Relationship between serostatus disclosure and categories of HIV transmission risk in men who have sex with men living with HIV.

In prior studies, the relationship between serostatus disclosure and reduced HIV transmission risk has been mixed. The demonstration of a clear connection may be restricted by three main methodological limitations. This study evaluates the relationship between (1) more refined measures of serostatus disclosure and (2) eight categories of HIV transmission risk (lowest to highest risk) among men who have sex with men (MSM) living with HIV, while (3) considering a number of control variables. Results demonstrate that disclosure is more likely in sexual encounters involving no intercourse or involving protected and unprotected anal intercourse with HIV-positive partners than unprotected insertive anal intercourse with HIV-negative/unknown status partners. Additionally, substance use prior to sexual encounters is less likely in lower risk categories than the highest risk category. Results of this study are important to the design of future studies, prevention, and intervention programs for MSM and to the methods used to evaluate their effectiveness.

A Systematic Review of Gay, Lesbian, and Bisexual Research Samples in Couple and Family Therapy Journals.

The purpose of this study is to review samples from research on gay, lesbian, and bisexual (GLB) issues and to evaluate the suitability of this body of research to support affirmative and evidence-based practice with GLB clients. The authors systematically reviewed the sampling methodology and sample composition of GLB-related research. All original, quantitative articles focusing on GLB issues published in couple and family therapy (CFT)-related journals since 1975 were coded (n = 153). Results suggest that within the GLB literature base there is some evidence of heterocentrism as well as neglect of issues of class, race, and gender. Suggestions to improve the diversity and representativeness of samples-and, thus, clinical implications-of GLB-related research in CFT literature are provided.

The efficacy of serostatus disclosure for HIV Transmission risk reduction.

Interventions to assist HIV+ persons in disclosing their serostatus to sexual partners can play an important role in curbing rates of HIV transmission among men who have sex with men (MSM). Based on the methods of Pinkerton and Galletly (AIDS Behav 11:698-705, 2007), we develop a mathematical probability model for evaluating effectiveness of serostatus disclosure in reducing the risk of HIV transmission and extend the model to examine the impact of serosorting. In baseline data from 164 HIV+ MSM participating in a randomized controlled trial of a disclosure intervention, disclosure is associated with a 45.0 % reduction in the risk of HIV transmission. Accounting for serosorting, a 61.2 % reduction in risk due to disclosure was observed in serodisconcordant couples. The reduction in risk for seroconcordant couples was 38.4 %. Evidence provided supports the value of serostatus disclosure as a risk reduction strategy in HIV+ MSM. Interventions to increase serostatus disclosure and that address serosorting behaviors are needed.

Women's HIV disclosure to family and friends.

Previous researchers have documented rates of HIV disclosure to family at discrete time periods, yet none have taken a dynamic approach to this phenomenon. The purpose of this study is to take the next step and provide a retrospective comparison of rates of women's HIV disclosure to family and friends over a 15-year time span. Of particular interest are the possible influences of social network and relationship characteristics on the time-to-disclosure of serostatus. Time-to-disclosure was analyzed from data provided by 125 HIV-positive women. Participants were primarily married or dating (42%), unemployed (79.2%), African American (68%) women with a high school diploma or less (54.4%). Length of time since diagnosis ranged from 1 month to over 19 years (M=7.1 years). Results pointed to statistically significant differences in time-to-disclosure between family, friends, and sexual partners. Additionally, females and persons with whom the participant had more frequent contact were more likely to be disclosed to, regardless of the type of relationship. The results of this study underscore possible challenges with existing studies which have employed point prevalence designs, and point to new methods which could be helpful in family research.

Predictors of parental monitoring among families with a runaway adolescent.

Extensive research shows that parental monitoring is a critical factor in child adjustment. Using parent and adolescent reports, this study sought to examine predictors of parental monitoring among an understudied, high-risk sample of runaway adolescents. Parent-reported depressive symptoms, couple (romantic) relationship satisfaction, and adolescent-reported bonding with parents were used as predictors of both child- and parent-reported monitoring. Findings indicated that, among parents, the couple relationship was the primary predictor of monitoring, whereas among adolescents, the parent-child relationship was the primary predictor. Maternal depressive symptoms were unrelated to monitoring. These findings suggest the utility of considering monitoring as an interpersonal phenomenon rather than primarily a parent- or child-driven phenomenon.

Tabletop scenarios for realism in bioterrorism and threat preparedness.

