Adaptive mutation mechanism may drive some forms of antibiotic resistance

Retromutagenesis resolves the puzzle: if cells aren’t growing because they’re under stress, which means their DNA isn’t being copied, how do the new mutants appear? The answer: a mutation appears in the RNA first. Despite its name, retromutagenesis does not involve reverse transcriptase.

Emory Cardiologist Weighs in on U.S. News Diet Ranking

 

Laurence Sperling, MD

U.S. News & World Report recently announced the results of its first-ever Best Diets rankings evaluating some of the country’s most popular diets.

Emory Heart & Vascular Center cardiologist Laurence Sperling served on a panel of 22 health experts selected by U.S. News to help develop the rankings. Sperling is the medical director of the Emory Heartwise Risk Reduction Program and professor of medicine at Emory University School of Medicine.

Sperling and his panel colleagues reviewed information about 20 well-known diets, from Atkins to Zone, and rated each one on specific measures such as safety, easiness to follow and nutritional completeness.

Using the experts’ ratings, U.S. News developed five diet categories to address a broad range of consumers’ dieting goals and needs including Best Diabetes Diets, Best Heart Diets, Best Weight Loss Diets and Best Overall. “The goal of the Best Diets rankings is to help consumers find authoritative guidance on healthful diets that will work for them over the long haul,” said Lindsay Lyon, U.S. News‘s Health News Editor.

Weight Watchers ranked first in the Weight Loss category. Tied for number two were Jenny Craig and the Raw Food Diet, an approach that challenges dieters to avoid foods that have been cooked.

The government-endorsed DASH Diet took the top spot as the best diet overall. Three diets tied at number two, excelling in all measures U.S News considered: the Mediterranean Diet, the TLC Diet, and Weight Watchers.

Cholesterol levels improve with nut consumption

Improvements in blood cholesterol levels are linked with eating nuts, according to this week’s Archives of Internal Medicine.

Nuts are good for your heart

Authors writing in the journal say that dietary interventions to lower blood cholesterol concentrations and to modify blood lipoprotein levels are the cornerstone of prevention and treatment plans for coronary heart disease.

Nuts are rich in plant proteins, fats (especially unsaturated fatty acids), dietary fiber, minerals, vitamins and other compounds, such as antioxidants and phytoesterols. The contents of nuts are a focus because of the potential to reduce coronary heart disease risk and to lower blood lipid – fat and cholesterol – levels.

Emory University’s Cheryl Williams, RD, LD, clinical nutritionist, Emory Heart & Vascular Center, Emory HeartWise Cardiac Risk Reduction Program, says nuts are among the heart healthiest whole foods as they provide a variety of health promoting compounds such as dietary fiber, vitamins (vitamin E), minerals (selenium), antioxidants and phytoesterols.

While most of the calories provided from nuts come from fat, notes Williams, it is mostly unsaturated fats (mono and polyunsaturated), which have been shown to help lower elevated serum cholesterol, and to some extent triglyceride levels (via omega 3 fatty acids provided from walnuts).

Heart Month: Helping narrowed aortic valves

Celebrating February’s American Heart Month at Emory Heart & Vascular Center

Emory cardiologists are using a promising new non-surgical treatment option for patients with severe aortic stenosis.

Emory University Hospital is one of about 20 hospitals nationwide, and the only site in Georgia, to study this new technology – with 75 patients receiving new valves at Emory since the clinical trial started in October 2007. Researchers hope to receive U.S. Food and Drug Administration approval in late 2011.

The life threatening heart condition affects tens of thousands of Americans each year when the aortic valve tightens or narrows, preventing blood from flowing through normally.

Peter Block, MD

Peter Block, MD, professor of medicine, Emory School of Medicine, and colleagues are performing percutaneous aortic valve replacement as part of a Phase II clinical trial, comparing this procedure with traditional, open-heart surgery or medical therapy in high-risk patients with aortic stenosis.

The procedure provides a new way for doctors to treat patients who are too ill or frail to endure the traditional surgical approach.

During the procedure, doctors create a small incision in the groin or chest wall and then feed the new valve, mounted on a wire mesh on a catheter, and place it where the new valve is needed.

Emory Heart & Vascular Center advances medicine

American Heart Month 2010

Learn about Emory Heart & Vascular Center advances during American Heart Month.

Research led by John Puskas, MD, professor of surgery and associate chief, Division of Cardiothoracic Surgery, Emory School of Medicine, has shown that off-pump bypass surgery reduces the risk of complications for high-risk patients, such as those that are especially frail or those with diabetes, obesity, kidney disease or a history of stroke.

This conclusion comes from a 10-year history of coronary bypass patients at Emory recently published in the Annals of Thoracic Surgery.

Puskas also recently presented long-term follow-up data from the first randomized U.S. trial to compare off-pump with conventional on-pump surgery.

The results from the landmark SMART (Surgical Management of Arterial Revascularization) study, which started in 2000, show that participants who had the off-pump procedure lost less blood, had less damage to their hearts during surgery and recovered more quickly than those who underwent on-pump surgery.

Beating-heart patients in the study also were able to breathe on their own sooner after surgery, spent less time in intensive care and left the hospital one day sooner, on average, than conventional coronary bypass patients.
