The aim of this study was to assess the knowledge level on oral health promotion for babies of all mothers (n=60), aged 18-42 years, assisted in the Preventive Dentistry Clinic of the Faculty of Araraquara, at Universidade Estadual Paulista (UNESP), during the period 2005-2008. Methods - An interview was performed using a questionnaire with 18 open and five closed questions about knowledge and practices related to caries prevention as well as demographic information. Methods - The majority believed that breast milk does not cause caries (73,3%), that caries is not a transmissible disease (51,6%) and that anatibiotics cause caries (63,3%). Almost all mothers (93,3%) responded that brushing teeth could prevent the disease, action that should be initiated since first tooth erupts (75%). For 73,3% of the respondents, the use of dental floss should be initiated onle after all deciduous teeth erupt. Results - The majority (83,3%) knew what was fluoride, but a third of them (33,3%) did not know the best time to start using it. The dentist counseling related to oral health of babies was considered imoprtant by 96,7% of mothers. Conslusion - The mothers presented good knowledge about baby's oral hygiene, however, they did not know about other important variables for oral health promotin of babies.

Persistent Organic Pollutants (POPs) are chemical substances extraordinarily toxic and persistent in the environment. Due to these properties, POPs are targets of the Stockholm Convention which aims to provide means to eliminate production and use by encouraging the reduction and, where possible, eliminating the release of these contaminants to the environment. One of the articles of this _Convention aims to assess the basal levels of such substances in the environment to monitor both the reduction of release to the environment, and to assess human exposure, using analyzes of milk and air for example. Although efforts to control POPs production and release to the environment have been made, data about their levels in Brazil are still scarce, mainly in the atmosphere or indoor environment. Considering the permanence of people inside its house, this study presents a method for POP extraction from XAD-2 sorbent employed in indoor air sampling, with identification and quantification by GC-ECD. GC-ECD linear range of the studied analytes, congeners of polychlorinated biphenyls (PCB) (28, 52, 101, 118, 138, 153 and 180), DDTs and their metabolites (DDDs, DDEs) and endosullan (isomers c - and 13 - and metabolite endosulfan sulfate) ranged between 0.5 and 16.0 ng mL-I with r2 > 0.967. The method developing consist of selecting the extraction solvent system by agitation (90 rpm, 1 hour) with n-hexan,e (2 mL) or n-hexane:acetone (1:1, v/v) (2 mL), concentration the extract with a gentle N2 stream, and evaluation of breakthrough with passage or air through the fortified XAD-2 cartridge before extraction, employing a low volume air suction pump (Pump Model 224 universal-PCXR8; 5-5000 mL min-1, SKC Inc., Eighty Four, PA, USA), Calibrator Dry-Cal DC-Lite (BIOS, Butler, NJ, USA)). Two fortification levels were employed, 15 and 30 ng. After selecting n-hexane as extraction solvent, with accuracy and precision ranging...

Para ser competitivo atualmente, o sistema intensivo de produção de suínos deve estar pautado na eficiência. A fim de obter esta eficiência produtiva, o avanço genético das ultimas décadas buscou por fêmeas suínas cada vez mais prolíficas. A prolificidade contudo, veio acompanhada por uma queda no consumo voluntário de alimento por parte das fêmeas, bem como um aumento na produção de leite, e no número de leitões nascidos; o aumento da leitegada, levou a uma redução do peso ao nascimento e um aumento da heterogeneidade entre os leitões. Como forma de contornar o problema, são oferecidas aos leitões dietas formuladas com ingredientes de alto valor biológico a partir dos sete dias de vida, procurando suprir a demanda nutricional do animal durante o período de amamentação e preparar seu sistema digestório para o desmame. Contudo, grande parte das dietas formuladas para os leitões neonatos são oferecidas aos animais em sua forma sólida. Neste projeto, avaliamos os efeitos sobre a performance de leitões neonatos e da performance reprodutiva da fêmea suína do oferecimento de uma dieta líquida para os leitões neonatos, dieta esta que foi disponibilizada