Hungarian media laws in Europe: An assessment of the consistency of Hungary's media laws with European practices and norms

A new CMCS study led by researcher Amy Brouillette analyses the consistency of the Hungarian media regulations with European practices and norms. It addresses a key international policy debate regarding the conformity of Hungary's new media legislation to European and EU media-regulation standards. The study also contributes to the ongoing policy making process regarding Hungary's media laws-particularly in light of the recent rulings by Hungary's Constitutional Court which requires several provisions to be amended by 31 May 2012-as well as contributing to the debate around other areas of concern that have been raised by the European Commission, European lawmakers, and domestic and international stakeholders

RF MEMS Switches for Mobile Communication

Switched capacitors based on radio frequency microelectromechanical systems (RF MEMS) can enable a breakthrough in radio technology. Their switching principle is based on the mechanical movement of the plates of a parallel plate capacitor using the electrostatic force. The resulting difference in capacitance is used to switch an RF signal. This article discusses the device physics and application of these Microsystems

Internal phase inversion narrow bandwidth MEMS filter

This paper reports a novel capacitively coupled twin beam resonator internal phase inversion filter fabricated in a SOI MEMS process. A narrow bandwidth of 0.0157% is demonstrated with a low control-voltage of -0.87 V. The bandwidth can be substantially reduced by utilizing an electrical coupling spring as opposed to a mechanical coupling-spring. The bandwidth is tunable with control achieved using a differential DC bias. A summary and comparison with other members of the phase inversion filter family is also included

The effects of serious gaming on risk perceptions of climate tipping points

A growing body of research indicates that effective science-policy interactions demand novel approaches, especially in policy domains with long time horizons like climate change. Serious games offer promising opportunities in this regard, but empirical research on game effects and games’ effectiveness in supporting science-policy engagement remains limited. We investigated the effects of a role-playing simulation game on risk perceptions associated with climate tipping points among a knowledgeable and engaged audience of non-governmental observers of the international climate negotiations and scientists. We analysed its effects on concern, perceived seriousness, perceived likelihood and psychological distance of tipping points, using pre- and post-game surveys, debriefing questions and game observations. Our findings suggest that the game reduced the psychological distance of tipping points, rendering them more ‘real’, proximate and tangible for participants. More generally, our findings indicate that role-playing simulation games, depending on their design and future orientation, can provide effective science-policy engagement tools that allow players to engage in future thinking and corresponding meaning making.publishedVersio

Health-Related Quality of Life in Relation to Obesity Grade, Type 2 Diabetes, Metabolic Syndrome and Inflammation

Health-related quality of life (HR-QoL) may be compromised in obese individuals, depending on the presence of other complications. The aim of this study is to assess the effect of obesity-related conditions on HR-QoL. These conditions are i) grade of obesity with and without type 2 diabetes (T2D), ii) metabolic syndrome (MetS), and iii) level of inflammation.From the Dutch LifeLines Cohort Study we included 13,686 obese individuals, aged 18-80 years. HR-QoL was measured with the RAND 36-Item Health Survey which encompasses eight health domains. We calculated the percentage of obese individuals with poor HR-QoL, i.e. those scoring below the domain and sex specific cut-off value derived from the normal weight population. Logistic regression analysis was used to calculate the probability of having poor domain scores according to the conditions under study.Higher grades of obesity and the additional presence of T2D were associated with lower HR-QoL, particularly in the domains physical functioning (men: odds ratios (ORs) 1.48-11.34, P<0.005, and women: ORs 1.66-5.05, P<0.001) and general health (men: ORs 1.44-3.07, P<0.005, and women: ORs 1.36-3.73, P<0.001). A higher percentage of obese individuals with MetS had a poor HR-QoL than those without MetS. Furthermore, we observed a linear trend between inflammation and the percentage of obese individuals with poor scores on the HR-QoL domains. Individuals with MetS were more likely to have poor scores in the domains general health, vitality, social functioning and role limitations due to emotional problems. Obese women with increased inflammation levels were more likely to have poor scores on all domains except role limitations due to emotional problems and mental health.The impact of obesity on an individual's quality of life is enhanced by grade of obesity, T2D, MetS and inflammation and are mainly related to reduced physical health. The mental well-being is less often impaired

Impact of alcohol septal ablation on left anterior descending coronary artery blood flow in hypertrophic obstructive cardiomyopathy

Objectives: The aim of this study was to evaluate the effects of alcohol septal ablation (ASA) on coronary blood flow in symptomatic hypertrophic obstructive cardiomyopathy (HOCM) using cardiac MR (CMR) coronary flow measurements. Background: CMR flow mapping enables quantification of coronary blood flow in a noninvasive way. Both left ventricular outflow tract (LVOT) gradient reduction and myocardial scarring after ASA are expected to influence left anterior descending (LAD) coronary blood flow. Methods: Cine, contrast-enhanced (CE) imaging and breath-hold CMR phase contrast velocity mapping were performed at baseline and 1 and 6 months after ASA in seven patients. Changes of coronary blood flow were related to left ventricular (LV) mass reduction, enzyme release, volume of ethanol administered, LVOT gradient reduction, and LV rate pressure product (LVRPP). Results: A significant mass reduction was observed bothin the target septal myocardium and in the total myocardium (both P < 0.01). Mean myoca

Case Report:Immune dysregulation associated with long-lasting regression of a (pre)leukemic clone

Regression of leukemia in the absence of disease-modifying therapy remains poorly understood, although immunological mechanisms are thought to play a role. Here, we present a unique case of a 17-year-old boy with immune dysregulation and long-lasting regression of a (pre)leukemic clone in the absence of disease-modifying therapy. Using molecular and immunological analyses, we identified bone marrow features associated with disease control and loss thereof. In addition, our case reveals that detection of certain fusion genes with hardly any blasts in the bone marrow may be indicative of an accompanying oncogenic fusion gene, with implications for disease surveillance- and management in future patients.</p

