Clinical factors associated with fatigue over time in paediatric oncology patients receiving chemotherapy

Effect of Progressive Muscle Relaxation on Sleep Quality and Side Effects of Chemotherapy in Children with Cancer: Randomized Clinical Trial

BACKGROUND: Sleep disturbance affects quality of life in children receiving chemotherapy. AIM: The aim of this study was to identify the effect of progressive muscle relaxation on the sleep quality and side effects of chemotherapy in children with cancer. METHODS: This study used randomized clinical trial with single blind method, where 30 children were allocated randomly to the control group and intervention group. The intervention group received progressive muscle relaxation twice a day, in the morning and evening, 15 minutes each session for 7 days. Control group received routine nursing care. RESULTS: The study concluded there was no significant difference in the two groups on fatigue and pain. However, progressive muscle relaxation had significant relation to decreased sleep quality score. CONCLUSION: Relaxation therapy, particularly progressive muscle relaxation, may be one of the nursing cares to improve sleep quality and reduce the side effects of chemotherapy in children with cancer.

Self-Reported Fatigue in Chinese Children and Adolescents During Cancer Treatment

Background: Fatigue is a prevalent and distressing symptom in children and adolescents with cancer. Objectives: This study aimed to (1) investigate the current fatigue status reported by Chinese children and adolescents with cancer during active cancer treatment and (2) examine whether sociodemographic information, disease and treatment information, co-occurring symptoms, function and related clinical data are significantly associated with fatigue according to the biopsychosocial model. Methods: Participants were children aged 8-17 years, who had undergone treatment for cancer at four hospitals in China. Children completed the Chinese version of the Pediatric Patient-Reported Outcomes Measurement Information System short forms. Results: In total, 187 children (33.16% female, mean age 10.28 years) participated. The mean T-score for child-reported fatigue was 48.52 (34-72). Multiple linear regression analysis showed that fatigue in pediatric active cancer treatment could be significantly predicted by greater child-reported pain interference (β = 0.391, p < .001), greater depressive symptoms (β = 0.443, p < .001), and reduced mobility (β = -0.226, p = .004) (adjusted R² = 0.613, F = 16.476, p < .001). Conclusions: Children and adolescents with cancer experience multiple, intersecting troubling symptoms during their treatment. There is a need to attend to the biopsychosocial aspects of care for children and adolescents during active cancer treatment. To reduce pediatric oncology patients' fatigue level, clinicians could develop culturally sensitive interventions to alleviate children's pain interference, treat depressive symptoms, and maximize their physical mobility.

Cerebrospinal Fluid Metabolomic Profiles Associated With Fatigue During Treatment for Pediatric Acute Lymphoblastic Leukemia

CONTEXT

Cancer-related fatigue (CRF) is one of the most distressing and persistent symptoms reported during pediatric acute lymphoblastic leukemia (ALL) therapy; however, information on the pathways underlying CRF severity is limited.

OBJECTIVES

We conducted global metabolomics profiling of cerebrospinal fluid (CSF) samples to provide insight into the underlying mechanisms of CRF.

METHODS

Fatigue in pediatric ALL patients (2012-2017) was assessed during postinduction therapy approximately six months after diagnosis. Postinduction CSF was collected from 171 participants, comprising discovery (n = 86) and replication (n = 85) cohorts. We also conducted secondary validation using diagnostic CSF from 48 replication cohort participants. CSF metabolomic profiling was performed using gas chromatography-mass spectrometry (MS) and liquid chromatography-MS/MS. Kendall's rank correlation was used to evaluate associations between metabolite abundance and CRF. False discovery rate was used to account for multiple comparisons.

RESULTS

Participants were 56% males and 59% Hispanic with a mean age at diagnosis of 8.5 years. A total of 274 CSF-derived metabolites were common to the discovery and replication cohorts. Eight metabolites were significantly associated with fatigue in the discovery cohort (P < 0.05), of which three were significant in the replication cohort, including false discovery rate-corrected associations with gamma-glutamylglutamine (P_combined = 6.2E-6) and asparagine (P_combined = 3.5E-4). Notably, the abundance of gamma-glutamylglutamine in diagnostic CSF samples was also significantly associated with fatigue (P = 0.0062).

CONCLUSION

The metabolites identified in our assessment have been implicated in neurotransmitter transportation and glutathione recycling, suggesting that glutamatergic pathways or oxidative stress may contribute to ALL-associated CRF. This information could inform targeted therapies for reducing CRF in at-risk individuals.

Italian nurses knowledge and attitudes towards fatigue in pediatric onco-hematology: A cross-sectional nationwide survey

Background and Objective

Fatigue is one of the most debilitating and prevalent symptoms in pediatric cancer patients and it is important to know if nurses are able to recognize and manage it. The aim of this study was to investigate the knowledge and attitudes towards fatigue of nurses working in Italian pediatric onco-hematology centers.

Methods

Cross-sectional online survey. An existing questionnaire was adapted to the Italian context, extended with a section on attitudes, and psychometrically tested. The questionnaire was sent to all nurses working in Italian pediatric onco-hematology centers.

Results

Respondents (n = 189), who were working in 37/53 (∼70%) centers, reported 42% of children and 68% of adolescents experiencing fatigue, with intensity increasing with age. Contributing factors were treatments and co-morbidities; frequent symptoms were mood changes and lack of energy. Among respondents who did not assess fatigue, 36.2% did not know an appropriate tool. Nurses recognized fatigue as an important problem and their knowledge and attitudes towards fatigue seemed satisfactory.

