Acute and chronic upper respiratory illnesses such as asthma, and allergic rhinitis (AR) have been linked to the presence of microorganisms in the nose. Microorganisms can exist in symbiotic or commensal relationships with the human body. However, in certain cases, opportunistic pathogens can take over, leading to altered states (dysbiosis) and causing disease. Thus, the microflora present in a host can be useful to reflect health status. The human body contains 10 trillion to 100 trillion microorganisms. Of these populations, certain pathogens have been identified to promote or undermine wellbeing. Therefore, knowledge of the microbiome is potentially helpful as a diagnostic tool for many diseases. Variations have been recognized in the types of microbes that inhabit various populations based on geography, diet, and lifestyle choices and various microbiota have been shown to modulate immune responses in allergic disease. Interestingly, the diseases affected by these changes are prevalent in certain racial or ethnic populations. These prevalent microbiome variations in these groups suggest that the presence of these microorganisms may be significantly associated with health disparities. We review current research in the search for correlations between ethnic diversity, microbiome communities in the nasal cavity and health outcomes in neurological and respiratory functions.
COVID-19 is a viral infection that resulted in a global pandemic. In the United States, COVID-19 caused incommensurate deaths, especially among members of minority groups. Previous literature shows comorbidities such as hypertension (HTN), diabetes mellitus (DM) and obesity (OBS) have been implicated in the severity of COVID-19 cases regardless of racial or ethnic group classification. However, minority populations, particularly people of African descent experienced higher mortality as they carry a disproportionately heavier burden in comorbidities cases. In this study we first confirm current literature on COVID-19 incidence and its correlation with the prevalence of comorbidities in various racial and ethnic populations, using anonymous and aggregated data from the Nashville General Hospital at Meharry, an Institute for the Study of Minority Health. We also evaluated the prevalence of comorbidities in minority patients and computed the correlation between the COVID-19 incidence and a permuted prevalence of comorbidities. A total of 959 patients were reviewed and our study indicates COVID-19 patients classified as Non-Hispanic Blacks (NHB) were approximately 3 times more likely to have an HTN or DM or both HTN and DM diagnosis. The chances double to be approximately six times higher when an OBS diagnosis is included singularly or in conjunction with either HTN or DM or both HTN and DM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
