Indigenous participation in pediatric Indigenous health research in Canada: a systematic review.

For health inequities to be successfully addressed through health research, it is necessary for researchers to strive for genuine engagement with stakeholders. Indigenous people provide critical perspectives in Indigenous health research. The objective of this review was to systematically review the existing pediatric Indigenous health research in Canada to determine the prevalence of Indigenous participation. Embase, MEDLINE, Cochrane Library were searched on April 15, 2017 and updated on July 16, 2020. A total of 798 studies focused on the health of Indigenous children ≤18 in Canada were included, of 17,752 abstracts screened in English and French. A total of 46.1% of articles indicated Indigenous participation, increasing over time. Organization/government was the most common form of Indigenous participation (62.8%) and Indigenous researcher as author was least common (10.9%). Participation by child age, geography and topic area varied. The most common category of topic researched was nutrition, lifestyle and anthropometrics. Indigeneity of researchers was determined by self-identification in the papers and may be an underestimate. Although improving over time, less than half of studies about Indigenous children in Canada included Indigenous participation in their execution. Journals and funding bodies must ensure fulsome participation of Indigenous people in research focused on Indigenous children. IMPACT: Indigenous participation in pediatric Indigenous health research is critical to producing ethical relevant and actionable results. This review describes the status of Indigenous participation in this body of work in Canada. This review highlights areas of concern and strength to improve the practices and ethics of medical researchers in this area, thereby increasing relevance of pediatric Indigenous health research to communities.

Cancer-related fatigue: scoping review to synthesize a definition for childhood cancer survivors.

CONTEXT: There is no universal definition of cancer-related fatigue (CRF) specific to childhood cancer survivors, despite this population facing unique long-term side effects from their cancer. We aimed to synthesize and combine existing definitions of CRF specific to this context to inform on the necessity of a panel of experts to formulate a new definition of CRF for childhood cancer survivors. METHODS: The literature search was performed in various databases. Titles, abstracts, and keywords were screened by two researchers to confirm eligibility. The data extraction process was performed by two researchers. Our search was conducted in various databases. RESULTS: Thirty articles were included in the qualitative analysis. Two coders reached consensus on 14 codes. The thematization process produced 4 themes: frequency, context, attributes, and consequences of CRF. These themes were used to synthesize a definition of CRF, as follows: "In childhood cancer survivors, cancer-related fatigue is a common late effect of cancer and cancer treatments. It is characterized by a subjective, persistent, and multidimensional experience that differs from normal fatigue in the physical, emotional, and/or cognitive spheres. Cancer-related fatigue may have a variety of negative consequences including a reduced quality of life and level of functioning, a lack of vigor, work difficulties, relationship issues, and emotional distress." CONCLUSION: A definition of CRF applicable to childhood cancer survivors is timely to organize research efforts and design appropriate interventions. The proposed definition is a first step towards the formulation of a new definition of CRF specific to childhood cancer survivors by experts.

Contribution of Fatigue to Cognitive Dysfunction in Childhood Acute Lymphoblastic Leukemia Survivors.

Late effects such as neurocognitive issues and fatigue have been reported in childhood acute lymphoblastic leukemia (cALL) survivors. Yet, their association is often poorly understood. In this study, we wished to (1) describe neurocognitive difficulties and fatigue in a well-characterized cohort of long-term cALL survivors and (2) explore the risk of having neurocognitive deficits as a function of fatigue. Childhood ALL survivors (N = 285) from three Canadian treatment centers completed the DIVERGT battery of cognitive tests and the PedsQL Multidimensional Fatigue Scale. We performed logistic regressions to assess the risk of a survivor to show cognitive deficits (<2.0 SD) depending on their fatigue levels. At least one cognitive deficit on the DIVERGT was present in 31% of participants. Domains primarily affected were working memory, fine motor skills, and verbal fluency. Sleep/rest fatigue in youths was higher than norms (d = 0.35). The risk for cognitive deficits increased independently with levels of fatigue in the domains of cognitive speed and flexibility, working memory, and verbal fluency. For every 10-point increase on general or sleep/rest fatigue on the 0-100 scale, there was a median +23-35% risk of showing a deficit among the 7 tasks significantly associated with fatigue. Fatigue may constitute a complementary target when searching to mitigate cognitive issues in this population.

Prevalence and characterization of food insecurity in a Canadian paediatric emergency department.

