Chronic respiratory diseases (CRDs), such as asthma and chronic obstructive pulmonary disease (COPD), are among the leading non-communicable diseases (NCDs) worldwide. However, diagnosing CRDs in low-income and middle-income countries (LMICs) remains challenging due to limited access to spirometry and trained professionals. Aggravating the burden, CRDs often coexist with other NCDs, increasing healthcare costs, reducing quality of life and elevating mortality. These challenges highlight the need for simple case-finding approaches for CRDs, such as the COPD in Low-Income and Middle-Income Countries Assessment (COLA-6) questionnaire, to support prompt identification and appropriate care within NCD services in LMICs.
To evaluate the discriminative accuracy, feasibility and implementation of the COLA-6 questionnaire in identifying and managing CRDs in Brazilian Primary Healthcare (PHC) services for NCDs.
The Multimorbidity Approach for REspiratory Solutions (MARES) study consists of three work packages to be conducted in PHC services in São Carlos/SP and São Paulo/SP, Brazil.
MARES-1: A cross-sectional observational study enrolling 859 individuals with at least one NCD receiving care in PHC. The COLA-6 questionnaire will be administered by the research team and compared with quality-assured spirometry. The Chronic Airways Assessment Test (CAAT), Asthma Control Questionnaire (ACQ-7) and fractional exhaled nitric oxide (FeNO) will also be assessed. The diagnostic performance of COLA-6 for identifying CRDs—including COPD, asthma, preserved ratio impaired spirometry, restriction and overlaps—will be assessed using area under receiver operating characteristic curves and 95% CIs.
MARES-2: A cross-sectional observational study enrolling 20 healthcare professionals (physicians, physiotherapists, community health agents and nurses) from five PHC services. These professionals will apply the COLA-6 during routine NCD care to a total sample of 1000 patients. Qualitative interviews will be conducted to explore barriers and facilitators to the implementation of COLA-6, using deductive thematic analysis.
MARES-3: A longitudinal, prospective observational study in which patients from MARES-1 and MARES-2 will be reassessed at 6-month follow-up. A total sample of 473 participants with abnormal spirometry, a diagnosis of CRD or high risk for CRDs is expected. Participants will undergo spirometry, and a subset will be interviewed to explore their healthcare experiences through qualitative thematic analysis. Access to diagnostic and treatment services in Brazil will be assessed. Changes in spirometry values, FeNO, CAAT and ACQ-7 scores from baseline to 6 months in patients from MARES-1 will be analysed.
This study has been approved by the Ethics Committees of Federal University of São Carlos and University of Santo Amaro (UNISA). Ethical approval was also granted by the University College London. Results will be disseminated through peer-reviewed medical journals and presentations at international conferences. Results will improve identification of CRDs, addressing a significant gap in current PHC settings.
Each year, millions of people experience recurrent diverticulitis episodes. Elective sigmoid colon resection reduces the risk of recurrence, but The American Society of Colon and Rectal Surgeons recommends individualising surgical decisions based on the impact of the condition on a patient’s quality of life (QoL). However, no threshold for QoL impairment has been established to guide decision-making, and evidence comparing elective colectomy with medical management in terms of QoL limitation is limited. To address these gaps and to guide treatment decision-making, we designed the Comparison of Surgery and Medicine on the Impact of Diverticulitis (COSMID) trial.
The COSMID trial is a large, pragmatic randomised trial including patients with QoL-limiting diverticulitis that aims to determine if partial colectomy is superior to medical management and explore subgroups that are more likely to respond to each treatment.
COSMID will recruit 250 English-speaking and Spanish-speaking adults with imaging-confirmed and QoL-limiting diverticulitis (defined using a modified diverticulitis-related QoL survey). Participants are randomly assigned to undergo elective partial colectomy or receive comprehensive medical management (eg, selected from options including fibre, probiotics, mesalamine and rifaximin). A total of 100 patients who decline randomisation but consent to follow-up will be included in a parallel observational cohort. The primary outcome is the time-averaged score of the Gastrointestinal Quality of Life Index at 6, 9 and 12 months after randomisation. Secondary outcomes include clinical adverse events, healthcare utilisation, recurrent episodes of diverticulitis and additional patient-reported outcomes like the Diverticulitis Quality of Life instrument, decisional regret and work productivity. Exploratory analyses aim to identify differential treatment effects based on patients’ characteristics.

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/).
