Summary of the 2023 Thai Menopause Society Clinical Practice Guideline on Menopausal Hormone Therapy.

The Thai Menopause Society is an academic organization consisting of healthcare professionals engaged in menopause medicine. The position statement was first issued in 1994 and updated in 2003 and 2023. Herein, we reviewed the important updates of the 2023 position statement on menopausal hormone therapy (MHT) as an international reference for healthcare professionals in Thailand. An advisory panel of clinicians and research experts in the field of menopause reviewed the recommendation of published International Consensus Statements and updated the evidence using the MEDLINE database through PubMed. The evidence-based information and relevant publications were assessed, and a consensus on recommendations was subsequently achieved using the level of evidence to determine the recommendation strength and evidence quality. MHT remains the most effective treatment for vasomotor symptoms and genitourinary syndromes of menopause even after 20 years. Additionally, it is effective in preventing bone loss and fractures in postmenopausal women. The cardiovascular risk of MHT increased in women who initiated MHT after 60 years of age. Hormone therapy should be individualized following the hormone type, dose, administration route, use duration, and progestogen inclusion. The necessary pretreatment evaluation and appropriate follow-up recommendations were added for improved MHT standard care. The updated 2023 Clinical Practice Guideline on MHT is useful for gynecologists, general physicians, endocrinologists, and other healthcare professionals in treating menopausal women receiving hormone therapy in Thailand.

Prevalence of female pattern hair loss in postmenopausal women: a cross-sectional study.

OBJECTIVE: To identify the prevalence of female pattern hair loss (FPHL), hair characteristics, and associated factors in healthy postmenopausal women. METHODS: Two hundred postmenopausal women aged 50 to 65 years were recruited. Each participant was evaluated for FPHL according to Ludwig's classification using standardized global photography in all six views and trichoscopy for hair density and diameter. Three dermatologists re-evaluated all pictures for confirmation of FPHL. The time since menopause, levels of scalp sebum, serum testosterone, estradiol, thyroid stimulating hormone, and hemoglobin; family history of hair loss, as well as an evaluation of low self-esteem were evaluated. Women who underwent recent hair loss treatments were excluded. We used simple and multivariable logistic regression analysis to identify the factors affecting FPHL. RESULTS: In total, 178 postmenopausal women were evaluated for hair-loss patterns. The average age and time since menopause were 58.8±4.1 and 9.2 ± 5.6 years, respectively. The prevalence of FPHL was 52.2% (95% CI, 44.6-59.8). Severity of FPHL by Ludwig grades I, II, and III was 73.2% (95% CI, 62.9-81.8), 22.6% (95% CI, 14.6-32.4), and 4.3% (95% CI, 1.2-10.7), respectively. Logistic regression analysis revealed that age, time since menopause, and body mass index were all significantly associated with FPHL. After adjusting for age and family history of FPHL, only body mass index ≥25 kg/m2 was significantly associated with FPHL (adjusted OR = 2.65, 95% CI, 1.23-5.70). Conclusion: The prevalence of FPHL was high in postmenopausal women, raising the need for hair loss awareness in menopause clinics. Early detection and proper treatment of FPHL may increase the quality of life in postmenopausal women.

Alu hypomethylation in naturally and surgically postmenopausal women; a cross-sectional study.

Menopause, which may accelerate the hallmarks of the natural aging process, represents a point in time characterized by the permanent cessation of menstruation following the loss of ovarian estrogen production. Unlike natural menopause, which is characterized by a gradual decrease in estrogen production, when both ovaries are removed before the natural age of menopause, the onset of estrogen deprivation is abrupt. Further, a decrease in genome methylation frequently occurs in aging cells, and the major interspersed repetitive DNA elements in humans are Alu elements. In blood cells, Alu demethylation starts at an age of approximately 40 years, and increases with age. Here, we explored the Alu methylation levels corresponding to age-matched pre-menopausal, naturally postmenopausal, and surgically postmenopausal women aged 45-55 years (n = 60 in each group). Our results indicated that the body mass index (BMI), time-since-menopause, and Alu methylation levels corresponding to the three groups were significantly different. However, no correlations between Alu methylation level and BMI, time-since-menopause, or age were observed. Additionally, the Alu methylation level corresponding to the natural post-menopause group was significantly lower those corresponding to the pre-menopausal (p = 0.001) and surgical post-menopausal (p = 0.037) groups. In conclusion, Alu hypomethylation occurs in naturally postmenopausal women, implying that when women reach the age of natural menopause, the cell aging process may progress significantly with genome hypomethylation. These findings, notwithstanding, further studies are necessary to clarify whether bilateral oophorectomy before the age of menopause affects the cell aging process to a greater extent than natural menopause, and whether estrogen therapy or other interventions can delay cell aging in this regard.

Prevalence of pre-sarcopenia among postmenopausal women younger than 65 years.

OBJECTIVE: Sarcopenia is associated with high morbidity and mortality in older women. Early detection and intervention during the postmenopausal period were hypothesized to help maintain muscle mass and performance. Although the Asian Working Group has developed guidelines for sarcopenia management, the condition has not been sufficiently investigated in the middle-aged cohort of the Asian population. This study aimed to measure the prevalence of pre-sarcopenia and sarcopenia in middle-aged postmenopausal women and to determine the factors associated with low muscle mass. METHODS: In this cross-sectional study conducted in the Menopause Clinic, King Chulalongkorn Memorial Hospital, we used the bioelectrical impedance analysis method to determine the appendicular muscle mass using a body composition analyzer (TANITA MC980 Plus). Appendicular muscle mass index, handgrip strength, and 6-m gait speed were measured in 340 women aged 45 to 65 years. Hormonal profiles, anthropometric data, and relevant history were recorded. RESULTS: The mean age of the study participants and time since menopause were 57.8 ±â€Š4.5 years and 9.4 ±â€Š5.5 years, respectively. The proportion of pre-sarcopenic, sarcopenic, and nonsarcopenic women were 11.8%, 2.7%, and 85.6%, respectively. A body mass index ≤ 20 kg/m2 had the strongest correlation with low muscle mass (odds ratio 7.1; 95% confidence interval 3.0-16.8, P < 0.001). CONCLUSION: Nearly 12% of Thai middle-aged postmenopausal women were pre-sarcopenic. Early detection of symptoms of pre-sarcopenia and maintenance of a healthy body mass index may reduce the burden of this condition for middle-aged and older women.
