    Normal functioning of the human body requires a balance between nutritional intake and metabolism, and imbalances manifest as nutritional deficiencies or excess. Nutritional deficiency states are associated with social factors (war, poverty, famine, and food fads), medical illnesses with malabsorption (such as Crohn disease, cystic fibrosis, and after bariatric surgery), psychiatric illnesses (eating disorders, autism, alcoholism), and medications. Nutritional excess states result from inadvertent or intentional excessive intake. Cutaneous manifestations of nutritional imbalance can herald other systemic manifestations. This contribution discusses nutritional deficiency and excess syndromes with cutaneous manifestations of particular interest to clinical dermatologists. Copyright © 2010. Published by Elsevier Inc.

  3. Zinc: physiology, deficiency, and parenteral nutrition.

    The essential trace element zinc (Zn) has a large number of physiologic roles, in particular being required for growth and functioning of the immune system. Adaptive mechanisms enable the body to maintain normal total body Zn status over a wide range of intakes, but deficiency can occur because of reduced absorption or increased gastrointestinal losses. Deficiency impairs physiologic processes, leading to clinical consequences that include failure to thrive, skin rash, and impaired wound healing. Mild deficiency that is not clinically overt may still cause nonspecific consequences, such as susceptibility to infection and poor growth. The plasma Zn concentration has poor sensitivity and specificity as a test of deficiency. Consequently, diagnosis of deficiency requires a combination of clinical assessment and biochemical tests. Patients receiving parenteral nutrition (PN) are susceptible to Zn deficiency and its consequences. Nutrition support teams should have a strategy for assessing Zn status and optimizing this by appropriate supplementation. Nutrition guidelines recommend generous Zn provision from the start of PN. This review covers the physiology of Zn, the consequences of its deficiency, and the assessment of its status, before discussing its role in PN. © 2015 American Society for Parenteral and Enteral Nutrition.

    Full Text Available Heart failure (HF is the main cause of mortality and morbidity in Western countries. Although evidence-based treatments have substantially improved outcomes, prognosis remains poor with high costs for health care systems. In patients with HF, poor dietary behaviors are associated with unsatisfactory quality of life and adverse outcome. The HF guidelines have not recommended a specific nutritional strategy. Despite the role of micronutrient deficiency, it has been extensively studied, and data about the efficacy of supplementation therapy in HF are not supported by large randomized trials and there is limited evidence regarding the outcomes. The aim of the present review is to analyze the state-of-the-art of nutritional deficiencies in HF, focusing on the physiological role and the prognostic impact of micronutrient supplementation.

    Iodine nutrition is a result of geological conditions, iodine fortification and monitoring strategies within a country together with the dietary habits of the population. This review summarizes the basis for the current iodine situation in the Scandinavian countries in order to identify gaps...... strategies have been used in Scandinavia to improve iodine nutrition. The major source of iodine is iodized salt in Sweden and from milk and dairy products in Norway. In Denmark, drinking water, milk, dairy products and iodized salt used in commercial production of bread are the important sources of iodine....... The current iodine status in Scandinavia is not optimal and action is ongoing to increase iodination in Denmark, where there is mild iodine deficiency in the general population. Data from all three countries indicate insufficient iodine nutrition during pregnancy and there is a need for data from children...

    Parenteral nutrition is crucial for supply of nutrients in children who cannot tolerate a full enteral diet. In the United States, it is not standard of care to give iodine to children dependent on parenteral nutrition, hence iodine is not routinely included in the micronutrient package. Herein, we present a case of a boy with hypothyroidism secondary to iodine deficiency after prolonged exclusive use of parenteral nutrition. Our case highlights the importance of screening for iodine deficiency and administering timely iodine supplementation in these at-risk children to prevent iatrogenic hypothyroidism. © 2015 American Society for Parenteral and Enteral Nutrition.

    Full Text Available OBJECTIVE: To determine the prevalence of nutritional deficiency among patients with pulmonary tuberculosis. METHODS: This was a cross-sectional study using data obtained from the Brazilian Case Registry Database and from the medical records of patients diagnosed with pulmonary tuberculosis (15-59 years of age residing in one of the municipalities that make up the 16th Regional Health District of the state of Bahia. We calculated the incidence, lethality, and mortality rates, as well as the prevalence of nutritional deficiency, as evaluated by body mass index. Demographic, social, clinical, and epidemiological data were collected. RESULTS: Of the 72 confirmed cases of tuberculosis, 59 (81.9% were in males, and 21 (29.2% of the patients were in the 40-49 year age bracket. The majority (85.3% described themselves as Mulatto or Black; 55.2% reported using alcohol; and approximately 90% were treated as outpatients. In the district and age bracket studied, the incidence of pulmonary tuberculosis was 30.6/100,000 population. Among the 72 patients, data regarding nutritional status was available for 34. Of those, 50% and 25%, respectively, presented nutritional deficiency at the beginning and at the end of treatment. No statistically significant differences were found between normal-weight and malnourished patients regarding the characteristics studied. CONCLUSIONS: The prevalence of nutritional deficiency was high among our sample of patients with pulmonary tuberculosis. This underscores the importance of nutritional follow-up for the assessment of tuberculosis treatment in the decision-making process regarding therapeutic interventions.

    Full Text Available Introduction: Adolescents are considered to be a nutritionally vulnerable segment of the population. There is a greater need to look into the nutritional status of adolescents but unfortunately, precise estimates of their dietary intake, dietary practices as well as nutritional deficiencies have been the least explored area. The general objective for conducting this study was to assess the dietary pattern and nutritional deficiencies among adolescents. Materials and Methods: A cross-sectional study was conducted among adolescents in schools and colleges in the urban areas of Jhansi district in Uttar Pradesh. The study sample consisted of 400 school children in the age group of 10-19 years. Food consumption of the subjects was assessed using a 3-day food intake recall method. Results: Mean age of the adolescents was 14.16 years. More than half of the children studied had malnutrition (53.5%. Mean intake of calorie, protein, fat, iron, and vitamins A and C were lower than the Recommended Dietary Allowances (RDAs. The habitual dietary pattern indicated poor consumption of milk, liver, and leafy vegetables. In comparison to boys (31.5%, more girls (46% were underweight. On seeing the association, nutritional status of these adolescents within the normal limits were found to be significantly higher in those from nuclear families (P < 0.001, those with better educated parents (P < 0.000, and those from families of higher socioeconomic status (P < 0.000. Conclusion: Overall, among the participants, there were both macro- and micronutrients deficiencies. Therefore, there is a need to encourage people to adopt small family norms, and a need for the sensitization of both adolescents and their parents through health and nutrition education (HNE to improve the health and nutritional status of the adolescents.

  11. Myeloid Neoplasms in the Guise of Nutritional Deficiency

    2012-01-01

    The classic BCR-ABL-negative myeloproliferative neoplasms (MPNs) which include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are among the most frequent hematologic neoplasms. Because of their relatively smooth clinical course, it is likely that many of these MPNs actually go undetected. Considering the high prevalence of iron, folic-acid, and vitamin B12 deficiencies in developing countries, their coexistence with MPN can be expected frequently. In such situations where both disorders coexist, MPN is often overlooked. This causes considerable diagnostic delay. In this paper, two cases of PMF and one case of PV where the diagnosis of MPN was delayed for about 3 years are discussed. Presence of concomitant vitamin B12, folate, and iron deficiencies perhaps camouflaged the underlying MPN. Bearing in mind the possibility of MPN, even in the setting of apparent nutritional deficiency and performing a bone marrow evaluation, is the crucial step in unveiling the hidden MPN. PMID:23227377

    Iron is not routinely added to parenteral nutrition (PN) formulations in the United States because of the risk of anaphylaxis and concerns about incompatibilities. Studies have shown that iron dextran in non-lipid-containing PN solutions is safe. Data are limited on iron status, prevalence of iron deficiency anemia (IDA), and efficacy of intravenous iron infusion in long-term home PN (HPN). We aimed to determine the incidence of IDA and to examine the effectiveness of parenteral iron replacement in patients receiving HPN. Medical records of patients receiving HPN at the Mayo Clinic from 1977 to 2010 were reviewed. Diagnoses, time to IDA development, and hemoglobin, ferritin, and mean corpuscular volume (MCV) values were extracted. Response of iron indices to intravenous iron replacement was investigated. Of 185 patients (122 women), 60 (32.4%) were iron deficient. Five patients were iron deficient, and 18 had unknown iron status before HPN. Of 93 patients who had sufficient iron storage, 37 had IDA development after a mean of 27.2 months (range, 2-149 months) of therapy. Iron was replaced by adding maintenance iron dextran to PN or by therapeutic iron infusion. Patients with both replacement methods had significant improvement in iron status. With intravenous iron replacement, mean ferritin increased from 10.9 to 107.6 mcg/L (P Parenteral and Enteral Nutrition.

    . In the future, dietary modification/diversification, although long term, may be the preferred strategy because it is more sustainable, economically feasible, culturally acceptable, and equitable, and can be used to alleviate several micronutrient deficiencies simultaneously, without danger of inducing antagonistic micronutrient interactions. Appropriate dietary strategies include consumption of zinc-dense foods and those known to enhance zinc absorption, reducing the phytic acid content of plant based staples via enzymic hydrolysis induced by germination/fermentation or nonenzymic hydrolysis by soaking or thermal processing. All the strategies outlined above should be integrated with ongoing national food, nutrition and health education programmes, to enhance their effectiveness and sustainability, and implemented using nutrition education and social marketing techniques. Ultimately the success of any approach for combating zinc deficiency depends on strong advocacy, top level commitment, a stable infrastructure, long term financial support and the capacity to control quality and monitor and enforce compliance at the national or regional level. To be cost effective, costs for these strategies must be shared by industry, government, donors and consumers.

    Full Text Available Abstract Background The purpose of the study is to determine whether exposure to malnutrition during early life is associated with increased risk of stomach cancer in later life. Methods The design protocol included analyzing the trend of gastric cancer mortality and nutrition and evaluating the association between nutrient deficiency in early life and the risk of gastric cancer by hierarchical age–period–birth cohort (APC analysis using general log-linear Poisson models and to compare the difference between birth cohorts who were exposed to the 1959–1961 Chinese famine and those who were not exposed to the famine. Data on stomach cancer mortality from 1970 to 2009 and the dietary patterns from 1955 to 1985 which included the 1959–1961 Chinese famine period in the Zhaoyuan County population were obtained. The nutrition information was collected 15 years prior to the mortality data as based on the latest reference of disease incubation. Results APC analysis revealed that severe nutrition deficiency during early life may increase the risk of stomach cancer. Compared with the 1960–1964 birth cohort, the risk for stomach cancer in all birth cohorts from 1900 to 1959 significantly increased; compared with the 1970–1974 cohort, the risk for stomach cancer in the 1975–1979 cohort significantly increased, whereas the others had a steadily decreased risk; compared with 85–89 age group in the 2005–2009 death survey, the ORs decreased with younger age and reached significant levels for the 50–54 age group after adjusting the confounding factors. The 1930 to 1964 group (exposed to famine had a higher mortality rate than the 1965 to 1999 group (not exposed to famine. For males, the relative risk (RR was 2.39 and the 95% confidence interval (CI was 1.51 to 3.77. For females, RR was 1.64 and 95% CI was 1.02 to 2.62. Conclusion The results of the present study suggested that prolonged malnutrition during early life may increase the risk of

    Chronic pancreatitis results in exocrine and endocrine dysfunction, affecting normal digestion and absorption of nutrients. In individuals with chronic pancreatitis, nutrition status may be further affected by poor dietary intake, often related to alcoholism. However, some deficiencies may be overlooked, potentially leading to nutrition-related problems with bone health and fatigue. The aim of this article is to describe the deficiencies that occur and to propose an evidence-based algorithm for the nutrition assessment and treatment of patients with chronic pancreatitis.

    Conducting nutrition-focused physical examinations and reporting the findings from the perspective of nutrition status strengthen the practitioner's assessments, interventions, and monitoring. The nutrition-focused physical examination of the oral cavity is particularly useful to identify nutrient deficiencies early and with accuracy as the tissues in the oral mucosa have a turnover rate of nutrition care. The purpose of this article is to discuss the methods of conducting a nutrition-focused oral screening examination and compile and document the evidence regarding the effects of micronutrient deficiencies on the oral mucosa. The information is formatted into a table that can be used as a tool when conducting an oral screening by identifying possible deficiencies based on the observations and other relevant findings. The tool will also guide the practitioner in confirming the physical findings, suggesting interventions to treat the deficiency and how to monitor the outcomes.

    Deficient nutrition is a common pathological factor encountered in medical practice. We evaluated results of combined intake of Essentuki-Novaya mineral water and Nutridrink artificial food mixture (Nutritia, Holland). Spa and resort therapy based on the use of natural factors and well-balanced nutrition resulted in the marked alleviation of clinical symptoms in patients with gastrointestinal disorders. Simultaneously, the consequences of deficient nutrition in the preceding period were corrected and manifestations of the main pathological syndromes decreased. It is concluded that a short-term course of oral alimentation using food substrate mixtures had beneficial effect on the health state of patients by improving their nutritional status and quality of life.

    1996-01-01

    Full Text Available Available evidence suggests that trace elements, such as zinc, once thought to have no nutritional relevance, are possibly deficient in large sections of the human population. Conditioned deficiencies have been reported to result from malabsorption syndromes, acrodermatitis enteropathica, alcoholism, gastrointestinal disease, thermal injury, chronic diseases (eg, diabetes, sickle cell anemia, and in total parenteral nutrition therapy. Awareness that patients with these problems are at risk has led health professionals to focus increasingly on the importance of zinc therapy in the prevention and treatment of deficiency. More recently zinc toxicity and its role in human nutrition and well-being have come under investigation. Reports have focused on the role of zinc toxicity in causes of copper deficiency, changes in the immune system and alterations in blood lipids. As the numerous challenges presented by the study of zinc in human nutrition are met, more appropriate recommendations for dietary and therapeutic zinc intake are being made.

    Nutrition is one of the foundations of cardiovascular guidelines for risk reduction and treatment. However, little is known about whether cardiologists, cardiology fellows-in-training, and cardiovascular team members have the nutrition education and knowledge necessary to implement these guidelines. The aim of this study was to describe the educational experiences, attitudes, and practices relating to nutrition among cardiovascular professionals. Surveys completed by cardiologists, fellows-in-training, and cardiovascular team members inquired about their personal dietary habits, history of nutrition education, and attitudes regarding nutrition interventions. A total of 930 surveys were completed. Among cardiologists, 90% reported receiving no or minimal nutrition education during fellowship training, 59% reported no nutrition education during internal medicine training, and 31% reported receiving no nutrition education in medical school. Among cardiologists, 8% described themselves as having "expert" nutrition knowledge. Nevertheless, fully 95% of cardiologists believe that their role includes personally providing patients with at least basic nutrition information. The percentage of respondents who ate ≥5 servings of vegetables and fruits per day was: 20% (cardiologists), 21% (fellows-in-training), and 26% (cardiovascular team members). A large proportion of cardiovascular specialists have received minimal medical education and training in nutrition, and current trainees continue to experience significant education and training gaps.

    This study was carried out to compare the effect between nutrition education intervention and non-nutrition education intervention on awareness regarding iron deficiency among schooling adolescents in Tanah Merah, one of rural district in Kelantan, Malaysia. This study which was started in year 2010 involved 280 respondents (223 girls, 57 boys, age: 16 yr) from schools in Tanah Merah. The selection criteria were based on hemoglobin level (Hb = 7 - 11.9 g/dL for girls; Hb = 7 - 12.9 g/dL for boys). They were divided into 2 groups. The first group received nutrition education package (Nutrition education, NE), whereas another group was entitled to receive non-nutrition education intervention (Non-Nutrition Education, NNE) (supplement only). Both interventions were implemented for 3 months. The changes in awareness among respondents of both groups were evaluated using multi-choices questionnaire. Nutrition education receiver group (NE) demonstrated improvement in awareness at post-intervention. No substantial improvement was demonstrated by the counterpart group (NNE). Multimedia nutrition education program conducted at school setting was in fact practical and effective in improving awareness on iron deficiency among anemic adolescents.

    Full Text Available The objective was to determine the prevalence of iron, folates and retinol deficiencies in school children and to evaluate the changes after an intervention of nutritional education. The project was developed in 17 schools. The sample included 1,301 children (678 males and 623 females. A subsample of 480 individuals, was randomly selected for drawing blood for biochemical determinations before and after the intervention of nutritional education, which included in each school: written pre and post-intervention tests, 6 workshops, 2 participative talks, 5 game activities, 1 cooking course and 1 recipe contest. Anthropometrical and biochemical determinations included weight, height, body-mass index, nutritional status, hematocrit, serum ferritin, retinol and folate concentrations. There was high prevalence of iron (25%, folates (75% and vitamin A (43% deficiencies in school children, with a low consumption of fruit and vegetables, high consumption of soft drinks and snacks and almost no physical activity. The nutritional education intervention produced a significant reduction in iron deficiency prevalence (25 to 14%, and showed no effect on vitamin A and folates deficiencies. There was a slight improvement in nutritional status. This study shows, through biochemical determinations, that nutritional education initiatives and programs have an impact improving nutritional health in school children.

    Nutritional diseases (mineral deficiencies) of farm animals are one of the limiting factors in animal production in Turkey. Present knowledge of mineral deficiencies of farm animals is derived from the study of severe deficiency conditions. Examples in sheep are deficiencies of copper in the central area of the Black Sea region and of selenium in the interior of Anatolia. Phosphorus deficiency is becoming the most serious problem in cattle. Outbreaks of wool shedding in sheep in central Anatolia are also becoming more severe. It is also likely that moderate (borderline) mineral deficiencies exist on a large scale. A general overview of trace mineral deficiencies and recent studies carried out to diagnose and correct them with the aid of biochemical and radioisotopic parameters is presented and discussed.

    Copper deficiency is a known cause of anemia and neutropenia that is easily remedied with copper supplementation. Copper is primarily absorbed in the stomach and proximal duodenum, so patients receiving enteral nutrition via methods that bypass this critical region may be at increased risk for copper deficiency. In pediatrics, postpyloric enteral feeding is increasingly utilized to overcome problems related to aspiration, severe reflux, poor gastric motility, and gastric outlet obstruction. However, little is known about the prevalence of copper deficiency in this population. We describe three pediatric patients receiving exclusive jejunal feeds who developed cytopenias secondary to copper deficiency. © 2017 Wiley Periodicals, Inc.

    Iodine deficiency is a risk factor for the growth and development of up to 800 million people living in iodine deficient environments throughout the world. The effects on growth and development, called the iodine deficiency disorders (IDD), comprise goiter, stillbirths and miscarriages, neonatal and juvenile thyroid deficiency, dwarfism, mental defects, deaf mutism, and spastic weakness and paralysis, as well as lesser degrees of loss of physical and mental function. All these effects are due to inadequate thyroid hormone production because iodine is an essential constituent of the thyroid hormone. In the West, IDD has been largely eliminated by the addition of iodine to the diet through iodized salt or through changes in food distribution and technology. IDD still persists in certain areas of Europe where these dietary changes have not occurred. In the Third World, IDD is a major problem in many countries with large populations, such as China, India, Indonesia, Nigeria, and Zaire. In these and other Third World countries, IDD is a significant barrier to social and economic progress which can be removed by correction of the deficiency. This book shows that elimination of iodine deficiency is feasible within the next decade, only requiring a modest financial and technical effort from the West. Part 1 reviews IDD in man and animals. Part 2 discusses the control of iodine deficiency disorders through iodine supplementation, and considers action at the national and international level. Part 3 presents a global review of the status of IDD control. There is a brief conclusion on the way forward to successful control programs.

    Full Text Available Breastfeeding is the best source of nutrition for every infant, and exclusive breastfeeding for 6 months is usually optimal in the common clinical situation. However, inappropriate complementary feeding could lead to a nutrient-deficient status, such as iron deficiency anemia, vitamin D deficiency, and growth faltering. The recent epidemic outbreak of obesity in Korean children emphasizes the need for us to control children’s daily sedentary life style and their intakes of high caloric foods in order to prevent obesity. Recent assessment of breastfeeding in Korea has shown that the rate is between 63% and 89%; thus, up-to-dated evidence-based nutritional management of breastfeeding infants to prevent common nutrient deficiencies or excesses should be taught to all clinicians and health care providers.

    Full Text Available Identification, propagation, and introduction of a nutritionally rich, indigenous plant species in the existing cropping system are presented in this paper as a method of rural nutrition intervention. A case study of Moringa (Moringa oleifera Lam., Moringaceae, which is a common tree in Malawi and one of the richest sources of vitamin A and vitamin C compared to the commonly consumed vegetables is presented to address the problem of vitamin A deficiency. After a brief review of the prevalence of vitamin A deficiency and the efforts to reduce its incidence in Malawi, Moringa is suggested as a potential solution to the problem. A framework for designing nutrition intervention with Moringa is described for actual implementation. It is argued that attempts to identify, document, and encourage the utilization of nutrient-rich indigenous plants could be cost-effective, and a sustainable method of improving the nutritional status of local populations.

    Nutritional rickets is usually attributed to vitamin D deficiency. Studies from some tropical countries have postulated low dietary intake of calcium as the cause of nutritional rickets. Both vitamin D and dietary calcium deficiency are highly prevalent in India. Information on their relative contribution in the development of rickets in Indian children is limited. The aim was to study the role of calcium and vitamin D deficiency in causation of nutritional rickets in young Indian children. In a case-control study, 67 children with nutritional rickets and 68 age- and sex-matched healthy controls were compared for demographic factors, nutritional status, sun exposure (UV score), dietary calcium and phytate intake (for subjects not breast-fed at presentation), and biochemical parameters [serum calcium, inorganic phosphate, alkaline phosphatase, 25-hydroxyvitamin D (25OHD), and PTH]. Mean intake of calcium (204±129 vs. 453±234 mg/d; Prickets, significant negative correlations were seen between dietary calcium intake and radiological score (r=-0.28; P=0.03) and PTH (r=-0.26; P=0.02). No correlation was found between serum 25OHD level and radiological score or biochemical parameters of rickets. Rickets develops when low dietary calcium intake coexists with a low or borderline vitamin D nutrition status.

    Children with autism spectrum disorder (ASD) are at risk of developing nutritional deviations. Three to six year old children with ASD were compared to their typically developing siblings and to a typically developing age and gender matched control group, in order to evaluate their intake and body mass index. Nutrient intake was compared to the Dietary Reference Intake using three-day diet diaries completed by the parents. The sum percentage of nutritional deficiencies in the ASD group compared to the typical development group was 342.5% (±122.9%) vs. 275.9% (±106.8%), respectively (P=0.026). A trend toward higher deficiency in the ASD group was observed as compared to the sibling group 363% (±122.9%) vs. 283.2% (±94.7%) (P=0.071). A higher body mass index was found in the ASD group compared to their counterparts, despite their nutritional deficiencies. In conclusion, children with ASD are more likely to suffer from nutritional deficiencies despite higher body mass index. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Background: Iron deficiency is the most common aetiology of anaemia worldwide and has several risk factors. Although iron deficiency anaemia (IDA) can occur at any age, women from reproductive age group are particularly vulnerable to develop IDA due to increased nutritional demand during pregnancy. Objective was to determine the frequency and nutritional risk factor of iron deficiency anaemia in women of child bearing age. This descriptive, cross sectional study was conducted from October 2005 to March 2006 at the Department of Medicine, Ward-5, and out-patients department of Jinnah Postgraduate Medical Centre, Karachi. Method: Two hundred non-pregnant females of child bearing age were included in the study; 100 with no previous pregnancy and remaining 100 with at least one prior history of pregnancy. All the relevant information, i.e., demographic and socioeconomic was collected through a questionnaire. Results: Two hundred patients with signs and symptoms of anaemia were recruited. Out of them 89 patients were found to be having iron deficiency anaemia in various age groups. Results also showed that dietary habit of patients was one of the causative factors leading to iron deficiency anaemia. Conclusion: To overcome iron deficiency anaemia a thorough and comprehensive strategy is required, i.e., educating the subjects to consume food rich in iron, community based program, monitoring severely anaemic cases and their treatment.