aos animais através de um sistema automatizado que realizou a mistura do alimento em sua forma sólida com a água. Para tais avaliações, os leitões ao nascer foram alocados em três grupos distintos, recebendo a dieta em sua forma líquida, em sua forma sólida ou então apenas o leite materno. Foram avaliadas variáveis zootécnicas relacionadas aos leitões, como peso, ganho diário de peso, consumo de ração, conversão alimentar, mortalidade pré-desmame; frequência de dias com diarreia nos leitões em fase de maternidade e creche. Foram eutanasiados leitões aos 14 e aos 28 dias de idade, para a realização do exame morfométrico da altura de vilosidade, profundidade de cripta e a relação entre a altura de vilosidade e profundidade de cripta nas porções do duodeno, jejuno e íleo. Avaliamos também o impacto do uso da dieta líquida sobre o catabolismo sofrido pela fêmea durante a lactação, através da aferição do peso e da espessura de toucinho desta fêmeas durante o período lactacional e também a duração do intervalo desmame estro e a duração do estro subsequente ao desmame. Não verificamos contudo um melhor desempenho zootécnico dos leitões nos períodos de maternidade e creche, tão pouco uma alteração favorável quanto a frequência de dias com diarreia nas duas fases em relação aos leitões que não consumiram nenhum tipo de suplementação. Quanto aos parâmetros morfométricos do intestino delgado, apenas aos 28 dias de idade os leitões que receberam a dieta líquida apresentaram maiores alturas de vilosidades no íleo em relação aos leitões que consumiram a dieta sólida e os animais do grupo controle apresentaram menores profundidades de cripta no mesmo seguimento e idade quando comparados aos demais animais. Contudo, estas alterações não foram o suficiente para garantir diferenças na relação altura de vilosidade:profundidade de cripta. E ainda, a suplementação independente de sua forma não reduziu o catabolismo sofrido pela fêmea suína durante a lactação

Vitamin A is an essential nutrient for many physiological processes such as growth and development, so that their adequate nutritional state is essential during pregnancy and lactation. Lactating women and children in breastfeeding are considered risk groups for vitamin A deficiency and some factors may increase the risk of vitamin A deficiency, such as prematurity. The aim of this work was to evaluate the vitamin A concentration in preterm and term lactating women and newborns by determination of retinol in maternal serum, umbilical cord serum and breast milk collected until 72 hours postpartum. 182 mothers were recruited and divided into preterm group (GPT; n = 118) and term group (GT, n = 64). In preterm group were also analyzed transition milk (7th-15th day; n = 68) and mature milk (30th-55th day; n = 46) samples. Retinol was analyzed by high-performance liquid chromatography (HPLC). Maternal retinol concentration in serum was 48.6 ± 12.3 µg/dL in GPT and 42.8 ± 16.3 µg/dL in the GT (p <0.01). Cord serum retinol was 20.4 ± 7.4 µg/dL in GPT and 23.2 ± 7.6 µg/dL in GT (p> 0.05). Among newborns, 43% of premature and 36% of term had low levels of serum retinol in umbilical cord (<20 µg/dL). In colostrum, the retinol in preterm and term groups had an average of 100.8 ± 49.0 µg/dL and 127.5 ± 65.1 µg/dL, respectively (p <0.05). The retinol average in preterm milk increased to 112.5 ± 49.7 µg/dL in transition phase and decreased to 57.2 ± 23.4 µg/dL in mature milk, differing significantly in all stages (p <0.05). When comparing with the recommendation of vitamin A intake (400 µg/day) GT colostrum reached the recommendation for infants, but in GPT the recommendation was not achieved at any stage. Mothers of premature infants had higher serum retinol than mothers at term; however, this was not reflected in serum retinol of umbilical cord, since premature had lower concentration of retinol. Such condition can be explained due to lower maternal physiological hemodilution and placental transfer of retinol to the fetus during preterm gestation. Comparison of retinol in colostrum showed lower concentrations in GPT; however the transition phase there was a significant increase of retinol content released by the mammary gland of preterm mothers. This situation highlights a specific physiological adaptation of prematurity, likely to more contribute to formation of hepatic reserves of retinol in premature infants.

