AAV9:PKP2 improves heart function and survival in a Pkp2-deficient mouse model of arrhythmogenic right ventricular cardiomyopathy. COMMUNICATIONS MEDICINE 2024; 4:38. [PMID: 38499690 PMCID: PMC10948840 DOI: 10.1038/s43856-024-00450-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 02/01/2024] [Indexed: 03/20/2024] Open
Abstract
BACKGROUND Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a familial cardiac disease associated with ventricular arrhythmias and an increased risk of sudden cardiac death. Currently, there are no approved treatments that address the underlying genetic cause of this disease, representing a significant unmet need. Mutations in Plakophilin-2 (PKP2), encoding a desmosomal protein, account for approximately 40% of ARVC cases and result in reduced gene expression. METHODS Our goal is to examine the feasibility and the efficacy of adeno-associated virus 9 (AAV9)-mediated restoration of PKP2 expression in a cardiac specific knock-out mouse model of Pkp2. RESULTS We show that a single dose of AAV9:PKP2 gene delivery prevents disease development before the onset of cardiomyopathy and attenuates disease progression after overt cardiomyopathy. Restoration of PKP2 expression leads to a significant extension of lifespan by restoring cellular structures of desmosomes and gap junctions, preventing or halting decline in left ventricular ejection fraction, preventing or reversing dilation of the right ventricle, ameliorating ventricular arrhythmia event frequency and severity, and preventing adverse fibrotic remodeling. RNA sequencing analyses show that restoration of PKP2 expression leads to highly coordinated and durable correction of PKP2-associated transcriptional networks beyond desmosomes, revealing a broad spectrum of biological perturbances behind ARVC disease etiology. CONCLUSIONS We identify fundamental mechanisms of PKP2-associated ARVC beyond disruption of desmosome function. The observed PKP2 dose-function relationship indicates that cardiac-selective AAV9:PKP2 gene therapy may be a promising therapeutic approach to treat ARVC patients with PKP2 mutations.

Associations between DAPT score and long-term mortality post PCI. Eur Heart J 2022.

Abstract
Abstract
Introduction
The dual antiplatelet therapy (DAPT) score was developed to identify patients more likely to derive benefit (score ≥2) or harm (score <2) from DAPT beyond 1-year post PCI. There is no study which looked at the DAPT score and long term outcomes post PCI in Australia.
Purpose
We sought to examine long-term mortality after PCI by the DAPT score in patients treated with DAPT per local guidelines.
Methods
We examined data from the MIG PCI database from 2005 to 2018 in whom the DAPT score could be derived and grouped them as score ≥2 or <2. Long-term mortality was assessed from National Death Index linkage. The primary endpoint was long-term mortality examined using survival analysis. Secondary endpoints included 30-day ischaemic outcomes and in-hospital major bleeding.
Results
Out of 27,740 patients in the study, 9,401 (33.9%) had DAPT score ≥2. They were younger and included more females and higher prevalence of renal impairment. DAPT score ≥2 patients had higher in-hospital major bleeding, 30-day mortality, MI and target vessel revascularisation. DAPT score ≥2 patients had lower long-term survival to 12 years (p<0.001 for all).
Conclusion
A third of all-comer PCI patients had DAPT score ≥2 with greater short-term risk of ischaemic and bleeding outcomes, as well as long-term mortality. Theoretically, those with DAPT score ≥2 would benefit from longer duration of DAPT as ischaemic risk outweighs bleeding risk. However, given our finding of increased short-term bleeding risk and long-term mortality, dynamic bleeding risk assessment should be undertaken to guide pharmacotherapy strategies.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

1005 HEALTH-RELATED QUALITY OF LIFE AND FUTURE RISK OF HEALTH OUTCOMES AMONG OLDER ADULTS LIVING IN AUSTRALIA AND THE UNITED STATES. Age Ageing 2022.