Objectives: Food insecurity (FI) is associated with a number of adverse child health outcomes and increased emergency department (ED) use. The COVID-19 pandemic exacerbated the financial hardship faced by many families. We sought to determine the prevalence of FI among children with ED visits, compare this to pre-pandemic rates, and describe associated risk factors. Methods: From September to December 2021, families presenting to a Canadian paediatric ED were asked to complete a survey screening for FI along with health and demographic information. Results were compared to data collected in 2012. Multivariable logistic regression was used to measure associations with FI. Results: In 2021, 26% (n = 173/665) of families identified as food insecure compared to 22.7% in 2012 (n = 146/644) a difference of 3.3% (95% CI [-1.4%, 8.1%]). In multivariable analysis, greater number of children in the home (OR 1.19, 95% CI [1.01, 1.41]), financial strain from medical expenses (OR 5.31, 95% CI [3.45, 8.18]), and a lack of primary care access (OR 1.27, 95% CI [1.08, 1.51]) were independent predictors of FI. Less than half of families with FI reported use of food charity, most commonly food banks, while one-quarter received help from family or friends. Families experiencing FI expressed a preference for support through free or low-cost meals and financial assistance with medical expenses. Conclusion: More than one in four families attending a paediatric ED screened positive for FI. Future research is needed to examine the effect of support interventions for families assessed in medical care facilities including financial support for those with chronic medical conditions.

Survey of the use of traditional and complementary medicine among children with cancer at three hospitals in Cameroon.

INTRODUCTION: There is lack of diagnostic and treatment resources with variable access to childhood cancer treatment in low- and middle-income countries (LMIC), which may lead to subsequent poor survival. The primary aim of this study was to determine the prevalence and types of traditional and complementary medicine (T&CM) used in Cameroon. Secondarily, we explored determinants of T&CM use, associated costs, perceived benefits and harm, and disclosure of T&CM use to medical team. METHODS: A prospective, cross-sectional survey among parents and carers of children younger than 15 years of age who had a cancer diagnosis and received cancer treatment at three Baptist Mission hospitals between November 2017 and February 2019. RESULTS: Eighty participants completed the survey. Median patient age was 8.1 years (IQR4.1-11.1). There was significant availability (90%) and use (67.5%) of T&CM, whereas 24% thought T&CM would be good for cancer treatment. Common T&CM remedies included herbs and other plant remedies or teas taken by mouth, prayer for healing purposes and skin cutting. Living more than five hours away from the treatment center (P = 0.030), anticipated costs (0.028), and a habit of consulting a traditional healer when sick (P = 0.006) were associated with the use of T&CM. T&CM was mostly paid for in cash (53.7%) or provided free of charge (29.6%). Of importance was the fact that nearly half (44%) did not want to disclose the use of TM to their doctor. CONCLUSION: Pediatric oncology patients used T&CM before and during treatment but were unlikely to disclose its use to the child's health care team.

Late effects care for childhood brain Tumor Survivors: A Quality-Improvement Initiative.

Childhood and adolescent brain tumor survivors are at risk for long-term consequences of therapy. We reviewed adherence to long-term follow-up (LTFU) guidelines, assessed provider perspectives, and studied the needs, experience and quality of life (QOL) of pediatric malignant brain tumor survivors in the McMaster Children's Hospital Neuro-Oncology clinic. LTFU areas for improvement were evaluated using an anonymous health provider needs assessment questionnaire. The Cancer Care Experience Questionnaire (CCEQ), Cancer Worry Scale (CWS), Self-Management Skills Scale (SMSS), and PedsQL measured parents/patients' needs and QOL. Individual care plans were based on the Children's Oncology Group (COG) LTFU guidelines. Based on 17 responses, staff perceived areas for improvement included: increased multi-disciplinary participation, improved patient education and increased surveillance for therapy-related late effects. Thirty-two families participated, most felt they received high-quality care. Mean cancer worry scores were low (71.8 (± 28.4)). Survivors reported limited self-management skills (58.5 (±18.2)), requiring support with medical needs and activities of daily living. Overall median QOL scores were 'good' (parental report 72.3 (±17.7), survivor 68.2 (±16.6)). Utilizing survivorship guidelines and assessments from patients, caregivers and health providers, we implemented improvements in our provision of neuro-oncology survivorship care. Lessons learned may assist other LTFU programs.

Nutritional traditional and complementary medicine strategies in pediatric cancer: A narrative review.

