Pivot: partisan policy responses to COVID-19 health disparities.

How did partisanship influence rhetoric about, public opinion of, and policies that prioritize racial and ethnic health disparities of COVID-19 during the first wave of the pandemic between March and July 2020? In this retrospective, mixed-methods analysis using national administrative and survey data, we found that the rhetoric and policy of shared sacrifice diminished and partisan differences in pandemic policy increased once it became clear to political elites that there were major racial disparities in COVID-19 cases and deaths. We trace how first disparities emerged in data and then were reported in elite, national media, discussed in Congress, and reflected in public opinion. Once racial disparities were apparent, partisan divides opened in media, public opinion, and legislative activity, with Democrats foregrounding inequality and Republicans increasingly downplaying the pandemic.

Negative expectations (nocebo phenomenon) in clinical interventions: A scoping review.

Unpredictable, undesirable, and confusing reactions in the face of psychological or medical interventions make the clinical presentation more complicated and may represent clinically unexplained symptoms and also disturbed the doctor-patients relationship and decrease patients' benefits of treatment. It seems that negative expectations from the treatment (nocebo phenomenon) can explain such reactions. The aim of the current study is a scoping review and investigate different aspects of the nocebo phenomenon (negative expectations) in clinical interventions.
