RESUMO
OBJECTIVE: To perform a systematic review of randomized controlled trials, evaluating the effect of probiotics, prebiotics or symbiotics supplementation on glycemic and inflammatory control in children with Type 1 Diabetes Mellitus (T1DM). DATA SOURCE: The Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO) databases were searched. Randomized clinical trials of pediatric patients with DM1 using probiotics, prebiotics or symbiotics were included, regardless of year or language of publication. Studies that did not evaluate glycated hemoglobin (HbA1c) were excluded. Metabolic results (HbA1c, total insulin dose and C-peptide) and inflammatory control [interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ)] during probiotic supplementation or similar, related to modification of the intestinal microbiota, were analyzed. PROSPERO ID: CRD42022384485. DATA SYNTHESIS: Five studies were selected for a systematic review. Regarding metabolic markers, only one of the articles that analyzed HbA1c showed a significant decrease (p=0.03) in the intervention group. One study identified a reduction in the total dose of insulin and increased C-peptide levels. Regarding the evaluation of inflammatory parameters (IL-10, TNF-α, INF-γ), there were no statistical relevant modifications. CONCLUSIONS: Current data from the literature were not conclusive in identifying an improvement in glycemic control and did not observe changes in inflammatory parameters with the use of probiotics, prebiotics or symbiotics in pediatric patients with T1DM.

RESUMO Objetivo: Realizar uma revisão sistemática de ensaios clínicos randomizados controlados avaliando o efeito da suplementação de probióticos, prebióticos ou simbióticos no controle glicêmico e inflamatório em crianças com diabetes mellitus tipo 1 (DM1). Fontes de dados: As bases Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Scientific Electronic Library Online (SciELO) foram pesquisadas. Foram incluídos ensaios clínicos randomizados de pacientes pediátricos com DM1 em uso de probióticos, prebióticos ou simbióticos, independentemente de ano ou idioma de publicação. Foram excluídos os trabalhos que não avaliaram hemoglobina glicada (HbA1c). Os resultados metabólicos (HbA1c, dose de insulina total e peptídeo C) e o controle inflamatório [interleucina-10 — IL-10), fator de necrose tumoral-alfa (TNF-α) e interferon-gama (IFN-γ)] durante a suplementação de probióticos ou similares, relacionados à modificação da microbiota intestinal, foram analisados. ID PROSPERO: CRD42022384485. Síntese dos dados: Cinco estudos foram selecionados para revisão sistemática. Com relação aos marcadores metabólicos, apenas um dos artigos que analisaram a HbA1c apresentou diminuição significativa (p=0,03) no grupo intervenção. Um estudo identificou redução da dose total de insulina e aumento dos níveis de peptídeo C. Quanto à avaliação dos parâmetros inflamatórios (IL-10, TNF-α, INF-γ), não houve modificações de relevância estatística. Conclusões: Os dados atuais da literatura não foram conclusivos em identificar melhora no controle glicêmico e não observaram mudanças nos parâmetros inflamatórios com o uso de probióticos, prebióticos ou simbióticos em pacientes pediátricos com DM1.
RESUMO
ABSTRACT BACKGROUND AND OBJECTIVES: Some authors correlate incorrect head and neck postures during cell phone use with cervical pain. The objective, therefore, is to correlate the constant use of cell phones with discomfort in the cervical region and the repercussion on daily activities in college students. METHODS: Cross-sectional study carried out between July 2019 and March 2020 using the questionnaires "Smartphone Addiction Inventory Instrument", "Neck Disability Index" and "Young Spine Questionnaire", and also a questionnaire about demographic and socioeconomic data. The nutritional status of the participants was also evaluated and the degree of anteriorization of the head was measured in relation to the spinous process of the seventh cervical. RESULTS: The average age of the participants was 18.47±0.65 years. There was a significant statistical association between Smartphone dependence and cervical pain, and adolescents with Smartphone use dependency had the highest percentages of doctor visits for cervical pain. There was no association between smartphone dependence and absence from school or not playing sports due to pain in the spine; nutritional status; the angle of the neck and the father or mother having pain in the spine. Students with smartphone use dependency had the highest percentages of mild to moderate disability in the skills of daily activities. CONCLUSION: Dependence on cell phone use, in this study, is related to cervical pain and disability in the skills of daily activities.
RESUMO JUSTIFICATIVA E OBJETIVOS: Alguns autores correlacionam com dor cervical posturas de cabeça e pescoço durante o uso do celular consideradas incorretas. Objetivou-se, portanto, verificar a associação do uso constante de celular com desconforto na região cervical e repercussão nas atividades diárias em estudantes universitários. MÉTODOS: Estudo transversal realizado entre julho de 2019 e março de 2020 através da aplicação dos questionários Smartphone Addiction Inventory Instrument, Neck Disability Index e Young Spine Questionnaire, além de um questionário contendo dados demográficos e socioeconômicos. Foi avaliado, ainda, o estado nutricional dos participantes e mensurado o grau de anteriorização da cabeça em relação ao processo espinhoso da sétima vértebra cervical. RESULTADOS: A média etária dos participantes foi 18,47±0,65 anos. Houve associação estatística significativa entre o uso de celular com dor cervical. Os adolescentes com tempo prolongado de uso do celular foram os que apresentaram maior frequência de consulta médica por dor na região cervical. Não houve associação entre uso de celular e ausência na escola ou não praticar esporte devido a dor na coluna, o estado nutricional, o ângulo do pescoço e o fato de pai ou mãe ter dor na coluna. Os adolescentes com dependência de celular foram os que tiveram maior frequência de incapacidade leve a moderada nas habilidades das atividades diárias. CONCLUSÃO: A dependência do celular apresentou, neste estudo, uma relação com dores na coluna cervical e incapacidade nas habilidades das atividades diárias.

