BACKGROUND: Metabolic syndrome (MS) is a well-known risk factor for the development of cardiovascular (CV) disease; yet, controversy persists whether it adds incremental prognostic value in patients with established CV disease. OBJECTIVES: This study was performed to determine if MS is associated with worse CV outcomes in patients with established CV disease treated intensively with statins. METHODS: We performed a post hoc analysis of the Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes trial, in which patients with established CV disease and atherogenic dyslipidemia (n = 3414) were randomly assigned to receive extended release niacin or placebo during a mean 36-month follow-up, to assess whether the presence of MS or the number of MS components contributed to CV outcomes...

INTRODUCTION AND AIM: The Hungarian Diet and Nutritional Status Survey was implemented on a sub-sample of the European Health Interview Survey. In this paper, the authors present the data on the vitamin intake of the Hungarian population. METHOD: The survey represents the vitamin intake of the Hungarian non-institutionalised adult population of 18 years and older. There are significant differences between men's and women's vitamin intake. RESULTS: The intake of all water-soluble vitamins except for vitamin C is higher in men than in women, and the difference between the genders regarding the intake of vitamin E and D is significant...

BACKGROUND: Congenital malformations can be manifested as combinations of phenotypes that co-occur more often than expected by chance. In many such cases, it has proved difficult to identify a genetic cause. We sought the genetic cause of cardiac, vertebral, and renal defects, among others, in unrelated patients. METHODS: We used genomic sequencing to identify potentially pathogenic gene variants in families in which a person had multiple congenital malformations...

Paclitaxel is a member of the taxane agents that has demonstrated efficacy in ovarian cancer, both in first- and in second-line therapy. Counted among the side-effects of this drug are neurological disorders. In the present study, a rare case of a non-neuropathic ocular disorder, known as cystoid macular edema (CME), due to paclitaxel in patients treated for ovarian cancer is described. Macular edema, or CME, is a common cause of visual impairment that has been classically demonstrated by fluorescein angiograms, showing capillary leakage...

Butyrate and niacin are produced by gut microbiota, however butyrate has received most attention for its effects on colonic health. The present study aimed at exploring the effect of niacin on experimental colitis as well as throwing some light on the ability of niacin to modulate angiogenesis which plays a crucial role of in the pathogenesis of inflammatory bowel disease. Rats were given niacin for 2 weeks. On day 8, colitis was induced by intrarectal administration of iodoacetamide. Rats were sacrificed on day 15 and colonic damage was assessed macroscopically and histologically...

A key to effective treatment of cardiovascular disease is to understand the body's complex lipoprotein transport system. Reverse cholesterol transport (RCT) is the process of cholesterol movement from the extrahepatic tissues back to the liver. Lipoproteins containing apoA-I [highdensity lipoprotein (HDL)] are key mediators in RCT, whereas non-high-density lipoproteins (non-HDL, lipoproteins containing apoB) are involved in the lipid delivery pathway. HDL particles are heterogeneous; they differ in proportion of proteins and lipids, size, shape, and charge...

Colorectal cancer is one of the global causes of cancer deaths. Cancer stem cells (CSCs) inside the tumour niche responsible for metastasis and relapses, and hence need to be targeted for cancer therapeutics. Although dietary fibre and lifestyle changes have been recommended as measures for colorectal cancer prevention, no such recommendations are available for using water soluble vitamins as prophylaxis measure for colorectal cancers. High dose of Vitamin C has been proven to selectively kill colon cancer cells having BRAF and KRAS mutations by inducing oxidative stress...

Small molecule inhibitors of adipocyte fatty acid binding protein 4 (FABP4) have attracted interest following the recent publications of beneficial pharmacological effects of these compounds. FABP4 is predominantly expressed in macrophages and adipose tissue where it regulates fatty acids (FAs) storage and lipolysis and is an important mediator of inflammation. In the past years, hundreds FABP4 inhibitors have been synthesized for effective atherosclerosis and diabetes treatments, including derivatives of niacin, quinoxaline, aryl-quinoline, bicyclic pyridine, urea, aromatic compounds and other novel heterocyclic compounds...

BACKGROUND: Pellagra, which is caused by a deficiency of niacin and tryptophan, the precursor of niacin, is a rare disease in developed countries where alcoholism is a major risk factor due to malnutrition and lack of B vitamins. Although pellagra involves treatable dementia and psychosis, it is often underdiagnosed, especially in developed countries. CASE REPORT: In Japan, a 37-year-old man presented to the emergency department with altered mental status and seizures...

Long-distance transportation is sometimes inevitable in the beef industry because of the geographic separation of major breeding and fattening areas. Long-distance transportation negatively impacts production and health of cattle, which may, at least partly, result from the disturbance of metabolism during and after transportation. However, alteration of metabolism remains elusive in transported cattle. We investigated the effects of transportation on the metabolomic profiles of Holstein steer calves. Non-targeted analysis of serum concentrations of low molecular weight metabolites was performed by gas chromatography mass spectrometry...

REVIEW
Angela Pirillo, Alberico L Catapano
Low high density lipoprotein cholesterol (HDL-C) levels represent an independent risk factor for cardiovascular disease; in addition to the reduced HDL-C levels commonly observed in patients at cardiovascular risk, the presence of dysfunctional HDL, i.e. HDL with reduced atheroprotective properties, has been reported. Despite the established inverse correlation between HDL-C levels and cardiovascular risk, several clinical trials with HDL-C-increasing drugs (such as niacin, CETP inhibitors or fibrate) failed to demonstrate that a significant rise in HDL-C levels translate into a cardiovascular benefit...
