A validated risk stratification tool for detecting high-risk small bowel Crohn's disease.

Background: Delays in Crohn's disease (CD) diagnosis are positively associated with ileal location and an increased risk of complications.

Aim: To develop a simple risk assessment tool to enable primary care physicians to recognise potential ileal CD earlier, shortening the delay to specialist investigation METHODS: Three cohorts were acquired for this study. Cohort 1 included 61 patients retrospectively identified with ileal CD between 2000 and 2010 and 78 matched controls drawn from a cohort referred for investigation of abdominal symptoms.

Seasonality, temperature and pregnancy oral glucose tolerance test results in Australia.

Background: The oral glucose-tolerance test (OGTT) is currently the standard method for diagnosis of gestational diabetes (GDM). We conducted a post hoc analysis using the Australian Hyperglycemia and Adverse Pregnancy Outcome (HAPO) data to determine seasonal variations in OGTT results, the consequent prevalence of GDM, and association with select perinatal parameters.

Method: Women enrolled in the Australian HAPO study sites (Brisbane and Newcastle) from 2001 to 2006 were included if OGTT results between 24 to 32 weeks gestation were available (n = 2120).

Perinatal immunoprophylaxis in babies born to hepatitis B virus-positive mothers in Queensland Australia: A data linkage study.

Vertical transmission from mother-to-child is an important mode of hepatitis B virus (HBV) infection, accounting for up to half of all incident cases globally. We evaluated the uptake of HBV neonatal vaccination and immunoglobulin delivery in Queensland, Australia, between 2001 and 2013. We identified HBV-positive mothers using linked notifiable conditions, hospitalisation, and perinatal administrative data.
