The correlation of the fecal microbiome with the biochemical profile during menopause: a Brazilian cohort study.

BACKGROUND: Hormonal, biochemical, and metabolic changes after menopause may alter the quality of life of women, leading to vasomotor, psychological, and genitourinary symptoms, and changes in their gut microbiota, which regulates estrogen levels through the estroboloma. Fecal samples were used to investigate the changes in the gut microbiota during aging and hormonal changes in women. A balanced gut microbiota has been associated with health or disease conditions and remains poorly understood after menopause. This study identified the fecal microbiota, and their association with biochemical and hormonal parameters of a cohort of women in the climacteric in the city of Ouro Preto-MG, Brazil. METHODS: A total of 102 women aged 40 to 65 years old were recruited and distributed into three groups according to the STRAW criteria for reproductive stage: reproductive (n = 18), premenopausal (n = 26), and postmenopausal (n = 58). Blood samples were collected to measure their serum biochemical and hormone levels, and the participants answered a questionnaire. The gut microbiota was analyzed from fecal samples by qPCR using the genera Bifidobacterium, Bacteroides, Lactobacillus, and Clostridium. RESULTS: The following parameters showed differences among the groups: total cholesterol, triglycerides, VLDL, ApoB, urea, calcium, uric acid, and alkaline phosphatase (p < 0.05). qPCR revealed the genus Clostridium to be the most abundant in all three groups. In the reproductive age group, the significant correlations were: Bacteroides with glucose (r = -0.573 p = 0.0129), and SDHEA (r = -0.583 p = 0.0111). For the premenopausal group, they were: Bifidobacteria with total cholesterol (r = 0.396 p = 0.0451), LDL (r = 0.393 p = 0.0468), ApoB (r = 0.411 p = 0.0368); Lactobacillus and calcium (r = 0.443 p = 0.0232), ALP (r = 0.543 p = 0.0041), LPa (r =-0.442 p = 0.02336); and Bacteroides and urea (r =-0.461 p = 0.0176). In the postmenopausal group, they were Bifidobacterium and ALP (r =-0.315 p = 0.0159), Lactobacillus and urea (r =-0.276 p = 0.0356), and Clostridium and beta estradiol (r =-0.355 p = 0.0062). CONCLUSION: In conclusion, the hormonal and metabolic changes during menopause in the population studied were accompanied by a significant change in the fecal microbiota, especially of the genus Clostridium.

Climacteric symptoms and quality of life in yoga practitioners.

BACKGROUND: Yoga is among the most commonly studied complementary therapies for managing climacteric symptoms. However, it is unclear whether yoga practices in premenopause can affect the occurrence of symptoms when women reach menopause. OBJECTIVE: To assess climacteric symptoms and quality of life in regular yoga practitioners and to determine whether yoga practices before menopause may avoid or mitigate climacteric-related symptoms. DESIGN: This study of 108 women between 40 and 65 years old included 28 women who started to practice yoga in premenopause and had already practiced for at least five years, and as controls 30 physical activity practitioners (PA) who had practiced for at least five years, and 50 sedentary women. MAIN OUTCOME MEASURES: Climacteric symptoms were evaluated with the Kupperman Menopausal Index (KMI) and the Women's Health Questionnaire (WHQ). Moreover, we measured the quality of life with the WHQ. RESULTS: The KMI showed that 39.3% of yoga practitioners had no menopausal symptoms, and none reported severe symptoms. The WHQ indicated a few symptoms and a good quality of life for yoga practitioners (3.56; 3.35-3.80). In addition, we found that the yoga group had significantly less moderate and severe symptoms (p = 0.002) compared with the sedentary group. We also observed that yoga practitioners had less vasomotor symptoms and memory/concentration disorders than PA practitioners (p = 0.010 and p = 0.047) and sedentary women (p = 0.001 and p = 0.001) and also used fewer drugs than the PA (p < 0.001) and the sedentary groups (p = 0.001). CONCLUSIONS: Yoga practitioners who started to practice in premenopause had satisfactory results on the frequency and intensity of climacteric symptoms and quality of life. Although further research is required to support our findings, we conclude that yoga practice may represent an efficient non-pharmacological approach to manage and prevent climacteric symptoms.
