It is unclear whether this is due to the ageing global population alone, with several environmental factors increasingly implicated in changing prevalence rates. Large data sets have been used nationally and globally to help predict future disease burden.

Digital pathology has seen a proliferation of deep learning models in recent years, but many models are not readily reusable. To address this challenge, we developed WSInfer: an open-source software ecosystem designed to streamline the sharing and reuse of deep learning models for digital pathology. The increased access to trained models can augment research on the diagnostic, prognostic, and predictive capabilities of digital pathology.

Context: Gestational diabetes mellitus (GDM) is a complex obstetric condition affecting localized glucose metabolism, resulting in systemic metabolic dysfunction.

Objective: This cross-sectional study aimed to explore visceral adipose tissue (VAT) as an integral contributor to GDM, focusing on elucidating the specific contribution of obesity and GDM pathology to maternal outcomes.

Methods: Fifty-six nulliparous pregnant women were recruited, including normal glucose tolerant (NGT) (n = 30) and GDM (n = 26) participants.

Background: Little is known about the end-of-life (EOL) experience and specialist palliative care use patterns of patients with haematological malignancies (HMs) in New Zealand.

Aims: This retrospective analysis sought to examine the quality of EOL care received by people with HMs under the care of Auckland District Health Board Cancer Centre's haematology service and compare it to international data where available.

Methods: One hundred consecutive adult patients with HMs who died on or before 31 December 2019 were identified.
