Abstract
OBJECTIVE Antimalarials (AM) are recommended for all systemic lupus erythematosus (SLE) patients without specific contraindications. Their main adverse effect is retinal damage; however, heart disease has been described in isolated cases. The aim of our study is to describe 8 patients with AM-induced cardiomyopathy (AMIC) in a defined SLE cohort. METHODS Patients attending the Toronto Lupus Clinic and diagnosed with definite (based on endomyocardial biopsy; EMB) and possible AMIC were included [based on cardiac magnetic resonance imaging (cMRI) and other investigations]. RESULTS Eight female patients (median age 62.5 yrs, disease duration 35 yrs, AM use duration 22 yrs) were diagnosed with AMIC in the past 2 years. Diagnosis was based on EMB in 3 (extensive cardiomyocyte vacuolation, intracytoplasmic myelinoid, and curvilinear bodies). In 4 patients, cMRI was highly suggestive of AMIC (ventricular hypertrophy and/or atrial enlargement and late gadolinium enhancement in a nonvascular pattern). Another patient was diagnosed with complete atrioventricular block, left ventricular and septal hypertrophy, along with concomitant ocular toxicity. All patients had abnormal cardiac troponin I (cTnI) and brain natriuretic peptide (BNP), whereas 7/8 also had chronically elevated creatine phosphokinase. During followup, 1 patient died from refractory heart failure. In the remaining patients, hypertrophy regression and a steady decrease of heart biomarkers were observed after AM cessation. CONCLUSION Once considered extremely rare, AMIC seems to be underrecognized, probably because of the false attribution of heart failure or hypertrophy to other causes. Certain biomarkers (cTnI, BNP) and imaging findings may lead to early diagnosis and enhance survival.

Abstract
Symptom recognition and self-management is instrumental in reducing the number of deaths related to coronary artery disease (CAD) in women. The purpose of this study was to synthesize qualitative research evidence on the self-management of cardiac pain and associated symptoms in women. Seven databases were systematically searched, and the concepts of the Individual and Family Self-Management Theory were used as the framework for data extraction and analysis. Search strategies yielded 22,402 citations, from which 35 qualitative studies were included in a final meta-summary, comprising data from 769 participants, including 437 (57%) women. The available literature focused cardiac pain self-management from a binary sex and gender perspective. Ethnicity was indicated in 19 (54%) studies. Results support individualized intervention strategies that promote goal setting and action planning, management of physical and emotional responses, and social facilitation provided through social support.

Abstract
OBJECTIVE Cardiac involvement in systemic lupus erythematosus (SLE) is often undiagnosed in its early phases. Specific heart biomarkers may identify patients at risk. We sought to investigate the prevalence and associated factors for such biomarkers in SLE. METHODS Brain natriuretic peptide (BNP) and cardiac troponin I (cTnI) were measured simultaneously in 151 consecutive patients with no history of heart disease or pulmonary arterial hypertension (PAH). None had electrocardiographic abnormalities suggestive of acute coronary syndrome. Cross-sectional comparisons and logistic regression analyses were performed. Patients with abnormal biomarkers were investigated to delineate the specific cause. RESULTS Sixteen patients (16/151, 10.6%) had elevated BNP, and 9 of them also had abnormal cTnI. Compared to subjects with normal biomarkers, they were older, had longer disease and antimalarial (AM) use duration, and more frequently persistent creatine phosphokinase (CPK) elevation. Multivariable regression analysis showed prolonged AM treatment (> 5.6 yrs) and persistent CPK elevation to be important predictors for elevated cardiac biomarkers. Six patients were diagnosed with definite (based on endomyocardial biopsy, n = 2) or possible (based on cardiac magnetic resonance after exclusion of other causes) AM-induced cardiomyopathy (AMIC); all had both BNP and cTnI elevated. Alternative causes were identified in 5, while no definitive diagnosis could be made in the remaining patients. CONCLUSION About 10% of patients with SLE had elevated myocardial biomarkers, in the absence of prior cardiac disease or PAH. One-third of them were diagnosed with AMIC. Prolonged AM therapy and persistent CPK elevation conferred an increased risk for abnormal BNP and cTnI, which might predict AMIC.

