To assess how preoperative anaemia affects surgical outcomes in elderly patients within a resource-limited setting.

Prospective cohort study.

Two comprehensive specialised hospitals in Ethiopia.

Participants consisted of 224 patients aged 65 years and older who underwent surgery between 1 December 2024 and 29 March 2025.

Perioperative blood transfusions were the primary outcome. Secondary outcomes included intensive care unit (ICU) admission, risk of postoperative complications, prolonged hospitalisation, poor recovery quality and in-hospital mortality.

The anaemic group required transfusions of three or more units more frequently than the non-anaemic group (10.5% vs 2.6%; absolute risk difference 8.0%). Their perioperative transfusion rates were significantly higher (42.3% vs 18.4%; p

Preoperative anaemia significantly increases the risk of transfusion, poor recovery, ICU admission, prolonged hospitalisation and in-hospital mortality in older patients who underwent surgery. In resource-limited settings, improving perioperative outcomes should prioritise the early detection and treatment of anaemia.

National Immunization Technical Advisory Groups (NITAGs) are multidisciplinary groups of national experts who provide independent advice to policy makers on issues related to immunisation and vaccines, based on evidence and the national context. On the other hand, academic institutions can be described as organisations dedicated to education and research. These include schools, colleges, universities and research centres that offer formal education, conduct scholarly research and contribute to knowledge in various fields. NITAGs can enhance their capacity by linking with academic institutions and leveraging scientific expertise in research, data analysis, modelling, resource procurement and management, and policy formulation. The proposed landscape analysis will explore the links between NITAGs and academic institutions, especially in the sub-Saharan African context, and, where such exist, document their characteristics and identify benefits, challenges and best practices for fostering such linkages.

This landscape analysis will use an adaptation of the WHO’s quick guide manual on ‘Performing a landscape analysis: Understanding health product research and development’. The planned landscape analysis will be conducted in two parts. The first part will entail a review of published literature to identify relevant documents on linkages between NITAGs and academic institutions. The second part will entail conducting key informant interviews with NITAG members, partners and other identified key stakeholders in two study countries: Ethiopia and Zambia. The transcribed scripts will be thematically analysed. The findings from both parts will be synthesised and presented as a descriptive landscape analysis report.

The protocol of the parent study has been reviewed and approved by the Human Research Ethics Committee of the University of Cape Town (Reference 417/2025). It has also been approved by the Biomedical Research Ethics Committee of the University of Zambia (REF. NO. 6760-2025) and the Ethiopian Public Health Association (EPHA/06/392/25). The landscape analysis report will be submitted to the commissioning funder (Gavi, the Vaccine Alliance) and will also be published in a peer-reviewed journal.

Growing evidence points towards the integral role of both central and peripheral inflammation across all neurodegenerative diseases, including dementia with Lewy bodies (DLB) and Alzheimer’s disease (AD). The immune alterations observed in these diseases may occur long before the onset of clinical and cognitive symptoms; however, the exact timing and role of inflammation in the pathogenesis of neurodegenerative disease remains unclear. Findings to date are conflicting, with most work focused on AD rather than other dementias and most studies from single sites and cross-sectional. Through longitudinally examining detailed phenotypes of the peripheral immune system using mass cytometry, the Immune Profiling in Early Cognitive Disorders study aims to uncover specific immune signatures in early AD and DLB, how these signatures change over time and how they relate to disease progression and cognitive changes.

Blood, cerebrospinal fluid, saliva and urine samples will be collected from a cohort of participants with either prodromal (mild cognitive impairment) or early dementia due to Lewy bodies or AD (MCI-LB and DLB; and MCI-AD and AD), alongside healthy controls. Through immunophenotyping with mass cytometry, detailed immune fingerprints will be identified for these groups. We will assess which key combinations of immune cell clusters are predictive of disease phenotype, cognitive decline and progression to dementia. Samples will also be evaluated with novel techniques to measure markers of degenerative pathology and inflammation.

This study was approved by the Preston North West Research Ethics committee (21/NW/0314) and is registered with the ISRCTN registry (ISRCTN62392656). The study is ongoing (since June 2022). Baseline visits are being undertaken, and follow-up visits have started for some participants. Full data analyses will be completed and submitted for publication upon conclusion of the study.

Internalised racism (IR) is broadly defined as the acceptance of negative racial stereotypes, beliefs and attitudes about one’s own racial or ethnic group. IR is increasingly recognised as a critical component and consequence of racial stress and trauma. Although IR has been linked to a variety of adverse mental and physical health outcomes, the phenomenon remains under-represented in intervention research. This scoping review addresses this gap by systematically mapping the range of interventions and intervention components that explicitly target IR among racially or ethnically minoritised communities and their health-related outcomes. This protocol paper will describe the process of the scoping review.

