Riesgos nutricionales en lactantes que no reciben lactancia materna exclusiva en los primeros seis meses de la vida / Nutritional risks among not exclusively breastfed infants in the first 6 months of life

La leche humana es el alimento ideal para los lactantes y sus beneficios se manifiestan en el corto y el largo plazo. En situaciones de crisis es cuando más se debe enfatizar en la lactancia materna, considerada una de las intervenciones más costo-efectivas para reducir la morbimortalidad infantil. Más allá de las múltiples ventajas que la leche humana tiene en relación con el vínculo madre-hijo y las capacidades biológicas e inmunológicas, lo más importante es que la leche materna cubre todas las necesidades nutricionales. Cuando la lactancia materna no es posible, la Organización Mundial de la Salud recomienda, como primera opción, las fórmulas infantiles. La segunda opción es leche de vaca (LV) diluida, que conlleva riesgos de deficiencias nutricionales en el lactante que deben ser monitoreadas en forma estrecha y oportunamente subsanadas. Los principales riesgos de deficiencias en el lactante que recibe LV diluida son las de hierro, cinc, vitaminas A, D, C y E, aminoácidos y ácidos grasos esenciales

Breast milk is the ideal food for infants and its benefits can be observed in the short and long term. In crisis situations, breastfeeding should be promoted the most because it is one of the most cost-effective interventions aimed at reducing infant morbidity and mortality. In addition to the multiple advantages of breast milk in the mother-child bond and biological and immune properties, the most relevant characteristic of breast milk is that it covers all nutritional needs. When breastfeeding is not possible, the World Health Organization recommends infant formula as the first option. The second option is diluted cow's milk, which entails the risk for nutritional deficiency that should be strictly monitored and timely resolved. When infants are fed with diluted cow's milk, they are mainly at risk for iron, zinc, vitamin A, D, C, and E, amino acid, and essential fatty acid deficiency.

A comparative study of efficacy, safety and compliance of oral iron versus intravenous iron sucrose in treatment of iron deficiency anaemia of pregnancy

Background: Iron deficiency anemia is the most common form of anemia and nutritional disorder worldwide. Oral iron therapy and blood transfusion has many drawbacks like noncompliance and risk of transmittable infections and transfusion reaction. The modern alternative therapy is treatment with intravenous iron. Present study compares the efficacy, safety and tolerability between intravenous iron sucrose and oral iron in iron deficiency anemia during 20-36 weeks of pregnancy.Methods: It was a randomized controlled study between December 2017 to September 2019. 200 patients attending antenatal OPD in Al Ameen Medical College, with haemoglobin levels between 7-9.9 gm/dl and serum ferritin of <15 ng/ml were enrolled. In intravenous group, 200 mg iron sucrose in 100ml normal saline was infused alternate day till the required dose was met. The oral group received 200 mg of oral iron ascorbate along with folic acid 1.5 mg per day for 6 weeks.  Treatment efficacy was assessed by Hb and serum ferritin after 3 and 6 weeks.Results: Out of 200 patients, an increase in Hb was observed in both groups, rising from 9.7 g/dl to 10.3 g/dl and 10.9 g/dl after 3 weeks and 6 weeks respectively in oral group and from 8.6 g/dl to 9.8 g/dl and 10.8 g/dl after 3 weeks and 6 weeks respectively in intravenous group. Similar results were seen in ferritin levels. Rise in Hb and ferritin levels were greater in intravenous group than in oral group.Conclusions: Intravenous iron sucrose appears to be a better treatment option in comparison with oral iron, without serious side effects, better compliance and improved efficacy in correction of anaemia of pregnancy.

