    ABSTRACT: In this focus group study, we explored the experiences of 16 rural women living with AIDS (WLA) who participated in the Asha-Life (AL) intervention to gain an understanding of the environmental, psychosocial and cultural impact of the AL on their lives. Four themes emerged among AL participants: (a) the importance of tangible support, (b) need for social support, (c) ongoing challenges to accessing antiretroviral therapy (ART), and (d) perspectives on future programs. Our research findings support the development of future programs targeting mother-child dyads which emphasize nutritional knowledge, while reducing barriers to receiving ART, and physical, emotional, and financial support.

    ABSTRACT: A randomized controlled trial was conducted with homeless gay and bisexual men to assess the impact of two culturally sensitive intervention programs on reduction of drug use and risky sexual behavior. In this study, gay and bisexual men between 18 and 46 years of age were randomly assigned to one of two culturally sensitive behavioral intervention programs: a Nurse Case Management Plus Contingency Management (NCM + CM; n = 204) or a Standard Education Plus Contingency Management (SE + CM; n = 210) program. Regardless of group assignment, significant and clinically relevant reductions were observed in stimulant use over time. Multivariable predictors of stimulant use at 4- and 8-month follow-up evaluations were recent injection drug use, tested positive for HIV, or for use of amphetamine. Data revealed a significant linear decline over time for those who had sex with multiple partners. Furthermore, being HIV positive was associated with reporting multiple partners, while higher homophobia scores and having children were inversely related to reports of having sex with multiple partners at follow-up. Culturally sensitive approaches are needed to successfully reduce drug use and risky sexual activities among gay and bisexual populations. © The Author(s) 2015.

    ABSTRACT: Although hepatitis A virus (HAV) and hepatitis B virus (HBV) infections are vaccine-preventable diseases, few homeless parolees coming out of prisons and jails have received the hepatitis A and B vaccination series. The study focused on completion of the HAV and HBV vaccine series among homeless men on parole. The efficacy of three levels of peer coaching (PC) and nurse-delivered interventions was compared at 12-month follow-up: (a) intensive peer coaching and nurse case management (PC-NCM); (b) intensive PC intervention condition, with minimal nurse involvement; and (c) usual care (UC) intervention condition, which included minimal PC and nurse involvement. Furthermore, we assessed predictors of vaccine completion among this targeted sample. A randomized control trial was conducted with 600 recently paroled men to assess the impact of the three intervention conditions (PC-NCM vs. PC vs. UC) on reducing drug use and recidivism; of these, 345 seronegative, vaccine-eligible subjects were included in this analysis of completion of the Twinrix HAV/HBV vaccine. Logistic regression was added to assess predictors of completion of the HAV/HBV vaccine series and chi-square analysis to compare completion rates across the three levels of intervention. Vaccine completion rate for the intervention conditions were 75.4% (PC-NCM), 71.8% (PC), and 71.9% (UC; p = .78). Predictors of vaccine noncompletion included being Asian and Pacific Islander, experiencing high levels of hostility, positive social support, reporting a history of injection drug use, being released early from California prisons, and being admitted for psychiatric illness. Predictors of vaccine series completion included reporting having six or more friends, recent cocaine use, and staying in drug treatment for at least 90 days. Findings allow greater understanding of factors affecting vaccination completion in order to design more effective programs among the high-risk population of men recently released from prison and on parole.

    ABSTRACT: This study was part of a randomized controlled trial designed to improve hepatitis knowledge and health promoting behaviors and subsequently decrease stimulant use and incarceration with 422 (G/B) homeless men between 18 and 46 years of age. Findings revealed that no significant program differences on incarceration in the 4 months following the intervention. However, younger participants (p = .010), and those with prior incarceration (p = .001) were at greater risk for incarceration at 4 months. An additional factor associated with incarceration at 4 months included living on the street for at least 1 week (p = .049).

