Abstract
BACKGROUND Women face unique complexities in HIV treatment yet are underrepresented in antiretroviral therapy (ART) studies. OBJECTIVE This analysis assessed the one-year durability of the first integrase strand transfer inhibitor (INSTI)-based regimens prescribed to women in a large cohort of patients living with HIV in care. METHODS Women with HIV who initiated their first INSTI-containing regimen between 08/12/2013 and 11/30/2015 were identified in the OPERA cohort, a collaboration of 79 US outpatient clinics. Discontinuation within the first year of treatment with an INSTI was compared between dolutegravir (DTG), raltegravir (RAL) and elvitegravir (EVG), using multivariable Cox regression and Kaplan- Meier estimates. Virologic response and regimen modifications were described and compared across INSTIs. RESULTS A total of 537 treatment-naïve (DTG: 39%, EVG: 48%, RAL: 13%) and 878 treatmentexperienced (DTG: 57%, EVG: 29%, RAL: 13%) women were analyzed. In the first twelve months after initiation, women taking EVG or RAL were more likely to discontinue their initial INSTI than those taking DTG among both treatment-naïve (adjusted hazard ratio EVG vs. DTG: 1.59 (95% CI: 1.09, 2.39); RAL vs. DTG: 2.46 (1.49, 4.05)) and treatment-experienced women (EVG vs. DTG: 1.39 (1.02, 1.88); RAL vs. DTG: 2.17 (1.51, 3.12)). Following discontinuation of the initial INSTI, women commonly switched to a regimen containing a different drug from the INSTI class (treatment-naïve DTG: 34%, RAL: 33% EVG: 41%; treatment-experienced DTG: 23%, RAL: 19% EVG: 41%). CONCLUSION In treatment-naïve and treatment-experienced women living with HIV, women taking DTG had the lowest risk for early (≤1 year) discontinuation.

Abstract
Entering HIV care is a vulnerable time for newly diagnosed individuals often exacerbating psychosocial difficulties, which may contribute to poor health-related quality of life (HRQOL) ultimately influencing health behaviors including ART adherence, the driver of viral load suppression. Understanding HRQOL in people newly entering HIV care is critical and has the potential to guide practice and research. This exploratory cross-sectional study examined demographic, clinical, and psychosocial factors associated with limitations in four specific domains of HRQOL among persons initially entering outpatient HIV care at four sites in the United States (n = 335). In the unadjusted analysis, female gender was significantly associated with sub-optimal HRQOL with women having increased odds of reporting HRQOL challenges with pain, mood, mobility, and usual activity when compared to men. The adjusted models demonstrated attenuation of parameter estimates and loss of statistical significance for the associations with impaired HRQOL observed among women in unadjusted analyses, suggesting psychosocial factors related to HRQOL are complex and interrelated. Findings are consistent with a robust literature documenting gender-related health disparities. Programs aimed at improving HRQOL for persons initially entering HIV care are warranted generally, and specifically for women, and must address modifiable psychosocial factors via mechanisms including coping and social support.

Abstract
Despite the issuance of evidence-based and evidence-informed guidelines to improve engagement in HIV care and adherence-related outcomes, few studies have assessed contemporary adherence or engagement support practices of HIV care providers in US clinics. As a result, the standard of HIV care in the US and globally remains poorly understood. This programmatic assessment approach aimed to identify the strengths and gaps in the current standard of HIV care from the perspective of HIV care providers. A self-administered Standard of Care measure was developed and delivered through Qualtrics to HIV care providers at four different HIV care sites as a part of a multisite intervention study to improve engagement in HIV care and ART adherence. Providers were asked to provide demographic and clinic specific information, identify practices/strategies applied during typical initial visits with HIV-positive patients and visits prior to and at ART initiation, as well as their perceptions of patient behaviors and adequacy of HIV care services at their clinics. Of the 75 surveys which were completed, the majority of respondents were physicians, and on average, providers have worked in HIV care for 13.5 years. Across the sites, 91% of the providers' patient panels consist of HIV-positive patients, the majority of whom are virally suppressed and 1/5 are considered "out of care." Few resources were routinely available to providers by other staff related to monitoring patient adherence and engagement in care. During typical initial visits with HIV positive patients, the majority of providers report discussing topics focused on behavioral/life contexts such as sexual partnerships, sexual orientation, disclosure, and other sources of social support. Nearly all providers emphasize the importance of adherence to treatment recommendations and nearly 90% discuss outcomes of good adherence and managing common side effects during ART start visits. Overall, providers do not report often implementing practices to improve retention in care. Survey results point to opportunities to enhance engagement in HIV care and improve ART adherence through systematic data monitoring and increased collaboration across providers and other clinic staff, specifically when identifying patients defined as "in need" or "out of care." Trial Registration: Clinicaltrials.gov NCT01900236.

