Characteristics of the Occlusal Plane Associated with Unilateral and Bilateral Articular Eminence Inclination: A Cross-Sectional CBCT Study.

The characteristics of the temporomandibular joint (TMJ) are essential in orthodontic and prosthetic treatments. Previous studies have suggested an association between articular eminence inclinations (AEI) and occlusal plane characteristics using radiographs, but no bilateral analysis has been conducted using cone beam computed tomography (CBCT). This study aimed to investigate the specific characteristics of the occlusal plane inclinations associated with unilateral and bilateral AEI using CBCT.

[Impact of self-reported periodontal status on oral health-related quality of life in adult population with Type 2 Diabetes from Mexico City].

Objective: Periodontitis ranks sixth as a type 2 diabetes (T2D) complication. According to its severity, it may cause pain, discomfort and tooth loss. The aim of this study was to evaluate the impact of self-reported periodontal status on the Oral Health Related Quality of Life (OHRQoL) of people with T2D.

Social determinants of health for moderate and severe periodontal disease in rural and urban populations.

Objective: We assessed the prevalence of moderate and severe periodontitis and its association with social determinants of health in rural and urban population from the State of Chiapas, in Southern Mexico.

The determinants were categorized as proximal (age, sex, indigenous origin, diabetes, smoking, diet), intermediate (level of schooling, occupation, medical and dental care), and structural (type of institution of health care provision, residence area).

Two-year follow-up of the COVID-19 pandemic in Mexico.

Background: After the initial outbreak in China (December 2019), the World Health Organization declared COVID-19 a pandemic on March 11, 2020. This paper aims to describe the first 2 years of the pandemic in Mexico.

Knowledge, attitudes, perceptions, and COVID-19 hesitancy in a large public university in Mexico city during the early vaccination rollout.

Background: Vaccination against COVID-19 is a primary tool for controlling the pandemic. However, the spread of vaccine hesitancy constitutes a significant threat to reverse progress in preventing the disease. Studies conducted in Mexico have revealed that vaccination intention in Mexico among the general population ranges from 62 to 82%.

Clinical and Virological Features of Patients Hospitalized with Different Types of COVID-19 Vaccination in Mexico City.

Coronavirus disease 2019 (COVID-19) vaccines effectively protect against severe disease and death.

This work aimed to compare COVID-19 clinical presentations and outcomes in vaccinated and unvaccinated patients in Mexico City.

Dominance of Three Sublineages of the SARS-CoV-2 Delta Variant in Mexico.

In this study, we analyzed the sequences of SARS-CoV-2 isolates of the Delta variant in Mexico, which has completely replaced other previously circulating variants in the country due to its transmission advantage. Among all the Delta sublineages that were detected, 81.5 % were classified as AY.

The Alpha Variant (B.1.1.7) of SARS-CoV-2 Failed to Become Dominant in Mexico.

During the coronavirus disease 2019 (COVID-19) pandemic, the emergence and rapid increase of the B.1.1.

Transmission dynamics and forecasts of the COVID-19 pandemic in Mexico, March-December 2020.

Mexico has experienced one of the highest COVID-19 mortality rates in the world. A delayed implementation of social distancing interventions in late March 2020 and a phased reopening of the country in June 2020 has facilitated sustained disease transmission in the region. In this study we systematically generate and compare 30-day ahead forecasts using previously validated growth models based on mortality trends from the Institute for Health Metrics and Evaluation for Mexico and Mexico City in near real-time.

Dyslipidemia and severe periodontitis among patients with type 2 diabetes.

Social determinants for overweight and obesity in a highly marginalized population from Comitán, Chiapas, Mexico.

Objective: We assessed the prevalence of overweight and obesity and its association with some social determinants in a highly marginalized population in Mexico.

Materials And Methods: Cross-sectional study conducted in Comitán, Chiapas, from 2010 to 2012, comprising 1 858 subjects aged ≥20 years. We evaluated proximal, intermediate, and structuralsocial determinants.

DISPERSION OF A NEW CORONAVIRUS SARS-COV-2 BY AIRLINES IN 2020: TEMPORAL ESTIMATES OF THE OUTBREAK IN MEXICO.

Background: On January 23, 2020, China imposed a quarantine on the city of Wuhan to contain the SARS-CoV-2 outbreak. Regardless of this measure, the new infection has spread to several countries around the world.

Objective: We developed a method to study the dissemination of this infection by airline routes and provide estimations of the time of arrival of the outbreak to different cities.

Guillain-Barré Syndrome Associated With Zika Virus Infection: A Prospective Case Series From Mexico.

On May 2016, anticipating the rainy season from June to October in Mexico, we expected an increase in cases of Zika virus (ZIKV) infections. With the goal of identifying cases of GBS associated with ZIKV infection, a prospective joint study was conducted by a reference center for neurological patients and the Secretary of Health in Mexico City from July 2016 to November 2016. Serum, cerebrospinal fluid, urine, and saliva were tested by RT-PCR for ZIKV, dengue virus, and chikungunya virus in patients referred from states with reported transmissions of ZIKV infection, and with clinical symptoms of GBS according to the Brighton Collaboration criteria.

Disparities in prediabetes and type 2 diabetes prevalence between indigenous and nonindigenous populations from Southeastern Mexico: The Comitan Study.

Aims: In this research we assessed the prevalence of prediabetes and type 2 diabetes and its association with social determinants such as indigenous origin and residence area in population from Comitan, Chiapas, Mexico.

Methods: The Comitan Study is a population-based study carried out from 2010 to 2012 that included 1844 participants aged ≥ 20 years, 880 indigenous and 964 nonindigenous participants. Ethnicity was ascertained by self-report and speaking an indigenous language was also recorded.

The burden of influenza A and B in Mexico from the year 2010 to 2013: An observational, retrospective, database study, on records from the Directorate General of Epidemiology database.

Despite vaccination programs, influenza still represents a significant disease burden in Mexico. We conducted an observational, retrospective analysis to better understand the epidemiological situation of the influenza virus in Mexico. Analysis of the seasonal patterns of influenza A and B were based on the Directorate General of Epidemiology dataset of influenza-like illness(ILI), and severe acute respiratory infection(SARI) that were recorded between January 2010 and December 2013.

Low complexity regions (LCRs) contribute to the hypervariability of the HIV-1 gp120 protein.

Low complexity regions (LCRs) are sequences of nucleic acids or proteins defined by a compositional bias. Their occurrence has been confirmed in sequences of the three cellular lineages (Bacteria, Archaea and Eucarya), and has also been reported in viral genomes. We present here the results of a detailed computer analysis of the LCRs present in the HIV-1 glycoprotein 120 (gp120) encoded by the viral gene env.