Abstract
Abstract
Introduction
Poor health-related quality of life (HRQoL) is associated with higher morbidity and mortality in patient populations. However, whether HRQoL is associated with health outcomes among community-dwelling older people requires further investigation. This study aimed to examine whether HRQoL predicts cognitive decline, dementia, cardiovascular disease (CVD), and mortality in community-dwelling older people living in Australia and the United States.
Method
A cohort of 19,106 individuals from the ASPirin in Reducing Events in the Elderly (ASPREE) study, aged 65–98 years, initially free of dementia or CVD, and who completed the HRQoL 12-item short form (SF-12, version-2) at baseline (2010–2014), were followed until June 2017. The physical (PCS) and mental component scores (MCS) of SF-12 were generated using standardized norm-based method.
Results
Over a median of 4.7 years, there were 2,412 cognitive declines, 574 dementia, 922 incident CVD events, and 1,052 deaths. Using Cox proportional-hazard regression adjusted for a range of covariates, every 10-unit increase in PCS was associated with a 6% lower risk of cognitive decline, a 14% lower risk of incident CVD, and 17% lower risk of all-cause mortality, but was not associated with incident dementia. In contrast, higher MCS was only associated with a 12% and 15% lower risk of cognitive decline and dementia, respectively. Findings did not differ by sex.
Conclusion
Our study provides some of the first evidence that HRQoL can be used in combination with clinical data to identify the future risks of health outcomes among older individuals living in the community. Our findings support the decision of the Australian Commission on Safety and Quality in Health Care to incorporate the SF-12 into the annual Patient-Reported Outcome Measures (PROMs assessment.

Abstract
Abstract
Background
In patients with prior CABG requiring subsequent PCI there is uncertainty whether bypass grafts or native coronary arteries should be targeted.
Methods
We analysed data from 2,764 patients with prior CABG in the Melbourne Interventional Group registry (2005–2018), divided into two groups: those undergoing PCI to a native vessel (n=1,928) and those with PCI to a graft vessel (n=836).
Results
Patients with a graft vessel PCI were older, had more high-risk clinical characteristics (prior MI, heart failure, ejection fraction <50%, renal impairment, peripheral and cerebrovascular disease), and high-risk procedural features (ACC/AHA types B2/C lesions). However, patients in the native vessel group were more likely to have PCI to a chronic total occlusion. The majority of graft PCI were to saphenous vein grafts (84%), with 10% to radial and 6% to LIMA/RIMA grafts. Distal embolic protection devices were used in 30% of graft PCI. Patients with graft PCI had higher rates of no reflow (6.3% vs. 1.5%; p<0.001), coronary perforation (p=0.016) and inpatient stent thrombosis (p=0.028). However, 30-day mortality and major adverse cardiovascular and cerebrovascular events (MACCE) were similar. Unadjusted long-term mortality (median follow up 4.8 years) was higher in patients who had undergone a graft PCI (44% vs. 32%, p<0.001), but following Cox proportional hazards modelling, PCI vessel type was not a predictor of long-term mortality (HR 1.13; 95% CI 0.96–1.33, p=0.14).
Conclusions
Early clinical outcomes and risk-adjusted long-term mortality are similar for patients with prior CABG undergoing PCI to a native vessel or a bypass graft.

Trends in intra-aortic balloon pump use in cardiogenic shock in the post-SHOCK II trial era. Eur Heart J 2021.

Abstract
Abstract
Background
Myocardial infarction complicated by cardiogenic shock (MI-CS) has a poor prognosis, even with early revascularisation. Previously, intra-aortic balloon pump (IABP) use was thought to improve outcomes, but the SHOCK-II trial in 2012 found no survival benefit.
Purpose
This study aimed to determine the trends in IABP use in patients with MI-CS undergoing percutaneous intervention (PCI) over time and characteristics associated with use.
Methods
Between 2005–2018, patients presenting with MI-CS that underwent percutaneous coronary intervention (PCI) at a hospital participating in the Melbourne Interventional Group Registry were included. The primary outcome was the trend in IABP use over time. Secondary outcomes included mortality, 30-day MACCE (major adverse cardiovascular and cerebrovascular events) and predictors of outcome, determined via logistic regression.
Results
Of the 1,110 patients identified, IABP was used in 478 (43%). IABP was used more in patients with left main and left anterior descending culprit lesions (62% vs. 46%), lower ejection fraction (<35%; 18% vs. 11%), and pre-procedural inotrope use (81% vs. 73%), all p<0.05. IABP use was associated with higher inpatient bleeding (18% vs. 13%) and 30-day MACCE (58% vs. 51%), both p<0.05. The rate of MI-CS increased over time, but after 2012 there was a decline in IABP use (Figure 1). IABP use was a predictor of 30-day MACCE (OR 1.6, 95% CI 1.18–2.29, p=0.003). However, IABP was not associated with in-hospital, 30-day or long-term mortality (45% vs. 47%, p=0.44; 46% vs. 50%, p=0.25; 60% vs. 62%, p=0.39).
Conclusions
Consistent with the SHOCK II trial, IABP use is not associated with reduced short- or long-term mortality, but in this study was associated with increased short-term adverse events. IABP use is declining, but is still used in sicker patients with greater myocardium at risk, given limited alternatives.

