Stroke etiologies in patients with COVID-19: the SVIN COVID-19 multinational registry.

Background And Purpose: Coronavirus disease 2019 (COVID-19) is associated with a small but clinically significant risk of stroke, the cause of which is frequently cryptogenic. In a large multinational cohort of consecutive COVID-19 patients with stroke, we evaluated clinical predictors of cryptogenic stroke, short-term functional outcomes and in-hospital mortality among patients according to stroke etiology.

Methods: We explored clinical characteristics and short-term outcomes of consecutively evaluated patients 18 years of age or older with acute ischemic stroke (AIS) and laboratory-confirmed COVID-19 from 31 hospitals in 4 countries (3/1/20-6/16/20).

Mechanisms of action of cannabidiol in adoptively transferred experimental autoimmune encephalomyelitis.

Cannabidiol (CBD) is one of the most important compounds in Cannabis sativa, lacks psychotropic effects, and possesses a high number of therapeutic properties including the amelioration of experimental autoimmune encephalomyelitis (EAE). The aim of this study was to analyse the relative efficacy of CBD in adoptively transferred EAE (at-EAE), a model that allows better delineation of the effector phase of EAE. Splenocytes and lymph nodes from mice with actively induced EAE were cultured in the presence of MOG and IL-12 and inoculated intraperitoneally in recipient female C57BL/6J mice.

Comparative study of the quality of life between arthrodesis and total arthroplasty substitution of the ankle.

Our goal was to compare the health status of patients with primary and secondary arthrosis of the ankle before and after arthrodesis or total substitution arthroplasty, and to determine the improvement in quality of life and whether there is any difference between these techniques. A prospective comparative study of clinical-functional evaluation was performed using the American Orthopaedic Foot & Ankle Society (AOFAS) scale and quality of life with the short form (SF)-36 questionnaire in patients who underwent arthrodesis (16 cases) or total substitution arthroplasty of the ankle (14 cases) after 2 years (mean, 25.2 months) of follow-up after surgery, in comparison with the baseline preoperative status.
