Background: Childhood cancer survivors (CCS) have a 50% higher risk of diabetes mellitus (DM) compared with the general population. Interventions in survivors with prediabetes (fasting glucose 100-125 mg/dL or hemoglobin A1c 5.7%-6.4%) may mitigate the development of DM and its attendant morbidity, but there is limited information on the feasibility of secondary prevention in this setting., Methods: This 6-week pilot feasibility 1:1 randomized controlled trial enrolled 20 CCS on a structured telehealth exercise program ± nicotinamide riboside (NR), a nicotinamide adenine dinucleotide precursor. Feasibility metrics were: (1) ≥50% of eligible CCS enrolled onto study; (2) ≥70% of participants completed baseline and end-of-study assessments; (3) ≥70% compliance with exercise and NR. Secondary endpoints included changes in biomarkers associated with glucose homeostasis and muscle health., Results: Median age (years) at cancer diagnosis was 16.5 (range, 1.5-21.5) and 35.5 (range, 18.0-67.0) at study enrollment. Enrollment rate was 87%, and 85% of participants completed baseline and end-of-study assessments. The mean percentage of exercise sessions completed was 86.6%; NR compliance was > 90%. There were no severe adverse events attributable to study interventions. Secondary endpoints were not significantly different between study arms at study completion. Myostatin decrease was observed in participants who completed a higher median number of exercise sessions and was associated with decreased intramuscular adipose tissue and increased lower extremity muscle cross-sectional area., Conclusions: A telehealth exercise intervention ± NR supplementation was feasible in CCS with prediabetes. Future studies in larger cohorts may be needed to evaluate their beneficial effects on muscle health and DM risk among CCS., (© 2024 Wiley Periodicals LLC.)

Background: Carvedilol improves cardiac function in patients with heart failure but remains untested as cardioprotective therapy in long-term childhood cancer survivors (ie, those who have completed treatment for childhood cancer and are in remission) at risk for heart failure due to high-dose anthracycline exposure. We aimed to evaluate the activity and safety of low-dose carvedilol for heart failure risk reduction in childhood cancer survivors at highest risk for heart failure., Methods: PREVENT-HF was a randomised, double-blind, phase 2b trial done at 30 hospitals in the USA and Canada. Patients were eligible if they had any cancer diagnosis that resulted in at least 250 mg/m 2 cumulative exposure to anthracycline by age 21 years; completed their cancer treatment at least 2 years previously; an ejection fraction of at least 50% or fractional shortening of at least 25%, or both; and bodyweight of at least 40 kg. Patients were randomly assigned (1:1) with automated computer-generated permuted block randomisation (block size of 4), stratified by age at diagnosis, time since diagnosis, and history of chest-directed radiotherapy, to carvedilol (up-titrated from 3·125 g per day to 12·5 mg per day) or placebo orally for 2 years. Participants, staff, and investigators were masked to study group allocation. The primary endpoint was to establish the effect of carvedilol on standardised left ventricular wall thickness-dimension ratio Z score (LVWT/Dz). Treatment effects were analysed with a linear mixed-effects model for normally distributed data with a linear time effect and testing the significance of treatment*time interaction in the modified intention-to-treat (mITT) cohort (ie, all randomly assigned participants who had a baseline and at least one subsequent echocardiogram measurement). Safety was assessed in the ITT population (ie, all randomly assigned participants). This trial was registered with ClinicalTrials.gov, NCT027175073, and enrolment and follow-up are complete., Findings: Between July 3, 2012, and June 22, 2020, 196 participants were enrolled, of whom 182 (93%) were eligible and randomly assigned to either carvedilol (n=89) or placebo (n=93; ITT population). Median age was 24·7 years (IQR 19·6-36·6), 91 (50%) participants were female, 91 (50%) were male, and 119 (65%) were non-Hispanic White. As of data cutoff (June 10, 2022), median follow-up was 725 days (IQR 378-730). 151 (n=75 in the carvedilol group and n=76 in the placebo group) of 182 participants were included in the mITT population, among whom LVWT/Dz was similar between the two groups (-0·14 [95% CI -0·43 to 0·16] in the carvedilol group vs -0·45 [-0·77 to -0·13] in the placebo group; difference 0·31 [95% CI -0·10 to 0·73]; p=0·14). Two (2%) of 89 patients in the carvedilol group two adverse events of grade 2 or higher (n=1 shortness of breath and n=1 arthralgia) and none in the placebo group. There were no adverse events of grade 3 or higher and no deaths., Interpretation: Low-dose carvedilol appears to be safe in long-term childhood cancer survivors at risk for heart failure, but did not result in significant improvement of LVWT/Dz compared with placebo. These results do not support the use of carvedilol for secondary heart failure prevention in anthracycline-exposed childhood cancer survivors., Funding: National Cancer Institute, Leukemia & Lymphoma Society, St Baldrick's Foundation, Altschul Foundation, Rally Foundation, American Lebanese Syrian Associated Charities., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 Elsevier Ltd.

