Students enrolling in higher education often adopt lifestyles linked to worse mental health, potentially contributing to the peak age onset of mental health problems in early adulthood. However, extensive research is limited by focusing on single lifestyle behaviours, including single time points, within limited cultural contexts, and focusing on a limited set of mental health symptoms.

The UNIversity students’ LIFEstyle behaviours and Mental health cohort (UNILIFE-M) is a prospective worldwide cohort study aiming to investigate the associations between students’ lifestyle behaviours and mental health symptoms during their college years. The UNILIFE-M will gather self-reported data through an online survey on mental health symptoms (ie, depression, anxiety, mania, sleep problems, substance abuse, inattention/hyperactivity and obsessive/compulsive thoughts/behaviours) and lifestyle behaviours (ie, diet, physical activity, substance use, stress management, social support, restorative sleep, environment and sedentary behaviour) over 3.5 years. Participants of 69 universities from 28 countries (300 per site) will be assessed at university admission in the 2023 and/or the 2024 academic year and followed up for 1, 2 and 3.5 years.

The study was first approved at a national level in Brazil (CAE:63025822.8.1001.5346). Study sites outside Brazil obtained additional ethics approval from their institutions using the main approval. Results from the UNILIFE-M cohort will be disseminated through scientific publications, presentations at scientific meetings, press releases, the general media and social media.

This scoping review aims to map evidence or literature on improvement strategies used by health leaders and professionals to strengthen the safety climate in the operating room.

A scoping review was performed on the basis of the method proposed by the Joanna Briggs Institute and applied to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) extension.

16 academic and grey literature data sources were searched using search terms on 17 January 2025, namely, Medical Literature Analysis and Retrieval System Online via Pubmed, Latin American and Caribbean Literature on Health Sciences via the Virtual Health Library, Cumulative Index to Nursing and Allied Health Literature, Scopus, Web of Science, Embase, PsycINFO, Cochrane Library, WorldCat, Digital Library of Theses and Dissertations, Brazilian Association of Surgical Center Nurses, Center for Material and Sterilization and Anesthetic Recovery, Association of Portuguese Operating Room Nurses, Association of PeriOperative Registered Nurses, Institute for Healthcare Improvement, WHO and Agency for Healthcare Research and Quality.

Study selection, data extraction and synthesis were based on the following eligibility criteria based on the acronym PCC (participants, concept, context): participants (health leaders and professionals), concept (strategies to improve the safety climate) and context (operating room). This scoping review considered studies published from 2009 onwards.

Information on the objective, method and findings addressing improvement strategies employed to strengthen the safety climate in the surgical centre was retrieved. The findings are presented in tables and in a qualitative thematic summary.

A total of 26 studies were analysed, published between 2009 and 2024, with the USA as the country of origin of the publications with the highest number (11 studies). As for the methodological approach, intervention and quasi-experimental studies stand out. When the studies in this review were mapped, strategies that strengthened the safety climate in the operating room were identified and grouped into two main axes that are interrelated: communication tools and training programmes.

It is evident that the implementation of tools that promote communication and training programmes enhances safe surgical care, as they contribute substantially to the domains of the safety culture. The use of communication protocols in the operating room is recommended as a perioperative safety tool.

This scoping review adhered to a protocol previously published in this journal and that is registered on the Open Science Framework website (https://osf.io/zg8nu/).

Values and preferences are key determinants of optimal care, and variability in patient values and preferences often dictates differences in patient management. Clinicians’ views of patients’ values and preferences may differ across cultural aspects and stage of training, but the extent to which this is the case remains uncertain. One key value and preference issue is the trade-off between quantity and quality of life, and this issue is particularly prominent among patients with dementia. We therefore propose to investigate the extent to which physicians’ perceptions of optimal management for patients living with advanced dementia may differ due to cross-cultural factors and stage of medical training.

We will conduct a sequential explanatory mixed-methods study (QUAN -> qual). First, we will administer paper-based or electronic surveys during educational sessions, conferences and rounds to medical students, residents and physicians in ten countries, either in person or online. Following that, a qualitative inquiry, guided by the findings of the quantitative study and the principles of the interpretive description design, will inform an in-depth exploration of the predictive factors identified in the quantitative data analysis.

