Children undergoing cancer treatment are less active than healthy peers. Inactivity persists into survivorship, negatively influencing health and quality of life. Fatigue is one of the most prevalent symptoms during treatment yet children with increased physical activity (PA) have less fatigue. This pilot study evaluated the impact of coaching on PA and fatigue in children undergoing cancer treatment delivered by pediatric oncology nurse practitioners (NPs) during routine clinic visits. NPs used motivational interviewing during clinic visits to coach children and their families on strategies to increase PA at home. Self-report measures of PA and fatigue were completed at treatment months 2, 4, and 6. PA was also measured using actigraphy. Among 30 children ages 6 to 18 years, 7 had acute lymphoblastic leukemia (ALL), 11 had lymphoma, and 12 had solid tumors. Patterns of fatigue were different by disease group with trends to fatigue decreasing during treatment in the patients with ALL (p = .09) and lymphoma (p = .13) but increasing in those with solid tumors (p = .06). Self-report PA was unchanged. Actigraph measurements remained stable for the group. NPs reported time challenges in implementing coaching during the clinic visit and in providing coaching continuity. The intensive, repeating chemotherapy cycles in solid tumor treatment may contribute to increasing fatigue. Treatment intensity decreases during ALL and lymphoma treatment, which may allow for improvement in fatigue. Inactivity persisted during treatment but did not progress. Future research is needed to evaluate more "dose-intensive" PA interventions in larger samples of specific disease groups.

Young people with cancer are at increased risk of psychological difficulty; yet there is little research on their experiences of low mood or depressive symptoms to help inform treatment interventions. This qualitative study explored experiences and opinions of low mood or depression in young people with cancer, how their mood related to developmental challenges, strategies used to cope, and how services could improve support. Nineteen young people diagnosed and treated for cancer completed semistructured interviews. Transcripts were thematically analyzed using the framework approach, and analysis produced eight themes, organized into three domains: "A Harder Time of Life," "Interpersonal Impact of Cancer," and "Learning to Understand and Describe Low Mood," Participants interviewed experienced low mood during cancer and predominantly felt "low mood" was a helpful term to describe their emotions. There were similarities and variations in their reported mood compared with clinical depression. The developmental challenges of being a young person with cancer negatively affected their mood. Participants used a variety of different coping strategies to manage these challenges. Young people were clear that they would like others to help them understand negative emotions experienced through cancer are normal to feel and support for low mood to be accessible and available.

As the number of childhood cancer survivors (CCS) is increasing, it is imperative to understand the late effects of childhood cancer therapy to optimize their health and quality of life. Chemotherapy-induced peripheral neuropathy (CIPN) is an unpleasant effect of chemotherapy that affects the peripheral nervous system. This qualitative study uses narrative analysis with a phenomenological influence to understand the lived experience of CIPN among five CCS utilizing photo-elicitation. The lived experience of CIPN is characterized by "a condition of disconnection" with three subthemes: (1) disconnection between mind and body, (2) disconnection between anticipated potential and reality, and (3) disconnection between survivors and support. The condition of disconnection leads to a variety of negative physical and emotional performance outcomes. These findings support the need for refined clinical strategies for identifying this underappreciated condition and further development of interventions to "rebuild the connections" that CCS are lacking.

The bacterial periplasmic methionine-binding protein MetQ is involved in the import of methionine by the cognate MetNI methionine ATP binding cassette (ABC) transporter. The MetNIQ system is one of the few members of the ABC importer family that has been structurally characterized in multiple conformational states. Critical missing elements in the structural analysis of MetNIQ are the structure of the substrate-free form of MetQ, and detailing how MetQ binds multiple methionine derivatives, including both l- and d-methionine isomers. In this study, we report the structures of the Neisseria meningitides MetQ in substrate-free form and in complexes with l-methionine and with d-methionine, along with the associated binding constants determined by isothermal titration calorimetry. Structures of the substrate-free (N238A) and substrate-bound N. meningitides MetQ are related by a "Venus-fly trap" hinge-type movement of the two domains accompanying methionine binding and dissociation. l- and d-methionine bind to the same site on MetQ, and this study emphasizes the important role of asparagine 238 in ligand binding and affinity. A thermodynamic analysis demonstrates that ligand-free MetQ associates with the ATP-bound form of MetNI ∼40 times more tightly than does liganded MetQ, consistent with the necessity of dissociating methionine from MetQ for transport to occur.

For individuals with sickle cell disease (SCD), mild to moderate exercise is advised, but self-regulation of these intensities is difficult. To regulate intensity, one SCD recommendation is to stop exercising at the first perception of fatigue. However, perceived effort and affect (how one feels) are perceptual cues that are commonly used to guide exercise intensity. This study (a) examined perceived effort, affect, and fatigue in relation to metabolic state (gas exchange) in adolescents and young adults (AYAs) with SCD, (b) explored guidelines AYAs use to self-regulate exercise, and (c) compared perceived effort and affect at gas exchange threshold (GET) with healthy counterparts. Twenty-two AYAs with SCD completed an incremental cycle test. Perceived effort, affect, and fatigue were assessed every 2 minutes. A mixed-effects linear model was conducted to model changes in effort, affect, and fatigue across time. Mean scores of effort and affect at GET were compared with published data of healthy counterparts. Participants were queried about self-regulation exercise strategies. Findings indicated that both perceived fatigue and effort at GET was lower than expected. Perceived effort was lower (p < .0001), and perceived affect was significantly higher (p = .0009) than healthy counterparts. Interviews revealed that most participants (95%) do not stop exercising until fatigue is moderate to severe, and many (73%) do not stop until symptoms are severe (chest tightness, blurry vision). Nurses should review guidelines for safe exercise with AYAs with SCD. Exercise training may be beneficial to AYAs with SCD for learning how to interpret bodily responses to exercise to improve self-regulation.