Importance: There is a paucity of information on the association between clonal hematopoiesis of indeterminate potential (CHIP) and cardiovascular disease (CVD) in patients with cancer, including those with multiple myeloma (MM) undergoing hematopoietic cell transplant (HCT), a population at high risk of developing CVD after HCT., Objective: To examine the association between CHIP and CVD in patients with MM and to describe modifiers of CVD risk among those with CHIP., Design, Setting, and Participants: This was a retrospective cohort study of patients with MM who underwent HCT between 2010 and 2016 at City of Hope Comprehensive Cancer Center in Duarte, California, and had pre-HCT mobilized peripheral blood stem cell (PBSC) products cryopreserved and accessible for CHIP analyses. The study team performed targeted panel DNA sequencing to detect the presence of CHIP (variant allele frequency 2% or more)., Main Outcomes and Measures: The primary end point was the 5-year cumulative incidence and risk for developing de novo CVD (heart failure, coronary artery disease, or stroke) after HCT., Results: Of 1036 consecutive patients with MM (580 male [56%]; median age, 60.0 years) who underwent a first autologous HCT, 201 patients had at least 1 CHIP variant (19.4%) and 35 patients had 2 or more variants (3.4%). The 5-year incidence of CVD was significantly higher in patients with CHIP (21.1% vs 8.4%; P < .001) compared with those without CHIP; the 5-year incidence among those with 2 or more variants was 25.6%. In the multivariable model, CHIP was associated with increased risk of CVD (hazard ratio [HR], 2.72; 95% CI, 1.70-4.39), as well as of individual outcomes of interest, including heart failure (HR, 4.02; 95% CI, 2.32-6.98), coronary artery disease (HR, 2.22; 95% CI, 1.06-4.63), and stroke (HR, 3.02; 95% CI, 1.07-8.52). Patients who had both CHIP and preexisting hypertension or dyslipidemia were at nearly 7-fold and 4-fold increased risk of CVD, respectively (reference: no CHIP, no hypertension, or dyslipidemia)., Conclusion and Relevance: CHIP was significantly and independently associated with risk of CVD in patients with MM undergoing HCT and may serve as a novel biologically plausible biomarker for CVD in this cohort. Patients with MM and both CHIP and cardiovascular risk factors had an exceptionally high risk of CVD. Additional studies are warranted to determine if cardiovascular preventive measures can reduce CHIP-associated CVD risk.

