ABSTRACT

Introdução: a qualidade da dieta de gestantes está associada a complicações na gestação, dentre as quais o Diabetes mellitus Gestacional. Conhecer o padrão alimentar dessa população, por métodos que avaliem a qualidade global da dieta é importante, pois permite o ajuste da ingestão alimentar, pode evitar distúrbios associados para mãe e filho e contribuir na definição de estratégias de intervenção. Objetivo: avaliar a qualidade da dieta de gestantes de alto risco, inclusive com Diabetes mellitus Gestacional, e a presença de fatores relacionados ao desenvolvimento da patologia. Metodologia: estudo transversal, conduzido em um hospital do Nordeste. Foram coletadas variáveis clínicas, socioeconômicas, demográficas, de estilo de vida, antropométricas e dietéticas. A qualidade da dieta foi avaliada pelo HEIP-B. Resultados: o Diabetes mellitus Gestacional foi a patologia mais comum na gestação (n = 31; 70,4%), seguida pela hipertensão (n = 27; 61,4%). As frequências de excesso de peso materno pré e gestacional foram expressivas, sobretudo nas grávidas com Diabetes mellitus Gestacional (93,6% e 96,7%, respectivamente). Nenhuma paciente consumia dieta de má qualidade e a proporção de dieta de boa qualidade e precisando de melhorias foi similar. Mas observou-se que a maioria das grávidas diabéticas consomem dieta de boa qualidade (p = 0,046). Discussão: os percentuais de hipertensão e excesso de peso podem ter levado ao desenvolvimento de Diabetes mellitus Gestacional pelas gestantes, pois são fatores de risco para a doença. A qualidade da dieta acompanha a preocupante tendência mostrada por outros estudos. O maior consumo de dieta de boa qualidade por gestantes diabéticas é animador, tendo em vista a importância da dieta no tratamento da patologia. Conclusão: gestantes diabéticas parecem se preocupar com a alimentação e, em sua maioria, consomem dieta de boa qualidade. Mas o HEIP-B mostrou alto percentual de gestantes adeptas de dietas precisando de melhorias e que não seguem plano alimentar orientado. Não apenas a qualidade da dieta, mas também as expressivas freqüências de hipertensão e excesso de peso são preocupantes e falam a favor da alta prevalência de Diabetes mellitus Gestacional observada. Estes resultados reforçam a necessidade de melhoria na qualidade da alimentação desse público, fazendo-se necessário incentivar práticas alimentares saudáveis, além do acompanhamento pré-natal para o diagnóstico das patologias e sua intervenção precoce (AU)


Introduction: the quality of the diet of pregnant women is associated with complications during pregnancy, such as Gestational Diabetes Mellitus. Knowing the dietary pattern of this population, by methods that evaluate the overall quality of the diet is important, since it allows the adjustment of food intake, can avoid associated disorders for mother and child and contribute to the definition of intervention strategies. Objective: to evaluate the quality of the diet of high-risk pregnant women, including Gestational Diabetes Mellitus, and the presence of factors related to the development of the pathology. Methodology: a cross-sectional study conducted at a hospital in the Northeast. Clinical, socioeconomic, demographic, lifestyle, anthropometric and dietary variables were collected. The quality of the diet was evaluated by HEIP-B. Results: Gestational Diabetes mellitus was the most common pathology in pregnancy (n = 31, 70.4%), followed by hypertension (n = 27, 61.4%). The frequencies of pre and gestational maternal overweight were significant, especially in pregnant women with Gestational Diabetes mellitus (93.6% and 96.7%, respectively). No patient consumed poor diet and the proportion of good quality diet and needing improvement was similar. But it was observed that the majority of diabetic pregnant women consume a good quality diet (p = 0.046). Discussion: Percentages of hypertension and overweight may have led to the development of Gestational Diabetes Mellitus by pregnant women, as they are risk factors for the disease. The quality of the diet accompanies the worrying trend shown by other studies. The higher consumption of good quality diet by pregnant diabetics is encouraging, considering the importance of diet in the treatment of pathology. Conclusion: Diabetic pregnant women seem to worry about eating and, for the most part, consume good quality diet. But HEIP-B showed a high percentage of pregnant women who were diets in need of improvement and did not follow a food oriented plan. Not only the quality of the diet, but also the expressive frequencies of hypertension and overweight are worrisome and speak in favor of the high prevalence of observed Gestational Diabetes Mellitus. These results reinforce the need to improve the quality of food for this public, making it necessary to encourage healthy eating practices, as well as prenatal care to diagnose pathologies and their early intervention (AU)

