- Abstract
Abstract: Chimeric antigen receptor (CAR) T-cell therapies have demonstrated transformative efficacy in treating B-cell malignancies. However, high costs and manufacturing complexities hinder their widespread use. To overcome these hurdles, we have developed the VivoVec platform, a lentiviral vector capable of generating CAR T cells in vivo. Here, we describe the incorporation of T-cell activation and costimulatory signals onto the surface of VivoVec particles (VVPs) in the form of a multidomain fusion protein and show enhanced in vivo transduction and improved CAR T-cell antitumor functionality. Furthermore, in the absence of lymphodepleting chemotherapy, administration of VVPs into nonhuman primates resulted in the robust generation of anti-CD20 CAR T cells and the complete depletion of B cells for >10 weeks. These data validate the VivoVec platform in a translationally relevant model and support its transition into human clinical testing, offering a paradigm shift in the field of CAR T-cell therapies., (© 2024 American Society of Hematology.

- Abstract
Background: Although clinical substance use disorder (SUD) care is multidisciplinary there are few opportunities to collaborate for quality improvement or systems change. In Oregon, the Project ECHO (Extension for Community Healthcare Outcomes) model was adapted to create a novel multidisciplinary SUD Leadership ECHO. The objective of this study was to understand the unique effects of the adapted ECHO model, determine if the SUD Leadership ECHO could promote systems change, and identify elements that enabled participant-leaders to make changes., Methods: Four focus groups were conducted between August and September of 2022 with a purposive sample of participants from the second cohort of the Oregon ECHO Network's SUD Leadership ECHO that ran January to June 2022. Focus group domains addressed the benefits of the adapted ECHO model, whether and why participants were able to make systems change following participation in the ECHO, and recommendations for improvement. Thematic analysis developed emergent themes., Results: 16 of the 53 ECHO participants participated in the focus groups. We found that the SUD Leadership ECHO built a multi-disciplinary community of practice among leaders and reduced isolation and burnout. Three participants reported making organizational changes following participation in the ECHO. Those who successfully made changes heard best practices and how other organizations approached problems. Barriers to initiating practice and policy changes included lack of formal leadership authority, time constraints, and higher-level systemic issues. Participants desired for future iterations of the ECHO more focused presentations on a singular topic, and asked for a greater focus on solutions, advocacy, and next steps., Conclusions: The adapted ECHO model was well received by focus group participants, with mixed reports on whether participation equipped them to initiate organizational or policy changes. Our findings suggest that the SUD Leadership ECHO model, with fine-tuning, is a promising avenue to support SUD leaders in promoting systems change and reducing isolation among SUD leaders., (© 2024.

- Abstract
Background: Parkinson's disease is the second most common neurodegenerative disorder and presents with a heterogeneous group of symptoms. Managing these symptoms requires coordinated care from a neurology specialist and a primary care provider. Access to neurology care is limited for those patients with Parkinson's disease who reside in rural areas given financial and mobility constraints along with the rarity of specialty providers., Methods: To close this gap, we developed and implemented a telehealth-based Project ECHO® (Extension for Community Healthcare Outcomes) program, "Parkinson ECHO," to provide education and support for rural clinicians and allied health members. The sessions focused on a topic within Parkinson's disease diagnosis or management followed by case discussions. We assessed the feasibility of this tele-mentoring educational offering, the favorability of this approach, and the effect it had on clinician confidence in diagnosing and treating Parkinson's disease using Likert-based surveys., Results: Thirty-three unique participants from 13 Oregon counties and one county in the state of Washington, of whom 70 % served rural and/or medically underserved communities, participated in Parkinson ECHO. There was a 52 % dropout rate based on survey response, though session attendance was higher. Participants were overall satisfied with the format and content of Parkinson ECHO. There were improvements in knowledge and confidence in diagnosing and treating Parkinson's disease which persisted 6 months following the conclusion of the program. Unexpectedly, two participants reported convening a multidisciplinary group to discuss improvements to PD care., Conclusion: The COVID-19 pandemic was an unexpected obstacle, but the teleconference nature permitted us to complete the program to positive effect. We found Parkinson ECHO did significantly increase participant confidence levels in diagnosing and managing Parkinson's disease., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

- Abstract
Background: Uninformed opioid prescribing by dentists has contributed to the current opioid crisis. This report describes the development and implementation of an innovative, interactive, multidisciplinary, and participant-centric telementoring program "Pain Management and Substance Use Disorders Dental ECHO (Extension for Community Health Care Outcomes)". We disseminated information to dentists about appropriate opioid prescribing practices and engaged them with a focus on pain management and substance use disorders. The objective of this study was to assess the effectiveness of this program for self-reported: (1) change in knowledge and confidence related to clinical skills for dental pain management of patients with substance use disorders; (2) change in clinical behavior of dentists for safe opioids prescribing; and (3) change in clinic policies regarding safe opioids prescribing., Methods: An interdisciplinary panel of experts in medicine, pharmacy, social work, and dentistry designed and led the "Pain Management and Substance Use Disorders Dental ECHO" for invited dental care providers and dental students. Six cohorts each consisting of six, 1-h-long sessions were conducted via the Zoom videoconference platform in years 2020 and 2021. Each session included a didactic expert presentation, a participant-presented patient case and discussion. Each participant completed pre- and post-program surveys to assess the program's influence on participant knowledge, clinical confidence and behavior change., Results: The participants (N = 151) were dentists (n = 109), dental faculty (n = 15), dental residents (n = 6), dental hygienists/assistants (n = 13) and nurses and clinic administrators (n = 8). Self-reported perceived medication knowledge, confidence in identification, treatment and willingness to engage with substance use disorders patients, and reported compliance with Prescription Drug Monitoring Program (PDMP) checks increased significantly from before to after the sessions (p < 0.001). Overall, participants expressed high levels of satisfaction with the content and reported that the sessions provided high benefit., Conclusion: The Project ECHO model is effective in rapidly disseminating evidence-based information. Dentists viewed this model as having a high degree of benefit for the optimal management of dental pain and the recognition and treatment of substance use disorders., (© 2022. The Author(s).)

