1Risk factors associated with the development of ischemic colitis显示文摘AIM:To ascertain the role of cardiovascular risk factors,cardiovascular diseases,standard treatments and other diseases in the development of ischemic colitis(IC).METHODS:A retrospective,case-control study was designed,using matched data and covering 161 incident cases of IC who required admission to our hospital from 1998 through 2003.IC was diagnosed on the basis of endoscopic findings and diagnostic or compatible his-tology.Controls were randomly chosen from a cohort of patients who were admitted in the same period and required a colonoscopy,excluding those with diagnosis of colitis.Cases were matched with controls(ratio 1:2),by age and sex.A conditional logistic regression was performed.RESULTS:A total of 483 patients(161 cases,322 con-trols)were included;mean age 75.67±10.03 years,55.9%women.The principal indications for colonos-copy in the control group were lower gastrointestinal hemorrhage(35.4%),anemia(33.9%),abdominal pain(19.9%)and diarrhea(9.6%).The endoscopic findings in this group were hemorrhoids(25.5%),diverticular disease(30.4%),polyps(19.9%)and colorectal cancer(10.2%).The following variables were associated with IC in the univariate analysis:arterial hypertension(P= 0.033);dyslipidemia(P<0.001);diabetes mellitus(P =0.025);peripheral arterial disease(P=0.004);heart failure(P=0.026);treatment with hypotensive drugs(P=0.023);angiotensin-converting enzyme inhibitors;(P=0.018);calcium channel antagonists(P=0.028);and acetylsalicylic acid(ASA)(P<0.001).Finally,the following variables were independently associated with the development of IC:diabetes mellitus[odds ratio(OR)1.76,95%confidence interval(CI):1.001-3.077,P=0.046];dyslipidemia(OR 2.12,95%CI:1.26-3.57,P=0.004);heart failure(OR 3.17,95%CI:1.31-7.68,P=0.01);peripheral arterial disease(OR 4.1,95%CI:1.32-12.72,P=0.015);treatment with digoxin(digitalis)(OR 0.27,95%CI:0.084-0.857,P=0.026);and ASA(OR 1.97,95%CI:1.16-3.36,P=0.012).CONCLUSION:The development of an episode of IC was independently associated with diabetes,dyslipid-emia,presence of heart failure,peripheral arterial dis-ease and treatment with digoxin or ASA.Joaquín Cubiella Fernández Luisa Núez Calvo Elvira González Vázquez Maria Jesús García García Maria Teresa Alves Pérez Isabel Martínez Silva Javier Fernández Seara 2010World Journal of Gastroenterology2010,16,36:27
2固定低剂量三联抗高血压药物与常规治疗对斯里兰卡轻度至中度高血压患者血压控制的疗效差异:一项随机临床试验显示文摘控制不良的高血压是全球领先的公共卫生问题,需要新的治疗策略。该研究评估低剂量三联抗高血压药物治疗是否能达到比常规治疗更好的血压控制。研究者纳入2016年2月至2017年5月在斯里兰卡11所城市医院诊所就诊的需要开始抗高血压治疗(未治疗的患者)或接受单药治疗的患者,进行低剂量三联降压与常规治疗比较的随机、开放性试验,随访至2017年10月。Web-ster R Salam A de Silva HA Selak V Stepien S Rajapakse S Amarasekara S Amarasena N Billot L de Silva AP Fernando M Guggilla R Jan S Jayawardena J Maulik PK Mendis S Munasinghe J Naik N Prabhakaran D Ranasinghe G Thom S Tisserra N Senaratne V Wijekoon S Wijeyasingam S Rodgers A Patel A 刘莉 叶鹏 2018中华高血压杂志2018,26,12:7
