An increase in intracranial pressure (ICP) during migraine attacks is possible and could contribute to pain initiation and maintenance. From now on, it was not possible to measure ICP in a non-invasive way. The development of a new tool allows non-invasive self-measures of ICP variations. Thus, it is possible for the first time to look for such ICP variations during migraine attacks and to conclude if this mechanism is implied in the pathophysiology of migraine.

This non-interventional study aims to determine whether there is a correlation between the Fc receptor polymorphism (FcR) and the course of the disease following HIV infection.

Through exploring the specific genetic mutations in the upper gastrointestinal tract tumors with a family history and specific clinical pathological types，we establish a complete family and follow-up system，in order to improve the screening criteria of Chinese hereditary upper gastrointestinal tumors and carry on primary prevention of disease.

This is a multi-center, prospective, non-interventional study. Eligible newly diagnosed elderly multiple myeloma (MM) patients will receive comprehensive geriatric assessment (cGA) including ECOG scale, questionaires of ADL（activities of daily living), IADL(instrumental ADL),MNA-SF(mini-nutritional assessment), GDS(geriatric depression scale), MMSE(mini-mental state examination), SF-36 and CCI (charlson comorbidity index). Patients will get standard care for MM and receive the above assessments at baseline and after cycle 1, 4 and 12 for treating MM.Follow-up information and survival data of these MM patients would be collected. We would evaluate the cGA status of these newly diagnosed elderly MM patients and investigate the association of cGA parameters with patient's survival.

In the proposed study the investigators aim to clarify the relative contribution of these different mechanisms to the progression of atrial fibrillation (AF). Also the contribution of the individual genetic background will be investigated. Furthermore, the investigators aim to identify clinical parameters and biomarkers informing on the main mechanisms of AF progression in atrial tissue. For this purpose, in all included patients atrial biopsies will be taken during cardiac surgery.

Social deprivation during pregnancy is associated to adverse perinatal outcomes. However, prenatal screening of social deprivation by reliable measurement is not performed. Prevalence of social deprivation is yet underestimated during pregnancy and vulnerable women are not being provided optimal prenatal care. Our aim is to validate EPICES score during pregnancy.

Wear is the main reason for revision operations after joint arthroplasty. While the survival of modern implants is often longer than the expected life span in old patients, young patients (<60 years) have to expect at least one wear induced revision operation. The reason is the throughout all registries consistantly significantly reduced implant survival rates in young patients. In the swedish arthrplasty registry the 15 year survival for patients older than 75 years is 95 % and for those younger than 50 years is 75 %. This corresponds to a 5fold increased revision rate (5 % vs. 25 %) 15 years after implantation. This significant difference cannot be explained by the higher activity of younger patients alone. Patient specific factors, that modulate the biological reaction on wear particles, are therefore highly probable. These could explain the significant age dependency of implant survival. The main hypothesis of this study is therefore, that the biological reaction on wear particles depends on the patients age.
