The impact of COVID-19 and housing insecurity on lower-income Black women.

During the COVID-19 pandemic, multiple groups faced increased risks for negative health and mortality. Using an intersectional framework, the current study explores how the global pandemic impacted lower-income women living in the United States through access to housing. Findings indicate several challenges  remaining stably housed during the pandemic. Major themes included: (1) High-Risk Survival Economies, (2) Landlord Stress, Deception, and Exclusion, (3) Landlord Harassment, (4) Low Levels of Formal and Informal Support, (5) Housing as a Health Risk Factor, and (6) Resilience. These themes are explored through four in-depth narrative accounts. Implications for health and policy are discussed. Future research that examines and engages with both direct (e.g., material scarcity) and indirect (e.g., discrimination) pathways that connect housing to health are strongly encouraged.

Lateral hypothalamic LEPR neurons drive appetitive but not consummatory behaviors.

Assigning behavioral roles to genetically defined neurons within the lateral hypothalamus (LH) is an ongoing challenge. We demonstrate that a subpopulation of LH GABAergic neurons expressing leptin receptors (LHLEPR) specifically drives appetitive behaviors in mice. Ablation of LH GABAergic neurons (LHVGAT) decreases weight gain and food intake, whereas LHLEPR ablation does not. Appetitive learning in a Pavlovian conditioning paradigm is delayed in LHVGAT-ablated mice but prevented entirely in LHLEPR-ablated mice. Both LHVGAT and LHLEPR neurons bidirectionally modulate reward-related behaviors, but only LHVGAT neurons affect feeding. In the Pavlovian paradigm, only LHLEPR activity discriminates between conditioned cues. Optogenetic activation or inhibition of either population in this task disrupts discrimination. However, manipulations of LHLEPR→VTA projections evoke divergent effects on responding. Unlike food-oriented learning, chemogenetic inhibition of LHLEPR neurons does not alter cocaine-conditioned place preference but attenuates cocaine sensitization. Thus, LHLEPR neurons may specifically regulate appetitive behaviors toward non-drug reinforcers.
