- The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at (sic)23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

Tidskriftsartikel (refereegranskat)abstract
- Rationale: Cerebrovascular diseases associated with pregnancy and postpartum period are uncommon; however, they can have an important impact on health of both women and foetus or newborn. Aims: To evaluate the frequency, characteristics and management of cerebrovascular events in pregnant/postpartum women, to clarify pathophysiological mechanisms underlying the occurrence of these events including biomolecular aspects, and to assess the short- and long-term cerebrovascular and global cardiovascular outcome of these patients, their predictors and infant outcome. Methods and design: This is an observational, prospective, multicentre, international case–control study. The study will include patients with cerebrovascular events during pregnancy and/or within six months after delivery. For each included case, two controls will be prospectively recruited: one pregnant or puerperal subject without any history of cerebrovascular event and one non-pregnant or non-puerperal subject with a recent cerebrovascular event. All controls will be matched by age, ethnicity and type of cerebrovascular event with their assigned cases. The pregnant controls will be matched also by pregnancy weeks/trimester. Follow-up will last 24 months for the mother and 12 months for the infant. Summary: To better understand causes and outcomes of uncommon conditions like pregnancy/postpartum-related cerebrovascular events, the development of multisite, multidisciplinary registry-based studies, such as the Stroke in Pregnancy and Postpartum study, is needed in order to collect an adequate number of patients, draw reliable conclusions and give definite recommendations on their management.

Atrial fibrillation in cryptogenic stroke and transient ischaemic attack – The Nordic Atrial Fibrillation and Stroke (NOR-FIB) Study : Rationale and design
- 2019
-
Ingår i: European Stroke Journal. - : SAGE Publications. - 2396-9873 .- 2396-9881. ; 4:2, s. 172-180

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Paroxysmal atrial fibrillation is often suspected as a probable cause of cryptogenic stroke. Continuous long-term ECG monitoring using insertable cardiac monitors is a clinically effective technique to screen for atrial fibrillation and superior to conventional follow-up in cryptogenic stroke. However, more studies are needed to identify factors which can help selecting patients with the highest possibility of detecting atrial fibrillation with prolonged rhythm monitoring. The clinical relevance of short-term atrial fibrillation, the need for medical intervention and the evaluation as to whether intervention results in improved clinical outcomes should be assessed. Method: The Nordic Atrial Fibrillation and Stroke Study is an international, multicentre, prospective, observational trial evaluating the occurrence of occult atrial fibrillation in cryptogenic stroke and transient ischaemic attack. Patients with cryptogenic stroke or transient ischaemic attack from the Nordic countries are included and will have the Reveal LINQ® Insertable cardiac monitor system implanted for 12 months for atrial fibrillation detection. Biomarkers which can be used as predictors for atrial fibrillation and may identify patients, who could derive the most clinical benefit from the detection of atrial fibrillation by prolonged monitoring, are being studied. Conclusion: The primary endpoint is atrial fibrillation burden within 12 months of continuous rhythm monitoring. Secondary endpoints are atrial fibrillation burden within six months, levels of biomarkers predicting atrial fibrillation, CHA 2 DS 2 -VASc score, incidence of recurrent stroke or transient ischaemic attack, use of anticoagulation and antiarrhythmic drugs, and quality of life measurements. The clinical follow-up period is 12 months. The study started in 2017 and the completion is expected at the end of 2020.

Coprolalia in aphasic patients with stroke : a longitudinal observation from the BLAS2T database
- 2017
-
Ingår i: Neurocase. - : Informa UK Limited. - 1355-4794 .- 1465-3656. ; 23:5-6, s. 249-262

Tidskriftsartikel (refereegranskat)abstract
- The BLAS2T (bilingual aphasia in stroke-study team) initiative has been a multi-center attempt to investigate longitudinal changes in language function in a cohort of stroke subjects. This report discusses linguistic performance in four cases from the BLAS2T database who demonstrated coprolalia as an irresistible urge to say obscene words. Coprolalia was found to partly resolve in a 30-day follow-up in three cases. Recognition of coprolalia and language recovery patterns in bilingual aphasic patients with stroke would potentially lead to their even better individualized care and neurolinguistic/cognitive rehabilitation.

