Its role in the setting of large vessel occlusion (LVO) is underutilized due to the limited availability of magnetic resonance imaging (MRI) in the emergency settings. However, it might serve as an useful adjunct to other perfusion modalities in future. Objective: To study ASL perfusion patterns in anterior circulation LVO stroke and evaluate the presence of arterial transit artefacts (ATA) as a surrogate marker of collaterals. Methods: We performed a retrospective analysis of our mechanical thrombectomy database over the last 2 years for acute stroke cases in which ASL perfusion as part of MRI was performed. ASL perfusion patterns in acute LVO stroke were reviewed, with respect to presence of ATA and diffusion-weighted imaging (DWI)-ASL mismatch. Inter-rater reliability was analyzed between 2 readers of varying experience. Baseline variables were analyzed between those with and without ATA. Results: Out of 95 patients, 78 had anterior circulation occlusions, among which 27 had ASL. Type I (with ATAs) was seen in 11 patients and all of these had DWI mismatch. Type II (without ATAs) was seen in 16 patients. Of these, 15 had mismatch with DWI and only 1 had no mismatch. Inter-rater reliability for the detection of ATA on ASL was substantial (Cohen’s k—0.64). No statistical significance was noted between ATA and clinical outcomes. Conclusion: ASL patterns vary amongst patients with LVO stroke and can be classified based on the presence of ATA since resulting DWI mismatch actually indicates a pseudo-perfusion deficit.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":"6 1","pages":"72 - 80"},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85170943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stroke is one of the leading causes of death and disability in the world. Asia has a diverse health system and more than two-thirds of strokes occur in this region. The Asian Stroke Advisory Panel (ASAP) conducted a survey among the member countries to explore the impact of COVID-19 on stroke care. The stroke admission numbers have fallen, as have the number of patients who received thrombolysis and mechanical thrombectomy. The stroke unit and rehabilitation beds have been reallocated for COVID-19 care. ASAP recommends emergency department screening of stroke patients for COVID-19 and protected stroke code to be activated for COVID-19 suspect stroke patients. Noncontrast computed tomography (CT), CT angiography, and CT chest are the imaging modalities of choice. All health care professionals involved in triaging, imaging, and stroke care should wear appropriate personal protective equipment. All eligible stroke patients (COVID suspect/positive/non-COVID) should receive intravenous thrombolysis/mechanical thrombectomy. Mobile stroke units and robots can be used wherever available for evaluation and triaging. All stroke patients should receive standard stroke unit care. Limited rehabilitation should be offered to patients and training of caregivers if needed. Telemedicine/telestroke should be used for rehabilitation and follow-up. The ASAP consensus statement can be adapted to suit local and national health care systems.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":"59 1","pages":"7 - 14"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73573580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spasticity and connective tissue changes around ankle, limits dorsiflexion, and interferes with balance and gait performances. Improving functional range of dorsiflexion is essential in post-stroke rehabilitation. Objectives: This meta-analysis analyzed the effects of ankle mobilization techniques in improving dorsiflexion range and gait parameters among chronic stroke survivors. Method: Articles published up to July 2020 were searched in CINAHL, PubMed, Embase, PsyINFO, and OpenGrey. English version of randomized controlled trials (RCTs) assessing the effects of ankle joint mobilization among chronic stroke subjects, with dorsiflexion range of motion (ROM) and gait parameters as outcome, were included. Characteristics of participants, interventions, outcome measure, and measures of variability were extracted. Methodological quality of included trials was assessed using PEDro scale and Cochrane Collaboration tool for the risk of bias. Pooled standardized mean difference was calculated using random effects model for dorsiflexion ROM, gait velocity, step length, cadence, and timed up and go (TUG). Results: Eight RCTs including 226 stroke patients, with mean methodological score of 6 out of 10 in PEDro, were eligible for this meta-analysis. Ankle joint mobilization demonstrated statistically significant improvement on passive dorsiflexion ROM, gait velocity, step length (affected side), and cadence outcomes. Nonsignificance was found in step length (unaffected side) and in TUG. Conclusion: The ankle mobilization techniques are effective in improving passive dorsiflexion ROM, gait velocity, and cadence in chronic stroke survivors. However, the retention effect of ankle mobilization among stroke subjects is not known.