Article
Background: Emerging research suggests that quality of life (QOL) outcomes, such as maintenance of independence, rather than length of life, are the main priority for many patients with end stage kidney disease (ESKD). There is therefore a need to focus on whether QOL for older patients on dialysis differs significantly from conservative kidney man...

Article
Full-text available
Shared decision making is important when deciding the appropriateness of dialysis for any individual, particularly for older patients with advanced CKD who have high mortality. Emerging evidence suggests that patients with advanced age, high comorbidity burden and poor functional status may not have any survival advantage on dialysis compared to th...
Article
Background and aims Preeclampsia (PE) is associated with life-long increased risk of cardiovascular disease. One of the main protective functions of high-density lipoprotein (HDL) is its role in reverse cholesterol transport. HDL-mediated cholesterol efflux capacity (CEC) is decreased during pregnancy in women with PE. Whether this persists postpar...
Article
Background As healthcare is responsible for 7% of Australia's carbon emissions, it was recognised that a policy implemented at St George Hospital, Sydney to reduce non-urgent pathology testing to two days per week and on other days only if essential, would also result in a reduction in carbon emissions. The aim of the study was to measure the impac...
Article
All units managing hypertensive pregnant women should maintain and review uniform departmental management protocols and conduct regular audits of maternal & fetal outcomes. The cause(s) of pre-eclampsia and the optimal clinical management of the hypertensive disorders of pregnancy remain uncertain; therefore, we recommend that every hypertensive pr...
Article
Objectives Hypertensive disorders of pregnancy are associated with subsequent increased risk of cardiometabolic disease. Adverse cardiometabolic measures are noted soon after hypertensive versus normotensive pregnancy (NP); to what degree these persist into a subsequent pregnancy (SP) is unknown. This study aimed to assess women’s physiology early...
