Research led by Teresa Woodruff, PhD, director of the Institute for Women's Health Research at Northwestern University was featured in the first edition of  Horizons in Bioscience, a publication of the Federation of American Societies for Experimental Biology, that describes scientific discoveries on the brink of clinical application.   This publication is shared with members of Congress who track National Institute of Health funding.

In 2006, Dr. Woodruff coined the term 'oncofertility' to describe the merging of two fields: oncology and fertility. Advances in chemotherapy and radiation have increased survival in cancer patients but many of these life-saving treatments often result in the loss of fertility. Breakthroughs in ovarian tissue cryopreservation and in vitro follicle maturation are brightening the outlook for preserving fertility in young women with cancer and other diseases that are treated with potent therapies. Based on promising science being done in her lab, Woodruff was awarded a prestigious Roadmap Grant from the NIH to advance her work in 2007. She now heads a national Oncofertility Consortium, an interdisciplinary team of biomedical and social scientists, oncologists, pediatricians, engineers, and ethicists from universities across the country--bringing national experts together to accelerate the new field.

What is Heart Disease?

Heart Disease is a general term used to describe various diseases and syndromes of the heart and blood vessels.  Included in the definition are diseases such as coronary artery disease, heart arrhythmia, heart valve disease, heart failure, and congenital heart defects, among others.

Heart disease is the number one killer of both men and women worldwide, but may be prevented or treated with healthy lifestyle choices.  The symptoms of heart disease vary dependent on the specific condition but include chest pain, shortness of breath, fluttering in the chest, swelling in the lower limbs, and fatigue.  Symptoms of a myocardial infarction (or heart attack) tend to be different between men and women, with women experiencing more subtle symptoms such as fatigue, shortness of breath and nausea.  Consequently, it may be more difficult for health professionals to diagnose and respond to a heart attack in a woman.  In addition, recent research has shown that women suffer disproportionately than men from coronary artery disease in the small vessels (arterioles) as opposed to the larger arteries.  This may further complicate diagnosis and treatment of heart disease in women.

Causes of heart and cardiovascular disease include poor diet, little exercise, obesity, smoking, and high blood pressure, but may also be caused by congenital defects.  A healthy diet and exercise along with maintenance of blood pressure, cholesterol, and stress may help reduce the risk of heart disease.  Treatments for heart disease include lifestyle changes, medication, and in some cases surgery, and it is best treated when diagnosed early.

Earlier this week, the Federal Drug Administration (FDA) announced that they had approved a new drug for type 2 diabetes (see the FDA's press release here).  Type 2 is the most common kind of diabetes and can develop at any age despite the old misnomer that it was an "adult-onset" disease.  Essentially, your body does not properly release insulin in response to increases in blood sugar (for example, after a meal).  Therefore, sugar is not properly metabolized and builds up in your blood.

Diabetes is a huge concern not only as the seventh leading cause of deaths in America, but also in the high medical costs for  those afflicted.  Statistics show that more than half of diabetes cases are women.  Pregnant women can be affected by gestational diabetes, which typically goes away after the baby is born but can lead to the development of Type 2 diabetes.  This may contribute to the slight sex bias in Type 2 diabetes, where women comprise 58% of all cases (according to a 1995 study by the National Diabetes Data Group).  There is a nice discussion on sex-specific differences in diabetes on Medscape Today, if you are interested in reading more.  The article is accompanied by a long list of references for more detailed information.

I don't study diabetes and I'm not a doctor, but based on my limited knowledge and reading, it looks like the new drug (which will be sold as Victoza) has a different target in the pancreas than the other drugs already on the market.  (There was a nice overview in this 2001 review article in the journal Nature.)  It's nice to have more possible treatments since not all drugs work to the same effect in every patient.  There's evidence out there that some drugs act differently even between men and women!  Of course, with any new drug, time will tell if Victoza causes any long-term effects.  However, it is promising to have a new option for those dealing with diabetes and their loved ones as well.  Has diabetes affected you or someone you know in any way and if so, what has been your (or their) experience with the current drugs out there already?

The Food and Drug Administration (FDA) is warning the public about a counterfeit version of the weight-loss drug Alli 60 mg capsules (120 count refill pack) being sold over the Internet, particularly at online auction sites.
The counterfeit product is illegal and unsafe. FDA advises people who believe that they have a counterfeit product not to use the drug and to dispose of it immediately. There is no evidence at this time that the counterfeit Alli product has been sold in retail stores.

According to the FDA, the counterfeit Alli looks similar to the authentic product, with a few notable differences. Counterfeit Alli has:
* a missing LOT code on the outer cardboard packaging
* an expiration date that includes a month, day and year (real Alli only has month and year)
* plain foil for the inner safety seal without words on it (real Alli has the words "SEALED FOR YOUR PROTECTION" printed on it)
* large capsules with white powder, as opposed to small white pellets found in real Alli
* a slightly taller plastic bottle with a wider cap and coarser ribbing on cap than is seen in real Alli.

