Intestinal Cells Surprisingly Active In Pursuit Of Nutrition And Defense
Every cell lining the small intestine bristles with thousands of tightly packed microvilli that project into the gut lumen, forming a brush border that absorbs nutrients and protects the body from intestinal bacteria. In the June 29, 2009 issue of the Journal of Cell Biology, Matthew McConnell, Matthew Tyska, and colleagues now find that microvilli extend their functional reach even further using a molecular motor to send vesicles packed with gut enzymes out into the lumen to get a head start on breaking down their substrates.

Canadians Watch U.S. Reform Effort Closely
American health care reform has become a "hot topic north of the border," the Washington Times reports. "If Mr. Obama succeeds, the U.S. could draw even more Canadian doctors and nurses to the U.S., exacerbating a shortage of medical professionals, said Dr. Brian Day, a Canadian health care critic and former head of the Canadian Medical Association. If Mr. Obama fails, perhaps Canada could open its system to "medical tourism" from the U.S., Dr. Day said." Under the Canadian system, everyone is insured and has "access to basic health care without ever seeing a doctor or hospital bill." But 70% of Canadians also have "some form of supplemental health insurance," in part because of long wait times for tests and treatments under the government plan. For Canadian citizens who become ill in the U.S., it is often cheaper to "ride on a private Lear jet back to Canada" than to be treated in a U.S. hospital.

Atrial Fibrillation Linked To Increased Hospitalization In Heart Failure Patients

Patients with atrial fibrillation, common in those with advanced chronic heart failure, have an increased risk of hospitalization due to heart failure, according to new research from researchers at the University of Alabama at Birmingham (UAB). The findings, published in June in the European Heart Journal, also suggest that atrial fibrillation is not associated with an increased risk of death in heart failure patients, contradicting previous assumptions. "Our findings show that the presence of atrial fibrillation in heart failure patients did not increase their risk of death, as has been previously suggested, but did increase the risk of hospitalization due to worsening heart failure," said Mustafa Ahmed, M.D., a physician-scientist at the UAB American Board of Internal Medicine Research Pathway Program and the study"s lead investigator. Atrial fibrillation is a condition with irregular heart rhythm and is often accompanied by increased heart rate. "Importantly, atrial fibrillation significantly increased hospitalization due to heart failure only in patients not receiving a beta-blocker or drugs that block the beta-receptors in the heart but not in those receiving a beta-blocker," said Ali Ahmed, M.D., MPH, associate professor in the division of gerontology, geriatrics and palliative care medicine, director of UAB"s Geriatric Heart Failure Clinic and the study"s senior investigator. "In patients with heart failure and atrial fibrillation, beta-blockers, which help reduce heart rate, may be useful in reducing the risk of hospitalization due to worsening heart failure." Ahmed and colleagues matched 487 pairs of heart failure patients with and without atrial fibrillation from the Beta-Blocker Evaluation of Survival Trial. All-cause mortality occurred in 38 percent of the patients with atrial fibrillation against 37 percent of patients without. However, 44 percent patients with atrial fibrillation were hospitalized for worsening heart failure over the course of the trial, against only 38 percent without. The research was supported through a grant from the National Heart, Lung and Blood Institute, one of the National Institutes of Health, and a generous gift from Ms. Jean B. Morris of Birmingham, Alabama. Ahmed"s co-researchers were Mustafa Ahmed, M.D., James Ekundayo, M.D., DrPH, Inmaculada Aban, Ph.D., Bo Liu, MB, MPH, all from UAB; Michel White, MD, Montreal Heart Institute; Thomas Love, Ph.D., Case Western Reserve University; and Wilbert Aronow, MD, New York Medical College.
