Regional practice norms for the care of childhood cancer survivors at risk for cardiomyopathy: A Delphi study.

BACKGROUND: Treatment-associated cardiomyopathy is a leading cause of morbidity and mortality for childhood cancer survivors (CCS). As evidence is not available to guide the management of CCS at risk for cardiomyopathy, we aim to describe the collective opinion of regional experts for the care of these patients using a consensus-based Delphi methodology. PROCEDURE: Nineteen physicians from the New England region who care for CCS treated with cardiotoxic therapy (anthracyclines, thoracic radiation) participated in a Delphi panel querying their management approach, using three rounds of anonymous questionnaires formatted as five clinical scenarios. Consensus ≥ 89% agreement. RESULTS: The response rate was 100% for the first round and 95% for subsequent rounds. Panelists reached consensus on screening asymptomatic CCS with serial echocardiograms (94%) and electrocardiograms (89%), with some disagreement on frequency during pregnancy (83%). All panelists agreed with exercise promotion, with no restrictions on weight training. Consensus was reached on indications for referrals; cardiology for asymptomatic left ventricular dysfunction (ALVD) (100%) and maternal-fetal medicine for pregnancy (94%). In the scenario of ALVD, there was disagreement on the benefit of additional cardiac testing (50% cardiologists recommended cardiac MRI), and although all panelists endorsed treating with angiotension-converting enzyme (ACE) inhibitors, most adult cardiologists (75%) also recommended therapy with beta blockers, compared with none of the pediatric cardiologists or primary-care physicians. CONCLUSIONS: Despite a lack of evidence to guide the management of CCS at risk for cardiomyopathy, a panel of regional physicians reached consensus on managing most clinical scenarios. A controversial area requiring further study is the medical management of ALVD.

Barriers and facilitators to sexual and reproductive health communication between pediatric oncology clinicians and adolescent and young adult patients: The clinician perspective.

BACKGROUND: Sexual and reproductive health (SRH) is identified by adolescent and young adult (AYA) patients with cancer as an important but often neglected aspect of their comprehensive cancer care. The purpose of this study was to investigate the attitudes and perceptions of pediatric oncology clinicians towards discussing SRH with AYAs, and to understand perceived barriers to effective communication in current practice. PROCEDURE: Pediatric oncology clinicians (physicians, certified nurse practitioners, and physician assistants) participated in semi-structured qualitative interviews investigating attitudes about SRH communication with AYAs and barriers to such conversations. Twenty-two clinicians participated from seven institutions in the Northeastern United States. Interviews were audio-recorded, transcribed, and coded using a thematic analysis approach. RESULTS: Interviews with pediatric oncology clinicians revealed the following five primary themes: the role for pediatric oncology clinicians to discuss SRH, the focus of current SRH conversations on fertility, the meaning of "sexual health" as safe sex and contraception only, clinician-reported barriers to SRH conversations, and the need for education and support. Communication barriers included lack of knowledge/experience, lack of resources/referrals, low priority, parents/family, patient discomfort, clinician discomfort, time, and lack of rapport. Clinicians identified resource and support needs, including formal education and SRH education materials for patients and families. CONCLUSIONS: Although the study participants identified a role for pediatric oncology clinicians in SRH care for AYA patients with cancer, multiple barriers interfere with such discussions taking place on a regular basis. Future efforts must focus on resource development and provider education and training in SRH to optimize the care provided to this unique patient population.

End-of-life care in the neonatal intensive care unit: experiences of staff and parents.

OBJECTIVE: The aim of the study is to determine the perceptions of end-of-life care practices and experience with infants who have died in the NICU among neonatologists, advanced practitioners, nurses, and parents, and also to determine perceived areas for improvement and the perceived value of a palliative care team. STUDY DESIGN: This descriptive, exploratory cross-sectional study using surveys consisting of 7-point Likert scales and free response comments was sent to all neonatologists (n = 14), advanced practitioners (n = 40), and nurses (n = 184) at Connecticut Children's Medical Center's neonatal intensive care units (NICUs) in April 2013 and to all parents whose infants died in these NICUs from July 1, 2011, to December 31, 2012 (n = 28). RESULTS: The response rates were 64.3% for physicians; 50.0% for practitioners; 40.8% for nurses; and 30.4% for parents. Most providers reported they feel comfortable delivering end-of-life care. Bereavement support, debriefing/closure conferences, and education did not occur routinely. Families stressed the importance of memory making and bereavement/follow-up. Consistent themes of free responses include modalities for improving end-of-life care, inconsistency of care delivery among providers, and the importance of memory making and follow-up. CONCLUSION: End-of-life experiences in the NICU were perceived as variable and end-of-life practices were, at times, perceived as inconsistent among providers. There are areas for improvement, and participants reported that a formalized palliative care team could help. Families desire memory making, follow-up, and bereavement support.