Abstract
Ensuring continuity of and retention in care after release from prison is critical for optimizing health outcomes among people living with HIV. As part of a large federal initiative, we conducted qualitative interviews (n = 24) with individuals living with HIV and recently released from prison in four states to understand their experiences in different navigation interventions to improve access to HIV care post-release. Interventions were delivered only in prison, only in the community, or in both settings. While the interventions varied by design, overall, participants appreciated the breadth of support received from interventionists, including health system navigation, case management and social support. Even when individuals leaving prison were returning to clinics that they were familiar with, systems navigation supported continuity of care. Our findings elucidate why navigational support was instrumental, and underscore the value of a variety of types of navigation programs in facilitating continuity of care and reintegration post-prison.

Abstract
Social networks can be leveraged to identify undiagnosed HIV-infected individuals. The NC-LINK clinic-based testing initiative utilized these networks to achieve a 5% (95% CI 1.1-8.9%) positivity rate by providing free HIV testing to anyone who accompanied an HIV-infected patient to their clinic appointment. During 2013-2015, 120 individuals were tested at two clinics (N > 1000 patients each) in North Carolina, with 5 new and 6 total positive results. Of these, three linked to care within 30 days and all within 365 days. If expanded further, this initiative could significantly increase the number of HIV-infected individuals aware of their status.

Abstract
Engagement in HIV care is critical to achieve viral suppression and ultimately improve health outcomes for people living with HIV (PLWH). However, maintaining their engagement in care is often a challenging goal. Utilizing patient navigators, trained in an adapted ARTAS intervention, to help re-engage out-of-care PLWH has proven to be a valuable resource. This qualitative study describes the encounters between PLWH (n = 11) and their care re-engagement navigators (n = 9). Participants were interviewed in-person; interviews were transcribed and analyzed using the strengths model of case management. PLWH shared how working with navigators increased their motivation to return to HIV care and assisted them to overcome barriers that were a hindrance to care engagement. Navigators described a strengths-based approach to working with their clients, thus helping facilitate PLWH care re-engagement goals and successes. Results from this study may inform the development of effective HIV navigation programs to re-engage out-of-care PLWH, often the hardest-to-engage.

Abstract
BACKGROUND Statewide interventions are critical to meeting the goals of the National HIV/AIDS Strategy in this country. In 2012, the North Carolina Division of Public Health developed the North Carolina State Bridge Counselor program to improve linkage to and reengagement in care for newly diagnosed persons and persons living with HIV who were out-of-care.METHODS We reviewed the planning process for the North Carolina State Bridge Counselor program, which involved a review of existing strengths-based counseling models for persons living with HIV, implementation of these models, and communication strategies with other providers. State bridge counselor responsibilities were delineated from the role of disease intervention specialists while retaining the fieldwork capability of disease intervention specialists to conduct outreach and provide services for persons living with HIV throughout the state.RESULTS Program implementation required extensive planning with stakeholders, incorporation of strengths-based counseling models, development of performance standards, and utilization of CAREWare, an HIV care software program to document referrals and data-sharing between state bridge counselors and clinics. By the end of 2014, state bridge counselor services were provided to approximately 60 of the 400 persons living with HIV (15%) who are diagnosed each quarter in North Carolina, with increasing utilization of the program.LIMITATIONS We assessed the development of this intervention specific to the North Carolina Division of Public Health, which may limit its generalizability. However, the State Bridge Counselor program was implemented in both urban and rural areas throughout the state, which increases its applicability to different public health programs throughout the country.CONCLUSION We demonstrated that a statewide State Bridge Counselor program for linkage and reengagement activities can be implemented by leveraging existing infrastructures, electronic medical records, HIV care networks, and fieldwork activities.

Abstract
Poor retention in care is associated with higher viral load (VL) results and decreased rates of viral load suppression (VS) in people living with HIV (PLWH). Therefore, improving retention in HIV care is a priority of national significance. The NC-LINK Retention Project utilized a systematic approach to identify, locate, and attempt to return to care patients who did not attend a clinic appointment for 6-9 months. Clinical and surveillance data were used to evaluate associations between patient characteristics and VL outcomes. Between January 1, 2013 and December 31, 2014, 1118 patients at participating clinics were identified as out-of-care and referred to retention staff. Of these, 712 (64%) were located in North Carolina. Patients with recent prior medical care (aPR 1.43, 95% CI 1.25, 1.66) and recent VS (aPR 1.28, 95% CI 1.16, 1.41) were more likely to be located. Of located patients, 58% re-engaged in care within 90 days of retention referral. Patients who achieved VS within 180 days were more likely to be 40-49 years (aPR 1.19 95% CI 1.01-1.40; compared with 18-29 age group), had insurance at their last visit (aPR 1.19 95% CI 1.01-1.77), had a care visit in the prior year (aPR 1.37 95% CI 1.05-1.77), and had VS at the prior care visit (aPR 2.54 95% CI 1.98-3.25). Clinic-based retention efforts may be effective at helping PLWH decrease out-of-care periods, but prior patterns of care usage persist.

