| 1 | Antibiotic prophylaxis in variceal hemorrhage:Timing,effectiveness and Clostridium difficile rates显示文摘AIM:To investigate if antibiotics administered within 8 h of endoscopy reduce mortality or increase the incidence of Clostridium difficile infection(CDI).METHODS:A 2-year retrospective analysis of all patients who presented with first variceal hemorrhage was undertaken.The primary outcome measure was 28-d mortality.Secondary outcome measures were 28-d rebleeding rates and 28-d incidence of CDI.All patients were admitted to a tertiary liver unit with a consultantled,24-h endoscopy service.Patients received standard care including terlipressin therapy.Data collection included:primary and secondary outcome measures,timing of first administration of intravenous antibiotics,eti-ology of liver disease,demographics,endoscopy details and complications.A prospective study was undertaken to determine the incidence of CDI in the study population and general medical inpatients admitted for antibiotic therapy of at least 5 d duration.Statistical analysis was undertaken using univariate,non-parametric tests and multivariate logistic regression analysis.RESULTS:There were 70 first presentations of variceal hemorrhage during the study period.Seventy percent of cases were male and 65.7% were due to chronic alcoholic liver disease.In total,64/70(91.4%) patients received antibiotics as prophylaxis during their admission.Specifically,53/70(75.7%) received antibiotics either before endoscopy or within 8 h of endoscopy [peri-endoscopy(8 h) group],whereas 17/70(24.3%) received antibiotics at > 8 h after endoscopy or not at all(non peri-endoscopy group).Overall mortality and rebleeding rates were 13/70(18.6%) and 14/70(20%),respectively.The periendoscopy(8 h) group was significantly less likely to die compared with the non peri-endoscopy group [13.2% vs 35.3%,P = 0.04,odds ratio(OR) = 0.28(0.078-0.997)] and showed a trend towards reduced rebleeding [17.0% vs 29.4%,P = 0.27,OR = 0.49(0.14-1.74)].On univariate analysis,the non peri-endoscopy group [P = 0.02,OR = 3.58(1.00-12.81)],higher model for end-stage liver disease(MELD) score(P = 0.02),presence of hepatorenal syndrome [P < 0.01,OR = 11.25(2.24-56.42)] and suffering a clinical episode of sepsis [P = 0.03,OR = 4.03(1.11-14.58)] were significant predictors of death at 28 d.On multivariate logistic regression analysis,lower MELD score [P = 0.01,OR = 1.16(1.04-1.28)] and periendoscopy(8 h) group [P = 0.01,OR = 0.15(0.03-0.68)] were independent predictors of survival at 28 d.The CDI incidence(5.7%) was comparable to that in the general medical population(5%).CONCLUSION:Antibiotics administered up to 8 h following endoscopy were associated with improved survival at 28 d.CDI incidence was comparable to that in other patient groups. | Matthew RL Brown Graeme Jones Kathryn L Nash Mark Wright Indra Neil Guha | 2010 | World Journal of Gastroenterology2010，16，42： | 13 |

| 3 | Review of nonalcoholic fatty liver disease in women with polycystic ovary syndrome显示文摘Polycystic ovary syndrome(PCOS) is the most common endocrine disorder in reproductive-aged women. Women with PCOS frequently have metabolic complications including insulin resistance(IR), early diabetes, hypertension and dyslipidemia. Recent studies have demonstrated an association between PCOS and another metabolic complication: nonalcoholic fatty liver disease(NAFLD). NAFLD occurs as a result of abnormal lipid handling by the liver, which sensitizes the liver to injury and inflammation. It can progress to nonalcoholic steatohepatitis(NASH), which is characterized by hepatocyte injury and apoptosis. With time and further inflammation, NASH can progress to cirrhosis. Thus, given the young age at which NAFLD may occur in PCOS, these women may be at significant risk for progressive hepatic injury over the course of their lives. Many potential links between PCOS and NAFLD have been proposed, most notably IR and hyperandrogenemia. Further studies are needed to clarify the association between PCOS and NAFLD. In the interim, clinicians should be aware of this connection and consider screening for NAFLD in PCOS patients who have other metabolic risk factors. The optimal method of screening is unknown. However, measuring alanine aminotransferase and/or obtaining ultrasound on high-risk patients can be considered. First line treatment consists of lifestyle interventions and weight loss, with possible pharmacologic interventions in some cases. | Carly E Kelley Ann J Brown Anna Mae Diehl Tracy L Setji | 2014 | World Journal of Gastroenterology2014，20，39： | 11 |