Traditional and complementary medicine (T&CM) strategies are commonly used by pediatric cancer patients. Nutritional approaches to T&CM include bioactive compounds, supplements, and herbs as well as dietary approaches. Pediatric cancer patients and their families commonly request and use nutritional T&CM strategies. We review the potential risks and benefits of nutritional T&CM use in pediatric cancer care and provide an overview of some commonly used and requested supplements, including probiotics, antioxidants, cannabinoids, vitamins, turmeric, mistletoe, Carica papaya, and others. We also discuss the role of specific diets such as the ketogenic diet, caloric restriction diets, whole-food diets, and immune modulating diets. There is a growing body of evidence to support the use of some T&CM agents for the supportive care of children with cancer. However, further study is needed into these agents and approaches. Open communication with families about T&CM use is critical.

A systematic review of integrative clinical trials for supportive care in pediatric oncology: a report from the International Society of Pediatric Oncology, T&CM collaborative.

PURPOSE: Traditional and complementary medicine (T&CM) use in children with cancer is well established among high-income, upper middle-income, low-middle-income, and low-income countries (HIC, UMIC, LMIC, LIC, respectively). In HIC, a developing body of evidence exists for several T&CM therapies; however, evidence in other income settings is less well described despite a significantly higher use when compared to reports from HIC. The aim of this systematic review was to evaluate the evidence for T&CM for a variety of supportive care indications among children with cancer. METHODS: We performed a systematic review following the PRISMA guidelines of randomized, controlled clinical trials from inception through September 2016. Our eligibility criteria were limited to T&CM studies performed in children and adolescents undergoing treatment for a pediatric malignancy. RESULTS: Of 6342 studies identified, 44 met inclusion criteria. Two clinical trials reported on acupuncture, 1 reported on aromatherapy, 9 evaluated massage therapy, and 32 reported on dietary supplements. Twenty-two studies were performed in HIC, 15 in UMIC, and 7 in LMIC. T&CM therapies were most commonly investigated for the prevention or management of mucositis, weight loss, and febrile neutropenia. Encouraging results were reported for select interventions; however, the majority of studies were classified as poor to fair quality. CONCLUSION: Our search revealed numerous clinical studies investigating the use of T&CM for supportive care purposes in pediatric oncology in HIC, UMIC, and LMIC. Although limited, these results could inform supportive care resource allocation and indicate where T&CM may serve to fill gaps where access to care may be limited.

Evaluation of a joint adult and pediatric clinic for cancer survivorship care.

OBJECTIVES: The best model of care for long-term follow-up of survivors of childhood cancer is uncertain. We describe the care experience provided by the joint adult/pediatric AfterCare Clinic at the McMaster Children's Hospital. Secondary outcomes include an evaluation of cancer worry, self-management skills, and loss to follow-up rates. METHODS: AfterCare Clinic patients aged 19-29 years were approached for study participation between January and March 2016. Data were collected from a cross-sectional survey, consisting of the Cancer Care Experience Questionnaire (CCEQ), Cancer Worry Scale (CWS), and Self-Management Skills Scale (SMSS). Responses were analyzed using descriptive statistics. RESULTS: Seventy-three (40%) patients participated in the survey, 17 (23%) anonymously. Demographic characteristics of the nonanonymous participants were representative of the total clinic cohort. Most respondents were satisfied with the quality of care and anticipatory guidance provided, demonstrated by the CCEQ responses. Respondents had a high degree of cancer worries (mean score 50.6 [±18.4]), but good self-management skills (72.0 [±10.9]). Our 5-year loss to follow-up rate was 3.8%. Sensitivity analyses showed no difference in responses between the total cohort and the nonanonymous participants. CONCLUSIONS: This sample of young adult survivors of childhood cancer had a higher degree of cancer worries and higher self-management skills scores than a younger cohort of survivors of childhood cancer in the literature. Given this, along with the positive care experience reported, and the low loss to follow-up rate, the joint adult/pediatric model of survivorship care appears to be meeting the needs of this population.

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.

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.

Smoking, Binge Drinking, and Drug Use Among Childhood Cancer Survivors: A Meta-Analysis.

