SCARB1 rs5888 gene polymorphisms in coronary heart disease: A systematic review and a meta-analysis.
Ma, R, Zhu, X, Yan, B
Gene. 2018;:280-287
Abstract
BACKGROUND Studies have suggested that high-density lipoprotein (HDL) stimulates scavenger receptor class B type 1 (SR-B1) to promote hepatic uptake of cholesterol. SR-B1 is encoded by scavenger receptor class B member 1 (SCARB1) gene in human. A rare mutation in SCARB1 gene has been associated with coronary heart disease (CHD). A polymorphism rs5888 of SCARB1 gene has been linked to CHD risk in humans. OBJECTIVES The objective was to investigate the relationship between the SCARB1 gene polymorphism rs5888 and risk of CHD. METHODS We searched databases of case-control studies and cohort studies on rs5888 polymorphism of SCARB1 gene and risk of CHD. Two reviewers independently screened literature, extracted data, and estimated potential bias of included studies. The quality of the studies was evaluated by recommendation of Newcastle-Ottawa Scale (NOS). Meta-analysis was performed with Stata 12.0 software. RESULTS Seven studies including 6360 subjects (cases: 2456, controls: 3904) were included in the final data combination. Meta-analysis showed T allele had a lower risk of CHD as compared to C allele in allele model (T vs. C: OR = 0.87, 95% CI: 0.70 to 1.09, P = 0.229). Moreover, we found that T allele or TT/TC had a lower risk of CHD as compared to C/CC in male in allele model (T vs. C: OR = 0.79, 95% CI: 0.61 to 1.01). However, no significant association was observed in women in all allele models. CONCLUSIONS Our findings suggested that polymorphism rs5888 had negative association with CHD, especially in male. However, the conclusion needs further verification with high quality studies with larger sample size and rigorous designs.

Abstract
The Multimorbid Patient: Use of New Oral Anticoagulants in Patients with Chronic Kidney Disease Abstract. Increasing life expectancy in Western countries is associated with a high prevalence of multiple chronic diseases which is defined by the term "multimorbidity". Many of these patients suffer from chronic kidney disease (CKD) and thrombogenic comorbidities such as atrial fibrillation with the need for oral anticoagulation. For decades vitamin K antagonists have been exclusively prescribed for oral anticoagulation. However, due to altered pharmacokinetics and bioavailability of these drugs in CKD, a significant risk of bleeding exists. The introduction of direct oral anticoagulants as a new and promising alternative to vitamin K antagonists was -especially for CKD patients - highly anticipated. However, data from randomized studies are missing for older patients with advanced CKD. Consequently, a careful evaluation of the risk-benefit ratio is recommended for this sensitive patient population.

Traina, MI, Almahmeed, W, Edris, A, Murat Tuzcu, E
Current atherosclerosis reports. 2017;(5):24
Abstract
PURPOSE OF REVIEW The Middle East and North Africa has witnessed a dramatic transformation over the last 30 years caused by rapid urbanization and modernization and significant changes to diet and lifestyle. This review attempts to highlight recent data in regards to ischemic heart disease and its risk factors from the region. RECENT FINDINGS Ischemic heart disease is now the leading cause of death in the region. Age at presentation with myocardial infarction and acute coronary syndrome appears to be significantly younger than global averages. Increased rates of all major risk factors including diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle have been noted. Specifically, significant changes to dietary habits and growing epidemic of use of alternative tobacco products are noted. This review article highlights the growing epidemic of ischemic heart disease in the region led by dramatic increases in incidence of its risk factors. This epidemic will require a multipronged approach to address the varied issues and mitigate the growing prevalence of the disease.

Effects of Olive Oil Phenolic Compounds on Inflammation in the Prevention and Treatment of Coronary Artery Disease.
Souza, PAL, Marcadenti, A, Portal, VL
Nutrients. 2017;(10)
Abstract
Coronary artery disease (CAD) is responsible for more than 7 million deaths worldwide. In the early stages of the development of atherosclerotic plaques, cardiovascular risk factors stimulate vascular endothelial cells, initiating an inflammatory process, fundamental in the pathogenesis of CAD. The inclusion of potentially cardioprotective foods, such as olive oil, to the diet, may aid in the control of these risk factors, and in the reduction of cytokines and inflammatory markers. The present review aims to address the interaction between phenolic compounds present in olive oil, and inflammation, in the prevention and treatment of CAD. In vitro and in vivo studies suggest that phenolic compounds, such as hydroxytyrosol, tyrosol, and their secoiridoid derivatives, may reduce the expression of adhesion molecules and consequent migration of immune cells, modify the signaling cascade and the transcription network (blocking the signal and expression of the nuclear factor kappa B), inhibit the action of enzymes responsible for the production of eicosanoids, and consequently, decrease circulating levels of inflammatory markers. Daily consumption of olive oil seems to modulate cytokines and inflammatory markers related to CAD in individuals at risk for cardiovascular diseases. However, clinical studies that have evaluated the effects of olive oil and its phenolic compounds on individuals with CAD are still scarce.

