Scoping review of exposure questionnaires and surveys in interstitial lung disease.

BACKGROUND: Many interstitial lung diseases (ILDs) have clear causal relationships with environmental and occupational exposures. Exposure identification can assist with diagnosis, understanding disease pathogenesis, prognostication and prevention of disease progression and occurrence in others at risk. Despite the importance of exposure identification in ILD, there is no standardised assessment approach. Many questionnaires are in clinical and research use, yet their utility, applicability, relevance and performance characteristics are unknown. OBJECTIVES: This scoping review aimed to summarise the available evidence relating to ILD exposure assessment questionnaires, identify research gaps and inform the content for a future single evidence-based ILD questionnaire. METHODS: A scoping review based on Arksey and O'Malley's methodological framework was conducted. ELIGIBILITY CRITERIA: Any questionnaire that elicited exposures specific to ILD was included. A modified COSMIN Risk of Bias Framework was used to assess quality. SOURCES OF EVIDENCE: Relevant articles were identified from MEDLINE and EMBASE up to 23 July 2023. RESULTS: 22 exposure questionnaires were identified, including 15 generally pertaining to ILD, along with several disease-specific questionnaires for hypersensitivity pneumonitis (n=4), chronic beryllium disease, sarcoidosis and silicosis (1 questionnaire each). For most questionnaires, quality was low, whereby the methods used to determine exposure inclusion and questionnaire validation were not reported or not performed. Collectively the questionnaires covered 158 unique exposures and at-risk occupations, most commonly birds, mould/water damage, wood dust, asbestos, farming, automotive mechanic and miners. Only five questionnaires also provided free-text fields, and 13 queried qualifiers such as temporality or respiratory protection. CONCLUSIONS: Designing a robust ILD-specific questionnaire should include an evidence-based and relevance-based approach to exposure derivation, with clinicians and patients involved in its development and tested to ensure relevance and feasibility.

Providing effective care and support for autistic adults with mental health issues.

Autism is a neurodevelopmental condition that is characterised by features such as persistent differences in social interaction and communication, specialised interests and sensory processing issues. It has been identified that autistic people are increasingly likely to experience various mental health issues, and often encounter challenges in accessing appropriate healthcare and a lack of understanding from healthcare professionals. This article explores the co-occurrence of autism and mental health issues in adults, and explains the role of nurses in providing care and support for this population.

A global land cover training dataset from 1984 to 2020.

State-of-the-art cloud computing platforms such as Google Earth Engine (GEE) enable regional-to-global land cover and land cover change mapping with machine learning algorithms. However, collection of high-quality training data, which is necessary for accurate land cover mapping, remains costly and labor-intensive. To address this need, we created a global database of nearly 2 million training units spanning the period from 1984 to 2020 for seven primary and nine secondary land cover classes. Our training data collection approach leveraged GEE and machine learning algorithms to ensure data quality and biogeographic representation. We sampled the spectral-temporal feature space from Landsat imagery to efficiently allocate training data across global ecoregions and incorporated publicly available and collaborator-provided datasets to our database. To reflect the underlying regional class distribution and post-disturbance landscapes, we strategically augmented the database. We used a machine learning-based cross-validation procedure to remove potentially mis-labeled training units. Our training database is relevant for a wide array of studies such as land cover change, agriculture, forestry, hydrology, urban development, among many others.

Providing the right support and care for male victims of domestic abuse.

This article seeks to update and expand on earlier work published by the author on the subject of domestic violence against men almost 15 years ago. Since 2008, the language associated with domestic abuse has moved on, with most documents such as the newly enacted Domestic Abuse Act 2021 using either gender-neutral or gender-inclusive pronouns. However, men who experience domestic abuse continue to feel stigmatised and ignored by a discourse and framework that are still largely female oriented and driven. The article proposes approaches that the nurse can use to support men who experience domestic abuse.

Anticipatory grief and bereavement: the perspective of an individual with autism.

