Overlooked and Damaging Impact of Structural Racism and Implicit Bias on US Health Care: Overarching Policy Implications.

Marginalized populations, including racial and ethnic minorities, have historically faced significant barriers to accessing quality health care because of structural racism and implicit bias. A brief review and analysis of past and historic and current policies demonstrate that structural racism and implicit bias continue to underscore a health system characterized by unequal access and distribution of health care resources. Although advances in cancer care have led to decreased incidence and mortality, not all populations benefit.

Correction to: Multiple selective sweeps of ancient polymorphisms in and around LTα located in the MHC class III region on chromosome 6.

After publication of our article [1] we were notified that a few duplicate sentences were included on Figure 3 and Figure 4 legends.

Multiple selective sweeps of ancient polymorphisms in and around LTα located in the MHC class III region on chromosome 6.

Background: Lymphotoxin-α (LTα), located in the Major Histocompatibility Complex (MHC) class III region on chromosome 6, encodes a cytotoxic protein that mediates a variety of antiviral responses among other biological functions. Furthermore, several genotypes at this gene have been implicated in the onset of a number of complex diseases, including myocardial infarction, autoimmunity, and various types of cancer. However, little is known about levels of nucleotide variation and linkage disequilibrium (LD) in and near LTα, which could also influence phenotypic variance.
