Background: Idiopathic inflammatory myopathies (IIMs) are a group of autoimmune diseases characterised by inflammation of skeletal muscle and other organ systems. They have high morbidity and mortality but, in part because of their rarity and heterogeneity, improving understanding and outcomes remains challenging. To address these problems, numerous IIM registries exist globally, but no national registry yet exists in Australia.

Background: Validated patient-reported outcome measures to assess disease impact in patients with adult idiopathic inflammatory myopathies (IIMs) are needed. The objective of this study was to assess the construct validity of PROMIS Pain Interference, Fatigue, and Physical Function measures in comparison with core disease activity measures.

Methods: Adults with IIM, excluding inclusion body myositis, from OMERACT Myositis Working Group (MWG) clinic sites completed PROMIS Short Form v1.

Background: International focus groups with patients with idiopathic inflammatory myopathies (IIM) conducted by the OMERACT Myositis Working Group over the years demonstrated the pain as an important symptom experienced by these patients. In this study, we aimed to examine the frequency and degree of pain interference, the aspects of daily life impacted by pain, and the factors associated with pain interference in adults with IIM.

Methods: This was a prospective observational study with two visits.

Background: A gap in the literature exists pertaining to a global research nurse/research midwife resources and communication skill set necessary to engage with participants of diverse populations and geographic regions in the community or home-based conduct of decentralized clinical trials.

Aims: An embedded mixed methods study was conducted to examine research nurse/research midwife knowledge base, experiences, and communication skill sets pertaining to decentralized trials across global regions engaged in remote research: the USA, Republic of Ireland, United Kingdom, and Australia.

Methods: An online survey was deployed across international research nurse/research midwife stakeholder groups, collecting demographics, decentralized trial experience, barriers and facilitators to optimal trial conduct, and the self-perceived communication competence (SPCC) and interpersonal communication competence (IPCC) instruments.

Introduction: Idiopathic inflammatory myopathies (known as 'myositis') are a group of rare sporadic inflammatory muscle disorders that significantly impact function and quality of life. There are no standardised approaches in the use of assistive technologies in myositis. This study was initiated to investigate current use and perceived value of assistive technology (AT) by people with myositis.

Objective: Inclusion body myositis (IBM) is a progressive late-onset muscle disease characterised by preferential weakness of quadriceps femoris and finger flexors, with elusive causes involving immune, degenerative, genetic and age-related factors. Overlapping with normal muscle ageing makes diagnosis and prognosis problematic.

Methods: We characterised peripheral blood leucocytes in 81 IBM patients and 45 healthy controls using flow cytometry.

Inclusion body myositis is the most common acquired myositis in adults, predominantly weakening forearm flexor and knee extensor muscles. Subclinical respiratory muscle weakness has recently been recognised in people with inclusion body myositis, increasing their risk of respiratory complications. Inspiratory muscle training, a technique which demonstrates efficacy and safety in improving respiratory function in people with neuromuscular disorders, has never been explored in those with inclusion body myositis.

Objectives: Inclusion body myositis (IBM) is a progressive inflammatory-degenerative muscle disease of older individuals, with some patients producing anti-cytosolic 5'-nucleotidase 1A (NT5C1A, aka cN1A) antibodies. Human Leukocyte Antigens (HLA) is the highest genetic risk factor for developing IBM. In this study, we aimed to further define the contribution of HLA alleles to IBM and the production of anti-cN1A antibodies.

Introduction: Inclusion body myositis (IBM) is a progressive inflammatory myopathy characterised by skeletal muscle infiltration and myofibre invasion by CD8 T lymphocytes. In some cases, IBM has been reported to be associated with a systemic lymphoproliferative disorder of CD8 T cells exhibiting a highly differentiated effector phenotype known as T cell Large Granular Lymphocytic Leukemia (T-LGLL).

Methods: We investigated the incidence of a CD8 T-LGL lymphoproliferative disorder in 85 IBM patients and an aged-matched group of 56 Healthy Controls (HC).

Introduction: Inclusion body myositis (IBM) is the most commonly acquired skeletal muscle disease of older adults involving both autoimmune attack and muscle degeneration. As exercise training can improve outcomes in IBM, this study assessed whether a combination of testosterone supplementation and exercise training would improve muscle strength, physical function and quality of life in men affected by IBM, more than exercise alone.

Methods: This pilot study was a single site randomised, double-blind, placebo-controlled, crossover study.

Objectives: Sporadic Inclusion Body Myositis (IBM) is an inflammatory muscle disease affecting individuals over the age of 45, leading to progressive muscle wasting, disability and loss of independence. Histologically, IBM is characterised by immune changes including myofibres expressing major histocompatibility complex molecules and invaded by CD8 T cells and macrophages, and by degenerative changes including protein aggregates organised in inclusion bodies, rimmed vacuoles and mitochondrial abnormalities. There is currently no cure, and regular exercise is currently the only recognised treatment effective at limiting muscle weakening, atrophy and loss of function.

Background: As nurses, we identify our profession as a caring one, but how does this identity translate from a conceptual definition, to real-world practice for the Clinical Research Nurse?

Aim: To offer a novel, four-point conceptual model that encapsulates the Clinical Research Nurse's intrinsic value, active leadership, and direct contribution to high quality, person-centered, safe care, addressing current misperceptions of research nursing.

Methods: This paper describes the provision of 'care', safely delivered by the Clinical Research Nurse through a four-point conceptual model and case-driven example.

Discussion: Clinical research nursing is conceptualized within the domains of Care and Trust, Role, Impact, and Integration.

Background: There is a global call for more inclusive clinical research that is representative of all populations, particularly those historically under-represented or under-served. A lack of broad representation results in disproportionate health outcomes and limits the applicability and translation of research findings.

Aim: Identify and describe barriers to participation across the research lifecycle and consider the role of the Clinical Research Nurse (CRN) in promoting inclusivity, including for Aboriginal and Torres Strait Islander Peoples within Australia.

In inflammatory myopathies, the self-reactive immune cells involved in muscle aggression have been studied mostly using histological assessment of muscle biopsy sections; this methodology provides the advantage of visualizing and identifying cells within the tissue, but it does not allow further investigation. To gain access to live and isolated cells, many studies utilized blood samples; however, in the absence of biological tools to discriminate the leukocytes associated with the autoimmune process from those that emerged from responses against pathogens, the information observed on circulating immune cells often lacks in specificity, and thus result interpretation may prove difficult. In order to selectively retrieve self-reactive immune cells, we developed a protocol to isolate live leukocytes from human muscle biopsies, which allows for further analysis using a large range of methodologies.