Abstract
Atrial fibrillation (AF) outcome studies play an essential role in the development of clinical evidence to improve the management of AF patients. Understanding the statistical considerations involved in study design and interpretation is crucial if electrophysiologists are to change practice. In this review, with the guidance of a medical statistician and a clinical trialist we provide an overview of important statistical issues for the clinician, with a focus on clinical studies in AF ablation. Various types of study designs including randomized controlled trials, superiority, and non-inferiority studies are described, along with their implications and limitations. Appropriate sample size calculation is fundamental to ensure statistical power and efficient resource use. Multiplicity in study endpoints is useful to encapsulate the varied effects of an intervention/treatment, although statistical adjustments are required to account for this. Finally, we discuss the limitations with the current primary endpoint used in AF ablation studies, namely, freedom from atrial tachyarrhythmia of >30 seconds, and propose AF burden as a more relevant primary endpoint, based on findings from recent clinical studies. However, technical challenges need to be overcome before AF burden can be routinely adopted, especially the need for non-invasive, long-term monitoring. The emergence of newer technologies, particularly wearable technology, offers significant promise in filling this gap.

Abstract
OBJECTIVE Genetic variants that disrupt the function of the PCSK9 (proprotein convertase subtilisin kexin type 9) and APOB (apolipoprotein B)genes result in lower serum low-density lipoprotein cholesterol (LDL-C) levels and subsequently confer protection against coronary heart disease (CHD). The objective of this study was to measure the prevalence and selective advantage of such variants among healthy older individuals without a history of CHD. METHODS We performed targeted sequencing of the PCSK9 and APOB genes in 13 131 healthy individuals without CHD aged 70 years or older enrolled into the ASPirin in Reducing Events in the Elderly trial. We detected variants in the PCSK9 and APOB genes with predicted loss-of-function. We associated variant carrier status with serum LDL-C and total cholesterol (TC) levels at the time of study enrolment, adjusting for statin use. RESULTS We detected 22 different rare PCSK9/APOB candidate variants with putative lipid-lowering effect, carried by 104 participants (carrier rate 1 in 126). Serum LDL-C and TC concentrations for rare PCSK9/APOB variant carriers were consistently lower than non-carriers. Rare variant carrier status was associated with 19.4 mg/dL (14.6%) lower LDL-C, compared with non-carriers (p≤0.001, adjusted for statin use). Statin prescriptions were less prevalent in rare variant carriers (16%) than non-carriers (35%). The more common PCSK9 R46L variant (rs11591147-T) was associated with 15.5 mg/dL (11.8%) lower LDL-C in heterozygotes, and 25.2 mg/dL (19.2%) lower LDL-C in homozygotes (both p≤0.001). CONCLUSIONS Lipid-lowering genetic variants are carried by healthy older individuals and contribute to CHD-free survival. TRIAL REGISTRATION NUMBER NCT01038583.

Abstract
Background Health and medical research funding agencies are increasingly interested in measuring the impact of funded research. We present a research impact case study for the first four years of an Australian National Health and Medical Research Council funded Centre of Research Excellence in Cardiovascular Outcomes Improvement (2016–2020). The primary aim of this paper was to explore the application of a research impact matrix to assess the impact of cardiovascular outcomes improvement research. Methods We applied a research impact matrix developed from a systematic review of existing methodological frameworks used to measure research impact. This impact matrix was used as a bespoke tool to identify and understand various research impacts over different time frames. Data sources included a review of existing internal documentation from the research centre and publicly available information sources, informal iterative discussions with 10 centre investigators, and confirmation of information from centre grant and scholarship recipients. Results By July 2019, the impact on the short-term research domain category included over 41 direct publications, which were cited over 87 times (median journal impact factor of 2.84). There were over 61 conference presentations, seven PhD candidacies, five new academic collaborations, and six new database linkages conducted. The impact on the mid-term research domain category involved contributions towards the development of a national cardiac registry, cardiovascular guidelines, application for a Medicare Benefits Schedule reimbursement item number, introduction of patient-reported outcome measures into several databases, and the establishment of nine new industry collaborations. Evidence of long-term impacts were described as the development and use of contemporary management for aortic stenosis, a cardiovascular risk prediction model and prevention targets in several data registries, and the establishment of cost-effectiveness for stenting compared to surgery. Conclusions We considered the research impact matrix a feasible tool to identify evidence of academic and policy impact in the short- to midterm; however, we experienced challenges in capturing long-term impacts. Cost containment and broader economic impacts represented another difficult area of impact to measure.

