The risk of death from cardiovascular causes in people with type 2 diabetes mellitus remains around twice that in the general population, with heart failure a common event. In 2017, results from cardiovascular outcome trials in people with diabetes mellitus showed that some drugs have dual utility — reducing cardiovascular risk and improving glycaemic control.

Extracellular danger-associated molecular patterns signal to NOD-like receptors, but the exact signalling pathways remain unclear. The inflammasomes, a subgroup of these receptors, translate danger signals into inflammatory responses by maturing IL-1 and IL-18. In 2017, researchers reported novel functions of the mutual interaction between metabolism and the inflammasomes in health and disease.

The artificial pancreas — the automated closed-loop control of diabetes mellitus — made its first outpatient strides in 2011. In 2017, the results of long-term clinical trials on the artificial pancreas were published, the first hybrid commercial artificial pancreas system was approved and the artificial pancreas was tested under increasingly demanding conditions. Thus, artificial pancreas technology is here to stay.

Major advances in the management of all stages of upper tract urothelial carcinoma have been made in 2017. Radical nephroureterectomy can be valuable in patients with metastatic disease and adjuvant platinum-based chemotherapy can improve outcomes in those with advanced disease. Kidney-sparing surgery with early follow-up ureterorenoscopy has shown benefit in patients with low-grade tumours. Avoiding unnecessary ureterorenoscopy might decrease intravesical tumour recurrence.
