The relationship between telomeres, nevi and melanoma is complex. Shorter telomeres have been found to be associated with many cancers and with number of nevi, a known risk factor for melanoma. However, shorter telomeres have also been found to decrease melanoma risk. We performed a systematic analysis of telomere-related genes and tagSNPs within these genes, in relation to the risk of melanoma, dysplastic nevi, and nevus count combining data from four studies conducted in Italy. In addition, we examined whether telomere length measured in peripheral blood leukocytes is related to the risk of melanoma, dysplastic nevi, number of nevi, or …

Process And Domain Specificity In Regions Engaged For Face Processing: An Fmri Study Of Perceptual Differentiation, Heather R. Collins, Xun Zhu, Ramesh S. Bhatt, Jonathan D. Clark, Jane E. Joseph

Psychology Faculty Publications

The degree to which face-specific brain regions are specialized for different kinds of perceptual processing is debated. This study parametrically varied demands on featural, first-order configural, or second-order configural processing of faces and houses in a perceptual matching task to determine the extent to which the process of perceptual differentiation was selective for faces regardless of processing type (domain-specific account), specialized for specific types of perceptual processing regardless of category (process-specific account), engaged in category-optimized processing (i.e., configural face processing or featural house processing), or reflected generalized perceptual differentiation (i.e., differentiation that crosses category and processing type boundaries). ROIs were …

CRVAW Faculty Journal Articles

BACKGROUND: Intimate partner violence (IPV) is prevalent among adolescent and adult women, with significant physical, sexual, and mental health consequences. In 2011, the Institute of Medicine's Clinical Preventive Services for Women consensus report recommended universal screening for violence as a component of women's preventive services; this policy has been adopted by the Health Resources and Services Administration (HRSA). These policy developments require that effective clinic-based interventions be identified, easily implemented, and taken to scale.

METHODS: To foster dialogue about implementing effective interventions, we convened a symposium entitled "Responding to Violence Against Women: Emerging Evidence, Implementation Science, and Innovative Interventions," on …

Racial Identity Attitudes, Perceived Barriers, Career Self-Efficacy, And Career Outcome Expectations Among African American Male Adolescents., Norman L. Townsel 1960-

Electronic Theses and Dissertations

Social Cognitive Career Theory (SCCT) holds that self-efficacy and outcome expectations are primary predictors of career choice goals and actions, with contextual influences moderating those choices and actions. Racial identity research indicates that African American adolescents perceive more barriers than their White counterparts. The current study hypothesized that chronological age, racial identity attitudes, and the perception of barriers would be significant influences on self-efficacy and outcome expectations for African American adolescents. The study explored the research question using two separate stepwise regression analyses. The first analysis explored racial identity attitudes, age, and perceived barriers in relation to self efficacy. The …

Risk Factors For Wound Complications After Ankle Fracture Surgery., Adam G Miller, Andrew Margules, Steven M Raikin

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: The overall rate of complications after ankle fracture fixation varies between 5% and 40% depending on the population investigated, and wound complications have been reported to occur in 1.4% to 18.8% of patients. Large studies have focused on complications in terms of readmission, but few studies have examined risk factors for wound-related issues in the outpatient setting in a large number of patients. A review was performed to identify risk factors for wound complications tracked in the hospital and outpatient setting.

METHODS: Four hundred and seventy-eight patients underwent open reduction and internal fixation of an ankle fracture between 2003 …

Multivitamin Supplementation In Hiv Infected Adults Initiating Antiretroviral Therapy In Uganda: The Protocol For A Randomized Double Blinded Placebo Controlled Efficacy Trial., David Guwatudde, Amara E. Ezeamama, Danstan Bagenda, Rachel Kyeyune, Fred Wabwire-Mangen, Henry Wamani, Ferdinand Mugusi, Donna Spiegelman, Molin Wang, Yukari C. Manabe, Wafaie W. Fawzi

Journal Articles: Epidemiology

BACKGROUND: Use of multivitamin supplements during the pre-HAART era has been found to reduce viral load, enhance immune response, and generally improve clinical outcomes among HIV-infected adults. However, immune reconstitution is incomplete and significant mortality and opportunistic infections occur in spite of HAART. There is insufficient research information on whether multivitamin supplementation may be beneficial as adjunct therapy for HIV-infected individuals taking HAART. We propose to evaluate the efficacy of a single recommended daily allowance (RDA) of micronutrients (including vitamins B-complex, C, and E) in slowing disease progression among HIV-infected adults receiving HAART in Uganda.

