Background Sickle cell disease (SCD) is a genetic blood disorder characterized by abnormal hemoglobin S, leading to red blood cell deformities, chronic hemolysis, and frequent vaso-occlusive crises (VOC). While advancements in medical care have improved survival rates, adults with SCD continue to face substantial challenges in their quality of life (QoL) due to chronic pain, recurrent VOCs, and various complications. This study aimed to evaluate the health-related quality of life (HRQoL) in adult patients aged 14 years and above with SCD and identify key factors influencing patient outcomes using the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me).

Background: Unfractionated heparin (UFH) is the preferred anticoagulant agent in percutaneous coronary intervention (PCI) procedures for minimising the risk of thrombotic complications. Because of the narrow therapeutic range of UFH, some society guidelines have advocated the use of the activated clotting time (ACT) test to monitor anticoagulation intensity during PCI to reduce thrombotic and bleeding complications. We aimed to assess the current practice of UFH prescription and its monitoring in Australia and New Zealand (ANZ).

Background: Acute kidney injury (AKI) is associated with significant short- and long-term morbidity and mortality. In critically ill patients with sepsis, AKI tends to be more severe, more likely to require kidney replacement therapy (KRT), with less chance of recovery. Consequently, critically ill patients with sepsis-associated AKI (SA-AKI) have extended intensive care unit (ICU) stays and higher mortality rates.

Background And Objectives: Patients who were hospitalized with coronavirus disease 2019 (COVID-19) infection are at high risk of AKI and KRT, especially in the presence of CKD. The Dapagliflozin in Respiratory Failure in Patients with COVID-19 (DARE-19) trial showed that in patients hospitalized with COVID-19, treatment with dapagliflozin versus placebo resulted in numerically fewer participants who experienced organ failure or death, although these differences were not statistically significant. We performed a secondary analysis of the DARE-19 trial to determine the efficacy and safety of dapagliflozin on kidney outcomes in the overall population and in prespecified subgroups of participants defined by baseline eGFR.
