ASSOCIATION OF BIRTH WEIGHT AND TIME OF BREASTFEEDING WITH CURRENT NUTRITIONAL STATUS OF CHILDREN

Objetivo: Analisar a relação entre o peso ao nascer (PN) e o tempo de aleitamento materno (AM) com o atual estado nutricional de crianças de dois a seis anos de idade. Métodos: Estudo observacional, quantitativo e do tipo transversal, realizado com crianças, independentemente do sexo, com idades entre dois a seis anos, matriculadas em sete escolas de educação infantil da rede municipal de um município do interior do Rio Grande do Sul (RS), no período de junho a agosto de 2014. Participaram 353 crianças, aferindo-se peso e altura, após os pais terem respondido a um questionário de Peso ao Nascer (PN) e tempo de aleitamento materno. Resultados: A média de aleitamento materno exclusivo foi de 3,47 ± 2,81 meses. A maioria das crianças (50,7%, n=179) encontrou-se em risco de sobrepeso ou sobrepeso para a idade, conforme o Índice de Massa Corporal (IMC). O PN apresentou correlação positiva com a altura atual (r=0,164, p=0,002) e com o peso atual (r=0,180, p=0,001). O PN foi significativamente maior entre os meninos (p=0,003), e o tempo de AM associado à alimentação complementar foi significativamente maior entre as meninas (p=0,024). Conclusão: Os resultados sugerem que o peso ao nascer influencia o ganho de peso nos seis primeiros anos de vida, com maior destaque para os meninos; e o tempo de amamentação associado à alimentação complementar foi maior entre as meninas.

NUTRITIONAL COUNSELING OFFERED TO CHILDREN AND ADOLESCENTS WITH DISABILITIES

Objective: To evaluate the nutritional counseling offered to children and adolescents with disabilities in the municipality of Santa Cruz, RN, Brazil. Methods: Observational, crosssectional, population-based study, developed from May to December 2013, with 102 children and adolescents attending a Children’s Rehabilitation Center. We conducted socioeconomic, demographic, health and lifestyle assessments, and evaluated the received nutritional assistance (whether they had received nutritional counseling from any health professional in relation to food and nutrition, how often it occurred and which professional conducted such counseling). Results: Only 37% (n=37) of parents had received some nutritional guidance. Regarding the frequency of counseling, only 11.8% (n=4) of the youngsters received it 7 or more times/year; 23.5% (n=8) received it 2 to 6 times/year; and most (64.7 %, n=22) received it 1 time/year or less. The length of the nutritional counseling was short: the majority (64.7%, n=22) received only one guidance session throughout the whole period attending the institution, and less than 15% (n=5) received counseling for more than six consecutive months. For the majority (73.5%, n=25), the amount of time receiving nutritional guidance has not reached half of the monitoring period. Nutritional counseling was carried out mainly by nutritionists (89.2%, n=33). Conclusion: There was a low frequency of nutritional counseling directed specifically to the disabilities presented by the participants. When such activity was conducted, it occurred irregularly during the participant´s follow-up, only during a short period of time, and lacking connection with the monitoring by the multidisciplinary team.

Effects of organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries ‘Corona’, ‘Legacy’, and ‘Liberty’

Organic farming does not allow using certain inputs, such as N, which differ in nutrient release rates and dynamics. To evaluate the effect of different organic fertilizers on the vegetative, nutritional, and productive parameters of blueberries ( Vaccinium corymbosum L.), a pot experiment was conducted in three consecutive seasons in a sandy soil of south-central Chile using ‘Corona’, ‘Legacy’ and ‘Liberty’. The following fertilizers were evaluated: compost (CM), Purely Grow (PG), Purely Lysine (PL), Fertil (F), blood meal (BM), lupine meal (LM), along with a control treatment without fertilization (C) and two conventional treatments with urea (CF) and sodium nitrate (S). Results indicate that vegetative growth and leaf N concentration prior to senescence were different among cultivars in the three evaluated seasons. The highest leaf N concentration was recorded in ‘Corona’ followed by ‘Legacy’ and ‘Liberty’ while levels tended to increase in the seasons. Quick-release N sources had greater effects on these parameters but with differences among cultivars. Fruit yield and weight were higher in ‘Corona’ followed by ‘Legacy’ and ‘Liberty’. Fruit yield was generally higher when using LM and F and showed no effect on fruit weight. Leaf chlorophyll content was higher in ‘Corona’ followed by ‘Legacy’ and ‘Liberty’, which increased when using CF, LM, BM, and PG. Finally, the organic fertilizer and blueberry cultivar that obtained the highest values for most of the evaluated parameters were LM and Corona, respectively.