ABSTRACT

The aim of the study was to compare the innate immune system of severely malnourished children admitted to the Instituto de Medicina Integral Professor Fernando Figueira and treated according to the protocol of the World Health Organization (WHO) at admission and discharge. An experimental study was conducted with 20 children under two years of age. Ten of them had severe malnutrition and ten were a control group. The malnourished group consisted of hospitalized infants and it was submitted to WHO’s protocol. Children with HIV and re-admitted during the study period were excluded. A blood sample was taken at admission and at discharge. Later, an analysis of blood leukocytes, adherence index, phagocytic capacity, production of free radicals superoxide and nitric oxide was performed. Patients with severe malnutrition at hospital discharge showed improved phagocytic function, release of oxygen radicals and reduction of the number of lymphocytes when compared to the time of admission. When compared to the control group, patients at hospital discharge had lower lymphocyte values and lower production of free radicals. Thus, it can be concluded that the duration of hospitalization was insufficient to restore cell-mediated immunity and microbicide activity (AU)


El objetivo del estudio fue comparar el sistema inmune innato de niños con malnutrición grave ingresados en el Instituto de Medicina Integral Professor Fernando Figueira, tratados de acuerdo con el protocolo de la Organización Mundial de la Salud (OMS), al ingreso y al alta hospitalaria. Se llevó a cabo un estudio experimental con 20 niños menores de dos años de edad, 10 con malnutrición grave y 10 niños del grupo de control. El grupo de malnutridos se compuso de lactantes hospitalizados y sometidos al protocolo de la OMS. Se excluyeron los niños afectados por el HIV y los readmitidos durante el período del estudio. Se recogió una muestra de sangre al ingreso y otra al alta, y posterioriormente se realizó el análisis del perfil leucocitario, y el índice de adherencia, la capacidad fagocítica y la producción de los radicales libres superóxido y óxido nítrico. Los pacientes con malnutrición grave en el alta hospitalaria mostraron mejoría de la función fagocítica, la liberación de radicales oxidantes y la reducción del número de linfocitos en comparación con el ingreso hospitalario. En comparación con el grupo de control, los pacientes en el alta hospitalario presentaron valores más bajos de linfocitos y de producción de radicales libres. Por lo tanto, se puede concluir que el tiempo de hospitalización fue insuficiente para restablecer la inmunidad mediada por células, así como para restaurar la actividad microbicida (AU)

ABSTRACT

Nos períodos críticos de desenvolvimento do organismo, estímulos ambientais como o exercício físico e a dieta podem influenciar o fluxo placentário e o crescimento somático fetal. O objetivo do presente estudo foi avaliar as repercussões do treinamento físico e da desnutrição durante a gestação sobre os eixos cranianos de ratos neonatos. Ratos machos Wistar foram divididos de acordo com a manipulação de suas mães: não treinados controle (Cf, n = 25), treinados (Tf, n = 25), não treinados e desnutridos (Df, n = 25), treinados e desnutridos (TDf, n = 25). Mães treinadas (T e TD) foram submetidas a oito semanas de treinamento físico moderado antes e durante a gestação (60min/dia, cinco dias/sem a 65 por cento do VO2max). Mães desnutridas (D e TD) receberam dieta hipoproteica durante a gestação (8 por cento caseína) enquanto as nutridas (C e T) receberam dieta normoproteica (17 por cento caseína). No primeiro dia pós-natal foi verificado número de filhotes nascidos por ninhada, peso da ninhada e peso ao nascer, eixo látero-lateral do crânio (ELLC) e anteroposterior do crânio (EAPC), eixo longitudinal do corpo (EL) e comprimento da cauda (CC) de cada neonato. No terceito dia pós-parto, os encéfalos foram extraídos e pesados. Durante a gestação, as fêmeas dos grupos T e D apresentaram menor ganho de peso em comparação ao grupo C na terceira semana (C = 34,4 ± 1,3; T = 30,7 ± 0,60; D = 25,8 ± 0,78; TD = 29,9 ± 0,83). Os grupos desnutridos apresentaram menor peso ao nascer em relação aos seus respectivos controles (Cf = 6,3 ± 0,1; Tf = 6,3 ± 0,1; Df = 4,7 ± 0,07; TDf = 5,0 ± 0,06). O grupo Df apresentou as medidas do ELLC (Cf = 9,8 ± 0,06; Tf = 9,8 ± 0,05; Df = 9,2 ± 0,04; TDf = 9,6 ± 0,13) e EAPC (Cf = 18,1 ± 0,1; Tf = 18,2 ± 0,1; Df = 17,5 ± 0,1; TDf = 18,0 ± 0,2) menores comparadas aos filhotes controles. Com base nos resultados, pode-se concluir que a desnutrição no período fetal alterou o desenvolvimento somático enquanto o treinamento físico influenciou positiv...


