Comparison of safety and long-term effects of BioMimeTM stent and Ultimaster® stent with Xience® stent
Congenital lung anomalies include different pathologies such as congenital cystic adenomatoid malformation, pulmonary sequestration, bronchial atresia, emphysema, bronchogenic cyst. They concern less than 1/10000 births and their physiopathological origin is still poorly understood. The main goal of this project is to pool the cases from different swiss centers on a prospective cohort study, first to increase knowledge of clinical and radiological evolution and their correlation with histological data, and second to analyse the pathological embryological mechanism underlying these malformations.
Worldwide, glaucoma is the most common cause of irreversible blindness. The major risk factor is raised pressure within the eye (intraocular pressure, IOP). IOP is typically measured using Goldman applanation tonometry (GAT). This involves instilling anaesthetic eye drops and using a probe to contact the cornea and obtain a pressure measurement. A major disadvantage of GAT is that only limited numbers of pressure measurements can be obtained, whereas IOP is known to vary throughout the day and in ¾ of people is highest during the night. The result is that clinicians have poor understanding of patient's 24 hour IOPs and the effect that this might have on their glaucoma. This is a serious limitation as the treatment of glaucoma depends on lowering IOP. Recently a new device has become available, designed specifically for home IOP monitoring. The iCare HOME tonometer is a CE marked commercial device (http://www.icaretonometer.com/products/icare-home-tonometer/) that can be used to gain insight into 24-hour IOP fluctuations. We wish to determine the feasibility of home IOP monitoring using this device. The iCare HOME tonometer depends on the patient performing self-tonometry. Testing one's own IOP may be technically difficult and it is likely that large numbers of patients will struggle with this.
The main goal of this study is to compare the use of Avanafil versus Sildenafil in spinal cord injury erectile dysfunction. The study has the characteristics of a non- inferiority, randomized, crossover, open clinical trial. The principal variable is the IIEF-EF (Erectile Function Domain questionnaire of the International Index of Erectile Function IIEF). This is an interventional study
Hyperinsulinemic hypoglycemia (HH) is a rare complication that occurs 1 to 5 years after gastric bypass surgery. The underlying mechanism of this complication is not yet completely understood. Changes in hormone levels, such as GLP1 after RYGB, nesidioblastosis or an increase in the number of beta cells may be one of the underlying causes. However, several study results are conflicting and it is hypothesized that the patient population with HH after RYGB is heterogeneous and several underlying causes may be present. In order to differentiate between hyperfunction with normal beta cell mass and a general or localized increase in beta cell mass we aim to compare quantitative 68Ga-exendin-4 PET imaging of the pancreas between patients with and without HH after RYGB. Thereby, investigators aim to increase the insight in the underlying mechanism of HH after RYGB. If different underlying causes can be diagnosed, treatment for HH can be optimized for patients.

Our goal is to demonstrate that 50mg of dasatinib is as effective as the full dose to induce molecular response as first line therapy in CML.
For newly-diagnosed patients with brain metastasis, whole brain radiation therapy (WBRT) probably remains a common palliative management even for those with oligometastatic brain disease. However, WBRT-related late sequelae, particularly a decline in neurocognitive functions (NCFs), are a major concern. More importantly, in patients with limited brain metastases and a fair/good performance status, sparing the radiosensitive and vulnerable structures which are responsible for essential NCFs during the WBRT course is one of the reasonable strategies to postpone and prevent the development of WBRT-induced neurocognitive impairments. Actually, radiation-related neurocognitive dysfunction is usually characterized as a decline involving learning and memory, in which the extremely radiosensitive hippocampus indeed plays a critical role. In addition to the neurocognitive preservation by virtue of sparing the radiosensitive structures like the hippocampus, durable intracranial tumor control critically depends on an escalated radiotherapeutic dose level which is adequate enough to eradicate gross metastatic brain lesions. Therefore, in order to achieve both hippocampal sparing and simultaneous integrated boost(s) to gross metastatic foci, a specialized WBRT technique, hippocampal avoidance during WBRT plus simultaneous integrated boost (SIB) will be adopted in this prospective study. Moreover, the dose-effect relationship would be analyzed in order to explore the correlation between the equivalent uniform dose (EUD) irradiating the hippocampus and the neurocognitive change/decline after the above WBRT course measured by objective neurocognitive test tools. Newly-diagnosed cancer patients harboring 1-3 gross metastatic lesions but still in fair/good performance statuses are potentially eligible. All recruited patients should receive baseline functional brain MRI examination and baseline neurobehavioral assessment. Treatment planning will be designed via the technique of volumetric-modulated arc therapy (VMAT) to achieve both hippocampal avoidance and simultaneous integrated boost(s) to gross metastatic lesions. Except for the above regions for which conformal avoidance or SIB is attempted, the prescribed dose to the remaining brain parenchyma will be consistently 3000 cGy in 12 fractions. Accordingly, a battery of neuropsychological measures, which includes 7 standardized neuropsychological tests (e.g., executive functions, verbal and non-verbal memory, working memory, and psychomotor speed), is used to evaluate neurobehavioral functions for our registered patients. The primary outcome measure is delayed recall, as determined by the change/decline in verbal memory or non-verbal memory, from the baseline assessment to 4 months after the start of the WBRT course. This prospective cohort study aims to examine thoroughly the impact of a specialized WBRT technique, integrating both simultaneous integrated boost(s) delivered to gross metastatic foci and conformal hippocampal avoidance, on the status of NCF change/decline in patients with oligometastatic brain disease. It is anticipated that intracranial local control will be more sustainable and durable resulting from the escalated focal dose of SIBs. Ultimately, we also expect the dose-effect relationship will be clearly demonstrated after investigating the correlation between the hippocampal dosimetry and the status of NCF change/decline after receiving HA-WBRT plus SIB.