O leite humano é considerado a base da alimentação da criança, porque para além de ser nutritivo ao fornecer-lhe os nutrientes necessários ao seu crescimento, ainda lhe transmite fatores imunológicos e enzimas, protegendo o lactente contra infeções e alergias, bem como facilita o seu desenvolvimento psicossocial. Pedroso (2011, p.40) ao citar Parizotto e Zorzi (2008) refere também que "amamentar é muito mais do que alimentar a criança. Envolve uma interacção complexa, multi-factorial, entre duas pessoas, que interfere no estado nutricional de uma criança, em sua habilidade de se defender de infecções, em sua fisiologia e no seu desenvolvimento cognitivo e emocional". A criança ao mamar, ao sugar o leite materno realiza movimentos musculares a nível da região oral. Ao realizar esses movimentos, a criança obtém uma tonicidade muscular adequada e uma estimulação da estrutura óssea e dos músculos faciais, o que contribui para o correto desenvolvimento dos órgãos fono-articulatórios, prevenindo alterações de hipo-desenvolvimento, mal oclusões e problemas de articulação (Delgado & Halpern, 2005). Pereira (2008) ao citar (Sousa, 1997) refere que a criança durante a amamentação, aprende a respirar corretamente pelo nariz, evitando amigdalites, pneumonias, entre outras doenças. O aleitamento materno proporciona ao bebé um padrão de respiração correto, favorecendo o encerramento labial e a postura adequada da língua, garantindo a boa relação entre as estruturas do Sistema Estomatognático (Tollara et al, 2005), citados por Pereira (2015, p. 15). Cada vez mais as informações veiculadas através dos meios de comunicação social chamam a atenção para a importância da amamentação. No entanto, a promoção comercial desenvolvida pela indústria e empresas do setor podem diminuir a promoção do aleitamento materno, ao oferecerem amostras às mães nas maternidades, o que pode promover o abandono progressivo do aleitamento materno. Segundo Andrezza et al (2013) os bicos de qualquer natureza, quando utilizados por um determinado período, podem causar o fenómeno denominado de confusão de bicos, acabando por levar ao desmame precoce. Um estudo desenvolvido por França et al (2008) referem que o uso da chupeta é um dos determinantes principais que levam as mães a interromper precocemente o aleitamento. O uso da chupeta, referido desde o período neolítico (Castilho e Rocha, 2009), temática controversa, merece a atenção dos vários profissionais de saúde, e é considerado como um problema de Saúde Pública. Pereira (2015) no estudo que desenvolveu concluiu que as crianças que usaram chupeta apresentaram mais alterações na fala, na postura, mobilidade da língua e na mordida comparativamente com as que não a utilizaram. Galvão (2006, p. 25), ao citar a OMS e a UNICEF (1995), afirma que "as práticas adoptadas nos serviços de saúde podem ter um efeito importante sobre a amamentação. Práticas desfavoráveis interferem com a amamentação e contribuem para a disseminação do aleitamento artificial. Boas práticas apoiam o aleitamento materno e favorecem que as mães amamentem com sucesso e continuem a amamentar por longo tempo". Torna-se igualmente importante que as orientações fornecidas pelos profissionais de saúde não sejam diferentes, ambíguas ou contraditórias, pois pode aumentar a ansiedade e angústia das mães. Neste sentido, importa saber: o que sabem as mães que amamentam ou amamentaram sobre a influência do uso da chupeta no processo da amamentação e no desenvolvimento da criança? O que levou as mães que amamentam ou amamentaram a decidir colocar ou não chupeta aos filhos?

