Background: The risk-benefit balance of statin use in healthy older people is uncertain. We describe the baseline characteristics of the STAREE (Statins in Reducing Events in the Elderly) trial, which is a randomized, double-blind, placebo-controlled trial among community-dwelling older people; the trial evaluated the effect of atorvastatin 40 mg for the prevention of major cardiovascular events (cardiovascular death, nonfatal myocardial infarction or stroke), and on disability-free survival (survival free of both dementia and persistent physical disability).

Methods And Results: STAREE enrolled people aged ≥70 years from 1583 general practices across Australia with no history of clinical cardiovascular disease, diabetes, or dementia.

Aims: Cardiovascular disease (CVD) remains a significant public health concern, influenced by both genetic susceptibility and lifestyle factors. Integrating genetic risk information into clinical practice shows promise but has yielded mixed results regarding its impact on CVD prevention and management. This systematic review aimed to assess the impact of providing genetic CVD risk information on health behaviours, psychological outcomes, and risk factors.

Background: Management of type 1 diabetes (T1D) requires the use of insulin, which can cause hypoglycaemia (low blood glucose levels). While most hypoglycaemic episodes can be self-treated, all episodes can be sudden, inconvenient, challenging to prevent or manage, unpleasant and/or cause unwanted attention or embarrassment. Severe hypoglycaemic episodes, requiring assistance from others for recovery, are rare but potentially dangerous.

Article Synopsis
  • Recent trials show that aspirin for preventing heart disease often leads to more bleeding risks than benefits, particularly in the general population.
  • This study analyzed data from the ASPREE trial, focusing on individuals with a high genetic risk for coronary artery disease (CAD).
  • Findings revealed that those in the highest genetic risk group experienced a significant reduction in CAD events with aspirin, without increased bleeding risk, suggesting aspirin may be beneficial for high-risk individuals.

Article Synopsis
  • Global insulin requirements for type 2 diabetes were expected to rise by over 20% from 2018 to 2030, but recent increases in alternative diabetes treatments may influence actual insulin use and costs.
  • A nationwide study in Australia from 2003 to 2023 revealed fluctuating insulin utilization, with an initial increase followed by a significant decrease in both insulin use and costs, particularly after 2015.
  • The findings suggest that if similar trends are present globally, actual insulin needs and expenses may be lower than previously projected.

Background And Aims: The Semaglutide Effects on Cardiovascular Outcomes in People with Overweight or Obesity (SELECT) trial demonstrated significant reductions in cardiovascular outcomes in people with cardiovascular disease (CVD) and overweight or obesity (but without diabetes). However, the cost of the medication has raised concerns about its financial viability and accessibility within healthcare systems. This study explored whether use of semaglutide for the secondary prevention of CVD in overweight or obesity is cost-effective from the Australian healthcare perspective.

Article Synopsis
  • The study aimed to create prediction models to identify women with gestational diabetes mellitus (GDM) who are at high risk for developing type 2 diabetes (T2DM) after giving birth.
  • Using data from 1,299 women in the LIVING study, the researchers developed two models—one for during pregnancy and one for after birth—based on glucose tests, medical history, and biometric data.
  • The models showed strong predictive ability, with the antenatal model achieving an AUC of 0.76 and the postnatal model an AUC of 0.85, indicating they can effectively identify women at risk for T2DM; however, further validation is necessary before they can be widely used.

Article Synopsis
  • There is a notable lack of geographic and racial diversity in clinical trials, particularly due to the dominance of the U.S. and Europe, which affects the research's relevance to the Asia-Pacific region where 60% of cardiometabolic disease cases are found.
  • The study reviewed various cardiometabolic trials published from 2011 to 2020 to analyze the representation of Asian participants and authors from the Asia-Pacific region.
  • Results indicated that only 8.3% of trial participants were of Asian descent and APAC authorship was low, though there was a slight upward trend in Asian participation; significant underrepresentation continues to be an issue that requires attention.