Purpose: Reiki is a growing complementary therapy in pediatric oncology that needs evidence to become more credible among the health community. A within-subject design experiment was conducted to pilot testing the feasibility and efficacy of Reiki to provide pain relief among pediatric patients undergoing hematopoietic stem cell transplantation (HSCT). Method: Pediatric patients undergoing HSCT during the inpatient phase in the Stem Cell Transplantation Unit were eligible to participate to the pilot study. Short and medium effects were assessed investigating the increase or decrease of patient's pain during three specific time periods ("delta") of the day: morning of the Reiki session versus assessment before Reiki session (within subjects control period), assessment before Reiki session versus assessment after Reiki session (within subjects experimental period) and assessment after Reiki session versus morning the day after Reiki session (within subject follow-up period). The long-term effects were verified comparing the pain evolution in the day of the Reiki session with the following rest day. Results: The effect of 88 Reiki therapy sessions in nine patients (M_age = 12; Female = 61%) was analyzed following a short, medium, and long-term perspective. Repeated-measures analysis of variance revealed a significant difference among the three periods (F = 17,17 p < .0001): A decrease of the pain occurred in the experimental period in short and medium term, while in the follow-up period, the pain level remained stable. Conclusions: This study demonstrates the feasibility of using Reiki therapy in pediatric cancer patients undergoing HSCT. Furthermore, these findings evidence that trained pediatric oncology nurses can insert Reiki into their clinical practice as a valid instrument for diminishing suffering from cancer in childhood.

Children with a cancer diagnosis have risk factors leading to unique nutritional challenges. Malnutrition in this population is correlated with worse patient outcomes. Nurses are responsible for providing holistic care to their patients; however, the quality of nutritional assessments by pediatric oncology nurses is unknown. The purpose of this study was to investigate staff nurses' clinical decision making regarding nutritional assessment of children with cancer. A web-based survey composed of a demographic form, vignettes of patients with diverse nutritional status and the New General Self-Efficacy Scale, was distributed to members of the Association of Pediatric Hematology Oncology Nurses. Participants were also asked to rate their confidence in responses as well as select key nutritional cues. Nurses were significantly more likely to under-rate the nutritional status and select far fewer cues than the experts. Further research regarding nutritional assessment is warranted. Evidenced-based guidelines for nutritional assessment of children with cancer should be developed to ensure the highest quality of care is provided to this patient population.

Central line-associated bloodstream infections (CLABSIs) are still a major cause of morbidity and mortality in pediatric hematology-oncology patients in many countries. This cross-sectional study was a retrospective review of CLABSI in inpatient pediatric hematology-oncology cases with long-term central venous catheter at the Pediatric Hematology Department from January 2013 to June 2014. Characteristics of CLABSI events in pediatric patients with hematologic malignancies and related nonmalignant hematologic conditions are documented. CLABSI developed in 61.8% (n = 21) of the 34 hospitalized patients included in the study. The CLABSI rate was 7.8 per 1,000 inpatient central venous catheter days. Coagulase-negative staphylococci was the predominant pathogen in 47.6% of the patients with CLABSI. The high rate of CLABSI requires prevention strategies to reduce CLABSI immediately. This study provides guidance in prioritizing strategies for reducing rates of infection.

Professional certification validates nurses' knowledge and expertise in their specialty. In support of professional development, nursing excellence as a Magnet® designated hospital, and commitment to improve patient outcomes, increasing the number of certified pediatric hematology oncology nurses at Children's Hospital Los Angeles is a priority. Expert certified nurses and educators assessed current staff nurse perceptions of and motivations for becoming certified. A nurse survey was completed, and the results identified barriers to certification and the need for an onsite review course to encourage more nurses to take the Certified Pediatric Hematology Oncology Nurse (CPHON®) exam. The Oncology Nursing Certification Corporation (ONCC) CPHON® test blueprint guided the development of the Children's Hospital Los Angeles review course curriculum. Certified nurse experts volunteered as course instructors to present an overview of pediatric cancer, pediatric hematology, psychosocial review, chemotherapy and related medications, and long-term effects. In addition to course didactics, interactive learning sessions were included to allow participants to question, discuss, and apply new knowledge. Sample test questions were provided to each participant for independent study post-course attendance. Each participant completed course evaluations to measure the usefulness of the content, environment, and teaching methods. Since the implementation of this course, the overall number of certified hematology oncology nurses has increased by 15.3%.