Conclusion

This study provides nurses with an instrument to investigate their knowledge and attitudes about fatigue. Nurses' awareness of the significance of fatigue is a fundamental step towards improving its management and offering strategies that can help both the child and their family.

Concordance between paediatric self-reports and parent proxy reports on fatigue: A multicentre prospective longitudinal study

PURPOSE

To investigate the degree of concordance on fatigue assessment between children and adolescents with cancer and their parents, and its changes over time.

METHOD

Multicentre longitudinal study.

RESULTS

Data from 134 dyads were analysed. The mean age of patients was 11.7 years; caregivers had a mean age of 44.1 years. Almost 90% of patients already reported mild or moderate fatigue at the time of diagnosis, decreasing to 69.7% after one year. Concordance on the total fatigue improved over time for the total sample, moving from moderate at the time of diagnosis to good concordance after one year.

CONCLUSIONS

This was the first study with a longitudinal design investigating concordance between paediatric self-reports and parent proxy reports on fatigue. It showed how concordance between proxies and patients changed over time reaching a good level after one year from the cancer diagnosis.

Fatigue, Participation and Quality of Life in Adolescents and Young Adults with Acquired Brain Injury in an Outpatient Rehabilitation Cohort

PURPOSE

To study the association between fatigue and participation and QoL after acquired brain injury (ABI) in adolescents and young adults (AYAs).

MATERIALS & METHODS

Cross-sectional study with AYAs aged 14-25 years, diagnosed with ABI. The PedsQL™ Multidimensional Fatigue Scale, Child & Adolescent Scale of Participation, and PedsQL™4.0 Generic Core Scales were administered.

RESULTS

Sixty-four AYAs participated in the study, 47 with traumatic brain injury (TBI). Median age at admission was 17.6 yrs, 0.8 yrs since injury. High levels of fatigue (median 44.4 (IQR 34.7, 59.7)), limited participation (median 82.5 (IQR 68.8, 92.3)), and diminished QoL (median 63.0 (IQR 47.8, 78.3)) were reported. More fatigue was significantly associated with more participation restrictions (β 0.64, 95%CI 0.44, 0.85) and diminished QoL (β 0.87, 95%CI 0.72, 1.02).

CONCLUSIONS

AYAs with ABI reported high levels of fatigue, limited participation and diminished quality of life with a significant association between fatigue and both participation and QoL. Targeting fatigue in rehabilitation treatment could potentially improve participation and QoL.

Symptoms in Children Receiving Treatment for Cancer-Part I: Fatigue, Sleep Disturbance, and Nausea/Vomiting

Children and adolescents with cancer often undergo intensive chemotherapy treatment to obtain remission and long-term survival. The pursuit of successful treatment outcomes may lead to high levels of symptom distress related to treatment side effects and toxicities. The Children's Oncology Group Nursing Discipline held a State of the Science Symposium "Symptom Assessment During Childhood Cancer Treatment" in 2018 that included reviews of evidence regarding key symptoms. The purpose of this review is to summarize and synthesize the evidence presented about the prevalence, relationships, trajectories, and associated biomarkers of selected symptoms experienced by children and adolescents during cancer treatment. Five symptoms were selected, with the focus on fatigue, sleep disturbance, and nausea/vomiting and included in Part I of the review. Using Ovid-Medline, studies published between 2008 and 2018 that focused on these specific symptoms during active chemotherapy treatment were selected. Fatigue interferes with normal developmental activities and is associated with sleep disturbances, and its pattern changes within a cycle of chemotherapy as well as across the treatment trajectory. Sleep is disrupted by the hospital environment, treatment medications, and changes in normal childhood and schedules. Disturbances of sleep persist during treatment, preventing recovery from poor quality sleep. Although pharmacologic interventions have advanced for treatment of nausea and vomiting, children and adolescents continue to struggle with this symptom. Its trajectory changes with the intensity of treatment, and over half of the patients report that they experience nausea and/or vomiting. Future research is needed to advance identification of biologic risk factors for symptoms and test effectiveness of symptom-related interventions.

Childhood Cancer-Related Fatigue and Day-to-Day Quality of Life

Childhood cancer-related fatigue is often viewed as an inevitable symptom of cancer and cancer treatment leading to underassessment by health care providers and self-management by families in the home and hospital environment. Parents' perspectives of the influence of childhood cancer-related fatigue on their child's day-to-day life is needed to understand how parents may or may not prioritize, report, and/or manage the fatigue symptom. This qualitative study used conventional content analysis to describe parents' observations and perspectives on the influence of fatigue in their child's day-to-day quality of life (QOL). Eleven interviews were gathered from parents. The concept childhood cancer-related fatigue and domains of QOL in pediatric oncology patients were used to guide the study, construct interview questions, and conduct conventional content analysis. A synthesis of three categories and seven codes led to three major findings: (a) parents perceive their child's symptoms as co-occurring not as a discrete entity of fatigue, (b) parents accept the child's behavior as a "new normal," and (c) parents recognize fatigue as a warning sign. The study findings reveal differences in how parents observe childhood cancer-related fatigue and how they perceive the symptom influences day-to-day QOL. Findings of this study support current guidelines underscoring the importance of multidimensional fatigue care. Additionally, the findings suggest a standardized multiple symptom instrument may be helpful in assessing symptom experience.

