Reoperation for post hepatectomy complications.

Background: Reoperation for post hepatectomy complications is associated with high rates of morbidity and mortality. We aim to describe the frequency, indications, and risk factors for reoperation after liver resection in a single centre.

Methods: Perioperative data of 464 patients, who underwent elective hepatectomy from 2001 to 2020 at The Queen Elizabeth Hospital in South Australia, were retrospectively analysed.

Vitamin D supplementation compared to placebo in people with First Episode psychosis - Neuroprotection Design (DFEND): a protocol for a randomised, double-blind, placebo-controlled, parallel-group trial.

Background: People experiencing their first episode of psychosis are often deficient in vitamin D. Observational studies have reported an association between low vitamin D concentrations and poorer subsequent health outcomes in psychosis. A vitamin D deficiency in neonates and children has been linked to a later increased risk of schizophrenia and psychotic-like experiences.
