Spatial clustering of drug-resistant tuberculosis in Hunan province, China: an ecological studyThis study aimed to investigate the spatial distribution of drug-resistant tuberculosis (DR-TB) in Hunan province, China. An ecological study was conducted using DR-TB data collected from the Tuberculosis Control Institute of Hunan Province between 2012 and 2018.

Redressing ‘unwinnable battles’: Towards institutional justice capital in Australian child protectionAustralia’s history of negative child protection outcomes for children in state care highlights the sustained, systemic nature of serious harm. Situated in emerging conversations on structural challenges and state violence for parents involved in child protection systems, we trace the resources and barriers to responsive and ‘just’ child protection practice, highlighting how institutions can serve to compound disadvantage and injustice. We argue that addressing challenges such as access to advocacy at the level of the individual is to miss the underlying politics of oppression that serves to keep families marginalised.

Role of Tris-CaEDTA as an adjuvant with nebulised tobramycin in cystic fibrosis patients with Pseudomonas aeruginosa lung infections: A randomised controlled trialWe tested if disrupting iron utilisation by P. aeruginosa by adding the Tris-buffered chelating agent CaEDTA to nebulised tobramycin would enhance bacterial clearance and improve lung function in CF patients.

OPTIMUM study protocol: an adaptive randomised controlled trial of a mixed whole-cell/acellular pertussis vaccine scheduleCombination vaccines containing whole-cell pertussis antigens were phased out from the Australian national immunisation programme between 1997 and 1999 and replaced by the less reactogenic acellular pertussis (aP) antigens. In a large case-control study of Australian children born during the transition period, those with allergist diagnosed IgE-mediated food allergy were less likely to have received whole-cell vaccine in early infancy than matched population controls (OR: 0.77 (95% CI, 0.62 to 0.95)). We hypothesise that a single dose of whole-cell vaccine in early infancy is protective against IgE-mediated food allergy.

Djaalinj Waakinj (listening talking): Rationale, cultural governance, methods, population characteristics–an urban Aboriginal birth cohort study of otitis mediaThe majority of Australian Aboriginal and Torres Strait Islander (hereafter referred to as “Aboriginal”) people live in urban centres. Otitis media (OM) occurs at a younger age, prevalence is higher and hearing loss and other serious complications are more common in Aboriginal than non-Aboriginal children. Despite this, data on the burden of OM and hearing loss in urban Aboriginal children are limited.

Transplacental Innate Immune Training via Maternal Microbial Exposure: Role of XBP1-ERN1 Axis in Dendritic Cell Precursor ProgrammingWe recently reported that offspring of mice treated during pregnancy with the microbial-derived immunomodulator OM-85 manifest striking resistance to allergic airways inflammation, and localized the potential treatment target to fetal conventional dendritic cell (cDC) progenitors. Here, we profile maternal OM-85 treatment-associated transcriptomic signatures in fetal bone marrow, and identify a series of immunometabolic pathways which provide essential metabolites for accelerated myelopoiesis.

Lower Cord Blood IL-17 and IL-25, but Not Other Epithelial Cell-Derived Cytokines Are Associated with Atopic Dermatitis in InfancyThere is a growing need for early biomarkers that may predict the development of atopic dermatitis (AD). As alterations in skin barrier may be a primary event in disease pathogenesis, epithelial cell (EC) cytokines expression patterns may be a potential biomarker in early life to target allergy preventive strategies towards "at-risk" infants. The aim of this longitudinal investigation was to examine from birth over the course of infancy levels of the EC cytokines: thymic stromal lymphopoietin (TSLP), interleukin (IL)-33, IL-25, and IL-17 in infants at high-risk of AD due to maternal atopy.

Genetics, Transcriptomics and Meta-Taxonomics in Visceral LeishmaniasisVisceral leishmaniasis (VL) caused by parasites of the Leishmania donovani complex can be fatal in susceptible individuals. Understanding the interactions between host and pathogen is one way to obtain leads to develop better drugs and for vaccine development. In recent years multiple omics-based approaches have assisted researchers to gain a more global picture of this interaction in leishmaniasis. Here we review results from studies using three omics-based approaches to study VL caused by L. donovani in India.

Do sex hormones at birth predict later-life economic preferences? Evidence from a pregnancy birth cohort study: Hormones at birth and preferencesEconomic preferences may be shaped by exposure to sex hormones around birth. Prior studies of economic preferences and numerous other phenotypic characteristics use digit ratios (2D : 4D), a purported proxy for prenatal testosterone exposure, whose validity has recently been questioned. We use direct measures of neonatal sex hormones (testosterone and oestrogen), measured from umbilical cord blood (n = 200) to investigate their association with later-life economic preferences (risk preferences, competitiveness, time preferences and social preferences) in an Australian cohort (Raine Study Gen2).
