Background: With recent legislation imposing penalties on hospitals for above-average 30-day all-cause readmissions for patients with acute decompensated heart failure (ADHF), there is concern these penalties will more heavily impact hospitals serving socioeconomically vulnerable and underserved populations. Hypothesis: Patients with ADHF and low socioeconomic status have better postdischarge mortality and readmission outcomes when cardiologists are involved in their in-hospital care. Methods: We retrospectively searched the electronic medical record for patients hospitalized for ADHF from 2001 to 2010 in 3 urban hospitals within a large university-based health system. These patients were divided into 2 groups based on whether a cardiologist was involved in their care or not. Measured outcomes were 30-and 60-day postdischarge mortality and readmission rates. Results: Out of the 7516 ADHF patients, 1434 patients were seen by a cardiologist (19%). These patients had lower 60-day mortality (5.4% vs 7.0%; hazard ratio [HR]: 0.70, 95% confidence interval [CI]: 0.52-0.96, P = 0.034) and lower 30-and 60-day readmission rates (16.7% vs 20.6%; HR: 0.76, 95% CI: 0.66-0.89, P = 0.002, and 26.1% vs 30.2%; HR: 0.81, 95% CI: 0.72-0.92, P = 0.003, respectively). There was no significant difference in the in-hospital mortality between the 2 groups. Compared with other races, whites with systolic HF have marginally lower HF-related readmission rates when treated by cardiologists. Conclusions: In this cohort of ADHF patients from the Bronx, New York, involvement of a cardiologist resulted in improved short-term mortality and readmission outcomes compared with treatment by general internal medicine.
Amikacin (AMIK) is an aminoglycoside antibiotic that possesses considerable nephrotoxic adverse effects. This study examined the protective effects of vitamin E (VIT. E) or rosuvastatin (ROSU) against AMIK-induced nephrotoxicity. For this purpose, eight groups of rats were used. Two control groups received saline and vehicle, AMIK group (1.2 g/kg, i.p.), VIT. E group (1000 mg/kg; p.o.), ROSU group (10 mg/kg; p.o.), AMIK + VIT. E group, AMIK + ROSU group, and combination group. The results showed that AMIK significantly increased serum levels of urea and creatinine. Meanwhile, serum levels of total protein and albumin were decreased. The kidney content of malondialdehyde was increased, whereas glutathione content and catalase activity were decreased. Tumor necrosis factor-α and nuclear transcriptional factor levels were increased. Conversely, administration of VIT. E and/or ROSU with AMIK ameliorated such damage and reduced DNA fragmentation, apoptosis, and necrosis. In conclusion, co-administration of VIT. E, ROSU, or their combination alleviated AMIK-induced nephrotoxicity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
