This Endoscopic Ultrasound guided Biliary Drainage (EUS-BD) vs. Endoscopic Retrograde Cholangiopancreatography (ERCP-TP) trial (BILPAL) is a randomized controlled multicenter trial that will provide evidence whether or not traditional ERCP biliary drainage is to be performed in patients with obstruction in bile duct due to unresectable pancreatic head or periampullary tumor.
NCT00238446
This purpose of this extension study of patients being treated with EC-MPS is to assess the long term safety of this medication.
NCT01817907
In Obstructive sleep apnea (OSA), the upper airway closes over and over again during sleep. This leads to disrupted sleep (waking up during the night), daytime sleepiness, and an increased risk for developing high blood pressure. Currently, the best treatment for obstructive sleep apnea is sleeping with a mask that continuously blows air into the nose (i.e. Continuous positive airway pressure \[CPAP\] treatment). While CPAP treatment stops the upper airway from closing in most people, many people have difficulty sleeping with the mask in place and therefore do not use the CPAP treatment. This research study is being conducted to learn whether using a sedative will improve OSA severity by altering some of the traits that are responsible for the disorder.
NCT01060085
The primary objective of this study is to compare the diagnostic accuracy of Digital Breast Tomosynthesis (DBT) versus that of Contrast Enhanced Magnetic Resonance Imaging (CEMRI) in determining the size of breast cancer preoperatively. Secondary objectives include: 1. Comparing the operating characteristics of each combined imaging protocol with respect to the reference standard, i.e. histopathologic assessment, of additional non-index lesions. 2. Comparison of re-excision rates based on estimated disease extent from adjunctive CEMRI vs. adjunctive DBT. 3. Evaluation of patient satisfaction with regard to the adjunctive modality (DBT vs. CEMRI).
NCT00706056
The objective of this study is to determine whether systemic blood pressure in the body is related to the development and progression of normal tension glaucoma in the eye. The study aims to clarify whether subjects with episodes of hypotension (low blood pressure) at night are at increased risk for sight loss and the development of normal tension glaucoma.
NCT02313259
The purpose of the study was (1) to determine thresholds for discriminating speed in peripheral fields of patients with dry AMD and (2) to examine the driving skills of licensed drivers with early dry AMD using a driving simulator and to investigate how their healthy counterparts perform on the same driving tasks. We hypothesized that speed discrimination may be better in patients with dry AMD than in healthy control subjects.
NCT03054116
In a prospective, observational study the investigators compared resistance values measured using the airway perturbation device (APD) to impulse oscillometry and spirometry. The investigators also created reference equations for normal APD resistance ranges using the data from clinically normal volunteers.
NCT03061617
It is controversial as to which ventilation mode is better in one-lung ventilation(OLV), volume controlled ventilation(VCV) or pressure controlled ventilation(PCV). This study was designed to figure out if there was any difference between these two modes on oxygenation and postoperative complications under the condition of protective ventilation(PV).
NCT02215317
Elucidating the effects of obstructive sleep apnea (OSA) on cardiovascular outcomes is crucial in risk assessments and therapeutic recommendations for affected individuals. The Sleep and Stent Study is a multi-center observational study investigating the relationships between OSA and cardiovascular outcomes in patients treated with percutaneous coronary intervention (PCI).
