Ponatinib is a third-generation Tyrosine Kinase Inhibitor (TKI), approved as first-line treatment for Chronic Myeloid Leukaemia (CML) chronic phase. Here we describe a CML patient with a history of subsequent TIAs and an ischemic stroke during Ponatinib treatment. Patient was admitted for a 3-day history of sudden onset left hemiparesis due to an acute ischemic stroke. selleckchem MRI showed bilaterally the almost total absence of signal in the intracranial tract of anterior circulation and low signal of cerebral posterior circulation. Digital Subtraction Angiography showed multiple steno-occlusions of both anterior and posterior circulation large vessels. The association between cerebrovascular events and TKIs of second and third-generation has been widely described. So Ponatinib was stopped. To our knowledge, this is the first case of multiple ischemic strokes and recurrent TIAs during treatment with Ponatinib, pointing out the importance of accurate quantification of cardiovascular risk before starting Ponatinib.

To assess whether smoking increases the risk of bleeding in patients with cerebral arteriovenous malformations (CAVM).

According to our research plan, 385 CAVM patients admitted to Beijing Tiantan Hospital from December 2015 to January 2018 were included in this study, including 210 bleeding patients and 175 non-bleeding patients. We divided patients into three subgroups of current smokers, ex-smokers (those who quit smoking for one year or more) and non-smokers. The relationship between smoking and the risk of CAVM rupture was assessed by univariate and multivariate regression analysis.

Multivariate regression analysis showed that there was a statistically significant difference between current smoker and non-smoker (OR = 1.87, p = 0.019). Among the covariates of the multivariate regression analysis, the location, combined with blood flow-related intracranial aneurysms and size were related to the risk of CAVM bleeding.

Current smoking may increase the risk of CAVM bleeding; however, there was no significant correlation between ex-smoking and CAVM bleeding.

There is relatively limited information on the risk factors and outcome of new onset Poststroke Anxiety (PSA) in Low- and Middle-Income Countries. We estimated incidence, cumulative incidence, risk factors and outcome of new onset anxiety in the first year of stroke among African stroke survivors.

We analyzed the dataset of a completed clinical trial comprising patients enrolled to test an intervention designed to improve one-year blood pressure control among recent (≤ one month) stroke survivors in Nigeria.Anxiety wasmeasured using the Hospital Anxiety and Depression Scale. Outcomes were assessed using the modified Rankin Scale (mRS), Community screening instrument for dementia (CSID) and Health Related Quality of Life in Stroke Patients (HRQOLISP-26).

Among 322 stroke survivors who were free of anxiety at baseline, we found a one-year cumulative incidence of 34% (95% CI = 28.6-39.3). Rates were 36.2% (95% CI =29.6-42.7) for men and 29.2% (95% CI =19.9-38.3) for women. In multivariate Cox regression analyses, haemorrhagic stroke type was associated with higher risk of new onset PSA (Hazard Ratio=1.52, 95% CI =1.01-2.29). New onset PSA was independently associated with cognitive [(mean difference (MD) in CSID scores=1.1, 95% C.I=0.2, 1.9)] and motor decline (MD in mRS scores= -0.2, 95% C.I= -0.4, -0.02), as well as poorer quality of life overtime (MD in total HRQOLISP-26 scores=3.6, 95% C.I=1.0, 6.2).

One in 3 stroke survivors in Nigeria had PSA at one year. Clinicians in SSA should pay special attention to survivors of haemorrhagic stroke as they are at higher risk of incident anxiety and therefore its consequences.

Cerebrovascular reactivity (CVR) to acetazolamide (ACZ) on single-photon emission computed tomography (SPECT) can be used to assess the severity of chronic cerebral ischemia; however, this is an invasive method. We examined whether whole-brain magnetic resonance angiography (MRA) at 7T could non-invasively detect impaired CVR in patients with chronic cerebral ischemia by demonstrating the leptomeningeal collaterals (LMCs).

Fifty-seven patients with symptomatic unilateral cervical stenosis underwent whole-brain time-of-flight MRA at 7T and cerebral perfusion SPECT before/after the ACZ challenge. MRA images were visually assessed based on 6-point grading systems to evaluate the development of LMCs toward the middle cerebral artery (MCA) and antegrade flow of MCA. CVR of the affected side was calculated from the SPECT data. Subsequently, we compared the LMC grades on MRA with CVR on SPECT.

CVR was significantly lower in grades ≥ 2 of LMCs than in grades 0-1 (P<0.05) when applying LMCs from the anterior cerebral artery (ACA) and/or posterior cerebral artery (PCA). These differences were more evident than those in the grading of the antegrade MCA flow. The LMC grades from ACA/PCA readily detected reduced CVR (< 18.4%) with a sensitivity/specificity of 0.79/0.82.

The development of LMCs on whole-brain MRA at 7T can non-invasively detect reduced CVR with a high sensitivity/specificity in patients with unilateral cervical stenosis.

Anterior circulation Large Vessel Occlusion (LVO) stroke comes with significant morbidity and mortality. With the advent of endovascular interventions, its management has revolutionized. For health authorities to build systems and allocate resources, its burden, predictors, and outcome must be determined.

In a single tertiary care center, we retrospectively collected data from 1495 ischemic stroke patients to determine anterior circulation LVO prevalence, predictors, and outcome. Patients must have radiologically proven ischemic stroke within 24 hours before arrival at the emergency department. Anterior circulation LVO related stroke was defined as evidence of new anterior circulation infarct detected on neuroimaging, and vascular imaging confirming anterior circulation Large Vessel Occlusion. Data on demographics, vascular risk factors, treatment with reperfusion therapy, modified Rankin Scale (mRS) at admission, National Institute of Health Stroke Scale (NIHSS) at admission, length of stay (LOS) in days, and in-hospital comorbidities and death were collected.