This review will follow methodology from the Joanna Briggs Institute and report using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. Using identified controlled vocabulary and keywords, searches will be undertaken using the following databases: MEDLINE, PsycInfo, Embase and Web of Science. This review will include studies describing any intervention or intervention component designed to reduce IR that is conducted with racially or ethnically minoritised populations in any context or setting. No date limit will be applied, and the study must be available in English. Conceptual or opinion pieces without a clear intervention framework will be excluded. Two reviewers will independently screen and select sources and extract data on intervention characteristics, theoretical underpinnings, outcomes and implementation details. Descriptive statistics will summarise study characteristics and outcomes, while a narrative synthesis will explore how interventions conceptualise and address IR. The findings will map existing approaches, highlight research gaps and inform future clinical practice and intervention development.

As this review uses published and publicly available data, no ethical approval is required. The findings will be disseminated through a peer-reviewed publication, conference presentations and briefs to stakeholder networks.

Assess the magnitude of adverse pregnancy outcomes and associated factors among mothers who had operative vaginal delivery in Amhara Region Comprehensive Specialized Hospitals, 2024.

A cross-sectional study was conducted from 1 November 2024 to 20 February 2025.

Seven comprehensive specialised hospitals were included in the study.

The study was employed on 389 mothers who had operative vaginal delivery.

Systematic sampling was used. Data were collected via questionnaires, chart reviews and observation. Data were entered into Epi Data V.4.6 and analysed using V.25 statistical package of social sciences. Variables with p

Adverse pregnancy outcomes of operative vaginal delivery.

Adverse pregnancy outcomes of operative vaginal delivery were 42.2%. Among them, 46 (11.8%) had only maternal complications, 55 (14.1%) had only neonatal complications and 63 (16.2%) had both maternal and neonatal complications. Perineal tear 29 (7.5%) and episiotomy extension 31 (8%) were the most common maternal complications, while caput succedaneum 45 (11.6%) was the most neonatal complication. The most common indication of operative vaginal delivery was prolonged second stage 203 (52.2%). Vacuum-assisted delivery (AOR 0.53; 95% CI 0.29 to 0.96), two tractions (AOR 2.19; 95% CI 1.23 to 3.90), birth weight less than 2.5 kg (AOR 1.85; 95% CI 1.21 to 2.83) and mid fetal station (AOR 2.9; 95% CI 1.49 to 5.64) were significantly associated with adverse pregnancy outcomes.

Adverse pregnancy outcomes following operative vaginal delivery were high. Type of instrumental vaginal delivery, number of tractions, fetal birth weight and fetal station were significantly increased risks. Therefore, operators should minimise traction attempts during operative vaginal delivery to reduce adverse outcomes.

Advancements in technology for treating diabetes mellitus (DM) are progressing rapidly. With the growing availability and use of continuous glucose monitoring (CGM) systems and continuous subcutaneous insulin infusion (CSII), glucose regulation is improved in individuals with DM, which will lead to less long-term complications and reduce the overall disease burden on patients with DM. Collecting vast amount of biomedical data, these devices combined with clinical outcome data provide more insight into the development and treatment of the disease. The objective of the DIABASE initiative is to collect and examine real-world data from medical devices and clinical practice in a registry.

The ongoing study is structured as an observational study registry. Clinical data and real-world data from diabetes wearable devices, such as CGM and CSII, are aggregated in the database. Clinical data is automatically extracted from the hospital’s electronic health record. Data from wearables is periodically collected manually from the various online data platforms for sharing and automatically added to the database.

This study is exempted from ethics approval by the Medical Research Ethics Committees United (MEC-U) since participants are not subject to procedures and are not required to follow rules of behaviour (approval ID: AW23.009/W20.197). The execution of this study has been approved by the board of the study site Hospital Group Twente (ZGT) (ZGT20-40). Results will be shared through scientific meetings and publications and through articles for the general public.

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.

This review aims to map oral health plans, programmes and policies worldwide in countries with universal health coverage.

