OBJECTIVE: To use Linear Programming (LP) analyses to adapt New Complementary Feeding Guidelines (NCFg) designed for infants aged 6-12 month (m) living in poor socioeconomic circumstances in Bogota to ensure dietary adequacy for young children aged 12-23 m. DESIGN: A secondary data analysis was performed using dietary and anthropometric data collected from 12 m old infants (n = 72) participating in a randomised controlled trial. LP analyses were performed to identify nutrients whose requirements were difficult to achieve using local foods as consumed; and to test and compare the NCFg and alternative food-based recommendations (FBRs) on the basis of dietary adequacy, for 11 micronutrients, at the population level...

OBJECTIVE: Niacin has been used for seven decades to modulate plasma lipids, but its mechanism of action is still unclear. We sought to determine whether variants in the niacin receptor gene, hydroxyl-carboxylic receptor 2 (HCAR2), are associated with lipid response to treatment. PARTICIPANTS AND METHODS: Coding variants, rs7314976 (p.R311C) and rs2454727 (p.M317I), were genotyped in 2067 participants from the Atherothrombosis Intervention in Metabolic Syndrome with Low HDL/High Triglycerides and Impact on Global Health Outcomes (AIM-HIGH) trial...

Hyperglycaemia is a key factor for the formation of advanced glycated endproducts (AGEs). Inhibition of glycation may play key role in minimizing the diabetes related complications. We have tried to explore the glucose and methyl glyoxal mediated glycation and antiglycation activity of niacin using human serum albumin as model protein. Protein was incubated with glucose for 28 days at physiological temperature to achieve glycation. Antiglycation activity was evaluated by assessing free lysine, carbonyl content, AGE specific fluorescence...

Statin intolerance is usually defined as the inability of a patient to tolerate statin-treatment due to muscle-related complaints. While randomised trials show that these complaints occure with similar frequency in patients receiving placebo, namely in up to ~5% of the subjects, data from registries as well as clinical experience indicate a much higher frequency of up to ~30%. The lack of standard definition or of a diagnostic marker of statin intolerance confounds the problem. The diagnosis remains subjective based on the symptoms the patient reports...

Impaired niacin sensitivity (NS) is one of the most replicated findings in untreated schizophrenia, and reflects a disturbance of prostaglandin-mediated pathways in association with deregulated arachidonic acid metabolism, pro-inflammatory activation, and vasomotor function. In ultra-high risk individuals (UHR) increased NS was reported recently, pointing towards dynamic alterations of the underlying pathomechanisms in the period preceding psychosis. However, these characteristics are still unresolved in the diverse UHR groups...

Extrusion is a multistep thermal process which has been utilized in a wide spectrum of food preparations. The effect of extrusion processing on the physicochemical, nutritional, and functional properties of Tarom cultivar rice bran was studied. However, the color of rice bran was improved by extrusion processing, but the protein content was reduced in the stabilized rice bran, which can be related to the denaturation of protein. Extrusion had also a reduction significant effect on the phytic acid as well as vitamin E in rice bran...

PURPOSE OF REVIEW: This article provides an update on the clinical presentation and management of neurologic disease related to key nutrient deficiencies. RECENT FINDINGS: Major advances have been made in understanding the pathway related to vitamin B12 absorption and distribution. It is now known that deficiencies of vitamin B12 and copper have similar neurologic manifestations. Bariatric surgery is a risk factor for both. Alcoholism is just one of the many causes of thiamine deficiency...

Emerging data suggest that the genetic regulation of the biological response to inflammatory stress may be fundamentally different to the genetic underpinning of the homeostatic control (resting state) of the same biological measures. In this paper, we interrogate this hypothesis using a single-SNP score test and a novel class-level testing strategy to characterize protein-coding gene and regulatory element-level associations with longitudinal biomarker trajectories in response to stimulus. Using the proposed class-level association score statistic for longitudinal data, which accounts for correlations induced by linkage disequilibrium, the genetic underpinnings of evoked dynamic changes in repeatedly measured biomarkers are investigated...

Nicotinic acid and nicotinamide are soluble compounds of the vitamin B group, widely used to regulate the lipid profile in hyperlipidemic individuals. Higher doses of nicotinic acid are associated with adverse effects, especially flushing. A unique tolerable upper intake level (UL) of nicotinic acid has not been defined. This meta-analysis aims to evaluate adverse effects and their incidence after supplementation with different doses of nicotinic acid and nicotinamide, comparing results with current ULs in Europe and the United States...

Despite characteristic features, psoriasis can mimic other dermatologic conditions, such as seborrheic dermatitis, lichen simplex chronicus, and certain nutritional deficiencies such as pellagra. We present a patient with a longstanding history of severe plaque psoriasis who presented with disfiguring scaly plaques involving greater than 80% body surface area. The patient's disease was minimally responsive to multiple therapies. Repeat punch biopsies demonstrated parakeratosis, psoriasiform hyperplasia, and dilated blood vessels consistent with psoriasis...
