Getting it right: optimizing transfusion management during the procedure.

There is little doubt that blood transfusions have saved many lives in cases of acute hypovolemia and anemia, but both the literature and practitioners still do not agree as to what the appropriate indicators for transfusion are in a cardiac surgical patient. Furthermore, there are those who claim that the benefit of blood transfusions has never been conclusively demonstrated, and evidence of transfusion related harm continues to accumulate. Cardiac surgical patients may be transfused not only because of bleeding but also due to hemodilution from preoperative and intraoperative intravenous fluids and pump primes in conjunction with a possible preoperative anemia.

Exploring the association between body weight, stigma of obesity, and health care avoidance.

Purpose: To explore the stigma of obesity and its effect on health care utilization, associations between self-esteem, attribution for weight, body mass index (BMI), satisfaction with medical care and the behavior of delaying/avoiding health care were examined.
