Introduction: Mediterranean diet (MeDiet) has been associated with lower risk of stroke. Additionally, animal models suggested that some components of MeDiet are associated with better outcomes after ischemic stroke (IS). We aimed to evaluate the association between global adherence to the MeDiet and the consumption of particular components of the MeDiet with stroke outcomes. Material and Methods: Multicenter observational study of consecutive IS patients treated with endovascular therapy. Inclusion criteria were large anterior circulation vessel occlusion and pre-stroke modified Rankin scale (mRS) <2. Adherence to MeDiet prior to stroke was evaluated using MEDAS 14-item scale. We evaluated the total score and also individual components of the scale. Clinical, radiological, and prognostic variables were collected. Good functional prognosis was considered as mRS ≤2 and complete recanalization as thrombolysis in cerebral infarction 3. Results: From January 1 to October 30, 2018, 239 patients were included (mean age 71 years, 48% women, median baseline NIHSS 16). Median MEDAS scale was 8 points (7–10). Patients with a higher adherence to MeDiet had significantly lower total and LDL-cholesterol levels. Total adherence score was not associated with stroke outcomes. In multivariate analyses, consumption of olive oil as the principal source of fat was independently associated with good functional outcome at 3 months, OR 3.2 (1.1–10.1) and daily consumption of wine was independently associated with complete recanalization, OR 2.0 (1.1–3.8). Conclusions: Our study suggests that some components of MeDiet, such as olive oil and wine consumption, are related to better prognosis after stroke. More studies are needed to confirm these findings.

Background: Prealbumin is a marker of malnutrition and inflammation. It has been associated with poor prognosis in cardiovascular disease, but less is known in stroke patients. Our objective was to evaluate the association of prealbumin levels at admission with prognosis in patients with stroke treated with mechanical thrombectomy. Material & Methods: Retrospective study of a prospective database of consecutive patients treated with mechanical thrombectomy. Clinical, radiological and blood parameters including serum prealbumin, and prognostic variables such as respiratory infection, in-hospital mortality, and modified Rankin scale at 3 months were collected. Results: We included 319 patients between 2018-2019. Prealbumin levels were significantly lower in patients older than 80 years, women, patients with a prestroke Rankin score >2, glomerular filtrate rate <60 ml/min and in those with atrial fibrillation. Regarding prognostic variables, prealbumin levels were not associated with respiratory infection. Low prealbumin levels were associated with poor functional prognosis (Rankin score >2), in-hospital mortality and 3-month mortality. In multivariate analysis, prealbumin was an independent risk factor associated with mortality at 3 months, OR 0.92 [0.86-0.98], p = 0.019. Conclusion: Lower prealbumin levels at admission behaved as independent predictor of long-term mortality in patients treated with mechanical thrombectomy. These results should be replicated in other cohorts.