Background: Tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs) have revolutionized the treatment of metastatic renal cell carcinoma (mRCC). Emerging data suggest that these agents can result in clinically significant cardiotoxicity, compromising the care., Methods: We conducted a prospective longitudinal study to evaluate the incidence of de novo cardiac dysfunction as assessed by echocardiography and blood biomarkers in mRCC patients receiving TKI with or without ICI followed at baseline, 3-month and 6-month. We recruited consecutive newly diagnosed mRCC patients treated at our institution between 2015 and 2018 as well as patients with localized RCC not treated with systemic therapies and healthy control (HC) subjects for comparison., Results: Twenty-eight patients were enrolled in the mRCC group (a mean age of 65.2 ± 7.5 years), 29 patients in the localized RCC group (63.6 ± 8.9 years), and 20 volunteers in the HC group (52.9 ± 9.6 years). At baseline, patients from all three groups had normal cardiac function as measured by left ventricular ejection fraction (LVEF), although patients with mRCC or localized RCC had significantly lower mean LVEF compared to HC (61.9%, 62.4%, and 68.1% respectively). Otherwise, there were no statistically significant changes in echocardiographic parameters or incidence of clinical heart failure from baseline to 6-months in patients with mRCC. Cardiac blood biomarkers including troponin I, brain natriuretic peptide, and galectin-3 remained stable over time., Conclusion: Our findings suggest that contemporary treatment strategies of mRCC at this single institution are well tolerated without clinically meaningful overt declines in cardiac function over time. Further studies are warranted to include a larger number of patients to better assess the overall cardiovascular safety associated with contemporary treatments of mRCC., Competing Interests: Declaration of Competing Interest Al authors declare no conflict of interest., (Copyright © 2023 The Author(s).

Background: Patients undergoing hematopoietic cell transplantation (HCT) are at high risk of chronic health complications, including frailty and physical dysfunction. Conventional exercise programs have been shown to improve frailty in other cancer populations, but these have largely been based out of rehabilitation facilities that may act as geographic and logistical barriers. There is a paucity of information on the feasibility of implementing telehealth exercise interventions in long-term HCT survivors., Methods: We conducted a pilot randomized trial to assess the feasibility of an 8-week telehealth exercise intervention in 20 pre-frail or frail HCT survivors. Participants were randomized to either a telehealth exercise (N = 10) or delayed control (N = 10). We administered a remote physical function assessment at baseline, followed by an 8-week telehealth exercise intervention (30-60 min/session, 3 sessions/week), and post-intervention. The primary endpoint was feasibility as determined by 1) > 70% of participants completing all remote physical functional assessments, and 2) > 70% of participants in the exercise group completing > 70% (17/24) of the prescribed exercise sessions. Exploratory outcomes included changes in gait speed, handgrip strength, and short physical performance battery., Results: The mean [standard deviation] age at study enrollment was 64.7 [9.1] years old. Twelve had undergone allogenic and 8 had undergone autologous HCT at an average of 17 years from study enrollment. Both feasibility criteria were achieved. Nineteen patients (95%) completed all remote study outcome assessments at baseline and post-intervention, and nine participants in the exercise group completed > 70% of prescribed exercise sessions. Overall, no significant group x time interaction was observed on handgrip strength, fatigue, body mass index, and short physical performance battery test (P < 0.05). However, there were significant within-group improvements in four-meter gait speed (+ 13.9%; P = 0.004) and 5-minute gait speed (+ 25.4%; P = 0.04) in the exercise group whereas non-significant changes in four-meter gait speed (-3.8%) and 5-minute gait speed (-5.8%) were observed after 8 weeks., Conclusion: Implementing an 8-week telehealth exercise intervention for long-term HCT survivors was feasible. Our findings set the stage for innovative delivery of supervised exercise intervention that reduces the burden of frailty in HCT survivors as well as other at-risk cancer survivors., Trial Registration: The protocol and informed consent were approved by the institutional IRB (IRB#20731) and registered (ClinicalTrials.gov NCT04968119; date of registration: 20/07/2021)., (© 2023.

A major challenge in communicating health-related information is the involvement of multiple complex systems from the creation of the information to the sources and channels of dispersion to the information users themselves. To date, public health communications approaches have often not adequately accounted for the complexities of these systems to the degree necessary to have maximum impact. The virality of COVID-19 misinformation and disinformation has brought to light the need to consider these system complexities more extensively. Unaided, it is difficult for humans to see and fully understand complex systems. Luckily, there are a range of systems approaches and methods, such as systems mapping and systems modeling, that can help better elucidate complex systems. Using these methods to better characterize the various systems involved in communicating public health-related information can lead to the development of more tailored, precise, and proactive communications. Proceeding in an iterative manner to help design, implement, and adjust such communications strategies can increase impact and leave less opportunity for misinformation and disinformation to spread.

