The interaction of genetic and environmental contributions to immunological traits and their association with atopic disease remain unclear. Flow cytometry and in vitro cytokine responses were used to characterize immune profiles from 93 school-aged twin pairs. Using an established twin pair analytical strategy, the genetic and environmental influences on immunological traits were evaluated, along with their association with atopy. Our findings suggest strong genetic influence on several traits, particularly B cell abundance. In contrast, cytokine responses from in vitro stimulations appeared mainly shaped by environmental exposures.
Cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) is an ultrarare genetic condition causing developmental epileptic encephalopathy characterized by seizures and motor and intellectual disabilities. No disease-modifying therapies are available, and treatments focus mainly on symptom management to improve quality of life.
Sex hormones, such as oestrogen and testosterone, display significant immune modulatory properties. This is highly relevant for transgender (trans) people who undergo gender-affirming hormone (GAH) treatment. However, only a limited number of studies have evaluated the immunological impact of GAH treatments, and almost none have assessed the impact in trans young people.
This paper presents a comprehensive cardiac safety framework for early clinical development of Streptococcus pyogenes (Group A Streptococcus) vaccines, endorsed by the Strep A Vaccine Global Consortium and the Australian Strep A Vaccine Initiative. Given historical concerns about vaccine-associated acute rheumatic fever, we have established standardized echocardiography protocols integrated with clinical assessment for monitoring cardiac safety in early-phase vaccine trials.
Adaptive behaviour change is central to improving population health, yet poor adoption of health-enhancing behaviours contributes to noncommunicable diseases and so remains a global concern. Research on physical activity behaviour change has continued to expand and evolve since the turn of the millennium, guided by diverse theoretical approaches-from social cognitive theories, organismic dialectical approaches such as Self-Determination Theory, dual-process frameworks, and integrated practical models and taxonomies.
Language development is critical for children's life chances. Promoting parent-child interactions is suggested as one mechanism to support language development in the early years. However, limited evidence exists for a causal effect of parent-child interactions on children's language development.
Carcinogenic effects of ultraviolet radiation (UVR) with reference to skin cancer are the basis of widely implemented recommendations to avoid sun exposure. Whether the benefits of "restrictive sun policies" outweigh their potential harms due to diminished beneficial effects of sunlight exposure remain a matter of controversy.
Shared decision-making between patients and primary healthcare professionals positively impacts health outcomes. However, people with intellectual disability face additional barriers and require supported shared decision-making (SSDM) to participate. Little is known about how healthcare professionals use SSDM with this population. This paper explores the facilitators and barriers experienced, and strategies/resources employed by healthcare professionals working with people with intellectual disability.
The Australian Therapeutic Goods Administration approved the use of nirsevimab, a long-acting monoclonal antibody for the prevention of Respiratory Syncytial Virus (RSV), in November 2023. Western Australia (WA) implemented a combination of nirsevimab administration strategies designed to protect all infants starting in April 2024, before the epidemic season. We developed a dynamic transmission model to predict the impact of WA's RSV immunisation program on infant hospitalisations.
A comprehensive understanding of specific factors contributing to variability in responsiveness of children with autism to interventions is paramount for making evidence-based clinical and policy decisions. This meta-analysis examined child and family characteristics, as well as intervention design factors, associated with outcomes of behavioral interventions for children with autism.
