Une vue globale du secteur ambulatoire: étude structurelle et fonctionnelle dans les cantons de Vaud et Fribourg. [A general view of the ambulatory care sector: Structural and functional study in the cantons of Vaud and Fribourg].

The project "Quantification and qualification of ambulatory health care", financed by the Swiss National Science Foundation and covering the Cantons of Vaud and Fribourg, has two main goals: --a structural study of the elements of the ambulatory care sector. This is done through inventories of the professions concerned (physicians, public health nurses, physiotherapists, pharmacists, medical laboratories), allowing to better characterize the "offer". This inventory work includes the collect and analysis of existing statistical data as well as surveys, by questionnaires sent (from September 1980) to the different professions and by interviews. --a functional study, inspired from the US National Ambulatory Medical Care Survey and from similar studies elsewhere, in order to investigate the modes of practice of various providers, with particular regard to interprofessional collaboration (through studying referrals from the ones to the others). The first months of the project have been used for a methodological research in this regard, centered on the use of systems analysis, and for the elaboration of adequate instruments.

The 2013 Arvid Wretlind lecture: evolving concepts in parenteral nutrition.

Fifty years after the clinical introduction of total parenteral nutrition (TPN) the Arvid Wretlind lecture is an opportunity to critically analyse the evolution and changes that have marked its development and clinical use. The standard crystalline amino acid solutions, while devoid of side effects, remain incomplete regarding their composition (e.g. glutamine). Lipid emulsions have evolved tremendously and are now included in bi- and tri-compartmental feeding bags enabling a true "total" PN provided daily micronutrients are prescribed. The question of exact individual energy, macro- and micro-nutrient requirements is still unsolved. Many complications attributed to TPN are in fact the consequence of under- or over-feeding: the historical hyperalimentation concept is the main cause, along with the use of fixed weight based predictive equations (incorrect in 70% of the critically ill patients). In the late 80's many complications (hyperglycemia, sepsis, fatty liver, exacerbation of inflammation, mortality) were attributed to TPN leading to its near abandon in favour of enteral nutrition (EN). Enteral feeding, although desirable for many reasons, is difficult causing a worldwide recurrence of malnutrition by insufficient feed delivery. TPN indications have evolved towards its use either alone or in combination with EN: several controversial trials published 2011-13 have investigated TPN timing, an issue which is not yet resolved. The initiation time varies according to the country between admission (Australia and Israel), day 4 (Swiss) and day 7 (Belgium, USA). The most important issue may prove to be and individualized and time dependent prescription of feeding route, energy and substrates.
