Association of Year-to-Year Lipid Variability With Risk of Cognitive Decline and Dementia in Community-Dwelling Older Adults.

Background And Objectives: Lipid metabolism in older adults is affected by various factors including biological aging, functional decline, reduced physiologic reserve, and nutrient intake. The dysregulation of lipid metabolism could adversely affect brain health. This study investigated the association between year-to-year intraindividual lipid variability and subsequent risk of cognitive decline and dementia in community-dwelling older adults.

Egg Consumption and Mortality: A Prospective Cohort Study of Australian Community-Dwelling Older Adults.

Background/objectives: Egg consumption in adults has been linked with a modestly increased risk of all-cause and CVD mortality. However, evidence on adults aged 65 y+ is limited. The objective of this study was to investigate the association between egg intake and mortality in community-dwelling older adults.

The incidence of cardiac surgery in adults with treated kidney failure in Australia: a retrospective cohort study.

ObjectiveKidney failure increases people's risk of cardiovascular disease, sometimes requiring cardiac surgery. The aim of this study was to estimate the risk of cardiac surgery for adults with treated kidney failure in comparison with the general population in Australia.MethodsWe performed a population-based retrospective cohort study by linking data between the Australia and New Zealand Dialysis and Transplant Registry and the Australian and New Zealand Society of Cardiac and Thoracic Surgeons Cardiac Surgery Database, for 2010-2019.

Effect of 3 Different Daily Protein Intakes in a 2-Meal Eating Pattern on Protein Turnover in Middle Age and Older Adults: A Randomized Controlled Trial.

Background: Reduced meal frequency patterns have become popular for weight loss, maintenance, and improving cardiometabolic health. The extended fasting windows with these dietary patterns could lead to greater protein breakdown, which is a concern for middle-aged and older adults who may need higher protein intakes to maintain or increase net protein balance.

Objectives: This study aimed to quantify muscle and whole-body protein kinetic responses to 3 different daily protein intakes within a 2-meal eating pattern.

Effects of statins on kidney function in older adults.

Background: The effect of statin therapy on kidney function among older adults is unclear.

Objectives: To examine the association between statin use and changes in estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR), positive or negative, in an older adult cohort with versus without chronic kidney disease (CKD) at baseline.

Methods: This analysis included 18,056 participants aged ≥65 years with versus without CKD at baseline in a randomized trial of low-dose aspirin, who had no prior cardiovascular events, major physical disability, or dementia initially.
