Association of height with outcomes in patients with acute myocardial infarction receiving reperfusion therapy

Data were evaluated for patients with acute ST-elevation myocardial infarction (n = 94,182) enrolled in 6 large clinical trials evaluating the efficacy of various reperfusion strategies. It was found that compared with the tallest quartile, incidences of in-hospital reinfarction, stroke, major bleeding, cardiogenic shock, heart failure, and death in the shortest group were 1.4, 1.7, 1.7, 1.8, 1.9, and 2.4 times greater, respectively. Although a strong inverse association of height was observed with unadjusted 30-day mortality (p <0.001), it was attenuated after adjustment for confounders, including weight, and appeared to be nonlinear, such that for height 165 cm, the OR for a 10-cm increase in height was 0.962 (95% CI 0.896 to 1.033). These data indicate that height-related differences in 30-day mortality are explained in large part by height-related differences in patients' clinical characteristics.     

Protective effect of a 50% hydroalcoholic fruit extract of Emblica officinalis against anti-tuberculosis drugs induced liver toxicity

The present report showed the hepatoprotective property of a 50% hydroalcoholic extract of the fruits of Emblica officinalis (fruit) (EO-50) against antituberculosis (anti-TB) drugs-induced hepatic injury. The biochemical manifestations of hepatotoxicity induced by rifampicin (RIF), isoniazid (INH) and pyrazinamide (PZA), either given alone or in combination were evaluated. In vitro studies were done on suspension cultures of rat hepatocytes while sub-acute studies were carried out in rats. The hepatoprotective activity of EO-50 was found to be due to its membrane stabilizing, antioxidative and CYP 2E1 inhibitory effects.     

Establishing the identity of the massacred tigress in a case of wildlife crime

We report a case study, where we have established the identity from a challenging biological sample of a deceased tigress by parentage analysis. A wildlife crime was committed in one of the zoological parks in India in the year 2000, where one young tigress was killed for its claws. This was of media interest for several days and remained an unsolved case for four years. A framed claw and decomposed tiger hide were seized from the accused in 2005. Biological samples of the victim tigress was not available for further forensics examination, therefore; DNA samples of the biological parents and a male sibling were used to establish the identity of the claw using STRs and mitochondrial DNA markers. Our analysis indicates that the seized claw belongs to the victim tigress.

Clin Transplant 2011: 25: 375–379. © 2010 John Wiley & Sons A/S. Abstract: Post‐transplant glomerulonephritis (PTGN) accounts for 4–10% of late graft loss. Six consecutive patients who developed PTGN 3–72 months post‐transplant presented to our center with deteriorating kidney function and proteinuria. Three had focal segmental glomerulosclerosis; one had membranoproliferative glomerulonephritis Type 1; one recurrent membranous nephropathy; and one recurrent immunoglobin A nephropathy. All six were treated with an aggressive immunosuppression regimen including rituximab, pulse steriods and/or maximization of mycophenolic acid and calcineurin inhibitor therapy. Four of the six patients received plasma exchange. The patients were followed for a minimum of nine months after treatment. Proteinuria decreased from 7.2 ± 4.4 to 1.4 ± 1.5 g (p = 0.04), while mean estimated glomerular filtration rate was 31.2 ± 13.1 and 42.5 ± 21.7 mL/min (p = 0.07) at nine months. No adverse events were noted. These observations suggest that immune modulating therapy may be of benefit in the treatment of PTGN.     

Racial differences in the characteristics of patients admitted for acute decompensated heart failure and their relation to outcomes: results from the OPTIME-CHF trial

BackgroundRecent data suggest that differences in response to therapy and survival exist between African Americans and Caucasians with heart failure. Whether these differences exist in acute decompensated heart failure (ADHF) is uncertain.Methods and ResultsWe analyzed data from the OPTIME-CHF (Outcomes of a Prospective Trial of Intravenous Milrinone for Exacerbations of Chronic Heart Failure) study, a randomized trial of intravenous milrinone versus placebo in 949 patients hospitalized with ADHF. We evaluated differences in clinical characteristics, outcomes, and response to milrinone therapy in African American patients compared with Caucasians. The primary end point of OPTIME-CHF was days hospitalized for cardiovascular causes or death within 60 days of randomization. Thirty-three percent (n = 310) of patients were African American. African American patients were younger (57 vs. 70 years, P < .0001) and more likely to have non-ischemic cardiomyopathy (74% vs. 36%, P < .0001). In unadjusted analysis, African American patients had a lower 60-day mortality (5% vs. 12%, P = .0004) and tended to have better overall clinical outcomes. After adjustment for baseline differences, however, these differences were no longer significant. We found no differential effect of milrinone therapy by race.ConclusionAfrican American patients with acute decompensated heart failure present with a different clinical profile than Caucasian patients. Although unadjusted clinical outcomes are better for African Americans presenting with ADHF, these differences diminished after adjustment for baseline characteristics.     

Effect of prophylactic ondansetron on postoperative nausea and vomiting in patients on preoperative steroids undergoing craniotomy for supratentorial tumors

The exact incidence of postoperative nausea and vomiting (PONV) in patients on steroids undergoing neurosurgical procedures is not known. This prospective randomized double-blind study was planned to know the efficacy of prophylactic ondansetron in the prevention of PONV in patients on steroids as compared with placebo. Seventy adult patients of either sex who had received preoperative steroids (dexamethasone) for at least 24 hours and were scheduled to undergo craniotomy for supratentorial tumors were included. Patients were randomly allocated using a randomization chart to 1 of the 2 groups to receive either ondansetron 4 mg (group O) or 0.9% saline (group S) intravenously at the time of dural closure. Numeric Rating Scale score for nausea and pain intensity was recorded preoperatively and till 24 hours postoperatively. The 6-hour postoperative nausea score was significantly lower in group O [median, 0; interquartile range (IQR), 0 to 20] than in group S (median, 20; IQR, 0 to 20) (P<0.05). The incidence of vomiting was lower in group O (23%) than in group S (46%) (P<0.05). The total number of emetic episodes, the number of doses of rescue antiemetics given in the first 6 postoperative hours, and the total number of rescue antiemetics given were significantly lower in group O than in group S (P<0.05). Intravenous administration of 4 mg of ondansetron at the time of dural closure was effective in reducing the incidence of PONV and the rescue antiemetics requirement in patients on preoperative steroids undergoing craniotomy for supratentorial tumors.