INTRODUCTION: Childhood cancer survivors are at risk for late effects of therapy, some of which may be exacerbated by smoking, alcohol, or drug use. We undertook a meta-analysis of the literature to determine whether survivors engage in risk-taking behaviors at rates different from their peers/siblings. METHODS: Studies comparing current engagement in risk-taking behaviors between cancer survivors and siblings or matched peers were identified in MEDLINE (1946-), EMBASE (1947-), PsychINFO (1806-), and the Cochrane Controlled Trials Register. Two reviewers assessed publications for inclusion and extracted data independently. Studies were combined using inverse variance weighting to determine odds ratios (OR) and prevalence rates of risk-taking behaviors in survivors compared to controls. RESULTS: Fourteen of 1,713 studies satisfied inclusion criteria. Twelve assessed smoking, six binge drinking, and seven drug use. Among survivors, 22% (95% confidence interval 0.19, 0.26) smoked, 20% (0.08, 0.51) were binge drinkers, and 15% (0.10, 0.23) used drugs. Survivors were less likely than siblings to smoke (OR 0.68 [0.49, 0.96]) or binge drink (OR 0.77 [0.68, 0.88]), but similarly likely to use drugs (OR 0.33 [0.03, 3.28]). Survivors were less likely than matched peers to smoke (OR 0.54 [0.42, 0.70]) or use drugs (OR 0.57 [0.40, 0.82]), but equally likely to binge drink (OR 0.97 [0.38, 2.49]). CONCLUSIONS: Childhood cancer survivors engage in similar or lower rates of risk taking than their siblings/peers. Future studies should identify survivors most likely to benefit from focused interventions, and determine the impact of risk-taking behaviors on the risk for late effects of cancer therapy.

Long-Term Social Outcomes of Hyperfractionated Radiation on Childhood ALL Survivors.

BACKGROUND/OBJECTIVES: Childhood cranial radiation has irreversible neurocognitive effects. Hyperfractionated radiation therapy (HFX) for acute lymphoblastic leukemia (ALL) was randomized against conventionally fractionated radiation therapy (CFX) in the DFCI 87-01/91-01 trials attempting to minimize these effects. When neurocognitive testing 8-year posttreatment demonstrated no difference, this strategy was abandoned. The objective of this study was to evaluate late social outcomes among patients who received HFX compared to CFX as part of the DFCI 87-01/91-01 trials. METHODS: This retrospective chart review examined all patients treated according to the DFCI 87-01/91-01 trials at the McMaster Children's Hospital in Hamilton, Canada. Patients <18 years at diagnosis and who have attended follow-up clinic since January 1, 2000 were included in this study. Social outcomes and IQ test results were examined for trends. Demographics and outcomes were presented with descriptive statistics. RESULTS: We identified 57 DFCI 87-01/91-01 trial participants: 14 received HFX, 29 received CFX, and 14 received no radiation. There were no demographic differences between the groups. HFX survivors were more likely to be living independently (64% vs. 28%, P = 0.02) and engaged in long-term relationships (57% vs. 25%, P = 0.04) than CFX. Nonsignificant trends suggested that HFX survivors may be more financially independent, employed full-time, had fewer educational difficulties in school, and higher scores on neuropsychological testing. Data trends, although not significant, persisted in logistic regression analysis when accounting for age. CONCLUSION: Long-term social outcomes were better among ALL survivors who received HFX than CFX. A wider study involving all patients enrolled on DFCI 87-01/91-01 protocols should be conducted to reconsider radiation protocols for ALL.

Inferior survival among Aboriginal children with cancer in Ontario.

BACKGROUND: Pediatric cancer distribution and outcomes have not been examined in Canadian Aboriginal children. The objective of this study was to describe the distribution, event-free survival, and overall survival of Aboriginal children with malignancies who reside in Ontario compared with non-Aboriginal children. METHODS: This population-based study included 10,520 Ontario children (aged <18 years) who were diagnosed with cancer between 1985 and 2011. Patients were identified from the Pediatric Oncology Group of Ontario Networked Information System database. Aboriginal children were identified by self-reported ethnicity or postal code on a Native reserve at diagnosis. Descriptive statistics of the patients were presented and compared using the Fisher exact test. Event-free and overall survival probabilities were calculated for Aboriginal and non-Aboriginal children, described using Kaplan-Meier curves, and compared using log-rank tests. RESULTS: In total, 65 Aboriginal children and 10,364 non-Aboriginal children with malignancy were identified. The distribution of malignancy type was similar between the 2 groups. There were no significant differences in baseline characteristics, presence of metastatic disease, or treatment approach (clinical trial, standard of care, or individualized protocol) between the groups. The 5e-year event-free survival rate (± standard error) was 56.3% ± 6.2% among Aboriginal children versus 72.8% ± 0.4% among non-Aboriginal children (P = .0042), and the 5-year overall survival rate was 64% ± 6.0% versus 79.3 ± 0.4% (P = .0017), respectively. The cause of death did not vary according to Aboriginal ethnicity. CONCLUSIONS: Survival was significantly inferior among Aboriginal children who had cancer compared with non-Aboriginal children who had cancer in Ontario. Future studies are required to define the etiology of this disparity, evaluate the issue nationally, and create interventions to improve outcomes for Aboriginal children.