Abstract
During the initial year of HIV diagnosis, while patients are often overwhelmed adjusting to this life changing diagnosis, they must develop self-care behaviors for attending regular medical care visits and antiretroviral therapy (ART) adherence to achieve and sustain viral suppression (VS). Maintaining "HIV adherence" and integrating it into one's daily life is required to sustain VS over time. The HIV care continuum or "treatment cascade," an epidemiological snapshot of the national epidemic in the United States (US), indicates that a minority of persons living with HIV (PLWH) have achieved VS. Little evidence exists regarding the effects of interventions focusing on PLWH newly initiating outpatient HIV care. An intervention that focuses on both retention in care and ART adherence skills delivered during the pivotal first year of HIV care is lacking. To address this, we developed a theory-based intervention evaluated in the Integrating Engagement and Adherence Goals upon Entry (iENGAGE) study, a National Institute of Allergy and Infectious Diseases (NIAID) funded randomized behavioral intervention trial. Here we present the study objectives, design and rationale, as well as the intervention components, targeting rapid and sustained VS through retention in HIV care and ART adherence during participants' first year of HIV care. The primary outcome of the study is 48-week VS (<200 c/mL). The secondary outcomes are retention in care, including HIV visit adherence and visit constancy, as well as ART adherence.

Abstract
OBJECTIVE The aim of this study was to determine active periodontal disease status in HIV and to determine the impact of periodontal disease resolution on HIV status. METHODS In this longitudinal cohort study, 73 HIV-positive subjects received comprehensive dental care. AAP, CDC/AAP, and BGI case definitions determined periodontal classification. Likelihood and frequency of moderate/severe periodontal disease were assessed based on demographic variables. The influence of periodontal intervention was assessed at baseline, 12, and 24 months. IL-6 was measured in a subset of subjects. RESULTS Of the periodontal classifications, BGI demonstrated the highest percentage category improvement with the intervention (>50%). Moderate/severe periodontitis was positively associated with HIV regardless of race, smoking status, gender, income level, and age, and was associated with increased IL-6. At baseline, the majority of subjects had severe periodontal disease regardless of ART status. Subjects with suppressed viral load at baseline demonstrated a significant improvement in BGI classification (P = 0.026), increased CD4 counts (P = 0.027), and decreased IL-6 levels (P = 0.03). CONCLUSIONS Periodontal inflammation was prevalent regardless of ART status. In virologically suppressed subjects, the intervention decreased periodontitis with a concomitant IL-6 decrease and CD4 increase. These findings suggest a relationship between periodontal inflammation, oral microbial translocation, and HIV status.

Abstract
Only 80% of people living with HIV (PLWH) in the United States are linked to care, 40% are engaged in care, and 30% have achieved viral load suppression. We addressed linkage to care with a pilot program of a statewide referral call center to connect PLWH and their non-HIV specialty providers to HIV care. Callers received tailored referrals from nurses trained to work in an existing call center, using an electronic assessment tool and a comprehensive HIV provider list. Of 122 calls, 85% were from PLWH and 15% from providers calling about a patient. Overall, 88 of 104 (84.6%) PLWH and 16 of 18 (88.9%) providers accepted care referral, including 13% of PLWH callers without prior HIV care. Results indicated that the call center was an acceptable strategy for HIV care referral; the use of an existing call center facilitated feasibility of the program and improved linkage to HIV care.

Abstract
Background Meticulous tracking of study data must begin early in the study recruitment phase and must account for regulatory compliance, minimize missing data, and provide high information integrity and/or reduction of errors. In behavioral intervention trials, participants typically complete several study procedures at different time points. Among HIV-infected patients, behavioral interventions can favorably affect health outcomes. In order to empower newly diagnosed HIV positive individuals to learn skills to enhance retention in HIV care, we developed the behavioral health intervention Integrating ENGagement and Adherence Goals upon Entry (iENGAGE) funded by the National Institute of Allergy and Infectious Diseases (NIAID), where we deployed an in-clinic behavioral health intervention in 4 urban HIV outpatient clinics in the United States. To scale our intervention strategy homogenously across sites, we developed software that would function as a behavioral sciences research platform. Objective This manuscript aimed to: (1) describe the design and implementation of a Web-based software application to facilitate deployment of a multisite behavioral science intervention; and (2) report on results of a survey to capture end-user perspectives of the impact of this platform on the conduct of a behavioral intervention trial. Methods In order to support the implementation of the NIAID-funded trial iENGAGE, we developed software to deploy a 4-site behavioral intervention for new clinic patients with HIV/AIDS. We integrated the study coordinator into the informatics team to participate in the software development process. Here, we report the key software features and the results of the 25-item survey to evaluate user perspectives on research and intervention activities specific to the iENGAGE trial (N=13). Results The key features addressed are study enrollment, participant randomization, real-time data collection, facilitation of longitudinal workflow, reporting, and reusability. We found 100% user agreement (13/13) that participation in the database design and/or testing phase made it easier to understand user roles and responsibilities and recommended participation of research teams in developing databases for future studies. Users acknowledged ease of use, color flags, longitudinal work flow, and data storage in one location as the most useful features of the software platform and issues related to saving participant forms, security restrictions, and worklist layout as least useful features. Conclusions The successful development of the iENGAGE behavioral science research platform validated an approach of early and continuous involvement of the study team in design development. In addition, we recommend post-hoc collection of data from users as this led to important insights on how to enhance future software and inform standard clinical practices.

