BACKGROUND: Statins can reduce reproductive damage induced by obesity or high-fat diet (HFD), but the specific regulatory mechanisms are largely unknown. Since mTOR/p70s6k sinaling promotes spermatogonia proliferation and spermatogenesis, we hypothesized that this pathway will be involved in the protective effects of statin in HFD-induced reproductive dysfunction. METHODS: Male Sprague Dawley rats (3 weeks old) were randomly divided into a control group (standard diet), HFD group, and a fluvastatin group (HFD + fluvastatin at 6mg/kg, once daily by oral gavage)...

BACKGROUND: A validated prediction model estimates the absolute benefit of intensive versus standard lipid-lowering therapy (LLT) with statins on next major cardiovascular events for individual patients with coronary artery disease. We aimed to assess whether targeting intensive LLT therapy to coronary artery disease patients with the highest predicted absolute benefit is cost-effective compared to treating all with standard or all with intensive LLT. METHODS AND RESULTS: A lifetime Markov model was constructed for coronary artery disease patients (n=10 000) with mean age 61 years...

BACKGROUND: In 2014, guidelines from the National Institute for Health and Care Excellence (NICE) provided updated recommendations on lipid-modifying therapy (LMT). We assessed clinical practice contemporaneous to release of these guidelines in a UK general practice setting for secondary and high-risk primary-prevention populations, and extrapolated the findings to UK nation level. METHODS: Patients from The Health Improvement Network database with the following criteria were included: lipid profile in 2014 (index date); ≥20 years of age; ≥2 years representation in database prior to index; ≥1 statin indication either for atherosclerotic cardiovascular disease (ASCVD) or the non-ASCVD conditions high-risk diabetes mellitus and/or chronic kidney disease...

OBJECTIVES: To determine the prognostic effect of Body Mass Index (BMI) in definitively treated locally advanced NSCLC patients. MATERIALS AND METHODS: In this single institution retrospective cohort study, we evaluated 291 patients who were treated for locally advanced NSCLC from 2000 to 2010. They were stratified into four BMI groups based on World Health Organization criteria: underweight (<18.5kg/m2), normal weight (18.5 to <25kg/m2), overweight (25 to <30kg/m2), and obese (≧30kg/m2)...

BACKGROUND: Despite substantial research and development investment in Alzheimer's disease (AD), effective therapeutics remain elusive. Significant emerging evidence has linked cholesterol, β-amyloid and AD, and several studies have shown a reduced risk for AD and dementia in populations treated with statins. However, while some clinical trials evaluating statins in general AD populations have been conducted, these resulted in no significant therapeutic benefit. By focusing on subgroups of the AD population, it may be possible to detect endotypes responsive to statin therapy...

Both tocotrienol and statins are suppressors of the mevalonate pathway. Supplementation of tocotrienol among statin users could potentially protect them against osteoporosis. This study aimed to compare the effects of tocotrienol and lovastatin co-supplementation with individual treatments on bone dynamic histomorphometric indices and bone morphogenetic protein-2 (BMP-2) gene expression in ovariectomized rats. Forty-eight female Sprague-Dawley rats were randomized equally into six groups. The baseline was sacrificed upon receipt...

: Hepatocellular carcinoma (HCC) is rated as the fifth most common malignancy and third in cancer related deaths worldwide. Statins, HMG-CoA reductase inhibitors, are potent cholesterol lowering drugs and recent epidemiological evidence suggests that statins prevent aggressive HCC development. Previous experiments revealed that statins downregulate phosphorylated Akt (pAkt). Here, it is demonstrated that atorvastatin decreases nuclear pAkt levels in pancreatic and lung cancer cell lines within minutes and this rapid effect is mediated by the purinergic P2X receptors...

Statins are the most widely prescribed medications worldwide for the treatment of hypercholesterolemia. They inhibit the activity of 3-hydroxy-3-methylglutaryl co enzyme A reductase (HMG-R) an enzyme involved in cholesterol synthesis in higher organisms and in isoprenoid biosynthesis in some bacteria. We hypothesized that statins may influence the microbial community in the gut through either direct inhibition or indirect mechanisms involving alterations to host responses. We therefore examined the impact of rosuvastatin (RSV) on the community structure of the murine gastrointestinal microbiota...