Alli is an FDA-approved, over-the-counter weight-loss drug that contains orlistat as its active ingredient. The counterfeit version does not contain orlistat, instead it is made with varying amounts of sibutramine, a stimulant drug. Although sibutramine is the active ingredient in another FDA-approved prescription weight-loss drug, it is only to be used in specific doses and under the supervision of a physician. Preliminary lab tests revealed the counterfeit version contained sibutramine and not orlistat. Since then, FDA lab tests on the counterfeit product show that people may be taking three times the usual daily does (twice the recommended maximum dose ) of sibutramine if they are following the dosing directions for Alli. Side effects from excessive sibutramine include elevated blood pressure, stroke and heart attack if you have a history of heart disease; and anxiety, nausea, heart palpitations, racing heart, insomnia and small increases in blood pressure if you are healthy.
If you have been taking the counterfeit product, stop taking the drug and throw it away; contact your health provider if you are experiencing more than mild symptoms, especially if you have a history of cardiovascular disease; and call FDA's Office of Criminal Investigations at 800-551-3989 or by visiting the OCI Web site

Melina Kibbe honored at White House

Melina Kibbe honored at White House

Melina Kibbe, M.D., associate professor at Northwestern's Feinberg School of Medicine, vascular surgeon at Northwestern Memorial Hospital and co-chief of the vascular surgery service and director of the Vascular Laboratory at the Jesse Brown VA Medical Center recently received the Presidential Early Career Award for Scientists and Engineers (PECASE) at the White House.   This is the highest honor given by the U.S. government to outstanding scientists and engineers who are in the early stages of their research careers.

Her current research portfolio was primed, in part, by two Pioneer Awards the Institute for Women's Health Research (IWHR) awarded Dr. Kibbe and her postdoctoral fellow in 2008 and 2009, respectively.  Her research focuses on preventing vascular injury and scarring in blood vessels following stent surgery.   It wasn't until Dr. Kibbe  ran into Dr. Teresa Woodruff,  IWHR Director, a few years ago, who asked Kibbe if she was including female animals in her research, that she gave it much consideration. After that meeting, Kibbe searched publications in her field that included sex as a variable and she found there was very little.   With her Pioneer Awards, she proposed to include male and female animal models to study the benefits of nitric oxide (NO)-based therapies following stent surgery and found that the effect was totally different between the sexes!

The Pioneer Awards were developed by the IWHR to encourage researchers to include sex and gender analyses in their studies, and the work done in the Kibbe lab demonstrates how a small amount of funding targeted to sex-based research can produce startling results and change a whole field of study.   The immeasurable aspect of the PECASE award that Dr. Kibbe received is the invaluable  publicity it will give her research.  This may help focus on the importance of including sex variables in future vascular research and open doors to new collaborations and larger funding.

We probably all have first hand knowledge of how a bad night's sleep can affect us the next day: we're irritable, in a bad mood, and it can be hard to concentrate. It may not be all that surprising then, that how we sleep can be a very big part of depressive disorders, an incredibly interesting topic covered by Dr. Roseanne Armitage in the most recent installment of the IWHR's Women's Health Research Monthly Forum.

Dr. Roseanne Armitage

Dr. Roseanne Armitage

Dr. Armitage began her talk by discussing how men and women, even those who do not have depression, sleep in very different ways. Possibly because of the different numbers of hormone receptors  or the over 650 genes that are expressed differently in the brains of males and females, the types of sleep we have also differs. For example, before puberty, boys have more slow wave sleep (stage 3 and 4 sleep, the deep, restorative kind that makes you feel refreshed in the morning) than girls do. After puberty, this changes, and girls are the lucky receivers of more slow wave sleep. Most interestingly, while men have a very slow loss of the amount of slow wave sleep over their lifetimes, women's amount stays relatively level and then drops precipitously during the peri-menopausal years. This is one reason why menopausal women really notice the sudden change in their sleep patterns. In general, women are also more likely to suffer from insomnia and sleep fragmentation than men.

The depression that Dr. Armitage really focused on was untreated MDD (major depressive disorder). MDD is twice as likely to occur in women than in men. Social withdrawal and feelings of worthlessness and guilt are more common in females with depression than in males with depression, who tend to complain more of lack of goal-oriented behavior. Around 80% of people with MDD report sleep problems, and for many people, sleep disturbance is the first presenting symptom of MDD. In adults with MDD, there are increased arousals and episodes of wakefulness, increased stage 1 sleep (the very light sleep), decreased total sleep time, and decreased stage 3 and 4 sleep.

