Avaliação nutricional de pacientes cirúrgicos com câncer gastrointestinal em uso de suplemento alimentar / Nutritional evaluation of surgical patients with gastrointestinal cancer using food supplements

Objetivo: Avaliar a nutrição de pacientes cirúrgicos com neoplasia no trato gastrointestinal em uso de suplemento alimentar. Método: Trata-se de uma revisão sistemática de literatura realizada nas bases de dados Google Scholar, PubMed, Scielo e Web of Science, no período de maio a junho de 2021, sem recorte temporal ou restrição de idioma, através dos descritores: "enteral nutrition e immunenutrition", "cancerpatients e gastriccancerpatients", "preoperative, perioperative e postoperative". Resultados: Foram selecionados 8 estudos, destes, a maioria identificou benefícios na utilização da suplementação em razão da diminuição de células TNF-a, do cortisol e da transferrina, diminuindo o tempo de internação e melhora no estado funcional dos participantes suplementados. Conclusão: Os achados foram positivos, no entanto, houve algumas limitações como a heterogeneidade em abordagens terapêuticas e perda de pacientes durante o estudo, apesar de apresentarem baixo risco de viés, ainda há a necessidade de mais estudos.(AU)

Objective: To evaluate the nutrition of surgical patients with neoplasia in the gastrointestinal tract using food supplements. Method: This is a systematic literature review carried out in Google Scholar, PubMed, Scielo and Web of Science databases, from May to June 2021, without time frame or language restriction, using the descriptors: "enteral nutrition and immunenutrition", "cancerpatients and gastriccancerpatients", "preoperative, perioperative and postoperative". Results: Eight studies were selected, most of which identified benefits in the use of supplementation due to the decrease in TNF-a cells, cortisol and transferrin, reducing the length of hospital stay and improving the functional status of supplemented participants. Conclusion: The findings were positive, however, there were some limitations such as heterogeneity in therapeutic approaches and loss of patients during the study, despite having a low risk of bias, there is still a need for further studies(AU)

Objetivo: Evaluar la nutrición de pacientes quirúrgicos con neoplasia en el tracto gastrointestinal utilizando suplementos alimenticios. Método: Se trata de una revisión sistemática de la literatura realizada en las bases de datos Google Scholar, PubMed, Scielo y Web of Science, de mayo a junio de 2021, sin franja horaria ni restricción de idioma, utilizando los descriptores: "nutrición enteral e inmunonutrición", "pacientes oncológicos y pacientes con cáncer gástrico", "preoperatorio, perioperatorio y postoperatorio". Resultados: Se seleccionaron ocho estudios, la mayoría de los cuales identificaron beneficios en el uso de la suplementación por la disminución de células TNF-a, cortisol y transferrina, reduciendo la estancia hospitalaria y mejorando el estado funcional de los participantes suplementados. Conclusión: Los hallazgos fueron positivos, sin embargo, hubo algunas limitaciones como la heterogeneidad en los enfoques terapéuticos y la pérdida de pacientes durante el estudio, a pesar de tener un bajo riesgo de sesgo, aún existe la necesidad de realizar más estudios(AU)

Association of single nucleotide polymorphisms in TNF-α (-308G/A and -238G/A) to dengue: Case-control and meta-analysis study.

Dengue is an acute viral disease whose clinical condition is related to the interaction of factors related to the Dengue virus (DENV), environment and the host, with the immunity of the human host contributing a substantial role in the pathogenesis of DENV infection. Studies have demonstrated that single nucleotide polymorphisms (SNPs) in the promoter regions of cytokine genes such as tumor necrosis factor (TNF-α) affect transcription and/or expression; and therefore, may influence the pathogenesis of infectious diseases, such as dengue. Consequently, the objective of this study was to assess through a case-control study whether there was an association between the presence of SNPs -308G/A and -238G/A in the TNF-α gene and 158 patients with dengue and 123 controls. No association was found between the SNPs and the dengue cases in the study population. We then performed a meta-analysis, retrieving data from case-control studies in the literature for the same polymorphisms. For SNP-308G/A, the GG genotype was associated with dengue fever (DF) risk (OR = 1.24, 1.00-1.53; p = 0.05; I2 = 0%), while the GA genotype (OR = 0.75, 0.60-0.93; p = 0.01; I2 = 0%) and allele A (OR = 0.75, 0.60-0.93; p = 0.01; I2 = 0%) were associated with protection. The genotype GG population in the Asian continent (OR = 1.81 [1.06, 3.09], p = 0.03, I2 = 0%) and American (OR = 1.29 [1.00, 1.65], p = 0.05, I2 = 0%) was also associated with protection in the comparison between the cases versus the control group. In each comparison, the dominant model AA + GA (p < 0.00001) conferred protection. For SNP-238G/A the GA genotype was associated with risk for dengue hemorrhagic fever (DHF; OR = 2.17, 1.28-3.67; p = 0.004; I2 = 0%)), and the dominant AA + GA model (p < 0.00001) was associated with protection in each comparison. In summary, our results did not associate SNPs in the TNF-α gene to dengue in the Brazilian northeast population. However, combined literature data suggested the effect of the GG and GA genotypes of the SNP-308G/A on risk and protection, respectively, in Asian and American populations.