Complement C5 contributes to brain injury after subarachnoid hemorrhage

Previous studies showed that complement activation is associated with poor functional outcome after aneurysmal subarachnoid hemorrhage (SAH). We investigated whether complement activation is underlying brain injury after aneurysmal SAH (n = 7) and if it is an appropriate treatment target. We investigated complement expression in brain tissue of aneurysmal SAH patients (n = 930) and studied the role of common genetic variants in C3 and C5 genes in outcome. We analyzed plasma levels (n = 229) to identify the functionality of a single nucleotide polymorphism (SNP) associated with outcome. The time course of C5a levels was measured in plasma (n = 31) and CSF (n = 10). In an SAH mouse model, we studied the extent of microglia activation and cell death in wild-type mice, mice lacking the C5a receptor, and in mice treated with C5-specific antibodies (n = 15 per group). Brain sections from aneurysmal SAH patients showed increased presence of complement components C1q and C3/C3b/iC3B compared to controls. The complement component 5 (C5) SNP correlated with C5a plasma levels and poor disease outcome. Serial measurements in CSF revealed that C5a was > 1400-fold increased 1 day after aneurysmal SAH and then gradually decreased. C5a in plasma was 2-fold increased at days 3–10 after aneurysmal SAH. In the SAH mouse model, we observed a ≈ 40% reduction in both microglia activation and cell death in mice lacking the C5a receptor, and in mice treated with C5-specific antibodies. These data show that C5 contributes to brain injury after experimental SAH, and support further study of C5-specific antibodies as novel treatment option to reduce brain injury and improve prognosis after aneurysmal SAH

Disruptions of Anaerobic Gut Bacteria Are Associated with Stroke and Post-stroke Infection : a Prospective Case-Control Study

In recent years, preclinical studies have illustrated the potential role of intestinal bacterial composition in the risk of stroke and post-stroke infections. The results of these studies suggest that bacteria capable of producing volatile metabolites, including trimethylamine-N-oxide (TMAO) and butyrate, play opposing, yet important roles in the cascade of events leading to stroke. However, no large-scale studies have been undertaken to determine the abundance of these bacterial communities in stroke patients and to assess the impact of disrupted compositions of the intestinal microbiota on patient outcomes. In this prospective case-control study, rectal swabs from 349 ischemic and hemorrhagic stroke patients (median age, 71 years; IQR: 67-75) were collected within 24 h of hospital admission. Samples were subjected to 16S rRNA amplicon sequencing and subsequently compared with samples obtained from 51 outpatient age- and sex-matched controls (median age, 72 years; IQR, 62-80) with similar cardiovascular risk profiles but without active signs of stroke. Plasma protein biomarkers were analyzed using a combination of nuclear magnetic resonance (NMR) spectroscopy and liquid chromatography-mass spectrometry (LC-MS). Alpha and beta diversity analyses revealed higher disruption of intestinal communities during ischemic and hemorrhagic stroke compared with non-stroke matched control subjects. Additionally, we observed an enrichment of bacteria implicated in TMAO production and a loss of butyrate-producing bacteria. Stroke patients displayed two-fold lower plasma levels of TMAO than controls (median 1.97 vs 4.03 mu M, Wilcoxonp <0.0001). Finally, lower abundance of butyrate-producing bacteria within 24 h of hospital admission was an independent predictor of enhanced risk of post-stroke infection (odds ratio 0.77,p = 0.005), but not of mortality or functional patient outcome. In conclusion, aberrations in trimethylamine- and butyrate-producing gut bacteria are associated with stroke and stroke-associated infections.Peer reviewe

Patient-reported daily functioning after SARS-CoV-2 vaccinations in autoimmune neuromuscular diseases

Background and purpose: There are concerns for safety regarding SARS-CoV-2 vaccines for patients with autoimmune neuromuscular disease. We compared daily functioning using disease-specific patient-reported outcome measures (PROMs) before and after SARS-CoV-2 vaccinations. Methods: In this substudy of a prospective observational cohort study (Target-to-B!), patients with myasthenia gravis (MG), chronic inflammatory demyelinating polyneuropathy (CIDP), multifocal motor neuropathy (MMN), and idiopathic inflammatory myopathy (IIM) vaccinated against SARS-CoV-2 were included. Surveys of daily functioning (Myasthenia Gravis Activities of Daily Living, Inflammatory Rasch-Built Overall Disability Scale, Multifocal Motor Neuropathy Rasch-Built Overall Disability Scale, and Health Assessment Questionnaire-Disability Index) were sent before first vaccination and every 60 days thereafter for up to 12 months. Regression models were constructed to assess differences in PROM scores related to vaccination, compared to scores unrelated to vaccination. We also assessed the proportion of patients with deterioration of at least the minimal clinically important difference (MCID) between before first vaccination and 60 days thereafter. Results: We included 325 patients (median age = 59 years, interquartile range = 47-67, 156 [48%] female sex), of whom 137 (42%) had MG, 79 (24%) had CIDP, 43 (13%) had MMN, and 66 (20%) had IIM. PROM scores related to vaccination did not differ from scores unrelated to vaccination. In paired PROMs, MCID for deterioration was observed in three of 49 (6%) MG patients, of whom none reported a treatment change. In CIDP, MCID for deterioration was observed in eight of 29 patients (28%), of whom two of eight (25%) reported a treatment change. Conclusions: SARS-CoV-2 vaccination had no effect on daily functioning in patients with autoimmune neuromuscular diseases, confirming its safety in these patients
