Cold platelets for trauma-associated bleeding: regulatory approval, accreditation approval, and practice implementation-just the "tip of the iceberg".

Background: Laboratory and clinical evidence suggest that cold-stored platelets (CS-PLTs) might be preferable to room temperature platelets (RT-PLTs) for active bleeding. Ease of prehospital use plus potential hemostatic superiority led our facility to pursue approval of CS-PLTs for actively bleeding trauma patients.

Study Design And Methods: From November 18, 2013, through October 8, 2015, correspondence was exchanged between our facility, the AABB, and the US Food and Drug Administration (FDA).

First report of the point-of-care TEG: A technical validation study of the TEG-6S system.

Thrombelastography (TEG) measured by the TEG5000 Hemostasis Analyzer is an established but the labor-intensive method for assessing global hemostasis. The first true point-of-care TEG, the TEG6s system, uses resonance-frequency viscoelasticity measurements and a disposable multi-channel microfluidic cartridge to assess hemostasis and response to antiplatelet therapy. TEG assays (n = 5,100) were performed on the blood of healthy volunteers (n = 157) and patients undergoing coronary revascularization at three hospitals (n = 300).

p300 modulates nuclear morphology in prostate cancer.

Alterations in nuclear structure distinguish cancer cells from noncancer cells. These nuclear alterations can be translated into quantifiable features by digital image analysis in a process known as quantitative nuclear morphometry. Recently, quantitative nuclear morphometry has been shown to predict metastasis and biochemical recurrence of prostate cancer.

p300 in prostate cancer proliferation and progression.

Although prostate cancer (PCa) is the most frequently diagnosed cancer in males, little is known about the mechanisms involved in its progression. Recent in vitro studies suggest that coactivators of the androgen receptor play an important role in PCa progression. We have shown previously that p300 is involved in androgen receptor transactivation.
