Methods: Cross-sectional multicenter study within the Spanish Myo-Spain registry. Cases were classified as incident (≤ 12 months since diagnosis) and prevalent.

The , , and Virulotypes of the Type 3 Secretion System in Multidrug Resistant as a Death Risk Factor in Pediatric Patients.

The poor prognosis of infections associated with multidrug-resistant can be attributed to several conditions of the patient and virulence factors of the pathogen, such as the type III secretion system (T3SS), which presents the ability to inject four effectors into the host cell: ExoS, ExoT, ExoU and ExoY. The aim of this study was to analyze the distribution of genes through multiplex polymerase chain reaction in strains isolated from patients at a third-level pediatric hospital and their relationships with clinical variables, e.g.

Speed limits and their effect on air pollution in Mexico City: A quasi-experimental study.

Speed limits are an evidence-based intervention to prevent traffic collisions and deaths, yet their impact on air pollution in cities is understudied. The objective of this study was to investigate the association between lower speed limits and air pollution. We leverage the introduction of a new road safety policy in Mexico City in December 2015 which lowered speed limits, increased fines, and installed speed radars to enforce compliance.

Associated factors to non-medical and medical use of psychoactive medication among Mexican adolescents and adults in a national household survey.

Background: Non-medical use of psychoactive medication is a public health problem. Studies in other contexts indicate that individual sociodemographic characteristics are associated with non-medical use, but these associations have not been assessed in the Mexican context.

Objectives: To estimate the prevalence non-medical and medical use of psychoactive medication among Mexican adolescents and adults' medication users and to estimate the associations between sociodemographic characteristics and non-medical use of psychoactive medication, using data from a nationally representative sample.

Effect of prevalence of alcohol consumption and tobacco use in Mexican municipalities on early childhood development.

One of the most critical time periods in childhood is from birth to five years of age. Children exposed to alcohol and/or tobacco via family members and neighborhood are at risk for childhood developmental delays. This study evaluated the association of early childhood development with the prevalence of alcohol consumption and tobacco use in Mexican municipalities.

Dysbiosis by Eradication of Infection Associated with Follicular Gastropathy and Pangastropathy.

Dysbiosis plays an important role in the development of bacterial infections in the gastric mucosa, particularly . The international guidelines for the treatment of infections suggest standard triple therapy (STT). Nevertheless, because of the increasing resistance rates to clarithromycin, metronidazole has been widely considered in several countries.

Economic Cost of the Waste of Anti-inflammatory and Analgesic Drugs in Mexico City.

Anti-inflammatory and analgesic medications (AAMs) are widely used in Mexico and the rest of the world. Their excessive acquisition can lead to waste, representing an unnecessary expense for families and the public health system. The aim of this study was to estimate the economic cost of the waste of unused AAMs collected by the National System for the Collection of Residues of Containers and Medications (SINGREM, the acronym in Spanish) in Mexico City during 2019.

Variation in youth and young adult homicide rates and their association with city characteristics in Latin America: the SALURBAL study.

Background: Latin America and the Caribbean (LAC) is one of the most urbanized and violent regions worldwide. Homicides in youth (15-24 years old, yo) and young adults (25-39yo) are an especially pressing public health problem. Yet there is little research on how city characteristics relate to homicide rates in youth and young adults.

Impact of environmental and individual factors on COVID-19 mortality in children and adolescents in Mexico: An observational study.

Background: During the Covid-19 pandemic, children and adolescents faced poverty, potentially dying from preventable causes, or missing out essential vaccines. The aim of this study was to assess potential environmental and individual factors associated to COVID-19 mortality in children and adolescents in Mexico.

Methods: This cross-sectional study analysed the official data of 131,001 children under 10 years of age and adolescents between 10 and 19 years of age with COVID-19 disease, in Mexico.

Early childhood development and urban environment in Mexico.

Background: Childhood is considered the most important phase of human development; within it the period from birth to 5 years of age is particularly critical, given the speed at which changes occur. The context where children live can influence early childhood developmnent (ECD) by providing or limiting opportunities to learn, play and establish social interactions. This study explored the associations between characteristics of the urban environment and ECD in 2,194 children aged 36 to 59 months living in urban municipalities in Mexico.

Climate Trends and Consumption of Foods and Beverages by Processing Level in Mexican Cities.

Little is known about the potential impact of climate change on food systems and diet. We aimed to estimate the association of changes in rainfall and temperatures with consumption of unprocessed and processed foods among residents of Mexican cities by climate region. We analyzed 3,312 participants of the 2012 Mexican National Health and Nutrition Survey with dietary intake and sociodemographic information linked to historical rainfall and temperature data collected by the Mexican National Weather Service.

Effects of air pollution and climatology on COVID-19 mortality in Spain.

Unlabelled: The health, economic, and social impact of COVID-19 has been significant across the world. Our objective was to evaluate the association between air pollution (through NO and PM levels) and COVID-19 mortality in Spanish provinces from February 3, 2020, to July 14, 2020, adjusting for climatic parameters. An observational and ecological study was conducted with information extracted from Datadista repository (Datadista, 2020).

Satisfaction With Healthcare Services Among Patients With Diabetes, Hypertension, and/or Dyslipidemia in Mexico: A Cross-Sectional Study.

Objectives: To examine the factors associated with satisfaction with healthcare services provided to patients with diabetes, hypertension, and/or dyslipidemia in the Mexican population.

Methods: In a cross-sectional, retrospective study, we used data from the 2016 Half-Way National Health and Nutrition Survey in Mexico (ENSANUT MC 2016). This contained self-reported information about patient satisfaction and use of healthcare services by 2529 adults.

Novel HLA class I associations with HIV-1 control in a unique genetically admixed population.

Associations between HLA class I alleles and HIV progression in populations exhibiting Amerindian and Caucasian genetic admixture remain understudied. Using univariable and multivariable analyses we evaluated HLA associations with five HIV clinical parameters in 3,213 HIV clade B-infected, ART-naïve individuals from Mexico and Central America (MEX/CAM cohort). A Canadian cohort (HOMER, n = 1622) was used for comparison.

Antiquorum Sensing Activity of Seed Oils from Oleaginous Plants and Protective Effect During Challenge with Chromobacterium violaceum.

Seed oils from oleaginous plants are rich in fatty acids (FAs) that play important roles in the health of the consumers. Recent studies indicate that FA also can play an important role in communication and regulation of virulence in bacteria. Nevertheless, evidence demonstrating protection against bacterial infections mediated by their quorum sensing inhibition (QSI) activity is scarce.

Objective: Heart failure (HF) is an important public health problem due to its increasing prevalence, and the decompensation associated with hospital admission represents an increased risk of death. The objective of this study was to compare several methods to model the variable hospitalizations and to determine the effect of factors associated with hospital admissions in incident cases of HF.

Methods: Study of a retrospective cohort of patients with information extracted from electronic medical records of PC was performed.
