Participant experiences in HIV cure-directed trial with an extended analytical treatment interruption in Philadelphia, United States.

BACKGROUND: A feature of HIV cure trials is the need to interrupt treatment to test the efficacy of experimental interventions-a process known as analytical treatment interruptions (ATIs). OBJECTIVES: We report the experiences of participants after they completed an extended ATI. METHODS: From April to November 2022, we conducted post-ATI in-depth interviews with BEAT2 clinical trial (NCT03588715) participants who stopped ART while receiving an immunotherapy regimen. We used conventional content analysis to code the data. RESULTS: We conducted interviews with 11 Black/African American and three White/Caucasian participants (11 males, two females, and one transgender woman). The mean ATI was 38 weeks. Participants noted several significant experiences surrounding the interventions' side effects, ATI, and returning to medication. Some participants had positive experiences with their ATI. Other participants were nervous during the ATI. Rising viral loads led some to feel a sense of failure. Although trial experiences were heterogeneous, participants unanimously had positive interactions with the clinical trial staff which facilitated their retention in the trial. Participants shared their experiences with the trial, including changes in expectations, experiences with experimental interventions and procedures, compensation as a measure of respect, effort, transportation, and effects of COVID-19 during the trial. Based on these results, we provide considerations for the conduct of future HIV cure-directed clinical trials involving ATIs. CONCLUSIONS: Managing expectations, focusing on participants' contributions, and providing support to reduce feelings of having failed the research team and/or the HIV community following viral rebound should be part of HIV cure trial design. Discussing the mental health impact of rebound during consent, distinct from risk, is needed. Continued efforts to understand how people with HIV experience ATIs will improve future designs of HIV cure clinical trials.

A partner protection package for HIV cure-related trials involving analytical treatment interruptions.

Analytical treatment interruptions (ATIs) have become a key methodological approach to evaluate the effects of experimental HIV cure-related research interventions. During ATIs, sex partners of trial participants might be at risk of acquiring HIV. This risk raises both ethical and feasibility concerns about ATI trials. We propose a partner protection package (P3) approach to address these concerns. A P3 approach would provide guidance to investigators, sponsors, and those who are designing and implementing context-specific partner protections in HIV cure-related trials involving ATIs. The approach would also help assure institutional review boards, trial participants, and communities that ATI trials with a P3 would provide appropriate partner protections. We offer a prototype P3 framework that delineates three basic considerations for protecting participants' sex partners during ATI trials: (1) ensuring the scientific and social value of the ATI and the trial, (2) reducing the likelihood of unintended HIV transmission, and (3) ensuring prompt management of any acquired HIV infection. We outline possible ways of implementing these basic considerations.

Community engagement group model in basic and biomedical research: lessons learned from the BEAT-HIV Delaney Collaboratory towards an HIV-1 cure.

INTRODUCTION: Achieving effective community engagement has been an objective of U.S. National Institutes of Health-funded HIV research efforts, including participation of persons with HIV. Community Advisory Boards (CABs) have remained the predominant model for community engagement since their creation in 1989. As HIV cure-directed research efforts have grown into larger academic-industry partnerships directing resources toward both basic and clinical research under the Martin Delaney Collaboratories (MDC), community input models have also evolved. The BEAT-HIV MDC Collaboratory, based at The Wistar Institute in Philadelphia, United States, implemented a three-part model for community engagement that has shown success in providing greater impact for community engagement across basic, biomedical, and social sciences research efforts. DISCUSSION: In this paper, we review the case study of the formation of the BEAT-HIV Community Engagement Group (CEG) model, starting with the historical partnership between The Wistar Institute as a basic research center and Philadelphia FIGHT as a not-for-profit community-based organization (CBO), and culminating with the growth of community engagement under the BEAT-HIV MDC. Second, we present the impact of a cooperative structure including a Community Advisory Board (CAB), CBO, and researchers through the BEAT-HIV CEG model, and highlight collaborative projects that demonstrate the potential strengths, challenges, and opportunities of this model. We also describe challenges and future opportunities for the use of the CEG model. CONCLUSIONS: Our CEG model integrating a CBO, CAB and scientists could help move us towards the goal of effective, equitable and ethical engagement in HIV cure-directed research. In sharing our lessons learned, challenges and growing pains, we contribute to the science of community engagement into biomedical research efforts with an emphasis on HIV cure-directed research. Our documented experience with implementing the CEG supports greater discussion and independent implementation efforts for this model to engage communities into working teams in a way we find a meaningful, ethical, and sustainable model in support of basic, clinical/biomedical, social sciences and ethics research.

