Post Natal Microbial and Metabolite Transmission: The Path from Mother to Infant.

The entero-mammary pathway is a specialized route that selectively translocates bacteria to the newborn's gut, playing a crucial role in neonatal development. Previous studies report shared bacterial and archaeal taxa between human milk and neonatal intestine. However, the functional implications for neonatal development are not fully understood due to limited evidence.

Favipiravir and/or nitazoxanide: a randomized, double-blind, 2×2 design, placebo-controlled trial of early therapy in COVID-19 in health workers, their household members, and patients treated at IMSS (FANTAZE).

Background: The 2020 pandemic of SARS-CoV-2 causing COVID-19 disease is an unprecedented global emergency. COVID-19 appears to be a disease with an early phase where the virus replicates, coinciding with the first presentation of symptoms, followed by a later 'inflammatory' phase which results in severe disease in some individuals. It is known from other rapidly progressive infections such as sepsis and influenza that early treatment with antimicrobials is associated with a better outcome.

Human milk microbiota associated with early colonization of the neonatal gut in Mexican newborns.

Background: Human milk microbiota plays a role in the bacterial colonization of the neonatal gut, which has important consequences in the health and development of the newborn. However, there are few studies about the vertical transfer of bacteria from mother to infant in Latin American populations.

Methods: We performed a cross-sectional study characterizing the bacterial diversity of 67 human milk-neonatal stool pairs by high-throughput sequencing of V3-16S rDNA libraries, to assess the effect of the human milk microbiota on the bacterial composition of the neonate's gut at early days.

Gut Microbiota and Endothelial Dysfunction Markers in Obese Mexican Children and Adolescents.

Obesity is a metabolic disease characterized by low-grade inflammation and accompanied by dyslipidemia and up-regulation of other bioactive molecules, creating a predisposition to endothelial dysfunction and metabolic syndrome. We studied the association between gut microbiota diversity and endothelial dysfunction (EDF) markers in obese Mexican children and adolescents. We examined clinical data including metabolic factors and EDF markers in blood samples.

The gut microbiome of Mexican children affected by obesity.

Obesity is a metabolic disorder and global health issue. In Mexico 34.4% of children between 5 and 11 years-old are overweight or obese.

Profiling of bacterial and fungal communities of Mexican cheeses by high throughput DNA sequencing.

Cheese is a live food whose preparation involves procedures and microbial communities playing an important role for the final product. We characterized the bacterial and fungal diversity of seventeen different Mexican cheeses by high-throughput DNA sequencing of 16S/18S rDNA libraries. We propose the existence of bacterial and fungal core communities, where at genera level, bacteria include Streptococcus spp.

CYP2C9*3 gene variant contributes independently to glycaemic control in patients with type 2 diabetes treated with glibenclamide.

What Is Known And Objective: Glibenclamide is a prescribed glucose-lowering medication for diabetes, but there are interindividual variations in the therapeutic response. In this cross-sectional study, the aim was to explore the association of genetic variants in CYP2C9, ABCC8, KCNJ11 and TCF7L2 with good glycaemic control in Mexican type 2 diabetes (T2D) treated with glibenclamide.

Methods: Patients with T2D receiving treatment with glibenclamide or glibenclamide plus metformin were included.

Gut microbiome production of short-chain fatty acids and obesity in children.

Obesity has been a worldwide multifactorial epidemic malady for the last 2 decades. Changes in gut microbiota composition and its metabolites - short-chain fatty acids (SCFAs) - have been associated with obesity. Recent evidence suggests that SCFAs made by the gut microbiota may regulate directly or indirectly physiological and pathological processes in relation to obesity.

Carcinogenic risk of emerging persistent organic pollutant perfluorooctane sulfonate (PFOS): A proposal of classification.

Unlabelled: Perfluoroalkyls are stable synthetic chemicals, able to repel oils, fats and water. These compounds have been used in the manufacturing of products such as Teflon, lubricants, paints, fire-fighting foams, coatings for pans, carpets, clothes, and paperboard for packaging, among others. It is believed that populations are exposed constantly to them.

Expression of candidate genes associated with obesity in peripheral white blood cells of Mexican children.

Introduction: Obesity is a chronic, complex, and multifactorial disease, characterized by excess body fat. Diverse studies of the human genome have led to the identification of susceptibility genes that contribute to obesity. However, relatively few studies have addressed specifically the association between the level of expression of these genes and obesity.

The efficacy of the appetite suppressant, diethylpropion, is dependent on both when it is given (day vs. night) and under conditions of high fat dietary restriction.

Obesity is a public health problem caused by excessive consumption of high caloric diets and/or lack of physical activity. Although treatments for obesity include low caloric diets and exercise programs, these activities frequently are supplemented with appetite suppressants. For the short-term treatment of weight loss, diethylpropion (DEP) is a commonly used appetite suppressant.

Study of the diversity and short-chain fatty acids production by the bacterial community in overweight and obese Mexican children.

Obesity and overweight are health problems of multifactorial etiology, which may include changes in the microbiome. In Mexico, more than 30 % of the child population between 5 and 11 years of age suffer from being overweight or are obese, which makes it a public health issue in progress. The purpose of this work was to measure the short-chain fatty acid concentration by high-performance liquid chromatography (HPLC), and to characterize the bacterial diversity by ion torrent semiconductor sequencing, of 16S rDNA libraries prepared from stools collected from a sample of well-characterized Mexican children for normal weight, overweight, and obese conditions by anthropometric and biochemical criteria.

Allele frequency distribution of CYP2C9 2 and CYP2C9 3 polymorphisms in six Mexican populations.

Allele frequency differences of functional CYP2C9 polymorphisms are responsible for some of the variation in drug response observed in human populations. The most relevant CYP2C9 functional variants are CYP2C9*2 (rs1799853) and CYP2C9 3 (rs1057910). These polymorphisms show variation in allele frequencies among different population groups.
