Article Synopsis
  • * Researchers analyzed data from 503 midlife women, focusing on various HDL components and their changes over time to see their impact on cognitive functions like working memory and processing speed.
  • * Findings suggest that higher levels of certain HDL metrics are linked to better memory and cognitive performance, indicating that improving these HDL measures could be beneficial for cognitive health, especially in relation to Alzheimer’s disease.

Patients treated for hypothyroidism with levothyroxine (LT4) monotherapy may present with persistent hypothyroidism symptoms, including cognitive symptoms, despite having a normal thyroid stimulating hormone (TSH) level. It remains unclear whether LT4 monotherapy is sufficient to normalize cognitive function outcomes over time. This is a multisite longitudinal study of a diverse group of women during midlife representing 5 ethnic/racial groups from 7 enrollment sites across the United States in the Study of Women's Health Across the Nation.

Article Synopsis
  • The study investigates the role of high-density lipoprotein cholesterol (HDL-C) in midlife women diagnosed with metabolic syndrome (MetS) and its relation to the risk of diabetes and carotid intima-media thickness (cIMT).
  • Researchers categorized participants into three groups: women without MetS, those with MetS and HDL-C levels ≥ 50 mg/dL (MetS hiHDL), and those with HDL-C < 50 mg/dL (MetS loHDL), measuring cIMT 13.8 years later and assessing diabetes risk yearly.
  • Findings indicate that although both MetS groups (hiHDL and loHDL) had higher risks of

Background: Cognitive decline may progress for decades before dementia onset. Better cardiovascular health (CVH) has been related to less cognitive decline, but it is unclear whether this begins early, for all racial subgroups, and all domains of cognitive function. The purpose of this study was to determine the impact of CVH on decline in the 2 domains of cognition that decline first in White and Black women at midlife.

Objective: Perimenopausal women experience a steep increase in low-density lipoprotein cholesterol (LDL-C) that is related to a higher risk of carotid plaque later in life. Low-density lipoprotein subclasses have been linked to cardiovascular diseases beyond LDL-C, promising a better risk stratification. We aim to characterize changes in LDL subclasses and assess their associations with presence of coronary artery calcium (CAC score ≥10) and carotid intima-media thickness (cIMT) over the menopausal transition (MT) and by menopause stage.

Background: The menopause transition (MT) is linked to adverse changes in lipids/lipoproteins. However, the related contributions of anti-Müllerian hormone (AMH) and estradiol (E2) are not clear.

Objective: To evaluate the independent associations of premenopausal AMH and E2 levels and their changes with lipids/lipoproteins levels [total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), apolipoprotein B (apoB) and apolipoprotein A-1 (apoA-1)] over the MT.

Objective: We hypothesized that, among midlife women with vasomotor and/or genitourinary symptoms of menopause, (1) hormone therapy (HT) compared with complementary alternative medicine (CAM) will be associated with higher quality of life (QoL), and (2) race/ethnicity would modify associations of HT and CAM with QoL.

Methods: Cross-sectional and longitudinal analyses of QoL in the Study of Women's Health Across the Nation participants using HT, CAM, or both. Women ( n = 2,514) completed a CAM use questionnaire and QoL assessments at baseline and every 1 to 2 years from 2002 to 2013.

Objective: During midlife, women experience changes in lipoprotein profiles and deterioration in vascular health measures. We analyzed the associations of groups of lipoprotein subfractions as determined by principal component analysis (PCA) with subclinical vascular health measures in midlife women and tested if these associations were modified by menopause status.

Methods: PCA was used to generate principal components (PCs) from 12 lipoprotein subfractions quantified among 545 midlife women.

Background Prevention of cardiovascular disease (CVD) is a public health priority. The combination of physical activity, a healthy diet, and abstaining from tobacco plays an important role in prevention whereas aspects of psychosocial well-being have largely been examined separately with conflicting results. This study evaluated whether the combination of indices of psychosocial well-being was associated with less progression of coronary artery calcium (CAC).
