Abstract
BACKGROUND Substance use disorders are a leading cause of morbidity and mortality in the United States, with opioid use disorder representing a growing public health concern and economic burden. Veterans within the Veterans Health Administration are impacted by opioid use disorder. SIGNIFICANCE A common medication-assisted treatment is sublingual Suboxone (buprenorphine/naloxone) used in combination with behavior modification therapy. Missed Suboxone doses may lead to withdrawal and potential drug diversion. Sublocade (buprenorphine extended-release) is an alternative once-monthly subcutaneous injection administered by a healthcare provider. The purpose of this quality improvement project was to examine the effects of Sublocade on cravings in veterans with opioid use disorder. METHODS Veterans were considered for Sublocade monthly injections if they were enrolled in the Suboxone program, not taking Suboxone as prescribed, and disenrolled from the Suboxone program more than 2 times. Cravings were measured before and after Sublocade program enrollment. RESULTS Fifteen veterans were enrolled in the Sublocade program over a 12-month timeframe. Most were male (93%) with a median (range) age of 42 (33-62) years. The following were the primary opioids used before enrollment in the substance use disorder program: hydrocodone (47%), oxycodone (20%), and heroin (20%). Sublocade significantly reduced cravings (p = .001). In this small group, cravings were fully eliminated. DISCUSSION Recent studies have shown Sublocade effectively blocks the effects of other opioids and minimizes the risk of medication diversion that occurs with Suboxone. For these reasons, Sublocade is an alternative medication-assisted treatment for veterans with opioid use disorder.

Abstract
BACKGROUND The incidence of anal cancer is substantially higher among persons living with the human immunodeficiency virus (HIV) than in the general population. Similar to cervical cancer, anal cancer is preceded by high-grade squamous intraepithelial lesions (HSILs). Treatment for cervical HSIL reduces progression to cervical cancer; however, data from prospective studies of treatment for anal HSIL to prevent anal cancer are lacking. METHODS We conducted a phase 3 trial at 25 U.S. sites. Persons living with HIV who were 35 years of age or older and who had biopsy-proven anal HSIL were randomly assigned, in a 1:1 ratio, to receive either HSIL treatment or active monitoring without treatment. Treatment included office-based ablative procedures, ablation or excision under anesthesia, or the administration of topical fluorouracil or imiquimod. The primary outcome was progression to anal cancer in a time-to-event analysis. Participants in the treatment group were treated until HSIL was completely resolved. All the participants underwent high-resolution anoscopy at least every 6 months; biopsy was also performed for suspected ongoing HSIL in the treatment group, annually in the active-monitoring group, or any time there was concern for cancer. RESULTS Of 4459 participants who underwent randomization, 4446 (99.7%) were included in the analysis of the time to progression to cancer. With a median follow-up of 25.8 months, 9 cases were diagnosed in the treatment group (173 per 100,000 person-years; 95% confidence interval [CI], 90 to 332) and 21 cases in the active-monitoring group (402 per 100,000 person-years; 95% CI, 262 to 616). The rate of progression to anal cancer was lower in the treatment group than in the active-monitoring group by 57% (95% CI, 6 to 80; P = 0.03 by log-rank test). CONCLUSIONS Among participants with biopsy-proven anal HSIL, the risk of anal cancer was significantly lower with treatment for anal HSIL than with active monitoring.

Abstract
PURPOSE Program evaluation to describe nursing hours per patient day (NHPPD) within the Veterans Health Administration (VHA) and to evaluate Staffing Methodology in the VHA Community Living Centers (CLCs). METHODS Targeted and actual NHPPD were compiled retrospectively for each VHA CLC unit over a one-year timeframe for calendar year 2019. For descriptive analyses, actual NHPPD were averaged across months for each CLC unit. RESULTS The mean for actual hours as a percent of target was 121.6% (95% CI, 118.5 to 124.7%) indicating the units' average hours across 2019 were 21.6% significantly higher than target. The actual NHPPD significantly differed across months (p<0.001) with the 2019 months of January and October having the highest NHPPD. CONCLUSIONS Veteran safety is a VHA priority and appropriate nurse staffing is key to providing care that improves Veteran outcomes. Further exploration is needed on the impact of nurse staffing on Veteran outcomes, safety, and satisfaction.

Abstract
It is well established that persons living with HIV (PLWH) have highly elevated rates of anal HSIL and anal cancer compared with those who are not living with HIV. The 5-year risk of anal cancer following anal HSIL has been reported to be as high as 14.1% among PLWH compared with 3.2% among those who are not living with HIV. To address these concerns, the AIDS Malignancy Consortium completed a large-scale, randomized trial to compare strategies for the prevention of anal cancer among PLWH with anal HSIL. The objective of the study was to determine whether treating anal HSIL was effective in reducing the incidence of anal cancer in PLWH compared with active monitoring. This paper describes the design of the ANal Cancer/HSIL Outcomes Research Study (ANCHOR) with respect to estimating the anal cancer event rate in this high risk population.

Abstract
PURPOSE The purpose of this quality improvement project was to examine the feasibility of rapidly converting a Tai Chi program for older Veterans from face-to-face to virtual classes. METHODS Eighteen Veterans attending our face-to-face Tai Chi course were invited to transition to virtual classes. Feasibility was defined as the ability of program staff and participants to successfully connect and complete the initial and subsequent classes by VA Video Connect (VVC) with little to no technical difficulties, participant ability to participate in the course without safety concerns, and favorable feedback from participants and program staff. RESULTS Nine of 18 Veterans agreed to transition to the virtual program and attended a median (interquartile range) of 11 (4-15) classes; they were younger (62.7 + 11.5 vs. 70.5 + 7.0 years, p < .05) and more likely to have the knowledge and equipment needed to participate (78% vs. 0%, p < .01) than nonparticipants. Tai Chi instructors and participating Veterans reported being able to connect to and complete the classes virtually with only minimal technical problems. No adverse events were reported. Feedback from the instructors and Veterans was positive and included comments on ease of use and enjoyability. CONCLUSION Results suggest that virtual Tai Chi classes via VVC are feasible for some older Veterans.

