REVIEW

Premature mortality due to cardiovascular disease in those with schizophrenia is the largest lifespan disparity in the US and is growing; adults in the US with schizophrenia die, on average, 28 years earlier than those in the general population. The rate of smoking prevalence among individuals with schizophrenia is estimated to be from 64 to 79%. Smokers with schizophrenia have historically been excluded from most large nicotine-dependence treatment studies. However, converging evidence indicates that a majority of smokers with schizophrenia want to quit smoking, and that available pharmacotherapeutic smoking cessation aids are well tolerated by this population of smokers and are effective when combined with behavioral treatment...

Renal function plays a central role in cardiovascular, kidney, and multiple other diseases, and many existing and novel therapies act through renal mechanisms. Even with decades of accumulated knowledge of renal physiology, pathophysiology, and pharmacology, the dynamics of renal function remain difficult to understand and predict, often resulting in unexpected or counterintuitive therapy responses. Quantitative systems pharmacology modeling of renal function integrates this accumulated knowledge into a quantitative framework, allowing evaluation of competing hypotheses, identification of knowledge gaps, and generation of new experimentally testable hypotheses...

PURPOSE: Regadenoson, an A2A adenosine receptor pharmacologic stress agent for radionuclide myocardial perfusion imaging (MPI), is administered as a single, fixed dose. We studied the side effect profile of regadenoson combined with two types of low-level exercise, according to body mass index (BMI). METHODS: Three hundred and fifty-six patients (46.1% men, mean age 67.7±10.7 years, range 31-90 years) underwent regadenoson stress testing combined with low-level exercise...

Current chemical markers based quality assessment methods largely fail to reflect intrinsic chemical complexity and multiple mechanisms of action of botanical drugs (BD). The development of novel quality markers is greatly needed. Here we propose bioactive chemical markers (BCM), defined as a group of chemo-markers that exhibit similar pharmacological activities comparable to the whole BD, which can therefore be used to effectively assess the quality of BD. As a proof-of-concept, a BCM-based strategy was developed and applied to Xuesaitong Injection (XST) for assessing the efficacy and consistency of different batches...

REVIEW

Autophagy contributes to the maintenance of intracellular homeostasis in most cells of cardiovascular origin, including cardiomyocytes, endothelial cells, and arterial smooth muscle cells. Mitophagy is an autophagic response that specifically targets damaged, and hence potentially cytotoxic, mitochondria. As these organelles occupy a critical position in the bioenergetics of the cardiovascular system, mitophagy is particularly important for cardiovascular homeostasis in health and disease. Consistent with this notion, genetic defects in autophagy or mitophagy have been shown to exacerbate the propensity of laboratory animals to spontaneously develop cardiodegenerative disorders...

The authors review current advances in the therapy of diabetic neuropathy. The role of glycaemic control and management of cardiovascular risk factors in the prevention and treatment of neuropathic complications are discussed. As further options of pathogenetic ally oriented treatment, recent knowledge on benfotiamine and alpha-lipoic acid is comprehensively reviewed. Alpha-lipoic acid is a powerful antioxidant and clinical trials have proven its efficacy in ameliorating neuropathic signs and symptoms. Benfotiamine acts via the activation of transketolase and thereby inhibits alternative pathways triggered by uncontrolled glucose influx in the cells comprising polyol, hexosamine, protein-kinase-C pathways and formation of advanced glycation end products...

Erectile dysfunction (ED), a frequent complaint in the primary care setting, is strongly associated with obesity, cigarette smoking and other common cardiovascular risk factors like hypertension, diabetes mellitus (DM), lipid disorders and the metabolic syndrome. The prevalence of these cardiovascular disorders is rising at staggering rates in most Latin American countries. ED is a symptom that mainly affects economically productive men (40-70 years of age) potentially causing major psychosocial repercussions and reduced quality of life...

BACKGROUND: Despite improvements in the management of severely injured patients, development of multiple organ dysfunction syndrome (MODS) remains a morbid complication of traumatic shock. One of the key attributes of MODS is a profound bioenergetics crisis, for which the mediators and mechanisms are poorly understood. We hypothesized that metabolic uncoupling using an experimental PI3-kinase inhibitor, LY294002 (LY), may prevent mitochondrial abnormalities that lead to the generation of mitochondrial DNA (mtDNA) damage and the release of mtDNA damage associated molecular patterns (DAMPs) METHODS: 16 swine were studied using LY294002 (LY), a non-selective PI3-KI: Animals were assigned to Trauma only (TO, N=3); LY drug only (LYO, N=3); and Experimental (N=10), trauma + drug (LY+T) groups...