Microembolic signal counts increase during hyperbaric exposure in patients with prosthetic heart valves
- 2001
-
Ingår i: Journal of Thoracic and Cardiovascular Surgery. - : Elsevier BV. - 1097-685X .- 0022-5223. ; 122:6, s. 1142-1146

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Patients with prosthetic heart valves have an increased risk of thromboembolic events, and transcranial Doppler sonography reveals microembolic signals. Whereas microembolic signals were initially assumed to be of particulate matter, recent studies suggest that they are partially gaseous in origin. If this is true, alteration of environmental pressure should change microembolic signal counts. We undertook this study to evaluate the influence of hyperbaric exposure on microembolic signal counts in persons with prosthetic heart valves. METHODS AND RESULTS: Microembolic signal counts were monitored by transcranial Doppler sonography of both middle cerebral arteries under normobaria (normobaria 1), 2 subsequent periods of hyperbaria (2.5 and 1.75 bar), and a second period of normobaria (normobaria 2) in 15 patients with prosthetic heart valves. Each monitoring period lasted 30 minutes. Compression and decompression rates were 0.1 bar/min. Microembolic signal counts increased from 20 (12-78) at normobaria 1 to 79 (30-165) at 2.5 bar (P <.01 vs normobaria 1 and 2), decreased to 44 (18-128) at 1.75 bar (P <.01 vs normobaria 1 and 2.5 bar; P <.001 vs normobaria 2), and returned to 20 (8-96) at normobaria 2 (values are medians and 95% confidence intervals). CONCLUSIONS: Our results strongly suggest that gaseous bubbles are underlying material for part of the microembolic signals detected in patients with prosthetic heart valves.

Mechanism of ischemic infarct in spontaneous carotid dissection
- 2004
-
Ingår i: Stroke: a journal of cerebral circulation. - 1524-4628. ; 35:2, s. 482-482
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND PURPOSE: It is unclear whether stroke in patients with spontaneous dissection of the cervical internal carotid artery (ICAD) is due to thromboembolism or impaired hemodynamics. This study investigated the mechanism of stroke in ICAD by examining brain imaging and cerebrovascular findings of such patients. METHODS: We retrospectively evaluated the prospectively collected brain CT, MR, and ultrasound findings of 141 consecutive patients with 143 ICADs causing ischemic stroke. Eleven patients were not included because they had an inappropriate temporal bone window (n=6) or were treated with thrombolysis (n=5). Thus, the data of 130 patients (76 men, 54 women) with 131 ICADs were analyzed. RESULTS: All patients had territorial infarcts; 6 patients (5%) also had border-zone infarct patterns. Territorial infarcts affected the middle cerebral artery (MCA) in 130 of 131 cases (99%) and the anterior cerebral artery (ACA) in 1 case (1%). Additional vascular territories were affected in 8 patients with MCA infarcts (ACA, n=5 [4%]; posterior cerebral artery, n=3 [2%]). The pattern (hemodynamic versus thromboembolic) and extent of infarction were not influenced by vascular findings (MCA stenosis or occlusion, ACA occlusion, degree of obstruction in the dissected ICA, pattern of cross-flow in 115 patients with >80% ICA stenosis or occlusion). CONCLUSIONS: This study suggests that thromboembolism, not hemodynamic infarction, is the essential stroke mechanism in ICAD.

Tidskriftsartikel (refereegranskat)abstract
- The aim of the present case-control study was to investigate the role of migraine as a potential risk factor for a delayed ischaemic neurological deficit (DIND) after subarachnoid haemorrhage (SAH). A telephone interview was performed in patients or their relatives to determine the prevalence of migraine. Thirty-six women aged < 60 years had SAH with Hunt & Hess grade I-III and DIND (group A). This group was compared with an age-matched group of 36 female SAH patients, Hunt & Hess grade I-III without DIND (group B). The two populations were also characterized regarding hypertension, smoking, diabetes mellitus and alcohol use. A significant difference was only found for the prevalence of migraine with 47% in group A and 25% in group B (P < 0.05; odds ratio: 2.68, confidence interval: 0.99-7.29). Migraineurs revealed similar prevalences of risk factors independently of the presence of DINDs. This retrospective study suggests that women with migraine have a higher risk to develop a DIND than women without migraine.

