Background checks are designed to prevent firearm acquisition by people prohibited from purchasing or possessing firearms. There is limited information about background checks, particularly on a state by state basis. We conducted a state-representative, probability-based, Internet survey of California adults in 2018 (n=2558; completion rate 49%) to describe where, when, and how firearms are acquired and to estimate the proportion of current firearm owners who purchased their most recent firearm without a background check. ⋯ Overall, firearm purchases without background checks are considerably less common in California than in states without regulations on private sales. However, gaps in implementation and proper enforcement remain. Future research could investigate reasons for such lapses, as well as complementary state policy approaches that require background checks prior to point of purchase.

Randomized Controlled TrialComputer-tailored intervention increases colorectal cancer screening among low-income African Americans in primary care: Results of a randomized trial.
Although African Americans have the highest colorectal cancer (CRC) incidence and mortality rates of any racial group, their screening rates remain low. ⋯ This one-time computer-tailored intervention significantly improved CRC screening rates among low-income African American patients. This finding was largely driven by increasing SBT but the impact of the intervention on colonoscopy screening was strong. Implementation of a CRC screening quality improvement program in the VA site that included provision of stool blood test kits and follow-up likely contributed to the strong intervention effect observed at that site. The trial is registered at ClinicalTrials.gov as NCT00672828.

Randomized Controlled TrialEffects of fact-checking social media vaccine misinformation on attitudes toward vaccines.
Social media vaccine misinformation can negatively influence vaccine attitudes. It is urgent to develop communication approaches to reduce the misinformation's impact. This study aimed to test the effects of fact-checking labels for misinformation on attitudes toward vaccines. ⋯ Exposure to fact-checking labels on misinformation can generate more positive attitudes toward vaccines in comparison to exposure to misinformation. Incorporating labels from trusted universities and health institutions on social media platforms is a promising direction for addressing the vaccine misinformation problem. This points to the necessity for closer collaboration between public health and research institutions and social media companies to join efforts in addressing the current misinformation threat.

Sexually transmitted disease clinics in the United States: Understanding the needs of patients and the capabilities of providers.
Reports of bacterial sexually transmitted infections are at the highest levels ever reported in the United States, and state and local budgetary issues are placing specialized sexually transmitted disease (STD) care at risk. This study collected information from 4138 patients seeking care at 26 STD clinics in large metropolitan areas across the United States with high levels of reported STDs to determine patient needs and clinic capabilities. Surveys were provided to patients attending these STD clinics to assess their demographic information as well as reasons for coming to the clinic and surveys were also provided to clinic administrators to determine their operational capacities and services provided by the clinic. ⋯ Patients attending STD clinics across the country indicated that they do so because of the relative ease of getting an appointment; including walk-in and same-day appointments as well as the welcoming environment and expertise of the staff at the clinic. Additionally, STD clinics provide specialized care to patients; including HIV testing and counseling as well as on-site, injectable medications for the treatment of gonorrhea and syphilis in an environment that helps to reduce the role of stigma in seeking this kind of care. Sexually transmitted disease clinics continue to play an important role in helping to curb the rising epidemic of sexually transmitted infections.

Adolescent perceptions of E-cigarette use and vaping behavior before and after the EVALI outbreak.
This study sought to determine whether adolescents' e-cigarette risk perceptions, perceived benefits, and positive expectations, and vaping behavior changed after the electronic-cigarette or vaping product use-associated lung injury (EVALI) outbreak. This longitudinal survey studied 1539 high school students in suburban Philadelphia, PA in 11th and 12th grade, before and after the outbreak of EVALI cases in 2019. Adolescents who reported current nicotine vaping at baseline (versus those who did not) had a greater increase in risk perceptions (B = -0.31, p = 0.04) and a greater decrease in positive expectations (B = -1.30, p = 0.003) at follow-up. ⋯ Perceptions of the risks of e-cigarette use increased and positive expectations of e-cigarette use decreased after the EVALI outbreak. Adolescent risk perceptions and positive expectations of e-cigarette use are two potential targets to impact vaping behavior. Emphasizing the risks of e-cigarette use while decreasing positive expectations of use have the potential to reduce vaping behavior, and perhaps subsequent EVALI cases.
