CT Perfusion in lacunar stroke: a powerful tool to enhance lacunar stroke detection and prediction of patients' outcome.2 weeks agoLacunar strokes are caused by occlusion of small penetrating arteries. Although CT perfusion (CTP) is widely used in the acute settings, automated core/penumbra software often fails to detect lacunar perfusion abnormalities, so its diagnostic and prognostic roles remain unclear. This study aimed to assess the ability of CTP to detect perfusion asymmetries in patients with lacunar stroke and to determine whether such asymmetries are associated with clinical characteristics and functional outcomes.
We retrospectively analyzed 68 patients with lacunar stroke who underwent whole-brain CTP within 4.5 h from stroke onset or recognition. CTP maps (MTT, CBF, CBV, and summary) were visually assessed. Demographic, clinical and imaging data along with stroke metrics and outcomes measurements were collected. Statistical analyses explored CTP detection rate, the association between admission variables and the presence of CTP asymmetries and between these asymmetries and 3-month mRS (dichotomized as either mRS 0-1 or ≥ 2).
41.18% of patients exhibited CTP-detected asymmetries, with the MTT map showing the highest detection rate (39.71%). No demographic or clinical factors predicted CTP positivity. The presence of CTP asymmetries was associated with larger infarct volumes and was independently associated with lower odds of excellent functional recovery (3-month mRS 0-1) (OR 0.232; p = 0.012).
Qualitative assessment of individual CTP maps, and especially of MTT map, improves detection of lacunar strokes, particularly with whole-brain coverage. Asymmetries may reflect impaired microvascular perfusion and predict worse outcomes. Therefore, CTP is a valuable diagnostic and prognostic tool in lacunar stroke.Cardiovascular diseasesAccessCare/ManagementAdvocacy -
Multi-domain identification of myocardial infarction incidence using explainable AI: the overlooked role of periodontal health.2 weeks agoMyocardial infarction (MI) is a major global health concern influenced by diverse risk factors. Despite growing evidence of oral-systemic connections, current MI models largely exclude oral health indicators, reflecting the longstanding separation between dental and medical paradigms. This study introduces a multidomain, interpretable machine learning framework that integrates detailed periodontal and oral hygiene variables, marking one of the first efforts to quantitatively incorporate these features into MI incidence identification. A population-based case-control dataset comprising 1,355 individuals and heterogeneous variables was used to train and evaluate seven supervised classifiers via nested cross-validation. Among them, XGBoost achieved the best performance (AUC = 0.88 ± 0.01; F1 score = 0.74 ± 0.03) and was further probability-calibrated using isotonic regression, yielding a mean Brier score of 0.14 ± 0.01 and demonstrating well-aligned predicted probabilities. SHAP values confirmed the importance of conventional cardiovascular predictors, while several periodontal indicators such as mean clinical attachment loss, plaque index, and gingival bleeding emerged among the most influential features. Sex-stratified SHAP analysis revealed sex-specific patterns in the relative impact of oral features. Additionally, individual-level waterfall plots illustrated how oral inflammation may contribute independently or in combination with conventional factors to MI incidence identification. These findings support a systems-level view of periodontitis as a modifiable, biologically relevant factor in cardiovascular health and underscore the value of considering oral-health markers within screening and management frameworks.Cardiovascular diseasesAccessCare/ManagementAdvocacy

A multi-paradigm and longitudinal EEG dataset including the "sixth-finger" and "affected-hand" motor imagery of stroke patients.2 weeks agoMotor imagery-based brain-computer interface (MI-BCI) applications in stroke rehabilitation aim to match brain activity with real-time feedback, thereby establishing closed-loop neural pathways and providing a basis for evaluating patients' neuroplasticity changes. Thus, constructing EEG datasets under MI paradigms is crucial for optimizing MI-BCI systems and understanding the neural rehabilitation process. However, the current limitations of single MI paradigms and the lack of relevant EEG datasets may restrict the accurate interpretation and effective application in stroke rehabilitation. This study collected EEG data from 24 stroke patients during MI tasks, including a novel "sixth finger" MI and an affected-hand MI paradigm. The dataset comprehensively covers the complete longitudinal stages of stroke rehabilitation: pre-training, post-training, and follow-up periods. The data materials include: (1) raw EEG data, (2) preprocessed data, and (3) patient clinical information. Preliminary analysis using classical machine learning algorithms (CSP + SVM and CSP + LDA) demonstrated an average classification accuracy between the two MI paradigms maintained at approximately 85%~86%. We anticipate that this dataset will facilitate research on MI-BCI paradigms and neuroplasticity for stroke, and contribute to the development of high-efficiency MI-BCI systems in the field of stroke rehabilitation.Cardiovascular diseasesAccessCare/Management