The Hamilton Integrated Research Ethics Board at McMaster University has approved this study (approval number 2024-17651). We will disseminate our findings in peer-reviewed publications and present results at conferences as oral and poster presentations.

The analgesic and antipyretic paracetamol (acetaminophen) is generally considered safe in therapeutic doses. The most important toxic effect is hepatotoxicity after supratherapeutic doses or in the presence of risk factors (eg, malnutrition, alcoholism). According to the WHO analgesic ladder, a combination of a non-opioid analgesic such as paracetamol with a strong opioid is recommended as step III treatment of patients with chronic pain, despite limited evidence for this approach. The main aim of this study is to test the hypothesis that paracetamol does not provide clinically relevant benefits when added to strong opioids in patients with chronic pain.

Investigator-initiated, randomised, double-blind, placebo-controlled, non-inferiority trial at two Swiss hospitals. A total of 140 patients with chronic pain requiring strong opioids and paracetamol ≥1.5 g/day for at least 7 days will be enrolled and randomised to either continued combination treatment or strong opioid plus placebo. In the first study phase (days 1–7), patients receive identically looking capsules containing either paracetamol at the exact dose previously used or a placebo. During a second study phase (days 7–14), all patients stop the blinded study medication (paracetamol and placebo) with follow-up to day 14. Adherence will be assessed by pill count and measurement of paracetamol and opioid serum concentrations. Patients are instructed to use a pain diary daily during the whole study. The primary outcome is the average pain score on day 7 using a 10 cm visual analogue scale (VAS). A difference between groups of ≤8 mm will be considered clinically irrelevant. Secondary outcomes will include VAS pain score on day 14, number of opioid rescue doses used, subjective ratings of overall feeling of well-being, quality of life, nausea/vomiting, drowsiness and constipation, and other adverse events, and potential effects of study drug concentrations and opioid receptor and cytochrome P450 (CYP) genotypes on the observed differences.

The study was approved by the Ethics Committee (Ethikkommission Bern, reference number 2021-01518) and the Swiss Agency for Therapeutic Products (Swissmedic, reference number 701286). Results will be published in open-access policy peer-reviewed journals. The study is funded by the Swiss National Science Foundation (grant number 32 003B_201072).

NCT05088876.

This study aimed to describe the epidemiology, outcomes and costs of four immune-mediated inflammatory rheumatic diseases (IMIRDs)—systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS)—in Brazil’s public and private healthcare systems from 2018 to 2022.

Retrospective observational study.

The study was conducted across hospital and outpatient levels of care in Brazil, based on nationwide data representing the public (Department of Informatics of the Unified Health System—DATASUS) and private (National Supplementary Health Agency—ANS) healthcare sectors.

The study analysed data from four distinct systems: 609 427 patients from the public Outpatient Information System (SIA), 32 119 patients from the public Hospital Information System (SIH), 19 083 deaths from the public Mortality Information System (SIM) and 11 846 hospitalisations from the private healthcare system (ANS).

RA had the highest incidence, ranging from 19.9 to 24.9 per 100 000, while SLE remained stable (6.3–6.7 per 100 000). Prevalence increased for all diseases: RA rose from 95.7 to 136.8, SLE from 23.4 to 38.9, AS from 15.0 to 23.6 and PsA from 10.8 to 17.4 per 100 000. SLE had the highest hospitalisation (7.2%) and lethality rates (8.7%), along with the highest average outpatient cost (US$440.9 per patient). In the private system, RA and SLE accounted for the most hospitalisations (36.3% each). SLE had the highest proportion of emergency hospitalisations (70.5%), while PsA had the highest proportion of elective hospitalisations (61.8%).

RA had the highest prevalence and incidence rates among the studied IMIRDs, while SLE was associated with the highest lethality, outpatient costs and emergency hospitalisations. The rising prevalence of these diseases highlights their growing burden on Brazil’s healthcare systems.

NCT06698900.

