Dialysis: when to start or when to stop?

Sir, There have been several recent discussions around the timing of initiation of dialysis [1,2]. There remains little scientific consensus on when to start and on which clinical and biochemical parameters we base this decision. In the broadest sense, dialysis should serve to decrease morbidity and/or mortality whilst maintaining or improving quality of life. It is almost assumed that renal re...

When to Start Antiretroviral Therapy

The question of when to start combination antiretroviral therapy for treatment-naïve patients has always been controversial. This is particularly true in the current era, with major guidelines recommending very different treatment strategies. Despite a lack of clarity regarding the optimal time to begin therapy, there has been a recent shift toward earlier initiation. This more aggressive appro...

When Regions Start to Move

In this paper, we discuss a formalism for modeling regions that are exposed to movement or deformation. The basis of our formalism is the RCC theory, which uses topological relations between regions to reason about them. By using fuzzy set theory and the notion of conceptual neighbors, we are able to deal with regions that can move or change over time. In addition, we introduce an algorithm for...

The optimal time to start antiretroviral therapy (ART) for human immunodeficiency virus (HIV)-infected individuals remains uncertain. Although current ART regimens are effective in suppressing viremia and enhancing immune function and are increasingly convenient and well tolerated, ongoing concerns remain about adherence, drug-related toxicities, drug resistance, and cost. Although few clinical...