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":"61 1","pages":"15 - 24"},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77798007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Caregiving for stroke survivors is associated with caregiver burden. Knowledge of factors influencing this caregiver burden is important for both the patient and the caregiver. Aim: To study the prevalence and predictors of major caregiver burden in survivors of moderate to severe stroke treated both conservatively and with surgical decompression. Methods: A community-based cross-sectional study where caregivers of stroke survivors with moderate to severe disability at discharge (modified Rankin Scale >3) were assessed between 3 months and 3 years of discharge. Results: Caregivers of 115 stroke survivors (82 conservatively treated and 33 who underwent decompressive hemicraniectomy) were studied. The majority (80%) were females. The mean period of caregiving was 18.8 ± 10.3 months (range 3-44 months). Major caregiver burden was seen in 36% (confidence interval [CI] = 27.3-44.7%). The significant predictors of major caregiver burden were daily caregiving for ≥4 hours (adjusted odds ratio [AOR] 5.3; CI = 1.84-15.3), patient activities of daily living dependency (AOR 3.66; CI = 1.03-13.03), and caregiver being the spouse (AOR 4.52; CI = 1.25-16.3). A total of 17% of the caregivers stopped working. Only (18%) had health insurance and 59% had borrowed money for treatment. A total of 88% of caregivers were happy regarding their decision to opt for surgery despite their current burden. Conclusion: Caregivers had stress in various domains. Shortening the caregiving hours especially in the initial months may help reduce the burden since the caregiver burden is also influenced by the patient’s dependency which improves over time.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":"65 1","pages":"34 - 43"},"PeriodicalIF":0.0,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77847008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inherited deficiencies of AT III are rare and pose a risk of developing venous thromboembolic disease. They can be subdivided into type I (quantitative) or type II (qualitative). Mild AT III deficiency is associated with a 2.4- to 3.5-fold risk of venous thromboembolism (VTE). Thrombosis in patients with AT III deficiency predominantly manifests as a deep vein thrombosis and may subsequently present as pulmonary embolism. It can also occur in uncommon sites such as cerebral, retinal, mesenteric, portal, hepatic, and splenic veins. We report a case of an unprovoked cerebral venous thrombosis in a 24-year-old Omani male, without any comorbidity, who was found to have quantitative deficiency of AT III. He has a significant history of family members having VTE in varying venous beds. This case highlights the wide spectrum of clinical manifestations of quantitative deficiency of AT III and stresses on the importance of taking a good family history and the need for testing for inherited thrombophilia since it can alter long-term management.","PeriodicalId":93323,"journal":{"name":"Journal of stroke medicine","volume":"153 1","pages":"67 - 71"},"PeriodicalIF":0.0,"publicationDate":"2021-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78203258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The aim of this study was to evaluate the safety of anticoagulation prescribing following a nontraumatic ICH with VKA, low molecular weight heparin (LMWH), or direct oral anticoagulants (DOACs). Methods: A retrospective chart review was conducted of patients admitted with a nontraumatic ICH and an indication for anticoagulation between February 2015 to June 2018 at an urban tertiary comprehensive stroke center. The primary objective was to evaluate the safety of prescribing anticoagulation in these patients. Two groups were reviewed to evaluate the primary outcome: patients who were started on anticoagulation after ICH (anticoagulation group) and a comparator group not started on anticoagulation (control group). The primary endpoint was measured by a composite incidence of recurrent ICH, major bleeding events, and thromboembolic events. Results: Anticoagulation was started within 2 months in 23 patients with an indication for anticoagulation. Anticoagulation was held in 35 patients.