Understanding contextual drivers of family planning is crucial for designing effective, context-specific policies and programmes. This study aimed to assess (1) the extent to which province-level contextual factors are associated with both coverage and wealth-related inequalities in demand for family planning satisfied by modern methods (mDFPS) across provinces in low- and middle-income countries (LMICs), and (2) whether these factors influence mDFPS at women’s level.

Observational study using multilevel modelling at both ecological and individual levels.

We analysed data from Demographic and Health Surveys between 2011 and 2022 in 46 LMICs.

Ecological analysis included 621 provinces. Individual-level analysis included 302 493 women aged 15–49 years, currently married or in union, and in need of contraception (unweighted).

Demand for family planning satisfied by modern methods (mDFPS) and wealth-related inequalities in mDFPS, assessed using the slope index of inequality (SII) and the concentration index (CIX).

In both income groups, at the province level, higher mean women’s schooling and greater proportion of employed women were positively associated with mDFPS coverage. In contrast, higher male-to-female educational attainment ratios were inversely associated with mDFPS. Provinces with higher means of women’s schooling also showed lower wealth-related inequalities in mDFPS. At the individual level, women residing in provinces with higher male-to-female educational attainment ratios were found to have lower odds of mDFPS, regardless of the income group. Additionally, the factors influencing individual women’s mDFPS varied depending on the income level of the country’s provinces.

Women’s empowerment and gender equality in education at the province level significantly influence family planning outcomes. Targeted interventions that address each region’s specific educational, economic and demographic contexts are crucial for improving coverage and reducing disparities in family planning services.

This study aims to assess the burden and predictors of age-related macular degeneration (AMD) among older age patients with diabetes attending comprehensive specialised hospitals in Northwest Ethiopia.

A multicentre cross-sectional study was conducted among older patients with diabetes using a systematic random sampling technique.

The study was conducted at five comprehensive specialised hospitals in Northwest Ethiopia from 8 May to 8 June 2023.

The study included 832 diabetic individuals aged 40 years and above.

Data were collected using a pretested structured questionnaire and physical examinations.

In this study, a total of 832 participants were involved, with a response rate of 96.85%. The burden of AMD was 15.4% (95% CI 13.0% to 18.0%). Male sex (adjusted OR (AOR) 2.04, 95% CI 1.17 to 3.56), older age (AOR 6.91, 95% CI 3.17 to 15.08), diabetes duration of 10 and more years (AOR 3.00, 95% CI 1.91 to 4.69), higher body mass index (AOR 2.56, 95% CI 1.15 to 5.71), presence of hypertension (AOR 2.45, 95% CI 1.56 to 3.85) and family history of diabetes mellitus (DM) (AOR 2.29, 95% CI 1.40 to 3.76) were positively associated with AMD.

This study found that the prevalence of AMD among patients with diabetes was 15.4%. Older age, male sex, longer DM duration, higher body mass index, presence of hypertension and family history of DM were significantly associated with AMD. Targeted screening of at-risk individuals for AMD, public health awareness campaigns focusing on these factors and further research to understand the burden and underlying mechanisms of these associations with AMD are recommended.

To describe the lessons learnt during the promotion of a new approach to the care of critically ill patients in TanzaniaEssential Emergency and Critical Care (EECC).

A descriptive qualitative study using thematic analysis of structured interviews.

The study was conducted in Tanzania, involving 11 policymakers, researchers and senior clinicians who participated in the promotion of EECC in the country.

Five inter-related themes emerged from the promotion of EECC in Tanzania: (1) early and close collaboration with the government and stakeholders; (2) conduct research and use evidence; (3) prioritise advocacy and address misconceptions about EECC; (4) leverage events and embed activities in other health system interventions; and (5) employ a multifaceted implementation strategy. The themes map to the normalisation process theory domains of coherence, cognitive participation, collective action and reflexive monitoring.

The integration of EECC into Tanzania’s health policy is a result of a multidisciplinary collaboration including government and partners that has used evidence, advocacy and context and included multifaceted implementation strategies. The lessons from Tanzania’s experience provide guidance for adoption in similar settings to improve critical care systems, foster access to care and optimal outcomes for all critically ill patients.

