[Transarterial periarticular embolization (TAPE) for treatment of achillodynia: initial results].

Background: In recent years, transarterial periarticular embolization (TAPE) has received increasing attention in the treatment of chronic joint pain, which can be caused by degenerative changes such as osteoarthritis but also by inflammatory changes in the capsule-ligament apparatus.

Objectives: The aim of this study is to describe the method as well as preliminary results of TAPE in the treatment of therapy-resistant achillodynia.

Material And Methods: TAPE was used in the treatment of seven patients (female: 1, male: 6) with chronic achillodynia.

Oral Anticoagulation and Mortality in Cases with Intracranial Bleeding: Analysis of Nationwide Prescription and Hospitalization Data.

Objectives:  To demonstrate the safety of direct oral anticoagulants in relation to intracranial bleeding (ICB), we compared the number of patients taking anticoagulants in all cases of hospitalization and cases of hospitalization for ICB over time in Germany. We analyzed the intrahospital mortality of ICB cases in relation to long-term use of anticoagulants (LUAs).We performed a retrospective registry analysis of nationwide German hospitalizations including all hospital admissions and admission for ICB in patients aged ≥60 years in the period from 2006 to 2020 and separated for LUAs.

Endovascular treatment of renal artery stenosis in Germany: a retrospective analysis of the DEGIR registry 2018-2021.

Purpose: To provide an overview of endovascular treatment of renal artery stenosis (RAS) using the data of the Deutsche Gesellschaft für interventionelle Radiologie (DeGIR) quality management system.

Materials And Methods: A retrospective analysis was performed. Pre-, peri- and postprocedural data, technical success rates, complication rates, and clinical success rates at dismissal were examined.

Machine learning based prediction of length of stay in acute ischaemic stroke of the anterior circulation in patients treated with thrombectomy.

Background: Length of stay is an important factor for managing the limited resources of a hospital. The early, accurate prediction of hospital length of stay leads to the optimized disposition of resources particularly in complex stroke treatment.

Objective: In the present study we evaluated different machine learning techniques in their ability to predict the length of stay of patients with stroke of the anterior circulation who were treated with thrombectomy.

Thrombectomy in ischemic stroke patients with alberta stroke program early computed tomography score 4-5 and 0-3: Factors associated with favorable outcome.

Objectives: Recently published results of the ANGEL-ASPECT and SELECT2 trials suggest that stroke patients presenting with low Alberta Stroke Program Early Computed Tomography Score (ASPECTS) benefit from mechanical thrombectomy. Purpose of this retrospective study was to identify factors that are associated with a favorable outcome in patients with low ASPECTS of 4-5 and 0-3 undergoing mechanical thrombectomy.

Material And Methods: All patients reported in the quality registry of the German Society for Neuroradiology that were treated between 2018 and 2020 were analyzed.

Outcome prediction prior to thrombectomy of the posterior circulation with machine learning.

Purpose: Various studies have identified prognostic factors for a favorable outcome of endovascular treatment in posterior circulation. We evaluated various machine learning algorithms in their ability to classify between patients with favorable (defined as 0-2 points on the modified Rankin scale [mRS]), unfavorable (mRS 3-6), poor (mRS 5-6), and nonpoor (mRS 0-4) outcomes at dismissal.

Methods: We retrospectively analyzed data from 415 patients that were treated between 2018 and 2021 from the multicentric DGNR registry.

Parameters Associated with the Required Drug Dose of Intravenous Immunoglobulin in Stable Chronic Inflammatory Demyelinating Polyradiculoneuropathy.

Background: Intravenous immunoglobulin (IVIg) is efficient and one of very few treatment options for patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). However, finding the optimal dose of IVIg for individual CIDP patients remains challenging. The dose of IVIg needs to be adjusted individually.

Feasibility of Network-Based, Online Endovascular Simulator Training in Real Time: Results from a Pilot Study.

Purpose: To test the feasibility of an online, simulator-based comprehensive interventional radiology (IR) training curriculum in times of COVID-19-induced travel restrictions.

Materials And Methods: A network of six VIST simulators (Mentice, Gothenburg, Sweden) was installed in six geographically different radiology departments. Two courses with six sessions each took place.

Thrombectomy of Mild Stroke : An Analysis of the Nationwide Registry of the German Society for Neuroradiology.

Purpose: Whether patients presenting with mild stroke (NIHSS at admission < 6) should be treated with mechanical thrombectomy (MT) is the subject of an ongoing debate. This retrospective study based on large-scale clinical data aims to identify factors associated with favorable outcome (FO) in patients with mild stroke.

Methods: A total of 761 patients with mild stroke enrolled between 1 January 2020 and 31 December 2020 in the Quality Registry of the German Society for Neuroradiology were analyzed.

Machine learning based outcome prediction of large vessel occlusion of the anterior circulation prior to thrombectomy in patients with wake-up stroke.

Purpose: Outcome prediction of large vessel occlusion of the anterior circulation in patients with wake-up stroke is important to identify patients that will benefit from thrombectomy. Currently, mismatch concepts that require MRI or CT-Perfusion (CTP) are recommended to identify these patients. We evaluated machine learning algorithms in their ability to discriminate between patients with favorable (defined as a modified Rankin Scale (mRS) score of 0-2) and unfavorable (mRS 3-6) outcome and between patients with poor (mRS5-6) and non-poor (mRS 0-4) outcome.

Pulsed field ablation for pulmonary vein isolation: real-world experience and characterization of the antral lesion size compared with cryoballoon ablation.

Background: Pulsed field ablation (PFA) is a new, non-thermal technology in the treatment of atrial fibrillation (AF). Early investigations have shown a promising safety profile with durable pulmonary vein isolation (PVI) and large antral lesions. However, clinical data remains scarce.

Telemonitoring Potential of Wearable Cardioverter-Defibrillators during the Follow-Up of Patients with Heart Failure.

Background: Wearable cardioverter-defibrillators (WCDs) are a well-established tool to bridge the recovery time of left ventricular ejection fraction (LVEF) until the implantation of an implantable cardioverter defibrillator (ICD), as recommended by the current guidelines. Besides their function to detect and treat malignant arrhythmias, WCDs may be used as a telemonitoring system. In this study, we sought to illustrate and discuss the telemonitoring potential of WCDs and to analyze physical activity in specific patient cohorts.

Value of machine learning to predict functional outcome of endovascular treatment for acute ischaemic stroke of the posterior circulation.

Purpose: Clinical outcomes vary considerably among individuals with vessel occlusion of the posterior circulation. In the present study we evaluated machine learning algorithms in their ability to discriminate between favourable and unfavourable outcomes in patients with endovascular treatment of acute ischaemic stroke of the posterior circulation.

Methods: This retrospective study evaluated three algorithms (generalised linear model, K-nearest neighbour and random forest) to predict functional outcomes at dismissal of 30 patients with acute occlusion of the basilar artery who were treated with thrombectomy.

Material And Methods:  TAPE was performed in three patients with chronic pain in different joints. In the first case the patient suffered from osteoarthritis of the shoulder, in the second case from epicondylitis humeri ulnaris ("golfer-elbow") and in the third case from patellar tendinitis ("jumpers-knee").

Volume reduction of the entorhinal cortex in subjective memory impairment.

To examine the biological basis of subjective memory impairment (SMI), defined as the feeling of memory worsening with normal memory performance, we measured the volume of the entorhinal cortex (EC) and the hippocampus in SMI subjects, patients with mild cognitive impairment (MCI), patients with Alzheimer's disease (AD) and healthy controls (CO). Compared with controls, the EC was smaller in the SMI group (left: p=0.060; right: p=0.
