Abstract

When network products and services become more valuable as their userbase grows (network effects), this tendency can become a major determinant of how they compete with each other in the market and how the market is structured. Network effects are traditionally linked to high market concentration, early-mover advantages, and entry barriers, and in the cryptoasset market they have been used as a valuation tool too. The recent resurgence of Bitcoin has been partly attributed to network effects too. We study the existence of network effects in six cryptoassets from their inception to obtain a high-level overview of the application of network effects in the cryptoasset market. We show that contrary to the usual implications of network effects, they do not serve to concentrate the cryptoasset market, nor do they accord any one cryptoasset a definitive competitive advantage, nor are they consistent enough to be reliable valuation tools. Therefore, while network effects do occur in cryptoasset networks, they are not a defining feature of the cryptoasset market as a whole.

12. The future of refusals to deal and margin squeezes in the face of sector-specific regulation

Abstract

The relationship between refusals to deal and margin squeezes in EU competition law is complex and controversial. Although the underlying competition concerns are often similar, the legal standards to hold the two practices abusive under Article 102 TFEU are different – unlike the situation in US antitrust law. The chapter submits that the distinction between refusals to deal and margin squeezes is increasingly difficult to make in relation to newer practices, such as self-preferencing and preferential access to data. Instead of letting the applicable legal test under Article 102 TFEU depend on whether the conduct qualifies as an outright or constructive refusal to deal, the chapter suggests using the existence of a regulatory duty as the main determining factor for whether the strict Bronner criteria apply. To provide a more nuanced approach towards the assessment of indispensability, the chapter proposes to tailor its application to the market situation at stake.

19. Listeria Monocytogenes Peritonitis in a Peritoneal Dialysis Patient with Severe Heart Failure

Author

Abstract

Abstract: Listeria monocytogenes has rarely been reported to cause peritonitis in peritoneal dialysis (PD) patients. Listeriosis is usually a severe disease with a mortality rate of 20 to 40% in humans despite early antibiotic treatment. In this report we present the first case in Greece of peritonitis caused by L. monocytogenes, in a chronic PD patient with severe cardiac failure. The patient received prolonged antibiotic therapy with vancomycin and netilmicin which resulted in peritonitis resolution. Unfortunately however, the listeria infection caused decompensation of the patient’s cardiac failure and led to his death, despite appropriate antibiotic treatment. When peritoneal fluid cultures yield gram positive rods in an immune-compromised patient or on a patient with severe underlying diseases who regularly consumes dairy products, the clinical suspicion of this rare infection must be immediately evaluated. Listeriosis can be fatal despite effective antibiotic therapy, since it affects patients with severe underlying pathologies.

25. Individuals with Schizophrenia and Relevant Psychotic Disorders: A Clinical Population with Increased Incidence for Involuntary Admission Due to Suicidal Behavior

[0000-0003-2708-1851], and Stylianou, Konstantinos [0000-0003-3678-9421]

Abstract

Objective: Investigation of socio-demographic and clinical characteristics of individuals involuntary admitted in the Psychiatric Hospital of Cyprus with suicidal behavior. Material and Method: A descriptive correlation study with cross-sectional comparisons was performed in a sample of 40 individuals (Sampling period 12/2016-02/2018). Data collection was conducted via individual interviews using a structured questionnaire, encompassing demographic and clinical characteristics, along with the PANSS, HAM-D, YMRS and HAM-A scales to assess the intensity of psychotic, depressive, manic and anxiety symptoms. Results: The majority of the sample were Greek-Cypriots, 32 males and 8 females, between 25-34 years. 26 of them had a positive history of substance use, while 20 of them were meeting criteria for dual diagnosis. The most frequent clinical diagnosis was schizophrenia (15%) and relevant psychotic disorders (65%). The most common symptom coexisting with suicidal behavior was substance abuse (50%), while 35% of sample reported no adherence to medication during the period before suicidal behavior. The most frequent methods of suicide attempt were fall from height (20%) and overdose (20%). Positive history of substance use was positively and strongly associated with suicidal behavior (x², p&lt 0.001, Cramer's V=0.629), as well as the type of admission diagnosis (x², p&lt 0.05, Cramer's V=0.443), since individuals with schizophrenia and other psychotic disorders seemed to have increased risk for suicidal behavior than individuals with mood disorders. Overall, those involuntary admitted in the Psychiatric hospital of Cyprus because of suicidal behavior were more often Greek-Cypriot males, of secondary education, Orthodox Christians, single, aged 25-34 years, residents of urban areas (districts of Nicosia and Limassol), for the first time involuntary admitted in the psychiatric hospital, with a positive history of substance use, mainly cannabis, meeting criteria for dual diagnosis, with no family history of psychiatric disorders. Conclusions: This study demonstrates for the first time the socio-demographic and clinical characteristics of individuals involuntary admitted in the psychiatric hospital of Cyprus due to suicidal behavior. Reappraisal of the effectiveness of community-based interventions related to education on substance use and medication adherence are recom- mended, with special focus on individuals diagnosed with schizophrenia and psychotic disorders. Prevention of substance use, as well as adherence to treatment is vital to mitigate relapses or/and suicidal behavior in individuals with schizophrenia and other psychotic disorders. 58 2 150 162

Abstract

We report a case of a 51-year-old Caucasian man referred at our department due to acute renal failure (ARF) complicating respiratory failure during hospitalization in a regional hospital. The patient was previously started on steroids due to the suspicion of rapidly progressive glomerulonephritis (RPGN) in the context of Goodpasture syndrome. However, clinical and laboratory findings did not support this diagnosis; instead a careful evaluation limited differential diagnosis of the renal insult to acute tubular necrosis or acute interstitial nephritis (AIN) following respiratory infection. With lung function fully improved but renal function not recovering, a renal biopsy revealed AIN, a finding leading to further diagnostic testing and finally to the diagnosis of Legionnaires’ disease as a cause of this patient’s pulmonary-renal syndrome. The management consisted of progressive tapering of oral steroids associated with full recovery of the patient’s renal function. This is a rare case of Legionnaires’ disease causing immune-mediated AIN and highlights the possibility of Legionella infection as a cause of pulmonary-renal syndrome.