| 4 | Effects of anisotropy on time-depth relation in transversely isotropic medium with a vertical axis of symmetry显示文摘It is known that rock anisotropy can significantly influence the phase and energy velocities of an elastic wave,as well as its reflection/transmission(R/T)coefficients.As a result,it can distort the velocity analysis of seismic-reflection data.In this work we present a velocity analysis for seismic-reflection data based on the available anisotropic rock parameters.We analyzed the created errors on time-depth relation of the seismic-reflection data in neglecting rock anisotropy and/or neglecting the difference between energy velocity and phase velocity,including the case of wide-angle reflection.The calculated results show that the effect of rock anisotropy on time-depth relation of seismic-reflection data is dependent not only on the values of anisotropic parameters,but also on the space arrangement of both source and receiver-array.For all studied cases(weak,moderate or strong anisotropy),we found that the effect of rock anisotropy on time-depth relation could not be neglected.Nevertheless,for the case of weak anisotropy,the energy velocity may be replaceable by the phase velocity to obtain a very good approximation on time-depth relation.Consequently,the seismic-reflection data processing algorithm for numerical computations can be simplified. | FA Lin CASTAGNA John P ZENG ZhengWen BROWN Ray L ZHAO MeiShan | 2010 | Chinese Science Bulletin2010，55，21： | 9 |
| 5 | 板块构造机制在显生宙初期发生转变显示文摘虽然目前对于板块构造何时成为主要构造机制存在争议,但是研究者普遍认为在古太古代已经完成转变。元古代时期,哥伦比亚超大陆向罗迪尼亚超大陆的转换,并未发生超大陆的完全裂解和聚合,而是岩石圈和环境的相对稳定期。相比之下,成冰期至今则发育有大量的被动大陆边缘,以及在425~225 Ma期间大幅增加的裂谷和大陆岛弧长度,表明存在与潘吉亚超大陆形成密切相关的激烈板块构造活动。 | 袁超(编译) Brown M Kirkland C L Johnson T E | 2020 | 矿物岩石地球化学通报2020，39，4： | 9 |

| 8 | Prevalence and clinical characteristics associated with left atrial thrombus detection: Apixaban显示文摘BACKGROUND The prevalence of left atrial appendage(LAA) thrombus detection by transesophageal echocardiogram(TEE) in patients with non-valvular atrial fibrillation(AF) anticoagulated with apixaban is not well defined and identification of additional risk factors may help guide the selection process for pre-procedural TEE. The purpose of our study was to retrospectively analyze the prevalence of LAA thrombus detection by TEE in patients continuously anticoagulated with apixaban for ≥ 4 wk and evaluate for any cardiac risk factors or echocardiographic characteristics which may serve as predictors of thrombus formation.AIM To retrospectively analyze the prevalence of LAA thrombus detection by TEE in patients continuously anticoagulated with apixaban.METHODS Clinical and echocardiographic data for 820 consecutive patients with AF undergoing TEE at Augusta University Medical Center over a four-year period were retrospectively analyzed. All patients(apixaban: 226) with non-valvular AF and documented compliance with apixaban for ≥ 4 wk prior to index TEE were included.RESULTS Following ≥ 4 wk of continuous anticoagulation with apixaban, the prevalence ofLAA thrombus and LAA thrombus/dense spontaneous echocardiographic contrast was 3.1% and 6.6%, respectively. Persistent AF, left ventricular ejection fraction < 30%, severe LA dilation, and reduced LAA velocity were associated with thrombus formation. Following multivariate logistic regression, persistent AF(OR: 7.427; 95%CI: 1.02 to 53.92; P = 0.0474), and reduced LAA velocity(OR:1.086; 95%CI: 1.010 to 1.187; P = 0.0489) were identified as independent predictors of LAA thrombus. No Thrombi were detected in patients with a CHA2 DS2-VASc score ≤ 1.CONCLUSION Among patients with non-valvular AF and ≥ 4 wk of anticoagulation with apixaban, the prevalence of LAA thrombus detected by TEE was 3.1%. This suggests that continuous therapy with apixaban does not completely eliminate the risk of LAA thrombus and that TEE prior to cardioversion or catheter ablation may be of benefit in patients with multiple risk factors. | Hoyle L Whiteside Arun Nagabandi Kristen Brown Deepak N Ayyala Gyanendra K Sharma | 2019 | World Journal of Cardiology2019，11，2： | 2 |