Preventing the next stroke: nurse-led decision and adherence coaching to empower people with stroke (StrokeCompass) versus usual care - study protocol for a stepped-wedge pilot trial.2 weeks agoRecurrent stroke prevention is important for people who have suffered a stroke or transient ischaemic attack (TIA), as they are at increased risk of having another stroke. Nevertheless, treatment adherence is often low. Therefore, the StrokeCompass project was initiated to enhance medication adherence by empowering individuals who have had a stroke to take an active role in recurrent stroke prevention and medication management. In accordance with the UK Medical Research Council (MRC) guidelines, a complex intervention was developed that integrated evidence-based decision aids and a personalised, nurse-led coaching programme. The present stepped-wedge cluster-randomised controlled study addresses the second phase of the MRC framework by pilot testing the feasibility and acceptability of the intervention in a clinical setting.
A total of 452 patients with a recent ischaemic stroke or TIA will be recruited over a period of 16 months from seven stroke units across Germany. The study centres will be randomised and sequentially crossed over from the control phase to the intervention phase in three time periods (4, 8 and 12 months after initiation) until all clusters have been exposed to both conditions. The intervention comprises four core elements: first, a decision coaching programme, second, a physician consultation to discuss treatment targets, third, an adherence coaching programme, and fourth, a web-based patient decision aid. Furthermore, we developed a preparatory training programme for nurses and physicians. Feasibility outcomes (eg, recruitment strategies, participation, implementation and utilisation of intervention) will be analysed descriptively, while preliminary estimates of effectiveness, measured by changes in risk factor targets (eg, blood pressure and low-density lipoprotein cholesterol levels), will be analysed according to the intention-to-treat principle. Furthermore, an economic evaluation will be conducted focusing on the implementation costs. These findings could prove pivotal in the subsequent planning and rationale for a full-powered effectiveness study.
The study has received ethical approval from the Ethical Committee of the University of Lübeck (reference 2024-522). We will disseminate the findings in peer-reviewed journals, at conferences, and on relevant patient websites.

Anakinra for intravenous immunoglobulin-resistant Kawasaki disease: a systematic literature review.2 weeks agoApproximately 10%-20% of patients with Kawasaki disease (KD) are resistant to intravenous immunoglobulins (IVIG) and are at increased risk of developing coronary artery aneurysms (CAA). A potential therapeutic role of anakinra (ANK) in refractory KD has been suggested. The aim of this work is to systematically review and critically appraise the available clinical evidence on the use of ANK in the treatment of IVIG-resistant KD, focusing on treatment indications, timing, dosage, efficacy on fever, inflammation, CAA and safety.
A systematic literature search was conducted across PubMed, Embase, Web of Science, Cochrane Library, Emcare, Academic Search Premier and Google Scholar from inception to 9 October 2025, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Eligible studies included all study designs reporting outcomes of patients with KD treated with ANK.
Thirty-two publications (31 identified through database search and one by cross-referencing) describing 81 patients were included. Most reports were single cases or small series, with two early-phase clinical trials. Treatment with ANK was associated with resolution of fever and systemic inflammation in 94.9% of patients. Complete CAA resolution was reported in 32% and stabilisation/dimensional reduction in 56.3%. No serious safety concerns were identified. However, these findings derive from heterogeneous and low-quality evidence and should be interpreted with caution.
