Low-fat diets, move over. When it comes to lowering cholesterol, a “portfolio” diet that includes cholesterol-lowering foods such as oatmeal, nuts, and soy products is better.
Several years ago, researchers at St. Michael’s Hospital and the University of Toronto created what they called a “dietary portfolio of cholesterol-lowering foods.” It went after cholesterol by adding to a heart-healthy diet specific foods known to lower cholesterol: margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.
In a head-to-head test against the low-fat diet traditionally recommended by the American Heart Association, the portfolio approach was the clear winner. (You can see the makeup of the test diet here.) After 24 weeks, it lowered harmful LDL cholesterol by 13%, while the low-fat diet lowered LDL by only 3%. As an added benefit, the portfolio approach also lowered triglycerides and blood pressure, and did not depress the level of beneficial HDL cholesterol. The results were published in the Journal of the American Medical Association.
What I appreciate about this study is that it Read more »

Eating a lot of chocolate was associated with a 37% reduction in cardiovascular disease and a 29% reduction in stroke compared eating less, researchers reported. But, people are trending toward record obesity by the year 2030, which is a cardiometabolic risk in its own right.
Willie Wonka’s factory wasn’t the only risky place for those with a sweet tooth.
In the first study, to evaluate the association of chocolate with the risk of developing cardiometabolic disorders, researchers performed a meta-analysis of randomized trials, six cohort and one cross-sectional, which reported the association between chocolate and the risk of cardiovascular disease (coronary heart disease and stroke), diabetes, and metabolic syndrome for about 114,000 people.
Because the studies reported chocolate consumption differently, researchers Read more »

Several questionable sources are spreading alarms about the possible dangers of prenatal ultrasound exams (sonograms). An example is Christine Anderson’s article on the ExpertClick website. In the heading, it says she “Never Liked Ultrasound Technology.”
[She] has never been sold on the safety using Ultrasounds for checking on the fetuses of pregnant women, and for the last decade her fears have been confirmed with a series of studies pointing to possible brain damage to the babies from this technology.
Should We Believe Her?
Should we avoid ultrasounds because Anderson never liked them? Should we trust her judgment that her fears have been confirmed by studies? Who is she?
“Dr.” Christine Anderson is a pediatric chiropractor in Hollywood who believes a lot of things that are not supported by science or reason. Her website mission statement includes
We acknowledge the devastating effects of the vertebral subluxation on human health and therefore recognize that the spines of all children need to be checked soon after birth, so they may grow up healthy.
It also states that “drugs interfere… and weaken the mind, body, and spirit.” Anderson is Read more »

Hospitals across the country are working on quality initiatives to reduce re-admissions to hospitals. There are consultants, conferences, forums, meetings, physicians, nurses and administrators who are spending hours upon hours (and lots of $$$) to find ways to keep patients who have been discharged from being readmitted within 30 days. Why all of this activity? It is one of the quality measures that is being tracked by Medicare and Medical (CMS) and decreased reimbursement will be next if a patient is readmitted to any hospital within 30 days of a discharge. The diagnosis doesn’t matter.
A new study shows all of this focus and cost may not be worth it. Readmission after a hospital discharge may not be an indication of poor care.
The study, published in the Canadian Medical Association Journal looked at 4,812 patients and had medical experts review the cases of the 649 who needed urgent readmission within 6 months. (Not one month as we are measuring). They found that Read more »

I am often asked by elder persons whether or not they should take the herpes zoster (“shingles”) vaccine. Up until this point, I have been answering “yes” based on my own experience, but now there is some data to support this recommendation.
In the article, “Herpes Zoster Vaccine in Older Adults and the Risk of Subsequent Herpes Zoster Disease,” Hung Fu Tseng and his colleagues reported their findings in the Journal of the American Medical Association (JAMA 2011;305[2]:160-161). They evaluated the risk of herpes zoster after persons received the vaccine in a general practice setting.
In a retrospective (looking back at a cohort of patients from medical records) study, the researchers compared Read more »
