86 to 1.05; P=0.35). Overall rates of death were 52.6 and 52.3 per 1000 patient-years,
respectively (hazard ratio, 1.00; 95% CI, 0.88 to 1.14; P=0.98). Rates of hospitalization for cardiovascular causes that contributed to the primary outcome were 70.6 and 74.3 per 1000 patient-years, respectively (hazard ratio, 0.95; 95% CI, 0.85 to 1.08; P=0.44).

Conclusions: Irbesartan did not improve the outcomes of patients with heart failure and a preserved left ventricular ejection fraction. (ClinicalTrials.gov number, NCT00095238.).”
“Since the emergence of the severe acute respiratory syndrome (SARS) to date, neither an effective antiviral drug nor a vaccine against SARS is available. However, it was found that a mixture of two PCI-32765 purchase HIV-1 proteinase inhibitors, lopinavir and ritonavir, exhibited some signs of effectiveness against the SARS virus. To understand the fine details of the molecular interactions between these proteinase
inhibitors and the SARS virus via complexation, molecular dynamics simulations were carried out for the SARS-CoV 3CLP(pro) free enzyme (free SARS) and its complexes with lopinavir (SARS-LPV) and ritonavir (SARS-RTV). The results show that flap closing was clearly observed when the inhibitors bind to the active site of SARS-CoV 3CL(pro). The binding affinities of LPV and RTV to SARS-CoV 3CL(pro) do not show any significant difference. In addition, six hydrogen bonds were detected in the SARS-LPV system, while seven hydrogen bonds were found in SARS-RTV complex. (C) 2008 Elsevier Ltd. All rights reserved.”
“Background Diabetic
retinopathy remains a leading cause of visual loss in people of working age. We examined whether candesartan treatment could slow the progression and, secondly, induce regression of retinopathy in people with type 2 diabetes.
Methods We did a randomised, double-blind, parallel-group, placebo-controlled trial in 309 centres worldwide. We recruited normoalbuminuric, normotensive, or treated hypertensive people with type 2 diabetes with mild to moderately severe retinopathy learn more and assigned them to candesartan 16 mg once a day or placebo. After a month, the dose was doubled to 32 mg once per day. Investigators and patients were unaware of the treatment allocation status. Progression of retinopathy was the primary endpoint, and regression was a secondary endpoint. Analysis was by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT00252694.
Findings 1905 participants (aged 37-75 years) were randomised to candesartan (n=951) or placebo (n=954). 161 (17%) patients in the candesartan group and 182 (19%) in the placebo group had progression of retinopathy by three steps or more on the Early Treatment Diabetic Retinopathy Study scale. The risk of progression of retinopathy was non-significantly reduced by 13% in patients on candesartan compared with those on placebo (hazard ratio [HR] 0.87, 95% CI 0.70-1.
