Intestinal preparation prior to capsule endoscopy administration

引用

World Journal of Gastroenterology 2008年第37期14卷 5773-5775页

In order to have an adequate view of the whole small intestine during capsule endoscopy, the preparation recommended consists of a clear liquid diet and an overnight fast. However, visualization of the small bowel during video capsule endoscopy can be impaired by intestinal contents. To improve mucosal visualization, some authors have evaluated different regimens of preparation. There is no consensus about the necessity of intestinal preparation for capsule endoscopy and it should be interesting to develop adequate guidelines to improve its efficacy and tolerability. Moreover, the effect of preparation type (purgative) on intestinal transit time is not clear. Since a bowel preparation cannot defini-tively improve its visibility (and theoretically the yield of the test), it is not routinely recommended.

In this talk I report on recent work related to the dynamical generation of baryonic resonances, some made up from pseudoscalar meson-baryon, others from vector meson-baryon and a third type from two meson-one baryon systems. We can establish a correspondence with known baryonic resonances, reinforcing conclusions previously drawn and bringing new light on the nature of some baryonic resonances of higher mass.

Prognostic significance of heart rate in hospitalized patients presenting with myocardial infarction

World Journal of Cardiology 2012年第1期4卷 15-19页

作者： Lorenzo Fácila Pedro Morillas Juan Quiles Federico Soria Alberto Cordero Pilar Mazón Manuel Anguita Cándido Martín-Luengo Jose Ramón gonzalez-Juanatey vicente Bertomeu Department of Cardiology Consorcio Hospitalario General de Valencia Department of Cardiology Hospital Universitario de San Juan Department of Cardiology Hospital Virgen de la Arrixaca Department of Cardiology Hospital Clínico Universitario Santiago de Compostela Department of Cardiology Hospital Reina Sofía Department of Cardiology Hospital Universitario de Salamanca

AIM: To investigate the prognostic significance of resting heart rate in patients with acute coronary syndrome (ACS), independent of other known factors. METHODS: Patients 40 years of age or older who had been admitted with acute coronary syndrome (ACS) to one of the 94 hospitals participating in the Prevalence of Peripheral Arterial Disease in Patients with Acute Coronary Syndrome (PAMISCA) study were included. Patients were divided into two groups based on their resting heart rate (HR ≥ or < 70 bpm). Complications were recording during a follow-up period of 1 year. RESULTS: There were 1054 ACS patients analyzed (43.5% with ST segment elevation and 56.5% without elevation). Mean age was 66.6 ± 11.7 years, 70.6% were male and 29.4% of subjects were female. During follow-up, more patients in the HR ≥ 70 bpm group were hospitalized for heart failure and they also had a higher mortality rate. In the multivariate analysis, a heart rate of ≥ 70 bpm was independently related to overall mortality during the follow-up period (hazard ratio 2.5; 95% confidence interval, 1.26-4.97, P = 0.009). CONCLUSION: A resting heart rate ≥ 70 bpm in patients who survive an ACS is an indicator of a high risk of suffering cardiovascular events during follow-up.
