    What does white privilege look like? This interactive session will allow audience members to voice their opinions of what it means to be White. While many White people do not have a clear understanding of their privilege, White privilege is prevalent in our everyday lives. This misunderstanding leads us towards systematic racism and to institutions where White Power is encouraged. This session will work towards helping audience members understand White privilege, gain an understanding of how white supremacy affects the perception of White privilege, and most importantly, what they should do with this privilege

    The nitrogen-vacancy center in diamond is a promising tool in oncology, electric field sensing, and quantum cryptography. High-pressure high-temperature (HPHT) nanodiamonds (NDs) are prime contenders for these fields because they host nitrogen-vacancy centers (NVCs) which are applicable towards cancer detection and electric and magnetic field sensing. However, to apply HPHT NDs to these fields, the surface must first be functionalized—a difficult process because of the inert nature of the surface. The project at hand focuses on surface modification of HPHT NDs with amines to allow for further bioconjugation of small molecules and plasmonic shells. This is done via liquid-phase chemistry and high-temperature gas-phase chemistry. To characterize the surface of aminated NDs, samples are probed using synchrotron radiation at the Stanford Synchrotron Radiation Lightsource (SSRL) alongside the transmission edge spectroscopy (TES) detector. Aminated NDs were characterized using X-ray photoelectric spectroscopy (XPS) and X-ray absorption spectroscopy (XAS) at SSRL. X-ray spectra are suggestive of multiple nitrogen moieties on the surface of the aminated NDs. With verification of a homogeneously amine-terminated surface, the NDs are prepared for further functionalization which can be targeted to enhance the properties of the NVC charge states for applications in enhanced electric field and voltage sensing

    Liver cancer occurs more frequently among Americans of Southeast Asian descent than any other group. This health disparity can be attributed to high rates of hepatitis B virus (HBV) infection. We examined HBV awareness, knowledge about HBV transmission, HBV testing levels, and HBV vaccination levels among Cambodian Americans

    Cambodian Americans have an elevated risk of liver cancer. This health disparity is attributable to high rates of hepatitis B virus (HBV) infection. Our study examined factors associated with HBV testing among Cambodian men and women. A population-based survey was conducted in the Seattle area. The Health Behavior Framework guided our survey instrument development. We attempted to interview a man and a woman in each household. The sample included 300 men and 367 women. About one-half of the male (45%) and female (54%) respondents had been tested for HBV. Two factors were independently associated with testing among men and women: a doctor had recommended testing and had asked a doctor for testing. Knowing that someone who looks and feels healthy can spread HBV was independently associated with testing among men. Low levels of HBV testing remain a public health problem among Cambodians. Interventions should improve patient-provider communication by encouraging providers who serve Cambodians to recommend HBV testing, as well as by empowering Cambodians to ask for testing

    Local molecular field theory for the treatment of electrostatics

    Full text link
    We examine in detail the theoretical underpinnings of previous successful applications of local molecular field (LMF) theory to charged systems. LMF theory generally accounts for the averaged effects of long-ranged components of the intermolecular interactions by using an effective or restructured external field. The derivation starts from the exact Yvon-Born-Green hierarchy and shows that the approximation can be very accurate when the interactions averaged over are slowly varying at characteristic nearest-neighbor distances. Application of LMF theory to Coulomb interactions alone allows for great simplifications of the governing equations. LMF theory then reduces to a single equation for a restructured electrostatic potential that satisfies Poisson's equation defined with a smoothed charge density. Because of this charge smoothing by a Gaussian of width sigma, this equation may be solved more simply than the detailed simulation geometry might suggest. Proper choice of the smoothing length sigma plays a major role in ensuring the accuracy of this approximation. We examine the results of a basic confinement of water between corrugated wall and justify the simple LMF equation used in a previous publication. We further generalize these results to confinements that include fixed charges in order to demonstrate the broader impact of charge smoothing by sigma. The slowly-varying part of the restructured electrostatic potential will be more symmetric than the local details of confinements.Comment: To be published in J Phys-Cond Matt; small misprint corrected in Eq.

