Youth Ambassadors Reaching Out (YARO): Lessons learned from the implementation of a youth-based cancer education program

We know that many factors contribute to the exacerbation of cancer health disparities. These inequities observed in adulthood may have originated from behaviors occurring in early adolescence. We believe that increasing awareness of cancer prevention in youth may help reduce future disparities. Our community partners identified a need for youth-oriented cancer prevention and helped design the pilot Youth Ambassadors Reaching Out (YARO) program. YARO provided cancer prevention and health disparities education and exposure to health careers to 73 middle school students between 2012-2016. YARO included didactic sessions (health disparities, smoking prevention, physical activity, nutrition), a cancer center tour, and Photovoice project. Students were encouraged to serve as ambassadors by sharing lessons learned with others. Participants demonstrated increases in cancer prevention knowledge during the program. Evaluation data revealed that students served as ambassadors by sharing information with others about healthy behaviors, improving their own health habits, and volunteering in their communities

Transcriptional down-regulation of ccr5 in a subset of HIV+ controllers and their family members.

HIV +Elite and Viremic controllers (EC/VCs) are able to control virus infection, perhaps because of host genetic determinants. We identified 16% (21 of 131) EC/VCs with CD4 +T cells with resistance specific to R5-tropic HIV, reversed after introduction of ccr5. R5 resistance was not observed in macrophages and depended upon the method of T cell activation. CD4 +T cells of these EC/VCs had lower ccr2 and ccr5 RNA levels, reduced CCR2 and CCR5 cell-surface expression, and decreased levels of secreted chemokines. T cells had no changes in chemokine receptor mRNA half-life but instead had lower levels of active transcription of ccr2 and ccr5, despite having more accessible chromatin by ATAC-seq. Other nearby genes were also down-regulated, over a region of ~500 kb on chromosome 3p21. This same R5 resistance phenotype was observed in family members of an index VC, also associated with ccr2/ccr5 down-regulation, suggesting that the phenotype is heritable

The content and context of physicians' communication with males about human papillomavirus vaccination

A physician's recommendation for human papillomavirus (HPV) vaccine is a key predictor of vaccine uptake; however, little is known about how physicians communicate about HPV vaccine with male patients. We sought to describe physicians' HPV vaccine communication practices with males who are of vaccine-eligible age (9-26 years). We surveyed representative samples of pediatric and family medicine physicians in Florida, and assessed whether physicians present HPV vaccine as optional or routine, and as a vaccine that prevents cancer. We also assessed the type of visit during which physicians discuss HPV vaccine with adolescent males and whether other healthcare providers in the practice discuss HPV vaccine or make the initial recommendation. We received 367 completed surveys (50.7% response rate). Few physicians (29.9%) reported they typically present HPV vaccine as routine to males ages 11-12 years, who constitute the target group for routine vaccination. When discussing HPV vaccination, many physicians reported somewhat or strongly emphasizing cancer prevention (80.0%). Physicians most often discussed HPV vaccine when they saw patients for well-child visits (93.0%) and least often at acute care visits (15.3%). Over half reported that at least one other healthcare professional in their practice discusses (56.1%) or makes the initial recommendation for (54.9%) HPV vaccination. Many physicians in our sample are presenting HPV vaccine as optional rather than routine and are missing opportunities to communicate with males about the vaccine. Our findings identify areas for future interventions to improve physicians' HPV vaccine communication and, ultimately, increase the use of this cancer-preventing vaccine

Health Literacy among Medically Underserved: The Role of Demographic Factors, Social Influence, and Religious Beliefs

The current study examined the sociodemographic and psychosocial variables that predicted being at risk for low health literacy among a population of racially and ethnically diverse patients accessing primary care services at community-based clinics. Participants (N = 416) were aged 50-75 years, currently not up-to-date with colorectal cancer (CRC) screening, at average CRC risk, and enrolled in a randomized controlled trial (RCT) aimed at promoting CRC screening. Participants completed a baseline interview that assessed health literacy as measured by Rapid Estimate of Adult Literacy in Medicine-Revised, sociodemographic factors, and psychosocial variables (e.g., health beliefs) prior to randomization and receipt of an intervention. Thirty-six percent of the participants were found to be at risk for low health literacy. Sociodemographic and psychosocial variables were assessed as predictors of being at risk for low health literacy using logistic regression. In the final model, predictors were male gender, being from a racial/ethnic minority group, being unable to work, having higher social influence scores, and having higher religious belief scores. These findings suggest several patient characteristics that may be associated with low health literacy, and highlight the importance of supporting all patients through simplified and clear communications and information to improve understanding of CRC screening information

Trajectories of Quality of Life after Hematopoietic Cell Transplantation: Secondary Analysis of BMT CTN 0902 Data

Quality of life is increasingly recognized as an important secondary endpoint of hematopoietic cell transplantation (HCT). The current study examined the extent to which attrition results in biased estimates of patient quality of life. The study also examined whether patients differ in terms of trajectories of quality of life in the first six months post-transplant. A secondary data analysis was conducted of 701 participants who enrolled in the Blood and Marrow Transplantation Clinical Trials Network (BMT CTN) 0902 trial. Participants completed the SF-36, a measure of quality of life, prior to transplant and 100 and 180 days post-transplant. Results indicated that attrition resulted in slightly biased overestimates of quality of life but the amount of overestimation remained stable over time. Patients could be grouped into three distinct classes based on physical quality of life: 1) low and stable; 2) average and declining, then stable; and 3) average and stable. Four classes of patients emerged for mental quality of life: 1) low and stable; 2) average, improving, then stable; 3) higher than average (by almost 1 SD) and stable; and 4) average and stable. Taken together, these data provide a more comprehensive understanding of quality of life that can be used to educate HCT recipients and their caregivers

