Schizophrenia is a psychiatric pathology, which concerns around 1% of adult population. It is characterized by clinical symptoms combining positive and negative symptoms and thinking disorganization. Schizophrenia is also characterized by cognitive deficits, likely to play an important part in adaptation of these patients in their every-day life, and to affect their clinical symptomatology. Among them, there are deficits in sustained attention which are associated with a difficulty for these patients to maintain efficiently their cognitive activity on a source of stimulation or task. This basic attentional process is fundamental for the efficiency of the overall of cognitive processes, and so for all behaviors directed on an aim. The question of whether or not patients with schizophrenia have difficulty sustaining attention is of high relevance, in the sense that it could undermine performance on nearly any task and so provide a compelling causal explanation of many other impairments observed in these patients. Yet it has not been conclusively answered in over four decades of research. Consequently, the main objective of the protocol is to evaluate sustained attention abilities in schizophrenic patients and to better understand the specific functioning of cognitive and neural mechanisms underlying these abilities (attentional resources and cognitive control mechanisms).

The aim of this study is to determine whether the work environment influences the role perception of nurses in psychiatric wards. This will be a comparative study. Questionnaires will be distributed to nurses working in psychiatric wards in 10 medical centers in Israel.

Persons with coeliac disease treated with a gluten free diet will be asked to give blood for a new diagnostic blood test. In this test investigators will use multimerized HLA bound to different gliadin-peptides (tetramer) and with the help of a flow-cytometer identify (along with other relevant T-cell-markers) gluten specific T-cells. Investigators believe that these cells will be present in persons with coeliac disease regardless of gluten-intake. Investigators will compare their findings with two control groups; Persons on a gluten free diet where celiac disease is excluded (gluten sensitive group) and persons on a gluten containing diet (healthy control group). In the initial and main study investigators will look at HLA DQ2.5 individuals, which comprise >90% of all persons with coeliac disease.

The accuracy of sonographic prenatal detection of invasive placentation is unclear. The objective of this prospective, multicenter, observational study is to assess the performance of ultrasound for prenatal identification of invasive placentation in women with placenta previa. This study involves more than 25 hospitals in Italy.

The INSPYRE implant is a new range of shoulder hemi-arthroplasty device. It consists of a Pyrocarbon spherical interpositional implant and is indicated in primary surgery to relieve severe pain or significant disability caused by degenerative pathologies. The rotator cuff must be functional. The aim of this study is to prospectively collect data from consecutive series to implement a Post Marketing Surveillance plan.

The purpose of the study is to compare different approaches for the treatment of prosthetic joint revisions and to optimize the outcomes in patients with prosthetic joint infections (PJI) by improving the treatment concept of PJI.

Specially educated trainers will be responsible for colonoscopy training of junior doctors. The educated trainers will have attended seminars held by Valori et al. The following fast track colonoscopy training program for junior doctors will consist of: 1) Endoscopy simulation training and theory course 2) supervised and partly supervised lower endoscopy. 3) Directly observed practical skills according graded by MCSAT (Mayo Clinical Skills Assessment Tool) .

The knee prosthesis is a validated treatment for end-stage of knee osteoarthritis, and this intervention usually provides a significant improvement in the quality of life of patients. However, a significant percentage of patients (up to 30%) are disappointed with the outcome of the intervention. One hypothesis that could explain these poor results might be the poor positioning of implants. Individual cutting guides are produced after a CT scan response planning carried out according to the CT scan anatomy of each patient, and subsequently adapted to its real anatomy during surgery, thus theoretically better accuracy of the implementation over conventional techniques. It has been shown in the past that the navigation has been the gold standard in measuring the three-dimensional orientation of the implants during surgery, and this system is systematically used in the service for over 10 years.

The long term goal of this project is dual fold. First, the investigators wish to derive, validate and then test the impact of a clinical prediction rule to determine which patients who suffer from CLBP with degenerative changes of the lumbar spine and referred pain to the legs are likely to require surgery and have successful outcomes in the long term. Second, the investigators would like to establish robust methodology and statistical analysis guidelines for creating clinical prediction rules in physical therapy research. This observational cohort project is a first step towards those goals. Here the investigators specifically aim to identify personal, behavioral, psychological, morphological, and physical factors that can predict the need for surgery as well as level of participation restriction in patients who suffer from CLBP with degenerative conditions of the lumbar spine and referred pain to the legs. The investigators will also explore which parameters can predict success after 1 month, 6 and 12 months in patients who underwent decompression/fusion surgery.