HIV biomedical research groups have prioritized community support and representation as exemplified by the creation of Community Advisory Boards (CABs). Most CABs bring diverse stakeholders to advise on research objectives as part of their activities. The BEAT-HIV Delaney Collaboratory, based at The Wistar Institute in Philadelphia, is a research program created in 2016 to advance HIV cure research. To better engage communities beyond the CAB, the BEAT-HIV Delaney Collaboratory created a Community Engagement Group (CEG) model composed of three distinct components. First, the involvement of a community-based organization (CBO) introduces the historical know-how and relationship with the community. Philadelphia FIGHT fulfills the CBO role as a provider of primary care, education, advocacy, and research support for persons with HIV. Second, the BEAT-HIV CAB provides individual experiences and community input into HIV cure research and gives updates to the broader community about the status of research. Third, basic, clinical/biomedical, and social scientists implement the scientific goals of the BEAT-HIV Collaboratory. In this paper, we aimed to highlight the strengths, challenges, lessons learned, and opportunities of the BEAT-HIV CEG model. We also present examples of collaborative community engagement projects. Our paper contributes to the literature on novel community engagement approaches beyond the CAB. Based on our experience to date using the CEG, a multi-part community engagement model could help move us towards the goal of inclusive, effective, equitable, and ethical engagement in HIV cure research.

Participant experiences using novel home-based blood collection device for viral load testing in HIV cure trials with analytical treatment interruptions

Background: HIV cure-directed clinical trials using analytical treatment interruptions (ATIs) require participants to adhere to frequent monitoring visits for viral load tests. Novel viral load monitoring strategies are needed to decrease participant burden during ATIs.Objective: To examine acceptability of a novel home-based blood collection device for viral load testing in the context of two ongoing ATI trials in Philadelphia, PA, United States.Methods: From January 2021 to February 2022, participants completed three in-depth interviews via teleconference during their participation in an ATI: (1) within two weeks of enrollment in the device study, (2) approximately four weeks after beginning to use the device, and (3) within two weeks of the end of the ATI when ART was re-initiated. We used conventional content analysis to analyze the data.Results: We recruited 17 participants: 15 were cisgender males, 1 cisgender female, and 1 transgender woman. We observed an overall 87% success rate in drawing blood with the device from home collection and found overall high acceptance of the device. A mean of 91.5 devices per participant were used for home-based blood collection. Most PWH viewed the device as relatively convenient, painless, easy to use, and a simple solution to frequent blood draws. The main challenge encountered was the inability to completely fill up devices with blood in some cases. Most participants reported positive experiences with mailing blood samples and could see themselves using the device on a regular basis outside of ATIs.Conclusions: Our study showed participant valued the novel home-based peripheral blood collection for viral load testing in the context of ATI trials. More research will be necessary to optimize implementation of the device and to assess whether blood collected can reliably measure viral loads in the context of ATI trials.

Outcomes of Abbreviated MRI (Ab-MRI) for Women of any Breast Cancer Risk and Breast Density in a Community Academic Setting.