In IVIG-resistant KD, ANK was effective in controlling systemic inflammation, although more data are needed to assess its efficacy on coronary outcomes. While these findings are encouraging in supporting consideration of ANK for refractory KD, larger randomised clinical studies are warranted to define optimal ANK timing of introduction and dosing, and to evaluate its long-term efficacy on cardiac outcomes.

Maternal weight and hypertension as risk factors for juvenile idiopathic arthritis: a prospective population-based pregnancy cohort study.2 weeks agoThe intrauterine environment may influence childhood immune-mediated disease risk. We investigated whether maternal prepregnancy body mass index (BMI), gestational weight gain (GWG) or hypertensive disorders during pregnancy (HDP) were associated with juvenile idiopathic arthritis (JIA) in children and whether genetic susceptibility modified associations.
We linked the Norwegian Mother, Father and Child Cohort Study (MoBa) to the Norwegian Patient Registry to identify children with JIA. Logistic regression estimated adjusted ORs (aORs) for associations with BMI, GWG and HDPs. Causal mediation analyses assessed whether hypertension mediated the GWG-JIA association. In a genotyped subsample, we tested interactions between exposures and a JIA Polygenic Risk Score (PRS).
Among 78 901 eligible children, 265 developed JIA (genotyped subsample: 192 JIA/44 053 non-JIA). By the end of follow-up, all children were ≥14 years old and 85% were ≥16 years old. Maternal prepregnancy BMI was not associated with JIA. Each 1 SD (~6 kg) increase in GWG was associated with modestly higher odds of JIA (aOR 1.12, 95% CI 1.00 to 1.26), particularly among women with prepregnancy obesity (aOR 1.40, 95% CI 1.10 to 1.77). Maternal hypertension and pre-eclampsia were associated with higher JIA risk (aOR 1.43, 95% CI 1.02 to 1.99 and aOR 1.61, 95% CI 1.10 to 2.37). Hypertension did not mediate the GWG-JIA association (p>0.05). Among children with lower PRS, maternal obesity was associated with a lower JIA risk (aOR 0.37, 95% CI 0.17 to 0.80).
Higher GWG and HDPs were independently associated with increased JIA risk. Genetic susceptibility may modify associations with maternal BMI, supporting a role for pregnancy health in JIA development.Cardiovascular diseasesMental HealthAccessCare/ManagementAdvocacy -
Social determinants of cardiovascular health: From prevention to care and emerging challenges.2 weeks agoCardiovascular disease (CVD) is the leading cause of mortality globally and imposes a substantial disease burden. Addressing the social determinants of health (SDOH) presents a critical opportunity to reduce CVD-related mortality and disability. In Japan, CVD constitutes a major cause of death and necessitates long-term care, with current guidelines now incorporating SDOH related to CVD, indicative of a growing interest in these determinants. This review outlines the definition and conceptual frameworks of SDOH, along with its key domains: (1) Economic stability, (2) Education access and quality, (3) Social and community context, (4) Health care access and quality, and (5) Neighborhood and built environment. In addition to these established determinants, we discuss emerging SDOH such as climate change and digital health technologies, which may reshape cardiovascular risk and potentially widen existing disparities. We also summarize existing epidemiological findings and implications for intervention strategies, and outline future perspectives, including the implications of genetic testing and related ethical, legal, and social issues, as well as strategies aimed at reducing health disparities. Overall, advancing equitable cardiovascular health will require continued research, greater recognition of the role of SDOH, and efforts to address these determinants, including improving understanding of SDOH among health care professionals and the public and strengthening the evidence base for CVD and SDOH.Cardiovascular diseasesAccess

The Family Heart Study: rationale, design and methodology.2 weeks agoThe Family Heart Study (FHS) aims to identify genetic risk factors associated with strong personal and familial premature cardiovascular disease (CVD) in Māori and non-Māori families in Aotearoa New Zealand, and to compare this high-risk cohort with heart-healthy controls.
