Study protocol for controlled human infection for penicillin G against Streptococcus pyogenes: a double-blinded, placebo-controlled, randomised trial to determine the minimum concentration required to prevent experimental pharyngitis (the CHIPS trial)

Regular intramuscular benzathine penicillin G injections have been the cornerstone of rheumatic heart disease (RHD) secondary prophylaxis since the 1950s. As the pharmacological correlate of protection remains unknown, it is difficult to recommend changes to this established regimen. Determining the minimum effective penicillin exposure required to prevent Streptococcus pyogenes infection will accelerate development of new long-acting penicillins for RHD prevention as well as inform opportunities to improve existing regimens. The CHIPS trial will address this knowledge gap by directly testing protection afforded by different steady state plasma concentrations of penicillin in an established model of experimental human S. pyogenes pharyngitis.

Modelling vitamin D food fortification among Aboriginal and Torres Strait Islander peoples in Australia

Low vitamin D intake and prevalence of serum 25-hydroxyvitamin D concentration <50 nmol/L among Aboriginal and Torres Strait Islander peoples highlight a need for public health strategies to improve vitamin D status. Since few foods contain naturally occurring vitamin D, food fortification could be a suitable strategy. We aimed to model vitamin D food fortification scenarios among Aboriginal and Torres Strait Islander peoples.

Active counselling for child and adolescent mental health: A qualitative investigation

Talk-based psychotherapy and physical activity are both recognised as effective treatments for child and adolescent mental illness. Despite this, talk therapy and physical activity are rarely integrated-an approach hereafter termed "active counselling (AC)" -in clinical practice for youth mental health. The purpose of this study was to explore parents' perspectives of AC for their child who had been receiving this type of therapy from a provider in Australia. Parental perceptions were also used to identify possible psychological mechanisms underpinning the effects of AC.

Parental Experiences of Having a Child Diagnosed With Septo-Optic Dysplasia

Septo-optic dysplasia (SOD) is a congenital disorder affecting 1 in 10,000 births, defined by the presence of at least two of a clinical triad, consisting of optic nerve hypoplasia, midline brain defects and pituitary hormone deficiency. Children with SOD may have vision impairment, hormonal deficiencies, developmental disorders, or epilepsy, but the clinical picture is highly variable. The complexity of SOD, its interplay with family factors, and the need for multiple specialty commitments can make the diagnosis period a challenging time for families.

Lung volumes, gas transfer and oscillometry after preterm birth: systematic review and meta-analysis

Small airway and lung parenchymal abnormalities frequently occur following preterm birth but are commonly missed by spirometry. Static lung volumes, diffusing capacity of the lung for carbon monoxide (D LCO) and oscillometry provide a more precise characterisation of these conditions. We hypothesised that differences in these measures exist between individuals born preterm and at term and we aimed to systematically review the literature to identify and quantify these differences in lung function.

Exercise Sensations During Moderate-Intensity Heart-Rate-Clamped Cycling in Graded Hypoxia: A Qualitative Approach

To explore how graded hypoxia affects perceptual sensations during heart-rate-clamped cycling using qualitative methods.

Caregiver broader autism phenotype does not moderate the effect of early caregiver-mediated support on infant language outcomes

Caregiver-mediated supports in general have shown mixed evidence for enhancing language outcomes in infants at higher likelihood of autism. While caregivers play a substantial role in caregiver-mediated supports, little is known about whether caregivers' own subclinical autistic features - known as broader autism phenotype - may moderate infant language outcomes. 

Does exercise in cool water cause a higher risk of hypoglycaemia than in thermoneutral conditions in type 1 diabetes?

The aim of this study was to test the hypothesis that exercise in cool water results in a greater decrease in blood glucose concentration than in thermoneutral water or on land in individuals with type 1 diabetes.

Physiological responses to exercise in survivors of preterm birth: a meta-analysis

Survivors of preterm birth (<37 weeks' gestation) have low peak oxygen uptake, a global measure of aerobic fitness and an established predictor of increased morbidity and mortality. However, little is known about other cardiopulmonary outcome measures in this population. We addressed the hypothesis that preterm birth is associated with abnormal respiratory, cardiovascular and metabolic responses to exercise, as assessed by cardiopulmonary exercise testing, via a systematic review and meta-analysis.

Predicting Problem Gambling in Young Men: The Impact of Sports Gambling Frequency and Internalizing Symptoms

Young men aged 18-25 years are at disproportionately increased risk for gambling problems compared to their older or female counterparts. The unique mechanisms that precipitate these problems in this group remain unclear. Data from the largest longitudinal cohort study on Australian men's health (the Ten to Men Study) were used to identify the psychosocial, health-related, and gambling-related behavioral predictors of problem gambling severity in 265 young men aged 18-25 years. Hierarchical multiple ordinal logistic regression analyses found these predictors to explain a moderate proportion of variance in problem gambling severity.
