Quantitative measures of subjective wellbeing for adolescents: a scoping review and synthesis of comparable data

Efforts to promote adolescent wellbeing are of increasing global interest. Although the ability to measure wellbeing is essential for identifying disparities between and within populations, and for tracking progress in improving wellbeing, the best way to measure this elusive concept in adolescents is unclear.

Impact of Host and Bacterial Metabolism on Antibiotic Susceptibility

Antimicrobial resistance (AMR) is a global healthcare emergency, directly causing 1.3 million deaths per year and predicted to increase dramatically over the coming decades. Understanding the molecular mechanisms underpinning antibiotic resistance is central to approaches for AMR surveillance and diagnosis in a clinical laboratory.

Clinical decision rules for diagnosis of Streptococcus pyogenes sore throat in Fiji: a prospective diagnostic accuracy study

Acute rheumatic fever is an immune-mediated condition triggered by Streptococcus pyogenes sore throat and possibly skin infection, with a substantial burden in resource-limited settings. Clinical decision rules (CDRs) are commonly used to guide antibiotic treatment of sore throat based on signs and symptoms, but their diagnostic accuracy varies by study and setting. This work aimed to assess the accuracy of multiple CDRs in Fiji to diagnose S. pyogenes sore throat.

Indigenous infants in remote Australia retain an ancestral gut microbiome despite encroaching Westernization

Studies of traditional Indigenous compared to 'Western' gut microbiomes are underrepresented, and lacking in young children, limiting knowledge of early-life microbiomes in different cultural contexts. Here we analyze the gut metagenomes of 50 Indigenous Australian infants (median age <one year) living remotely with variable access to Western foods, compared to age- and sex-matched non-Indigenous infants living in urban Australia.

What Parents, Teachers and Clinicians Know About the Features of Developmental Dyslexia and Its Intervention: A Scoping Review

Despite decades of research, misconceptions about developmental dyslexia remain widespread among those responsible for identifying and supporting affected children. Identifying the nature and persistence of these beliefs is essential to improving practice and policy. We conducted a scoping review to map the understanding of developmental dyslexia among teachers, parents and clinicians by identifying their beliefs about its features and interventions.

Planetary health and Indigenous sovereignty: exploring the theory of change of the Healthy Environments and Lives (HEAL) network in Western Australia

This paper outlines the theory of change which underpins the Western Australian (WA) hub of the Healthy Environments and Lives (HEAL) network. HEAL is an Australian national research initiative that aims to address the health impacts of climate and environmental change. The WA hub's theory of change is focused on improving the health and well-being of the planet and people, including children, through centring Indigenous sovereignty, voices and ways of knowing and being in research, policy development and service provision.

Patient-reported perceptions, experiences and preferences around intravenous and oral antibiotics for the treatment of Staphylococcus aureus bacteremia: a descriptive qualitative study

There is growing evidence to support partial oral antibiotic treatment of severe infections such as Staphylococcus aureus bacteremia, but clinical practice is slow to adopt this paradigm. We know little about how patients with severe infection experience and perceive intravenous and oral antibiotics in terms of quality of life and clinical effectiveness. We performed a qualitative study to elicit patients' views on treatment with intravenous and oral antibiotics, aiming to provide insights that could inform collaborative treatment decision-making.

Population pharmacokinetics of penicillin G: insights into increased clearance at low concentrations to guide development of improved long-acting formulations for syphilis

Although benzylpenicillin (penicillin G) is listed by the World Health Organization as an Essential Medicine, dose optimization is a persistent challenge, especially for long-acting intramuscular formulations. Maintaining sustained antibiotic exposure at target concentrations is crucial for secondary chemoprophylaxis of rheumatic heart disease and treatment of syphilis.

Is Systemic Dissemination of BCG Following Neonatal Vaccination Required for Protection Against Mycobacterium tuberculosis?

Tuberculosis (TB) is caused by Mycobacterium tuberculosis (Mtb) and is a leading cause of death. BCG is the only licensed TB vaccine. Preclinical studies have shown that in adults, intravenous administration of BCG improves protection against TB. We hypothesize that intradermal administration of BCG to the human newborn leads to low-grade BCG bacteremia and that this systemic dissemination improves protection against Mtb infection. This hypothesis is based on supporting observations including animal and human studies. It is a testable hypothesis and offers to deliver immediately actionable insight to advance the global efforts against TB.

The Association Between Obesity and COVID-19 Severity in Children Differed Between SARS-CoV-2 Variants: A Multicountry Hospital-based Observational Study

Obesity was a risk factor for severe COVID-19 in children during early outbreaks of ancestral SARS-CoV-2 and the Delta variant. However, the relationship between obesity and COVID-19 severity during the Omicron wave remains unclear.