Abstract
BACKGROUND Apathy, a profound loss of motivation, initiation, and goal directed cognition, is a common comorbidity of Alzheimer's disease (AD). The presence of apathy is associated with rapid progression of AD, long-term impairment, disability, and higher mortality. Pharmacological treatments of apathy are limited. OBJECTIVE The primary objective was to evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) for apathy in AD. METHODS A randomized, double-blind, parallel-arm, sham-controlled pilot study was conducted in subjects with AD and apathy (N = 20). Subjects were randomized to rTMS or sham treatment (5 days/week) for four weeks. Primary outcome, apathy evaluation scale-clinician version (AES-C), and secondary outcome measures, modified-Mini Mental State Examination (3MS), instrumental activities of daily living (IADL), and clinical global impression (CGI), were assessed at baseline and four weeks. Follow-up visits were conducted at 8 and 12 weeks to test the durability of effects of intervention. RESULTS Mean age was 77.3 (±7.2) years, 80% were Caucasians and 10% were females. After adjusting for baseline, there was a significantly greater improvement in the AES-C with rTMS compared to sham treatment (-10.1 (-15.9 to -4.3); t (16) = -3.69; p = 0.002) at 4 weeks. There was also significantly greater improvement in 3MS (6.9 (1.7 to 12.0); t (15) = 2.85; p = 0.012), IADL (3.4 (1.0 to 5.9); χ21 = 7.72; p = 0.006), CGI-S (1.4 (0.5 to 2.3), t (16) = 3.29; p = 0.005), and CGI-I (-2.56 (-3.5 to -1.6), t (17) = -5.72; p < 0.001) for rTMS compared to the sham at 4 weeks. The effects of rTMS were durable at 12 weeks. CONCLUSION rTMS may be safely used in subjects with AD and may improve apathy, function, and some aspects of cognition.

Abstract
BACKGROUND We aimed to determine if treatment of male sexual partners of women with recurrent bacterial vaginosis (BV) with oral metronidazole 2×/day for 7 days (ie, multidose metronidazole) significantly decreased BV recurrence rates in the female. METHODS This was a multicenter, 2-arm, double-blind, placebo-controlled study. Women with recurrent BV and current diagnosis of BV by Amsel and Nugent were enrolled. Multidose metronidazole for 7 days was dispensed to women. Male partners were randomized to placebo versus multidose metronidazole for 7 days and asked to refrain from unprotected sex for 14 days. Female follow-up visits were conducted at day 21 and 8 and 16 weeks. Male follow-up visits occurred at days 14-21. BV cure was defined as 0-2 Amsel criteria and Nugent score 0-6 in the female partner with the primary endpoint at 16 weeks. RESULTS 214 couples were enrolled. In the intent-to-treat population, there was no significant difference between treatment arms for the primary outcome. BV treatment failure occurred in 81% and 80% of women in the metronidazole and placebo arms through the third follow-up visit, respectively (P > .999). However, women whose male partners adhered to study medication were less likely to fail treatment (adjusted relative risk, .85; 95% CI, .73-.99; P = .035). This finding persisted in post hoc comparisons in the metronidazole arm. CONCLUSIONS Overall, this study did not find that male partner treatment with multidose metronidazole significantly reduces BV recurrence in female partners, although women whose partners adhered to multidose metronidazole were less likely to fail treatment.

Abstract
RATIONALE AND OBJECTIVES The purpose of this study is to analyze the significance of specific factors in choosing radiology as a specialty compared to switching to/from a different specialty as reported in the Graduation Questionnaire (GQ) and Matriculating Student Questionnaire (MSQ) data provided by Association of American Medical Colleges. METHOD AND MATERIALS The study cohort included students who completed both the MSQ and GQ questionnaires in the span of 3-5 years. The cohort was divided into three groups-"Committed" (students who chose radiology in both the first and final year of medical school), "Switched Away" (students who chose radiology on the MSQ but later switched to a different specialty, and "Switched-To" (students who chose radiology on GQ after initially selecting an alternate specialty on the MSQ). RESULTS Of 1965 students who chose radiology between the years 2013 and 2016, 281 were Committed, 625 Switched-Away, and 1059 Switched-To. There were significant differences among the groups for salary, length of residency, and work-life balance factors. In the Switched-Away group, more students were influenced by length of residency (18% vs. 5%, p < 0.001) and fewer were influenced by salary (21% vs. 30%, p=0.004) or work-life balance (54% vs. 66%, p = 0.001) when compared to the Committed group. The Switched-To group did not significantly differ from the Committed group (all p > 0.05) for length of residency (6% vs. 5%), salary (30% vs. 30%) and work-life balance (69% vs. 66%). CONCLUSION The data provide insight into factors that influence medical students to initially commit to, switch away from, and switch to radiology during medical school. Understanding these dynamics can inform mentors to guide medical students who are interested in a radiology career.

Abstract
BACKGROUND Women living with HIV (WLWH) experience high rates of anal cancer. Screening using anal cytology, high-resolution anoscopy (HRA) with biopsies, can histologically diagnose anal cancer precursors called high-grade squamous intraepithelial lesions (HSIL). The low specificity of screening using anal cytology results in HRA referral for many WLWH without HSIL. Screening using high-risk human papillomavirus (HR-HPV) may improve specificity. METHODS Two hundred seven WLWH (63% non-Hispanic black) were screened for anal histologic HSIL (hHSIL) using cytology, HRA-guided biopsies, and Xpert HPV. Xpert performance for predicting anal hHSIL was compared with that of cytology. Usng Xpert 5 HPV genotypic results and accompanying cycle thresholds, receiver operator characteristic curve and recursive partitioning analyses were used to create predictive models for hHSIL. RESULTS The performance of Xpert to predict hHSIL was not different from that of cytology with a sensitivity (Sn) of 89% and specificity (Sp) of 49%. Interpretation of Xpert was modified using genotypic results and receiver operator characteristic curve analysis, which produced a screen with an Sn and Sp of 75% and 84% for hHSIL, respectively. Another reinterpretation of Xpert was created using recursive partitioning and cycle thresholds, which predicted hHSIL with an Sn and Sp of 75% and 86%, respectively. The detection of HPV-16 was highly predictive of hHSIL in all analyses. These modified screening tests would reduce HRA referral in this population by almost half compared with anal cytology. CONCLUSIONS Xpert HPV is an alternative to anal cytology to screen for anal HSIL and can be optimized to reduce the number of unnecessary HRAs performed in WLWH.

