Background: Human papillomavirus (HPV) is the most common sexually transmitted infection and is associated with many types of cancers that disproportionately impact Hispanics. An HPV vaccine is available for individuals ages 9—45 that can prevent up to 90% of HPV-associated cancers. The current study investigates factors associated with accepting the HPV vaccine in a predominately Hispanic community. Methods: A cross-sectional study design with an online questionnaire was used to collect data from a community sample of adults between the ages 18–65 residing in a U.S./Mexico border city, El Paso, Texas. Theory-based factors (e.g., the Health Belief Model), culture-based factors (e.g., familism), and trusted sources of information were examined as predictors of HPV-vaccine acceptance (HPV-VA) and HPV-vaccine uptake (HPV-VU). Results: Community members (N = 602, M_age = 34.65, SD = 9.79) who were predominately Hispanic (89.4%) and female (79.6%) participated in the study. Linear regression models revealed that HPV-VA was associated with household size, primary language, engagement in organizational activities, health-related community stigma, government trust, and the HBM theory-based factors: perceived benefits, perceived harm, and perceived severity. Logistic regression analyses revealed that HPV-VU was associated with household size, engagement in non-organizational activities, HPV trusted sources of information, and perceived safety. Conclusions: Adequate HPV vaccination uptake among all vaccine-eligible Hispanics is an important step to lessen the HPV-attributed cancer burden. Our hypothesis that theory-based factors would be associated with HPV-VA and HPV-VU was supported. Our findings have implications for designing trusted, theory-based, and culturally sensitive health communications and interventions to promote vaccines in minority underrepresented communities.

While the cognitive enhancing effects of nicotine use have been well documented, it has also been shown to impair decision making. The goal of this study was to determine if exposure to nicotine vapor increases risky decision making. The study also aims to investigate possible long-term effects of nicotine vapor exposure on the expression of genes coding for cholinergic and dopaminergic receptors in brain. Thirty-two adult male Sprague Dawley rats were exposed to 24 mg/mL nicotine vapor or vehicle control, immediately followed by testing in the probability discounting task for 10 consecutive days. Fifty-four days after the 10-day vapor exposure, animals were sacrificed and expression of genes coding for the α4 and β2 cholinergic receptor subunits, and dopamine D1 and D2 receptors, were analyzed using RT-PCR. Exposure to nicotine vapor caused an immediate and transient increase in risky choice. Analyses of gene expression identified significant reductions in CHRNB2 and DRD1 in the nucleus accumbens core and CHRNB2 and DRD2 in the medial prefrontal cortex of rats previously exposed to nicotine vapor, relative to vehicle controls. Results provide data on the negative cognitive effects of nicotine vapor exposure and identify cholinergic and dopaminergic mechanisms that may affected with repeated use.

The Borderplex region has been profoundly impacted by the COVID-19 pandemic. Borderplex residents live in low socioeconomic (SES) neighborhoods and lack access to COVID-19 testing. The purpose of this study was two-fold: first, to implement a COVID-19 testing program in the Borderplex region to increase the number of residents tested for COVID-19, and second, to administer a community survey to identify trusted sources of COVID-19 information and factors associated with COVID-19 vaccine uptake. A total of 4071 community members were tested for COVID-19, and 502 participants completed the survey. COVID-19 testing resulted in 66.8% (n = 2718) positive cases. The community survey revealed that the most trusted sources of COVID-19 information were doctors or health care providers (67.7%), government websites (e.g., CDC, FDA, etc.) (41.8%), and the World Health Organization (37.8%). Logistic regression models revealed several statistically significant predictors of COVID-19 vaccine uptake such as having a trusted doctor or health care provider, perceiving the COVID-19 vaccine to be effective, and perceiving that the COVID-19 vaccine does not cause side-effects. Findings from the current study highlight the need for utilizing an integrated, multifactorial approach to increase COVID-19 testing and to identify factors associated with COVID-19 vaccine uptake in underserved communities.

The human papillomavirus (HPV) is the most common sexually transmitted infection in the United States, and the prevalence rate of infections is approximately 79 million. Research investigating HPV vaccine acceptability has primarily focused on female populations. The current study investigates factors associated with HPV vaccine acceptability in an underrepresented population within the literature, Hispanic males. Ninety-seven male participants ( M _age = 21.68 years; SD = 3.97) were recruited from a large urban university along the U.S./Mexico border to complete a 15- to 20-minute survey. More than half of the sample reported to have had a sexual experience within the past 12 months and a fifth of these participants reported that they never use protection such as condoms. Furthermore, about half of the sample reported that they did not receive the HPV vaccine or were unaware if they received the HPV vaccine. A strong correlation emerged between individual vaccine risk perceptions and family vaccine risk perceptions ( r = .82; p < .001). The following factors emerged as predictors of vaccine acceptability: having recommendations from health care providers, having a family with positive attitudes toward vaccines, and having a family that perceives less risks associated with vaccines. Implications of the findings are discussed.
