Although low-density lipoprotein cholesterol (LDL-C) is established as the primary cardiovascular disease (CVD) risk factor, some individuals with LDL-C within desirable limits still develop coronary artery disease (CAD). Lipoprotein(a) (Lp(a)) has emerged as a genetically determined independent risk factor for CVD. This study aims to investigate Lp(a) by determining its association with coronary artery stenosis severity, identifying its ethnic-specific genetic determinants and assessing its relationship with an energy-dense dietary pattern.

The PUTRA-CV study is a 3-year, multicentre, case-control observational study involving adult patients who have undergone coronary angiography. The primary outcome is the association between Lp(a) levels and the severity of angiographic CAD (assessed by Gensini or Syntax score). Secondary outcomes include the frequencies of Lp(a)-associated single nucleotide polymorphisms (SNPs) (rs10455872 and rs3798220) and the association between dietary patterns and Lp(a) levels. Lp(a) will be measured using a particle-enhanced immunoturbidimetric method, and SNPs will be genotyped using high-resolution melting. Dietary intake will be assessed using a validated semiquantitative food frequency questionnaire. Data will be analysed using SPSS. Descriptive statistics will be used to summarise population characteristics. Bivariate analyses will use chi-square (2), independent t-tests or Mann-Whitney U tests as appropriate. The independent association between Lp(a) and coronary artery stenosis severity will be determined using multivariable logistic regression, adjusting for confounders. Empirically driven dietary patterns will be derived using reduced rank regression, and their association with Lp(a) will be assessed. For genetic analysis, allele frequencies of the LPA SNPs rs10455872 and rs3798220 will be calculated and compared between cases and controls.

To explore the challenges experienced by people with intellectual disability, their carers and health and social care professionals when using and managing medication.

A synthesis of qualitative research using meta-ethnography.

We searched seven databases: MEDLINE, Embase, CINAHL, Science, Social Science and Conference Proceedings Citation Indices (Web of Science), Cochrane Library, PsycINFO and Proquest Dissertations and Theses from inception to September 2022 (updated in July 2023).

We included studies exploring the challenges and perceptions of people with intellectual disability, their carers and health and social care professionals regarding medication management and use.

We reviewed 7593 abstracts and 475 full texts, resulting in 45 included papers. Four major themes were identified: (1) Medication-related issues, (2) navigating autonomy and relationships, (3) knowledge and training needs and (4) inequalities in the healthcare system. We formulated a conceptual framework centred around people with intellectual disability and described the interconnectedness between them, their carers and health and social care professionals in the process of managing and using medication. We identified challenges that could be associated with the person, the medication and/or the context, along with a lack of understanding of these challenges and a lack of capability or resources to tackle them. We developed an overarching concept of ‘collective collaboration’ as a potential solution to prevent or mitigate problems related to medication use in people with intellectual disability.

The effective management of medication for people with intellectual disability requires a collaborative and holistic approach. By fostering person-centred care and shared decision-making, providing educational and practical support, and nurturing strong relationships between all partners involved to form a collective collaboration surrounding people with intellectual disability, improved medication adherence and optimised therapeutic outcomes can be achieved.

The aim was to assess point-in-time stock availability and pricing of drugs used for postpartum haemorrhage management (oxytocin, misoprostol, heat-stable carbetocin and tranexamic acid (TXA)).

Cross-sectional point-in-time survey using an adapted version of the WHO/Health Action International methodology.

In public, for-profit and not-for-profit private health facilities and in pharmacies in the Democratic Republic of the Congo (DRC), India and Kenya.

211 health facilities in the DRC (n=63), India (n=76) and Kenya (n=72).

Availability was calculated as a mean percentage of facility types where each medicine was observed on the day of data collection. Average procurement prices were calculated by obtaining the current purchase price per drug at each facility and then averaging prices across all facility types.

Availability of the four medicines was limited, and only oxytocin in the DRC met the WHO’s benchmark of 80%. Across all countries, availability of oxytocin, misoprostol and TXA was lower in public health facilities than in other facility types, indicating an important gap. Where the four medicines were available, non-quality-assured products were predominant across the three countries. The average facility procurement prices in India and Kenya were reported to be lower than those in the DRC.

