Stakeholder-led design of a mobile HIV clinic model to enhance engagement and retention in HIV care in the Southern United States.

To foster retention of people living with HIV (PLWH) in HIV care in the Southern United States, we aimed to develop a stakeholder-driven mobile HIV clinic (MHC) model. From June 2019 to May 2021 we conducted a mixed-methods study: 50 surveys with out-of-care PLWH and 41 in-depth interviews with PLWH, HIV clinic staff, city officials, AIDS service organizations, and mobile clinics to examine preferences for MHC implementation. Survey data was analyzed descriptively, and interview transcripts were coded thematically. Participants recommended the MHC: (1) have nondescript exterior and HIV services nested in non-HIV care to foster confidentiality, (2) be located along public transportation and have extended hours to promote accessibility, (3) have established protocols addressing security, biosafety, and data safety; (4) provide comprehensive clinical and support services to address retention barriers; and (5) be integrated within the health system, use low-cost, diverse staffing, and establish appointment notification systems. By informing MHC design, these findings add to the toolbox of strategies that can render HIV care more accessible.

Understanding and addressing privacy and confidentiality concerns associated with the provision of mobile HIV care: a qualitative study.

Less than half the people with HIV (PLWH) in the United States (US) are retained in HIV care, underscoring the importance of novel reengagement and retention strategies. Mobile HIV clinics (MHCs) are one such strategy, but privacy and confidentiality concerns have limited their use. As part of a larger mixed-methods study in Atlanta, Georgia, from June 2019- July 2020, we conducted 41 qualitative interviews with key stakeholders to explore confidentiality, privacy and stigma concerns and strategies to address them. Interviews were recorded, transcribed and coded thematically. Four key themes emerged: 1) the need to understand MHC acceptance in the context of high HIV stigma in the South, 2) the multidimensionality of confidentiality and stigma concerns (e.g., related to exterior labeling, layout, location attracting unwanted attention), 3) the counter perspective: potential for MHCs to positively reframe HIV and reduce stigma, and 4) strategies to overcome stigma and confidentiality concerns, including co-delivery of non-HIV services, unidirectional flow, and non-HIV exterior labeling. In furthering understanding of the breadth of privacy and confidentiality concerns associated with an MHC and strategies for addressing them, this exploratory study lays a critical foundation for the development of an MHC to reengage and retain PLWH in the US.

Stigma, discrimination, violence, and HIV testing among men who have sex with men in four major cities in Ghana.

LGBTQ populations experience human rights abuses worldwide; data need to document the health impact of these experiences in Africa. In Ghana, we measured events of sexuality-based stigma, discrimination, and violence among men who have sex with men (MSM) and the impact on HIV testing behavior. Data are from respondent-driven sampling surveillance surveys in Accra/Tema, Kumasi, Cape Coast/Takoradi, and Koforidua. Discrimination was common among MSM: 6.2%-30.6% were refused services, 29.0%-48.9% experienced verbal/symbolic violence, 2.8%-12.8% experienced physical violence, 12.3%-30.0% experienced sexual violence due to their sexuality in the preceding year. MSM who experienced sexual violence in their first male sexual encounter were less likely to ever test for HIV in Accra/Tema and Cape Coast/Takoradi. Further studies are needed to examine the impact of stigma and violence on MSM's HIV health-seeking behavior in Ghana. Structural interventions are needed to mitigate the consequences of stigma and discrimination on MSM health and well-being.

Bridging Health Disparities and Improving Reproductive Outcomes With Health Center-Affiliated Doula Programs.

