        Metagenomic Characterisation of the Gut Microbiome and Effect of Complementary Feeding on Bifidobacterium spp. in Australian Infants

        Complementary feeding induces dramatic ecological shifts in the infant gut microbiota toward more diverse compositions and functional metabolic capacities, with potential implications for immune and metabolic health. The aim of this study was to examine whether the age at which solid foods are introduced differentially affects the microbiota in predominantly breastfed infants compared with predominantly formula-fed infants.  ...

        Expert survey: safer research with parent survivors of child maltreatment

        Intergenerational trauma research typically focuses on parent survivors. No specific guidelines are available for conducting research with parent survivors despite potentially unique risks. To investigate research safety with parent survivors, we conducted an online survey of 38 researchers regarding experiences of parent survivors in their research, precautions taken, ethical review experiences, and researchers’ mental health during the project(s).  ...

        Superior immunogenicity of mRNA over adenoviral vectored COVID-19 vaccines reflects B cell dynamics independent of anti-vector immunity: Implications for future pandemic vaccines

        Both vector and mRNA vaccines were an important part of the response to the COVID-19 pandemic and may be required in future outbreaks and pandemics. The aim of this study was to validate whether immunogenicity differs for adenoviral vectored (AdV) versus mRNA vaccines against SARS-CoV-2, and to investigate how anti-vector immunity and B cell dynamics modulate immunogenicity.  ...

        Inflammation induces α1-adrenoceptor expression in peripheral blood mononuclear cells of patients with complex regional pain syndrome

        Persistent regional and systemic inflammation may promote pain and hyperalgesia in complex regional pain syndrome. In this study, we investigated whether stimulation of α1-adrenoceptors on peripheral blood mononuclear cells might contribute to this inflammatory state. ...

        Down syndrome and leukemia: from basic mechanisms to clinical advances

        Children with Down syndrome (DS, trisomy 21) are at a significantly higher risk of developing acute leukemia compared to the overall population. Many studies investigating the link between trisomy 21 and leukemia initiation and progression have been conducted over the last two decades. ...

        Celebrating 100 years of Immunology & Cell Biology – a special focus on the field of tumor immunology in Australia

        In this Commentary article, as part of the 100-year celebrations of the journal, we reflect on the contribution of articles published in ICB in the field of tumor immunology. A highlight is a series of interviews conducted with three Australian-based ICB authors who have contributed key papers over the years: Rajiv Khanna, Delia Nelson and Ian Frazer. ...

        Health behaviours associated with healthy body composition among Aboriginal adolescents in Australia in the ‘Next Generation: Youth Well-being study’

        This study described the distribution of healthy body composition among Aboriginal adolescents in Australia aged 10-24 years and examined associations with health behaviours and self-rated health. ...

        Community-wide versus school-based targeted deworming for soil-transmitted helminth control in school-aged children in Vietnam: the CoDe-STH cluster-randomised controlled trial

        Soil-transmitted helminth (STH) infection control programs typically consist of school-based preventive chemotherapy (PC) targeted to school-aged children. STH reservoirs in untreated community members contribute to ongoing transmission in children. The CoDe-STH (Community Deworming against STH) trial, conducted in Dak Lak province, Vietnam, between October 2019 and November 2020, aimed to determine whether community-wide mass drug administration (MDA) is more effective than school-based targeted PC in reducing STH prevalence and intensity in children. ...

        A hospital-based asynchronous ENT telehealth service for children with otitis media: Cost-minimisation and improved access

        The purpose of this study is to explore the effectiveness of a hospital-based asynchronous ear, nose, and throat telehealth service (the Ear Portal) in reducing cost and improving access for children with otitis media. ...

        Immune checkpoint therapy responders display early clonal expansion of tumor infiltrating lymphocytes

        Immune checkpoint therapy (ICT) causes durable tumour responses in a subgroup of patients, but it is not well known how T cell receptor beta (TCRβ) repertoire dynamics contribute to the therapeutic response.  ...