Development of a Primary Care-Based Clinic to Support Adults With a History of Childhood Cancer: The Tactic Clinic.

PURPOSE: Describe the development and evolution of a primary-care-based, multidisciplinary clinic to support the ongoing care of adult survivors of childhood cancer. METHODS: A consultative clinic for adult survivors of childhood cancer has been developed that is located in an adult, academic internal medicine setting and is based on a long-term follow-up clinic model available at Children's Hospital Colorado. RESULTS: The clinic opened in July 2008. One hundred thirty-five patients have been seen as of April 2014. Referrals and clinic capacity have gradually increased over time, and a template has been developed in the electronic medical record to help facilitate completion of individualized care plan letters. CONCLUSIONS: A primary care-based, multidisciplinary consultative clinic for adults with a history of childhood cancer survivor is feasible and actively engages adult primary care resources to provide risk-based care for long-term pediatric cancer survivors. This model of care planning can help support adult survivors of pediatric cancer and their primary care providers in non-academic, community settings as well.

The potential of micro- and nanoplastics to exacerbate the health impacts and global burden of non-communicable diseases.

Non-communicable diseases (NCD) constitute one of the highest burdens of disease globally and are associated with inflammatory responses in target organs. There is increasing evidence of significant human exposure to micro- and nanoplastics (MnPs). This review of environmental MnP exposure and health impacts indicates that MnP particles, directly and indirectly through their leachates, may exacerbate inflammation. Meanwhile, persistent inflammation associated with NCDs in gastrointestinal and respiratory systems potentially increases MnP uptake, thus influencing MnP access to distal organs. Consequently, a future increase in MnP exposure potentially augments the risk and severity of NCDs. There is a critical need for an integrated one-health approach to human health and environmental research for assessing the drivers of human MnP exposure and their bidirectional links with NCDs. Assessing these risks requires interdisciplinary efforts to identify and link drivers of environmental MnP exposure and organismal uptake to studies of impacted disease mechanisms and health outcomes.

Follicular Dendritic Cell Sarcoma in a Patient With Adolescent-Onset Crohn's Disease Exposed to Multiple Immunomodulator and Biologic Therapies.

Children and adolescents with inflammatory bowel disease are often treated with immunomodulators (thiopurines, methotrexate) and biologics (anti-TNF, anti-integrin) for extended periods despite concerns about long-term safety. Here, we report a case of follicular dendritic cell sarcoma, a very rare malignancy, and the first reported presentation in a patient with inflammatory bowel disease exposed to infliximab, methotrexate, and vedolizumab. We review the key clinical features and diagnostic factors of this malignancy. The pathogenesis of follicular dendritic cell sarcoma is largely unknown, however, knock out of B-cell TNF in mice has been related to follicular dendritic cell dysregulation through its impact on NF-κB pathways and CXCL13 chemokines. It is unknown whether any relationship exists between this patient's diagnosis of Crohn's disease and therapeutic exposures to this rare malignancy. We document this case in the literature to raise awareness among other clinicians who may observe a similar case.

Delphi Panel Consensus Recommendations for Screening and Managing Childhood Cancer Survivors at Risk for Cardiomyopathy.