- Abstract
The APOBEC3 (A3) genes encode cytidine deaminase proteins with potent antiviral and anti-retroelement activity. This locus is characterized by duplication, recombination, and deletion events that gave rise to the seven A3s found in primates. These include three single deaminase domain A3s (A3A, A3C, and A3H) and four double deaminase domain A3s (A3B, A3D, A3F, and A3G). The most potent of the A3 proteins against HIV-1 is A3G. However, it is not clear if double deaminase domain A3s have a generalized functional advantage to restrict HIV-1. In order to test whether superior restriction factors could be created by genetically linking single A3 domains into synthetic double domains, we linked A3C and A3H single domains in novel combinations. We found that A3C/A3H double domains acquired enhanced antiviral activity that is at least as potent, if not better than, A3G. Although these synthetic double domain A3s package into budding virions more efficiently than their respective single domains, this does not fully explain their gain of antiviral potency. The antiviral activity is conferred both by cytidine-deaminase dependent and independent mechanisms, with the latter correlating to an increase in RNA binding affinity. T cell lines expressing this A3C-A3H super restriction factor are able to control replicating HIV-1ΔVif infection to similar levels as A3G. Together, these data show that novel combinations of A3 domains are capable of gaining potent antiviral activity to levels similar to the most potent genome-encoded A3s, via a primarily non-catalytic mechanism., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Two key advancements in improving the quality of primary care have been practice-based research networks (PBRNs) and Project Extension for Community Health care Outcomes (ECHO). PBRNs advance quality through research and transformation projects, often using practice facilitation. Project ECHO uses case-based telementoring to support community clinicians to deliver best-practice care. Although some PBRNs sponsor ECHO programs, the Oregon Rural Practice-based Research Network (ORPRN) has created a statewide network for ECHO programs (Oregon ECHO Network [OEN]). We facilitated a unique funding stream for the OEN by partnering with payers and health systems. The purpose of this article is to share our experience of how OEN programs and ORPRN research and transformation projects enhance practice recruitment and retention and improve financial stability. We describe the synergy between ORPRN projects and ECHO programs using 3 examples: tobacco cessation, chronic pain and opioid prescribing, and diabetes management. We highlight challenges and opportunities in these examples, beginning with their development, their implementation, and their ultimate alignment, despite varied funding streams and timelines. We believe that incorporating the OEN within ORPRN has been a success for both PBRN research and Project ECHO programs, allowing us to better support primary care practices across the state., Competing Interests: Conflict of Interest: None., (© Copyright 2020 by the American Board of Family Medicine.)

- Abstract
Humans encode proteins, called restriction factors, that inhibit replication of viruses such as HIV-1. The members of one family of antiviral proteins, apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3 (APOBEC3; shortened here to A3), act by deaminating cytidines to uridines during the reverse transcription reaction of HIV-1. The A3 locus encodes seven genes, named A3A to A3H These genes have either one or two cytidine deaminase domains, and several of these A3s potently restrict HIV-1. A3C, which has only a single cytidine deaminase domain, however, inhibits HIV-1 only very weakly. We tested novel double domain protein combinations by genetically linking two A3C genes to make a synthetic tandem domain protein. This protein created a "super restriction factor" that had more potent antiviral activity than the native A3C protein, which correlated with increased packaging into virions. Furthermore, disabling one of the active sites of the synthetic tandem domain protein resulted in an even greater increase in the antiviral activity-recapitulating a similar evolution seen in A3F and A3G (double domain A3s that use only a single catalytically active deaminase domain). These A3C tandem domain proteins do not have an increase in mutational activity but instead inhibit formation of reverse transcription products, which correlates with their ability to form large higher-order complexes in cells. Finally, the A3C-A3C super restriction factor largely escaped antagonism by the HIV-1 viral protein Vif. IMPORTANCE As a part of the innate immune system, humans encode proteins that inhibit viruses such as HIV-1. These broadly acting antiviral proteins do not protect humans from viral infections because viruses encode proteins that antagonize the host antiviral proteins to evade the innate immune system. One such example of a host antiviral protein is APOBEC3C (A3C), which weakly inhibits HIV-1. Here, we show that we can improve the antiviral activity of A3C by duplicating the DNA sequence to create a synthetic tandem domain and, furthermore, that the proteins thus generated are relatively resistant to the viral antagonist Vif. Together, these data give insights about how nature has evolved a defense against viral pathogens such as HIV., (Copyright © 2020 McDonnell et al.)

- Abstract
As national HIV prevention goals aim to increase the proportion of persons living with HIV, determining existing disparities in retention in care will allow for targeted intervention. The purpose of this systematic review was to identify existing disparities in retention in care. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) 2015 guided this systematic review. Electronic databases, including PubMed/MEDLINE, CINAHL, Sociological Collection, PsychInfo, and Cab Direct/Global Health, were systematically searched and twenty studies were included. This review identified disparities in retention in care that have been documented by race, gender, age, HIV exposure, incarceration history, place of birth, and U.S. geographic location. Research is necessary to further identify existing disparities in retention in care and to better understand determinants of health disparities. Additionally, interventions must be tailored to meet the needs of health disparate populations and should be assessed to determine their effectiveness in reducing health disparities.

