Background: Modified Nutrition Risk in the Critically Ill (m-NUTRIC) score is used to evaluate the nutritional risk of patients in intensive care units (ICUs). This study aimed to investigate whether m-NUTRIC can be used as a predictive factor related to the outcome of patients in surgical ICU (SICU) and to identify which patients will benefit from aggressive nutritional intervention according to the results of m-NUTRIC score. Methods: A total of 205 patients who were admitted to surgical ICU (SICU) with ventilator use for more than 24 hours were enrolled. The m-NUTRIC score data were calculated the day when the patients were admitted to SICU. Patients were divided into two groups according to their m-NUTRIC score: the low-risk group (<5 points, 116 patients) and the high risk group (≥5 points, 89 patients). Results: In this study, a total of 205 patients were enrolled for analysis, including patients in the low-risk group (n = 116) and those in the high risk group (n = 89). The mean duration of ventilator use was 3.6 ± 6.5 days, and average SICU stays for all patients was 5.1 ± 7.4 days. The SICU mortality was significantly higher in the high-risk group (10.3% vs 1.7%). Comparison between survivals and nonsurvivals was carried out, and the data showed that the AKI, Vasopressors, SOFA, APACHE-II, m-NUTRIC score, and shock patient were all significantly associated with higher mortality. The multivariate analysis revealed that acute kidney injury (OR = 13.16; 95% confidence intervals = 3.69–46.92; p < 0.0001) and m-NUTRIC score were independent factors of ICU mortality in these patients. A receiver operating characteristic curve was used to calculate the area under the curve, which was 0.801. The data indicated that high m-NUTRIC score were significantly associated with SICU mortality with the cutoff score > 4 (sensitivity = 90.5%, specificity = 62.3%, p < 0.001). Conclusion: We found in this study that the high m-NUTRIC score is an independent factor of ICU mortality, and m-NUTRIC score can be used as an initial screening tool for nutritional assessment in patients admitted to surgical ICU. Further investigations to evaluate whether the aggressive nutritional intervention would be beneficial in the SICU patients with higher m-NUTRIC score is mandatory.

Background: Tentorial dural arteriovenous fistula is a rare subtype of intracranial dural arteriovenous fistula (DAVF) with a deteriorating natural course, which may be attributed to its pial angioarchitecture. TDAVF often harbors feeders arising from pial arteries (FPAs). Reports have revealed that, if these feeders are not obliterated early, the restricted venous outflow during the embolization process may cause upstream congestion in the fragile pial network, which increases the risk of hemorrhagic complications. Because most reported cases of TDAVF were embolized through feeders from non-pial arteries (FNPAs), little is known of the feasibility of direct embolization through FPAs.Methods: We present three patients with medial TDAVFs that were embolized through the dural branches of the posterior cerebral and superior cerebellar arteries. Findings from brain magnetic resonance imaging, computed tomography, angiography, and clinical outcomes are described. Furthermore, we performed a review of the literature on TDAVFs with FPAs.Results: The fistulas were completely obliterated in two patients; both recovered well with no procedure-related complications. The fistula was nearly obliterated in one patient, who developed left superior cerebellum and midbrain infarct due to the reflux of the embolizer into the left superior cerebellar artery. Including our cases, eight cases of TDAVFs with direct embolization through the FPAs have been reported, and ischemic complications occurred in three (37.5%).Conclusions: Advancing microcatheter tips as close to the fistula point as possible and remaining highly aware of potential embolizer flow back into the pial artery are key factors in achieving successful embolization. Balloon-assisted embolization may be an option for treating TDAVFs with FPAs in the future.

The authors reported the clinical course of a 58-year-old female suffering from cerebral venous sinus thrombosis associated with hemorrhage after the ChAdOx1 nCov-19 vaccination. Emergent decompressive craniectomy was performed, and aggressive blood transfusion was given. Nevertheless, progressive intracerebral hemorrhage and thrombocytopenia developed. A delayed diagnosis was made on a rare complication of vaccine-induced immune thrombotic thrombocytopenia (VITT) with a positive result of anti-platelet factor 4 antibodies (PF4 Ab). The patient died 4 days postoperative due to brainstem failure.
