Hypertension in African Americans is a major clinical and public health problem because of the high prevalence and premature onset of elevated blood pressure (BP) as well as the high burden of co-morbid factors that lead to pharmacological treatment resistance (obesity, diabetes mellitus, depressed glomerular filtration rate, and albuminuria). BP control rates are lower in African Americans, especially men, than in other major race/ethnicity-sex groups; overall control rates are 29.9% for non-Hispanic Black men. Optimal antihypertensive treatment requires a comprehensive approach that encompasses multifactorial lifestyle modifications (weight loss, salt and alcohol restriction, and increased physical activity) plus drug therapy. The most important initial step in the evaluation of patients with elevated BP is to appropriately risk stratify them to allow determination of whether they are truly hypertensive and also to determine their goal BP levels. The overwhelming majority of African American hypertensive patients will require combination antihypertensive drug therapy to maintain BP consistently below target levels. The emphasis is now appropriately on utilizing the most effective drug combinations for the control of BP and protection of target-organs in this high-risk population. When BP is >15/10 mmHg above goal levels, combination drug therapy is recommended. The preferred combination is a calcium antagonist/angiotensin-converting enzyme inhibitor or, alternatively, in edematous and/or volume overload states, a thiazide diuretic/angiotensin-converting inhibitor.

Predictors of Health Care Disparities in Fuchs Dystrophy Treatment Using the IRIS Registry.
Cornea
January 2025
Department of Ophthalmology, University of Washington, Seattle, WA.
Purpose: To evaluate associations between sociodemographic factors and surgical management in patients with Fuchs Endothelial Corneal Dystrophy (FECD).
Methods: Patients >40 years old with FECD diagnosis and subsequent corneal edema between 2007 and 2020 were identified from the American Academy of Ophthalmology IRIS Registry (Intelligent Research in Sight). Multivariable Cox proportional hazards models were fit to examine the relationships between sociodemographic variables and time from FECD diagnosis to penetrating keratoplasty (PK) and endothelial keratoplasty (EK)/PK.
Increased Mortality in Kidney Transplant Recipients During the Delta/Omicron Era of the COVID-19 Pandemic Despite Widespread Vaccination.
Clin Transplant
January 2025
William J Von Liebig Center for Transplantation and Clinical Regeneration, Mayo Clinic, Rochester, Minnesota, USA.
Introduction: The incidence of mortality late in the pandemic, particularly after widespread vaccine availability, is not well understood. Herein, we elucidate the effect of this impact of the COVID pandemic as well as risk factors for mortality during it.
Methods: The primary end point was death with a functioning graft with secondary endpoints of mortality rates in subgroups and at different time intervals during the pandemic.
Access to Kidney Transplantation for Minority Children With End-Stage Renal Disease and Predictors of Post-Transplant Outcome: Impact of Race and Ethnicity.
Pediatr Transplant
February 2025
Connecticut Children's, Hartford, Connecticut, USA.
Background: Racial disparities in access to kidney transplantation (KT) have been described among children with end-stage renal disease in the United States. It has been suggested that these disparities stem from a combination of clinical and socioeconomic factors.
Methods: We evaluated data from the US Scientific Registry of Transplant Recipients (SRTR) of all pediatric (< 18 years old) KT recipients from 1999 to 2014 and compared outcomes by race or ethnicity: Hispanic, non-Hispanic Whites (NHW), and non-Hispanic Blacks (NHB).
Food insecurity and ultra-processed food consumption in the Health and Retirement Study: Cross-sectional analysis.
J Nutr Health Aging
January 2025
Department of Clinical Nutrition, King Abdulaziz University, Jeddah, Saudi Arabia; Department of Nutritional Sciences, University of Michigan, Ann Arbor, MI, United States. Electronic address:
Background: Higher ultra-processed foods (UPF), attributed to more than half of daily intake in the US, have been associated with impaired health outcomes. Documented evidence highlights disparities in UPF consumption due to food insecurity, which is a public health challenge among older adults in the US.
Objectives: The study examined the link between food insecurity and UPF consumption.
Designing a Multimodal and Culturally Relevant Alzheimer Disease and Related Dementia Generative Artificial Intelligence Tool for Black American Informal Caregivers: Cognitive Walk-Through Usability Study.
JMIR Aging

Luddy School of Informatics, Computing, and Engineering, Indiana University, Bloomington, IN, United States.
Background: Many members of Black American communities, faced with the high prevalence of Alzheimer disease and related dementias (ADRD) within their demographic, find themselves taking on the role of informal caregivers. Despite being the primary individuals responsible for the care of individuals with ADRD, these caregivers often lack sufficient knowledge about ADRD-related health literacy and feel ill-prepared for their caregiving responsibilities. Generative AI has become a new promising technological innovation in the health care domain, particularly for improving health literacy; however, some generative AI developments might lead to increased bias and potential harm toward Black American communities.
