In this report of a series of almost 2,800 patients reported to the Western Australian Mesothelioma Registry (WAMR) with mesothelioma over a period of 60 years, changes in exposure and survival can be seen over time. In particular, median survival has more than doubled from 156 days in 1960-1979 to 360 days in 2010-2020. Most men with mesothelioma worked in building or construction (31%). Do-it-yourself (DIY) & home renovation activities are the largest identified source of asbestos exposure in women with mesothelioma in this registry, accounting for 22% of cases. Thankfully, the data appears to show a reduction in incident rate ratio for DIY home renovation cases since a peak in 2005-2009.
Comment by Dr Mark Lavercombe:
This study explores the characteristics of engineered stone dust by analysis of fifty types of resin-based engineered stone, three natural stones and two non-resin-based building materials for their crystalline silica, metals and resin content. The investigators exposed human alveolar epithelial cells and macrophages to dust samples, and linear regression was performed to determine association between stone components and cellular response. The results suggest that crystalline silica content only partially explains macrophage toxicity, suggesting concern about the content of reduced-silica engineered stone products might be warranted.
Comment by Dr Mark Lavercombe:
Indwelling pleural catheters (IPCs) have become part of the standard of care of malignant pleural effusions, although concerns about potential for IPC-related infections persist. Inspired by guidelines for the management of peritoneal dialysis catheters recommending topical mupirocin application at the catheter site, this study explores whether IPCs are affected by the application of topical mupirocin, and whether this is feasible as part of IPC care. In seven IPCs treated with mupirocin, no concerning structural changes were observed in up to six months of observation. Mupirocin application in patients with IPCs was tolerated well. Further studies to evaluate efficacy in preventing infection will be required.
Comment by Dr Mark Lavercombe:
The researchers in this fascinating study induced dyspnoea using thoracoabdominal loading in 32 healthy adults without respiratory disease and with normal body mass index. High-flow nasal cannulae were used to administer either FiO2 21% or 100%. Visual analogue ratings of dyspnoea were completed, and showed both high-flow therapies were associated with reduction in symptoms, with no difference between FiO2 21% or 100%. There were also reductions in patient reported chest tightness and work/effort sensations. The authors hypothesise that the mechanism was reduction in afferent-reafferent mismatch. Further studies in patients with respiratory disease are recommended.
Comment by Dr Mark Lavercombe:
Management of patients with severe asthma has dramatically changed in recent decades, and the use of anti-interleukin-5 monoclonal antibodies is recommended in patients with a history of exacerbations and elevated serum eosinophils. In this prospective study, the authors evaluate outcomes for two agents in patients from severe asthma clinics at two tertiary centres between January 2017 and July 2020. Both mepolizumab and benralizumab demonstrated improved Asthma Control Questionnaire scores, increase in forced expiratory volume in one second, reduction in exacerbation frequency and reduction in oral corticosteroid use. Benralizumab appears superior in terms of reduction in exacerbations and increase in FEV1 when compared with mepolizumab, while they had similar rates of non-response and adverse effects.
Comment by Dr Mark Lavercombe:
In this analysis of almost 50,000 patients with idiopathic pulmonary fibrosis from the TriNetX US Collaborative Network, the authors defined subgroups based on self-identified race and ethnicity. The results demonstrate a significantly lower rate of anti-fibrotic use in patients who identified as Black when compared with White (6.2% vs 11.4%, p <0.0001), Hispanic (10.8% vs. 20.2%, p <0.0001) and Asian (9.6% vs. 14.7%, p = 0.0006). Hispanic patients had higher usage of anti-fibrotics than Asian patients (21.1% vs. 16.3%, p = 0.012), and no other comparisons were significant. Sub-group analysis for patients over 65 or with lower FVC demonstrated a persistent difference between treatment in Black and White cohorts. These data suggest that patients identifying as Black in the United States are significantly less likely to be treated with anti-fibrotic therapies for IPF and further data is required to determine why.
Comment by Dr Mark Lavercombe:
This pilot study explores the use of a ketogenic diet in the management of patients with suspected obesity hypoventilation syndrome (OHS). Two weeks of high-fat, low-carbohydrate diet was associated with a reduction in PvCO2 of 3 mmHg; those with PvCO2 > 50 mmHg at baseline achieved a reduction in PvCO2 of 6.4 mmHg. The researchers intend further research using arterial blood gas sampling and a more robust diagnosis of OHS in order to further evaluate a possible role for a ketogenic diet in OHS management.