Availability of oxytocin, misoprostol, heat-stable carbetocin and TXA was suboptimal and varied by facility type and geography, and similar trends were found across the four drugs. This indicates that access strategies should be tailored to each drug, geographical area and facility type. Strategies to improve commodity access in public-sector facilities will be especially important, as well as improving the availability of quality-assured products, possibly through value-based procurement practices.

Despite global efforts, gender disparities in oncology may persist. Understanding these disparities within the context of major conferences can inform strategies to promote gender inclusiveness in the field. This study evaluates the participation of women and men at the American Society of Clinical Oncology (ASCO) 2024 congress, focusing on chairs, speakers and audience questioners.

Observational study.

152 recorded sessions of the ASCO 2024 annual meeting, one of the largest conferences in the field of oncology, available on the ASCO website.

Individuals serving as chairs, speakers and audience members who asked questions.

In this observational study, gender for chairs, speakers and audience questioners across 152 sessions of the ASCO 2024 congress was assessed by two independent reviewers using audio and video recordings. Speaking times for questions and responses were also evaluated. Statistical analyses, including ² and unpaired t-tests, were conducted to analyse the data.

Women were well represented as chairs (n=124) and speakers (n=402) in 66% and 95% of sessions, respectively. However, only 21% of questions from the audience were posed by women, while 37% of questions were asked by men and 42% online or by chairs/speakers. Women were more likely to pose questions when the sessions were chaired by women (71% vs 53%; p=0.047). There were no statistically significant gender disparities concerning speaking time (questions: p=0.30; responses: 0.53). The response dynamics indicated a pattern of gender homogeneity, with individuals more frequently responding to questions from their own gender.

While the balanced representation of women in leadership roles at the ASCO 2024 congress reflects positive development in gender equality, disparities in active participation persist. These findings underscore the need for strategies that not only promote women in visible roles but also foster an environment that supports their active engagement in scientific discussions.

Intracranial atherosclerosis is the main cause of stroke globally, with acute large vessel occlusive (LVO) stroke being a predominant contributor to stroke-related mortality. In recent years, aspiration thrombectomy (AT) has emerged as a novel therapeutic method for treating acute LVO stroke. The purpose of this study aims to investigate the safety and efficacy of AT alone or combined with stent retriever thrombectomy (SRT) in the treatment of acute LVO stroke

This is a multicentre and observational real-world study involving patients diagnosed with acute LVO stroke. Participants will be treated with AT alone or combined with SRT. According to the actual annual number of embolectomy in the sub-centre and the research years, the sample size of this study is estimated to be 400 patients, of which 300 patients of anterior circulation lesions and 100 patients of posterior circulation lesions are planned to be recruited, being considered that the incidence of posterior circulation is about 20–25%. Clinical data, including baseline characteristics, intraoperative details, postoperative outcomes and follow-up results, will be systematically collected using an Electronic Data Capture system over a follow-up period of 3 months. The primary efficacy endpoint is the rate of excellent functional outcome (modified Rankin Scale score range 0–3) after 90 days, and the successful recanalisation confirmed by digital subtraction angiography. The primary safety outcome is symptomatic intracranial haemorrhage within 48 hours (National Institutes of Health Stroke Scale score increase ≥4). This study will provide us with powerful guidance for the treatment of acute LVO stroke with different aetiologies.

This study protocol was approved by the Ethics Committee on Human Experimentation at Shandong Provincial Hospital Affiliated to Shandong First Medical University (approval number: SWYX:2022–1025). All the participating sites have received the ethics approval. The outcomes will be disseminated through national and international presentations and peer-reviewed publications.

Video games have been linked to a range of positive and negative effects on the mental health of adolescents and young adults. However, to better understand how games affect the mental health of young people, their use and experiences must be situated in the sociocultural and personal life contexts of individuals. Drawing from a cultural-ecosocial approach, this study combines cross-sectional and digital phenotyping measures to examine the effects of video games on the mental health of youth.

Participants will be young people aged 16–25 years from the community and living in the province of Quebec, Canada. An initial sample of 1000 youth will complete a cross-sectional survey online, including measures of socio-demographic context, gaming practices and experiences, streaming practices and experiences, as well as personality and well-being. Qualitative questions will explore personal views on games and mental health. A subsample of 100 participants will be selected for digital phenotyping, including daily surveys of well-being, gaming, streaming and social experiences, combined with passive mobile sensing (eg, geolocation). Analyses will include regression and mixed models for quantitative data, reflexive thematic analysis for qualitative data, and an integration of quantitative and qualitative results using participatory methods.