BACKGROUND: Abbreviated magnetic resonance imaging (Ab-MRI) has been evaluated for elevated breast cancer risk or dense breasts but has not been evaluated across all risk profiles. METHODS: Patients selected underwent Ab-MRI from February 2020 to September 2021. Women were older than aged 30 years, up to date with screening mammography, and paid $299 cash. RESULTS: A total of 93 patients were identified with a mean age of 52 years; 92.5% were Caucasian, 0% black, and 97.9% were from high socioeconomic status. Mean Gail score was 14.2, and 83.3% had a lifetime risk of breast cancer <20%. Reasons for Ab-MRI: dense breasts (36.6%); family history (24.7%); palpable mass (12.9%). Providers ordering: OBGYN (49.5%); breast surgeon (39.1%); primary care (6.6%). Thirteen biopsies (14%) detected one breast cancer. 31.1% had a change in follow-up screening: 58.6% 6-month MRI, 20.7% 6-month mammogram, and 10.3% 6-month ultrasound. Negative predictive value was 100% (95% confidence interval [CI]: 95-100%, p < 0.0001). Sensitivity was 100% (95% CI: 2.5-100%, p < 0.0001), and specificity was 87% (95% CI: 78.3-93.1%, p < 0.0001) compared with 77.6% and 98.8% for mammography. Only one cancer was detected: cost of $27,807 plus cost of 13 MRI or ultrasound (US)-guided biopsies and additional follow-up imaging. Historically 20% of abnormalities detected on full MRI are malignant; however, 7.7% of ab-MRI abnormalities were malignant CONCLUSIONS: One third of women were recommended a change in follow-up, which predominantly included a 6-month MRI. Ab-MRI may introduce average risk women to unnecessary follow-up and increased biopsies with a lower cancer detection rate. Ab-MRI should be evaluated closely before implementation.

"We are looking at the future right now": community acceptability of a home-based viral load test device in the context of HIV cure-related research with analytical treatment interruptions in the United States.

BACKGROUND: People with HIV (PWH) and community members have advocated for the development of a home-based viral load test device that could make analytical treatment interruptions (ATIs) less burdensome. OBJECTIVE: We assessed community acceptability of a novel home-based viral load test device. METHODS: In 2021, we conducted 15 interviews and 3 virtual focus groups with PWH involved in HIV cure research. We used conventional thematic analysis to analyze the data. RESULTS: PWH viewed the home-based viral load test device as a critical adjunct in ongoing HIV cure trials with ATIs. The ability to test for viral load at home on demand would alleviate anxiety around being off ART. Participants drew parallels with glucometers used for diabetes. A preference was expressed for the home-based test to clearly indicate whether one was detectable or undetectable for HIV to mitigate risk of HIV transmission to partners. Perceived advantages of the device included convenience, sense of control, and no puncturing of veins. Perceived concerns were possible physical marks, user errors and navigating the logistics of mailing samples to a laboratory and receiving test results. Participants expressed mixed effects on stigma, such as helping normalize HIV, but increased potential for inadvertent disclosure of HIV status or ATI participation. Increasing pluri-potency of the device beyond viral load testing (e.g., CD4+ count test) would increase its utility. Participants suggested pairing the device with telemedicine and mobile health technologies. CONCLUSIONS: If proven effective, the home-based viral load test device will become a critical adjunct in HIV cure research and HIV care.

Preliminary Acceptability of a Home-Based Peripheral Blood Collection Device for Viral Load Testing in the Context of Analytical Treatment Interruptions in HIV Cure Trials: Results from a Nationwide Survey in the United States.

Frequent viral load testing is necessary during analytical treatment interruptions (ATIs) in HIV cure-directed clinical trials, though such may be burdensome and inconvenient to trial participants. We implemented a national, cross-sectional survey in the United States to examine the acceptability of a novel home-based peripheral blood collection device for HIV viral load testing. Between June and August 2021, we distributed an online survey to people with HIV (PWH) and community members, biomedical HIV cure researchers and HIV care providers. We performed descriptive analyses to summarize the results. We received 73 survey responses, with 51 from community members, 12 from biomedical HIV cure researchers and 10 from HIV care providers. Of those, 51 (70%) were cisgender men and 50 (68%) reported living with HIV. Most (>80% overall) indicated that the device would be helpful during ATI trials and they would feel comfortable using it themselves or recommending it to their patients/participants. Of the 50 PWH, 42 (84%) indicated they would use the device if they were participating in an ATI trial and 27 (54%) also expressed a willingness to use the device outside of HIV cure studies. Increasing sensitivity of viral load tests and pluri-potency of the device (CD4 count, chemistries) would augment acceptability. Survey findings provide evidence that viral load home testing would be an important adjunct to ongoing HIV cure-directed trials involving ATIs. Survey findings may help inform successful implementation and uptake of the device in the context of personalized HIV care.