Abstract
The 'plain pumpkin-beetle', indica species-complex of Aulacophora Chevrolat, 1836, is revised for Australopapua, Timor and the West Pacific. The species-complex is defined and the following eight included species are diagnosed and described: A. abdominalis (Fabricius, 1781); A. barrogae Reid, Halling Beatson, sp. nov.; A. cornuta Baly, 1879; A. indica (Gmelin, 1790); A. mbabaram Reid, Halling Beatson, sp. nov.; A. relicta (Boisduval, 1835); A. wallacii Baly, 1886; A. wilsoni Baly, 1888. The three other similar species in the region of interest, A. bicolor (Weber, 1801), A coffeae (Weber, 1801) and A. deplanchei (Perroud Montrouzier, 1864), are diagnosed from the Aulacophora indica species-complex and a key is provided for all 11 species. New synonyms are noted as follows (senior synonym first): A. abdominalis (Fabricius, 1781) = A. argyrogaster (Montrouzier, 1861) syn. nov., = A. fabricii Baly, 1886 syn. nov., = A. armigera Baly, 1889 syn. nov., = A. aruensis (Weise, 1892) syn. nov., = A. fauveli Beenen, 2008 syn. nov.; A. relicta (Boisduval, 1835) = A. palmerstoni Blackburn, 1888 syn. nov., = A. imberbis Weise, 1916 syn. nov.. Aulacophora relicta (stat. rev.) is revalidated from synonymy with A. abdominalis and A. wilsoni (stat. rev.) is revalidated from synonymy with A. scutellata (Boisduval 1835). Aulacophora flava Olivier, 1808, is not an available species name. The synonymy of A. robusta Duvivier, 1884 with A. cornuta is confirmed. Five species traditionally placed in Aulacophora, Galleruca flaveola Boisduval, 1835, G. punctata Boisduval, 1835, G. scutellata Boisduval, 1835, Galleruca flavescens Montrouzier, 1856 and Galleruca artensis Montrouzier, 1861, are not identifiable to genus or species and are therefore listed as nomina dubia within Galerucinae. The previously designated lectotype of A. abdominalis is shown to be invalid. Neotypes are created for A. abdominalis and A. relicta as both lack original type material. A lectotype is designated for A. palmerstoni. The plain pumpkin-beetle species are distributed as follows: A. barrogae, A. mbabaram, A. relicta and A. wilsoni are endemic to Australia; A. abdominalis is widespread in the southwestern Pacific and Melanesia, west to Timor and east to Niue, but is absent from mainland Australia; A. cornuta is widespread from eastern India to Melanesia as far east as Guadalcanal; A. indica is widespread from India southeast to Timor and northeast to Guam, and adventitious further south and east, but absent from, or not established in, Australia, Fiji, New Caledonia, Niue, Samoa, Tonga and Vanuatu; A. wallacii is endemic to Timor. Native hosts are unknown for any species, but A. abdominalis, A. indica, A. relicta and A. wallacii are pests of exotic cucurbit crops.

