Determination of evolutionary mechanisms underlying innovative traits is crucial for understanding the vast diversity of species and phenotypes. Given their respiratory physiologies, fishes are compelling subjects for evolutionary analysis of the hemoprotein-based oxygen-transport systems. Asian noodlefishes (Osmeriformes: Salangidae) and Antarctic icefishes (Notothenioidei: Channichthyidae) are examples of fish clades that generally do not express myoglobin or hemoglobin.

Tetraodontiformes species exhibit several evolutionary innovations, notably the convergent evolution of two traits in some clades: defensive body inflation and the loss of acid-peptic digestion. It has been widely believed that the evolution of body inflation drove the loss of gastric digestion, as ingesting seawater during inflation would hinder acidification and ultimately lead to the loss of gastric digestion. Leveraging accumulating genome resources, we investigated the presence, synteny, gene expression, and rapid evolution of nine genes associated with acid-peptic digestion across seven species from four Tetraodontiformes families, representing two branches that underwent convergent evolution.

The stomach has been a highly conserved organ throughout vertebrate evolution; however, there are now over 20 lineages composed of monotremes, lungfish and teleost fish displaying a secondary loss of stomach function and morphology. This "agastric phenotype" has evolved convergently and is typified by a loss of gastric glands and gastric acid secretion and a near-to-complete loss of storage capacity of the stomach. All agastric species have lost the genes for gastric enzymes ( and ) and proton pump subunits ( and ), and gastrin () has been lost in monotremes.

Introduction: The continuous increase in chronic non-communicable diseases requires strengthening primary care preventive strategies. In Chile, preventive health screening is a national strategy focused on identifying adults with risk factors, including hypertension, diabetes, and dyslipidemia, among others. It is broadly implemented in primary care and has associated performance resources.