Background: The purpose of this study was to examine the association between baseline skeletal muscle measurements, acute toxicity (immune effector cell-associated neurotoxicity syndrome [ICANS], cytokine release syndrome), and treatment efficacy in patients undergoing CAR T-cell therapy for B-lineage lymphoma., Patients and Methods: Skeletal muscle measurements were obtained from automated CT measurements in 226 consecutive patients who received CAR T-cell therapy between 2015 and 2021. The Kaplan-Meier method was used to examine progression-free survival (PFS) and overall survival (OS) at 1-year. Multivariable regression was used to calculate the hazard ratio (HR) with 95% confidence intervals, adjusted for covariates., Results: The median age of the cohort was 63.1 years (range, 18.5-82.4 years), and most patients were male (66%) and had primary refractory disease (58%). Patients with abnormally low skeletal muscle at baseline were at greater risk of ICANS (HR, 1.74; 95% CI, 1.05-2.87) and had longer length of hospitalization (mean 27.7 vs 22.9 days; P<.05) compared with those with normal muscle mass. Abnormal skeletal muscle was independently associated with risk of disease progression (HR, 1.70; 95% CI, 1.11-2.57) and worse survival (HR, 2.44; 95% CI, 1.49-4.00) at 1 year compared with normal skeletal muscle. Individuals who had abnormal skeletal muscle and high lactate dehydrogenase (LDH) levels at baseline had poor 1-year PFS (17%) and OS (12%) compared with those with normal skeletal muscle and LDH levels (72% and 82%, respectively; P<.001). Patients who had abnormal skeletal muscle and LDH levels had a 5-fold risk (HR, 5.34; 95% CI, 2.97-9.62) of disease progression and a 10-fold risk (HR, 9.73; 95% CI, 4.81-19.70) of death (reference: normal skeletal muscle, normal LDH), independent of prior lines of therapy, extent of residual disease at time of CAR T-cell therapy, functional status, or product., Conclusions: This information can be used for risk stratification prior to CAR T-cell therapy or to implement prehabilitation and nutritional optimization before lymphodepletion as well as thereafter. These efforts will be complementary to ongoing efforts toward sustained efficacy after CAR T-cell therapy.

Background: Medical improvisation is an innovative approach to train healthcare professionals in effective communication. The success of this type of training depends on the active engagement of participants., Method: A total of 136 interprofessional healthcare workers completed surveys before and after a two-hour medical improvisation communication training session in October 2020. We investigated individual- and program-level contributors to participation outputs (e.g. engagement and experience)., Results: 97% of healthcare professionals in the participating department took part in the training. 82% described the training in positive terms or as a learning experience. Younger participants, medical doctors, and those who had difficulty tolerating uncertainty were less excited than others about training. Their engagement was associated with their excitement and group size. Uncertainty tolerance predicted engagement via a full mediation of excitement., Conclusions: Building excitement, reducing uncertainty about training, and capping group size are likely to improve participant's engagement and experience and will inform dissemination and implementation efforts.

