Laparoscopic anterior lumbar interbody fusion (L-ALIF), which employs laparoscopic cameras to facilitate a less invasive approach, originally gained traction during the 1990s but has subsequently fallen out of favor. As the envelope for endoscopic approaches continues to be pushed, a recurrence of interest in laparoscopic and/or endoscopic anterior approaches seems possible. Therefore, evaluating the current evidence base in regard to this approach is of much clinical relevance. To this end, a systematic literature search was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using the following keywords: “(laparoscopic OR endoscopic) AND (anterior AND lumbar).” Out of the 441 articles retrieved, 22 were selected for quantitative analysis. The primary outcome of interest was the radiographic fusion rate. The secondary outcome was the incidence of perioperative complications. Meta-analysis was performed using RStudio’s “metafor” package. Of the 1,079 included patients (mean age, 41.8±2.9 years), 481 were males (44.6%). The most common indication for L-ALIF surgery was degenerative disk disease (reported by 18 studies, 81.8%). The mean follow-up duration was 18.8±11.2 months (range, 6–43 months). The pooled fusion rate was 78.9% (95% confidence interval [CI], 68.9–90.4). Complications occurred in 19.2% (95% CI, 13.4–27.4) of L-ALIF cases. Additionally, 7.2% (95% CI, 4.6–11.4) of patients required conversion from L-ALIF to open surgery. Although L-ALIF does not appear to be supported by studies available in the literature, it is important to consider the context from which these results have been obtained. Even if these results are taken at face value, the failure of endoscopy to have a role in the ALIF approach does not mean that it should not be incorporated in posterior approaches.

Resonances in QCD

Lutz, M.F.M.,Lange, J.S.,Pennington, M.,Bettoni, D.,Brambilla, N.,Crede, V.,Eidelman, S.,Gillitzer, A.,Gradl, W.,Lang, C.B.,Metag, V.,Nakano, T.,Nieves, J.,Neubert, S.,Oka, M.,Olsen, S.L.,Pappagallo, North Holland Pub. Co 2016 Nuclear physics. A Vol.948 No.-

<P>We report on the EMMI Rapid Reaction Task Force meeting 'Resonances in QCD', which took place at GSI October 12-14,2015. A group of 26 people met to discuss the physics of resonances in QCD. The aim of the meeting was defined by the following three key questions: What is needed to understand the physics of resonances in QCD? Where does QCD lead us to expect resonances with exotic quantum numbers? What experimental efforts are required to arrive at a coherent picture? For light mesons and baryons only those with up, down and strange quark content were considered. For heavy-light and heavy-heavy meson systems, those with charm quarks were the focus. This document summarizes the discussions by the participants, which in turn led to the coherent conclusions we present here. (C) 2016 Elsevier B.V. All rights reserved.</P>

Traumatic Spinal Injury Associated with All-Terrain Vehicle (ATV) Accidents: A 10-Year Retrospective Analysis of the Coachella Valley

Brian Fiani,Rebecca Houston,Alessandra Cathel,Elisabeth Pennington,Imran Siddiqi,Mohammad Arshad,Marisol Soula,Ryne Jenkins 대한신경손상학회 2021 Korean Journal of Neurotrauma Vol.17 No.2

Objective: The use of all-terrain vehicles (ATVs) and associated injuries have significantly increased in the last decade. This study aimed to determine the frequency of ATV-associated spinal cord injuries (SCIs) in the Coachella Valley, California, and provide recommendations for data reproducibility in other areas with a similarly substantial level of ATV usage and injuries. Methods: This retrospective analysis included data obtained through screening the trauma database of a level II trauma center for ATV-related injuries between January 1, 2010 and January 1, 2020. Results: Our data suggest that more than one-third of patients admitted to the trauma center over a 10-year period suffered from spinal injury. Injuries to the spine were further categorized as including the spinal cord (radiographically or clinically) or only including the bony or ligamentous elements of the spine. Injury was more common in men and predominantly located in the thoracic spine. Injuries such as epidural hematoma, vertebral artery, and cord contusion were common, with many patients requiring neurosurgical intervention. Conclusion: Highlighting the implicit dangers of ATV accidents on the spine could help identify outcomes and variables predictive of spinal injuries and spinal cord injuries necessary for patient management. Additionally, our study sets the framework by which legislating bodies could replicate the study for proper legislation and recommendations that may help prevent such injuries.

Spinal Robotics in Adult Spinal Deformity Surgery: A Systematic Review

Kareem Khalifeh,Nolan J. Brown,Zach Pennington 대한척추신경외과학회 2024 Neurospine Vol.21 No.1

Spinal robotics have the potential to improve the consistency of outcomes in adult spinal deformity (ASD) surgery. The objective of this paper is to assess the accuracy of pedicle and S2 alar-iliac (S2AI) screws placed with robotic guidance in ASD patients. PubMed Central, Google Scholar, and an institutional library database were queried until May 2023. Articles were included if they described ASD correction via robotic guidance and pedicle and/or S2AI screw accuracy. Articles were excluded if they described pediatric/adolescent spinal deformity or included outcomes for both ASD and non-ASD patients without separating the data. Methodological quality was assessed using the Newcastle-Ottawa scale. Primary endpoints were pedicle screw accuracy based on the Gertzbein-Robbins Scale and self-reported accuracy percentages for S2AI screws. Data were extracted for patient demographics, operative details, and perioperative outcomes and assessed using descriptive statistics. Five studies comprising 138 patients were included (mean age 66.0 years; 85 females). A total of 1,508 screws were inserted using robotic assistance (51 S2AI screws). Two studies assessing pedicle screws reported clinically acceptable trajectory rates of 98.7% and 96.0%, respectively. Another study reported a pedicle screw accuracy rate of 95.5%. Three studies reported 100% accuracy across 51 total S2AI screws. Eight total complications and 4 reoperations were reported. Current evidence supports the application of robotics in ASD surgery as safe and effective for placement of both screw types. However, due to the paucity of data, a comprehensive assessment of its incremental benefit over other techniques cannot be made. Further work using expanded cohorts is merited.

Guidelines for the next 10 years of proteomics

Wilkins, Marc R.,Appel, Ron D.,Van Eyk, Jennifer E.,Chung, Maxey C. M.,Gö,rg, Angelika,Hecker, Michael,Huber, Lukas A.,Langen, Hanno,Link, Andrew J.,Paik, Young-Ki,Patterson, Scott D.,Pennington, WILEY-VCH Verlag 2006 Proteomics Vol.6 No.1

<P>In the last ten years, the field of proteomics has expanded at a rapid rate. A range of exciting new technology has been developed and enthusiastically applied to an enormous variety of biological questions. However, the degree of stringency required in proteomic data generation and analysis appears to have been underestimated. As a result, there are likely to be numerous published findings that are of questionable quality, requiring further confirmation and/or validation. This manuscript outlines a number of key issues in proteomic research, including those associated with experimental design, differential display and biomarker discovery, protein identification and analytical incompleteness. In an effort to set a standard that reflects current thinking on the necessary and desirable characteristics of publishable manuscripts in the field, a minimal set of guidelines for proteomics research is then described. These guidelines will serve as a set of criteria which editors of PROTEOMICS will use for assessment of future submissions to the Journal.</P>