To investigate the occurrence of depression and mental health disorders other than depression among Brazilian people with intellectual disabilities, analysing data from a national household survey.

Cross-sectional epidemiological study using data from the 2019 National Health Survey (PNS).

Brazil, nationwide data collection in urban and rural private households.

272 499 individuals, among whom 1.2% (n=3198) reported intellectual disabilities.

Self-reported depression and mental health disorders other than depression (anxiety, panic, schizophrenia, bipolar disorder, psychosis or obsessive–compulsive disorder (OCD)), either isolated or comorbid.

Among people with intellectual disabilities, 43.2% reported at least one mental health disorder versus 13.7% without disabilities. In adults aged 0–59 years, intellectual disability was associated with higher odds of depression (adjusted OR (aOR) 3.25, 95% CI 1.76 to 6.00), mental health disorders other than depression (aOR 12.23, 95% CI 7.52 to 19.90) and depression associated with other mental health disorders (aOR 14.34, 95% CI 7.92 to 25.96). In older adults (≥60 years), risks also remained elevated: depression (aOR 1.71, 95% CI 1.04 to 2.79), mental health disorders other than depression (aOR 4.33, 95% CI 2.09 to 8.94) and depression associated with other mental health disorders (aOR 2.98, 95% CI 1.49 to 5.95). Women with intellectual disabilities were more likely to report depression and multimorbidity, while men more often reported non-depressive disorders. Poorer self-perceived health was consistently linked to worse outcomes across age groups.

Mental health disorders and their comorbidities are significantly more prevalent among people with intellectual disabilities in Brazil. These findings highlight the urgent need for inclusive, equitable and specialised mental healthcare policies.

Effective postoperative pain management is a critical component of surgical care, directly influencing patient recovery, satisfaction and long-term outcomes. Despite recent advances in pain management, postoperative pain remains poorly managed worldwide, suggesting that postoperative pain outcomes are influenced by factors beyond the inherent efficacy of available treatments. This scoping review aims to map the factors influencing postoperative pain management and recommendations that support optimal, evidence-based pain management after surgery.

A mixed methods scoping review will be conducted in accordance with the Joanna Briggs Institute manual for evidence synthesis and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping review guidelines. PubMed (MEDLINE), Cumulative Index to Nursing & Allied Health Literature and PsycINFO will be searched for the relevant literature from the journals’ inception to September 2025. Two reviewers will independently conduct the screening of titles and abstracts, full-text articles and data extraction. Data will be mapped onto the Theoretical Domains Framework and Capability, Opportunity, Motivation—Behavior model. Where additional data requires coding, thematic analysis will be conducted using NVivo data management software.

The scoping review will analyse publicly available data. Therefore, ethical approval is not required. The findings will serve as a foundation for engaging relevant stakeholders in discussions aimed at implementing systemic changes to support healthcare providers in enhancing postoperative pain management. The results will be disseminated through a peer-reviewed journal publication, local fora and conference presentations to ensure broad visibility and impact.

Osteoarthritis (OA) is a degenerative and progressive joint condition causing pain and disability. Physical exercise is recognised as the most effective intervention since individuals with this condition often experience muscle weakness, balance deficits and chronic pain. Additionally, knee osteoarthritis (KOA) is associated with central sensitisation, contributing to chronic pain conditions. Transcranial Direct Current Stimulation (tDCS), a non-invasive neuromodulation technique, has been employed to induce changes in pain perception by altering cortical excitability, potentially reducing chronic pain.

This is a protocol for a randomised controlled trial. Participants will be allocated to two groups: G1 (active tDCS combined with exercise) and G2 (sham tDCS combined with exercise). The intervention protocol will last for 5 weeks, with two sessions per week on non-consecutive days. Pain intensity will be assessed as the primary outcome using the Numeric Rating Scale (NRS). The sample size was calculated based on a minimum clinically important difference of 3 points on the NRS between groups, with a statistical power of 80% and a significance level of 5%. Secondary outcomes will include physical function and global perceived change.