Nutritional profile and yield of oyster mushroom cultivated on selected agricultural wastes

Research on mushroom production and products is gaining more grounds globally and in particular Nigeria. This study was carried out to determine nutritional relationship between the substrate used for cultivation and the fruiting body on each of the substrates. Agro-wastes, namely: palm ( Elaeis guineensis ) fruit shaft, plantain ( Musa paradisiaca ) leaves, sawdust and kenaf ( Hibiscus cannabinus ) stem, were assessed for suitability as substrates for cultivation of oyster mushroom ( Pleurotus floridanus Singer ). The spawn of the mushroom was used to inoculate each of the substrates, using a complete randomised design, with five replicates for each substrate. Results showed that all the substrates supported mycelia growth and development of fruiting bodies of the fungus. There were significant differences (P<0.05) among substrates in terms of number of days to complete mycelia run, with the least recorded in palm fruit shaft (25.20), and the highest in kenaf (32.40). Total yield also differed significantly (P<0.05), with the highest in palm fruit shaft (51.4 g 100 g-1) and lowest in plantain leaves (6.0 g 100 g-1). There was also significant difference (P<0.05) in the nutritional content of fruiting bodies, the highest fat content being on plantain leaves (1.72 g 100 g-1) and the lowest on palm fruit shaft (0.55 g 100 g-1). The trend was similar for mushroom substrates, plantain leaves having (2.55 g 100 g-1) and palm fruit shaft, (0.41g 100 g-1). Starch content for fruiting bodies was highest on sawdust (5.31 g 100 g-1) and lowest on kenaf (2.66 g 100 g-1), while for mushroom substrates, kenaf was (0.33g 100 g-1) and palm fruit shaft was (4.45g 100 g-1). There was a positive correlation (r = 0.24) between the nutrient of fruiting bodies and that of the substrate on which it was cultivated.

Experiences of health professionals with nutritional support of critically ill patients in tertiary hospitals in Malawi

Background Nutritional support is a recognized determinant of outcome in critically ill patients. Development of critical care services in low-income countries has not been accompanied by certain appropriate ancillary services and interventions, such as adequate nutritional support. This study was designed to investigate the experiences of health professionals who have provided nutritional supportive care to critically ill patients admitted to two major central hospitals in Malawi, with the aim of identifying the common practices in nutritional support in these settings. Materials and Methods A cross-sectional study in which 50 health professionals working in intensive care and high dependency units, admitting both adult and pediatric patients, were interviewed using a semi-structured questionnaire. Data were coded and then analyzed using SPSS version 16.0. Responses between the two hospitals were compared using Fisher’s exact test. Results There was no difference in the composition of respondents from the two hospitals. About 60% of respondents had had experience with nutritional supplementation in their patients—mainly enteral. The most commonly used formulations were the “ready-to-use therapeutic feeds,” followed by modified milk. A high percentage of respondents (40%) reported having used dextrose solution as the sole nutritional supplement. Lack of in-service training, nonexistent nutrition protocols pertaining to acutely and critically ill patients, and a lack of clinical nutritionists were the major challenges identified. Conclusion Knowledge of nutrient supplementation was poor among the respondents. The use of ready-to-use therapeutic feeds was quite common, although there is no evidence of its effectiveness in care of acutely critically ill patients. There is a need to establish nutritional support teams in these tertiary hospitals. Clinical nutritionists would ideally help train and play leadership roles in such teams, who would be responsible for assessing patients for their nutritional needs, and ensuring that the feeds provided to patients are appropriate and adequate for their needs.

Anthropometric characteristics and the burden of altered nutritional status among neuropsychiatric patients at Zomba Mental Hospital in Zomba, Malawi

Objective To determine the prevalence of overnutrition and undernutrition among neuropsychiatric inpatients and outpatients at Zomba Mental Hospital in Zomba, Malawi. Methods In this analytical cross-sectional study (n = 239), data were collected from psychiatric patients who were either inpatients (n = 181) or outpatients (n = 58) at Zomba Mental Hospital, which is the largest mental health facility in Malawi. Information was collected about patient demographics, anthropometric data, dietary information, and tobacco and alcohol use, among other variables. Data were entered and analysed in SPSS 16.0 (SPSS Inc., Chicago, IL, USA). Means were generated and compared between male and female patients, and between inpatients and outpatients. Results The study recruited 158 male and 81 female patients, with mean ages of 31.24 ± 11.85 years and 33.08 ± 15.18 years (p = 0.328), respectively. Male patients were significantly taller (165.27 ± 7.25 cm) than female patients (155.30 ± 6.56 cm) (p < 0.001); were significantly heavier than females (60.02 ± 10.56 kg versus 55.64 ± 10.53 kg); and had a significantly lower mean body mass index (BMI) than females (21.87 ± 3.21 vs. 23.01 ± 3.78) (p = 0.016). Overweight and obese patients comprised 17.6% of the participants, and 8.8% were underweight. There were no significant differences in the prevalence of overweight, obesity, and underweight between male and female participants, or between inpatients and outpatients. Conclusion Our study—the first one of its kind in Malawi—characterised the anthropometry of neuropsychiatric patients at a major metal health facility in Malawi, and has shown a high proportion of overweight patients and a notable presence of underweight patients among them. Being overweight or obese is a risk factor for metabolic disorders. Being underweight may aggravate mental illness or disturb the effect of medication. There is need, therefore, to include nutrition screening and therapeutic or supplementary feeding as part of a comprehensive care and treatment plan for neuropsychiatric patients.

