O’Connor, M.D. For the NHLBI Center Failure Clinical Research Network: Diuretic Strategies in Individuals with Acute Decompensated Center Failure Acute decompensated heart failure may be the most common cause of hospital admissions among individuals older than 65 years and is responsible for more than 1 million hospitalizations annually in the usa. 1 Intravenous loop diuretics are an essential component of current treatment and are administered to approximately 90 percent of patients who are hospitalized with heart failure.2 Despite years of medical experience with these agents, prospective data to steer the usage of loop diuretics are sparse, and current recommendations are based primarily on expert opinion.3,4 As a complete result, clinical practice varies widely with regard to both the mode of administration and the dosing.5 Furthermore, observational studies show associations between high doses of diuretics and adverse scientific outcomes, including renal failure, progression of heart failure, and death.6-8 Such observations are confounded, however, because high doses of diuretics may be a marker for better severity of illness rather than a mediator of adverse outcomes.Through April 24 From March 24, 2009, a total of 214 er consultations for situations of pneumonia or influenza-like disease were registered, 98 which required hospitalization. Of these cases, 18 confirmed cases of S-OIV contamination, with pneumonia and influenza-like illness, will be the focus of the report. Characteristics of the 18 study sufferers with confirmed S-OIV illness are listed in Table 1Table 1Features of the 18 Study Patients Who have Had Confirmed Illness with Novel Swine-Origin Influenza A Virus., and Table S1 in the Supplementary Appendix . The ages of the sufferers ranged from 9 a few months to 61 years . More than half the patients had been between 13 and 47 years, and 90 percent were less than 52 years. Nine sufferers were male. All individuals resided in the Mexico City greater metropolitan area.
