Older adult participants will complete eight immersive virtual reality (VR) sessions with the researcher, within five weeks (no more than two sessions per week may be scheduled). The screening process and assessment measures are not included in the five weeks of virtual reality. Sessions will consist of 30 minutes of use of the virtual reality goggles. During the virtual reality sessions, participants will select from a list of Oculus Go apps related to their self-identified occupational performance issues. Participants are expected to complete the session while seated with the VR set secured on their head.

Gastroesophageal varices occurs in approximately half of the patients with liver cirrhosis. Variceal bleeding is the most common lethal complication directly from cirrhotic portal hypertension. The golden standard for diagnosing gastroesophageal varices and evaluating the risk of variceal bleeding is the esophagogastroduodenoscopy. According to the Baveno VI consensus, for those with high-risk varices (varies needing treatment), either non-selective beta blockers or endoscopic band ligation is recommended for the prevention of the first variceal bleeding. However, the invasiveness and uncomfortableness during the esophagogastroduodenoscopy procedure has hindered its routine use in clinical practice, especially in compensated cirrhotic patients. The important role of transient elastography for defining the presence of high-risk varices was highlighted in the Baveno VI consensus workshop that cirrhotic patients with a liver stiffness measurement (LSM) of less than 20 kPa and a platelet count of greater than 150,000/μL can avoid screening endoscopy. In addition, transient elastography-based models (e.g. LSM combined with platelet count, liver stiffness spleen diameter-to-platelet score) were shown to have potentials in distinguish the absence of high-risk gastroesophageal varices. However, this cutoff value of LSM was validated mainly in cohorts with alcoholic or hepatitis C virus dominated cirrhosis. The unmet need is a precise cutoff to rule out high-risk varices in hepatitis B virus dominated cirrhosis, which is an outstanding issue in Asia-Pacific population. FibroTouch (Hisky Medical Technologies Co. Ltd, Wuxi, China) is a new-generation of transient elastography based on a two-dimensional image-guided system to ensure the precise orientation. In the present study, the investigators aim to conduct an international prospective diagnostic trial with 16 sites to develop and validate the diagnostic performance of FibroTouch-based models for assessing risk of gastroesophageal varices bleeding in compensated cirrhosis.

Sustained, monomorphic ventricular tachycardia (VT) is most commonly encountered in patients with structural heart disease, usually with ischemic aetiology. It has been proven that repeated episodes of sustained VT contribute to the mortality of patients with structural heart disease. These patients are usually implanted with implantable cardioverter defibrillator without (ICD) or with cardiac resynchronisation therapy (CRT-D). According to the current guidelines 3D mapping with radiofrequency (RF) ablation of the tachycardia substrate is an established therapeutic option. As part of the clinical follow-up of patients implanted with cardiac implantable electronic devices (CIED), CIED function parameters are monitored every 6 months, which is always done before and after any procedure involving RF ablation. Furthermore, a transient drop of R wave sensing has been demonstrated after the atrioventricular (AV) node ablation in patients with single-chamber pacemakers and fast atrial fibrillation. The aim of this study is to assess the change in R wave sensing after the RF ablation of VT substrate. This study will be performed as a clinical, prospective, multi-centre, observational cohort study with a structured follow-up period of 12 months. All consecutive patients with sustained VT implanted with ICD or CRT-D undergoing RF ablation procedure of myocardial substrate, who are able to understand and sign informed consent, will be enrolled. Primary objective is a R wave sensing drop > 30% after VT substrate ablation procedure. Recruiting should not exceed 12 months with the minimal follow-up period of 12 months (24 months in total). Standardized statistical methods and test will be done using SPSS Software Version 22.0 or newer. This unique study offers the possibility to show the impact of RF ablation on short-term and long-term R wave sensing change assessed by ICD or CRT-D's ventricle electrode in patients with sustained VT and structural heart disease undergoing ablation procedure. This observational data is needed to further refine the treatment of these patients and to prevent possible ICD/CRT-D dysfunction which could endanger this patient population.

