PROGRAMA DE INVESTIGACION

Descripción del programa de actividades de la investigación (Description of the research activity programme)

In the last four years, our network (Red SAMID), and previously most of its research groups, have been studying different aspects on two key areas on paediatric growth and development:

1) the factors causing brain injury in Childhood and thus affecting neurodevelopment, and
2) the early nutritional factors related to the latter development of the metabolic syndrome in preadolescent children.

 
Although these two topics might not seem to be related at first though, indeed there is a close links between them since both affect the growth and development processes from the foetus to the adolescence, areas of expertise of the research groups that are included in our research network.
 
1) Factors causing brain injury and thus affecting neurodevelopment (ND). The developing brain is especially vulnerable to many different insults that can induce impairment of its growth and development, and cause later in life neurodevelopment (ND) delays (cerebral palsy, mental retardation, language or learning and behavioural disorders...). Those insults to the brain occurred during the foetal, neonatal or early post-neonatal periods, and although the specific mechanisms are complex and vary, all are related to cerebral hypoxia and ischemia, and reperfusion (Hilario E. Current Pediatr Review 2006;2:131).
 
The aetiology of the ND disability is multiple, and the most frequent causes are different in the foetus -intrauterine growth restriction (IUGR), exposure to drugs and environmental toxic substances, malformations...)-, in the neonate -hypoxic-ischemic encephalopathy (HIE), infections, and cerebral lesions related to prematurity like severe Intraventricular haemorrhage (IVH), periventricular leukomalacia (PVL)-, or in the early infancy -infections, injuries, toxics, nutrition…- (Mwaniki MK et al. Lancet 2012;379:445).
 
Although advances in obstetrics and intensive care management have improved the survival of those target populations, impairment of ND has not decrease in the same magnitude. Thus, research on scientific aspects related to its causes and its health consequences, specially related to its prevention are much needed.
 
The different ND disorders produce great stress to parents, families and communities; consume large resources in the health and educational systems for follow-up, diagnosis, management and rehabilitation. Moreover, affected children might not be able to achieve and ability to self support and care for themselves and thus a full integration in society.
 
Although the incidence of some of these disorders has been specifically measured, the overall burden and long-term sequelae have not been capture in estimates of the total burden of disease measured by disability-free years, either in Spain or at an international level (Olusanya BO. PloS 2007;4:e84).
 
2) Early nutritional factors related to the latter development of the metabolic syndrome in preadolescent children. Childhood obesity is one of the main problems affecting children in developed countries and some developing ones, having a real epidemic proportion. In Spain, its prevalence has been increasing steadily, and is been estimated that affects to a 27% of children, one of the highest rates of all European countries (Lobstein T et al. Obes Rev 2003;4:195). The causes of obesity are multiple, been influenced by genetic and environmental factors, although over-feeding is the single most important one.
 
Obesity plays a key role on insulin resistance and the metabolic syndrome (MS) with severe cardiovascular  -hypertension- and metabolic risk factors (abdominal obesity, hyperglycemia due to type-2 diabetes, dyslipidemia) (Simmons R. Pediatr Clin N Amer 2009;56:449). However, only some obese susceptible individuals develop the MS, generally attributed to the interaction of genetic and environmental factors.
 
Many human and experimental studies have shown the relationship between low-birth-weight and obesity, insulin-resistance and the MS. Recently studies showed that fetal IUGR is an independent risk factor for insulin-resistance that it is amplified by obesity in childhood. In fact, those observations following the initial Barker-hypothesis (Baker DJ et al Lancet 1986;1; 1077) introduced the concept of early programming induced by altered intrauterine environment related to the maternal or fetal protein restrictions, and induces epigenetic  gene regulation, in the context of the developmental origins (foetal) of health and cardiovascular disease (Gluckman PD et al 2004;15;183). The concept of “developmental plasticity” is now used to describe the phenomena of generation of alternative genotypes forming a single genotype by the action of environmental factors during development (Gluckman PD et al. J Intern Med 2007;261;46). 
 