Enquadramento: Devido à elevada prevalência de abandono precoce da amamentação, diversas instituições (e.g., OMS, UNICEF) têm-se preocupado em proteger, promover e apoiar o aleitamento materno um pouco por todo o mundo, defendendo a sua exclusividade durante os primeiros seis meses de vida do bebé, complementado a partir dessa idade pela introdução de alimentos e mantido até aos 2 anos de idade ou mais, se esse for o desejo da mãe. Objetivos: Avaliar os conhecimentos das mães sobre a amamentação; identificar as dificuldades vivenciadas pelas mães em relação à amamentação; analisar a relação entre as variáveis sociodemográficas e obstétricas das mães e os seus conhecimentos e dificuldades sobre a amamentação. Metodologia: Estudo quantitativo, descritivo, analítico, correlacional e de corte transversal, conduzido numa amostra não probabilística de 100 mães de recém-nascidos e/ou lactentes até 1 ano de vida, internadas no serviço de obstetrícia, neonatologia, pediatria e urgência de uma Unidade Local de Saúde do Norte do País. As inquiridas tinham idade mínima de 16 e máxima de 43 anos (M=30,77; Dp=6,356). Foi utilizado um questionário de caraterização sociodemográfica e um questionário de autorrelato da vivência das mães sobre a amamentação, desenvolvido por Sousa (2014). Resultados: Os principais resultados mostraram que 50% das mães consideram possuir bons conhecimentos relativos à amamentação, porém, apenas 39% foram classificadas com bons conhecimentos, enquanto 52% revelaram dificuldades elevadas. Os conhecimentos foram avaliados tendo por base a sinalização correta da importância da amamentação na primeira hora de vida do bebé por 93% das mães, exclusiva até aos 6 meses (28%), a composição do leite materno e composição imunológica 93%, a maioria das mães considerou saber identificar os sinais da pega correta. Relativamente ao horário da amamentação, 62% ainda considera correto amamentar de três em três horas e 14% defende que o bebé deve mamar 10 minutos em cada mama. Os conhecimentos relacionaram-se significativamente com as mães com ensino superior (x2=17,828; p=0,00) e nas que se encontram a amamentar atualmente (UMW=278,000; p=0,01). As dificuldades mais prevalentes associaram-se às fissuras (56,4%), ingurgitamento mamário (38,5%), mastite (3,8%), dor (40%) e dificuldade na pega (60%), tendo-se constatado diferenças estatisticamente significativas associadas ao ingurgitamento mamário, à mastite e abcesso mamário. Exerce influência nas dificuldades das mães, ter sido informada pelo obstetra (UMW=324,000; p=0,02) e não ter expectativas na primeira amamentação (UMW=521,500; p=0,01). Conclusão: O estudo revela bons conhecimentos globais mas dificuldades elevadas, sendo estas as comumente referenciadas noutros estudos. Face a isto, mantem-se necessário apoiar nas dificuldades vividas durante a amamentação, adequando as estratégias de promoção, proteção e apoio ao AM, para que os resultados possam ser bem-sucedidos.

The vitamins A and E are recognizably important in the initial stages of life and the newborn depends on nutritional adequacy of breast milk to meet their needs. These vitamins share routes of transport to the tissues and antagonistic effects have been observed in animals after supplementation with vitamin A. This study aimed to verify the effect of maternal supplementation with vitamin A megadose (200,000 UI) in the immediate post-partum on the concentration of alpha-tocopherol in colostrum. Healthy parturient women attended at a public maternity natalensis were recruited for the study and divided into two groups: control (n = 37) and supplemented (n = 36). Blood samples of colostrum and milk were collected until 12 hours after delivery. The women of the supplemented group was administered a retynil palmitate capsule and 24 hours after the first collection was obtained the 2nd sample of colostrum in two groups for analysis of retinol and alpha-tocopherol in milk. The mean retinol concentration of 50,7 ± 14,4 μg/dL (Mean ± standard deviation) and alpha-tocopherol of 1217.4 ± 959 mg/dL in the serum indicate the nutritional status biochemical appropriate. Supplementation with retynil palmitate resulted in increase not only retinol levels in the colostrum of the supplemented group (p = 0.002), but also the concentration of alpha-tocopherol (p = 0.04), changing from 1456.6 ± 1095.8 mg/dL to 1804.3 ± 1432.0 mg/dL (milk 0 and 24 respectively) compared to values in the control group, 984.6 ± 750.0 mg/dL and 1175.0 ± 730.8 mg/dL. The women had different responses to supplementation, influenced by baseline levels of retinol in colostrum. Those with previous by low levels of retinol in colostrum (<60 mg/dL) had increased the concentration of alpha-tocopherol in milk, whereas those with adequate levels (> 60 mg/dL), showed a reduction after supplementation. Supplementation with retinol palmitate is an important intervention in situations of high risk for vitamin A deficiency, when considering the need to maternal supplementation, since the excess vitamin can offer unfavorable interactions between nutrients essential for the mother-child group

