BACKGROUND: Statins are commonly prescribed for the secondary prevention of ischemic stroke, but there is conflicting evidence as to whether they increase the risk of intracranial hemorrhage. Lipophilic statins cross the blood-brain barrier more freely than hydrophilic statins and may therefore increase the risk of intracranial hemorrhage. OBJECTIVE: To determine whether, in older patients following ischemic stroke, receipt of lipophilic statins was associated with differences in the risk of intracranial hemorrhage...

BACKGROUND: The presence and severity of proteinuria is considered an important prognostic marker in patients with chronic kidney disease (CKD) and is associated with mortality and morbidity. Cathepsin L is highly expressed in the foot processes of podocytes in the kidney, which serves as an ultrafiltration barrier. Cathepsin L is also up-regulated in the setting of inflammation as a feature of CKD. Therefore, we postulated that proteinuria severity in CKD patients might correlate with increased serum levels of cathepsin L...

A 70-year-old previously independent man developed progressive proximal leg weakness resulting in a fall at home suffering traumatic brain injury. He was prescribed a statin medication two years prior, but this was discontinued on admission to the hospital due to concern for statin myopathy. His weakness continued to progress while in acute rehabilitation, along with the development of dysphagia requiring placement of gastrostomy tube and respiratory failure requiring tracheostomy. Corticosteroids and intravenous immunoglobulin were administered without response...

Cryptococcosis caused by Cryptococcus gattii leads to pneumonia and meningoencephalitis, and has a high mortality rate worldwide due to the inadequacy of available therapy and increasing drug resistance. There is a need to develop effective treatments, and drug repositioning is an interesting alternative to achieve new strategies to treat cryptococcosis. Atorvastatin (ATO), a statin currently used to treat hypercholesterolaemia, was tested in this study as an adjuvant to control infections caused by C. gattii...

Simvastatin (STT), a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, is widely prescribed for dyslipidemia, whereas fluoxetine (FLX) is the first-choice drug for the treatment of depression and anxiety. A recent report suggests that selective serotonin reuptake inhibitors can interact with the cytochrome P450 3A4 substrate, and another one suggests that STT enhances the antidepressant activity of FLX. However, the data are inconclusive. The present study was designed to explore the pharmacokinetic and pharmacodynamic consequences of coadministration of STT and FLX in experimental animals...

Following the continuous accumulation of evidence supporting the beneficial role of reducing low-density lipoprotein cholesterol (LDL-C) levels in the treatment and prevention of atherosclerotic cardiovascular disease and its complications, therapeutic possibilities now exist to lower LDL-C to very low levels, similar to or even lower than those seen in newborns and nonhuman species. In addition to the important task of evaluating potential side effects of such treatments, the question arises whether extremely low LDL-C levels per se may provoke adverse effects in humans...

Statins have been reported to have a potential radiosensitizing effect that has not been evaluated in clinical trials. The aim of this study was to evaluate the efficacy and safety of simvastatin in addition to whole-brain radiation therapy (WBRT) in patients with brain metastases (BM). A prospective randomized, controlled, open-label pilot study was conducted on 50 Egyptian patients with BM who were randomly assigned to receive 30-Gy WBRT (control group: 25 patients) or 30 Gy WBRT + simvastatin 80 mg/day for the WBRT period (simvastatin group: 25 patients)...

BACKGROUND: Over the past 50 years, there has been an increase in the utilization of prescribed, over-the-counter (OTC) medications, and natural health products. Although it is known that medication use is common among older persons, accurate data on the patterns of use, including the quantity and type of medications consumed in a generally healthy older population from a Canadian perspective are lacking. In this study, we study the pattern of medication use in a sedentary but otherwise healthy older persons use and determined if there was an association between medication use and aerobic fitness level...

BACKGROUND: Brain derived neurotrophic factor (BDNF) may play a central role in the pathogenesis of Alzheimer's disease (AD) through neurotrophic effects on basal cholinergic neurons. Reduced serum levels of BDND are observed among AD patients and may predict AD risk. Nevertheless, knowledge about factors associated with its levels in blood is lacking. OBJECTIVE: To identify clinical and demographic correlated of serum BDNF levels . METHODS: BDNF was measured from serum collected between 1992-1996 and 1998-2001 in participants from the Original and Offspring cohorts of the Framingham Study, respectively...

The British Association for Psychopharmacology coordinated a meeting of experts to review and revise its previous 2011 guidelines for clinical practice with anti-dementia drugs. As before, levels of evidence were rated using accepted standards which were then translated into grades of recommendation A-D, with A having the strongest evidence base (from randomised controlled trials) and D the weakest (case studies or expert opinion). Current clinical diagnostic criteria for dementia have sufficient accuracy to be applied in clinical practice (B) and both structural (computed tomography and magnetic resonance imaging) and functional (positron emission tomography and single photon emission computerised tomography) brain imaging can improve diagnostic accuracy in particular situations (B)...

Post-stroke dementia (PSD) or post-stroke cognitive impairment (PSCI) may affect up to one third of stroke survivors. Various definitions of PSCI and PSD have been described. We propose PSD as a label for any dementia following stroke in temporal relation. Various tools are available to screen and assess cognition, with few PSD-specific instruments. Choice will depend on purpose of assessment, with differing instruments needed for brief screening (e.g., Montreal Cognitive Assessment) or diagnostic formulation (e...

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 constitute a class of medications commonly used in the treatment of elevated cholesterol. However, in experimental studies, statins also have other non-cholesterol-mediated mechanisms of action, which may have neuroprotective effects. The aim of this study was to determine whether administration of atorvastatin for 7 days post-injury would improve neurological recovery in patients with mild traumatic brain injury (mTBI). The hypothesis was that atorvastatin administration would reduce post-concussion symptoms and also that atorvastatin administration for 1 week post-injury would be safe...

PURPOSE: Along with their cholesterol-lowering effect, statins have shown a wide range of pleiotropic effects potentially beneficial to neurodegenerative diseases. However, such effects are extremely elusive via the conventional oral administration. The purpose of the present study was to prepare and characterize the physicochemical properties and the in vivo biodistribution of simvastatin-loaded lecithin/chitosan nanoparticles (SVT-LCNs) suitable for nasal administration in view of an improved delivery of the statins to the brain...

Owing to statin's immune modulatory, anti-inflammatory, antioxidant, antithrombotic and endothelial function actions, they are widely used in the critical care settings in diverse disease scenarios. We aim to explore the evidence to globalize the utilization of statins in the intensive care practice for different indications. We carried out a search of the PubMed, Cochrane and EMBASE databases up to January 2016. We included review articles, meta-analyses, and original trials on the effects of statin therapy in the intensive care unit (ICU) combining the following MESH terms: 'satins', 'intensive care, 'cardiac surgery', 'sepsis', 'acute respiratory distress syndrome' 'pneumonia', subarachnoid hemorrhage', traumatic brain injury and 'critical illness'...

INTRODUCTION: Statin discontinuation has been investigated in a wide range of diseases and injuries, but there is a paucity of data in the older adult population with traumatic brain injury (TBI). The purpose of this study was to re-examine the extent to which early discontinuation of pre-injury statin (PIS) therapy increases the risk of poor patient outcomes in older adult patients suffering a TBI. METHODS: This was a retrospective observational cohort study of adult trauma patients with a blunt TBI across three trauma centres over four years...
