Effects of probiotic supplementation on the anthropometric nutritional status of patients with type 2 Diabetes mellitus: A systematic review and meta-analysis protocol.

Background: Diabetes mellitus (DM) is characterized by hyperglycemia due to insufficient insulin production or utilization. Previous studies have shown a relationship between the gut microbiota and DM, driving interest in probiotic supplementation to modulate the microbiota and glucose metabolism in patients with DM, although the exact mechanisms remain unclear. Probiotics can influence metabolic factors and improve the composition of the microbiota, possibly helping to reduce weight in patients with DM.

Effect of maternal diet on the frequency of micronuclei in pregnant women and newborns: A protocol for systematic review and meta-analysis.

Background: The effects of diet on maternal and child genetic levels have been previously reported. Diet-associated DNA damage, such as the presence of micronuclei (MN), may be related to an increased risk of developing chronic diseases, such as cancer. Such damage is particularly concerning during pregnancy as it can affect the newborn.

Zinc Status and Autism Spectrum Disorder in Children and Adolescents: A Systematic Review.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder, the prevalence of which has increased in children and adolescents over the years. Studies point to deficiency of trace elements as one of the factors involved in the etiology of the disorder, with zinc being one of the main trace elements investigated in individuals with ASD. The aim of this review is to summarize scientific evidence about the relationship between zinc status and ASD in children and adolescents.
