Introduction

Recognising and acting on the connection to Country as a determinant of Indigenous peoples’ well-being is necessary to improve health inequities. Indigenous Australians experience a greater burden of chronic liver disease and poorer outcomes due to ongoing impacts of colonisation across determinants of health. This is exacerbated by a gradient in health outcomes based on remoteness, lack of specialist healthcare services and barriers to access. Our research aims to explore better ways to provide chronic liver disease screening and surveillance for very remote Indigenous Australian communities using non-invasive technologies On-Country.

Methods and analysis

Using an innovative combination of Indigenous and Quantitative research methodologies, this project involves 11 communities across four very remote sites in South Australia and Western Australia. The study comprises three parts: (1) site engagement with Aboriginal health services and remote communities; (2) a 12-month liver check (screening) phase and (3) a 24-month liver monitoring (surveillance) phase. The liver monitoring phase will use a stepped-wedge randomised controlled trial design where sites will have usual hepatocellular carcinoma (HCC) monitoring for a period of between 6 and 18 months and then On-Country monitoring for a period of between 6 and 18 months depending on treatment-sequence allocation. Recommended HCC monitoring involves 6 monthly liver ultrasounds and serum alpha-fetoprotein as per the site’s usual care processes, where participants travel to regional centres for liver ultrasound. On-Country monitoring will involve liver ultrasound and serum tumour markers provided On-Country every 6 months. The primary outcome is the difference in adherence to surveillance On-Country compared with usual care. In addition to statistical and health economic methods, yarning circles have been incorporated to explore participant experiences, their knowledge of liver disease and views about the On-Country monitoring.

Ethics and dissemination

This study was granted ethics approval from the relevant national and state Aboriginal Health Research Ethics Committees. Findings will be reported to all participants and will be disseminated to the broader community and local health services. Translation of outcomes will be supported by key Indigenous Australian and healthcare stakeholders, including peak health bodies and consumer groups. Dissemination with the academic community will be through peer-reviewed publications and presentations at relevant conferences.

Effects of rehabilitation and behavior change interventions on physical capacity and physical activity behavior following lumbar surgery for degenerative disease: A systematic review and meta-analysis

by José Manuel García-Moreno, Tyler Adams, Amber Beynon, Janine Vlaar Olthuis, Stephan U. Dombrowski, Richelle Witherspoon, Niels Wedderkopp, Jeffrey J. Hébert

Background

Rehabilitation and behavior change interventions are commonly used after lumbar surgery to improve recovery, but their effects on physical capacity and physical activity remain unclear. This study aimed to investigate the effectiveness of rehabilitation and behavior change interventions on physical capacity and physical activity behavior in patients following lumbar surgery for degenerative disease.

Methods

EMBASE, MEDLINE, PsycINFO, and CENTRAL were searched from inception to September 2025 and reference lists were hand-searched. Randomized controlled trials assessing rehabilitation or behavior change interventions on physical capacity or physical activity behavior in adults with lumbar degenerative disc disease who underwent lumbar surgery were included. Review author pairs independently extracted data and assessed included studies. Risk of bias was assessed with the Cochrane tool, and study quality with the Grading of Recommendations Assessment, Development and Evaluation classification. Results were pooled using random-effects models and reported as standardized mean differences (SMD) with 95% confidence intervals (CI).

Results

Exercise was more effective than minimal or usual care in improving trunk extension endurance in the immediate term (SMD, 1.54; 95% CI, 0.93–2.16). Supervised exercise outperformed self-directed exercise in improving trunk extension endurance in the immediate term (SMD, 1.28; 95% CI, 0.75–1.81). Psychologically informed rehabilitation was more effective than minimal or usual care in increasing physical activity levels in the intermediate term (SMD, 0.26; 95% CI, 0.02–0.49), but not in the immediate term (SMD, 0.17; 95% CI, −0.14 to 0.49). Physical activity advice did not increase physical activity levels compared to minimal or usual care in the immediate term (SMD, 0.21; 95% CI, −0.13 to 0.55). Prehabilitation was more effective than minimal or usual care in increasing physical activity levels in the intermediate term (SMD, 0.28; 95% CI, 0.03–0.53). Certainty of evidence ranged from low to moderate.

Conclusions

For adults with lumbar degenerative disease who underwent lumbar surgery, exercise, especially supervised programs, improved trunk extension endurance in the immediate term. Psychologically informed rehabilitation and prehabilitation increased physical activity levels in the intermediate term, while physical activity advice showed no benefit. Findings are limited by low certainty of evidence and high risk of bias.

Pressure Injuries and Skin Failure: The Search for Clarity

ABSTRACT

Skin failure is increasingly recognised across healthcare settings, yet its definition, diagnostic criteria and relationship to pressure injuries remain inconsistent with little interdisciplinary consensus. This lack of clarity complicates bedside assessment, documentation and quality reporting. Historically, pressure injuries were viewed as preventable events associated with inadequate care, but growing evidence shows that some wounds develop despite optimal preventive measures, particularly in patients with multimorbidity or limited physiological reserve. This article will review the historical development of skin failure and how it is intertwined with contrasting theories of pressure injury formation that began in the 19th century. We will track the proliferation of definitions and overlapping terms that muddle contemporary documentation and classification, and demonstrate why a unified definition is urgently needed. Skin failure represents the intersection of tissue deformation with systemic vulnerability including hypoperfusion, inflammation, vascular dysfunction, oedema, medication effects, immune compromise, nutritional depletion and age-related changes. A meaningful and practical definition must span all healthcare environments and patient populations, supporting accurate diagnosis and equitable evaluation of care quality. We outline a call to action that includes interdisciplinary consensus, standardised terminology and the development of predictive tools that integrate physiologic data, advanced analytics, and patient-centered outcomes across the healthcare continuum.

