Geriatric Nutritional Risk Index and the Prognosis of Patients with Stroke: A Meta-Analysis.

Malnutrition evidenced by low geriatric nutritional risk index (GNRI) has been suggested as a potential predictor of poor prognosis of patients with various clinical conditions. We performed a meta-analysis to systematically assess the association between GNRI and the prognosis of patients after stroke. Cohort studies were identified by search of PubMed, Embase, Cochrane's Library and Web of Science databases from inception to March 25, 2022, according to the aim of the meta-analysis. A random-effect model incorporating the potential between-study heterogeneity was used to pool the results. Eight cohort studies with 13573 patients with stroke contributed to the meta-analysis. Pooled results showed that malnutrition as evidenced by low GNRI was independently associated with a higher risk of poor functional outcome [risk ratio (RR): 1.54, 95% confidence interval (CI): 1.19 to 1.98, p<0.001; I2=69%] and an increased incidence of all-cause mortality (RR: 1.82, 95% CI: 1.35 to 2.47, p<0.001; I2=74%). Sensitivity analyses showed consistent results in patients with ischemic stroke, and in prospective cohort studies. Subgroup analyses showed that the associations were not significant for patients with GNRI-defined mild malnutrition (p=0.18 and 0.20 for functional and mortality outcomes, respectively), but significant for patients with moderate-severe malnutrition (both p<0.001). Difference in follow-up durations did not significantly affect the associations (p for subgroup difference=0.75 and 0.70, respectively). In conclusion, a low GNRI is associated with poor functional and survival outcomes in patients after stroke.

Myelin oligodendrocyte glycoprotein-associated transverse myelitis after SARS-CoV-2 infection: A case report.

BACKGROUND: Cases of myelin oligodendrocyte glycoprotein (MOG) antibody-related disease have a history of coronavirus disease 2019 infection or its vaccination before disease onset. Severe acute respiratory syndrome virus 2 (SARS-CoV-2) infection has been considered to be a trigger of central nervous system autoimmune diseases. CASE SUMMARY: Here we report a 20-year male with MOG-associated transverse myelitis after a SARS-CoV-2 infection. The patient received a near-complete recovery after standard immunological treatments. CONCLUSION: Attention should be paid to the evaluation of typical or atypical neurological symptoms that may be triggered by SARS-CoV-2 infection.

Evaluation of efficacy and safety of Reteplase and Alteplase in the treatment of hyper-acute cerebral infarction.

Objective: The present study aimed to investigate the efficacy and safety of Reteplase (rPA) and Alteplase (rt-PA) in the treatment of hyper-acute cerebral infarction (CI).Methods: Six hundred and eleven patients with hyper-acute CI selected from September 2014 to September 2016 were assigned into the aspirin, rt-PA, rPA, rt-PA + aspirin, and rPA + aspirin groups based on their willingness. The difference of efficacy in five groups were evaluated with National Institute of Health Stroke Scale (NIHSS), modified rankin scale (mRS), and Barthel Index (BI). Coagulation function, blood lipid, and hemodynamics were analyzed. The safety differences were compared by observing the adverse reactions.Results: Compared with the rt-PA, rPA, and aspirin groups, NIHSS score, mRS score, the incidence of non- and symptomatic cerebral hemorrhage as well as the rate of adverse reactions were decreased, while BI were increased in the rt-PA + aspirin and rPA + aspirin groups after treatment. Compared with the rt-PA and rPA groups, total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) levels were lower, whereas the hematocrit, whole blood high shear viscosity, whole blood low shear viscosity, plasma viscosity, erythrocyte electrophoresis time, fibrinogen, erythrocyte sedimentation rate (ESR), K value in blood sedimentation equation, and the comprehensive abnormality degree of blood rheology were higher in the rt-PA + aspirin and rPA + aspirin groups.Conclusion: The efficacy and safety of rt-PA or rPA combined with aspirin in the treatment of hyper-acute CI were better than those of rPA or rt-PA monotherapy.