Five realistic tabletop scenarios were designed to facilitate threat preparedness training of Medical, Public Health, Nursing, Emergency Services, Mental Health, Allied Health, and Pharmacy personnel. Training scenarios were (1) student contaminates lettuce (Act) in a state university with Shigella sonnei (Agent), (2) dismissed athlete contaminates ice (Act) at the basketball tournament with Escherichia coli (Agent), (3) workers fail to report abandoned backpacks (Act) at a state fair that contain smallpox virus (Agent), (4) terrorists expose county residents (Act) to Pneumonic plague bacterium (Agent), and (5) infected birds expose field-trip participants (Act) to Avian influenza virus (Agent). Evaluation of the tabletops yielded positive ratings of educational outcomes in these domains: well-structured, organized, plausible, realistic, engaging, on-target, useful, and multidisciplinary. Attendees with previous blended-learning courses on bioterrorism and threat preparedness enhanced performance in the tabletop exercises. Evaluative data indicated a new level of competence and self-confidence about being part of a coordinated, local-level, interdisciplinary response.

An intervention to assist men who have sex with men disclose their serostatus to family members: results from a pilot study.

The purpose of this study was to evaluate the efficacy of an intervention to assist HIV positive men who have sex with men (MSM) in forming and executing strategies for the disclosure of their serostatus to their families of origin. Results indicate that the intervention was successful in assisting men with the primary outcome of disclosure. Participants reported no regret with disclosures occurring during the intervention and follow-up period. Effects on secondary outcomes including family functioning, depression, loneliness, and perceived social support were inconclusive. Implications, refinements of this intervention, and suggestions for future disclosure research are provided.

Comparing regret of disclosing HIV versus sexual orientation information by MSM.

Very little research has been conducted focusing on regret associated with disclosing either HIV-positive serostatus or sexual orientation information. The purpose of this study was to investigate the prevalence of regret related to the disclosure of serostatus and sexual orientation to family members among HIV-positive men who have sex with men (MSM) and to further explore the participant, family member, and relationship characteristics that influence the likelihood of experiencing regret. Almost half of participants indicated no regret with the disclosure of either HIV-positive serostatus or sexual orientation. Among those that did experience some regret, the prevalence of regret with at least one family member was similar for HIV-positive serostatus (39.4%) and for sexual orientation (37.3%). Suggestions for professionals working with HIV-positive MSM and implications for future research are presented.

An intervention to assist men who have sex with men disclose their serostatus to casual sex partners: results from a pilot study.

This article reports pilot data from a newly developed disclosure intervention and associated measures specifically tailored for disclosure to casual sexual partners. Treatment consisted of a four-session, theoretically driven intervention focusing on the costs and benefits of disclosure. Using a randomized control, crossover design 77 men were randomized into one of three conditions (wait-list control, facilitator only, and computer and facilitator). Results of the study suggest that facilitated administration of the pilot intervention was effective in reducing mean scores on the HIV disclosure behavior and attitude scales and that these reductions were both statistically and practically significant.

Bright-Field and Fluorescence Microscopic Study of Development of Erysiphe polygoni in Susceptible and Resistant Bigleaf Hydrangea.

Temporal development of Erysiphe polygoni and responses of bigleaf hydrangeas (Hydrangea macrophylla) to the fungal attack were investigated using bright-field and fluorescence microscopy. Conidia germinated 2 h after inoculation (HAI) and formed primary appressoria at the tip of the primary germ tubes within 4 HAI. Secondary germ tubes were initiated from primary appressoria or other parts of conidia 12 HAI. Hyphae developed through elongation of secondary germ tubes, and paired lateral appressoria were formed along hyphae within 2 days after inoculation (DAI). Conidiophores and conidia were formed 5 DAI. In the susceptible cultivar Nikko Blue and the resistant cultivar Veitchii, the fungus established a parasitic relationship, which was indicated by the formation of haustoria under primary appressoria and development of secondary germ tubes at 1 DAI. A hypersensitive response (HR) and accumulation of callose were detected in both resistant and susceptible cultivars at 3 DAI. Resistance to powdery mildew in Veitchii was evident by manifestation of early accumulation of callose, relatively high percentage of necrotic infected cells, and restricted colony development compared to the susceptible cultivar Nikko Blue. Restricting hyphal growth and sporulation by early response of callose accumulation and HR are important resistance mechanisms that could be used in screening hydrangeas for resistance to powdery mildew.