Abstract
Background Men who have sex with men (MSM) are at high risk for human papillomavirus (HPV)–related anal cancer. Little is known about the prevalence of low-grade squamous intraepithelial lesions (LSILs) and the anal cancer precursor, high-grade squamous intraepithelial lesions (HSILs), among young MSM with HIV (MSMLWH). HPV vaccination is recommended in this group, but its safety, immunogenicity, and protection against vaccine-type HPV infection and associated LSILs/HSILs have not been studied. Methods Two hundred and sixty MSMLWH aged 18–26 years were screened at 17 US sites for a clinical trial of the quadrivalent (HPV6,11,16,18) HPV (qHPV) vaccine. Those without HSILs were vaccinated at 0, 2, and 6 months. Cytology, high-resolution anoscopy with biopsies of lesions, serology, and HPV testing of the mouth/penis/scrotum/anus/perianus were performed at screening/month 0 and months 7, 12, and 24. Results Among 260 MSMLWH screened, the most common reason for exclusion was detection of HSILs in 88/260 (34%). 144 MSMLWH were enrolled. 47% of enrollees were previously exposed to HPV16. No incident qHPV type–associated anal LSILs/HSILs were detected among men naive to that type, compared with 11.1, 2.2, 4.5, and 2.8 cases/100 person-years for HPV6,11,16,18–associated LSILs/HSILs, respectively, among those previously exposed to that type. qHPV was immunogenic and safe with no vaccine-associated serious adverse events. Conclusions 18–26-year-old MSMLWH naive to qHPV vaccine types were protected against incident qHPV type–associated LSILs/HSILs. Given their high prevalence of HSILs, there is an urgent need to vaccinate young MSMLWH before exposure to vaccine HPV types, before initiating sexual activity, and to perform catch-up vaccination.

Abstract
BACKGROUND Women living with human immunodeficiency virus (WLHIV) have disproportionately high rates of squamous cell carcinoma of the anus compared with the general population of women. Anal high-grade squamous intraepithelial lesions (HSILs) precede anal cancer, and accurate studies of HSIL prevalence among WLHIV in the United States are lacking. METHODS The AIDS Malignancy Consortium 084 study was a multicenter national trial to evaluate the prevalence of and risk factors for anal HSIL in a US cohort. Eligible participants were WLHIV aged ≥18 years with no history of anal HSIL. Study participants had an examination including collection of cervical/vaginal and anal specimens, followed by high-resolution anoscopy with biopsy. RESULTS We enrolled 256 women with evaluable anal pathology. The mean age was 49.4 years, 64% women were non-Hispanic black, 67% were former or current smokers, and 56% reported ever having anal sex with a man. The median CD4 T-cell count was 664 cells/μL. The prevalence of anal histologic HSIL (hHSIL) was 27% (95% confidence interval [CI], 22%-33%). There was a strong concordance (240/254) between local and consensus pathologists for hHSIL vs less than hHSIL (κ = 0.86 [95% CI, .79-.93]). Current CD4 count of ≤200 cells/μL was the strongest predictor of consensus anal hHSIL diagnosis (adjusted odds ratio [aOR], 10.34 [95% CI, 3.47-30.87]). History of anoreceptive intercourse was also associated with hHSIL (aOR, 2.44 [95% CI, 1.22-4.76]). CONCLUSIONS The prevalence of anal hHSIL in WLHIV in the United States was 27% in this study where all participants received high-resolution anoscopy and biopsy.

Abstract
PURPOSE To evaluate the effectiveness of an evidence-based 12-week Tai Chi course designed to improve balance and physical function in a population of older veterans. METHODS Community dwelling veterans of all ages with gait and balance problems were invited to participate in the Tai Chi program. Participants completed the Berg Balance Scale (BBS), the Timed Up and Go (TUG) test, and the Falls Efficacy Scale-International (FES-I) at baseline and again at the end of the program. Descriptive statistics were used to summarize study participants' characteristics. The change from baseline to the end of the 12-week program was calculated for each of the three primary outcome variables (BBS, TUG, FES-I). RESULTS Twenty-two veterans, aged 58 years and above, with perceived gait and/or balance issues were enrolled in the program with completion by 11 veterans. Veterans who completed their final assessments showed the BBS, improved significantly (p = 0.004) from baseline to the 12-week assessment. The TUG scores improved by a median of 1.3 s (p = 0.022). There was not a significant change in the FES-I. CONCLUSIONS Preliminary findings provide evidence of the effectiveness of a 12-week Tai Chi program to improve functional outcomes for older veterans with mild to moderate gait and balance problems.

Abstract
Background Many general practitioners consider dementia care beyond their clinical domain and feel that dementia assessment and treatment should be addressed by specialists, such as geriatricians, geriatric psychiatrists, or neurologists. An urgent need exists to educate all medical trainees in dementia care, regardless of their specialization interests. Observations We developed a multicomponent, experiential, brief curriculum using team-based learning to expose senior medical students who rotated through the US Department of Veterans Affairs Memory Disorders Clinic at the Central Arkansas Veterans Healthcare System in Little Rock to an interdisciplinary assessment of dementia. The curriculum included didactics, clinical experience, and team-based learning. In pre- and postevaluation, students rated their perception of the role of interdisciplinary team members in assessing and managing dementia, their personal abilities to assess cognition, behavioral problems, caregiver burden, and their perception of the impact of behavioral problems on dementia care. Conclusions Dementia knowledge gaps were prevalent in this cohort of senior medical students. Providing interdisciplinary geriatric educational experience improved students perception of their ability to assess for dementia and their recognition of the roles of interdisciplinary team members. Plans are in place to continue and expand the program to other complex geriatric syndromes.

Abstract
BACKGROUND Anal high-grade squamous intraepithelial lesions (HSILs) ablation may reduce the incidence of invasive cancer, but few data exist on treatment efficacy and natural regression without treatment. METHODS An open-label, randomized, multisite clinical trial of human immunodeficiency virus (HIV)-infected adults aged ≥27 years with 1-3 biopsy-proven anal HSILs (index HSILs) without prior history of HSIL treatment with infrared coagulation (IRC). Participants were randomized 1:1 to HSIL ablation with IRC (treatment) or no treatment (active monitoring [AM]). Participants were followed every 3 months with high-resolution anoscopy. Treatment participants underwent anal biopsies of suspected new or recurrent HSILs. The AM participants underwent biopsies only at month 12. The primary end point was complete clearance of index HSIL at month 12. RESULTS We randomized 120 participants. Complete index HSIL clearance occurred more frequently in the treatment group than in the AM (62% vs 30%; risk difference, 32%; 95% confidence interval [CI], 13%-48%; P < .001). Complete or partial clearance (clearance of ≥1 index HSIL) occurred more commonly in the treatment group (82% vs 47%; risk difference, 35%; 95% CI, 16%-50%; P < .001). Having a single index lesion, compared with having 2-3 lesions, was significantly associated with complete clearance (relative risk, 1.96; 95% CI, 1.22-3.10). The most common adverse events related to treatment were mild or moderate anal pain and bleeding. No serious adverse events were deemed related to treatment or study participation. CONCLUSION IRC ablation of anal HSILs results in more clearance of HSILs than observation alone.