The study received ethical approval from the Institutional Review Board of McGill University (24-02-015). The dissemination of results will be conducted in partnership with a multi-stakeholder advisory committee, including youth who play video games, and will involve peer-reviewed publications, presentations to policymakers in Quebec, and workshops for clinicians and researchers.

Persistent pain after finishing breast cancer treatment is a common and disabling problem. The current state-of-the-art pain management advocates, in addition to biomedical (non-)pharmacological approaches, a biopsychosocial rehabilitation approach to address persistent pain, combining pain science education with promoting an active lifestyle through self-regulation techniques. We propose testing an innovative eHealth self-management support programme for this purpose in the breast cancer population with persistent pain after finishing cancer treatment. This delivery mode is believed to reduce barriers to pain self-management by providing timely, safe and cost-effective assistance addressing the biopsychosocial needs of patients. Utilising a chatbot format, the eHealth programme delivers pain science education and promotes physical activity (PA), personalised through decision-tree-based algorithms to support pain self-management. The programme aims to empower patients with understanding, coping skills and self-management techniques to reduce pain-related disability and enhance participation in daily life. The primary objective is to determine programme effectiveness compared with (1) usual care (superiority) and (2) a similar face-to-face pain self-management support programme (non-inferiority).

A pragmatic, three-arm randomised controlled trial was started in April 2024 at the University Hospitals of Antwerp and Leuven and primary care settings in Belgium. Participants are breast cancer survivors with persistent pain after finishing cancer treatment. Two hundred seventy participants will be randomised to one of three trial arms: (1) eHealth self-management support programme, (2) usual care or (3) a face-to-face self-management support programme. The ‘eHealth self-management support programme’ begins with a pain science education (PSE) module to initially convey key pain-related concepts and provide personalised pain management tips. Then, the programme progresses to daily activity planning to promote an active lifestyle. Guided by the Health Action Process Approach (HAPA) model, participants set and review daily activity goals and track progress. The eHealth self-management programme uses a chatbot and is accessible on any digital device. The ‘usual care programme’ involves sending the participants a study-specific brochure by postal mail and does not include any formal PSE and/or PA programmes. They may pursue or continue self-initiated care. In Belgium, usual care primarily involves pharmacological treatment, general advice on PA and the provision of informational brochures. The ‘face-to-face self-management support programme’ mirrors the eHealth intervention, combining PSE with PA coaching. It starts with three individual sessions with a trained physical therapist for biopsychosocial assessment and PSE, followed by six sessions on goal setting and active lifestyle coaching. The educational content is delivered both verbally and in written form. The primary outcome will be pain-related disability 6 months after baseline assessment. As a key secondary outcome, the effect on pain beliefs and attitudes will be investigated after the educational part of the eHealth and face-to-face programme (ie, at 6 weeks after baseline). Other secondary outcomes related to other dimensions of pain and physical-, psychosocial- and health-economic outcomes will be assessed at 12 weeks and 6 and 12 months after baseline as well.

The study will be conducted in accordance with the Declaration of Helsinki (2024). The protocol has been approved by the ethical committee of the University Hospitals of Leuven and Antwerp. Results will be disseminated via peer-reviewed scientific journals and presentations at congresses. Ethical Committee of the University Hospitals Leuven and Antwerp: BUN B3002023000132.

Postoperative pulmonary complications (PPCs) represent a significant cause of postoperative morbidity and even mortality. However, there is a lack of consensus regarding this composite endpoint, the definition of the individual components, classification and optimal outcome measures. This study aims to refine the PPCs composite framework by evaluating its construct validity, assessing the necessity and risks of a composite measure and exploring the feasibility of differentiating severity categories.

A Delphi consensus process will be conducted, engaging an international multidisciplinary group of 30–40 panellists, including clinicians, researchers, patients, public representatives and health economists. Through iterative rounds, the study will seek agreement on the individual components of the PPCs composite. Additionally, consensus will establish a framework for a composite outcome measure based on a standardised severity classification, appropriate timeframes and weighted grading of PPCs.

Consensus, defined by ≥75% concurrence in multiple choice questions or on Likert–scale statements, will be evaluated from round 2 onwards. Delphi rounds will be continued until all statements have reached stability of responses evaluated by ² tests or the Kruskal-Wallis test.

