Effectiveness and safety of electrical cardioversion for acute-onset atrial fibrillation in the emergency department: a real-world 10-year single cen…
2019
OBJECTIVE Despite limited evidence, electrical cardioversion of acute-onset atrial fibrillation (AAF) is widely performed in the emergency department (ED). The aim of this study was to describe the effectiveness and safety of electrical cardioversion of AAF performed by emergency physicians in the ED. METHODS All episodes of AAF electrically cardioverted in the ED were retrieved from the database for a 10-year period. Most patients not already receiving anticoagulants were given enoxaparin before the procedure (259/419). Procedural complications were recorded, and the patients were followed-up for 30 days for cardiovascular and hemorrhagic complications. RESULTS Four hundred nineteen eligib…
Soziale Medien als fünfte Gewalt: Strategische Organisation deutscher und finnischer Gegenredekampagnen auf Facebook
2023
Social media, as the fifth estate, increasingly influence public discourses and play a major role in shaping public opinion. Undoubtedly, they have the potential to promote participation and democracy. On the other side, they also constitute a risk for democratic societies, as the spread of hate speech and fake news has shown. As a response, forms of counterspeech organised by civil society have emerged in social media to counter the normalisation of hate speech and democracy-threatening discourses. In order to influence discourse in social media in terms of the fifth estate, counterspeech campaigns must be visible also quantitatively. In this ethnographic contrastive study, I analysed…
[Is ICD-programming for double intraoperative defibrillation threshold energy safe and effective during long-time follow-up? Results of a prospective…
1999
The aim of this prospective and randomized study was to evaluate the safety and efficacy of a reduced shock strength in transvenous implantable defibrillator therapy. So far clinical data concerning the safety margin of the shock energy in ICD therapy do not exist. The shock energy tested during long-term follow-up in this study was twice the intraoperatively measured defibrillation threshold (DFT). A total number of 176 consecutive patients representing a typical cohort of ICD patients were evaluated. All patients received a non-thoracotomy lead system (CPI, Endotak 0070, 0090) and a biphasic cardioverter-defibrillator with the ability to store episodes (Cardiac Pacemakers Inc., Ventac TM …
Towards an Economy of Encounters? : A critical study of affectual assemblages in coworking
2017
Abstract Coworking spaces have been established in great numbers around the globe over the past 10 years. Previous studies on coworking spaces argue that these spaces are designed to enable serendipitous encounters. Here we introduce the concept of an economy of encounters, arguing that both intended and unintended encounters have become a form of production in the knowledge-based new economy. This paper draws upon the critical analysis of three case studies of different coworking settings − two open coworking spaces and a corporate coworking office. Following Deleuze and Guattari, we see coworking spaces as affectual assemblages that create affects that push knowledge workers in flow and m…

The role of the renin-angiotensin system in atrial fibrillation and the therapeutic effects of ACE-Is and ARBS
2008
Atrial fibrillation (AF) is the most common rhythm disturbance in medical practice and represents a very expensive health problem. AF can be managed with the prevention of thromboembolism and either a rate control of rhythm strategy. As both strategies have important limitations, probably a preventative strategy in patients at risk of developing arrhythmia can be a more attractive option. The renin-angiotensin system (RAS) seems to be involved in the genesis of arrhythmia by the following two mechanisms: 1. the induction of atrial fibrosis and structural remodelling by mitogen-activated protein kinase (MAPK) expression and reduction of collagenase activity; 2. the induction of electrical re…
Pharmacological Therapy in Children with Atrial Fibrillation and Atrial Flutter
2008
Heart rhythm disorders in children are not different, on electrocardiographic trace, from heart rhythm disorders in adults with the exception of incidence which is different according to the age. Paticularly, atrial flutter (FlA) and fibrillation (FA) are very uncommon arrhythmias in the general pediatric population. Generally atrial fibrillation and atrial flutter, in our experience, is a temporary heart rhythm disturbance connected to specifical and resovable reasons with the exception of Fontains surgical correction of congenital heart diseases or cardiopathies with dilatation of both atria. Presenting symptoms, symptom history (e.g., frequency, duration, and severity), risk assessment, …
Focus on right ventricular outflow tract septal pacing
2013
SummaryExperimental and clinical studies have shown that right ventricular apical pacing may result in long-term deleterious effects on account of its negative impact on left ventricular remodeling through desynchronization. This risk appears more pronounced in patients with even moderate left ventricular dysfunction and generally occurs after at least 1 year of pacing. As right ventricular apical pacing may be associated with the development of organic mitral insufficiency, other sites that allow for more physiological stimulation, such as right ventricular outflow tract septal pacing, have been developed, with good feasibility and reproducibility. However, the prospective randomized studi…
Prospective appraisal of the prevalence of primary aldosteronism in hypertensive patients presenting with atrial flutter or fibrillation (PAPPHY Stud…
2013
Primary aldosteronism (PA) is the most common endocrine form of hypertension and may carry an increased risk of atrial flutter or fibrillation (AFF). The primary goal of this multicentre cohort study is thus to prospectively establish the prevalence of PA in consecutive hypertensive patients referred for lone (non-valvular), paroxysmal or permanent AFF. Secondary objectives are to determine: (1) the predictors of AFF in patients with PA; (2) the rate of AFF recurrence at follow-up after specific treatment in the patients with PA; (3) the effect of AFF that can increase atrial natriuretic peptide via the atrial stretch and thereby blunt aldosterone secretion, on the aldosterone-to-renin rati…
Doing Respectable Heteromasculinities in Boys and Young Men’s Interview Talk on Sexual Encounters
2022
Recent studies on boys and young men’s heterosexual practices point in contradictory directions. On the one hand, boys and young men seem to be placing less value on “hard”, overtly aggressive masculinity and compulsive heterosexuality, in keeping with their adoption of more egalitarian attitudes in their sexual relationships. On the other hand, the hegemonic masculine notions that associate “real” men with sexual prowess persist as well. In this article, we argue that this contradiction indicates careful (re)calibration in doing respectable heteromasculinities. We draw on a small-scale qualitative study located in Helsinki, Finland, in illuminating how cis-gendered boys and young men with…