NUTRITIONAL COMPOSITION AND ANTIOXIDANT PROPERTIES OF RAPHIONACME SPLENDENS (SCHL.) TUBERS

People of Western Kordofan (Sudan) are endowed with a deep knowledge concerning the use of wild plants. Tubers of Raphionacme splendens Schl. subspecies splendens Flickr (family Apocynaceae), locally known as Elfayo, are used as a food reserve during times of famine or poor harvest. The aim of this study was to analyze the nutritional composition and antioxidant capacity of root tubers of R. splendens. Samples were collected from South-West Kordofan. Analyses included determination of moisture, carbohydrate, crude protein, fat, fibre, ash, minerals, vitamin C, amino acids and fatty acids composition. Antioxidant activity was determined by the DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2.2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) assays. The total phenolic content was also assessed. The results, which are referred to as (%) dry weight, showed that the tubers contained 3.2% protein, 18% carbohydrate, 0.5% lipid, 2.4% crude fibre, 3.5% ash, 79.2% moisture and gross energy 101.7 kJ/g. The total amino acids were 10776 mg/100g where the essential amino acids represented 28.2%. The more abundant essential amino acids were leucine (792mg/100g), isoleucine (712mg/100g) and threonine (536mg/100g). Methionine and lysine were the limiting amino acids. Minerals were potassium (259mg/100g), calcium (183mg/100g), magnesium (64mg/100g), phosphorus (37mg/100g), copper (3.6mg/100g), manganese (2.4mg/100g), zinc (1.8mg/100g) and iron (1.2mg/100g). Total saturated fatty acids were 45.6% whereas total unsaturated fatty acids were 54.4%. Oleic acid (32.56%) and palmitic acid (30.23%) were the most abundant fatty acids. Tubers displayed good antioxidant activity with IC50 values 0.987 and 1.559mg/mL against DPPH and ABTS radicals respectively. Vitamin C was 31.5mg/100g and total phenolic content was 60mg gallic acid equivalent (GAE) per 100g dry sample and they could be the main contributor to the antioxidant capacity of the tubers. In conclusion, the results of this study suggested that tubers of R. splendens could have beneficial effect for food and/or nutraceutical application for normal growth and adequate protection against diseases associated with reactions of free radicals.

NUTRITIONAL AND AMINO ACID ANALYSIS OF RAW, PARTIALLY FERMENTED AND COMPLETELY FERMENTED LOCUST BEAN ( Parkia biglobosa ) SEEDS

The nutritional and amino acid analysis of raw and fermented seeds of Parkia biglobosa were carried out. Parameters investigated include moisture, crude protein, crude fat, ash, crude fibre and mineral contents; and the effect of the degree of fermentation on these parameters was also investigated. The amino acid compositions of all the samples were evaluated and amino acid quality determined by calculating amino acid scores and the predicted protein efficiency ratio (P-PER). Results showed that the proximate composition was significantly affected by fermentation, although there was little difference between the parameters for the partially fermented and completely fermented samples. Based on dry matter percentage, protein content was in the 39.77 – 43.74 % range while crude fibre ranged between 5.55 – 7.42 %. The ash content was lowest in the raw sample (2.34 %), while the fermented samples had ash contents between 4.27 and 8.33 % for the fully fermented and the partially fermented seeds, respectively. The fat content increased from 8.65 % in the raw seed to 24.4 % and 27.6 % for the partially and completely fermented samples, respectively. Results of the amino acid analysis showed that the partially fermented sample had the lowest quantities of all amino acids determined and had lysine as the limiting amino acid, whereas the raw and completely fermented samples had very similar amino acid profile with amino acid scores of 100, indicating that there are no limiting amino acids. All the samples were rich in essential amino acids. The P-PER also showed that the partially fermented sample had the lowest protein efficiency while the raw seed had the highest. Mineral contents generally increased from the raw, through the partially fermented, to the completely fermented seeds and results showed the samples to be good sources of potassium (K), calcium (Ca), manganese (Mn) and copper (Cu) in addition to being complementary sources of other metals. Locust bean seed does not accumulate lead and is, therefore, safe for consumption without the potential of food poisoning.
