Abstract
Background The Healthy Men, Health Communities program aims to improve preventive behaviors among African American men to reduce HPV-related cancer disparities. Purpose We describe the development of an educational intervention using cultural-targeting strategies (i.e., linguistics, peripherals, evidence, socio-culture, and constituent-involving). Methods After building capacity of community-based organization (CBO) leaders as research team members, we conducted 3 focus groups, 30 surveys, and a community review and program evaluation with African American men. Results Focus group themes were: 1) The Known and Unknown of Cancer, HPV, and the vaccine; (2) Personal experiences with cancer were commonplace; (3) Barriers to Engaging HPV Cancer Preventive Behaviors; (4) Multi-Modal Strategies are needed to improve preventive behaviors; and (5) Actual versus Preferred Sources of Information. Survey data indicated men desired information on penile (52%) and oral cancers (48%). The preferred education format was a summit with speakers on various topics (96%). Post-summit evaluation indicated majority of males intended to get screened (73%), eat healthier (77%), and exercise more (64%). About 40% reported getting themselves, children, or grandchildren the HPV vaccine. Discussion Our program demonstrated acceptability, feasibility, and preliminary efficacy. This work warrants further study as a potential program to improve HPV preventive behaviors among African American men.

Abstract
AIM Culturally-appropriate, educational programs are recommended to improve cancer clinical trial participation among African Americans and Latinos. This study investigated the effect of a culturally-appropriate, educational program on knowledge, trust in medical researchers, and intent for clinical trial participation among African Americans and Latinos in Middle Tennessee. METHOD Trained community health educators delivered a 30-min presentation with video testimonials to 198 participants in 13 town halls. A pre-post survey design was used to evaluate the intervention among 102 participants who completed both pre- and post-surveys one to two weeks after the session. RESULTS Paired-sample t-test showed significant increases in unadjusted mean scores for knowledge (p < 0.001), trust in medical researchers (p < 0.001), and willingness to participate in clinical trials (p = 0.003) after the town halls in the overall sample. After adjusting for gender and education, all three outcomes remained significant for the overall sample (knowledge: p < 0.001; trust in medical researchers: p < 0.001; willingness: p = 0.001) and for African Americans (knowledge: p < 0.001; trust in medical researchers: p = 0.007; willingness: p = 0.005). However, willingness to participate was no longer significant for Latinos (knowledge: p < 0.001; trust in medical researchers: p = 0.034; willingness: p = 0.084). CONCLUSIONS The culturally-appropriate, educational program showed promising results for short-term, clinical trial outcomes. Further studies should examine efficacy to improve research participation outcomes.

Abstract
BACKGROUND Dissemination of research findings to past study participants and the community-at-large is important. Yet, a standardized process for research dissemination is needed to report results to the community. OBJECTIVE We developed a framework and strategies to guide community-academic partnerships in community-targeted, dissemination efforts. METHODS From 2017 to 2019, a community-academic partnership was formed in Nashville, Tennessee, and iteratively developed a framework and strategies for research dissemination using cognitive interviews. A deductive, constant comparative analysis was conducted on interview responses to examine framework and strategy content. Feedback was used to finalize the framework and strategies for the evaluation. Using existing data, the framework's utility was evaluated in seven town hall meetings (n = 117). Bivariate analyses determined its effect on community members' trust and willingness to participate in research using pre- and post-surveys. Evaluation results were used to finalize the framework. RESULTS The Community-Engaged Research Dissemination (CERD) framework has two phases. Phase one is a preliminary planning phase with two steps, and phase two is the four-step dissemination process. There are five standards to be upheld conducting these phases. We provide competencies for each component. Three feasible, culturally adapted strategies were developed as exemplars to disseminate research findings. Using pre- and post-surveys for intervention evaluation, there was a significant difference in trust in medical research and researchers (P = .006) and willingness to participate in research (P = .013). DISCUSSION AND CONCLUSION The CERD framework can potentially standardize the process and compare the effect of dissemination efforts on the community's trust and willingness to participate in research.

Abstract
Background Addressing knowledge deficiencies about cancer clinical trials and biospecimen donation can potentially improve participation among racial and ethnic minorities. This paper describes the formative research process used to design a culturally-appropriate cancer clinical trials education program for African American and Latino communities. We characterized community member feedback and its integration into the program. Methods We incorporated three engagement approaches into the formative research process to iteratively develop the program: including community-based organization (CBO) leaders as research team members, conducting focus groups and cognitive interviews with community members as reviewers/consultants, and interacting with two community advisory groups. An iterative-deductive approach was used to analyze focus group data. Qualitative data from advisory groups and community members were compiled and used to finalize the program. Results Focus group themes were: 1) Community Perspectives on Overall Presentation; 2) Community Opinions and Questions on the Content of the Presentation; 3) Culturally Specific Issues to Participation in Cancer Clinical Trials; 4) Barriers to Clinical Trial Participation; and 5) Perspectives of Community Health Educators. Feedback was documented during reviews by scientific experts and community members with suggestions to ensure cultural appropriateness using peripheral, evidential, linguistic, sociocultural strategies, and constituent-involving. The final program consisted of two versions (English and Spanish) of a culturally-appropriate slide presentation with speaker notes and videos representing community member and researcher testimonials. Conclusions Incorporating multiple community engagement approaches into formative research processes can facilitate the inclusion of multiple community perspectives and enhance the cultural-appropriateness of the programs designed to promote cancer clinical trial participation among African Americans and Latinos.