    This paper is an attempt to explore the relationship between protein consumption and BMI for the adult Santhals, a tribal community of West Bengal, India. For this purpose, a cross sectional sample of 1262 adult Santhals were mea- sured. A high incidence (46.9%) of chronic energy deficiency (CED) is observed. A low production of protein rich food items such as pulses, poultry and fishing within their own economy reveal that the barter system fails to provide enough protein rich food items for the community. Along with this, low income earning opportunities lead to a low consumption of protein rich food and hence a high incidence of undernutrition. The occupational pattern reveals that the Santhals who derive livelihood by the means of hard physical activities are more prone to develop CED. The study suggests that the overdependence on forests and their own economy for consumption needs may not be helping this community in attaining a better health status.

    Full Text Available Introduction: Cerebral palsy (CP refers to a spectrum of disorders causing physical and intellectual morbidity. Macro and micro nutrient deficiencies often contribute to the subnormal physical and mental capabilities of them. Objectives: To assess the growth, nutritional status, physical and functional ability and quality of life in cerebral palsy children and to determine any relation with their gross motor and functional capabilities. Method: The study was conducted at a Tertiary Care Centre, with the participants in the age group 1-16 years. A pretested evaluation tool was prepared which included Anthropometric measurements, tests for hemoglobin and Vitamin D estimation, evidence of micronutrient deficiencies, Dietary patterns, Epidemiological factors, Functional assessment using GMFM (Gross Motor Function Measure and FIM (Functional Independent Measurement scales and Quality of life (QOL assessment. The data was statistically analyzed. Results: Out of the 41 children, 30 had quadriplegia, 3 had hemiplegia and 8 had spastic diplegia. 34 (82.9% were severely underweight, 35 (85.4% had severe stunting and 38 (92.7% had severe wasting. Micronutrient deficiencies were noted like vitamin B complex deficiency in 37 (90.2%, vitamin A deficiency in 31 (75.6%, low vitamin D levels in 27 (65.9% and insufficient levels in 9 (22%, severe anemia in 5 (12.2% and moderate anemia in 26 (63.4%.The gross motor and functional scores were suboptimum in the majority of patients and the care givers had significant impairment in the quality of life. Conclusion: Majority of children with cerebral palsy had multiple nutritional deficiencies, gross motor and functional disabilities. QOL of the children and their care givers were suboptimum. A comprehensive package that address dietary intake, correction of micronutrient deficiencies especially anemia and vitamin D deficiency, physical and emotional support is recommended for the wellbeing of the affected children.

    Full Text Available Iron deficiency anemia in athletes is a very common condition that leads to reduced physical performance. Athletes are susceptible of falling iron deposits, mainly by an increase in its use, by its loss, or by insufficient intake. The present review aims to establish the basis of current knowledge environment: sports-athletes who have increased risk of anemia, etiology of iron deficiency anemia in the sporting group, providing dietary and nutritional guidelines for its prevention. The databases searched were Pubmed, Scirus and Scielo, as well as the official pages of prestigious organizations, recovering items by keywords: “iron-deficiency anemia”, “sports”, “athletic performance”, “iron intake “or Spanish counterparts. Iron deficiency anemia affects mainly endurance athletes (especially women and marathon and the members of team sports with high impact (volleyball and handball. Usually secondary anemias from hemolysis and oxidative stress resulting from the practice of sport, but it cases have also been documented by increased iron losses associated with exercise. Dietary and nutritional practices to prevent iron deficiency anemia in athletes should aim to ensure: carbohydrate intake between 60-65% of total energy daily minimum intake of 1.4 g of protein per day and a consumption of 20-40 mg iron daily, separating the intake of the main absorption inhibitors (phytate, tanetos and calcium. You need assessed by analytical iron status of the athlete every 2-3 months.

  17. Lessons to be learned: a case study approach. Vitamin B12 deficiency of nutritional origin.

    1997-10-01

    The case is presented of a 14 year old boy who developed severe anaemia at the onset of puberty caused by nutritional deficiency of vitamin B12 of about 10 years duration. The dietary intake comprised mainly chips, ice-cream, fruit and Coca-Cola--with small amounts of vitamin B12 from occasional slices of chicken meat. His denial of abnormal nutritional intake, supported by his mother, delayed confirmation of the correct diagnosis. However, the true situation was eventually confessed--and following implementation of a normal diet he rapidly improved clinically, the haemoglobin value rose to normal and he subsequently remained well.

    Nutritional deficiencies are known to be associated with hair loss; however, the exact prevalence is not known. The aim of this study is to evaluate the prevalence of nutritional deficiencies in participants with hair loss. In this cross-sectional study, 100 enrolled participants were divided into telogen effluvium (TE), male-pattern hair loss (MPHL), and female-pattern hair loss (FPHL) based on the type of hair loss. All participants underwent laboratory estimation for micronutrients and amino acid levels. Participants with hair loss showed varied amino acid and micronutrient deficiencies across all types of hair loss. Nutritional status did not vary much between the types of hair loss. Among the essential amino acids, histidine deficiency was seen in >90% of participants with androgenic alopecia and 77.78% of participants with TE while leucine deficiency was seen 98.15% of participants with TE and 100% with FPHL. Valine deficiency was also very common across alopecia subtypes. Among the nonessential amino acids, alanine deficiency was observed in 91.67% FPHL, 91.18% MPHL, and 90.74% TE. Cysteine deficiency was present in 55.58% and 50% of participants with MPHL and TE, respectively. A relatively higher proportion of participants with TE had iron deficiency compared to androgenic alopecia ( P = 0.069). Zinc deficiency was seen in 11.76% of participants with MPHL while copper deficiency was seen in 29.41% and 31.48% of participants with MPHL and TE, respectively. Nutritional deficiency is a common problem in participants with hair loss irrespective of the type of alopecia. The findings of our study suggest need for identification and correction of nutritional deficiencies in patients with hair loss.

    Full Text Available The effects of NO3- nutrition on iron deficiency responses were investigated in Arabidopsis thaliana. Plants were grown with or without 5 µM Fe, and with NO3- alone or a mixture of NO3- and NH4+. The results indicated that, NO3- nutrition induced higher dry matter production, regardless the Fe concentration. Fe deficiency reduced growth activity, photosynthetic pigment concentration and Fe content of plants, whatever the N forms. This decrease was more pronounced in plants grown with mixed N source; those plants presented the highest EL and MDA and anthocyanin contents compared to plants grown under Fe sufficient conditions. In iron free-solutions, with NO3- as the sole nitrogen source, enhanced FC-R activity in the roots was observed. However, in the presence of NH4+, plants displayed some decrease in in FC-R and PEPC activities. The presence of NH4+ modified typical Fe stress responses in Arabidopsis thaliana plants.

    In recent years, a role for epigenetic modifications in the pathophysiology of disease has received significant attention. Many studies are now beginning to explore the gene–environment interactions, which may mediate early-life exposure to risk factors, such as nutritional deficiencies and later development of behavioral problems in children and adults. In this paper, we review the current literature on the role of epigenetics in the development of psychopathology, with a specific focus on the potential for epigenetic modifications to link nutrition and brain development. We propose a conceptual framework whereby epigenetic modifications (e.g., DNA methylation) mediate the link between micro- and macro-nutrient deficiency early in life and brain dysfunction (e.g., structural aberration, neurotransmitter perturbation), which has been linked to development of behavior problems later on in life.

    Full Text Available Abstract Among dietary factors, learning and behavior are influenced not only by nutrients, but also by exposure to toxic food contaminants such as mercury that can disrupt metabolic processes and alter neuronal plasticity. Neurons lacking in plasticity are a factor in neurodevelopmental disorders such as autism and mental retardation. Essential nutrients help maintain normal neuronal plasticity. Nutritional deficiencies, including deficiencies in the long chain polyunsaturated fatty acids eicosapentaenoic acid and docosahexaenoic acid, the amino acid methionine, and the trace minerals zinc and selenium, have been shown to influence neuronal function and produce defects in neuronal plasticity, as well as impact behavior in children with attention deficit hyperactivity disorder. Nutritional deficiencies and mercury exposure have been shown to alter neuronal function and increase oxidative stress among children with autism. These dietary factors may be directly related to the development of behavior disorders and learning disabilities. Mercury, either individually or in concert with other factors, may be harmful if ingested in above average amounts or by sensitive individuals. High fructose corn syrup has been shown to contain trace amounts of mercury as a result of some manufacturing processes, and its consumption can also lead to zinc loss. Consumption of certain artificial food color additives has also been shown to lead to zinc deficiency. Dietary zinc is essential for maintaining the metabolic processes required for mercury elimination. Since high fructose corn syrup and artificial food color additives are common ingredients in many foodstuffs, their consumption should be considered in those individuals with nutritional deficits such as zinc deficiency or who are allergic or sensitive to the effects of mercury or unable to effectively metabolize and eliminate it from the body.

    Full Text Available Foram estudadas as alterações eletrencefalográficas em 20 crianças desnutridas. Foi assinalada diferença significativa entre o EEG dos pacientes com desnutrição global e daqueles com desnutrição protêica. Essas alterações foram caracterizadas pela presença de anormalidades encefálicas difusas e/ou descargas focais de tipo epiléptico. A incidência relativamente alta de descargas focais pode ser explicada pelo limiar convulsiógeno muito baixo do cérebro de crianças com desnutrição.The EEG changes in a group of 20 children with nutritional disorders are reported. The results suggest a significant difference in the EEG of patients with undernutrition and those with protein-caloric deficiency. These alterations correspond to the incidence of diffuse cerebral involvement and or discharges of an epileptic focal activity. The relatively high incidence of focal discharges may be explained on the basis of a very low epileptiform threshold of the cerebral cortex in children with nutritional disease.

    In the period between 1880 and 1930, the role of nutrition and nutritional deficiency as a cause of rickets was established based upon the results from 6 animal models of rickets. This greatly prevalent condition (60%-90% in some locales) in children of the industrialized world was an important clinical research topic. What had to be reconciled was that rickets was associated with infections, crowding, and living in northern latitudes, and cod liver oil was observed to prevent or cure the disease. Several brilliant insights opened up a new pathway to discovery using animal models of rickets. Studies in lion cubs, dogs, and rats showed the importance of cod liver oil and an antirachitic substance later termed vitamin D. They showed that fats in the diet were required, that vitamin D had a secosteroid structure and was different from vitamin A, and that ultraviolet irradiation could prevent or cure rickets. Several of these experiments had elements of serendipity in that certain dietary components and the presence or absence of sunshine or ultraviolet irradiation could critically change the course of rickets. Nonetheless, at the end of these studies, a nutritional deficiency of vitamin D resulting from a poor diet or lack of adequate sunshine was firmly established as a cause of rickets.

    Full Text Available The planting of forest species is an activity that, besides introducing new exotic types of plants, can lessen the environmental impacts resulting from extractivism. Nevertheless, such success depends, upon other factors, on the knowledge of the nutritional needs of the species to be used. This study intended to check the typical symptoms of nutritional deficiency of macronutrients in the culture of Neem, through the visual observation of the plants. The experiment was carried out in a greenhouse at the College of Agronomy and Veterinary Medicine (FAMEV of the Federal University of Mato Grosso (UFMT in Cuiabá/MT, and it was set up in randomized blocks, with seven treatments and three repetitions. Each experimental unit was represented by a plastic vase, two liters capacity. The treatments used were: complete nutritive solution and solution with the omission of the following nutrients: -N, -P, -K, -Ca, -Mg and -S. It was ascertained that the visual symptoms of nutrient deficiency were, as a general rule, of easy characterization except for the treatment with omission of sulphur. Therefore, the omission of macronutrients decreases the production of total dry matter of the Neem plants, except for the omission of the S nutrient.

    Full Text Available Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cell-mediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal non-zinc-deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n=31 and an experimental group (10 mg Zn/day, n=31 for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1 an increased body mass index for age and an increased phase angle in the experimental group; (2 a positive correlation between nutritional assessment parameters in both groups; (3 increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4 increased consumption of all nutrients, including zinc, in the experimental group; and (5 an increased serum zinc concentration in both groups (p<0.0001. Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.

    A 26-week nutrition intervention, including 4 weeks of nutrition education, combined with an increase in the content and bioavailability of dietary iron for 22 weeks was carried out in 34 intervention and 34 control adolescent girls suffering from mild iron deficiency anemia (IDA). In post-intervention, hemoglobin and serum ferritin were significantly higher in the intervention group, whereas the incidence of IDA was significantly lower in the intervention group compared to the control group. Nutrition knowledge scores were significantly higher in intervention girls compared to control girls. Dietary changes to improve available dietary iron can reduce iron deficiency anemia.

  8. Processes underlying the nutritional programming of embryonic development by iron deficiency in the rat.

    Angelina Swali

    Full Text Available Poor iron status is a global health issue, affecting two thirds of the world population to some degree. It is a particular problem among pregnant women, in both developed and developing countries. Feeding pregnant rats a diet deficient in iron is associated with both hypertension and reduced nephron endowment in adult male offspring. However, the mechanistic pathway leading from iron deficiency to fetal kidney development remains elusive. This study aimed to establish the underlying processes associated with iron deficiency by assessing gene and protein expression changes in the rat embryo, focussing on the responses occurring at the time of the nutritional insult. Analysis of microarray data showed that iron deficiency in utero resulted in the significant up-regulation of 979 genes and down-regulation of 1545 genes in male rat embryos (d13. Affected processes associated with these genes included the initiation of mitosis, BAD-mediated apoptosis, the assembly of RNA polymerase II preinitiation complexes and WNT signalling. Proteomic analyses highlighted 7 proteins demonstrating significant up-regulation with iron deficiency and the down-regulation of 11 proteins. The main functions of these key proteins included cell proliferation, protein transport and folding, cytoskeletal remodelling and the proteasome complex. In line with our recent work, which identified the perturbation of the proteasome complex as a generalised response to in utero malnutrition, we propose that iron deficiency alone leads to a more specific failure in correct protein folding and transport. Such an imbalance in this delicate quality-control system can lead to cellular dysfunction and apoptosis. Therefore these findings offer an insight into the underlying mechanisms associated with the development of the embryo during conditions of poor iron status, and its health in adult life.

    Full Text Available Background: Poor nutrition has been associated with impaired immunity and accelerated disease progression in HIV- infected children. The aim of this study was to quantify the levels of nutrient intake in HIV-infected children and compare these to standard recommendations. Methods: We surveyed HIV-infected Tanzanian children enrolled in a pediatric care program that provided routine nutritional counseling and vitamin supplementation. We obtained anthropometric measurements and determined 24-hour macronutrient and micronutrient intakes and food insecurity. Values were compared to recommended nutrient intakes based on age and gender. Results: We interviewed 48 pairs of children and their caregiver(s. The age of the child ranged from 2-14 years; median age 6 and 60% female. The median weight-for-height z-score for children ≤ 5 years was 0.69 and BMI-for-age z-scores for children >5 was -0.84. Macronutrient evaluation showed that 29 (60% children were deficient in dietary intake of energy; deficiency was more common in older children (p=0.004. Micronutrient evaluation shows that over half of study subjects were deficient in dietary intake of vitamin A, vitamin D, vitamin E, thiamine, riboflavin, niacin, folate, vitamin B12, and calcium. Food insecurity was reported by 20 (58% caregivers. Conclusions and Public Health Implications: The diets of many HIV-infected children at a specialized treatment center in Tanzania do not meet recommended levels of macro- and micro-nutrients. Food insecurity was a contributory factor. Enhanced dietary counseling and provision of macro- and micro-nutrient supplements will be necessary to achieve optimal nutrition for most HIV-infected children in resource-poor regions.

    There is an expanding prevalence pool of heart failure (HF) due to the increasing prevalence of survivors of myocardial infarction, diabetes, hypertension, chronic kidney disease, and obesity. There is increasing interest in the role of nutrition in all forms of HF, given observations concerning micro- and macronutrient deficiencies, loss of lean body mass or sarcopenia, and their relationships with hospitalization and death. This review examines the relationships among loss of lean body mass, macro- and micronutrient intake, and the natural history of HF, particularly in the elderly, in whom the risks for all-cause rehospitalization, infection, falls, and mortality are increased. These risks are potentially modifiable through strategies that improve nutrition in this vulnerable population.

    2016-09-01

    Full Text Available Over two billion people suffer from micronutrient deficiencies. Food fortification is a prominent nutrition intervention to combat such deficiencies; however, its effectiveness, risks, and ethical implications vary depending on the contexts associated with the deficiency it is addressing and the circumstances with its implementation. The aim of this research was to analyse the profile of nutrition interventions for combating micronutrient deficiency with particular focus on food fortification reported in existing systematic reviews (SRs, guidelines and policy statements, and implementation actions for nutrition. A review of secondary data available from online databases of SRs, guidelines and policy statements, and implementation actions, categorised as either “nutrition-specific interventions” (NSpI or “nutrition-sensitive interventions” (NSeI, was conducted. Currently, there is evidence available for a diversity of food fortification topics, and there has been much translation into action. Indeed, food fortification and micronutrient supplementation interventions and NSpI more broadly dominate the profile of interventions for which there were SRs, guidelines, and policy statements available. The findings demonstrate that, although there is a rational linear relationship between evidence synthesis and translation in formulating policy and actions to combat micronutrient deficiencies, the various nutrition interventions available to help combat micronutrient deficiencies are not equally represented in the evidence synthesis and translation processes. Effective and safe policies and actions to combat micronutrient deficiencies require decisions to be informed from a body of evidence that consists of evidence from a variety of interventions. Into the future, investment in making available a higher number of SRs, guidelines and policy statements, and actions of NSeI is indicated.

    The gluten-free diet has traditionally been accepted as a healthy diet, but there are articles advocating that it may have some nutritional deficiencies. The current study assesses whether there was any change in the contributions of calories, essential elements, proportion of fatty acids, vitamins, minerals and fiber in children who were diagnosed with celiac diseases, comparing the diet with gluten prior one year after diagnosis with the diet without gluten to the year of diagnosis. The level of clinical or analytical impact that nutritional deficits could have was also assessed. A prospective,descriptive, observational study in which information was collected from a dietary survey, anthropometric and analytical data at pre-diagnosis of celiac disease and following a gluten diet and one year after celiac disease diagnosis, under gluten-free diet. A total of 37 patients meet the study criteria. A decrease in the intake of saturated fatty acids was found, with an increase of monounsaturated fatty acids and an increase in the intake of phosphorus in the diet without gluten. A deficient intake of vitamin D was found in both diets. Clinically, at year of gluten-free diet there was an improvement in weight and size. Analytically, there was an improvement in hemoglobin, ferritin, vitamin D, and parathyroid hormone in plasma. The gluten-free diet has minimal deficiencies, similar to those present in the diet with gluten, with an improvement in the lipid profile by increasing the proportion of monounsaturated fatty acids to the detriment of saturated fatty acids.

    ME. Silva-Stenico

    Full Text Available It is well known that citrus plants that have been infected by Xylella fastidiosa display nutritional deficiencies, probably caused by production of extracellular polymers by the bacteria that block normal nutrient flow through the xylem. The aim of this work was to study the mineral composition of specific foliar areas in different stages of infection in citrus. Thus, the concentrations of macro and micronutrients in leaves of citrus infected by X. fastidiosa were measured. Samples from four infected citrus orchards in the State of São Paulo, Brazil, were respectively collected from Santa Rita do Passa Quatro, Neves Paulista, Gavião Peixoto and Paraíso counties. The presence of X. fastidiosa in leaves was confirmed by polymerase chain reaction (PCR using specific PCR primers. To understand the variation in leaf-nutrient content in citrus plants, we used foliar nutrient values from control (non-symptomatic plants as a reference. Chemometric analysis showed that the deficiency of P and K in symptomatic trees for all orchards and high concentrations of Fe, Mn and Zn were observed in chlorotic areas, although other studies revealed deficiency of zinc in leaves. This is the first report showing that a correlation between chlorotic citrus leaf and higher concentrations of Fe, Mn and Zn are observed when infected and healthy plants were compared.

    Over the past few years, we have observed increasing consumption of inappropriate plant milks as an alternative to infant milk formula. Some families believe that foods labeled as natural are the most healthy and an appropriate nutritional choice. However, their composition does not respect European recommendations. They are always hypocaloric and protein, vitamin, and mineral concentrations are inadequate. The aim of this study was to report severe nutritional complications after inappropriate plant milk consumption. Between 2008 and 2011, we studied severe nutritional deficiencies caused by consumption of plant milks bought in health food stores or online shops. Infants were identified in our centers and examined through medical history, physical examination, and laboratory testing. Nine cases of infants aged from 4 to 14 months were observed. In all cases, these milks were used as an alternative to milk formulas for supposed cow's milk allergy. At diagnosis, four patients were aged 6 months or less. They had received plant milk exclusively for 1-3 months. The beverages consumed were rice, soya, almond and sweet chestnut milks. In three cases, infants presented severe protein-calorie malnutrition with substantial hypoalbuminemia (slow down the progress of this social trend. Copyright © 2014 Elsevier Masson SAS.

    A 6-month-old intact female giant schnauzer dog fed a nutritionally unbalanced homemade diet was evaluated because of a 1-month history of lameness and difficulty walking. Abnormalities identified on ancillary tests, in conjunction with the dog's clinical improvement following diet change, suggested a diagnosis of vitamin D deficiency and nutritional secondary hyperparathyroidism. This report underlines the importance of appropriate feeding management, especially during the vulnerable growth phase.

    Full Text Available Background: The incidence of riboflavin deficiency is high in women and children in developing countries and the deficiency almost invariably occurs in combination with deficiencies of other water soluble vitamins. The objective of this study was the assessment of riboflavin status of rural school children in Kerman province and its relationship with riboflavin, protein and energy intake. Methods: In this cross-sectional study, 327 primary school children were randomly selected by the stratified multistage cluster sampling method. Variables for classifications were sex and socio-economic status (according to the educational level. This study was conducted by the Department of Nutrition and Biochemistry of School of Public Health in Tehran University in the winter of 2001. A twenty-four hour recall questionnaire was completed by and 5 cc of venous blood was taken from each student. Riboflavin status was assessed by measuring the glutathione reductase activity coefficient (EGR – AC of the red blood cells. Chi-Square and Pearson’s correlation coefficient tests were used to determine correlations. Student’s t–test was used to show the differences in the mean of EGR – AC between the classifications of independent factors. Results: The relationship between riboflavin status and its independent variables including the status of riboflavin, protein and calorie intake were assessed. Outputs of the study indicated that 39.7% of the boys and 43.6% of the girls (41.8% together were marginally riboflavin deficient. Furthermore, 37.7% of the boys, 33.4% of the girls (35.4% together were frankly riboflavin deficient. An average of 67.2% of the children (70.1% boys, 63.7% girls had enough intake of riboflavin, and 76.2% of the children (79.9%, boys, 72.5% girls had adequate intake of protein. However, only 22% of the children (24.5% boys, 19.3% girls had sufficient caloric intake. Outputs of this dietary evaluation reveal that there is a relationship

    Full Text Available Abstract Background The term iodine deficiency disorders (IDD refers to all the effects of iodine deficiency on growth and development in human and animal populations that can be prevented by correction of the iodine deficiency. The objective of this paper was to determine the iodine nutrition status among schoolchildren in the Jazan Region of the Kingdom of Saudi Arabia (KSA, by measuring urinary iodine concentrations and by clinical assessments of goiter rate. Methods A school-based cross-sectional survey was conducted in the Jazan region of southwestern KSA from May to November 2010. A total of 311 children, aged 6–13 years, drawn from 12 schools, were selected by a three-stage cluster random sampling method. Data on sociodemographic characteristics were collected using a structured questionnaire. Urine samples were collected and physical examinations were conducted to determine the presence or absence of goiter. Data were analyzed using SPSS version 17.0. Chi square and independent t-tests were used for proportions and mean comparisons between groups. Results Out of 360 selected children, 311 were examined. There were 131 males (42% and 180 females (58%. The median urinary iodine concentration (UIC of the study group was 421 μg/L. The study population proportion with UIC > 300 μg/L was 74% with a higher proportion among males and urban populations. The proportion of children with UIC of 100–300 μg/L was only 21% and was significantly higher among females compared with males (p Conclusions The present study demonstrates a remarkable achievement in Universal Salt Iodization (USI and IDD elimination goals in the Jazan area. However, UIC levels reflect excessive iodine intake and may put the population at risk of adverse health consequences like iodine-induced hyperthyroidism and autoimmune thyroid diseases.

