Background
Few data are available on the prevalence of erosive and severe esophagitis in Western countries.Objective
To retrospectively determine the prevalence and the factors predicting erosive esophagitis and severe esophagitis in a large series of endoscopies in Spain.Design
Retrospective observational study. A multivariate analysis was performed to determine variables predicting severe esophagitis.Setting
Databases of 29 Spanish endoscopy units.Patients
Patients submitted to a diagnostic endoscopy during the year 2005.Interventions
Retrospective review of the databases.Main Outcome Measurements
Esophagitis severity (graded according to the Los Angeles classification) and associated endoscopic findings.Results
Esophagitis was observed in 8.7% of the 93,699 endoscopies reviewed. Severe esophagitis (LA grade C or D) accounted for 22.5% of cases of the disease and was found in 1.9% of all endoscopies. Incidences of esophagitis and those of severe esophagitis were 86.2 and 18.7 cases per 100,000 inhabitants per year respectively. Male sex (OR 1.89) and advanced age (OR 4.2 for patients in the fourth age quartile) were the only variables associated with severe esophagitis. Associated peptic ulcer was present in 8.8% of cases.Limitations
Retrospective study, no data on individual proton pump inhibitors use.Conclusions
Severe esophagitis is an infrequent finding in Spain. It occurs predominantly in males and in older individuals. Peptic ulcer disease is frequently associated with erosive esophagitis. 相似文献996.

BackgroundAlthough the short-term benefit of primary percutaneous coronary intervention (PCI) in elderly patients with ST-elevation myocardial infarction (STEMI) has been demonstrated, the final long-term survival benefit is as yet unknown.AimTo assess the final survival benefit of primary PCI as compared to thrombolytic therapy in patients over 75 years of age.MethodsPatients > 75 years with STEMI were randomised to either primary PCI or thrombolysis. Long-term data on survival were available for all patients.ResultsA total of 46 patients were randomised to primary PCI, 41 to thrombolysis. There were no significant differences in baseline variables. After a maximum of 20 years’ follow-up, all patients had passed away. The patients randomised to thrombolysis died after a mean follow-up duration of 5.2 years (SD 4.9) compared to 6.7 years (SD 4.8) in patients randomised to primary PCI (p = 0.15). Thus, the mean final survival benefit of primary PCI was 1.5 years.ConclusionThe final survival benefit of primary PCI as compared to thrombolysis in elderly patients with STEMI is 1.5 years and their life expectancy increases by 28.8%. 相似文献

The Gene Ontology (GO) is a collaborative effort that provides structured vocabularies for annotating the molecular function, biological role, and cellular location of gene products in a highly systematic way and in a species-neutral manner with the aim of unifying the representation of gene function across different organisms. Each contributing member of the GO Consortium independently associates GO terms to gene products from the organism(s) they are annotating. Here we introduce the Reference Genome project, which brings together those independent efforts into a unified framework based on the evolutionary relationships between genes in these different organisms. The Reference Genome project has two primary goals: to increase the depth and breadth of annotations for genes in each of the organisms in the project, and to create data sets and tools that enable other genome annotation efforts to infer GO annotations for homologous genes in their organisms. In addition, the project has several important incidental benefits, such as increasing annotation consistency across genome databases, and providing important improvements to the GO's logical structure and biological content. 相似文献

本文采用经颅多普勒超声(TCD)技术对三组足月初产孕妇共30例进行了TCD主要指标的测定,经统计学处理,正常组、轻度妊高征组的TCD主要指标均在正常人的范围内。而中度、重度妊高征组的TCD主要指标高于正常范围,有显著差异(P<0.0005),左右两侧血管的血流速度不相等,差异超过19.5cm/s。作者等认为TCD技术是一种操作简单,无创伤性、重复,性好、数据可靠的新型检测手段。将TCD作为中度,重度妊高征足月初产孕妇产前、产后的主要监护手段是有一定的现实临床意义。 相似文献