    Approaches to use the WHO respiratory syncytial virus surveillance platform to estimate disease burden

    Get PDF
    The World Health Organization (WHO) recently completed the first phase of a RSV surveillance pilot study in fourteen countries (two to three in each WHO region) building on the Global Influenza Surveillance and Response System (GISRS). This active surveillance strategy had several objectives including understanding RSV-related health burden in a variety of settings. A range of approaches can be used to estimate disease burden; most approaches could not be applied by participating countries in the WHO surveillance pilot. This article provides the recommendations made by WHO for strengthening and expanding the scope of the RSV surveillance in the next phase to enable burden estimation

    Longitudinal Characterization of Atopic Dermatitis Phenotypes in The Children\u27s Respiratory and Environmental Workgroup (CREW) Birth Cohort Consortium

    Get PDF
    Rationale: Previously identified longitudinal patterns of atopic dermatitis (AD) may lack generalizability and precision due to small sample size and limited time points. We identify and describe longitudinal AD phenotypes in a large consortium study. Methods: Data from 11 birth cohorts across the United States from the CREW (Children’s Respiratory and Environmental Workgroup) consortium were harmonized to determine physician diagnosis of AD in each year of life from 0-7 years of age (N=7,900). AD phenotypes were identified using Longitudinal Latent Class Analysis, and relationships with demographic variables were determined using multinomial logistic regression with a 3-step procedure to account for uncertainty in class membership. Results: We identified 5 classes of AD expression, selected based on model fit, interpretability, and clinical utility: Persistent AD (15.4%), Early AD with Potential Reoccurrence (2.7%), Late-Onset AD (7.0%), Transient Early AD (3.0%), and Minimal/No AD (72.0%). Males had significantly higher odds of Persistent AD (OR [95% CI]=1.47 [1.22, 1.75]) and Early AD with Potential Reoccurrence (OR [95% CI]=1.89 [1.19, 2.94]). Relative to White children, Black children had higher odds of Persistent AD (OR [95% CI]=2.50 [2.05, 3.05]), Early AD with Potential Reoccurrence (OR [95% CI]=3.07 [1.94, 4.85]), and Transient Early AD (OR [95% CI]=4.12 [2.62, 6.48]). Conclusions: Five AD phenotypes exist in a diverse national sample of children. Black children and males are at increased risk of early and persistent AD. These findings illustrate potential risk factors to target AD prevention

    Rationale: Atopic dermatitis (AD) is a heterogenous inflammatory skin disease often associated with other allergic diseases. We characterized AD phenotypes and associated allergic outcomes longitudinally across a multi-site consortium. Methods: AD expression in 11 U.S. birth cohorts from the CREW (Children’s Respiratory and Environmental Workgroup) consortium was assessed in each year of life from age 0-7 years (N=7,900). Longitudinal Latent Class Analysis was performed to identify AD phenotypes. Five classes of AD were identified: Persistent AD (15.4%), Early AD with Potential Reoccurrence (2.7%), Late-Onset AD (7.0%), Transient Early AD (3.0%), and Minimal/No AD (72.0%). Serum allergen sensitization patterns and allergic clinical disease were associated with AD phenotype using multinomial logistic regression with a 3-step procedure to account for uncertainty in class membership. Results: Children with Persistent AD, Early AD with Potential Reoccurrence, and Transient Early AD were more likely to have food allergy compared to those with Minimal/No AD (OR[95% CI]=2.73[2.15, 3.45], 2.69[1.63, 4.45], 2.54[1.55, 4.16], respectively). These groups had similarly higher odds of food sensitization. Persistent AD (OR[95% CI]=1.81[1.48, 2.21]) and Early AD with Potential Reoccurrence (OR[95% CI]=3.66[1.90, 7.05]) had significantly higher odds of ever asthma relative to Minimal/No AD. At both 2-4 years and 5-7 years, persistent AD (OR[95% CI]=1.35[1.04, 1.74], 1.25[1.01, 1.53]) and Late-Onset AD (OR[95% CI]=1.68[1.13, 2.50], 2.22[1.33, 3.70]) relative to Minimal/No AD had higher odds of allergic rhinitis. Conclusions: Longitudinal AD phenotypes had varying associations with allergic sensitization, food allergy, asthma and allergic rhinitis, demonstrating the heterogeneity of allergic comorbidity risk associated with AD
