Background: Probiotics are used for the prevention of necrotizing enterocolitis (NEC) because of their positive effects on intestinal motor function, modulation of inflammatory response, and mucosal barrier function.
OBJETIVOS: comparar as prevalências de sobrepeso e obesidade em um grupo de pré-escolares, escolares e adolescentes de diferentes condições socioeconômicas na cidade do Recife. MÉTODOS: estudo do tipo transversal envolvendo uma amostra de 1616 crianças e adolescentes, escolhida por conveniência. Os indicadores nutricionais foram definidos conforme as recomendações do National Center of Health Statistics 2000, sendo considerado sobrepeso o índice de massa corporal igual ou superior ao percentil 85 e inferior ao percentil 95 e obesidade, o índice de massa corporal igual ou superior ao percentil 95. RESULTADOS: foi identificado sobrepeso em 234 (14,5%) indivíduos e obesidade, em 134 (8,3%). A prevalência de sobrepeso foi maior nos pré-escolares (22,2%), observando-se redução progressiva da freqüência nas faixas etárias de escolar (12,9%) e adolescente (10,8%). Constatou-se fato idêntico quanto à obesidade, detectada em 13,8% dos pré-escolares, 8,2% dos escolares e 4,9% dos adolescentes. O sobrepeso e a obesidade foram mais observados entre crianças e adolescentes de melhor condição socioeconômica. CONCLUSÕES: as prevalências de sobrepeso e obesidade diminuíram à medida que ocorreu aumento da faixa etária. Entre os pré-escolares observou-se prevalência de sobrepeso semelhante, independente das condições socioeconômicas. A prevalência da obesidade foi maior entre escolares de boas condições socioeconômicas e adolescentes de baixa condição socioeconômica.
BackgroundTo identify markers for earlier diagnosis of severe pneumonia, we assess the correlation between serum cytokine profile of children with different pneumonia severity.MethodsIn 25 hospitalized children, 7 with mild pneumonia and 18 with severe pneumonia, the serum concentration of 11 cytokines in three sampling times were dosed. Statistical analysis included parametric and non-parametric tests, Pearson correlation and ROC curve for cut-off definition of cytokines.ResultsAt admission, IL-6 serum levels were high in mild or severe pneumonia, and was associated to vomiting (P = 0.019) in both groups; and also to dyspnea (P = 0.012) and white blood cell count (P = 0.045) in patients with severe pneumonia. IL-10 levels were also high in patients with pneumonia and were associated to lymphocytosis (P = 0.025). The ROC curve of the IL-6:IL-10 serum levels ratio discriminated severe pneumonia cases at admission, and persistence of infection in the third day of antibiotic therapy, with positive predictive values of 93% and 89%, respectively.ConclusionsThe balance between IL-6 and IL-10 serum levels showed to be a more discriminative marker for severity definition and evaluation of recovery in patients with pneumonia.Electronic supplementary materialThe online version of this article (doi:10.1186/s12890-016-0324-z) contains supplementary material, which is available to authorized users.
OBJETIVO: identificar o estado nutricional, função mastigatória, aeração nasal, dados sobre o sono, olfato e paladar de crianças respiradoras orais e compará-las com um grupo de crianças respiradoras nasais. MÉTODOS: avaliou-se estado nutricional, modo respiratório e mastigação de 77 crianças respiradoras orais e 154 respiradoras nasais entre seis e dez anos. RESULTADOS: os respiradores orais apresentaram alterações no padrão mastigatório, quando comparados aos respiradores nasais, porém não houve diferença estatisticamente significante em relação ao estado nutricional. CONCLUSÃO: em crianças respiradoras orais houve maior alteração no sono, diminuição da ingestão de carboidratos e aumento da ingestão de lipídeos, porém não foram encontrados dados consistentes que apontem a associação entre a respiração oral e o estado nutricional.
Food allergy is an immunologically mediated adverse reaction to food protein. Cow's milk protein allergy (CMPA) is the most frequent type and is the one that is most difficult to diagnose. This study had the objective of analyzing the accuracy of hypersensitivity and specific IgE skin tests among children with CMPA and predominantly gastrointestinal clinical manifestations. The participants in this study were 192 children aged one and five (median of 2 yr). Among these, 122 underwent open oral challenge to the suspected food. After evaluating the sensitivity, specificity and positive and negative predictive values (respectively, PPV and NPV) of skin and specific IgE tests in relation to the gold standard (open oral challenge); all the children underwent the skin prick test (SPT), specific IgE test and atopy patch test (APT) for cow's milk, eggs, wheat and peanuts and the open oral challenge for the food to which the child was sensitive or had suspected sensitivity. Presence of food allergy was confirmed for 50 children (40.9%). Among these cases, 44/50 (88%) were of allergy to cow's milk protein. Children who presented a positive response to an oral challenge to cow's milk protein were considered to be cases, while the controls were children with negative response. Twenty-two of the 44 cases (50.0%) presented symptoms within the first 4 h after the challenge. The SPT presented 31.8% sensitivity, 90.3% specificity, 66.7% PPV and 68.4% NPV. The APT presented 25.0% sensitivity, 81.9% specificity, 45.8% PPV and 64.1% NPV. The specific IgE test presented, respectively, 20.5%, 88.9%, 52.9% and 64.6%. Despite the operational difficulty and the possible exposure risk, oral challenge is the best method for diagnosing CMPA, because of the low sensitivity and PPV of skin and specific IgE tests.
Many factors explain dysbiosis in chronic constipation (CC), such as a low-fiber diet. The objective of this study was to compare the fecal microbiota of constipated and nonconstipated children and their intake frequencies of food. Methods. This observational study included 79 children (M/F 43/36) aged six to 36 months divided into two groups: cases (39 constipated children) and controls (40 nonconstipated children). We used a structured form to collect demographic variables, conducted anthropometric assessment, and collected food intake frequency data. The fecal microbiota of the stool samples was analyzed by real-time polymerase chain reaction (PCR) using the fluorophore SYBR® Green. Results. Constipated children had a smaller concentration of Lactobacillus per milligram of stool (p = 0.015) than nonconstipated children, but the concentration of Bifidobacterium per milligram of stool (p = 0.323) and the intake of fruits, vegetables (p = 0.563), and junk food (p = 0.093) of the two groups did not differ. Constipated children consumed more dairy products (0.45 ± 0.8; p > 0.001), were more frequently delivered via caesarean section (69.2%), were weaned earlier (median: 120; 60Q1–240Q3), and had a family history of constipation (71.8%). Conclusions. Children with CC have a smaller concentration of Lactobacillus in their stools and consume more dairy products.
The questionnaire was translated and adapted according to all the proposed steps, with all equivalences adequately met. It is a valid tool to access the QoL of celiac children and adolescents in the translated language.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
