General objective: The EDONIS projects (PHRC national 2005) piloted by the Clermont-Ferrand Clinical Investigation Centre is a national multicentric epidemiological study whose primary objective is to know the prevalence of persistent pain at 3 and 6 months after surgery. This is the first prospective study of this size on chronic post-surgical pain which is a public health problem accounting for almost 15% of new consultations in specialist pain management institutions. Secondary objective: EDONIS also aims to identify pre-and peri-operative pain risk factors and to characterise its mechanisms with a focus on neuropathic factors. Eight types of conventional surgery were selected because (a) they are already known to induce persistent pain (thoracotomy, mastectomy, inguinal hernia repair), (b) they are frequently practised in France and chronic pain is an attribute (sternotomy, caesarean section, cholecystectomy, saphenectomy) or (c) surgery has a suspected risk of nerve injury (knee arthroscopy). There is also an associated ancillary genetic study.

General objective: to evaluate the impact (efficacy) of five different inpatient treatment modalities for anorexia nervosa. Individual global health outcome (physical, psychiatric, nutritional and social) will be measured on a short-term basis (on discharge), as well as hospital treatment meeting or exceeding statutory charges on a medium term basis (12 months), taking into account confounding factors and recognised prognostic factors. Global health is evaluated using the Morgan and Russell scale as well as secondary criteria for deteriorating health (see evaluation criteria methodology). Secondary objectives: - to determine predictive factors for failures in inpatient treatment, duration of hospitalisation, and treatment costs using clinical epidemiology methodology. - to begin a long-term prospective study to evaluate the psychological, physical, nutritional and social outcome of a homogeneous cohort of subjects suffering from severe anorexia nervosa. - two "ancillary" biological sub-projects: - to evaluate the development of depressive and anxiety symptoms in relation to changes in clinical nutritional status and serotonin markers - to evaluate cellular immunity development in relation to changes in clinical nutrition.

To assess the characteristics of patients admitted for acute or decompensated heart failure, their treatment course and practices regarding their treatment until discharge, and to measure the impact of these data on prognosis at 3 months.

To obtain epidemiological data, evaluate practices in terms of diagnostic and therapeutic treatment and to provide answers to clinicians' questions.

assess the current prevalence of addictive comorbidities in opioid-dependent subjects who have been receiving opioid substitution therapy (OST) for at least 6 months.
