    Distribuierte Systeme, wie die Bitcoin-Blockchain, stellen das Recht vor neue Herausforderungen. Das disruptive Potential liegt unter anderem im Fehlen einer zentralen, verantwortlichen Kontrollinstanz, an die das Recht traditionell anknĂŒpft, und im Verschwimmen der Rollen von „ProduzentInnen“ und „KonsumentInnen“ innerhalb des Systems. Die Erzeugung von KryptowĂ€hrungen, wie Bitcoin, mittels „Proof of Work“ und die gleichzeitige Validierung von Transaktionen zwischen NetzwerknutzerInnen (sog „Mining“) ist ein Beispiel dafĂŒr, dass die rechtlich etablierten Kategorien heute fĂŒr eine effiziente Rechtsdurchsetzung unzureichend sind. „Mining“ kann rechtlich zwar als GlĂŒcksspiel iSd österreichischen GSpG eingeordnet werden. Konsequenz dieser Einordnung sind allerdings Probleme beim Vollzug des folglich anwendbaren Ordnungs-, Abgaben- und Strafrechts. Daraus wird geschlossen, dass die Regulierung von „Peer to Peer“-Systemen neue LösungsansĂ€tze erfordert, sodass dem Staat seine rechtliche Steuerungsfunktion erhalten bleibt.Distributed ledgers, such as the Bitcoin blockchain, create new challenges for authorities and legislators alike. The technology is considered disruptive due to the lack of a responsible legal entity and because the lines are blurred between the “producers” and “consumers” operating within it. The creation of cryptocurrencies, like Bitcoin, through “proof of work” and the simultaneous validation of transactions between users of the network (so called “mining”) perfectly illustrate how established legal categories are insufficient to achieve effective law enforcement at present. This paper shows that according to Austrian law, “mining” qualifies as a gamble. In that case, the applicable provisions of Austrian regulatory, tax and criminal law are, however, hardly enforceable. It follows that the regulation of “peer to peer”-systems requires an innovative approach, in order for the state to remain a key player in managing society

    Pre-ictal heart rate variability alterations in focal onset seizures and response to vagus nerve stimulation

    Purpose: Vagus nerve stimulation (VNS) is an effective and well-known treatment for drug resistant epilepsy (DRE) patients since 1997, yet prediction of treatment response before implantation is subject of ongoing research. Neuroimaging and neurophysiological studies investigating the vagal afferent network in resting state documented that differences in between epilepsy patients were related to treatment response. This study investigated whether an event-related parameter, pre-ictal heart rate variability (HRV) is associated with response to VNS therapy. Methods: DRE patients underwent video-electroencephalography (EEG) recording before VNS implantation. HRV parameters (time, non-linear and frequency domain) were assessed for every seizure during two 10 min time frames: baseline (60 min before seizure onset) and pre-ictal (10 min before seizure onset). Pre-ictal HRV parameter alterations were correlated with VNS response after one year of VNS therapy and seizure characteristics (temporal/extratemporal, left/right or bilateral). Results: 104 seizures from 22 patients were evaluated. Eleven patients were VNS responders with a seizure frequency reduction of > 50 % after one year of VNS. In VNS responders no changes in HRV parameters were found while in VNS non-responders the time domain and non-linear HRV variables decreased significantly (p = 0.024, p = 0.005, p = 0.005) during the pre-ictal time frame. 10/11 VNS non-responders had a seizure lateralization to the left compared to 4/11 VNS responders. Conclusion: VNS non-responders were characterized by a significant decrease of pre-ictal HRV (time domain/nonlinear variables) suggesting a sudden autonomic imbalance probably due to an impaired central autonomic function that makes it at the same time unlikely to respond to VNS

    Comparative risk of major congenital malformations with eight different antiepileptic drugs: a prospective cohort study of the EURAP registry

    Background: Evidence for the comparative teratogenic risk of antiepileptic drugs is insufficient, particularly in relation to the dosage used. Therefore, we aimed to compare the occurrence of major congenital malformations following prenatal exposure to the eight most commonly used antiepileptic drugs in monotherapy. Methods: We did a longitudinal, prospective cohort study based on the EURAP international registry. We included data from pregnancies in women who were exposed to antiepileptic drug monotherapy at conception, prospectively identified from 42 countries contributing to EURAP. Follow-up data were obtained after each trimester, at birth, and 1 year after birth. The primary objective was to compare the risk of major congenital malformations assessed at 1 year after birth in offspring exposed prenatally to one of eight commonly used antiepileptic drugs (carbamazepine, lamotrigine, levetiracetam, oxcarbazepine, phenobarbital, phenytoin, topiramate, and valproate) and, whenever a dose dependency was identified, to compare the risks at different dose ranges. Logistic regression was used to make direct comparisons between treatments after adjustment for potential confounders and prognostic factors. Findings: Between June 20, 1999, and May 20, 2016, 7555 prospective pregnancies met the eligibility criteria. Of those eligible, 7355 pregnancies were exposed to one of the eight antiepileptic drugs for which the prevalence of major congenital malformations was 142 (10·3%) of 1381 pregnancies for valproate, 19 (6·5%) of 294 for phenobarbital, eight (6·4%) of 125 for phenytoin, 107 (5·5%) of 1957 for carbamazepine, six (3·9%) of 152 for topiramate, ten (3·0%) of 333 for oxcarbazepine, 74 (2·9%) of 2514 for lamotrigine, and 17 (2·8%) of 599 for levetiracetam. The prevalence of major congenital malformations increased with the dose at time of conception for carbamazepine (p=0·0140), lamotrigine (p=0·0145), phenobarbital (p=0·0390), and valproate (

    Clinical and genetic characteristics of late-onset Huntington's disease

    Background: The frequency of late-onset Huntington's disease (>59 years) is assumed to be low and the clinical course milder. However, previous literature on late-onset disease is scarce and inconclusive. Objective: Our aim is to study clinical characteristics of late-onset compared to common-onset HD patients in a large cohort of HD patients from the Registry database. Methods: Participants with late- and common-onset (30–50 years)were compared for first clinical symptoms, disease progression, CAG repeat size and family history. Participants with a missing CAG repeat size, a repeat size of ≀35 or a UHDRS motor score of ≀5 were excluded. Results: Of 6007 eligible participants, 687 had late-onset (11.4%) and 3216 (53.5%) common-onset HD. Late-onset (n = 577) had significantly more gait and balance problems as first symptom compared to common-onset (n = 2408) (P <.001). Overall motor and cognitive performance (P <.001) were worse, however only disease motor progression was slower (coefficient, −0.58; SE 0.16; P <.001) compared to the common-onset group. Repeat size was significantly lower in the late-onset (n = 40.8; SD 1.6) compared to common-onset (n = 44.4; SD 2.8) (P <.001). Fewer late-onset patients (n = 451) had a positive family history compared to common-onset (n = 2940) (P <.001). Conclusions: Late-onset patients present more frequently with gait and balance problems as first symptom, and disease progression is not milder compared to common-onset HD patients apart from motor progression. The family history is likely to be negative, which might make diagnosing HD more difficult in this population. However, the balance and gait problems might be helpful in diagnosing HD in elderly patients