Aspirin for Primary Stroke Prevention; : Evidence for a Differential Effect in Men and Women
- 2022
-
Ingår i: Frontiers in Neurology. - : Frontiers Media SA. - 1664-2295. ; 13

Tidskriftsartikel (refereegranskat)abstract
- Background: The use of aspirin for primary prevention of cardiovascular events in men and women remains controversial. Our study aimed to investigate the role of aspirin in primary stroke prevention in men and women and the effect of aspirin on risk of ischemic stroke in patients with covert cerebral small vessel disease (ccSVD).Methods: We performed systematic searches of the PubMed, and Cochrane Library databases, covering the period from the inception of each database to May 2021. The incidence of any ischemic stroke (IS) or hemorrhagic stroke (HS) was the main outcome. The incidence of stroke overall, both ischemic (IS) and hemorrhagic (HS), was the main outcome.Results: From 531 abstracts, 11 randomized control trials which assessed primary prevention of cardiovascular events in men and women were included. Only one study assessed the risk of aspirin in people with ccSVD. In women, there was significant decrease in the risk of stroke (OR 0.85 [95% CI 0.73, 0.99], p = 0.03) and IS (OR 0.76 [0.63, 0.93], p = 0.008) with aspirin compared to placebo while no increase in the risk of HS was found (OR 1.78 [0.61, 5.19], p = 0.29). In men, aspirin did not affect the risk of stroke (OR 1.13 [0.97, 1.31], p = 0.12) and IS (OR 0.94 [0.67, 1.32], p = 0.72) but increased the risk of HS with borderline statistical significance (OR 1.99 [0.99, 4.03], p = 0.05) compared to placebo. Aspirin significantly increased major bleedings in both sexes (p < 0.05). We found no evidence to support the use of aspirin in patients with ccSVD.Conclusion: Our meta-analysis suggests aspirin is effective in primary prevention of stroke and IS in women with no clear increased risk of HS. However, it was associated with an overall increased risk of bleeding. Aspirin is not recommended in ccSVD.

Sex and gender publications in brain health : a mapping review of the Asia-Pacific region
-
Ingår i: Cerebrovascular Diseases. - 1421-9786.
-
Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Reporting of sex and gender analysis in medical research has been shown to improve quality of the science and ensures findings are applicable to women and men. There is conflicting evidence on whether efforts by funding agencies and medical journals to encourage reporting of sex and gender analysis has resulted in tangible improvements. This study mapped the inclusion of sex and gender analysis in stroke and dementia research conducted in the Asia-Pacific region.METHODS: A systematic search for Asia-Pacific stroke and dementia research was conducted in PubMed and papers included from the period 2012 to 2022. Eligible studies were reviewed for inclusion of a primary sex or gender focus and categorized by type of sex and gender analysis. Author gender was determined using an algorithm and its associations with inclusion of sex and gender analysis examined.RESULTS: Total Asia-Pacific publications increased from 109 in 2012 to 313 in 2022, but the rate of studies with a primary sex or gender focus did not increase significantly (R2 = 0.06, F(1,9) = 0.59, p = 0.46). Australia, China, India, Japan and South Korea produced the most publications over the study period and were the only countries with at least 50 publications. The impact of author gender was mixed, with female first authorship associated with inclusion of sex or gender analysis and last female authorship associated with studies having a primary sex or gender focus.CONCLUSIONS: In the Asia-Pacific, brain health research is currently centered around high income countries and efforts are needed to ensure research findings are applicable through out the region. While there was a general increase in brain health publications over the last decade, the rate of sex and gender analysis was unchanged. This demonstrates that even with efforts in some countries in place, there is currently a lack of progress in the Asia-Pacific region to produce more research focusing on sex and gender analysis.