The study will be conducted in strict compliance with the principles of the Declaration of Helsinki and will adhere to ACCORD guidance for reporting. Ethics approval has been obtained for this study from the University of Wolverhampton, UK (SOABE/202425/staff/3). Informed consent will be obtained from all panellists before the commencement of the Delphi process. The results of the study will be published in a peer–reviewed journal with the authorship assigned in accordance with ICMJE requirements.

An increasing number of randomised controlled trials (RCTs) have compared the analgesic effects of erector spinae plane block with those of intercostal nerve block for postoperative analgesia in various surgeries, but the results have been inconsistent. This protocol of a systematic review and meta-analysis aims to evaluate whether the analgesic effects of erector spinae plane block are superior to those of intercostal nerve block.

A comprehensive search will be conducted by two authors via PubMed, EMBASE, the Cochrane Library and Web of Science from inception to 25 December 2025. No search language restrictions will be set. We will include RCTs that compared the analgesic effects of erector spinae plane block with those of intercostal nerve block after surgery. Total opioid consumption over 24 hours postoperatively will be the primary outcome. The duration of analgesia, pain intensity and incidence of adverse effects will be the secondary outcomes. RevMan V.5.4 software will be used to conduct the statistical analysis. The Cochrane Collaboration’s tool will be used to assess the risk of bias. The I² test will be used to assess heterogeneity. Subgroup analysis and meta-regression will be performed to explore the source of heterogeneity. Sensitivity analysis will be used to examine the reliability of the pooled data. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to recommend evidence quality. Publication bias will be evaluated via Egger’s test.

Ethical approval is not applicable. The results will be publicly published on completion.

Thyroid-associated ophthalmopathy (TAO), the most common orbital disease in adults, is an autoimmune disease of the orbital and periorbital tissues. Typical ocular symptoms of TAO include periorbital oedema, conjunctival congestion and oedema, eyelid retraction, exophthalmos, restrictive strabismus, etc. Hypercholesterolaemia is considered one of the modifiable risk factors of TAO. However, it is unclear whether lipid levels are related to TAO activity and severity and the intravenous glucocorticoids (GC) therapeutic effect. The study aims to evaluate the association between initial lipid and lipoprotein levels, the clinical features of TAO and the efficacy of intravenous methylprednisolone in patients with moderate-to-severe TAO, as well as to explore the oxidative stress-related mechanisms involved.

This real-world prospective cohort study will recruit 178 patients with moderate-to-severe TAO who receive two intravenous methylprednisolone regimens, respectively. The primary outcome is the improvement in the composite index at 3 months after baseline treatment, with secondary outcomes including other ocular features, changes in serological characteristics and major adverse events.

The study protocol was approved by the ethics committees of Xiangya Third Hospital of Central South University (Kuai241012) on 29 November 2024. The study will be conducted according to the guidelines of the Declaration of Helsinki. Participants will be informed of the purpose and content of the study and will complete a written informed consent form before being recruited. The findings will be published in peer-reviewed journals as well as in reports of relevant conferences.

To determine whether postponing daily medical rounds to provide additional preparation time for residents reduces round duration and alters time allocation during rounds, with the hypothesis that increased preparation leads to more efficient rounds without reducing patient contact.

Time and motion study with a before-and-after comparison.

Internal medicine division of Lausanne University Hospital, a Swiss tertiary teaching hospital.

75 residents; 60% women; mean age of 29.6 years and 3.0 years of training.

In 2017, the daily work schedule was reorganised by postponing rounds from 09:00 to 10:00 and moving educational sessions to the afternoon, thereby freeing 90 min to prepare patient cases before rounds.

The primary outcome was the duration of rounds and the proportion thereof spent with patients, using computer systems or in discussion with colleagues. Secondary outcomes included the detailed distribution of resident activities during the officially scheduled round period, particularly time dedicated to supervision, teaching and administrative tasks.

Round duration decreased from 142 min per shift (95% CI 128 to 156) in 2015 to 112 min (95% CI 101 to 124) in 2018 (p=0.001). The proportion of round time spent directly with patients remained stable at 47%. Computer use during rounds decreased from 43% to 32% (p

Postponing rounds to allow more preparation time was associated with shorter, possibly more efficient rounds, reduced computer use in patient presence and increased supervision and teaching.