Interventions minimizing fatigue in children/adolescents with cancer: An integrative review

Fatigue is among the most common, debilitating, and distressing symptoms associated with chronic condition in pediatric population. The purpose of this study was to identify non-pharmacological fatigue interventions in children and adolescents with cancer. For this, we carried out an integrative review of the literature from January 2000 to December 2016. A comprehensive search of four databases was conducted: Cumulative Index to Nursing and Allied Health Literature, Psychology Information, Medline via PubMed, and Web of Science. Randomized controlled trial, quasi-experimental, case-control and cohort studies were included in this review. Thirteen relevant studies were included for analysis. Seven papers reported positive outcomes for exercise, exercise plus leisure activities, healing touch and acupressure. In another six papers using exercise, exercise plus psychological intervention and massage, no effectiveness was found. Effective management of fatigue in children and adolescents is important but research in this area is limited, so the results of this review should be interpreted cautiously. Future researchers are encouraged to test the effective interventions in homogenous cancer populations and in other groups where fatigue is a common concern.

Perspectives of children, family caregivers, and health professionals about pediatric oncology symptoms: a systematic review

OBJECTIVES

To evaluate the existing body of evidence to determine the current state of knowledge regarding the perspectives of the following groups: (1) children with cancer, (2) family caregivers, and (3) healthcare professionals, about symptoms, as well as factors that may influence the symptom reports.

METHODS

A systematic search was performed for all types of studies that included the perspectives of at least two groups of participants' symptom reports. Children included anyone younger than 19 years of age who was diagnosed with any type of cancer. Electronic searches were conducted in five English databases and four Chinese databases. The appraisal of methodological quality was conducted using the GRADE criteria. Data were extracted into matrix tables.

RESULTS

Thirty-three studies were included. The pediatric oncology symptoms reported by children, family caregivers, and healthcare professionals were synthesized. Findings suggested that family caregivers' symptom reports were more closely aligned with children's reports than with the healthcare professionals' reports. Influencing factors on the different symptom reports included the children's diagnosis, symptom characteristics, social-demographic factors, and family caregivers' psychosocial status.

CONCLUSIONS

Children with cancer should be the primary reporters for their symptoms. When there are reporters other than the children, the potential discrepancy between the different perspectives needs to be carefully considered.

Physical training interventions for children and teenagers affected by acute lymphoblastic leukemia and related treatment impairments

A decreased physical fitness has been reported in patients and survivors of acute lymphoblastic leukemia (ALL). This is influenced by the negative effects of the disease and by the treatments of childhood cancer.

In the past, children were advised to recover in bed, and to take as much relax as possible. Nowadays, it is considered that too much immobility may result in a further decrease of physical fitness and functioning. Exercise training for ALL children has frequently been reported to improve physical fitness and the well-being of the children, since it prevents the negative effects of a sedentary life-style, such as obesity and a poor skeletal health. In recent years, different studies and protocols on this subject has become available for children and young adults with cancer, both during and after treatment.

The efficacy of recent physical exercise training interventions, that act on several ALL impairments in children such as skeletal, musculoskeletal, neuromuscular, cardiopulmonary and cardiovascular systems, fatigue, body balance disorders and metabolism alterations have been examined.

These side effects might be prevented or significantly reduced by introducing a physical exercise program during or shortly after cancer treatment. Several interventions are discussed and presented for each impairment, reducing their level caused by the disease and thus suggesting the importance of physical training activity in ameliorating the children quality of life.

Assessment of Nutritional Problems in Pediatric Patients with Cancer and the Information Needs of Their Parents: A Parental Perspective

Objective:

The majority of problems and symptoms occur in the gastrointestinal system in children with cancer. Parents have difficulty in coping with the nutritional problems and changing routines of children and need support in this respect. This study aimed to assess the nutritional problems of children with cancer and the information needs of their parents.

Methods:

This descriptive study was performed among children with cancer aged 3–18 years and their parents (n = 69). The data were collected through a data collection form developed by the researchers based on the literature.

Results:

The most prominent nutritional problems experienced by children were loss of appetite (85.5%), nausea (84.1%), vomiting (81.2%), fatigue (79.7%), and mucositis (66.7%). According to the parents, the factors causing these nutritional problems in children were physiological factors (100%) and the foods given to children in the hospital (65.2%). The parents mostly needed information about food–drug interactions (58.0%), food–disease interactions (52.2%), foods that children with neutropenia should avoid or should eat (neutropenic diet) (46.4%), and frequency of nutritional intake (36.2%).

Conclusions:

This study has shown that most children experience at least one nutritional problem, and the parents need comprehensive and regular information about nutrition. Pediatric oncology nurses have a significant responsibility in the evaluation, education, and monitoring of these children.

Fatigue and health related quality of life in children and adolescents with cancer

PURPOSE

The study examined the different dimensions of fatigue (general, sleep/rest, cognitive), health related quality of life (HRQL) (physical, emotional, cognitive, social), and the relationships between fatigue and HRQL in hospitalized children and adolescents with cancer in Brazil.

METHOD

Participants were recruited from a pediatric oncology inpatient unit in a comprehensive cancer care hospital in southeast Brazil. They completed the PedsQL Multidimensional Fatigue Scale and the PedsQL Inventory of Quality of Life (Generic and Cancer module) once during hospitalization.