Depression further exacerbates the sex differences in sleep between men and women when faced with a serious change to their normal sleep patterns (such as being asked to stay up for 40 hours consecutively), women with MDD overresponded, staying in slow wave sleep for too long, while men with MDD underresponded.  Sleep in healthy adults also shows a high level of coherence, or a very close association in the activity patterns of the right and left hemispheres of the brain. Women with MDD, however, have a lower coherence during their sleep than other healthy females, healthy males, AND males with MDD.

Dr. Armitage's work also demonstrates the ability to tie sleep disturbances to the likelihood of depression in very young girls. She finds that coherence scores can be a very good predictor of future depressive disorder; girls who were at high-risk for depression because their mothers were depressed demontrate lower coherence in their sleep...even before they have any sign or symptom of depression. Young girls in this high-risk group also had very disorganized sleep-activity patterns, even as disorganized as same aged girls who already suffered from depression. Shockingly, even babies (2 to 30 weeks) of depressed mothers take longer to fall asleep, have decreased total sleep time and sleep efficiency, and spend less time in bright light (known to produce necessary vitamins) than babies of non-depressed mothers.

Our thanks to Dr. Roseanne Armitage for such an eye-opening talk! We encourage you to look at some of Dr. Armitage's published work on the topic:

I know what you’re thinking, this is a Women’s Health Blog - but we like men here too.  A recent study published in Nature (and featured in the New York Times) reveals some interesting new insight into the X-chromosome’s somewhat puny-looking counterpart.  Researchers Jennifer Hughes and David Page at the Whitehead Institute have discovered that the Y-chromosome appears to be evolving much faster than the rest of the genome.

Humans have 23 pairs of chromosomes (46 total); two of those chromosomes, called the sex chromosomes, are responsible for determining the sex of a human. Women have two of the same chromosomes, named X (see “What’s with the dancing X chromosomes?"), while men have one X chromosome and one Y chromosome, thus resulting in a mismatched pair.  Scientists have known for quite some time that the Y chromosome originally contained the same genes as the X chromosome, but has lost most of those genes through evolution.  Because of this, scientists have believed that the Y chromosome has been degrading through gene loss and has reached, or will reach a static state.

This new research however may prove otherwise.  In their study, Drs. Page and Hughes compared the genetic makeup of the human and the chimp.  Since chimps and humans shared a common ancestor just six million years ago, the differences in the genomes can help determine rates of evolution in the species.  The researchers found that while the chimp and human genomes differed in less than 1 percent of their DNA, comparison of the Y-chromosomes shows a difference of 30%.  This data indicates that this chromosome in particular is not static, but is in fact evolving at a greater rate than the rest of the genome.

The researchers suggest that some of this rapid evolutionary diversity might be attributable to differences in the mating patterns of humans and chimps and the large role of genes on the Y chromosome in sperm production.  A unique feature of the Y chromosome is that because it occurs in a mismatched pair with the X chromosome, it cannot exchange genes (called crossing-over) prior to meiotic cell division the way that the other twenty-two chromosomes do.   This places increased selective pressure on the Y chromosome, since a change in one gene must affect the reproductive fitness of the others.  In addition, the structure of the Y chromosome provides it with the opportunity to exchange genes with itself, which could accelerate the rate of change in its genetic sequence.

So does this mean that men are evolving faster than women?  No it doesn’t (sorry guys).  However, according to Andrew Clark, a geneticist at Cornell University (see NYT article), the rapid changes of the Y chromosome could have broader effects on the rest of the human genome.  Only further research will tell…

We welcome the new commentary from the Dean of the Feinberg School of Medicine here at Northwestern University entitled, "Diversity: Essential For Our Success." In it, Dr. Larry Jameson tells of his own personal history of growing up in the age where integration and diversity were just beginning to take hold as ideals of value. He discusses remembering very few women or people of racial minorities in his own medical class, and praises the efforts that have been taken to change this sad statistic in the school admissions, faculty hires, and work opportunities in the years since his school days. Dr. Jameson offers a few new insights, including his own hesitancy to think of race as any true separator;  a consequence of his knowledge regarding genetic similarities between all racial groups. Additionally, Dr Jameson offers this anecdote:

"We were asked (coerced) to take a Meyers-Briggs personality test. Based on the results, we were sorted into small groups with similar or differing profiles. All groups were given the same problem to solve. When we reported out, it was very clear that the more diverse groups had been more open-minded and creative, and had constructively addressed issues that required compromise. In contrast, the more homogeneous groups immediately focused on traditional solutions, were recalcitrant to compromise, and in some cases became too bogged down in old issues to even promote solutions. I generally dislike these kinds of exercises, but I learned that diversity yields better solutions."

That principle is one of the many reasons that the IWHR promotes diversity in the clinic and in the lab, as well as in the patient or study participant pool. We believe that a diverse population within the set of doctors and scientists who direct modern medicine will naturally lead to a greater insight and sensitivity to the needs of the diverse set of patients who benefit from new innovations and treatments.