Linkage of Australian national registry data using a statistical linkage key. BMC Med Inform Decis Mak 2021; 21:37. [PMID: 33531002 PMCID: PMC7856707 DOI: 10.1186/s12911-021-01393-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 01/11/2021] [Indexed: 11/24/2022] Open
Abstract
Background Data from clinical registries may be linked to gain additional insights into disease processes, risk factors and outcomes. Identifying information varies from full names, addresses and unique identification codes to statistical linkage keys to no direct identifying information at all. A number of databases in Australia contain the statistical linkage key 581 (SLK-581). Our aim was to investigate the ability to link data using SLK-581 between two national databases, and to compare this linkage to that achieved with direct identifiers or other non-identifying variables. Methods The Australian and New Zealand Society of Cardiothoracic Surgeons database (ANZSCTS-CSD) contains fully identified data. The Australian and New Zealand Intensive Care Society database (ANZICS-APD) contains non-identified data together with SLK-581. Identifying data is removed at participating hospitals prior to central collation and storage. We used the local hospital ANZICS-APD data at a large single tertiary centre prior to deidentification and linked this to ANZSCTS-CSD data. We compared linkage using SLK-581 to linkage using non-identifying variables (dates of admission and discharge, age and sex) and linkage using a complete set of unique identifiers. We compared the rate of match, rate of mismatch and clinical characteristics between unmatched patients using the different methods. Results There were 1283 patients eligible for matching in the ANZSCTS-CSD. 1242 were matched using unique identifiers. Using non-identifying variables 1151/1242 (92.6%) patients were matched. Using SLK-581, 1202/1242 (96.7%) patients were matched. The addition of non-identifying data to SLK-581 provided few additional patients (1211/1242, 97.5%). Patients who did not match were younger, had a higher mortality risk and more non-standard procedures vs matched patients. The differences between unmatched patients using different matching strategies were small. Conclusion All strategies provided an acceptable linkage. SLK-581 improved the linkage compared to non-identifying variables, but was not as successful as direct identifiers. SLK-581 may be used to improve linkage between national registries where identifying information is not available or cannot be released.

Optimising a targeted test reduction intervention for patients admitted to the intensive care unit: The Targeted Intensive Care Test Ordering Cluster Trial intervention. Aust Crit Care 2021; 34:419-426. [PMID: 33526330 DOI: 10.1016/j.aucc.2020.11.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 11/03/2020] [Accepted: 11/15/2020] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Approaches to routine diagnostic testing in the intensive care unit include time-scheduled testing and targeted testing. Blood tests and chest radiographs requested on a routine, time-scheduled basis may reduce the risk of missing important findings. Targeted testing, considering individual patient needs, may reduce unnecessary testing, wasted clinician time, and costs. However, existing evidence of targeted testing interventions is generally of low quality, and the optimal testing approach is uncertain. OBJECTIVES The aim of the study was to describe the development of an intervention to reduce unnecessary diagnostic test ordering by clinicians working in intensive care, with the aim of informing the design of a pivotal clinical trial. METHODS The Capability, Opportunity, Motivation-Behaviour model was used as a theoretical framework for change. The intervention components were informed by systematically identifying, assessing, and classifying targeted testing interventions in behavioural terms. Feedback from intensive care clinicians and patients was sought using surveys and a consumer reference group. RESULTS The mean percentage of routine tests considered unnecessary by 201 intensive care clinicians was 33 (standard deviation = 16). When presented with a statement of the pros and cons for targeted versus liberal testing (n = 154), 93 (60%) consumer survey respondents preferred a more liberal approach, 33 (21%) preferred a more restrictive approach, and 28 (18%) were unsure. There were 24 behavioural interventions identified and incorporated into the final intervention. This had five major components: (i) a management committee to acquire, disseminate, and coordinate intervention-related information, (ii) a targeted testing guideline for sites, (iii) educational material for sites, (iv) site medical and nursing champions, and (v) site audit and feedback. CONCLUSIONS Although surveyed intensive care clinicians report substantial unnecessary routine diagnostic testing, on the basis of currently available evidence, consumers prefer a more liberal approach. This feedback, and a framework to identify behavioural interventions, has been used to inform the design of a proposed targeted testing clinical trial.

Abstract
Abstract
Background
Over the last thirty years, there has been exponential growth in the number and scale of national cardiovascular disease registries. We aimed to provide a comprehensive outline of contemporary national cardiac registries across all subspecialties.
Methods
We performed a systematic literature review by searching OvidMedline in August 2019 to identify registries relating to six pre-specified domains (Table). For inclusion, registries had to be national in nature, actively collecting data, and publishing either peer-reviewed publications or online reports.
Results
A total of 24,076 records were identified from six domain-specific Medline searches; 24,057 abstracts were screened with 19,435 non-relevant records excluded; 4,624 full texts were screened with 4,473 non-relevant texts excluded; and 151 registries met inclusion criteria representing 51 countries. Of these, 15 related to cardiac surgery, 27 to arrhythmia (17 device, 5 ablation, 7 atrial fibrillation), 21 to congenital heart disease (14 general, 2 interventional, 4 surgical, and 1 disease specific), 43 to coronary disease or percutaneous coronary intervention (22 PCI, 21 CAD), 27 to heart failure (13 heart failure, 5 transplant, 2 mechanical support, 7 disease specific), and 18 related to structural intervention (3 any, 13 transcatheter aortic valve replacement, 2 mitral intervention). Nine national registries (USA, Sweden, Finland, Denmark, UK, Portugal, Norway, Taiwan, and Singapore) covered multiple domains. Quality scoring using the Monash University Clinical Quality Registry Grading System (a composite score of recruitment, and data completeness, definitions, reliability and validation), demonstrated marked heterogeneity in quality between registries.
Conclusions
Cardiac registries have seen rapid growth, however the use and quality among various subspecialties differs markedly across world regions. Given the multiple benefits, clinicians, funders and health bureaucrats should be encouraged to focus on the range, quality and uptake of national registries.

