Azithromycin Augments Bacterial Uptake and Anti-Inflammatory Macrophage Polarization in Cystic Fibrosis.

Background: Azithromycin (AZM) is widely being used for treating patients with cystic fibrosis (pwCF) following clinical trials demonstrating improved lung function and fewer incidents of pulmonary exacerba-tions. While the precise mechanisms remain elusive, immunomodulatory actions are thought to be involved. We previously reported impaired phagocytosis and defective anti-inflammatory M2 macrophage polarization in CF.

Antimicrobial stewardship: Prescribing across the primary care health professions.

We examined the patterns of antibiotic prescribing by medical and non-medical prescribers (dentists, nurse practitioners, and midwives) in Australia. We explored trends in the dispensed use of antibiotics (scripts and defined daily dose [DDD] per 1000 population/day) by Australian prescribers over the 12-year period, 2005-2016. We obtained data on dispensed prescriptions of antibiotics from registered health professionals subsidized on the Pharmaceutical Benefits Scheme (PBS).

Redox Homeostasis in Well-differentiated Primary Human Nasal Epithelial Cells.

Oxidative stress (OS) in the airway epithelium is associated with inflammation, cell damage, and mitochondrial dysfunction that may initiate or worsen respiratory disease. Redox regulation maintains the equilibrium of pro-oxidant/antioxidant reactions but can be disturbed by environmental exposures. The mechanism(s) underlying the induction and impact of OS on airway epithelium and how these influences on respiratory disease is poorly understood.

Resveratrol and Astaxanthin Protect Primary Human Nasal Epithelial Cells Cultured at an Air-liquid Interface from an Acute Oxidant Exposure.

Oxidative stress (OS) in the airway epithelium is associated with cell damage, inflammation, and mitochondrial dysfunction that may initiate or worsen respiratory disease. However, it is unclear whether exogenous antioxidants can provide protection to the airway epithelium from OS. Resveratrol and astaxanthin are nutritional compounds that have shown diverse benefits including protection against OS and inflammation in various situations.

Environmentally persistent free radicals enhance SARS-CoV-2 replication in respiratory epithelium.

Epidemiological evidence links lower air quality with increased incidence and severity of COVID-19; however, mechanistic data have yet to be published. We hypothesized air pollution-induced oxidative stress in the nasal epithelium increased viral replication and inflammation. Nasal epithelial cells (NECs), collected from healthy adults, were grown into a fully differentiated epithelium.

Factors in childhood associated with lung function decline to adolescence in cystic fibrosis.

Background: Despite improvements in general health and life expectancy in people with cystic fibrosis (CF), lung function decline continues unabated during adolescence and early adult life.

Methods: We examined factors present at age 5-years that predicted lung function decline from childhood to adolescence in a longitudinal study of Australasian children with CF followed from 1999 to 2017.

Results: Lung function trajectories were calculated for 119 children with CF from childhood (median 5.

Effect of nusinersen on respiratory function in paediatric spinal muscular atrophy types 1-3.

Introduction: Nusinersen is used in spinal muscular atrophy (SMA) to improve peripheral muscle function; however, respiratory effects are largely unknown.

Aim: To assess the effects of nusinersen on respiratory function in paediatric SMA during first year of treatment.

Methods: A prospective observational study in paediatric patients with SMA who began receiving nusinersen in Queensland, Australia, from June 2018 to December 2019.

Anti-inflammatory effects of lenabasum, a cannabinoid receptor type 2 agonist, on macrophages from cystic fibrosis.

Background: Lenabasum is an oral synthetic cannabinoid receptor type 2 agonist previously shown to reduce the production of key airway pro-inflammatory cytokines known to play a role in cystic fibrosis (CF). In a double-blinded, randomized, placebo-control phase 2 study, lenabasum lowered the rate of pulmonary exacerbation among patients with CF. The present study was undertaken to investigate anti-inflammatory mechanisms of lenabasum exhibits in CF macrophages.

Clinical outcomes of an integrated primary-secondary model of care for individuals with complex type 2 diabetes: a non-inferiority randomised controlled trial.

Aims/hypothesis: The aim of the study was to determine if a Beacon model of integrated care utilising general practitioners (GPs) with special interests could achieve similar clinical outcomes to a hospital-based specialist diabetes outpatient clinic.

Methods: This pragmatic non-inferiority multisite randomised controlled trial assigned individuals with complex type 2 diabetes to care delivered by a Beacon clinic or to usual care delivered by a hospital outpatient department, in a 3:1 ratio. Owing to the nature of the study, researchers were only blinded during the allocation process.

A comparison of EQ-5D-3L population norms in Queensland, Australia, estimated using utility value sets from Australia, the UK and USA.

