The History of Pathology in Texas

The History of Pathology in Texas is the study of the changes of disease in Texas from the frontier days to the 1990s. Marilyn Miller Baker wrote the book for the Texas Society of Pathologists. The book was published in 1996 with a forward by Vernie A. Stembridge, MD, the Ashbel Smith Professor and Chairman Emeritus of Pathology at the University of Texas Southwestern Medical Center at Dallas. The book covers the story of pathology from the "performance of crude autopsies" on the frontier through the emergence of bacteriology and immunology and beyond.

Safer sex choices among African-American college women

The purpose of this dissertation was to explore and describe the factors that influence the safer sex choices of African-American college women. The pandemic of HIV and the prevalence of other sexually transmitted diseases has disproportionately affected African-American females. As young women enter college they are faced with a myriad of choices. Unprotected sexual exploration is one choice that can lead to deadly consequences. This dissertation explores, through in-depth interviews, the factors associated with the decision to practice or not practice safe sex. ^ The first study describes the factors associated with increased sexual risk taking among African-American college women. Sexual risk taking or sex without a condom was found to be more likely when issues of self or partner pleasure were raised. Participants were also likely to have sexual intercourse without a condom if they desired a long term relationship with their partner. ^ The second study examined safe sex decision making processes among a group of African-American college women. Women were found to employ both emotional and philosophical strategies to determine their safe sex behavior. These strategies range from assessing a partner's physical capabilities and appearance to length of the dating relationship. ^ The third study explores the association between knowledge and risk perception as predictors for safer sex behaviors. Knowledge of HIV/AIDS and other STDs was not found to be a determinant of safer sex behavior. Perception of personal risk was also not highly correlated with consistent safer sex behavior. ^ These studies demonstrate the need for risk-based safer sex education and intervention programs. The current climate of knowledge-based program development insures that women will continue to predicate their decision to practice safer sex on their limited perception and understanding of the risks associated with unprotected sexual behavior. Further study into the emotional and philosophical determinants of sexual behavior is necessary for the realistic design of applicable and meaningful interventions. ^

The epidemiology of Hepatitis B and Hepatitis C virus infection among college students who are not US/Canadian born in Houston

Introduction. A vast majority of studies conducted in both developed and developing nations have focused on the epidemiology of HBV (Hepatitis B virus) and HCV (Hepatitis C virus) in high-risk populations; low-risk populations have been neglected. Recently Hwang et al conducted a unique large cross-sectional study in American university students that focused on cosmetic procedures and drug use for acquiring these infections among a low-risk young adult population In Houston. ^ Methods. This study is a secondary data analysis of the cross-sectional study conducted by Hwang et al. Data for this anonymous study were collected from 7,960 college students, among whom were the 2,561 non US/Canadian born students included in this study. All students completed a self-administered questionnaire and provided a blood sample. The epidemiology of HBV/HCV and risk factors for acquiring HBV/HCV infection was studied by comparing those with HBV/HCV infection versus those without. Both univariate and multivariate logistic regression was used to analyze the data. ^ Results. Overall prevalence of HBV and HCV infections were 22% and 0.8% respectively. By multivariable analysis, the factors that were independently associated with increased prevalence of HBV infection were increasing age per year (OR=1.06, 95% C.I=1.04-1.08), Black or Asian race (OR=6.21, 95% C.I=3.14-12.27), history of household contact with hepatitis (OR=1.87, 95% C.I=1.15-3.05), and having sexual partner with hepatitis (OR=5.20, 95% C.I=1.5-18.00). For HCV these factors included increasing age per year (OR= 1.08, 95% C.I=1.03-1.14), history of blood transfusion prior to 1991 (OR=25.45, 95% C.I=7.58-85.40), and Injection drug use. (OR=78.15, 95% C.I=12.19-500.85). Cosmetic procedures like tattooing were not significant risk factors for either HBV or HCV infection. ^ Conclusions. In a low-risk adult foreign born population, cosmetic procedures are not significant risk factors for HBV or HCV infection. The prevention strategies of these infections in this population should focus on safe sexual practices/abstinence and HBV vaccination should be provided to adolescents and sexually active adults. ^

The relationship between body image and physical activity in African American women

High rates of overweight and obesity in African American women have been attributed, in part, to poor health habits, such as physical inactivity, and cultural influences on body image perceptions. The purpose of this study was to determine the relationship among body mass index (BMI=kg/m2), body image perception (perceived and desired) and physical activity, both self-reported and objectively measured. Anthropometric measures of BMI and Pulvers' culturally relevant body image, physical activity and demographic data were collected from 249 African American women in Houston. Women ( M = 44.8 yrs, SD = 9.5) were educated (53% college graduates) and were overweight (M = 35.0 kg/m2, SD = 9.2). Less than half of women perceived their weight correctly regardless of their actual weight (p < 0.001). Nearly three-fourths (73.9%) of women who were normal weight desired to be obese, and only 39.4% of women desired to be normal weight, regardless of actual or perceived weight. Women in all weight classes (normal, overweight and obese) varied in objective measures of physical activity (F(2,112) = 4.424, p = .014). Regression analyses showed objectively measured physical activity was significantly associated with BMI ( Beta = -2.45, p < .01) and self-reported walking was significantly associated with perceived BMI (Beta = -.156, p = .017). Results suggest African American women who are smaller want to be larger and African American women who are larger want to be smaller, revealing dichotomous distortion in body images. Low rates of physical activity may be a factor. Research is needed to increase physical activity levels in African American women, leading to improved satisfaction with normal weight as desirable for health and beauty.

When Policy Opportunity is not Enough: College Access and Enrollment Patterns among Texas Percent Plan Eligible Students

In 1998, Texas initiated a bold new statewide university admission policy aimed at increasing college access for traditionally underserved students in the state. House Bill 588 (known as the Texas Top 10 Percent Plan (TTPP)) guaranteed automatic admission to the college or university of their choice for all top performing students in Texas public high schools. Fourteen years after the plan’s implementation, we see great strides and complexities in understanding student outcomes as a result of the percent plan. However, the legal controversy over the percent plan both in Texas and other states incorporating similar yet distinctly motivated alternative admissions plans continues to play out from institutional decision boards to the highest court in the nation. This study seeks to add to that discussion by exploring two questions. Descriptively, what are the admission and enrollment patterns within racial/ethnic groups of percent plan eligible students, over time, for Texas elite, emergent elite, and remaining public institutions? Given that all eligible percent plan students may enter the institution of choice in Texas, does which type of institution a TTPP student chooses relate to their race/ethnicity? The descriptive story told by the admission and enrollment distributions of equally eligible TTPP students is a complex but compelling one. Fundamentally, it identifies that statistically different application and enrollment patterns exist for Hispanic and especially African American TTPP beneficiaries relative to their White and Asian American counterparts.
