Calcium and vitamin D are commonly recommended for older women, but the usual supplements may actually send calcium excretion and blood levels too high for some women, shows a new study published online in Menopause, the journal of The North American Menopause Society (NAMS).
This randomized, placebo-controlled trial included 163 older (ages 57 to 90) white women whose vitamin D levels were too low. The women took calcium citrate tablets to meet their recommended intake of 1,200 mg/day, and they took various doses of vitamin D, ranging from 400 to 4,800 IU/day. The trial was limited by ethnicity because different ethnic groups metabolize calcium and vitamin D differently.

Today in Lab History: June 19, 1902- Barbara McClintock
Barbara McClintock was an American scientist, born June 19, 1902, regarded as one of the most important figures in the history of genetics. In the 1940s and 1950s McClintock’s work on the cytogenetics of maize led her to theorize that genes are transposable — they can move around — on and between chromosomes.

The Food and Drug Administration is warning women that a surgical procedure to remove noncancerous growths from the uterus could inadvertently spread cancer to other parts of the body.
The agency is discouraging doctors from performing the procedure, which uses an electronically powered device to grind and shred uterine tissue so it can be removed through a small incision in the abdomen. Known as laparoscopic power morcellation, the technique is widely used to treat painful fibroids, either by removing the growths themselves or the entire uterus.

Milk May Delay Osteoarthritis in Women
New research reports that women who frequently consume fat-free or low-fat milk may delay the progression of osteoarthritis (OA) of the knee. Results published in the American College of Rheumatology (ACR) journal, Arthritis Care & Research, published by Wiley, show that women who ate cheese saw an increase in knee OA progression. Yogurt did not impact OA progression in men or women.

Organic Food Doesn’t Lower Cancer Risk
Women who always or mostly eat organic foods have the same likelihood of developing cancer as women who eat conventionally produced foods, according to an Oxford Univ. study.
Kathryn Bradbury and colleagues in Oxford’s Cancer Epidemiology Unit found no evidence that regularly eating a diet that was grown free from pesticides reduced a woman’s overall risk of cancer.

University Works to Fix Wikipedia’s Female Scientists Deficit
Look up a female scientist or technologist on Wikipedia, and you might not find what you’re looking for. Many don’t have detailed pages or any page at all on the free online encyclopedia created by contributors, the vast majority of them men.
It’s a symptom of a larger problem for women in so-called STEM fields — science, technology, engineering and mathematics — where men far outnumber women. Even women who have done pioneering work in these fields don’t always get recognition. Since 2009, no woman has won a Nobel Prize in science.

Peanut Butter-Rich Childhood May Help Women Avoid Cancer
Here’s some news worth spreading: girls who eat more peanut butter could improve their breast health later in life. That’s according to a study from Washington Univ. School of Medicine in St. Louis and Harvard Medical School. The research shows that girls ages nine to 15 who regularly ate peanut butter or nuts were 39 percent less likely to develop benign breast disease by age 30.
Benign breast disease, although noncancerous, increases risk of breast cancer later in life. “These findings suggest that peanut butter could help reduce the risk of breast cancer in women,” says senior author Graham Colditz, associate director for cancer prevention and control at Siteman Cancer Center at Barnes-Jewish Hospital and Washington Univ. School of Medicine.

Meal Timing Can Improve Fertility in Women with PCOS
Polycystic Ovarian Syndrome (PCOS), a common disorder that impairs fertility by impacting menstruation, ovulation, hormones and more, is closely related to insulin levels. Women with the disorder are typically “insulin resistant” — their bodies produce an overabundance of insulin to deliver glucose from the blood into the muscles. The excess makes its way to the ovaries, where it stimulates the production of testosterone, thereby impairing fertility.
Now Daniela Jakubowicz of Tel Aviv Univ.’s Sackler Faculty of Medicine and the Diabetes Unit at Wolfson Medical Center has found a natural way to help women of normal weight who suffer from PCOS manage their glucose and insulin levels to improve overall fertility. And she says it’s all in the timing.

Vinegar Cancer Test Saves Lives
A simple vinegar test slashed cervical cancer death rates by one-third in a remarkable study of 150,000 women in the slums of India, where the disease is the top cancer killer of women.
Doctors reported the results at a cancer conference in Chicago. Experts called the outcome “amazing” and says this quick, cheap test could save tens of thousands of lives each year in developing countries by spotting early signs of cancer, allowing treatment before it’s too late.

Hormone Replacement is Safe
A new study has examined the cognitive effects of hormone therapy on memory, language and concentration in menopausal women.
A study, published in the Menopause journal, examined the effects of hormone replacement therapy (HRT) E2D, which used a combination of hormones estradiol and drospirenone to treat women. Early postmenopausal women aged between 49 and 55 who had never used HRT were assessed over a six-month period.
The treatment resulted in significant improvement in menopausal symptoms including hot flushes, night sweats and sexual function, and it lowered blood pressure and weight in comparison to those who were treated with an identical placebo.

Calcium, Vitamin D Pills Do Little to Help Healthy Women
Popping calcium and vitamin D pills in hopes of strong bones? Healthy older women shouldn’t bother with relatively low-dose dietary supplements, say new recommendations from a government advisory group.
Both nutrients are crucial for healthy bones and specialists advise getting as much as possible from a good diet. The body also makes vitamin D from sunshine. If an older person has a vitamin deficiency or bone-thinning osteoporosis, doctors often prescribe higher-than-normal doses.

Women appear to have a higher risk of implant failure than men following total hip replacement after considering patient-, surgery-, surgeon-, volume- and implant-specific risk factors, according to a report published by JAMA Internal Medicine, a JAMA Network publication.
Total hip replacement, also known as total hip arthroplasty (THA), is more often performed in women than men. Sex-specific risk factors and outcomes have been investigated in other major surgical procedures and, in theory, might be more important to study in THA because of anatomical differences between men and women, the authors write in the study background.

When a woman is postmenopausal and overweight, losing weight is a good thing, but gaining back just a few pounds may actually be detrimental to her cardiovascular health. New research from Wake Forest Baptist Medical Center found that gaining weight back after intentional weight loss is associated with negative long-term effects on some cardiometabolic (CM) risk factors in postmenopausal women.
In this paper, published online by the Journal of Gerontology: Medical Sciences, lead authors Daniel Beavers and Kristen Beavers wanted to look at how weight regain affects health risk in these women. The researchers looked specifically at CM risk factors – a cluster of risk factors that are indicators of a person’s overall risk for type 2 diabetes and cardiovascular disease. They include blood pressure, HDL and LDL cholesterol, triglycerides, fasting glucose and insulin.
