Cancer-related fatigue (CRF) is the most stressful and prevalent symptom in paediatric oncology patients. This integrative review aimed to identify, analyse and synthesise the evidence of non-pharmacological intervention studies to manage fatigue and psychological stress in a paediatric population with cancer. Eight electronic databases were used for the search: PubMed, Web of Science, CINAHL, LILACS, EMBASE, SCOPUS, PsycINFO and the Cochrane Library. Initially, 273 articles were found; after the exclusion of repeated articles, reading of the titles, abstracts and the full articles, a final sample of nine articles was obtained. The articles were grouped into five categories: physical exercise, healing touch, music therapy, therapeutic massage, nursing interventions and health education. Among the nine studies, six showed statistical significance regarding the fatigue and/or stress levels, showing that the use of the interventions led to symptoms decrease. The most frequently tested intervention was programmed physical exercises. It is suggested that these interventions are complementary to conventional treatment and that their use can indicate an improvement in CRF and psychological stress.
Objective To evaluate evidence from randomised controlled trials and non-randomised controlled trials on the effectiveness of hospital clowns for a range of symptom clusters in children and adolescents admitted to hospital with acute and chronic conditions. Design Systematic review of randomised and non-randomised controlled trials. Data sources Medline, ISI of Knowledge, Cochrane Central Register of Controlled Trials, Science Direct, Scopus, American Psychological Association PsycINFO, Cumulative Index to Nursing and Allied Health Literature, and Latin American and Caribbean Health Sciences Literature. Study selection Randomised and non-randomised controlled trials were peer reviewed using the following eligibility criteria: children and adolescents who were admitted to hospital for acute conditions or chronic disorders, studies comparing use of hospital clowns with standard care, and studies evaluating the effect of hospital clowns on symptom management of inpatient children and adolescents as a primary outcome. Data extraction and synthesis Two investigators independently screened studies, extracted data, and appraised the risk of bias. Methodological appraisal was assessed by two investigators independently using the Jadad scale, the revised Cochrane risk-of-bias tool for randomised controlled trials (RoB 2), and the risk of bias in non-randomised studies (ROBINS-I) tool for non-randomised controlled trials. Results 24 studies (n=1612) met the inclusion criteria for data extraction and analysis. Most studies were randomised controlled trials (n=13). Anxiety was the most frequently analysed symptom (n=13), followed by pain (n=9), psychological and emotional responses and perceived wellbeing (n=4), stress (n=4), cancer related fatigue (n=3), and crying (n=2). Five studies used biomarkers, mainly cortisol, to assess stress or fatigue outcome following hospital clowns. Most of the randomised controlled trials (n=11; 85%) were rated as showing some concerns, and two trials were rated with a high risk of bias. Most non-randomised controlled trials (n=6; 55%) were rated with a moderate risk of bias according to ROBINS-I tool. Studies showed that children and adolescents who were in the presence of hospital clowns, either with or without a parent present, reported significantly less anxiety during a range of medical procedures, as well as improved psychological adjustment (P<0.05). Three studies that evaluated chronic conditions showed favourable results for the intervention of hospital clowns with significant reduction in stress, fatigue, pain, and distress (P<0.05). Conclusions These findings suggest that the presence of hospital clowns during medical procedures, induction of anaesthesia in the preoperative room, and as part of routine care for chronic conditions might be a beneficial strategy to manage some symptom clusters. Furthermore, hospital clowns might help improve psychological wellbeing in admitted children and adolescents with acute and chronic disorders, compared with those who received only standard care.

In recent years, translational research (TR) has become a new approach for bridging basic research and clinical practice. This article examines studies in which the authors used TR to learn more about the underlying causes of selected symptoms, and to discuss these results in the context of cancer nursing and symptom management. A literature review was undertaken, plus critical analysis of the authors. TR conducted by cancer nursing scholars has been relatively limited in the past, but is becoming more common as nurses complete additional academic work in the basic sciences and develop research teams with colleagues of those areas of knowledge. The goal in these studies is to show how a set of variables explains differential interventional effects. The availability of TR provides new evidence for the management of symptoms experienced by individuals with cancer, which could lead to improvements in the care of cancer patients across the world.
Galectin-3 (Gal 3) is a glycan-binding protein that can be secreted by activated macrophages and mast cells at inflammation sites and plays an important role in inflammatory diseases caused by Bacteria and their products, such as lipopolysaccharides (LPS). Although it is well established that Gal 3 can interact with LPS, the pathophysiological importance of LPS/Gal 3 interactions is not fully understood. Data presented herein demonstrate for the first time that the interaction of Gal 3, either via its carbohydrate binding C-terminal domain or via its N-terminal part, with LPS from different bacterial strains, enhances the LPS-mediated neutrophil activation in vitro. Gal 3 allowed low LPS concentrations (1 µg/mL without serum, 1 ng/mL with serum) to upregulate CD11b expression and reactive oxygen species (ROS) generation on human neutrophils in vitro and drastically enhanced the binding efficiency of LPS to the neutrophil surface. These effects required LPS preincubation with Gal 3, before neutrophil stimulation and involved specific Gal 3/LPS interaction. A C-terminal Gal-3 fragment, which retains the lectin domain but lacks the N-terminal part, was still able to bind both to Escherichia coli LPS and to neutrophils, but had lost the ability to enhance neutrophil response to LPS. This result emphasizes the importance of an N-terminus-mediated Gal 3 oligomerization induced by its interaction with LPS. Finally we demonstrated that Balb/C mice were more susceptible to LPS-mediated shock when LPS was pretreated with Gal 3. Altogether, these results suggest that multimeric interactions between Gal 3 oligomers and LPS potentiate its pro-inflammatory effects on neutrophils.
Background Clown intervention has been shown to enhance emotional and behavioral processes, but few studies have comprehensively examined the effectiveness of this practice using biomarkers. Objective The aim of this study was to evaluate the effect of a clown intervention on the levels of psychological stress and cancer-related fatigue in pediatric patients with cancer undergoing chemotherapy. Methods Sixteen patients who met all criteria from a pediatric oncology inpatient unit in a Brazilian comprehensive cancer care hospital participated in this quasi-experimental study. Eight saliva samples were collected, comprising 4 at baseline and 4 after clown intervention (+1, +4, +9, and +13 hours after awakening). Salivary cortisol and α-amylase levels were determined using high-sensitivity enzyme-linked immunosorbent assay kits. Stress and fatigue were measured by the Child Stress Scale-ESI and the PedsQL Multidimensional Fatigue Scale, respectively. Relationships among stress, fatigue, and biomarker levels were investigated using nonparametric statistics. Results In comparison with baseline measurements, the total psychological stress and fatigue levels improved after the clown intervention at the collection time point +4 hours (P = .003 and P = .04, respectively). Salivary cortisol showed a significant decrease after clown intervention at the collection time points +1, +9, and +13 hours (P < .05); however, α-amylase levels remained unchanged. Conclusion These findings provide preliminary evidence that clown intervention merits further study as a way to reduce stress and fatigue in pediatric cancer inpatients, and that self-report and biomarker measures are feasible to collect in this patient group. Implications for Practice Clown intervention as a nonpharmacological intervention may improve stress and fatigue levels in pediatric inpatients with cancer undergoing chemotherapy.
It is essential to update knowledge on this subject and discuss the theories that support research and the clinical practice of symptom management in order to better qualify nursing care.