Background: Advances in autologous hematopoietic stem cell transplantation (HSCT) and supportive care have led to marked improvements in survival for patients with multiple myeloma. Despite these improvements, patients with multiple myeloma remain at high risk of physical dysfunction and frailty due to HSCT and its associated exposures. Although traditional supervised exercise programs can improve frailty in cancer patients and survivors, rehabilitation facilities are typically far from a patient's residence, are offered on fixed days/hours, contain uniform activities for everyone, and carry a higher risk of contact cross-infection due to immunosuppression, which can be barriers to exercise participation. Innovative personalized interventions are needed to overcome the limitations of traditional exercise interventions. The purpose of this study is to determine the efficacy and sustainability of a telehealth exercise intervention on physical function and frailty in patients with multiple myeloma treated with HSCT., Methods: This randomized controlled trial will assess the efficacy of an 8-week telehealth exercise intervention in 60 patients with multiple myeloma who underwent autologous HSCT (30-180 days post-transplant) and are pre-frail or frail. There will be 30 intervention participants and 30 delayed controls. We will administer remote baseline assessments (week 0), followed by an 8-week telehealth intervention (week 1-8), post assessment (week 9), and an additional follow-up assessment (week 17). Our primary endpoint will be improved physical function, as assessed by the Short Physical Performance Battery test. Our secondary endpoint will be a decrease in frailty characteristics such as gait speed, strength, and fatigue. We will also evaluate the sustainability of improved physical function and frailty at week 17. Participants randomized to the intervention group will perform at least 90 min of exercise per week throughout the 8 weeks., Discussion: This study will help optimize the delivery of safe, low-cost, and scalable telehealth exercise interventions to improve health outcomes in patients with multiple myeloma, an understudied population at high risk for physical dysfunction and frailty. Our study may provide the foundation for sustainable telehealth exercise interventions to improve physical function and frailty for other hematologic cancer patients (e.g., acute leukemia, lymphoma) as well as any other cancer population of interest., Trial Registration: ClinicalTrials.gov NCT05142371 . This study was retrospectively registered on December 2nd, 2021, and is currently open to accrual., (© 2022. The Author(s).)

Background: Advances in hematopoietic cell transplantation (HCT) have led to marked improvements in survival. However, adolescents and young adults (AYAs) who undergo HCT are at high risk of developing sarcopenia (loss of skeletal muscle mass) due to the impact of HCT-related exposures on the developing musculoskeletal system. HCT survivors who have sarcopenia also have excess lifetime risk of non-relapse mortality. Therefore, interventions that increase skeletal muscle mass, metabolism, strength, and function are needed to improve health in AYA HCT survivors. Skeletal muscle is highly reliant on mitochondrial energy production, as reflected by oxidative phosphorylation (OXPHOS) capacity. Exercise is one approach to target skeletal muscle mitochondrial OXPHOS, and in turn improve muscle function and strength. Another approach is to use "exercise enhancers", such as nicotinamide riboside (NR), a safe and well-tolerated precursor of nicotinamide adenine dinucleotide (NAD + ), a cofactor that in turn impacts muscle energy production. Interventions combining exercise with exercise enhancers like NR hold promise, but have not yet been rigorously tested in AYA HCT survivors., Methods/design: We will perform a randomized controlled trial testing 16 weeks of in-home aerobic and resistance exercise and NR in AYA HCT survivors, with a primary outcome of muscle strength via dynamometry and a key secondary outcome of cardiovascular fitness via cardiopulmonary exercise testing. We will also test the effects of these interventions on i) muscle mass via dual energy x-ray absorptiometry; ii) muscle mitochondrial OXPHOS via an innovative non-invasive MRI-based technique, and iii) circulating correlates of NAD + metabolism via metabolomics. Eighty AYAs (ages 15-30y) will be recruited 6-24 months post-HCT and randomized to 1 of 4 arms: exercise + NR, exercise alone, NR alone, or control. Outcomes will be collected at baseline and after the 16-week intervention., Discussion: We expect that exercise with NR will produce larger changes than exercise alone in key outcomes, and that changes will be mediated by increases in muscle OXPHOS. We will apply the insights gained from this trial to develop individualized, evidence-supported precision initiatives that will reduce chronic disease burden in high-risk cancer survivors., Trial Registration: ClinicalTrials.gov, NCT05194397.

