COVID-19-Related Food Insecurity Among Households with Dietary Restrictions: A National Survey.

Background: Food insecurity dramatically increased because of the COVID-19 pandemic; however, little is known about pandemic-related food insecurity in households with dietary restrictions.

Objective: To examine pre-pandemic rates of and pandemic-related change in food insecurity among households with and without dietary restrictions.

Methods: A cross-sectional, panel-based survey of 3200 U.

Determining the Impact of Metabolic Nutrients on Autophagy.

Tumorigenesis relies on the ability of cancer cells to obtain necessary nutrients and fulfill increased energy demands associated with rapid proliferation. However, as a result of increased metabolite consumption and poor vascularization, most cancer cells must survive in a nutrient poor and high cellular stress microenvironment. Cancer cells undergo metabolic reprogramming to evade cell death and ensure proliferation; in particular, cancer cells utilize the catabolic process of autophagy.