In critical periods of body development, environmental stimuli such as physical exercise and diet may influence on placental flow and fetal somatic growth. The aim of this study was to evaluate the effects of physical training and malnutrition during pregnancy on the skull axis of newborn rats. Male Wistar rats were divided according to manipulation of their mothers: untrained control (Cf, n = 25), trained (Tf, n = 25), untrained and malnourished (Mf, n = 25), trained and malnourished (TMf, n = 25). Trained mothers (T and TM) were submitted to 8 weeks of moderate physical training before and during pregnancy (60min/day, 5 days/wk to 65 percent of VO2max). Malnourished mothers (M and TM) received a low protein diet during pregnancy (8 percent casein) while the nourished (C and T) were fed with normal diet (17 percent casein). On the 1st postnatal day, the number of pups born per litter, litter weight and birth weight, latero-lateral axis of skull (LLAS) and antero-posterior axis of skull (APAS), longitudinal axis of the body (LA) and length of tail (LT) of each neonate were verified. On the 3rd day after delivery, the brains were extracted and weighed. During pregnancy, the females of the T and M groups showed lower weight gain compared with group C at 3rd week (C = 34.4 ± 1.3, T = 30.7 ± 0.60, M = 25.8 ± 0.78, TM = 29.9 ± 0.83). The malnourished group had lower birth weight in relation to their respective controls (Cf = 6.3 ± 0.1, Tf = 6.3 ± 0.1, Mf = 4.7 ± 0.07; TMf = 5.0 ± 0.06). Group Mf presented measures of LLAS (Cf = 9.8 ± 0.06, Tf = 9.8 ± 0.05, Mf = 9.2 ± 0.04; TMf = 9.6 ± 0.13) and EAPC (Cf = 18.1 ± 0.1, Tf = 18.2 ± 0.1, Mf = 17.5 ± 0.1, TMf = 18.0 ± 0.2) lower compared to controls. Based on the results, it can be concluded that malnutrition during fetal period changed somatic development, while physical training positively influenced on the skull axis of the concepts.

ABSTRACT

OBJETIVO: Avaliar se a desnutrição no período neonatal produz prejuízos no recrutamento celular para o pulmão e na atividade oxidante-antioxidante de macrófagos alveolares em ratos adultos endotoxêmicos. MÉTODOS: Ratos machos Wistar (n=48) foram alimentados por mães cuja dieta, durante a lactação, continha 23 por cento de proteína no grupo nutrido e 8 por cento no grupo desnutrido. Após o desmame todos os animais foram recuperados com dieta normoprotéica. Entre 90 e 120 dias, a metade de cada grupo foi submetida à endotoxemia por meio da administração por via intraperitonial (v.i) de lipopolissacarídio na dose de 1mg/kg de peso corporal. Após 24 horas desse procedimento coletou-se o sangue para contagem total e diferencial de leucócitos e para a dosagem de óxido nítrico. Além do sangue coletou-se também o lavado broncoalveolar para contagem total e diferencial de leucócitos e, a partir de macrófagos isolados deste lavado, foram realizadas as dosagens de superóxido, óxido nítrico e superóxido dismutase. RESULTADOS: A desnutrição acarretou um déficit ponderal que persistiu até a idade adulta, além disso, reduziu a contagem total de leucócitos sangüíneos e o número de neutrófilos após o estímulo com lipopolissacarídio. A atividade oxidante-antioxidante foi alterada havendo diminuição da produção de superóxido, óxido nítrico e superóxido dismutase antes e após a indução da endotoxemia. CONCLUSÃO: Esses resultados sugerem que a desnutrição neonatal, mesmo após a recuperação nutricional, compromete o recrutamento celular para o pulmão e a atividade oxidante-antioxidante dos macrófagos alveolares em ratos adultos. A endotoxemia contribui para evidenciar essas seqüelas da resposta do hospedeiro frente a este modelo de desnutrição.


