Background Opioids are often required for acute inpatient pain relief but lack of knowledge about common and less common long-term side effects can lead to inappropriate discharge prescribing. There are few validated educational tools available for junior prescribers on hospital wards. Education around opioid prescribing and deprescribing remains limited in the undergraduate curriculum and yet almost all controlled drug prescribing in hospitals is done by junior doctors. Methods A 5-minute video was developed with iterative feedback from medical students, junior prescribers, pain specialists, primary care educational leads, and a patient who had developed opioid addiction after hospital prescribing. It explained the need for clear stop dates on discharge summaries and the range of opioid side effects. It also highlighted the hospital admission as an opportunity to reduce inappropriate high-dose opioids. A short knowledge-based quiz before and after viewing the video was used to evaluate the impact on and change in knowledge and confidence around opioid prescribing. This tool was designed to be used entirely online to allow delivery within existing mandatory training. Results Feedback was positive and showed that knowledge of side effects significantly increased but also contacts with ward pharmacists and the acute pain team increased. Junior doctors highlighted that the undergraduate curriculum did little to prepare them for prescription addiction and that pharmacy and senior support was needed to support any changes in longer-term, high-dose opioids. Conclusions This short educational video improved knowledge of safe opioid prescribing and could be incorporated within wider opioid education in UK healthcare.

The recovery paradigm in the context of serious mental illnesses pertains to several characteristics of community functioning, adjustment, and integration, among other constructs. Additional rating scales would be beneficial for measuring various facets of community functioning for research that is recovery oriented as opposed to symptom focused. The Community Navigation Scale was developed as part of the Opening Doors to Recovery project to address several aspects of navigating community resources.After item development, the 21-item Community Navigation Scale was used across two studies with 340 participants who had serious mental illnesses. Factor analysis revealed three potential factors, and subscales were computed.The social and physical well-being subscale (seven items, Cronbach's α=0.82) addressed community involvement, volunteering, finding enjoyable activities, and engaging in positive health behaviors. The accessing external resources subscale (nine items, Cronbach's α=0.80) tapped one's ability to obtain needed resources, ranging from medications to housing and from small appliances to classes in the community. The home and self-maintenance subscale (five items, Cronbach's α=0.73) measured abilities around shopping, cooking, cell phone use, house cleaning, and personal grooming and hygiene. Initial validity of the subscales was suggested through correlations with the Multnomah Community Ability Scale (r=0.65, 0.55, and 0.41 for social and physical well-being, accessing external resources, and home and self-maintenance, respectively).The Community Navigation Scale assesses dimensions of community functioning among persons with serious mental illnesses and may add to the array of research and clinical measures pertinent to recovery outcomes. Additional research on its psychometric properties is warranted.

Individuals with serious mental illnesses are overrepresented in all facets of the legal system. State-level criminal histories of patients with serious mental illnesses were analyzed to determine the proportion who had been arrested and number of lifetime arrests and charges, associations of six variables with number of arrests, and the most common charges from individuals’ first two arrests and most recent two arrests.A total of 240 patients were recruited at three inpatient psychiatric facilities and gave consent to access their criminal history. Information was extracted from Record of Arrest and Prosecution (RAP) sheets for lifetime arrests in Georgia.A total of 171 (71%) had been arrested. Their mean±SD lifetime arrests were 8.6±10.1, and mean lifetime charges were 12.6±14.6. In a Poisson regression, number of arrests was associated with lower educational attainment, Black or African American race, the presence of a substance use disorder, the presence of a mood disorder, and female sex. Common early charges included marijuana possession, driving under the influence of alcohol, and burglary and shoplifting. Common recent charges included probation violations, failure to appear in court, officer obstruction–related charges, and disorderly conduct.Findings point to a need for policy and program development in the legal system (e.g., pertaining to charges such as willful obstruction of an officer), the mental health community (e.g., to ensure that professionals know about clients’ legal involvement and can partner in strategies to reduce arrests), and social services sectors (to address charges, such as shoplifting, often related to material disadvantage).

