Genetic variation at the MYH9 locus is linked to the high incidence of focal segmental glomerulosclerosis (FSGS) and non-diabetic end-stage renal disease among African Americans. To further define risk alleles with FSGS we performed a genome-wide association analysis using more than one million single-nucleotide polymorphisms in 56 African-American and 61 European-American patients with biopsy-confirmed FSGS. Results were compared to 1641 European Americans and 1800 African Americans as unselected controls. While no association was observed in the cohort of European Americans, the case-control comparison of African Americans found variants within a 60 kb region of chromosome 22 containing part of the APOL1 and MYH9 genes associated with increased risk of FSGS. This region spans different linkage disequilibrium blocks, and variants associating with disease within this region are in linkage disequilibrium with variants which have shown signals of natural selection. APOL1 is a strong candidate for a gene that has undergone recent natural selection and is known to be involved in the infection by Trypanosoma brucei, a parasite common in Africa that has recently adapted to infect human hosts. Further studies will be required to establish which variants are causally related to kidney disease, what mutations caused the selective sweep, and to ultimately determine if these are the same.

Nowcasting to Monitor Real-Time Mpox Trends During the 2022 Outbreak in New York City: Evaluation Using Reportable Disease Data Stratified by Race or Ethnicity.

Online J Public Health Inform

January 2025

Bureau of Communicable Disease, New York City Department of Health and Mental Hygiene, Long Island City, NY, United States.

Background: Applying nowcasting methods to partially accrued reportable disease data can help policymakers interpret recent epidemic trends despite data lags and quickly identify and remediate health inequities. During the 2022 mpox outbreak in New York City, we applied Nowcasting by Bayesian Smoothing (NobBS) to estimate recent cases, citywide and stratified by race or ethnicity (Black or African American, Hispanic or Latino, and White). However, in real time, it was unclear if the estimates were accurate.

Using administrative and survey data, we show that there has been a sea change in the contours of American imprisonment. At the end of the twentieth century, inequality in the prison admission rates of Black and White Americans was comparable to inequality in the prison admission rates of people with and without a college education. However, educational inequality is now much greater than racial inequality in prison admissions for all major crime types.

Background: Hypertension, a leading global risk factor for mortality and disability, disproportionately affects racial and ethnic minorities. Our study investigates the association between the type of prior antihypertensive medication use and the likelihood of cardiovascular events (CVE) and assesses whether the patient's race influences this relationship.

Methods: A retrospective study of 14 836 hypertension cases aged ≥ 40 years was conducted using data from HCA Healthcare between 2017 and 2023.

Background: In the United States, African/Black American (henceforth Black) men face significantly higher mortality rates from colorectal cancer (CRC) compared to other gender, racial, and ethnic groups. Although CRC is preventable and treatable with early detection, screening rates among Black men remain low. This study aimed to synthesize existing literature on the barriers and facilitators (determinants) of CRC screening to offer guidance to primary care teams in their efforts to improve screening uptake.

Background: With 8.4% of Americans uninsured, free clinics serve as essential safety nets for underserved populations. This study compared the demographics of the patients of a student-run free to Toledo, Ohio, and national census data to evaluate health needs, barriers to care, and the characteristics of the underserved population.