Comment by Dr Mark Lavercombe:
In this retrospective cohort study, physicians at the Royal Brompton Hospital National Pulmonary Hypertension Service report on data collected over 21 years including 128 patients with interstitial lung disease with pulmonary hypertension. Included patients were required to have had right heart catheter study, pulmonary function testing and transthoracic echocardiogram. Patients with connective tissue diseases and other causes of pulmonary hypertension were excluded. In patients treated with PDE5 inhibitors, there was a significant improvement in overall survival independent of other prognostic markers, and this was most striking in those with normal right ventricular function at baseline.
Comment by Dr Mark Lavercombe:
This excellent review article collates the literature on IgG4-related disease and particularly its thoracic manifestations. The authors provide an overview of the pathogenesis which remains poorly understood, as well as the clinical and imaging features and a diagnostic algorithm. The identification of a paravertebral soft band on CT chest is relatively specific, while histology will vary depending on the type of tissue sampled. Corticosteroids and rituximab are shown to be effective therapies, although relapse can occur.
Comment by Dr Mark Lavercombe:
In this randomised controlled trial of a forty-minute behavioural intervention once weekly for eight weeks in stable adult asthma patients, the authors report significant improvement in both asthma- and sleep-related outcomes. The intervention group achieved a substantial increase in their activity levels when compared with controls, with increases in daily step counts and the amount of moderate to vigorous physical activity per week, and reduction in sedentary time. Sleep efficiency and asthma control also improved. exposure to inhaled PM2.5 particles and lung adenocarcinoma is demonstrated, with increased levels of exposure associated with increased malignancy risk. Given the low rate of smoking in adult women in Taiwan (<5%), this data suggests another possible contributor to the development of adenocarcinoma in non-smoking women.
Comment by Dr Mark Lavercombe:
This fascinating paper reports the result of bedside ultrasonographic evaluation of both ipsilateral and contralateral diaphragmatic function in patients presenting with unilateral pleural effusion, before and after pleurocentesis. Contralateral hemidiaphragmatic excursion increased in inverse proportion to ipsilateral hemidiaphragmatic excursion, with subsequent normalisation on both sides after drainage. Improvement in ipsilateral excursion correlated with improvement in dyspnoea. These novel findings suggest the need for further study of ventilatory drive and the mechanics of both hemidiaphragms in the setting of pleural effusion, and their association with dyspnoea.
Comment by Dr Mark Lavercombe:
Caring for a patient with chronic medical conditions can be a significant burden for caregivers, and this study examines the degree and nature of those burdens in carers of patients with severe asthma and COPD. Although limited by its relatively homogeneous sample, the authors present important data that illustrate the physical and psychosocial impacts on caregivers. Further, the similarity between the impacts of caregiving in severe asthma when compared with carers of COPD patients suggests a potential unmet need for carers of severe asthma patients.

Comment by Dr Mark Lavercombe:
Chronic cough presents a difficult diagnostic and management challenge, despite best practice guidelines and multidisciplinary treating teams. In this paper, the authors report on a cohort of patients presenting for mannitol bronchoprovocation testing for a variety of indications. Using the result of the mannitol challenge, cough frequency during testing and responses to the Newcastle.
Comment by Dr Mark Lavercombe:
This systematic review and meta-analysis examines the impact of early life exposures to risk factors and the subsequent development of COPD as an adult. Using 30 studies with almost 800 000 participants, the authors find significant associations between childhood serious respiratory infections, pneumonia and bronchitis, asthma, maternal smoking, low birth weight and childhood maltreatment. This study suggests a potential role for addressing these exposures in children for COPD prevention.
Comment by Dr Mark Lavercombe:
Many will have suspected that infections other than with the SARS-CoV-2 virus would have reduced during periods of strict contact restrictions, and this paper from New Zealand confirms reductions in infective respiratory admissions, including pneumonia, COPD and asthma during Winter of 2020. Non-infective respiratory diagnoses such as lung cancer, pulmonary embolism and pneumothorax did not decline. Although observational, these data suggest support for measures such as self-isolation when symptomatic with viral respiratory tract infections.