Background Loss-of-function variants in the angiopoietin-like 3 gene (ANGPTL3) have been associated with decreased plasma levels of triglycerides, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol. It is not known whether such variants or therapeutic antagonism of ANGPTL3 are associated with a reduced risk of atherosclerotic cardiovascular disease. Methods We sequenced the exons of ANGPTL3 in 58,335 participants in the DiscovEHR human genetics study. We performed tests of association for loss-of-function variants in ANGPTL3 with lipid levels and with coronary artery disease in 13,102 case patients and 40,430 controls from the DiscovEHR study, with follow-up studies involving 23,317 case patients and 107,166 controls from four population studies...

: There is a long-lasting controversy surrounding an association between Abacavir (ABC) and an increased risk of cardiovascular (CV) disease in HIV-positive subjects. While differing in their specifics, a number of published cohort studies and clinical trials support such an association, usually relating it to recent exposure to the drug, independently of traditional predisposing factors. However, other clinical trials have failed to reveal such a relation, and have pointed to methodological differences to explain discrepancies...

AIMS: Many progressive neurological disorders, including Alzheimer's, Huntington's, and Parkinson's diseases, are characterized by accumulation of insoluble protein aggregates. In prospective trials, the cyclooxygenase inhibitor aspirin (acetylsalicylic acid) reduced the risk of Alzheimer's and Parkinson's diseases, as well as cardiovascular events and many late-onset cancers. In view of previous evidence that inflammation promotes protein hyperphosphorylation and aggregation in neurodegenerative diseases, we asked whether aspirin's known ability to block phosphorylation may be secondary to its acetylation of protein targets...

The optimal treatment approach to patients with coronary artery disease (CAD), including those with type 2 diabetes mellitus (T2DM), has been extensively evaluated. Several trials of stable ischemic heart disease including patients with T2DM have demonstrated that medical management is comparable to revascularization in terms of mortality and rates of major adverse cardiovascular events (MACE). There has been a growing appreciation for optimal medical therapy's (OMT) role in improving clinical outcomes. It is vital to target T2DM patients to prevent or delay MACE events through advanced OMT, ultimately delaying if not avoiding the need for revascularization...

Psoriatic arthritis (PsA) is an inflammatory rheumatism belonging to spondylarthritis family and which occurs in about 30% of patients with psoriasis. The pathogenesis entails a genetic predisposition, environmental and immunologic factors. Most of the time, cutaneous lesions precede apparition of articular manifestations and dermatologists who treat psoriatic patients have to regularly screen for early PsA, especially in patients with risk factors (notably nail psoriasis). Early detection greatly increases the chances for successful treatment and can prevent slow joint destruction...

Orexins peptides exert a prominent role in arousal-related processes including stress responding, by activating orexin-1 (OX1R) and orexin-2 (OX2R) receptors located widely throughout the brain. Stress or orexin administration stimulates hyperarousal, adrenocorticotropic hormone (ACTH) and corticosterone release, and selective OX1R blockade can attenuate several stress-induced behavioral and cardiovascular responses but not the hypothalamic-pituitary-adrenal (HPA) axis activation. As opposed to OX1R, OX2R are preferentially expressed in the paraventricular hypothalamic nucleus which is involved in the HPA axis regulation...

Christopher J Gordon
The laboratory mouse has become the predominant test species in biomedical research. The number of papers that translate or extrapolate data from mouse to human has grown exponentially since the year 2000. There are many physiological and anatomical factors to consider in the process of extrapolating data from one species to another. Body temperature is, of course, a critical determinant in extrapolation because it has a direct impact on metabolism, cardiovascular function, drug efficacy, pharmacokinetics of toxins and drugs, and many other effects...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...

Over the past decade, there has been a major shift in chemotherapy from non-specific cytotoxic drugs to molecular targeted drug therapies. As more molecular targeted therapies are developed, new types of cardiovascular toxicities induced by targeted therapies are a growing problem. Cardiotoxicity induced by the human epidermal growth factor receptor-2 inhibitor trastuzumab manifests as decreased left ventricular ejection fraction. In contrast to anthracycline treatment, most cardiac events occur during trastuzumab treatment, but are reversed quickly when treatment is interrupted and cardiac intervention is established...

Preeclampsia has been linked to high morbidity and mortality during pregnancy. However, no efficient pharmacological options for the prevention of this condition are currently available. Preeclampsia is thought to share several pathophysiologic mechanisms with cardiovascular disease, which has led to investigations for the potential role of statins (HMG CoA reductase inhibitors) in its prevention and early management. Pravastatin seems to have a safer pharmacokinetic profile compared to other statins, however, the existing preclinical evidence for its effectiveness in preeclampsia treatment has been mostly restricted to animal models...