    Full Text Available Introduction. Cystic fibrosis (CF is a multisystemic autosomal recessive disease most frequently recognized by characteristic respiratory and/or digestive manifestations. Exceptionally rare, as is the case with the infant we are presenting, the initial sign of the disease can be nutritional deficiency dermatitis (NDD. Case Outline. A three-month-old male infant of young and healthy non-consanguineous parents, born at term after the first uneventful pregnancy, was hospitalized due to atopic dermatitis (AD-like skin changes, failure to thrive and normochromic anemia (Hb 60 g/L. As exclusively breast-fed, failure to thrive was attributed to hypogalactia and skin changes to nutritional allergy, so that, besides exclusion of cow’s milk protein and other highly allergenic foods in mother’s diet, hypoallergenic milk formula was added to the child’s diet. However, dietetic measures were without effect, and the child was re-hospitalized at age 4.5 months, this time in the condition of severe malnutrition with hypoproteinemic edemas, extensive dermatitis, moderate hepatosplenomegaly and recurrent normochromic anemia (Hb 57 g/L. After plasma-free erythrocyte transfusion, correction of hypoalbuminemia and two-week parenteral and semi-elementary nutrition resulted in gradual recovery of the child, also including the resolution of skin changes. Having in mind the clinical course of the disease, as well as the response to applied therapeutic measures, CF was suspected as the cause of the child’s problems, which was also confirmed by a high level of sweat chlorine (92 mmol/L and DNA analysis (∆F508/∆F508. Conclusion. Our experience indicates that NDD, as the initial manifestation of CF, should be also kept in mind in differential diagnosis of the infant’s AD-like changes.

    To describe the frequency of anemia and iron, zinc, copper and magnesium deficiencies among Mexican adolescents in the probabilistic survey ENSANUT 2006. The sample included 2447 adolescents aged 12 to 19 y. Capillary hemoglobin and venous blood samples were collected to measure the concentrations of ferritin, sTFR, CRP, zinc, iron, copper and magnesium. Logistic regression models were constructed to assess the risk for mineral deficiencies. The overall prevalence of anemia was 11.8 and 4.6%, body iron deficiency 18.2 and 7.9% for females and males, respectively. Overall prevalence of tissue iron deficiency was 6.9%, low serum copper were 14.4 and 12.25%; zinc 28.4 and 24.5%, magnesium 40 and 35.3%; for females and males, respectively. There is a high prevalence of mineral deficiency in Mexican adolescents; females were more prone to have more mineral deficiencies. Nutritional interventions are necessaries in order to reduce and control them.

  20. Nutritional Deficiencies, the Absence of Information and Caregiver Shortcomings: A Qualitative Analysis of Infant Feeding Practices in Rural China.

    Full Text Available Development during the first two years of life is critical and has a lasting impact on a child's health. Poor infant and child nutrition can lead to deficiencies in essential micronutrients, which may cause a weakened immune system and lasting effects on children's growth and development. Recent studies in rural Shaanxi Province found an anemia prevalence of 54.3% among rural children aged six to twelve months. While new large-scale, quantitative research has begun to catalogue the extent of child malnutrition and anemia, no effort has yet been made to look more closely at the potential reasons for rural children's nutritional deficiencies through qualitative analysis. This study aims to elucidate some of the fundamental causes of poor complementary feeding practices that may lead to anemia among children in rural Shaanxi Province, China.We interviewed sixty caregivers participating in a large survey on child health and nutrition. We conducted three waves of interviews with children's primary caregivers in seventeen rural villages within four nationally-designated poverty counties in the southern part of Shaanxi Province.The qualitative analysis reveals that poor complementary feeding practices are common across our sample. Information gathered from our interviews suggests that complementary feeding practices are impeded by two constraints: absence of understanding topics related to infant health and nutrition under caregivers, as well as inadequate sources of information on these topics. Poverty does not appear to constrain child feeding practices.Our results uncover lack of proper knowledge on infant and child nutrition among rural caregivers in China. This situation causes them to fail incorporating micronutrient rich foods in their children's diet. Age-appropriate complementary feeding can stimulate children's physical and cognitive development, but in its absence it leads to iron-deficiency anemia. We suggest that steps be taken to educate

    Full Text Available Abstract Background Protein and mRNA levels for several selenoproteins, such as glutathione peroxidase-1 (Gpx1, are down-regulated dramatically by selenium (Se deficiency. These levels in rats increase sigmoidally with increasing dietary Se and reach defined plateaus at the Se requirement, making them sensitive biomarkers for Se deficiency. These levels, however, do not further increase with super-nutritional or toxic Se status, making them ineffective for detection of high Se status. Biomarkers for high Se status are needed as super-nutritional Se intakes are associated with beneficial as well as adverse health outcomes. To characterize Se regulation of the transcriptome, we conducted 3 microarray experiments in weanling mice and rats fed Se-deficient diets supplemented with up to 5 μg Se/g diet. Results There was no effect of Se status on growth of mice fed 0 to 0.2 μg Se/g diet or rats fed 0 to 2 μg Se/g diet, but rats fed 5 μg Se/g diet showed a 23% decrease in growth and elevated plasma alanine aminotransferase activity, indicating Se toxicity. Rats fed 5 μg Se/g diet had significantly altered expression of 1193 liver transcripts, whereas mice or rats fed ≤ 2 μg Se/g diet had Conclusion This study shows that Se toxicity (5 μg Se/g diet in rats vastly alters the liver transcriptome whereas Se-deficiency or high but non-toxic Se intake elicits relatively few changes. This is the first evidence that a vastly expanded number of transcriptional changes itself can be a biomarker of Se toxicity, and that identified transcripts can be used to develop molecular biomarker panels that accurately predict super-nutritional and toxic Se status.

    There is a high risk of vitamin D (VD) deficiency in the population of southern Chile that can be treated with VD supplements. Weight excess (WE) can influence the response to supplements. To study the prevalence of VD deficiency and the effect of cholecalciferol (VD3) supplements in healthy children from Punta Arenas, Chile, and evaluate a possible association with nutritional status. Demographic and anthropometric data, as well as laboratory assessment of serum 25-hidroxyvitamin D (25OHD) and other bone metabolism parameters were evaluated. After baseline evaluation, children were supplemented with VD3 1600 IU/day for one month, after which 25OHD was retested. Of the 108 children studied, 50% were boys, and had a mean age of 9.6±0.5 years. Nutritional assessment showed that 39% had normal weight, 46% were overweight, and 15% were obese. Median 25OHD was 10.9ng/ml: 96.3% had deficiency (30ng/ml). Children with WE had a significantly lower increase in 25OHD than children with normal weight (5±5.5 vs. 7.7±4.9, p=03). Children with WE may require 32% higher VD dose than normal weight children to attain the same 25OHD concentration. Chilean schoolchildren from Punta Arenas have high prevalence of WE and VD deficiency, with a majority in the range of severe VD deficiency. WE interferes in the response to VD supplementation, leading to a lower increase in 25OHD. Copyright © 2015 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

    Background: Anemia is highly prevalent in Cambodian women and children, but data on causes of anemia are scarce. We performed a national micronutrient survey in children and women that was linked to the Cambodian Demographic Health Survey 2014 (CDHS-2014) to assess the prevalence of micronutrient deficiency, hemoglobin disorders and intestinal parasite infection. Methods: One-sixth of households from the CDHS-2014 were selected for a follow-up visit for the micronutrient survey. Households were visited from two weeks to two months after the CDHS-2014 visit. Data on micronutrient status were available for 1512 subjects (792 children and 720 women). Results: Anemia was found in 43% of the women and 53% of the children. Hemoglobin disorders affected >50% of the population, with Hemoglobin-E the most prevalent disorder. Deficiencies of iron (ferritin children, the prevalence of iron, vitamin A, vitamin B12 or folic acid deficiency was anemia in children, whereas in the women none of the factors was significantly associated with anemia. Iron deficiency anemia (IDA) was more prevalent in children children and women, the prevalence of IDA was anemia were hookworm infection and zinc and folic acid deficiency. Over 40% of the anemia was not caused by nutritional factors. Conclusion: The very high prevalence of anemia in Cambodian women and children cannot be explained solely by micronutrient deficiencies and hemoglobin disorders. Micronutrient interventions to improve anemia prevalence are likely to have limited impact in the Cambodian setting. The focus of current interventions to reduce the high prevalence of anemia in children and women should be broadened to include zinc and folic acid as well as effective anti-hookworm measures.

    This study was carried out in aerated nutritive solution to evaluate the effect of macronutrients, boron, and zinc omission on plant growth, dry matter production, visual symptoms and nutritional status of sunflower. The experiment was arranged in a completely randomized design with two replications and nine treatments corresponding to the complete solution (macro and micronutrients and individual omission of N, P, K, Ca, S, Mg, B and Zn. We measured plant height, number of leaves, stem diameter, leaf area and dry matter, and leaf content of macro and micronutrients. The individual omissions of N, P, K, and Ca were the most limiting to plant dry matter production, and resulted in morphological alterations represented by characteristical visual symptoms of the nutritional deficiency of each element.

    The review aims to summarize our current knowledge surrounding treatment strategies aimed at recovery of bone mass in energy-deficient women suffering from the Female Athlete Triad. The independent and interactive contributions of energy status versus estrogen status on bone density, geometry, and strength have recently been reported, highlighting the importance of addressing both energy and estrogen in treatment strategies for bone health. This is supported by reports that have identified energy-related features (low body weight and BMI) and estrogen-related features (late age of menarche, oligo/amenorrhea) to be significant risk factors for low bone mineral density and bone stress injury in female athletes and exercising women. Nutritional therapy is the recommended first line of treatment to recover bone mass in energy-deficient female athletes and exercising women. If nutritional therapy fails after 12 months or if fractures or significant worsening in BMD occurs, pharmacological therapy may be considered in the form of transdermal estradiol with cyclic oral progestin (not COC).

    Full Text Available Features of the development of cognitive functions in children 5-6 years of age with iron deficiency (ID were studied and the relationship of the revealed features of iron deficiency degree was established. After clinical and laboratory examination 205 children aged 5-6 years, pupils of pre-school institutions were included in the study. The core group consisted of 155 children, including 105 children with latent iron deficiency (LID and 50 children with iron deficiency anemia (IDA I degree. The control group consisted of 50 healthy children. To study cognitive function, "Approximate comprehensive program of study of children's readiness for school" was used. A significant decrease of average data of all mental functions (perception, memory, language, thinking, ima¬gination in children 5-6 years old with ID, most pronounced in children with IDA was revealed. Indicators of cognitive functions correspond predominantly to a mild and moderate level of development in children with IDA, the average - in children with LID, good and high - in healthy children. There was a significant direct correlation between the level of cognitive functioning and the level of hemoglobin, serum iron and ferritin. The effect of iron deficiency on the development of indicators of cognitive function toward their reduce in preschool children was established. The level of cognitive functioning depends on the degree of iron deficiency.

    Several potential proximate causes may be implicated in a recent (post-1984) decline in moose (Alces alces andersoni) numbers at their southern range periphery in northwest Minnesota, USA. These causes include deleterious effects of infectious pathogens, some of which are associated with white-tailed deer (Odocoileus virginianus), negative effects of climate change, increased food competition with deer or moose, legal or illegal hunting, and increased predation by gray wolves (Canis lupus) and black bears (Ursus americanus). Long-standing factors that may have contributed to the moose decline include those typically associated with marginal habitat such as nutritional deficiencies. We examined survival and productivity among radiocollared (n = 152) adult female and juvenile moose in northwest Minnesota during 1995–2000, and assessed cause of death and pathology through carcass necropsy of radiocollared and non-radiocollared animals.Aerial moose surveys suggested that hunting was an unlikely source of the numerical decline because the level of harvest was relatively low (i.e., approx. 15% / 2 yr) and the population usually grew in years following a hunt. The majority of moose mortalities (up to 87% of radiocollared moose [n = 76] and up to 65% of non-radiocollared moose [n = 84]) were proximally related to pathology associated with parasites and infectious disease. Liver fluke (Fascioloides magna) infections apparently constituted the greatest single source of mortality and caused significant pathology in the liver, thoracic and peritoneal cavities, pericardial sac, and lungs. Mortality due to meningeal worm (Parelaphostrongylus tenuis) was less prevalent and was manifested through characteristic neurological disease. Several mortalities apparently were associated with unidentified infectious disease, probably acting in close association with malnutrition. Bone-marrow fat was lower for moose dying of natural causes than those dying of anthropogenic factors or

    To explore the status of iodine nutrition and iodine deficiency disorders in the pasturing areas and agricultural regions in Tibet. 30 families were selected respectively in pastoral Dangxiong county and agricultural Qushui county of Lasa. Drinking water and edible salt were collected for testing the iodine contents. In each type of the following populations including children aged 8 - 10, women of child-bearing age and male adults, 50 subjects were randomly sampled to examine their urinary iodine contents. Among them, 50 children and 50 women were randomly selected for goiter examination by palpation. Water iodine content was less than 2 µg/L, both in pasturing area and in agricultural areas. There was no iodized salt used in the families of pasturing areas, while 90% people consumed iodized salt in agricultural areas. The median of urinary iodine in pasturing area was 50.2 µg/L, significantly lower than that of agricultural area (193.2 µg/L). However, the goiter rate of children and women in pasturing area was significantly lower than that in agricultural area. Although iodine intake of populations in pasturing area of Tibet was severely deficient, there was no epidemic of Iodine Deficiency Disorders. This phenomenon noticed by the researchers deserved further investigation.

The experiments were conducted with 1 day-old Cobb 500 broiler chickens. By the 3rd day of life, they were divided into 60 experimental and 20 control birds; the latter were fed a standard compound feed whereas the former group received a diet deficient in sulfur-containing amino acids methionine and cysteine (reduced up to 50%, vitamin E, and Se (from 0.2 mg/kg in standard feed to 0.01 mg/kg, further supplemented with 4% oxidized fat containing peroxides and aldehydes with peroxide number of the food 8.0 meq O2/kg. Peroxide number (meq O2/kg was determined in pork lard oxidised through UV irradiation as per BSS 11374:1986. The clinical signs of experimental muscle dystrophy in broiler chickens appeared first by the 19th day of feeding, when the severe clinical form was established and by the 21st and 25th day in the severe and the mild clinical form. The proportion of diseased chickens during the clinical period was the highest (93.3% mild and 46.6% severe clinical form, and gradually decreased after the treatment with Seled®. The 7-day treatment with Seled® at a dose of 0.06 mg/kg per os for compensation of Se deficiency and replacement of the deficient compound feed with a regular one contributed to recovery of birds by the 31st day after the therapy of mild experimental muscular dystrophy while birds affected by the severe clinical form could not recovery.

    Full Text Available Obesity and the associated metabolic syndrome are among the most common and detrimental metabolic diseases of the modern era, affecting over 50% of the adult population in the United States. Surgeries designed to promote weight loss, known as bariatric surgery, typically involve a gastric bypass procedure and have shown high success rates for treating morbid obesity. However, following gastric bypass surgery, many patients develop chronic anemia, most commonly due to iron deficiency. Deficiencies of vitamins B1, B12, folate, A, K, D, and E and copper have also been reported after surgery. Copper deficiency can cause hematological abnormalities with or without neurological complications. Despite oral supplementation and normal serum concentrations of iron, copper, folate, and vitamin B12, some patients present with persistent anemia after surgery. The evaluation of hematologic disorders after gastric bypass surgery must take into account issues unique to the postsurgery setting that influence the development of anemia and other cytopenias. In this paper, the clinical characteristics and differential diagnosis of the hematological disorders associated with gastric bypass surgery are reviewed, and the underlying molecular mechanisms are discussed.

    Female adolescents in reproductive age are a susceptible group to anemia and micronutrient deficiencies. The objective of this study was to know the nutritional, anthropometric and dietetic status, the prevalence of anemia, depletion of iron deposits (FeD) and Vitamin A deficiency (VAD) in female adolescents. Seventy-eight not pregnant female adolescents (15.9 +/- 1.1 years old), from an urban and a periurban zone of Maracaibo, and a rural zone near this city, without infectious and inflammatory processes, were analyzed. Anemia in adolescents was considered when Hb zone showed significant lower values of weight (p = 0.0024), height (p = 0.0027), body mass index BMI (p = 0.0487), fatty area (p = 0.0183), MCV (p = 0.0241), MCH (p = 0.0488), MHCC (p = 0.0228), and the highest prevalence of anemia (66.67%), anemia+FeD (33.33%), and anemia+FeD+RVAD (5.56%), with respect to adolescents from the urban zone. Although, anemic adolescents from the rural zone showed a non significant decrease of the iron percentage adjustment. Iron requirements are increased during adolescence, reaching a maximum at the peak of growth and remaining almost as high in girls after menarche, to replace menstrual losses. The low iron status among adolescents from the rural zone determine that this is a high risk group to anemia and FeD and they require prevention, control and suplementation strategies.

    Several contributory factors such as poverty, lack of purchasing power, household food insecurity, and limited general knowledge about appropriate nutritional practices increase the risk of undernutrition in developing countries. The synergistic interaction between inadequate dietary intake and disease burden leads to a vicious cycle that accounts for much of the high morbidity and mortality in these countries. Three groups of underlying factors contribute to inadequate dietary intake and infectious disease: inadequate maternal and child care, household food insecurity, and poor health services in an unhealthy environment.

  2. Nutritional and Acquired Deficiencies in Inositol Bioavailability. Correlations with Metabolic Disorders

    Full Text Available Communities eating a western-like diet, rich in fat, sugar and significantly deprived of fibers, share a relevant increased risk of both metabolic and cancerous diseases. Even more remarkable is that a low-fiber diet lacks some key components—as phytates and inositols—for which a mechanistic link has been clearly established in the pathogenesis of both cancer and metabolic illness. Reduced bioavailability of inositol in living organisms could arise from reduced food supply or from metabolism deregulation. Inositol deregulation has been found in a number of conditions mechanistically and epidemiologically associated to high-glucose diets or altered glucose metabolism. Indeed, high glucose levels hinder inositol availability by increasing its degradation and by inhibiting both myo-Ins biosynthesis and absorption. These underappreciated mechanisms may likely account for acquired, metabolic deficiency in inositol bioavailability.

    The gastric bypass has nutritional and electrolyte disturbances rate of approximately 17%. The most common deficits are protein malnutrition, ferric and zinc, in addition to the vitamin. Although rare, some malnutrition stages reach such severity that ends up being necessary hospitalization and sometimes revisional or reversal surgical procedures. To present a proposal of surgical revision for treatment of severe malnutrition after bariatric surgery. The procedure is to reconstitute the food transit through the duodenum and proximal jejunum, keeping the gastric bypass restrictive component. As an additional strategy, the gastric fundus resection is performed, aiming to intensify the suppression of the greline and avoiding excessive weight regain. After initial stabilization, nutritional and electrolytic support, the procedure was performed in two patients as definitive treatment of malnutrition status. Good results were observed at one year follow up. As improvement option and/or resolution of the nutritional alterations, surgical therapy is one of the alternatives. There is still no consensus on the surgical technique to be performed. This procedure is based on pathophysiological factors for the treatment of this condition, with good initial results, without significant clinical alterations. Longer follow-up will determine its effectiveness. O bypass gástrico consta com taxa de distúrbios nutricionais e eletrolíticos de aproximadamente 17%. Os déficits mais frequentes são a desnutrição proteica, férrica e de zinco, além das vitamínicas.

    Data on the vitamin D status of the population of Wallonia (Belgium, 51°30' North) are scarce. This study was carried out to estimate vitamin D deficiency, identify potential determinants, and analyze their relationship with vitamin D supplementation. We tested the hypothesis that vitamin D deficiency is common in the general population, particularly among subjects without supplementation. Vitamin D deficiency was defined as a serum level of 25-hydroxyvitamin D (25(OH)D) concentration less than 50nmol/L. Data were analyzed from 915 participants of the Nutrition, Environment and Cardio-Vascular Health cross-sectional survey. The median (interquartile range) 25(OH)D level was 53.1 (37.8-69.9) nmol/L, and 44.7% of the subjects were vitamin D deficient. Subjects without vitamin D supplementation were more concerned by vitamin D deficiency than those with supplementation (odds ratio [OR], 3.35; P work evidenced the high prevalence of 25(OH)D deficiency in the general population, especially among nonsupplemented subjects with obesity, low household income, and/or lack of light. Vitamin D supplementation looks effective in our population, especially via a stabilization of vitamin D coverage throughout the seasons. The best dietary strategy to achieve optimal 25(OH)D concentrations all year round in the general population requires more research. Copyright © 2015 Elsevier Inc. All rights reserved.

    The prevalence of obesity in Chilean children has been increasing steadily for the last two decades. The first study to determine nutritional status and food intake in a representative sample of this population was carried out in 1960. Recently the National Food Consumption Survey (ENCA) carried out in 2012 was released by the Ministry of Health. However, this study did not include biochemical determinations of micronutrients which would allow a better diagnosis of nutritional status in children. to review the literature available from 2004 to 2014 in food intake and nutritional status in Chilean children aged 4 to 14 years. a total of 362 references published between 2004 and 2014 were obtained through searches in the databases PubMed, Lilacs, Embase and Scielo. From these, 40 articles were selected for a thorough review. food intake by children is characterized by a high-energy intake, a low consumption of fruits and vegetables and a high consumption of bread. The ENCA showed that 95% of the Chilean population has a deficient diet. A high prevalence of obesity is observed from very early in life. There is a dearth of data available on plasma indicators of vitamin and mineral status since 1960, which would provide more reliable information on nutritional assessment. It is imperative to implement a representative nutrition survey of children in Chile that includes biochemical indicators to get reliable information in order to develop strategies aimed to correct micronutrient malnutrition from excess or deficiency.

    2018-03-01

    Full Text Available With the global population predicted to grow by at least 25% by the year 2050, the sustainable production of nutritious foods will be necessary for human health and the environment. Iron (Fe is an essential nutrient for both plants and humans. Fe is poorly soluble, especially at high pH levels, at which it is difficult for living organisms to accumulate sufficient Fe. In plants, Fe deficiency leads to low yield and poor nutritional quality, as it significantly affects chlorophyll synthesis. Fe deficiency is a worldwide agricultural problem that is especially serious in soils with a high pH, such as calcareous soils, which comprise approximately 30% of cultivated soils worldwide. Genetic improvements in crops that can tolerate Fe deficiency will be required to meet the demands for crop production and could ultimately contribute to the amelioration of global warming. Nicotianamine (NA is an Fe chelator in plants that is involved in metal translocation in the plant body. In mammals, NA inhibits angiotensin I-converting enzyme, which plays a key role in blood pressure control. It was recently shown that the enhancement of NA production using nicotianamine synthase is useful for increasing not only NA but also Fe and Zn levels in crops such as rice, soybean, and sweet potato. Additionally, these plants showed Fe-deficiency tolerance in calcareous soil. These results suggested that NAS overexpression simultaneously improves food quality and increases plant production. This review summarizes progress in generating crops overexpressing NAS.