OBJETIVO: Estimar o consumo de energia e nutrientes e a prevalência de ingestão inadequada de micronutrientes entre adultos brasileiros. MÉTODOS: Foram analisados dados do Inquérito Nacional de Alimentação da Pesquisa de Orçamento Familiar 2008-2009. O consumo alimentar foi avaliado por dois dias de registro alimentar não consecutivos. Um total de 21.003 indivíduos (52,5% mulheres) entre 20 e 59 anos de idade participou do estudo. A ingestão usual de nutrientes foi estimada pelo método proposto pelo National Cancer Institute. As prevalências de ingestão inadequada de micronutrientes foram obtidas pelo método da necessidade média estimada (EAR) como ponto de corte. Para manganês e potássio, a Ingestão Adequada (AI) foi usada como ponto de corte. A ingestão de sódio foi comparada com o nível de ingestão máximo tolerável (UL). A prevalência de inadequação da ingestão de ferro foi determinada por abordagem probabilística. Os dados foram analisados de acordo com a localização do domicílio (área urbana ou rural) e as macrorregiões do país. RESULTADOS: A média do consumo energético foi de 2.083 kcal entre os homens e 1.698 kcal entre as mulheres. Prevalências de inadequação maiores ou iguais a 70% foram observadas para cálcio entre os homens e magnésio, vitamina A, sódio em ambos os sexos. Prevalências maiores ou iguais a 90% foram encontradas para cálcio entre as mulheres e vitaminas D e E em ambos os sexos. Prevalências menores que 5% foram encontradas para ferro entre os homens e niacina para homens e mulheres. No geral, a prevalência de ingestão inadequada foi mais acentuada na área rural e na região Nordeste. CONCLUSÕES: O consumo de energia é maior entre indivíduos residentes em áreas urbanas e da região Norte. Os grupos com maior risco de ingestão inadequada de micronutrientes são as mulheres e os que residem na área rural e na região Nordeste.

OBJECTIVE: To estimate energy and nutrient intake and prevalence of inadequate micronutrient intake among Brazilian adults. METHODS: Data from the National Dietary Survey, from the 2008-2009 Household Budget Survey, were used. Food consumption was evaluated through food record on two non-consecutive days. A total of 21,003 individuals (52.5% women), between 20-59 years old, participated in the survey. Usual nutrient intake was estimated according to the National Cancer Institute method. The Estimated Average Requirement (EAR) cut-off points were used to determine the prevalence of inadequate micronutrient intake. For manganese and potassium, the Adequate Intake (AI) was used as cut-off. Sodium intake was compared with the Tolerable Upper Intake Level (UL). The probability approach was used to determine the prevalence of inadequate iron intake. The data were analyzed according to the location of the household (urban or rural) and macro regions of Brazil. RESULTS: The mean energy intake was 2,083 kcal among men and 1,698 kcal among women. Prevalence of inadequacy equal to or greater than 70% were observed for calcium among men and magnesium, vitamin A, and sodium among both men and women. Prevalence equal to or greater than 90% were found for calcium in women and vitamins D and E in both genders. Prevalence lower than 5% were found for iron in men and for niacin in men and women. In general, prevalence of inadequate intake was higher in the rural area and in the Northeast region. CONCLUSIONS: Energy intake was higher among individuals who live in urban areas and in the North region. The greatest risk groups of inadequate micronutrient intake were women and those living in rural areas and in the Northeast region.

Inadequação do consumo de nutrientes entre adolescentes brasileiros / Inadequate nutrient intake in Brazilian adolescents / Consumo inadecuado de nutrientes entre adolescentes brasileños

OBJETIVO: Estimar o consumo de energia e nutrientes e a prevalência de inadequação da ingestão de micronutrientes entre adolescentes brasileiros. MÉTODOS: Amostra probabilística composta por 6.797 adolescentes (49,7% do sexo feminino) entre dez e 18 anos de idade foi avaliada no Inquérito Nacional de Alimentação, 2008-2009. Os fatores de expansão, a complexidade do desenho da amostra e a correção da variabilidade intrapessoal do consumo foram considerados. A prevalência de inadequação de consumo de micronutrientes foi estimada pela proporção de adolescentes com ingestão abaixo da necessidade média estimada. Para o sódio, estimou-se a prevalência de consumo acima do valor de ingestão máxima tolerável. RESULTADOS: A média de consumo de energia variou de 1.869 kcal, observada nas adolescentes de 10 a 13 anos, a 2.198 kcal, estimada para os adolescentes de 14 a 18 anos. Os carboidratos forneceram 57% da energia total, os lipídios, 27% e as proteínas, 16%. As maiores prevalências de inadequação foram observadas para cálcio (> 95%), fósforo (entre 54% e 69%) e vitaminas A (entre 66% e 85%), E (100%) e C (entre 27% e 49%). Mais de 70% dos adolescentes apresentaram consumo de sódio superior à ingestão máxima tolerável. CONCLUSÕES: As médias de consumo energético e a distribuição de macronutrientes eram adequadas, mas foram observadas elevadas prevalências de inadequação no consumo de vitaminas e minerais, destacando-se consumo de sódio muito acima do recomendado, consumo de cálcio reduzido e nas adolescentes de 14 a 18 anos foi observada importante inadequação na ingestão de ferro.