Abstract
PURPOSE The purpose of this nurse-led project was to increase the number of interprofessional Tai Chi instructors for veterans through a 5-week (32 hours) training of trainers (ToT) course led by a Tai Chi master trainer. METHODS This project was designed to evaluate the effectiveness of using the ToT model to increase the availability of Tai Chi to veterans. To understand how well the ToT course met learners' needs, a two-phase course evaluation was conducted. RESULTS Fifteen interprofessional employees enrolled in and completed the course. Most learners were white (67%) females (67%) with a median age of 50 years. All agreed that the training provided the skills, materials, and confidence to lead Tai Chi classes. Most (93%) indicated experiencing positive health benefits from the training and none experienced any negative effects. The 3-month follow-up evaluation indicated that 10 (67%) were teaching veterans in individual or group classes with two others assisting. Twelve instructors taught more than 150 veterans. CONCLUSIONS Overall, learners evaluated this ToT course positively and indicated their needs were met and felt prepared to teach Tai Chi despite being inexperienced. The course was a success with 80% of new instructors teaching or coteaching Tai Chi to veterans.

Abstract
Reduction of cardiovascular disease risk in undeserved populations, such as older women, is a top priority of the U.S. Our innovative trial tested a new approach to PA promotion for older women—motivational interviewing (MI), shifting the paradigm from structured exercise to self-selected activities. We present data comparing stage of change (SOC), self-efficacy for exercise (SEE), and well-being: 8 dimensions (physical, social, role limitations, emotional, general mental health, vitality, health perceptions and pain) and associations with physical activity outcomes in the Lifestyle Physical Activity for Women (LPAW) clinical trial. Methods: 106 women, > 60 years old, who did not engage in regular PA, and were not frail, participated in a clinical trial of a tailored MI intervention to increase PA. We report baseline, 3 and 6 month repeated measures and PA associations with SOC, SEE, and well-being (SF36). Results: Of 106 women, 36% were Black and 63% White, with a mean age of 69. Significant improvement in SOC in both arms noted but the proportion in action/maintenance was significantly higher in the PA arm at 3 mos (78% vs. 55%, P=0.045) and 6 mos (79% vs. 50%, P= 0.019). A decrease in SEE for control (p=.001), but not for PA arm (p=.45); at 6 months, The PA arm had greater SEE compared to control. There were significant arm difference for physical component scores of SF36 (p=.02), but not for mental scores. Associations with PA will be tabulated. Conclusions: Preliminary results support the PA intervention, more data to be presented.

Abstract
PURPOSE AIDS-related Kaposi sarcoma is often incompletely controlled, requiring serial therapies. Kaposi sarcoma herpesvirus (KSHV) induces transformation of endothelial cells, where it resides in a predominately latent state. We hypothesized proteasome inhibition would have direct antitumor activity, induce lytic activation of KSHV, and inhibit HIV infectivity, improving control of both Kaposi sarcoma and HIV. The primary objective was determining the MTD of bortezomib in AIDS-Kaposi sarcoma. Secondary objectives included estimating the impact of bortezomib on Kaposi sarcoma response, KSHV plasma DNA copy number (PDCN), and HIV viral loads (VL). PATIENTS AND METHODS A 3+3 dose escalation design was employed evaluating four dose levels of bortezomib (0.75, 1, 1.2, or 1.6 mg/m2) administered intravenously on days 1, 8, and 15 of 28-day cycles in patients with relapsed/refractory (r/r) AIDS-Kaposi sarcoma taking antiretroviral therapy. RESULTS Seventeen patients enrolled. No dose-limiting toxicities occurred and the MTD was not reached. The most common adverse events included diarrhea, fatigue and nausea. Among 15 evaluable patients, partial response (PR) occurred in nine (60%), with a PR rate of 83% in the 1.6 mg/m2 cohort; the remainder had stable disease (SD). Median time to response was 2.1 months. Median change in KSHV PDCN was significantly different between those with PR versus SD. During cycle 1, seven of 11 evaluable patients had decreases in HIV VL. CONCLUSIONS Bortezomib is well-tolerated and active in AIDS-Kaposi sarcoma. The 60% PR rate is notable given the dose-finding nature of the study in a r/r population. Changes in KSHV PDCN and HIV VL trended as hypothesized.

Abstract
OBJECTIVE The epidemiology of bacterial vaginosis (BV) favours sexual transmission of BV-associated bacteria. We examined incubation period and risk factors for incident BV (iBV) in a prospective study of women who have sex with women (WSW). METHODS Using daily self-collected vaginal swabs, WSW with normal vaginal microbiota (no Amsel criteria and a Nugent score of 0-3) were followed for 90 days or until iBV (Nugent score 7-10 on at least 2-3 consecutive days). Daily diaries of sexual activity and menses were completed. Time to iBV was estimated. Accounting for differing lengths of follow-up and age, rates of sexual activities (per 100 person-days (pd)) were compared according to iBV status. The relationship between menses and iBV was also investigated. RESULTS Of the 36 WSW, the mean age was 30 years (SD 8) and 92% were African American. The probability of iBV at 30 and 60 days was 20% (SD 7%) and 36% (SD 8%), respectively; 14 (39%) developed iBV by 90 days. In WSW with iBV versus those without iBV, the relative rate of any sexual activity prior to iBV was 40% higher (20.4 vs 14.6 per 100 pd; p=0.010), sex with a woman was 38% higher (14.3 vs 10.3 per 100 pd; p=0.038), digital-vaginal sex was 57% higher (14.3 vs 9.1 per 100 pd; p=0.005) and digital-anal sex was 5.6 times higher (2.9 vs 0.5 per 100 pd; p<0.001). iBV was more likely for those WSW with menses in the prior 2 days as compared with those without recent menses (HR 3.4; p=0.029). Sexual activity occurred in 93% WSW at a median of 4 days (95% CI 2 to 6) prior to iBV. CONCLUSION iBV was common and associated with sexual activity in this cohort of predominantly African American WSW. An incubation period of 4 days is consistent with other bacterial STIs.