Background: Childhood cancer survivors (CCS) have increased risk of developing chronic health conditions, including musculoskeletal disorders. Little is known regarding vitamin D deficiency (VDD, <20 ng/ml) and its association with bone mineral density (BMD) in long-term CCS. We evaluated the prevalence and risk factors for VDD in a large, diverse population of long-term CCS, and examined the association between VDD and BMD in patients who underwent guideline-recommended dual-energy X-ray absorptiometry (DXA) screening., Methods: This cross-sectional study included 446 consecutive CCS seen from March 2018 to September 2020. Univariate analyses examined associations between CCS demographics, socioeconomic status, and treatment exposures and VDD. Multivariable logistic regressions identified factors associated with odds of VDD and reduced BMD., Results: Median age at evaluation was 27.5 years (range 7-67 years); median time from completing therapy was 14.2 years (range 2-65 years). Fifty percent were female, and 45% were Hispanic. Twenty-four percent had VDD. In multivariable analysis, overweight and obese BMI were associated with VDD (overweight: OR 1.78, 95% CI 1.03-3.07, p = 0.04; obese: OR 2.40, 95% CI 1.39-4.13, p < 0.01; reference: normal/underweight), as was Hispanic or black race/ethnicity (OR 2.40, 95% CI 1.41-4.09, p < 0.01; reference: non-Hispanic white). In the 118 CCS with DXA results, VDD was independently associated with reduced BMD (OR 3.58, 95%CI 1.33-9.59, p = 0.01)., Conclusions: CCS have a high prevalence of VDD. High BMI and Hispanic or black race/ethnicity were associated with VDD. Survivors with VDD had a greater than threefold risk of reduced BMD. Risk-based screening may facilitate timely interventions to mitigate VDD and improve BMD in CCS., (© 2021 Wiley Periodicals LLC.)

Background: Adverse cardiac remodeling is an important precursor to anthracycline-related cardiac dysfunction, however conventional remodeling indices are limited. We sought to examine the utility of statistical atlas-derived measures of ventricular shape to improve the identification of adverse anthracycline-related remodeling in childhood cancer survivors., Methods: We analyzed cardiac magnetic resonance imaging from a cross-sectional cohort of 20 childhood cancer survivors who were treated with low (< 250 mg/m 2 [ N  = 10]) or high (≥250 mg/m 2 [ N  = 10]) dose anthracyclines, matched 1:1 by sex and age between dose groups. We reconstructed 3D computational models of left ventricular end-diastolic shape for each subject and assessed the ability of conventional remodeling indices (volume, mass, and mass to volume ratio) vs. shape modes derived from a statistical shape atlas of an asymptomatic reference population to stratify anthracycline-related remodeling. We compared conventional parameters and five atlas-based shape modes: 1) between survivors and the reference population ( N  = 1991) using multivariable linear regression, and 2) within survivors by anthracycline dose (low versus high) using two-sided T-tests, multivariable logistic regression, and receiver operating characteristic curves., Results: Compared with the reference population, survivors had differences in conventional measures (lower volume and mass) and shape modes (corresponding to lower overall size and lower sphericity; all p  < 0.001). Among survivors, differences in a shape mode corresponding to increased basal cavity size and altered mitral annular orientation in the high-dose group were observed ( p  = 0.039). Collectively, atlas-based shape modes in conjunction with conventional measures discriminated survivors who received low vs. high anthracycline dosage (area under the curve [AUC] 0.930, 95% confidence interval 0.816, 1.00) significantly better than conventional measures alone (AUC 0.710, 95% confidence interval 0.473, 0.947; AUC comparison p  = 0.0498)., Conclusions: Compared with a reference population, heart size is smaller in anthracycline-exposed childhood cancer survivors. Atlas-based measures of left ventricular shape may improve the detection of anthracycline dose-related remodeling differences., Competing Interests: Competing interestsA.D.M. and J.H.O. are co-founders of and have an equity interest in Insilicomed, and A.D.M. has an equity interest in Vektor Medical.

