Pedestrian Danger Index - a novel surrogate measure of pedestrian safety at unsignalized crossings.

Objective: The aims of the study are to assess pedestrian safety at unsignalized crossings and to develop a new surrogate measure to evaluate risks associated with vehicle-pedestrian interactions. The primary goal of developing a novel safety metric was to provide quick insights into pedestrian safety levels and conduct site assessments rather than predictive analyses.

Methods: Video surveys were conducted at multiple unsignalized crossing sites in Poland to record vehicle-pedestrian interactions.

Influence of food and lifestyle on the risk of developing inflammatory bowel disease.

Background: The Barwon area in Australia has one of the highest incidence rates of inflammatory bowel disease (IBD) and therefore is an ideal location to study the impact of environmental exposures on the disease's development.

Aim: To study these exposures prior to the development of IBD in a population-based cohort.

Method: One hundred and thirty-two incident cases (81 Crohn disease (CD) and 51 ulcerative colitis (UC)) from an IBD registry and 104 controls replied to the International Organization of Inflammatory Bowel Diseases environmental questionnaire.

Health Care Cost Analysis in a Population-based Inception Cohort of Inflammatory Bowel Disease Patients in the First Year of Diagnosis.

Background: There are limited prospective population-based data on the health care cost of IBD in the post-biologicals era. A prospective registry that included all incident cases of inflammatory bowel disease [IBD] was established to study disease progress and health cost.

Aim: To prospectively assess health care costs in the first year of diagnosis among a well-characterised cohort of newly diagnosed IBD patients.