Abstract
PURPOSE To determine the feasibility, safety, and tolerability of concomitant chemoradiotherapy administered at standard doses in HIV-infected women with locally-advanced cervical cancer (LACC) receiving antiretroviral therapy (ART). PATIENTS AND METHODS Eligible participants had HIV infection and untreated, histologically-confirmed, invasive carcinoma of the uterine cervix, FIGO stages IB2, IIA (if tumor >4 cm), IIB, IIIA, IIIB, or IVA and met standard eligibility criteria. Subjects were prescribed 41.4-45 Gy external beam radiation therapy followed by high dose rate brachytherapy concomitant with up to six weekly doses of cisplatin 40 mg/m2 and were followed for 12 months. RESULTS Sixty-four women were screened at two sites in sub-Saharan Africa, of whom 40 eligible participants were enrolled, for a screening ratio of 1.60. Of the 38 eligible participants who initiated study treatment, 31 (82%) completed treatment. By the 12-month follow-up visit, 7 women had died of disease and 29 of 31 (94%) returned for follow-up. One-year progression-free survival was 76.3% (95% CI, 59.4-86.9%), and did not significantly differ according to stage at entry (p = 0.581). Participant-reported adherence to ART was high; by 12 months, 93% of participants had an undetectable viral load. The most common grade 3 or 4 adverse event was decreased lymphocyte count that affected all treated participants. Non-hematologic serious adverse events were similar to those observed in women with LACC without HIV infection. CONCLUSIONS The majority of HIV-infected women with LACC can complete concomitant chemoradiotherapy with the same cisplatin dose used in HIV-uninfected women with comparable tolerability and high ART adherence while on treatment.

Abstract
The relative potency of one agent to another is commonly represented by the ratio of two quantal response parameters; for example, the LD50 of animals receiving a treatment to the LD50 of control animals, where LD50 is the dose of toxin that is lethal to 50% of animals. Though others have considered interval estimators of LD50, here, we extend Bayesian, bootstrap, likelihood ratio, Fieller's and Wald's methods to estimate intervals for relative potency in a parallel-line assay context. In addition to comparing their coverage probabilities, we also consider their power in two types of dose designs: one assigning treatment and control the same doses vs. one choosing doses for treatment and control to achieve same lethality targets. We explore these methods in realistic contexts of relative potency of radiation countermeasures. For larger experiments (e.g., ≥100 animals), the methods return similar results regardless of the interval estimation method or experiment design. For smaller experiments (e.g., < 60 animals), Wald's method stands out among the others, producing intervals that hold closely to nominal levels and providing more power than the other methods in statistically efficient designs. Using this simple statistical method within a statistically efficient design, researchers can reduce animal numbers.

Abstract
Background: Adaptive immune responses that mediate protection against Chlamydia trachomatis (CT) remain poorly defined in humans. Animal chlamydia models have demonstrated that CD4+ Th1 cytokine responses mediate protective immunity against reinfection. To better understand protective immunity to CT in humans, we investigated whether select CT-specific CD4+ Th1 and CD8+ T cell cytokine responses were associated with protection against CT reinfection in women. Methods: Peripheral blood mononuclear cells were collected from 135 CT-infected women at treatment and follow-up visits and stimulated with CT antigens. CD4+ and CD8+ T-cells expressing IFN-γ, TNF-α, and/or IL-2 were assessed using intracellular cytokine staining and cytokine responses were compared between visits and between women with vs. without CT reinfection at follow-up. Results: A CD4+TNF-α response was detected in the majority (77%) of study participants at the treatment visit, but a lower proportion had this response at follow-up (62%). CD4+ IFN-γ and CD4+ IL-2 responses occurred less frequently at the treatment visit (32 and 18%, respectively), but increased at follow-up (51 and 41%, respectively). CD8+ IFN-γ and CD8+ TNF-α responses were detected more often at follow-up (59% for both responses) compared to the treatment visit (30% for both responses). At follow-up, a CD4+IFN-γ response was detected more often in women without vs. with reinfection (60 vs. 33%, P = 0.005). Conclusions: Our findings suggest that a CT-specific CD4+ IFN-γ response is associated with protective immunity against CT reinfection and is thus an important component of adaptive immunity to CT in women.

Abstract
BACKGROUND/OBJECTIVE Balance problems are common in older adults with Alzheimer's disease (AD). The objective was to study the effects of a Wii-Fit interactive video-game-led physical exercise program to a walking program on measures of balance in older adults with mild AD. METHODS A prospective randomized controlled parallel-group trial (Wii-Fit versus walking) was conducted in thirty community-dwelling older adults (73±6.2 years) with mild AD. Home-based exercises were performed under caregiver supervision for 8 weeks. Primary (Berg Balance Scale, BBS) and secondary outcomes (fear of falls and quality of life) were measured at baseline, 8 weeks (end of intervention), and 16 weeks (8-weeks post-intervention). RESULTS At 8 weeks, there was a significantly greater improvement (average inter-group difference [95% CI]) in the Wii-Fit group compared to the walking group in BBS (4.8 [3.3-6.2], p < 0.001), after adjusting for baseline. This improvement was sustained at 16 weeks (3.5 [2.0-5.0], p < 0.001). Analyses of the secondary outcome measures indicated that there was a significantly greater improvement in the Wii-Fit group compared to walking group in Activity-specific Balance Confidence scale (6.5 [3.6-9.4], p < 0.001) and Falls Efficacy Scale (-4.8 [-7.6 to -2.0], p = 0.002) at 8 weeks. However, this effect was not sustained at 16 weeks. Quality of life improved in both groups at 8 weeks; however, there were no inter-group differences (p = 0.445). CONCLUSION Home-based, caregiver-supervised Wii-Fit exercises improve balance and may reduce fear of falling in community-dwelling older adults with mild AD.

