| 1 | Accuracy of urea breath test in Helicobacter pylori infection: Meta-analysis显示文摘AIM: To quantitatively summarize and appraise the available evidence of urea breath test(UBT) use to diagnose Helicobacter pylori(H. pylori) infection in patients with dyspepsia and provide pooled diagnostic accuracy measures.METHODS: We searched MEDLINE, EMBASE, Cochrane library and other databases for studies addressing the value of UBT in the diagnosis of H. pylori infection. We included cross-sectional studies that evaluated the diagnostic accuracy of UBT in adult patients with dyspeptic symptoms. Risk of bias was assessed using QUADAS(Quality Assessment of Diagnostic Accuracy Studies)-2 tool. Diagnostic accuracy measures were pooled using the random-effects model. Subgroup analysis was conducted by UBT type(13C vs 14C) and by measurement technique(Infrared spectrometry vs Isotope Ratio Mass Spectrometry).RESULTS: Out of 1380 studies identified, only 23 met the eligibility criteria. Fourteen studies(61%) evaluated 13 C UBT and 9 studies(39%) evaluated 14 C UBT. There was significant variation in the type of reference standard tests used across studies.Pooled sensitivity was 0.96(95%CI: 0.95-0.97) andpooled specificity was 0.93(95%CI: 0.91-0.94). Likelihood ratio for a positive test was 12 and for a negative test was 0.05 with an area under thecurve of 0.985. Meta-analyses were associated with a significant statistical heterogeneity that remained unexplained after subgroup analysis. The included studies had a moderate risk of bias.CONCLUSION: UBT has high diagnostic accuracy for detecting H. pylori infection in patients with dyspepsia. The reliability of diagnostic meta-analytic estimates however is limited by significant heterogeneity. | Mazen Ferwana Imad Abdulmajeed Ali Alhajiahmed Wedad Madani Belal Firwana Rim Hasan Osama Altayar Paul J Limburg Mohammad Hassan Murad Bandar Knawy | 2015 | World Journal of Gastroenterology2015，21，4： | 45 |
| 2 | The 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 | 2016 | npj Computational Materials2016，，1： | 22 |

| 4 | Overview and comparison of guidelines for management of pancreatic cystic neoplasms显示文摘Pancreatic cysts are identified at an increasing frequency.Although mucinous cystic neoplasms represent a pre-malignant condition,the majority of these lesions do not progress to cancer.Over the last 10 years several societies have established guidelines for the diagnosis,initial evaluation and surveillance of these lesions.Here we provide an overview of five commonly used guidelines:2015 American Gastroenterological Association,2017 International Association of Pancreatology,American College of Gastroenterology 2018,European Study Group and American College of Radiology.We describe the similarities and differences between the methods used to formulate these guidelines,the population they target and their approaches towards initial evaluation and surveillance of cystic lesions. | Aws Hasan Kavel Visrodia James J Farrell Tamas A Gonda | 2019 | World Journal of Gastroenterology2019，25，31： | 5 |