Participants were recruited from Christchurch Hospital cardiology wards and Christchurch Heart Institute research cohorts. Clinical data included blood pressure, anthropometry and questionnaires on medical history and lifestyle. Blood samples were collected for genetic and biomarker analyses. Genotyping and deoxyribonucleic acid (DNA) methylation profiling were performed using commercial cardiovascular arrays.
To date, 472 individuals have been screened, with 28 meeting strict inclusion criteria for documented personal and family history of early-onset CVD. The cohort includes 25 NZ European and three Māori participants, with a mean CVD onset age of 46.6 years. Most participants (75%) had a history of myocardial infarction, and the median number of affected first-degree relatives was two. After quality control, 185,514 single-nucleotide polymorphisms and 454,608 DNA methylation sites were retained for downstream analyses.
The FHS represents a rare cohort with strong inherited susceptibility to premature CVD. Ongoing recruitment will support investigation of genetic and epigenetic contributors to early-onset CVD in New Zealand.Cardiovascular diseasesAccessCare/ManagementAdvocacy -
Promoting patient empowerment in chronic care: A scoping review of key facilitating factors.2 weeks agoChronic conditions represent a growing global health challenge, requiring ongoing management in which patients play an active role. Although patient empowerment is increasingly recognized as important, practical insights on how to support it remain limited. This scoping review aims to identify key factors promoting patient empowerment in managing chronic conditions.
A literature search was conducted in Medline, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus in March 2025. Studies were included if they described factors, strategies, interventions, experiences, or perspectives related to promoting patient empowerment in adults (≥18 years) with chronic conditions (i.e. cardiovascular diseases, osteoarthritis, respiratory conditions, and/or diabetes). Papers focusing on acute conditions, non-empirical work, studies without full-text availability, or those not published in English were excluded. Article screening was conducted using the artificial intelligence (AI)-based tool Automated Systematic Review (ASReview), applying the SAFE procedure to determine an appropriate stopping point.
The literature search yielded 29,929 articles, of which 66 were included in the final analysis. Key factors promoting patient empowerment included knowledge and skills education, personalized care planning and goal setting, social and peer support, patient-provider communication, and (remote) monitoring and follow-up. Additionally, digital tools, such as mobile health applications and online platforms, emerged as important facilitators.
This review shows that patient empowerment in chronic care can be promoted by multiple factors that appear broadly relevant across chronic conditions and healthcare contexts. Digital tools may further strengthen this process.
Future efforts should focus on bridging the gap between these theoretical insights and real-world practice.Cardiovascular diseasesAccess -
Effectiveness and safety of acetazolamide plus loop diuretics in acute congestive heart failure: A living systematic review - Version 2026 1.0.2 weeks agoThis living systematic review Version 1.0 aims to provide a timely, rigorous and continuously updated summary of the evidence on the use of acetazolamide plus loop diuretics in acute congestive heart failure compared to loop diuretics.
We conducted a comprehensive search in CENTRAL, EMBASE, MEDLINE, and between database inception and September 2025. No language, publication date or status restrictions were applied. Two reviewers independently screened eligible studies, according to predefined selection criteria, and extracted data using a predesigned form. We performed meta-analyses using random-effects models and assessed overall certainty in evidence using the GRADE approach. The quality of the evidence was assessed using the Cochrane risk-of-bias tool. This review was registered in PROSPERO (CRD42024575267).
Of 732 records identified, five randomized trials were included, with a total of 1050 participants. The evidence is very uncertain about the effect of adding acetazolamide to loop diuretics in decongestion observed at 72 hours (risk ratio: 1.17, 95% confidence interval: 0.96 to 1.44). Low certainty evidence shows adding acetazolamide to loop diuretics may increase natriuresis at 24 hours (mean difference 38.43, 95% confidence interval: 19.42 to 57.43). No significant differences were found between groups in accumulative diuresis at 48 hours, all-cause mortality, readmission due to heart failure or worsening renal function.
Evidence suggests that it is necessary to promote further investigations regarding the use of acetazolamide plus loop diuretics in acute congestive heart failure. More robust, standardized, long-term studies are needed, and conclusions may change as new data emerge.Cardiovascular diseasesAccessCare/ManagementAdvocacy
