Cerebral microbleeds are associated with an increased risk of hemorrhagic transformation (HT) following acute ischemic stroke. We investigated whether the effect of dabigatran (vs. aspirin) in patients with acute minor non-cardioembolic ischemic stroke/transient ischemic attack (TIA) is modified by baseline microbleeds on MRI.

The Dabigatran Treatment of Acute Stroke II trial randomized 305 patients with acute minor non-cardioembolic ischemic stroke/TIA to dabigatran (150/110 mg twice daily) or aspirin (81 mg daily) for 30 days. Microbleeds were centrally adjudicated in patients with an interpretable blood-sensitive sequence on baseline MRI. In this post hoc analysis, we used multivariable regression models to determine the association between microbleeds and any incident HT on day-30 MRI and excellent functional outcome (modified Rankin scale = 0–1) at 90 days.

A total of 251 (82.3%) participants (mean age = 66 ± 13 years, 36% women, median [IQR] onset-to-randomization time = 40[27–55] hours; median [IQR] NIHSS = 1 [0–2]) were included, of whom 82 (33%) had microbleeds. On day-30 MRI, 6% (n = 14) developed HT, and 80% (n = 191) achieved 90-day mRS of 0–1. We found no association between microbleed presence and HT (adjusted OR = 0.84; 95%CI:0.21–3.25) or excellent functional outcome (adjusted RR = 1.09; 95%CI:0.94–1.26). The rate of HT in patients with microbleeds was 3% with dabigatran and 4% with aspirin (OR = 0.85; 95%CI:0.11–6.75). Excellent functional outcome occurred in 74% and 84% of dabigatran and aspirin-treated patients, respectively (RR = 0.88; 95%CI:0.69–1.12). The presence, severity or location of microbleeds did not modify the effect of dabigatran on these outcomes (p-interaction > 0.05).

Early dabigatran treatment appears safe in patients with acute minor non-cardioembolic ischemic stroke/TIA and hemorrhage-prone cerebral small vessel disease marked by microbleeds on MRI.

Dying is mostly seen as a dreadful event, never a happy experience. Yet, as palliative care physicians, we have seen so many patients who remained happy despite facing death. Hence, we conducted this qualitative study to explore happiness in palliative care patients at the University of Malaya Medical Centre.

Twenty terminally ill patients were interviewed with semi-structured questions. The results were thematically analyzed.

Eight themes were generated: the meaning of happiness, connections, mindset, pleasure, health, faith, wealth, and work. Our results showed that happiness is possible at the end of life. Happiness can coexist with pain and suffering. Social connections were the most important element of happiness at the end of life. Wealth and work were given the least emphasis. From the descriptions of our patients, we recognized a tendency for the degree of importance to shift from the hedonic happiness to eudaimonic happiness as patients experienced a terminal illness.

To increase the happiness of palliative care patients, it is crucial to assess the meaning of happiness for each patient and the degree of importance for each happiness domain to allow targeted interventions.

We investigated the impact of regionally imposed social and healthcare restrictions due to coronavirus disease 2019 (COVID-19) to the time metrics in the management of acute ischemic stroke patients admitted at the regional stroke referral site for Central South Ontario, Canada.

We compared relevant time metrics between patients with acute ischemic stroke receiving intravenous tissue plasminogen activator (tPA) and/or endovascular thrombectomy (EVT) before and after the declared restrictions and state of emergency imposed in our region (March 17, 2020).

We identified a significant increase in the median door-to-CT times for patients receiving intravenous tPA (19 min, interquartile range (IQR): 14–27 min vs. 13 min, IQR: 9–17 min, p = 0.008) and/or EVT (20 min, IQR: 15–33 min vs. 11 min, IQR: 5–20 min, p = 0.035) after the start of social and healthcare restrictions in our region compared to the previous 12 months. For patients receiving intravenous tPA treatment, we also found a significant increase (p = 0.005) in the median door-to-needle time (61 min, IQR: 46–72 min vs. 37 min, IQR: 30–50 min). No delays in the time from symptom onset to hospital presentation were uncovered for patients receiving tPA and/or endovascular reperfusion treatments in the first 1.5 months after the establishment of regional and institutional restrictions due to the COVID-19 pandemic.

We detected an increase in our institutional time to treatment metrics for acute ischemic stroke patients receiving tPA and/or endovascular reperfusion therapies, related to delays from hospital presentation to the acquisition of cranial CT imaging for both tPA- and EVT-treated patients, and an added delay to treatment with tPA.

The optimal timing of anticoagulation after ischemic stroke in atrial fibrillation (AF) patients is unknown. Our aim was to demonstrate the feasibility and safety of initiating dabigatran therapy within 14 days of transient ischemic attack (TIA) or minor stroke in AF patients.

A prospective, multi-center registry (NCT02415855) in patients with AF treated with dabigatran within 14 days of acute ischemic stroke/TIA (National Institutes of Health Stroke Scale (NIHSS) ≤ 3) onset. Baseline and follow-up computed tomography (CT) scans were assessed for hemorrhagic transformation (HT) and graded by using European Cooperative Acute Stroke Study criteria.

One hundred and one patients, with a mean age of 72.4 ± 11.5 years, were enrolled. Median infarct volume was 0 ml. Median time from index event onset to dabigatran initiation was 2 days, and median baseline NIHSS was 1. Pre-treatment HT was present in seven patients. No patients developed symptomatic HT. On the day 7 CT scan, HT was present in six patients (one progressing from baseline hemorrhagic infarction type 1). Infarct volume was a predictor of incident HT (odds ratio = 1.063 [1.020–1.107], p < 0.003). All six (100%) patients with new/progressive HT were functionally independent (modified Rankin Scale (mRS) = 0–2) at 30 days, which was similar to those without HT (90%, p = 0.422). Recurrent ischemic events occurred within 30 days in four patients, two of which were associated with severe disability and death (mRS 5 and 6, respectively).

Early dabigatran treatment did not precipitate symptomatic HT after minor stroke. Asymptomatic HT was associated with larger baseline infarct volumes. Early recurrent ischemic events may be clinically more important.