Much has been written around the meaning and impact of grief and grieving on people's lives following the death of a person, and anticipatory grief/grieving is receiving increased attention in nursing and healthcare. However, the impact of anticipatory grief on an autistic male adult has received far less research exposure than that of neurotypical (non-autistic) adults. This article, 'written' in the form of a letter by the author to community nurses, seeks to address this. The intention is to initiate reflective discussions around anticipatory grief and grieving, as current and future support will be stimulated on the part of community nurses through dialogue between those on the autistic spectrum and community nurses. Ultimately, the aim of this article is to help improve the support provided by community nurses to autistic individuals.

Barriers to identifying occupational asthma among primary healthcare professionals: a qualitative study.

INTRODUCTION: Occupational asthma (OA) accounts for one in six cases of adult-onset asthma and is associated with a large societal cost. Many cases of OA are missed or delayed, leading to ongoing exposure to the causative agent and avoidable lung function loss and poor employment-related outcomes. Enquiry about work-related symptoms and the nature of work by healthcare professionals (HCPs) is limited, evident in primary and secondary care. Potential reasons cited for this are time pressure, lack of expertise and poor access to specialists. AIM: To understand organisational factors and beliefs and behaviours among primary HCPs that may present barriers to identifying OA. METHODS: We employed a qualitative phenomenological methodology and undertook 20-45 min interviews with primary HCPs in West Midlands, UK. We used purposive and snowball sampling to include general practitioners (GPs) and practice nurses with a range of experience, from urban and rural settings. Interviews were recorded digitally and transcribed professionally for analysis. Data were coded by hand, and thematic analysis was undertaken and determined theoretically until themes were saturated. RESULTS: Eleven HCPs participated (eight GPs, three nurses). Four themes were identified that were considered to impact on identification of OA: (1) training and experience, (2) perceptions and beliefs, (3) systems constraints, and (4) variation in individual practice. OA-specific education had been inadequate at every stage of training and practice, and clinical exposure to OA had been generally limited. OA-specific beliefs varied, as did clinical behaviour with working-age individuals with asthma. There was a focus on diagnosis and treatment rather than attributing causation. Identified issues regarding organisation of asthma care were time constraints, lack of continuity, referral pressure, use of guidelines and templates, and external targets. CONCLUSION: Organisation and delivery of primary asthma care, negative OA-related beliefs, lack of formal education, and exposure to OA may all currently inhibit its identification.

Beyond adverse outcome pathways: making toxicity predictions from event networks, SAR models, data and knowledge.

Adverse outcome pathways have shown themselves to be useful ways of understanding and expressing knowledge about sequences of events that lead to adverse outcomes (AOs) such as toxicity. In this paper we use the building blocks of adverse outcome pathways-namely key events (KEs) and key event relationships-to construct networks which can be used to make predictions of the likelihood of AOs. The networks of KEs are augmented by data from and knowledge about assays as well as by structure activity relationship predictions linking chemical classes to the observation of KEs. These inputs are combined within a reasoning framework to produce an information-rich display of the relevant knowledge and data and predictions of AOs both in the abstract case and for individual chemicals. Illustrative examples are given for skin sensitization, reprotoxicity and non-genotoxic carcinogenicity.

Real world experience of response to pirfenidone in patients with idiopathic pulmonary fibrosis: a two centre retrospective study.

INTRODUCTION: Pirfenidone has been shown to reduce the decline in forced vital capacity (FVC) compared to placebo in patients with idiopathic pulmonary fibrosis (IPF). Previous studies have suggested that patients with a more rapid decline in FVC during the period before starting pirfenidone experience the greatest benefit from treatment. The purpose of this retrospective observational study was to investigate the response to pirfenidone in IPF patients, comparing two groups stratified by the annual rate of decline in FVC % predicted prior to treatment. METHODS: Using the rate of decline in FVC % predicted in the 12 months prior to pirfenidone, patients were stratified into slow (<5%) or rapid (≥5%) decliner groups. Comparisons in the lung function response to pirfenidone in these two groups were performed. RESULTS: Pirfenidone resulted in no statistically significant reduction in the median annual rate of decline in FVC or FVC % predicted. In the rapid decliners, pirfenidone significantly reduced the median (IQR) annual rate of decline in FVC % predicted (-8.7 (-14.2 - -7.0) %/yr vs 2.0 (-7.1 - 6.0) %/yr; n=17; p<0.01). In the slow decliners, pirfenidone did not reduce the median (IQR) annual rate of decline in FVC % predicted (-1.3 (-3.2 - 1.3) %/yr vs -5.0 (-8.3 - -0.35) %/yr; n=17; p=0.028). CONCLUSIONS: We demonstrate the greater net effect of pirfenidone in IPF patients declining rapidly. We suggest that using an annual rate of decline in FVC of <5% and ≥5% may be useful in counselling patients with regard to pirfenidone treatment.