OBJECTIVE: To evaluate changes in peripheral immunological response (decrease in blood proinflammatory cytokines) and fecal microbiota (especially Bacteroidetes and Firmicutes) after administration of probiotics in children with celiac disease on a gluten-free diet. DATA SOURCE: The databases MEDLINE, LILACS, Springer and SciELO were used for this review, with the descriptors "celiac disease AND probiotics". At the end of the search, 168 articles were retrieved, four of which were included in the final qualitative synthesis, having as inclusion criteria randomized clinical trials and pediatric population (1-19 years) and, as exclusion criteria, interventions other than probiotics, studies with patients with other diseases associated with celiac disease, or patients who did not meet the diagnostic criteria. All elected studies were published until September 2020, without language restriction, with patients receiving strains of Bifidobacterium breve or B. longum and on a gluten-free diet. DATA SYNTHESIS: The studies show that the administration of probiotics along with a gluten-free diet, can approximate the fecal microbiota of celiac patients to typical conditions of healthy individuals, by restoring the abundance of some microbial communities that characterize the typical physiological condition. In addition, the administration of probiotics can reduce serum proinflammatory cytokines (mainly TNF-alpha). CONCLUSIONS: Despite the positive correlation between probiotics and fecal microbiota/serological markers in pediatric patients with celiac disease, we emphasize the need for future multicentric studies that should include a larger number of patients and a longer follow up period.

OBJECTIVE: Evaluate the effects of probiotics use, compared with placebo, in pediatric patients with non-alcoholic fatty liver disease (NAFLD), using laboratorial and ultrasonographic parameters as outcomes. METHODS: A systematic review of the literature was performed through MEDLINE and Lilacs databases. The articles selected were randomized controlled clinical trials published until November 2018, without any language restriction, dealing with pediatric patients with NAFLD. Patients were divided into 2 groups. One group received probiotic therapy and the other group, only received placebo. The primary outcome evaluated was the difference between the serum levels of alanine aminotransferase (ALT) before and after receiving probiotics or placebo. The secondary outcomes evaluated were the serum aspartate aminotransferase levels, body mass index, serum triglycerides, waist circumference and level of liver steatosis on the ultrasonography. RESULTS: A total of 46 articles were recovered, and 3 articles were included in the qualitative analysis, totaling 128 patients. Two trials revealed a significant decrease of alanine aminotransferase levels after treatment with probiotics (Lactobacillus rhamnosus for 8 weeks; Bifidobacterium+Lactobacillus for 12 weeks), when compared to the placebo. The other variables did not show a statistically significant difference between both groups. CONCLUSIONS: Probiotic therapy has contributed to the reduction of ALT serum levels in pediatric patients with nonalcoholic fatty liver disease, which is in line with results found by other authors in scientific literature. Regarding the secondary outcomes, the use of probiotics did not show benefits or damages compared to placebo.

RESUMO Objetivo: Avaliar os efeitos do uso de probióticos em comparação com placebo, em pacientes pediátricos portadores de doença hepática gordurosa não alcoólica (DHGNA), utilizando parâmetros laboratoriais e ultrassonográficos como desfecho. Métodos: Revisão sistemática da literatura por meio das bases de dados Sistema Online de Busca e Análise de Literatura Médica (MEDLINE) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs). Foram selecionados ensaios clínicos controlados randomizados publicados até novembro de 2018, sem restrição de língua, com pacientes pediátricos portadores de DHGNA, divididos em dois grupos. Um grupo foi submetido à terapia probiótica e outro grupo recebeu somente placebo. O desfecho primário avaliado foi a comparação dos níveis de alanina aminotransferase (ALT) ao início e no fim do seguimento entre os grupos probiótico e placebo. Os desfechos secundários avaliados foram os níveis de aspartato aminotransferase sérico, índice de massa corpórea, triglicerídeos totais séricos, circunferência abdominal e grau de esteatose hepática à ultrassonografia abdominal. Resultados: Foram recuperados 46 artigos, sendo três incluídos na análise qualitativa, totalizando 128 pacientes. Dois estudos demonstraram redução significativa dos níveis de ALT com o uso de probiótico (Lactobacillus rhamnosus, por oito semanas; Bifidobacterium+Lactobacillus, por 12 semanas), em comparação ao placebo. As demais variáveis avaliadas não evidenciaram diferença estatisticamente significante ente os dois grupos. Conclusões: O uso de probióticos representou redução nos níveis séricos de ALT na esteatose hepática na infância, indo ao encontro dos resultados obtidos por outros autores da literatura científica vigente. No que se refere às variáveis de desfecho secundário, não foi demonstrado benefício ou dano do tratamento de probióticos em relação ao placebo.
