A new study from the Women's Health Initiative (WHI) shows no significant connection between vitamin D levels and menopause symptoms. The study was published online today in Menopause, the journal of The North American Menopause Society.
The authors analyzed the relationship between the blood levels of vitamin D and a number of menopause symptoms, including hot flashes, night sweats, sleep disturbance, concentration, and forgetfulness in 530 women who participated in the calcium and vitamin D WHI trial.
There was good reason to look for a link because other studies have implied some relationship. For example, breast cancer patients with higher vitamin D levels have fewer hot flashes and other symptoms than women with lower levels. Supplementing vitamin D can improve mood in other groups of people. The vitamin can protect against depletion of serotonin, which plays a role in regulating body heat. And vitamin D deficiency can result in muscle and joint pain.
Furthermore, estrogen plays a role in activating vitamin D, meaning that the estrogen deficiency that comes with menopause could worsen any problems with vitamin D deficiency.
The number of symptoms and vitamin D levels had a borderline significant relationship at first, but after the analysts adjusted for multiple comparisons, the association disappeared. And in looking at multiple comparisons, no individual menopause symptoms were significantly associated with vitamin D either.
"With so many women taking vitamin D supplements these days, it is good to know what it can and cannot do. We need to be realistic in our expectations," says NAMS Executive Director Margery Gass, MD.
The authors cautioned that this study doesn't entirely prove that vitamin D levels and menopause symptoms are not connected because the sample of women they had with enough data was relatively small and the women, who averaged age 66, were nearly 16 years from menopause, and only 27 percent of the women in this group had hot flashes or night sweats. Looking at vitamin D levels in women as they go through the menopause transition might be valuable.
The article "Vitamin D levels and menopause-related symptoms" will be published in the November 2014 print edition of Menopause.
Founded in 1989, The North American Menopause Society (NAMS) is North America's leading nonprofit organization dedicated to promoting the health and quality of life of all women during midlife and beyond through an understanding of menopause and healthy aging. Its multidisciplinary membership of 2,000 leaders in the field—including clinical and basic science experts from medicine, nursing, sociology, psychology, nutrition, anthropology, epidemiology, pharmacy, and education—makes NAMS uniquely qualified to serve as the definitive resource for health professionals and the public for accurate, unbiased information about menopause and healthy aging.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
