Effects of Topically Administered Neuroprotective Drugs in Early Stages of Diabetic Retinopathy:Results of the EUROCONDOR Clinical Trial

The primary objective of this study was to assess whether the topical administration of two neuroprotective drugs (brimonidine and somatostatin) could prevent or arrest retinal neurodysfunction in patients with type 2 diabetes. For this purpose, adults aged between 45 and 75 years with a diabetes duration ≥5 years and an Early Treatment of Diabetic Retinopathy Study (ETDRS) level of ≤35 were randomly assigned to one of three arms: placebo, somatostatin, or brimonidine. The primary outcome was the change in implicit time (IT) assessed by multifocal electroretinography between baseline and at the end of follow-up (96 weeks). There were 449 eligible patients allocated to brimonidine (n = 152), somatostatin (n = 145), or placebo (n = 152). When the primary end point was evaluated in the whole population, we did not find any neuroprotective effect of brimonidine or somatostatin. However, in the subset of patients (34.7%) with preexisting retinal neurodysfunction, IT worsened in the placebo group (P < 0.001) but remained unchanged in the brimonidine and somatostatin groups. In conclusion, the topical administration of the selected neuroprotective agents appears useful in preventing the worsening of preexisting retinal neurodysfunction. This finding points to screening retinal neurodysfunction as a critical issue to identify a subset of patients in whom neuroprotective treatment might be of benefit

A Theory of Ageements in the Shadow of Conflict: The Genesis of Bargaining Power

We present a novel approach to N-person bargaining, based on the idea that the agreement reached in a negotiation is determined by how the direct conflict resulting from disagreement would be resolved. Our basic building block is the disagreement function, which maps each set of feasible outcomes into a disagreement point. Adding this function to the description of a bargaining problem, a weak axiom based on individual rationality leads to a unique solution: the agreement in the shadow of conflict, ASC. This agreement may be construed as the limit of a sequence of partial agreements, each of which is reached as a function of the parties' relative power in the disagreement scenario. As a result, we identify a link between the circumstances of bargaining and the bargaining powers within it. The rich get the law passed by means of force and arms or get it accepted by fear to their might, aren't things this way?
