Exercise interventions for patients with pediatric cancer during inpatient acute care: A systematic review of literature

Physical inactivity has been shown to exacerbate negative side effects experienced by pediatric patients undergoing cancer therapy. Exercise interventions are being created in response. This review summarizes current exercise intervention data in the inpatient pediatric oncology setting. Two independent reviewers collected literature from three databases, and analyzed data following the PRISMA statement for systematic reviews and meta‐analyses. Ten studies were included, representing 204 patients. Good adherence, positive trends in health status, and no adverse events were noted. Common strategies included individual, supervised, combination training with adaptability to meet fluctuating patient abilities. We recommend that general physical activity programming be offered to pediatric oncology inpatients.     

A systematic review of models of care for the follow‐up of childhood cancer survivors

Follow‐up care for survivors of childhood cancer is increasingly seen as a priority service as numbers of survivors increase. Despite this there are few published evaluations of the available options. We conducted a systematic review of published and unpublished literature. Seven uncontrolled studies, and one comparative study of a related intervention, were identified. Observational data suggest that follow‐up care was useful even for patients who did not perceive this as a need. Suitably powered, well‐conducted, controlled trials of adequate duration that directly compare follow‐up models are required to provide robust evidence on the optimal care for these patients.

Nonneutropenic fever in children with cancer: A scoping review of management and outcome

To date, very few studies have addressed nonneutropenic fever (NNF) in children with cancer, and there are no consensus guidelines. This scoping review aims to describe the rate of bacteremia, risk factors for infection and management, and outcomes of NNF in this population. Across 15 studies (n = 4106 episodes), the pooled‐average bacteremia rate was 8.2%, and risk factors included tunneled external central venous catheter, clinical instability, and higher temperature. In two studies, antibiotics were successfully withheld in a subset of low‐risk patients. Overall outcomes of NNF appear favorable; however, further research is required to determine its true clinical and economic impact.     

Lifestyle behavior interventions delivered using technology in childhood,adolescent, and young adult cancer survivors: A systematic review

Childhood, adolescent, and young adult cancer survivors demonstrate increased cardio‐metabolic risk factors, which are amenable to lifestyle changes. The use of technology to impact lifestyle change expands previously limited intervention access, yet little is known about its use. We summarized lifestyle interventions for survivors delivered using technology, finding six studies, primarily targeting physical activity. Study samples were small and durations ranged from 5 to 16 weeks and outcomes modest. Participants were older, white, survivors of leukemia or brain tumors, and the majority received Web‐based interventions. Study quality was moderate. Few technology‐based interventions have been developed, suggesting an area of opportunity for survivors.     

Cesarean delivery in low- and middle-income countries: A review of quality of care metrics and targets for improvement

Improving quality of care in low-and middle-income countries (LMICs) is a global priority, specifically around maternal and newborn care, where mortality and morbidity remain unacceptably high. Cesarean delivery is the most common procedure in women, thus evaluating quality around the provision of this intervention provides insight into overall quality of care around childbirth. In this review we provide an overview on the quality of care around cesarean delivery using the six domains of quality proposed by the Institute of Medicine: equity, effectiveness, efficiency, safety, timeliness and patient-centered care. We review evidence of potential quality gaps in each of these domains around cesarean delivery in LMICs, discuss opportunities for improvement and provide suggestions on metrics for tracking quality in each of these domains. As cesarean delivery rates increase globally, efforts to ensure quality will be essential to drive continued and sustained improvements in global maternal and newborn outcomes.     

Impact of undernutrition on the pharmacokinetics of chemotherapy in children with cancer: A systematic review

Objectives

This systematic review provides an overview of the effect of undernutrition on the pharmacokinetics of chemotherapy in children with cancer.

Methods

PubMed, Embase, and Cochrane were searched to identify eligible studies. This study uses the definition for undernutrition from the World Health Organization and the Gomez classification.

Results

Four studies with a total of 668 children with cancer were included and n = 121 (18%) were undernourished. Significant decreased clearance rates were found for vincristine in undernourished children compared to children with a normal nutritional status.

Conclusion

Presenting outcomes only show significant changes in the pharmacokinetics of vincristine in undernourished children with cancer. However, data are scarce, groups were small, and none of the studies included severely undernourished children. In order to improve outcomes for (severely) undernourished children with cancer, more pharmacokinetic research is needed. The ultimate goal would be to develop subgroups, and ultimately individualized drug dosing in order to improve outcomes for children with cancer worldwide.     

Patterns in child stunting by age: A cross-sectional study of 94 low- and middle-income countries

Child stunting prevalence is primarily used as an indicator of impeded physical growth due to undernutrition and infections, which also increases the risk of mortality, morbidity and cognitive problems, particularly when occurring during the 1000 days from conception to age 2 years. This paper estimated the relationship between stunting prevalence and age for children 0–59 months old in 94 low- and middle-income countries. The overall stunting prevalence was 32%. We found higher stunting prevalence among older children until around 28 months of age—presumably from longer exposure times and accumulation of adverse exposures to undernutrition and infections. In most countries, the stunting prevalence was lower for older children after around 28 months—presumably mostly due to further adverse exposures being less detrimental for older children, and catch-up growth. The age for which stunting prevalence was the highest was fairly consistent across countries. Stunting prevalence and gradient of the rise in stunting prevalence by age varied across world regions, countries, living standards and sex. Poorer countries and households had a higher prevalence at all ages and a sharper positive age gradient before age 2. Boys had higher stunting prevalence but had peak stunting prevalence at lower ages than girls. Stunting prevalence was similar for boys and girls after around age 45 months. These results suggest that programmes to prevent undernutrition and infections should focus on younger children to optimise impact in reducing stunting prevalence. Importantly, however, since some catch-up growth may be achieved after age 2, screening around this time can be beneficial.     