- Abstract
Low health literacy and poor retention in care may contribute to HIV health disparities among African Americans, but causal pathways have not been examined. We utilized an adapted health literacy model to examine the role of health literacy on racial disparities in retention in care. Retention in care for 699 participants was assessed 24-months post survey and operationalized as 100% visit adherence versus less than 100% visit adherence. Most participants were African American (60%) and virally suppressed (93%). Results from a path analysis revealed that non-African American race was related to greater health literacy (p = .023) and to 100% visit adherence (p = .024). Greater health literacy was associated with 100% visit adherence (p = .008), which was in turn related to viral suppression (p < .001). Findings indicate that health literacy partially mediates the relationship between race and retention in care and are among the first to suggest these causal pathways.

- Abstract
This study examined factors impacting the psychological well-being of women living with human immunodeficiency virus/AIDS and the impact of depression on clinical outcomes. Nearly two-thirds of participants in this cross-sectional study reported significant depressive symptoms. Compared with women living with human immunodeficiency virus/AIDS without depressive symptoms, those with depression reported significantly poorer health outcomes. Health care providers should regularly screen these women for and adequately treat depression, and must collaborate with mental health providers and pastoral care counselors to address the mental health needs of women living with human immunodeficiency virus/AIDS to optimize their human immunodeficiency virus-related outcomes., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: Although fracture rates are higher in HIV+ than HIV- women, whether HIV infection increases risk of falls is unclear. We determined the longitudinal occurrence and risk factors for falls in the Women's Interagency HIV Study (WIHS), and explored associations with cognitive complaints., Methods: Recent (prior 6 months) self-reported falls were collected in 1,816 (1,250 HIV+; 566 HIV-) women over 24 months. Generalized estimating equation models using stepwise selection determined odds of any fall (versus none)., Results: HIV+ women were older than HIV- women (median 49 versus 47 years; P=0.0004), more likely to report neuropathy (20% versus 16%; P=0.023), and had greater central nervous system (CNS) medication use. At least one fall was reported in 41% HIV+ versus 42% HIV- women, including ≥2 falls in 25% HIV+ and 24% HIV- (overall P=0.30). Cognitive complaints were associated with falls among HIV+ (odds ratio [OR] 2.38; 95% CI 1.83, 3.09) and HIV- women (OR 3.43; 95% CI 2.37, 4.97); in adjusted models, cognitive complaints remained significant only in HIV- women (adjusted [aOR] 2.26; 95% CI 1.46, 3.48). Factors associated with any fall in adjusted analyses included: depressive symptoms and neuropathy (both HIV+ and HIV-); age, marijuana use, multiple CNS medications, and HCV infection (HIV+ only); and cognitive complaints, quality of life, hypertension and obesity (HIV- only)., Conclusions: Middle-aged HIV+ and HIV- women had similar fall rates. Among HIV+ women, factors affecting cognition such as age, depressive symptoms, marijuana use and multiple CNS medications were important predictors of falls, however, cognitive complaints were not.

- Abstract
Optimal adherence to antiretroviral therapy (ART) is associated with favorable HIV outcomes, including higher CD4 cell counts, HIV virus suppression and a lower risk of HIV transmission. However, only 25% of people living with HIV/AIDS (PLWH) in the USA are virally suppressed. Sub-optimal adherence (<90-95%) contributes to antiretroviral resistance and worse medical outcomes, including more rapid progression to AIDS and death. Psychosocial factors and religion/spirituality (R/S) have a significant impact on ART adherence, but the findings are mixed. The purpose of this study was to examine religious and psychosocial correlates and predictors of ≥90% ART adherence in PLWH. A cross-sectional study was conducted with a sample of 292 outpatient PLWH in the Southeastern USA. Participants completed computerized surveys. The mean ART adherence percentage was 80.9% and only about half reported ≥90% adherence. There were statistically significant differences in ART adherence rates based on age, depressive symptom status and frequency of religious attendance and prayer. Praying at least once a day was significantly associated with ≥90% ART adherence (OR = 2.26, 95% CI [1.06-4.79], p < 0.05). Social support satisfaction was also significantly associated with ART adherence (OR = 1.52, 95% CI [1.11-2.08], p < 0.05) and energy/fatigue/vitality (OR = 1.03, 95% CI [1.00-1.05], p < 0.05).

