Association between methyl-CpG-binding domain protein 5 gene and depressive symptoms in Mexican population: Results from MxGDAR/Encodat cohort.

Objective: To explore the association between 75 candidate genes previously reported in subjects with anxiety symptoms (AS) and depressive symptoms (DS) in a Mexican cohort.

Methods: The sample included 2012 individuals from the Mexican Genomic Database for Addiction Research (MxGDAR/Encodat) cohort, 198 showed AS, 266 DS, 66 anxiety and depressive symptoms (ADS), and 1482 healthy controls. The DI-PAD screening questionnaire was used to evaluate lifetime AS and DS.

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.

Anion-π catalysis on carbon allotropes.

Anion-π catalysis, introduced in 2013, stands for the stabilization of anionic transition states on π-acidic aromatic surfaces. Anion-π catalysis on carbon allotropes is particularly attractive because high polarizability promises access to really strong anion-π interactions. With these expectations, anion-π catalysis on fullerenes has been introduced in 2017, followed by carbon nanotubes in 2019.

Transmitted Drug Resistance and HIV Diversity Among Adolescents Newly Diagnosed With HIV in Spain.

Background: Virologic characterization of newly HIV-diagnosed adolescents could help to improve their specific needs. The objective was to describe the transmitted drug resistance mutations (TDR) and its transmission by clusters in this population in Spain.

Methods: TDR to retrotranscriptase and protease inhibitors included in the WHO TDR list 2009 implemented in the Calibrated Population Resistance tool v8.