The study of implantation potential of the embryo stay a priority in In Vitro Fertilization (IVF). Indeed, the selection of embryos to transfer is actually based in routine check on morphologic criteria, approved by literature but not perfect. Implantation's markers identification, allowing to choose the embryo(s) to transfer and then decrease pregnancy failure, represent a major issue in IVF, not any biomarker being approved yet. Among factors regulating embryonic implantation, investigators have recently proposed soluble CD146, coming from proteolytic cleavage of the CD146 membrane, angiogenic bond molecule. In a monocentric study about 222 transferred embryos at the end of IVF try, investigators showed that the sCD146 dose in the embryonic culture environment reflected the implantation ability of embryo, a high rate showing a low implantation potential and this independently of the embryonic quality. A multicentric prospective study is now required to confirm the utility of this dosage in clinical practice. Primary objective : Compared 2 frozen embryo transfer (FET) strategies in terms of implantation efficiency, according to choice method of embryo to be transferred : Group A : Standard strategy : Depending on embryonic quality according to criteria currently selected. Group B : Experimental strategy : Association of embryonic quality according to criteria currently selected and of sCD146 rate. Expected Results : Demonstrate a beginning pregnancy test significantly superior in Group B compared to Group A. Confirmed that sCD146 is an independent biomarker of morphologic embryonic quality (actual selection criteria) and represent a complementary criteria to choose embryos to transfer. Methodology : - Multicentric prospective study with 2 groups of Frozen Embryo Transfer (FET); The calculation of the number of staff required includes 151 couples per group. For this will be include for 24 months, couples benefiting of freezing at least one of the two embryos and transfer of only one FET. Test the same day of environment freezing where frozen embryos were cultivated. sCD146 dosage by ELISA technic (Enzyme Linked ImmunoSorbent Assay) in thus culture environment before FET. Implantation potential analyze of each transfer embryo (FET) according to sCD146 rate. Following of the FET future(pregnancy, childbirth) : maximum 9 months after attempt to each included couple.

Over 63-90% of patients develop peritoneal adhesions after abdominal or pelvic surgery. Which makes it the most common complication after abdominal or pelvic surgery. Adhesions comprise a lifelong risk of adhesion related complications.The most frequent emergency complication of adhesion is an episode of adhesive small bowel obstruction (ASBO). Over 1 in 5 patients experiences at least 1 episode of ASBO in the 10 years following initial abdominal surgery. Despite the high incidence of ASBO, diagnosis and treatment of an episode of ASBO varies greatly between hospitals and even between doctors. Until now, optimal treatment patterns are unknown. The aim of this study is mapping of care for patients with a suspected episode of ASBO. With the collected data new hypothesis will be generated for the ideal diagnostic and therapeutic workflow for patients with a suspicion of an episode of ASBO.

Hysteroscopy has now become a gold-standard technique carried out for uterine cavity assessment in infertile women. Apart from direct visualizing of the endometrium by the naked eye, pathologies missed by other modalities of investigation can be picked up and managed appropriately. Unfortunately, the procedure itself is not free from complications e.g. perforation, cervical laceration, bleeding, limited access in cases of cervical stenosis and considered as an invasive procedure. Two-dimensional transvaginal ultrasonography (2D-TVS)and Three-dimensional TVS (3D-TVS) are non-invasive methods for evaluating the uterine cavity. The3D-TVS is superior to 2D-TVS in identifying uterine cavity abnormalities due to its ability to obtain a view of three different planes of the uterus, which could be used to locate the position of intracavitary pathology. Reports vary regarding the diagnostic accuracy of 3D-TVS that was reported to have 41.3-81.5% sensitivity and 94.6-98.7% specificity. So it became clear that 3D-TVS is a non-invasive and safe diagnostic tool for evaluation of the uterine cavity abnormalities but its sensitivity, specificity and accuracy still a matter of debate and warrants more evaluation.
