laboratory and ultrasongraphicc changes after endoscopical varices treatment

This is a feasibility study, to assess if thermal imaging and/or near infrared imaging will be useful in identifying changes in the peripheral circulation in patients with different stages of liver disease. The aim of this study is to use new and advanced thermal imaging techniques to identify changes in the peripheral circulation and hand temperature in patients with liver disease. These changes could be used as a non-invasive marker of the severity and progression of liver disease. Thermal imaging will also be used to assess the changes in the peripheral vasculature with the use of terlipressin, a drug used as treatment for specific complications of liver disease. Patients with acute or chronic liver disease from any aetiology will be recruited, along with patients without liver disease as healthy controls. Patients with disease or on drugs known to affect the peripheral vasculature will be excluded. All studies will be performed in a ward setting in the Royal Infirmary of Edinburgh. The subjects will be required for up to three sessions, each lasting 30 minutes. The session will involve static thermal images being taken, and video images of the hands warming up after being cooled for 30 seconds in water at a temperature of 7 degrees Celsius. If the patient is receiving terlipressin therapy, static images will be taken before, during and after terlipressin therapy.

The large share of chronic diseases correlated with an aging population calls to develop necessary coordination between the hospital and non-hospital (professional of the city, home ...) to create new complementarities. Since July 2013, the Nantes University Hospital experiences the establishment of a coordinator route patient in Gerontology. The evaluation program of the benefit of coordinating the course in elderly patients in health establishment (PROCOPES) must allow to prove the efficiency of the intervention of a coordinator route patient, following elderly patients in complex situations, both within the hospital and outside the hospital (home, nursing home,...). The objective of PROCOPES is to show the added value of an innovative position that can make the link between the hospital and the city on deemed complex situations.The pilot study results present a strong interest for health care settings, nursing home and in the world of research. It will also permit to have preliminary data for bigest studies.

In view of assessing the uphill walking capacity and to provide a functional stress test with better sensitivity the investigators need a short term functional stress test over the gold standard six minute walk test.... To demonstrate the significance of 3 minutes ramp walk test over 6 minutes walk test as a functional stress test. The investigators hypothesize that the investigators three minutes ramp walk test (3MRWT) will be superior to the existing six minutes level walk test (6MWT) in the measurement of functional capacity of post valve replacement patients.

To characterize the functional outcomes and prognostic factors for convulsive status epilepticus (SE) and to further develop and validate a simple and practicable scoring system for outcome prediction.

The purpose of this study is:1)to observe topological organization in brain structural and functional networks in cerebral white matter lesion patients and to evaluate the association between impairment of cognitive function and cerebral structural and functional networks in those patients;2)to indicate the role of genetic factors in the occurrence and prognosis of cerebral white matter lesions

The study will include a translation of the Central Sensisization Inventory into French and a cultural validation of the French version of the questionnaire (Reliability, discrimination and comparison with other questionnaires).

The purpose of this study is to determine the change in kidney function and blood pressure after gastric bypass versus conventional medical therapy in morbid obesity. The study mainly focus on glomerular filtration rate(GFR) with known relation to the renal function and 24 hours ambulatory blood pressure monitoring after intervention of gastric bypass or medical treatment.

In this trial, patients with cancer in the upper gastrointestinal canal who are going to receive first line palliative chemotherapy and patients with colorectal cancer who are going to receive second line palliative chemotherapy will be included. Participating patients will be randomized between early contact with a palliative care unit, or contact with a palliative care unit when needed. The objectives with the trial is to investigate if an early establishment with a palliative care unit will have a positive impact on the patients quality of life, this also applies for the nearest relative, survival, and if a difference in numbers of chemotherapy cycles can be detected.

Investigators will administer a brief, anonymous survey at the Texas Academy of Family Physicians (TAFP) annual Primary Care Summit to better understand the readiness of primary care physicians in Texas to implement lung cancer screening programs in their practice settings.
