In 2018, the federal government expanded the coverage duration of short-term limited-duration (STLD) health plans from 3 months to less than 12 months, with the option to renew for a total duration of up to 36 months. Some states imposed more stringent regulations than those federally imposed or banned the sale of these STLD plans, while other states did not have any additional regulations.

The U.S. Food and Drug Administration's (FDA) Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER) have collaborated with the European Medicines Agency (EMA) to develop a set of 10 guiding principles for good uses of artificial intelligence (AI) in drug development. The principles are aimed at industry members and product developers who are using AI to facilitate and accelerate drug/biological product development. 

In a prespecified interim analysis of a phase III trial (University of Texas MD Anderson Cancer Center Clinical Trial Consortium trial) reported in The Lancet, Frank et al found that intensity-modulated proton therapy (IMPT) was noninferior to standard intensity-modulated photon radiation therapy (IMRT) in progression-free survival among patients with stage III or IV oropharyngeal cancer.

A machine-learning model has calculated country-specific cancer mortality-to-incidence ratios and evaluated the factors that contribute the most to each country's survival gaps. Additionally, the artificial intelligence (AI) tool mapped out actions each country could take to improve cancer outcomes. A report explaining the establishment of the machine learning framework and its country-specific findings was published in Annals of Oncology.
