End-to-End Ultrasonic Hand Gesture Recognition.

As the number of electronic gadgets in our daily lives is increasing and most of them require some kind of human interaction, this demands innovative, convenient input methods. There are limitations to state-of-the-art (SotA) ultrasound-based hand gesture recognition (HGR) systems in terms of robustness and accuracy. This research presents a novel machine learning (ML)-based end-to-end solution for hand gesture recognition with low-cost micro-electromechanical (MEMS) system ultrasonic transducers.

Multiple sclerosis in the elderly: a retrospective cohort study.

Background: There is a lack of knowledge of disease course, prognosis, comorbidities and potential treatments of elderly MS patients.

Objective: To characterize the disease course including disability progression and relapses, to quantify the use of DMTs and to identify comorbidities and risk factors for progression in elderly multiple sclerosis (MS) patients.

Methods: This is a retrospective study of 1200 Austrian MS patients older than 55 years as of May 1st, 2017 representing roughly one-third of all the MS patients of this age in Austria.

Long-term outcome of natalizumab-associated progressive multifocal leukoencephalopathy in Austria: a nationwide retrospective study.

Background/objective: The use of natalizumab (NAT) in multiple sclerosis (MS) may be complicated by progressive multifocal leukoencephalopathy (PML), a rare and life-threatening opportunistic brain infection. We aimed to analyze the course of MS after PML recovery together with the long-term outcome of NAT-associated PML (NAT-PML) in Austria.

Methods: Retrospective study based on identification of cases in the nationwide Austrian MS treatment registry (AMSTR) and MS centers with review of patient records.

Thrombectomy in basilar artery occlusion.

Background And Purpose: The benefit of thrombectomy (TE) for acute ischemic stroke (AIS) in patients suffering basilar artery occlusion (BAO) is still unclear. Our aim was to analyze functional outcome after 3 months in BAO compared to anterior circulation large vessel occlusion (ACLVO) in a nationwide registry.

Methods: Patients enrolled into the Austrian Endostroke Registry from 2013 to 2018 were analyzed.

[Guideline S1: Long COVID: Diagnostics and treatment strategies].

This guideline comprises the state of science at the time of the editorial deadline. In view of the high turnover of knowledge the guideline is designed as a living guideline. The main objective was to provide a tool for the use in primary care, being considered well suited as a first point of entry and for the provision of care.

Complete and incomplete recurrent laryngeal nerve injury after thyroid and parathyroid surgery: Characterizing paralysis and paresis.

Background: Injury of the recurrent laryngeal nerve and consequent disorder of vocal fold movement is a typical complication in thyroid and parathyroid surgery. During postoperative laryngoscopy we observed not only a complete standstill (vocal fold paralysis), but also a hypomobility (paresis). In this prospective study, we investigated the difference in incidence and prognosis as well as risk-factors, intraoperative neuromonitoring, and symptoms between vocal fold paralysis and vocal fold paresis.

Can pulmonary sarcoidosis trigger a progressive multifocal leukoencephalopathy? Considerations from a case series and a review of literature.

Progressive multifocal leukoencephalopathy (PML) is a severe infectious brain disease with lethal outcome mainly seen in immunocompromised subjects. Herein, we describe a new form of PML with different outcome which was observed in patients suffering from systemic sarcoidosis. Thus, we raise the question whether preexisting sarcoidosis might predispose for or even trigger PML.

Is Functional Outcome Different in Posterior and Anterior Circulation Stroke?

Background and Purpose- Posterior circulation stroke (PCS) account for 20% of all ischemic strokes. There is limited evidence whether functional outcome of PCS is comparable to that of anterior circulation stroke (ACS). We aimed to analyze whether 3-month functional outcome is different in PCS and ACS.

Prehospital and intra-hospital time delays in posterior circulation stroke: results from the Austrian Stroke Unit Registry.

Therapeutic effect of recombinant tissue-plasminogen activator (rt-PA) is time dependent. There is limited evidence whether localization of stroke within the posterior circulation (PCS) is associated with a treatment delay. We aimed to analyze within a nationwide multicenter cohort whether duration of pre- and intra-hospital patient management differs between patients with PCS and anterior circulation strokes (ACS).

Predictive value of ABCD2 and ABCD3-I scores in TIA and minor stroke in the stroke unit setting.

Objective: It is not clear whether risk scores for early stroke recurrence after TIA that have been mainly established in outpatient and emergency department settings are valid on the background of highly specialized stroke unit care.

Methods: ABCD2 and ABCD3-I scores have been prospectively documented in a cohort of patients admitted to Austrian stroke units within 24 hours of symptom onset with TIA or minor stroke (NIH Stroke Scale score <4).

Results: A total of 5,237 TIA and minor stroke patients met inclusion criteria, with 3-month follow-up data available on 2,457.

Endovascular stroke therapy in Austria: a nationwide 1-year experience.

Background And Purpose: Based on a tight network of stroke units (SUs) and interventional centres, endovascular treatment of acute major intracranial vessel occlusion has been widely implemented in Austria. Documentation of all patients in the nationwide SU registry has thereby become mandatory.

Methods: Demographic, clinical and interventional characteristics of patients who underwent endovascular treatment for acute ischaemic stroke in 11 Austrian interventional centres between 1 October 2013 and 30 September 2014 were analysed.

Neuromyelitis optica in Austria in 2011: to bridge the gap between neuroepidemiological research and practice in a study population of 8.4 million people.

Background: In 2008 the Austrian Task Force for Neuromyelitis Optica (NMO) started a nation-wide network for information exchange and multi-centre collaboration. Their aim was to detect all patients with NMO or NMO spectrum disorders (NMO-SD) in Austria and to analyse their disease courses and response to treatment.

Methods: (1) As of March 2008, 1957 serum samples (of 1557 patients) have been tested with an established cell based immunofluorescence aquaporin-4 antibody (AQP4-ab) assay with a high sensitivity and specificity (both >95%).

Spinal cord lesions in patients with neuromyelitis optica: a retrospective long-term MRI follow-up study.

Neuromyelitis optica (NMO) is characterised by a particular pattern of the optic nerves and the spinal cord. Long-term MRI follow-up studies of spinal NMO lesions are rare, or limited by short observation periods. In nine patients with definite NMO or recurrent longitudinally extensive transverse myelitis (LETM) with NMO-IgG serum antibodies, repeated MRI examinations of the spine were carried out over a period of up to 11 years and evaluated regarding the changes over time in this retrospective study.

[Subcutaneous interferon-beta-1a in the treatment of multiple sclerosis].

During the last 10 years recombinant interferon-beta-1a administered subcutaneously has been the subject of several clinical trials in relapsing remitting multiple sclerosis (RRMS), in secondary progressive MS (SPMS), as well as in clinically isolated syndromes. All of them met the criteria of evidence level class I. Consistent evidence for moderate immunomodulatory effects on clinical parameters of disease activity was gained, and even higher efficacy of IFN-beta-1a sc.
