Future of Acute Severe Ulcerative Colitis-A Narrative Review.

While corticosteroids have led to significant reduction in ASUC mortality over the last few decades, they are associated with significant side effects and up to 30% of patients have steroid refractory ASUC, which means we require safer and better therapies for patients with ASUC. Several salvage therapies have been proposed in guidelines; however, we lack high quality head-to-head randomised controlled trials to assess effectiveness and safety of these agents. Furthermore, the role of newer novel agents in ASUC management is unclear.

Lung-kidney axis in cystic fibrosis: Early urinary markers of kidney injury correlate with neutrophil activation and worse lung function.

Background: Adult people with cystic fibrosis (PwCF) have a higher risk of end-stage kidney disease than the general population. The nature and mechanism of kidney disease in CF are unknown. This study quantifies urinary kidney injury markers and examines the hypothesis that neutrophil activation and lung infection are associated with early kidney injury in CF.

Upadacitinib induction is effective and safe in ulcerative colitis patients including those with prior exposure to tofacitinib: a multicenter real-world cohort study.

Background/aims: Upadacitinib is a novel selective Janus kinase inhibitor approved for use in ulcerative colitis. Clinical trials had rigorous criteria and excluded many patient subgroups. Given limited real-world effectiveness data, we examined outcomes of patients treated with upadacitinib for ulcerative colitis in a real-world population.

The impact of the COVID-19 pandemic on hospital presentations in adults with gastrointestinal infections at a tertiary centre in Australia.

Background: The COVID-19 pandemic resulted in the enactment of substantial public health measures aimed at reducing the transmission of respiratory viruses. The impact of these measures on gastrointestinal (GI) infections remains unexplored.

Aims: To determine whether there was a change in the number of patients presenting to The Royal Melbourne Hospital with GI infections during the COVID-19 pandemic compared to the year prior.

Milk osteopontin has high iron-binding capacity and facilitates iron absorption in intestinal cells.

Insufficient absorption of iron and the consequent development of iron deficiency have serious health consequences. Hence, identification and development of iron delivery systems that can increase the bioavailability and uptake of dietary iron are important. Osteopontin (OPN) is an acidic and highly phosphorylated integrin-binding protein found in milk where it exists as a full-length protein and as N-terminally derived fragments.