Abstract
The levels of satisfaction of the core self-determination needs (relatedness, autonomy and competence) among HIV-infected women of color as well as the association between need fulfillment and patient characteristics were examined. Having less than a high-school education was associated with lowest need satisfaction: autonomy (β = -1.90; 95%CI = -3.20, -0.60), relatedness (β = -2.70; 95%CI = -4.30, -1.10) and competency (β = -2.50; 95%CI = -3.60, -1.30). Each additional point increase in affective symptoms of depression was associated with decrements in need satisfaction (-.61 autonomy, -.68 relatedness and -.59 competency). Relatedness satisfaction was lower with higher responses on all three measures of violence (psychological abuse: β = -0.13, 95%CI = -0.19 to -0.07; adult traumatic experiences: β = -0.24, 95%CI = -0.35 to -0.13 and childhood traumatic experiences: β = -0.24, 95%CI = -0.40 to -0.08). Interventions that address core self-determination needs, and the characteristics that influence them, may enhance the motivation for self-care of HIV-infected women.

Abstract
Decreased visit attendance leads to poor health outcomes, decreased viral suppression, and higher mortality rates for persons living with HIV. Retention in care is an important factor in improving health status for people living with HIV but continues to be a challenge in clinical settings. This paper details the development and implementation of the NC-LINK Retention Protocol, a clinic-based protocol to locate and reengage out-of-care patients, as part of overall clinic retention efforts. The protocol was implemented as one of four interventions of the NC-LINK Systems and Linkages Project, a multi-site initiative funded by the HIV/AIDS Bureau and the Special Projects of National Significance. Lists of out-of-care patients who had not received HIV medical care in over nine months and did not have a future appointment were created each month. Patient navigators, case managers, and other staff then followed a standardized protocol to locate and reengage these patients in care. A total of 452 patients were identified for reengagement services. Of those, 194 (43%) returned to care, 108 (24%) had another definitive outcome (incarcerated, deceased, or relocated) and 150 (33%) were referred for additional follow-up to locate and reengage in care. In summary, 67% of patients were located through the efforts of the clinic staff. The results of this intervention indicate that it is possible to successfully integrate a protocol into the existing infrastructure of a clinic and reengage a majority of out-of-care patients into medical care.

Abstract
BACKGROUND HIV testing and linkage to care are critical first steps along the care continuum. Targeted efforts are needed in the South to achieve the goals of the National HIV/AIDS Strategy, and qualitative examination of testing and linkage to care from the perspective of professionals in the field can provide nuanced insight into the strengths and limitations of a care system to inform improvement efforts. These issues are explored in North Carolina (NC), with potential applicability to other Southern states. METHODS Twenty-one interviews were conducted with professionals in the HIV prevention and care systems in NC. Interviews were analyzed for emergent themes. RESULTS Individuals' access barriers, aspects of clinics and clinical care, challenges for community-based organizations, stigma, and the role of the NC Department of Health and Human Services were identified as themes affecting testing and linkage. DISCUSSION These findings can inform efforts to address HIV testing and linkage to care in NC. This approach may provide beneficial insight for other systems of care.

Abstract
Retention in HIV care is critical to decrease disease-related mortality and morbidity and achieve national benchmarks. However, a myriad of barriers and facilitators impact retention in care; these can be understood within the social-ecological model. To elucidate the unique factors that impact consistent HIV care engagement, a qualitative case study was conducted in North Carolina to examine the barriers and facilitators to retain and reengage HIV clients in care. HIV professionals (n = 21) from a variety of health care settings across the state participated in interviews that were transcribed and analyzed for emergent themes. Respondents described barriers to care at all levels within the HIV prevention and care system including intrapersonal, interpersonal, institutional, community, and public policy. Participants also described recent statewide initiatives with the potential to improve care engagement. Results from this study may assist other states with similar challenges to identify needed programs and priorities to optimize client retention in HIV care.

Abstract
BACKGROUND Infectious diseases (ID) clinics are locations where members of at risk social networks, including sex partners of HIV-infected patients, make contact with a medical care setting when they accompany HIV-positive patients to appointments. METHODS We implemented a free point-of-care rapid HIV testing program for anyone accompanying a patient to the University of North Carolina ID clinic. Acceptability of the program among the general clinic population was assessed via an anonymous survey 1 year after program implementation. Basic frequencies of those who underwent and received results of rapid HIV testing, the proportion of positive rapid tests and confirmatory HIV tests performed, and the level of University of North Carolina ID clinic patient satisfaction with the HIV testing program were calculated. RESULTS Between October 2007 and June 2013, 450 (99.6%) of 452 individuals tested in the program received their results on the same day as testing. Twenty-two individuals (4.9%) tested HIV positive, of which 16 (72.7%) were newly positive, including 3 never previously tested. Excluding previously diagnosed individuals, HIV prevalence was 3.6% (16/446). Among those testing positive by rapid testing, 19 (86.4%) had confirmatory testing and immediately entered into HIV care at the clinic. CONCLUSIONS The high positivity and confirmatory HIV rates in our program confirm that the provision of rapid HIV testing in an ID clinic capitalizes on missed opportunities among an at-risk population and allows immediate linkage to care.

