Background: Influenza (flu) and COVID-19 vaccination rates are subpar across the US, especially in racial and/or socioeconomic minority groups who are understudied in public health literature. Objective: The objective of this mixed-methods study was to elucidate attitudes of patients at the Turtle Creek Primary Care Center, a clinic that cares for ∼70% non-white patients, towards flu and COVID-19 vaccines, with the goal of establishing vaccine education gaps and increasing vaccine uptake in minority communities. Design/Patients: This study was conducted as a cross-sectional analysis. Authors completed 123 patient phone surveys of patients cared for at the Turtle Creek clinic inquiring about flu and COVID-19 infection status and vaccination uptake (August 26–October 10, 2021). Approach/Key Results: We found that rates of vaccination were subpar in the Turtle Creek community, with only 54% having received the COVID-19 vaccine and only 44% receiving the flu vaccine regularly. There was a strong association between COVID-19 and flu vaccine acceptance and a notable correlation between vaccine acceptance and age. When assessing how vaccine acceptance was influenced by trusted sources of information, those who cited trusting "medical professionals" and "word of mouth" had higher odds of COVID-19 vaccine acceptance but those who cited trusting "social media" had decreased odds of acceptance. Finally, we uncovered 14 common factors for either vaccine acceptance or refusal that clustered into four overarching themes of trust, need, safety, and availability. Conclusion: These data highlight the necessity of improved vaccine education and reveal targetable populations and approaches for disseminating vaccine information. [ABSTRACT FROM AUTHOR]

We previously reported that acute and selective activation of GABA-releasing parafacial zone (PZVgat) neurons in behaving mice produces slow-wave-sleep (SWS), even in the absence of sleep deficit, suggesting that these neurons may represent, at least in part, a key cellular substrate underlying sleep drive. It remains, however, to be determined if PZVgat neurons actively maintain, as oppose to simply gate, SWS. To begin to experimentally address this knowledge gap, we asked whether activation of PZVgat neurons could attenuate or block the wake-promoting effects of two widely used wake-promoting psychostimulants, armodafinil or caffeine. We found that activation of PZVgat neurons completely blocked the behavioral and electrocortical wake-promoting action of armodafinil. In some contrast, activation of PZVgat neurons inhibited the behavioral, but not electrocortical, arousal response to caffeine. These results suggest that: (1) PZVgat neurons actively maintain, as oppose to simply gate, SWS and cortical slow-wave-activity; (2) armodafinil cannot exert its wake-promoting effects when PZVgat neurons are activated, intimating a possible shared circuit/molecular basis for mechanism of action; (3) caffeine can continue to exert potent cortical desynchronizing, but not behavioral, effects when PZVgat neurons are activated, inferring a shared and divergent circuit/molecular basis for mechanism of action; and 4) PZVgat neurons represent a key cell population for SWS induction and maintenance.
