Objective:The objectives of this study were to measure the global impact of the pandemic on the volumes for intravenous thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with two control 4-month periods.Methods:We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes and/or classifications in stroke databases.Results:There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95%CI, -11.7 to - 11.3, p<0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95%CI, -13.8 to -12.7, p<0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95%CI, -13.7 to -10.3, p=0.001). Recovery of stroke hospitalization volume (9.5%, 95%CI 9.2-9.8, p<0.0001) was noted over the two later (May, June) versus the two earlier (March, April) pandemic months. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. SARS-CoV-2 infection was noted in 3.3% (1,722/52,026) of all stroke admissions.Conclusions:The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months.
Current management guidelines for refractory status epilepticus (RSE) recommend the use of intravenous continuous anesthetic therapy, but there is little evidence to guide the selection of the most efficacious and safest drug. We conducted a retrospective study to evaluate the efficacy and safety of midazolam versus thiopental for treatment of RSE. Retrospective case-control series of prospectively identified patients treated with midazolam or thiopental for RSE between January 2007 and December 2014. The primary outcome was control of RSE. Secondary outcomes included the rate of adverse events, intensive care unit (ICU) and hospital length of stay, hospital mortality and long-term neurological outcome, assessed with the extended Glasgow outcome scale (GOS-E) at discharge and at six 6 months. A total of 33 patients were included, 19 treated with midazolam and 14 with thiopental. Groups were similar for demographic data, clinical variables, comorbidity and the underlying cause of RSE. The rate of control of SE did not differ between groups (63 vs. 64 %). Adverse events including hypotension (mean arterial pressure <70 mmHg) requiring vasopressors, infections, anemia requiring red blood cells transfusion, leucopenia (<4000/mm(3)), and hyponatremia (<130 mEq/l) were more frequent during thiopental infusion. Furthermore, patients treated with midazolam had a shorter median ICU length of stay (6 vs. 15 days; p = 0.02) and better GOS-E at 6 months (8 [8] vs. 4 [4, 5]; p = 0.01). These findings suggest that continuous midazolam administration is as efficacious as thiopental infusion for the treatment of RSE; however, midazolam was associated with a significantly lower number of adverse events. These findings should be confirmed in larger multicenter trials.
Whereas chronic mild-to-moderate hyponatremia has no impact on muscle strength, we demonstrate for the first time an impact of profound hyponatremia on nerve conduction studies. Further studies are needed to ascertain the contribution of these latter results on gait disturbances, propensity to falls and attention deficits associated with hyponatremia.