Asymmetrically cut crystals as optical elements for highly collimated x‐ray beams

Asymmetrically cut perfect crystals, in both the Laue and Bragg geometries, are examined as single crystal monochromators for x‐ray beams that are collimated to a small fraction of the Darwin width, as is typical in experiments with coherent x rays. Both the Laue and asymmetric Bragg geometries are plagued by an inherent chromatic aberration that increases the beam divergence much beyond that of the symmetric Bragg geometry. Measurements from a recent experiment at the ESRF are presented to compare Si(220) (symmetric Bragg), diamond(111) (asymmetric Laue), and diamond(111) (symmetric Bragg inclined) geometries. © 1995 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70952/2/RSINAK-66-2-1506-1.pd

Missing the Target for Routine Human Papillomavirus Vaccination: Consistent and Strong Physician Recommendations Are Lacking for 11- to 12-Year-Old Males

Rates of routine human papillomavirus (HPV) vaccination of adolescent males in the U.S. are low. Leading health organizations advocate consistent and strong physician recommendations to improve HPV vaccine dissemination. This study describes the prevalence and correlates of consistent and strong physician recommendations for HPV vaccination of adolescent males

Florida physicians' reported use of AFIX-based strategies for human papillomavirus vaccination

HPV vaccination rates in Florida are low. To increase rates, the CDC recommends clinics adhere to components of their evidence-based quality improvement program, AFIX (Assessment, Feedback, Incentives, and eXchange of information). We explored factors associated with engaging in HPV-specific AFIX-related activities. In 2016, we conducted a cross-sectional survey of a representative sample of 770 pediatric and family medicine physicians in Florida and assessed vaccination practices, clinic characteristics, and HPV-related knowledge. Data were analyzed in 2017. The primary outcome was whether physicians' clinics engaged in ≥1 AFIX activity. We stratified by physician specialty and developed multivariable models using a backward selection approach. Of the participants in the analytic sample (n = 340), 52% were male, 60% were White of any ethnicity, and 55% were non-Hispanic. Pediatricians and family medicine physicians differed on: years practicing medicine (p < 0.001), HPV-related knowledge (p < 0.001), and VFC provider status (p < 0.001), among others. Only 39% of physicians reported engaging in ≥1 AFIX activity. In the stratified multivariable model for pediatricians, AFIX activity was significantly associated with HPV-related knowledge (aOR = 1.33;95%CI = 1.08–1.63) and provider use of vaccine reminder prompts (aOR = 3.61;95%CI = 1.02–12.77). For family medicine physicians, HPV-related knowledge was significant (aOR = 1.57;95%CI = 1.20–2.05) as was majority race of patient population (non-Hispanic White vs. Other: aOR = 3.02;95%CI = 1.08–8.43), daily patient load (<20 vs. 20–24: aOR = 9.05;95%CI = 2.72–30.10), and vaccine administration to male patients (aOR = 2.98;95%CI = 1.11–8.02). Fewer than half of Florida pediatric and family medicine physicians engaged in any AFIX activities. Future interventions to increase AFIX engagement should focus on implementing and evaluating AFIX activities in groups identified as having low engagement in AFIX activities

Efficacy of a Smoking Cessation Intervention for Survivors of Cervical Intraepithelial Neoplasia or Cervical Cancer: A Randomized Controlled Trial

PURPOSE: Women who smoke and have a history of cervical intraepithelial neoplasia (CIN) or cervical cancer represent a vulnerable subgroup at elevated risk for recurrence, poorer cancer treatment outcomes, and decreased quality of life. The purpose of this study was to evaluate the long-term efficacy of Motivation And Problem Solving (MAPS), a novel treatment well-suited to meeting the smoking cessation needs of this population. METHODS: Women who were with a history of CIN or cervical cancer, age 18 years and older, spoke English or Spanish, and reported current smoking (≥100 lifetime cigarettes plus any smoking in the past 30 days) were eligible. Participants (N = 202) were recruited in clinic in Oklahoma City and online nationally and randomly assigned to (1) standard treatment (ST) or (2) MAPS. ST consisted of repeated referrals to a tobacco cessation quitline, self-help materials, and combination nicotine replacement therapy (patch plus lozenge). MAPS comprised all ST components plus up to six proactive telephone counseling sessions over 12 months. Logistic regression and generalized estimating equations evaluated the intervention. The primary outcome was self-reported 7-day point prevalence abstinence from tobacco at 18 months, with abstinence at 3, 6, and 12 months and biochemically confirmed abstinence as secondary outcomes. RESULTS: There was no significant effect for MAPS over ST at 18 months (14.2% CONCLUSION: MAPS led to a greater than two-fold increase in smoking abstinence among survivors of CIN and cervical cancer at 12 months. At 18 months, abstinence in MAPS declined to match the control condition and the treatment effect was no longer significant