    Anabaena flos-aquae NRC-44-1 is a freshwater nitrogen fixing blue-green alga of some ecological significance because of its toxicity. In axenic culture and possibly also in nature, the alga is highly susceptible to lysis at certain stages of its growth. Nothing is known about genetic phenomena governing toxin production, nitrogen fixation or other characteristics of this organism, mainly because of unavailability of mutant strains that could be utilized in genetic experiments. With the object of overcoming this obstacle to the eventual study of genetics of Anabaena flos-aquae, attempts were made to produce and isolate nutritionally-deficient mutants of this species.

    Vegetarians and vegans are more vulnerable to vitamin B 12 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 B 12 are poorly absorbed. The present research evaluates the ability of two different sublingual dosages of vitamin B 12 (350 μg/week vs 2000 μg/week) in improving cyanocobalamin (vitamin B 12 ) nutritional status in vegans and vegetarians with a marginal deficiency. A 12-week randomized, double-blind, controlled, parallel intervention trial was performed. Forty subjects with marginal vitamin B 12 deficiency were enrolled and randomly divided into two groups: test group Ld (low dose, 350 μg/week) and control group Hd (high dose, 2000 μg/week) vitamin B 12 supplementation. Blood samples were collected at baseline and after 15, 30, 60, and 90 days from the intervention for the determination of vitamin B 12 , related metabolic markers, and blood cell counts. Two-way analysis of variance showed a significant effect of time (P < 0.0001) and of time × treatment interaction (P = 0.012) on serum concentration of vitamin B 12 that increased after 90-day supplementation (Ld and Hd) compared to baseline. Both the supplements increased (P < 0.0001, time effect) the levels of holotranscobalamin, succinic acid, methionine and wellness parameter, while decreased (P < 0.0001, time effect) the levels of methylmalonic acid, homocysteine and folate compared to baseline. No difference was observed between groups (LdvsHd). No effect was detected for vitamin B 6 and blood cell count. In our experimental conditions, both supplements were able to restore adequate serum concentrations of vitamin B 12 and to improve the levels of related metabolic blood markers in subjects with a marginal deficiency. The results support the use of a sublingual dosage of 50 μg/day (350

    Nutritional and metabolic complications can develop after Roux-en-Y gastric bypass (RYGB) when there is an exaggerated response to the anatomical and functional changes or when there is inadequate nutritional supplementation. Severe malnutrition is rare, but deficiencies of vitamin B12, iron, calcium and thiamin, metabolic bone disease and gallstones are common after RYGB. Shortage of vitamin B12, iron, calcium and also cholelithiasis are caused at least partially by excluding the duodenum and proximal jejunum from food transit. We designed a new procedure, with the maintenance of the duodenum and proximal jejunum in the gastrointestinal transit through interposition of jejunal loop, as a primary operation to prevent such deficiencies or as corrective surgery for severe malnutrition after RYGB with failure in responding to conservative treatment. Complicações nutricionais e metabólicas podem se desenvolver após a derivação gástrica em Y de Roux (DGYR) quando há uma resposta exagerada às mudanças anatômicas e funcionais ou quando há suplementação nutricional inadequada. A desnutrição grave é rara, mas deficiências de vitamina B12, ferro, cálcio e tiamina, doença óssea metabólica e cálculos biliares são comuns após a DGYR. Dessas deficiências mencionadas, a de vitamina B12, de ferro, de cálcio e também a colelitíase, são causadas, ao menos parcialmente, pela exclusão do duodeno e jejuno proximal. Um novo procedimento com a manutenção do duodeno e do jejuno proximal no trânsito gastrointestinal, mediante interposição de alça jejunal, foi idealizado como operação primária para prevenir essas deficiências ou como cirurgia corretiva de desnutrição grave após DGYR com falha na resposta a exaustivas tentativas de tratamento conservador.

    Introduction: We present data from the Korean National Health and Nutrition Examination Survey 2008–2009 on the distribution of blood cadmium levels and their association with iron deficiency in a representative sample of the adult Korean population. Methods: Serum ferritin was categorized into three levels: low (serum ferritin <15.0 μg/L), low normal (15.0–30.0 μg/L for women and 15.0–50.0 for men), and normal (≥30.0 μg/L for women and ≥50.0 for men), and its association with blood cadmium level was assessed after adjustment for various demographic and lifestyle factors. Results: Geometric means of blood cadmium in the low serum ferritin group in women, men, and all participants were significantly higher than in the normal group. Additionally, multiple regression analysis after adjusting for various covariates showed that blood cadmium was significantly higher in the low-ferritin group in women, men, and all participants compared with the normal group. We also found an association between serum ferritin and blood cadmium among never-smoking participants. Discussion: We found, similar to other recent population-based studies, an association between iron deficiency and increased blood cadmium in men and women, independent of smoking status. The results of the present study show that iron deficiency is associated with increased levels of blood cadmium in the general population.

    Pregnant rats were fed either a control (20% protein) or low (3.5%) protein diet during gestation and lactation. The pups were separated from their mothers on postnatal day 21, and were given the same dient as their corresponding mothers. The groups of pups from each diet group were treated on either postnatal day 21 or postnatal day 60 with 7.5 mg methylmercury chloride (MeHgCl) per kg b.w. once daily by gavage for 10 consecutive days, and the development of ataxia (hind-limb corossing) was monitored. The offspring from mothers on the protein-deficient diet were found to be more sensitive to MeHg-induced ataxia than those on the protein-sufficient diet. The former accumulated more mercury in different brain regions than the latter. The rates of protein synthesis in different brain regions of the offspring fed the protein-deficient diet were significantly reduced compared with the rates in those fed the protein-sufficient diet. However, MeHg treatment did not significantly modify the rates of such protein synthesis further in protein-deficient rats. Thus, a significantly much higher inhibition of the intrinsic rates of protein synthesis in different brain regions due to severe protein deficiency, as observed in this study, may be partly responsible for the increased susceptibility of developing rats fed a protein-deficient diet to MeHg-induced ataxia, or hindlimb crossing, although other factor(s) might also be involved.

    Full Text Available Taking into account the fact that in Ukraine today there is not enough researches that summarize the data on the nutritional status of young children, the prevalence of eating disorders and lack of basic macro- and micronutrients in children, the multicenter study on nutrition of children from 9 months to 3 years of life has been carried out. It was found that the present dietary intake of infants is unbalanced, contains excess energy and proteins, lack of zinc, iron, calcium, and vitamins A, D, E, B6, B12, B1. Due to unbalanced diet, the use of special infant formula instead of unmodified bovine milk in feeding young child can increase consumption of important nutrients (calcium, iron, iodine, vitamin E, D and folates.

    Full Text Available Taking into account the fact that in Ukraine today there is not enough researches that summarize the data on the nutritional status of young children, the prevalence of eating disorders and lack of basic macro- and micronutrients in children, the multicenter study on nutrition of children from 9 months to 3 years of life has been carried out. It was found that the present dietary intake of infants is unbalanced, contains excess energy and proteins, lack of zinc, iron, calcium, and vitamins A, D, E, B6, B12, B1. Due to unbalanced diet, the use of special infant formula instead of unmodified bovine milk in feeding young child can increase consumption of important nutrients (calcium, iron, iodine, vitamin E, D and folates.

    because consumers will avoid products that the label shows to be nutritionally deficient, but also because food producers will try to avoid marketing products that appear, according to the label, as nutritionally problematic, for example, because of a high content of saturated fat or salt. Nutrition......Nutrition labeling refers to the provision of information on a food product’s nutritional content on the package label. It can serve both public health and commercial purposes. From a public health perspective, the aim of nutrition labeling is to provide information that can enable consumers...... to make healthier choices when choosing food products. Nutrition labeling is thus closely linked to the notion of the informed consumer, that chooses products according to their aims, on the basis of the information at their disposal.

    Food-insecure pregnant females may be at greater risk of iron deficiency (ID) because nutrition needs increase and more resources are needed to secure food during pregnancy. This may result in a higher risk of infant low birth weight and possibly cognitive impairment in the neonate. The relationships of food insecurity and poverty income ratio (PIR) with iron intake and ID among pregnant females in the United States were investigated using National Health and Nutrition Examination Survey 1999-2010 data (n=1,045). Food security status was classified using the US Food Security Survey Module. One 24-hour dietary recall and a 30-day supplement recall were used to assess iron intake. Ferritin, soluble transferrin receptor, or total body iron classified ID. Difference of supplement intake prevalence, difference in mean iron intake, and association of ID and food security status or PIR were assessed using χ(2) analysis, Student t test, and logistic regression analysis (adjusted for age, race, survey year, PIR/food security status, education, parity, trimester, smoking, C-reactive protein level, and health insurance coverage), respectively. Mean dietary iron intake was similar among groups. Mean supplemental and total iron intake were lower, whereas odds of ID, classified by ferritin status, were 2.90 times higher for food-insecure pregnant females compared with food-secure pregnant females. Other indicators of ID were not associated with food security status. PIR was not associated with iron intake or ID. Food insecurity status may be a better indicator compared with income status to identify populations at whom to direct interventions aimed at improving access and education regarding iron-rich foods and supplements.

    2011-12-01

    The North American Institute of Medicine (IOM) recently published their report on dietary reference intakes (DRI) for Ca and vitamin D. The DRI committee's deliberations underpinning this most comprehensive report on vitamin D nutrition to date benefited hugely from a much expanded knowledge base in vitamin D over the last decade or more. However, since their release, the vitamin D DRI have been the subject of intense controversy, which is largely due to the persistence of fundamental knowledge gaps in vitamin D. These can be identified at the levels of exposure, metabolism, storage, status, dose-response, function and beneficial or adverse health effects, as well as safe and effective application of intake recommendations at the population level through sustainable food-based approaches. The present review provides a brief overview of the approach used by the IOM committee to revise the DRI for vitamin D and to collate from a number of authoritative sources key knowledge gaps in vitamin D nutrition from the public health perspective. A number of research topics are outlined and data requirements within these are identified and mapped to the risk assessment framework used by the DRI committee. While not intended as an exhaustive list, it provides a basis for organising and prioritising research efforts in the area of vitamin D, which may offer a perspective on the major areas in need of attention. It is intended to be of use to researchers, national policy makers, the public health community, industry groups and other relevant stakeholders including funding institutions.

    Iron deficiency anemia (IDA) is a global public health problem among school age children, which retards psychomotor development and impairs cognitive performance. There is limited data on prevalence and risk factors for IDA. The aim of this study was to determine the prevalence, severity, and predictors of nutritional IDA in school age children in Southwest Ethiopia. A community based cross-sectional study was conducted in Jimma Town, Southwest Ethiopia from April to July 2013. A total of 616 school children aged 6 to 12 years were included in the study using multistage sampling technique. A structured questionnaire was used to collect sociodemographic data. Five milliliter venous blood was collected from each child for hematological examinations. Anemia was defined as a hemoglobin level lower than 11.5 g/dl and 12 g/dl for age group of 5-11 years and 12-15 years, respectively. Iron deficiency anemia was defined when serum iron and ferritin levels are below 10 µmol/l and 15 µg/dl, respectively. Moreover, fresh stool specimen was collected for diagnosis of intestinal parasitic infection. Stained thick and thin blood films were examined for detection of Plasmodium infection and study of red blood cell morphology. Dietary patterns of the study subjects were assessed using food frequency questionnaire and anthropometric measurements were done. Data were analyzed using SPSS V-20.0 for windows. Overall, prevalence of anemia was 43.7%, and that of IDA was 37.4%. Not-consuming protein source foods [AOR = 2.30, 95%CI(1.04,5.14)], not-consuming dairy products [AOR = 1.83, 95%CI(1.14,5.14)], not-consuming discretionary calories [AOR = 2.77, 95%CI(1.42,5.40)], low family income [AOR = 6.14, 95%CI(2.90,12.9)] and intestinal parasitic infections [AOR = 1.45, 95%CI(1.23, 5. 27)] were predictors of IDA. Iron deficiency anemia is a moderate public health problem in the study site. Dietary deficiencies and intestinal parasitic infections were predictors of IDA

    2008-01-01

    Full Text Available Polymorphisms in genes encoding folate metabolizing enzymes have been linked to an increased risk of maternal chromosomal nondisjunction in several populations. With the purpose of evaluating this relationship, we compared the frequencies of 677C>T and 1298A>C polymorphisms in the methylenetetrahydrofolate reductase gene (MTHFR and 66A>G in the methionine synthase reductase gene (MTRR between 103 young mothers of Down syndrome (DS individuals and 108 control mothers, whose offspring was karyotypically normal, correlating it with an estimative of folate and – related micronutrients levels intake. Maternal and paternal transmission frequencies of MTHFR 677T allele were also examined to access potential parent-of-origin effects. PCR-RFLP for genomic DNA was accomplished and allele/genotype frequencies differences were determined using the x2 test, whereas pattern of transmission of the MTHFR 677 allele was analyzed by transmission disequilibrium test. None of the polymorphisms seemed to be more frequent in case mothers than in controls, either individually or combined. The estimative of nutritional intake revealed that folate consumption median was inadequate in both groups, whereas methionine and zinc consumption medians were significantly greater in control mothers. It suggests that such interaction between genetic profile and environment could predispose this sub group of women to have a DS child. Additional studies focusing the interaction between nutritional intakes, biochemical data and folate pathway polymorphisms are needed to confirm the present results. The possibility of neutralize the biochemical negative effects of folate-related polymorphisms through oral supplementation could provide new targets for DS prevention.

    Full Text Available Background : Vitamin D and calcium are important factors involved in the regulation of blood glucose and insulin secretion. The Homeostatic Model Assessment of Insulin Resistance (HOMA-IR score is a useful variable for evaluating insulin resistance, and therefore we cross-sectionally compared HOMA-IR scores according to serum vitamin D levels and dietary calcium intake. Methods : We selected data from healthy males (n=5,163 and females (n=7,506 analyzed over 5 years (2008–2012 via the Korea National Health and Nutrition Examination Survey (KNHANES. We calculated HOMA-IR scores and compared them according to serum 25-hydroxyvitamin D (25(OHD concentration classification (30 ng/mL and dietary calcium quintile after adjustment for relevant variables using complex sample analysis. Comparisons were done after data weighting. Results : The mean dietary calcium intake in males and females was 558.1 mg/day and 445.9 mg/day, respectively. The mean serum 25(OHD concentration in males and females was 19.4 ng/mL and 16.8 ng/mL, respectively. After adjustment for relevant variables, HOMA-IR score was significantly correlated with serum 25(OHD concentration and dietary calcium intake in females, whereas it was only correlated with serum 25(OHD concentration in males. HOMA-IR was significantly lower in the top quintile of dietary calcium intake (mean, 866 mg/day within females with vitamin D deficiency (P=0.047. Conclusion : Adequate dietary calcium intake may be important for normal HOMA-IR in females with vitamin D deficiency.

    This Study was conducted with the following objectives: 1.determine the prevalance of iron deficiency anaemia among pregnant women. 2. Determine the factors that affect the iron status of pregnant women (nutritional, social etc...). For the assessment of iron status during pregnancy, 30 healthy pregnant women were included in a longitudinal study from the first to the third trimester. One blood sample was taken in the first trimester and a second blood sample was taken in the third trimester. All subjects were given ten iron supplement tablets at the beginning of the study by the researcher. However, they did not receive any other iron supplements throughout their pregnancy. Ten healthy non-pregnant women were included in the study to serve as controls. The iron status was assessed using the following parameters: haemoglobin and serum ferritin levels which was measured using ImmunoRadiometric Assay (IRMA). The nutritional status was assessed from a nutritional/socio-economic questionnaire that was answered by the study and control groups. Both the study and the control groups had haemoglobin level below the WHO cut-off points ( 0.05) between the level of haemoglobin of control and the study groups in the first and third trimester. There was significant difference (p<0.01) in the level of serum ferritin between the study and control group. The study group had a higher level of serum ferritin than the control. there was also high significant difference (p<0.01) in the level of serum ferritin between the first and third trimester in which a large decrease in the level of serum ferritin was apparent. The results of this study also showed that 16.5% had IDA (Iron Defeciency Anaemia) in the first trimester whereas 27.6% had depleted iron stores without frank defeciency. The prevalance of IDA increased to 26.4% in the third trimester while those who had depleted iron stores increased to 46.6%. Almost 50% of pregnant women started their pregnancy with adequate iron stores

    2002-01-01

    From a global perspective and in spite of decades of nutrition programmes, micronutrients deficiency is at alarming proportions in many developing societies today. It affects millions of people worldwide, and includes consequences that potentially compromise morbidity, mortality, cognitive development, and growth, reproductive and work capacity. Recent estimates by the WHO are that deficiencies of iron (Fe), iodine (I), and vitamin A continue to influence the health of 2000 million, 740 million, and 250 million persons respectively. In addition to these three micronutrients, the possible negative consequences of deficiencies of zinc (Zn), copper (Cu) and selenium (Se) are now also being increasingly recognized as important health concerns. As a result of the increasing recognition of the co-existence of multiple micronutrient deficiencies in developing countries, United Nations Agencies have urged that supplementation, fortification and dietary modification/diversification programmes are designed to combat multiple micronutrient deficiencies simultaneously. Fortificant levels for fortification, like supplementation, must be carefully selected to minimize risk of antagonistic nutrient interactions and to take into account the toxic threshold level for normal individuals. Possible antagonistic interactions that may interfere with the utilisation of trace elements in the supplements or fortificants per se, and/or with the utilization of elements intrinsic to the food or the meal include those between Cu-Zn, Cu-Fe, Fe-Zn, Mn-Fe, Ca-Zn. Stable isotope techniques play an important role in quantifying the optimal levels and the bioavailability of micronutrient supplements and fortificants for a range of indigenous meals consumed in developing countries, especially those containing potent absorption inhibitors. This Capacity building CRP or Thermatic CRP (T-CRP) addresses the need to develop effective strategies to combat micro-nutrient malnutrition in developing countries

    Targeted gene expression using quantitative reverse transcription polymerase chain reaction (qRT-PCR) was employed to track patterns in the expression of genes indicative of nitrogen or phosphorus deficiency in the brown tide-forming alga Aureococcus anophagefferens. During culture experiments, a xanthine/uracil/vitamin C permease (XUV) was upregulated ∼20-fold under nitrogen-deficient conditions relative to a nitrogen-replete control and rapidly returned to nitrogen-replete levels after nitrogen-deficient cells were resupplied with nitrate or ammonium. It was not responsive to phosphorus deficiency. Expression of an inorganic phosphate transporter (PTA3) was enriched ∼10-fold under phosphorus-deficient conditions relative to a phosphorus-replete control, and this signal was rapidly lost upon phosphate resupply. PTA3 was not upregulated by nitrogen deficiency. Natural A. anophagefferens populations from a dense brown tide that occurred in Long Island, NY, in 2009 were assayed for XUV and PTA3 expression and compared with nutrient concentrations over the peak of a bloom. Patterns in XUV expression were consistent with nitrogen-replete growth, never reaching the values observed in N-deficient cultures. PTA3 expression was highest prior to peak bloom stages, reaching expression levels within the range of P-deficient cultures. These data highlight the value of molecular-level assessments of nutrient deficiency and suggest that phosphorus deficiency could play a role in the dynamics of destructive A. anophagefferens blooms. © 2013 Society for Applied Microbiology and John Wiley & Sons Ltd.

    India has achieved self-sufficiency in the production of food grains, yet the production of milk, legumes, vegetables, oils and fats, eggs, and meat is far short of the needs of the population. The Indian diet predominantly comprises cereals, and the diets of expectant and nursing mothers as well as children are grossly deficient in protective foods. Serious nutritional inadequacies have resulted in low birth weight, retarded growth, and nutritional deficiencies (protein energy malnutrition in preschool children, vitamin A deficiency, iron deficiency in women of reproductive age, and iodine deficiency disorders among neonates and schoolchildren). General malnutrition is prevalent in 25% of the rural and 20% of the urban population. Deficiency symptoms of vitamin B complex and vitamin C are also not uncommon. 37% of the population of India lives below the poverty limit, the literacy rate is only 52.1% (39.4% for women), safe drinking water is scarce, nutritional ignorance is rampant, there is a lack of personal hygiene, and poor sanitation all account for malnutrition. A number of government and nongovernmental organizations' programs have attempted to raise the level of nutrition and the standard of living of the people. Some of them include the integrated child development services, special nutritional program, national vitamin A deficiency prophylaxis program, national anemia prophylaxis program, national goiter control program, midday meal program, special class feeding programs, universal immunization program, nutritional and health education through the mass media as well as the observance of world food day and world health day. The national health policy gives high priority to the promotion of family planning, the provision of primary health care, and the acceleration of welfare programs for women and children. As a result of policies and programs of health and nutrition, the infant, child, and maternal mortality rates have declined and life expectancy at

    Full Text Available Ignacio Jáuregui-Lobera Department of Nutrition and Bromatology, Pablo de Olavide University, Seville, Spain Abstract: Micronutrient deficiencies, especially those related to iodine and iron, are linked to different cognitive impairments, as well as to potential long-term behavioral changes. Among the cognitive impairments caused by iron deficiency, those referring to attention span, intelligence, and sensory perception functions are mainly cited, as well as those associated with emotions and behavior, often directly related to the presence of iron deficiency anemia. In addition, iron deficiency without anemia may cause cognitive disturbances. At present, the prevalence of iron deficiency and iron deficiency anemia is 2%–6% among European children. Given the importance of iron deficiency relative to proper cognitive development and the alterations that can persist through adulthood as a result of this deficiency, the objective of this study was to review the current state of knowledge about this health problem. The relevance of iron deficiency and iron deficiency anemia, the distinction between the cognitive consequences of iron deficiency and those affecting specifically cognitive development, and the debate about the utility of iron supplements are the most relevant and controversial topics. Despite there being methodological differences among studies, there is some evidence that iron supplementation improves cognitive functions. Nevertheless, this must be confirmed by means of adequate follow-up studies among different groups. Keywords: iron deficiency, anemia, cognitive functions, supplementation

    Full Text Available OBJETIVO: Comparar o estado nutricional e a prevalência de carência de ferro em crianças freqüentadoras de creche antes e 15 meses após orientação nutricional e intervenção terapêutica. MÉTODOS: Estudo coorte com 52 crianças de 32 a 78 meses de idade, freqüentadoras de uma creche em Catanduva, São Paulo, avaliadas em dois períodos: antes e 15 meses após receberem tratamento para anemia e correção das alterações no estado nutricional. O estado nutricional das crianças foi avaliado por meio da curva da Organização Mundial de Saúde (2006. O diagnóstico de carência de ferro foi realizado por dosagem de hemoglobina e nível de ferritina sérica. Dados adicionais das crianças não eutróficas foram obtidos por meio de entrevistas com suas mães. RESULTADOS: Observou-se 2% de desnutrição aguda e 8% de obesidade, não havendo diferença significante entre os dois períodos. 12% das crianças apresentaram anemia, havendo diminuição do número de crianças com anemia após o tratamento. Dois novos casos de obesidade e cinco de carência de ferro surgiram durante o período de intervenção nutricional. Das oito crianças com alterações nutricionais no período inicial, 63% das mães procuraram atendimento médico para tratamento. CONCLUSÕES: O tratamento dos distúrbios nutricionais e da carência de ferro diminuiu o número de crianças afetadas. O aparecimento de novos casos de obesidade e anemia serve de alerta para a necessidade de outras medidas preventivas tanto na creche como no âmbito familiar.OBJECTIVE: To compare the nutritional status and the prevalence of iron deficiency among children enrolled in a day care center before and after 15 months of nutritional management.