Statins belong to the major class of hypolipidemic drugs. They act as competitive inhibitors of 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase, a rate-limiting enzyme in the cholesterol biosynthetic pathway. This inhibition not only leads to the depletion of cholesterol and its fatty acid esters, but also to the depletion of the intermediates of this metabolic pathway (mainly pyrophosphates), which can play an important role in tumor proliferation. The aim of the current study was to establish a versatile multi-analyte method capable of quantitative determination of various currently-used statins, together with free cholesterol (FC), cholesterol esters (CEs), and some key intermediates of the mevalonate pathway occurring in human serum...

OBJECTIVES: To determine pediatricians' practices, attitudes, and barriers regarding screening for and treatment of pediatric dyslipidemias in 9- to 11-year-olds and 17- to 21-year-olds. STUDY DESIGN: American Academy of Pediatrics (AAP) 2013-2014 Periodic Survey of a national, randomly selected sample of 1627 practicing AAP physicians. Pediatricians' responses were described and modeled. RESULTS: Of 614 (38%) respondents who met eligibility criteria, less than half (46%) were moderately/very knowledgeable about the 2008 AAP cholesterol statement; fewer were well-informed about 2011 National Heart, Lung, and Blood Institute Guidelines or 2007 US Preventive Service Task Force review (both 26%)...

HIV-infected individuals are at increased risk for cardiovascular events. Widely used cardiovascular disease (CVD) risk calculators to determine indications for statin treatment are not well validated for use in the HIV-infecte population. Some experts advocate including HIV infection as an independent risk factor for CVD. The effects of antiretroviral therapy on lipid profiles and the potentially increased risk for cardiovascular events must be taken into account when selecting treatment for HIV-infected individuals...

INTRODUCTION: Macrophages play a key role in atherosclerotic plaque formation in atherosclerosis, but its detailed understanding has poorly investigated until now. Thus, we sought to demonstrate a noninvasive technique for macrophage tracking to atherosclerotic lesions in apolipoprotein E(-/-)(ApoE(-/-)) mice with an imaging system based on sodium iodide symporter (NIS) gene coupled with (99m)Tc-single-photon emission computed tomography (SPECT). METHODS AND RESULTS: Macrophage cells (RAW264...

We tested the hypothesis that a 6-week regimen of simvastatin would attenuate skeletal muscle adaptation to low-intensity exercise. Male C57BL/6J wildtype mice were subjected to 6-weeks of voluntary wheel running or normal cage activities with or without simvastatin treatment (20 mg/kg/d, n = 7-8 per group). Adaptations in in vivo fatigue resistance were determined by a treadmill running test, and by ankle plantarflexor contractile assessment. The tibialis anterior, gastrocnemius, and plantaris muscles were evaluated for exercised-induced mitochondrial adaptations (i...

BACKGROUND: Statins may reduce the risk of pulmonary and neurologic complications after cardiac surgery. METHODS: The authors acquired data for adults who had coronary artery bypass graft, valve surgery, or combined procedures. The authors matched patients who took statins preoperatively to patients who did not. First, the authors assessed the association between preoperative statin use and the primary outcomes of prolonged ventilation (more than 24 h), pneumonia (positive cultures of sputum, transtracheal fluid, bronchial washings, and/or clinical findings consistent with the diagnosis of pneumonia), and in-hospital all-cause mortality, using logistic regressions...

PURPOSE OF REVIEW: In the last 6 years, our understanding of statin-associated myopathy expanded to include not only a toxic myopathy with limited and reversible side-effects but also an autoimmune variety in which statins likely induce an autoimmune myopathy that is both associated with a specific autoantibody and responsive to immunosuppression and immune modulation. This review widens the reader's understanding of statin myopathy to include an autoimmune process. RECENT FINDINGS: Statin-associated immune-mediated myopathy provides an example of an environmental trigger (statins) directly implicated in an autoimmune disease associated with a genetic predisposition as well as potential risk factors including concomitant diseases and specific statins...

Some observational studies raised concern that statins may cause memory impairment, leading to a US Food and Drug Administration warning. Similar questions were raised regarding proprotein convertase subtilisin/kexin-type 9 inhibitors (PCSK9i) and neurocognitive function. No prospectively designed study has evaluated the relationship between long-term PCSK9i use and cognition changes. Patients with prior cardiovascular disease treated with maximally tolerated statin enrolled in FOURIER (the randomized, double-blind, placebo-controlled cardiovascular outcome study of the PCSK9i evolocumab) could participate in this prospective assessment of cognitive function (EBBINGHAUS)...
