate these measures with clinical data and biomarkers in blood and CSF.

We obtained ethical approval from the Medical Ethics Committee Leiden Den Haag Delft (NL78272.058.21). The results will be disseminated through presentations at national and international conferences, open-access peer-reviewed publications, ClinicalTrials.gov and to the public through social media posts and annual newsletters.

Prescribing antibiotics may reinforce patients’ beliefs that antibiotics are needed and increase future consultations for similar symptoms. This review determines the effect of antibiotic prescribing for respiratory infections in primary care on future reattendance.

A systematic review and meta-analysis of randomised controlled trials (RCTs) and cohort studies and reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Participants were adults or children presenting with respiratory infection in primary care.

MEDLINE (Ovid), PubMed, Embase, the Cochrane Central Register of Controlled Trials, clinical trial registries and grey literature sources were searched from inception until 6 February 2024.

Eligible studies included open-label RCTs or cohort studies of antibiotics compared with no antibiotics in adults or children with respiratory infections. The outcome of interest was reattendance at least 28 days after the initial consultation.

Two reviewers independently screened, selected, assessed the quality and extracted data. Separate meta-analyses were presented for RCT and cohort studies and a combined meta-analysis of all studies.

We identified 2128 records and reviewed 48 full texts, of which five met the inclusion criteria. These reported three RCTs (1207 randomised to antibiotics, 672 controls) and three cohort studies (209 138 exposed to antibiotics, 46 469 controls). In the meta-analysis of RCTs, relative risk (RR) of reattendance with antibiotics was 1.10 (95% CI: 0.99 to 1.23), and in cohort studies, RR was 1.21 (95% CI: 0.94 to 1.49). An important limitation is that most studies were in UK primary care.

Evidence suggests prescribing antibiotics for acute respiratory tract infections in primary care probably modestly increases future reattendance for similar conditions. Reducing antibiotic prescribing may help decrease demand for primary care.

It is unclear how mis- and disinformation regarding healthcare policy changes propagate throughout Latino communities via social media. This may lead to chilling effects that dissuade eligible individuals from enrolling in critical safety net programmes such as Medicaid. This study will examine pathways and mechanisms by which sentiment in response to mis- and disinformation regarding healthcare policies on social media differentially impact health disparity populations, thus supporting the design of tailored social media interventions to mitigate this.

We will search social media from X/Twitter, Facebook/Instagram and Reddit for keywords relating to health benefit programmes. Demographic, geographical location and other characteristics of users will be used to stratify social media data. Posts will be classified as fake-news-related or fact-related based on curated lists of fake-news-related websites. The number, temporal dissemination and positive or negative sentiment in reacting to posts and threads will be examined using the Python-based Valence Aware Dictionary and sEntiment Reasoner (VADER). Using a crowd-sourcing methodology, a novel Spanish-language VADER (S-VADER) will be created to rate sentiment to social media among Spanish-speaking Latinos. With the proposed approach, we will explore reactions to the dissemination of fake-news- or fact-related social media tweets and posts and their sources. Analyses of social media posts in response to healthcare-related policies will provide insights into fears faced by Latinos and Spanish speakers, as well as positive or negative perceptions relating to the policy over time among social media users.

Our study protocol was approved by the University of California, Los Angeles IRB (IRB#23–0 01 123). Results from this study will be disseminated in peer-reviewed journals and conference presentations, and S-VADER will be disseminated to public repositories such as GitHub.

Undergraduate students report a high level of trait anxiety, which is a risk factor for further psychological decline if unmanaged. Music-based interventions are cost-effective and have been found to improve indices of anxiety. More recently, music with auditory beat stimulation (ABS) has been shown to improve symptoms of anxiety to a greater extent than music alone. While there is limited empirical evidence, music interventions with ABS may also be effective at targeting neurophysiological markers of anxiety. The aim of this study is to evaluate the effectiveness of a novel music with ABS intervention on self-report and neurophysiological indices of anxiety in undergraduate students with trait anxiety. It is hypothesised that relative to a pink noise control, listening to music with ABS will lower self-reported anxiety, reduce salivary cortisol, increase heart rate variability, increase theta and alpha-band electroencephalography (EEG) power and decrease beta and gamma-band EEG power.

Fifty Canadian undergraduate students who self-report experiencing anxiety will be recruited for this two-arm randomised controlled trial. Participants will be randomised to a single music session with ABS or pink noise; each intervention ranges from 24 min to 27 min. Outcomes will be assessed at baseline and immediately following the intervention and will be self-reported anxiety and affect (the State-Trait Inventory of Cognitive and Somatic Anxiety and the Self-Assessment Manikin), salivary cortisol, heart rate variability measured by ECG and cortical measures of anxiety (measured by EEG). Repeated measures analyses of covariance will be performed to evaluate the effect of condition assignment on outcome measures.

This study will be conducted under the Declaration of Helsinki. This study was approved by the Toronto Metropolitan University Research Ethics Board (REB-2020-068) and registered on ClinicalTrials.gov (NCT05442086). The findings of this study will be published in a peer-reviewed journal.

The COVID-19 pandemic prompted a significant increase in the use of remote consultations—by telephone or video—in both primary and secondary healthcare. The reported advantages of remote consulting for both patients and clinicians include greater efficiency, flexibility and convenience. However, disadvantages, such as the uncertainty created by a loss of face-to-face contact, have also been highlighted. The aim of this study was to explore, explain and interpret patients’ and clinicians’ perceptions and experiences of remote consultations and assist decision-making about their future use.

A qualitative study based on semistructured online interviews.

Primary mental healthcare or secondary care cardiology services, London, UK, February–March 2022.

