REVIEW
Soo-Sang Kang, Robert S Rosenson
Homocysteine is an intermediary metabolite in the methionine cycle. Accumulation of homocysteine is caused either by mutation of relevant genes or by nutritional depletion of related vitamin(s). This review covers the historical background of hyperhomocysteinemia in which indispensable subjects in relation to underlying pathophysiological processes are discussed with the view of metabolism and genetics of folate and methionine cycles. This review emphasizes the unique role of homocysteine that is clearly distinct from other risk factors, particularly cholesterol in the development of vascular disease...

Nutritional status could affect arsenic metabolism and toxicity in the general population chronically exposed to low levels of inorganic arsenic. In this study, we examined the association of serum folate and cobalamin with urinary concentrations of dimethylarsinic acid (DMA), the most abundant metabolite of inorganic arsenic measured in urine, in children and adults who participated in the 2003-2006 US National Health and Nutrition Examination Surveys. A total of 1161 children (aged 6-19 years) and 1938 adults (aged 20-85 years) were analyzed for the association using multivariate general linear models, adjusting for potential confounders...

The UK currently has the most detailed, directly measured data for food wasted in the home. This includes information on the exact types of food wasted. These data allow calculation of the nutrients within that waste, as well as its environmental impact. The results progress the conversation beyond how much food is wasted or its energy content; it permits the implications for nutrition and sustainability to be assessed in detail. Data for UK household food waste were expressed as an average waste per capita for each type of food...

"Anemias beyond iron, vitamin B12, and folate deficiencies" covers a wide array of everything which lies beyond commonly seen anemias caused by deficiencies of three micronutrients. Although anemias due to deficiencies of iron, B12, and folate are common in daily practice and account for at least one-third of anemia etiologies in older adults, it is not uncommon to encounter other nutritional and toxin-induced underproduction anemias. The combination of thorough clinical examination, careful peripheral blood smear review, and judicious selection of supporting laboratory studies is typically sufficient to make an assertive diagnosis of those cases...

Background: Epidemiologic and in vitro studies suggest independent linkages between poor folate and/or vitamin B-12 nutrition, genomic human papillomavirus (HPV) type 16 viral integration, and cancer. However, there is no direct evidence in vivo to support the causative role of poor folate nutrition in HPV16 integration into the cellular genome. Objective: We tested the hypothesis that folate deficiency enables the integration of HPV16 into the genome of HPV16-harboring keratinocytes, and could thereby influence earlier transformation of these cells to cancer in an animal model...

Homocysteine (Hcy) is thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of the folic acid, vitamins B6 and B12. Consequently, the level of the total Hcy in the serum is influenced by the presence or absence of these vitamins. An elevated level of the Hcy, hyperhomocysteinemia (HHcy) and homocystinuria are connected with occlusive artery disease, especially in the brain, the heart, and the kidney, in addition to venous thrombosis, chronic renal failure, megaloblastic anemia, osteoporosis, depression, Alzheimer's disease, pregnancy problems, and others...

The fetal origins of health and disease framework has identified extremes in fetal growth and birth weight as factors associated with the lifelong generation of chronic diseases such as obesity, diabetes, cardiovascular disease, and hypertension. Maternal nutrition plays a critical role in fetal and placental development, in part by providing the methyl groups required to establish the fetus's genome structure and function, notably through DNA methylation. The goal of this narrative review is to describe the role of maternal dietary methyl donor (methionine, folate, and choline) and cofactor (zinc and vitamins B2, B6, and B12) intake in one-carbon metabolism and DNA methylation in the fetus and placenta, as well as their impacts on fetal growth and lifelong health outcomes, with specific examples in animals and humans...

Background: Patients with cancer are highly concerned about food choices and dietary supplements that may affect their treatment outcomes. Excess folic acid (synthetic folate) from supplements or fortification can lead to accumulation of unmetabolized folic acid in the systemic circulation and urine and may promote cancer growth, especially among those with neoplastic alterations. Objective: We investigated the prospective association between synthetic compared with natural folate intake and clinical outcomes in non-muscle-invasive bladder cancer (NMIBC), which is a highly recurrent disease...

OBJECTIVE: Iron deficiency (ID) is the most common nutritional deficiency, and iron metabolism becomes further deteriorated in the presence of certain conditions, such as heart failure (HF). Atrial fibrillation (AF) has many similarities to HF, including a chronic inflammatory pathophysiology; however, the prevalence of ID and other hematinic deficiencies in AF patients have not been determined. METHODS: In this study, the prevalence of iron (serum ferritin <100 µg/L or ferritin 100-299 µg/L with transferrin saturation <20%), vitamin B12 (<200 pg/mL), and folate deficiency (<4...

BACKGROUND & AIMS: Vegetarians and vegans are more vulnerable to vitamin B12 deficiency with severe risks of megaloblastic anemia, cognitive decline, neuropathy, and depression. An easy and simple method of supplementation consists of taking one weekly dosage of 2000 μg. However, single large oral doses of vitamin B12 are poorly absorbed. The present research evaluates the ability of two different sublingual dosages of vitamin B12 (350 μg/week vs 2000 μg/week) in improving cyanocobalamin (vitamin B12 ) nutritional status in vegans and vegetarians with a marginal deficiency...
