ABSTRACT
Background and purpose:
Fibrinogen to albumin ratio (FAR) is thought to have a predictive effect in diseases such as cancer and myocardial infarction. We aimed to elucidate the prognostic value of FAR in ischemic stroke patients who underwent mechanical thrombectomy.
. Methods:A total of 103 patients hospitalized for acute stroke who underwent mechanical thrombectomy within 6 hours of symptoms’ outset have been analyzed retrospectively. Stroke severity was interpreted via the National Institutes of Health Stroke Scale (NIHSS) score during the neurological examination. Recanalization success after mechanical thrombectomy was evaluated with the TICI score (Thrombolysis in Cerebral Infarction scale), and 2b – 3 patients were recorded as those with recanalization. The patients’ modified Rankin scale (mRS) at discharge and at the end of the third month were recorded.
. Results:Statistically significant differences were observed in age, admission blood glucose, glomerular filtration rate and FAR according to the mRS scores of the patients in the third month (p<0.05). Significant variables in the risk factor analysis were re-evaluated in the multivariate model. The best model was determined using the backward Wald method in the multivariate model, and it was determined that differences in age, admission blood glucose, and FAR were significant.
. Conclusion:FAR can be used as a novel, effective, economical, and practical biomarker in patient with acute ischemic stroke who underwent mechanical thrombectomy.

Background@#Sciatic nerve injury due to intramuscular injection (SNIII) is still a health problem. This study aimed to determine whether there is a correlation between neuropathic pain and electrodiagnostic findings in SNIII. @*Methods@#Patients whose clinical and electrodiagnostic findings were compatible with SNIII participated in this retrospective cohort study. Compound muscle action potential (CMAP) and sensory nerve action potential (SNAP) amplitudes of the sural, superficial peroneal, peroneal, and tibial nerves were graded from 1 to 4. Leeds assessment of neuropathic symptoms and signs scale (LANSS) was applied to all patients. @*Results@#Forty-eight patients were included in the study, 67% of whom had a LANSSscore ≥ 12. Sural SNAP amplitude abnormalities were present in 8 (50%) out of 16patients with a LANSS score < 12, and 28 (87.5%) out of 32 patients with a LANSS score ≥ 12, with significant differences between the groups (P = 0.011). There was a positive correlation between the LANSS score and the sural SNAP amplitude grading (P = 0.001, r = 0.476). A similar positive correlation was also found in the LANSS score and the tibial nerve CMAP amplitude grading (P = 0.004, r = 0.410). @*Conclusions@#This study showed a positive correlation between the severity of tibial nerve CMAP/sural SNAP amplitude abnormality and LANSS score in SNIII. Neuropathic pain may be more common in SNIII patients with sural nerve SNAP amplitude abnormality.
