REVIEW
Ana SayuriYamagata, Elisa Brietzke, Joshua D Rosenblat, Ron Kakar, Roger S McIntyre
BACKGROUND: Bipolar disorder (BD) is associated with chronic low-grade inflammation, several medical comorbidities and a decreased life expectancy. Metabolic-inflammatory changes have been postulated as one of the main links between BD and medical comorbidity, although there are few studies exploring possible mechanisms underlying this relationship. Therefore, the aims of the current narrative review were 1) synthesize the evidence for metabolic-inflammatory changes that may facilitate the link between medical comorbidity and BD and 2) discuss therapeutic and preventive implications of these pathways...

Charles S Wiysonge, Hazel A Bradley, Jimmy Volmink, Bongani M Mayosi, Lionel H Opie
BACKGROUND: Beta-blockers refer to a mixed group of drugs with diverse pharmacodynamic and pharmacokinetic properties. They have shown long-term beneficial effects on mortality and cardiovascular disease (CVD) when used in people with heart failure or acute myocardial infarction. Beta-blockers were thought to have similar beneficial effects when used as first-line therapy for hypertension. However, the benefit of beta-blockers as first-line therapy for hypertension without compelling indications is controversial...

Lipid droplets (LDs) are intracellular organelles that are found in nearly all cell types, where they serve fundamental roles in lipid metabolism and energy homeostasis. Traditionally considered as simple lipid storage deposits, these dynamic and remarkable organelles have recently been implicated in a number of other cellular functions, ranging from protein storage and degradation to virus replication. Intracellular accumulation of LDs is also a hallmark feature of diverse human diseases including diabetes type II, obesity, hepatosteatosis, cancer, and atherosclerosis...

BACKGROUND: Drug repositioning can reduce the time, costs and risks of drug development by identifying new therapeutic effects for known drugs. It is challenging to reposition drugs as pharmacological data is large and complex. Subnetwork identification has already been used to simplify the visualization and interpretation of biological data, but it has not been applied to drug repositioning so far. In this paper, we fill this gap by proposing a new Physarum-inspired Prize-Collecting Steiner Tree algorithm to identify subnetworks for drug repositioning...

BACKGROUND: Aggressiveness in humans is a hereditary behavioral trait that mobilizes all systems of the body-first of all, the nervous and endocrine systems, and then the respiratory, vascular, muscular, and others-e.g., for the defense of oneself, children, family, shelter, territory, and other possessions as well as personal interests. The level of aggressiveness of a person determines many other characteristics of quality of life and lifespan, acting as a stress factor. Aggressive behavior depends on many parameters such as age, gender, diseases and treatment, diet, and environmental conditions...

Multiple stressors affect developing and adult organisms, thereby partly structuring their phenotypes. Determining how stressors influence health, well-being, and longevity in human and nonhuman primate populations are major foci within biological anthropology. Although much effort has been devoted to examining responses to multiple environmental and sociocultural stressors, no holistic metric to measure stress-related physiological dysfunction has been widely applied within biological anthropology. Researchers from disciplines outside anthropology are using allostatic load indices (ALIs) to estimate such dysregulation and examine life-long outcomes of stressor exposures, including morbidity and mortality...

Heart failure remains a frequent cause of death and is the leading reason for hospitalization in Germany although therapeutic options have significantly increased over the past years particularly in heart failure with reduced ejection fraction. Clinical symptoms are usually preceded by cardiac remodeling, which was originally defined only by left ventricular dilatation and depressed function but is also associated with typical cellular and molecular processes. Healing after acute myocardial infarction is characterized by inflammation, cellular migration and scar formation...

BACKGROUND: Medical practice variation refers to differences in health service utilization among regions in the same country. It is used as a tool for studying health inequities. In 2011, the OECD launched a Medical Practice Variation Project which examines regional differences within countries and explores the sources of the inter-regional differences. The aim of this study is to examine the patterns and trends in geographic variation for selected health services in Israel. METHODS: The analysis is based on data from the National Hospital Discharges Database (NHDD) of the Israeli Ministry of Health...

Recent studies in animal systems have shown that NO can interact with fatty acids to generate nitro-fatty acids (NO2-FAs). They are the product of the reaction between reactive nitrogen species and unsaturated fatty acids, and are considered novel mediators of cell signaling based mainly on a proven anti-inflammatory response. Although these signaling mediators have been described widely in animal systems, NO2-FAs have scarcely been studied in plants. Preliminary data have revealed the endogenous presence of free and protein-adducted NO2-FAs in extra-virgin olive oil (EVOO), which appear to be contributing to the cardiovascular benefits associated with the Mediterranean diet...

BACKGROUND: The cardiovascular risk of angiogenesis inhibitors is not well-quantified. We hypothesized that, compared to direct vascular endothelial growth factor (VEGF) inhibitors (anti-VEGF antibodies or decoy receptors), small molecule agents have higher risk due to their less specific mechanism. METHODS: We searched the MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials for phase III randomised controlled trials comparing angiogenesis inhibitor-based therapy to other systemic therapy...

The redox co-factor tetrahydrobiopterin (BH4) regulates nitric oxide (NO) and reactive oxygen species (ROS) production by endothelial NOS (eNOS) and is an important redox-dependent signalling molecule in the endothelium. Loss of endothelial BH4 is observed in cardiovascular disease (CVD) states and results in decreased NO and increased superoxide (O2(-)) generation via eNOS uncoupling. Genetic mouse models of augmented endothelial BH4 synthesis have shown proof of concept that endothelial BH4 can alter CVD pathogenesis...

Numerous epidemiological studies have demonstrated a close and bidirectional association between depression and cardiovascular disorders (CVD). This comorbidity places a significant burden on individuals and the healthcare system. Not surprisingly, in the last two decades preclinical research in the field of depression and CVD has rapidly progressed. Multiple studies have demonstrated that aspects of human depression/cardiovascular comorbidity can be modeled in rodents exposed to chronic stress paradigms and that a depressive-like syndrome can be induced in rodent models of CVD...

OBJECTIVES: This study sought to explore the impact of balloon post-dilation (BPD) on outcomes in the CoreValve US Clinical Trials. BACKGROUND: BPD following transcatheter aortic valve replacement (TAVR) has been used in selected cases to optimize hemodynamic results. METHODS: Procedural details of 3,532 patients were examined to determine whether BPD was performed after self-expanding TAVR. "Best practice" guidelines recommended BPD for treatment of suboptimal intraprocedural valve function, primarily manifested by moderate or severe residual aortic regurgitation (AR)...

Estrogen has an impact on the type of lipoproteins and the blood lipid levels, thus protecting the cardiovascular system. Postmenopausal breast cancer patients suffer a significant decrease in estrogen levels due to both physiological changes and the use of drugs, and thus have a higher risk of atherosclerotic cardiovascular diseases. Therefore, strict lipid management is required for postmenopausal breast cancer patients receiving endocrine therapy. However, no guidelines have been developed in terms of lipid management and intervention for postmenopausal breast cancer patients...

BACKGROUND: Healthcare systems have difficulty incorporating scientific evidence into clinical practice, especially when science suggests that existing clinical practices are of low-value (e.g. ineffective or harmful to patients). While a number of lists outlining low-value practices in acute care medicine currently exist, less is known about how best to initiate and sustain the removal of low-value clinical practices (i.e. de-adoption). This study will develop a comprehensive list of barriers and facilitators to the de-adoption of low-value clinical practices in acute care facilities to inform the development of a framework to guide the de-adoption process...