- Abstract
Background: Diabetes mellitus (DM) patients with comorbid hypertension (HTN) are at a higher risk of developing microvascular and macrovascular DM complications. Through guideline-driven recommendations, angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are highly recommended for these patients. Unfortunately, medication adherence to these products, though crucial to achieving therapeutic benefit, is frequently suboptimal. Motivational interviewing (MI) is a patient-centered collaborative communication style that is used to strengthen internal motivation for change that may prove effective in enhancing adherence., Objective: To examine the effect of an MI telephone intervention conducted by pharmacy students in improving adherence to ACEIs/ARBs among Medicare Advantage Plan (MAP) patients with both DM and HTN., Methods: A prospective study was conducted among patients enrolled in a Texas MAP. Medical claims data were used to identify patients with DM and HTN, and pharmacy claims were observed to recognize those who filled either an ACEI or an ARB during June 2014. Patients with a 6-month proportion of days covered (PDC) < 0.80 in the previous 6 months were determined nonadherent, and 75% of those were randomly selected to serve as potential subjects for the intervention, while 25% were randomly selected to serve as potential subjects for the control group. The intervention was a telephone call by a pharmacy student on rotation at the health plan, and 5 monthly follow-up calls. Before implementing calls, participating students attended a 3-day MI training course, where their proficiency for MI skills was evaluated. Refill data during the 6-month postintervention were evaluated to examine the intervention effect measured on 3 outcomes: PDC; PDC ≥ 0.80 versus < 0.80; and discontinuation versus continuation. Multivariate linear and logistic regression models were constructed to adjust for any imbalances in baseline characteristics, including age, gender, number of other medications, regimen complexity, health low-income subsidy status, prescriber specialty, comorbidities, 6-month previous hospitalization, baseline 6-month PDC, and Centers for Medicare & Medicaid Services risk score., Results: A total of 11 students participated in the intervention implementation. Patients receiving calls were randomly selected from those potential subjects for the intervention arm until a target of 250 was reached; 500 controls were randomly selected from the potential subjects for the control arm. The final cohort included in multivariate models consisted of 743 patients. Patients completing the initial call and at least 2 follow-ups were less likely to discontinue (OR = 0.29; 95% CI = 0.15-0.54; P < 0.001) and more likely to be adherent in the linear regression model (β = 0.0604, P < 0.001) and the logistic regression model (OR = 1.53; 95% CI = 1.02-2.28; P = 0.009). Other factors significantly associated with better adherence included higher baseline PDC and number of medications. Depression status was significantly associated with lower adherence., Conclusions: Patients receiving 2 or more calls had significantly better adherence and less discontinuation during the 6 months following initial calls compared with those who did not receive calls. This finding indicates that an MI-based telephone intervention by pharmacy students may be a promising intervention to improve adherence. Future research should examine the sustainability of the intervention effect for longer time periods and its influence on associated clinical outcomes., Disclosures: This project was supported by the Pharmaceutical Research and Manufacturers of America Foundation (PhRMA).

- Abstract
Due to life-enhancing effects of antiretroviral therapy, HIV-positive persons have the potential for long life comparable to their uninfected peers. Older women (age 50+) living with HIV (OWLH) are often an under-recognized aging group. We conducted a systematic review to examine psychosocial factors that impact how OWLH live, cope, and age with HIV. Initial key word search yielded 1527 records, and 21 studies met our inclusion criteria of original quantitative or qualitative research published between 2013 and 2016 with results specific to OWLH. These focused on health care and self-management, sexual health and risk, stigma, loneliness, mental health (depression, substance use), and protective factors (coping, social support, well-being). Due to the scarcity of studies on each topic and inconclusive findings, no clear patterns of results emerged. As the number of OWLH continues to grow, more research, including longitudinal studies, is needed to fully characterize the psychosocial factors that impact aging with HIV.

- Abstract
The purpose of this study was to identify key psychosocial characteristics of HIV-infected women who exhibit different levels of both ART adherence and risk behaviors. We analyzed baseline data from 193 predominately African American HIV-infected women participating in a behavioral clinical trial. Women were categorized into high/low groups based on levels of adherence and risky behaviors. There was a significant interaction effect for internal motivation for adherence. Women at high risk for poor health and transmitting HIV (low adherence/high risk group) had the lowest levels of internal motivation and also reported more difficult life circumstances. Gender roles, caretaking and reliance on men for economic and other support may promote external versus internal motivation as well as riskier behaviors in this group. The highest levels of internal motivation were found in those with High Adherence/High Risk behaviors. This group was highly knowledgeable about HIV and had the lowest VL. Compared to others, this group seems to tolerate risky behaviors given their high level of adherence. Adherence and risk reduction behaviors are key to individual and public health. Motivation and risk compensation should be addressed when providing interventions to women living with HIV.

- Abstract
Peroxisomes are single-membrane bound organelles that are essential for normal development in plants and animals. In mammals and yeast, the peroxin (PEX) proteins PEX3 and PEX19 facilitate the early steps of peroxisome membrane protein (PMP) insertion and pre-peroxisome budding from the endoplasmic reticulum. The PEX3 membrane protein acts as a docking site for PEX19, a cytosolic chaperone for PMPs that delivers PMPs to the endoplasmic reticulum or peroxisomal membrane. PEX19 is farnesylated in yeast and mammals, and we used immunoblotting with prenylation mutants to show that PEX19 also is fully farnesylated in wild-type Arabidopsis thaliana plants. We examined insertional alleles disrupting either of the two Arabidopsis PEX19 isoforms, PEX19A or PEX19B, and detected similar levels of PEX19 protein in the pex19a-1 mutant and wild type; however, PEX19 protein was nearly undetectable in the pex19b-1 mutant. Despite the reduction in PEX19 levels in pex19b-1, both pex19a-1 and pex19b-1 single mutants lacked notable peroxisomal β-oxidation defects and displayed normal levels and localization of peroxisomal matrix and membrane proteins. The pex19a-1 pex19b-1 double mutant was embryo lethal, indicating a redundantly encoded critical role for PEX19 during embryogenesis. Expressing YFP-tagged versions of either PEX19 isoform rescued this lethality, confirming that PEX19A and PEX19B act redundantly in Arabidopsis. We observed that pex19b-1 enhanced peroxisome-related defects of a subset of peroxin-defective mutants, supporting a role for PEX19 in peroxisome function. Together, our data indicate that Arabidopsis PEX19 promotes peroxisome function and is essential for viability.