Primary care mental health patients (n=5), primary care clinicians (general practitioners) (n=15), secondary care cardiology patients (n=9) and secondary care cardiology clinicians (n=5).

The results demonstrate that a range of factors have influenced the experiences of both clinicians and patients and indicate shifts in the norms of professional practice and clinician–patient relationships.

Patients and clinicians demonstrated pragmatic acceptance of remote consultations and, looking forward, a preference for a balanced ‘hybrid model’ of remote and face-to-face appointments. The study also highlights a need to consolidate and build on the informal learning and adaptation to remote consulting that has already taken place.

The use of e-health interventions has grown in demand due to their accessibility, low implementation costs and their potential to improve the health and well-being of people across a large geographical area. Despite these potential benefits, little is known about the cost-effectiveness of self-guided e-health interventions. The aim of the study was to compare the cost and consequences of ‘iSupport’, an e-health intervention to reduce mental health issues in dementia carers.

A cost-consequence analysis (CCA) of a multi-centre, single-blind randomised controlled trial of iSupport. The CCA was conducted from a public sector (National Health Service, social care and local authority) perspective plus a wider societal perspective. Delivery costs of iSupport were collected using a bottom-up micro-costing approach.

352 participants were recruited from three centres in England, Wales and Scotland.

Participants eligible for inclusion were adults over the age of 18 years who self-identified as an unpaid carer with at least 6 months of experience caring for an individual with a diagnosis of dementia. Between 12 November 2021 and 31 March 2023, 2332 carers were invited to take part in the study. 352 participants were randomised: 175 randomised to the iSupport intervention group and 177 to the usual care control group. The mean age of participants in the intervention and control groups was 63 and 62, respectively.

The CCA presented the disaggregated costs and health-related quality of life measured using the EuroQol five-dimension.

There was no significant difference in generic health-related quality of life measured using the EQ-5D-5L (p=0.67). Both groups reported higher mean costs between baseline and 6 months, but the change in costs was significantly lower in the intervention group. Between baseline and 6 months, the mean change in total resource use costs from the public sector perspective was significantly different between groups (p=0.003, r=–0.161) reporting a mean change per participant of £146 (95% CI: –33 to 342) between the intervention and control groups. From the wider societal perspective, there was no significant difference (p=0.23) in the mean change in total resource use and informal care costs between the two groups from baseline to 6 months.

Use of iSupport was associated with reduced health and social care resource use costs for carers compared with care-as-usual. Self-guided e-health interventions for dementia carers may have the potential to reduce health and social care resource use and wider societal costs, but evidence relating to their effectiveness and cost-effectiveness is lacking.

The involvement of male partners in the care and treatment of HIV-positive pregnant women is essential for improving health outcomes and ensuring optimal adherence to antiretroviral therapy (ART). Although ART has been shown to be effective in preventing mother-to-child transmission of HIV, maintaining adherence to the prescribed triple ART regimen remains a significant challenge. However, there has been a lack of research on the role of male partners in supporting ART adherence during pregnancy.

To assess male partner involvement in triple ART drug adherence and associated factors among HIV-positive pregnant women in government hospitals of the North Gojjam Zone, Amhara Region, Northwest Ethiopia, 2023.

An institution-based cross-sectional study was conducted.

The study was carried out in hospitals located in the North Gojjam Zone of Northwest Ethiopia.

The study was conducted among 410 male partners of HIV-positive pregnant women from 1 April 2023 to 30 May 2023.

The primary outcome was to assess the involvement of male partners in triple ART adherence, while the secondary outcome was to identify factors associated with the involvement of male partners on triple ART adherence among HIV-positive pregnant women. The association between variables was assessed using bivariate and multivariable logistic regression models, and a p value

A total of 410 participants were included, with a response rate of 97.2%. The prevalence of male partner involvement in triple ART drug adherence among HIV-positive pregnant women was 21.2%. Multivariable logistic regression showed that educational status (AOR (Adjusted Odds Ratio)=2.5, 95% CI 1.26 to 4.96), place of residence (AOR=4.8, 95% CI 3.17 to 7.27), and the time taken to travel from home to the facility (AOR=3.1, 95% CI 1.51 to 6.36) were significantly associated with male partner involvement.

This study demonstrates that compared with a study conducted in Malawi, male partner involvement in triple ART drug adherence was lower. Male partner involvement in triple ART adherence among HIV-positive pregnant women was strongly associated with educational status, place of residence and the time taken to travel from home to the health facility. Empowering men to actively participate in healthcare decisions and treatment plans for their partners can foster a sense of responsibility and enhance commitment to adherence.

Weight loss is often recommended as the primary intervention for infertility in individuals with high body mass index. However, focusing on body mass index might overlook other important factors like cardiometabolic health. This study aims to examine cardiometabolic health in patients seeking fertility treatment and its impact on reproductive outcomes.

A cross-sectional analysis of 800 systematically selected participants (400 couples) will be completed on a single visit to the study site. This session will involve taking blood samples to examine metabolic biomarkers, the completion of questionnaires assessing preconception health factors and an exercise ‘step test’ to assess cardiorespiratory fitness. Metabolic panels will be compared with target values and, where available, normative population data. Fitness data will be transformed into normative percentile values based on the participant’s age and sex. Patients will be followed for 2 years to allow yearly data collection related to conception, gestation and parturition. Associations between cardiometabolic health during the preconception phase and reproductive outcomes will be examined.

The Newfoundland and Labrador Health Research Ethics Board has provided ethical approval for this study (HREB #20230825). Each patient will be required to give written consent prior to any data collection. We will share study findings at conferences and submit manuscripts to peer-reviewed journals. Additionally, we will create knowledge translation presentations for Newfoundland and Labrador Fertility Services and Family Practice Clinics.