    Since vitamin B12 occurs in substantial amounts only in foods derived from animals, vegetarians and particularly vegans are at risk of developing deficiencies of this essential vitamin. The chlorella used for this study is a commercially available whole-food supplement, which is believed to contain the physiologically active form of the vitamin. This exploratory open-label study was performed to determine if adding 9 g of Chlorella pyrenoidosa daily could help mitigate a vitamin B12 deficiency in vegetarians and vegans. Seventeen vegan or vegetarian adults (26-57 years of age) with a known vitamin B12 deficiency, as evidenced by a baseline serum methylmalonic acid (MMA) level above 270 nmol/L at screening, but who otherwise appeared healthy were enrolled in the study. Each participant added 9 g of C. pyrenoidosa to their daily diet for 60 ± 5 days and their serum MMA, vitamin B12, homocysteine (Hcy) levels as well as mean corpuscular volume (MCV), hemoglobin (Hgb), and hematocrit (Hct) were measured at 30 and 60 days from baseline. After 30 and 60 days, the serum MMA level fell significantly (P < .05) by an average ∼34%. Fifteen of the 17 (88%) subjects showed at least a 10% drop in MMA. At the same time, Hcy trended downward and serum vitamin B12 trended upward, while MCV, Hgb, and Hct appeared unchanged. The results of this work suggest that the vitamin B12 in chlorella is bioavailable and such dietary supplementation is a natural way for vegetarians and vegans to get the vitamin B12 they need.

    To characterize the gestational changes of iodine nutrition and thyroid function and to explore the factors associated with the thyroid function in pregnant women. A longitudinal survey was conducted in 130 pregnant women in Luohe city of Henan province from October 2012 to May 2013. Samples of fasting blood and urine were collected in each trimester to test on thyroid function and urinary iodine. Data regarding social demography and lifestyle behavior were collected through questionnaire in the first trimester. The medians of urinary iodine (MUI) for pregnant women were 238.9, 150.8 and 306.4 µg/L in the first, second and third trimesters, respectively (P 0.05) but the level of free thyroxine (FT4) decreased (P iodine nutrition and thyroid function. With the increase of iodine level, the level of TSH first increased and then decreased while the levels of FT3 and FT4 showed the opposite trend. The level of TSH was influenced by factors as education level, history of chronic diseases, history of CT and X-ray examination, and intake of pickled food etc. The level of FT4 was associated with residence (urban or rural), stressful events in the previous year, daily means of transportation, and the hours of sedentariness, working and sleeping. Significant differences were noticed in iodine nutrition and thyroid function of pregnant women during the three trimesters. It was essential to establish specific reference ranges for different trimesters. Thyroid functions of pregnant women seemed to be associated with iodine level and lifestyle.

  12. Differences in gorilla nettle-feeding between captivity and the wild: local traditions, species typical behaviors or merely the result of nutritional deficiencies?

    Science.gov (United States)

    2011-11-01

    Behavioral and cognitive studies on captive apes often pay little attention to the specific environmental conditions of their study subjects. A recent report form Byrne et al. (Anim Cogn doi: 10.1007/s10071-011-0403-8, 2011), comparing nettle-feeding techniques between captive and wild gorillas, claimed to document "the strongest evidence yet to come from any great ape that observational learning of a skilled conspecific" can allow social learning and culture in gorillas. An earlier study with similar findings placed emphasis instead on the many similarities and claims for species typical behavior, thus a genetic hypothesis instead of a cultural hypothesis. This commentary aims at formulating a third environmental hypothesis based on path-dependent behavioral differences owing to different diet and availability of nutritional resources of wild and captive gorillas. Captive diet provides gorillas with a much lower concentration of fibers. Gorillas are hindgut fermenters, and this deficit of natural fermentation of fibers may impact their health and their behavior in zoos. Results of Byrne et al.'s study will be discussed comparing feeding choice and availability of nutritional resources of wild and captive gorillas, showing that in captivity gorilla, motivation to consume certain food or certain plant parts may differ drastically from that of wild gorillas. This view does not intend to deny that social learning and culture may exist in gorillas, but to guide and encourage future works investigating social learning in great apes to take more accurately into account the living conditions and, when comparing populations, the possible environmental differences. © Springer-Verlag 2011

    This study describes clinical, laboratory, and electrodiagnostic features of a severe acute axonal polyneuropathy common to patients with acute nutritional deficiency in the setting of alcoholism, bariatric surgery (BS), or anorexia. Retrospective analysis of clinical, electrodiagnostic, and laboratory data of patients with acute axonal neuropathy. Thirteen patients were identified with a severe, painful, sensory or sensorimotor axonal polyneuropathy that developed over 2-12 weeks with sensory ataxia, areflexia, variable muscle weakness, poor nutritional status, and weight loss, often with prolonged vomiting and normal cerebrospinal fluid protein. Vitamin B6 was low in half and thiamine was low in all patients when obtained before supplementation. Patients improved with weight gain and vitamin supplementation, with motor greater than sensory recovery. We suggest that acute or subacute axonal neuropathy in patients with weight loss or vomiting associated with alcohol abuse, BS, or dietary deficiency is one syndrome, caused by micronutrient deficiencies.

    The topic "nutrition and the eye" cannot adequately be covered in a single review article; indeed, dozens of books and hundreds of articles have been written on the subject. This review concentrates on three areas in which specific nutrients are known or theorized to have a major impact on vision and the visual system: vitamin A deficiency; antioxidants and their proposed role in the prevention of age-related cataract and macular degeneration; and nutritional optic neuropathies, including those of the recent Cuban epidemic. In addition, this article touches on nutritional treatments that have been suggested for several less common eye diseases and, finally, considers several less prevalent conditions in which deficiency of or excess exposure to a particular nutrient has been associated with ocular pathology.

    1978-05-01

    Recent studies of experimental vitamin A deficiency in man led the authors to conclude that anemia may result from lack of vitamin A. A review of numerous nutrition surveys in underdeveloped countries enhanced the suspicion that deficiency of vitamin A does contribute to the prevalence of anemia. Preliminary studies of vitamin A-deficient rats confirmed previous observations that anemia may result from lack of this vitamin. The livers of these animals had very low concentrations of vitamin A but normal or increased concentrations of iron. The finding of anemia is in contrast with other reports that vitamin A deficiency may cause elevated values for hemoglobin and hematocrit. The authors suggest that loss of taste and smell as a result of deficiency may account for refusal of experimental animals to eat and drink enough to prevent inanitation and dehydration. The resulting hemoconcentration may mask the true hematological picture, which is one of anemia.

    It is a strong and commonly held belief among nutrition clinicians that enteral nutrition is preferable to parenteral nutrition. We provide a narrative review of more recent studies and technical reviews comparing enteral nutrition with parenteral nutrition. Despite significant weaknesses in the existing data, current literature continues to support the use of enteral nutrition in patients requiring nutrition support, over parenteral nutrition.

    2018-04-01

    Nutritional deficiencies in plants are a major concern for farmers as it affects productivity and thus profit. The work aims to classify nutritional deficiencies in maize plant in a non-destructive mannerusing image processing and machine learning techniques. The colored images of the leaves are analyzed and classified with multi-class support vector machine (SVM) method. Several images of maize leaves with known deficiencies like nitrogen, phosphorous and potassium (NPK) are used to train the SVM classifier prior to the classification of test images. The results show that the method was able to classify and identify nutritional deficiencies.

  15. Tuberculosis and nutrition

    Full Text Available Malnutrition and tuberculosis are both problems of considerable magnitude in most of the underdeveloped regions of the world. These two problems tend to interact with each other. Tuberculosis mortality rates in different economic groups in a community tend to vary inversely with their economic levels. Similarly, nutritional status is significantly lower in patients with active tuberculosis compared with healthy controls. Malnutrition can lead to secondary immunodeficiency that increases the host′s susceptibility to infection. In patients with tuberculosis, it leads to reduction in appetite, nutrient malabsorption, micronutrient malabsorption, and altered metabolism leading to wasting. Both, protein-energy malnutrition and micronutrients deficiencies increase the risk of tuberculosis. It has been found that malnourished tuberculosis patients have delayed recovery and higher mortality rates than well-nourished patients. Nutritional status of patients improves during tuberculosis chemotherapy. High prevalence of human immunodeficiency (HIV infection in the underdeveloped countries further aggravates the problem of malnutrition and tuberculosis. Effect of malnutrition on childhood tuberculosis and tuberculin skin test are other important considerations. Nutritional supplementation may represent a novel approach for fast recovery in tuberculosis patients. In addition, raising nutritional status of population may prove to be an effective measure to control tuberculosis in underdeveloped areas of world.

    Weight loss and malnutrition are common in cancer patients. Although weight loss is predominantly due to loss of fat mass, the morbidity risk is given by the decrease in muscle mass. The assessment of nutritional status is essential for a diagnosis of nutritional compromise and required for the multidisciplinary approach. Subjective global assessment (SGA) is made by the patients nutritional symptoms and weight loss. The objective assessment, a significant weight loss (>10%) for 6 months is considered an indicator of nutritional deficiency. The mean body index, body fat mass and body protein mass are decreased as cancer stage increases. The biochemical data of albumin, cholesterol, triglyceride, Zn, transferrin, total lymphocyte count are decreased in advanced cancer stage. Daily energy intake, cabohyderate and Vit B1 intake is decreased according to cancer stage. The patients are divided into three groups according to SGA. The three groups showed a significant difference in body weight, 1 month weight loss%, 6 month weight loss%, body mass index, mid arm circumference, albumin, energy intake, as well as carbohyderate intake protein and energy malnutrition. Nutritional assessment is of great importance because undernutrition has been shown to be associated with increase in stomach cancer associated morbidity and mortality. The authors concluded that nutritional assessment should be done in cancer patients preoperatively, and with adequate nutritional support, the morbidity and mortality would be decreased.

    Vitamin and mineral deficiencies adversely affect a third of the world's people. Consequently, a series of global goals and a serious amount of donor and national resources have been directed at such micronutrient deficiencies. Drawing on the extensive experience of the authors in a variety of institutional settings, the article used a computer search of the published scientific literature of the topic, supplemented by reports and published and unpublished work from the various agencies. In examining the effect of sex on the economic and social costs of micronutrient deficiencies, the paper found that: (1) micronutrient deficiencies affect global health outcomes; (2) micronutrient deficiencies incur substantial economic costs; (3) health and nutrition outcomes are affected by sex; (4) micronutrient deficiencies are affected by sex, but this is often culturally specific; and finally, (5) the social and economic costs of micronutrient deficiencies, with particular reference to women and female adolescents and children, are likely to be considerable but are not well quantified. Given the potential impact on reducing infant and child mortality, reducing maternal mortality, and enhancing neuro-intellectual development and growth, the right of women and children to adequate food and nutrition should more explicitly reflect their special requirements in terms of micronutrients. The positive impact of alleviating micronutrient malnutrition on physical activity, education and productivity, and hence on national economies suggests that there is also an urgent need for increased effort to demonstrate the cost of these deficiencies, as well as the benefits of addressing them, especially compared with other health and nutrition interventions.

    2004-06-01

    In the last 20 years, Public Health Nutrition focused mainly on the qualitative aspects which may influence the onset of chronic diseases, quality of life, physical and mental performance and life expectancy. This applied knowledge organised as part of preventive and health promotion programs led to the development of Community Nutrition. The aim of Community Nutrition actions is to adequate lifestyles related to food consumption patterns in order to improve the quality of life and contribute to health promotion of the population in the community where programs and services are delivered. Key functions to develop in a Community Nutrition Unit consist in the identification and assessment of nutrition problems in the community as well as the design, implementation and evaluation of intervention programs by means of appropriate strategies. These should aim at different populations groups and settings, such as work places, schools, high risk groups or the general public. Nowadays, Community Nutrition work efforts should focus on three main aspects: nutrition education in schools and in the community; food safety and food security and the development and reinforcement of food preparation skills across all age groups. Social catering services, either in schools, the work place or at the community level, need to ensure adequate nutritional supply, provide foods contributing to healthy eating practices as well as to enhance culinary traditions and social learning. Food safety and food security have become a top priority in Public Health. The concepts referes to the availability of food safe and adequate as well as in sufficient amount in order to satisfy nutrition requirements of all individuals in the community. Social changes along new scientific developments will introduce new demands in Community Nutrition work and individual dietary counselling will become a key strategy. In order to face new challenges, community nutrition pactitioners require a high quality

    2017-09-01

    Enteral nutrition is widely used in hospitals as a means of nutritional support and therapy for different diseases. Enteral nutrition must fulfil the energy needs of the body, be balanced by the nutrient composition and meet patient’s nutritional needs. Meat is a source of full-value animal protein, vitamins and minerals. On the basis of this research, recipes and technology for a meat-based enteral nutrition product were developed. The product is a ready-to-eat sterilised mixture in the form of a liquid homogeneous mass, which is of full value in terms of composition and enriched with vitamins and minerals, consists of particles with a size of not more than 0.3 mm and has the modified fat composition and rheological characteristics that are necessary for passage through enteral feeding tubes. The study presents experimental data on the content of the main macro- and micro-nutrients in the developed product. The new product is characterised by a balanced fatty acid composition, which plays an important role in correction of lipid metabolism disorders and protein-energy deficiency, and it is capable of satisfying patients’ daily requirements for vitamins and the main macro- and microelements when consuming 1500-2000 ml. Meat-based enteral nutrition can be used in diets as a standard mixture for effective correction of the energy and anabolic requirements of the body and support of the nutritional status of patients, including those with operated stomach syndrome.

    Full Text Available Due to higher energy consumption, physically active people have higher nutritional requirements. In addition to other important factors for sports, such as good health and physical predisposition, adequate nutrition is a fundamental component. Sports nutrition must be well planned and individually adapted based on physical characteristics, tendencies towards gaining or losing weight, frequency, duration and intensity of training sessions. Studies have shown that a well-balanced ratio of macro and micronutrients, with the support of supplements and adequate hydration, can significantly improve athletic performance and plays a key role in achieving better results. An optimally designed nutritional program, with realistic and achievable goals, which complements a well-planned training program, is the basis for success in sports. Only when nutritional requirements are met, deficits can be prevented and performance in sport pushed to the limit.

    Worldwide, nutritional rickets continues to be an evolving problem with several causes. This paper provides an updated literature review characterising the prevalence, aetiology, pathophysiology and treatment of nutritional rickets worldwide. A systematic review of articles on nutritional rickets from various geographical regions was undertaken. For each region, key information was extracted, including prevalence, cause of rickets specific to the region, methods of confirming the diagnosis and current treatment and preventive measures. Calcium deficiency continues to be a major cause of rickets in Africa and Asia. Vitamin D deficiency rickets is perhaps increasing in the Americas, Europe and parts of the Middle East. There continues to be a distinct presentation of calcium-predominant versus vitamin D predominant rickets, although there are overlapping features. More careful diagnosis of rickets and reporting of 25-OHD concentrations has improved accurate knowledge of rickets prevalence and better delineated the cause. Nutritional rickets continues to be an evolving and multi-factorial problem worldwide. It is on a spectrum, ranging from isolated vitamin D deficiency to isolated calcium deficiency. Specific areas which require emphasis include a consistent community approach to screening and diagnosis, vitamin D supplementation of infants and at-risk children, prevention of maternal vitamin D deficiency and the provision of calcium in areas with low calcium diets.

    Full Text Available In northeast Brazil, nutritional deficiency diseases and schistosomiasis mansoni overlap. An experimental model, wich reproduces the marasmatic clinical form of protein-energy malnutrition, was developed in this laboratory to study these interactions. Albino Swiss mice were fed with a food association ingested usually by human populations in northeast Brazil. This diet (Regional Basic Diet - RBD has negative effects on the growth, food intake and protein utilization in infected mice (acute phase of murine schistosomiasis. Nitrogen balance studies have also shown that infection with Schistosoma mansoni has apparently no effect on protein intestinal absorption in well nourished mice. However, the lowest absorption ratios have been detected among RBD - fed infected animals, suggesting that suprerimposed schistosome infection aggravated the nutritional status of the undernourished host. The serum proteins electrophoretic pattern, as far as albumins are concerned, is quite similar for non-infected undernourished and infected well-fed animals. So, the significance of albumins as a biochemical indicator of the nutritional status of human populations residing in endemic foci of Manson's schistosomiasis, is discussable.

    In most developing countries, nutritional rickets is a major health problem. The aim of this study was to explore the magnitude of nutritional rickets among Saudi infants, and the various clinical presentations, as well as to address the possible operating risk factors behind the disease. We carried out a retrospective study at King Abdulaziz Medical City-King Fahad National Guard Hospital in Riyadh, Saudi Arabia. The records of Saudi infants under the age of 14 months over a 10-year period (between January 1990 and January 2000) were reviewed. Information collected included age, sex, clinical presentations, biochemical, radiological findings, infant nutrition, presence of other nutritional deficiencies and exposure to sunlight. There were 283 infants diagnosed with nutritional rickets due to Vitamin D deficiency (67% males) who were between 6 and 14 months of age. Among the total, 70% were exclusively breast-fed, and 23% were breast-fed until the age of 1 year. The most frequent clinical presentation was hypo-calcemic convulsions (34%) followed by chest infections (33%) and gastroenteritis (25%). In conclusion, nutritional rickets is still prevalent in Saudi Arabia with the primary etiology being vitamin D deficiency. Therefore we recommend that every infant, who is exclusively on breast-feeding, has routine supplement of vitamin D in the range of 200 IU/day (alone or as apart of multivitamin), started soon after birth until the time of weaning.

    2013-06-01

    Nutritional rickets remains a public health concern in many areas of the world despite cheap and effective means of preventing the disease. The roles of vitamin D deficiency, low dietary calcium intakes and the interrelationships between the two in the pathogenesis of the disease are discussed. It is now recognized that vitamin D deficiency in the pregnant and lactating mother predisposes to the development of rickets in the breastfed infant, and that cultural and social factors are important in the pathogenesis of the disease during the adolescent growth spurt. Prevention of rickets is dependent on the awareness of the medical profession and the general public of the need to ensure adequate intakes of vitamin D in at-risk populations, and of the importance of increasing dietary intakes of calcium using locally available and inexpensive foods in communities in which dietary calcium deficiency rickets is prevalent.

    Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

    Nutritional rickets is a major public health problem in many countries of the world. The disease is characterized by deformities of the long bones, enlargement of the wrists and costochondral junctions, hypotonia and, in infants, craniotabes and delayed fontanelle closure. Predominantly caused by severe vitamin D deficiency, rickets can also be associated with hypocalcemic seizures and cardiac failure. First presentation is typically at 6-24 months of age, although hypocalcemia may be evident in younger infants. In many affluent industrialized countries, the prevalence of rickets in the general population diminished after the introduction of clean-air legislation and dietary supplementation. However, in such countries, vitamin-D deficiency rickets has re-emerged in recent years, particularly among groups with limited exposure to UVB-containing sunshine. Infants at risk of rickets tend to be those whose mothers had poor vitamin D status during pregnancy and those exclusively breast-fed for a prolonged period with little skin exposure to UVB. In other countries of the world, the prevalence of rickets can be high, even in regions with abundant year-round UVB-containing sunshine. In general, this is also due to vitamin D deficiency related to limited sun exposure. However, reports from Africa and Asia suggest that there may be other etiological factors involved. Studies in South Africa, Nigeria, The Gambia and Bangladesh have identified rickets in children, typically 3-5 years old at first presentation, in whom plasma 25-hydroxyvitamin D concentrations are higher than those characteristic of primary vitamin D deficiency. Calcium deficiency has been implicated, and in some, but not all, disturbances of phosphate metabolism, renal compromise and iron deficiency may also be involved. Continuing studies of the etiology of nutritional rickets will provide evidence to underpin guidelines for the prevention and treatment of rickets world-wide. This article is part of a

  12. Nutritional surveillance.

    Science.gov (United States)

    Mason, J B; Mitchell, J T

    1983-01-01

    The concept of nutritional surveillance is derived from disease surveillance, and means "to watch over nutrition, in order to make decisions that lead to improvements in nutrition in populations". Three distinct objectives have been defined for surveillance systems, primarily in relation to problems of malnutrition in developing countries: to aid long-term planning in health and development; to provide input for programme management and evaluation; and to give timely warning of the need for intervention to prevent critical deteriorations in food consumption. Decisions affecting nutrition are made at various administrative levels, and the uses of different types of nutritional surveillance information can be related to national policies, development programmes, public health and nutrition programmes, and timely warning and intervention programmes. The information should answer specific questions, for example concerning the nutritional status and trends of particular population groups.Defining the uses and users of the information is the first essential step in designing a system; this is illustrated with reference to agricultural and rural development planning, the health sector, and nutrition and social welfare programmes. The most usual data outputs are nutritional outcome indicators (e.g., prevalence of malnutrition among preschool children), disaggregated by descriptive or classifying variables, of which the commonest is simply administrative area. Often, additional "status" indicators, such as quality of housing or water supply, are presented at the same time. On the other hand, timely warning requires earlier indicators of the possibility of nutritional deterioration, and agricultural indicators are often the most appropriate.DATA COME FROM TWO MAIN TYPES OF SOURCE: administrative (e.g., clinics and schools) and household sample surveys. Each source has its own advantages and disadvantages: for example, administrative data often already exist, and can be

    Bunce, George E

    2005-05-01

    Participation of the author in the Interdepartmental Committee on Nutrition for National Defense sponsored nutrition surveys of Burma and northeast Brazil is described. These surveys not only collected important data on nutritional status but also guided the subsequent research interests of the author. The Brazil survey results contributed to the creation of legislation that mandated the addition of water-dispersible vitamin A to skimmed-milk powder products. This additive has greatly diminished the likelihood of vitamin A deficiency syndrome occurring in children after famine relief efforts.

  16. Osteomalacia as a result of vitamin D deficiency.

    Bhan, Arti; Rao, Ajay D; Rao, D Sudhaker

    2010-06-01

    Osteomalacia is an end-stage bone disease of chronic and severe vitamin D or phosphate depletion of any cause. Its importance has increased because of the rising incidence of vitamin D deficiency. Yet, not all cases of osteomalacia are cured by vitamin D replacement, and furthermore, not all individuals with vitamin D deficiency develop osteomalacia. Although in the past osteomalacia was commonly caused by malabsorption, nutritional deficiency now is more common. In addition, recent literature suggests that nutritional vitamin D deficiency osteomalacia follows various bariatric surgeries for morbid obesity. Bone pain, tenderness, muscle weakness, and difficulty walking are all common clinical manifestations of osteomalacia. Diagnostic work-up involves biochemical assessment of vitamin D status and may also include a transiliac bone biopsy. Treatment is based on aggressive vitamin D repletion in most cases with follow-up biopsies if patients are started on antiresorptive or anabolic agents. Copyright 2010 Elsevier Inc.

    Systemic sclerosis (SSc) is a chronic multisystem autoimmune disease which involves the gastrointestinal tract in about 90% of cases. It may contribute to nutritional deterioration. To assess whether the application of a nutritional support protocol to these patients could improve their nutritional status and quality of life. Single center prospective study, performed on an outpatient basis, in a county hospital. The Malnutrition Universal Screening Tool (MUST) was used to screen risk for malnutrition. Health questionnaire SF-36 and the Hospital Anxiety and Depression Scale were used to assess quality of life and psychopathology respectively. Weight, height, energy and protein requirements, macronutrient intake and nutritional biochemical parameters were evaluated. Nutritional intervention was performed in patients at risk for malnutrition. Of the 72 patients, 12.5% were at risk for malnutrition. Iron deficiency anemia (18.35%) and vitamin D deficiency (54%) were the most frequently observed nutritional deficits. The questionnaires on psychopathology and quality of life showed a high prevalence of anxiety and depression, and lower level poor quality of life in the physical and mental component. No significant improvements were observed in the weight, food intake, nutritional biochemical parameters, psychopathology and quality of life follow-up. Dietary intervention was able to maintain body weight and food intake. Iron deficiency anemia and vitamin D deficiency improved with iron and vitamine D supplements. No deterioration was observed in psychological assessment or quality of life. Studies with larger numbers of patients are needed to assess the efficacy of this intervention.