METHODS/DESIGN: We are using a …

FIU Electronic Theses and Dissertations

The current study was a cross-sectional examination of data collected during an HIV risk reduction intervention in south Florida. The purpose of the study was to explore the relationships between neighborhood stress, parenting, attitudes, and adolescent sexual intentions and behavior. The Theory of Planned Behavior was used as a model to guide variable selection and propose an interaction pathway between predictors and outcomes.

Potential predictor variables measured for adolescents ages 13-18 (n=196) included communication about sex, parent-family connectedness, parental presence, parent-adolescent activity participation, attitudes about sex and condom use, neighborhood disorder, and exposure to violence. Outcomes were behavioral intentions and …

Association Of Intimate Partner Violence And Childhood Sexual Abuse With Cancer-Related Well-Being In Women, Ann L. Coker, Diane R. Follingstad, Lisandra S. Garcia, Corrine M. Williams, Timothy N. Crawford, Heather M. Bush

Obstetrics and Gynecology Faculty Publications

BACKGROUND: Limited evidence suggests that intimate partner violence (IPV) may be associated with poorer cancer outcomes. We hypothesized that timing and type of IPV as well as childhood sexual abuse (CSA) may negatively affect depression, perceived stress, and cancer-related well-being.

METHODS: This was a cross-sectional study of women diagnosed with either breast, cervical, or colorectal cancer in the prior 12 months included in the Kentucky Cancer Registry. Consenting women were interviewed by phone (n=553). Multivariate analysis of covariance (MANCOVA) was used to determine the association between IPV (37% lifetime prevalence) and type, timing, and the range of correlated cancer-related well-being …

Parental Influence On Inhalant Use, Alina Baltazar, Gary Hopkins, Duane C. Mcbride, Curtis J. Vanderwaal Dr., Sara Pepper, Sarah Mackey

Faculty Publications

The purpose of this article is to examine the dynamics of the relationship between parents and their adolescent children and their association with lifetime and past-month inhalant usage. The population studied was seventh- through ninth-grade students in rural Idaho (N = 570). The authors found a small, but consistent, significant inverse correlation between parental bonding and monitoring of behavior and inhalant usage. There was also a significant positive correlation between verbally aggressive behavior in the family and inhalant use. The data imply that family interaction may play a significant role in the use of inhalants and that the family can …

Construct-Validity Of The Engagement With Challenge Measure For Adolescents: Structural- And Criterion-Validity Evidence, E. Whitney G. Moore, David Hansen

Kinesiology, Health and Sport Studies

For adolescents, engaging with challenge is a key developmental task, hypothesized to support development of adult-like competencies (e.g., agency and self-direction; Larson, 2000). This study aimed to assess the construct-validity (structural- and concurrent-validity) of a new self-report measure assessing adolescents’ engagement with challenge to help researchers understand how different settings and the conditions in these settings support adolescents’ development. The sample consisted of 337 adolescents in 10 FFA programs along with the adult advisors in each program. Adolescents completed a questionnaire, which included the Engagement with Challenge measure and the following criterion variables: number of contests completed, participation frequency, and …

Expanding The Basic Science Debate: The Role Of Physics Knowledge In Interpreting Clinical Findings., Mark Goldszmidt, John Paul Minda, Sarah L Devantier, Aimee L Skye, Nicole N Woods

Brain and Mind Institute Researchers' Publications

Current research suggests a role for biomedical knowledge in learning and retaining concepts related to medical diagnosis. However, learning may be influenced by other, non-biomedical knowledge. We explored this idea using an experimental design and examined the effects of causal knowledge on the learning, retention, and interpretation of medical information. Participants studied a handout about several respiratory disorders and how to interpret respiratory exam findings. The control group received the information in standard "textbook" format and the experimental group was presented with the same information as well as a causal explanation about how sound travels through lungs in both the …

Rice Consumption And Urinary Arsenic Concentrations In U.S. Children, Matthew A. Davis, Todd A. Mackenzie, Kathryn L. Cottingham, Diane Gilbert-Diamond, Tracy Punshon, Margaret R. Karagas

Dartmouth Scholarship

Background: In adult populations, emerging evidence indicates that humans are exposed to arsenic by ingestion of contaminated foods such as rice, grains, and juice; yet little is known about arsenic exposure among children.

Objectives: Our goal was to determine whether rice consumption contributes to arsenic exposure in U.S. children.