Abstract
OBJECTIVES Cardiotoxicity with potential conduction/structural abnormalities on electrocardiogram (ECG) have been reported with anti-malarial (AM). We aimed to study whether cumulative AM is associated with ECG abnormalities. METHODS A standard resting supine ECG was performed on consecutive patients attending the Lupus Clinic since 2012. ECG abnormalities were grouped into structural [left ventricular hypertrophy or atrial enlargement] and conduction abnormalities [prolonged corrected QT interval (QTc), short PR interval, left bundle branch block (LBBB), right bundle branch block (RBBB) and atrioventricular block (AVB), bradycardia, tachycardia, premature atrial complex, ectopic atrial rhythm, atrial fibrillation, premature ventricular complex and ventricular bigeminy]. Associations between cumulative AM and ECG abnormalities (structural or conduction) were assessed using logistic regression analysis (after adjusting for baseline patient characteristics) and in a nested case-control study (1:3). RESULTS Of 453 patients treated with AM, the median cumulative AM was 1207 grams at ECG. Conduction abnormalities were more prevalent than structural abnormalities, 71 (15.7%) vs. 58 (12.8%). AM cumulative dose did not show a statistical significant association with ECG structural abnormalities, (OR 1.82, p=0.07) while it was protective for conduction ECG abnormalities (OR 0.42, p=0.006). The nested case-control analysis also found that AM cumulative dose is protective against conduction ECG abnormalities (OR 0.36, p=0.0007). SLE duration was a risk factor for both structural and conduction ECG abnormalities. CONCLUSIONS This study suggests an association between cumulative AM dose above the median (1207 g) and structural ECG abnormalities. More importantly, cumulative AM decreases the odds of ECG conduction abnormalities.

Abstract
Background Severe brady-arrhythmias, requiring a permanent pacemaker (PPM), have been sparsely reported in systemic lupus erythematosus (SLE). The aim of this study was to describe the characteristics of such arrhythmias in a defined lupus cohort. Patients and methods The database of the Toronto Lupus Clinic ( n = 1366) was searched for patients who received a PPM. Demographic, clinical, immunological and therapeutic variables along with electrocardiographic (ECG) and echocardiographic findings (based on the last available test prior to PPM) were analyzed. Patients with a PPM (cases) were compared with age-, sex- and disease duration-matched patients without a PPM (controls). Analysis was performed with SAS 9.0; p < 0.05 was considered significant. Results Eighteen patients were identified, 13 (0.95%) with complete atrioventricular block and 5 (0.37%) with sick sinus syndrome. Disease duration at PPM implantation was 22 ± 12 years. Compared to controls, cases had more frequently coronary artery disease, hypertension, dyslipidemia and longer antimalarial (AM) treatment duration. The prevalence of first-degree atrioventricular block, right bundle branch block, left anterior fascicular block and septal hypertrophy was also higher. AM treatment was significantly associated with brady-arrhythmias (OR = 1.128, 95% CI = 1.003–1.267, p = 0.044). Nine patients had prior heart disease and one received a PPM two years after renal transplantation. Eight patients did not have any potential risk factors; prolonged AM therapy (mean 22 years) might have been the cause. Conclusions Apart from known causes, prolonged AM treatment may be associated with severe brady-arrhythmias in SLE. Certain ECG and echocardiographic characteristics may represent indicators of an ongoing damage in the conduction system.

Abstract
We present a technique for treating retinopathy of prematurity (ROP) with cryotherapy under general anesthesia, administered and monitored by a neonatologist, with endotracheal intubation in the neonatal intensive care unit that avoids the serious systemic complications associated with the administration of local anesthetics. Although no significant complications arose in this series, having the intubated infant monitored by trained neonatology staff allows appropriate management should complications arise. We have used this technique to treat 20 eyes with threshold ROP. The mean time to extubation was 40.2 hours. The systemic status and discharge from the neonatal intensive care unit were not influenced by the general anesthesia. This technique allows quick and accurate application of the cryotherapy in a stable and controlled setting. We recommend that physicians consider cryotherapy under general anesthesia with endotracheal intubation for infants with ROP. This technique allows ROP to be treated adequately with minimal risk to the infant.