- Abstract
Background: To determine the frequency and risk factors for falls among middle-aged HIV+ and HIV- women in the Women's Interagency HIV Study (WIHS)., Methods: We quantified self-report of any and multiple (≥2) falls in the prior 6 months among 1,412 HIV+ and 650 HIV- women with mean age 48 years. Logistic regression was used to evaluate associations of demographics, behavioural factors, comorbid conditions and medications with odds of any fall (versus none) and multiple falls (versus ≤1 fall)., Results: At least one fall was reported in 263 HIV+ (19%) versus 119 HIV- (18%) women, and ≥2 falls reported in 133 HIV+ (9%) versus 65 HIV- (10%) women. HIV infection was not associated with falls in multivariate analyses. Factors independently associated with any fall included age (adjusted odds ratio [aOR] 1.71, 95% CI 1.17, 2.49 age 50-59 versus <39 years; aOR 2.26, 95% CI 1.38, 3.71 age ≥60 versus <39), current marijuana use (aOR 2.19, 95% CI 1.53, 3.13) depressive symptoms (aOR 1.57, 95% CI 1.21, 2.05 for Center for Epidemiology Studies Depression score ≥16), subjective cognitive complaints (aOR 2.19, 95% CI 1.56, 3.08), neuropathy (aOR 1.59, 95% CI 1.19, 2.13), obesity (aOR 1.39, 95% CI 1.08, 1.80), number of central nervous system active agents (aOR 2.98, 95% CI 1.90, 4.68 for ≥3 agents versus 0) and WIHS site. Factors associated with ≥2 falls included age, marijuana use, number of central nervous system active agents, subjective cognitive complaints, depressive symptoms, neuropathy and study site., Conclusions: Falls were associated with factors affecting cognition, but not HIV status in this large cohort of women. Longitudinal studies are needed to determine the incidence and consequences of falls by HIV status as women age.

21. Religious and Psychosocial Covariates of Health-Related Quality of Life in People Living with HIV/AIDS.

- Abstract
HIV/AIDS is a chronic, highly stigmatized illness that requires significant lifestyle adjustments, including consistent adherence to Antiretroviral Therapy (ART) in order for People Living With HIV/AIDS (PLWH) to survive and maintain good immune health. PLWH often report poor or moderate Health-Related Quality of Life (HRQoL) that is worse than the general population. This may be related to the psychological and physiological demands of HIV disease and the sociodemographic stressors associated with it. The role of religious coping, religiosity, and social support in the mental and physical dimensions of HRQoL is less known, although recent studies highlight that PLWH rely on spirituality/religion to cope with HIV-associated stressors. This study examined the effects of religious coping, religiosity, depressive symptoms, medication adherence, and social support satisfaction in various dimensions of Health- Related Quality of Life (HRQoL) in a sample of 292 PLWH. Majority of participants were African-American (90.1%) and 56.2% were male. Mean age was 45 years and, on average, participants lived with HIV for nearly 11 years. Descriptive statistics, correlations, Analysis of Variance (ANOVA), and hierarchical multiple linear regression were used to analyze the data. Income, sex (β= .14), age (β= -.14), depressive symptoms (β= -.27), and social support satisfaction (β= .17) significantly predicted physical HRQoL. Results indicate that income (β= .13), sex (β= .14), medication adherence (β= .13), negative religious coping (β= -.18), religious attendance (β= .13), religiousness (β= .16), and social support satisfaction (β= .27) significantly predicted mental HRQoL. Depressive symptoms (β= -.38), positive religious coping (β= .24), and social support satisfaction (β= .16) significantly predicted general HRQoL. Participants, who were female, prayed less than daily, attended religious services less than weekly or who were non/less religious had significantly poorer HRQoL. The findings confirm the importance of religion, mental health, medication adherence and social support in the HRQoL of PLWH, which should all be routinely assessed by clinicians.

- Abstract
Stigma has become a gendered phenomenon that affects increasing numbers of HIV-infected women worldwide. This study examined the role of age as a possible moderator of the relationship between stigma and antiretroviral therapy adherence, CD4% and viral load among 120 HIV-infected women. A secondary analysis was conducted using data from the Keeping Healthy and Active with Risk Reduction and Medication Adherence (KHARMA) Project, an National Institutes of Health (NIH) funded randomized controlled trial to improve Antiretroviral treatment (ART) adherence and reduce risky behaviors in HIV-infected women at five clinical sites in a South-eastern city from 2005 to 2008. Stigma was measured using the Perceived Personal Stigma of Human Immunodeficiency Virus and Acquired Immune Deficiency Syndrome (HIV/AIDS) scale. Among participants <50 years old (n=90), age was significantly associated with viral load (rho=-.24, p=.02) and stigma was negatively associated with CD4% (r =-.26, p=.02). For the 30 participants >50 years old, age was not significantly associated with viral load, stigma or CD4%, and there was no significant association between stigma and CD4% (r=.07, p=.70). These findings indicate the need for further study regarding this potential moderating effect and possible interventions to address the susceptibility of younger women to the harmful effects of stigma.

- Abstract
We developed and pilot-tested the efficacy, acceptability, and feasibility of a music program, The LIVE Network (LN), compared to standard care on outcomes of ART adherence, clinical indicators, and self-efficacy. The study was powered to detect differences at p < 0.1. We enrolled and followed 77 participants for 12 weeks (T3). Mean monthly pill counts (PC) declined over time in both groups. Although not significant, the LN had higher PC and a larger proportion had plasma antiretroviral trough levels within therapeutic range. The LN group did have significantly (p < 0.1) increased levels of adherence self-efficacy and decrease in viral loads.

Hodges S and Holstad MM
- Abstract
This study investigates the efficacy of a health promotion educational program on improving cardiovascular risk factors of weight, Body Mass Index, and waist to hip ratio in 76 predominately African American HIV-infected women. The health promotion educational program was the control group (that focused on improving self-efficacy for nutrition, exercise, stress reduction and women's health behaviors) of a NIH-funded study. The majority of participants was overweight, obese, or at high risk based on waist hip ratio at the beginning of the study. There were no statistically significant improvements in body mass index or waist hip ratio from pre intervention to up to 9 months post intervention. There were significant changes in waist hip ratio and body mass index in both directions (improvement and worsened) for a small group of participants. The health promotion program did not affect significant changes in cardiovascular risk and should be revised, lengthened, and refocused on nutrition, diet, exercise, and long term goal commitments to reduce the high risk for cardiovascular disease in this group.