Background: Hematopoietic cell transplantation (HCT) is a curative option for a growing number of patients with hematologic diseases and malignancies. However, HCT-related factors, such as total body irradiation used for conditioning, graft-versus-host disease, and prolonged exposure to immunosuppressive therapy, result in very high risk for melanoma and non-melanoma skin cancer (NMSC). In fact, skin cancer is the most common subsequent neoplasm in HCT survivors, tending to develop at a time when survivors' follow-up care has largely transitioned to the primary care setting. The goal of this study is to increase skin cancer screening rates among HCT survivors through patient-directed activation alone or in combination with physician-directed activation. The proposed intervention will identify facilitators of and barriers to risk-based screening in this population and help reduce the burden of cancer-related morbidity after HCT., Methods/design: 720 HCT survivors will be enrolled in this 12-month randomized controlled trial. This study uses a comparative effectiveness design comparing (1) patient activation and education (PAE, N = 360) including text messaging and print materials to encourage and motivate skin examinations; (2) PAE plus primary care physician activation (PAE + Phys, N = 360) adding print materials for the physician on the HCT survivors' increased risk of skin cancer and importance of conducting a full-body skin exam. Patients on the PAE + Phys arm will be further randomized 1:1 to the teledermoscopy (PAE + Phys+TD) adding physician receipt of a portable dermatoscope to upload images of suspect lesions for review by the study dermatologist and an online course with descriptions of dermoscopic images for skin cancers., Discussion: When completed, this study will provide much-needed information regarding strategies to improve skin cancer detection in other high-risk (e.g. radiation-exposed) cancer survivor populations, and to facilitate screening and management of other late effects (e.g. cardiovascular, endocrine) in HCT survivors., Trial Registration: ClinicalTrials.gov, NCT04358276 .

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in hematopoietic cell transplantation (HCT) survivors. In these patients, such risk factors as hypertension, diabetes, obesity, and physical inactivity are important modifiers of CVD risk. However, the period when HCT survivors are at greatest risk of developing these risk factors, and in turn CVD, coincides with a drop in engagement in survivorship care. We examined the feasibility and acceptability of a 4-week remote risk-based monitoring (blood pressure monitor, weight scale, pulse oximeter, glucometer) and management program in 18 (11 allogeneic and 7 autologous) HCT survivors at intermediate-high risk of CVD. The median patient age was 66 years (range, 53 to 74 years), 67% had hypertension, 22% had diabetes, 11% were obese (body mass index ≥30 kg/m 2 ), 56% were at intermediate risk of CVD, and 44% were at high risk of CVD. Weekly compliance with the remote monitoring schedule (≥3 readings/week using all devices) ranged from 72% in week 1 to 83% in weeks 2 to 4. Fifteen participants (83%) generated 86 alerts that were outside the predetermined range of normal; 63 of these readings (73%) normalized without intervention, and 23 (27%) necessitated triage by the study research nurse. Nearly all participants reported that the study kept them motivated and involved in their healthcare, and >85% agreed that the study supported their healthcare goals, helped them learn and manage their health conditions, and increased their access to healthcare. These findings may set the foundation for innovative risk-based and remote interventions to reduce the burden of CVD in this growing population of patients., (Copyright © 2020 American Society for Transplantation and Cellular Therapy.

Purpose: Childhood cancer survivors are at risk for anthracycline-related cardiac dysfunction, often developing at a time when they are least engaged in long-term survivorship care. New paradigms in survivorship care and chronic disease screening are needed in this population. We compared the accuracy of a novel handheld mHealth platform (Vivio) as well as echocardiography for assessment of cardiac function [left ventricular ejection fraction (EF)] in childhood cancer survivors with cardiac magnetic resonance (CMR) imaging (reference). Experimental Design: Cross-sectional study design was used. Concurrent evaluation of EF was performed using Vivio, two-dimensional (2D) echocardiography, and CMR. Differences in mean EF (2D echocardiography vs. CMR; Vivio vs. CMR) were compared using Bland-Altman plots. Linear regression was used to evaluate proportional bias. Results: A total of 191 consecutive survivors participated [50.7% female; median time from diagnosis: 15.8 years (2-44); median anthracycline dose: 225 mg/m 2 (25-642)]. Echocardiography overestimated mean EF by 4.9% ( P < 0.001); linear regression analysis confirmed a proportional bias, when compared with CMR ( t = 3.1, P < 0.001). There was no difference between mean EF derived from Vivio and from CMR (-0.2%, P = 0.68). The detection of cardiac dysfunction via echocardiography was poor when compared with CMR [Echo EF < 45% (sensitivity 14.3%), Echo EF < 50% (sensitivity 28.6%)]. Sensitivity was substantially better for Vivio-based measurements [EF < 45% or EF < 50% (sensitivity 85.7%)]. Conclusions: This accessible technology has the potential to change the day-to-day practice of clinicians caring for the large number of patients diagnosed with cardiac dysfunction and heart failure each year, allowing real-time monitoring and management of their disease without the lag-time between imaging and interpretation of results.

