When Mirena Meets Mommybloggers

February 9th, 2010 by Elizabeth Kissling

Guest Post from Evil Slutopia

There are Tupperware parties, Passion Parties, Pampered Chef parties, and…Mirena IUD parties? Yes, apparently these events popped up early last year and were a joint effort from Bayer Pharmaceuticals and the mom marketing site Mom Central.

Here’s one mom blogger’s description of the Mirena party that she hosted:

Then tonight I hosted a party at my house with Mom Central. Mom Central had found me through this blog and asked me if I would be interested in hosting an event sponsored by Mirena. As I welcome any opportunity to sit down with some girlfriends with some free food and drink, I was happy to accept. Before the party started, I walked around nervously, terrified that only a couple of people would show up. We’re all so busy, and I worried that people would end up skipping a strange commercial-sounding event. But one by one, they rolled in and I began to relax.

We had an amazing evening, talking about sex, fashion, and living a simpler life. I realized that we don’t actually spend a lot of time talking about sex and relationships. We laughed a lot but also went home with some great tips.

Another Risk Associated with Hormone Therapy

February 7th, 2010 by Elizabeth Kissling

A study to be published in the British Medical Journal’s Thorax,* which focuses on respiratory medicine, finds that estrogen-only hormone treatment for menopause symptoms is associated with higher risk of asthma. The study involved nearly 58,000 women over 12 years. The researchers compared women who had never used any form of hormone treatment, women who used estrogen plus progestin, and women who used estrogen only treatment.Cartoon drawing of human lungs

The women who had used hormone treatments were 21% more likely to develop asthma; those who had used estrogen-only treatments showed a 54% higher overall risk of asthma.

Asthma is generally more common in young women after menarche, and more severe in women than in men.

*Neither the study nor the abstract appear to be available online.

Best pain relievers for cramps

January 20th, 2010 by Elizabeth Kissling

A new meta-analysis of previous research on acetaminophen (also known as paracetamol outside the U.S.) vs. NSAIDs (nonsteroidal anti-inflammatory drugs) for treatment of menstrual pain indicates that NSAIDs are more effective. NSAIDs include aspirin, ibuprofen, and naproxen sodium, which are all readily available over-the-counter in the U.S. The research pooled results from 73 randomized controlled trials comparing the effectiveness and safety of NSAIDs vs. placebo, vs. acetaminophen, and each other.

The results don’t indicate whether one NSAID is any better than any other for menstrual pain. Researcher Jane Marjoribanks, M.D., Cochrane Menstrual Disorders and Subfertility Group in Auckland, New Zealand, says they work by reducing prostaglandins, the substance manufactured by the uterine lining to help the uterus contract and expel menstrual fluid.

“Research has shown that women with dysmenorrhoea have high levels of prostaglandins, hormones known to cause cramping abdominal pain. …NSAIDs are drugs which act by blocking prostaglandin production.”

The study was published today in the Cochrane Database of Systematic Reviews.

‘Should You Get Rid of Your Period’ Debated at MSN

January 8th, 2010 by Elizabeth Kissling

SMCR and re:Cycling’s own Chris Hitchcock is featured in a menstrual suppression for-and-against article at MSN today. Chris explains why using hormonal contraceptives to stop periods is generally bad idea, except in very limited medical circumstances. Leslie Miller, professor of obstetrics and gynecology at University of Washington, defends the proposition that there’s no reason to menstruate unless one wants to get pregnant.

The article also includes a Consumer Reports video analysis of that annoying Seasonique ad that presents women as split personalities between “emotional” and “logical”. (Because it’s logical to get rid of menstruation – it only makes you emotional, dontcha know.)

Contraceptive Injections Increase Risk of Bone Loss

December 27th, 2009 by Elizabeth Kissling

DEXA scan of femur.New research from the University of Texas Medical Branch at Galveston finds that nearly half of women using depot medroxyprogesterone acetate (DMPA), commonly known as the birth control shot, will experience high bone mineral density (BMD) loss in the hip or lower spine within two years of beginning the contraceptive. Women who smoke, have inadequate calcium intake, and have never given birth are at higher risk of BMD loss.

