About 19 in every 100,000 American children under the age of five suffers from an inflammatory illness called Kawasaki Disease (KD) that can cause irreversible damage to the heart. If diagnosed early, it can usually be treated effectively, and children can be returned to health in just a few days. But between 10 and 20 percent of treated patients suffer from a persistent fever, or one that recurs after treatment, and they are at elevated risk of developing coronary artery aneurysms. A new study, led by Robert Wood Johnson Foundation (RWJF) Harold Amos Medical Faculty Development Program Scholar Adriana H. Tremoulet, MD, MAS, and published yesterday in The Lancet, offers new hope for patients with KD.
The symptoms of KD include prolonged fever associated with a rash, swollen neck glands, red eyes, swollen red lips, a condition physicians call strawberry tongue, and swollen hands and feet with peeling skin. Current treatment is infusion of intravenous immunoglobulin (IVIG) and aspirin. The IVIG carries the pooled antibodies from the blood plasma of more than 100,000 donors, and in the KD patient, it decreases the inflammation that causes heart damage. The treatment usually works, but some patients’ IVIG-resistance puts them at greater risk and in need of further treatment.
Tremoulet, a pediatric infectious disease specialist at Rady Children’s Hospital in San Diego, conducted a Phase III trial in which a synthetic antibody called infliximab was added to the standard IVIG and aspirin treatment. While the protocol did not affect the patients’ resistance, it had important positive results. “In our study,” Tremoulet said, “we demonstrated that a single dose of infliximab is safe in children with Kawasaki Disease and that this treatment reduced the inflammation in the body overall as well as in the arteries of the heart faster than just using standard treatment with intravenous immunoglobulin.”

Cardiovascular disease is the number one killer of African American women. It has become imperative for the nation to take back the reins of its health status and educate the public about this threat. The statistics are alarming. Black women are twice as likely to suffer from cardiovascular disease as women of other ethnicities. And according to the American Heart Association, cardiovascular disease kills nearly 50,000 African-American women annually. The reason for this disparity can be attributed to a lack of health knowledge, being overweight or obese, and lack of physical activity. Early intervention and action has been identified as the key to reducing this population’s risk of mortality from cardiovascular disease and related diagnoses.
Addressing and raising awareness of the health risks associated with cardiovascular diseases for African American women has been quite challenging. Recognizing this issue, Vanessa Jones Briscoe, PhD, MSN, then a Health Policy Associate at the Center for Health Policy at Meharry Medical College, developed and implemented a culturally appropriate health education program to educate minority populations about unhealthy lifestyles. It is called the “Be Heart Smart” program.

Every day, all over America, people visit their doctors with chest pain and other symptoms of coronary artery disease. Each year, more than a million of them choose to undergo bypass surgery or angioplasty. Are these decisions good ones? Even though modern medicine has committed itself to an ideal of evidence-based medicine, with its clinical trials, meta-analyses, and practice guidelines, the answer is not always clear. By looking closely at the history of these procedures, it is possible to understand some of the reasons why this is the case. With support from a RWJF Investigator Award in Health Policy Research, I looked at three specific questions: the role of evidence and intuition in medical decisions, the reasons why it can be so difficult to determine the risks of medical interventions, and the problem of “unwarranted variation” in medical practice.

At age 26, I came to the realization that I wasn’t getting any younger. With this being so obvious, you’re probably sarcastically wondering: How did she figure that out? Well, I will tell you the story. One winter morning I awakened to my left arm so numb I thought it was not my own. My arm was numb because I’d slept on it all night (I had slept this way from birth up until this point).
I visited my doctor and discussed this tragedy, he laughed as he does normally to all my hypochondriac symptoms. After he had a good chuckle he told me that because of my weight (all 210 lbs. of me), the blood flow was being cut off in my arm and caused it to go numb. He then told me that my weight could cause a number of issues I did not want to experience at 26 years of age. I went home, grabbed my computer, typed in the search bar ‘DIET’ and began my stretch of unsuccessful attempts at losing weight. I came up with this personal fact: There is no diet or exercise that will work for me if I am not willing to work for it.
Health Care Providers Shouldn’t Hit the Snooze Button When It Comes to Asking Their Patients About Sleep

Heart disease accounts for one in every four deaths in the United States—600,000 deaths per year. Prevention and treatment regimens for heart disease include important changes in lifestyle, centering primarily on alterations to diet and physical activity. Interestingly, sleep is rarely part of this discussion.
This is alarming given the growing evidence from large-scale population studies and laboratory-based experiments that demonstrate that sleep plays a larger role in heart health than originally appreciated by the medical community. For example, in a 2003 study, women with established coronary heart disease who reported poor sleep quality were more than 2.5 times more likely to go on to experience a cardiac event than good quality sleepers. Nevertheless, when it comes to asking patients about their sleep, health care providers routinely hit the snooze button.
In an effort to raise the profile of sleep as a risk factor for cardiovascular disease (CVD), my work has focused on investigating the links between sleep and the biological pathways implicated in CVD development and progression. Said another way, much of my research focuses on how sleep disturbance gets under the skin.