Purpose Optimal assessment methods and criteria for reporting hearing outcomes in children who receive treatment with cisplatin are uncertain. The objectives of our study were to compare different ototoxicity classification systems, to evaluate the feasibility of including otoacoustic emissions and extended high frequency audiometry, and to evaluate a central review mechanism for audiologic results for cisplatin-treated children in the cooperative group setting. Patients and Methods Eligible participants were 1 to 30 years, with planned cisplatin-containing treatment. Hearing evaluations were conducted at baseline, before each cisplatin cycle, and at the end of therapy. Audiologic results were assessed and graded by the testing audiologist and by two central review audiologists using the American Speech-Language-Hearing Association Ototoxicity Criteria (ASHA), Common Terminology Criteria for Adverse Events, version 3.0 (CTCAE), and Brock Ototoxicity Grades (Brock). One central reviewer also used the International Society of Pediatric Oncology Ototoxicity Scale (SIOP). Results At the end of treatment, the prevalence of any degree of ototoxicity ranged from 40% to 56%, and severe ototoxicity ranged from 7% to 22%. Compared with CTCAE, SIOP detected significantly more ototoxicity ( P = .004), whereas Brock criteria detected significantly fewer patients with any or severe ototoxicity ( P < .001 for both). SIOP detected ototoxicity earlier than did the other scales. Agreement between the central reviewers and the institutional audiologist was almost perfect for ASHA and Brock, whereas the poorest agreement occurred with CTCAE. Conclusion The SIOP scale may be superior to ASHA, Brock, and CTCAE scales for classifying ototoxicity in pediatric patients who were treated with cisplatin. Future studies should evaluate inter-rater reliability of the SIOP scale.

Background: Anthracyclines are widely used in the treatment of childhood cancer. One of the well-recognized side-effects of anthracycline therapy is dose-dependent cardiomyopathy that may progress to heart failure (HF) years after completion of cancer-directed therapy. This study will evaluate the efficacy of low-dose beta-blocker (carvedilol) for HF risk reduction in childhood cancer survivors at highest risk for HF. The proposed intervention has the potential to significantly reduce chronic cardiac injury via interruption of neurohormonal systems responsible for left ventricular (LV) remodeling, resulting in improved cardiac function and decreased risk of HF. The intervention is informed by previous studies demonstrating efficacy in pediatric and adult non-oncology populations, yet remains unstudied in the pediatric oncology population., Methods/design: The primary objective of the trial is to determine impact of the intervention on echocardiographic markers of cardiac remodeling and HF risk, including: LV wall thickness/ dimension ratio (LVWT/D; primary endpoint), as well as LV ejection fraction, volume, and blood biomarkers (natriuretic peptides, galectin-3) associated with HF risk. Secondary objectives are to establish safety and tolerability of the 2-year course of carvedilol using: 1) objective measures: hepatic and cardiovascular toxicity, treatment adherence, and 2) subjective measures: participant self-reported outcomes. Two hundred and fifty survivors of childhood cancer (diagnosed <21 years of age), and previously treated with high-dose (≥300 mg/m 2 ) anthracyclines will be enrolled in a randomized, double-blind, placebo controlled trial. After baseline assessments, participants will be randomized in a 1:1 ratio to low-dose carvedilol (maximum dose: 12.5 mg/day) or placebo. Carvedilol or placebo is up-titrated (starting dose: 3.125 mg/day) according to tolerability., Discussion: When completed, this study will provide much-needed information regarding a physiologically plausible pharmacological risk-reduction strategy for childhood cancer survivors at high risk for developing anthracycline-related HF., Trial Registration: ClinicalTrials.gov; NCT02717507.
