Preoperative nutritional deficiencies: epidemiology and prevalence of nutritional deficiencies among morbidly obese patients, specifying which ones s…
2021
Abstract Micronutrient deficiency is common in obese patients admitted for bariatric surgery, especially, a considerable prevalence of low levels of vitamin D, folic acid, vitamin B1, vitamin B12, vitamin A, vitamin E, zinc, iron, and selenium has been demonstrated. Patients who are candidates for bariatric surgery usually present various factors that cause the appearance of these deficiencies (inappropriate eating behavior, alcohol consumption, chronic subclinical infiammation, several diseases, and medications that can impact the blood levels of micronutrients). This higher prevalence of micronutrient deficiencies in obese people could also promote postoperative complications and postoper…
Haematological deficiencies in patients with recurrent aphthosis
2010
Background Recurrent aphthosis is a common oral ulcerative condition consisting also of a subset of similar ulcers, properly named 'aphthous-like' ulcers (ALU), linked to systemic diseases and among these, to iron, folic acid and vitamin B(12) deficiencies. Objectives The main objectives of this study were: (i) to evaluate the association between recurrent aphthosis and the most common predisposing factors; (ii) to assess the frequency of ALU in recurrent aphthosis; (iii) to verify the efficacy of a replacement therapy in all ALU patients. Methods Thirty-two adults with recurrent aphthosis and 29 otherwise healthy controls were consecutively recruited, interviewed and subjected to haematolo…
Effects of tannin-containing diets on small ruminant meat quality
2010
Tannins are phenolic compounds present in several forages, tree leaves and by-products used for small ruminant feeding in the Mediterranean area. Although the effects of dietary tannins on small ruminant growth performances have been largely studied, only in the last ten years researchers have started to study the effects of tannins on meat quality. Meat from small ruminants given tanniniferous diets is lighter in colour compared to meat from animals given the same diets but in which the effects of tannins have been eliminated by the supplementation of polyethylene glycol. This result has been obtained with tannins from different feeds (carob pulp, acacia leaves or sulla fresh herbage). Rec…
Eating patterns are associated with biomarkers in a selected population of university students and employees.
2011
AbstractThe association between diet and CVD cannot be assigned to a single nutrient, but rather to a set of nutrients and non-nutrients, and eating pattern analyses have become an important tool in investigation of this relationship. Our objective was to investigate eating patterns in relation to nutrient intake and serum concentration of folate, vitamin B12 and TAG in ninety-five healthy adult participants. Dietary information was collected by an FFQ, and eating patterns were obtained by principal components analyses of thirty-three food groups. Three eating patterns were extracted, a sweet eating pattern identified by intakes of cakes, snacks, sugar-sweetened drinks and chocolates; a pru…
Hepatitis C virus co-infection and sexual risk behaviour are associated with a high homocysteine serum level in HIV-infected patients.
2012
BACKGROUND AND AIMS: A better understanding of the relationship of homocysteine with cardiovascular risk factors is needed. The objectives of this study were to assess the serum level of homocysteine in HIV-infected patients and to analyse the possible association of increased levels of the amino acid with cardiovascular risk factors, demographic and clinical characteristics of participants. METHODS: Cross-sectional study carried out as a supplementary task to the usual controls necessary in HIV-infected patients in the outpatient clinic of the Hospital General of Castellon, Spain. For two consecutive visits the demographic, clinical and HIV-related characteristics and blood analyses result…
Vitamin B12 Deficiency in Children after Continent Urinary Diversion by Mainz Pouch Technique
2010
Purpose MAINZ pouch I urinary diversion provides a high-capacity, low-pressure reservoir. The use of terminal ileum can cause a decrease of vitamin B12 levels. Symptoms caused by vitamin B12 deficiency are rare, but some are irreversible, therefore annual check-ups are recommended. In this study the vitamin B12 levels in the above patients were analyzed in retrospect. Material and Methods The ileocecal segment was used for urinary tract reconstruction in > 80 children ≤17 years of age. B12 levels were determined at various time points within up to 21 years after surgery in 63 patients (8 with ileocecal bladder substitution, 55 continent cutaneous diversion). B12 values below 200pg/ml were c…
Haematological deficiencies in patients with recurrent aphthosis

Reproducibility and validity of a food frequency questionnaire among pregnant women in a Mediterranean area
2013
Background: Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against biochemical biomarkers) of a semi-quantitative food frequency questionnaire (FFQ) in pregnant women. Methods: Participants were 740 pregnant women from a population-based birth cohort study in Valencia (INMA Study). We compared nutrient and food intakes from FFQs estimated for two periods of pregnancy (reproducibility), and compared energy-adjusted intake of several carotenoids, folate, vitamin B12, vitamin C and a-tocopherol of the FFQ in the firs…