    Full Text Available We present two cases of carnitine deficiency in pregnancy. In our first case, systematic screening revealed L-carnitine deficiency in the first born of an asymptomatic mother. In the course of her second pregnancy, maternal carnitine levels showed a deficiency as well. In a second case, a mother known with carnitine deficiency under supplementation was followed throughout her pregnancy. Both pregnancies had an uneventful outcome. Because carnitine deficiency can have serious complications, supplementation with carnitine is advised. This supplementation should be continued throughout pregnancy according to plasma concentrations.

    2015-03-01

    Over the last 50 years, parenteral nutrition has been recognised as an invaluable and potentially lifesaving tool in the physician's arsenal in the management of patients with intestinal failure or inaccessibility; however, it may also be associated with a number of potentially life-threatening complications. A recent NCEPOD report (2010) identified a number of inadequacies in the overall provision and management of parenteral nutrition and recommendations were made with the aim of improving clinical practice in the future. This paper focuses on the practical aspects relating to parenteral nutrition for adults, including important concepts, such as patient selection, as well as general management. We also explore the various pitfalls and potential complications and how these may be minimised.

    Selenium deficient barley grown in Northern Ireland was treated with sodium hydroxide to deplete it of vitamin E. Housed cattle fed a complete diet based on this treated barley developed nutritional degenerative myopathy, showing that spontaneous myopathy in yearling cattle can be the result of vitamin E and selenium deficiency alone. The diet used is as effective and cheaper than others presently in use for inducing degenerative myopathy.

    Malnutrition during pregnancy adversely affects postnatal forebrain development; its effect upon brain stem development is less certain. To evaluate the role of tryptophan [critical for serotonin (5-HT) synthesis] on brain stem 5-HT and the development of cardiorespiratory function, we fed dams a diet ∼45% deficient in tryptophan during gestation and early postnatal life and studied cardiorespiratory variables in the developing pups. Deficient pups were of normal weight at postnatal day (P)5 but weighed less than control pups at P15 and P25 (P interactions between nutrition, brain stem physiology, and age that are potentially relevant to understanding 5-HT deficiency in the sudden infant death syndrome.

    Inappropriate food behavior contributes to obesity and leads to vitamin deficiency. This review discusses the nutritional status of water- and fat-soluble vitamins in obese subjects. We verified that most vitamins are deficient in obese individuals, especially the fat-soluble vitamins, folic acid, vitamin B 12 and vitamin C. However, some vitamins have been less evaluated in cases of obesity. The adipose tissue is considered a metabolic and endocrine organ, which in excess leads to changes in body homeostasis, as well as vitamin deficiency which can aggravate the pathological state. Therefore, the evaluation of vitamin status is of fundamental importance in obese individuals.

    The economic situation of Indonesia is characterized by a large increase in the gross national product which has been on average 7% annually during the last ten years. This was accompanied by rapid urbanization. With the economic improvement, "First World" and "Third World" health and nutrition problems are coexisting in Indonesia. In 1992, the most common of death cause was cardiovascular disease whereas tuberculosis was the second ranking. About 40% of the preschool children are stunted. The main stable food and energy source is rice, although the urban population has a more diverse food pattern than the rural population. In Jakarta, many children receive too late colostrum feeding and mothers are not aware about the importance of correct breastfeeding practices after delivery. Three studies had shown that about one fifth of preschool children and one fourth of elderly take micronutrient supplements. Nevertheless, micronutrient deficiencies are prevalent in Jakarta.

    Prado, Elizabeth L; Dewey, Kathryn G

    2014-04-01

    Presented here is an overview of the pathway from early nutrient deficiency to long-term brain function, cognition, and productivity, focusing on research from low- and middle-income countries. Animal models have demonstrated the importance of adequate nutrition for the neurodevelopmental processes that occur rapidly during pregnancy and infancy, such as neuron proliferation and myelination. However, several factors influence whether nutrient deficiencies during this period cause permanent cognitive deficits in human populations, including the child's interaction with the environment, the timing and degree of nutrient deficiency, and the possibility of recovery. These factors should be taken into account in the design and interpretation of future research. Certain types of nutritional deficiency clearly impair brain development, including severe acute malnutrition, chronic undernutrition, iron deficiency, and iodine deficiency. While strategies such as salt iodization and micronutrient powders have been shown to improve these conditions, direct evidence of their impact on brain development is scarce. Other strategies also require further research, including supplementation with iron and other micronutrients, essential fatty acids, and fortified food supplements during pregnancy and infancy. © 2014 International Life Sciences Institute.

  18. Inflammatory bowel diseases: principles of nutritional therapy

    Directory of Open Access Journals (Sweden)

    Campos Fábio Guilherme

    2002-01-01

    Full Text Available Inflammatory Bowel Diseases - ulcerative colitis and Crohn's disease- are chronic gastrointestinal inflammatory diseases of unknown etiology. Decreased oral intake, malabsorption, accelerated nutrient losses, increased requirements, and drug-nutrient interactions cause nutritional and functional deficiencies that require proper correction by nutritional therapy. The goals of the different forms of nutritional therapy are to correct nutritional disturbances and to modulate inflammatory response, thus influencing disease activity. Total parenteral nutrition has been used to correct and to prevent nutritional disturbances and to promote bowel rest during active disease, mainly in cases of digestive fistulae with high output. Its use should be reserved for patients who cannot tolerate enteral nutrition. Enteral nutrition is effective in inducing clinical remission in adults and promoting growth in children. Due to its low complication rate and lower costs, enteral nutrition should be preferred over total parenteral nutrition whenever possible. Both present equal effectiveness in primary therapy for remission of active Crohn's disease. Nutritional intervention may improve outcome in certain individuals; however, because of the costs and complications of such therapy, careful selection is warranted, especially in patients presumed to need total parenteral nutrition. Recent research has focused on the use of nutrients as primary treatment agents. Immunonutrition is an important therapeutic alternative in the management of inflammatory bowel diseases, modulating the inflammation and changing the eicosanoid synthesis profile. However, beneficial reported effects have yet to be translated into the clinical practice. The real efficacy of these and other nutrients (glutamine, short-chain fatty acids, antioxidants still need further evaluation through prospective and randomized trials.

    The past seven decades have seen remarkable shifts in the nutritional scenario in India. Even up to the 1950s severe forms of malnutrition such as kwashiorkar and pellagra were endemic. As nutritionists were finding home-grown and common-sense solutions for these widespread problems, the population was burgeoning and food was scarce. The threat of widespread household food insecurity and chronic undernutrition was very real. Then came the Green Revolution. Shortages of food grains disappeared within less than a decade and India became self-sufficient in food grain production. But more insidious problems arising from this revolution were looming, and cropping patterns giving low priority to coarse grains and pulses, and monocropping led to depletion of soil nutrients and 'Green Revolution fatigue'. With improved household food security and better access to health care, clinical manifestations of severe malnutrition virtually disappeared. But the decline in chronic undernutrition and "hidden hunger" from micronutrient deficiencies was slow. On the cusp of the new century, an added factor appeared on the nutritional scene in India. With steady urban migration, upward mobility out of poverty, and an increasingly sedentary lifestyle because of improvements in technology and transport, obesity rates began to increase, resulting in a dual burden. Measured in terms of its performance in meeting its Millennium Development Goals, India has fallen short. Despite its continuing high levels of poverty and illiteracy, India has a huge demographic potential in the form of a young population. This advantage must be leveraged by investing in nutrition education, household access to nutritious diets, sanitary environment and a health-promoting lifestyle. This requires co-operation from all the stakeholders, including governments, non government organizations, scientists and the people at large.

    Full Text Available In order to diagnose the nutritional status and to provide a personalized treatment in PKU patients, an evaluation of nutritional status should be conducted. Several components are involved in the nutritional assessment; among the parameters there are anthropometric evaluation: weight, height, head circumference; biochemical: proteins, amino acids, vitamins, inorganic nutrients, essential fatty acids; clinical: deficiencies in hair, skin, oral cavity , eyes, etc.; dietary assessment: quantification of energy intake, macronutrients and micronutrients through several tools such as the 24-hour recall; finally it must be taken into account the interaction of nutrients such as carnitine, fatty acids, vitamin B complex, among others, with drugs, which are often anticonvulsants, in order to plan the diet and prevent a future nutritional deficiency. It is important to perform the nutritional status assessment frequently in patients with PKU because the dietary management is essential to prevent neurological problems.

    Full Text Available The nutritional status of an individual is usually a result of multiple factors that interact with each other at different levels. Recognizing the role of diet at the onset of many diseases and assessing the nutritional status of an individual, family and community are important for public health. The nutritional assessment is done to obtain information about the prevalence and geographic distribution of nutritional disorders within a community or a specified population group. It can also be used to identify high-risk groups and to assess the role of different epidemiological factors in nutritional deficiency. Assessment of the nutritional status aids assessing the prevalence of nutritional disorders, planning corrective measures, and evaluating the effectiveness of the implemented strategies simultaneously.

    Iodine is essential for thyroid hormone synthesis, and iodine deficiency may result in thyroid disorders including goiter and hypothyroidism. Patients on long-term enteral nutrition (EN) or parenteral nutrition (PN) may be at risk for micronutrient deficiencies. The recommended daily allowance for iodine intake is 150 μg for nonpregnant adults. However, there is no current consensus among scientific societies regarding the quantity of iodine to be added in adult EN and PN formulations. The objective of this study was to determine the iodine content of U.S. adult enteral and parenteral nutrition solutions. This study also aimed to determine whether adult patients in the United States who are receiving long-term artificial nutrition may be at risk for iodine deficiency. Ten enteral nutrition solutions and 4 parenteral nutrition solutions were evaluated. The iodine contents of these solutions were measured spectrophotometrically and compared to the labeled contents. Measured and labeled EN iodine contents were similar (range 131-176 μg/L and 106-160 μg/L, respectively). In contrast, PN formulas were found to contain small, unlabeled amounts of iodine, averaging 27 μg/L. Typical fluid requirements are 30 to 40 mL/kg/day for adults receiving either total EN (TEN) or total PN (TPN). Adults on long-term TEN likely consume enough servings to meet their daily iodine requirements. However, patients on long-term TPN would require on average 5.6 L PN/day to meet the recommended daily allowance of iodine. This volume of PN is far in excess of typical consumption. Thus, U.S. patients requiring long-term TPN may be at risk for iodine deficiency. EN = enteral nutrition; PN = parenteral nutrition; TEN = total enteral nutrition; TPN = total parenteral nutrition; UIC = urinary iodine concentration.

  16. Nutritional aspects related to endometriosis

    Directory of Open Access Journals (Sweden)

    Gabriela Halpern

    2015-12-01

    Full Text Available SUMMARY This literature review analyzed the evidence on nutritional aspects related to the pathogenesis and progression of endometriosis. Diets deficient in nutrients result in changes in lipid metabolism, oxidative stress and promote epigenetic abnormalities, that may be involved in the genesis and progression of the disease. Foods rich in omega 3 with anti-inflammatory effects, supplementation with Nacetylcysteine, vitamin D and resveratrol, in addition to the increased consumption of fruits, vegetables (preferably organic and whole grains exert a protective effect, reducing the risk of development and possible regression of disease. Dietary re-education seems to be a promising tool in the prevention and treatment of endometriosis.

  17. Magnesium deficiency and increased inflammation: current perspectives

    Directory of Open Access Journals (Sweden)

    Nielsen FH

    2018-01-01

    Full Text Available Forrest H Nielsen Research Nutritionist Consultant, Grand Forks, ND, USA Abstract: Animal studies have shown that magnesium deficiency induces an inflammatory response that results in leukocyte and macrophage activation, release of inflammatory cytokines and acute-phase proteins, and excessive production of free radicals. Animal and in vitro studies indicate that the primary mechanism through which magnesium deficiency has this effect is through increasing cellular Ca2+, which is the signal that results in the priming of cells to give the inflammatory response. Primary pro-inflammatory cytokines such as tumor necrosis factor-α and interleukin (IL-1; the messenger cytokine IL-6; cytokine responders E-selectin, intracellular adhesion molecule-1 and vascular cell adhesion molecule-1; and acute-phase reactants C-reactive protein and fibrinogen have been determined to associate magnesium deficiency with chronic low-grade inflammation (inflammatory stress. When magnesium dietary intake, supplementation, and/or serum concentration suggest/s the presence of magnesium deficiency, it often is associated with low-grade inflammation and/or with pathological conditions for which inflammatory stress is considered a risk factor. When magnesium intake, supplementation, and/or serum concentration suggest/s an adequate status, magnesium generally has not been found to significantly affect markers of chronic low-grade inflammation or chronic disease. The consistency of these findings can be modified by other nutritional and metabolic factors that affect inflammatory and oxidative stress. In spite of this, findings to date provide convincing evidence that magnesium deficiency is a significant contributor to chronic low-grade inflammation that is a risk factor for a variety of pathological conditions such as cardiovascular disease, hypertension, and diabetes. Because magnesium deficiency commonly occurs in countries where foods rich in magnesium are not consumed in

    Rosania, Rosa; Chiapponi, Costanza; Malfertheiner, Peter; Venerito, Marino

    2016-05-01

    Nutritional management of patients with gastric cancer (GC) represents a challenge. This review provides an overview of the present evidence on nutritional support in patients with GC undergoing surgery as well as in those with advanced disease. For patients undergoing surgery, the preoperative nutritional condition directly affects postoperative prognosis, overall survival and disease-specific survival. Perioperative nutritional support enriched with immune-stimulating nutrients reduces overall complications and hospital stay but not mortality after major elective gastrointestinal surgery. Early enteral nutrition after surgery improves early and long-term postoperative nutritional status and reduces the length of hospitalization as well. Vitamin B12 and iron deficiency are common metabolic sequelae after gastrectomy and warrant appropriate replacement. In malnourished patients with advanced GC, short-term home complementary parenteral nutrition improves the quality of life, nutritional status and functional status. Total home parenteral nutrition represents the only modality of caloric intake for patients with advanced GC who are unable to take oral or enteral nutrition. Early evaluations of nutritional status and nutritional support represent key aspects in the management of GC patients with both operable and advanced disease.

    2016-01-01

    Immigrant and refugee populations bring public health challenges to host nations. In the current global refugee crisis, children are the most vulnerable subpopulation. Diseases that were considered rare in the host nation may be highly prevalent among immigrant children. The prevalence of nutritional rickets is increasing in high-income countries, largely driven by an influx of immigrant populations. Nutritional rickets is a bone disease in early childhood resulting in bone pain, delayed motor development, and bending of the bones, caused by vitamin D deficiency and/or inadequate dietary calcium intake. The consequences of nutritional rickets include stunted growth, developmental delay, lifelong bone deformities, seizures, cardiomyopathy, and even death. Nutritional rickets is most commonly seen in children from the Middle East, Africa, and South Asia in high-income countries. Dark skin pigmentation, sun avoidance, covering the skin, and prolonged breast feeding without vitamin D supplementation, are important risk factors for vitamin D deficiency, and combined with a lack of dairy products in the diet, these deficiencies can result in insufficient calcium supply for bone mineralization. We recommend screening all immigrant and refugee children under 5 years of age from these ethnic groups for nutritional rickets, based on clinical features, and confirming the diagnosis with radiographs of the wrists and knees. Because nutritional rickets is entirely preventable, public health policies must address the need for universal vitamin D supplementation and adequate dietary calcium to protect children from this scourge. Vitamin D supplementation of all infants and children with 400 IU/d during the first year of life and dietary or supplemental intakes of at least 600 IU/d of vitamin D and 500 mg/d of calcium thereafter, will effectively prevent nutritional rickets. We call on national health authorities of host countries to implement health check lists and prevention

  1. Zinc Deficiency in Humans and its Amelioration

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Zinc (Zn deficiency in humans has recently received considerable attention. Global mortality in children under 5 years of age in 2004 due to Zn deficiency was estimated at 4,53,207 as against 6,66,771 for vitamin A deficiency; 20,854 for iron deficiency and 3,619 for iodine deficiency. In humans 2800-3000 proteins contain Zn prosthetic group and Zn is an integral component of zinc finger prints that regulate DNA transcription. Zinc is a Type-2 nutrient, which means that its concentration in blood does not decrease in proportion of the Zn deficiency. Adverse effects of Zn deficiency vary with age: low weight gain, diarrhoea, aneroxia and neurobehavioral disturbances are observed in infants, while skin changes and dwarfism are frequent in toddlers and adolescents. Common manifestations of Zn deficiency among elderly include hypogeusia, chronic non-healing ulcers and recurrent infections.Ameliorative measures of Zn deficiency in humans can be classified in two groups, namely, nutraceutical and biofortification of food grains. Nutraceutical interventions include pharmaceutical supplements, dietary supplements and dietary diversification, while biofortification of food grains can be achieved by genetic modification (GM of crops or by agronomic techniques that include soil or/and foliar fertilization of crops.The major disadvantage of nutraceutical approaches is that the major beneficiaries are urban people and the poor rural masses that need adequate Zn nutrition most are left out. Genetic biofortification of food grains requires large amounts of funds and a fairly long-period of time. Further, a large number of countries have not yet accepted genetically modified (GM foods. On the other hand agronomic biofortification of food grains yields immediate effects and rural and urban people are equally benefitted.

    Iron deficiency and anemia are changes often associated with obesity. Bariatric surgery is responsible for increasing the iron loss and reducing its absorption. The objective of this study was to evaluate anemia and iron deficiency before and after bariatric surgery and to relate them to possible predisposing factors. A retrospective study was conducted on obese patients submitted to open Roux-en-Y gastric bypass, in which clinical and laboratory data were obtained up to 48 months postoperatively. Patients were divided into groups according to the presence or absence of anemia and to the presence or absence of iron deficiency (even without anemia), and all data were compared between these groups. Preoperatively, 21.5% of patients had anemia and 20% had iron deficiency. The number of patients with anemia did not vary through the 4 years of the study, but ferritin levels significantly decreased with time (Panemia. Female gender was a variable associated with a greater incidence of iron deficiency. Anemia and iron deficiency are frequent in obese patients and must be treated before surgery. Medical and nutritional surveillance is important in the postoperative period of bariatric surgery. Management of each condition must be directed at correcting the 2 major sources of iron deficiency and anemia: food intolerance (mostly meat intolerance) and losses (frequently due to menstruation). These are the factors more related to iron deficient anemia. Copyright © 2014 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

  4. Iron deficiency anaemia in Sri Lanka

    International Nuclear Information System (INIS)

    Liyanage, K.D.C.E.

    1992-01-01

    The commonest cause of nutritional anaemia in the Sri Lankan population is iron deficiency. The diets of the population belonging to the lower socio-economic groups contain little food of animal origin. Thus, their diets are deficient in easily absorbable (haem) iron; and are also heavily cereal-based. Therefore interference in the absorption of dietary iron also occurs. Iron-deficiency anaemia is not restricted to the so-called ''vulnerable groups'' in Sri Lanka, however, their greater demands make the problem not only commoner but also more severe. Among pregnant and lactating women anaemia is often associated with folate deficiency. It must also be noted that the low availability of dietary iron is compounded in large population groups. Malaria, presently raging on an epidemic scale is also a major contributory factor to the incidence of anaemia. The purpose of this study was to examine the iron status of pre-school children and pregnant women; to establish normal levels of biochemical indices at different trimesters; to record the effect of iron supplementation during pregnancy; and to record the bioavailability of iron from weaning foods and common adult diets. 6 figs, 14 tabs

  6. Adult classical homocystinuria requiring parenteral nutrition: Pitfalls and management.

    2017-07-25

    Homocystinuria due to cystathionine beta synthase (CBS) deficiency presents with a wide clinical spectrum. Treatment by the enteral route aims at reducing homocysteine levels by using vitamin B6, possibly methionine-restricted diet, betaine and/or folate and vitamin B 12 supplementation. Currently no nutritional guidelines exist regarding parenteral nutrition (PN) under acute conditions. Exhaustive literature search was performed, in order to identify the relevant studies describing the pathogenesis and nutritional intervention of adult classical homocystinuria requiring PN. Description of an illustrative case of an adult female with CBS deficiency and intestinal perforation, who required total PN due to contraindication to enteral nutrition. Nutritional management of decompensated classical homocystinuria is complex and currently no recommendation exists regarding PN composition. Amino acid profile and monitoring of total homocysteine concentration are the main tools enabling a precise assessment of the severity of metabolic alterations. In case of contraindication to enteral nutrition, compounded PN will be required, as described in this paper, to ensure adequate low amounts of methionine and others essential amino acids and avoid potentially fatal toxic hypermethioninemia. By reviewing the literature and reporting successful nutritional management of a decompensated CBS deficiency using tailored PN with limited methionine intake and n-3 PUFA addition, we would like to underscore the fact that standard PN solutions are not adapted for CBS deficient critical ill patients: new solutions are required. High methionine levels (>800 μmol/L) being potentially neurotoxic, there is an urgent need to improve our knowledge of acute nutritional therapy.

    to obtain information on the mothers, and their hemoglobin levels were dosed using Hemocue, also registering the mothers' height and weight. Information on the newborns was obtained from the Birth Registries Information System. RESULTS: A total of 168 low-income, low-schooling level pregnant women were evaluated, 41.3% showing inadequate pre-gestational nutritional status, 25.7% being underweight and 17.4% overweight or obese. The majority of the pregnant women presented inadequate weight gain during pregnancy. The prevalence of total iron deficiency anemia was 21.4%, increasing with gestational age. The frequencies of low birth weight and insufficient birth weight were 8.9% and 28.6%, respectively. The anthropometrical variables (pre-gestational weight, height, pre-gestational Body Mass Index and total weight gain presented a statistically significant association with weight at birth. CONCLUSION: The mother's anthropometrical variables correlated with the weight at birth. No correlation was found between the nutritional iron status of the pregnant women and weight at birth.

    DEFF Research Database (Denmark)

    Schmidt, Sidsel Birkelund; Jensen, Poul Erik; Husted, Søren

    2016-01-01

    Manganese (Mn) is an essential plant micronutrient with an indispensable function as a catalyst in the oxygen-evolving complex (OEC) of photosystem II (PSII). Even so, Mn deficiency frequently occurs without visual leaf symptoms, thereby masking the distribution and dimension of the problem...... restricting crop productivity in many places of the world. Hence, timely alleviation of latent Mn deficiency is a challenge in promoting plant growth and quality. We describe here the key mechanisms of Mn deficiency in plants by focusing on the impact of Mn on PSII stability and functionality. We also address...... the mechanisms underlying the differential tolerance towards Mn deficiency observed among plant genotypes, which enable Mn-efficient plants to grow on marginal land with poor Mn availability....

  13. Is zinc deficiency a risk factor for atherosclerosis?

    Science.gov (United States)

    Beattie, John H; Kwun, In-Sook

    2004-02-01

    The development of atherosclerosis is influenced by genetic, lifestyle and nutritional risk factors. Zn and metallothionein deficiency can enhance oxidative-stress-related signalling processes in endothelial cells, and since changes in available plasma Zn may affect the Zn status of the endothelium, Zn deficiency could be a risk factor for IHD. Although the association of Zn with many proteins is essential for their function, three key signalling processes are highlighted as being principal targets for the effect of Zn deficiency: the activation of NF-kappaB, the activation of caspase enzymes and the signalling of NO. The need to develop a reliable indicator of Zn status is critical to any epidemiological approach for studying the relationship between Zn status and disease incidence. Studies using appropriate animal models and investigating how the plasma Zn pool influences endothelial intracellular labile Zn would be helpful in appreciating the importance of Zn deficiency in atherogenesis.