RESULTS

The majority (66.7%) of the participants (n = 38; mean age 12.1 ± 2.9 years) had total fatigue scores < 75 on 0 to 100 scale; with the mean total fatigue score of 63.8 ± 18.5. The majority (72.2% generic; 83.3% cancer modules) had total PedsQL scores < 75 on 0 to 100 scale. The mean PedsQL score on generic module (61.1 ± 17.0) was similar to the mean PedsQL score cancer module (59.1 ± 16.7). Significant correlations were found between total fatigue and quality of life generic (r = 0.63, p = 0.000) and cancer module (r = 0.74, p = 0.000).

CONCLUSIONS

The study is the first to report fatigue and health related quality of life in hospitalized children and adolescents with cancer in Brazil. Similar to experiences of other children in the world, our findings indicate that children and adolescents with cancer had problems with fatigue that were associated with low HRQL. Future studies are recommended to examine interventions (exercise, leisurely activities) that may alleviate fatigue and improve HRQL in pediatric patients with cancer.

Fatigue and Oxidative Stress in Children Undergoing Leukemia Treatment

Fatigue is a frequent and distressing symptom in children undergoing leukemia treatment; however, little is known about factors influencing this symptom. Antioxidants such as glutathione can decrease symptom severity in adult oncology patients, but no study has evaluated antioxidants' effects on symptoms in pediatric oncology patients. This study describes fatigue patterns and associations of fatigue with antioxidants represented by reduced glutathione (GSH) and the reduced/oxidized glutathione (GSH/GSSG) ratio among children receiving leukemia treatment. A repeated measures design assessed fatigue and antioxidants among 38 children from two large U.S. cancer centers. Fatigue was assessed among school-age children and by parent proxy among young children. Antioxidants (GSH and GSH/GSSG ratio) were assessed from cerebrospinal fluid at four phases during leukemia treatment. Young children had a steady decline of fatigue from the end of induction treatment through the continuation phase of treatment, but no significant changes were noted among the school-age children. Mean antioxidant scores varied slightly over time; however, the GSH/GSSG ratios in these children were significantly lower than the normal ratio. Mean GSH/GSSG ratios significantly correlated to fatigue scores of the school-age children during early phases of treatment. Children with low mean GSH/GSSG ratios demonstrated oxidative stress. The low ratios noted early in therapy were significantly correlated with higher fatigue scores during induction and postinduction treatment phases. This finding suggests that increased oxidative stress during the more intensive phases of therapy may explain the experience of fatigue children report.

Use of a Fitness Tracker to Promote Physical Activity in Children With Acute Lymphoblastic Leukemia

BACKGROUND

Children with cancer identify fatigue as a pervasive symptom, which increases during the corticosteroid pulse in acute lymphoblastic leukemia (ALL) maintenance. The FitBit is a fitness tracker that downloads activity measurements to the Internet in real time. In this feasibility study, we explored if children who received daily FitBit coaching for 2 weeks before a maintenance steroid pulse had an increase in steps per day and determined the relationship between steps per day prepulse and fatigue postpulse.

PROCEDURE

Seventeen children in ALL maintenance, aged 6-15, wore the FitBit for 3 days to establish a baseline. A tailored weekly step goal was then set with the child and parent. Daily emails with feedback and FitBit screenshots were sent over the 2-week intervention. Self-report of fatigue was measured at baseline, after 2 weeks (i.e. before the steroid pulse), and after 5 days of steroids.

RESULTS

There was a trend toward increased steps per day from weeks 1-2 (P = 0.079); fatigue was low and did not increase during the corticosteroid pulse. A significant correlation (r = -0.66, P = 0.005) was found between the steps per day during week 2 and fatigue after the steroid pulse with higher steps associated with lower fatigue.

CONCLUSIONS

The intervention was feasible in this small sample. The average steps each time period (week 1, week 2, and during steroids) was over 10,000, demonstrating that children with ALL can be active during treatment. Physical activity may be protective of fatigue during a corticosteroid pulse.

The influence of oxidative stress on symptom occurrence, severity, and distress during childhood leukemia treatment

PURPOSE/OBJECTIVES

To explore the symptom trajectory during the first 16 months of childhood leukemia treatment and any associations with the oxidative stress pathway measured by cerebrospinal fluid (CSF) concentration of oxidized phosphatidylcholine (PC), the predominant glycerophospholipid in the brain and cell membranes.

DESIGN

Prospective, longitudinal design.

SETTING

Two cancer centers in the southwestern United States.

SAMPLE

36 children (aged 3-14 years) newly diagnosed with acute lymphoblastic leukemia.

METHODS

Symptoms were measured using the Memorial Symptom Assessment Scale at six specific time points during treatment. Biochemical changes in oxidative stress were measured by oxidized PC in the CSF.

MAIN RESEARCH VARIABLES

Childhood cancer symptoms, oxidized PC.

FINDINGS

Significant differences were found in the number of symptoms experienced during the three phases of treatment. Symptom trajectory changes and influence of the oxidative stress pathway on symptom experiences were identified.

CONCLUSIONS

Symptoms experienced during treatment for childhood leukemia are associated with increased oxidative stress.

IMPLICATIONS FOR NURSING

Children with leukemia experience symptoms throughout treatment. Physiologic measures indicate the influence of oxidative stress on symptoms.