The study, published in the January 2010 issue of Obstetrics and Gynecology, followed 95 DMPA users for two years. In that time, 45 women had at least five percent BMD loss in the lower back or hip. A total of 50 women had less than five percent bone loss at both sites during the same period. The researchers followed 27 of the women for an additional year and found that those who experienced significant BMD loss in the first two years continued to lose bone mass.

“These losses, especially among women using DMPA for many years, are likely to take an extended period of time to reverse,” says first author Dr. Mahburbur Rahman, assistant professor in the department of obstetrics and gynecology and Center for Interdisciplinary Research in Women’s Health.

The researchers note that while this study will help physicians counsel women with modifiable risk factors who wish to use DMPA, prevention of bone loss while using the contraceptive and reversibility of BMD loss are still not well understood and further research is needed.

DMPA, an injected contraceptive given every three months, is used by more than two million women in the U.S.; nearly one-quarter of them teens. DMPA is popular with young women because it is less expensive than many other forms of birth control, has a low failure rate, and does not require daily use.

Who Lacks Health Literacy?

December 18th, 2009 by Elizabeth Kissling

You may have heard the news that 23 hormone replacement therapy lawsuits filed by women diagnosed with breast cancer were dismissed by a New York judge this week. Judge Martin Shulman granted Pfizer’s motion to dismiss for two reasons: the plaintiff’s delayed filing exceeded the the three-year statute of limitations in New York, and that “the potential risk of contracting breast cancer from taking HRT medication was well known at all times out there in the stream of public information.” Oddly, Judge Shulman simultaneously asserted “that the debate over HRT health problems has not yet been settled.”

I can’t argue about exceeding the statute of limitations, but it’s difficult for a judge to assert that breast cancer risk of hormone therapy is well known public information. The Lancet reported today that up to half of US adults have trouble interpreting medical information, displaying low levels of health literacy. Health literacy, according to The Lancet, is the ability to comprehend and use medical information that can affect access to and use of the health-care system. Health literacy is more than reading and comprehending news reports of medical issues (which are often of poor quality – see Health News Review for sharp analysis of health news); one must also know how to navigate the complexities of the health care system, including knowing how and when to question one’s physicians and pharmacists.

Marketing Menopause

December 13th, 2009 by Elizabeth Kissling

popupThere’s a pretty good essay in this weekend’s New York Times (online here Saturday, in print Sunday in the Business section) about how hard Big Pharma has worked to market menopause as an estrogen deficiency disease. In addition to discussion of Wyeth’s advertising campaigns, the article mentions the firm’s contract with DesignWrite, a company drug makers pay to develop manuscripts for publication in medical journals, to prepare at least 60 articles for publication in medical journals on the potential benefits of hormone therapy for cardiovascular disease, Alzheimer’s disease, diabetes, colon cancer, vision loss and other health problems.

The article also includes access to PDFs of some of the thousands of pages of documents from Wyeth that were requested by plaintiffs in the lawsuits against the drug manufacturer. (To date, more than 13,000 people have sued Wyeth claiming that they developed breast cancer and other health problems after taking the company’s menopausal hormone drugs. As we reported three weeks ago, in ten of the twelve verdicts so far, juries have awarded significant sums to plaintiffs. ) The documents available at the New York Times include a publication plan for Wyeth from DesignWrite, a 1995 product launch speech from Wyeth’s marketing director proclaiming the company’s mission of bringing to fruition Dr. Bernadine Healy’s vision of “a world in which the vast majority of women would begin taking HRT, and we know that means Prempro, at menopause and continue on for the rest of their lives.” There’s also this handwritten note from a 1996 meeting about how to respond to a new study raising breast cancer concerns (red markings added by me):

Women’s Health News: Cancer Genes, HPV Vaccine

December 11th, 2009 by Elizabeth Kissling

gardasilToday I want to point to two important articles about women’s health from our friends at Women’s eNews:

  1. Yesterday, they published a story about Myriad Genetics and their firm grasp on the patents for diagnostics tests for BRCA1 and BRCA2 genes, which are known to place women at high risk for breast and ovarian cancers. Until the patents expire in 2014 and 2015, its laboratory is the only place in the country where diagnostic testing for the BRCA genes can be performed. A lawsuit representing patients, women’s health groups, medical professionals and four organizations has been filed bythe American Civil Liberties Union, or ACLU, and the Public Patent Foundation.
  2. Today, Women’s eNews published a story about the need for more research on Gardasil, the HPV vaccine recommended for young women and recently approved for boys and young men too.

