Fluoxetine or Venlafaxine for Early Post Stroke Depression.

Context: Post stroke depression (PSD) is an under diagnosed morbidity of stroke and can negatively affect the prognosis of the patient. Aims: We intended to study the prevalence of PSD and the commonly used anti-depressants and their outcome in patients with PSD. Settings and Design: A prospective observational study was conducted in the patients admitted to the stroke unit of a tertiary care centre. Methods and Materials: Diagnosis of post stroke depression was made by the Hamilton Depression Rating Scale (HDRS) during the two-week period after stroke or in the clinic follow up. A comparison of clinical outcome and adverse events of the two anti-depressants used, i.e. venlafaxine and fluoxetine were done by a follow up of up to 6 months. Statistical Analysis Used: Independent sample test was used for statistical purposes in the study. Results: Out of the 326 stroke patients admitted in the department, 73 had PSD and 60 patients out of this were assigned into the study. Forty patients were males, and the mean age of the sample population was found to be 62.13 ± 11.14. Major risk factors identified were hypertension, diabetes mellitus, and dyslipidemia. Venlafaxine showed better outcome and less adverse events compared to fluoxetine. Major adverse events observed were hyponatremia, headache, insomnia, and anxiety. Conclusions: PSD in the early phase affects a substantial number of the stroke patients. Venlafaxine has got a better outcome and adverse event profile compared to fluoxetine in this group of patients. However, larger multicenter studies will provide more helpful data in this area.

Clinical Features and Outcome of Stroke with COVID-19. COVID-19 Stroke Study Group (CSSG), India.

BACKGROUND AND PURPOSE: Occurrence of stroke has been reported among patients with COVID-19. The present study compares clinical features and outcomes of stroke patients with and without COVID-19. METHODS: The COVID-19 Stroke Study Group (CSSG) is a multicentric study in 18 sites across India to observe and compare the clinical characteristics of patients with stroke admitted during the current pandemic period and a similar epoch in 2019. The present study reports patients of stroke with and without COVID-19 (CoVS and non-CoVS, respectively) seen between February 2020 and July 2020. Demographic, clinical, treatment, and outcome details of patients were collected. RESULTS: The mean age and gender were comparable between the two groups. CoVS patients had higher stroke severity and extent of cerebral involvement on imaging. In-hospital complications and death were higher among CoVS patients (53.06% vs. 17.51%; P < 0.001) and (42.31% vs. 7.6%; P < 0.001), respectively. At 3 months, higher mortality was observed among CoVS patients (67.65% vs. 13.43%; P < 0.001) and good outcome (modified Rankin score [mRS]: 0-2) was seen more often in non-CoVS patients (68.86% vs. 33.33%; P < 0.001). The presence of COVID-19 and baseline stroke severity were independent predictors of mortality. CONCLUSIONS: CoVS is associated with higher severity, poor outcome, and increased mortality. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and baseline stroke severity are independent predictors of mortality.

A Combined Arterial and Venous Grading Scale to Predict Outcome in Anterior Circulation Ischemic Stroke.

OBJECTIVE: Prognostic evaluation based on cortical vein score difference in stroke (PRECISE) score, a novel venous grading scale better predicted stroke outcomes. Henceforth, we aimed to describe and determine if a physiologically relevant combined arterial and venous grading scale (CRISP grading scale) is accurate in determining 90-day stroke outcomes in patients with proximal arterial occlusion in the anterior circulation. METHODS: Data are from the Keimyung Stroke Registry. Consecutive patients with M1 middle cerebral artery (MCA) or terminal internal carotid artery (ICA) occlusion on CT-angiography (CTA) from May-2004 to July-2008 were included. The affected hemisphere 'four veins composite score' and 'arterial collaterals' were each graded 'good' and 'poor'. On the combined scale, a 'good' grade represented a 'good' score on both scales and a 'poor' grade represented a 'poor' score on both scales. The 'other two' combinations were graded 'intermediate.' RESULTS: Eighty-one patients were included in the study. Dummy variable regression analysis demonstrated that poor outcome was commonly seen in the group with poor arterial and venous grades [OR(95%CI); 48 (8.24, 279.598); P < 0.00001] as opposed to poor arterial collaterals alone [OR(95%CI); 9.6(1.483,62.162); P = 0.018]. In multivariate analysis the CRISP grade [OR(95%CI); 2.638(1.192, 6.039), P = 0.017] and National Institutes of Health Stroke Scale [OR(95%CI);1.230(1.085, 1.395),P = 0.001(per unit increase)] emerged as the independent predictors of poor outcome (modified Rankin Scale >2) when adjusted for other imaging predictors of outcome. CONCLUSION: CRISP grading was precise in predicting stroke outcomes when compared to individual imaging scales including arterial collateral grading, PRECISE score and CTA-SI ASPECTS in patients with proximal arterial occlusion in the anterior circulation.