Outcome of children treated for relapsed acute myeloid leukemia in Central America.

BACKGROUND: Relapsed childhood acute myeloid leukemia (AML) outcomes have not been documented in resource-limited settings. We examined survival after relapse for children with AML (non-APML) and acute promyelocytic leukemia (APML) in Central America. PROCEDURE: We retrospectively evaluated outcomes of children with first relapse of AML (non-APML) and APML in Guatemala, Honduras, or El Salvador diagnosed between 1997 and 2011. Predictors of subsequent event-free survival (EFS) and overall survival (OS) were examined. RESULTS: We identified 140 children with relapsed AML (non-APML), and 24 with relapsed APML. Two-year subsequent EFS and OS (±SE) were 7.0 ± 2.5% and 9.1 ± 2.8%, respectively. Worse outcomes were associated with Hispanic or Indigenous heritage, white blood cell count at diagnosis ≥50 × 10(9) /L, and time to relapse <18 months. For those with relapsed APML, subsequent 2-year EFS and OS were 36.7 ± 10.8% and 43.4 ± 12.1%, although few patients survived beyond 3 years. 15.2% of all patients were managed solely with palliative intent following first relapse. CONCLUSIONS: Children with relapsed AML in Central America rarely survive, so palliative strategies should be considered following relapse in this population. However, children with late relapse or with APML may have a prolonged period of remission with second treatment, and consideration of re-treatment may be appropriate.

Understanding experiences and perspectives in addressing unmet social needs of children and families in a paediatric weight management program: a qualitative descriptive study.

OBJECTIVE: The objective is to describe the experiences and perceptions of caregivers who participated in a community systems navigator intervention that addressed unmet social needs. DESIGN, SETTING AND PATIENTS: A qualitative descriptive study with caregivers of children enrolled in a clinical trial addressing unmet social needs of families with children cared for in a tertiary pediatric weight management clinic, through community systems navigation. Participants were asked open-ended questions related to perceptions of social needs screening in clinical settings. Interviews were recorded and analysed using Braun and Clarke's six-phase approach to thematic analysis. RESULTS: Ten parent participants were interviewed. Social needs screening perception and acceptability varied between participants. Social needs screening was comfortable for most but stressful for others. Participants noted that trusting relationships promote comfort with sharing social needs information, and this data should be shared on the electronic health record if accurate and purposeful. They found the online screening tool convenient but thought it could also limit opportunities to elaborate. Some participants noted the intervention of community systems navigation helpful; however, others described the need for more tailored resources. CONCLUSIONS: Screening for unmet social needs in clinical settings is complex and should be family centred, including the consideration of the mode of screening, data sharing in the electronic health record and ensuing interventions. Perspectives of families should drive the design of future larger scale community navigation interventions to address unmet social needs in clinical settings.

Long-Term Cardiovascular Outcomes in Children and Adolescents With Hypertension.

