Atrial Fibrillation in Kidney Failure: Challenges in Risk Assessment and Anticoagulation Management.

Management of atrial fibrillation (AF) is a clinical conundrum in people with kidney failure. Stroke risk is disproportionately high, but clinicians have a limited armamentarium to improve outcomes in this population in whom there is a concurrently high bleeding risk. Direct oral anticoagulants may have a superior benefit-risk profile compared with vitamin K antagonists in people on hemodialysis.

Ultrafiltration for acute heart failure.

Background: Pharmacotherapies such as loop diuretics are the cornerstone treatment for acute heart failure (AHF), but resistance and poor response can occur. Ultrafiltration (UF) is an alternative therapy to reduce congestion, however its benefits, efficacy and safety are unclear.

Objectives: To assess the effects of UF compared to diuretic therapy on clinical outcomes such as mortality and rehospitalisation rates.

Misclassification of calcium status in end-stage kidney disease using albumin-adjusted calcium levels.

Background: Albumin-adjusted calcium remains widely used in clinical practice with guidelines for chronic kidney disease (CKD) mineral bone disorder recommending the use of serum calcium for monitoring. This is despite ionized calcium being the biologically active fraction. This study aimed to investigate the ability of total calcium and albumin-adjusted calcium to correctly assign calcium status in stage 5/5D CKD across non-dialysis, haemodialysis and peritoneal dialysis patients.

Validation of two depression screening instruments in a sleep disorders clinic.

Study Objectives: Depression is a commonly diagnosed comorbidity in sleep disorder clinics. However, screening instruments for major depressive episode (MDE) have not been validated in this setting. We aimed to validate the Hospital Anxiety and Depression Scale (HADS) and the Beck Depression Inventory - Fast Screen (BDI-FS) with the Mini International Neuropsychiatric Interview (MINI) in patients with suspected obstructive sleep apnea (OSA).

Depression may reduce adherence during CPAP titration trial.

Study Objectives: Depression is a risk factor for medication non-compliance. We aimed to identify if depression is associated with poorer adherence during home-based autotitrating continuous positive airway pressure (autoPAP) titration.

Design: Mixed retrospective-observational study.