Comment by Dr Mark Lavercombe:
The authors of this paper illustrate the use of the forced oscillation technique to evaluate lung mechanics in people exposed to PM2.5 particulate matter after a fire in an open-cut brown coal mine in Hazelwood, Australia. Comparison with local residents who were not exposed to the same air pollution demonstrates more negative respiratory system reactance.
Comment by Dr Mark Lavercombe:
Frailty is an increasingly recognised prognostic marker in many conditions. Assessment for frailty using a simple five-point scale in this cohort of patients with fibrotic interstitial lung diseases demonstrates that frailty is common and associated with higher mortality, even after adjusting for ILD-GAP score. The authors suggest that frailty is potentially modifiable with pulmonary rehabilitation, although this will require further research.
Comment by Dr Mark Lavercombe:
The issues of procedural training and assessment of competence are subject to significant debate with a variety of approaches described. In this paper, the authors demonstrate a significant difference in performance measured using the Bronchoscopy Skills and Tasks Assessment Tool (BSTAT) and several other measures, after a 3-month structured curriculum including weekly simulation and direct supervision. Further work is needed to demonstrate a link to diagnostic yield and patient complications.
Comment by Dr Mark Lavercombe:
In this paper, the authors apply a retrospective target trial emulation on a large dataset of patients with sarcoidosis from Sweden, to examine the difference in infection rates between those treated with methotrexate and azathioprine for their steroid-sparing effect. Their findings suggest an initial reduction in relative infection risk in those treated with methotrexate, although the difference reduced over time. Prospective data is needed to confirm this finding.
Comment by Dr Mark Lavercombe:
In this large study of over 100,000 patients in the Korea NHIS, the association between a diagnosis of IPF and malignancy is explored. Overall cancer risk is confirmed to be higher (HR-2), largely driven by a significant excess in lung cancer diagnoses (HR-6).
Comment by Dr Mark Lavercombe:
This authors describe the functions of a multidisciplinary ILD clinic at a tertiary referral centre, expanding on the accepted role in multidisciplinary diagnosis to provide ongoing access to specialist physicians, nurses and physiotherapists in one setting. The patient perspective is provided by the use of instructive quotes from patient survey responses.
Comment by Dr Mark Lavercombe:
This study demonstrates that patients with an eventual diagnosis of interstitial lung disease will utilise more healthcare resources in the years leading to their ILD diagnosis, perhaps suggesting that earlier diagnosis is possible. Recognition of potential ILD can have an important impact on appropriate referral, diagnosis and management options, especially when considering agents that affect disease progression in IPF, or specific treatments for ILD associated with other conditions like CTD.
Comment by Dr Mark Lavercombe:
The rapid escalation in 'vaping' using electronic nicotine delivery devices has not yet been matched by data demonstrating their safety. In a cohort of asthmatic patients taking regular inhaled corticosteroids, acute markers of airway inflammation and pulmonary function changed within five minutes of e-cigarette vaping and this did not occur in healthy controls. The authors discuss the implications for future research in both healthy subjects and patients with pre-existing obstructive lung diseases.
Comment by Dr Mark Lavercombe:
The association between obstructive sleep apnoea and cardiovascular disease is well recognised. In this paper, the authors explore the role of comorbid elevation of the periodic limb movements in sleep index in a cohort of of patients with obstructive sleep apnoea, and demonstrate a significant elevation in systolic blood pressure, even after accounting for the degree of OSA with multivariate analysis. Further studies - including those utilising 24h BP monitoring - are recommended.
Comment by Dr Mark Lavercombe:
While the cause of the outbreak of e-cigarette, or vaping, product use associated lung injury (EVALI) in the United States remains under investigation, the broader issue of the long-term safety of vaping remains contentious. This paper contributes to the literature demonstrating abnormalities of human bronchial epithelial cell function associated with e-cigarette use. Further investigation and long-term data will be required.
Comment by Dr Mark Lavercombe:
In a cohort of 81 patients presenting with silicosis to a single centre in China, artificial stone exposure is associated with shorter latency to disease onset, and more rapid radiologic progression and reduction in lung function, when compared with those exposed to natural stone. This paper further contributes to the data surrounding accelerated silicosis in workers exposed to artificial stone that has been noted in multiple countries in recent years.
