COVID-19's impact on maternal mortality demands rethink of public health strategies

During the peak of the SARS-CoV-2 pandemic, there was an increase in maternal mortality in Chile. This is confirmed by a natural population experiment based on data from the Department of Health Statistics and Information (DEIS) of the Chilean Ministry of Health. The research was published in PLOS Global Public Health.

New strategy for mRNA nanocarriers using triphenyl phosphonium

Among the vastly different ways of tackling a disease, controlling the genetic expression of cells is undoubtedly one of the most powerful. Over the past few decades, scientists have come up with dozens of innovative strategies that involve using messenger RNA (mRNA) to 'force' cells to build specific proteins. These mRNA-based therapies have recently gained prominence as vaccines against infectious diseases like COVID-19. Additionally, they hold significant potential for treating cancer and genetic disorders.

Study finds no direct link between pandemic social distancing and neonatal mortality

A recent study in JAMA Network Open found no significant link between social distancing during the COVID-19 pandemic and overall neonatal mortality rates in the U.S., though a two-month lag indicated some increase in early neonatal deaths and preterm births.

COVID vaccines and infections in early pregnancy show no increased risk of birth defects in large Nordic study

Research on 343,066 infants across Denmark, Sweden, and Norway shows no increased risk of congenital anomalies from COVID-19 infections or vaccinations during the first trimester. The study confirms safety, supporting vaccination recommendations for pregnant women.

High mutation count in new COVID-19 variants does not increase immune evasion, study finds

New research from UNC Charlotte's Center for Computational Intelligence to Predict Health and Environmental Risks (CIPHER) has found that the two recent and prevalent strains of the virus that cause COVID-19, SARS-CoV-2 variants BA.2.86 and JN.1, are not significantly better than their predecessor Omicron at evading immune responses and causing infections despite having a high number of mutations compared to Omicron.

New insights into modified nucleoside synthesis

The genetic information on DNA is transcribed into messenger RNA (mRNA) and translated to the amino acid sequence by transfer RNA (tRNA) on the ribosome. Modified nucleosides within RNA are involved in maintaining and regulating the protein synthesis system.
