Predicting immune protection against outcomes of infectious disease from population-level effectiveness data with application to COVID-19

Quantifying the extent to which previous infections and vaccinations confer protection against future infection or disease outcomes is critical to managing the transmission and consequences of infectious diseases. We present a general statistical model for predicting the strength of protection conferred by different immunising exposures (numbers, types, and strains of both vaccines and infections), against multiple outcomes of interest, whilst accounting for immune waning. 

How immunity shapes the long-term dynamics of influenza H3N2

Since its emergence in 1968, influenza A H3N2 has caused yearly epidemics in temperate regions. While infection confers immunity against antigenically similar strains, new antigenically distinct strains that evade existing immunity regularly emerge ('antigenic drift'). Immunity at the individual level is complex, depending on an individual's lifetime infection history.

A cross-sectional audit of the Australian community food environment highlights the prominent role of chain food outlets

Food retail and food service outlets can be part of a chain, or independently operated. Chain food outlets are likely to have the most influence over community food environments but have not been routinely identified in studies which map and monitor access to food, highlighting an important knowledge gap. This study aimed to identify the food retail and food service outlets present within metropolitan Perth, including presence of chain and independent food outlets; and examine differences across local governments. 

ESM-Q: A consensus-based quality assessment tool for experience sampling method items

The experience sampling method (ESM) is increasingly used by researchers from various disciplines to answer novel questions about individuals’ daily lives. Measurement best practices have long been overlooked in ESM research, and recent reviews show that item quality is often not reported in ESM studies. The absence of information about item quality may be partly explained by the lack of consensus on how ESM item quality should be evaluated.

Parents’ Disclosure of Their Child’s Health and Neurodevelopmental Conditions: A Systematic Review and Qualitative Metasynthesis

Parents of children with physical/mental health and/or neurodevelopmental conditions often need to make disclosure decisions for their child. Disclosure can bring benefits (e.g., support) but can also risk harm (e.g., stigma). This systematic review aimed to consolidate research regarding parents' disclosure experiences to better understand how to support parents during this process.

Polyamine depletion limits progression of acute leukaemia

Cancer cells are addicted to polyamines, polycations essential for cellular function. While dual targeting of cellular polyamine biosynthesis and polyamine uptake is under clinical investigation in solid cancers, preclinical and clinical studies into its potential in haematological malignancies are lacking. Here we investigated the preclinical efficacy of polyamine depletion in acute leukaemia.

Suppressing recurrence in Sonic Hedgehog subgroup medulloblastoma using the OLIG2 inhibitor CT-179

OLIG2-expressing tumor stem cells have been shown to drive recurrence in Sonic Hedgehog (SHH)-subgroup medulloblastoma (MB) and patients urgently need specific therapies to target this tumor cell population.

From Local to Systemic: The Journey of Tick Bite Biomarkers in Australian Patients

Tick bites and tick-related diseases are on the rise. Diagnostic tests that identify well-characterised tick-borne pathogens (TBPs) possess limited capacity to address the causation of symptoms associated with poorly characterised tick-related illnesses, such as debilitating symptom complexes attributed to ticks (DSCATT) in Australia. Identification of local signals in tick-bitten skin that can be detected systemically in blood would have both clinical (diagnostic or prognostic) and research (mechanistic insight) utility, as a blood sample is more readily obtainable than tissue biopsies.

Awake Supraglottic Airway Placement in Pediatric Patients for Airway Obstruction or Difficult Intubation: Insights From an International Airway Registry (PeDI)

Small case series have described awake supraglottic airway placement in infants with significant airway obstruction and difficult intubations. We conducted this study to determine outcomes when supraglottic airways were placed in awake children enrolled in the international Pediatric Difficult Intubation Registry including success of ventilation, success of tracheal intubation, and complications.

Malaria in Nepal: A Spatiotemporal Study of the Disease Distribution and Challenges on the Path to Elimination

Malaria incidence (MI) has significantly declined in Nepal, and this study aimed to investigate the spatiotemporal distribution and drivers of MI at the ward level. Data for malaria cases were obtained from the National Surveillance System from 2013 to 2021. Data for covariates, including annual mean temperature, annual mean precipitation, and distance to the nearest city, were obtained from publicly available sources. A Bayesian spatial model was used to identify factors associated with the spatial distribution of MI.