This protocol describes a scoping review that will follow the Joanna Briggs Institute methodology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review checklist, guided by the PCC framework: Population—countries with universal health coverage (78 globally recognised); Concept—oral health plans, programmes and policies; Context—integration into health systems. Searches will be conducted in MEDLINE (PubMed), Scopus, Web of Science, Embase, Health System Evidence and Epistemonikos, with no restrictions on date, language or study type. Grey literature will be accessed through Google Scholar, OpenThesis and the Brazilian Digital Library of Theses and Dissertations. Official documents from ministries of health and international bodies, including the WHO and the International Monetary Fund, will also be reviewed. Two independent reviewers will screen titles and abstracts; a third will resolve disagreements. Eligible records will undergo full-text review. Data will be extracted into predefined categories reflecting health system components: population, structure, services, governance and oral health indicators. Results will be presented using tables, charts and figures to illustrate strategies and innovations.

This review does not involve primary data collection and does not require ethical approval. Results will be disseminated through a peer-reviewed publication and presentations at academic conferences and scientific events.

Sugar-sweetened beverages (SSBs) are sugary drinks such as sodas, fruit drinks and sweetened teas and are the leading source of added sugars in the American diet. SSBs are also linked to chronic diseases like type 2 diabetes, cardiovascular disease and certain cancers. Despite their well-known health risks, SSB consumption remains high in the United States of America (USA), with 63% of adults consuming them daily, often exceeding the recommended limit of 50 g of added sugar per day. Though efforts to reduce SSB intake through educational programmes, policy initiatives and taxes exist, further research is needed to assess the effectiveness of interventions to reduce SSB consumption in the USA. Understanding the role of behavioural interventions in lowering SSB consumption among adults is critical to address public health strategies.

The proposed scoping review will be conducted in accordance with the Joanna Briggs Institute methodological framework for scoping reviews. An advanced search will be conducted in three electronic databases: PubMed, PsycINFO and Scopus. The reference lists of included studies will also be reviewed to identify additional relevant literature. All identified citations will be compiled in EndNote, and duplicate citations will be eliminated. Identification of studies will occur through the three-step search process: (1) initial screening of studies according to inclusion criteria, (2) eligibility determined through full-text assessment and (3) inclusion of qualified studies meeting the criteria. To be included, studies must report on an existing behavioural intervention to reduce SSB consumption. All studies will undergo screening by two independent reviewers. Any disagreements that arise will be resolved through discussion or with an additional reviewer. A data extraction tool has been developed to extract relevant data from all eligible studies. The extracted data will be presented in a diagrammatic form, alongside a narrative summary, in line with Preferred Reporting Items for Systematic Reviews and Meta-Analysis: extension for Scoping Reviews reporting guidelines.

Ethics approval was not sought as all data will be collected from published literature. We will present our findings at relevant conferences and submit manuscripts for publication in peer-reviewed journals.

In the UK, approximately 5.4 million adults live with asthma, of whom one in five have an uncontrolled form. Uncontrolled asthma reduces quality of life and increases healthcare use. Engaging with peers through online health communities (OHCs) can empower patients to self-manage their long-term condition. While OHCs have been in existence for several years and growing numbers of patients access them, the role of primary care in signposting patients to them has been minimal and ad hoc. We have co-developed with patients and healthcare professionals (HCPs) an intervention for adult patients with asthma, consisting of an appointment with a primary care HCP to introduce online peer support and sign patients up to an established asthma OHC, followed by OHC engagement. Feasibility work found the intervention acceptable to patients and HCPs. This protocol outlines our plan to test the intervention’s effectiveness and cost-effectiveness.

An individual randomised controlled trial will be carried out. Eligible participants will be recruited via an online survey sent to adult patients on the asthma register in 50–70 general practices in several UK locations. Participants will be invited to attend a one-off, face-to-face appointment with a primary care HCP, during which they will be individually randomised to the intervention or usual care. An asthma control test (primary outcome) and other measures of clinical effectiveness will be collected at baseline and every 3 months over a 12-month follow-up period. Descriptive and inferential statistics will be used to compare outcome measures between study arms. Cost-effectiveness assessment of the intervention compared with current standard of asthma management in primary care will be reported. A sample of patients and HCPs will be interviewed at study exit and the data analysed thematically.

The study was approved by a National Health Service Research Ethics Committee (reference: 25/NE/0006). Written consent will be obtained from all participants. Findings will be disseminated through various means, including sharing with general practices, conference presentations and peer-reviewed publications.

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.

To assess the incidence of delirium and its predictors among adult patients admitted to the intensive care units of comprehensive specialised hospitals in the Amhara region of northwest Ethiopia from 18 October 2024 to 20 February 2025.

A multicentre prospective observational study was conducted.

Four comprehensive specialised hospitals in the Amhara region of northwest Ethiopia, from 18 October 2024 to 20 February 2025.