Early menarche, late menopause and breast cancer – what’s the whole story?

Can having too many menstrual cycles give you breast cancer?  That’s what one might conclude from two unrelated articles that appeared in national newspapers this week.

First was Nicholas D. Kristof’s Op-Ed in the New York Times. Kristof had recently attended a symposium exploring whether certain common chemicals are linked to breast cancer and other ailments. The role of estrogen – both the real thing our bodies produce and the pseudo-estrogens – in breast cancer was his major example.

The real thing:

One theory starts with the well-known fact that women with more lifetime menstrual cycles are at greater risk for breast cancer, because they’re exposed to more estrogen. For example, a woman who began menstruating before 12 has a 30 percent greater risk of breast cancer than one who began at 15 or later.

The pseudo-estrogens:

One class of chemicals that creates concern — although the evidence is not definitive — is endocrine disruptors, which are often similar to estrogen and may fool the body into setting off hormonal changes. This used to be a fringe theory, but it is now being treated with great seriousness by the Endocrine Society the professional association of hormone specialists in the United States. …These endocrine disruptors are found in everything from certain plastics to various cosmetics.

Taking Women’s Health Seriously

December 8th, 2009 by Elizabeth Kissling

Here’s one way that Canada shows some concern for risks to women’s health: the owner of a New Brunswick health food store was fined $7500 for smuggling a progesterone-laced cream from the U.S. The cream, called Aim Renewed Balance, is purported “to help restore balance between the hormones that cause premenstrual syndrome and menopause symptoms, such as hot flashes and mood swings.” It is not approved for use in Canada.

A Pain Reliever for Every Symptom

December 1st, 2009 by Elizabeth Kissling

Excedrin-1A friend just pointed me to Excedrin’s web page for Excedrin® Menstrual Complete, with “a unique triple ingredient combination that relieves 5 of your major symptoms — bloating, cramps, muscle aches, headache, and fatigue.” You know, for “[w]hen your period feels like it’s going to be one of those days.”

Friends, it’s not really a unique combination, since it’s EXACTLY the same ingredient blend contained in plain ol’ Excedrin® Extra Strength and in Excedrin® Migraine:

excedrin_ingredients
Well, there is one difference. Caffeine is identified as a “pain reliever aid” in the other two formulas, while in Excedrin® Menstrual Complete it’s called a diuretic.

I’m not saying that acetaminophen, aspirin, and caffeine won’t cure what ails you, just telling Novartis they’re not fooling anybody with this gambit.

New Drug for Heavy Periods

November 14th, 2009 by Elizabeth Kissling

The FDA announced yesterday that they have approved tranexamic acid tablets for the treatment of heavy menstrual bleeding, under the brand name Lysteda. According to the press release, approximately 3 million US women experience heavy bleeding, usually with no underlying health condition. The report states that there was  a statistically significant reduction in menstrual blood loss in women who received Lysteda, compared with those taking placebo.

As is the case with many newly approved drugs, tranexamic acid is not a new drug but an approval for a new usage: tranexamic acid has been used in injection form more than 20 years to reduce bleeding during tooth extraction in people with hemophilia (a blood disorder in which blood lacks a clotting factor).

Although it’s unlikely that anyone using hormonal contraceptives would also have heavy menstrual bleeding (remember, hormonal contraceptives suppress menstruation), the new drug comes with a big warning: taking Lysteda along with hormonal contraceptives increases one’s risk of blood clots, stroke, or heart attack.

I’m not a biochemist or a physician, but it sounds like Lysteda is a viable alternative for women who are currently taking (or recommended to take) hormonal contraceptives for the management of menstrual bleeding.
