Abstract

The paper examines the competition between traditional TV and Video OTT platforms in Greece. The niche theory has been adopted in order to measure users' gratification fulfilled by TV and OTTs, the competition superiority of each media and the similarity of those two media across seven aspects of gratification. An online survey conducted during first months of 2022 and 355 total feedbacks has been collected. Video OTTs score higher in six dimensions of gratification than TV, except financial benefit. Regarding niche overlap, results show that those media share close levels of similarity in information, ease of use and convenience. OTT's exceed TV in five dimensions of gratification. The highest score on the overall findings of competition superiority is in relaxation, while TV exceeds in financial benefit and information.

Abstract

Lubiprostone, a bicyclic fatty acid chloride channel activator, is efficacious in treatment of chronic constipation and constipation-predominant irritable bowel syndrome. The study aim was to compare effects of lubiprostone and placebo on colonic sensory and motor functions in humans. In double-blind, randomized fashion, 60 healthy adults received three oral doses of placebo or 24 [micro]g lubiprostone per day in a parallel-group, placebo-controlled trial. A barostat-manometry tube was placed in the left colon by flexible sigmoidoscopy and fluoroscopy. We measured treatment effects on colonic sensation and motility with validated methods, with the following end points: colonic compliance, fasting and postprandial tone and motility indexes, pain thresholds, and sensory ratings to distensions. Among participants receiving lubiprostone or placebo, 26 of 30 and 28 of 30, respectively, completed the study. There were no overall effects of lubiprostone on compliance, fasting tone, motility indexes, or sensation. However, there was a treatment-by-sex interaction effect for compliance (P = 0.02), with lubiprostone inducing decreased fasting compliance in women (P = 0.06) and an overall decreased colonic tone contraction after a standard meal relative to fasting tone (P = 0.014), with greater effect in women (P < 0.01). Numerical differences of first sensation and pain thresholds (P = 0.11 in women) in the two groups were not significant. We concluded that oral lubiprostone 24 [micro]g does not increase colonic motor function. The findings of decreased colonic compliance and decreased postprandial colonic tone in women suggest that motor effects are unlikely to cause accelerated colonic transit with lubiprostone, although they may facilitate laxation. Effects of lubiprostone on sensitivity deserve further study. tone; compliance; threshold; trial; constipation; irritable bowel

Abstract

Background: The aim of this study was to investigate the presence of IgG antiplatelet (anti-P) IgG antibodies in patients with chronic liver disease (CLD) of diverse but well defined etiology., Methods: One-hundred fifty-six consecutive patients with CLD (65 with chronic hepatitis B, 57 with chronic hepatitis C, 23 with alcoholic liver disease and 11 with primary biliary cirrhosis), and 240 healthy blood donors were investigated for the presence of anti-P antibodies., Results: Anti-P antibodies were present in 36.5% (57/156) of patients with CLD, and 2.9% (7/240) of controls (P=0.0001). In detail, anti-P antibodies were detected in 35.4% (23/65) of patients with chronic hepatitis B, 26.3% (15/57) of patients with chronic hepatitis C, 47.8% (11/23) of patients with alcoholic liver disease and 72.7% (8/11) of those with primary biliary cirrhosis. The study also demonstrated the significantly higher prevalence of anti-P antibodies in patients with cirrhosis (53.0%) than in non cirrhotic patients (26.4%, P=0.0018). The association of anti-P antibodies with thrombocytopenia was inconsistent., Conclusions: This study showed a high prevalence of anti-P IgG antibodies in patients with CLD compared to healthy controls.