Abstract
Apathy is a common and disabling behavioral concomitant of many neurodegenerative conditions. The presence of apathy with Mild Cognitive Impairment (MCI) is linked with heightened rates of conversion to Alzheimer's disease. Improving apathy may slow the neurodegenerative process. The objective was to establish the efficacy of repetitive transcranial magnetic stimulation (rTMS) in improving apathy in older adults with MCI. An 8-week, double-blind, randomized, sham-controlled cross-over study was conducted in nine subjects (66 ± 9 years) with apathy and MCI. Subjects were randomized to rTMS or sham treatment (5 days/week) for 2 weeks following which they underwent a 4-week treatment-free period. Subjects then crossed-over to receive the other treatment for 2 weeks. The primary (apathy (AES-C)) and secondary (cognition (3MS & MMSE), executive function (TMT-A & TMT-B), and clinical global impression (CGI)) outcomes were assessed at baseline, 2, 6, and 8 weeks. After adjusting for baseline, there was a significantly greater improvement in the AES-C with rTMS compared to sham treatment at 2 weeks. There was significantly greater improvement in 3MS, MMSE, TMT-A, and CGI-I with rTMS compared to the sham treatment. This study establishes that rTMS is efficacious in improving apathy in subjects with MCI.

Abstract
OBJECTIVE Apathy is a common behavioral problem in Alzheimer's disease. Apathy has profound consequences, such as functional impairment, higher service utilization, higher caregiver burden, and increased mortality. The authors' objective was to study the effects of methylphenidate on apathy in Alzheimer's disease. METHOD A 12-week, prospective, double-blind, randomized, placebo-controlled trial (methylphenidate versus placebo) was conducted in community-dwelling veterans (N=60) with mild Alzheimer's disease. The primary outcome for apathy (Apathy Evaluation Scale-Clinician) and secondary outcomes for cognition (Mini-Mental State Examination, Modified Mini-Mental State Examination), functional status (activities of daily living, instrumental activities of daily living), improvement and severity (Clinical Global Impressions Scale [CGI]), caregiver burden (Zarit Burden Scale), and depression (Cornell Scale for Depression in Dementia) were measured at baseline and at 4, 8, and 12 weeks. RESULTS Participants were all men (77 years old, SD=8). After adjusting for baseline, the methylphenidate group had significantly greater improvement in apathy than the placebo group at 4 weeks, 8 weeks, and 12 weeks. At 12 weeks, there was also greater improvement in cognition, functional status, caregiver burden, CGI scores, and depression in the methylphenidate group compared with the placebo group. CONCLUSIONS Methylphenidate improved apathy in a group of community-dwelling veterans with mild Alzheimer's disease. Methylphenidate also improved cognition, functional status, caregiver burden, CGI scores, and depression.

Abstract
BACKGROUND/OBJECTIVES An elevated blood urea nitrogen (BUN) in known to be an important prognostic indicator in patients with end-stage heart or kidney disease or certain other life-threatening illnesses. However, it is less certain as to whether an elevated BUN is an independent predictor of long-term mortality risk in less seriously ill patients. To address this issue, we examined the relationship between BUN and long-term mortality after adjusting for potential confounders and other indicators of health status/disease severity, in a select population of older medically stable Veterans. DESIGN Long-term prospective cohort study. SETTING Outpatient follow-up of patients discharged from a recuperative care and rehabilitation unit (RCRU) of a Department of Veterans Affairs Community Living Center. PARTICIPANTS 383 older Veterans (mean age = 78.6±7.6 years, 98% male, and 87% white) discharged alive and in stable medical condition. MEASUREMENTS At discharge, each subject completed a comprehensive assessment and was then monitored as an outpatient for up to 9.3 years. Associations between blood urea nitrogen at RCRU discharge and mortality were identified utilizing Cox proportional hazards (PH) regression analyses adjusting for conditions known to confound this relationship. RESULTS Within the follow-up period, 255 subjects (67%) died. In the unadjusted Cox PH model, a BUN ≥ 30 mg/dL was associated with a nearly 2-fold increased risk of mortality (hazard ratio 1.90, 95%CI 1.41 - 2.56). The association between BUN and long-term mortality remained highly significant after adjusting for potential confounders (hazard ratio 1.78, 95%CI 1.29 - 2.44). CONCLUSION Our findings support BUN levels as an independent predictor of long-term mortality in older, medically stable Veterans. An elevated BUN may be reflective of global health status rather than solely an indicator of the severity of acute illness or unstable chronic disease.

Abstract
High response rates to surveys of physicians are difficult to achieve. One possible strategy to improve physicians’ survey participation is to offer the option of receiving and returning the survey by fax. This study describes the success of the option of fax communication in a survey of general practitioners, family physicians, and pediatricians in Arkansas with regard to pediatric asthma. Eligible physicians were given the choice of receiving the survey by telephone, mail, or fax. In this observational study, physicians’ preferences, response rates, and biases for surveys administered by fax were compared with mail and telephone surveys. The overall survey response rate was 59%. For the 96 physicians completing an eligibility screener survey, the largest percentage requested to be surveyed by fax (47%) rather than by telephone (28%) or mail (25%). Faxing may be one strategy to add to the arsenal of tools to increase response rates in surveying physicians.

Abstract
BACKGROUND Urogenital Chlamydia trachomatis infection remains prevalent and causes substantial reproductive morbidity. Recent studies have raised concern about the efficacy of azithromycin for the treatment of chlamydia infection. METHODS We conducted a randomized trial comparing oral azithromycin with doxycycline for the treatment of urogenital chlamydia infection among adolescents in youth correctional facilities, to evaluate the noninferiority of azithromycin (1 g in one dose) to doxycycline (100 mg twice daily for 7 days). The treatment was directly observed. The primary end point was treatment failure at 28 days after treatment initiation, with treatment failure determined on the basis of nucleic acid amplification testing, sexual history, and outer membrane protein A (OmpA) genotyping of C. trachomatis strains. RESULTS Among the 567 participants enrolled, 284 were randomly assigned to receive azithromycin, and 283 were randomly assigned to receive doxycycline. A total of 155 participants in each treatment group (65% male) made up the per-protocol population. There were no treatment failures in the doxycycline group. In the azithromycin group, treatment failure occurred in 5 participants (3.2%; 95% confidence interval, 0.4 to 7.4%). The observed difference in failure rates between the treatment groups was 3.2 percentage points, with an upper boundary of the 90% confidence interval of 5.9 percentage points, which exceeded the prespecified absolute 5-percentage-point cutoff for establishing the noninferiority of azithromycin. CONCLUSIONS In the context of a closed population receiving directly observed treatment for urogenital chlamydia infection, the efficacy of azithromycin was 97%, and the efficacy of doxycycline was 100%. The noninferiority of azithromycin was not established in this setting. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT00980148.).