Doulas are community perinatal professionals trained in pregnancy health, childbirth preparation, labor support, lactation counseling, and postnatal care. Doulas serve as patient advocates and provide laboring patients with continuous one-to-one support including informational, physical, and emotional support. Research shows that access to continuous labor support contributes to positive health outcomes such as increasing rates of spontaneous vaginal delivery, shorter labor, less need for analgesics, and increased satisfaction with the birthing process. However, despite their benefits, socioeconomic, structural, and systemic factors limit doula accessibility and manifest in low utilization among patients who could benefit from doulas the most. Given the positive health implications of doula support and the need for these services in underserved populations, there is an urgency to increase the accessibility of doulas. Several health centers in the United States have created successful doula programs to meet the needs of their patient populations. To better understand these programs, we interviewed and collaborated on this paper with program representatives from Boston Medical Center's Birth Sisters and DREAM: Delivery Resources, Education, and Advocacy for Moms; UNC Health's Birth Partners; and Michigan Medicine's Dial-A-Doula. Because many health centers serve as large public safety-net hospitals, having more health center-affiliated doula programs nationwide could be a positive step in bridging disparities and improving maternal and child health.

One size does not fit all: Preferences for HIV care delivery among out-of-care people living with HIV in the Southeastern United States.

Approximately half of the people with HIV (PWH) in the United States are retained in HIV care and only 57% have achieved viral suppression, due to barriers including transportation access, stigma, poor mental health, substance use, and medical mistrust. Community-based HIV care models have potential to address the diverse needs of patients and to improve retention in care, but their success is contingent on acceptance by patients and key community stakeholders. Recognizing that the preferences of PWH who are out-of-care (PWH-OOC) likely differ from those retained in care, we conducted a mixed-methods study from June 2019 to May 2021 composed of surveys with PWH-OOC (n = 50) and in-depth interviews with key clinic and community stakeholders (n = 41) to examine the relative preference and perceived advantages and disadvantages for six different community-based HIV care models versus the traditional fixed-clinic model. Survey data was analyzed to assess average rank preference for each care model and interview transcripts were thematically coded to examine factors influencing model acceptance. The highest preference for care delivery was via a mobile clinic, followed by community-based peer navigation, primary care clinics, telemedicine, traditional HIV subspeciality clinic, homeless shelter, and drug treatment center. Common factors influencing preference included convenience, accessibility, potential to preserve confidentiality, quality of care assurance, opportunity to develop rapport with their HIV care provider, access to a smart device, and potential to alleviate versus exacerbate HIV stigma. Participants discussed need for integration of care models and for individuals to choose different care models at different times. Providers and patients differed in preference for care model and weighting of relative advantages and disadvantages of each. Findings highlight the need to integrate alternative, community-based care models into the national plan to end the HIV epidemic and to allow for PWH-OOC to choose the model most fitting based on individual circumstances.

Reaching and Re-Engaging People Living with HIV Who Are Out of Care: A Mixed-Methods Exploration of Patient Preferences for Strategies to Enhance Clinic Communication and Outreach.

Half of all people living with HIV (PLWH) in the United States are not retained in HIV medical care. The utility of appointment reminders and clinic-based retention support services is often limited by the inability to contact PLWH who are out of care (PLWH-OOC) due to disconnected phone lines, full voice mails, and housing instability. Between June 2019 and May 2021, as part of a larger mixed-methods study in Metro Atlanta, Georgia, we conducted surveys with 50 PLWH-OOC and interviews with 13 PLWH holding a variety of clinic stakeholder roles (patients, Community Advisory Board members, and peer navigators) to explore preferences for clinic communication and peer outreach and factors impacting uptake. Although phone calls, text messages, and calling secondary contacts were most preferred, the spread of preferences was wide. Surveys and interviews highlighted the high acceptance of peer outreach visits, with trust, support, and privacy being key factors driving the uptake. Findings underscore the need for clinics to offer a suite of communication and outreach strategies and assess patient preferences for traditional and nontraditional outreach models to more effectively reach, re-engage, and ultimately retain PLWH-OOC.

Barriers and facilitators to use of a mobile HIV care model to re-engage and retain out-of-care people living with HIV in Atlanta, Georgia.