Comment by Dr Mark Lavercombe:
Differentiation of the causes of pulmonary hypertension has become more important with targeted treatments available that can change prognosis. This study demonstrates the potential utility of a simple non-invasive test to differentiate between PH and non-PH, and CTEPH and PAH. Further studies will be required to clarify test performance in other patient groups and to exclude confounders.
Comment by Dr Mark Lavercombe:
Non-expansile lung is considered a contraindication to talc slurry pleurodesis in malignant pleural effusion, however inter-observer agreement for diagnosing non-expansile lung on chest radiography is unknown. This study demonstrates poor correlation between experienced observers. Implications for study design and clinical treatment choices are considered.
Comment by Dr Mark Lavercombe:
In this nationwide study of 83425 patients with COPD, of whom 2637 had one or more acute coronary syndrome events during follow-up, low rates of beta-blocker prescription is found. This finding is especially pronounced in those with very severe COPD despite international guidelines recommending the use of beta-blockers in patients with coronary ischaemia and COPD.
Comment by Dr Mark Lavercombe:
In this study the authors demonstrate associations between sputum bacterial community characteristics and both structural and clinical measures in patients with bronchiectasis. Increase in blood inflammatory markers levels correlated with lower bacterial diversity, while reduced bacterial diversity, richness and evenness were associated with structural abnormalities on HRCT. The authors suggest a potential role for pathogenic bacterial dominance contributing to disease state.
Comment by Dr Mark Lavercombe:
Multiple studies have demonstrated an increase in cardiovascular outcomes in patients with COPD, and treatment with cardiac medications in patients with AECOPD has also been investigated. This large study demonstrates that adverse cardiac outcomes are markedly increased in patients with AECOPD, and especially in those who require hospitalisation.
Comment by Dr Mark Lavercombe:
Two papers published in Respirology Issue 24.11 (November 2019) consider the role of Nasal High Flow (NHF) therapy in patients with COPD. In this paper, NHF is compared with NIV (untitrated) in stable COPD patients with chronic hypercapnic respiratory failure. Patients found NHF easier to use and more comfortable, although NIV had more marginally more effect on PtCO2 levels.
Comment by Dr Mark Lavercombe:
Two papers published in Respirology Issue 24.11 (November 2019) consider the role of Nasal High Flow (NHF) therapy in patients with COPD. In this paper, addition of NHF with air (or oxygen for those requiring LTOT) during high intensity exercise did not improve endurance during pulmonary rehabilitation. Several potential explanations for discordance with prior studies are considered.
Comment by Dr Mark Lavercombe:
Selection of inhaler device is known to affect compliance in asthma patients. This study demonstrates that changing from one format to another can lead to significant improvement in outcomes and is generally accepted by the patients.
Comment by Dr Mark Lavercombe:
In a large cohort of patients admitted for acute exacerbation of chronic respiratory disease, the authors demonstrate low overall physical activity levels during the inpatient period with no significant improvement over time. This study also demonstrates little day-to-day variance, potentially allowing future study designs to benefit from shorter activity monitoring periods.
Comment by Dr Mark Lavercombe:
A simple tool to measure chronic cough and its impact on daily life can be useful for ongoing outpatient or clinic assessment of patients with this condition. In this paper, the authors develop and validate a 5-point questionnaire that correlates well with other tools and demonstrates reliability and validity in a Republic of Korean population.
Comment by Dr Mark Lavercombe:
This cohort study demonstrates the difficulty of differentiating sarcoidosis and tuberculosis. The diagnosis of tuberculosis within one year of sarcoidosis diagnosis occurred at a significant rate, suggesting the possibility of misdiagnosis. Further, subsequent diagnosis of sarcoidosis in patients treated for tuberculosis is significant after the first year of follow-up.
Comment by Dr Mark Lavercombe:
This study evaluates the effect of high-intensity inspiratory muscle training in patients with non-cystic fibrosis bronchiectasis. Two of the three weekly sessions were performed in the patients' homes using a threshold loading device. Improvements in shuttle walk distance and respiratory muscle strength and endurance are noted, along with the social dimension of quality of life. Treatment was well tolerated.