- Abstract
Objective: This study examined correlates of depressive symptoms, particularly the role of religious coping (RCOPE), among people living with HIV/AIDS (PLWHA). The study also examined social support as a possible mediator of the proposed association between religious coping and depressive symptoms and the impact of depressive symptomatology on health outcomes such as HIV medication adherence, immune function, and health-related quality of life (HRQOL) among PLWHA., Method: A convenience sample of 292 PLWHA were recruited from an out-patient infectious disease clinic and AIDS-service organizations in the Southeastern United States., Results: 56.7% reported depressive symptoms. PLWHA with depressive symptomatology reported significantly poorer health outcomes, including poorer HIV medication adherence, lower CD4 cell count, and poorer HRQOL. The odds of being depressed was significantly associated with birth sex (female: OR = 0.43, 95% CI = .23-.80), sexual orientation (gay/bisexual: OR = 1.95, 95% CI = 1.04-3.65), marital status (single: OR = .52, 95% CI = .27-.99), social support satisfaction (OR = 0.65, 95% CI = .49-.86), and negative RCOPE (OR = 1.22, 95% CI = 1.14-1.31). Social support partially mediated the relationship between religious coping and depressive symptoms., Conclusions: High rates of depressive symptoms are present in PLWHA, which negatively impact health outcomes. Religious coping, perceived stress, and social support satisfaction serve an important role in depressive symptomatology among PLWHA. These findings underscore the need for healthcare providers to regularly screen PLWHA for and adequately treat depression and collaborate with mental health providers, social workers, and pastoral care counselors to address PLWHA's mental, social, and spiritual needs and optimize their HIV-related outcomes.

- Abstract
This cross-sectional, correlational study, guided by the information-motivation-behavioral skills model and self-efficacy theory, investigated factors that may help to assess the HIV prevention needs of older adults. The nonrandom sample (N = 106) included single men and women, 50-74 years of age, who were either sexually active or had plans to be sexually active. Participants were recruited from community sites. Data were collected with questionnaires. Data analysis revealed that the participants had moderate levels of HIV knowledge, were highly motivated, and highly confident but continued to practice risky behaviors such as not using condoms with every sexual encounter (67.9%) and having multiple sex partners (34.6%). Higher perceived effectiveness to perform safer sexual behaviors, being female, and condom use were the only independent predictors of fewer risky sexual behaviors. Findings from this study may provide a foundation for future age-appropriate interventions to decrease HIV in older adults., (Copyright © 2012 Association of Nurses in AIDS Care.

- Abstract
The purpose of this qualitative study was to explore the meaning and use of spirituality among African American (AA), predominantly Christian women with HIV. A nonrandom sample of 20 AA women from a large infectious disease clinic in Metro-Atlanta participated in the study. The study used focus groups and individual interviews to interview women about their lived spiritual experience. Content analysis and NUDIST software were used to analyze transcripts. The findings revealed the spiritual views and practices of AA women with HIV. The following themes (and subthemes) emerged: Spirituality is a process/journey or connection (connection to God, higher power, or spirit and HIV brought me closer to God), spiritual expression (religion/church attendance, prayer, helping others, having faith), and spiritual benefits (health/healing, spiritual support, inner peace/strength/ability to keep going, and here for a reason or purpose/a second chance). Findings highlight the importance of spirituality in health and well-being among AA women with HIV/AIDS.

- Abstract
Nigerian women comprise the fastest growing group of persons with AIDS in Africa. Antiretroviral therapy has transformed the course of HIV/AIDS to a treatable, chronic illness worldwide. The purpose of this pilot study was to assess the efficacy of a group intervention using motivational interviewing (MI) to promote adherence to antiretroviral therapy (ART) and use of risk reduction behaviors (RRB) among HIV-infected women in Nigeria. Recruited participants (n=60) were randomly assigned to the motivational group or the health promotion program (HPP) control group. The 6 month follow-up results indicate that, compared to the control group, MI participants reported significantly higher levels of adherence to ART, higher knowledge of HIV, higher use of condoms/protection during sexual encounters and decision-making not to have sex when no protection was available. The MI participants also had fewer mean number of sexual partners. MI in group format shows promise in promoting adherence to ART and use of RRB in HIV-infected Nigerian women.

- Abstract
We present the results of 3 focus groups conducted to assess the utility, appeal, and feasibility of the LIVE Network (LN), a 70-minute audio music program developed to educate and motivate HIV-infected persons to adhere to antiretroviral therapy (ART) and self-manage medication-related side effects. Participants included 15 African American, 2 caucasian, and 1 race unknown HIV-infected persons who had been taking ART for at least 6 months. In general, the LN was well liked, relevant, educational, and motivational. It empowered and motivated participants to be responsible for their adherence self-care. One of the more surprising findings was how freely focus group participants shared the program with family and friends as a means of education and also as a means of disclosure. Moreover, the positive reception of the LN by individuals outside of the focus groups, especially children and adolescents, speaks well for the potential broad appeal of this type of program.

