For surgical patients meeting criteria for the critical RBC administration threshold (CAT) due to an associated coagulation disorder, which hemostatic resuscitation strategy (goal-directed versus ratio-based) is superior?

Novel blood products are being developed based on innovative science (e.g., ex vivo manufactured RBC and platelets, and platelet and plasma derived hemostatic products). However, there is a significant lag in the development of appropriate tools and model systems, which poses a challenge when evaluating such products for regulatory approval.

1) Phase III efficacy trials of new tuberculosis drugs (e.g., bedaquiline, delamanid, PA-824) that have shown promise in early phase studies for multidrug-resistant tuberculosis.

2) Phase III efficacy trials of new and existing tuberculosis drugs to development very short course regimens (3-4 months).

3) Phase III efficacy trials of new and existing drugs for treatment of latent tuberculosis infection in contacts of... more »

Current stem cell based approaches to translational medicine predominantly show modest efficacy. Most research rest on accepting existing limitations and focusing upon "tweaks" to the experimental model rather than taking on important barriers head on. The efficacy of stem cell-based regenerative medicine will never be fully realized unless we stop trying overly simplistic approaches such as"more is better" and start... more »
