Could radiofrequency ablation replace liver resection for small hepatocellular carcinoma in patients with compensated cirrhosis?
The current study shows that for small HCC in the presence of compensated cirrhosis, surgical resection gives better results than radiofrequency, both in terms of overall survival, as well as disease-free survival. Further evidence is required to clarify the role of ablative therapy as a curative treatment and whether it can replace surgery.
The response to moderate exercise of formerly preeclamptic women with a subnormal plasma volume differs from that in healthy parous controls with a normal plasma volume and suggests a lower capacity to raise venous return in conditions of a higher demand for systemic flow. The lower capacity to raise venous return in these conditions is associated with more cardiovascular drift. The physiologic consequence is a lower aerobic endurance performance during moderate exercise.