- Abstract
Objective: This study sought to determine whether aggressive glycemic control (90-120 mg/dL) would result in more optimal clinical outcomes and less morbidity than moderate glycemic control (120-180 mg/dL) in diabetic patients undergoing coronary artery bypass graft (CABG) surgery., Summary of Background Data: Maintaining serum glucose levels between 120 and 180 mg/dL with continuous insulin infusions decreases morbidity in diabetic patients undergoing CABG surgery. Studies in surgical patients requiring prolonged ventilation suggest that aggressive glycemic control (<120 mg/dL) may improve survival; however, its effect in diabetic CABG patients is unknown., Methods: Eighty-two diabetic patients undergoing CABG were prospectively randomized to aggressive glycemic control (90-120 mg/dL) or moderate glycemic control (120-180 mg/dL) using continuous intravenous insulin solutions (100 units regular insulin in 100 mL: normal saline) beginning at the induction of anesthesia and continuing for 18 hours after CABG. Primary end points were the incidence of major adverse events (major adverse events = 30-day mortality, myocardial infarction, neurologic events, deep sternal infections, and atrial fibrillation), the level of serum glucose, and the incidence of hypoglycemic events., Results: There were no differences in the incidence of major adverse events between the groups (17 moderate vs 15 aggressive; P = 0.91). Patients with aggressive control had a lower mean glucose at the end of 18 hours of insulin infusion (135 ± 12 mg/dL moderate vs 103 ± 17 mg/dL aggressive; P < 0.0001). Patients with aggressive control had a higher incidence of hypoglycemic events (4 vs 30; P < 0.0001)., Conclusions: In diabetic patients undergoing CABG surgery, aggressive glycemic control increases the incidence of hypoglycemic events and does not result in any significant improvement in clinical outcomes that can be achieved with moderate control.

- Abstract
Abstract The purpose of this study was to determine if there was a connection between adherence to antiretroviral therapy (ART) and use of risk reduction behaviors (RRB) in HIV-infected women who were prescribed antiretroviral therapy. The sample consisted of 193 predominately African American women with an average age of 44 who had been on ARV for approximately 9 years and had low annual incomes. All women were participating in a behavioral clinical trial focused on these dual outcomes. Using a risk index developed for this study, we examined the relationship of a composite of risk behaviors to electronically measured and self-reported adherence over the approximately 13-month study period. Women were categorized based on levels of adherence and risky behaviors, and we sought to determine if these classifications were associated with clinical outcomes of HIV viral load and CD4 counts. High levels of adherence were correlated with low risk behaviors (abstinence, consistent use of condoms, etc.). Those classified as high adherence and low-risk behavior (HALR) as well as those classified as high adherence and high-risk behavior (HAHR) had lower mean viral loads and higher CD4 counts than those in the other categories. Women in the low adherence and high-risk category (LAHR) had detectable viral loads and the lowest CD4 counts and are at higher risk for transmitting HIV to partners and unborn children. Our findings underscore the importance of addressing adherence to both ART and RRB in HIV clinical settings to improve clinical outcomes and reduce HIV transmission.

We present the results of a clinical trial that tested the efficacy of using motivational interviewing (MI) in a group format to promote adherence to antiretroviral medications and risk reduction behaviors (RRB) in 203 predominately African American HIV infected women. It was compared to a group health promotion program. Participants were followed for 9 months. Adherence was measured by MEMS(®); and RRB by self-report. Controlling for recruitment site and years on ART, no significant group by time effects were observed. Attendance (≥7/8 sessions) modified the effects. Higher MI attendees had better adherence at all follow-ups, a borderline significant group by time effect (p = 0.1) for % Doses Taken on Schedule, a significantly larger proportion who reported abstinence at 2 weeks, 6, and 9 months, and always used protection during sex at 6 and 9 months. Though not conclusive, the findings offer some support for using MI in a group format to promote adherence and some risk reduction behaviors when adequate attendance is maintained.

- Abstract
Many HIV-positive women regard spirituality as an important part of their lives and spirituality may have positive impact on their health-related quality of life (HRQOL). Particularly among African American women with HIV, spirituality may serve as a cultural and psychological resource. This descriptive, crosssectional study examined associations between spiritual well-being (SWB) and its components, existential well-being (EWB) and religious well-being (RWB), and dimensions of HRQOL among a non-random sample of 118 African American HIV-positive women. A secondary analysis of data from two similar, NIH-funded studies: The Get Busy Living (GBL) Project and the KHARMA Project, was conducted. Baseline data on women from both studies were combined into one database and statistical analyses, including descriptive, correlation and hierarchical regression analyses, were conducted. Existential well-being was significantly positively (β =.74; p=.014) associated with the physical composite of HRQOL and accounted for a significant amount of unique variance (10.0%) beyond that explained by socio-demographic variables, religious well-being (RWB), HIV medication adherence, CD4 cell count and percentage, HIV viral load, and depressive symptoms. EWB was also significantly positively (β =.57; p=.024) associated with the mental health composite of HRQOL. Depressive symptomatology was also significantly inversely (β =.40; p=.004) associated with mental HRQOL. EWB accounted for a significant amount of additional variance (6.3%) beyond that explained by other variables. Spirituality is an important factor in the lives and quality of life of African American women and women living with HIV/AIDS. Further research is needed to examine relationships between spirituality and HRQOL among HIV-positive African American women.

- Abstract
This article reports on the development and psychometric properties of the Antiretroviral General Adherence Scale (AGAS) in two National Institutes of Health-funded projects: the Get Busy Living Project, a behavioral clinical trial to promote consistent use of antiretroviral therapy, and the KHARMA (Keeping Healthy and Active with Risk Reduction and Medication Adherence) Project, which addressed issues of adherence and risk reduction behavior in women. AGAS assesses the ease and ability of participants to take antiretroviral therapy according to a health care provider's recommendations. Data were analyzed from completed baseline assessments of the two studies. The AGAS was internally consistent in both samples. Content, construct, and criterion validity were established using factor analysis and correlations of total AGAS scores with two measures of adherence: electronic drug monitoring and an Adult AIDS Clinical Trials Group adherence scale. Viral load, CD4 cell counts, and depression scores were also examined. Reliability and validity of the AGAS were supported in both samples., (Copyright 2010 Association of Nurses in AIDS Care.