Abstract
OBJECTIVE To conduct meta-analyses of randomized controlled trials (RCTs) to estimate the effect of eicosapentaenoic and docosahexaenoic acid (EPA+DHA) on coronary heart disease (CHD), and to conduct meta-analyses of prospective cohort studies to estimate the association between EPA+DHA intake and CHD risk. METHODS A systematic literature search of Ovid/Medline, PubMed, Embase, and the Cochrane Library from January 1, 1947, to November 2, 2015, was conducted; 18 RCTs and 16 prospective cohort studies examining EPA+DHA from foods or supplements and CHD, including myocardial infarction, sudden cardiac death, coronary death, and angina, were identified. Random-effects meta-analysis models were used to generate summary relative risk estimates (SRREs) and 95% CIs. Heterogeneity was examined in subgroup and sensitivity analyses and by meta-regression. Dose-response was evaluated in stratified dose or intake analyses. Publication bias assessments were performed. RESULTS Among RCTs, there was a nonstatistically significant reduction in CHD risk with EPA+DHA provision (SRRE=0.94; 95% CI, 0.85-1.05). Subgroup analyses of data from RCTs indicated a statistically significant CHD risk reduction with EPA+DHA provision among higher-risk populations, including participants with elevated triglyceride levels (SRRE=0.84; 95% CI, 0.72-0.98) and elevated low-density lipoprotein cholesterol (SRRE=0.86; 95% CI, 0.76-0.98). Meta-analysis of data from prospective cohort studies resulted in a statistically significant SRRE of 0.82 (95% CI, 0.74-0.92) for higher intakes of EPA+DHA and risk of any CHD event. CONCLUSION Results indicate that EPA+DHA may be associated with reducing CHD risk, with a greater benefit observed among higher-risk populations in RCTs.

Muhammad, JS, Zaidi, SF, Saeed, SA, Ishaq, M
JPMA. The Journal of the Pakistan Medical Association. 2017;(6):907-911
Abstract
Helicobacter pylori infection is considered the most commonly prevalent gastrointestinal pathogen where it manages to survive despite the hostile environment of human stomach, leading to various gastric diseases including gastric cancer. Due to the chronic inflammatory state induced by H. pylori and its interaction with host immune system have diverted researchers to investigate its correlation with systemic diseases outside of the gastrointestinal tract. This literature review was done to explore the association of H. pylori infection with haematological and cardiovascular diseases. We used medical subject heading (MeSH) terms "Helicobacter pylori" with "inflammation," "haematological diseases," "coronary heart diseases" or "vascular diseases" to search PubMed database. All relevant studies identified from 2005 to 2015 were included. As many of the studies are small-scale or showed weak association, further studies are needed to address the role of H. pylori in pathogenesis of haematological and cardiovascular diseases.

Abstract
The FINRISK risk calculator predicts 10-year risk for coronary heart disease, stroke incidence, and their combination. The model is based on 10-year cohort follow-up from 3 different cohorts in 1982, 1987, and 1992 from a random population sample in 3 areas in Finland. Coronary heart disease, stroke, and their combination are predicted by smoking, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, diabetes, and family history. The Internet-based calculator is commonly used in Finland in health services to assess the need for hypertension and hypercholesterolemia treatment and is used also in patients' counseling.

Alexander, DD, Miller, PE, Vargas, AJ, Weed, DL, Cohen, SS
Journal of the American College of Nutrition. 2016;(8):704-716
Abstract
The possible relationship between dietary cholesterol and cardiac outcomes has been scrutinized for decades. However, recent reviews of the literature have suggested that dietary cholesterol is not a nutrient of concern. Thus, we conducted a meta-analysis of egg intake (a significant contributor to dietary cholesterol) and risk of coronary heart disease (CHD) and stroke. A comprehensive literature search was conducted through August 2015 to identify prospective cohort studies that reported risk estimates for egg consumption in association with CHD or stroke. Random-effects meta-analysis was used to generate summary relative risk estimates (SRREs) for high vs low intake and stratified intake dose-response analyses. Heterogeneity was examined in subgroups where sensitivity and meta regression analyses were conducted based on increasing egg intake. A 12% decreased risk (SRRE = 0.88, 95% confidence interval [CI], 0.81-0.97) of stroke was observed in the meta-analysis of 7 studies of egg intake (high vs low; generally 1/d vs <2/wk), with little heterogeneity (p-H = 0.37, I2 = 7.50). A nonstatistically significant SRRE of 0.97 (95% CI, 0.88-1.07, p-H = 0.67, I2 = 0.00) was observed in the meta-analysis of 7 studies of egg consumption and CHD. No clear dose-response trends were apparent in the stratified intake meta-analyses or the meta regression analyses. Based on the results of this meta-analysis, consumption of up to one egg daily may contribute to a decreased risk of total stroke, and daily egg intake does not appear to be associated with risk of CHD. Key Teaching Points: • The role of egg consumption in the risk of stroke and coronary heart disease has come under scrutiny over many years. • A comprehensive meta-analysis of prospective cohort studies that reported risk estimates for egg consumption in association with CHD or stroke was performed on the peer-reviewed epidemiologic literature through August 2015. • Overall, summary associations indicate that intake of up to 1 egg daily may be associated with reduced risk of total stroke. • Overall, summary associations show no clear association between egg intake and increased or decreased risk of CHD. • Eggs are a relatively low-cost and nutrient-dense whole food that provides a valuable source of protein, essential fatty acids, antioxidants, choline, vitamins, and minerals.

New data on harmful effects of trans-fatty acids.
Ginter, E, Simko, V
Bratislavske lekarske listy. 2016;(5):251-3
Abstract
Various margarines containing trans-fatty acids were marketed as being healthier because of the absence of cholesterol, suggesting to use margarine instead of butter. Fifteen years ago, research documented the grave health risk of trans-fats (T-fat). US FDA in 2015 finalized its decision that T-fat is not safe and set a three-year time limit for complete removal of T-fat from all foods. The greatest danger from T-fat lies in its capacity to distort the cell membranes. The primary health risk identified for T-fat consumption is an elevated risk of coronary heart disease. T-fats have an adverse effect on the brain and nervous system. T-fat from the diet is incorporated into brain cell membranes and alter the ability of neurons to communicate. This can diminish mental performance. Relationship between T-fat intake and depression risk was observed. There is growing evidence for a possible role of T-fat in the development of Alzheimer´s disease and cognitive decline with age.