OBJECTIVE: The objective of this study was to assess if neonatal malnutrition impairs cell recruitment to the lungs and the oxidant-antioxidant activity of alveolar macrophages in adult endotoxemic rats. METHODS: Male Wistar rats (n=48) were divided into two groups and suckled by dams fed experimental diets containing a normal protein content of 23 percent (nourished group) and a low protein content of 8 percent (undernourished group) during lactation. After weaning, all animals received a normal protein diet. Between 90 and 120 days, half of each group was submitted to endotoxemia by intraperitoneal administration of 1mg/kg of body weight of lipopolysaccharide. Blood was collected 24 hours after this procedure for total and differential leukocyte count and measurement of nitric oxide. Bronchoalveolar lavage was also done to determine total and differential leukocyte count and measure superoxide, nitric oxide and superoxide dismutase in the macrophages isolated from this lavage. RESULTS: Malnourished animals remained underweight until adulthood. Furthermore, the following also decreased: total blood leukocyte count, number of neutrophils after lipopolysaccharide administration and production of superoxide, nitric oxide and superoxide dismutase before and after induced endotoxemia. CONCLUSION: These results suggest that neonatal malnutrition, even after nutritional recovery, compromises cell recruitment to lungs and the oxidant-antioxidant activity of alveolar macrophages of adult rats. Endotoxemia contributes to evidence these sequelae to the host response before this model of malnutrition.

ABSTRACT

OBJETIVO: Investigar os níveis de produção de SOD por monócitos periféricos em pacientes jovens portadores de esquistossomose hepatoesplênica submetidos à esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico. MÉTODO: Quatro grupos foram envolvidos na investigação: G1 - 12 portadores de esquistossomose hepatoesplênica (EHE) sem tratamento; G2 - 13 portadores de EHE que receberam tratamento clínico e se submeteram à operação para descompressão do sistema porta: esplenectomia e ligadura da veia gástrica esquerda (EHE/ELGE); G3 - 19 pacientes jovens similares a G2, mas que receberam também auto-implante de tecido esplênico no omento maior (EHE/ELGE/AI); e G4 - 15 indivíduos sem infecção pelo S. mansoni advindos da mesma área geográfica, apresentando as mesmas condições sócio-econômicas (GC). RESULTADOS: Os indivíduos normais (GC - sem esquistossomose) apresentam níveis de SOD significantemente menores que os portadores de EHE sem tratamento (p<0,01); e aqueles do grupo EHE/ELGE (p<0,05). Os níveis de SOD do grupo EHE/ELGE/AI são estatisticamente similares ao grupo GC (p>0,05). CONCLUSÃO: Os resultados corroboram a hipótese de que o tratamento clínico associado à esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico, em portadores jovens de esquistossomose hepatoesplênica, tendem a manter a resposta imune desses indivíduos.


BACKGROUND: Super oxide dismutase (SOD) is an enzyme that catalyzes the dismutation of super oxide radicals. It is important not only for protecting the human immune system against S. mansoni, as well as for producing competent response from the host against this parasite or other infectious agents. So, it has been investigated the production levels of SOD by peripheral monocytes from young carriers with hepatosplenic schistosomiasis mansoni who underwent splenectomy, left gastric vein ligature and spleen tissue autoimplantation. METHODS: Four groups were enrolled in the investigation: G1 - 12 carriers with hepatosplenic schistosomiasis mansoni without treatment (HSM); G2 - 13 HSM patients who received medical treatment and underwent surgery for relief of portal hypertension - splenectomy and left gastric vein ligature (HSM/SLGV); G3 - 19 young patients, similar to those of G3 who in addition received spleen morsels autoimplantation on the greater omentum (HSM/SLGV/AI); and G4 - 15 subjects from the same area with the same economical status without S. mansoni infection (Control group CG). RESULTS: The CG presented significantly lower levels of SOD as compared with the HSM patients (p<0.01) and those of G2 (HSM/SLGV) - (p<0.05). Levels of SOD from patients of group G3 (HSM/SLGV/AI) were similar to those of the control group (p>0.05). CONCLUSION: The results lend further support to the hypothesis that clinical treatment followed by splenectomy, left gastric vein ligature and spleen morsels autoimplantation in young patients, who were schistosomiasis mansoni carriers with hepatosplenic form, helps to maintain the immune response of these patients.

ABSTRACT

A endotoxemia está associada a uma ampla e inespecífica cascata de eventos. Isto resulta na secreção de uma variedade de potentes mediadores pró-inflamatórios e citocinas produzidos primariamente por macrófagos e monócitos ativados. Na desnutrição, a maioria dos mecanismos de defesa do organismo está prejudicada. Assim, a infecção é a maior causa de morbidade e mortalidade em indivíduos severamente desnutridos. O presente trabalho tem por objetivo revisar mecanismos patogênicos da endotoxemia na desnutrição precoce seguida de recuperação nutricional.

