Background: Elevated high-sensitivity cardiac troponin (hs-cTn) levels are linked with cardiovascular disease and cognitive impairment, both of which are strong risk factors for late-life dementia (LLD). This study examined the association between hs-cTnI levels below the sex-specific 99th percentile for myocardial injury and the incidence of LLD in older women.
Methods: 986 community-dwelling women aged ≥70 years without prior LLD and with hs-cTnI <15.
Background: It is unknown if prevalent vertebral fracture (PVFx) captured on bone density vertebral fracture assessment (VFA) images predicts incident CVD events.
Methods: 11,760 individuals (mean [SD] age 75.7 [6.

Purpose: Survival after a cancer diagnosis is improving, increasing the importance of understanding and managing long-term treatment-related adverse effects. This study aimed to understand breast and prostate cancer survivors' understanding of how cancer treatment may affect cardiovascular and musculoskeletal health.
Methods: Australian breast and prostate cancer survivors treated with therapies with known cardiovascular adverse effects were recruited via a private cancer care provider.
Aims: Higher cruciferous vegetable (e.g., broccoli) intake is associated with lower risk of type 2 diabetes and cardiovascular disease, but limited causal evidence exists.
View Article and Find Full Text PDFBackground: Growing evidence suggests that health outcomes of dietary nitrate and nitrite intake are food source dependent. Robust evaluations in dietary studies necessitate a comprehensive and current food composition database of nitrate/nitrite content, along with variation based on country or region of origin, calendar year, growing season, and cooking method.
Objectives: The objectives of this study were to update the previous animal- and plant-based food nitrate/nitrite databases and investigate effects of cooking methods, seasonal and geographic variations, and longitudinal changes on nitrate and nitrite content to guide application of the database in observational and clinical studies.
Purpose: Vitamin K may inhibit vascular calcification, a common attribute of atherosclerotic vascular diseases (ASVDs). We examined associations between dietary vitamin K1 intakes and both subclinical atherosclerosis and ASVD events, including hospitalisations and mortality, in older women.
Methods: 1,436 community-dwelling women (mean ± SD age 75.
Purpose: Diabetes mellitus (DM) confers an increased risk of fracture. Fracture risk stratification techniques are imperfect, and preventative therapies are sparse. We aimed to describe features associated with a dysfunctional bone metabolism determined by F-Sodium Fluoride Positron Emission Tomography (F-NaF PET) in patients with DM and test the effects of vitamin K1 and colchicine therapy on vertebral F-NaF activity.

We aimed to determine whether SAD from DXA performed for osteoporosis assessment predicts major adverse cardiovascular events (MACEs) using the population-based DXA registry for the Province of Manitoba, Canada. The study population comprised 72 974 individuals aged 40 yr and older with baseline DXA assessment between February 1999 and March 2018.

A limitation to incorporating AAC clinically is that its scoring requires trained experts and is time-consuming. We examined if our machine learning (ML) algorithm for AAC (ML-AAC24) is associated with a higher fall-associated hospitalisation risk in the Manitoba Bone Mineral Density (BMD) Registry.
View Article and Find Full Text PDFLipocalin-2 (LCN2) has three main variants; polyaminated (hLCN2) and non-polyaminated (C87A and R81E). The polyaminated form is proposed to positively influence energy control, whereas the non-polyaminated forms negatively impact energy control in mice. Glucocorticoids negatively affect glucose regulation and exercise has a positive effect.
View Article and Find Full Text PDFLipocalin-2 (LCN2), a hormone produced by adipocytes, osteoblasts, and renal tubular cells, is implicated in age-related diseases, including cardio-metabolic disease. To understand the role LCN2 may play in pathological states, we first need to elucidate the relationship between circulating LCN2 with indices of cardio-metabolic health during "normal" aging. This study examined the relationship between serum levels of LCN2, age, and cardio-metabolic measures across the adult lifespan in males and females.

The objective of this study was to describe the risk of a major adverse cardiovascular event (MACE, from linked health records) in patients attending routine bone mineral density (BMD) testing and meeting specific criteria based on age, BMD, height loss, or glucocorticoid use have a VFA in the Manitoba BMD Registry. The cohort included 10 250 individuals (mean age 75.

Consumption of total vegetable intake and vegetable types (yellow/orange/red [YOR], cruciferous, allium, green leafy vegetables [GLV], and legumes) were estimated using a validated food frequency questionnaire at baseline (1998).

Introduction: Dietary nitrate is potentially beneficial for cardiovascular, cerebrovascular, and nervous systems due to its role as a nitric oxide (NO) precursor. Increased nitrate intake improves cardiovascular health and therefore could protect against dementia, given the cardiovascular-dementia link.
Objective: To investigate the association between source-dependent nitrate intake and dementia-related mortality.

Background: Higher cruciferous vegetable intake is associated with lower cardiovascular disease risk in observational studies. The pathways involved remain uncertain. We aimed to determine whether cruciferous vegetable intake (active) lowers 24-h brachial systolic blood pressure (SBP; primary outcome) compared to root and squash vegetables (control) in Australian adults with mildly elevated BP (SBP 120-160 mmHg inclusive).
View Article and Find Full Text PDFPurpose: Cancer survival is improving, making optimal management of long-term treatment-related adverse effects increasingly important. Exercise and a healthy diet are beneficial and regularly recommended in cancer survivorship guidelines; however, few cancer survivors meet these recommendations so there is a need to explore why. This study aimed to understand experiences receiving exercise and diet support among Australian breast and prostate cancer survivors during and following treatment, and to explore what support they would like to receive.

This systematic review and meta-analysis aimed to determine the downstream impact of cardiovascular imaging results on medication use and adherence.
Methods: Searches were conducted across databases, including MEDLINE, PsychINFO, EMBASE, and relevant references up to 2024.

Purpose: Dietary nitrate intake is inversely related to numerous contributors towards frailty, including cardiovascular disease and poor physical function. Whether these findings extend to frailty remain unknown. We investigated if habitual nitrate intake, derived from plants or animal-based foods, was cross-sectionally associated with frailty in women.
View Article and Find Full Text PDFContext: The associations of vegetable and potato intakes with type 2 diabetes (T2D) appear to be nuanced, depending on vegetable types and preparation method, respectively.
Objective: We investigated the associations of total vegetable, vegetable subgroup, and potato intakes with (1) markers of T2D at baseline and (2) incident T2D cumulative over a 12-year follow-up period in Australian adults.
Methods: Using data from the Australian Diabetes, Obesity and Lifestyle Study, intakes of vegetables and potatoes were assessed via a food frequency questionnaire at baseline.
Importance: Identification of individuals at high risk for atherosclerotic cardiovascular disease within the population is important to inform primary prevention strategies.
Objective: To evaluate the prognostic value of routinely available cardiovascular biomarkers when added to established risk factors.
Design, Setting, And Participants: Individual-level analysis including data on cardiovascular biomarkers from 28 general population-based cohorts from 12 countries and 4 continents with assessments by participant age.
Scope: Higher intake of cruciferous and allium vegetables is associated with lower cardiometabolic risk. Little research has investigated the cardiometabolic effects of S-methyl cysteine sulfoxide (SMCSO), found abundant in these vegetables. This study hypothesizes that SMCSO will blunt development of metabolic syndrome features in mice fed high-fat feed.

We estimated the independent associations of auto-PVFx and auto-AAC primarily with incident major osteoporotic and secondarily with incident hip and any clinical fractures in 11 013 individuals (mean [SD] age 75.8 [6.
