Is Atrial Fibrillation a Risk Factor for Gastroesophageal Reflux Disease Occurrence?

Recent studies have reported an association between gastroesophageal reflux disease (GERD) and atrial fibrillation (AF). The objective of the present study was to evaluate whether AF is one of the risk factors for GERD occurrence.In this hospital-based, retrospective, case–control study, the patients were classified into 2 groups. The patients diagnosed with new AF were assigned to the AF group (n = 1612); those diagnosed without AF and GERD were assigned to the control group (n = 1612). The subjects in the control group were selected from outpatients of total healthcare center without a history of AF or GERD, and matched for age and gender. We evaluated the incidence of GERD and risk factors for GERD occurrence between the 2 groups.The number of patients experiencing occurrence of GERD during the follow-up period was significantly higher in the AF group than those in the control group, respectively (129 patients vs 98 subjects, P = 0.037). The incidence of GERD was significantly higher in the AF group than in the control group by Kaplan–Meier analysis with log-rank test (P = 0.008). The AF group''s adjusted hazard ratio of GERD occurrence against that of the control group was 1.37 (95% confidence interval [CI]: 1.16–1.57; P = 0.009) according to Cox''s proportional hazard model.The presence of AF appears to increase the incidence of GERD and may be considered a risk factor for the development of GERD. Further, large prospective and cohort studies will be required to better establish the correlation of GERD with AF.     

针刺辅助治疗难治性肠易激综合征临床试验方案关键点设计的思考＊

肠易激综合征（Irritable bowel syndrome，IBS）是临床常见病、多发病，其治疗方法丰富，但部分患者疗效欠佳，发展成难治性IBS。目前国内外关于针灸治疗难治性IBS的临床随机对照试验尚不多见。本文立足试验方案设计的“PICOS”原则，从研究对象及诊断标准、干预措施、对照措施、结局指标四个方面入手，重点探讨针刺辅助治疗难治性肠易激综合征临床试验设计的关键要点。从选择特色优势病种、明确诊断标准、制定符合临床实际的干预方案、运用符合目标的安慰针刺、结合研究设计和目的选定结局指标几个角度，阐述试验相关环节设计的原因和思考。     

简明膳食自评工具在食管癌术后患者中的应用评价

目的将简明膳食自评工具（SDSAT）应用在食管癌术后患者中，评价其信度和效度。 方法本研究通过3个研究分别测量SDSAT的评定者间信度、重测信度和预测效度。研究A选择食管癌术前患者60例，由2位研究者分别进行SDSAT的测量，评价评定者间信度。研究B最终纳入食管癌术后1个月患者30例进行SDSAT的测量，间隔2周复测1次，比较2次结果，评价重测信度。研究C最终共纳入171例食管癌患者通过测量术前、术后1个月和术后3个月3个时间点测量，评价SDSAT对前白蛋白含量的预测程度。 结果评定者间信度是0.854（P<0.01）。 重测信度是0.782（P<0.01）。通过广义预测方程发现SDSAT对患者的前白蛋白含量预测效果好（P<0.01）。结论SDSAT信效度好，适合应用于评价食管癌术后患者的饮食状况。
