OBJECTIVE: There is an international trend towards recommending medication to prevent cardiovascular disease (CVD) in individuals at increasingly lower cardiovascular risk. We assessed the cost-effectiveness of a population approach with a polypill including a statin (simvastatin 20 mg) and three antihypertensive agents (amlodipine 2.5 mg, losartan 25 mg and hydrochlorothiazide 12.5 mg) and periodic risk assessment with different risk thresholds. METHODS: We developed a microsimulation model for lifetime predictions of CVD events, diabetes, and death in 259 146 asymptomatic UK Biobank participants aged 40-69 years...

Natural polymer-based hydrogel films have great potential for biomedical applications and are good candidates for wound dressings. In this study, we aimed to develop simvastatin-loaded crosslinked alginate-pectin hydrogel films by ionic crosslinking to improve the mechanical characteristics, wound fluid uptake and drug release behavior. Alginate-pectin hydrocolloid films were chemically crosslinked by immersing in different concentrations of CaCl2 (0.5-3% w/v) for 2-20min. The degree of crosslinking was influenced by both contact time and CaCl2 concentration...

BACKGROUND: Rhabdomyolysis is a widely recognized yet rare complication in statin use. Rhabdomyolysis might be triggered by the prescription of high doses of statins or by statin accumulation due to interactions with concomitant medication. Muscle cell destruction as evidenced by myoglobin elevation can induce potentially life-threatening acute renal failure. CASE PRESENTATION: We report a case of a 70-year-old obese white man with sudden onset of severe rhabdomyolysis with consecutive renal failure...

Titanium implants are widely used on an increasing number of patients in orthopedic and dental medicine. Despite the good survival rates of these implants, failures that lead to important socio-economic consequences still exist. Recently, research aimed at improving implant fixation, a process called osseointegration, has focused on a new, inovative field: systemic delivery of drugs. Following implant fixation, patients receive systemic drugs that could either impair or enhance osseointegration; these drugs include anabolic and anti-catabolic bone-acting agents in addition to new treatments...

BACKGROUND: Pulmonary hypertension (PH) is a devastating disorder, for which no therapy is curative. It has been reported that pulmonary vascular remodeling, associated with increasing mean pulmonary arterial pressure and upregulated expression of endothelial nitric oxide synthase (eNOS), endothelin-1 (ET-1), RhoA/RhoH-kinase results in the development of PH. Oxidative stress and the RhoA/Rho-kinase pathway are also thought to be involved in the pathophysiology of PH. Statins are 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (HMG-CoA reductase inhibitors) with pleiotropic effects and are potential agents for the treatment of PH...

Statins are hypocholesterolemic drugs that are prescribed for patients with an increased risk of cardiovascular and cerebrovascular complications. Ezetimibe has an atheroprotective activity through inhibition of the expression of vascular adhesion molecule-I and vascular CD14, a marker of the infiltration of mononuclear leukocytes. Ezetimibe reduces the amount of chemoattractant protein-1 that is available for monocytes and macrophages and alters the activity of nuclear factor κB in leukocytes. The mechanisms of action of statins complement those of ezetimibe...

: Among those with moderate-to-advanced chronic kidney disease, the relationship between blood pressure (BP) and cardiovascular disease seems U shaped but is loglinear in apparently healthy adults. The SHARP (Study of Heart and Renal Protection) randomized 9270 patients with chronic kidney disease to ezetimibe/simvastatin versus matching placebo and measured BP at each follow-up visit. Cox regression was used to assess the association between BP and risk of cardiovascular disease among (1) those with a self-reported history of cardiovascular disease and (2) those with no such history and, based on plasma troponin-I concentration, a low probability of subclinical cardiac disease...

The conventional treatment for toxoplasmosis with pyrimethamine and sulfadiazine shows toxic effects to the host, and it is therefore necessary to search for new drugs. Some studies suggest the use of statins, which inhibit cholesterol synthesis in humans and also the initial processes of isoprenoid biosynthesis in the parasite. Thus, the objective of this study was to evaluate the activity of the statins pravastatin and simvastatin in HeLa cells infected in vitro with the RH strain of T. gondii. HeLa cells (1×10(5)) were infected with T...

Current treatments for chronic Chagas cardiomyopathy, a disease with high mortality rates and caused by the protozoan Trypanosoma cruzi, are unsatisfactory. Myocardial inflammation, including endothelial activation, is responsible for the structural and functional damage seen in the chronic phase. The clinical efficacy of benznidazole could be improved by decreasing chronic inflammation. Statins, which have anti-inflammatory properties, may improve the action of benznidazole. Herein, the action of simvastatin in a murine model of chronic Chagas cardiomyopathy and the link with the production of the pro-resolving eicosanoid 15-epi-lipoxin A4, produced by 5-lipoxygenase, are evaluated...

Inflammation plays a pivotal role throughout the formation and progression of atherosclerosis. As the most representative inflammatory marker, C-reactive protein (CRP) directly participates in the initiation and development of atherosclerosis. The elevated homocysteine (Hcy) level in plasma is an independent risk factor for atherosclerosis. We previously reported that Hcy produces a pro-inflammatory effect by stimulating CRP expression in vascular smooth muscle cells (VSMCs). The present study observed the effect of simvastatin on Hcy-induced CRP expression in VSMCs and the molecular mechanisms...