Prediction of disease course in patients with progressive pulmonary fibrosis remains challenging. The purpose of this study was to assess the prognostic value of lung fibrosis extent quantified at computed tomography (CT) using data-driven texture analysis (DTA) in a large cohort of well-characterized patients with idiopathic pulmonary fibrosis (IPF) enrolled in a national registry.This retrospective analysis included participants in the Australian IPF Registry with available CT between 2007 and 2016. CT scans were analysed using the DTA method to quantify the extent of lung fibrosis. Demographics, longitudinal pulmonary function and quantitative CT metrics were compared using descriptive statistics. Linear mixed models, and Cox analyses adjusted for age, gender, BMI, smoking history and treatment with anti-fibrotics were performed to assess the relationships between baseline DTA, pulmonary function metrics and outcomes.CT scans of 393 participants were analysed, 221 of which had available pulmonary function testing obtained within 90 days of CT. Linear mixed-effect modelling showed that baseline DTA score was significantly associated with annual rate of decline in forced vital capacity and diffusing capacity of carbon monoxide. In multivariable Cox proportional hazard models, greater extent of lung fibrosis was associated with poorer transplant-free survival (hazard ratio [HR] 1.20, p 0.0001) and progression-free survival (HR 1.14, p 0.0001).In a multi-centre observational registry of patients with IPF, the extent of fibrotic abnormality on baseline CT quantified using DTA is associated with outcomes independent of pulmonary function.

Initial radiologic appearance rather than management strategy predicts the outcomes of sleeve gastrectomy leaks.Multiple modalities have been advocated for the treatment of sleeve gastrectomy leak, and there remains no consensus on the best treatment paradigm. For more than 10 years, we have variably attempted luminal occlusive therapies and repeated endoscopic debridement as treatment options. By evaluating the outcomes from these approaches, we aimed to determine whether the first management strategy is superior to the second in terms of outcomes.Patients were analyzed by group (luminal occlusive therapy versus repeated endoscopic debridement). Leaks were then stratified by radiologic appearance on computed tomography, defined as phlegmon, collection, contrast medium leak, or fistula. The primary outcome was length of stay (LOS). Secondary outcomes were comprehensive complication index and the need for resection.There were 54 patients, with 22 in the luminal occlusion group and 32 in the repeated debridement group. There was no difference in LOS (59.8 ± 41.6 versus 46.5 ± 51.2 days, P = .179) and no difference in the requirement for resection (4 versus 3 resections, p = .425). Subset analysis suggested that patients who underwent operative versus conservative management (P = .006) had a longer LOS. Excluding management strategy, radiologic appearance on admission significantly predicted LOS (P = .0053). Patients presenting with fistula (84 ± 25.4 days) and contrast medium leak (64.1 ± 40 days) had a significantly longer LOS than those diagnosed with phlegmon (13.5 ± 5.5 days). Radiologic appearance was predictive of complication severity (P.0001) and salvage resection (P = .008).There was no significant difference in outcomes between patients treated with intraluminal occlusion or repeated debridement. Initial radiologic appearance was predictive of LOS and complication severity. This highlights the need for routine use of a validated classification system in studies reporting outcomes and treatment of sleeve leaks.

Background Chronic rhinosinusitis affects 62% of adults with bronchiectasis and is linked to greater bronchiectasis severity. However, the impact of symptoms of chronic rhinosinusitis on disease‐specific and cough‐related quality of life is unknown. Methods In this cross‐sectional study, adults with stable bronchiectasis and chronic rhinosinusitis symptoms completed the sinonasal outcome test‐22 (SNOT‐22), quality of life–bronchiectasis questionnaire, and Leicester cough questionnaire. Bronchiectasis severity was assessed using the bronchiectasis severity index (BSI) and chest high‐resolution computed tomography (HRCT). Results Sixty participants with bronchiectasis (mean [SD] forced expiratory volume in 1 s of 73.2 [25.5] %predicted) were included. Greater severity of chronic rhinosinusitis symptoms (based on SNOT‐22) was moderately associated with impaired cough‐related quality of life (according to the Leicester cough questionnaire; all r > −.60) and impaired bronchiectasis‐specific quality of life (based on the quality of life–bronchiectasis questionnaire), with impaired physical function (r = −.518), less vitality (r = −.631), reduced social function (r = −.546), greater treatment burden (r = −.411), and increased severity of respiratory symptoms (r = −.534). Chronic rhinosinusitis symptoms were unrelated to disease severity according to the BSI (r = .135) and HRCT scoring (all r