Methods: We used data from the nationally representative National Health and Nutrition Examination Survey (NHANES) to examine the relationship between rice consumption (measured in 0.25 cups of cooked rice per day) over a 24-hr period and subsequent urinary arsenic concentration among the 2,323 children (6–17 years of age) who participated in …

The Differential Effects Of Maternal Age, Race/Ethnicity And Insurance On Neonatal Intensive Care Unit Admission Rates., Beatriz E De Jongh, Robert Locke, David A Paul, Matthew Hoffman

Department of Pediatrics Faculty Papers

BACKGROUND: Maternal race/ethnicity, age, and socioeconomic status (SES) are important factors determining birth outcome. Previous studies have demonstrated that, teenagers, and mothers with advanced maternal age (AMA), and Black/Non-Hispanic race/ethnicity can independently increase the risk for a poor pregnancy outcome. Similarly, public insurance has been associated with suboptimal health outcomes. The interaction and impact on the risk of a pregnancy resulting in a NICU admission has not been studied. Our aim was, to analyze the simultaneous interactions of teen/advanced maternal age (AMA), race/ethnicity and socioeconomic status on the odds of NICU admission.

METHODS: The Consortium of Safe Labor Database (subset …

Division of Internal Medicine Faculty Papers & Presentations

OBJECTIVE: To determine if interindividual differences in plasma concentrations of 25-hydroxyvitamin D(3) (25(OH)D(3)) have pathophysiologic significance, we evaluated a cohort of female monkeys, seeking to identify associations with clinically relevant cardiovascular risk factors, including age, abdominal obesity (waist circumference), and high-density lipoprotein cholesterol (HDL-C).

METHODS: One hundred fifty-five female vervet monkeys (Chlorocebus aethiops sabaeus) aged 3-25 years consumed a typical western diet for 7-8 weeks that provided a woman's equivalent of approximately 1000 IU/day of vitamin D(3). Measurements of vitamin D(3) and HDL-C concentrations, as well as waist circumference, were obtained.

RESULTS: Among young monkeys (aged 3-5 years), compared to …

Marijuana Use Development Over The Course Of Adolescence Among North American Indigenous Youth, Jacob E. Cheadle, Kelley J. Sittner Hartshorn

Department of Sociology: Faculty Publications

This study investigated the links between marijuana use trajectories and marijuana abuse/ dependence (DSM-IV) using five waves of data from 718 North American Indigenous adolescents between 10 and 17 years from eight reservations sharing a common language and culture. Growth mixture models indicated that 15% of youth began using by 11–12 years of age and that another 20% began shortly thereafter. These early users had odds of abuse/dependence 6.5 times larger than abstainers. Girls were also unexpectedly found to be particularly at risk of early use, and this did not reflect other background and psychosocial factors, including friend use. While …

A Clinically Significant Interaction Between Tacrolimus And Multiple Proton Pump Inhibitors In A Kidney Transplant Recipient, Michelle Maguire, Thaddeus T. Franz, David S. Hains

Pharmacy Practice Faculty Publications

The shared metabolism of PPIs and tacrolimus through the CYP enzyme system has been associated with clinically significant drug interactions, especially in patients who are classified as CYP 2C19 PMs. However, existing data are conflicting, indicating that a single mechanism does not account for all interactions. A drug interaction between tacrolimus and omeprazole, esomeprazole, but not lansoprazole, occurred in an 18-yr-old female kidney transplant recipient classified as a CYP 2C19 extensive (normal) metabolizer. This case suggests that further research is needed to establish the definitive mechanism of this potentially serious drug–drug interaction. Physicians prescribing PPIs in organ transplant recipients with …

Pediatrics Faculty Publications

A total of 231 schools participated in the Project P.A.T.H.S. in 2009/2010 school year. After completion of the Tier 1 Program, subjective outcome evaluation data were collected from 3,259 program implementers. Based on the consolidated data with schools as units, results showed that participants had positive perceptions of the program, implementers, and benefits of the program. More than four-fifth of the implementers regarded the program as helpful to the program participants. Multiple regression analyses revealed that perceived qualities of the program and the program implementers predicted perceived effectiveness of the program. Similar to previous studies, compared to implementers' perception about …

Family And Personal Adjustment Of Economically Disadvantaged Chinese Adolescents In Hong Kong, Daniel T. L. Shek, Pik Fong Tsui

Pediatrics Faculty Publications

This study attempted to examine the relationship between poverty and adolescent developmental outcomes in the family and personal domains in 3,328 Chinese secondary school students in Hong Kong. Developmental outcomes included positive youth development constructs, problem behaviors, perceived family interaction, and parental parenting. Results showed that adolescents experiencing poverty did not differ from nonpoor adolescents in terms of risk behavior and in most indicators of positive youth development. On the other hand, adolescents with economic disadvantage displayed lower levels of positive identity, family interaction, and perceived paternal parenting than did those without economic disadvantage.
