Measuring the effect of RFID and marker recognition tags on cockroach (Blattodea: Blaberidae) behavior using AI-aided tracking.

Radio frequency identification (RFID) technology and marker recognition algorithms can offer an efficient and non-intrusive means of tracking animal positions. As such, they have become important tools for invertebrate behavioral research. Both approaches require fixing a tag or marker to the study organism, and so it is useful to quantify the effects such procedures have on behavior before proceeding with further research.

The Treatment Experiences of Vegetarians and Vegans with an Eating Disorder: A Qualitative Study.

Background: Vegetarianism and veganism have long been tied to disordered eating and are frequently considered to be methods of limiting available food choices. Health professionals specializing in eating disorder treatment may modify their treatment practices to support their vegetarian or vegan clients. However, there are no formally recognized clinical guidelines for the treatment of eating disorders in these groups.

Cryopreserved human alternatively activated macrophages promote resolution of acetaminophen-induced liver injury in mouse.

Acute liver failure is a rapidly progressing, life-threatening condition most commonly caused by an overdose of acetaminophen (paracetamol). The antidote, N-acetylcysteine (NAC), has limited efficacy when liver injury is established. If acute liver damage is severe, liver failure can rapidly develop with associated high mortality rates.

Tumour DNA methylation markers associated with breast cancer survival: a replication study.

Background: Tumour DNA methylation has been investigated as a potential marker for breast cancer survival, but findings often lack replication across studies.

Methods: This study sought to replicate previously reported associations for individual CpG sites and multi-CpG signatures using an Australian sample of 425 women with breast cancer from the Melbourne Collaborative Cohort Study (MCCS). Candidate methylation sites (N = 22) and signatures (N = 3) potentially associated with breast cancer survival were identified from five prior studies that used The Cancer Genome Atlas (TCGA) methylation dataset, which shares key characteristics with the MCCS: comparable sample size, tissue type (formalin-fixed paraffin-embedded; FFPE), technology (Illumina HumanMethylation450 array), and participant characteristics (age, ancestry, and disease subtype and severity).

Excipient lung disease with transient severe pulmonary hypertension in a healthcare professional injecting crushed oxycodone tablets.

Excipient lung disease (ELD) is a rare cause of pulmonary hypertension that occurs due to the intravenous injection of crushed tablets. We present the case of a healthcare professional in her late 30s who presented with a fever in the setting of a bacteraemia. During her hospital admission, she established a pattern of transient hypoxia and hypotension, with resolution without targeted management or clear cause identified.

Evaluation of agreement between common clustering strategies for DNA methylation-based subtyping of breast tumours.

Aims: Clustering algorithms have been widely applied to tumor DNA methylation datasets to define methylation-based cancer subtypes. This study aimed to evaluate the agreement between subtypes obtained from common clustering strategies.

Materials & Methods: We used tumor DNA methylation data from 409 women with breast cancer from the Melbourne Collaborative Cohort Study (MCCS) and 781 breast tumors from The Cancer Genome Atlas (TCGA).

Efficacy and safety of a whole lung lavage program for artificial stone silicosis.

Background: The incidence of silicosis has increased due to occupational silica exposure from artificial stone, with no treatments proven to halt or reverse the disease. Whole lung lavage (WLL) involves the instillation of fluid into the lungs to wash out silica particles and disease-causing inflammatory cells. This study aimed to determine the feasibility, safety, and possible benefit of WLL in patients with artificial stone silicosis.

Paediatric health system impact of an early respiratory viral season in Eastern Ontario, Canada: A descriptive analysis.

Objectives: We examined trends in patient volumes and care intensity among children admitted with laboratory-confirmed respiratory viral infections over 5 years in Ottawa, following the most recent and intense respiratory viral season experienced throughout the Ontario paediatric health system.

Methods: This was a retrospective cohort study of patients at the Children's Hospital of Eastern Ontario (CHEO) in Ottawa, who were diagnosed with a laboratory-confirmed respiratory viral infection in the first 72 h of admission between October 22, 2017 and March 25, 2023. Their admissions were stratified by age groups and level of care intensity, based on unit of admission and/or additional ventilatory needs, with Level 3 patients requiring intensive care unit admission, and evaluated for trends over six surveillance periods that began in Week 35 (early September) and ended in Week 34 (end-August) of the following year.

Regional ischaemic immune myopathy: unraveling a rare subtype of dermatomyopathy.

Regional ischaemic immune myopathy (RIIM) is a subtype of dermatomyopathy which has distinct histopathology features of regional muscle fibre necrosis and regeneration. This case report aims to provide an in-depth exploration of RIIM, emphasising its clinical features and the crucial role of muscle biopsy as a diagnostic investigation, as well as the potential role of immunomodulatory therapies.

Evaluation of waning of IgG antibody responses after rVSVΔG-ZEBOV-GP and Ad26.ZEBOV, MVA-BN-Filo Ebola virus disease vaccines: a modelling study from the PREVAC randomized trial.

rVSVΔG-ZEBOV-GP and Ad26.ZEBOV, MVA-BN-Filo are WHO-prequalified vaccination regimens against Ebola virus disease (EVD). Challenges associated with measuring long-term clinical protection warrant the evaluation of immune response kinetics after vaccination.

Biodiversity impacts of the 2019-2020 Australian megafires.

With large wildfires becoming more frequent, we must rapidly learn how megafires impact biodiversity to prioritize mitigation and improve policy. A key challenge is to discover how interactions among fire-regime components, drought and land tenure shape wildfire impacts. The globally unprecedented 2019-2020 Australian megafires burnt more than 10 million hectares, prompting major investment in biodiversity monitoring.

Clinic-Level Predictors of Psychotherapy Dosage in the Military Health System.

Objective: This study aimed to describe the demand for, supply of, and clinic processes associated with behavioral health care delivery in the Military Health System and to examine the clinic-level factors associated with receipt of a minimally adequate dosage of psychotherapy.

Methods: This retrospective study used administrative behavioral health data from eight military treatment facilities (N=25,433 patients; N=241,028 encounters) that were participating in a larger implementation study of evidence-based psychotherapy for posttraumatic stress disorder. Minimally adequate dosage of psychotherapy was defined in two ways: at least three sessions within a 90-day period and at least six sessions within a 90-day period.

Evaluating the mobile Mantram Repetition Program for veterans with PTSD: A multimethod randomized feasibility trial of self-directed versus text support delivery.

Objective: While mobile delivery can help increase access to evidence-based treatment for veterans with posttraumatic stress disorder (PTSD), feasibility and acceptability are of concern with the potential for high attrition rates and limited participation. The Mantram Repetition Program (MRP), a meditation-focused approach with documented efficacy for reducing symptoms of PTSD and insomnia, was adapted as a brief, mobile-delivered MRP (mMRP) training. This study assessed implementation indicators of mMRP and compared self-directed users of mMRP versus users who received additional text message support.

Co-designing a digital family-led intervention for delirium prevention and management in adult critically ill patients: An application of the double diamond design process.

Background: Co-designing healthcare interventions is gaining recognition as a novel and collaborative method. Co-design involves end-users from the start, ensuring that an intervention best meets their needs. Despite its potential benefits, this approach is not yet widely used in developing clinical interventions within intensive care units where the perspectives of patients, family members, and clinicians are crucial.