Comment by Dr Mark Lavercombe:
The authors of this paper publish the first data for a multi-ethnic Asian cohort of patients with pulmonary arterial hypertension and have follow-up to 14 years. The REVEAL risk score for prediction of one-year mortality is evaluated with a cut off of >6 found to have a hazard ratio for earlier death of 4.4.
Comment by Dr Mark Lavercombe:
Although malignant pleural effusion can be treated with repeated thoracenteses, identification of patients more likely to suffer recurrence of their effusion might lead to earlier definitive intervention. The authors identify several risk factors for recurrence in their cohort, however further study is required to develop a predictive model with external validity.
Comment by Dr Mark Lavercombe:
This population study examines the incidence of active tuberculosis diagnosis in a large population of patients with Type 2 Diabetes Mellitus. The authors demonstrate a significant protective effect in patients taking metformin, that is not seen with the use of other treatments including oral agents and insulin (despite improved glycaemic control). This suggests protection not only by improved glycaemic control but perhaps also via immune functions of metformin itself.
Comment by Dr Mark Lavercombe:
The authors review two years of data from their Malaysian hospital for correlation between respiratory admissions and local haze conditions. The findings demonstrate significantly increased rates of admission with respiratory symptoms during a haze, particularly in those with chronic lung or cardiac disease, and those with obesity. Length of stay and requirement for intensive care also increased in the haze periods.
Comment by Dr Mark Lavercombe:
This paper describes the findings of a retrospective review of 367 patients from a single centre who presented with pulmonary embolism. Pulmonary infarction was associated with younger age, absence of cardiopulmonary disease, presence of pleuritic chest pain and presence of an ipsilateral pleural effusion. Explanations based on pulmonary blood flow physiology and the development of collateral supply are proposed.
Comment by Dr Mark Lavercombe:
This intriguing study suggests the use of serum SA100A12 concentration as a prognostic marker in pulmonary hypertension. Despite relatively small sample sizes, elevated S100A12 levels were significantly associated with a diagnosis of PH, and negatively correlated to cardiac output. Increased overall mortality was associated with S100A12 levels in both discovery and validation cohorts.
Comment by Dr Mark Lavercombe:
The use of transthoracic echocardiography as a screening tool for pulmonary hypertension in patients with interstitial lung disease is explored in this study, which finds significant numbers of patients are misclassified based on TTE parameters. The possibility of a combined risk assessment using other clinical factors is suggested.
Comment by Dr Mark Lavercombe:
In this study, the authors seek to define the risks of pulmonary hypertension in patients with combined pulmonary fibrosis and emphysema compared with those with IPF alone. Their conclusion that CPFE is "not greater than the sum of its parts" helps guide prognostication in this patient cohort.
Comment by Dr Mark Lavercombe:
Clinicians have long relied on extrapolation of data from COPD studies to inform decision making around oxygen supplementation in patients with other chronic lung diseases. This study demonstrates a difference between patients with fibrotic ILDs and COPD in the degree of exertional oxygen desaturation, raising important questions about the appropriateness of extrapolation.
Comment by Dr Mark Lavercombe:
This paper describes the radiological follow-up of patients treated for cryptogenic organising pneumonia and demonstrates a high proportion of patients have residual radiologic abnormality. Several factors associated with persisting abnormalities are identified, including extent of consolidation and treatment duration.
Comment by Dr Mark Lavercombe:
This paper outlines the clinical and pathophysiologic features of the unexpandable lung. The authors demonstrate a clear distinction between chronic 'trapped lung' and the 'lung entrapment' that occurs in active pleural disease states such as malignancy or infection.
Comment by Dr Mark Lavercombe:
The authors of this paper describe a cohort of patients with COPD who were stratified based on self-report of prior history of tuberculosis infection. Patients who admitted to prior Tb had more severe symptoms of COPD, poorer lung function and more frequent exacerbations. This difference was noted despite a lower prevalence of ongoing smoking in the tuberculosis group.
Comment by Dr Mark Lavercombe:
Vocal cord dysfunction is not uncommon in patients after lung cancer resection, and this study demonstrates a significant association with poor post-operative outcomes including pneumonia, need for bronchoscopy and re-intubation. The authors recommend routine laryngeal screening within 24h of surgery, although treatment outcomes were not assessed in this study.
