Background: Anaphylaxis is a potentially life-threatening allergic reaction, with presentations to emergency departments (EDs) increasing across Australia. Understanding the features of those presenting with anaphylaxis and aspects related to its optimal clinical management across the admission, treatment and discharge settings is needed to minimise its impact. We aimed to evaluate the nature and management of presentations related to anaphylaxis across two Australian EDs.

Background: Electrically assisted bicycles (e-bikes) have become increasingly popular and may facilitate active commuting and recreational cycling.

Objective: To evaluate the physical activity levels and usage characteristics of e-bikers and conventional cyclists under real-world conditions.

Methods: We conducted a prospective observational study in Germany to examine the effects of e-biking compared with conventional cycling on reaching the World Health Organization (WHO) target for physical activity-at least 150 min of moderate-to-vigorous physical activity (MVPA) per week.

Shoulder disorders are very common musculoskeletal conditions. Few studies have focused on the costs associated with shoulder disorders, and the economic burden has never been established in a nationwide cost-of-illness study.

Introduction: Adequate responsiveness and knowledge of the minimal important change (MIC) is essential when using patient-reported outcome measures to assess treatment efficacy.

Objective: The objective of this study was to evaluate the responsiveness and MIC of common outcomes in patients with subacromial impingement syndrome undergoing arthroscopic subacromial decompression.

Methods: At baseline and 6 months after surgery, patients completed the Oxford Shoulder Score (OSS), EQ-5D 5-level utility index, EQ visual analogue scale, Fear-Avoidance Belief Questionnaire Physical Activity subscale (FABQ-PA), assessed pain (pain visual analogue scale), and Subjective Shoulder Value.