Abstract
Abstract
Background
Rheumatoid arthritis (RA) is the most common inflammatory arthritis and is associated with increased risk of cardiovascular events and mortality. Despite this, data regarding long-term outcomes following percutaneous coronary intervention (PCI) are limited.
Methods
We identified 756 patients with RA from the Melbourne Interventional Group PCI registry (2005–2018) and compared outcomes to the remaining cohort (N=38,579). Cox regression analysis was performed to assess risk of adverse cardiac events including long-term mortality (derived from linkage with the National Death Index [NDI]).
Results
Patients with RA were older (68.9±10.0 vs. 64.6±12.0 years) and more often female (40% vs. 23%), with higher rates of hypertension (70% vs 67%), previous stroke (9% vs 6%), peripheral vascular disease (9% vs 6%), obstructive sleep apnoea (10% vs 5%), chronic lung disease (22% vs 12%), prior myocardial infarction (32% vs 27%), and impaired renal function (eGFR<60 ml/min/1.73m2 in 31% vs 24%), while rates of current smoking were lower (20% vs. 25%), all p<0.05. Lesions were more frequently complex (ACC/AHA type B2/C in 61% vs 57%), required longer stents (>20mm in 39% vs 35%), and rates of no reflow were higher (5% vs 3%), all p<0.05. 30-day mortality was higher (4.4% vs. 3.3%, p=0.04) mainly owing to higher non-cardiac mortality (1.6% vs. 0.8%, p=0.01). National Death Index-linked long-term mortality was 28% vs. 19% (p<0.01) with mean follow-up 4.6 vs. 5.4 years. Risk of 30-day and long-term mortality (including by indication subgroup) are presented in the Table.
Conclusions
Patients with RA undergoing PCI have more comorbidities and longer, more complex coronary lesions. After adjustment, risk of short-term adverse outcomes are similar, while risk of long-term mortality is higher, particularly among patients with acute coronary syndromes.

The significance of internal calcifications on perinatal post-mortem radiographs. Clin Radiol 2020; 75:561.e25-561.e34.

Abstract
AIM To determine whether the presence of internal calcifications on perinatal post-mortem skeletal surveys (PMSS) are associated with certain diagnoses of fetal loss. METHODS AND MATERIALS A 6-month retrospective, single-centre, cohort study was conducted on PMSS performed for perinatal death assessment. One reader re-reviewed all PMSS images for the presence and location of internal calcifications, and noted whether these were included within the original radiology report. Findings at autopsy were then reviewed independently by a second researcher and cause of fetal loss or main diagnosis recorded. Chi-squared tests were conducted to identify differences between those with and without internal calcifications at PMSS. RESULTS Two hundred and thirty perinatal deaths (mean gestational age 18 weeks; average 12–35 weeks) were included in the study, of which 42 (18.3%) demonstrated intra-abdominal calcifications, and 16/42 (38.1%) were mentioned in the radiology reports. Most calcifications were found to be within the lumen of the gastrointestinal tract, and in the left upper quadrant of the abdomen. There was no statistical difference between identifiable causes for fetal loss at autopsy in cases with and without calcification at PMSS (59.5% versus 58.5% respectively, p=0.904). Nevertheless, where calcification and a cause for fetal loss were found, the aetiology was more likely to be due a fetal rather than placental issue. CONCLUSION The presence of internal calcifications on PMSS was not associated with an increased likelihood of explainable fetal loss or particular diagnosis at autopsy. Fetal calcifications on post-mortem skeletal surveys are not significantly associated with causes of fetal loss. When present, internal calcifications were usually seen in lower gestational aged fetuses, intra-abdominal in location, with the majority being intraluminal. The majority of radiologists do not report internal fetal calcifications on radiographs, without significant consequences for final outcome at autopsy.
