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.

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.

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.

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 (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.

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).
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.

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 (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.

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.

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.
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-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.

Background: Oral health continues to be one of the most common and costly diseases in early childhood, and there is a need for further, innovative research.
Purpose: We explored the ways naturally living parents (those who embody the "natural" within their parenting ideology and behavior) navigated and perceived their children's oral health.
Methods: Twelve participants who identified as being "naturally living parents" participated in semistructured interviews.
During the 2018-2020 Ebola virus disease outbreak in Democratic Republic of the Congo, a phase 3 trial of the Ad26.ZEBOV, MVA-BN-Filo Ebola vaccine (DRC-EB-001) commenced in Goma, with participants being offered the two-dose regimen given 56 days apart. Suspension of trial activities in 2020 due to the COVID-19 pandemic led to some participants receiving a late dose 2 outside the planned interval.

Similar to various viruses, COVID-19 has been implicated in the pathogenesis of autoimmune diseases. This article highlights the potential for infections including the SARS-CoV-2 virus to induce exacerbations of pre-existing autoimmune diseases or even potentially unmask de novo autoimmune diseases in particular anti-synthetase syndrome (ASSD) in predisposed individuals.

The involvement of neurodegeneration in MS underscores the need for effective neuroprotective approaches necessitating identification of new therapeutic targets. Herein, we applied an integrated elemental analysis workflow to human MS-affected spinal cord tissue utilising multiple inductively coupled plasma-mass spectrometry methodologies.