Outcome of Hospitalization for COVID-19 in Patients with Interstitial Lung Disease. An International Multicenter Study.

Rationale: The impact of coronavirus disease (COVID-19) on patients with interstitial lung disease (ILD) has not been established.Objectives: To assess outcomes in patients with ILD hospitalized for COVID-19 versus those without ILD in a contemporaneous age-, sex-, and comorbidity-matched population.Methods: An international multicenter audit of patients with a prior diagnosis of ILD admitted to the hospital with COVID-19 between March 1 and May 1, 2020, was undertaken and compared with patients without ILD, obtained from the ISARIC4C (International Severe Acute Respiratory and Emerging Infection Consortium Coronavirus Clinical Characterisation Consortium) cohort, admitted with COVID-19 over the same period. The primary outcome was survival. Secondary analysis distinguished idiopathic pulmonary fibrosis from non-idiopathic pulmonary fibrosis ILD and used lung function to determine the greatest risks of death.Measurements and Main Results: Data from 349 patients with ILD across Europe were included, of whom 161 were admitted to the hospital with laboratory or clinical evidence of COVID-19 and eligible for propensity score matching. Overall mortality was 49% (79/161) in patients with ILD with COVID-19. After matching, patients with ILD with COVID-19 had significantly poorer survival (hazard ratio [HR], 1.60; confidence interval, 1.17-2.18; P = 0.003) than age-, sex-, and comorbidity-matched controls without ILD. Patients with an FVC of <80% had an increased risk of death versus patients with FVC ≥80% (HR, 1.72; 1.05-2.83). Furthermore, obese patients with ILD had an elevated risk of death (HR, 2.27; 1.39-3.71).Conclusions: Patients with ILD are at increased risk of death from COVID-19, particularly those with poor lung function and obesity. Stringent precautions should be taken to avoid COVID-19 in patients with ILD.

Identifying causation in hypersensitivity pneumonitis: a British perspective.

Background: Establishing whether patients are exposed to a 'known cause' is a key element in both the diagnostic assessment and the subsequent management of hypersensitivity pneumonitis (HP). Objective: This study surveyed British interstitial lung disease (ILD) specialists to document current practice and opinion in relation to establishing causation in HP. Methods: British ILD consultants (pulmonologists) were invited by email to take part in a structured questionnaire survey, to provide estimates of demographic data relating to their service and to rate their level of agreement with a series of statements. A priori 'consensus agreement' was defined as at least 70% of participants replying that they 'Strongly agree' or 'Tend to agree'. Results: 54 consultants took part in the survey from 27 ILD multidisciplinary teams. Participants estimated that 20% of the patients in their ILD service have HP, and of these, a cause is identifiable in 32% of cases. For patients with confirmed HP, an estimated 40% have had a bronchoalveolar lavage for differential cell counts, and 10% a surgical biopsy. Consensus agreement was reached for 25 of 33 statements relating to causation and either the assessment of unexplained ILD or management of confirmed HP. Conclusions: This survey has demonstrated that although there is a degree of variation in the diagnostic approach for patients with suspected HP in Britain, there is consensus opinion for some key areas of practice. There are several factors in clinical practice that currently act as potential barriers to identifying the cause for British HP patients.

Epidemiology of silicosis: reports from the SWORD scheme in the UK from 1996 to 2017.