Importance: Hypertension affects 6% of all children, and its prevalence is increasing. Childhood hypertension tracks into adulthood and is associated with subclinical cardiovascular disease; however, there is a lack of evidence linking childhood hypertension to cardiovascular outcomes, which may contribute to underdiagnosis and undertreatment. Objective: To determine the long-term associated risk of major adverse cardiac events (MACE) among children diagnosed with hypertension. Design, Setting, and Participants: This was a population-based, retrospective, matched cohort study conducted from 1996 to 2022. The study included all children (aged 3-18 years) alive in Ontario, Canada, from 1996 to 2021, who were identified using provincial administrative health databases. Children with prior kidney replacement therapy were excluded. Exposure: Incident hypertension diagnosis, identified by validated case definitions using diagnostic and physician billing claims. Each case was matched with 5 controls without hypertension by age, sex, birth weight, maternal gestational hypertension, prior comorbidities (chronic kidney disease, diabetes, cardiovascular surgery), and a propensity score for hypertension. Main Outcomes and Measures: The primary outcome was MACE (a composite of cardiovascular death, stroke, hospitalization for myocardial infarction or unstable angina, or coronary intervention). Time to MACE was evaluated using the Kaplan-Meier method and Cox proportional hazards regression. Results: A total of 25 605 children (median [IQR] age, 15 [11-17] years; 14 743 male [57.6%]) with hypertension were matched to 128 025 controls without hypertension. Baseline covariates were balanced after propensity score matching, and prior comorbidities were uncommon (hypertension vs control cohort: malignancy, 1451 [5.7%] vs 7908 [6.2%]; congenital heart disease, 1089 [4.3%] vs 5408 [4.2%]; diabetes, 482 [1.9%] vs 2410 [1.9%]). During a median (IQR) of 13.6 (7.8-19.5) years of follow-up, incidence of MACE was 4.6 per 1000 person-years in children with hypertension vs 2.2 per 1000 person-years in controls (hazard ratio, 2.1; 95% CI, 1.9-2.2). Children with hypertension were at higher associated risk of stroke, hospitalization for myocardial infarction or unstable angina, coronary intervention, and congestive heart failure, but not cardiovascular death, compared with nonhypertensive controls. Conclusions and Relevance: Children diagnosed with hypertension had a higher associated long-term risk of MACE compared with controls without hypertension. Improved detection, follow-up, and control of pediatric hypertension may reduce the risk of adult cardiovascular disease.

Outcome of children treated for relapsed acute lymphoblastic leukemia in Central America.

BACKGROUND: Outcomes for relapsed childhood acute lymphoblastic leukemia (ALL) have not been documented in resource-limited settings. This study examined survival after relapse for children with ALL in Central America. METHODS: A retrospective cohort study was performed and included children with first relapse of ALL in Guatemala, Honduras, or El Salvador between 1990 and 2011. Predictors of subsequent event-free survival (EFS) and overall survival (OS) were examined. RESULTS: There were 755 children identified with relapsed disease. The median time from diagnosis to relapse was 1.7 years (interquartile range, 0.8-3.1 years). Most relapses occurred during (53.9%) or following (24.9%) maintenance chemotherapy, and the majority occurred in the bone marrow (63.1%). Following the initial relapse, subsequent 3-year EFS (± standard error) and OS were 22.0% ± 1.7%, and 28.2% ± 1.9%, respectively. In multivariable analysis, worse postrelapse survival was associated with age ≥ 10 years, white blood cell count ≥ 50 × 10(9) /L, and positive central nervous system status at the original ALL diagnosis, relapse that was not isolated central nervous system or testicular, and relapse < 36 months following diagnosis. Site and time to relapse were used to identify a favorable risk group whose 3-year EFS and OS were 50.0% ± 8.9% and 68.0% ± 8.1%, respectively. CONCLUSIONS: Prognosis after relapsed ALL in Central America is poor, but a substantial number of those with favorable risk features have prolonged survival, despite lack of access to stem cell transplantation. Stratification by risk factors can guide therapeutic decision-making. Cancer 2013. © 2012 American Cancer Society.

Screening and addressing social needs of children and families enrolled in a pediatric weight management program: a protocol for a pilot randomized controlled trial.

BACKGROUND: There is a paucity of evidence to support interventions that address the social needs of children and families with chronic medical conditions. The primary objective of this pilot randomized controlled trial (RCT) is to assess the feasibility of an intervention that screens for and addresses the social needs of children and families enrolled in a pediatric weight management clinic. METHOD: We will conduct a single-center, pilot RCT of 40 families with children enrolled in a pediatric weight management program at a tertiary children's hospital in Ontario, Canada. Families who are experiencing unmet social needs will be randomized to either a community navigator or self-navigation of community resources. The primary feasibility outcomes and criteria for success include the following: (1) recruitment rates, will be successful if 80% of our target sample is met in the 6 months of recruitment; (2) uptake of intervention, will be considered successful if > 80% of families complete the intervention; and (3) follow-up of participants, will be considered successful if > 90% of participants complete all the study visits. The secondary outcomes include estimating the preliminary effects on body mass index, body composition, and quality of life at 6 months. The analysis of feasibility outcomes will be based on descriptive statistics, and analysis of secondary clinical outcomes will be reported as estimates of effect. We will not perform tests of significance since these analyses are purely exploratory. DISCUSSION: This study is important because it will aim to improve the treatment of pediatric obesity by testing the feasibility of an intervention that addresses unmet social needs.