Abstract
Background Germline mutations in the BRCA1 and BRCA2 genes account for 20–25 % of inherited breast cancers and about 10 % of all breast cancer cases. Detection of BRCA mutation carriers can lead to therapeutic interventions such as mastectomy, oophorectomy, hormonal prevention therapy, improved screening, and targeted therapies such as PARP-inhibition. We estimate that African Americans and Hispanics are 4–5 times less likely to receive BRCA screening, despite having similar mutation frequencies as non-Jewish Caucasians, who have higher breast cancer mortality. To begin addressing this health disparity, we initiated a nationwide trial of BRCA testing of Latin American women with breast cancer. Patients were recruited through community organizations, clinics, public events, and by mail and Internet. Subjects completed the consent process and questionnaire, and provided a saliva sample by mail or in person. DNA from 120 subjects was used to sequence the entirety of BRCA1 and BRCA2 coding regions and splice sites, and validate pathogenic mutations, with a total material cost of $85/subject. Subjects ranged in age from 23 to 81 years (mean age, 51 years), 6 % had bilateral disease, 57 % were ER/PR+, 23 % HER2+, and 17 % had triple-negative disease. Results A total of seven different predicted deleterious mutations were identified, one newly described and the rest rare. In addition, four variants of unknown effect were found. Conclusions Application of this strategy on a larger scale could lead to improved cancer care of minority and underserved populations.

Abstract
Abnormalities in dopaminergic control of basal ganglia function play a key role in Parkinson's disease. Adenosine appears to modulate the dopaminergic control in striatum, where an inhibitory interaction between adenosine and dopamine receptors has been demonstrated. However the interaction has not been established in substantia nigra pars reticulata (SNr) where density of both receptors is high. Here we have explored the interaction between A1/D1 receptors in SNr. In SNr slices, SKF 38393, a selective D1 receptor agonist, produced a stimulation of depolarization-induced Ca(2+)-dependent [(3)H]GABA release that was inhibited by adenosine. The adenosine inhibition was abolished by 8-cyclopentyl-1,3-dipropylxanthine (DPCPX), a selective adenosine A1 receptor antagonist. DPCPX per se enhanced GABA release, indicating inhibition of the release by endogenous adenosine. When D1 receptors were blocked with SCH 23390 or the slices were depleted of dopamine, the effect of DPCPX was suppressed, showing that activation of dopamine receptors was necessary for the adenosine inhibition. In normal slices, 2-chloro-n(6)-cyclopentyladenosine (CCPA), a selective A1 agonist, inhibited GABA release, but the inhibition was prevented by the blockade of D1 receptors with SCH 23390. Superperfusion with 8-bromo-cAMP produced a stimulation of GABA release that was not blocked by CCPA: this finding indicates that the blockade of D1 effects caused by activation of A1 receptors is specific. To see if these actions on GABA release were correlated with changes in motor behavior we studied the effect of unilateral intranigral injections of modifiers of adenosine A1 and dopamine D1 receptors in rats challenged with systemic methamphetamine. Both the A1 agonist CCPA and the D1 antagonist SCH 23390 produced ipsilateral turning whereas the A1 antagonist DPCPX caused contralateral turning. These motor effects are consistent with the findings on GABA release. The results indicate the presence of an inhibitory A1/D1 receptor interaction in SNr. The inhibition exerted by A1 adenosine receptors on GABAergic striatonigral transmission would be due exclusively to blockade of the facilitation resulting from activation of D1 dopamine receptors. The data permit to better understand the action of adenosine antagonists in the treatment of Parkinson's disease.

Abstract
BACKGROUND Since 1993 the Pan American Health Organization has coordinated a surveillance network with the National Reference Laboratories of Argentina, Brazil, Chile, Colombia, Mexico and Uruguay aimed at monitoring capsular types and antimicrobial susceptibility of Streptococcus pneumoniae causing invasive disease in children <6 years of age. METHODS The surveillance system included children 6 years of age and younger with invasive disease caused by S. pneumoniae. The identification, capsular typing and susceptibility to penicillin of the isolates were conducted using a common protocol, based on standard methodologies. RESULTS By June, 1999, 4,105 invasive pneumococcal isolates had been collected mainly from pneumonia (44.1%) and meningitis (41.1%) cases. Thirteen capsular types accounting for 86.1% of the isolates (14, 6A/6B, 5, 1, 23F, 19F, 18C, 19A, 9V, 7F, 3, 9N and 4) remained the most common types during the surveillance period. Diminished susceptibility to penicillin was detected in 28.6% of the isolates, 17.3% with intermediate and 11.3% with high level resistance. Resistance varied among countries and increased during this period in Argentina, Colombia and Uruguay. Serotypes 14 and 23F accounted for 66.6% of the resistance. CONCLUSION These surveillance data clearly demonstrate the potential impact of the introduction of a conjugate vaccine on pneumococcal disease and the need for more judicious use of antibiotics to slow or reverse the development of antimicrobial resistance.