The effects of dexamethasone on sleep in young children with acute lymphoblastic leukemia

PURPOSE

Corticosteroids, which are a mainstay in the treatment of acute lymphoblastic leukemia (ALL), have a well-documented adverse effect on sleep. We sought to characterize the effects of dexamethasone on sleep over an entire 28-day treatment cycle using actigraphy, an objective measure of sleep.

METHODS

The sleep of 25 children aged 2-9 years (mean 4.5 years) with ALL treated with dexamethasone were evaluated during maintenance chemotherapy using a within-subject experimental design, actigraphy, and standardized questionnaires to assess sleep, sleep problems, and fatigue.

RESULTS

During the five days of dexamethasone treatment, sleep time increased during the night (535 vs. 498 min; p = 0.004) and daytime napping increased the following day (14 vs. 0 min; p = 0.002), and the number of wake episodes during the night was lower (14 vs. 20; p =  ≤ 0.001). However, when assessed individually, sleep-onset time, efficiency, and wake after sleep onset during the night were unchanged during dexamethasone treatment; when the cumulative effect of all of these factors was assessed, there was a statistically and clinically significant increase in nighttime sleep duration during dexamethasone treatment.

CONCLUSIONS

During the five days of treatment with dexamethasone, an increase in nighttime sleep as well as daytime napping was observed in young children with ALL. The increases in sleep duration return to baseline one day after the discontinuation of dexamethasone.

Sleep and fatigue in pediatric oncology: A review of the literature

Cancer in children has detrimental effects on sleep patterns and sleep quality, which in turn impacts on the perception of, and the ability to cope with, the emotional and physical challenges associated with both the disease and its treatment. This places an added burden on their quality of life that can last many years beyond diagnosis and treatment. In addition to the effect of the cancer itself, surgery, chemotherapy and radiotherapy can all contribute both short and long term to sleep disruption. Sleep disorders have also been associated with pain, fatigue, medication and hospitalisation in children suffering from cancer. This review will explore the relationship between childhood cancer and associated sleep disorders, in the acute stage of diagnosis, during treatment and in the years following. We will discuss the possible causes and the current treatment modalities used to treat sleep disorders in children with cancer, and in childhood cancer survivors. It has been estimated that the recent advances in treatment have improved the overall five year survival rate for all childhood cancers to over 80%, with some cancers achieving a near 100% cure rate such as early stage Wilms' tumour. Thus, recognition and appropriate treatment of associated sleep disorders is essential to optimise long term quality of life.

Measurement of fatigue in children and adolescents with cancer: an integrative review

This study analyzed scientific production on the measurement of fatigue in children and adolescents with cancer, particularly the instruments used. Integrative review, searching in PubMed, PsycINFO, Web of Science, CINAHL, LILACS, SciELO, IBECS and COCHRANE, without any time restriction, using key words and descriptors in different combinations. The review sample comprised 21 references. The results composed two categories: instrument development and validation and fatigue measurement. American nurses developed most studies, between 2002 and 2011, using two scales. The studies assessed the children and adolescents' self-reports and the parents' reports. They also associated fatigue with sleep pattern, quality of life, depression, survival and dexamethasone use. The importance of research on this theme is evidenced, including studies that apply these instruments in practice. The gap in knowledge production on this theme is highlighted in the Brazilian context.

Fatigue in adolescents and young adults with sickle cell disease: biological and behavioral correlates and health-related quality of life

This descriptive, correlational study examined fatigue and potential biological and behavioral correlates in adolescents and young adults with sickle cell disease. Sixty adolescents and young adults with sickle cell disease completed the Brief Fatigue Inventory, Multidimensional Fatigue Symptom Inventory-Short Form, Patient Reported Outcomes Measurement Information System (PROMIS) fatigue short form and measures of pain, sleep quality, anxiety, depressive mood, stress, disease severity, and quality of life. Blood samples were obtained for hemoglobin and cytokines. Fatigue scores were mostly moderate in severity. Fatigue interfered to a moderate degree with daily activities and correlated significantly with pain, sleep quality, state and trait anxiety, depressive mood, stress, and quality of life. Fatigue was correlated with hemoglobin on the PROMIS measure. Fatigue was not correlated with cytokines or age, nor differed by disease severity. Fatigue was common in these adolescents and young adults, interfered with daily activities such as school, work and exercise, and significantly correlated with several potentially modifiable factors. As life expectancy increases in sickle cell disease, research is needed to test interventions to reduce fatigue.

A pilot exploration of symptom trajectories in adolescents with cancer during chemotherapy

BACKGROUND

Chemotherapy is frequently administered in repetitive cycles. Adolescents with cancer have multiple symptoms related to chemotherapy, but knowledge of symptom trajectories across a cycle is limited. Examining trajectories over a cycle may reveal key periods to manage symptoms.

OBJECTIVES

The aims of this pilot were to describe the trajectory of symptoms (pain, sleep, appetite, nausea, fatigue) and biological and behavioral variables (anxiety, stress, hematologic function) across 1 cycle and examine relationships between variables.

METHODS

Nine adolescents with cancer within 6 months of diagnosis participated. Data were collected by surveys, chart review, and biologic measures on days 1 and 2 of the cycle, 1 week later (nadir), and day 1 of the following cycle. To evaluate the trajectory, a simple random-effects repeated-measures analysis was computed.