Comment by Dr Mark Lavercombe:
The authors of this paper describe the natural history of single and multiple ground glass nodules (GGN) over a 36 month period. They demonstrate that partly solid and ≥ 10mm size solitary GGN are more likely to progress, while ≥ 10 mm and past history of lung cancer were associated with progression in multiple GGN.
Comment by Dr Mark Lavercombe:
Using data from the China National Health Survey 2012–2015, the authors of this paper propose spirometry prediction equations for a general Chinese population aged 7–80 years. Their equations compare favourably to those developed in more heterogeneous cohorts.
Comment by Dr Mark Lavercombe:
EBUS-TBNA has rapidly become the standard of care for mediastinal and hilr lymph node sampling. This systematic review outlines the range and frequency of potential complications, as well as the possibility that these reports do not represent the full scale of adverse outcomes.
Comment by Dr Mark Lavercombe:
This important study demonstrates that patients with concomitant diabetes mellitus have different clinical features at diagnosis of tuberculosis, higher risk of adverse effects on treatment, slower sputum conversion, and lower treatment success at twelve months. Further data on the effect of diabetic control in patients treated for tuberculosis is required.
Comment by Dr Mark Lavercombe:
The authors of this paper outline the use of EBUS elastography for both qualitative and quantitative assessment of mediastinal lymphadenopathy for the presence of malignancy. Their promising findings suggest the need for further study to better define the elastographic features in both benign and malignant conditions, in order to guide the need for TBNA sampling.
Comment by Dr Mark Lavercombe:
This paper demonstrates a significant relationship between levels of cardiac troponin measured at admission in patients with Community-Acquired Pneumonia and both 30-day and long-term mortality. The combination of Pneumonia Severity Index with Troponin level predicted mortality better than either model alone. These findings suggest cardiac evaluation might be worthwhile in patients with CAP and elevated Troponin.
Despite the clear health benefits in COPD patients, participation in pulmonary rehabilitation is variable with potential barriers including reduced mobility, lack of transport or travel costs. This randomised controlled trial evaluates home-based telerehabilitation compared with usual care and finds improved endurance exercise capacity and self-efficacy in the treatment group. Telerehabilitation might be an alternative option for pulmonary rehabilitation in those unable to attend centralised programmes. Table 3 presents outcomes for special consideration.

This Executive Summary focuses primarily on the revised and novel parts of the document, including:
Comment by Dr Mark Lavercombe:
This important study describes a large cohort of patients admitted with acute pulmonary embolism to Intensive Care Units across Australia and New Zealand. A subpopulation at very high risk of death is identified (those requiring mechanical ventilation). No improvement in mortality rate over time is seen.
Comment by Dr Mark Lavercombe:
The indications for thoracic ultrasonography continue to expand, and this study suggests another indication. Diaphragmatic dysfunction found on ultrasound on admission in patients with acute hypercapnic exacerbations of COPD is identified as a risk factor for failure of NIV, duration of mechanical ventilation and short-term mortality. This non-invasive test might help clinicians identify patients at risk of failing standard care.
Comment by Dr Mark Lavercombe:
This study examines the utility of bronchoscopy in patients admitted with acute exacerbations of interstitial lung disease. Although a relatively low diagnostic yield is identified, significant potential complications are noted and there is no in-hospital mortality benefit seen in those undergoing the procedure.
Comment by Dr Mark Lavercombe:
This study identifies important risk factors for mortality in Asian patients with COPD, and develops a prognosis model that is easy to use. Further validation studies will be required to assess its utility.
Comment by Dr Mark Lavercombe:
This original article suggests that malignant pleural effusion in mesothelioma might not be purely a consequence of the malignancy, but could contribute to its pathobiology. This suggests the possibility of future therapeutic targets in this disease.
Comment by Dr Mark Lavercombe:
This study demonstrates that assessment of the diagnosis and management of interstitial lung diseases by an expert multidisciplinary panel can potentially make a major contribution to patient outcomes. A significant proportion of patients is re-classified after MDT discussion, leading to changes in management. Longer term follow-up of patient outcomes might add weight to the use of MDT discussions.
Comment by Dr Mark Lavercombe:
This systematic review identifies regional variations in the underlying aetiologies for non-CF bronchiectasis, which is important to consider when evaluating the applicability of the bronchiectasis literature. It also provides an evidence base for the clinical workup of these patients leading to a change in management.