Novel strategies to re-engage and retain people living with HIV (PLWH) who are out of care are greatly needed. While mobile clinics have been used effectively for HIV testing and linkage, evidence guiding their use in providing HIV care domestically has been limited. To guide the development of a mobile HIV clinic (MHC) model as a strategy to re-engage and retain PLWH who are out of care, we aimed to explore stakeholder perceptions of barriers and facilitators to MHC implementation and use. From June 2019-July 2020, we conducted 41 in-depth interviews with HIV clinic providers, administrators, staff, legal authorities, and community advisory board members, PLWH, AIDS service organizations and city officials in Atlanta, Georgia, and domestic and international mobile health clinics to explore barriers and facilitators to use of MHCs. Interviews were transcribed, coded and thematically analysed. Barriers raised include potential for: breach of confidentiality with resulting heightened stigmatization, fractured continuity of care, safety concerns, staffing challenges, and low community acceptance of MHC presence in their locality. Participants provided suggestions regarding appropriate exterior design, location, timing, and co-delivery of non-HIV services that could facilitate MHC acceptance and address the concerns. In identifying key barriers and facilitators to MHC use, this study informs design and implementation of an MHC as a novel strategy for re-engaging and retaining PLWH who are out of care.

Upregulation of polycistronic microRNA-143 and microRNA-145 in colonocytes suppresses colitis and inflammation-associated colon cancer.

Because ADAM17 promotes colonic tumorigenesis, we investigated potential miRNAs regulating ADAM17; and examined effects of diet and tumorigenesis on these miRNAs. We also examined pre-miRNA processing and tumour suppressor roles of several of these miRNAs in experimental colon cancer. Using TargetScan, miR-145, miR-148a, and miR-152 were predicted to regulate ADAM17. miR-143 was also investigated as miR-143 and miR-145 are co-transcribed and associated with decreased tumour growth. HCT116 colon cancer cells (CCC) were co-transfected with predicted ADAM17-regulating miRNAs and luciferase reporters controlled by ADAM17-3'UTR. Separately, pre-miR-143 processing by colonic cells was measured. miRNAs were quantified by RT-PCR. Tumours were induced with AOM/DSS in WT and transgenic mice (Tg) expressing pre-miR-143/miR-145 under villin promoter. HCT116 transfection with miR-145, -148a or -152, but not scrambled miRNA inhibited ADAM17 expression and luciferase activity. The latter was suppressed by mutations in ADAM17-3'UTR. Lysates from colonocytes, but not CCC, processed pre-miR-143 and mixing experiments suggested CCC lacked a competency factor. Colonic miR-143, miR-145, miR-148a, and miR-152 were downregulated in tumours and more moderately by feeding mice a Western diet. Tg mice were resistant to DSS colitis and had significantly lower cancer incidence and tumour multiplicity. Tg expression blocked up-regulation of putative targets of miR-143 and miR-145, including ADAM17, K-Ras, XPO5, and SET. miR-145, miR-148a, and miR-152 directly suppress colonocyte ADAM17 and are down-regulated in colon cancer. This is the first direct demonstration of tumour suppressor roles for miR-143 and miR-145 in an in vivo model of colonic tumorigenesis.

A case of Good's syndrome complicated by erythema multiforme.

Good's syndrome (GS) is a rare, adult-onset combined B cell and T cell immunodeficiency with an associated thymoma. These patients have an increased risk of bacterial, fungal, viral and opportunistic infections. This report describes a 75-year-old female patient who presented with a full body rash and an anterior mediastinal mass. She underwent a biopsy of her rash and mass, which revealed erythema multiforme and WHO Type A thymoma, respectively. During her hospitalisation, she was also found to have oropharyngeal candidiasis, methicillin-susceptible Staphylococcus aureus bacteraemia and herpes simplex virus type 2 (HSV-2) skin lesions. Based on the number of infections and severity of her rash, an immunocompromised state was suspected. Immunological testing revealed a B cell and T cell deficiency as well as low serum immunoglobulins. This combination of hypogammaglobulinaemia and thymoma led to a diagnosis of GS. While there have been many case reports of GS, this is the first report of the immunodeficiency presenting with erythema multiforme.

ADAM17 is a Tumor Promoter and Therapeutic Target in Western Diet-associated Colon Cancer.

