UNLABELLED BACKGROUND The relation between medications that release nitric oxide, such as nitroglycerin and other nitrovasodilators, and upper gastrointestinal bleeding is uncertain. In animals, these medications reduce the gastric damage induced by nonsteroidal antiinflammatory drugs. Nitric oxide, however, inhibits platelet aggregation and may contribute(More)
To evaluate the impact of improved wood burning stoves on indoor air pollution, 53 homes in a rural town in Michoacán, Mexico, were selected from a health intervention study and monitored before and after receiving improved wood-burning stoves. Fine particulate matter--particles with aerodynamic diameter less than 2.5 microm (PM(2.5))--concentrations were(More)
BACKGROUND Most patients with vascular-occlusive diseases benefit from low-dose aspirin (75-325 mg/day). However, they have an increased risk of upper gastrointestinal bleeding (UGIB). AIMS To analyse the incidence and factors influencing the occurrence of UGIB in patients taking low-dose aspirin for the prevention of cardiovascular diseases outside(More)
BACKGROUND Aspirin is valuable for preventing vascular events, but information about ulcer frequency is necessary to inform risk-benefit decisions in individual patients. AIM To determine ulcer prevalence and incidence in a population representative of those given aspirin therapy and evaluate risk predictors. METHODS Patients taking aspirin 75-325 mg(More)
AIM To evaluate the role of Helicobacter pylori infection and other clinical factors in the risk of upper gastrointestinal bleeding in patients taking low-dose aspirin. SUBJECTS AND METHODS A case-control study was carried out of consecutive current users of low-dose aspirin admitted because of upper gastrointestinal bleeding. Within a cohort of 695(More)
This paper introduces a new clinical distortion index able to measure the decrease in diagnostic content in compressed echocardiograms. It is calculated using cardiologists' answers to a clinical testbed composed of two types of tests: one blind and the other semi-blind. This index may be used to compare clinical performance among video codecs from a(More)
BACKGROUND & AIMS Current studies lack appropriate data on aspirin and other risk factors for gastrointestinal perforation. The aim of this study was to obtain the best estimate on aspirin and nonaspirin nonsteroidal anti-inflammatory drug (NSAID) use in these patients. METHODS In 76 consecutive patients with gastrointestinal perforation and 152 matched(More)
In this work we have analyzed changes in the heart rate variability (HRV) during exercise test comparing them with the ST deviation criteria to improve the diagnostic value of the exercise test. Coronary angiography was considered as gold standard to establish the classification of patients in two groups (ischemic and non-ischemic). ST deviations and HRV(More)
OBJECTIVE The purpose of this study was to identify factors associated with increased risk of adverse systemic reactions to cluster allergen immunotherapy and to create a preliminary predictive clinical model. METHODS In a prospective observational study, the tolerance of 611 patients with seasonal respiratory diseases who were receiving cluster(More)