OBJECTIVE: To assess energy and nutrient consumption and the prevalence of inadequate micronutrient intake among Brazilian adolescents. METHODS: A random sample composed of 6,797 adolescents (49.7% girls), between 10 and 18 years old, was evaluated in the first National Dietary Survey, part of the Household Budget Survey carried out in 2008-2009. Expansion factors, sample complexity design and correction of intraindividual variability were considered. The prevalence of inadequate micronutrient intake was based on the proportion of adolescents with intake below the Estimated Average Requirement (EAR). The prevalence of intake above the Tolerable Upper Intake Level (UL) was estimated for sodium. RESULTS: The mean energy intake ranged between 1,869 kcal (10 to 13 year old females) and 2,198 kcal (14 to 18 year old males). Of the total energy intake, 57% came from carbohydrates, 27% from lipids and about 16% from proteins. Inadequacies were higher for calcium (> 95%), phosphorous (54% to 69%) and vitamins A (66% to 85%), E (100%) and C (27% to 49%). More than 70% of adolescents reported sodium intake above the UL. CONCLUSIONS: Mean energy consumption and distribution of macro-nutrients were adequate, but prevalence of inadequate vitamin and mineral intake were high and notable consumption of sodium above the recommended levels, low levels of calcium consumption and, in 14 to 18 year old females, important inadequacies in iron intake were found.

CONCLUSIÓN: Los promedios de consumo energético y la distribución de macronutrientes eran adecuados, sin embargo, se observaron elevadas prevalencias de consumo inadecuado de vitaminas y minerales, destacándose el consumo de sodio muy por encima de lo recomendado, consumo de calcio reducido y en las adolescentes de 14 a 18 años fue observada importante ingestión inadecuada de hierro.

The Assessment for Nutrient Intakes of Korean Patients with Heart Failure

The prevalence of heart failure (HF) is increasing globally and growing evidence has shown that dietary factors play an important role in preventing and improving prognosis of HF. However, little data on nutrient intake in Korean HF patients which are available to develop dietary guidelines for HF. The aims of this study were to estimate nutrient intake in 78 HF patients and evaluate whether the estimated nutrient intake is appropriate compared to dietary reference intake for Koreans. Data are presented as the ratio of actual intake and estimated average requirement (EAR) for each nutrient. The result showed that the average nutrient intakes including total energy and protein met EAR in total patients. However, the deficiencies in mineral and vitamin intakes were found. Moreover, the proportion of subjects with lower intake than EAR was substantial. The results showed that the proportion of male HF patients with inferior intakes to EAR in calcium, potassium (compared to adequate intake: AI), folate and vitamin B12 were 38%, 79%, 38%, and 65%, respectively. Also, the proportion of female HF patients with inferior intakes to EAR in calcium, potassium (compared to AI), folate and vitamin B12 were 35%, 88%, 38% and 40%, respectively. In particular, the elderly with HF (> or = 70 yrs, n = 28) showed more serious deficiencies in calcium, potassium (compared to AI), folate and vitamin B12. In summary, the intakes of potassium, calcium, folate, and vitamin B12 were not sufficient to meet EAR in HF patients. Furthermore, the proportions of subjects with lower intake than EAR in these nutrients were substantial, raising the possibility that these micronutrients may be involved in the pathogenesis of HF. Practical dietary guideline for HF patients is needed to improve prognosis of HF.
