ABSTRACT
Menopause is associated with the onset of climacteric symptoms due to low estradiol levels, which may cause insufficient maturation of the vaginal mucosa. Vitamin D may regulate the growth and differentiation of cells that are adversely affected due to low estradiol levels, thereby restoring vaginal health. The objective of this systematic review, the first on this subject, was to investigate the effect of vitamin D on the vaginal health of menopausal women. PubMed, Embase, Scopus, Web of Science, and Google Scholar databases and reference lists of hand-searched articles were searched for published studies from February 2000 to November 2018. The selection criteria were as follows: randomized or quasi-randomized trials that compared the effects of vitamin D or related compounds, alone or with calcium, on vaginal health (growth and differentiation of epithelial cells, dryness, acidity [pH]) outcomes in menopausal women. The methodological quality of these studies was examined using the Cochrane tool checklist by two independent investigators, following which the data were extracted. Of six examined studies, two showed that vitamin D administration improved the growth and differentiation of vaginal epithelial cells, improved vaginal pH, and decreased vaginal dryness in menopausal women. Although the level of evidence for the effects of vitamin D on vaginal health is low in our study, we concluded that vitamin D may improve the vaginal health of women, especially during menopause.

OBJECTIVES: Some conventional medications used to treat insomnia, such as benzodiazepine, non-benzodiazepine, and hormone therapy, are associated with side effects. Therefore, there is a growing interest in the use of herbal medicine. The aim of this systematic review is to assess the effects herbal medicines have on sleep disorders of peri- and postmenopausal women. METHODS: Three databases were searched including MEDLINE, Scopus, and the Cochrane Library from inception to March 2018. RESULTS: Six trials assessed the effect of soy on sleep disorders. Forrest plot for 2 studies showed that the standardized mean difference (SMD) of the sleep problems was lower in the soy group than the placebo group (SMD = −0.996; P < 0.001; 95% confidence interval, −1.42 to −0.563). Three trials showed soy had no significant effect on sleep disorders and one study showed a positive effect on sleep disorders. Accordingly, it is difficult to reach a definite conclusion regarding the effects of soy on sleep disorders based on these findings. According to a trial, significant beneficial effect associated with taking Schisandra chinensis. Findings suggested that some herbal medicines like red clover, lavender combined with bitter orange and pin bark extract had attenuating effects on sleep disorders. After intake of 530 mg of valerian twice a day for one month, statistically significant effects were observed regarding the quality of sleep of postmenopausal women. CONCLUSIONS: The present systematic review and meta-analysis found inadequate evidence to draw conclusions regarding the effectiveness of herbal medications, especially soy.