Interdisciplinary care of pediatric oncology patients: A survey of clinicians in Central America and the Caribbean

Background

Quality cancer care depends on interdisciplinary communication. This study explored the communication practices of interdisciplinary clinicians, the types of healthcare services for which they engage in interdisciplinary collaboration, and the association between interdisciplinary care and perceived quality of care, as well as job satisfaction.

Methods

We conducted a survey of interdisciplinary clinicians from cancer centers in Guatemala, Honduras, Panama, El Salvador, and Haiti. The survey included 68 items including previously validated tools and novel questions.

Results

Total 174 interdisciplinary clinicians completed the survey: nurses (n = 60), medical subspecialists (n = 35), oncologists (n = 22), psychosocial providers (n = 20), surgeons (n = 12), pathologists (n = 9), radiologists (n = 9), and radiation oncologists (n = 5). Oncologists reported daily communication with nurses (95%) and other oncologists (91%). While 90% of nurses reported daily communication with other nurses, only 66% reported daily communication with oncologists, and more than 50% of nurses reported never talking to pathologists, radiologists, radiation oncologists, or surgeons. Most clinicians described interdisciplinary establishment of cancer treatment goals and prognosis (84%), patient preferences (81%), and determination of first treatment modality (80%). Clinicians who described more interdisciplinary collaboration had higher job satisfaction (p = .04) and perceived a higher level of overall quality of care (p = .004).

Conclusions

Clinicians in these limited resource settings describe strong interdisciplinary collaboration contributing to higher job satisfaction and perceived quality of care. However, nurses in these settings reported more limited interdisciplinary communication and care. Additional studies are necessary to further define clinical roles on interdisciplinary care teams and their associations with patient outcomes.     

Traditional and complementary medicine used with curative intent in childhood cancer: A systematic review

Traditional and complementary medicine (T&CM) strategies are widely utilized in pediatric oncology, with many families reporting T&CM use with the intention to cure cancer. Study of T&CM agents presents many challenges, as a heterogeneous group of agents and techniques are used for a variety of different purpose in many different oncologic conditions. We present a systematic review of the literature examining published reports in which T&CM agents are used with an intention of cure. Twenty‐two reports were identified, with most reports being of poor quality. Novel paradigms are likely needed to further investigate T&CM agents.     

Identifying opportunities to bridge disparity gaps in curing childhood cancer in Malawi: Malignancies with excellent curative potential account for the majority of diagnoses

The majority of African children with cancer die without access to resources. We describe efforts to build a public treatment program with curative intent for childhood cancer in Lilongwe, Malawi despite severe limitations in diagnostic and therapeutic resources. We retrospectively analyzed a cohort of childhood cancer patients at Kamuzu Central Hospital from 12/2011–6/2013. Consistently available chemotherapeutic agents were limited to cyclophosphamide, vincristine, doxorubicin, bleomycin, methotrexate, and prednisone. Of 258 newly diagnosed childhood malignancies, 17 patients with retinoblastoma were excluded from clinical analyses due to insufficient clinical data. Among the remainder of the cohort (n = 241), 42% were female with median age 8.4 years (range 0.6–17.9). Forty-six (19%) were HIV-infected (42 Kaposi sarcoma, 3 Burkitt lymphoma, 1 Hodgkin lymphoma). The most common clinical presentations were palpable abdominal mass (41%), peripheral lymphadenopathy (33%), and jaw mass (17%). Nearly two-thirds of total diagnoses were accounted for by Burkitt lymphoma (n = 74), Kaposi sarcoma (n = 52), Hodgkin lymphoma (n = 21), and Wilms tumor (n = 19). Twelve-month overall survival for these 4 most common diagnoses was 54% (95% confidence interval 46–61) versus 19% (95% confidence interval 11–30) for all other diagnoses (median follow-up 19 months). Treatment-related mortality was highest in patients with non-Wilms solid tumors of the abdomen (48% versus 10% for the overall cohort, p < 0.001), while treatment abandonment was highest in patients with bone and soft-tissue sarcomas (29% versus 14% overall, p = 0.05). Childhood cancers with excellent curative potential accounted for the majority of patients, establishing an opportunity to build treatment programs with curative intent despite severe limitations.     

Impact of COVID-19 pandemic on delivery of pediatric radiotherapy: A critical review

The COVID-19 pandemic has prevented the timely diagnosis and treatment of many diseases, including pediatric cancer. Its impact on pediatric oncologic treatments warrants investigation. As radiotherapy is an integral component of cancer care, we reviewed the published data regarding the impact of COVID-19 on the delivery of pediatric radiotherapy to inform actions for future global events. We found that disruptions in radiotherapy were reported amongst interruptions in other therapies. Disruptions were more common in low-income countries (78%) and low middle-income countries (68%) compared with upper middle-income countries (46%) and high-income countries (10%). Several papers included recommendations for mitigation strategies. Altered treatment regimens were common, including increasing the use of active surveillance and systemic therapy to delay local therapies, and accelerated/hypofractionated dose delivery. Our findings suggest that COVID-19 has impacted radiotherapy delivery in the pediatric population globally. Countries with limited resources may be more affected. Various mitigation strategies have been developed. The efficacy of mitigation measures warrants further investigation.