RESULTS

The significant trajectories were fatigue (P = .003), difficulty sleeping (P = .032), and nausea (P = .04). Most of the adolescents reported some anticipatory anxiety about receiving chemotherapy. Significant correlations between symptoms and biobehavioral variables included anticipatory anxiety and nausea (r = .86, P = .003), trait anxiety and fatigue (r = -0.82, P < .001), and stress and pain (r = 0.78, P = .039).

CONCLUSIONS

Multiple symptoms were experienced across the cycle. Three symptoms displayed significant trajectories indicating that patterns of symptoms may be anticipated.

IMPLICATIONS FOR PRACTICE

Pilot findings suggest that monitoring symptoms, stress, and anxiety across a cycle is important, not only during chemotherapy administration, but also prior to being admitted for chemotherapy.

Fatigue in adolescents with cancer compared to healthy adolescents

BACKGROUND

Cancer-related fatigue is one of the most pervasive and debilitating side-effects of cancer treatment and adolescents consistently rate cancer-related fatigue as one of the most distressing aspects of treatment. Because fatigue is also high in adolescents without cancer, the current study aims to describe fatigue in adolescents with cancer relative to a control group and to identify associates of such fatigue. Knowing this is important for understanding the extent of the problem in adolescents with cancer relative to healthy adolescents and for understanding who is most at risk for fatigue and related distress.

PROCEDURE

Adolescents with cancer and their caregivers (n = 102) and adolescents without a history of chronic health conditions and their caregivers (n = 97) completed the Multidimensional Fatigue Scale and measures of depression, quality of life (QoL), affect, coping, and family functioning.

RESULTS

Adolescents with cancer and their caregivers reported significantly more adolescent fatigue across all domains (with the exception of adolescent reports of cognitive fatigue) relative to adolescents without chronic health conditions. Higher fatigue was significantly related to adolescent report of more symptoms of depression, poorer QoL, higher negative affect, less positive affect, and behavioral disengagement coping style. Fatigue was not related to active coping or family functioning.

CONCLUSIONS

Adolescents with cancer experience significantly more fatigue than peers without chronic health conditions. Reports of fatigue are closely related to multiple indicators of psychosocial well-being, suggesting that fatigue may be an important cancer-related symptom to assess and manage to improve adolescent QoL.

Psychometric properties of instruments used to measure fatigue in children and adolescents with cancer: a systematic review

CONTEXT

Despite the recognized distressing symptom of fatigue in children with cancer, little information is available to assist in the selection of an instrument to be used to measure fatigue.

OBJECTIVES

The objectives of this study were to 1) describe the instruments that have been used to measure cancer-related fatigue in children and adolescents and 2) summarize the psychometric properties of the most commonly used instruments used to measure fatigue in children and adolescents with cancer.

METHODS

Five major electronic databases were systematically searched for studies using a fatigue measurement scale in a population of children or adolescents with cancer. Fatigue scales used in those studies were included in the review.

RESULTS

From a total of 1753 articles, 25 were included. We identified two main fatigue measurement instruments used in a pediatric oncology population: 1) the Fatigue Scale-Child/Fatigue Scale-Adolescent and the proxy report versions for parents and staff and 2) the PedsQL™ Multidimensional Fatigue Scale. These two scales show similar attributes with reasonably good internal consistency and responsiveness.

CONCLUSION

Either the Fatigue Scale or PedsQL Multidimensional Fatigue Scale can be incorporated into clinical research. Future research should focus on identifying specific fatigue measures more suited to different purposes such as comparative trials or identification of high-risk groups.

Reduction in nausea and vomiting in children undergoing cancer chemotherapy by either appropriate or sham auricular acupuncture points with standard care

BACKGROUND

Over 40% of children with cancer have reported that chemotherapy-induced nausea and vomiting (CINV) are the two most distressing side-effects of treatment even when antiemetic drugs have been used.

OBJECTIVES

The purpose of this article is to report the findings from a feasibility and pilot study using auricular point acupressure point for CINV in a small group of children in Taiwan.

METHODS

This was a crossover randomized design study. CINV symptoms were assessed on 10 patients just prior to and for 7 days following each of three rounds of chemotherapy drugs (CTX). They received standard care (SC) and were not entered into a test treatment group until they completed the baseline assessment, which was conducted during their first round of chemotherapy after entering the study. Just prior to receiving the second round of CTX, patients were randomized into one of two treatment conditions: auricular acupressure intervention, in addition to standard care (AAP) or auricular acupressure using sham auricular points (SAP) in addition to standard care. For the third round of CTX, they were switched to the other treatment group.

RESULTS

The enrollment rate for this study was 77% of the children invited to participate and of those, 88% provided completed data sets for all three treatment conditions. Patients in the AAP group reported significantly lower occurrence and severity of nausea and vomiting than patients in the SC group (p<0.05). There were no significant differences of nausea and vomiting for patients between the AAP and SAP groups. All of the patients took antiemetic medication on the day they received CTX, and 80% of patients reported that the antiemetics did not help to treat CINV.

CONCLUSIONS

These preliminary findings did show evidence that AAP is acceptable to the children and their parents to prevent/treat CINV. However, there were no statistically significant differences between the AAP and SAP groups in the prevention/treatment of CINV. There were clinical trend differences between the groups, which may due to the small sample size. In a larger study, it would be important to determine whether the effects of the AAP and SAP treatment are independent of any psychologic effects, such as the researcher's increased presence in both treatment groups.

