Article
Objective: Data: Fat mass has been shown to increase in aging women; however, the extent to which menopausal status mediates these changes remains unclear. The purpose of this review was to determine (1) how fat mass differs in quantity and distribution between premenopausal and postmenopausal women, (2) whether and how age and/or menopausal statu...
Article
Objectives: The aim of the study was to determine lipid profile differences between premenopausal and postmenopausal women. Methods: The present review used a meta-analytic approach. Sixty-six studies were included, which provided a total sample of 114,655 women consisting of 68,394 that were premenopausal and 46,261 that were postmenopausal. R...
Article
Objective This study aimed to investigate cross‐sectional and longitudinal associations between fat mass (i.e., body mass index [BMI], waist circumference [WC], and waist to hip ratio [WTHR]) and hippocampal volumes. Methods UK Biobank participants (N = 20,395) aged 40 to 70 years (mean follow‐up = 7.66 years), were included and categorized into o...
Article
Objectives: To investigate the cross-sectional association between measures of menstruation history (including menopausal status, age of menopause, age of menarche, and duration of reproductive stage) and brain volume. Methods: Women (aged 45 to 79 years) from the UK Biobank were included (n = 5,072) after excluding those who had (1) hysterectom...
Article
Our objective was to distinguish ALS, ALS-FTD and bvFTD via a novel visual MRI cortical atrophy scale that can be employed in a clinical setting. MRI images of 100 participants (33 ALS, 11 ALS-FTD, 22 bvFTD and 34 controls) were rated in four brain areas: orbitofrontal cortex, anterior temporal pole, anterior cingulate, and motor cortex. Areas were...

Introduction Sleep is an emerging risk factor for dementia but its association with brain health remains unclear. Methods A total of 29,545 UK Biobank participants with sleep measures and brain scans, and a subset (n=14,206) with cognitive measures were included. Multiple linear regression analyses were conducted to study the associations between s...

Menopause nomenclature varies in the scholarly literature making synthesis and interpretation of research findings difficult. Therefore, the present study aimed to review and discuss critical developments in menopause nomenclature; determine the level of heterogeneity amongst menopause definitions and compare them with the Stages of Reproductive Ag...
Thesis
Full-text available
Maintaining a healthy brain has been recognised as an important health challenge facing women, given global estimates indicate almost twice as many women die of dementia than men. In part, this is due to their increased longevity, however, this does not explain all of the difference. Other contributors include different exposure to risk factors as...
Article
First-year undergraduates may be particularly prone to experiencing difficulties with facilitating feelings of relatedness, due to the recent shift in educational environments (i.e. from high school to university), which may be unfamiliar. Therefore, the current study aimed to determine whether the implementation of a single pedagogical strategy, c...

The interest in, and use of, computers and software for assessment is reported to be increasingly popular via electronic examinations (e-exams). We deepen our understanding of the design, reception and effectiveness of e-exams for history and philosophy of science modules, undertaken by first-year advanced science and medical science students at un...

Macrophage inhibitory cytokine-1 (MIC-1), also known as growth differentiation factor 15 (GDF15), is a stress response cytokine. MIC-1/GDF15 is secreted into the cerebrospinal fluid and increased levels of MIC-1/GDF15 are associated with a variety of diseases including cognitive decline. Furthermore, Mic-1/Gdf15 knockout mice (Mic-1 KO) weigh more,...