On the other hand, produced much efforts to develop effective preventive strategies, but unfortunately little has been achieved so far.
 
Our research network, by its multidisciplinary approach, is formed by researchers and clinicians in obstetrics, neonatal and childhood health specialists as well as some basic scientists, so it seems especially well equipped to undertake this program and fulfil the objectives of the proposed scientific program. For this reasons, as well as for the experience on working together toward a common goal in these fields for the last four years, we believe on the importance and dimension of our research program both, at a national and international levels, since we have human and equipment resources and expertise to study the topics proposed from the bench -animal models- to the bed side  -epidemiological and clinical trials-.
 
The state of the art in both Spain and in the international context is similar, as far as the clinical management of both cerebral damage and neurodevelopmental delays, and obesity and the MS. However, on the research aspects, in Spain there are no previous multidisciplinary research efforts in this topic, not only in Spain but there are some excellent studies on single aspects of the problems. The horizontal research approach -from the foetus to the adolescence- and the broad multidisciplinary groups involved, makes this  research program almost unique even at an international level. 
 
Hypothesis. There are perinatal and postnatal factors that lead to neurologic, nutritional and metabolic disorders from prenatal period to adolescence, that subsequently condition adult life health. The study of some of this factor might contribute to its prevention.
 
The Scientific Programme has its main strategic objective on the prevention and treatment of the perinatal and post-neonatal risk factors involved in the development of neurologic, nutritional and metabolic problems, from the foetal age to the adolescence.
 
More precisely, the operative scientific objectives are related to, 1) the factors causing brain injury and thus affecting neurodevelopment and 2) the early nutritional factors related to the latter development of the metabolic syndrome in preadolescent children.
 
To ensure the accomplishment of these two operative specific objectives, the research programme will be approached in several Work Packages (WP) appropriately linked and coordinated. Each WP will approach a specific objective that will be analysed by a few specific tasks. For each task, an outcome will be produced, that could be measurable to assure the correct progression of the program. Moreover, a timetable and a list of key milestones will be established for similar proposes.

The innovative aspects of this proposed research project are not only related to the horizontal and multidisciplinary approach to be implemented, but also in regard to the real possibilities for several technological advances to be transfer to industry and eventually to clinical use. Some groups have or are developing several devices or systems. In this regard, among others, a device to be used to prevent preterm birth has been developed and proven effective (Goya M et al. Lancet 2012, April 3, 2012 DOI:10.1016/S0140-6736(12)60030-0), prototypes of devices to deliver nebulised exogenous surfactant without need for intubation in preterm and term neonates with severe respiratory failure, and a multichannel integrated system to capture and analyse multiple electronic signals from brain, cardiovascular and pulmonary function, will be eventually used for monitoring and treatment decisions..
 
Furthermore, several of the research groups have register patents to support liquid ventilation (Alvarez et al.  No pat 2006/03096, Alvarez et al. No 1999/01420), that proves their ability to transfer rapidly research findings into technological innovations, assuring that it will also happen in this project.

SUMMARY

In summary, our network propose to study two hot topics in Paediatrics: 1) the factors causing brain injury, affecting neurodevelopment; and 2) the early nutritional factors related to the latter development of the metabolic syndrome in children. Our multidisciplinary research network has been formed by basic researchers and clinicians in obstetrics, neonatal and childhood health specialists to undertake the program and to fulfil the aims, with adequate human and equipment resources. The horizontal research approach (from foetus to adolescence) and the multidisciplinary groups (from bench to bed side), makes this research program almost unique even at international level. These topics will be approached by our research network in six work packages, which are our expertise area. Finally, we propose that the main outcomes obtained from the Work Plan will be freely presented to all Spanish health stakeholders, international scientist and the Spanish society as a whole for its dissemination and spreading.