    ABSTRACT: While there is an abundance of cancer survivorship research among various racial/ethnic groups, there is a paucity of research on survivors of African descent. To date, the meaning of survivorship has not been reported exclusively among African American breast cancer survivors (AABCS). The purpose was to describe and understand the meaning of survivorship among community-dwelling AABCS, mostly recruited from breast cancer support groups. Using a qualitative descriptive approach, an open-ended questionnaire explored the meaning of survivorship among 155 AABCS. An analysis of the content was performed. Among AABCS, survivorship meant having a strong spiritual base, thriving, being resilient, and being altruistic. The survivors self-identified with and embraced the term survivor. These results provide an important understanding of the perspectives and meaning of survivorship among AABCS and may assist in developing cancer survivorship care plans that are relevant, responsive, patient centered, and culturally appropriate. © The Author(s) 2014.

    ABSTRACT: This pilot study demonstrates the roles of popular culture, media and the arts in the health and self-esteem of homeless youth. Reflecting focus group findings from a representative sample of street and sheltered youth, this article provides a qualitative assessment of what they advocated as an effective intervention that would promote the receipt of health services within their vulnerable community. Unlike alienating disease models where adverse health behaviors and outcomes determine intervention success or failure, a culturally-sensitive approach which provided skills mentoring and engaged the youth as health advocates seemed likely to produce important recovery incentives and enhanced health outcomes.

    ABSTRACT: Abstract Our study examined the relationships of biological and psychosocial predictors as contributing factors to the psychological functioning among breast cancer survivors. A sample of (N = 155) African American breast cancer survivors were recruited from California. A general linear model was utilized to examine the relationships. Biological and psychosocial risk factors were significant predictors for anxiety and depression. These predictors can be viewed as contributing factors to the psychological well-being of this cohort. Anxiety and depression are often under-recognized and subsequently under-treated in survivors. Understanding the predictors of depression and anxiety is necessary for incorporating a multidisciplinary approach to address this problem.

    ABSTRACT: Introduction: A 2-day training program was developed to train Homoeopathy and Ayurveda practitioners to impart HIV/AIDS prevention messages to their clients. The purpose of the study was to evaluate the effectiveness of this training program based on train the trainer modality. Materials and Methods: Ten primary participants were enrolled in each one day and two day training program. Both the groups were instructed to impart further training to 10 participants each. The knowledge of and attitudes toward HIV/AIDS were measured in primary participants before and immediately after training and at the end of 3 months and in secondary participants before and immediately after training by a 21-item questionnaire. Results: In 1-day group, the pre-training and post-training assessments were completed by all the 10 participants, where as the 3 month assessment was completed by only seven participants. In this group, mean overall knowledge score was 15.9 which increased to 17 post training and reduced to 16.7, 3 months post training. In 2-day group, the pre-training and post training assessments were completed by 10 participants, where as the 3 month assessment was completed by nine participants. In this group, the pre-training score of 17.4 increased to 19.8 immediately after training and decreased to 18.4, 3 months after training. From the 1-day group and two day group, seven and nine participants respectively, conducted secondary trainings. In case of secondary trainees, the cognitive knowledge scores showed a statistically significant difference before and after trainings in both the groups. Conclusion: The training module on HIV/AIDS was useful in enhancing the knowledge of physicians of Homoeopathy and Ayurveda on cognitive and transmission related aspects of the disease and on its ethical, social and legal implications. With such training programs the homoeopathic and ayurvedic practitioners can play a vital role in prevention of HIV infection by undertaking appropriate patient education and counselling

    ABSTRACT: Abstract This cross-sectional study of 540 homeless ex-offenders exiting prisons and jails assessed sociodemographic, childhood and drug-related differences. Older ex-offenders from prison were more likely to have been married, come from a two-parent family and used crack while younger ex-offenders were more likely to have used methamphetamine. Older ex-offenders from jail were more likely to be African-American, have children, and report a history of crack and injection drug use, while those younger were more likely to have engaged in binge drinking and be in a gang. Our findings showcase the need to understand unique correlates of younger and older incarcerated populations.

    ABSTRACT: Gay and bisexual (G/B) homeless adults face multiple challenges in life which may place them at high risk for incarceration. Yet, little is known about this understudied population in terms of risk for incarceration. Baseline data collected from a longitudinal study between October 2009 and March 2012 in Hollywood, California, explored correlates of self-reported incarceration among G/B homeless stimulant-using adults (N = 353). Findings revealed older age, less education, having children, as well as a history of injection drug use and being born in the United States were positively associated with incarceration. Moreover, having poor social support and having received hepatitis information were also correlated with a history of incarceration. Our findings help us gain a greater awareness of homeless G/B adults who may be at greater risk for incarceration, which may be used by health care providers to design targeted interventions for this underserved population.