OBJECTIVES To develop and validate a classification of sleeve gastrectomy leaks able to reliably predict outcomes, from protocolized computed tomography (CT) findings and readily available variables. SUMMARY OF BACKGROUND DATA Leaks post sleeve gastrectomy remain morbid and resource-consuming. Incidence, treatments, and outcomes are variable, representing heterogeneity of the problem. A predictive tool available at presentation would aid management and predict outcomes. METHODS From a prospective database (2009-2018) we reviewed patients with staple line leaks. A Delphi process was undertaken on candidate variables (80-20). Correlations were performed to stratify 4 groupings based on outcomes (salvage resection, length of stay, and complications) and predictor variables. Training and validation cohorts were established by block randomization. RESULTS A 4-tiered classification was developed based on CT appearance and duration postsurgery. Interobserver agreement was high (κ=0.85, P

Background and objective Current guidelines for the diagnosis of idiopathic pulmonary fibrosis (IPF) provide specific criteria for diagnosis in the setting of multidisciplinary discussion (MDD). We evaluate the utility and reproducibility of these diagnostic guidelines, using clinical data from the Australian IPF Registry. Methods All patients enrolled in the registry undergo a diagnostic review whereby international IPF guidelines are applied via a registry MDD. We investigated the clinical applicability of these guidelines with regard to: (i) adherence to guidelines, (ii) Natural history of IPF diagnostic categories and (iii) Concordance for diagnostic features. Results A total of 417 participants (69% male, 70.6 ± 8.0 years) with a clinical diagnosis of IPF underwent MDD. The 23% of participants who did not meet IPF diagnostic criteria displayed identical disease behaviour to those with confirmed IPF. Honeycombing on radiology was associated with a worse prognosis and this translated into poorer prognosis in the ‘definite’ IPF group. While there was moderate agreement for IPF diagnostic categories, agreement for specific radiological features, other than honeycombing, was poor. Conclusion In clinical practice, physicians do not always follow IPF diagnostic guidelines. We demonstrate a cohort of IPF patients who do not meet IPF diagnostic guideline criteria, based largely on their radiology and lack of lung biopsy, but who have outcomes identical to those with IPF.

Purpose of Review Chronic wounds are a tremendous burden on the healthcare system and lead to significant patient morbidity and mortality. Normal cutaneous wound healing occurs through an intricate and delicate interplay between the immune system, keratinocytes, and dermal cells. Each cell type contributes signals that drive the normal phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This paper reviews how various immunological cell types and signaling molecules influence the way wounds develop, persist, and heal. Recent Findings Concurrent with the achievement of hemostasis, neutrophils are the first cells to migrate to the wound bed, brought in by pro-inflammatory signals including IL-8. Their apoptosis and engulfment by macrophages (efferocytosis) provides a key signal to the local immune milieu, including macrophages, to transition to an anti-inflammatory, pro-repair state, where angiogenesis occurs and granulation tissue is laid down. Myofibroblasts, activated through contractile forces and signaling molecules, then drive remodeling, where granulation tissue becomes scar. Unchecked inflammation at this stage can result in abnormal scar formation. Summary Although the derangement of immune signals at any stage can result in impaired wound healing, recent research has shown that the key transition point lies between the inflammatory and the proliferative phases. This review summarizes the events that facilitate this transition and discusses how this process can be disrupted, leading to chronic, non-healing wounds.