Abstract
Irregular participation in HIV medical care hinders HIV RNA suppression and impacts health among people living with HIV. Cluster analysis of clinical data from 1,748 patients attending a large academic medical center yielded three HIV service usage patterns, namely: 'engaged in care', 'sporadic care', and 'frequent use'. Patients 'engaged in care' exhibited most consistent retention (on average, >88 % of each patient's observation years had ≥2 visits 90 days apart), annualized visit use (2.9 mean visits/year) and viral suppression (>73 % HIV RNA tests <400 c/mL). Patients in 'sporadic care' demonstrated lower retention (46-52 %), visit use (1.7 visits/year) and viral suppression (56 % <400 c/mL). Patients with 'frequent use' (5.2 visits/year) had more inpatient and emergency visits. Female, out-of-state residence, low attendance during the first observation year and detectable first-observed HIV RNA were early predictors of subsequent service usage. Patients 'engaged in care' were more likely to have HIV RNA <400 than those receiving sporadic care. Results confirm earlier findings that under-utilization of services predicts poorer viral suppression and health outcomes and support recommendations for 2-3 visits/year.

Abstract
The prevalence of depression is 20%-30% for people living with HIV, and while it is associated with poorer adherence to antiretrovirals, it is often unrecognized by medical providers. Although it has been challenging for some health care settings to develop consistent depression screening mechanisms, it is feasible to create screening protocols using the nine-item Patient Health Questionnaire (PHQ-9). Establishing a depression screening and response protocol is an iterative process that involves preparing staff, determining screening frequency, and developing procedures for response and appropriate medical record documentation. While there are multiple issues and potential challenges during implementation, it is possible to incorporate systematic depression screening into HIV primary care in a manner that achieves staff buy-in, minimizes patient burden, streamlines communication, and efficiently uses the resources available in the medical setting.

Abstract
Background Adherence with medication regimens for human immunodeficiency virus (HIV) is a life-saving behavior for people with HIV infection, yet adherence is challenging for many individuals with co-occurring substance use and/or mood disorders. Medication-taking self-efficacy, which is the confidence that one can take one’s medication as prescribed, is associated with better adherence with HIV medication. However, little is known about the influence that other kinds of self-efficacy have on adherence with HIV medication, especially among HIV-infected individuals with co-occurring substance use and/or mood disorders. We sought to examine the relationship between adherence with HIV medication among substance users and three specific kinds of self-efficacy, ie, one’s confidence that one can communicate with medical providers, get support, and manage one’s mood. We further sought to examine whether symptoms of depression and anxiety moderate these relationships. Methods Patients were recruited from three HIV clinics in the southeastern United States as part of an integrated study of treatment for HIV and substance use. Results We interviewed 154 patients with HIV and substance use who reported taking HIV medications. Based on symptoms of depression and anxiety using the Patient Health Questionnaire-9 and the Hospital Anxiety and Depression Scale-Anxiety, 63% had probable depression and/or anxiety. Higher levels of self-efficacy in provider communication (β = 3.86, P < 0.01), getting needed support (β = 2.82, P < 0.01), and mood management (β = 2.29, P < 0.05) were related to better self-reported adherence with HIV medication among study participants with probable depression and/or anxiety. The three kinds of self-efficacy were not associated with medication adherence among participants with HIV and substance use only. Conclusion In the search for mutable factors to improve medication adherence among individuals triply diagnosed with HIV, substance use, and mood disorders, these findings support previous research indicating the benefit of enhancing self-efficacy, and further point to three specific kinds of self-efficacy that may benefit medication adherence, ie, provider communication, getting support, and mood management.

Abstract
BACKGROUND To assess factors associated with having a Trichomonas vaginalis (TV) infection among persons receiving care for human immunodeficiency virus (HIV) and estimate the number of transmitted HIV infections attributable to TV. METHODS HIV clinic patients were recruited from 2 secondary prevention studies, screened by urine nucleic-acid amplification tests for sexually transmitted infections, and interviewed about risk factors (baseline, 6, and 12 months). We conducted mathematical modeling of the results to estimate the number of transmitted HIV infections attributable to TV among a cohort of HIV-infected patients receiving medical care in North Carolina. RESULTS TV was prevalent in 7.4%, and incident in 2% to 3% of subjects at follow-up. Individuals with HIV RNA <400 copies/mL (odds ratio, 0.32; 95% CI: 0.14-0.73) and at least 13 years of education (odds ratio, 0.24; 95% CI: 0.08-0.70) were less likely to have TV. Mathematical modeling predicted that 0.062 HIV transmission events occur per 100 HIV-infected women in the absence of TV infection and 0.076 HIV infections per 100 HIV- and TV-infected women (estimate range: 0.070-0.079), indicating that 23% of the HIV transmission events from HIV-infected women may be attributable to TV infection when 22% of women are coinfected with TV. CONCLUSIONS The data suggest the need for improved diagnosis of TV infection and suggest that HIV-infected women in medical care may be appropriate targets for enhanced testing and treatment.