PURPOSE: Epidermal growth factor receptors (EGFR) are required for tumor promotion by Western diet. The metalloprotease, ADAM17 activates EGFR by releasing pro-EGFR ligands. ADAM17 is regulated by G-protein-coupled receptors, including CXCR4. Here we investigated CXCR4-ADAM17 crosstalk and examined the role of ADAM17 in tumorigenesis. EXPERIMENTAL DESIGN: We used CXCR4 inhibitor, AMD3100 and ADAM17 inhibitor, BMS566394 to assess CXCR4-ADAM17 crosstalk in colon cancer cells. We compared the expression of CXCR4 ligand, CXCL2, and ADAM17 in mice fed Western diet versus standard diet. Separately, mice were treated with marimastat, a broad-spectrum ADAM17 inhibitor, or AMD3100 to assess EGFR activation by ADAM17 and CXCR4. Using Apc-mutant Min mice, we investigated the effects of ADAM17/10 inhibitor INCB3619 on tumorigenesis. To assess the effects of colonocyte ADAM17, mice with ADAM17 conditional deletion were treated with azoxymethane (AOM). ADAM17 expression was also compared in colonocytes from primary human colon cancers and adjacent mucosa. RESULTS: CXCL12 treatment activated colon cancer cell EGFR signals, and CXCR4 or ADAM17 blockade reduced this activation. In vivo, Western diet increased CXCL12 in stromal cells and TGFα in colonocytes. Marimastat or AMD3100 caused >50% reduction in EGFR signals (P < 0.05). In Min mice, INCB3619 reduced EGFR signals in adenomas and inhibited intestinal tumor multiplicity (P < 0.05). In the AOM model, colonocyte ADAM17 deletion reduced EGFR signals and colonic tumor development (P < 0.05). Finally, ADAM17 was upregulated >2.5-fold in human malignant colonocytes. CONCLUSIONS: ADAM17 is a Western diet-inducible enzyme activated by CXCL12-CXCR4 signaling, suggesting the pathway: Western diet→CXCL12→CXCR4→ADAM17→TGFα→EGFR. ADAM17 might serve as a druggable target in chemoprevention strategies. Clin Cancer Res; 23(2); 549-61. ©2016 AACR.

Florida Initiative for Quality Cancer Care: improvements on colorectal cancer quality of care indicators during a 3-year interval.

BACKGROUND: The quality of cancer care has become a national priority; however, there are few ongoing efforts to assist medical oncology practices in identifying areas for improvement. The Florida Initiative for Quality Cancer Care is a consortium of 11 medical oncology practices that evaluates the quality of cancer care across Florida. Within this practice-based system of self-assessment, we determined adherence to colorectal cancer quality of care indicators (QCIs) in 2006, disseminated results to each practice and reassessed adherence in 2009. The current report focuses on evaluating the direction and magnitude of change in adherence to QCIs for colorectal cancer patients between the 2 assessments. STUDY DESIGN: Medical records were reviewed for all colorectal cancer patients seen by a medical oncologist in 2006 (n = 489) and 2009 (n = 511) at 10 participating practices. Thirty-five indicators were evaluated individually and changes in QCI adherence over time and by site were examined. RESULTS: Significant improvements were noted from 2006 to 2009, with large gains in surgical/pathological QCIs (eg, documenting rectal radial margin status, lymphovascular invasion, and the review of ≥ 12 lymph nodes) and medical oncology QCIs (documenting planned treatment regimen and providing recommended neoadjuvant regimens). Documentation of perineural invasion and radial margins significantly improved; however, adherence remained low (47% and 71%, respectively). There was significant variability in adherence for some QCIs across institutions at follow-up. CONCLUSIONS: The Florida Initiative for Quality Cancer Care practices conducted self-directed quality-improvement efforts during a 3-year interval and overall adherence to QCIs improved. However, adherence remained low for several indicators, suggesting that organized improvement efforts might be needed for QCIs that remained consistently low over time. Findings demonstrate how efforts such as the Florida Initiative for Quality Cancer Care are useful for evaluating and improving the quality of cancer care at a regional level.

