A Qualitative Study of the Social Relationship Experiences Across the Life Course Among Black/African American Women Aging With HIV in the South.

Black/African American women continue to be disproportionately affected by HIV, facing multiple intersecting challenges that influence how they age and effectively manage their health. Supportive social relationships have been shown to help mitigate challenges and improve health in women with HIV, but little is known about Black/African American women's perceptions of social relationships. Guided by Life Course Theory, in-depth life history interviews were conducted with 18 Black/African American women aged 50+ years.

Parent-adolescent influences on everyday dietary practices: Perceptions of adolescent females with obesity and their mothers.

Parents demonstrate an important influence on adolescent obesity and dietary behavior; yet, family-based obesity interventions continue to exhibit limited success among adolescents. To further inform family-based approaches for adolescent obesity treatment, we examined the perceptions of adolescent females with obesity and their mothers of the influences experienced within the parent-adolescent relationship that affect everyday dietary practices. We conducted six focus group interviews (three adolescent female and three mother) among 15 adolescent (12-17 years old) females with obesity and 12 of their mothers.

A randomized controlled trial of the efficacy of a stigma reduction intervention for HIV-infected women in the Deep South.

The aim of this study was to compare outcomes (self-esteem, coping self-efficacy, and internalized stigma) across time in HIV-infected women living in the Deep South who received a stigma reduction intervention (n=51) with those of a control group (n=49) who received the usual care at baseline, and at 30 and 90 days. We recruited 99 women from clinics and an AIDS service organization; they were randomized by recruitment site. A video developed from the results of a qualitative metasynthesis study of women with HIV infection was loaded onto iPod Touch devices.

Differential expression of Homer1a in the hippocampus and cortex likely plays a role in radiation-induced brain injury.

Fractionated partial or whole-brain irradiation is the primary treatment for metastatic brain tumors. Despite reducing tumor burden and increasing lifespan, progressive, irreversible cognitive impairment occurs in >50% of the patients who survive >6 months after fractionated whole-brain irradiation. The exact mechanism(s) responsible for this radiation-induced brain injury are unknown; however, preclinical studies suggest that radiation modulates the extracellular receptor kinase signaling pathway, which is associated with cognitive impairment in many neurological diseases.

Concurrent substance abuse is associated with sexual risk behavior among adults seeking treatment for prescription opioid dependence.

Background: Increasingly, new HIV infections among people who use drugs are attributed to sexual risk behavior. However, HIV prevention research targeting persons with opioid dependence continues to focus on drug injection practices. Moreover, despite the rising prevalence of prescription opioid dependence in the United States, little is known about HIV risk in this population.

Angiotensin-(1-7) prevents radiation-induced inflammation in rat primary astrocytes through regulation of MAP kinase signaling.

About 500,000 new cancer patients will develop brain metastases in 2013. The primary treatment modality for these patients is partial or whole brain irradiation which leads to a progressive, irreversible cognitive impairment. Although the exact mechanisms behind this radiation-induced brain injury are unknown, neuroinflammation in glial populations is hypothesized to play a role.
