RESUMEN

BACKGROUND: Heart failure is a prevailing diagnosis of hospitalization and readmission within 6 months, and nearly a quarter of these patients die within a year. Guideline-directed medication therapies reduce risk of mortality by 73% over 2 years; however, the implementation of these therapies to their target dose in clinical practice continues to be challenging. In 2020, the Veterans Affairs (VA) Health Care System developed a HF dashboard to monitor and improve outpatient HF management. The DASH-HF (Dashboard Activated Services and Telehealth for Heart Failure) study is a randomized, pragmatic clinical trial to evaluate proactive dashboard-directed telehealth clinics to improve the use and dosing of guideline-directed medication therapy for patients with heart failure with reduced ejection fraction not on optimal guideline-directed medication therapy within the VA. METHODS: Three hundred veterans with heart failure with reduced ejection fraction met inclusion criteria with an optimization potential score (OPS) of 5 or less out of 10, representing nonoptimal guideline-directed medication therapy. The primary outcome was a composite score of guideline-directed medical therapy, the OPS, 6 months after the end of the intervention. Secondary outcomes included active prescriptions for each individual guideline-directed medical therapy class, HF-related hospitalizations, deaths, and clinician time per patient during the intervention clinics. RESULTS: There was no significant difference between the intervention arm and usual care group in the primary outcome (OPS, 2.9; SD=2.1 versus OPS, 2.6, SD=2.1); adjusted mean difference 0.3 (95% CI, -0.1 to 0.7) or in the prespecified secondary outcomes for hospitalization and all-cause mortality for the intervention of proactive dashboard-based clinics. CONCLUSIONS: A dashboard-based clinic intervention did not improve the OPS or secondary outcomes of hospitalization and all-cause mortality. There remains a larger opportunity to better target patients and provide more intensive follow-up to further evaluate the utility of proactive dashboard-based clinics for HF management and quality improvement.

RESUMEN

BACKGROUND: Gaps in the receipt and dosing of guideline-directed medical therapy (GDMT) persist for patients with heart failure with reduced ejection fraction (HFrEF) [1]. In 2020, the Veterans Affairs (VA) developed a heart failure (HF) specific population dashboard to monitor care quality and performance on standard HFrEF performance measures [2]. METHODS: The Dashboard Activated Services and Telehealth for HF (DASH-HF) study is a pragmatic randomized quality improvement study designed to evaluate the utility of proactive population management clinics using the VA's HF dashboard to optimize GDMT for patients with HFrEF. Panel management telemedicine clinics incorporated multidisciplinary clinicians to perform chart review and impromptu telephone encounters to evaluate current HFrEF management and opportunities to optimize GDMT. The study will evaluate the efficacy of proactive panel management to usual care at 6 months as quantified by the GDMT optimization potential score. Secondary outcomes include hospitalizations, mortality, and clinician time per intervention. The study completed enrollment and randomization of 300 participants. The intervention was performed from September to December 2021. CONCLUSION: DASH-HF will contribute to the literature by evaluating use of the existing VA dashboard to identify HF patients with the lowest adherence to GDMT and proactively target this group for the intervention.

RESUMEN

Digital health has long been championed as a means to expanding access to health care. Now that the COVID-19 pandemic accelerated many health systems' integration of digital tools for care, digital health may provide a path towards more accessible stroke prevention and treatment, particularly for historically disadvantaged patient populations. Stroke management is composed of multiple time points where digital health innovations have the potential to augment health access and treatment: from primary prevention, to the time-sensitive detection of ischemic stroke, administration of thrombolytic agents and consideration for endovascular interventions, to appropriate post-acute care, rehabilitation, and lifelong secondary stroke prevention-stroke care relies on a multidisciplinary and standardized approach. However, as we discuss pointedly in this Focused Update, underrepresented individuals face multilevel digital health disparities that potentially diminish the benefits of these digital advances. As such, these multilevel needs must be discussed and accounted for as health systems seek to integrate innovative and equitable digital health solutions towards stroke care.

