The Effect of Vaccine Hesitancy on Racial and Ethnic Minority Children During the COVID-19 Pandemic.

The coronavirus disease 2019 (COVID-19) outbreak has ravaged the world, with numerous cases disproportionally attributed to the United States due to vaccine hesitancy. One vulnerable group that has been affected by vaccine hesitancy is the pediatric population, particularly those in racial and ethnic minority groups. To improve health outcomes and vaccination rates, we must first understand the factors contributing to vaccine hesitancy and its subsequent influence on the pediatric population. The medical community can better tailor public health strategies by analyzing historical and current events contributing to COVID-19 vaccine hesitancy. A comprehensive approach will improve the health of children and society as a whole. [Pediatr Ann. 2022;51(3):e107-e111.].

A lateral hypothalamus to basal forebrain neurocircuit promotes feeding by suppressing responses to anxiogenic environmental cues.

Animals must consider competing information before deciding to eat: internal signals indicating the desirability of food and external signals indicating the risk involved in eating within a particular environment. The behaviors driven by the former are manifestations of hunger, and the latter, anxiety. The connection between pathologic anxiety and reduced eating in conditions like typical depression and anorexia is well known. Conversely, anti-anxiety drugs such as benzodiazepines increase appetite. Here, we show that GABAergic neurons in the diagonal band of Broca (DBBGABA) are responsive to indications of risk and receive monosynaptic inhibitory input from lateral hypothalamus GABAergic neurons (LHGABA). Activation of this circuit reduces anxiety and causes indiscriminate feeding. We also found that diazepam rapidly reduces DBBGABA activity while inducing indiscriminate feeding. Our study reveals that the LHGABA→DBBGABA neurocircuit overrides anxiogenic environmental cues to allow feeding and that this pathway may underlie the link between eating and anxiety-related disorders.