Florida Initiative for Quality Cancer Care: improvements in breast cancer quality indicators during a 3-year interval.

BACKGROUND: The Florida Initiative for Quality Cancer Care (FIQCC), composed of 11 practice sites across Florida, conducted its initial evaluation of adherence to breast cancer quality of care indicators (QCI) in 2006, with feedback provided to encourage quality improvement efforts at participating sites. In this study, our objective was to reassess changes over time resulting from these efforts. STUDY DESIGN: Quality care indicators were derived from the Quality Oncology Practice Initiative, the National Comprehensive Cancer Network, the American College of Surgeons, and expert panel consensus. Medical records were reviewed for breast cancer patients first seen by medical oncologists in 2009 at the FIQCC sites, using the same performance indicators as in 2006. Statistical comparisons of 2006 vs 2009 data across sites were made by Pearson chi-square exact test using Monte Carlo estimation. RESULTS: Charts of 602 patients in 2006 and 636 patients in 2009 were compared. Performance on medical oncology QCI improved over time for documentation of clinical trial participation discussion (p = 0.001), documentation of consent for chemotherapy (p = 0.047), definitive surgery done after neoadjuvant chemotherapy (p = 0.017), and planned dose of chemotherapy consistent with published regimens (p = 0.02). Improvements in surgical QCI were seen for documentation of specimen orientation (p < 0.001), inking of margins (p < 0.0001), and performance of sentinel lymph node biopsy (p = 0.035). CONCLUSIONS: The 2006 FIQCC study identified several medical and surgical oncology QCI improvement needs. Quality improvement efforts resulted in better performance for numerous metrics, therefore speaking to the benefits of reassessment of adherence to performance indicators to guide QCI efforts.

Development of a cancer clinical trials multi-media intervention: clinical trials: are they right for you?

OBJECTIVE: To describe processes used to develop a multi-media psycho-educational intervention to prepare patients for a discussion about cancer clinical trials (CTs). METHODS: Guided by a Steering Committee, formative research was conducted to develop an informative and engaging tool about cancer CTs. Twenty-three patients and caregivers participated in formative in-depth interviews to elicit information about perceptions of cancer CTs to inform production of a new media product. RESULTS: Formative research revealed participants had concerns about experimentation, held beliefs that cancer CTs were for patients who had no other treatment options, and wanted a balance of information about pros and cons of CT participation. The value of physicians as credible spokespersons and the use of patients as role-models were supported. Using iterative processes, the production team infused the results into creation of a multimedia psycho-educational intervention titled Clinical Trials: Are they Right for You? CONCLUSION: An intervention, developed through an iterative consumer-focused process involving multiple stakeholders and formative research, may result in an engaging informative product. PRACTICE IMPLICATIONS: If found to be efficacious, Clinical Trials: Are they Right for You? is a low-cost and easily disseminated multimedia psycho-educational intervention to assist cancer patients with making an informed decision about cancer CTs.

Evaluating the quality of colorectal cancer care in the state of Florida: results from the Florida Initiative for Quality Cancer Care.

PURPOSE: The Florida Initiative for Quality Cancer Care (FIQCC) was established to evaluate the quality of cancer care at the regional level across the state of Florida. This study assessed adherence to validated quality indicators in colorectal cancer (CRC) and the variability in adherence by practice site, volume, and patient age. METHODS: The FIQCC is a consortium of 11 medical oncology practices in Florida. Medical record reviews were conducted for 507 patients diagnosed with CRC and seen as new medical oncology patients in 2006. Thirty-five indicators were evaluated individually and categorized across clinical domains and components of care. RESULTS: The mean adherence for 19 of 35 individual indicators was > 85%. Pathology reports were compliant on reporting depth of tumor invasion (96%; range, 86% to 100%), grade (93%; range, 72% to 100%), and status of proximal and distal surgical resection margins (97%; range. 86% to 100%); however, documentation of lymphovascular and perineural invasion did not meet adherence standards (76%; range, 53% to 100% and 39%; range, 5% to 83%, respectively). Among patients with nonmetastatic rectal cancer, documentation of the status of surgical radial margins was consistently low across sites (42%; range, 0% to 100%; P = .19). Documentation of planned treatment regimens for adjuvant chemotherapy was noted in only 58% of eligible patients. CONCLUSION: In this large regional initiative, we found high levels of adherence to more than half of the established quality indicators. Although the quality of care delivered within FIQCC practices seems to be high, several components of care were identified that warrant further scrutiny on both a systemic level and at individual centers.