Background As medical schools strive to improve the learning environment, it is important to understand medical students' perceptions of mistreatment. The purpose of this study was to explore student interpretations of previously reported mistreatment incidents to better understand how they conceptualise the interactions. Methods Medical students were presented with case scenarios of previously reported instances of mistreatment and asked to indicate their agreement as to whether the scenarios demonstrated mistreatment, using a five-point Likert scale (1, strongly disagree; 5, strongly agree). It is important to understand medical student's perceptions of mistreatment RESULTS: One hundred and twenty-seven third-year medical students gave feedback on 21 mistreatment cases. There was variability in the categorisation of the scenarios as mistreatment. The highest degree of consensus (96% agreement) was for a scenario in which a resident claimed a student made statements about a patient's status that the student did not make. There was also relative consensus on three additional scenarios: (1) a patient making disparaging remarks about a student's role in health care in relation to the student's ethnicity (88% agreement); (2) a resident asking a student to run personal errands (86% agreement); and (3) a nurse calling a student an expletive in front of others (77% agreement). For the majority of the cases, there was no consensus amongst students as to whether mistreatment had occurred. Students self-identifying as minorities and students who had previously reported mistreatment were more likely to perceive mistreatment in the scenarios. Conclusions There is remarkable variability, and in many cases a lack of agreement, in medical student perceptions of mistreatment. This inconsistency needs to be considered in order to effectively address and mitigate the issue.

Background: Mycobacterium abscessus complex (MAbsC) is a significant management dilemma when taking care of patients with cystic fibrosis (CF). Methods: We undertook a retrospective cohort analysis of all CF patients in whom MAbsC was isolated from 2005 to 2014. The natural history of MAbsC was determined and clinical factors examined in an attempt to predict transient compared to persistent colonization. Results: No correlation was found between recurrent MAbsC isolation and clinical factors such as body mass index, respiratory function, or age. Over two-thirds of our cohort cleared MAbsC colonization with no intervention and no consistent effect on lung function was identified. Four CF patients were initiated on treatment with only one successful outcome. Conclusion: This analysis demonstrates there are no clear predictors of those CF patients who will become persistently colonized with MAbsC and that a significant proportion will spontaneously clear carriage. As treatment success rate is poor, more work is urgently required in improving patient outcomes.

BackgroundIdiopathic pulmonary fibrosis (IPF) is a progressive lung disease in which circulatory biomarkers have the potential for guiding management in clinical practice. We assessed the prognostic role of serum biomarkers in three independent IPF cohorts: Australian Idiopathic Pulmonary Fibrosis Registry (AIPFR), Trent Lung Fibrosis (TLF) and Prospective Observation of Fibrosis in the Lung Clinical Endpoints (PROFILE).MethodsIn the AIPFR cohort, candidate proteins were assessed by ELISA as well as in an unbiased proteomic approach. LASSO (least absolute shrinkage and selection operator) regression was used to restrict the selection of markers that best accounted for the progressor phenotype at 1 year in the AIPFR cohort, and subsequently prospectively selected for replication in the validation TLF cohort and assessed retrospectively in the PROFILE cohort. Four significantly replicating biomarkers were aggregated into a progression index model based on tertiles of circulating concentrations.Results189 participants were included in the AIPFR cohort, 205 participants from the TLF cohort and 122 participants from the PROFILE cohort. Differential biomarker expression was observed by ELISA and replicated for osteopontin, matrix metallopeptidase-7, intercellular adhesion molecule-1 and periostin for those with a progressor phenotype at 1 year. Proteomic data did not replicate. The progression index in the AIPFR, TLF and PROFILE cohorts predicted risk of progression, mortality and progression-free survival. A statistical model incorporating the progression index demonstrated the capacity to distinguish disease progression at 12 months, which was increased beyond the clinical GAP (gender, age and physiology) score model alone in all cohorts, and significantly so within the incidence-based TLF and PROFILE cohorts.ConclusionA panel of circulatory biomarkers can provide potentially valuable clinical assistance in the prognosis of IPF patients.

Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease associated with debilitating symptoms of dyspnoea and cough, resulting in respiratory failure, impaired quality of life and ultimately death. Diagnosing IPF can be challenging, as it often shares many features with other interstitial lung diseases. In this article, we summarise recent joint position statements on the diagnosis and management of IPF from the Thoracic Society of Australia and New Zealand and Lung Foundation Australia, specifically tailored for physicians across Australia and New Zealand. Main suggestions: A comprehensive multidisciplinary team meeting is suggested to establish a prompt and precise IPF diagnosis. Antifibrotic therapies should be considered to slow disease progression. However, enthusiasm should be tempered by the lack of evidence in many IPF subgroups, particularly the broader disease severity spectrum. Non-pharmacological interventions including pulmonary rehabilitation, supplemental oxygen, appropriate treatment of comorbidities and disease-related symptoms remain crucial to optimal management. Despite recent advances, IPF remains a fatal disease and suitable patients should be referred for lung transplantation assessment.

Interstitial lung diseases (ILD) are a diverse group of pulmonary diseases for which accurate diagnosis is critical for optimal treatment outcomes. Diagnosis of ILD can be challenging and a multidisciplinary approach is recommended in international guidelines. The purpose of this position paper is to review the evidence for the use of the multidisciplinary meeting (MDM) in ILD and suggest an approach to its governance and constitution, in an attempt to provide a standard methodology that could be applied across Australia and New Zealand. This position paper is endorsed by the Thoracic Society of Australia and New Zealand (TSANZ) and the Lung Foundation Australia (LFA).

Given fragmentation between mental health and criminal justice systems, we tested the feasibility of implementing a potential new form of pre-booking jail diversion. Our "linkage system" consists of three steps: (i) individuals with serious mental illnesses and an arrest history give special consent to be enrolled in a statewide database; (ii) if an officer has an encounter with an enrolled patient and runs a routine background check, he or she receives an electronic message to call; and (iii) the "linkage specialist" provides brief telephonic assistance to the officer. Of 206 eligible individuals, 199 (96.6%) opted in, the database received 679 hits, and the linkage specialist received 31 calls (and in at least three cases an arrest was probably averted). The mean number of arrests was 0.59 ± 0.92 in the year before enrollment (38.7% arrested) and 0.48 ± 0.83 during the 12-month intervention (30.7% arrested). Implementation is feasible, and a signal that the system might reduce incarceration was detected, encouraging development of a larger study.

Background and objective Studies analysing the effect of worsening pulmonary physiological impairment in idiopathic pulmonary fibrosis (IPF) with respect to quality of life have been limited to single centres or highly selected trial populations. The aim of this study was to determine the principal determinants of baseline and longitudinal health-related quality of life (HRQoL) in a large unselected IPF population. Methods We used the Australian IPF Registry to examine the relationship between HRQoL, measured using the St George Respiratory Questionnaire (SGRQ), and demographic features, physiological features, co-morbidities and symptoms. Linear regression analysis was performed to identify predictors of baseline HRQoL, linear mixed model analysis to determine the effect of time and forced vital capacity (FVC) on SGRQ and Cox proportional hazards regression to examine the relationship between HRQoL and all-cause mortality. Results Baseline data from 516 patients were available (347 males; mean (SD) age: 71.3 ± 8.6 years). Univariate analysis showed significant associations between HRQoL and demographic, clinical and physiological features. However, multivariate analysis demonstrated independent associations only between SGRQ and dyspnoea (University of California San Diego Shortness of Breathlessness Questionnaire (UCSD-SOBQ); R2 = 0.71, P

Idiopathic pulmonary fibrosis (IPF) is a chronic disease characterised by progressive decline in pulmonary function. The rate of decline can vary, with some patients remaining stable over longer periods of time and others rapidly progressing [1]. tThe variable progression of this disease makes it difficult to elucidate pathogenic pathways involved in the initiation and progression of IPF. Advances in high-throughput gene-expression analyses have led to improvements in our understanding of disease biology and prognostic gene signatures. We hypothesise that IPF has a unique circulatory transcriptional profile compared to healthy controls, with additional differences between stable and progressive disease likely related to disease pathogenesis.

