Since 1977, the World Health Organization publishes a list of essential medicines, i.e., those that satisfy the priority health care needs of the population and are selected with regard to disease prevalence and public health relevance, evidence of clinical efficacy, and safety, as well as comparative costs and cost-effectiveness. The Essential Medicines List (EML) is an invaluable tool for all countries to select those medicines that have an excellent risk/benefit ratio and that are reputed to be of pivotal importance to health. In the present perspective, we describe the chemical composition and the main features of the small molecules that are included in the EML, spanning from their origin, to their stereochemistry and measure of drug-likeness. Most and foremost, we wish to disseminate the importance of the EML, which can be both a helpful teaching tool in an ever-expanding world of medicines and an inspiration for those involved in pharmaceutical R&D.

Human mitochondrial DNA (mtDNA) harbors essential mutations linked to aging, neurodegenerative diseases, and complex muscle disorders. Due to its uniparental and haploid inheritance, mtDNA captures matrilineal evolutionary trajectories, playing a crucial role in population and medical genetics. However, critical questions about the genomic diversity patterns, inheritance models, and evolutionary and medical functions of mtDNA remain unresolved or underexplored, particularly in the transition from traditional genotyping to large-scale genomic analyses.

Thoracic and abdominal aortic aneurysm poses a substantial mortality risk in adults, yet many of its underlying factors remain unidentified. Here, we identify mitochondrial nicotinamide adenine dinucleotide (NAD)⁺ deficiency as a causal factor for the development of aortic aneurysm. Multiomics analysis of 150 surgical aortic specimens indicated impaired NAD salvage and mitochondrial transport in human thoracic aortic aneurysm, with expression of the NAD transporter SLC25A51 inversely correlating with disease severity and postoperative progression.

Background: Colorectal cancer screening with fecal immunochemical testing (FIT) is a process that depends on diagnostic colonoscopy for those with a positive test and completion of colonoscopy after positive FIT is an essential element of program effectiveness.
Aims: We examined how the COVID-19 pandemic influenced completion of diagnostic colonoscopy after positive FIT in our integrated healthcare system.
Methods: This was a retrospective study of all positive FIT over a 5-year period.

Over the past two decades, genomic sequencing (exome and genome) has proven to be critical in providing a faster and more accurate diagnosis as well as tailored treatment plans for a variety of populations. Despite its potential, disparities in access to genomic sequencing persist, predominantly among underrepresented and socioeconomically disadvantaged groups and populations. This inequity stems from factors such as: 1) high costs of sequencing, 2) significant gaps in insurance coverage, 3) limited availability of genetic services in many healthcare institutions and geographic areas, and 4) lack of diversity in genetic research and databases.
