Little is known about the spatial clustering of neighborhood deprivation across United States (US). Using data from 2010 US Census Bureau, we created a index (NDI: higher NDI indicates deprivation/ lower socioeconomic status) for each county within County level scores were loaded into ArcGIS 10.5.1 where they mapped and analyzed using Moran's I Anselin Local I. Ultimately, varies spatially US. The highest found in Southeastern Southwestern states, inland regions Southern California. This...
Wearable mobile health (mHealth) technologies offer approaches for targeting physical activity (PA) in resource-limited, community-based interventions. We sought to explore user characteristics of PA tracking, wearable technology among a population within and needs assessment. In 2014–2015, we conducted the Washington, D.C., Cardiovascular Health Needs Assessment predominantly African-American churches communities with higher obesity rates lower household incomes. Participants received...
Chronic stress is associated with cardiovascular disease (CVD) risk and elevated amygdala activity.

Despite the widespread prevalence of cases associated with coronavirus disease 2019 (COVID-19) pandemic, little is known about spatial clustering COVID-19 in United States. Data on were used to identify U.S. counties that have both high and low incident proportions clusters. Our results suggest there are a variety sociodemographic variables severity county-level proportions. As pandemic evolved, communities color disproportionately impacted. Subsequently, it shifted from metropolitan areas...
Introduction A mixed-method, co-design approach to studying the adoption of mobile health (mHealth) technology among African-American (AA) women has not been fully explored. Qualitative data may contextualise existing knowledge surrounding perceptions mHealth AA as part formative work for designing a physical activity application (app). Methods convenience sample 16 completed an informatics survey prior participating in focus groups exploring their use and apps. Survey responses provided...
Background: Psychosocial stress correlates with cardiovascular (CV) events; however, associations between physiologic measures of stressors and CVD remain incompletely understood, especially in racial/ethnic minority populations resource-limited neighborhoods. We examined chronic stress-related neural activity, measured by amygdalar 18 Fluorodeoxyglucose ( FDG) uptake, aortic vascular FDG uptake (arterial inflammation measure) a community-based cohort. Methods: Forty participants from the...
Optimization of existing measurement tools is necessary to explore links between aspects the neighborhood built environment and health behaviors or outcomes. We evaluate a scoring method for virtual audits utilizing Active Neighborhood Checklist (the Checklist), audit measure, assess street segment representativeness in low-income neighborhoods. Eighty-two home neighborhoods Washington, D.C. Cardiovascular Health/Needs Assessment (NCT01927783) participants were audited using Google Street...
Objectives Little is understood about associations between neighborhood characteristics and depression, a cardiovascular disease (CVD) risk factor, in diverse populations. We examined relationships perceived/objective characteristics, CVD markers within the Washington, DC CV Health/Needs Assessment, an evaluation among predominantly African-American (AA) adults resource-limited communities.Method Factor analysis of overall environment perception (NEP) identified three NEP sub-scores:1)...
Neighborhoods and the microbiome are linked to cardiovascular disease (CVD), yet investigations identify microbiome-related factors at neighborhood levels have not been widely investigated. We sought explore relationships between deprivation index (NDI) microbial metabolite, trimethylamine-N-oxide. hypothesized that inflammatory markers dietary intake would be mediators of relationship.
Familial male-limited precocious puberty is a dominant autosomal genetic disease caused by activating LH receptor gene mutations, clinically expressed only in males. In preliminary studies, addition to the expected testosterone increase, we found high inhibin B levels before age of normal puberty.The objective study was assess cellular origin serum thanks testis section immunostaining.Serum testosterone, gonadotropin, B, pan-alphaC-inhibin, and anti-Mullerian hormone were measured....
Abstract Background Cardiovascular disease (CVD) is the leading cause of death in world. Given role immune cells atherosclerosis development and progression, effective methods for characterizing cell populations are needed, particularly among disproportionately at risk CVD. Results By using a variety antibodies combined one staining protocol, we were able to identify granulocyte, lymphocyte, monocyte sub-populations by CD-antigen expression from 500 µl whole blood, enabling more extensive...
A pressing need exists to understand and optimize the use of dietary assessment tools that can be used in community-based participatory research (CBPR) interventions. digital food record, which uses a mobile device capture intake through text photography inputs, is particularly promising method. However, little understood about acceptability feasibility records CBPR how best tailor needs community.
There is no established method for processing data from commercially available physical activity trackers. This study aims to develop a standardized approach defining valid wear time use in future interventions and analyses. Sixteen African American women (mean age = 62.1 years mean body mass index 35.5 kg/m2) wore the Fitbit Charge 2 20 days. Method 1 defined day as ≥10-hr with heart rate data. removed minutes without data, ≤ - SDs below ≤2 steps, nighttime. Linear regression modeled steps...
Context McCune–Albright syndrome (MAS) is a disorder caused by post-zygotic gain-of-function mutation in the gene encoding Gs-α protein. Sexual precocity, common girls, has been reported only 15% of boys, and little known on long-term evolution MAS males. Objective In boy with MAS, we studied spermatogenesis, testis histology, immunohistochemistry aim to shed light seminiferous tubule activity. Design A who presented at age 2.9 years sexual monolateral macroorchidism, increased testosterone...
Background: Cooking is an identified dietary strategy that positively associated with optimal diet quality. Prior to initiating cooking interventions, evaluating the prospective acceptability of intervention among community members living within low food access areas and understanding geospatial shopping locations may aid in designing community-tailored interventions. Methods: A sequential mixed methods study was conducted determine a planned community-located African American adults area at...
Neighborhood socioeconomic deprivation is associated with increased cardiovascular risk factors, including inflammation. Inflammation plays an important role in modifying the cardioprotective function of high-density lipoprotein (HDL). Moreover, recent studies suggest that very high HDL adverse disease (CVD) outcomes. Thus, we sought to explore relationships between neighborhood as a marker chronic stress, inflammation, proprotein convertase subtilisin/kexin type 9 (PCSK9) (a core component...
