Millard-Gubler Syndrome Associated with Cerebellar Ataxia in a Patient with Isolated Paramedian Pontine Infarction - A Rarely Observed Combination with a Benign Prognosis: A Case Report.

Case Rep Neurol 2021 Jan-Apr;13(1):239-245. Epub 2021 Apr 13.

Department of Neurology, College of Health Science, Addis Ababa University, Addis Ababa, Ethiopia.

Clopidogrel with aspirin in High-risk patients with Acute Non-disabling Cerebrovascular Events II (CHANCE-2): rationale and design of a multicentre randomised trial.

Stroke Vasc Neurol 2021 May 5. Epub 2021 May 5.

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Background: In patients with a minor ischaemic stroke or transient ischaemic attack (TIA), separate trials have shown that dual antiplatelet therapy with clopidogrel plus aspirin (clopidogrel-aspirin) or ticagrelor plus aspirin (ticagrelor-aspirin) are more effective than aspirin alone in stroke secondary prevention. However, these two sets of combination have not been directly compared. Since clopidogrel was less effective in stroke patients who were loss-of-function (LOF) allele carriers, whether ticagrelor-aspirin is clinically superior to clopidogrel-aspirin in this subgroup of patients with stroke is unclear.

Stroke 2021 May 5:STROKEAHA120032424. Epub 2021 May 5.

Department of Neurology, Beijing Tiantan Hospital, Capital Medical University, China (J.J., Y.S., A.W., Y.Z., Y.J., L.L., X.Z., Yilong Wang, Z.L., H.L., X.M., Yongjun Wang).

Background And Purpose: Whether imaging parameters would independently predict stroke recurrence in low-risk minor ischemic stroke (MIS) or transient ischemic attack (TIA) according to traditional score system (such as ABCD score, which was termed on the basis of the initials of the five factors: age, blood pressure, clinical features, duration, diabetes) remains unclear. We sought to evaluate the association between imaging parameters and 1-year stroke recurrence in patients with TIA or MIS in different risk stratum stratified by ABCD score.

Carotid Stenosis and Recurrent Ischemic Stroke: A Post-Hoc Analysis of the POINT Trial.

Stroke 2021 May 4:STROKEAHA121034089. Epub 2021 May 4.

Department of Neurology and Department of Psychiatry, University of Massachusetts Medical Center, Worcester (N.H.).

Background And Purpose: Randomized trials demonstrated the benefit of dual antiplatelet therapy in patients with minor ischemic stroke or high-risk transient ischemic attack. We sought to determine whether the presence of carotid stenosis was associated with increased risk of ischemic stroke and whether the addition of clopidogrel to aspirin was associated with more benefit in patients with versus without carotid stenosis.

Methods: This is a post-hoc analysis of the POINT trial (Platelet-Oriented Inhibition in New TIA and Minor Ischemic Stroke) that randomized patients with minor ischemic stroke or high-risk transient ischemic attack within 12 hours from last known normal to receive either clopidogrel plus aspirin or aspirin alone.

Parathormone levels add prognostic ability to N-terminal pro-brain natriuretic peptide in stable coronary patients.

ESC Heart Fail 2021 May 1. Epub 2021 May 1.

Department of Cardiology, IIS-Fundación Jiménez Díaz, Avda. Reyes Católicos 2, Madrid, 28040, Spain.

Aims: There are controversial data on the ability of the components of mineral metabolism (vitamin D, phosphate, parathormone [PTH], fibroblast growth factor-23 [FGF23], and klotho) to predict cardiovascular events. In addition, it is unknown whether they add any prognostic value to other well-known biomarkers.

Methods And Results: In 969 stable coronary patients, we determined plasma levels of all the aforementioned components of mineral metabolism with a complete set of clinical and biochemical variables, including N-terminal pro-brain natriuretic peptide (NT-proBNP), high-sensitivity troponin I (hs-TnI), and high-sensitivity C-reactive protein.

Carotid Stenting: Flow Reversal Technique: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 Apr 30. Epub 2021 Apr 30.

Department of Neurological Surgery, Mayo Clinic, Jacksonville, Florida, USA.

Management options for carotid stenosis include medical management, carotid endarterectomy, carotid stenting with distal filter protection, or stenting with either flow arrest or flow reversal techniques.1 Flow reversal with transcarotid artery revascularization (TCAR) technique represents a hybrid approach with surgical access to the common carotid for endovascular placement of a stent in the internal carotid artery. This direct access to the carotid artery avoids navigating the challenging anatomy of the aortic arch with endovascular devices. Read More

Cardiac implantable electronic device surgery with interruption of warfarin forgoing post-operative bridging therapy in patients with moderate or high thromboembolic risks.

Thromb J 2021 Apr 29;19(1):28. Epub 2021 Apr 29.

Cardiac Medical Unit, Grantham Hospital, 125 Wong Chuk Hang Road, Hong Kong SAR, China.

Background: For patients taking warfarin and undergoing pacemaker or implantable cardioverter-defibrillator surgery, clinical evidence and guidelines support continuation of warfarin therapy, as opposed to interruption of warfarin therapy with heparin bridging. Interruption of warfarin without post-operative bridging therapy may be a feasible alternative but data is sparse.

Methods: This is a single-arm observational study including adults who had interruption of warfarin therapy without post-operative bridging therapy for cardiac implantable electronic device (CIED) surgery performed between 2010 and 2019 in a tertiary referral hospital. Read More
