This project propose to measure plasma levels of apelin in wide population submitted to orthopedic surgery. Apelin could be involved in anti-inflammatory processes. Apelin levels before and after surgery correlated to postoperative cognitive disorders symptom measured by PET-Scan could be an important predictive or diagnostic marker to adapt therapeutic strategy to fight against postoperative cognitive disorders.', 'detailedDescription': 'It has been now clearly shown that important surgery with general anesthesia could be strongly associated to postoperative cognitive disorders few months after the intervention especially in elderlies. No strategy is really efficient to fight against this phenomenon that could lead to Alzheimer disease development. In order to prognosticate and characterize the potential risk to develop cognitive troubles after a surgery, this study propose to evaluate the potential predictive capacity of apelin in a cohort of young and old adult undergoing an orthopedic surgery. Apelin is a peptide involved in different physiological as well physiopathological pathways. This peptide, involved in osteogenesis and inflammatory processes, has also been described to be neuroprotective. Yet, hippocampic neuroinflammation has been related in case of postoperative cognitive disorders in human as well as in mice model of surgery. Taken together, these results seem to indicate that apelin could be a therapeutic target and be predictive of the postoperative cognitive disorders onset.\n\nThis study will measure plasma apelin levels in young and old adult one day before and after a programed orthopedic surgery. Moreover, to correlate apelin amounts with inflammation processes, protocol will quantify inflammatory cytokines in plasma (IL6, IL1, TNFα). These results will be compared to measures of brain b-amyloid deposit assessed by PET-Scan technology.\n\nThe follow-up of the patients will be done during 3 months in order to evaluate the postoperative cognitive disorders or the cognitive troubles associated to surgery (memory fail, decrease of cognitive reserve…).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['OLDER_ADULT'], 'minimumAge': '75 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients submitted to a programed orthopedic surgery\n* Patients with pre- and post-surgery check-up.\n\nExclusion Criteria:\n\n* Non programed orthopedic surgery (emergency)\n* Patients with sepsis\n* Patients submitted to orthopedic surgery but with ambulatory management.\n* Existence of justice backup, curators or supervision.\n* Absence of indication for a pre- or post-surgery check-up.'}, 'identificationModule': {'nctId': 'NCT02574234', 'acronym': 'APOCOGNIT', 'briefTitle': 'Influence of Apelin Levels on Postoperative Cognitive Disorders After Orthopedic Surgery in Elderlies (APOCOGNIT)', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital, Toulouse'}, 'officialTitle': 'Influence of Apelin Levels on Postoperative Cognitive Disorders After Orthopedic Surgery in Elderlies', 'orgStudyIdInfo': {'id': 'RC31/14/7313'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Patients with orthopedic surgery', 'description': 'Patients will be included in the consultation of anesthesia.
