Problem/background: Australian First Nations people experience disproportionate burdens of poor outcomes compared to non-First Nations people. Further, women living in remote communities face more barriers to care-seeking in pregnancy. Despite work being done in some remote communities, there is limited data exploring women's experiences of pregnancy care, thus a limited understanding of specific barriers and enablers to care-seeking for these women.

Background: Pediatric community-acquired pneumonia (CAP) can lead to long-term respiratory sequelae, including bronchiectasis. We determined if an extended (13-14 days) versus standard (5-6 days) antibiotic course improves long-term outcomes in children hospitalized with CAP from populations at high risk of chronic respiratory disease.

Methods: We undertook a multicenter, double-blind, superiority, randomized controlled trial involving 7 Australian, New Zealand, and Malaysian hospitals.

Article Synopsis
  • Bronchiectasis is a chronic lung disease affecting many, especially Indigenous populations in wealthy countries, and currently has no approved treatments.
  • A randomized controlled trial (RCT) aims to test the mucoactive agent erdosteine over 12 months to see if it reduces acute respiratory exacerbations in children and adults aged 2-49 with bronchiectasis.
  • The study will also evaluate the impact of erdosteine on quality of life, exacerbation duration, hospitalizations, lung function, and its overall cost-effectiveness.

Among large cetaceans in the Southern Hemisphere, fin whales were the most heavily exploited in terms of numbers taken during the period of intense industrial whaling. Recent studies suggest that, whilst some humpback whale populations in the Southern Hemisphere appears to have almost completely recovered to their estimated pre-whaling abundance, much less is known about the status of Southern Hemisphere fin whales. Circumpolar estimates in the 1990s suggest an abundance of about 5500 animals south of 60° S, while the IDCR/SOWER-2000 survey for the Scotia Sea and Antarctic Peninsula areas estimated 4670 fin whales within this region in the year 2000.