Abstract
Co-occurrence of HIV and substance abuse is associated with poor outcomes for HIV-related health and substance use. Integration of substance use and medical care holds promise for HIV patients, yet few integrated treatment models have been reported. Most of the reported models lack data on treatment outcomes in diverse settings. This study examined the substance use outcomes of an integrated treatment model for patients with both HIV and substance use at three different clinics. Sites differed by type and degree of integration, with one integrated academic medical center, one co-located academic medical center, and one co-located community health center. Participants (n=286) received integrated substance use and HIV treatment for 12 months and were interviewed at 6-month intervals. We used linear generalized estimating equation regression analysis to examine changes in Addiction Severity Index (ASI) alcohol and drug severity scores. To test whether our treatment was differentially effective across sites, we compared a full model including site by time point interaction terms to a reduced model including only site fixed effects. Alcohol severity scores decreased significantly at 6 and 12 months. Drug severity scores decreased significantly at 12 months. Once baseline severity variation was incorporated into the model, there was no evidence of variation in alcohol or drug score changes by site. Substance use outcomes did not differ by age, gender, income, or race. This integrated treatment model offers an option for treating diverse patients with HIV and substance use in a variety of clinic settings. Studies with control groups are needed to confirm these findings.

Abstract
Substance use disorders are common among people living with HIV (PLWHA), and PLWHA with untreated substance use are less likely to receive antiretroviral therapy (ART) or achieve viral suppression when ART is prescribed. Integrated behavioral and medical interventions are one approach used to treat complex chronic illnesses, including HIV and substance abuse (SA). As the potential benefit for integrated HIV-substance abuse treatment is recognized, the number of providers attempting to integrate care is growing. Integrated care models can range from coordinated to colocated to fully integrated models. Providers need a better understanding of these implementation options for HIV-substance abuse treatment and how they impact providers of different disciplines. Between April and November 2006, interviews exploring the process of implementing an integrated HIV-substance abuse intervention were completed with clinic staff at three diverse HIV clinics in North Carolina. Key differences in implementation between sites were found. The degree of integrated care between sites ranged from colocated to integrated, and clinic staff perceived each integrated model to have advantages and disadvantages. Recommendations for implementing HIV-SA integrated care are made.

Abstract
The relationship between viral infection with Kaposi sarcoma-associated herpesvirus (KSHV) and the onset of Kaposi sarcoma (KS) in AIDS patients is incompletely understood. This study investigates the use of three serological assays to predict the development of KS in HIV-positive patients. Serially collected serum samples from 36 patients with KS and matched controls in the Swiss HIV Cohort Study (SHCS) were analyzed in a case control study. Three serologic assays to detect antibodies against KSHV (nuclear and membrane antigen immunofluorescence assay, N-IFA, M-IFA and ORF 65.2 ELISA) were used to determine the predictive value of KSHV-seropositivity. Serial samples from the cases were also analyzed to determine longitudinal patterns of seroreactivity and identify cases of seroconversion. Assay sensitivity for detection of KSHV antibodies was highest for M-IFA (83%), followed by N-IFA (74%) and 65.2 ELISA (52%). At the time of initial serum sampling (median 4.7 years before KS), only the N-IFA distinguished case and control sera (61% vs. 32%) and no assay was clearly predictive of subsequent onset of clinical KS. Moreover, an unexpectedly high rate of reversions to seronegativity were observed by N-IFA (27/33) as well as by 65.2 ELISA (11/26) in the longitudinal analysis. Analysis of the ORF65.2 ELISA index indicated that these reversions before the clinical onset of KS were associated with antibody levels that frequently hovered around the level of detectability. A marked increase in ORF 65.2 antibody titer occurred in a third of the patients at the time of KS diagnosis. Only two seroconversions were documented. KSHV infection within the SHCS is likely to have preceded HIV infection. KSHV infection alone is not highly predictive of KS development in this cohort of HIV-infected homosexual men as compared with matched controls. Three KSHV serologic assays, though sensitive at the time of clinical KS are inconsistently positive before the development of AIDS-related KS.

