Capacity building among african american faith leaders to promote HIV prevention and vaccine research.

BACKGROUND: In light of the increasing rates of HIV infection in African Americans, it is essential that black faith leaders become more proactive in the fight against the epidemic. The study aim was to engage faith leaders in a sustainable partnership to increase community participation in preventive HIV vaccine clinical research while improving their access to and utilization of HIV/AIDS prevention services. METHOD: Leadership Development Seminars were adapted for faith leaders in Rochester, NY, with topics ranging from the importance of preventive HIV vaccine research to social issues surrounding HIV/AIDs within a theological framework. Seminars were taught by field-specific experts from the black community and included the development of action plans to institute HIV preventive ministries. To assess the outcome of the Seminars, baseline and post-training surveys were administered and analyzed through paired sample t Tests and informal interviews. RESULTS: 19 faith leaders completed the intervention. In general, the majority of clergy felt that their understanding of HIV vaccine research and its goals had increased postintervention. A critical outcome was the subsequent formation of the Rochester Faith Collaborative by participating clergy seeking to sustain the collaborative and address the implementation of community action plans. CONCLUSION: Providing scientific HIV/AIDS knowledge within the context of clergy members' belief structure was an effective method for engaging black Church leaders in Rochester, NY. Collaborative efforts with various local institutions and community-based organizations were essential in building trust with the faith leaders, thereby building bridges for better understanding of HIV/AIDS prevention efforts, including HIV vaccine research.

Theoretical model of critical issues in informed consent in HIV vaccine trials.

The informed consent process (ICP) for HIV vaccine trials poses unique challenges and would benefit from improvements to its historically based structure and format. Here, we propose a theoretical framework that provides a basis for systematically evaluating and addressing these challenges. The proposed framework follows a linear pathway, starting with the precondition of voluntariness, three main variables of valid decision-making (competency, provision of information and understanding) and then the consequential outcome of either refusal or consent to participate. The existing literature reveals that culturally appropriate provision of information and resultant understanding by the vaccine trial participant are among the most significant factors influencing the authenticity of valid decision-making, though they may be overridden by other considerations, such as individual altruism, mistrust, and HIV-related stigma. Community collaborations to foster bidirectional transmission of information and more culturally tailored consenting materials, therefore, represent a key opportunity to enhance the ICP. By providing a visual synopsis of the issues most critical to IC effectiveness in a categorical and relational manner, the framework provided here presents HIV vaccine researchers a tool by which the ICP can be more systematically evaluated and consequently improved.

A community perspective on the role of fathers during pregnancy: a qualitative study.

BACKGROUND: Defining male involvement during pregnancy is essential for the development of future research and appropriate interventions to optimize services aiming to improve birth outcomes. STUDY AIM: To define male involvement during pregnancy and obtain community-based recommendations for interventions to improve male involvement during pregnancy. METHODS: We conducted focus groups with mothers and fathers from the National Healthy Start Association program in order to obtain detailed descriptions of male involvement activities, benefits, barriers, and proposed solutions for increasing male involvement during pregnancy. The majority of participants were African American parents. RESULTS: The involved "male" was identified as either the biological father, or, the current male partner of the pregnant woman. Both men and women described the ideal, involved father or male partner as present, accessible, available, understanding, willing to learn about the pregnancy process and eager to provide emotional, physical and financial support to the woman carrying the child. Women emphasized a sense of "togetherness" during the pregnancy. Suggestions included creating male-targeted prenatal programs, enhancing current interventions targeting females, and increasing healthcare providers' awareness of the importance of men's involvement during pregnancy. CONCLUSIONS: Individual, family, community, societal and policy factors play a role in barring or diminishing the involvement of fathers during pregnancy. Future research and interventions should target these factors and their interaction in order to increase fathers' involvement and thereby improve pregnancy outcomes.

Roles for the transcription elongation factor NusA in both DNA repair and damage tolerance pathways in Escherichia coli.

We report observations suggesting that the transcription elongation factor NusA promotes a previously unrecognized class of transcription-coupled repair (TCR) in addition to its previously proposed role in recruiting translesion synthesis (TLS) DNA polymerases to gaps encountered during transcription. Earlier, we reported that NusA physically and genetically interacts with the TLS DNA polymerase DinB (DNA pol IV). We find that Escherichia coli nusA11(ts) mutant strains, at the permissive temperature, are highly sensitive to nitrofurazone (NFZ) and 4-nitroquinolone-1-oxide but not to UV radiation. Gene expression profiling suggests that this sensitivity is unlikely to be due to an indirect effect on gene expression affecting a known DNA repair or damage tolerance pathway. We demonstrate that an N(2)-furfuryl-dG (N(2)-f-dG) lesion, a structural analog of the principal lesion generated by NFZ, blocks transcription by E. coli RNA polymerase (RNAP) when present in the transcribed strand, but not when present in the nontranscribed strand. Our genetic analysis suggests that NusA participates in a nucleotide excision repair (NER)-dependent process to promote NFZ resistance. We provide evidence that transcription plays a role in the repair of NFZ-induced lesions through the isolation of RNAP mutants that display altered ability to survive NFZ exposure. We propose that NusA participates in an alternative class of TCR involved in the identification and removal of a class of lesion, such as the N(2)-f-dG lesion, which are accurately and efficiently bypassed by DinB in addition to recruiting DinB for TLS at gaps encountered by RNAP.
