METHODS: A total of 1875 community-dwelling climacteric women were included in this study. The Pittsburgh Sleep Quality Index (PSQI) and the Menopause Rating Scale (MRS) were adopted to assess sleep quality and menopausal symptoms, respectively. Data were collected 4 times from March 2019 to December 2019, at a 3-month interval.
RESULTS: The Cross-lagged analysis showed that worse sleep quality and more severe menopausal symptoms over time after controlling for specified covariates, and more severe menopausal symptoms were predicted by declined sleep quality. The Generalized estimation equation model showed that education level, marital status, chronic diseases, life events, income, and age were the influential factors of sleep quality, while menopausal symptoms were impacted by marital status and income.
CONCLUSIONS: Increasing negative sleep quality and more severe menopausal symptoms over time contribute to the health burden of climacteric women. Menopausal symptoms could be alleviated by sleep quality improvement, which is influenced by education level, marital status, chronic diseases, life events, age, and economic factors.
METHODS: A self-administrated, internet-based questionnaire was distributed in eight languages, through professional bodies to eye care practitioners globally. The questions examined: awareness of increasing myopia prevalence, perceived efficacy of available strategies and adoption levels of such strategies, and reasons for not adopting specific strategies.
RESULTS: Of the 1336 respondents, concern was highest (9.0 ± 1.6; p
METHODS: Male Sprague-Dawley (SD) rats were randomly divided into control group (CON), chronic unpredictable mild stress (CUMS) group, CUMS + electroacupuncture group (EA), and CUMS + fluoxetine group (FLX) (n = 10/group). Rats were given a 28-day treatment at the Shangxing (GV23) and Fengfu (GV16) acupoints with electroacupuncture or fluoxetine (2.1 mg/kg).
RESULTS: Rats exposed to CUMS induced depression-like behaviors and spatial learning-memory impairment, changed the ionized calcium binding adaptor molecule 1 (IBA-1), Vglut1, myelin basic protein (MBP), and postsynaptic density protein 95 (PSD95) level of hippocampal, increased the Nod-like receptor protein 3 (NLRP3), atypical squamous cell (ASC), Caspase level and hippocampal reactive oxygen species (ROS), and prompted the activation of Epha4-mediated signaling and an inflammatory response. Conversely, electroacupuncture administration reduced these changes and prevented depression-like behaviors and cognitive impairment. Electroacupuncture also promoted hippocampal expression of Sirtuin1(SIRT1), Nuclear factor erythroid 2-like (Nrf2), Heme oxygenase-1 (HO-1); reduced the expression of interleukin-1β (IL-1β), interleukin-18 (IL-18), and tumor necrosis factor-alpha (TNF-α); and prevented neural damage, particularly the synaptic myelin sheath, and neuroinflammation by regulating Eph receptor A4 (EphA4) in the hippocampal.
CONCLUSION: These results indicate that electroacupuncture prevents depression-like behaviors with cognitive impairment and synaptic and neuronal damage, probably by reducing EphA4, which mediates ROS hyperfunction and the inflammatory response.
