Current Canadian approaches to dialysis for acute renal failure in the ICU.
2002
American journal of nephrology
Hyman A, Mendelssohn DC
Plain English This study looked at how hospitals in Canada treat acute kidney failure in critically ill patients using dialysis. Researchers found that the use of continuous renal replacement therapy (CRRT) has increased significantly from 9% to 26% over the past five years, while other dialysis methods, like intermittent hemodialysis, have become less common. Despite the rise in CRRT's popularity, most hospitals do not track the effectiveness of their dialysis approaches, and there isn't a clear agreement on the best treatment, which is important because more effective dialysis could lower the high death rate of over 50% associated with acute kidney failure.

Researchers found that kinetochores, the parts of chromosomes that connect to a structure called the spindle, are essential for moving chromosomes properly. They also discovered that parts of the chromosomes can stabilize the spindle on their own, making the process more efficient. This research is important because understanding how cell division works can lead to better insights into diseases like cancer, where cell division goes wrong.

Adrenomedullin dilates rat pulmonary artery rings during hypoxia: role of nitric oxide and vasodilator prostaglandins.
1996
Journal of cardiovascular pharmacology
Yang BC, Lippton H, Gumusel B, Hyman A, Mehta JL
Plain English This study looked at how a peptide called adrenomedullin (ADM) affects the relaxation of blood vessels in rats, especially during low-oxygen conditions (hypoxia). Researchers found that ADM made the pulmonary arteries relax much more than the aorta under normal oxygen levels, with about a one-third decrease in relaxation during hypoxia. The key takeaway is that while ADM can help relax these blood vessels, its effectiveness decreases when oxygen levels are low.
Who this helps: This research benefits patients with pulmonary arterial hypertension.