Vitamin A is important in many essential body processes and its deficiency results in serious consequences for human health. Breast milk is the only source of this vitamin for children that are exclusively breastfed. Analysis of vitamin A in mother s milk is important because its concentration is related to maternal vitamin A status and to its ingestion by the mother during pregnancy. The aim of the present study was to assess the effect of maternal supplementation with retynil palmitate on the concentration of colostrum retinol under fasting and postprandial conditions. A total of 149 nursing mothers were recruited at the Januário Cicco Maternity School (Natal, Brazil) and allocated to two groups: Comparison (n = 69) and Test (n = 80). Blood and colostrum (in fasting and postprandial conditions) samples were collected up to 24hs after delivery. Serum retinol and colostrum levels were analyzed by high-performance liquid chromatography. The serum retinol level of 41.6 ± 12.7μg/dL (mean ± standard deviation) indicates adequate biochemical nutritional status. Colostrum retinol level was not influenced by serum retinol levels under any of the conditions established. In the colostrum, the retinol concentration in the unsupplemented test group was 67.3 ± 37.7 μg/dL under fasting and 80.3 ± 35.1 μg/dL under postprandial conditions (p<0.05), showing an increase of 19.3%. In the supplemented test group the values were 102.6 ± 57.3 μg/dL and 133.4 ± 78.3 μg/dL under fasting and postprandial, respectively (p<0.05), representing an increase of 30%. Considering that under fasting conditions most of the vitamin A transported to the milk originates in the retinol binding protein (RBP), the postprandial increase in colostrum retinol suggests a different transport mechanism of retinol to maternal milk from that performed by RBP. This situation becomes more evident under supplementation conditions.

Vitamins A and E are essential nutrients in many biological processes, so that their adequate supply to the neonate is crucial. However, the bioavailability of vitamins may be limited by factors such as maternal nutritional status and the interaction between nutrients. This study aimed to investigate the effect of biochemical nutritional status of retinol and alpha-tocopherol levels in serum and colostrum. The study included 103 healthy puerperal women treated at the reference state maternity hospital (Natal-RN). Colostrum and serum samples were collected fasting in the immediate postpartum period and the analysis of retinol and alpha-tocopherol were determined by high-performance liquid chromatography. Specific cutoff points were adopted to characterize the biochemical status of vitamins A and E. For the total group of lactanting women the average concentration of retinol in serum (1.49 ± 0.4 μmol/L-1) and colostrum (2.18 ± 0.8 μmol/L-1), as well as alpha-tocopherol in serum (26.4 ± 8.0 μmol/L-1) and colostrum (26.1 ± 12.8 μmol/L-1), indicated adequate biochemical state. However, when evaluating the individual, was found a high prevalence of deficient serum (15%) and colostrum retinol (50%), and also alphatocopherol in serum (16%) and colostrum (61%). In women with serum retinol ≥ 1.05 μmol/L-1, found an inverse correlation between serum retinol and alpha-tocopherol in colostrum (p = 0.008, r = -0.28). This association was not observed in women with serum retinol <1.05 μmol/L-1. This situation demonstrates for the first time in humans that high physiological levels of serum retinol, without supplementation, can negatively influence the transfer of alpha-tocopherol in breast milk. Although the diagnosis of satisfactory nutritional status lactanting women showed high risk of subclinical deficiency of vitamins A and E from measurements made in the colostrum

Micronutrient deficiencies affect individuals mainly in developing countries, where vitamin A deficiency is a public health problem worldwide more worrying, especially in groups with increased physiological needs such as children and women of reproductive age. Vitamin A is supplied to the body through diet and has an important role in the visual process, cell differentiation, maintenance of epithelial tissue, reproductive and resistance to infection. The literature has demonstrated the relationship between vitamin A and diabetes, including gestational, leading to a risk to both mother and child. Gestational diabetes is any decrease in glucose tolerance of variable magnitude diagnosed each the first time during pregnancy, and may or may not persist after delivery. Insulin resistance during pregnancy is associated with placental hormones, as well as excess fat. Studies have shown that retinol transport protein produced in adipose