Objective: A meta-analysis of randomized controlled trials was conducted to assess efficacy and safety of bilateral ultrasound-guided erector spinae plane block (ESPB) for postoperative analgesia in patients receiving spine surgery., Methods: PubMed, Embase, and CENTRAL databases were searched by 2 reviewers independently to identify randomized controlled trials evaluating the efficacy of ultrasound-guided ESPB for pain management in patients undergoing spine surgery. For meta-analysis, mean difference (MD) and 95% confidence interval (CI) were selected for continuous data, and risk ratio (RR) and 95% CI were selected for dichotomous variables., Results: A total of 25 randomized controlled trials including 1917 patients (873 in ESPB group and 874 in control group) were eligible for inclusion. At rest, ESPB was associated with significantly lower pain intensity at 0, 2, 4, 6, 8, 12, 24, and 48 hours compared with the control group. During movement, ESPB was associated with significantly lower pain intensity at 0, 4, 6, 8, 12, 24, and 48 hours compared with the control group. Significantly reduced opioid consumption (MD = -6.29, 95% CI [-8.16, 4.41], P < 0.001), prolonged time for first rescue analgesia (MD = 7.51, 95% CI [3.47, 11.54], P < 0.001), fewer patients needing rescue analgesia (RR = 0.34, 95% CI [0.28, 0.43], P < 0.0001), improved patient satisfaction (MD = 1.34, 95% CI [0.88, 1.80], P < 0.001), and shorter length of hospital stay (MD = -0.38, [95% CI -0.50, -0.26], P < 0.001) were demonstrated after use of ESPB. Additionally, ESPB was associated with decreased risks of any adverse event (RR = 0.51, 95% CI [0.43, 0.60], P < 0.001) and postoperative nausea and vomiting events (RR = 0.39, 95% CI [0.31, 0.49], P < 0.001)., Conclusions: Ultrasound-guided ESPB is an effective adjunctive technique with good tolerability for multimodal analgesia in management of pain in patients undergoing spine surgery., (Copyright © 2023 Elsevier Inc.

Objective: To critically evaluate the efficacy and safety of early versus delayed anterior cruciate ligament reconstruction (ACLR) for anterior cruciate ligament (ACL) injuries based on the different cut-off values of the timing of operation., Methods: PubMed, Medline, Embase, Cochrane library, China National Knowledge Infrastructure, Chinese Biomedical Literature, and Wanfang Digital Periodical database were searched from inception to November 2022 without language restrictions. Randomized controlled trials (RCTs) and cohort studies (CSs) comparing early ACLR with delayed ACLR for ACL injuries were included., Results: Twenty-four studies (10 RCTs and 14 CSs) were included. According to the information from included studies, 3 weeks, 4 weeks, 6 weeks, 6 months, and 12 months after ACL injuries were considered as the cut-off values of early and delayed ACLR. When 4 weeks were considered as the cut-off value, early ACLR could significantly improve Lysholm score, IKDC score and VAS score at 6 and 12 months postoperatively and decrease the incidence of adverse events compared with delayed ACLR (P < 0.05). However, no statistically significant difference in positive rate of Lachman test and incidence of meniscus injuries and chondral lesions between the two groups when 3 weeks, 6 weeks, 6 months or 12 months after ACL injuries were considered as the cut-off values of early and delayed ACLR (P > 0.05)., Conclusion: The present study suggests that early ACLR, especially conducted within 3-4 weeks after ACL injuries, may be more effective for improving knee function and relieving pain compared with delayed ACLR. More high-quality RCTs are warranted., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Ai-Feng Liu reports financial support was provided by National Natural Science Foundation of China.

Objective: This study focused on the prediction factors of catastrophic outcomes of all-cause mortality at 90 days after mechanical thrombectomy and selection of candidates for clinical decision making up by the generating pre-MT and peri-MT prognostic models., Method: A secondary analysis based on the prospective, multicenter, randomized, non-inferiority clinical trial of Jrecan retriever from China were performed in this study. 187 stroke patients with a large-vessel anterior circulation occlusion, NIHSS score ≥ 6, ASPECT ≥ 7, and stroke onset time within 8 h were enrolled from March 1, 2018 to June 30, 2019 and followed up for 90 days. Data with mRS cumulative rates of 6, as well as mortality were analyzed and potential predictors for the mortality risk were identified by univariate and multivariate regression analysis., Results: Among 186 patients, the median age was 66 years (IQR, 58-74) and 106 patients (56.4%) were male. The mortality was 20.8% (39/186) and general favorable outcome was obtained in 78 patients (41.7%, 78/187) at 90 days after MT. Five variables including ASPECT≤ 9 (3.136 [1.239-7.939], P = 0.016), Occlusion location with IC-ICA (3.538 [1.604-7.803], P = 0.002), un-Successful recanalization; PH (7.644 [1.890-30.917], P = 0.004), and END (without PH) with a significance of P < 0.05 were entered into the multivariable logistic regression analysis and were incorporated into pre-procedure model and peri-procedure models respectively., Conclusions: Occlusion with IC-ICA and PH were the strong predictors for mortality risk at 90-day, which could be reduced through good management and evaluation during pre-procedure and peri-procedure of mechanical thrombectomy., Competing Interests: Conflicts of interest The authors declare that they have no competing interests., (Copyright © 2022 The Authors.