    To study the relationship between pica and iron-lack anaemia in a series of iron-deficiency patients in order to establish the pathogenesis of such relationship. Four-hundred and thirty-three patients were analysed. Pica was studied by introducing certain diet queries into the clinical history. All patients received oral iron and were periodically controlled with the usual clinico-haematological procedures. Pica was present in 23 patients (5.3%). Eight nourishing (namely, coffee grains, almonds, chocolate, ice, lettuce, carrots, sunflower seeds and bread) and 2 non-nourishing (clay and paper) substances were involved. A second episode of pica appeared in 9 cases upon relapsing of iron deficiency. Both anaemia and pica were cured by etiologic and substitutive therapy in all instances. No clear correlation was found with either socio-economic status or pathogenetic causes of iron deficiency and pica, and no haematological differences were seen between patients with pica and those without this alteration. (1) The pathogenesis of pica is unclear, although it appears unrelated to the degree of iron deficiency. (2) According to the findings in this series, pica seems a consequence of iron deficiency rather than its cause. (3) Adequate therapy can cure both conditions, although pica may reappear upon relapse of iron deficiency.

  16. Nutritional status and nutritional support before and after pancreatectomy for pancreatic cancer and chronic pancreatitis.

    Science.gov (United States)

    Karagianni, Vasiliki Th; Papalois, Apostolos E; Triantafillidis, John K

    2012-12-01

    Cachexia, malnutrition, significant weight loss, and reduction in food intake due to anorexia represent the most important pathophysiological consequences of pancreatic cancer. Pathophysiological consequences result also from pancreatectomy, the type and severity of which differ significantly and depend on the type of the operation performed. Nutritional intervention, either parenteral or enteral, needs to be seen as a method of support in pancreatic cancer patients aiming at the maintenance of the nutritional and functional status and the prevention or attenuation of cachexia. Oral nutrition could reduce complications while restoring quality of life. Enteral nutrition in the post-operative period could also reduce infective complications. The evidence for immune-enhanced feed in patients undergoing pancreaticoduodenectomy for pancreatic cancer is supported by the available clinical data. Nutritional support during the post-operative period on a cyclical basis is preferred because it is associated with low incidence of gastric stasis. Postoperative total parenteral nutrition is indicated only to those patients who are unable to be fed orally or enterally. Thus nutritional deficiency is a relatively widesoread and constant finding suggesting that we must optimise the nutritional status both before and after surgery.

  17. Benefits of nutritional intervention on nutritional status, quality of life and survival.

    Science.gov (United States)

    Van Eys, J

    1998-01-01

    Most cancers in children are acute diseases. Therefore, the incidence of malnutrition, in general, is not different from the incidence in the referral population. Some specific tumors, such as neuroblastoma and those resulting in the diencephalic syndrome, can be exceptions. By contrast, malnutrition is a frequent problem during modern intensive cancer treatment as the result of the associated anorexia, altered taste sensations and catabolic effects of drugs. In addition, there are psychogenic factors and metabolic consequences associated with the tumor itself. Nutritional support does improve the feeling of well-being and performance status, while maintaining or improving the immune competence, thereby potentially affecting survival by limiting infectious episodes. There is no convincing evidence to date that nutritional support has an antineoplastic effect per se, but deficiency of a specific nutrient might be beneficial because of a differential requirement between tumor and normal cells. Theoretically, nutritional support might enhance tumor growth but also susceptibility to chemotherapy. In either case, nutrition is a support modality that must be given with appropriate tumor-directed therapy if curative intent is the goal of treatment. Nutrition remains a consideration after therapy is completed. This generates different challenges. If further tumor-directed therapy is futile, the decision to continue nutritional support is difficult, but if the child is well, nutritional rehabilitation must be pursued. Finally, the cured child continues to benefit from dietary advice. Nutrition should be viewed for what it is: supplying the most basic need of children.

  14. White muscle disease in three selenium deficient beef and dairy calves in Argentina and Uruguay

    Directory of Open Access Journals (Sweden)

    Alejandro Martín Rodriguez

    2018-05-01

    Full Text Available ABSTRACT: White muscle disease (WMD, nutritional myodegeneration or enzootic muscular dystrophy, is a nutritional condition associated with selenium and/or vitamin E deficiency in ruminants. These elements are constituents of the major body antioxidant systems. Depletion of selenium results in oxidative damage to cardiac and skeletal muscle cells, resulting in myodegeneration and myonecrosis, typical lesions of WMD. Selenium deficiency is common in South America, but WMD is underreported. This research describes clinical, biochemical and pathological findings in two episodes of WMD associated with selenium deficiency in beef and dairy calves in Argentina and Uruguay with concurrent copper deficiency in one of them, which resulted in spontaneous calf mortality. Further studies are necessary to estimate the true incidence and economic impact of clinical and subclinical mineral deficiencies in livestock production systems in the southern cone of South America.

    2012-01-01

    Full Text Available Background. The aim of this study was to investigate patient outcomes and nutritional deficiencies following sleeve gastrectomy (SG during a follow-up of two years. Methods. Over a period of 56 months, all consecutive patients who underwent SG were documented in this prospective, single-center, observational study. The study endpoints included operative time, complication rates, nutritional deficiencies and percentage of excess weight loss (%EWL. Results. From September 26, 2005 to May 28, 2009, 82 patients (female : male = 48 : 34 with a mean age of 43.3 years (range: 22–64 and a preoperative BMI of 52.5 kg/m² (range: 36.8–77.0 underwent SG. Major complications were observed in 9.8% of the patients, with 1 death. During follow up 51.2% of patients were supplemented with iron, 36.6% with zinc, 37.8% with calcium, 26.8% with vitamin D, 46.3% with vitamin B12 and 41.5% with folic acid. %EWL was 54.3, 65.3 and 62.6% after 6, 12 and 24 months. Conclusion. SG as a single step procedure is an effective bariatric intervention. Nutritional deficiencies after SG can be detected by routine nutritional screening. Our results show that Vitamin B12 supplementation should suggest routinely after SG.

    Directory of Open Access Journals (Sweden)

    M Noori Shadkam

    2009-07-01

    Full Text Available Introduction: It is generally assumed that 50% of the cases of anemia are due to iron deficiency. The most severe consequence of iron depletion is iron deficiency anemia (IDA, and it is still considered the most common nutrition deficiency worldwide. The main risk factors for IDA include: inadequate iron intake, impaired absorption or transport, physiologic losses associated with chronological or reproductive age, or acute or chronic blood loss, parasite infections such as hookworms, acute and chronic infections, including malaria, cancer, tuberculosis, HIV and other micronutrient deficiencies, including vitamins A and B12, folate, riboflavin, and copper deficiency. Methods: This work as a cross-sectional study was done in 2007-2008 in Yazd. Two hundred girls who participated in the study were selected randomly from eight girl high schools. Five ml venous blood was collected for determination of serum ferritin and cell blood count (CBC. Serum ferritin was determined by using ECLIA method and CBC by cell counter SYSMEX KX21N. Iron deficiency was defined as having serum ferritin values below 12 μ/l. Anemia was defined as having Hemoglobin levels below12 g/dl. Iron-deficiency anemia was considered to be the combination of both. Results: The3 mean ageyears and body mass index (kg/m2 were 15.19±0.7years and 21.5±4.2, respectively. Distribution in the 14, 15 and 16 years and more age groups were 13, 58.5 and 28.5 percent, respectively. Mean of Hemoglobin(g/dl, Hematocrit(%, MCV (fl, MCH (pg, MCHC (g/dl and ferritin(μ/l were 12.8±0.9, 38.9±3.0, 80.7±4.3, 26.6±1.8, 33.2±3.6 and 23±18.2, respectively. Of the total, 13.5% were anemic, 68% of which had Iron Deficiency Anemia (9.3% of the total. Iron deficiency was present in 34.7% of the population under study. Conclusion: According to world health organization criteria, anemia is a mild public health problem in this region, but iron deficiency is a significant problem and suitable measures for

  18. Nutrition support of the pediatric patient with AIDS.

    Bentler, M; Stanish, M

    1987-04-01

    Maintaining optimal nutrition in the pediatric patient with Acquired Immune Deficiency Syndrome (AIDS) is challenging, but it may be one of the most effective therapies. Patients experience numerous complications that compromise nutritional status. Infection, fever, diarrhea, feeding problems, and decreased intake all contribute to malnutrition, which in turn predisposes the patient even more to infection and malabsorption. Nutrition assessment should be done routinely so that new problems may be identified and treated. High-calorie, high-protein feedings, vitamin supplementation, and, when necessary, gavage feedings or parenteral nutrition are recommended to improve nutritional status and prevent further deficits. Maintaining optimal nutrition in the pediatric patient with Acquired Immune Deficiency Syndrome (AIDS) poses a significant challenge to the health care team. Patients may experience numerous complications that compromise nutritional status. The patient is at high risk for opportunistic infections, especially of the lungs, central nervous system, gastrointestinal (GI) tract, and skin. Such infections are common causes of morbidity and mortality. Impaired nutritional status may further impair the patient's immunocompetence. A study by Kotler and Gaety demonstrated severe progressive malnutrition in adult AIDS patients, with the lowest measures of lean body mass occurring in those patients close to death at the time of the study. While no studies of children with AIDS have been done to date, we have subjectively observed feeding problems, weight loss, and malnutrition in most of the patients we have seen.

    Evidence pertaining to the role of dietary factors in carcinogenesis comes from both epidemiological studies and laboratory experiments. In 1982, the Committee on Diet, Nutrition, and Cancer of the National Research Council conducted a comprehensive evaluation of this evidence. That assessment as well as recent epidemiological and laboratory investigations suggest that a high fat diet is associated with increased susceptibility to cancer of different sites, particularly the breast and colon, and to a lesser extent, the prostate. Current data permit no definitive conclusions about other dietary macroconstituents including cholesterol, total caloric intake, protein, carbohydrates and total dietary fiber. Specific components of fiber, however, may have a protective effect against colon cancer. In epidemiological studies, frequent consumption of certain fruits and vegetables, especially citrus fruits and carotene-rich and cruciferous vegetables, is associated with a lower incidence of cancers at various sites. The specific components responsible for these effects are not clearly identified, although the epidemiological evidence appears to be most consistent for a protective effect of carotene on lung cancer and less so for vitamins A and C and various cancer sites. The laboratory evidence is most consistent for vitamin A deficiency and enhanced tumorigenesis, and for the ability of various nonnutritive components in cruciferous vegetables to block in-vivo carcinogenesis. The data for minerals and carcinogenesis are extremely limited, although preliminary evidence from both epidemiological and laboratory studies suggests that selenium may protect against overall cancer risk. 402 references.

    There is a growing body of evidence that nutritional habits may have a significant effect on both male and female fertility. Maintenance of normal body mass may be effective in the prevention of infertility resulting from ovulatory disorders. Underweight and, to a larger degree, overweight and/or obesity, are related to the enhanced risk of infertility. Insulin resistance is an important pathogenic mechanism that may impair ovulation. Adequate intake of monounsaturated fatty acids, derived mainly from vegetable fats, as well as avoidance of trans isomers of unsaturated fatty acids which are present in industrially produced cakes and sweets, crisps, fast-foods, powdered soups and hard margarines, may be effective in the prevention of infertility in females. Choice of plant rather than animal sources of proteins, decrease in glycemic load of the diet, use of dietary supplements containing iron and folic acid, could also be beneficial. Avoidance of vitamin B12 deficiency and its supplementation seem to be important in the prevention of early miscarriages. Sufficient intake of antioxidants also promotes female reproductive functions. Free radical processes play an important role in the development of male factor infertility. It was shown that proper intake or supplementation with antioxidants may be effective in its prevention and treatment. Such nutrients as zinc, selenium and folic acid act beneficially on sperm quality. A well-balanced diet seems to play an important role in the prevention of infertility in both sexes.

    Full Text Available Aims and Background: Iron deficiency is one of the most common nutritional disorders worldwide and blood donation may cause iron depletion. Limited studies with large sample size have been done on male donors. The aim of this study is to determine the prevalence of iron deficiency and iron deficiency anemia among male donors in the Kurdistan Organization of Blood Transfusion in Iran. Materials and Methods: This was a cross-sectional study. Sample size was 1184 blood donors selected by systematic random sampling. Hemoglobin, serum iron, serum ferritin, total iron banding capacity (TIBC and transferin saturation were measured in donors. Iron depletion, lack of iron stores, iron deficiency, iron deficiency anemia and anemia were evaluated among them. Data was analyzed with SPSS software and X΂, one-way ANOVA, and LSD test. Results: Iron deficiency, anemia, iron deficiency anemia, iron depletion and lack of iron resources were seen in 2.3, 4.08, 2.14, 22.76 and 4.66 percent respectively. There was a significant relationship of iron deficiency and iron deficiency anemia with instances of donation and interval from last donation (P < 0.05. A significant relationship was seen between iron deficiency and iron deficiency anemia among blood donors with more than ten times blood donation (P < 0.05. Conclusions: This study showed regular male donors require especial attention. Therefore, serum ferritin is recommended as a more adequate index to use for iron deficiency screening and planning purposes for iron supplementation among them.

  4. Nutrition transition and food sustainability.

    The aim of the present paper is to review nutrition transition (NT) ongoing in low and middle income countries and the associated dietary changes. NT is accompanied by demographic and epidemiological transition associated with economic development and urbanisation. In these countries, while the problems of hunger and undernourishment persist, there is an escalation of diet-related non-communicable diseases; making them face both problems of malnutrition, under and overnutrition. Indeed, in addition to protein energy malnutrition underweight and micronutrient deficiencies affect a high proportion of children and women. Conversely, changes in dietary habits and physical activity patterns have led to emergence of chronic diseases such as obesity, diabetes, hypertension, stroke, hyperlipidaemia, CHD and cancer. One possible explanation of weight gain and its associated health consequences is the trend of the consumption of already prepared meals and the restaurants that are in continuous development leading to high consumption of foods rich in sugar and fat. The health problems associated with NT have not spared populations in the Mediterranean area where the type of diet is reported to be healthy and to protect against cardiovascular risks. This is seen in North Africa that belongs also to the Mediterranean basin, where the nutritional situation raises the problem of traditional foods sustainability. Accurate nutritional policy and education are needed to redress the effects of malnutrition related to NT on health.

    Contemporary elite soccer features increased physical demands during match-play, as well as a larger number of matches per season. Now more than ever, aspects related to performance optimization are highly regarded by both players and soccer coaches. Here, nutrition takes a special role as most elite teams try to provide an adequate diet to guarantee maximum performance while ensuring a faster recovery from matches and training exertions. It is currently known that manipulation and periodization of macronutrients, as well as sound hydration practices, have the potential to interfere with training adaptation and recovery. A careful monitoring of micronutrient status is also relevant to prevent undue fatigue and immune impairment secondary to a deficiency status. Furthermore, the sensible use of evidence-based dietary supplements may also play a role in soccer performance optimization. In this sense, several nutritional recommendations have been issued. This detailed and comprehensive review addresses the most relevant and up-to-date nutritional recommendations for elite soccer players, covering from macro and micronutrients to hydration and selected supplements in different contexts (daily requirements, pre, peri and post training/match and competition).

    2012-01-01

    Full Text Available Nutritional deficiencies are preventable etiological and epigenetic factors causing congenital abnormalities, first cause of infant mortality. Folate deficiency has a well-established teratogenic effect, leading to an increasing risk of neural tube defects. This paper highlights the most recent medical literature about folate deficiency, be it maternal or paternal. It then focuses on associated deficiencies as nutritional deficiencies are multiple and interrelated. Observational and interventional studies have all been consistent with a 50–70% protective effect of adequate women consumption of folates on neural tube defects. Since strategies to modify women’s dietary habits and vitamin use have achieved little progress, scientific as well as political effort is mandatory in order to implement global preventive public health strategies aimed at improving the alimentation of women in reproductive age, especially folic acid supplementation. Even with the recent breakthrough of fetal surgery for myelomeningocele, the emphasis should still be on prevention as the best practice rather than treatment of neural tube defects.

    Being home to 31% of the world's children who are stunted and 42% of those who are underweight, and with many children and adults affected by micronutrient deficiencies, India is facing huge challenges in the field of nutrition. Even though the Indian Government is investing vast amounts of money into programs that aim to enhance food security, health and nutrition (the Integrated Child Development Services program alone costs 3 billion USD per year), overall impact has been rather disappointing. However, there are some bright spots on the horizon. The recent District Level Health Surveys (DLHS-4) do show significant progress, ie a reduction in stunting of around 15% over the past 6 years in a few states for which preliminary results are available. The reasons for this reduction are not unambiguous and appear to include state government commitment, focus on the 'window of opportunity', improved status and education of women, a lowered fertility rate, and combinations of nutrition- specific and nutrition-sensitive interventions. Apart from the government many other agencies play a role in driving improvements in nutrition. Since 2006 the Global Alliance for Improved Nutrition (GAIN) has worked with a range of partners to improve access to nutritious foods for large parts of the population, through public and private delivery channels. This supplement presents a selection of these activities, ranging from a capacityassessment of frontline workers in the ICDS system, large scale staple food fortification, salt iodization, fortification of mid-day meals for school children and decentralized complementary food production.

    2014-11-01

    Full Text Available Ornithine transcarbamylase deficiency (OTCD is the most common type urea cycle enzyme deficiencies. This syndrome results from a deficiency of the mitochondrial enzyme ornithine transcarbamylase, which catalyzes the conversion of ornithine and carbamoyl phosphate to citrullin. Our case was a 28-year-old female diagnosed with OTCD following neurocognitive deficit during her first pregnancy. Although hyperammonemia was suspected as the cause of the patient's mental changes, there was no evidence of chronic liver disease. Plasma amino acid and urine organic acid analysis revealed OTCD. After combined modality treatment with arginine, sodium benzoate and hemodialysis, the patient's plasma ammonia level stabilized and her mental status returned to normal. At last she recovered without any damage left.

    Neurological diseases are frequently associated with swallowing disorders and malnutrition. Moreover, patients with neurological diseases are at increased risk of micronutrient deficiency and dehydration. On the other hand, nutritional factors may be involved in the pathogenesis of neurological diseases. Multiple causes for the development of malnutrition in patients with neurological diseases are known including oropharyngeal dysphagia, impaired consciousness, perception deficits, cognitive dysfunction, and increased needs. The present evidence- and consensus-based guideline addresses clinical questions on best medical nutrition therapy in patients with neurological diseases. Among them, management of oropharyngeal dysphagia plays a pivotal role. The guideline has been written by a multidisciplinary team and offers 88 recommendations for use in clinical practice for amyotrophic lateral sclerosis, Parkinson's disease, stroke and multiple sclerosis.

    Full Text Available During the recent years, there has been a surge of interest in the nutritional metabolic role of the "trace" mineral elements. Part of this interest is due to improved case in the quantitative analyses of these elements by the introduction of atomic absorption spectrophotometry. However, it has been the studies on zinc, in particular, that have fueled much of this interest when it was discovered that naturally-occurring zinc-deficiency could happen in man. It was reported that a syndrome consisting of dwarfism, iron-deficiency, anemia hepato-splenomegaly occurs in poor viIlages in Egypt and Iran. This syndrome was accompanied by low plasma and hair zinc levels, and decreased urinary excretion of zinc. Prior to this report, it has been tacitly assumed that since many of the "trace" elements occur in fairly abundant quantities in food, and because they are present in very small quantities in the tissues of man, dietary deficiency of the trace minerals was unlikely to occur in man. It has become obvious that difficulty in absorption or poor availability of the trace elements from the diet may prove to be an important etiologic mechanism in the causation of deficiencies of these elements. In the case of zinc, a study in the United States reported cases of children with low hair zinc concentration and with low taste acuity (hypogeusia. The condition responded to treatment with zinc supplementation. It was also reported that zinc-deficiency is secondary to intestinal malabsorption. The possibility that zinc-deficiency might accompany protein-calorie malnutritions had been suggested by some investigators who found low plasma zinc levels in children with kwashiorkor. Since protein-calorie malnutrition is a world-wide problem and is particularly common in developing countries, it appears important that in the nutrition research programs of such countries.

    Chronic kidney disease (CKD) is a common disease of civilization where nutrition is part of the treatment. Diet therapy is difficult as it is necessary to control the intake of: energy, protein and minerals – Na, K, Ca and P in the daily food rations (DFR). The aim of the study was to assess the nutritional status and diets of haemodialysis (HD) patients. The study involved 141 haemodialysis patients, at the average age of 65.9. The patients were divided into groups taking into consideration their sex and diagnosis for diabetes. The information on the diets were collected using a 7-day dietary recall. In the DFRs the amount of energy and 22 nutrients were calculated. Obtained results were compared with requirements for HD patients. Appropriate nutritional status (measured with BMI) was reported for majority of women (70.6%) and almost half of men, however, excessive weight was recognized in every third female patient and more than half male patients, and type I obesity was noted in 7.8% of men. The analysis of the results showed that diets of all examined patients were deficient in energy and protein (except women with diabetes), whereas the consumption of fat was appropriate in both groups of women. The recommendations with respect to the amount of cholesterol were met but dietary fibre was too low. Intake of vitamins B1, D, C, folates and Ca and Mg was lower and intake of vitamin B12 was higher than recommended. Assessment of the coverage of the demand on nutrients in HD patients should not be based on the analysis of their nutritional status (BMI) only but also on the analysis of diets, especially in case of diabetes.

    This review describes the pathogenesis, clinical presentation and biochemical perturbations found in privational (nutritional) rickets and pseudo-vitamin D deficiency rickets (PDDR), an autosomal recessive condition with loss of function mutations in CYP27B1. It may seem strange to combine a discussion on privational rickets and PDDR as a single topic, but privational rickets and PDDR present with similar clinical signs and symptoms and with similar perturbations in bone and mineral metabolism. Of interest is the characteristic lack of features of rickets at birth in infants with PDDR, a finding which has also been reported in infants born to vitamin D-deficient mothers. This highlights the independence of the fetus and neonate from the need for vitamin D to maintain calcium homeostasis during this period. The variable roles of vitamin D deficiency and dietary calcium deficiency in the pathogenesis of privational rickets are discussed and the associated alterations in vitamin D metabolism highlighted. Although PDDR is a rare autosomal recessive disorder, results of long-term follow-up are now available on the effect of treatment with calcitriol, and these are discussed. Areas of uncertainty, such as should affected mothers breastfeed their infants, are emphasized. PMID:24818008

We report a case of a 39-year-old woman with a body mass index (BMI of 29 kg/m2 who developed visual loss and bilateral optic nerve head swelling after a short, self-limited gastrointestinal illness. She was disoriented and inattentive and had absent ankle jerk reflexes, diminished sensation in both legs below the knees, and marked truncal ataxia. Magnetic resonance imaging (MRI showed increased T2-signal in the medial thalami and mammillary bodies. The serum thiamine level was 8 nmol/L (normal 8–30. The diagnosis of thiamine deficiency was made, and the patient’s vision and neurologic symptoms improved significantly with intramuscular thiamine treatment. Thiamine deficiency can occur in the absence of an obvious predisposing factor such as alcoholism or low body weight. The clinician must be aware of the factors that govern vitamin availability and maintain a high index of suspicion to make the diagnosis in such cases.Keywords: optic neuropathy, nutritional deficiency

    2013-01-01

    Malnutrition, marked by variant nutrient deficiencies, is considered a leading cause of stunted growth worldwide. In developing countries, malnutrition is caused mainly by food shortage and infectious diseases. Malnutrition may also be found in the developed world, where it is due mostly to prematurity, chronic diseases, and anorexia nervosa. In most cases, when food consumption is corrected, spontaneous catch-up (CU) growth occurs. However, CU growth is not always complete, leading to growth deficits. Therefore, it is important to understand the mechanisms that govern this process. Using a rat model of food restriction followed by refeeding, we established a nutrition-induced CU growth model. Levels of leptin and insulin-like growth factor-1 were found to significantly decrease when food was restricted and to increase already 1 day after refeeding. Gene expression analysis of the growth plate revealed that food restriction specifically affects transcription factors such as the hypoxia inducible factor-1 and its downstream targets on the one hand, and global gene expression, indicating epigenetic regulation, on the other. Food restriction also reduced the level of several microRNAs, including the chondrocyte-specific miR-140, which led to an increase in its target, SIRT1, a class III histone deacetylase. These findings may explain the global changes in gene expression observed under nutritional manipulation. We suggest that multiple levels of regulation, including transcription factors, epigenetic mechanisms, and microRNAs respond to nutritional cues and offer a possible explanation for some of the effects of food restriction on epiphyseal growth plate growth. The means whereby these components sense changes in nutritional status are still unknown. Deciphering the role of epigenetic regulation in growth may pave the way for the development of new treatments for children with growth disorders. Copyright © 2013 S. Karger AG, Basel.