Investigating the effects of cannabinoids for the reduction of inflammation and sickle cell disease pain (CRISP); A protocol for a randomized double-blind placebo-controlled study

by Jordan Bellis, Lydia Monk, Ritika Jhawar, Galia Pollock, Angela Liu, Charleen Jacobs-McFarlane, Brittany McCrary, Jeffrey Glassberg, Susanna Curtis

Sickle Cell Disease (SCD) is a hemoglobinopathy affecting millions of people globally. Pain, both acute and chronic, affects over half of those living with SCD, but treatment of chronic pain is an ongoing challenge. While opioid treatments are widely used for chronic pain, it’s efficacy is limited, so alternatives must be explored. This protocol outlines a procedure for investigation of dronabinol, an FDA-approved synthetic tetrahydrocannabinol (THC), for the treatment of pain in patients living with SCD and chronic pain. The study is an 8-week, randomized, double-blind placebo-controlled study which aims to assess both the efficacy and safety of this opioid alternative to pain treatment. The study will also track biomarkers of inflammation as THC has demonstrated anti-inflammatory properties, and inflammation is a driver of SCD pain and disease severity. Results from this study have the potential to further clinical understanding of cannabinoids for pain management in Sickle Cell Disease treatment and spark new questions for research.

Exploring factors contributing to patient decision-making in the care journey to elective hernia care in Kenya

by Helen W. Li, Jesse Kiprono Too, Sarah Nyanchama Nyariki, Charles Nathan Nessle, Sara Malone, Rachel Matsumoto, Teddy Ashibende Aurah, Jeffrey A. Blatnik, JoAnna Hunter-Squires, Ivan Seno Saruni

Background

Capacity for elective general surgical care is an important reflection of a health system’s ability to meet a population’s surgical needs and is currently known to be inadequate in many low- and middle-income countries. Patient agency is a key, understudied factor which shapes how and when patients ultimately decide to engage with formal care. Understanding factors which influence patient care seeking activity can have important implications for how current and future health systems may be utilized. This study aims to explore how patients approach the navigation and triage of their elective hernia condition within the Kenyan surgical care system.

Methods

We conducted a qualitative study of 38 convenience-sampled patients diagnosed with an elective hernia condition at a tertiary referral hospital in Kenya between November 2023 and March 2024. We utilized Braun and Clarke’s six-step model of thematic analysis to generate key themes across the phases of care seeking, reaching and receiving as modeled in the Three Delays Framework.

Results

We identified three main cross-cutting themes including (1) the flow of power from patients to providers, and vice versa, take the form of consent or knowledge, respectively; (2) trust is a limited currency required for patients to engage with formal care; and (3) internal and external contextual factors remain the foundation for patient-provider care activities. We incorporated these themes together in a framework which illustrates the cyclical nature by which each factor feeds back on the others, ultimately affecting patient care.

Conclusions

Fluctuating flows of patient power and trust interacts with existing infrastructural context to influence the ability of a health system to generate care. Recognizing the interaction of these key factors may have important bearing on the successful implementation of any larger systemic efforts or policies to improve access to elective surgical care.

Analytical validation of a homologous recombination deficiency signature (HRDsig) in pan-tumor tissue samples

by Wenshu Li, Jeffrey A. Leibowitz, Shuoguo Wang, Louisa Walker, Chang Xu, Kuei-Ting Chen, Alexa B. Schrock, Jason Hughes, Nimesh Patel, Julia A. Elvin, Lauren L. Ritterhouse, Ethan Sokol, Garrett Frampton, Lucas Dennis, Bahar Yilmazel, Brennan Decker

Homologous recombination repair (HRR) is a cellular pathway for high-fidelity double strand DNA break repair that uses the sister chromatid as a guide to ensure chromosomal integrity and cell viability. Deficiency in the HRR pathway (HRD) can sensitize tumors to poly (ADP-ribose) polymerase inhibitors (PARPi) and platinum-based chemotherapy, offering an avenue to identify patients who may benefit from targeted therapies. HRD signature (HRDsig) is a pan-solid-tumor biomarker on the FoundationOne®CDx (F1CDx®) assay that employs a DNA scar-based approach to calculate a score based on copy number features (e.g., segment size, oscillation patterns, and breakpoints per chromosome arm) and does not rely on HRR gene alterations, enabling detection of genomic and epigenetic mechanisms of HRD. After finalizing the HRDsig algorithm, analytical validation was conducted in a CAP-accredited, CLIA-certified laboratory on 278 solid tumor and normal tissue specimens. HRDsig results were compared with an independent HRD biomarker, defined by the presence of a reversion mutation restoring HRR gene function. In this evaluation, 100 HRD-positive and 126 HRD-negative samples showed a positive percent agreement of 90.00% and a negative percent agreement of 94.44%. The limit of detection (LoD) was estimated at 23.04% tumor purity, with the limit of blank (LoB) confirmed as zero in 60 normal tissue replicates. Reproducibility testing on 11 positive and 11 negative samples across multiple labs, reagent lots, and sequencers yielded agreement in 99.49% of positive and 99.73% of negative replicates. HRDsig status remained consistent in the presence of interfering substances, demonstrating 100% concordance in spiked samples. These validation results underscore the high analytical concordance, low false-positive rate, and overall robustness of HRDsig for reliable assessment of homologous recombination deficiency.