Idiopathic pulmonary fibrosis (IPF) is a chronic disease characterised by an overall poor prognosis. The rate of disease decline and progression to death can vary, with some patients remaining stable over longer periods of time and others displaying rapid progression [1, 2]. The highly heterogeneous nature of this disease makes it difficult to elucidate the pathways involved in the initiation and progression of IPF and what determines the clinical trajectory of these patients. Advances in high-throughput gene expression analyses have led to improvements in our understanding of disease biology with insights into prognostic and predictive gene signatures [3]. This study sought to characterise differences in gene expression profiles found in the circulation between “stable” and “progressive” IPF patients, to help identify relevant biomarkers that may provide insights into the pathogenesis of progressive IPF.

Pancreatic haemangiomas are a rare cause of pancreatic lesions in adults. Diagnosis is challenging as they are seldom suspected and difficult to differentiate on imaging. Historically, pancreatic haemangiomas have been managed surgically despite their benign nature, largely due to diagnostic uncertainty. We present the case of a 69-year-old woman who, through combination of radiological, biochemical and endoscopic investigations, was diagnosed with pancreatic haemangioma and managed conservatively, avoiding the morbidity and mortality associated with surgical resection of a benign lesion.

Background and objective Multidisciplinary discussions (MDDs) have been shown to improve diagnostic accuracy in interstitial lung disease (ILD) diagnosis. However, their clinical impact on patient care has never been clearly demonstrated. We describe the effect that an ILD multidisciplinary service has upon the diagnosis and management of patients with suspected ILD. Methods Patients at two specialized centres with suspected ILD underwent ILD multidisciplinary team review (ILD-MDT) (standard ILD clinic visit and diagnostic review at ILD-MDD). We compared changes in ILD diagnosis and management at referral to those following the ILD-MDT. Results Ninety patients, 60% males (54/90), aged 67.3 years (SD = 11.4) were reviewed for suspected ILD. Overall, the ILD-MDT resulted in a change in specific ILD diagnosis in 48/90 (53%) patients. Of the 27 patients referred with a diagnosis of idiopathic pulmonary fibrosis (IPF), the diagnosis was changed at MDD in 10 patients. In contrast, seven patients had their diagnosis changed to IPF. There was also a significant reduction in ‘unclassifiable’ diseases and disease behaviour classifications provided additional information beyond ILD diagnosis. Conclusion Dedicated tertiary ILD-MDT service has an important clinical impact on the care of the ILD patient, with frequent changes in ILD diagnosis and subsequent management. Further research to investigate long-term clinical outcomes of ILD-MDT is required.

Mucormycosis carries a high mortality rate with few therapeutic options available. We describe a man with pulmonary/splenic mucormycosis complicating hypoplastic myelodysplastic syndrome on a background of chronic kidney disease, who achieved a complete response with salvage isavuconazole therapy following intolerance of consecutive courses of liposomal amphotericin and posaconazole therapy.

Subjective social status (SSS) and objective socioeconomic status (OSS) may appear to be similar social determinants of mental health, but are actually independently associated with diverse health outcomes including substance use and substance use disorders (SUDs). Such associations have not been examined among individuals with serious mental illnesses (SMI) despite their high prevalence of comorbid substance use; frequent treatment and recovery complications associated with such use; and high levels of economic disadvantage, discrimination, and inequities in this marginalized population. These psychosocial adversities manifest as poor mental illness outcomes, poor physical health, and early mortality in populations with SMI. We hypothesized that both SSS and OSS would predict substance use severity and SUD diagnoses in 240 patients with SMI. SSS, measured by the MacArthur Scale of Subjective Social Status, was unassociated with a composite measure of income and education used to operationalize OSS. Additionally, SSS and OSS were differentially associated with various types of substance use disorders. Only OSS was associated with whether individuals smoked cigarettes, or the level of nicotine dependence. Conversely, only SSS was associated with drug use severity. Our results shed light on the potential for differential impacts of SSS and OSS among persons with SMI.

