Gene expression alterations have been implicated in suicide pathology. However, the study of the regulatory effect of DNA methylation on gene expression in the suicidal brain has been restricted to candidate genes. ⋯ The integration of different omic technologies provided novel candidates for the investigation of genes whose expression is altered in the suicidal brain and their potential regulatory mechanisms.

According to GLOBOCAN 2018 data1, cervical cancer (CC) is the fourth most common cancer in women worldwide and the third most frequent cancer in Mexican women. In recent years, incidence and mortality rates have been declining worldwide at a rate of 1.6% per year2.

Hepatocarcinogenesis has a variety of risk factors. In Mexico City, autopsies found 14% of hepatocellular carcinomas (HCCs) without cirrhosis. ⋯ There was no evidence of aflatoxin exposure in HCCs, with and without the known "classical" risk factors. One-third of non-cirrhotic HCCs had steatohepatitis or conditions associated to metabolic syndrome.

Pharmacogenomics (PGx), one of the several tools of precision medicine, has been slowly implemented in the clinic during the past decades. This process generally starts with direct and indirect genotype-phenotype associations of gene variants and drug efficacy, or adverse drug reactions, followed by replication and validation studies. Institutional efforts led by the PGx Research Network, The PGx Knowledge Base, and The Clinical Pharmacogenetics Implementation Consortium, mine all available data for further validation or research in additional populations. ⋯ Here, we aim to discuss the steps of this process and list existing actionable drug-gene pairs. Moreover, we describe the current status of PGx knowledge in populations from Mexico for actionable variants on the 19 genes listed by present PGx guidelines affecting 47 drugs. Our review collects current allele frequency information for these actionable variants, lists gaps of PGx information for relevant markers, and highlights the importance of continuing PGx research in Native and Mestizo populations.

Various studies suggest that perioperative concentrations of high-sensitivity troponins are incremental and predictive factors of a major adverse cardiac event (MACE) and all-cause mortality. ⋯ Pre-operative hs-cTnI was an independent predictive risk factor for MACE at 30-days and 1-year after noncardiac surgery and for all-cause mortality at 1-year after noncardiac surgery.