    ABSTRACT: High levels of hostility present a formidable challenge among homeless ex-offenders. This cross-sectional study assessed correlates of high levels of hostility using baseline data collected on recently-released male parolees (N=472; age 18-60) participating in a randomized trial focused on prevention of illicit drug use and recidivism. Predictors of high levels of hostility included greater depressive symptomatology, lower self-esteem, having a mother who was treated for alcohol/drugs, belonging to a gang, more tangible support, having used methamphetamine and having a history of cognitive difficulties. These findings highlight the need to understand predictors of hostility among recently released homeless men and how these predictors may relate to recidivism. Research implications are discussed as these findings will shape future nurse-led harm reduction and community-based interventions.

    ABSTRACT: Frailty is a public health issue that is experienced by homeless and other vulnerable populations; to date, a frailty framework has not been proposed to guide researchers who study hard-to-reach populations. The Frailty Framework among Vulnerable Populations has been developed from empirical research and consultation with frailty experts in an effort to characterize antecedents, that is, situational, health-related, behavioral, resource, biological, and environmental factors that contribute to physical, psychological, and social frailty domains and impact adverse outcomes. As vulnerable populations continue to age, a greater understanding of frailty will enable the development of nursing interventions.

    ABSTRACT: Homeless men exiting California State jails and prisons are a heterogeneous community with varied childhood, incarceration and drug use histories. This cross-sectional study assessed whether homeless men who were discharged from either jail or prison into a residential substance abuse treatment program, differed in terms of methamphetamine and heroin use. This study utilized baseline data collected on 540 recently paroled men randomized to one of three programs that assessed the impact of a peer coaching intervention on subsequent drug use and reincarceration. We found that younger ex-offenders exiting prisons and jails were more likely to have used methamphetamine alone, whereas African–American ex-offenders were less likely to have used methamphetamine alone when compared to other ethnic groups. Further, ex-offenders exiting jails and self-reporting use of heroin only at baseline were significantly more likely than their counterparts to have been removed from home before age 18 years. For men exiting jails, there was an association between lower self-esteem and having used methamphetamine but not heroin. However, having used both heroin and methamphetamine was associated with both violent crime and cognitive problems in both jail and prison samples. Our findings showcase the need to understand unique correlates of both heroin and methamphetamine as they relate to jail and prison populations.

    ABSTRACT: This cross-sectional study assessed predictors of Hepatitis C virus (HCV) positivity with baseline data collected on recently released male parolees (N = 157) participating in a randomized trial focused on reduction of drug use, recidivism, and risk for hepatitis and HIV infections. In this sample, the prevalence of HCV was 25%. The logistic regression analysis revealed that being an injection drug user was significantly related to HCV infection. However, contrary to most of the current literature, being Black had significantly lower odds of contracting HCV than their White counterparts. Moreover, having lived on the streets, not being part of a close family in childhood, and being older were also associated with HCV infection. These findings highlight the need for skilled assessments that target the vulnerabilities of homeless adults, especially those who have been incarcerated. Understanding drug use patterns, childhood networks, and family relationships, may assist in the design of interventions to reduce risky drug use and address behaviors derived from disadvantaged childhood.

    ABSTRACT: The current study focuses on the relationships among a trauma history, a substance use history, chronic homelessness, and the mediating role of recent emotional distress in predicting drug treatment participation among adult homeless people. We explored the predictors of participation in substance abuse treatment because enrolling and retaining clients in substance abuse treatment programs is always a challenge particularly among homeless people. Participants were 853 homeless adults from Los Angeles, California. Using structural equation models, findings indicated that trauma history, substance use history and chronicity of homelessness were associated, and were significant predictors of greater recent emotional distress. The most notable result was that recent emotional distress predicted less participation in current substance abuse treatment (both formal and self-help) whereas a substance use history alone predicted significantly more participation in treatment. Implications concerning treatment engagement and difficulties in obtaining appropriate dual-diagnosis services for homeless mentally distressed individuals are discussed.

