A randomised, double-blind, placebo-controlled trial of trichuris suis ova in active crohn's disease
(2017)
BACKGROUND AND AIMS To investigate the efficacy and safety of three different dosages of embryonated, viable eggs of Trichuris suis [TSO] versus placebo for induction of remission in mildly-to-moderately active ileocolonic, uncomplicated Crohn's disease [CD].
METHODS Adults with active CD [n = 252] randomly received six fortnightly doses of 250, 2500, or 7500 TSO/15 ml suspension/day [TSO 250, TSO 2500, TSO 7500], or 15 ml placebo solution/day, in a double-blind fashion, with 4 weeks' follow-up. Primary endpoint was the rate of clinical remission [Crohn's Disease Activity Index [CDAI] < 150] at end of treatment, ie at Week 12 or withdrawal. Secondary endpoints included the course of clinical remission, rate of clinical response, change in CDAI, change in markers of inflammation, mucosal healing, and Physician's Global Assessment.
RESULTS Clinical remission at Week 12 occurred in 38.5%, 35.2%, and 47.2% of TSO 250, TSO 2500, and TSO 7500 patients, respectively, and in 42.9% of placebo recipients. TSO induced a dose-dependent immunological response. There was no response regarding laboratory markers of inflammation. Other secondary efficacy variables also showed no advantage of TSO over placebo for treatment of active CD. Administration of TSO did not result in any serious adverse drug reaction. Review of non-serious suspected adverse drug reactions following TSO did not reveal any safety concerns.
CONCLUSIONS Administration of 250-7500 TSO fortnightly over 12 weeks was safe and showed a dose-dependent immunological response, but no TSO dose showed a clinically relevant effect over placebo for induction of clinical remission or response in mildly-to-moderately active, ileocolonic CD.
Anomalous monism and mental causality : on the debate of Donald Davidson’s philosophy of the mental
(2004)
The English version of the first chapter of Erwin Rogler and Gerhard Preyer: Materialismus, anomaler Monismus und mentale Kausalität. Zur gegenwärtigen Philosophie des Mentalen bei Donald Davidson und David Lewis (2001) "Anomaler Monismus und Mentale Kausalität. Ein Beitrag zur Debatte über Donald Davidsons Philosophie des Mentalen" is a contribution to the current debates on the philosophy of the mental and mental causality initiated from Donald Davidson's philosophy with his article "Mental Events" (1970). It is the intent of the English version to give a response to the controversy among American, British and Australian philosophers in the context of a global exchange of ideas on problems understanding the mental. Contents 1. Preliminary Remarks 2. The Critique of Property-Epiphenomenalism and Counterarguments (a) The Enlargement of Nomological Reasoning (b) The Counterfactual Analysis (c) Supervenient Causality 3. Are Mental Properties real or unreal (fictive)? Abstract Things and events are fundamental entities in Davidson's ontology. Less distinct is the ontological status of properties, especially of mental types. Despite of some eliminative allusions there are weighty reasons to understand Davidson's philosophy of mind as including intentional realism. With it, the question of mental causality arises. There are two striking solutions to this problem: the epiphenomenalism of mental properties and the downward causation of mental events. Davidson cannot accept either. He claims to justify the mental as supervenient causality in order to thus integrate it into physicalism (his version of monism). But his argument at best proves the explanatory, not the causal relevance of mental properties. For this and for other reasons, Davidson fails the aspired synthesis of a sufficiently strong physicalism and the autonomy of the mental; a project whose realization is anyhow hard to achieve.