Review of symptom experiences in children and adolescents with cancer

BACKGROUND

Inadequate symptom relief in children and adolescents with cancer leads to unnecessary suffering. This review assesses research on children and adolescents with cancer that had been published from 2002 to 2010.

OBJECTIVES

The review identifies the symptom experiences of children and adolescents undergoing treatment and describes the progress that has been made since Docherty's 2003 systematic review of nurse researcher published studies from 1990 to 2002, which identified gaps in research on the symptoms of pediatric oncology patients.

METHOD

A computerized search of medical and nursing literature produced 50 published studies and 2 dissertations that addressed the symptom experiences of children and adolescents receiving treatment for cancer.

RESULTS

Pain from cancer-related procedures and fatigue were the most frequently identified symptoms, followed closely by nausea and vomiting. More preschool-aged subjects and nonwhite subjects need to be assessed, distinctions between age groups and gender should be explored, and instrumentation for the prereading group must be developed.

CONCLUSIONS

Research on symptoms experienced by children and adolescents has gained momentum within the last 10 years, and some of the gaps identified by Docherty have been addressed. Multicenter trials would increase sample sizes and decrease enrollment time.

IMPLICATIONS FOR PRACTICE

By synthesizing research completed from 2002 to 2010 on symptoms of children who had cancer, new ideas can be generated and shared with clinical nursing staff to improve patient care. Gaps to further direct research are also identified.

Fatigue in survivors of childhood acute lymphoblastic and myeloid leukemia in Japan

BACKGROUND

Fatigue in cancer survivors is a serious problem in pediatric oncology, but reports on this issue are limited, especially in Asian countries.

METHODS

Sixty-three patients with acute lymphoblastic leukemia and 18 patients with acute myeloid leukemia who attended a follow-up outpatient clinic were enrolled. Participants were required to be >8 years of age, in remission, and without any cancer treatment for at least the previous 1 year. A control group consisted of 243 subjects whose age and gender were matched with the patient group. A questionnaire consisting of 12 items was devised for fatigue measurement.

RESULTS

Principal factor analysis identified three dimensions, defined as physical fatigue, decreased function, and altered mood. The mean total and the three fatigue dimension scores tended to be higher in the control group, but significant differences between the scores were seen only in the total and physical fatigue scores. Multiple regression analysis indicated an association of present older age or shorter duration after completion of treatment with total and physical fatigue, and an association of presence of total body irradiation with decreased function.

CONCLUSION

Pediatric leukemia survivors in Japan experience equal or less fatigue compared with that of controls in different fatigue dimensions. Elucidation of underlying mechanisms of cancer-related fatigue including the differences of cultural background among different countries is necessary for future study of this issue.

Sleep problems in children and adolescents with common medical conditions

Untreated sleep disturbances and sleep disorders pose significant adverse daytime consequences and place children at considerable risk for poor health outcomes. Sleep disturbances occur at a greater frequency in children with acute and chronic medical conditions compared with otherwise healthy peers. Sleep disturbances in medically ill children can be associated with sleep disorders, comorbid with acute and chronic conditions, or secondary to underlying disease-related mechanisms, treatment regimens, or hospitalization. Clinical management should include a multidisciplinary approach with particular emphasis on routine, regular sleep assessments and prevention of daytime consequences, and promotion of healthy sleep habits and health outcomes.

Predictors of low-income, obese mothers' use of healthful weight management behaviors

OBJECTIVE

To examine the influence of personal and environmental factors on healthful weight management behaviors mediated through self-efficacy among low-income obese mothers.

DESIGN

Cross-sectional design.

SETTING

Special Supplemental Nutrition Program for Women, Infants, and Children in Wisconsin.

PARTICIPANTS

Two hundred eighty-four obese mothers aged 18-34 years.

MAIN OUTCOME MEASURES

Personal factors (eg, eating low-fat/low-calorie food for weight management), environmental factors, self-efficacy, and weight management behaviors. Data were collected via self-administered written questionnaires.

ANALYSIS

Latent class cluster analysis and structural logistic regression.

RESULTS

Women who perceived more importance of eating low-fat/low-calorie food for weight management were more likely to practice multiple behavioral strategies to manage their weight (odds ratio = 0.37) than women who perceived less importance of eating low-fat/low-calorie food for weight management. Women who reported higher positive mood self-efficacy were more likely (odds ratio = 1.63) to practice multiple strategies to manage their weight than women who reported lower positive mood self-efficacy. Environmental factors did not predict use of multiple healthful weight management behaviors. No mediation effect was found.

CONCLUSIONS AND IMPLICATIONS

Stressing the importance of food choices and reinforcing learners' self-confidence to make healthful choices at parties and celebrations may be helpful ways to address common barriers to healthful weight management.

Emerging biobehavioral factors of fatigue in sickle cell disease

PURPOSE

The symptom most frequently associated with sickle cell disease (SCD) is pain, but recent research is beginning to indicate that fatigue as an increasingly important symptom of this disease upon which to focus research efforts. This article explores biological and behavioral factors that can potentially contribute to fatigue in SCD.

ORGANIZING FRAMEWORK

A biobehavioral framework guides this discussion of factors that may contribute to SCD fatigue.

FINDINGS

The pathophysiology of the disease process, such as the profound hemolytic anemia and unpredictable vasoocclusive crises, suggests that individuals with SCD are at risk for both acute and chronic fatigue. For example, hypoxemia can cause muscle weakness and produce oxidative stress, which, in turn, increases fatigue. Sickled erythrocytes disrupt the vascular endothelium and stimulate proinflammatory cytokines, which are linked to sleep disruptions. Pain, the most notorious symptom of SCD, has a complex and mechanistically poorly understood relationship with fatigue.

