Neutrophil-to-lymphocyte (NLR) and lymphocyte-to-C-reactive protein (LCR) ratios are used to predict severity and mortality in various infections. ⋯ INL > 12 e ILR < 0.03 son biomarcadores útiles para evaluar el riesgo de mortalidad en pacientes mexicanos con COVID-19 grave.

Fetal development is characterized by great plasticity and the ability to respond to environmental factors, where DNA methylation is essential for proper embryonic development. One-carbon metabolism provides methyl groups for methylation and fetal DNA development and is highly dependent on maternal nutritional status. During pregnancy, the supply of methyl donors is critical and the demand for nutrients that support this process, such as folate and vitamin B12, is increased. ⋯ Folate and vitamin B12 status have been associated with wide DNA methylation, as well as with specific genes related to neurological functions, embryonic development, energy metabolism, growth, and leptin. Furthermore, inadequate concentrations of both vitamins have been associated with an increased risk of perinatal outcomes such as neural tube defects, prematurity, low birth weight, pre-eclampsia, as well as maternal and infant obesity and insulin resistance, and decreased infant neurocognitive development. Supplementation, combined with a healthy diet, could be an essential strategy to prevent these results and improve maternal and fetal health.

This symposium describes the main characteristics of six Mexican scientific journals indexed in Journal Citation Reports: Archives of Medical Research, Revista de Investigación Clínica-Clinical and Translational Investigation, Gaceta Médica de México, Salud Pública de México, Cirugía y Cirujanos and Salud Mental. Particular emphasis is given to their historical and organizational aspects, as well as to their main achievements recognized by the national and international scientific community.

Influenza virus infection is often complicated by a bacterial infection, with this coinfection causing severe pneumonia. If not timely treated, the disease can cause death. ⋯ The groups of mice infected with Streptococcus pneumoniae or influenza virus alone showed no damage, which indicates that coexistence of these infections caused the damage in the group of co-infected mice.

The way in which two clinical procedures related to infant feeding are carried out in medical consultations for children younger than six months in a health center in Mexico City is analyzed. The first one refers to infants' anthropometric measurement, and the second, to feeding modalities' identification. Corrective actions are required based on the quality of children's health care in the public sector.