tissue in high concentrations, this would be associated with resistance by interfering with insulin signaling. Therefore, this study aimed to evaluate the concentration of retinol in serum and colostrum from healthy and diabetic mothers in the immediate postpartum period. One hundred and nine parturient women were recruited, representing seventy-three healthy and thirty-six diabetic. Retinol was extracted and subsequently analyzed by High Performance Liquid Chromatography. Among the results highlights the mothers with gestational diabetes were older than mothers healthy, had more children and a higher prevalence of cases of cesarean section. Fetal macrosomia was present in 1.4% of healthy parturient women and in 22.2% of diabetic mothers. The maternal serum retinol showed an average of 39.7 ± 12.5 mg/dL for healthy parturients 35.12 ± 15 mg/dL for diabetic and showed no statistical difference. It was observed that in the group of diabetic had 17% vitamin A deficiency, whereas in the healthy group, only 4% of the women were deficentes. Colostrum, the concentration of retinol in healthy was 131.3 ± 56.2 mg/dL and 125.3 ± 41.9 mg/dL in diabetic did not differ statistically. This concentration of retinol found in colostrum provides approximately 656.5 mg/day for infants born to healthy mothers and 626.5 mg/day for infants of diabetic mothers, based on a daily consumption of 500 mL of breast milk and need Vitamin A 400 mg/day, thus reaching the requirement of the infant. The diabetic mothers showed significant risk factors and complications related to gestational diabetes. Although no 11 difference was found in serum retinol concentration and colostrum among women with and without gestational diabetes, the individual analysis shows that parturients women with diabetes are 4.9 times more likely to develop vitamin A deficiency than healthy parturients. However, the supply of vitamin A to the newborn was not committed in the presence of gestational diabetes

The Vitamin E consists of eight chemically homologous forms, designated alpha, beta, gamma and delta tocopherols and tocotrienols. Biologically, the alpha-tocopherol (α-TOH) is the most important. Commercially, are found two types of α-TOH a natural (RRR-alpha-tocopherol) and another synthetic (all-rac-alpha-tocopherol). Both forms are absorbed in the intestine, the liver is a preference in favor of forms 2R, due to transfer protein α-TOH. It has higher affinity to these stereoisomers. Newborns are considered high risk for vitamin E deficiency, mainly premature, these have breast milk as a food source for maintenance of serum α-TOH. Clinical signs such as thrombocytosis, hemolytic anemia, retrolental fibroplasia, intraventricular hemorrhage, bronchopulmonary dysplasia and spinocerebellar degeneration can be found in case of a low intake of α-TOH. Thus, maternal supplementation on postpartum with α-TOH can be an efficient way to increase levels of vitamin E in breast milk and thus the consequently increase the supply of micronutrient for the newborn. However, most studies with vitamin E supplementation have been conducted in animals and little is known about the effect of maternal supplementation in humans, as well as on its efficiency to increase levels of α-TOH in human milk, depending on the shape natural or synthetic. The study included 109 women, divided into three groups: control without supplementation (GC) (n=36), supplemented with natural capsule (GNAT) (n=40) and the synthetic capsule (GSINT) (n=33). Blood samples were collected for determination of maternal nutritional status, and colostrums at initial contact and after 24 hours post-supplementation. Analyses were performed by High Performance Liquid Chromatography. Values of α-TOH in serum below 499.6mg/dL were considered deficient. We used the Kruskal-Wallis test and Tukey test to confirm the increase of alpha-tocopherol in milk and efficiency of administered capsules. Daily consumption of α-TOH was based on daily intake of 500 mL of colostrum by the newborn and compared with the nutritional requirement for children from 0 to 6 months of age, 4 mg / day. The mothers had mean concentration of serum α-TOH in 1016 ± 52, 1236 ± 51 and 1083 ± 61 mg / dL, in CG, GNAT and GSINT respectively. There were no women with deficiiency. The GC did not change the concentrations of α-TOH in colostrum. While women supplemented with natural and synthetic forms increased concentrations of α-TOH colostrum in 57.6% and 39%, respectively. By comparing supplemented groups, it was observed a significant difference (p=0.04), the natural capsule more efficient than the synthetic, approximately 49.6%. Individually, 21.1% of the women provided below 4mg/day of α-TOH, after supplementation for this index declined4.1%. Thus, maternal supplementation postpartum raised the levels of alpha-tocopherol in colostrum, and increased efficiency was observed with the natural form