Abstract
PURPOSE To establish effective aorta diameter standards at multiple levels of the thoracic aorta, abdominal aorta, and common iliac arteries by using computed tomographic (CT) data in healthy children (infants, children, adolescents) through young adults (hereafter referred to collectively as "children") of a wide range of sizes so that z scores may be calculated. MATERIALS AND METHODS This retrospective study was approved by the institutional review board. The effective diameter, the average of aortic anteroposterior and lateral diameters, was independently measured at multiple levels of the aorta and common iliac arteries by two radiologists using 1-mm-collimation double-oblique reconstructions. Ordinary least squares regression methods were used to investigate models with various functional forms that related effective diameters at each level to patient body surface area (BSA) and sex. The best model was selected by using R(2), and formulas for deriving the expected diameter and estimates of the mean squared error (MSE) were generated. RESULTS Results from 88 thoracic and 110 abdominal contrast material-enhanced CT examinations were analyzed in children without known cardiovascular disease who ranged in age from 0 to 20 years (mean, 9.9 years; standard deviation, 5.7), with BSA ranging from 0.19 to 2.52 m(2). Excellent interrater reliability was present (correlation coefficients ranged from 0.95 to 0.98). The best model was a polynomial regression model of the natural log transformation of the effective diameter that included linear, quadratic, and cubic BSA terms and a sex main effect as independent variables. The z scores were calculated by using the observed and expected effective diameters and the MSE. CONCLUSION The range of normal effective diameters of the aorta at multiple levels and the common iliac arteries was determined for children of different sizes and both sexes. Measurements outside of the normal ranges are consistent with aneurysm or hypoplasia.

Abstract
RATIONALE AND OBJECTIVES Residency recruitment is a critical and expensive process. A program's Web site may improve recruitment, but little is known about how applicants use program sites or what constitutes optimal content. The importance of an interview day and interactions with a program's residents has been described, but candidate preferences for various activities and schedules have not been widely reported. We investigated contemporary use and perceived utility of information provided on radiology program Web sites, as well as preferences for the interview day experience. MATERIALS AND METHODS Using an anonymous cross-sectional survey, we studied 111 candidates who were interviewed between November 1, 2012 and January 19, 2013 for a diagnostic radiology residency position at our institution. Participation in this institutional review board-approved study was entirely voluntary, and no identifying information was collected. Responses were sealed and not analyzed until after the match. RESULTS A total of 70 candidates returned a completed survey (63% response rate). Optimal content considered necessary for a "complete" Web site was identified. The most important factor in deciding where to apply was geographical connection to a program. "AuntMinnie" was the most popular source of program information on social media. Candidates overwhelmingly preferred one-on-one faculty interviews but had no preference between a Saturday and weekday schedule. The ideal interview experience should include a "meet and greet" with residents off campus and a personal interview with the program director. The overall "feel" or "personality" of the program was critical to a candidate's rank order decision. CONCLUSIONS Our findings offer insight into what factors make programs appealing to radiology applicants. This information will be useful to medical educators engaged in career counseling and recruitment.

Abstract
AIM: To report our preliminary experience with a new generation aspiration catheter in the treatment of symptomatic pulmonary embolism (PE).
METHODS: A retrospective database search for pulmonary artery embolectomy since introduction of the Pronto .035” and XL extraction catheter (Vascular Solutions, Minneapolis, MN) at our institution in 10/2009 was performed. Ten consecutive patients were identified in which the Pronto .035” or XL catheter was used between 01/2010 and 03/2013. All patients were referred for catheter based embolectomy due to contraindications to systemic lysis, or for being in such a critical clinical condition that immediate percutaneous treatment deemed warranted. The computed tomography (CT) right to left heart ratio as predictor for the severity of the PE was retrospectively evaluated on standard axial views. The difference between pre- and post-procedure pulmonary pressure measures was taken to assess the procedural effect.
RESULTS: Extensive PE was confirmed angiographically in all patients. Measured right- to left ventricle (RV/LV) ratios were elevated beyond one in seven of the eight available CTs. Acute procedural success defined as clinical removal of visible thrombus and improvement in mean pulmonary artery pressure was seen in all recorded patients (n = 8), the mean pulmonary pressures declined from a median (range) of 35.5 (19-46) to 23 (10-37, P = 0.008) mmHg. Neither death nor other complications occurred intra- or immediately periprocedural, yet short term mortality within 30 d was found in 6 out of 9 patients, one patient was lost in follow up. The cause of death within 30 d in the 6 patients was identified as: Circulatory failure in direct connection with the PE (n = 2), stroke, sepsis, or succumbing to malignancy in a hospice setting (n = 2).
CONCLUSION: Success in thrombus removal with improved pulmonary hypertension and systemic hypotension suggests this aspiration technique to be effective. Aspiration catheters should be part of further trials.

Abstract
The dose of a substance that causes death in P% of a population is called an LDP, where LD stands for lethal dose. In radiation research, a common LDP of interest is the radiation dose that kills 50% of the population by a specified time, i.e., lethal dose 50 or LD50. When comparing LD50 between two populations, relative potency is the parameter of interest. In radiation research, this is commonly known as the dose reduction factor (DRF). Unfortunately, statistical inference on dose reduction factor is seldom reported. We illustrate how to calculate confidence intervals for dose reduction factor, which may then be used for statistical inference. Further, most dose reduction factor experiments use hundreds, rather than tens of animals. Through better dosing strategies and the use of a recently available sample size formula, we also show how animal numbers may be reduced while maintaining high statistical power. The illustrations center on realistic examples comparing LD50 values between a radiation countermeasure group and a radiation-only control. We also provide easy-to-use spreadsheets for sample size calculations and confidence interval calculations, as well as SAS® and R code for the latter.

Abstract
The natural history of chlamydia is variable and may include persisting asymptomatic infection, complications, or spontaneous resolution before treatment. Reinfection is common. We evaluated whether spontaneous resolution was associated with decreased reinfection in women returning for treatment of a positive chlamydia screening test. At enrollment, participants were tested for chlamydia, treated with azithromycin, and scheduled for a 6-month follow-up visit for repeat testing. Two hundred participants returned 1 to 12 months after treatment. Spontaneous resolution at enrollment was demonstrated in 44 (22.0%). Reinfection at follow-up occurred in 33 (16.5%), being more frequent in those with persisting infection at enrollment versus spontaneous resolution (31 of 156 [19.9%] vs 2 of 44 [4.5%]; P = .016). Adjusting for age, the odds of reinfection was 4 times higher for participants with persisting infection at enrollment (odds ratio 4.0, 95% confidence interval, 1.1-25.6; P = .034). Chlamydia treatment may attenuate protective immunity in some patients.

