ReviewInternational and national initiatives in biobanking.
Translational research and biobanking are "in", also in Flanders and in Belgium. In Flanders the Advice report 120 from the Flemish Council for Science and innovation, entitled "Extension of translational research in Flanders" paved the way for the Center for Medical Innovation. ⋯ However, the scientific interest in the human tissues is not new, at all. This text aims at giving an overview of the development and evolutions of "biobanking" initiatives.

ReviewEndocrine and metabolic disturbances in critical illness: relation to mechanisms of organ dysfunction and adverse outcome.
Critically ill patients face a high risk of death, which is mostly due to non-resolving multiple organ failure. The plethora of endocrine and metabolic disturbances that hallmark critical illness may play a key role. The major part of our research performed during the period 2004-2009 focused on the disturbed glucose metabolism that commonly develops during critical illness. ⋯ Avoiding hyperglycemia protected the endothelium and the mitochondria. In our animal model, nutritional interventions counteracted the hypercatabolic state of critical illness and insulin improved myocardial contractility, but only when normoglycemia was maintained. Interestingly, we identified the adipose tissue as a functional storage depot for toxic metabolites during critical illness.

ReviewCardiovascular characteristics in Marfan syndrome and their relation to the genotype.
Marfan syndrome (MFS) is a systemic disorder of connective tissue with autosomal dominant inheritance. The diagnosis of MFS is based on the identification of a combination of clinical manifestations in the ocular, musculoskeletal, and cardiovascular organ systems defined in the Ghent Nosology (De Paepe et al, 1996). Confirmation of the diagnosis in an individual requires the presence of major clinical manifestations in at least two organ systems associated with involvement of a third organ system. ⋯ In conclusion, we have refined diagnostic guidelines for the assessment of minor cardiovascular manifestations in MFS, shown that LV dysfunction is part of the cardiovascular spectrum and should be followed in the management of MFS patients, and demonstrated that aortic wave reflection is not elevated in MFS. In this work, we also investigated genotype/phenotype correlations, illustrated the marked (intrafamilial) variability in phenotypic expression of the condition, and the value of molecular testing in the diagnosis of MFS. Overall, this thesis nicely illustrates that close interaction and collaboration between cardiology and genetics is an added value to the study of disease pathogenesis of MFS and aortic aneurysms in general.

Determinants of variability in clearance of exogenous compounds in neonates.
Although the general principles of disposition and elimination of exogenous compounds apply in neonates, their specific characteristics warrant a tailored approach. Children display maturation in drug disposition, and these maturational changes are most prominent in the first year of life. Elimination clearance is mainly either through metabolic or renal elimination clearance. ⋯ These findings are illustrated by observations on amikacin, vancomycin and cefazolin disposition in perinatal life. These maturational changes all have impact on the pharmaco/toxicokinetics and -dynamics. We hereby would like to extent the adagio of Paracelsus that 'all is toxic, it only depends on the dose' by making the point that the 'patient' is also relevant.
