This is a registry study on a multidimensional prediction model for rupture risk of unruptured intracranial aneurysms in China.

Inflammatory aortitis probably represents a heterogeneous group, and the clinical experience accumulated over the last ten years, shared by the experts of the subject, is that the initial clinical, biological or radiological characteristics should make it possible to differentiate them and dismember the Nosological field. This will be an essential first step before studying prognosis, risk factors, and therapeutic options. The search for diagnostic criteria on a large series, similar to the study of classification of vascularites of the ACR in 1990, should make it possible to homogenize the diagnoses for the different teams working on the subject, and to begin work Collaborations, which alone can improve patient care in the future.

Acute kidney injury (AKI) affects approximately 20% of hospitalized patients and up to 67% of those admitted to an intensive care unit (ICU), making it among the most common organ dysfunctions among the critically ill.Major adverse cardiac events (MACE) after non cardiac surgery are a leading cause of morbidity and mortality. The reported incidence of postoperative myocardial infarction (POMI) among patients undergoing noncardiac surgery is between 3% and 6%.The aim of this study is to Identify the impact of acute kidney injury on the development of myocardial injury after non cardiac surgery and to correlate it with other risk factors of for MINS.

The study will evaluate the benefit of early initiation of CRRT in the initial phase of severe sepsis in patients admitted to the ICU. Primary evaluated end-point is 28-day mortality. Secondarily evaluated end-point is length of ICU-stay, length of stay in hospital, duration of mechanical ventilation. There are two groups. One group of participants with early CRRT initiation and another group with late CRRT initiation. Reference group no CRRT.

Sleep-disordered breathing (SDB) describes a group of disorders in which partial or complete cessation of breathing occurs many times throughout the night, resulting in daytime sleepiness or fatigue that interferes with a person's ability to function and reduces quality of life. Transplantation has become an important treatment modality for end-stage organ failure. Transplant recipients are now living longer and, hence, develop chronic adverse medical conditions. Furthermore, transplantation is associated with weight gain. Despite the high prevalence of poor sleep and cardiovascular conditions among transplant patients, SDB is not well studied in these patients.

Ankle osteoarthritis is a progressive degenerative joint disease that is characterized by severe pain, loss of autonomy, diminished health-related quality of life, functional disability and diminished physical ability to fulfill occupational duties of life in its end-stage. Current surgical treatments for ankle osteoarthritis are ankle arthrodesis and total ankle replacement. Despite the good pain relief provided by these procedures, patients are still experiencing post-operatively important functional limitations in their activities of the daily living which affect their independency and quality of life. In order to remain capable of performing primary activities of the daily living, those patients have to make functional compensatory adaptations in the ipsilateral adjacent joints that will cause additional degenerative joint disease in those joints. Currently, the outcome of foot and ankle surgery is primarily based on clinical, radiographic and questionnaire outcomes. However, these outcome measures have been criticized for not being sensitive enough to detect clinically meaningful change in foot function. To tackle these shortcomings, an advanced clinical examination platform integrating pressure-force-kinematic measurement devices was developed and showed its clinical value for the detection of intrinsic foot mobility impairments. Surprisingly, up-to-now, no study has included this integrated use of three-dimensional multi-segment foot models, plantar pressure platform and a force platform to report on the functional outcome of an ankle arthrodesis or a total ankle replacement. Therefore, a multi-centre study will be conducted with two foot & ankle surgery centres. Both centres are equipped with the same advanced clinical examination platform. It is believed that proposed approach has the potential to provide further insight in the true functional changes related to ankle arthrodesis and total ankle replacement. This may in turn result in improved rehabilitation, less risk for post-operative complications, earlier discharge and quicker resumption of normal activities of the daily living, which would make ankle arthrodesis and total ankle replacement more cost-efficient and could potentially affect thousands of patients each year. Therefore, the hypotheses of the present study are: Hypothesis (H1): Subjects with an ankle arthrodesis require a greater reorganization of foot and lower limb kinematic and kinetic patterns to respond to mechanical requirements of level walking compared to subjects with a total ankle replacement. Null hypothesis (H0): Subjects with an ankle arthrodesis do not require a greater reorganization of foot and lower limb kinematic and kinetic patterns to respond to mechanical requirements of level walking compared to subjects with a total ankle replacement.

Perioperative anaphylactic reactions are immediate, hypersensitive reactions that are potentially life-threatening resulting from a sudden release of mediators from mast cells and basophiles. Which is due to either immune (IgE or non-IgE mediated) or non-immune mechanisms. Pseudo-allergic are defined as those reactions that produce the same clinical symptoms with anaphylaxis but are not IgE mediated, occur through a direct nonimmune-mediated release of mediators from mast cells and/or basophils or result from direct activation.so pseudo-allergic reactions do not require previous contact with the substance. Recent studies have shown that a mast-cell-specific receptor,G-protein-coupled receptor MRGPRX2,is crucial for pseudo-allergic drug reactions.in this study. In the study, we will examine the MRGPRX2 gene in patients with pseudo-allergic reactions during anesthesia, aiming at clarifying the relationship between pseudo-allergic reactions and MRGPRX2 gene.

The objective is to determine the incidence of thrombosis on central venous catheters in patients hospitalized in a surgical critical care unit, in the immediate postoperative period of urological or digestive carcinological surgery, and receiving parenteral nutrition.

The purpose of this registry is to collect uniform genomics-centered data on patients with nodular thyroid disease and cancer in a prospective fashion. After initial clinical evaluation patients with thyroid nodules will undergo standard ultrasonographic evaluation and a needle biopsy of the thyroid (fine needle aspiration (FNA) or core biopsy) as clinically indicated. Biopsy samples will be evaluated cyto-pathologically. A molecular/genomic profiling will be obtained using Thyroseq v2 test. Surgical treatment will be performed as per clinically determined indications. Standard surgical pathology will be processed and reported per the institutional policy and procedures. A molecular/genomic profiling will be obtained using Thyroseq v2 on the surgical specimen. All patients undergoing thyroid nodule work-up may be enrolled. The registry will collect patient demographic and clinical data, cytopathology reports, and surgical pathology reports and slides (if/when a review is required).

The investigators wish to characterize alterations in the architecture and function of immune cells in patients with a primary immunodeficiency that also develop inflammatory bowel disease. In addition, The investigators' goal is to characterize the microbiome of these patients, in order to determine whether specific microbial alterations are related to inflammation.