Abstract
PURPOSE High-grade anal intraepithelial neoplasia (HGAIN) is the precursor lesion to invasive anal cancer. Human papillomavirus (HPV) vaccination holds great promise for preventing anal cancer. METHODS We examined 235 HIV-1-infected men screening for participation in a multisite clinical trial of a quadrivalent HPV vaccine. All participants had anal swabs obtained for HPV testing and cytology and high-resolution anoscopy with biopsies of visible lesions to assess for HGAIN. RESULTS HPV types 16 and 18 were detected in 23% and 10%, respectively; abnormal anal cytology was found in 56% and HGAIN in 30%. HGAIN prevalence was significantly higher in those with HPV16 detection compared to those without (38% vs 17%; P = .01). Use of antiretroviral therapy and nadir and current CD4+ cell count were not associated with abnormal anal cytology or HGAIN. CONCLUSION HGAIN is highly prevalent in HIV-infected men. Further studies are needed on treatment and prevention of HGAIN.

Abstract
Background To estimate a classifier’s error in predicting future observations, bootstrap methods have been proposed as reduced-variation alternatives to traditional cross-validation (CV) methods based on sampling without replacement. Monte Carlo (MC) simulation studies aimed at estimating the true misclassification error conditional on the training set are commonly used to compare CV methods. We conducted an MC simulation study to compare a new method of bootstrap CV (BCV) to k-fold CV for estimating clasification error. Findings For the low-dimensional conditions simulated, the modest positive bias of k-fold CV contrasted sharply with the substantial negative bias of the new BCV method. This behavior was corroborated using a real-world dataset of prognostic gene-expression profiles in breast cancer patients. Our simulation results demonstrate some extreme characteristics of variance and bias that can occur due to a fault in the design of CV exercises aimed at estimating the true conditional error of a classifier, and that appear not to have been fully appreciated in previous studies. Although CV is a sound practice for estimating a classifier’s generalization error, using CV to estimate the fixed misclassification error of a trained classifier conditional on the training set is problematic. While MC simulation of this estimation exercise can correctly represent the average bias of a classifier, it will overstate the between-run variance of the bias. Conclusions We recommend k-fold CV over the new BCV method for estimating a classifier’s generalization error. The extreme negative bias of BCV is too high a price to pay for its reduced variance.

Abstract
The ability of iron to cycle reversibly between its ferrous and ferric oxidation states is essential for the biological functions of iron but may contribute to vascular injury through the generation of powerful oxidant species. We examined the association between chemical forms of iron that can participate in redox cycling, often referred to as "catalytic" or "labile" iron, and cardiovascular disease (CVD). In our cross-sectional study of 496 participants, 85 had CVD. Serum catalytic iron was measured using the bleomycin-detectable iron assay that detects biologically active iron. The odds of existing CVD for subjects in the upper third of catalytic iron were 10 times that of subjects with lower catalytic iron in unadjusted analyses. The association was decreased by 1/2 by age adjustment, but little additional attenuation occurred after adjusting for age, Framingham Risk Score, estimated glomerular filtration rate, hypertension status, high-density lipoprotein cholesterol, and systolic blood pressure, with the association remaining strong and significant (odds ratio 3.8, 95% confidence interval 1.4 to 10.1). In conclusion, we provide preliminary evidence for a strong detrimental association between high serum catalytic iron and CVD even after adjusting for several co-morbid conditions; however, broader prospective studies are needed to confirm these findings, which would support therapeutic trials to assess the beneficial effects of iron chelators on CVD.

Abstract
Nongonococcal urethritis (NGU), an inflammation of the urethra not caused by gonorrhea, is the most common urethritis syndrome seen in men in the United States. It is a sexually transmitted infection commonly caused by Chlamydia trachomatis, a pathogen which occurs more frequently in African-American men compared to white men. The purpose of this study was to investigate factors related to retention of study participants in a randomized, double-blinded clinical trial that evaluated four treatment regimens for the treatment of NGU. After the one-week treatment period, follow-up visits were scheduled during days 15-19 and days 35-45. Participants were phoned prior to scheduled appointments to encourage attendance, and contacted after missed appointments to reschedule their clinic visits. Of the 305 male study participants, 298 (98%) were African-American, 164 (54%) were 25 years of age or younger, and 80 (31%) had a post-secondary school education. The overall retention rate was 75%. Factors associated with study completion were educational level attained and clinical center. Participants with higher levels of education were more likely to complete the study. Clinical centers with the highest retention rates also provided the highest monetary incentives for participation. The retention rate for this study suggests that strategies are needed for improving the proportion of study participants that complete a clinical trial among young men with a sexually transmitted disease. These strategies may include increasing contacts with study participants to remind them of scheduled study visits using text messaging or social media and the use of financial incentives.

Abstract
BACKGROUND Human immunodeficiency virus type 1 (HIV-1)-infected men are at increased risk for anal cancer. Human papillomavirus (HPV) vaccination may prevent anal cancer caused by vaccine types. METHODS AIDS Malignancy Consortium Protocol 052 is a single-arm, open-label, multicenter clinical trial to assess the safety and immunogenicity of the quadrivalent HPV (types 6, 11, 16, and 18) vaccine in HIV-1-infected men. Men with high-grade anal intraepithelial neoplasia or anal cancer by history or by screening cytology or histology were excluded. Men received 0.5 mL intramuscularly at entry, week 8, and week 24. The primary end points were seroconversion to vaccine types at week 28, in men who were seronegative and without anal infection with the relevant HPV type at entry, and grade 3 or higher adverse events related to vaccination. RESULTS There were no grade 3 or greater adverse events attributable to vaccination among the 109 men who received at least 1 vaccine dose. Seroconversion was observed for all 4 types: type 6 (59 [98%] of 60), type 11 (67 [99%] of 68), type 16 (62 [100%] of 62), and type 18 (74 [95%] of 78). No adverse effects on CD4 counts and plasma HIV-1 RNA levels were observed. CONCLUSIONS The quadrivalent HPV vaccine appears safe and highly immunogenic in HIV-1-infected men. Efficacy studies in HIV-1-infected men are warranted. Clinical trials registration. NCT 00513526.