NCT01755013
Successful palliation of biliary obstruction is the main goal for reducing morbidity and mortality in patients with biliary disease and biliary obstruction related to cholangiocarcinoma. Surgical intervention for the sale is unfortunately complicated by a 30-day postoperative mortality rate of between 7 and 24%. Moreover, because of recovery time the quality of life following surgery is only improved in a minority. At present endoscopic insertion of a plastic or metal stent is the method of choice to relieve obstructive jaundice without the high morbidity and mortality associated with surgery. But this relief is unfortunately temporary since stents tend to become obstructed and the fact that effective biliary drainage in the proximal lesion is challenging. Photodynamic Therapy (PDT) is a new therapeutic approach that specifically targets neoplastic cells. This therapy involves the intravenous administration of a photosensitizing agent followed by activation of the agent by illumination with non-thermal light of a specific wavelength, resulting in cell death from direct cytotoxicity and ischemic necrosis. A randomized controlled trial study by Ortner et all confirmed the significant advantage of PDT with regard to relief of jaundice, quality of life, and survival. In photodynamic therapy (PDT) the uniform distribution of externally applied light is desirable but often difficult to achieve. An optical fiber tip producing cylindrical or lateral light emission can facilitate the application of laser energy by direct implantation of the tip into solid tumors. However, currently used FDA approved glass diffusers used in standard of care PDT might break in the bile ducts causing injury since they are not meant to be used within bile ducts through an endoscope or choledochoscope. Hence, there is a need to evaluate and introduce more efficient and safe non-glass cylindrical optic fiber diffuser for photo dynamic therapy in the bile ducts. Recent studies have shown that the Pioneer plastic optic diffuser is safe and effective in photodynamic therapy, it can be also used via a choledochoscope. We aim to add to the clinical evidence by conducting an open label observational study trial using this fiber optic diffuser during photo dynamic therapy in the bile ducts.
NCT00358150
Gaucher disease is a genetic disease that results in a deficiency of an enzyme acid beta-glucosidase, also known as glucocerebrosidase. This enzyme is needed to digest a substrate (lipid) called glucosylceramide and, to a lesser degree, glucosylsphingosine. In participants with Gaucher disease, the liver, spleen, bone marrow and brain show increases in lipid concentration, specifically in cells derived from the monocyte/macrophage system. Eliglustat tartrate (Genz-112638) is an oral drug that may regulate the Gaucher disease process by decreasing the synthesis of glucosylceramide. The primary objective of this study is to evaluate the efficacy, safety and pharmacokinetics (PK) of eliglustat tartrate, administered as an oral dose of either 50 milligram (mg) twice daily (BID) or 100 mg BID, to men and women with Gaucher disease Type 1 for 52 weeks.
NCT01462942
The objective is to provide data supporting the use of LAS40464 as an efficacious and safe maintenance bronchodilator treatment of patients with Chronic Obstructive Pulmonary Disease (COPD).
NCT02877641
This phase IIb randomized trial studies how well cholecalciferol (vitamin D3) supplementation works in strengthening inspiratory muscles in cholecalciferol-deficient patients with chronic obstructive pulmonary disease (COPD). Cholecalciferol supplementation may help reduce the risk of developing lung cancer and strengthen the diaphragm in cholecalciferol-deficient patients with COPD.
NCT03050593

NCT02296372
Critically ill patients are on high risk for increased serum glucose levels, leading to more comorbidity and higher mortality risk. In patients with severe sepsis and septic shock hyperglycemia is a typical finding. However the need of insulin therapy is associated with an increased risk of hypoglycemia. Newly developed technologies for continuous glucose monitoring in critically ill patients may improve glycemic control and reduce glucose variability. The investigators will perform continuous glucose monitoring in critically ill patients on ICU. Measurements will be done for a period of 72h per patient. The investigators aim is to evaluate accuracy feasibility and acceptance of these methods. To analyze accuracy sensor glucose levels will be validated due to arterial blood gas measurements with the blood gas analyzer. The investigators will investigate the influence of several factors like oedema, perspiration, BMI, body temperature, pH-value application of vasoconstrictors on accuracy and feasibility of the particular system. Furthermore Nursing staff will be given a questionnaire to identify acceptance.
NCT03030573
The investigators developed a new surgical technique in order to reconstruct the bile duct with the round ligament
NCT01074944
The primary objective of this study was to evaluate the efficacy and safety of once daily (QD) versus twice daily (BID) dosing of eliglustat tartrate (Genz-112638) in participants with Gaucher disease type 1 who had demonstrated clinical stability on BID dosing of eliglustat tartrate (Genz-112638). The secondary objective was to evaluate the pharmacokinetics (PK) of Genz-99067 when eliglustat tartrate (Genz-112638) was administered QD and BID in participants with Gaucher disease type 1 who had demonstrated clinical stability on BID dosing of eliglustat tartrate (Genz-112638).
