Available evidence allows the interpretation that some cases of absence of otherwise expected variation, based on phylogenetic expectations in mitogenomes of Native American origin, are due to artificial recombination rather than to homoplasy, while other more complex scenarios involving combination of original Cambridge Reference Sequence mistakes plus incomplete or incorrect scoring of variation are also showed. Several instances of mismatched control and coding regions as well as partially duplicated HV2 are observed in Peruvians, while intra-haplogroup chimaeras of different D1 subhaplogroups are referred to in Mexican Native Americans. A revised definition for haplogroup B2h is proposed, and preventive quality control measures are suggested.

J Racial Ethn Health Disparities
January 2025
Epidemiology and Health Economics Research (EHER), Universidad Científica del Sur, Lima, Peru.
Background: The Afro-Peruvian population is one of the ethnic minorities most affected by cultural, socioeconomic, and health barriers; however, there is little evidence on health inequalities in this ethnic group. Therefore, We aimed to determine health inequalities among the Peruvian Afro-descendant population in comparison with non-Afro-descendants.
Methods: A cross-sectional study was conducted using data from the Demographic and Family Health Survey 2022.
Introduction: This report uses data from the 2023 National Health Interview Survey to provide updated percentages of adults who experienced chronic pain and high-impact chronic pain in the past 3 months by selected demographic characteristics and urbanization level.
Methods: Point estimates and corresponding confidence intervals for this analysis were calculated using SAS-callable SUDAAN software to account for the complex sample design of the National Health Interview Survey. Differences between percentages were evaluated using two-sided significance tests at the 0.
Alzheimers Dement
December 2024
Dementia Research Unit/Medical University of Havana, Havana, Havana, Cuba.
Background: Alzheimer's disease and related dementias (ADRD) disproportionately affect Latinos compared to non-Latino whites. Leveraging the non-monolithic structure of Latin America, which represents a large variability in social determinants of health (SDoH) and high levels of genetic admixture, we aimed to determine contributors to ADRD disparities within Latinos, focusing on genetic ancestry and SDoH.
Method: Community-dwelling participants aged 65 and older (n = 4000) from Cuba, Dominican Republic, Mexico, and Peru completed the 10/66 protocol assessments, including sociodemographic and risk factors questionnaire, neurological exam, cognitive assessment, and blood draw.
Alzheimers Dement

Neurogenetics Working Group, Universidad Científica del Sur, Lima, Peru.
Amerindian (AI) populations are substantially underrepresented in AD genetic studies. The Alzheimer's Disease Sequencing Project (ADSP), a global genetic initiative established by the National Institute of Aging (NIA) is supporting regional initiatives in Latin America and its admixed population. Latin America is the largest recently admixed population, with variable Native American, European, and African ancestry proportions, as result of successive settlements and new massive migrations.

December 2024
Rutgers-Robert Wood Johnson Medical School, New Brunswick, NJ, USA.
Background: South Asian (SA) Americans are underrepresented in US Alzheimer's disease and related dementias (ADRD) research. Despite sharing common languages, SA Americans differ from those in South Asia in education, health-related behaviors, and environmental exposures. NYC/NJ-area SA communities overwhelmingly revealed English-based neuropsychological testing preference given that many speak non-Hindi languages.
