The discovery of tumor-derived neoantigens which elicit an immune response through major histocompatibility complex (MHC-I/II) binding has led to significant advancements in immunotherapy. While many neoantigens have been discovered through the identification of non-synonymous mutations, the rate of these is low in some cancers, including head and neck squamous cell carcinoma. Therefore, the identification of neoantigens through additional means, such as aberrant splicing, is necessary.

While research into animal models has prioritized treatments aimed at diminishing post-stroke damage, no studies have investigated the response to a severe stroke injury in a highly regenerative adult mammal. Here we investigate the effects of transient ischemia on adult spiny mice, Acomys cahirinus, due to their ability to regenerate multiple tissues without scarring.

Recently, researchers have used the Social Identity Approach to gain insight into these challenges, offering a psychological framework for understanding relations within and between response organisations. This study builds upon previous work by engaging responders from the emergency services in six discussion-based exercises.

The Precision Medicine sessions at the Pacific Symposium on Biocomputing (PSB) have consistently spotlighted progress in this domain. Our 2025 manuscript collection features algorithmic innovations that integrate data across scales and diverse data modalities, presenting novel techniques to derive clinically relevant insights from molecular datasets.

This has sparked interest in developing generalizable, standardized measurements of biodiversity-essentially a 'unit of nature'. We examine how such units are defined in the rapidly growing voluntary biodiversity credits market and present a framework exploring how biodiversity is quantified, how delivery of positive outcomes is detected and attributed to the investment and how the number of credits issued is adjusted to account for uncertainties.
View Article and Find Full Text PDFTumors utilize various mechanisms of HLA disruption in order to evade immune surveillance. Previous computational tools have interrogated specific aspects of this process, yet a holistic picture of HLA loss of heterozygosity (LOH), transcriptomic suppression, and alternative splicing has remained challenging. In a recent Nature Genetics study, Puttick and colleagues introduced MHC Hammer, a robust computational toolkit designed to dissect the complexities of HLA disruptions that mediate immune evasion in cancer.

Design: Retrospective population-based cohort study using data linkage.
Setting: 11 public hospitals in Queensland, Australia.
Enhancing the efficacy of immunotherapy in brain metastases (BrM) requires an improved understanding of the immune composition of BrM and how this is affected by radiation and dexamethasone. Our two-arm pilot study (NCT04895592) allocated 26 patients with BrM to either low (Arm A) or high (Arm B) dose peri-operative dexamethasone followed by pre-operative stereotactic radiosurgery (pSRS) and resection (n= 13 per arm). The primary endpoint, a safety analysis at 4 months, was met.

This study conducted a cost-effectiveness analysis to evaluate the relative clinical and economic merits of MWA compared to robotic-assisted partial nephrectomy (RA-PN) in the treatment of small renal masses.
Methods: A Markov state-transition model was constructed to simulate the progression of Australian patients with small renal masses treated with MWA versus RA-PN over a 10-year horizon.
Polycylic Aromatic Hydrocarbons (PAHs) are produced during the incomplete burning of organic materials. PAH sources include vehicle exhaust, tobacco smoke and waste incineration. Environmental and occupational exposures to PAHs are known to occur.

They range from densely populated areas (Cayman, Bermuda, Gibraltar) to land with no permanent inhabitants (British Antarctic Territory, South Georgia). However, they are linked by ecosystem instability (the permacrisis) including antimicrobial resistance (AMR), climate change and biodiversity disruption.

Study objectives were to explore (1) patient experiences of preoperative and postoperative treatment, (2) views of/involvement in prehabilitation and (3) sources and consistency of healthcare advice.
Design: Semi-structured interviews analysed using reflexive thematic analysis.
Antarctic krill (Euphausia superba Dana) is a keystone species in the Southern Ocean ecosystem, with ecological and commercial significance. However, its vulnerability to climate change requires an urgent investigation of its adaptive potential to future environmental conditions. Historical museum collections of krill from the early 20th century represent an ideal opportunity to investigate how krill have changed over time due to predation, fishing and climate change.
View Article and Find Full Text PDFImmune checkpoint blockade (ICB) has revolutionized cancer treatment; however, the mechanisms determining patient response remain poorly understood. Here, we used machine learning to predict ICB response from germline and somatic biomarkers and interpreted the learned model to uncover putative mechanisms driving superior outcomes. Patients with higher infiltration of T-follicular helper cells had responses even in the presence of defects in the MHC class-I (MHC-I).

A random-effects meta-analysis is the systematic synthesis of related effects from across a literature, producing an estimate of the distribution of effects in the population. We propose using the estimated mean and variance from a random-effects meta-analysis to inform the characterization of an observed effect size.

In rural and remote Australia, access to appropriate and timely mental health services has been identified as a major barrier to people seeking help for mental ill-health. From 2020 to 2021 a care navigation model, Navicare, was co-designed with rural and remote communities in the Greater Whitsunday Region of Central Queensland in Australia.

Sound therapy is a treatment intervention that is used to desensitize patients. However, as yet, there is a lack of understanding on how it is used in clinical practice, the different types of devices, or how to use them.

The objectives of this systematic review were to determine what health state utility values (HSUVs) are reported in the literature that can be used in economic evaluations of interventions for older people with AML, identify research gaps, and discuss directions for future research.

Type 1 diabetes (T1D) has a large genetic component, and expanded genetic studies of T1D can lead to novel biological and therapeutic discovery and improved risk prediction. In this study, we performed genetic association and fine-mapping analyses in 817,718 European ancestry samples genome-wide and 29,746 samples at the MHC locus, which identified 165 independent risk signals for T1D of which 19 were novel. We used risk variants to train a machine learning model (named T1GRS) to predict T1D, which highly differentiated T1D from non-disease and type 2 diabetes (T2D) in Europeans as well as African Americans at or beyond the level of current standards.