Background: Cardiomyopathy is a leading cause of late morbidity and mortality in childhood cancer survivors (CCS). Evidence-based guidelines recommend risk-stratified screening for cardiomyopathy, but the management approach for abnormalities detected when screening asymptomatic young adult CCS is poorly defined. Objectives: The aims of this study were to build upon existing guidelines by describing the expert consensus-based cardiomyopathy screening practices, management approach, and clinical rationale for the management of young adult CCS with screening-detected abnormalities and to identify areas of controversy in practice. Methods: A multispecialty Delphi panel of 40 physicians with expertise in cancer survivorship completed 3 iterative rounds of semi-open-ended questionnaires regarding their approaches to the management of asymptomatic young adult CCS at risk for cardiomyopathy (screening practices, referrals, cardiac testing, laboratory studies, medications). Consensus was defined as ≥90% panelist agreement with recommendation. Results: The response rate was 100% for all 3 rounds. Panelists reached consensus on the timing and frequency of echocardiographic screening for anthracycline-associated cardiomyopathy, monitoring during pregnancy, laboratory testing for modifiable cardiac risk factors, and referral to cardiology for ejection fraction ≤50% or preserved ejection fraction with diastolic dysfunction. Controversial areas (<75% agreement) included chest radiation dose threshold to merit screening, indications for advanced cardiac imaging and cardiac serum biomarkers for follow-up of abnormal echocardiographic findings, and medical management of asymptomatic left ventricular systolic dysfunction. Conclusions: Expert practice is largely consistent with existing risk-based screening guidelines. Some recommendations for managing abnormalities detected on screening echocardiography remain controversial. The rationale offered by experts for divergent approaches may help guide clinical decisions in the absence of guidelines specific to young adult CCS.

Filling in the knowledge gap: Observing MacroPlastic litter in South Africa's rivers.

Only 12% of the world's published plastic research includes references to Africa despite it being a significant contributor to the global plastic waste and mismanagement problem (~88.5% of Africa's plastic waste is mismanaged). Ocean plastics are transported from land by rivers to the sea. However, source contextualization is complex. Many African rivers predominantly run alongside human settlements that host informal waste dumpsites. In this study a simple cost effective, easily deployed, consistent and replicable survey methodology was employed. The study quantified macroplastic in three rivers discharging into Algoa Bay, South Africa. The results indicated that industrial Swartkops and metropolitan Baakens Rivers both illustrate moderate plastic pollution (>3000 plastic particles/day), with the relatively natural Sundays River to showing minimal evidence of river macro plastic (<100 plastic particles/day). The types of plastic were noted using the RIMMEL app (premier African implementation), enabling proportional comparison of different plastic litter types to be completed.

Examination of the ocean as a source for atmospheric microplastics.

Global plastic litter pollution has been increasing alongside demand since plastic products gained commercial popularity in the 1930's. Current plastic pollutant research has generally assumed that once plastics enter the ocean they are there to stay, retained permanently within the ocean currents, biota or sediment until eventual deposition on the sea floor or become washed up onto the beach. In contrast to this, we suggest it appears that some plastic particles could be leaving the sea and entering the atmosphere along with sea salt, bacteria, virus' and algae. This occurs via the process of bubble burst ejection and wave action, for example from strong wind or sea state turbulence. In this manuscript we review evidence from the existing literature which is relevant to this theory and follow this with a pilot study which analyses microplastics (MP) in sea spray. Here we show first evidence of MP particles, analysed by µRaman, in marine boundary layer air samples on the French Atlantic coast during both onshore (average of 2.9MP/m3) and offshore (average of 9.6MP/m3) winds. Notably, during sampling, the convergence of sea breeze meant our samples were dominated by sea spray, increasing our capacity to sample MPs if they were released from the sea. Our results indicate a potential for MPs to be released from the marine environment into the atmosphere by sea-spray giving a globally extrapolated figure of 136000 ton/yr blowing on shore.

The Patient-Provider Relationship in Adolescent Oncology: AnExploratory Factor Analysis of a Thirteen-Item Self-Report Measure.

PURPOSE: The patient-provider relationship has been understudied in adolescents with cancer. The currentstudy describes an exploratory factor analysis of a patient-provider relationship self-report measure developed for use in adolescent oncology. METHODS: A self-report measure was included in an iPad/tablet survey delivered to 102 adolescent cancer patients (diagnosed between the ages of 10 and 20). Principal factor analysis with promax rotation and a three-factor structure was specified. RESULTS: The final solution identified three underlying dimensions of the patient-provider relationship-SupportingIndependence (69.7% variance explained; Cronbach's α = .89), Family-Centered Communication (50.0% variance explained; Cronbach's α = .73), and Respectful Relationships (40.1% variance; Cronbach's α = .66). DISCUSSION: The current measure highlights the unique developmental place of adolescent cancer patients in their preference for aspects of both patient-centered and family-centered care. The current analysis begins to fill the need for adolescent-tailored measurement to assess the patient-provider relationship in this population.

