Any circumstance that disrupts the dialogue risks pregnancy problems. A new look at how stress impacts on pregnancy involves its adverse effects on the key pregnancy hormones of progesterone and prolactin. These effects have far-reaching consequences on pregnancy maintenance, maternal anxiety and embryo programming. This review focuses on early pregnancy and how stress might compromise the multi-layer, two-way communication between mother and embryo. (C) 2010 Elsevier Inc. All rights reserved.”
“Objectives: We assessed whether fibrinogen concentrate as targeted first-line hemostatic therapy

was more effective than placebo or a standardized transfusion algorithm in controlling coagulopathic bleeding in patients undergoing major aortic surgery.

Methods: In this single-center, GW786034 manufacturer prospective, double-blind study, adults undergoing Selleck Paclitaxel elective thoracic or thoracoabdominal aortic replacement surgery involving cardiopulmonary bypass were randomized to intraoperative fibrinogen concentrate (n = 29)

or placebo(n = 32). Study medication was given if patients had clinically relevant coagulopathic bleeding, measured by 5-minute bleeding mass, after cardiopulmonary bypass removal, protamine administration, and surgical hemostasis. Fibrinogen concentrate dosing was individualized using the thromboelastometric FIBTEM test. If bleeding continued, a standardized transfusion algorithm was followed. In the placebo group, all 32 patients received 1 transfusion cycle of fresh-frozen plasma/platelets, and 30 patients required a second transfusion cycle; none of these patients received any other procoagulant therapy. Rocuronium bromide Change in bleeding rate after treatment was compared using t tests.

Results: Mean change in bleeding rate after fibrinogen concentrate was – 48.3 g/5 min, compared with 0.4 g/5 min after

placebo (P <. 001), – 16.1 g/5 min after 1 transfusion cycle (fresh-frozen plasma or platelets; P = .003), and -28.0 g/5 min after 2 transfusion cycles (fresh-frozen plasma and platelets; P = .11). Reductions in bleeding rate were greater for patients with higher bleeding rates before treatment, especially with fibrinogen concentrate.

Conclusions: FIBTEM-guided intraoperative hemostatic therapy with fibrinogen concentrate is more effective than placebo in controlling coagulopathic bleeding during major aortic replacement surgery. Fibrinogen concentrate is also more effective than 1 cycle of fresh-frozen plasma/platelets and is more rapid than-and at least as effective as-2 cycles of fresh-frozen plasma/platelets.