    2015-12-01

    Arginase-1 (ARG1) deficiency is a rare autosomal recessive disorder that affects the liver-based urea cycle, leading to impaired ureagenesis. This genetic disorder is caused by 40+ mutations found fairly uniformly spread throughout the ARG1 gene, resulting in partial or complete loss of enzyme function, which catalyzes the hydrolysis of arginine to ornithine and urea. ARG1-deficient patients exhibit hyperargininemia with spastic paraparesis, progressive neurological and intellectual impairment, persistent growth retardation, and infrequent episodes of hyperammonemia, a clinical pattern that differs strikingly from other urea cycle disorders. This review briefly highlights the current understanding of the etiology and pathophysiology of ARG1 deficiency derived from clinical case reports and therapeutic strategies stretching over several decades and reports on several exciting new developments regarding the pathophysiology of the disorder using ARG1 global and inducible knockout mouse models. Gene transfer studies in these mice are revealing potential therapeutic options that can be exploited in the future. However, caution is advised in extrapolating results since the lethal disease phenotype in mice is much more severe than in humans indicating that the mouse models may not precisely recapitulate human disease etiology. Finally, some of the functions and implications of ARG1 in non-urea cycle activities are considered. Lingering questions and future areas to be addressed relating to the clinical manifestations of ARG1 deficiency in liver and brain are also presented. Hopefully, this review will spark invigorated research efforts that lead to treatments with better clinical outcomes.

    Isolated sulfite oxidase (SO) deficiency is an autosomal recessively inherited inborn error of sulfur metabolism. In this report of a ninth patient the clinical history, laboratory results, neuropathological findings and a mutation in the sulfite oxidase gene are described. The data from this patient and previously published patients with isolated sulfite oxidase deficiency and molybdenum cofactor deficiency are summarized to characterize this rare disorder. The patient presented neonatally with intractable seizures and did not progress developmentally beyond the neonatal stage. Dislocated lenses were apparent at 2 months. There was increased urine excretion of sulfite and S-sulfocysteine and a decreased concentration of plasma cystine. A lactic acidemia was present for 6 months. Liver sulfite oxidase activity was not detectable but xanthine dehydrogenase activity was normal. The boy died of respiratory failure at 32 months. Neuropathological findings of cortical necrosis and extensive cavitating leukoencephalopathy were reminiscent of those seen in severe perinatal asphyxia suggesting an etiology of energy deficiency. A point mutation that resulted in a truncated protein missing the molybdenum-binding site has been identified.

    2007-10-01

    Full Text Available Pancreaticoduodenectomy (PD is the standard operation for periampullary lesions. Most reports have focused on the clinical outcome, complications and tumor recurrence after PD. Few studies have focused on the nutritional sequelae that result from the extended resection of the upper gastrointestinal tract and disruption of the normal physiologic process of digestion. Zinc is absorbed mainly in the duodenum and proximal jejunum, which are removed during PD. Herein, we report two patients who experienced zinc deficiency with acrodermatitis enteropathica-like eruption, alopecia, glossitis and nail dystrophy after PD. The lesions improved dramatically after supplementation with zinc sulfate, pancreatic enzyme and diet instructions. No symptoms related to zinc deficiency were noted on follow-up after nutritional instructions had been given to the patients.

    Maternal nutritional deficiency significantly perturbs the offspring's physiology predisposing them to metabolic diseases during adulthood. Vitamin B12 and folate are two such micronutrients, whose deficiency leads to elevated homocysteine levels. We earlier generated B12 and/or folate deficient rat models and using high-throughput proteomic approach, showed that maternal vitamin B12 deficiency modulates carbohydrate and lipid metabolism in the liver of pups through regulation of PPAR signaling pathway. In this study, using similar approach, we identified 26 differentially expressed proteins in the kidney of pups born to mothers fed with vitamin B12 deficient diet while only four proteins were identified in the folate deficient group. Importantly, proteins like calreticulin, cofilin 1 and nucleoside diphosphate kinase B that are involved in the functioning of the kidney were upregulated in B12 deficient group. Our results hint towards a larger effect of vitamin B12 deficiency compared to that of folate presumably due to greater elevation of homocysteine in vitamin B12 deficient group. In view of widespread vitamin B12 and folate deficiency and its association with several diseases like anemia, cardiovascular and renal diseases, our results may have large implications for kidney diseases in populations deficient in vitamin B12 especially in vegetarians and the elderly people.This article is part of a Special Issue entitled: Proteomics in India.

  12. Assessing nutritional diversity of cropping systems in African villages.

    Directory of Open Access Journals (Sweden)

    Roseline Remans

    Full Text Available BACKGROUND: In Sub-Saharan Africa, 40% of children under five years in age are chronically undernourished. As new investments and attention galvanize action on African agriculture to reduce hunger, there is an urgent need for metrics that monitor agricultural progress beyond calories produced per capita and address nutritional diversity essential for human health. In this study we demonstrate how an ecological tool, functional diversity (FD, has potential to address this need and provide new insights on nutritional diversity of cropping systems in rural Africa. METHODS AND FINDINGS: Data on edible plant species diversity, food security and diet diversity were collected for 170 farms in three rural settings in Sub-Saharan Africa. Nutritional FD metrics were calculated based on farm species composition and species nutritional composition. Iron and vitamin A deficiency were determined from blood samples of 90 adult women. Nutritional FD metrics summarized the diversity of nutrients provided by the farm and showed variability between farms and villages. Regression of nutritional FD against species richness and expected FD enabled identification of key species that add nutrient diversity to the system and assessed the degree of redundancy for nutrient traits. Nutritional FD analysis demonstrated that depending on the original composition of species on farm or village, adding or removing individual species can have radically different outcomes for nutritional diversity. While correlations between nutritional FD, food and nutrition indicators were not significant at household level, associations between these variables were observed at village level. CONCLUSION: This study provides novel metrics to address nutritional diversity in farming systems and examples of how these metrics can help guide agricultural interventions towards adequate nutrient diversity. New hypotheses on the link between agro-diversity, food security and human nutrition are

  13. Characterization of the effects of macronutrient deficiencies in mangabeira seedlings

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Knowledge of the mineral nutrition requirements of mangabeira (Hancornia speciosa Gomes is relatively scarce and rudimentary because there is a lack of consistent data concerning its nutritional demands at different developmental stages. The aim of this research was to characterize the visual symptoms of macronutrient deficiencies and to evaluate the effects of these deficiencies on the growth, the production of dry matter, and the leaf content of mangabeira. To achieve this goal, a greenhouse experiment was conducted at the Goiano Federal Institute (Instituto Federal Goiano in Rio Verde - GO, from January to June 2011 in which mangabeira plants were arranged in a random block design and grown in nutrient solutions. This experiment was replicated four times. The plants were treated with either a complete nutrient solution or a nutrient solution from which the individual macronutrient of interest (nitrogen (N, phosphorous (P, potassium (K, magnesium (Mg, calcium (Ca, or sulfur (S had been omitted. The omission of a macronutrient from the nutrient solution resulted in morphological alterations that were characteristic symptoms of the particular nutritional deficiency and caused decreases in growth and dry matter mass production. The accumulation of macronutrients displayed the following order in mangabeira leaves: N>K>Ca>P>S>Mg.

    Early child nutritional deficiencies are prevalent in low- and middle-countries with consequences linked not only to poor survival and growth, but also to poor development outcomes. Children in disadvantaged communities face multiple risks for nutritional deficiencies, yet some children may be less susceptible or may recover more quickly from malnutrition. A greater understanding is needed about factors which moderate the effects of nutrition-related risks and foster resilience to protect against or ameliorate poor development outcomes. A literature review was undertaken from August to December 2011 and updated in August 2012. Key word searches using terms Nutrition, Malnutrition, Child Development, Responsive Care, Stimulation, Low and Middle Income Countries and Resilience were undertaken using PubMed and Psychinfo. Dietary adequacy is critical for growth and development, but current evidence indicates that nutrition supplementation alone is insufficient to foster resilience to protect against, mitigate, and recover from nutritional threats and to promote healthy development. The combination of nutrition interventions with stimulation and responsive care is necessary. Combined nutrition and psychosocial stimulation approaches can potentially work effectively together to promote protective factors and mitigate risks for poor cognitive, motor, social, and affective functioning helping children to adapt in times of adversity. However, there are gaps in our existing knowledge to combine nutrition and psychosocial stimulation interventions effectively and promote these interventions at scale. Research needs to address barriers at the level of family, community, programme, and policy which have prevented thus far the uptake of combined nutrition and psychosocial intervention strategies. Further investigations are needed on how to provide support to caregivers, enabling them to implement appropriate care for feeding and stimulation. Finally, the effect of combined

    1999-01-01

    To assess the dietary intake and nutritional status in children of the tribal areas of Bihar. Cross sectional survey with two stage probability proportional to size sampling. Study covered 396 villages from 17 tribal districts of Bihar. 1847 preschool children (0-6 Years) were studied. 24 hours recall method was used to assess the nutrition intake and anthropometric measurements included height and weight. Nutritional intake was compared with Indian Council of Medical Research recommended dietary allowances (RDA) and nutritional status assessed by SD classification. The intake of protein was broadly in line with the recommended dietary allowances (RDA) in all age groups among children. However, the average intake of energy and other nutrients was lower in allage groups as compared to RDA. Calorie deficiency was 38% whereas protein deficiency was about 19%. More than half of the children were caloric deficient in Katihar, Bokaro, Godda and Singhbhum (east and west). The overall prevalence of stunting was about 60% and underweight about 55% and was comparable in boys and girls. However, wasting was more frequent in girls (urban - 34.5% vs. 16.3% and rural - 34.9% vs 18%). The level of malnutrition was not very different in rural and urban areas. The nutritional status and dietary intakes of tribal children in Bihar is very poor. Urgent remedial measures are required in this context, particularly on a war footing in especially vulnerable districts identified by this survey.

    Competitive diving involves grace, power, balance, and flexibility, which all require satisfying daily energy and nutrient needs. Divers are short, well-muscled, and lean, giving them a distinct biomechanical advantage. Although little diving-specific nutrition research on performance and health outcomes exists, there is concern that divers are excessively focused on body weight and composition, which may result in reduced dietary intake to achieve desired physique goals. This will result in low energy availability, which may have a negative impact on their power-to-weight ratio and health risks. Evidence is increasing that restrictive dietary practices leading to low energy availability also result in micronutrient deficiencies, premature fatigue, frequent injuries, and poor athletic performance. On the basis of daily training demands, estimated energy requirements for male and female divers are 3,500 kcal and 2,650 kcal, respectively. Divers should consume a diet that provides 3-8 g/kg/day of carbohydrate, with the higher values accommodating growth and development. Total daily protein intake (1.2-1.7 g/kg) should be spread evenly throughout the day in 20 to 30 g amounts and timed appropriately after training sessions. Divers should consume nutrient-dense foods and fluids and, with medical supervision, certain dietary supplements (i.e., calcium and iron) may be advisable. Although sweat loss during indoor training is relatively low, divers should follow appropriate fluid-intake strategies to accommodate anticipated sweat losses in hot and humid outdoor settings. A multidisciplinary sports medicine team should be integral to the daily training environment, and suitable foods and fluids should be made available during prolonged practices and competitions.

  19. Thiamine Deficiency Induced Neurochemical, Neuroanatomical, and Neuropsychological Alterations: A Reappraisal

    Directory of Open Access Journals (Sweden)

    Raffaele Nardone

    2013-01-01

    Full Text Available Nutritional deficiency can cause, mainly in chronic alcoholic subjects, the Wernicke encephalopathy and its chronic neurological sequela, the Wernicke-Korsakoff syndrome (WKS. Long-term chronic ethanol abuse results in hippocampal and cortical cell loss. Thiamine deficiency also alters principally hippocampal- and frontal cortical-dependent neurochemistry; moreover in WKS patients, important pathological damage to the diencephalon can occur. In fact, the amnesic syndrome typical for WKS is mainly due to the damage in the diencephalic-hippocampal circuitry, including thalamic nuclei and mammillary bodies. The loss of cholinergic cells in the basal forebrain region results in decreased cholinergic input to the hippocampus and the cortex and reduced choline acetyltransferase and acetylcholinesterase activities and function, as well as in acetylcholine receptor downregulation within these brain regions. In this narrative review, we will focus on the neurochemical, neuroanatomical, and neuropsychological studies shedding light on the effects of thiamine deficiency in experimental models and in humans.

  20. IAEA/WHO programme on iron nutrition

    International Nuclear Information System (INIS)

    Dudley, R.A.

    1973-01-01

    For many years, both the World Health Organization and the International Atomic Energy Agency have sponsored research related to the subject of iron deficiency in humans. About four years ago their collective efforts were brought into focus in a co-ordinated research programme on iron nutrition. This may not yet be the 'large co-operative effort' which Dr. Moore envisioned, but it has the same objectives. Through modest financial assistance, the central supply of certain essential materials, and the effective exchange of information among collaborating scientists, the programme attempts to understand the state of iron nutrition in several societies and to identify means by which it can be improved. For two reasons, the emphasis of this co-ordinated programme is on iron nutrition in the developing countries. First, nutrition in general and iron nutrition in particular are more often marginal in these countries than in the developed countries, and second, the developing countries have fewer resources of their own to devote to this problem

Unilever, as a global food business, has a simple approach to nutrition strategy: 'better products' help people to enjoy 'better diets' and live 'better lives.' For 'Better Products,' Unilever strives to improve the taste and nutritional qualities of all our products. By 2020, we commit to double the proportion of our entire global portfolio meeting the highest nutrition standards, based on globally recognised dietary guidelines. Unilever sets a clear plan to achieve reduction of sodium, saturated fat, trans fat, sugar, and calories in our products. Unilever developed fortified seasoning and spread products in 2013 for Vietnam, Indonesia, and the Philippines in collaboration with government bodies to address nutrient deficiencies. For 'Better Diets and Better Lives,' Unilever uses targeted communication to raise awareness and promote behavior change for healthy lifestyles. We committed to full nutrition labeling on our food products by 2015. We contribute experience to science-based regional initiatives on product labeling as well as nutrient profiling. Unilever collaborated with international, regional and country bodies to promote consumer understanding and food accessibility on public health priorities such as proper salt consumption, healthier meals, and employee well-being programs. Looking ahead, we are continuing to improve the nutritional profile of our products as well as our communication to improve diets and lives. Collaboration between industry, government and public health organizations is needed to address complex diet and life style issues.

    Full Text Available Adult growth hormone deficiency (AGHD is being recognized increasingly and has been thought to be associated with premature mortality. Pituitary tumors are the commonest cause for AGHD. Growth hormone deficiency (GHD has been associated with neuropsychiatric-cognitive, cardiovascular, neuromuscular, metabolic, and skeletal abnormalities. Most of these can be reversed with growth hormone therapy. The insulin tolerance test still remains the gold standard dynamic test to diagnose AGHD. Growth hormone is administered subcutaneously once a day, titrated to clinical symptoms, signs and IGF-1 (insulin like growth factor-1. It is generally well tolerated at the low-doses used in adults. Pegylated human growth hormone therapy is on the horizon, with a convenient once a week dosing.

  11. Position of the academy of nutrition and dietetics: nutrition security in developing nations: sustainable food, water, and health.

    It is the position of the Academy of Nutrition and Dietetics that all people should have consistent access to an appropriately nutritious diet of food and water, coupled with a sanitary environment, adequate health services, and care that ensure a healthy and active life for all household members. The Academy supports policies, systems, programs, and practices that work with developing nations to achieve nutrition security and self-sufficiency while being environmentally and economically sustainable. For nations to achieve nutrition security, all people must have access to a variety of nutritious foods and potable drinking water; knowledge, resources, and skills for healthy living; prevention, treatment, and care for diseases affecting nutrition status; and safety-net systems during crisis situations, such as natural disasters or deleterious social and political systems. More than 2 billion people are micronutrient deficient; 1.5 billion people are overweight or obese; 870 million people have inadequate food energy intake; and 783 million people lack potable drinking water. Adequate nutrient intake is a concern, independent of weight status. Although this article focuses on nutritional deficiencies in developing nations, global solutions for excesses and deficiencies need to be addressed. In an effort to achieve nutrition security, lifestyles, policies, and systems (eg, food, water, health, energy, education/knowledge, and economic) contributing to sustainable resource use, environmental management, health promotion, economic stability, and positive social environments are required. Food and nutrition practitioners can get involved in promoting and implementing effective and sustainable policies, systems, programs, and practices that support individual, community, and national efforts.

  12. Epidemiology of SHOX deficiency.

    Deletion of short stature homeobox-containing (SHOX) gene, in the pseudoautosomal region (PAR1) of X and Y chromosomes, is an important cause of short stature. Homozygous loss of SHOX results in the more severe Langer mesomelic dysplasia, while SHOX haploinsufficiency cause a wide spectrum of short stature phenotypes, including patients with Turner syndrome, Leri Weill dyschondrosteosis (LWD), and idiopathic short stature (ISS). In Turner syndrome, haploinsufficiency of SHOX gene, as well as short stature, are present in 100%; nevertheless, SHOX deficiency accounts for only two-thirds of Turner patients' short stature. In LWD the prevalence of SHOX gene anomalies varies from 56% to 100%. This wide range might be due to different factors such as selection criteria of patients, sample size, and method used for screening SHOX mutations. The real challenge is to establish the prevalence of SHOX deficiency in ISS children given that published studies have reported this association with a very broad frequency range varying from 1.5% to 15%. An important variable in these studies is represented by the method used for screening SHOX mutations and sometimes by differences in patient selection. Short stature is present by definition in 3 out of 100 subjects; if we consider a frequency of SHOX defects of 3% among ISS, we should expect a population prevalence of 1 in 1000. This prevalence would be higher than that of GH deficiency (1:3,500) and of Turner syndrome (1:2,500 females), suggesting that SHOX deficiency could be one of the most frequent monogenetic causes of short stature.

  13. Biotin and biotinidase deficiency

    Biotin is a water-soluble vitamin that serves as an essential coenzyme for five carboxylases in mammals. Biotin-dependent carboxylases catalyze the fixation of bicarbonate in organic acids and play crucial roles in the metabolism of fatty acids, amino acids and glucose. Carboxylase activities decrease substantially in response to biotin deficiency. Biotin is also covalently attached to histones; biotinylated histones are enriched in repeat regions in the human genome and appear to play a role...

  14. Radioisotopes as tools in food and nutrition research

    In the Philippines as in many developing countries, protein-energy malnutrition, vitamin A, iron and iodine deficiencies continue to pose serious health problems particularly in children, pregnant and lactating women. These problems as per World Declaration on Nutrition adopted by government ministers and senior policy makers from more than 150 countries, should be dramatically reduced if not virtually eliminated by the year 2000. The rapid advances in isotope techniques contributed significantly to a greater and better understanding of the quantitative relationships of diets, nutrients and health. While it is recognized that isotopic techniques have a wide variety of application in human nutrition, this paper will focus on how radioisotopes may be applied in clarifying nutritional problems specifically iron, iodine and vitamin A deficiency and how such knowledge is applied in developing practical methods for eliminating them.

    The aim of this study was to assess the incidence, clinical presentation, and outcomes of neurologic disorders secondary to vitamin B deficiencies following bariatric surgery. Patients at a single academic institution who underwent bariatric surgery and developed neurologic complications secondary to low levels of vitamins B1, B2, B6, and B12 between the years 2004 and 2015 were studied. In total, 47 (0.7%) bariatric surgical patients (Roux-en-Y gastric bypass n = 36, sleeve gastrectomy n = 9, and duodenal switch n = 2) developed neurologic manifestations secondary to vitamin B deficiencies. Eleven (23%) patients developed postoperative anatomical complications contributed to poor oral intake. Median duration to onset of neurologic manifestation following surgery was 12 months (IQR, 5-32). Vitamin deficiencies reported in the cohort included B1 (n = 30), B2 (n = 1), B6 (n = 12), and B12 (n = 12) deficiency. The most common manifestations were paresthesia (n = 31), muscle weakness (n = 15), abnormal gait (n = 11), and polyneuropathy (n = 7). Four patients were diagnosed with Wernicke-Korsakoff syndrome (WKS) which was developed after gastric bypass (n = 3) and sleeve gastrectomy (n = 1). Seven patients required readmission for management of severe vitamin B deficiencies. Overall, resolution of neurologic symptoms with nutritional interventions and pharmacotherapy was noted in 40 patients (85%). The WKS was not reversible, and all four patients had residual mild ataxia and nystagmus at the last follow-up time. Nutritional neurologic disorders secondary to vitamin B deficiency are relatively uncommon after bariatric surgery. While neurologic disorders are reversible in most patients (85%) with vitamin replacements, persistent residual neurologic symptoms are common in patients with WKS.

    Full Text Available ABSTRACT Objective To determine the current nutritional status in Latin America and the Caribbean (LAC and identify data gaps and trends in nutrition surveillance. Methods A systematic Internet search was conducted to identify official sources that allowed for monitoring of LAC countries’ nutritional status, including progress toward World Health Organization Global Nutrition Targets 2025. Reports from national nutrition surveillance systems and reports on nationally representative surveys were collected and collated to 1 analyze nutritional status, based on life-course anthropometric indicators and biomarkers, and 2 identify gaps in data availability and trends in nutritional deficiencies. Information on iron, vitamin A, iodine, folate, and vitamin B12 deficiency was also collected and collated. Results Twenty-two of the 46 LAC countries/territories (48% had information on undernutrition (stunting, underweight, and wasting in children under 5 years old and women of reproductive age (WRA. Seventeen countries (38% had information on anemia in children under 5 years old and WRA, and 12 (27% had information on anemia in pregnant women. Although overall nutritional status has improved in the past few decades in all countries in the region, some LAC countries still had a high prevalence of stunting and anemia in children and WRA. Overweight affected at least 50% of WRA in nine countries with available data, and was increasing in children. Data for school-age children, adolescents, adult males, and older adults were scarce in the region. Conclusions Overall nutritional status has improved in the LAC countries with available information, but more efforts are needed to scale up nutrition-sensitive and nutrition-specific interventions to tackle malnutrition in all its forms, as stunting, anemia, and vitamin A deficiency are still a public health problem in many countries, and overweight is an epidemic. Nutrition information systems are weak in the