Hope and empowerment are key elements of recovery in the context of serious mental illnesses (SMI). We examined predictors of hope among individuals with SMI and tested a hypothesized path model in which perceived social status and perceived discrimination adversely impact hope, directly and through their impacts on depressive symptoms. Data from 232 individuals with SMI receiving care in public-sector settings were used in both a multiple linear regression (predicting Herth Hope Scale scores), and in path analyses examining both direct and indirect effects of perceived social status (Social Status Ladder) and perceived discrimination (Everyday Discrimination Scale). Depressive symptoms, perceived social status, and perceived discrimination were predictive of hope. Path analyses revealed that perceived social status has a direct effect on hope and empowerment but also impacts hope through its effects on depression. Similarly, perceived everyday discrimination affects hope and empowerment, though this effect is mediated through its effects on depression. Two alternative models and a trimmed hypothesized model did not fit the data or improve fit. These social determinants of mental health should provoke program and policy change to improve mental health and enhance recovery among persons with SMI.

Serpulanines A (1), B (2), and C (3) have been isolated from extracts of the rare Sri Lankan macrofungus Serpula sp. The structures of 1, 2, and 3 were elucidated by a combination of spectroscopic and single-crystal X-ray diffraction analyses. Serpulanines A (1) and B (2) both contain the rare (E)-2-hydroxyimino hydroxamic acid functional group array. A proposed biogenesis for serpulanine B (2) suggests that its (E)-2-hydroxyimino hydroxamic acid moiety arises from a diketopiperazine precursor. Synthetic serpulanine A (1) inhibited class I/II histone deacetylases in murine metastatic lung carcinoma cells with an IC50 of 7 μM.

Background Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal fibrosing lung disease of unknown cause. The advent of anti-fibrotic medications known to slow disease progression has revolutionised IPF management in recent years. However, little is known about the natural history of IPF patients with mild physiological impairment. We aimed to assess the natural history of these patients using data from the Australian IPF Registry (AIPFR). Methods Using our cohort of real-world IPF patients, we compared FVC criteria for mild physiological impairment (FVC ≥ 80%) against other proposed criteria: DLco ≥ 55%; CPI ≤40 and GAP stage 1 with regards agreement in classification and relationship with disease outcomes. Within the mild cohort (FVC ≥ 80%), we also explored markers associated with poorer prognosis at 12 months. Results Of the 416 AIPFR patients (mean age 70.4 years, 70% male), 216 (52%) were classified as ‘mild’ using FVC ≥ 80%. There was only modest agreement between FVC and DLco (k = 0.30), with better agreement with GAP (k = 0.50) and CPI (k = 0.48). Patients who were mild had longer survival, regardless of how mild physiologic impairment was defined. There was, however, no difference in the annual decline in FVC% predicted between mild and moderate-severe groups (for all proposed criteria). For patients with mild impairment (n = 216, FVC ≥ 80%), the strongest predictor of outcomes at 12 months was oxygen desaturation on a 6 min walk test. Conclusion IPF patients with mild physiological impairment have better survival than patients with moderate-severe disease. Their overall rate of disease progression however, is comparable, suggesting that they are simply at different points in the natural history of IPF disease.