This protocol was approved by the Research Ethics Committee of the Trairi School of Health Sciences, Federal University of Rio Grande do Norte (Approval Number: 6.801.827), and it is in accordance with the Declaration of Helsinki for human research. Results will be published in peer-reviewed journals and presented at scientific events. This trial is registered in the Brazilian Clinical Trials Registry.

Stroke is the second leading cause of death worldwide, with the greatest burden in low- and middle-income countries (LMICs). Haemorrhagic stroke or spontaneous intracranial haemorrhage (sICH), including intraparenchymal haemorrhage (IPH) and subarachnoid haemorrhage (SAH), has the highest mortality and morbidity. Local management practices for haemorrhagic stroke vary greatly between geographical regions. The Planetary Outcomes after Intracranial Haemorrhage study aims to provide a global snapshot of the patient characteristics, processes of care and short-term outcomes of patients being treated for sICH across high- and low-income settings. It will also describe variation seen in care processes and available resources and time delays to receiving care. A greater understanding of the current state of sICH care is essential to identify possible interventions and targets for improved standards of care in all settings.

We describe a planned prospective, multicentre, international observational cohort study of patients admitted to hospital for management of sICH. We will include patients of all ages presenting to hospital with imaging evidence of sICH (IPH, intraventricular haemorrhage and/or SAH). The study will collect patient, care process and short-term outcome data, following patients for up to 30 days (or until discharge or death, whichever occurs first). Any centre globally where patients with sICH are admitted and managed can participate, targeting a sample size of 712 patients. The study will recruit centres worldwide through pre-existing research networks and by dissemination through neurosurgical and stroke conferences and courses. Each participating centre will complete a site questionnaire alongside patient data collection.

The study has received ethical approval by the University of Cambridge (PRE.2024.070). Participating centres will also confirm that they have undergone all necessary local governance procedures prior to starting local data collection. The findings will be disseminated via open access peer-reviewed journals, relevant conferences and other professional networks and lay channels, including the study website (https://plotich.org/) and social media channels (@plotichstudy).

Cardiovascular (CV) disease is the leading cause of morbidity and mortality globally. Low-density lipoprotein cholesterol (LDL-C) is an important modifiable risk factor of major adverse cardiovascular events. Patients without prior myocardial infarction (MI) or stroke but with established risk factors and elevated LDL-C may benefit from intensive lipid-lowering therapy (LLT); however, the size and potential healthcare burden of this population globally are not known. The benefits of evolocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, in these patients, are currently being studied in the phase 3 Effect of Evolocumab in Patients at High Cardiovascular Risk Without Prior Myocardial Infarction or Stroke (VESALIUS-CV) trial. To characterise the high-risk pre–CV-event (VESALIUS-CV–like) individuals in the real world, an observational study is being conducted across multiple countries.

This retrospective cohort study will use a common protocol and an analytical common data model approach to characterise VESALIUS-CV–like individuals in the real world across different geographical regions and healthcare settings. The study period will be from 2010 to 2022, subject to data availability in study sites. Patients aged 50 years and older at high risk of CV disease but without prior MI or stroke will be included in this study. VESALIUS-CV–like individuals are defined through a combination of the following: (1) one diagnosis of coronary artery disease, cerebrovascular disease, peripheral artery disease or diabetes with microvascular complications or chronic insulin use; (2) an elevated LDL-C measurement and (3) other high-risk factors. The objectives of this study are to estimate the prevalence of VESALIUS-CV–like individuals, describe their characteristics and care pathways and estimate their incidence rates of CV events and healthcare costs. The prevalence of VESALIUS-CV–like individuals will be expressed as annual prevalence; patient characteristics at index date will be presented using summary statistics; care pathways will be summarised as LLT prescription across time; and the incidence of defined CV events will be expressed as events per person-years as well as at certain time periods. Healthcare costs will be presented as CV-related costs in different time periods.

Approvals of the study protocol were obtained from relevant local ethics and regulatory frameworks for each participating database. The results of the study will be submitted to peer-reviewed scientific publications and presented at scientific conferences.