CONCLUSIONS

Little is known about the symptom of fatigue in SCD. Considering the biological and behavioral factors of SCD that could potentially contribute to fatigue, there is a great need for research on the nature and potential mechanisms of fatigue in SCD.

CLINICAL RELEVANCE

Fatigue in SCD may negatively affect quality of life. Understanding factors that may contribute to fatigue aids the clinician in identifying causes and determining treatment.

Patterns of fatigue in adolescents receiving chemotherapy

PURPOSE/OBJECTIVES

To describe patterns of fatigue in adolescents and the impact of fatigue during one month of chemotherapy, to explore variables that affect fatigue, and to explore the feasibility of collecting daily self-report data in this population.

DESIGN

Longitudinal, descriptive.

SETTING

Two pediatric oncology centers in central Virginia.

SAMPLE

20 adolescents with a variety of cancer diagnoses receiving chemotherapy.

METHODS

Adolescents described daily fatigue for one month using rating scales and qualitative diaries.

MAIN RESEARCH VARIABLES

Fatigue severity.

FINDINGS

Adolescents commonly reported a peak in fatigue in the days immediately following chemotherapy administration. The most common pattern for adolescents who received chemotherapy on a schedule every three to four weeks was a "declining rollercoaster" pattern, with fatigue severity alternating on a daily basis but gradually declining until chemotherapy was scheduled again. Adolescents who received chemotherapy weekly showed more frequent peaks and troughs (the "yo-yo" pattern) that did not diminish in severity over the weeks of the study. Adolescents associated fatigue with other symptoms, particularly sleep-wake disturbances, pain, and nausea, and frequently reported that fatigue interfered with daily activities.

CONCLUSIONS

Fatigue commonly bothers adolescents receiving chemotherapy, particularly in the days following chemotherapy administration and when other symptoms are present. Although fatigue interfered with the adolescents' abilities to maintain their usual lifestyles, many still participated in the typical activities of adolescence.

IMPLICATIONS FOR NURSING

Fatigue is a complex and dynamic symptom. Oncology clinicians and researchers should frequently assess fatigue in adolescents receiving chemotherapy and apply timely and tailored interventions to match the factors that contribute to fatigue and influence fatigue severity. Management of fatigue during treatment will help adolescents stay involved in age-related activities and meet developmental milestones.

Children and Adolescents with Cancer: experiences with Chemotherapy

This study aimed to comprehend chemotherapy from the perspective of children and adolescents with cancer. Ten children and adolescents between eight and 18 years of age, in different phases of chemotherapy, participated in this exploratory, qualitative study. Data collection was carried out through semi-structured interviews and analysis of the patients’ medical records. Analysis of the empirical material followed the content analysis technique. The study allowed the comprehension that, for the children and adolescents, chemotherapy is mainly remembered for its collateral effects and suffering. After the initial impact, mainly due to physical changes, preoccupations are related to disease recovery, i.e. a cure. Over time, they also mentioned that the disease was seen as something to be overcome and, due to the chemotherapy, likely to be the outcome.

Symptom clusters in children and adolescents receiving cisplatin, doxorubicin, or ifosfamide

PURPOSE/OBJECTIVES

To examine the influence of the proposed symptom cluster of fatigue, nausea and vomiting, and sleep disturbances on clinical outcomes defined as behavior changes, depression, and performance status in children and adolescents before and after receiving cisplatin, doxorubicin, or ifosfamide chemotherapy.

DESIGN

A prospective, descriptive, within-group, before-and-after-chemotherapy design was used.

SETTING

Two major childhood cancer treatment hospitals in the United States.

SAMPLE

67 patients aged 7-18 years who were receiving chemotherapy courses of cisplatin, doxorubicin, or ifosfamide.

METHODS

Fatigue, depression, behavior, and performance assessments were completed on the first day of cisplatin, doxorubicin, or ifosfamide therapy and one week later. Patients wore a wrist actigraph on the nondominant hand during the course of therapy and for 48 hours after discharge from the hospital. Nausea and vomiting were measured every 24 hours during the course of therapy and for 48 hours after discharge. A linear mixed model was used to evaluate the influence of the symptom cluster. Regression analysis was used to examine the associations between performance status and the symptom cluster. Principal component analysis with varimax rotation was used to produce the correlation of sleep symptoms.

MAIN RESEARCH VARIABLES

Fatigue, nausea and vomiting, sleep disturbances, behavior, depression, and performance.

FINDINGS

Adolescents with the cluster of increased fatigue and sleep disturbances experienced more depressive symptoms and behavior changes. Children with higher levels of fatigue had increased depressive symptoms. The more fatigue parents perceived in their children or adolescents, the more behavior and emotional difficulties were reported.

CONCLUSIONS

Fatigue, sleep disturbance, and nausea and vomiting, when clustered, impacted depressive symptoms and behavior changes in adolescents after chemotherapy. In children, fatigue alone impacted depressive symptoms and behavior changes.

IMPLICATIONS FOR NURSING

Symptom clusters can have a significant impact on children's and adolescents' quality of life during cancer treatment. Early recognition and intervention for these symptoms are an important nursing role.