Introduction Idiopathic pulmonary fibrosis (IPF) is a progressive disease ultimately resulting in respiratory failure and death. While decline in FVC is often used as an endpoint in clinical trials, it is unclear whether this reflects longer term outcomes, especially given significant phenotypic heterogeneity of IPF. Methods Patients from the Australian IPF Registry with ≥ 2 lung function tests performed within 1 yr were included. Using regression modelling the trajectory of FVC %pred was obtained for each patient over 1yr. Patients were then categorised as: ‘decliners’ if annual slope change was ≥10% decline or ‘stable’. Baseline characteristics were compared and outcomes post 1 yr were assessed. Results 217 subjects (Age 70.2±8.2yrs, 74% male) with IPF were included: 148 stable; 69 decliners. Patients who declined had higher baseline FVC%pred (85.4% vs 79.1%; p= 0.034), but there was no other differences in demographics or other measures of lung function. There were 57 (26%) deaths recorded, with no difference found for mortality between the two groups using Cox analysis (p=0.376). There was also no difference in the post 1 yr annual FVC %pred decline using linear mixed models, with initial decliners falling 3.9% p.a. thereafter, while the initially stable patients fell 4.3% p.a. (p=0.827). The median post-first yr follow-up time was 1.1 yrs (IQR 0.64 to 1.88 yrs), amounting to a total of 280 patient years. Conclusion It is not possible to predict patient outcomes on the basis of the 1 yr decline in FVC. There is a need for improved biomarkers to predict disease behaviour in individual patients, and inform management decisions.

The most effective point of intervention to prevent unnecessary arrest/incarceration of persons with serious mental illnesses is the initial encounter with police. We piloted a new police-mental health linkage system. When officers run an enrolled participant's name/identifiers, they receive an electronic message that the person has mental health considerations and that they should call for information. The linkage specialist receives the call and assists telephonically. In this qualitative study to examine acceptability of the linkage system, we conducted nine focus groups with diverse stakeholders (e.g., enrolled patients, officers). Focus groups revealed that patients enrolled with the hope that the linkage system would prevent negative interactions with police and minimize risk of arrest. Officers reported preferring not to arrest mental health patients and were genuinely invested in helping them, and felt that the linkage system might be an additional tool during encounters. Findings revealed acceptability of the intervention, and further research is warranted.

There is little Australian epidemiologic data on idiopathic pulmonary fibrosis (IPF), a relatively uncommon but devastating disease. The vast geographic distances in Australia have been a major impediment for collaborative research into IPF. A collaborative national effort, the Australian IPF Registry, has been formed, launched and is recruiting successfully (n = 359, January 2014). Our experience provides unique insights for others wishing to set up IPF registries and in time for a global IPF registry.

Mycobacterial carbonic anhydrases, such as the essential protein Rv3588c, are attractive drug targets since they constitute a different class of carbonic anhydrases than those found in humans. A natural product library has been screened for compounds that inhibit mycobacterial carbonic anhydrases but lack the much-exploited sulfonamide/sulfamate group. The identified inhibitors of mycobacterial Rv3588c are likely to affect the enzyme at a site different from the catalytic centre – a concept which may be exploited for novel specific anti-mycobacterials.

Background and objective The aims of this observational study were (i) to examine the prevalence of symptomatic and clinically silent proximal and distal gastro-oesophageal reflux (GOR) in adults with chronic obstructive pulmonary disease (COPD) or bronchiectasis, (ii) the presence of gastric aspiration, and (iii) to explore the possible clinical significance of this comorbidity in these conditions. Methods Twenty-seven participants with COPD, 27 with bronchiectasis and 17 control subjects completed reflux symptom evaluation and dual-channel 24 h oesophageal pH monitoring. In those with lung disease, pepsin levels in sputum samples were measured using enzyme-linked immunosorbent assay, with disease severity (lung function and high-resolution computed tomography) also measured. Results The prevalence of GOR in COPD was 37%, in bronchiectasis was 40% and in control subjects was 18% (P = 0.005). Of those diagnosed with GOR, clinically silent reflux was detected in 20% of participants with COPD and 42% with bronchiectasis. While pepsin was found in 33% of COPD and 26% of bronchiectasis participants, the presence of pepsin in sputum was not related to a diagnosis of GOR based on oesophageal pH monitoring in either condition. Neither a diagnosis of GOR nor the presence of pepsin was associated with increased severity of lung disease in COPD or bronchiectasis. Conclusions The prevalence of GOR in COPD or bronchiectasis is twice that of the control population, and the diagnosis could not be based on symptoms alone. Pepsin was detected in sputum in COPD and bronchiectasis, suggesting a possible role of pulmonary aspiration, which requires further exploration.
