There has been much interest in environmental temperature and race as modulators of Coronavirus disease-19 (COVID-19) infection and mortality. However, in the United States race and temperature correlate with various other social determinants of health, comorbidities, and environmental influences that could be responsible for noted effects. This study investigates the independent effects of race and environmental temperature on COVID-19 incidence and mortality in United States counties. ⋯ Higher environmental temperatures correlated with reduced COVID-19 cases, but this benefit does not yet appear in mortality models. Black race was an independent risk factor for increased COVID-19 cases and deaths. Thus, many proposed mechanisms through which Black race might increase risk for COVID-19, such as socioeconomic and healthcare-related predispositions, are inadequate in explaining the full magnitude of this health disparity.

Infection is postulated as a possible risk factor for ischemic heart disease with a spiralling body of evidence. Hepatitis B is one of the most comprehensively investigated infection for its association with ischemic heart disease. This study aims at establishing an association between Hepatitis B core antibody status and ischemic heart disease using National Health and Nutrition Examination Survey (NHANES) database. ⋯ In conclusion, the present analysis points toward a possible association between past Hepatitis B infection and ischemic heart disease. Hepatitis B infection was associated with a decreased incidence of ischemic heart disease. Further research with better design and possible molecular mechanism is warranted.

Targeted Temperature Management (TTM) is a class I recommendation for the management of sudden cardiac arrest (SCA) patients with presumed brain injury. We aimed to study trends, predictors and outcomes in SCA patients from a nationally represented US population sample. ⋯ Although TTM utilization increased over our study period, the overall application of TTM was still dismal. Factors that circumvent TTM utilization need to be addressed in future studies so more eligible patients could benefit from this life saving therapy.