Abstract
The ORF50 gene of Kaposi's sarcoma (KS)-associated herpesvirus, or human herpesvirus 8 (KSHV), activates viral replication and is weakly homologous to the herpesvirus family of R transactivators; therefore, the transcription and translation events from this region of KSHV are key events in viral reactivation. We demonstrate that ORF50 is expressed in a bicistronic message after induction of the viral lytic cycle. ORF50 migrated as a series of polypeptides: the major ones as 119 and 101 kDa, respectively. Using 3' rapid amplification of cDNA ends, RT-PCR, and cDNA library screening, we demonstrate that the major ORF50 transcript also encodes K8. The ORF50/K8 transcript was resistant to cyclohexamide, whereas the K8 transcript was only partially resistant to cyclohexamide at early timepoints. Both transcripts showed partial resistance after 12 h of phorbol ester induction. Using a GAL4-ORF50 fusion protein expression vector, we demonstrate that the transactivation domain of ORF50 resides within a 160-amino-acid region of the carboxyl portion of the ORF. Upstream regions of both ORF50 and K8 have basal promoter activity in KSHV-infected cells. K8, which had sequence homology to Bzip proteins, did not activate either promoter. However, both promoters were activated after cotransfection of ORF50 in BCBL-1 cells.

Abstract
The prevalence of Epstein-Barr virus (EBV) and the recently identified Kaposi's sarcoma (KS)-associated herpesvirus (also designated human herpesvirus 8 [HHV-8]) was determined in oral lesions and oral neoplasms common to persons with human immunodeficiency virus (HIV) infection. Oral lesions were examined by polymerase chain reaction (PCR) for EBV and HHV-8 DNA and by Southern blot analysis for EBV clonality. EBV was detected by Southern blot in hairy leukoplakia lesions, in a subset of AIDS-related lymphomas, and in saliva from HIV-positive persons but not in pseudohairy leukoplakia lesions, oral aphthous ulcers, or oral KS lesions. EBV was detected, however, by PCR in most of the lesions, while HHV-8 was detected only in oral KSs. The absence of HHV-8 DNA in both the EBV-associated hairy leukoplakia lesions and in the EBV-associated AIDS-related lymphomas strengthens the etiologic relationship of EBV to these pathologies and the etiologic role of HHV-8 in KS.

Abstract
Human herpevirus 8 (HHV8) has been localized to the endothelial and spindle cells of KS, suggesting a role for HHV8 in atherosclerosis. None of the 38 coronary atherectomy specimens contained HHV8 with both sensitive nested PCR assays, making it unlikely that persistent viral infection with HHV8 plays a role in coronary atherogenesis in the general population of the United States.

Abstract
Substantial evidence indicates a causal role for human papillomavirus (HPV) infection in the development of cervical dysplasia and cancer. However, since recent advances in HPV detection techniques indicate that genital HPV infection among women is common, it is clear that transient HPV infection is not sufficient for development of cervical malignancy. Oncogenesis may require persistent infection as well as the presence of cofactors that are not yet completely understood. The role of HPV detection and typing in clinical management of HPV-associated lesions is currently being investigated.

Abstract
Epstein-Barr virus (EBV) is associated with the development of several types of human cancers and is an important cause of lymphomas in immunocompromised hosts. Expression of the EBV BZLF1 immediate-early gene product (Z) triggers disruption of latency in EBV-infected cells. Z is a member of the b-Zip family of proteins and binds to AP-1-like sites in early viral promoters. Here we show that a viral RNA related to Z, in which there is replacement of the transactivation domain of Z by fusion through alternate splicing with a portion of another EBV transactivator, BRLF1 (R), can repress Z function. This differentially spliced mRNA is predicted to express a novel chimeric protein which we call RAZ for R and Z. RAZ retains the dimerization and DNA-binding domains of Z but loses its transactivation domain. We show that in vitro the RAZ protein acts transdominantly to repress transactivation of early promoters by Z. Repression is produced by dimerization of RAZ with Z resulting in RAZ:Z heterodimers that can no longer bind to Z-binding sites despite retention of the DNA-binding domains in both proteins. Deletion of the R domain of RAZ restores the ability of the truncated RAZ homodimers and RAZ:Z heterodimers to bind to DNA. A biologic effect of RAZ was shown by cotransfection of latently infected Raji cells with Z and RAZ expression clones; RAZ diminished viral reactivation induced by Z, as indicated by amount of early replicative antigens (EA-D) detected. The RAZ protein presents a model for transcriptional control unique among the herpesvirus and distinct from analogous viral and cellular repressors. RAZ, by limiting the availability of Z protein, is likely to modulate EBV reactivation.

