A single-center cohort of patients with acute ischemic stroke and transient ischemic attack who admitted to the Severance hospital of Yonsei university and their long-term outcomes.

Outpatient midurethral surgery is a frequent surgery. It is performed either under general anesthesia or neuraxial anesthesia. A frequent complication is postoperative urinary retention requiring urinary catheterization, which implies a higher infectious risk. The investigators compared the complication rate after TVT surgery depending on the type of anesthesia.

Thyroid nodules are a very common clinical problem with prevalence of up to 68% in adults on high-resolution ultrasound .Ultrasound used in order to differentiate between benign and malignant lesion in the thyroid has shown sensitivity of 93.8% and specificity of 66% and US guided ( Fine needle aspiration ) FNA is known to be the test of choice in order to determine the nodules nature . Four to 6.5 % of all nodules are malignant .There are several guidelines that were suggested to help predict the risk stratification of thyroid nodules by ultrasound . The American Thyroid Association (ATA) is widely used as evaluation, clinical and ultrasound criteria for fine-needle aspiration biopsy and management of thyroid nodules. The recent ACR TIRADS is a reporting system for thyroid nodules on ultrasound proposed by the American College of Radiology (ACR) published april 2017 that uses a slightly different scoring system for recommendation for FNA of thyroid. The aim of this study is to validate TIRADS ACR 2017 risk stratification in the patient population in comparison to ATA risk stratification

The aim of this study is to validate and develop a new diagnostic and prognostic approach for assessment of liver function in children and adolescents with acute liver failure and chronic liver insufficiency. A carefully selected panel of functional and genomic tests along with diagnostic imaging and analysis of the microbiota will be performed in children and adolescents with acute liver failure and chronic liver insufficiency at Rigshospitalet. The tests will be performed in a serial manner in order to detect changes in outcomes. The study is an unblinded descriptive study, and approximately 20 patients with acute liver failure and 100 patients with chronic liver disease will be included in the project. This study will be the first of it's kind worldwide. The investigators expect the study to improve future diagnostic and prognostic accuracy and help the clinicians in identifying those patients in which the liver will regenerate itself, from those patients in which a liver transplantation will be lifesaving. Furthermore this study aims to help the clinicians in defining the optimal time for pediatric liver transplant in a narrow window of opportunity.

Lumbopelvic fixation is the treatment opation for spinopelvic dissociation. In our study we will compare unilateral versus bilateral lumbopelvic fixation as regarding functional outcomes by Majeed score along a period of 12vmonths as a primary measure and metal failure,skin condition and nonunion as secondaries.

The analysis of HIV resistance to antiretrovirals (Sanger sequencing on RNA) is difficult when the viral load is undetectable or during therapeutic breaks. In these situations, the ultra-deep sequencing (UDS) can be done on proviral DNA in order to improve characterization of archived resistant variants with may reflect past virological failures. This study is a cross-sectional study which will require only one additional tube which can be taken during a routine check-up as part of the usual follow-up of the individuals included.

There isn't specific Health related quality of life measure for children with DMD in French. The aim of this study is to validate the French version of the Pediatric Quality of Life Inventory 3.0 Duchenne Muscular Dystrophy module with a multicentric study. The investigators will evaluate the following psychometric properties : convergent validity, internal validity, inter-rater reliability. The investigators would like to be able to use this scientific tool in future clinical trials.

It is a prospective cohort study.The primiparas in six geographic regions of China are recruited to observe the natural recovery of pelvic floor muscle. The pelvic floor muscle function is evaluated at 6 weeks,3 months and 12 months after delivery.

Many studies describe the relationship between microbiota alteration and the occurrence of metabolic, alcoholic or inflammatory liver diseases. Nevertheless, the modifications of microbiota during liver transplantation (LT) as well as its implication are poorly studied. Similarly, only the intestinal microbiota is studied in this context, and no data are available on the biliary microbiota, even if it is known that bile microbiota can interfere with hepatobiliary diseases. This study proposes a clinical and biological in-depth follow-up with multiple sampling of liver transplanted patients to study biliary and intestinal microbiota alterations along LT, as well as bile acids metabolism in corresponding fluids. Indeed, in recipient samples as saliva, blood, urine, and feces can be taken before LT, and surgeons can easily perform bile sampling during LT. In donors all samples can be taken during liver removal. This offers the opportunity to have a microbiotic landscape of individuals without liver disease (donor), and patients suffering from a chronic liver disease or a liver cancer before and after transplantation. Also, in Grenoble University hospital, in case of biliary anastomotic incongruence, a biliary stent is placed during LT in 60% of recipients. This stent is removed by endoscopic retrograde cholangiopancreatography (ERCP) within 6 months after LT, offering a second opportunity to obtain bile samples in transplanted patients, after the early post-LT period. Patients who do not require a biliary stent will also be included for the study of secondary objectives, as intestinal microbiota is very poorly characterized in liver transplanted patients too. A portion of the patients without biliary stent, may also develop an anastomotic biliary stricture requiring an ERCP. If this ERCP is realized within the follow-up period of the study, the patient will also be included in the primary objective of the study. These multiple and sequential samples will allow a complete analysis of microbiota changes in LT patients and aim to answer to 3 questions: What are the modifications of intestinal and biliary microbiomes during LT? What is the influence of bile acids' composition on intestinal and biliary microbiota? What are the relationships between microbiome alterations and the emergence of LT complications?

The Tomey CASIA (Tomey Corporation, Nagoya, Japan) is a novel rapid imaging device that captures high-quality imaging of the entire anterior chamber of the eye over detailed imaging of a single section. In this prospective study, we want to investigate and compare the anatomical structure of the drainage angle of the eye in patients with different types glaucoma using Tomey machine. This study gives us a better understanding of the predictability, validity and accuracy of Tomey machine in the diagnosis of different types of glaucoma. Moreover, the data collected here will be used to create an artificial intelligence (AI) platform to screen certain type of glaucoma.
