Gut microbiota in preterm infants receiving breast milk or mixed feeding.

Background: Preterm birth is the leading cause of mortality in newborns, with very-low-birth-weight infants usually experiencing several complications. Breast milk is considered the gold standard of nutrition, especially for preterm infants with delayed gut colonization, because it contains beneficial microorganisms, such as and .

Aim: To analyze the gut microbiota of breastfed preterm infants with a birth weight of 1500 g or less.

Case Report: Molecular Characterization of Bloodstream Infections due to Carbapenem-Resistant Acinetobacter baumannii: A Pediatric Case Series.

Acinetobacter baumannii poses a significant threat to public health due to the high rate of multidrug-resistant strains. However, information on the molecular characterization of carbapenem-resistant Acinetobacter baumannii (CRAB) bloodstream infections in children is scarce. This study aimed to describe the molecular characterization of carbapenem-resistant A.

Pediatric Phaeohyphomycosis: A 44-Year Systematic Review of Reported Cases.

Background: Phaeohyphomycosis is an infection caused by pigmented fungi, which can be life-threatening in immunocompromised hosts and in disseminated disease. In adults with disseminated disease, mortality is as high as 79%. Data in children are derived from case reports and series.

Severe COVID-19 patients have severe vitamin D deficiency in Northeast Mexico.

Objective: the association between vitamin D and COVID-19 severity is not consistent. We compared prevalences and analyzed the association between vitamin D deficiency and COVID-19 severity in Northeast Mexico. Methods: this was a cross-sectional study with individuals consecutively included at a referral diagnostic center during March-September 2020 (n = 181).

Outcomes of transitional care programs on adolescent chronic inflammatory systemic diseases: systematic review and meta-analyses.

Background: Patients with juvenile chronic inflammatory systemic diseases (jCID) are vulnerable to many circumstances when transitioning to adult-centered healthcare; this increases the burden of disease and worsen their quality of life.

Methods: MEDLINE, Embase, Web of Science and Scopus were searched from inception to March 16, 2021. We included observational, randomized controlled trials and quasi-experimental studies that evaluated a transitional care program for adolescents and young adults with jCIDs.

Economic impact of Juvenile Idiopathic Arthritis: a systematic review.

Background: Juvenile Idiopathic Arthritis (JIA) requires complex care that generate elevated costs, which results in a high economic impact for the family. The aim of this systematic review was to collect and cluster the information currently available on healthcare costs associated with JIA after the introduction of biological therapies.

Methods: We comprehensively searched in MEDLINE, EMBASE, Web of Science, Scopus, and Cochrane Databases for studies from January 2000 to March 2021.

Seroprevalence of Anti-SARS-CoV-2 Antibodies in Blood Donors from Nuevo Leon State, Mexico, during 2020: A Retrospective Cross-Sectional Evaluation.

The progression and distribution of the SARS-CoV-2 pandemic are continuously changing over time and can be traced by blood donors' serological survey. Here, we investigated the seroprevalence of anti-SARS-CoV-2 antibodies in blood donors in Nuevo Leon, Mexico during 2020 as a strategy for the rapid evaluation of the spread of SARS-CoV-2 and asymptomatic case detection. We collected residual plasma samples from blood donors who attended two regional donation centers from January to December of 2020 to identify changes in anti-SARS-CoV-2 IgG prevalence.

Psychosocial and economic impact of rheumatic diseases on caregivers of Mexican children.

Background: Pediatric rheumatic disease (PRD) patients and their caregivers face a number of challenges, including the consequences of the PRD in patients and the impact on multiple dimensions of the caregivers' daily lives. The objective of this study is to measure the economic, psychological and social impact that PRD has on the caregivers of Mexican children.

Methods: This is a multicenter, cross-sectional study including primary caregivers of children and adolescents with PRD (JIA, JDM and JSLE) during April and November, 2019.

Are cord blood visfatin concentrations different depending on birth weight category?

Background And Objective: Increased visceral adipose tissue mass is strongly associated to metabolic disorders. Visfatin is a visceral fat adipocytokine. There is epidemiological evidence of a link between a suboptimal gestational environment and a greater propensity to develop metabolic disease in adult life.

[Vitamin D deficiency in Mexican mothers and their newborns].

Objective: The purpose of this study is to establish the prevalence of vitamin D deficiency and their newborns and analyze the risk factors related to this deficiency.

Methods: This is an observational, transversal, and prospective study. It included 191 puerperal women and their full-term newborns.

[Risk factors associated with intrauterine growth restriction in newborns attended in a university hospital].

Background: intrauterine growth restriction (IUGR) is related with neonatal morbidity and mortality. The detection and prenatal monitoring are necessary for an early intervention. The objective was to establish the prevalence and risk factors associated with intrauterine growth restriction in the university hospital Dr.

[Efficacy of sedation in outpatient procedures performed by pediatric residents].

Objective: To determine the efficacy of sedation in outpatient procedures performed by Pediatric Residents.
