Proof of Concept of Telemedicine-Assisted Abdominal Ultrasound Examinations to Improve the Quality of Patient Care in Rural Areas.

(1) Unclear sonographic findings without adequate specialist expertise in abdominal ultrasound (AU) may harm patients in rural areas, due to overlooked diagnoses, unnecessary additional imaging (e.g., CT scan), and/or patient transport to referral expert centers.

Gastrointestinal endoscopy in patients receiving novel direct oral anticoagulants: results from the prospective Dresden NOAC registry.

Background: Patients receiving direct-acting, non-vitamin K oral anticoagulants (NOAC) frequently undergo gastrointestinal endoscopies (GIE) but little is known on the management and outcome of these interventions.

Methods: With use of data from an ongoing, prospective, noninterventional registry of NOAC patients, the management and outcome of GIE were evaluated with use of standard event definitions. Patients undergoing GIE were categorized into two subgroups: (1) scheduled GIE (scheduled appointment, no acute bleeding) and (2) unscheduled GIE (unscheduled including management of acute gastrointestinal bleeding).

Management and outcome of gastrointestinal bleeding in patients taking oral anticoagulants or antiplatelet drugs.

Background: Non-vitamin K dependent oral anticoagulants (NOACs) significantly decrease overall major bleeding rates compared with vitamin K antagonists (VKAs) but there is conflicting evidence regarding the relative risk of gastrointestinal bleeding. Since data regarding the types, the management, and the outcome of NOAC-associated gastrointestinal bleeding are scarce, we aimed to fill this gap by comparing cases of gastrointestinal bleeding associated with NOAC, VKA, or antiplatelet therapy.

Methods: All major gastrointestinal bleeding events documented in the prospective Dresden NOAC registry were identified, and bleeding location, lesion type, endoscopic treatment, use of blood and coagulation factor transfusion, length of stay, and in-hospital mortality were compared with historical data from a large cohort of consecutive gastrointestinal bleeding patients.

Flexible percutaneous endoscopic retroperitoneal necrosectomy as rescue therapy for pancreatic necroses beyond the reach of endoscopic ultrasonography: A case series.

Minimally invasive or endoscopic transluminal drainage and necrosectomy are the standard of care for infected pancreatic fluid collections and necroses after pancreatitis. In an endoscopic treatment algorithm, necroses beyond the reach of safe endoscopic access are typically treated by percutaneous drainage. We aimed to evaluate percutaneous minimally invasive necrosectomy using a purely endoscopic technique in patients with extensive necrosis.

[New oral anticoagulants and endoscopy--what do you have to consider?].

Anti-coagulated patients often undergo endoscopic procedures and non-vitamin-K-antagonist oral anticoagulants (NOAC) are increasingly prescribed. Consequently, a comprehensive knowledge about the adequate peri-interventional handling of these substances is required. A standardized approach needs to be planned for elective and emergency situations.

Selection, management, and outcome of vitamin K antagonist-treated patients with atrial fibrillation not switched to novel oral anticoagulants. Results from the Dresden NOAC registry.

Atrial fibrillation (AF) patients treated with well-controlled vitamin K antagonists (VKAs) may benefit less from non-vitamin K antagonist oral anticoagulants (NOACs) because they are supposed to be at low risk of thromboembolic and bleeding complications. However, little is known about the selection, management, and outcome of such "stable" VKA patients in current practice. We assessed characteristics, VKA persistence and 12 months' outcome of AF patients selected for VKA continuation.

Effectiveness and safety of dabigatran therapy in daily-care patients with atrial fibrillation. Results from the Dresden NOAC Registry.

The effectiveness and safety of dabigatran for stroke prevention in atrial fibrillation (SPAF) demonstrated in RE-LY needs to be confirmed in daily care. To evaluate treatment persistence, effectiveness and safety of dabigatran therapy in SPAF patients in daily care, we used data from an ongoing, prospective, non-interventional registry of more than 2,500 patients on novel oral anticoagulants in daily care. Between October 1, 2011 and February 28, 2013, a total of 341 SPAF patients receiving dabigatran were enrolled.

Rates, management, and outcome of rivaroxaban bleeding in daily care: results from the Dresden NOAC registry.

Worldwide, rivaroxaban is increasingly used for stroke prevention in atrial fibrillation and treatment of venous thromboembolism, but little is known about rivaroxaban-related bleeding complications in daily care. Using data from a prospective, noninterventional oral anticoagulation registry of daily care patients (Dresden NOAC registry), we analyzed rates, management, and outcome of rivaroxaban-related bleeding. Between October 1, 2011, and December 31, 2013, 1776 rivaroxaban patients were enrolled.

Association of Oesophageal Varices and Splanchnic Vein Thromboses in Patients with JAK2-Positive Myeloproliferative Neoplasms: Presentation of Two Cases and Data from a Retrospective Analysis.

Background: Oesophageal varices and gastrointestinal bleeding are common complications of liver cirrhosis. More rarely, oesophageal varices occur in patients with non-cirrhotic portal hypertension that results from thromboses of portal or splanchnic veins.

Case Report: We describe 2 young men who initially presented with varices as a result of portal vein thromboses.

Decreased caveolin-1 in atheroma: loss of antiproliferative control of vascular smooth muscle cells in atherosclerosis.

Objective: Proliferation of vascular smooth muscle cells (VSMC) is involved in the pathogenesis of primary atherosclerosis and restenosis after angioplasty. On the background of the antiproliferative activities of caveolin-1, the present study focused on the expression of caveolin-1 in proliferating VSMC of human atheroma.

Methods: VSMC were isolated from wild-type (Wt) and caveolin-1 knockout mice (Cav-/-).