Objective: We critically evaluated the efficacy and safety of oblique lumbar interbody fusion (OLIF) versus transforaminal lumbar interbody fusion (TLIF) for degenerative lumbar spondylolisthesis (DLS)., Methods: PubMed, Embase, Cochrane Library, the Web of Science Core Collection, Chinese Biomedical Literature, China National Knowledge Infrastructure, Wanfang Digital Periodicals, and Chinese Science and Technology Periodicals were searched from their inception to February 2021. Randomized controlled trials and retrospective or prospective cohort studies (CSs) comparing OLIF and TLIF for DLS were included. A meta-analysis was conducted, if possible., Results: Ten studies were included in the statistical analysis. The pooled results of the CSs showed no statistically significant differences (P > 0.05) in pain relief at 3 or 6 months of follow-up and functional improvement at 1 or 3 months of follow-up in DLS patients between those who had undergone OLIF versus TLIF. The pooled results of the CSs showed that OLIF could significantly improve the degree of lumbar lordosis, foraminal height, and disc height and decrease the intraoperative blood loss, postoperative drainage volume, operative duration, bed rest time, and hospital length of stay (P < 0.05) compared with TLIF. The incidence of adverse events was not significantly different statistically between OLIF and TLIF., Conclusions: The results from the present study suggest that pain relief and functional improvement were not significantly different between OLIF and TLIF. Nevertheless, the use of OLIF might improve radiological outcomes and reduce intraoperative blood loss, postoperative drainage volume, operative duration, bed rest duration, and hospital length of stay compared with TLIF. Additional high-quality randomized controlled trials are still required to confirm these findings., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objectives: The optimal treatment of symptomatic non-acute atherosclerotic intracranial large artery occlusion (ILAO) beyond 24 h from onset remains uncertain. We investigate the outcomes of late endovascular recanalization for symptomatic non-acute atherosclerotic ILAO., Patients and Methods: From September 2013 to July 2018, with safety as the first principle, late endovascular recanalization for symptomatic non-acute atherosclerotic ILAO beyond 24 h from onset was attempted in 32 consecutive patients. Primary safety outcome was any stroke or death within 30 days. Primary efficacy outcome were functional independence at 90 days., Results: The median time from imaging-documented occlusion to treatment was 25.5 days (interquartile range: 10.5-36.5) for all patients. Technical success in recanalization was achieved in 17 patients (53.1%, 17/32). The 30-day rate of any stroke or death was 5.9% (1/17) in the recanalized group versus 6.7% (1/15) in the failure group (P = 0.927). The rate of functional independence at 90 days (70.5%, 12/17) was increased significantly as compared with that before operation (23.5%, 4/17) in the recanalized group (P = 0.015). The rate of functional independence at 90 days (66.7%, 10/15) was not different from that before operation (66.7%,10/15) in the failure group (P = 1.00). The median score reduction in mRS from baseline at 90 days was 1.0 (interquartile range: 1.0-2.0) in the recanalized group versus 0 (interquartile range: 0.0-0.0) in the failure group (P＜0.001)., Conclusion: For carefully selected patients with symptomatic non-acute atherosclerotic ILAO beyond 24 h from onset, late endovascular recanalization is technically feasible. The periprocedural safety of late endovascular recanalization is acceptable. Successful recanalization may effectively improve the degree of disability in such patients. However, it should be emphasized that revascularization of non-acute ILAO is a high risk procedure, which should only be performed by experienced operators with safety as the first principle., (Copyright © 2019 Elsevier B.V.

Sensitive detection of tetrabromobisphenol A (TBBPA) and its derivatives, a group of emerging toxic contaminants, is highly necessitated in environmental investigation. Herein a novel analytical strategy based on reactive extractive electrospray ionization (EESI) tandem mass spectrometry for detection of tetrabromobisphenol A bis(2-hydroxyethyl ether) (TBBPA-BHEE), tetrabromobisphenol A bis(glycidyl ether) (TBBPA-BGE), tetrabromobisphenol A bis(allylether) (TBBPA-BAE), and tetrabromobisphenol S bis(allylether) (TBBPS-BAE) in industrial waste water samples was developed. Active silver cations (Ag(+)), generated by electrospraying a silver nitrate methanol solution (10 mg L(-1)), collides the neutral TBBPA derivatives molecules in the EESI source to form [M+Ag](+) complexes of the analytes under the ambient conditions. Upon collision-induced dissociation (CID), characteristic fragments of the [M+Ag](+) complexes were identified for confident and sensitive detection of the four TBBPA derivatives. Under the optimized experimental conditions, the instrumental limits of detection (LODs) of TBBPA-BHEE, TBBPA-BGE, TBBPA-BAE and TBBPS-BAE were 0.37, 0.050, 0.76, and 4.6 μg L(-1), respectively. The linear ranges extended to 1000 μg L(-1) (R(2)≥0.9919), and the relative standard deviations (RSDs), inter-day variation and intra-day variation were less than 7.8% (n=9), 10.0% (n=5), and 14.8% (n=1 per day for 5 days) for all derivatives. TBBPA derivative manufacturing industrial waste water, river water and tap water samples were fast analyzed with the proposed method. The contents of TBBPA derivatives were various in the collected samples, with the highest 19.9±0.3 μg L(-1) of TBBPA-BAE in the waste water samples., (Copyright © 2014 Elsevier B.V.