OBJECTIVE: To document the demographic risk factors of workers reported to have silicosis in the UK. METHODS: All cases of silicosis reported to the Surveillance of Work-related and Occupational Respiratory Disease (SWORD) scheme between January 1996 and December 2017 were classified into one of eight industry categories, and one of five age groups. In addition, to investigate whether there had been any temporal change, mean age and range at diagnosis was plotted for each year. From 2006, data were also available relating to the date of onset of symptoms, allowing a comparison between workers with and without respiratory symptoms. RESULTS: For the period between 1996 and 2017, there were 216 cases of silicosis reported. The mean (range) age of those reported was 61 years (23-89), with the majority (98%) being male. Across all industries, 65% of cases were diagnosed in individuals of working age (<65 for men and <60 for women). Silicosis was reported in young workers across all industry groups, with around one in six of all silicosis cases affecting workers under the age of 46 years. There was no clear trend in age of diagnosis with time. Between 2006 and 2017, 81% of 108 workers with silicosis were reported to be symptomatic. CONCLUSIONS: Silicosis remains an important health problem in the UK affecting workers of all ages across a wide range of industries traditionally associated with silica exposure.

Metal worker's lung: spatial association with Mycobacterium avium.

BACKGROUND: Outbreaks of hypersensitivity pneumonitis (HP) are not uncommon in workplaces where metal working fluid (MWF) is used to facilitate metal turning. Inhalation of microbe-contaminated MWF has been assumed to be the cause, but previous investigations have failed to establish a spatial relationship between a contaminated source and an outbreak. OBJECTIVES: After an outbreak of five cases of HP in a UK factory, we carried out blinded, molecular-based microbiological investigation of MWF samples in order to identify potential links between specific microbial taxa and machines in the outbreak zone. METHODS: Custom-quantitative PCR assays, microscopy and phylogenetic analyses were performed on blinded MWF samples to quantify microbial burden and identify potential aetiological agents of HP in metal workers. MEASUREMENTS AND MAIN RESULTS: MWF from machines fed by a central sump, but not those with an isolated supply, was contaminated by mycobacteria. The factory sump and a single linked machine at the centre of the outbreak zone, known to be the workstation of the index cases, had very high levels of detectable organisms. Phylogenetic placement of mycobacterial taxonomic marker genes generated from these samples indicated that the contaminating organisms were closely related to Mycobacterium avium. CONCLUSIONS: We describe, for the first time, a close spatial relationship between the abundance of a mycobacterium-like organism, most probably M. avium, and a localised outbreak of MWF-associated HP. The further development of sequence-based analytic techniques should assist in the prevention of this important occupational disease.

Managing Asbestos-Containing Materials in the Built Environment: Report of a Health and Safety Executive and Government Office for Science Workshop.

The duty to manage asbestos in non-domestic premises is described in the Control of Asbestos Regulations 2012. Health and Safety Executive (HSE) policy and guidance on asbestos in the built environment in Great Britain is that asbestos-containing materials (ACMs) that are in good condition and unlikely to be disturbed can be managed in place. Where ACMs are in poor condition or likely to be disturbed they should be repaired, encapsulated or, if necessary, removed. HSE and Government Office for Science hosted a stakeholder workshop to consider evidence on the management of ACMs in public buildings. Invitees attended from a range of backgrounds (including regulatory, government, academic, medical, public interest groups, and professional service providers). Participants considered the evidence, suggested nine evidence gap areas and ranked these according to preference in an anonymous vote. The top three suggested evidence gaps were: (i) the comparative risks of managing ACMs in place versus removal; (ii) improved measurement techniques at lower fibre concentrations; and (iii) building the evidence base on the effectiveness of asbestos management and safe removal. HSE will use the workshop outputs to inform its research planning. It is anticipated that a number of initiatives for shared research will be explored.

Diagnosis and management of myasthenia gravis.

Myasthenia gravis is a rare long-term neurological condition that is characterised by fluctuating skeletal muscle weakness and fatigue, as well as respiratory difficulties. It is both an acquired autoimmune disease and a chronic neuromuscular disorder. Because of its rarity, myasthenia gravis is relatively unknown and may be unfamiliar to many nurses. While there are various types of myasthenia, this article focuses on myasthenia gravis, exploring its symptoms, diagnosis and treatment, and examining the nurse's role in managing the condition. The symptoms of myasthenic crisis and cholinergic crisis are also explained, and the experience of patients with myasthenia gravis in hospital and community settings is illustrated using case studies.
