Consumption of a multi-deficient diet causes dynamic changes in the intestinal morphofunctional barrier, body composition and impaired physical development in post-weaning mice.

Few studies have focused on nutrient-deficient diets and associated pathobiological dynamics of body composition and intestinal barrier function. This study evaluated the impact of a nutrient-deficient diet on physical development and intestinal morphofunctional barrier in mice. C57BL/6 (21 days of age) mice were fed a Northeastern Brazil regional basic diet (RBD) or a control diet for 21 d. The animals were subjected to bioimpedance analysis, lactulose test, morphometric analysis and quantitative reverse transcription-PCR to evaluate tight junctions and intestinal transporters. RBD feeding significantly reduced weight (P < 0·05) from day 5, weight gain from day 3 and tail length from day 14. The intake of RBD reduced total body water, extracellular fluid, fat mass and fat-free mass from day 7 (P < 0·05). RBD induced changes in the jejunum, with an increase in the villus:crypt ratio on day 7, followed by reduction on days 14 and 21 (P < 0·05). Lactulose:mannitol ratio increased on day 14 (P < 0·05). Changes in intestinal barrier function on day 14 were associated with reductions in claudin-1 and occludin, and on day 21, there was a reduction in the levels of claudin-2 and occludin. SGLT-1 levels decreased on day 21. RBD compromises body composition and physical development with dynamic changes in intestinal barrier morphofunctional. RBD is associated with damage to intestinal permeability, reduced levels of claudin-1 and occludin transcripts and return of bowel function in a chronic period.

Alterações laboratoriais em gestantes e puérperas com diagnóstico confirmatório de COVID-19 / Laboratory test alterations in pregnant and puerperal women diagnosed with COVID-19

Objetivo: Analisar as alterações de exames laboratoriais de gestantes e puérperas com diagnóstico laboratorial de COVID-19 atendidas em uma maternidade de referência em Fortaleza/Ceará, no período de março a outubro de 2020. Métodos: Trata-se de um estudo retrospectivo, descritivo, com abordagem quantitativa, envolvendo análise de dados dos exames laboratoriais de pacientes com diagnóstico confirmatório para COVID-19 no período de março a outubro de 2020. Os dados foram coletados a partir dos resultados de exames obtidos nas plataformas institucionais, revisão de dados e evoluções do prontuário físico e eletrônico. Resultados: As pacientes apresentaram notória redução de hemoglobina e hematócrito, leucocitose com linfopenia e alteração de parâmetros bioquímicos de função hepática. Na amostra estudada, obteve-se um percentual de óbitos de 5%. Além disso, evidenciou-se alteração de marcadores de inflamação e coagulação, dados que corroboram com os estudos na área. Conclusão: As alterações específicas da COVID-19 foram detectadas nos dois grupos de pacientes, ressaltando-se a importância da realização de novos estudos com enfoque na população gestante e puérpera, pois as consequências da doença nessa população podem afetar diretamente o binômio mãe-bebê.

Objective: To analyze the changes in laboratory tests of pregnant women and postpartum women with a laboratory diagnosis of COVID-19 attended at a reference maternity hospital in Fortaleza / Ceará, from March to October 2020. Methods: This is a retrospective, descriptive study, with a quantitative approach, involving the analysis of data from laboratory tests of patients with a confirmatory diagnosis for COVID-19 in the period from March to October 2020. The data were collected from the results of tests obtained in the institutional platforms as well as data review and evolution physical and electronic medical records. Results: The patients showed a marked reduction in hemoglobin and hematocrit, leukocytosis with lymphopenia and alteration of biochemical parameters of liver function. In the sample studied, a percentage of deaths of 5% was obtained. In addition, changes in inflammation and coagulation markers were evidenced, data that corroborate with studies in the area. Conclusion: Specific changes in COVID-19 were detected in the two groups of patients, emphasizing the importance of conducting further studies focusing on the pregnant and postpartum population, as the consequences of the disease in this population can be applied directly in the mother-child binomial.
