1The ReaxFF reactive force-field: development, applications and future directions显示文摘The reactive force-field(ReaxFF)interatomic potential is a powerful computational tool for exploring,developing and optimizing material properties.Methods based on the principles of quantum mechanics(QM),while offering valuable theoretical guidance at the electronic level,are often too computationally intense for simulations that consider the full dynamic evolution of a system.Alternatively,empirical interatomic potentials that are based on classical principles require significantly fewer computational resources,which enables simulations to better describe dynamic processes over longer timeframes and on larger scales.Such methods,however,typically require a predefined connectivity between atoms,precluding simulations that involve reactive events.The ReaxFF method was developed to help bridge this gap.Approaching the gap from the classical side,ReaxFF casts the empirical interatomic potential within a bond-order formalism,thus implicitly describing chemical bonding without expensive QM calculations.This article provides an overview of the development,application,and future directions of the ReaxFF method.Thomas P Senftle Sungwook Hong Md Mahbubul Islam Sudhir B Kylasa Yuanxia Zheng Yun Kyung Shin Chad Junkermeier Roman Engel-Herbert Michael J Janik Hasan Metin Aktulga Toon Verstraelen Ananth Grama Adri CT van Duin 2016npj Computational Materials2016,,1:22
2Prenatal diagnosis and assessment of congenital spinal anomalies: Review for prenatal counseling显示文摘The last two decades have seen continuous advances in prenatal ultrasonography and in utero magnetic resonance imaging. These technologies have increasingly enabled the identification of various spinal pathologies during early stages of gestation. The purpose of this paper is to review the range of fetal spine anomalies and their management, with the goal of improving the clinician's ability to counsel expectant parents prenatally.Vidyadhar V Upasani Pamela Deaver Ketwaroo Judy A Estroff Benjamin C Warf John B Emans Michael P Glotzbecker 2016World Journal of Orthopedics2016,7,7:4
3New oral pharmacotherapeutic agents for venous thromboprophylaxis after total hip arthroplasty显示文摘Patients undergoing total hip arthroplasty(THA)are at high risk for developing venous thromboembolism and,therefore,require short term prophylaxis with antithrombotic agents.Recently,target specific oral anticoagulants(TSOA)including the direct thrombin inhibitor,dabigatran,and the factorⅩa inhibitors rivaroxaban,apixaban,and edoxaban have been approved for THA thrombopropylaxis in various countries.The TSOAs provide a rapid acting,oral alternative to parenteral agents including low-molecular weight heparins(LMWH)and fondaparinux;and compared to warfarin,they do not require routine laboratory monitoring and possess much fewer drug-drug interactions.Based on phaseⅢclinical studies,TSOAs have established themselvesas an effective and safe option for thromboprophylaxis after THA compared to LMWH,particularly enoxaparin,but require additional evaluation in specific populations such as the renally impaired or elderly.The ability to monitor and reverse these TSOAs in the case of bleeding complications or suspected sub-or supra-therapeutic anticoagulation is of importance,but remains investigational.This review will focus on the drug-specific characteristics,efficacy,safety,and economic impact of the TSOAs for thromboprophylaxis following THA,as well as the aspects of therapeutic monitoring and anticoagulation reversal in the event of bleeding complications or a need for urgent reversal.Garrett B Aikens Jacob R Osmundson Michael P Rivey 2014World Journal of Orthopedics2014,5,3:3
4Pediatric Nd:YAG laser capsulotomy in the operating room: review of 87 cases显示文摘AIM: To report a large series of children having Nd:YAG laser capsulotomy in the operating room using the lateral decubitus position. METHODS: Medical records of children who underwent Nd:YAG laser capsulotomy in the operating room at Ann & Robert H. Lurie Children's Hospital of Chicago between September 2008 and April 2017 were reviewed. Induction of general anesthesia and intubation was performed in the supine position after which the patient was placed in lateral decubitus position. The Nd:YAG laser capsulotomy was performed using a standard protocol. At the completion of the procedure, the patient was turned back into the supine position and extubated. RESULTS: This study included 87 eyes of 60 patients. Patient's age ranged from 1 to 18 y(mean 6.4±4.1 y). In most cases(84/87, 97%), the procedure was performed under general anesthesia. In all cases, good focus on the membrane was achieved, and the procedure was performed successfully. There were no intraoperative ocular or anesthesia-related complications. CONCLUSION: When performing Nd:YAG laser capsulotomy in the operating room, the lateral decubitus position allowsan easy and safe approach without the risk of potentially devastating complications that have been associated with the previously described sitting and prone positions.Michael Kinori Narasimhan Jagannathan Anne M Langguth Marjorie A Sasso Marilyn B Mets Bahram Rahmani Hawke Yoon Rebecca Mets-Halgrimson Sudhi P Kurup Janice L Zeid 2019International Journal of Ophthalmology(English edition)2019,12,5:2
5C-reactive protein and radiographic findings of lower respiratory tract infection in infants显示文摘AIM To evaluate the association between C-reactive protein(CRP) and radiological evidence of lower respiratory tract infection(LRTI) in infants.METHODS All patients aged less than 4 years who presented with suspected lower respiratory tract infection,who received a peri-presentation chest radiograph and CRP blood measurement over an 18-mo period were included in the study.Age,gender,source of referral,CRP,white cell count,neutrophil count along with the patients' symptoms and radiologist's report were recorded.RESULTS Three hundred and eleven patients met the inclusioncriteria.Abnormal chest radiographs were more common in patients with elevated CRP levels(P < 0.01).Radiologic signs of LRTI were identified in 73.7% of chest radiographs when a patient had a CRP level between 50-99 mg/L.CRP levels were a better predictor of positive chest radiograph findings for those aged greater than I year compared to those 1 year or less.CONCLUSION CRP may be used in patients with suspected LRTI diagnosis to select those who are likely to have positive findings on chest radiograph,thus reducing unnecessary chest radiographs.Maria Twomey Hannah Fleming Fiachra Moloney Kevin P Murphy Lee Crush Siobhan B O’Neill Oisin Flanagan Karl James Conor Bogue Owen J O’Connor Michael M Maher 2017World Journal of Radiology2017,9,4:2