    ABSTRACT: Homeless urbanites are a heterogeneous population with unique health and social service needs. The study examined situational, behavioral, health-related and resource indicators in terms of their direct impact on frailty, hypothesized as a latent variable. Using structural equation modeling (SEM), a model was tested with 150 homeless men and women, ages 40–73, from three homeless day center drop-in sites on Skid Row and one residential drug treatment (RDT) facility that works with homeless parolees and probationers. In bivariate analyses with the latent construct frailty, months homeless (p < 0.01), female gender (p < 0.05), education (p < 0.05), comorbid conditions (p < 0.001), nutrition (p < 0.001), resilience (p < 0.001), health care utilization (p < 0.01), and falls (p < 0.001) were significantly associated with frailty. In the final path model, significant predictors of frailty included educational attainment (p < 0.01), comorbid conditions (p < 0.001), nutrition (p < 0.001), resilience (p < 0.001), and falls (p < 0.01). These findings will serve as a foundation for future nurse-led, community-based initiatives that focus on key predictors of frailty among the homeless and the development of interventions.

    ABSTRACT: Homeless men on parole are a hard-to-reach population with significant community reintegration challenges. This cross-sectional study describes sociodemographic, cognitive, psychosocial, and drug-related correlates of alcohol and methamphetamine use in 157 homeless male parolees (age range 18-60) enrolled in a substance abuse treatment center in Los Angeles, California. Logistic regression results revealed that being African American and older were negatively related to methamphetamine use, whereas being older and more hostile were related to riskier alcohol abuse. Findings from this study provide a greater understanding of correlates of methamphetamine and alcohol--two of the most detrimental forms of substances abused among currently homeless parolees.

    ABSTRACT: Objectives: Researchers have proposed biological (inflammation) and psychological (depression) factors as potential mechanisms for poorer outcomes and readmissions in heart failure (HF) patients. However, studies investigating the link between inflammation and depressive symptoms in these patients are few. We examined the relationships between levels of the inflammatory markers C-reactive protein (CRP), interleukin (IL)-6, and soluble tumor necrosis factor receptor 2 (sTNR2) and depressive symptoms in HF outpatients. Method: 55 patients (74.5% men; 60% Whites; mean age 71.6 ± 11.3 years) with New York Heart Association Class II, III, or IV HF (49%, 47%, and 4%, respectively) and mean ejection fraction (EF) 29.9 ± 7.1% completed the Patient Health Questionnaire (PHQ)-9 as a measure of depressive symptoms. We also obtained height, weight, and CRP, IL-6, and sTNFR2 levels. We used multivariate regressions to assess the predictive value of PHQ-9 scores on each inflammatory marker. Results: 22 (40%) participants reported depressive symptoms (PHQ-9 score ≥ 5). After controlling for age, gender, body mass index, HF etiology, EF, and statin use, we found significant relationships between levels of both sTNFR2 (β = .35, p = .01) and IL-6 (β = .30, p = .04), but not CRP (β = -.96, p = .52), and depression scores. Conclusion: Our findings add to a growing body of evidence supporting the proposition that heightened inflammation explains the effect depression has on HF. Health care providers should screen for depression in HF patients, as they may be at higher risk of augmented inflammation and poor outcomes.

    ABSTRACT: Frailty, a relatively unexplored concept among vulnerable populations, may be a significant issue for homeless adults. This cross-sectional study assessed correlates of frailty among middle age and older homeless adults (N = 150, 40-73). A Pearson (r) bivariate correlation revealed a weak relationship between frailty and being female (r = .230, p < .01). Significant moderate negative correlations were found between frailty and resilience (r = -.395, p < .01), social support (r = -.377, p < .01), and nutrition (r = -.652, p < .01). Furthermore, Spearman's rho (rs) bivariate correlations revealed a moderate positive relationship between frailty and health care utilization (rs = .444, p < .01). A stepwise backward linear regression analysis was conducted and in the final model, age, gender, health care utilization, nutrition, and resilience were significantly related to frailty. Over the next two decades, there is an anticipated increase in the number of homeless adults which will necessitate a greater understanding of the needs of this hard-to-reach population.