Abstract
Disruption of Epstein-Barr virus (EBV) latency is mediated through the activation of the viral immediate-early proteins, BZLF1 (Z) and BRLF1 (R).i.; (Chevallier-Greco, A., et al., (1986) EMBO J., 5, 3243-9; Countryman, and Miller, G. (1985) Proc. Natl. Acad. Sci. USA, 82, 4085-4089). We have previously demonstrated that these proteins cooperatively activate the EBV early promoter BMRF1 in lymphoid cells but not in epithelial cells. Although cooperative transactivation by these proteins has been demonstrated with a number of EBV promoters, the mechanism of this interaction is not well understood. We now show that the cooperative activation of the BMRF1 promoter by Z-plus-R requires an intact R binding site and at least one functional Z response element (ZRE). Despite the presence of an R binding site, the BMRF1 promoter is only moderately responsive to R alone in either HeLa or Jurkat cells. Efficient activation of the BMRF1 promoter by Z alone in HeLa cells requires two ZREs (located at -59 and -106), whereas two additional Z binding sites (located at -42 and -170) contribute very little to Z-induced activation. In the absence of ZREs, Z acted as a repressor of R-induced transactivation. These observations, along with observations made by other investigators (Giot, J.F. et al., (1991) Nucleic Acids Res., 19, 1251-8), suggest that Z-plus-R cooperative activation is dependent upon 1) direct binding by R and Z to responsive promoter elements and 2) contributions by cell-specific factors.

Abstract
Immunocompromised patients, particularly those with AIDS, develop progressive multifocal leukoencephalopathy (PML) due to central nervous system infection with JC virus (JCV). It is unknown whether JCV infection in the central nervous system can occur in the absence of PML symptoms. To address this question, autopsy specimens from patients with AIDS were examined. The brains of a group of patients without AIDS or central nervous system disease were also examined. JCV DNA was detected by the polymerase chain reaction in brain tissue from 4 (31%) of 13 human immunodeficiency virus (HIV)-positive patients. JCV was also detected in 1 elderly HIV-negative patient but not in the 11 other control brains. JCV was not detected in 22 myocardial specimens obtained at autopsy from HIV-negative patients nor 10 peripheral blood specimens from HIV-positive patients. The presence of JCV in brains of patients without clinically evident PML suggests that JCV may be present in the central nervous system without clinical disease.

Abstract
Regulation of replicative functions in the Epstein-Barr virus (EBV) genome is mediated through activation of a virally encoded transcription factor, Z (BZLF1). We have shown that the Z gene product, which binds to AP-1 sites as a homodimer and has sequence similarity to c-Fos, can efficiently activate the EBV early promoter, BMRF1, in certain cell types (i.e., HeLa cells) but not others (i.e., Jurkat cells). Here we demonstrate that the c-myb proto-oncogene product, which is itself a DNA-binding protein and transcriptional transactivator, can interact synergistically with Z in activating the BMRF1 promoter in Jurkat cells (a T-cell line) or Raji cells (an EBV-positive B-cell), whereas the c-myb gene product by itself has little effect. The simian virus 40 early promoter is also synergistically activated by the Z/c-myb combination. Synergistic transactivation of the BMRF1 promoter by the Z/c-myb combination appears to involve direct binding by the Z protein but not the c-myb protein. A 30-bp sequence in the BMRF1 promoter which contains a Z binding site (a consensus AP-1 site) is sufficient to transfer high-level lymphoid-specific responsiveness to the Z/c-myb combination to a heterologous promoter. That the c-myb oncogene product can interact synergistically with an EBV-encoded member of the leucine zipper protein family suggests c-myb is likely to engage in similar interactions with cellularly encoded transcription factors.

Abstract
The Epstein-Barr virus early antigen diffuse component (EA-D) is essential for Epstein-Barr virus DNA polymerase activity, and its activity is suppressed during latent infection. We investigated the regulation of the promoter (BMRF1) for this early gene by studying its responsiveness in vitro to two immediate-early viral transactivators, BZLF1 (Z) and BRLF1 (R), focusing on the differences in response in lymphoid cells and epithelial cells. In lymphoid cells, Z or R alone produced only small increases in EA-D promoter activity, whereas both transactivators together produced a large stimulatory effect. In epithelial cells, the Z transactivator alone produced maximal stimulation of the EA-D promoter; the effect of R and Z together was no greater than that of Z alone. Deletional analysis and site-directed mutagenesis of the EA-D promoter demonstrated that in epithelial cells the potential AP-1 binding site plays an essential role in Z responsiveness, although sequences further upstream are also important. In lymphoid cells, only the upstream sequences are required for transactivation by the Z/R combination, and the AP-1 site is dispensable. These data suggest that EA-D (BMRF1) promoter regulation by Z and R is cell type specific and appears to involve different mechanisms in each cell type.

Abstract
The Epstein-Barr virus (EBV) immediate-early gene product, BRLF1, transactivates the human immunodeficiency virus type 1 (HIV-1) long terminal repeat. BRLF1-induced transactivation of HIV-1 promoter constructs is accompanied by an increase in plasmid mRNA and is reporter gene independent. Previously, BRLF1 transactivation of EBV promoters has been mapped to regions which function as enhancer elements. Deletional analysis demonstrates that BRLF1 transactivation of the HIV-1 promoter does not require the HIV-1 enhancer. Thus, the EBV BRLF1 gene product may transactivate by at least two different mechanisms, one mechanism involving certain enhancer elements and another mechanism which is enhancer independent.