Degree of variability in performance on breast cancer quality indicators: findings from the Florida initiative for quality cancer care.

PURPOSE: The Florida Initiative for Quality Cancer Care (FIQCC) comprises 11 Florida practice sites that participate in comprehensive reviews of quality of care specific to patients with cancer. Here, we examined site adherence to performance indicators to assess quality of care for patients with breast cancer (BC). METHODS: Quality indicators were scripted on the basis of accepted guidelines from the Quality Oncology Practice Initiative, National Comprehensive Cancer Network, American College of Surgeons, and site-specific expert panel consensus. Comprehensive chart reviews, including both medical and surgical oncology quality measures, were conducted for patients with BC first seen in 2006 by a medical oncologist at one of the sites. Statistical comparisons were made by the Pearson χ(2) exact test, using Monte Carlo estimation. RESULTS: Charts of 622 patients were reviewed. Of the 34 indicators, seven for medical oncology and four for surgical oncology fell below the 85% level of adherence. A statistically significant difference (P < .001) in variation of performance across the sites was found for the following medical and surgical oncology indicators: documentation of menopausal status, family history, informed consent, planned chemotherapy regimen and flow sheet, American Joint Committee on Cancer staging, HER2/neu status, reporting of margin orientation and inking of the margins, histological grade, having a sentinel lymph node biopsy for invasive BC, and obtaining a mammogram within 14 months of definitive surgery. CONCLUSION: The FIQCC has identified how multiple aspects of BC care can be improved. Findings are being used at the participating institutions to guide quality improvement efforts.

Imaging in sports medicine: an overview.

Increasing sports participation, and the inevitable sports injury, is a significant contributor to total healthcare expenditure in the United States. With sports-related injury ever increasing, and technology rapidly expanding in the areas of diagnosis and treatment of musculoskeletal trauma, a continual revisiting of the latest in technology is critical for the sports physician. Advances particularly in the areas of magnetic resonance imaging, diagnostic office ultrasound, and 3-dimensional reconstruction computed tomography, offer the clinician a myriad of diagnostic options in patient evaluation. Care must be exercised, however, as one pursues additional radiographic data in the patient care arena. The information must be interpreted with a firm foundation and understanding of not only the patient history and physical examination, but also the availability, indications, contraindications, sensitivity, specificity, and even the cost implications of the great spectrum of diagnostic options.

Relative contributions of organochlorine contaminants, parasitism, and predation to reproductive success of eastern spiny softshell turtles (Apalone spiniferus spiniferus) from southern Ontario, Canada.

We examined hatching success, predation rates, rates of parasitism, sex ratio, and egg viability in eggs of the eastern spiny softshell (Apalone spiniferus spiniferus), a threatened species in Canada. Eggs were monitored from three populations, located at Thames River, Rondeau Provincial Park, and the Long Point National Wildlife Area, in southern Ontario, Canada in 1998. Concurrently, we measured organochlorine pesticides, PCBs, dibenzo-p-dioxins and furans from eggs from the same nests. Contaminant concentrations in eggs were similar among sites. There was no correlation between hatching success, parasitism and depredation rates, or the proportion of hatchlings that were males with total PCBs or individual pesticides, but there was a positive correlation between egg viability with concentrations in eggs of total PCBs, and with five pesticides. We found no evidence that the reproductive success of softshell turtles was compromised due to organochlorine contamination. The most important factors determining hatching success of eggs was predation, followed by egg viability and parasitism.
