Preemptive use of recombinant activated factor VII: many questions but few answers

Use of biomarkers in sepsis: many questions, few answers

Why do we use biomarkers in sepsis? There are several answers to this question. Some researchers argue that biomarkers are used to assess the prognosis of septic patients, (1) but why should we use a biomarker merely to determine whether a patient has a higher risk of death when currently available interventions are not able to modify the prognosis? (2) As we all know, dozens of randomized cont...

Osteopathic manipulative treatment for pandemic influenza: many questions, few answers

In this volume, an article by Hruby and Hoffman titled "Avian influenza: an osteopathic component to treatment" proposes the use of osteopathic manipulative treatment (OMT) as an adjunct to other forms of therapy in the management of a potential pandemic of avian influenza or "bird flu" [1]. This article is certainly timely and presents a much-needed reminder of the potential use of OMT in the ...

Percolation beyond Z D , Many Questions and a Few Answers

A comprehensive study of percolation in a more general context than the usual Z d setting is proposed, with particular focus on Cayley graphs, almost transitive graphs, and planar graphs. Results concerning uniqueness of innnite clusters and inequalities for the critical value p c are given, and a simple planar example exhibiting uniqueness and non-uniqueness for diierent p > p c is analyzed. N...

Percolation beyond Zz, Many Questions and a Few Answers

A comprehensive study of percolation in a more general context than the usual Z d setting is proposed, with particular focus on Cayley graphs, almost transitive graphs, and planar graphs. Results concerning uniqueness of infinite clusters and inequalities for the critical value pc are given, and a simple planar example exhibiting uniqueness and non-uniqueness for different p > pc is analyzed.