Purpose: To provide population norms for the EQ-5D-3L by age and gender based on a representative adult sample in Queensland, Australia; to assess differences in health-related quality of life by applying the Australian, UK and USA value sets to these data; and to assess differences in utility scores for key preventive health indicators.

Methods: A cross-sectional computer-assisted telephone interview survey (March-June 2011) with 5,555 adults. Respondents rated their impairment (none, moderate, severe problems) across five domains (mobility, self-care, usual activities, pain and discomfort, anxiety or depression) using the validated EQ-5D-3L health-related quality of life instrument.

Hospital admissions, emergency department utilisation and patient activation for self-management among people with diabetes.

Aims: To assess the relationship between patient activation for self-management and admissions to hospital or attendances at emergency departments among people with diabetes, after controlling for other known associations.

Methods: Patients were randomly selected from Australia's National Diabetes Services Scheme and invited to participate in the Living with Diabetes Study, which is a longitudinal survey providing a comprehensive examination of health care utilisation, well-being and disease progression. Data was collected for 3951 participants.

Communicating with the coroner: how religion, culture, and family concerns may influence autopsy decision making.

Based on coronial data gathered in the state of Queensland in 2004, this article reviews how a change in legislation may have impacted autopsy decision making by coroners. More specifically, the authors evaluated whether the requirement that coronial autopsy orders specify the level of invasiveness of an autopsy to be performed by a pathologist was affected by the further requirement that coroners take into consideration a known religion, culture, and/or raised family concern before making such an order. Preliminary data reveal that the cultural status of the deceased did not affect coronial autopsy decision making.

Patterns and determinants of influenza and pneumococcal immunisation among adults with chronic disease living in Queensland, Australia.

Using findings from a random, computer assisted telephone survey of households, this paper examines influenza and pneumococcal immunisation coverage and predictors of immunisation in 2203 adults with asthma, diabetes or a cardiovascular condition living in Queensland, Australia. 47% and 31% of high-risk persons were immunised against influenza and pneumococcus respectively. Immunisation coverage varied across chronic conditions and increased with age, being significantly higher for those aged 65 years and older and consequently eligible for free vaccination.

Gender differences in social network size and satisfaction in adults in their 70s.

Strong social support is associated with lower mortality and morbidity and better self-rated health in later life. The aim of this study was to compare social network size and satisfaction in men (N = 2589) and women (n = 3152), aged 72-78 years. Women reported significantly larger networks (Difference 1.

The role of patient activation in frequent attendance at primary care: a population-based study of people with chronic disease.

Objective: This study explores a range of relevant socio-demographic, physical and psychological factors in a unique examination of the risk factors for frequent attendance at primary care. The impact of patient activation for self-management on health service utilisation is of particular interest.

Methods: A population-based sample of people with chronic disease from Queensland, Australia, was interviewed using computer assisted telephone surveying.

Symptoms reported by women in midlife: menopausal transition or aging?

Objective: The aim of this study was to determine which symptoms commonly reported by women at midlife are associated with the menopausal transition, after adjusting for aging, life events, sociodemographics, and lifestyle factors.

Methods: Middle-aged women participating in the Australian Longitudinal Study on Women's Health between 1996 (survey 1, ages 45-50 y) and 2007 (survey 5) were included in the analyses if natural menopause status could be determined at any survey (n = 8,649 of 13,716 participants). Natural menopause status was determined from reported menstruation patterns.

Increasing the information available to coroners: the effect on autopsy decision-making.

This paper details research completed in 2007 which investigated autopsy decision-making in a death investigation. The data was gathered during the first year of operation in Queensland, Australia, of a new Coroners Act which changed the process of death investigation in three ways which are important to this paper. First, it required a greater amount of information to be gathered at the scene by police: this included a thorough investigation of the circumstances of the death, including statements from witnesses, friends and family, as well as evidence gathering at the scene.

The coronial system in Queensland: the effects of new legislation on decision-making.

The purpose of this article is to detail research completed in 2007 which investigated the way in which coroners made decisions in a death investigation, with a particular focus on their autopsy decision-making. The data were gathered during the first year of operation of a new Coroners Act in Queensland, Australia, which required a greater amount of information to be gathered at the scene by police, and this included a thorough investigation of the circumstances of the death, including statements from witnesses, friends and family, as well as evidence-gathering at the scene. This article addresses the outcomes of that increased information on coronial decision-making in three ways: first, whether or not the greater amount of information offered to coroners enabled them to be less reliant on full internal autopsies to establish cause of death; secondly whether certain factors were more influential in decision-making; and thirdly, whether the information gathered at the scene negates the need for full internal autopsies in many situations, irrespective of the decision-making by coroners.
