RESUMEN

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.

RESUMEN

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.

RESUMEN

Men who sleep with men (MSM) and transgender individuals of color, the largest demographic in the House Ball community (HBC) are amongst the group at highest risk for HIV infection in the United States. The HBC have limited access to culturally appropriate HIV education. This study aimed to develop a partnership with HBC leaders to uncover strategies for increasing HIV prevention knowledge, including participation in HIV vaccine trials. To this end a research institution-community-HBC partnership was established. In-depth qualitative and quantitative data were collected from the 14 HBC leaders in western New York, revealing that knowledge of HIV and related vaccine trials was limited. Barriers to increasing HIV knowledge included fear of peer judgment, having inaccurate information about HIV, and lack of education. Among the HBC, community partnerships will further aid in the development of future HIV prevention programs and increase individuals' willingness to participate in future HIV vaccine trials.

RESUMEN

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.

RESUMEN

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.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The objective of this study was to compare complementary and alternative medicine (CAM) use in women with and without pelvic floor disorders (PFD). METHODS: We conducted a survey of women presenting to a specialty urogynecology (Urogyn) and gynecology (Gyn) clinic that examined demographic data, CAM use, and the presence of PFD (validated questionnaires). T tests, Fisher's exact tests, and logistic regression were used for analysis. To detect a 20% difference between groups, 234 Urogyn and 103 Gyn patients were needed. RESULTS: Participants included 234 Urogyn and 103 Gyn patients. Urogyn patients reported more CAM use than Gyn patients, even when controlled for differences between groups (51% vs. 32%, adjusted p = 0.006). Previous treatment (61% vs. 39%, adjusted p < 0.001) and increased number of PFD was associated with increased CAM use (adjusted p = 0.02). CONCLUSIONS: Women with PFD use CAM more frequently than women without PFD.

RESUMEN

Over half of human genome contains retroelements, including retrotransposons, retroviruses, and other elements. Human endogenous retroviruses (HERVs) comprise about 8% of human genome. The products of 2 of 16 identified genes of HERV-W seem to play a pivotal role in the placentation. These 2 genes are HERV-W env glycoprotein (syncytin-1) and HERV-FRD env glycoprotein (syncytin-2). It has been shown previously that syncytin-1 mediates cell-cell fusions of cytotrophoblasts into syncytiotrophoblasts. In addition, HERV-W env contains an immunosuppressive region that may prevent rejection of a semiallogenic fetus from the mother's immune system. We analyzed 40 full-term placental tissues to localize the expression of syncytin-1-ISR by immunohistochemical staining and by reverse trancscriptase (RT) in situ polymerase chain reaction (PCR). Both the immunostaining and in situ RT-PCR showed strong expression of syncytin-1 in the syncytiotrophoblast layer from the full-term placental tissues. To further analyze the mechanism of early embryo HERV-W env activation, we utilized a HTR-8/SVneo cell line developed from first trimester human trophoblasts and subjected them to various physiologic concentrations of maternal hormones. Quantitative RT-PCR analyses demonstrated that exposure to progesterone significantly upregulated the HERV-W env expression, whereas several other hormones apparently played lesser roles. In conclusion, our findings suggest that expression of syncytin-1 (HERV-W env) in utero is expressed exclusively in the syncytiotrophoblast layer and is upregulated by progesterone.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The objective of the study was to determine incidence, remission, and predictors of change in urinary incontinence in women ≥ 50 in a racially diverse population. METHODS: Subjects were women ≥ 50 with 4-year follow-up incontinence information in the Health and Retirement Study. Women with Any UI (AUI) and Severe UI (SVUI) were evaluated. Repeated measures logistic regression determined predictors of progression to and improvement of SVUI. RESULTS: Women (11,591) were evaluated. AUI 4-year cumulative incidence was 12.7-33.8% (fifth vs. ninth decades). SVUI incidence was lower but also increased with age. Among the predictors of improvement in SVUI were age (ninth vs. fifth decade odds ratios (OR) = 6.06) and ethnicity (Black vs. White OR = 0.57). Improvement of SVUI (45.8% overall) decreased with age (ninth vs. fifth decade OR = 0.12). CONCLUSIONS: SVUI incidence increased and remission decreased with age. Ethnicity and age predicted SVUI progression while age predicted improvement. Rates of the latter were high, particularly in younger patients.

RESUMEN

This case-control study was designed to identify risk factors for anal sphincter lacerations (ASL) in a multicultural population where episiotomies and operative vaginal deliveries are rarely performed. Cases were subjects with ASL delivered between July 1997 and June 2003. Two controls were selected for each case matched for gestational age. Independent variables collected included age, race/ethnicity, parity, tobacco use, medical conditions, episiotomy, operative vaginal delivery, epidural use, and infant weight. One thousand and sixty-six subjects met the inclusion criteria. The risk of ASL increased with increasing maternal age (Odds ratio [OR] 1.09 per year, 95% confidence interval [CI] 1.06, 1.12) and increasing infant weight (OR 1.09 per 100 g, 95% CI 1.06, 1.13). Multiparity was protective (P1 vs P2 OR 0.19, 95% CI 0.13, 0.28, and > or =P3 vs P1 OR 0.04, 95% CI 0.02, 0.11). Hispanic and Native American women were at increased risk for ASL (OR 2.08, 95% CI 1.41, 3.09 and OR 1.92, 95% CI 1.07, 3.45, respectively).

RESUMEN

OBJECTIVE: To evaluate whether treatment provided for ectopic pregnancies was different for patients with identified barriers to health care, including ethnicity, lack of insurance, distance from the treating facility that provides services and undocumented residency, at an institution that utilizes a protocol-based algorithm for treatment of ectopic pregnancies. STUDY DESIGN: Charts of 401 patients who were diagnosed with ectopic pregnancy from January 1, 1993, through December 31, 1998, were reviewed to compare the use of medical treatment using methotrexate versus surgical treatment. Data were analyzed with respect to patient ethnicity, socioeconomic status (including insurance status and possession of a social security card [a proxy for legal residency status]), residence inside or outside the county of the treating facility, patient presentation and treatment outcomes. RESULTS: There was no difference in treatment modality or success of primary treatment for ectopic pregnancies between groups regardless of ethnicity, health care insurance, residence outside the county the treating facility was located in or possession of a social security number. CONCLUSION: The treatment of ectopic pregnancies at the University of New Mexico Health Sciences Center is consistent across ethnic and socioeconomic populations. A well-designed treatment protocol may help provide evidenced-based, consistent treatment for patients requiring care who also have identified barriers to medical and surgical treatment.
