ABSTRACT
BACKGROUND: New approaches on paediatric cancer treatment aim to maintain long-term health. As a result of radiotherapy, chemotherapy or surgery, paediatric cancer survivors tend to suffer from any chronic health condition. Endocrine dysfunction represents one of the most common issues and affects bone health. Exercise is key for bone mass accrual during growth, specifically plyometric jump training. The iBoneFIT study will investigate the effect of a 9-month online exercise programme on bone health in paediatric cancer survivors. This study will also examine the effect of the intervention on body composition, physical fitness, physical activity, calcium intake, vitamin D, blood samples quality of life and mental health. METHODS: A minimum of 116 participants aged 6 to 18 years will be randomized into an intervention (n = 58) or control group (n = 58). The intervention group will receive an online exercise programme and diet counselling on calcium and vitamin D. In addition, five behaviour change techniques and a gamification design will be implemented in order to increase the interest of this non-game programme. The control group will only receive diet counselling. Participants will be assessed on 3 occasions: 1) at baseline; 2) after the 9 months of the intervention; 3) 4 months following the intervention. The primary outcome will be determined by dual energy X-ray absorptiometry (DXA) and the hip structural analysis, trabecular bone score and 3D-DXA softwares. Secondary outcomes will include anthropometry, body composition, physical fitness, physical activity, calcium and vitamin D intake, blood samples, quality of life and mental health. DISCUSSION: Whether a simple, feasible and short in duration exercise programme can improve bone health has not been examined in paediatric cancer survivors. This article describes the design, rationale and methods of a study intended to test the effect of a rigorous online exercise programme on bone health in paediatric cancer survivors. If successful, the iBoneFIT study will contribute to decrease chronic health conditions in this population and will have a positive impact in the society.

Introducción. La leucemia es el cáncer más frecuente en edad pediátrica. Su tasa de curación es del 80% con quimioterapia intensiva, que mejora la supervivencia, pero que también aumenta la frecuencia de efectos adversos, incluyendo los neurológicos. Objetivos. Describir la frecuencia y características de las complicaciones neurológicas (CN) en pacientes con leucemia aguda linfoide (LAL) y leucemia aguda mieloide (LAM), e identificar los factores asociados a su presencia, la tasa de morbilidad neurológica y la supervivencia. Pacientes y métodos. Estudio retrospectivo de las CN presentes durante el tratamiento y seguimiento de los pacientes con LAL y LAM entre 1997 y 2012 por la unidad de oncohematología infantil. Variables analizadas: datos demográficos, diagnóstico oncológico, tratamiento y CN. Resultados. Se incluyó un total de 157 pacientes, 145 sin infiltración de sistema nervioso central al diagnóstico y ocho con infiltración (tasa de CN del 14 y 12%, respectivamente). Las CN más frecuentes fueron: neuropatías (31%), alteración del nivel de conciencia (27%), convulsiones (22%) y cefalea (12%). Un 40% de los pacientes con CN ha presentado secuelas, pero ninguno ha fallecido como consecuencia de la CN. Se han detectado más CN en el grupo de edad menor de 6 años con LAL de alto grado, en niveles de gravedad más altos y en pacientes que habían recibido trasplante de precursores hematopoyéticos, todas ellas con diferencias estadísticamente significativas. Conclusiones. Las complicaciones neurológicas son frecuentes en los pacientes con leucemia aguda, en especial en aquellos con estadio de riesgo alto (sobre todo si son menores de 6 años) y trasplante de precursores hematopoyéticos. La mortalidad asociada es baja (AU)
Introduction. Leukaemia is the most frequent type of cancer at the paediatric age. The cure rate is 80% with intensive chemotherapy, which improves survival but also often increases the frequency of adverse side effects, including those of a neurological nature. Aims. To describe the frequency and characteristics of the neurological complications (NC) in patients with acute lymphoid leukaemia (ALL) and acute myeloid leukaemia (AML), as well as to identify factors associated to their presence, neurological morbidity and survival rate. Patients and methods. A retrospective study was conducted of the NC present in patients with ALL and AML between 1997 and 2012 treated and followed up by the child onco-haematology unit. The following variables were analysed: demographic data, oncological diagnosis, treatment and NC. Results. Altogether 157 patients were included, 145 without infiltration of the central nervous system at diagnosis and eight with infiltration (rate of NC of 14% and 12%, respectively). The most frequent NC were: neuropathies (31%), altered levels of consciousness (27%), convulsions (22%) and headache (12%). Forty per cent of the patients with NC presented sequelae but none of them died as a consequence of the NC. More NC were detected in the age group of children aged under 6 years with high-degree ALL, at higher levels of severity and in patients who had received a haematopoietic stem-cell transplant, all of them with statistically significant differences. Conclusions. Neurological complications are common in patients with acute leukaemia, especially in those at a high-risk stage (above all if they are under the age of 6 years) and with haematopoietic stem-cell transplant. The associated mortality rate is low (AU)
