Risk Factors for Incident Kidney Disease in Older Adults: an Australian Prospective Population-Based Study.
To determine risk factors for incident chronic kidney disease (CKD) in a large population-based cohort. ⋯ This large population-based study found multiple modifiable and non-modifiable factors were independently associated with developing CKD. In the Australian setting, the risk of CKD was higher with regional residence. Differences according to socioeconomic status were predominantly explained by age, comorbidities and harmful health-related behaviours.

Case ReportsMusculoskeletal immune-related adverse events with use of checkpoint inhibitors in malignancy.
Immunotherapy has revolutionised the treatment of many malignancies. Along with their success, there have been inflammatory and immune-related adverse events (irAE). There is a paucity of literature describing the Australian experience of rheumatic irAE. ⋯ Rheumatic irAE are heterogenous clinical entities, which require further evaluation into classification, patient susceptibility and response. From our study, there was no clear clinical pattern. The present case series supports that rheumatic irAE may be associated with tumour response. However, there is still limited experience in rheumatic irAE management and outcomes.

ReviewPrescription trends and costs of diabetes medications in Australia between 2003 and 2019: an analysis and review of the literature.
Since the turn of the century, the prevalence of diabetes mellitus in Australia has increased, primarily due to rising rates of Type 2 diabetes. Simultaneously, the landscape of diabetes medications has evolved significantly. The change in prescribing trends and public spending on diabetes medications within Australia during this period are not well defined. ⋯ Our data show a large growth in the use of diabetes medications between 2003 and 2019. The rapid growth in dispensing of drugs with proven cardiovascular and renal benefits reflect the evolving approach of diabetes treatment, from a historical approach targeting glycaemic control alone, to a modern individualised approach targeting specific co-morbidities.

ReviewUnderstanding vaccine-induced thrombotic thrombocytopenia (VITT).
Vaccine-induced thrombotic thrombocytopenia (VITT) is a rare, but serious, syndrome characterised by thrombocytopenia, thrombosis, a markedly raised D-dimer and the presence of anti-platelet factor-4 (PF4) antibodies following COVID-19 adenovirus vector vaccination. VITT occurs at a rate of approximately 2 per 100 000 first-dose vaccinations and appears exceedingly rare following second doses. Our current understanding of VITT pathogenesis is based on the observations that patients with VITT have antibodies that bind to PF4 and have the ability to form immune complexes that induce potent platelet activation. ⋯ VITT can be associated with a high mortality rate and significant morbidity, but awareness and optimal therapy have significantly improved outcomes in Australia. A number of questions remain unanswered, including why VITT is so rare, reasons for the predilection for thrombosis in unusual sites, how long pathological antibodies persist, and the optimal duration of anticoagulation. This review will provide an overview of the presentation, diagnostic workup and management strategies for patients with VITT.

Observational StudyA mixed-method analysis of screening for Strongyloides stercoralis prior to immunosuppression: A problem of limited bandwidth?
Guidelines recommend screening for strongyloidiasis prior to immunosuppression in those at epidemiological risk, as hyperinfection following immunosuppression is often fatal. The uptake of this recommendation is unknown and we aimed to explore this in our setting. ⋯ We identified many missed opportunities to screen patients at risk of hyperinfection, particularly those most vulnerable. To improve screening, this study highlights the importance of reducing cognitive load by using decision-support tools, which may facilitate screening in vulnerable patients and in time-constrained settings.