ABSTRACT

PURPOSE: To measure the levels of NO production by monocytes in patients with the hepatosplenic form of schistosomiasis mansoni who underwent splenectomy, ligature of the left gastric vein and auto implantation of spleen tissue in the major omentum. METHODS: Four groups of volunteers were enrolled in the investigation: G1 - 12 patients with S. mansoni infection in its hepatosplenic form without any kind of treatment (SMH); G2 - 13 SMH patients who underwent medical treatment and portal hypertension decompression splenectomy and ligature of the left gastric vein (SMH/SLGV); G3 - 19 patients similar to the later group, but additionally received auto implantation of spleen morsels in the major omentum (SMH/SLGV/AI); and G4 - 15 individuals with no S. mansoni infection coming from the same geographical area and presenting similar socio economical status (CG). Nitrite production by monocytes was determined by a standard Griess reaction adapted to microplates. The results were presented by mean ± SD for each group. Significant differences in NO production by monocytes were determined by Tukey-Kramer multicomparisons test. Probability values of 0.05 were considered significant. RESULTS: Patients from G1 (SMH) showed lower level of NO production by monocytes (5.28 ± 1.28µmol/ml). Patients from G2 (SMH/SLGV) showed similar results (6.67 ± 0.44µmol/ml - q = 2.681 p > 0.05). Individuals of G4 (CG) showed higher level of NO production by monocytes (8.19 ± 2.74µmol/ml). Patients from G3 (SMH/SGLV/AI) showed similar NO production by PBMC as compared to individuals of G4 (CG) - (7.41 ± 1.65µmol/ml - q = 1.615 p > 0.05). The volunteers from G4 (CG) and G3 (SMH/SLGV/AI) showed significantly greater levels of NO production by monocytes as compared to those from G1 (SMH) - (q = 5.837 p < 0.01, and q = 4.285 p < 0.05). CONCLUSION: Collectively, the results point to a restoration of NO normal production by monocytes in SH...


OBJETIVO: Mensurar os níveis de produção de ON por monócitos do sangue periférico (MSP) em portadores de esquistossomose na forma hepatoesplênica que tinham se submetido a esplenectomia, ligadura da veia gástrica esquerda e auto-implante de tecido esplênico no omento maior. MÉTODOS: Quatro grupos de voluntários foram envolvidos na investigação: G1 - 12 portadores de esquistossomose hepatoesplênica sem nenhuma forma de tratamento (EHE); G2 - 13 portadores de EHE que receberam tratamento clínico e se submeteram cirurgia para descompressão do sistema porta esplenectomia e ligadura da veia gástrica esquerda (EHE/ELGE); G3 - 19 pacientes similares ao do último grupo, mas que receberam também auto-implante de fragmentos de tecido esplênico no omento maior (EHE/ELGE/AI); e G4 - 15 indivíduos sem infecção pelo S. mansoni advindos da mesma área geográfica e apresentando as mesmas condições sócio-econômicas (GC). A produção de ON pelos MSP foi determinada pela reação padrão de Griess, adaptada para poços em microplaca. Os resultados foram expressos por suas médias ± DP para cada grupo. Diferenças significantes nas medias de produção de ON pelos MSP foram determinadas pelo teste de comparações múltiplas de Tukey-Kramer. Foram aceito os limites de significância de p < 0,05. RESULTADOS: Os pacientes portadores de EHE não tratados (G1) evidenciaram os níveis mais baixos de produção de ON pelos MSP (5,28 ± 1,28µmol/ml). Os pacientes do G2 (EHE/ELGE) evidenciaram resultados similares (6,67 ± 0,44µmol/ml - q = 2,681 p > 0.05). Os indivíduos do G4 (GC) evidenciaram os mais altos níveis de produção de ON pelos MSP (8,19 ± 2,74µmol/ml). Os pacientes do G3 (EHE/ELGE/AI) evidenciaram produção de ON produzido pelos MSP similares aos indivíduos do - G4 (GC) (7.41 ± 1.65µmol/ml - q = 1.615 p > 0.05). Os voluntários do G4 (GC) e os do G3 (EHE/ELGE/AI) evidenciaram de forma significante maiores níveis de produção de ON pelos MS...

Individuals of G4 (CG) showed higher level of NO production by monocytes (8.19 +/- 2.74 micromol/ml). Patients from G3 (SMH/SGLV/AI) showed similar NO production by PBMC as compared to individuals of G4 (CG) - (7.41 +/- 1.65 micromol/ml- q = 1.615 p > 0.05).

CONCLUSION: Collectively, the results point to a restoration of NO normal production by monocytes in SHM patients who underwent medical and surgical treatments, especially in those who had received auto implantation of spleen tissue in the major omentum after splenectomy and ligature of the left gastric vein. The data gives further support to the hypothesis that this additional procedure is important in the restoration of the immune response of these patients, since NO synthesis by the monocytes correlates with protective immunity against infection; thus, protecting them against overwhelming post splenectomy infection.