COVID-19 Pandemic: Changes in Care for a Community Academic Breast Center and Patient Perception of Those Changes.

BACKGROUND: Philadelphia and its suburbs were an epicenter for the initial COVID-19 outbreak. Accordingly, alterations were made in breast cancer care at a community hospital. METHODS: The authors developed a prospective database of all the patients with invasive or in situ breast cancer between March 1 and June 15 at their breast center. Any change in a breast cancer plan due to the pandemic was documented, and the patients were grouped into two cohorts according to whether a change was made (CTX) or no change was made (NC) in their care. The patients were asked a series of questions about their care, including those in the Generalized Anxiety Disorder two-item questionnaire (GAD-2), via telephone. RESULTS: The study enrolled 73 patients: 41 NC patients (56%) and 32 CTX patients (44%). The two cohorts did not differ in terms of age, race, or stage. Changes included delay in therapy (15.1%) and use of neoadjuvant endocrine therapy (NET, 28.8%). The median time to surgery was 24 days (interequartile range [IQR], 16-45 days) for the NC patients and 82 day s (IQR, 52-98 days) for the CTX patients (p ≤ 0.001). The median duration of NET was 78 days. The GAD-2 showed anxiety positivity to be 29.6% for the CTX patients and 32.4% for the NC patients (p = 1.00). More than half (55.6%) of the CTX patients believed COVID-19 affected their treatment outlook compared with 25.7% of the NC patients (p = 0.021). CONCLUSIONS: A prospective database captured changes in breast cancer care at a community academic breast center during the initial phase of the COVID-19 pandemic. 44% of patients experienced a change in breast cancer care due to COVID-19. The same level of anxiety and depression was seen in both change in therapy (CTX) and no change (NC). 55.6% of CTX cohort believed COVID-19 affected their treatment outlook.

Metabolic Syndrome: does this influence breast cancer outcomes in the triple-negative population?

INTRODUCTION: Metabolic syndrome (MS) is defined by having at least 3 of 4 components: obesity, dyslipidemia, hypertension (HTN), and diabetes. Prior studies analyzed the individual components of MS for all breast cancers which are predominantly hormone positive. Our study is the first to evaluate MS in triple-negative breast cancer (TNBC). METHODS: A retrospective review of TNBC from 2007 to 2013 identified 177 patients with complete information for statistical analysis. Cox proportional hazards models were used to test the association between MS, disease-free survival (DFS), and overall survival (OS). RESULTS: 48 (27%) patients had MS. After controlling for age, race, pathologic stage, surgery type, and additional comorbidities outside of MS, MS was significantly associated with poorer DFS (adjusted HR: 2.24, p = 0.030), but not associated with OS (adjusted HR: 1.92, p = 0.103). HTN was significantly associated with poorer DFS (adjusted HR: 3.63, p = 0.006) and OS (adjusted HR: 3.45, p = 0.035) in the univariable and multivariable analyses. Diabetes was not associated with worse OS or DFS. The 5-year age-adjusted OS rates for 60-year-old patients with and without diabetes were 85.8% and 87.3%, respectively. The age-adjusted 5-year OS rate for 60-year old patients was higher in patients with a body mass index (BMI) > 30 (90.2%) versus BMIs of 25-29.9 (88.2%) or < 25 (83.5%). CONCLUSION: In the TNBC population, MS was significantly associated with poorer DFS, but not associated with OS. HTN was the only component of MS that was significantly associated with both DFS and OS. Obesity has a potential small protective benefit in the TNBC population.