Adolescent cancer patients' perceived quality of cancer care: The roles of patient engagement and supporting independence.

OBJECTIVES: A lack of focus on variation in engagement among cancer populations of differing developmental stages led us to examine the associations between patient engagement, the patient-provider relationship, cognitive development, readiness to transition to adulthood (transitional readiness) and perceived quality of care. METHODS: A sample of 101 adolescent cancer patients (diagnosed 10-20 years) completed survey items concerning patient engagement, dimensions of the patient-provider relationship, cognitive development, transitional readiness, and demographic characteristics using an iPad/tablet during a routine clinic visit. RESULTS: Patient engagement was not significantly associated with perceived quality of care (b = .02, 95% CI: -0.06, 0.11). Instead, adolescents with providers that supported their independence (b = .34, 95% CI: 0.17, 0.52) were significantly more likely to perceive higher quality care. CONCLUSION: Supportive patient-provider relationships are an integral part of adolescents' perceptions of quality of care. Adolescents are still gaining important skills for navigating the medical system, and the patient-provider relationship may provide an important scaffolding relationship to help adolescents build independence in their treatment experience. PRACTICE IMPLICATIONS: Identifying potential mechanisms through which adolescents can provide their opinion, ask questions, and participate in their treatment plan will help in supporting adolescent independence and improve quality of care.

Empiric treatment of multidrug-resistant Burkholderia cepacia lung exacerbation in a patient with cystic fibrosis: application of pharmacodynamic concepts to meropenem therapy.

A 31-year-old man with cystic fibrosis was diagnosed with multidrug-resistant Burkholderia cepacia pneumonia. Meropenem 2000 mg every 8 hours was administered as a 3-hour infusion to maximize pharmacodynamic exposure; oral minocycline 100 mg twice/day was also given. Blood samples were collected to confirm meropenem concentrations. Concentrations above the mimimum inhibitory concentration (MIC) of 8 microg/ml were achieved for 52% of the dosing interval, which is greater than what is required for a bactericidal effect. The patient's condition improved, he was discharged, and completed a 3-week course of the antibiotic regimen. After 6 months, he had remained at his baseline level of health. This case demonstrates that pharmacodynamic principles can be used to design an antibiotic dosing regimen that can achieve optimal exposures when the MIC is above that considered susceptible to conventional dosing strategies.

How confident are young adult cancer survivors in managing their survivorship care? A report from the LIVESTRONG™ Survivorship Center of Excellence Network.

INTRODUCTION: This study examined the association between sociodemographic, cancer treatment, and care delivery factors on young adult cancer survivors' confidence in managing their survivorship care. METHODS: Survivors aged 18-39 years (n = 376) recruited from the LIVESTRONG™ Survivorship Center of Excellence Network sites completed a survey assessing self-reported receipt of survivorship care planning, expectations of their providers, and confidence in managing their survivorship care. Multivariate logistic regression identified characteristics of those reporting low confidence in managing their survivorship care. RESULTS: Mean age was 28 years; mean interval from diagnosis was 9 ± 8 years. Seventy-one percent reported currently attending an oncology survivorship clinic. Regarding survivorship care planning, 33% did not have copies of their cancer-related medical records, 48% did not have a treatment summary, and 55% had not received a survivorship care plan. Seventy percent identified the oncologist as the most important health care provider for decisions regarding test and treatment decisions while 10% reported using a "shared-care model" involving both primary care providers and oncologists. Forty-one percent were classified as having low confidence in managing survivorship care. In multivariate analysis, low confidence was associated with non-white ethnicity and lack of a survivorship care plan (both p < 0.05). DISCUSSION/CONCLUSIONS: Findings suggest that provision of survivorship care plans for young adult cancer survivors can be used to improve confidence in managing survivorship care, particularly for ethnic minorities. IMPLICATIONS FOR CANCER SURVIVORS: Survivors should consider advocating for receipt of a survivorship care plan as it may facilitate confidence as a consumer of survivorship care.