A total of 351 patients were included in the final analysis during the study period.

The primary outcome measure of this study was the incidence of delirium. Additionally, the study investigated the factors associated with delirium incidence among adult patients admitted to intensive care units.

The incidence of delirium among adult patients in intensive care units was 42.17% (95% CI: 37.08 to 47.42). Pain (adjusted HR (AHR) = 4.74; 95% CI: 2.38 to 9.44), mechanical ventilation (AHR = 2.96; 95% CI: 1.56 to 5.63), age 65 years or older (AHR = 2.18; 95% CI: 1.48 to 3.21) and agitation (Richmond Agitation-Sedation Scale (RASS) ≥1) (AHR = 3.26; 95% CI: 2.09 to 5.09) were statistically significant factors associated with delirium.

In the present study, more than one-third of patients developed delirium. Pain, mechanical ventilation, age 65 or older and agitation (RASS≥1) were significantly associated with delirium occurrence. To reduce the incidence of delirium, the current study recommends treating or preventing pain and agitation. Additionally, special attention should be given to patients receiving mechanical ventilation and those aged 65 or older during care.

Ischaemia reperfusion injury (IRI) is inevitable in kidney transplantation and negatively affects patient and graft outcomes. Anaesthetic conditioning (AC) refers to the use of anaesthetic agents to mitigate IRI. AC is particularly associated with volatile anaesthetic (VA) agents and to a lesser extent to intravenous agents like propofol. VA like sevoflurane interferes with many of the processes underlying IRI and exerts renal protective properties in various models of injury and inflammation. We hypothesise that a sevoflurane-based anaesthesia is able to induce AC and thereby reduce post-transplant renal injury, reflected in improved graft and patient outcome, compared with a propofol-based anaesthesia in transplant recipients of a deceased donor kidney.

Investigator-initiated, multicentre, randomised, controlled and prospective clinical trial with two parallel groups. The study will include 488 kidney transplant recipients from donation after brain death (DBD) or donation after circulatory death (DCD) donors. Participants are randomised in a 1:1 design to a sevoflurane (intervention) or propofol (control) group. The primary endpoint is the incidence of delayed graft function in recipients of DCD and DBD donor kidneys and/or 1-year biopsy-proven and treated acute rejection. Secondary endpoints include functional delayed graft function defined as failure of serum creatinine levels to decrease by at least 10% per day for three consecutive days; primary non-function is defined as a permanent lack of function of the allograft; length of hospital stay and postoperative complications of all kinds, estimated glomerular filtration rate at 1 week and 3 and 12 months calculated with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula; readmissions at 3 and 12 months, graft survival and all-cause mortality at 12 months.

The study is approved by the local ethical committees and national data security agencies. Results are expected to be published in 2025.

Black adults are generally exposed to more stressors over the life course and, due to the intersections of racism and economic and social resources, they tend to have more limited resources to cope with social stressors than white adults. This mismatch between stress exposures and resources may lead to dysregulated responses or reactivity to stressors and contribute to persistent racial disparities seen in adverse pregnancy outcomes (APOs). Prior studies examining stress exposures have been hampered by the challenge of capturing stress exposures comprehensively, given they are manifold, dynamic and accumulate over time. The Stress Reactivity and Maternal Health Study seeks to overcome this limitation by examining the impact of physiological and psychological stress reactivity to everyday stressors on APOs.

We are recruiting 700 nulliparous self-identified non-Hispanic black and white pregnant individuals from academic medical centres in the USA. We use ecological momentary assessments administered via smartphones to collect repeated measurements of exposure to everyday stressors throughout the day over the course of seven consecutive days at two different time points mid-pregnancy (14–22 weeks and 22–28 weeks). At the same time, we collect intensive measurements of heart rate variability, blood pressure, salivary cortisol and positive and negative affect. We will use mixed-effects models to estimate personalised indicators of cardiovascular, neuroendocrine and affective reactivity to everyday stressors. We will then use linear and logistic regression modelling to examine associations of these personalised indicators of stress reactivity with placental histological lesions and the occurrence of APOs. Finally, we will use the gap-closing estimand method to quantify the extent to which racial disparities in adverse placental and pregnancy outcomes are explained by differences in prenatal stress exposure and prenatal stress reactivity.

The Northwestern University institutional review board (IRB) approved this study and serves as the single IRB of record (STU00218683). All participants will sign an informed consent document prior to participation, and data will be treated confidentially. Findings will be disseminated in peer-reviewed scientific journals, briefs, infographics and presentations.
