Vitamin D Levels and SARS-CoV-2 Infection among Medically Underserved Populations in the Minority and Rural Coronavirus Insights Study.

Background: Extant literature presents contradictory findings on the role of vitamin D on SARS-CoV-2 infection. Our study included an examination of the relationship between vitamin D levels and SARS-CoV-2 infection among the Minority and Rural Coronavirus Insights Study (MRCIS) cohort, a diverse population of medically underserved persons presenting at five Federally qualified health centers in the United States.

Methods: We conducted a descriptive analysis to explore the relationship between vitamin D levels and SARS-CoV-2 infection among medically underserved participants.

Nucleocapsid and Spike Protein-Based Anti-SARS-CoV-2 Assay Performance in the Minority and Rural Coronavirus Insights Study: Characteristics of Socioeconomically Disadvantaged Populations with Health Disparities.

Background: COVID-19 has had a devastating impact on Black, Hispanic, and other underserved, disadvantaged populations. Here anti-SARS-CoV-2 tests are characterized in disadvantaged patients to examine equivalence in US populations.

Methods: Underserved participant adults (age > 18 years) were enrolled before the availability of SARS-CoV-2 vaccines in Federal Qualified Health Centers in California, Florida, Louisiana, Illinois, and Ohio and contributed samples to the Minority and Rural Coronavirus Insights Study (MRCIS).

The Minority and Rural Coronavirus Insights Study: Design and Baseline Characteristics of a Minority Cohort.

The Minority and Rural Coronavirus Insights Study (MRCIS) is an ongoing prospective cohort study examining health disparities associated with SARS-CoV-2 infection among medically underserved populations. This report describes procedures implemented to establish the MRCIS cohort and examines the factors associated with the molecular and serological assessment of SARS-CoV-2 infection status at participant enrollment. Participants were recruited from 5 geographically dispersed federally qualified health centers between November 2020 and April 2021.

Demographic Determinants and Geographical Variability of COVID-19 Vaccine Hesitancy in Underserved Communities: Cross-sectional Study.

Background: COVID-19 hospitalizations and deaths disproportionately affect underserved and minority populations, emphasizing that vaccine hesitancy can be an especially important public health risk factor in these populations.

Objective: This study aims to characterize COVID-19 vaccine hesitancy in underserved diverse populations.

Methods: The Minority and Rural Coronavirus Insights Study (MRCIS) recruited a convenience sample of adults (age≥18, N=3735) from federally qualified health centers (FQHCs) in California, the Midwest (Illinois/Ohio), Florida, and Louisiana and collected baseline data in November 2020-April 2021.

Low Density Infections and G6PD Deficiency Among Malaria Suspected Febrile Individuals in Ethiopia.

The identification and management of low parasitemia infections have become increasingly challenging for malaria control and elimination. Submicroscopic infections and G6PD deficiency among febrile patients require more sensitive diagnostic methods to improve detection and careful treatment regime of these infections. In Ethiopia, information on the low density submicroscopic malarial infections and frequency of G6PD deficiency (G6PDd) is scarce.

Associations between Place of Birth, Type of Attendant, and Small for Gestational Age Births among Pregnant non-Hispanic Black Medicaid Recipients.

Introduction: Although non-Hispanic Black women have increased risks of adverse birth outcomes compared with non-Hispanic white women in the United States, there is a lack of research specifically focusing on non-Hispanic Black women. Thus, this study's purpose was to evaluate whether place of birth and type of attendant used during labor is associated with having a newborn born small for gestational age (SGA) among non-Hispanic Black Medicaid recipients.

Methods: This study used 2017 Natality data from the National Vital Statistics System for non-Hispanic Black women who used Medicaid as a source of payment (N = 322,604).

Analysis of the Knockdown Resistance Locus (kdr) in Anopheles stephensi, An. arabiensis, and Culex pipiens s.l. for Insight Into the Evolution of Target-site Pyrethroid Resistance in Eastern Ethiopia.

The malaria vector, Anopheles stephensi, which is typically restricted to South Asia and the Middle East, was recently detected in the Horn of Africa. Addressing the spread of this vector could involve integrated vector control that considers the status of insecticide resistance of multiple vector species in the region. Previous reports indicate that the knockdown resistance mutations (kdr) in the voltage-gated sodium channel (vgsc) are absent in both pyrethroid-resistant and pyrethroid-sensitive An.

Sequence-based identification of Anopheles species in eastern Ethiopia.

Background: The recent finding of a typically non-African Anopheles species in eastern Ethiopia emphasizes the need for detailed species identification and characterization for effective malaria vector surveillance. Molecular approaches increase the accuracy and interoperability of vector surveillance data. To develop effective molecular assays for Anopheles identification, it is important to evaluate different genetic loci for the ability to characterize species and population level variation.