Additive manufacturing of polymer-derived ceramics.

The extremely high melting point of many ceramics adds challenges to additive manufacturing as compared with metals and polymers. Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. We report preceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture. These polymer structures can be pyrolyzed to a ceramic with uniform shrinkage and virtually no porosity. Silicon oxycarbide microlattice and honeycomb cellular materials fabricated with this approach exhibit higher strength than ceramic foams of similar density. Additive manufacturing of such materials is of interest for propulsion components, thermal protection systems, porous burners, microelectromechanical systems, and electronic device packaging.

Health-related quality of life, depressive symptoms, anemia, and malnutrition at hemodialysis initiation.

BACKGROUND AND METHODS: We administered the Kidney Disease Quality of Life (KDQOL) short form and a three-item depression screening measure derived from the Diagnostic Interview Schedule to 422 new patients with end-stage renal disease (ESRD; incident cohort) who began maintenance hemodialysis (HD) therapy at 151 outpatient dialysis facilities across the United States. RESULTS: At HD therapy initiation, 56% of patients had hemoglobin levels less than 10 g/dL (100 g/L), and 52% had albumin levels of 3.5 g/dL (35 g/L) or less. The 36-Item Short Form Health Survey (SF-36) scores (part of the KDQOL) for this incident cohort were significantly lower than those of a prevalent HD cohort and a severe chronic disease cohort (P < 0.01 to 0.001), and physical health scores were among the lowest ever reported. SF-36 summary scores were 2 SDs below those of an age- and sex-adjusted US general population in physical health and half an SD below those in mental health. Patients who screened positive for depression (45% of sample) scored even lower on all eight SF-36 scale scores and 9 of 12 of the KDQOL kidney disease-targeted scales (P < 0.05 to 0.01), but did not differ from nondepressed patients on demographic, clinical, or laboratory study variables. CONCLUSION: The extent to which the profound impairment documented in this study can be improved by more timely high-quality predialysis care requires further investigation. Nevertheless, the high prevalence of anemia, hypoalbuminemia, and depressive symptoms at dialysis therapy initiation suggests the need for more aggressive and broader spectrum pre-ESRD care.

Impact of age and colony-stimulating factor use on hospital length of stay for febrile neutropenia in CHOP-treated non-Hodgkin's lymphoma.

BACKGROUND: In intermediate-grade non-Hodgkin's lymphoma (NHL) patients, full-dose CHOP improves survival but increases myelosuppression, causing febrile neutropenia hospitalization (FNH) in 28% of patients 65 years of age or greater. Several risk factors for FNH are known, but their relationship to length of stay (LOS), an indicator of the total burden of FNH, is unclear. METHODS: We conducted a study to identify factors associated with the incidence, recurrence, and duration of hospitalizations for FN and to describe the frequency of administration of colony-stimulating factor (CSF) as primary and secondary prophylaxis and its association with repeated hospitalization episodes. RESULTS: Compared with patients who did not experience hospitalizations for FN, those who did were significantly older, had more comorbid conditions, were planned for standard dose intensity, and received CSF less often during the first 5 days of cycle 1 (early CSF). Overall, 73% of these hospitalizations occurred within the first 2 cycles of chemotherapy, with 56% occurring within the first cycle. Patients age > or = 65 years accounted for 66% of cycle 1 FNH. Patients receiving early CSF were less likely to experience repeated hospitalizations (0% vs 12%; P<.05). Multiple regression analysis of those hospitalized found a 3.9-day longer LOS for patients age > or = 65 years and a 5.13-day longer LOS for those not receiving early CSF. CONCLUSIONS: Older NHL patients have a higher risk of hospitalization for FN and longer LOS. The majority of hospitalization days occur in the first 2 cycles of chemotherapy. Early CSF use is associated with decreased risk of repeated hospitalizations and shorter total LOS. Secondary CSF use is also associated with reduced risk of repeated FNH.
