RESUMEN
Background: Although the prevalence of conventional tobacco product use among U.S. college students has declined, an increasing number of students use various novel tobacco products. Objectives: This study aims to examine up-to-date sex and racial/ethnic patterns of tobacco use among students at a U.S. university in 2021-2023. Methods: Data of 2,732 students at an urban university in the Southeast of the U.S. were collected in 2021-2023 as part of the National College Health Assessment of the American College Health Association. Self-reported past 3-month use of five tobacco products (cigarette, electronic vapor products, water pipe/hookah, smokeless tobacco, and cigars) was dichotomized. We conducted multinomial logistic regression analysis to examine sex (male or female) and racial/ethnic (non-Hispanic White, non-Hispanic Black, Hispanic, or non-Hispanic Other) differences in single and dual/poly (con-current use of two or more tobacco products) tobacco use compared to nonuse, adjusting for age, student status, parent education level, obese status, psychological distress level, and survey year. Results: Male students had higher odds of being dual/poly tobacco user than female students, adjusting for covariates (adjusted odds ratio [AOR] = 2.00, 95% confidence interval [CI] = 1.42, 2.82). Non-Hispanic Black students had lower odds of being single (AOR = 0.43, 95% CI = 0.26, 0.69) and dual/poly (AOR = 0.09, 95% CI = 0.02, 0.37) tobacco user compared to non-Hispanic White students, adjusting for covariates. Conclusions: Considering higher health risk of con-current use of multiple tobacco products, dual/poly tobacco use prevention strategies targeting male and non-Hispanic White students may be considered.

OBJECTIVES: The Department of Defense reported that 344,030 cases of traumatic brain injury (TBI) were clinically confirmed from 2000 to 2015, with mild TBI (mTBI) accounting for 82.3% of all cases. Unfortunately, warfighters with TBI are often identified only when moderate or severe head injuries have occurred, leaving more subtle mTBI cases undiagnosed. This study aims to identify and validate an eye-movement visual test for screening acute mTBI. METHODS: Two-hundred active duty military personnel were recruited to perform the King-Devick® (KD) test. Subjects were equally divided into two groups: those with diagnosed acute mTBI (≤72h) and age-matched controls. The KD test was administered twice for test-retest reliability, and the outcome measure was total cumulative time to complete each test. RESULTS: The mTBI group had approximately 36% mean slower performance time with significant differences between the groups (p<0.001) in both tests. There were significant differences between the two KD test administrations in each group, however, a strong correlation was observed between each test administration. CONCLUSIONS: Significant differences in KD test performance were seen between the acute mTBI and control groups. The results suggest the KD test can be utilized for screening acute mTBI. A validated and rapidly administered mTBI screening test with results that are easily interpreted by providers is essential in making return-to-duty decisions in the injured warfighter.

The role of Epstein-Barr virus (EBV) in the pathogenesis of breast cancer is still unclear, although a growing body of evidence supports a link. The aim of this study was to investigate if EBV infection was more prevalent in invasive ductal carcinoma or invasive lobular carcinoma. An immunohistochemical marker for EBV (Epstein-Barr virus nuclear antigen 1 (EBNA1) clone E1-2.5) was applied to a tissue micro array section. The tissue micro array contained 80 cases of invasive ductal carcinoma, and 80 cases of invasive lobular carcinoma. Each case was scored as positive or negative for nuclear expression of EBNA1 in tumor cells using standard light microscopy. EBNA1 staining was evident in the tumor cells of 63 cases (39.4% of tumor cases). By tumor type (ductal/lobular) EBV infection was noted in 34 (42.5%) cases of invasive ductal carcinoma and 29 (36.2%) cases of invasive lobular carcinoma, this difference was not found to be significant (P=0.518). This study indicates that EBV infection is equally distributed across the ductal and lobular tumor types.
