A racially and ethnically diverse health care workforce remains a distant goal, the attainment of which is contingent on inclusivity national medical student body. We examined diversity school applicants enrollees over past four decades with an eye toward assessing progress made. Data gender race or ethnic group in all doctorate degree-granting U.S. schools from 1978 through 2019 were examined. The percentage female doubled during this period, women now constitute more than half This upturn...
This study investigated if levels of allostatic load (ALoad) differed according to race/ethnicity in children and ALoad was associated with obesity-related measures.A multiethnic sample 307 aged seven 12 evaluated, composed 39% European American (EA), 35% African (AA), 26% Hispanic (HA) youth. Anthropometric measurements were evaluated by dual-energy X-ray absorptiometry, other included body mass index (BMI) waist circumference (WC). Allostatic scores estimated based on two different...
The role of vertical transmission in vectors has rarely been addressed the study dengue dynamics and control, part because it was not considered a critical population-level factor. In this paper, we apply pioneering modeling ideas Ross MacDonald, motivated by context 2000-2001 outbreak Peru, to assess multi-strain competition. An invading strain virus (DENV-2) from Asia rapidly circulated into Peru eventually displacing DENV-2 American. A host-dengue model that considers competing these two...
Abstract Variation in free-living microparasite survival can have a meaningful impact on the ecological dynamics of established and emerging infectious diseases. Nevertheless, resolving importance indirect environmental transmission ecology epidemics remains persistent challenge. It requires accurately measuring pathogens across reservoirs various kinds quantifying extent to which interaction between hosts generates new infections. These questions are especially salient for pathogens, where...
Background Limited data exist on transmission dynamics and effectiveness of control measures for influenza in confined settings. Objectives To investigate the a 2009 pandemic H1N1 A outbreak aboard Peruvian Navy ship quantify implemented measures. Methods We used surveillance simple stochastic epidemic model to characterize evaluate interventions during an ship. Results The serological attack rate was 49·1%, with younger cadets low‐ranking officers at greater risk infection than older,...
In this work, a two-strain dengue model with vertical transmission in the mosquito population is considered. Although often ignored models of fever, we show that effective control an outbreak can depend on whether or not significant mode disease transmission. We effect strategy aimed at reducing human-mosquito transmissions optimal framework. As likelihood increases, outbreaks become more difficult and expensive to control. However, even for low levels transmission, additional, uncontrolled,...
The role of free fatty acids (FFA) on Type 2 diabetes mellitus (T2DM) progression has been studied extensively with prior studies suggesting that individuals shared familial genetic predisposition to metabolic-related diseases may be vulnerable dysfunctional plasma FFA regulation. A harmful cycle arises when are not properly regulated by insulin contributing the development resistance, a key indicator for T2DM, since prolonged resistance lead hyperglycemia. We introduce hypothesis-driven...

Superspreaders (individuals with a high propensity for disease spread) have played pivotal role in recent emerging and re-emerging diseases. In outbreak studies, host heterogeneity based on demographic (e.g. age, sex, vaccination status) environmental climate, urban/rural residence, clinics) factors are critical the spread of infectious diseases, such as Ebola Middle East Respiratory Syndrome (MERS). Transmission rates can vary altered naturally or due to modified behaviors response...
A two-patch mathematical model of Dengue virus type 2 (DENV-2) that accounts for vectors’ vertical transmission and between patches human dispersal is introduced. Dispersal modelled via a Lagrangian approach. host-patch residence-times basic reproduction number derived conditions under which the disease dies out or persists are established. Analytical numerical results highlight role hosts’ in mitigating exacerbating dynamics. The framework used to explore dengue dynamics using, as starting...
Abstract Background The lipoprotein insulin resistance (LPIR) score was shown to predict (IR) and type 2 diabetes (T2D) in healthy adults. However, the molecular basis underlying LPIR utility for classification remains unclear. Objective To identify small molecule lipids associated with variation score, a weighted index of lipoproteins measured by nuclear magnetic resonance, Genetics Lipid Lowering Drugs Diet Network (GOLDN) study ( n = 980). Methods Linear mixed effects models were used...
The gut microbiota is associated with obesity and modulated by individual dietary components. However, the relationships between diet quality their potential interactions weight status in diverse populations are not well understood. This study examined associations overall quality, status, a racially balanced sample of adult females. Female participants (N=71) residing Birmingham, Alabama provided demographics, anthropometrics, biospecimens, data this observational from March 2014 to August...

Objective This study aimed to illustrate the use and value of measurement error models for reducing bias when evaluating associations between body fat having type 2 diabetes (T2D) or being physically active. Methods Logistic regression were used evaluate T2D physical activity among adults aged 19 80 years from Photobody Study ( n = 558). Self‐reported categorized as “yes” “no.” Body measured by two‐dimensional photographs was adjusted using dual‐energy x‐ray absorptiometry scans a reference....
Objective Assess caregivers’ knowledge about juice and sugar-sweetened beverages (SSBs) identify factors that contribute to their early introduction. Methods One hundred forty-four parents of young infants completed a 45-item questionnaire focused on infant nutrition. Results Seventy-two percent plan give babies starting in the first year life; only 16% introduce SSBs. Parents with some college education or more were significantly less likely report an intention ( P < .0001) SSBs .001)...
Abstract Background Deficits in knowledge and comfort related to pain management have been demonstrated adult hematology/oncology fellows. No such evaluation has undertaken pediatric (PHO) trainees. Procedure An IRB‐approved survey was administered PHO fellows throughout the United States (US) assess with opioid dosing, attitudes use of opioids, basic concepts including weight‐based incomplete cross‐tolerance, side effects. Results Email addresses were obtained for 132 from 37 programs....
Childhood obesity is a health emergency in many parts of the world including U.S. and, consequently, identifying local, regional or national intervention models capable, altering dynamics at scales that make difference remains challenge.
