Most (61%) ‘first time’ users did not fill another prescription in the next two years while 22% did so sporadically.
The research will be presented at the Thoracic Society of Australia and New Zealand (TSANZ) Conference which starts this Sunday in Melbourne.
The study was conducted by the Australian Centre for Asthma Monitoring, a collaborating unit of the Australian Institute of Health and Welfare based at the Woolcock Institute of Medical Research in Sydney. It analysed the anonymous Pharmaceutical Benefits Scheme (PBS) records of individuals who filled a prescription for preventer medications for asthma for the first time between July 2004 and June 2005, and their subsequent prescription activity over a period of two years. The most commonly used form of preventer medication is inhaled corticosteroids.
Professor Guy Marks, Head of Epidemiology Research at the Woolcock Institute, said the results indicated that the prevalence of one-time and sporadic use was highest in young adults (age 15-34 years) with regular use most common in adults aged 65 years and over.
“The PBS dataset is a valuable tool for assessing patterns of asthma medication use,” he said.
“Importantly this study shows that while guidelines recommend regular use of preventer medication, this certainly isn’t happening in the community. At least some of those people who are now using preventer medication sporadically, could be expected to benefit from regular use of this class of medications.
The results of the study will be presented at the upcoming Thoracic Society of Australia and New Zealand (TSANZ) Conference being held in Melbourne from March 30 to April 2.
Professor Marks will present the abstract titled Patterns Of Asthma Medication Use: An Australian Population-Based Longitudinal Cohort Study on the afternoon of Monday 31 March.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