- Abstract
Aim: To identify the palliative care education needs of registered general nurses (RGNs) and health-care assistants (HCAs) working in care of the older person units (nursing homes)., Method: A questionnaire was sent to all RGNs and HCAs working in nursing homes run by the Health Service Executive (HSE) in one health-care region in Ireland., Results: RGNs identified eight specific educational needs: understanding of the dying process; pain and symptom management; improved communication skills; nutritional assessment issues; practical skills; the appropriate use and management of syringe drivers; and the role of complementary therapies. HCAs identified a need to improve their communication skills and clarify their role. Both groups identified the need for support when caring for dying patients and the need to improve their understanding of palliative care and the role of specialist palliative care (SPC) services. There was a significant difference between the RGNs' and the HCAs' level of understanding of palliative care (P = 0.00)., Conclusion: This study demonstrated that RGNs and HCAs working in care of the older person settings have palliative care educational needs. It also established a difference in the educational background and palliative care understanding of RGNs and HCAs. This study therefore identified the need to develop separate education programmes.

- Abstract
Spirituality is a resource some HIV-positive women use to cope with HIV, and it also may have positive impact on physical health. This cross-sectional study examined associations of spiritual well-being, with depressive symptoms, and CD4 cell count and percentages among a non-random sample of 129 predominantly African-American HIV-positive women. Significant inverse associations were observed between depressive symptoms and spiritual well-being (r = -.55, p = .0001), and its components, existential well-being (r = -.62, p = .0001) and religious well-being (r = -.36, p = .0001). Significant positive associations were observed between existential well-being and CD4 cell count (r = .19, p < .05) and also between spiritual well-being (r = .24, p < .05), religious well-being (r = .21, p < .05), and existential well-being (r = .22, p < .05) and CD4 cell percentages. In this sample of HIV-positive women, spiritual well-being, existential well-being, and religious well-being accounted for a significant amount of variance in depressive symptoms and CD4 cell percentages, above and beyond that explained by demographic variables, HIV medication adherence, and HIV viral load (log). Depressive symptoms were not significantly associated with CD4 cell counts or percentages. A significant relationship was observed between spiritual/religious practices (prayer/meditation and reading spiritual/religious material) and depressive symptoms. Further research is needed to examine relationships between spirituality and mental and physical health among HIV-positive women.

Objective: The primary aim of this study was to test a psychosocial model of medication adherence among people taking antiretroviral medications. This model was based primarily on social cognitive theory and included personal (self-efficacy, outcome expectancy, stigma, depression, and spirituality), social (social support, difficult life circumstances), and provider (patient satisfaction and decision-making) variables., Design: The data for this analysis were obtained from the parent study, which was a randomized controlled trial (Get Busy Living) designed to evaluate an intervention to foster medication adherence. Factor analysis was used to develop the constructs for the model, and structural equation modeling was used to test the model. Only baseline data were used in this cross sectional analysis., Methods: Participants were recruited from a HIV/AIDS clinic in Atlanta, GA. Prior to group assignment, participants were asked to complete a questionnaire that included assessment of the study variables. Results A total of 236 participants were included in the analysis. The mean age of the participants was 41 years; the majority were male, and most were African-American. In the final model, self-efficacy and depression demonstrated direct associations with adherence; whereas stigma, patient satisfaction, and social support were indirectly related to adherence through their association with either self-efficacy or depression., Conclusion: These findings provide evidence to reinforce the belief that medication-taking behaviors are affected by a complex set of interactions among psychosocial variables and provide direction for adherence interventions.

- Abstract
Women comprise the fastest growing group of persons with AIDS. They are often diagnosed later in the disease, when antiretroviral therapy (ART) is strongly indicated. Antiretroviral therapy has transformed the course of HIV/AIDS to a treatable, chronic illness. This article provides a profile of women with HIV/AIDS and describes ART. Selected research related to adherence and motivation is summarized. Psychosocial and economic concerns specific to women, ART, adherence, and motivation are presented. The article reviews challenges for risk reduction behaviors for HIV+ women, such as sexual activity and substance abuse. The authors discuss the Keeping Health and Active with Risk reduction and Medication Adherence (KHARMA) Project, a research project in progress that was designed to promote adherence to both ART and risk reduction behaviors in HIV+ women. The study includes two groups: a motivational group intervention based on motivational interviewing and a health promotion program control group tailored to the needs of HIV+ women. A description of the tailored intervention and project update is included.

- Abstract
Twenty-one open pollinated populations of peach rootstock seedlings were evaluated for their response to infection by the root lesion nematode, Pratylenchus penetrans, over a period of 98 days. Nematode-infected peach seedling populations were shorter in plant height and had less shoot weight but more dry root weight than nematode-free controls. Rootstock differences were demonstrated for nematode increase over the 98-day period, and average total numbers of nematodes in soil and roots. Rootstocks were classified into three groups differing in total nematode population levels, ratio of nematode increase, and the number of nematodes per root. The heritable nature of rootstock response to nematodes was evident. Rootstocks showing the lowest response to nematode infection included Tzim Pee Tao, Rutgers Red Leaf, and two progenies of a cross of these two rootstocks.

- Abstract
Each of the nurses in these examples demonstrates an understanding of patient advocacy. Patient advocacy may involve the nurse in political action or negotiation for change. Perhaps more frequently, however, it is a quiet, private function of support and intuition as patients (or clients) seek to come to a personal awareness of the meaning of illness. Advocacy exhibits a sensitivity to personal values, hopes, and even unspoken prayer that shape an atmosphere of caring. Patient advocacy enhances all that is life giving.