RESUMEN

PURPOSE: We compared the performance of multiparametric magnetic resonance imaging for the prediction of extraprostatic extension in African American and Caucasian American men and evaluated racial disparities in pathological outcomes after radical prostatectomy. MATERIALS AND METHODS: We identified 975 patients who underwent radical prostatectomy with preoperative multiparametric magnetic resonance imaging between January 2013 and April 2019 at our institution. Multivariable logistic regression analysis was performed predicting pathological extraprostatic extension, high grade prostate cancer (final pathology GGG [Gleason Grade Group] 3 or greater) in the overall population and pathological upgrading (final pathology GGG 3 or greater) in patients with a diagnosis of GGG 1-2 prostate cancer. Adverse pathology was defined as pT3 and/or GGG 3 or greater. RESULTS: A total of 221 (23%) patients were African American. Preoperatively 594 (60.9%) were GGG 1-2 (low risk group) and 381 (39.1%) GGG 3 or greater (high risk group). In the low risk group rates of pathological extraprostatic extension (18% vs 12.8%, p=0.14), adverse pathology (18% vs 13.4%, p=0.2) or upgrading (9.4% vs 12.1%, p=0.4) were similar between races. Similarly, in the high risk group there was no difference in rates of pathological extraprostatic extension. On multivariable analysis multiparametric magnetic resonance imaging predicted the presence of extraprostatic extension (OR 1.80, 95% CI 1.29-2.50) and high grade prostate cancer (OR 1.82, 95% CI 1.25-2.67) on final pathology. Conversely, race did not predict the outcomes of interest (all values p >0.05). Multiparametric magnetic resonance imaging showed comparable sensitivity (22.22% vs 27.84%), specificity (89.2% vs 79.2%), positive predictive value (89.2% vs 83.4%) and negative predictive value (89.2% vs 83.4%) between African American and Caucasian America men, respectively. CONCLUSIONS: The accuracy of multiparametric magnetic resonance imaging in staging prostate cancer was similar in African American and Caucasian American patients and no difference was found between races in pathological outcomes after radical prostatectomy. These findings suggest that access to and use of advanced diagnostic tests may help mitigate prostate cancer racial disparities.

RESUMEN

INTRODUCTION: We present a case of an Asian variant of intravascular large B-cell lymphoma associated with systemic and central nervous system hemophagocytic lymphohistiocytosis (HLH) with multiple neurologic manifestations. CASE PRESENTATION: A 68-year-old, previously healthy, Korean woman presented with a 4-week history of fever and weight loss. She had pancytopenia with neutropenia, a ferritin level of 5030 µg/L, and elevated liver enzyme levels. Bone marrow, liver biopsy specimens, and cerebrospinal fluid demonstrated hemophagocytosis. The patient was treated with the HLH-2004 protocol, but her disease relapsed 3 months later. A repeated liver biopsy specimen confirmed the initially missed diagnosis of intravascular large B-cell lymphoma, a known driver of HLH in patients of Asian origin. She was then treated with lymphoma-directed therapy and had a prompt resolution of fever and neurologic symptoms as well as normalization of her blood cell counts and ferritin level. DISCUSSION: This case serves as a reminder that patients with an Asian variant of intravascular large B-cell lymphoma frequently present with HLH and neurologic manifestations, including seizures, strokes, and cognitive deficits. A high index of suspicion is needed for prompt diagnosis and initiation of lymphoma-directed therapy.

RESUMEN

The decision-making process on behalf of unrepresented adults (ie, those who lack capacity to make medical decisions and have no identifiable surrogate) is at risk for not incorporating their interests, raising ethical concerns. We performed semistructured interviews with key stakeholders across multiple sectors in an urban county who participate in the care of or decision-making process for unrepresented adults. This included a safety net healthcare system, social services, and legal services. Participants were healthcare, social service, and legal professionals who worked with unrepresented adults (n = 25). Our interview questions explored the current process for proxy decision making in cases of unrepresented adults and potential alternatives. We recorded, transcribed, and analyzed interviews using the constant comparative method to identify major themes related to ethical challenges if they were raised. Participants grappled with multiple ethical challenges around the care of unrepresented adults. Themes described by participants were: (1) prioritizing autonomy; (2) varying safety thresholds; (3) distributing resources fairly; and (4) taking a moral toll on stakeholders. In conclusion, all stakeholders identified ethical challenges in caring for unrepresented adults. An applied ethical framework that takes these dilemmas into account could improve ethical practice for unrepresented adults and lessen the emotional toll on stakeholders.

RESUMEN

We demonstrate that Magnetic Particle Imaging (MPI) enables monitoring of cellular grafts with high contrast, sensitivity, and quantitativeness. MPI directly detects the intense magnetization of iron-oxide tracers using low-frequency magnetic fields. MPI is safe, noninvasive and offers superb sensitivity, with great promise for clinical translation and quantitative single-cell tracking. Here we report the first MPI cell tracking study, showing 200-cell detection in vitro and in vivo monitoring of human neural graft clearance over 87 days in rat brain.
