New progestogen-only treatment effective in stopping acute abnormal uterine bleeding

New research from the Los Angeles Biomedical Research Institute (LA BioMed) found a progestogen-only treatment halted bleeding in women suffering from extremely heavy periods, according to the study published online by the American Journal of Obstetrics and Gynecology.

Tips for menopausal women to better enjoy their sex lives

Menopause can be a real rollercoaster—and that can impact women's sex lives. It can cause women's libidos to climb, suddenly drop, and then climb again due to the combination of estrogen and women's own levels of testosterone powering this wild cycle.

Menopausal brain changes support estrogen’s protective role in schizophrenia

Researchers have found morphological differences between pre- and postmenopausal women with schizophrenia that support a protective role for estrogen in the psychiatric disorder.

MicroRNA can be used to define four subtypes of triple-negative breast cancer

A new, large-scale study of triple-negative breast cancer shows that small molecules called microRNA can be used to define four subtypes of this aggressive malignancy.

Long-acting reversible contraception with progestin may increase risk of type 2 diabetes in women

A first-of-its-kind study by researchers at the Keck School of Medicine of the University of Southern California (USC) indicates that healthy, obese, reproductive-age women who use long-acting reversible contraception (LARC) containing the hormone progestin have a slightly increased risk for developing type 2 diabetes when compared to those who use non-hormonal contraception.

Combination of two antibodies prevents growth and spread of triple-negative breast tumors

Cancer drugs of the new, molecular generation destroy malignant breast tumors in a targeted manner: They block characteristic molecules on tumor cells - receptors for the hormones estrogen or progesterone, or a co-receptor, called HER2, that binds to many growth factors. But about one in every six breast tumors has none of these receptors. Such cancers, called triple-negative, are particularly aggressive and notoriously difficult to treat.

MammaPrint breast cancer test can help women avoid chemotherapy

The MammaPrint breast cancer test can dramatically reduce the number of women who need to undergo chemotherapy to treat the disease, according to a newly published study.

Direct link between exposure to pesticides in food, air and water and prevalence of type 2 diabetes

A study led by the University of Granada reveals that there is a direct relationship between the presence of Persistent Organic Pollutants in the body and the development of type 2 diabetes, regardless of the patient's age, gender or body mass index.

Women with BRCA gene mutations tend to undergo menopause sooner than others

Women with harmful mutations in the BRCA gene, which put them at higher risk of developing breast and ovarian cancer, tend to undergo menopause significantly sooner than other women, allowing them an even briefer reproductive window and possibly a higher risk of infertility, according to a study led by researchers at UC San Francisco.

Study shows how GATA3 protein acts downstream biochemically to prevent breast cancer metastasis

The spread of breast cancer to distant organs within the body, an event that often leads to death, appears in many cases to involve the loss of a key protein, according to UC San Francisco researchers, whose new discoveries point to possible targets for therapy.

Findings could help explain prevalence of urinary tract infections in post-menopausal women

Researchers from Washington University School of Medicine, St. Louis, show that reservoirs of uropathogenic E. coli within the bladder exist in higher numbers post-menopause than pre-menopause in a mouse model, a finding that could help explain the greater prevalence of urinary tract infections in post-menopausal women.

Researchers find new genetic differences in human hearts

Healthy men and women show little difference in their hearts, except for small electrocardiographic disparities. But new genetic differences found by Washington University in St. Louis researchers in hearts with disease could ultimately lead to personalized treatment of various heart ailments.

Mice exposed to BPA exhibit spontaneous activity, have leaner body mass

Female mice exposed to Bisphenol A through their mother's diet during gestation and lactation were found to be hyperactive, exhibit spontaneous activity and had leaner body mass than those not exposed to the chemical, researchers at the University of Michigan School of Public Health have discovered.

Boosting estrogen levels may help reduce urinary infections in menopausal women

Estrogen levels drop dramatically in menopause, a time when the risk of urinary tract infections increases significantly.

Very low levels of BPS can disrupt natural estrogen hormone actions

A few years ago, manufacturers of water bottles, food containers, and baby products had a big problem. A key ingredient of the plastics they used to make their merchandise, an organic compound called bisphenol A, had been linked by scientists to diabetes, asthma and cancer and altered prostate and neurological development.

SLU team discovers molecular pathway that contributes to triple-negative breast cancer

In research published in the Jan. 17 issue of The Journal of Cell Biology, a team led by Susana Gonzalo, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University, has discovered a molecular pathway that contributes to triple-negative breast cancer, an often deadly and treatment resistant form of cancer that tends to strike younger women.

BRCA1-deficient cancer cells take advantage of DNA repair mechanism

Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing themselves from stagnation or death. The study appears in the January 21st issue of The Journal of Cell Biology.

Tamoxifen can counteract some pathologic features in mouse model of DMD

A new study has found that tamoxifen, a well-known breast cancer drug, can counteract some pathologic features in a mouse model of Duchenne muscular dystrophy (DMD). At present, no treatment is known to produce long-term improvement of the symptoms in boys with DMD, a debilitating muscular disorder that is characterized by progressive muscle wasting, respiratory and cardiac impairments, paralysis, and premature death.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

Mirena coil intrauterine device a better treatment for heavy menstrual periods

The hormone-releasing Mirena coil intrauterine device (IUD) is a better treatment for heavy menstrual periods than other conventional medical approaches, according to results of a major clinical trial led by scientists from the Universities of Nottingham and Birmingham.