Insomnia is a common complaint among patients with opioid use disorder (OUD) maintained on buprenorphine (BUP). However, people with OUD have historically been excluded from insomnia clinical trials, leaving clinicians without evidence-based treatment options for this patient population. Lemborexant, the Food and Drug Administration (FDA)-approved dual orexin receptor antagonist for the treatment of insomnia, was recently shown to be safe and tolerable among a sample of patients with insomnia who were maintained on BUP. We hypothesise that pharmacologically antagonising the orexin system with lemborexant may improve insomnia symptoms in individuals with OUD and also enhance BUP treatment benefits by improving performance in neurofunctional domains identified in the National Institute on Drug Abuse Phenotyping Assessment Battery.
Participants with insomnia and OUD who have been stabilised on BUP for at least 4 weeks will be randomly assigned to receive either lemborexant (n=50) or placebo (n=50) for 8 weeks. Participants will complete assessments at baseline, during the 8-week intervention, postintervention and at a 2-week follow-up. Primary outcomes are insomnia severity and impulsivity. Secondary measures include objective sleep metrics (total sleep time, sleep efficiency, sleep onset latency and wake after sleep onset) and performance in the neurofunctional domains of negative emotionality and metacognition.
The study was approved by the Virginia Commonwealth University Institutional Review Board in April 2025 (protocol number HM20031777). Data collection began in May 2025 and is expected to be completed by May 2029. The trial is conducted under FDA IND no. 154797 (FGM). The dissemination plan for the trial includes presentations at local and national conferences, submission of primary and secondary outcome manuscripts for publication in peer-reviewed journals and circulation of findings to popular media outlets, as available. Results will also be shared with interested participants and clinical collaborators upon completion of the trial.
Migraine is a primary headache showing a multifactorial component that includes altered pain processing, psychological/emotional problems, neurocognitive and executive function deficits, all with a possible genetic association. The aim of the current study will be to evaluate the association between sensitisation, psychological/emotional, neurocognitive and genetic profile on conditioned pain modulation (CPM) in women with migraine from a multidisciplinary perspective.
A cross-sectional observational case–control study including 90 women with chronic migraine, 90 women with episodic migraine and 90 women without migraine (as controls) will be conducted. Clinical variables (disability, pain), processing (sensitisation-associated, neuropathic-like symptoms), psychological/emotional (anxiety, depression, sleep quality, catastrophising), neurocognitive (attention), executive functions (memory, mental inhibition, speed processing) and genetics (Val158Met polymorphism rs4680 gene) will be assessed in all subjects by healthcare professionals. Subsequently, CPM will be evaluated with the cold-pressor test paradigm by assessing changes obtained in mechanical and thermal stimuli. The association of each group of variables on CPM will be analysed with multivariate analyses (OMNIBUS analysis of variance). A network model will also be created to identify those variables showing the greatest key measure of centrality with the rest of the severity indicators (strength, intermediation and closeness) to establish the potentially therapeutic targets in patients with migraine from a multidisciplinary point of view.
The protocol of the current study has been approved by the Ethics Committee of all involved institutions (Hospital Universitario Fundación Alcorcón 24–117, Universidad Rey Juan Carlos 010220240912024). All procedures will be conducted following the Declaration of Helsinki. Participants will be informed of the aims and procedures of the study and will receive the informed written consent which should be signed before their inclusion. Study results will be disseminated through peer-reviewed publications and presentations at scientific meetings.
Violence against girls and women (VAWG) is a public health problem and a violation of human rights. The prevalence of different forms of VAWG indicates that this is a recurring global issue that provokes economic, social and health consequences. In this paper, we outline a scoping review protocol to characterise risk factors for VAWG from an intersectional and intergenerational perspective and discuss the consequences of such experiences for women’s health.
The protocol will be conducted according to the Joanna Briggs Institute Methodology for Scoping Reviews and will involve six consecutive steps: (1) formulating the research question, (2) search strategy, (3) study selection, (4) eligibility criteria, (5) data extraction, (6) data analysis and presentation of results and (7) stakeholder consultation. The search strategy will include eight indexed databases (PubMed, BVS, Scopus, Web of Science, EMBASE, Cinahl, Cochrane Library and PsycInfo) and recommendations from professional organisations and international agencies. The search will be limited to publications in English, Spanish and Portuguese, according to the Health Sciences Descriptors/Medical Subject Headings and free terms. Two independent researchers will select articles based on the inclusion criteria, and a third author will be consulted to establish consensus. Data extraction will involve a form with information on study characteristics, methodological issues and main results from the sources of evidence. Extracted data will be analysed using descriptive and content analysis. The NVIVO 14 software will be used to organise and validate the data. The protocol was registered in the Open Science Framework (DOI 10.17605/OSF.IO/P6H2S).
Ethical approval is not required as data from publicly available literature sources will be used. The results will be disseminated through publications in scientific journals and presentations of the evidence to stakeholders.