Abstract
BACKGROUND Cardiac pain is considered the primary indicator of coronary artery disease (CAD). Existing reviews lack appropriate numbers of women or sex-based subgroup analyses, or both; thus, the benefits of self-management (women with cardiac pain actively participating in their own care and treatment) remain uncertain. METHODS Using methods described by the Evidence for Policy and Practice Information and Co-ordinating Centre at the Institute of Education, 7 databases were systematically searched to examine and synthesize the evidence on self-management interventions for women with cardiac pain and cardiac pain equivalents, such as fatigue, dyspnea, and exhaustion. RESULTS Our search yielded 22,402 article titles and abstracts. Of these, 57 randomized controlled trials were included in a final narrative synthesis, comprising data from 13,047 participants, including 5299 (41%) women. Self-management interventions targeting cardiac pain in women compared with a control population reduced (1) cardiac pain frequency and cardiac pain proportion (obstructive and nonobstructive CAD), (2) fatigue at 12 months, and (3) dyspnea at 2 months. There was no evidence of group differences in postprocedural (percutaneous coronary intervention or cardiac surgery) pain. Results indicated that self-management interventions for cardiac pain were more effective if they included a greater proportion of women (standardized mean difference [SMD], -0.01; standard error, 0.003; P = 0.02), goal setting (SMD, -0.26; 95% confidence interval [CI], -0.49 to -0.03), and collaboration/support from health care providers (SMD, -0.57; 95% CI, -1.00 to -0.14). CONCLUSIONS The results of this review suggest that self-management interventions reduce cardiac pain and cardiac pain equivalents.

Abstract
OBJECTIVE We aimed to estimate the proportion of underdiagnosis and undertreatment of cardiovascular risk factors (CVRF) in an international multicenter cohort of patients with psoriasis and psoriatic arthritis (PsA). METHODS A cross-sectional analysis was conducted of patients with psoriatic disease from the International Psoriasis and Arthritis Research Team cohort. The presence of modifiable CVRF [diabetes, hypertension (HTN), dyslipidemia, smoking, elevated body mass index, and central obesity] and the use of appropriate therapies for HTN and dyslipidemia were determined. The 10-year CV risk was calculated according to the Framingham Risk Score. Physician adherence with guidelines for the treatment of dyslipidemia and HTN was assessed. Regression analysis was used to assess predictors of undertreatment of HTN and dyslipidemia. RESULTS A total of 2254 patients (58.9% PsA, 41.1% psoriasis) from 8 centers in Canada, the United States, and Israel were included. Their mean age was 52 ± 13.8 years and 53% were men. Of the patients, 87.6% had at least 1 modifiable CVRF, 45.1% had HTN, 49.4% dyslipidemia, 13.3% diabetes, 75.3% were overweight or obese, 54.3% central obesity, and 17.3% were current smokers. We found 59.2% of patients with HTN and 65.6% of patients with dyslipidemia were undertreated. Undertreatment was associated with younger age (≤ 50 yrs), having psoriasis, and male sex. CONCLUSION In real-world settings, a large proportion of patients with psoriasis and PsA were underdiagnosed and undertreated for HTN and dyslipidemia. Strategies to improve the management of CVRF in psoriatic patients are warranted.

Abstract
OBJECTIVE To describe the current evidence related to the self-management of cardiac pain in women using the process and methodology of evidence mapping. DESIGN AND SETTING Literature search for studies that describe the self-management of cardiac pain in women greater than 18 years of age, managed in community, primary care or outpatient settings, published in English or a Scandinavian language between 1 January 1990 and 24 June 2016 using AMED, CINAHL, ERIC, EMBASE, MEDLINE, Proquest, PsychInfo, the Cochrane Library, Scopus, Swemed+, Web of Science, the Clinical Trials Registry, International Register of Controlled Trials, MetaRegister of Controlled Trials, theses and dissertations, published conference abstracts and relevant websites using GreyNet International, ISI proceedings, BIOSIS and Conference papers index. Two independent reviewers screened using predefined eligibility criteria. Included articles were classified according to study design, pain category, publication year, sample size, per cent women and mean age. INTERVENTIONS Self-management interventions for cardiac pain or non-intervention studies that described views and perspectives of women who self-managed cardiac pain. PRIMARY AND SECONDARY OUTCOMES MEASURES Outcomes included those related to knowledge, self-efficacy, function and health-related quality of life. RESULTS The literature search identified 5940 unique articles, of which 220 were included in the evidence map. Only 22% (n=49) were intervention studies. Sixty-nine per cent (n=151) of the studies described cardiac pain related to obstructive coronary artery disease (CAD), 2% (n=5) non-obstructive CAD and 15% (n=34) postpercutaneous coronary intervention/cardiac surgery. Most were published after 2000, the median sample size was 90 with 25%-100% women and the mean age was 63 years. CONCLUSIONS Our evidence map suggests that while much is known about the differing presentations of obstructive cardiac pain in middle-aged women, little research focused on young and old women, non-obstructive cardiac pain or self-management interventions to assist women to manage cardiac pain.

Abstract
INTRODUCTION The prevalence of disordered gambling worldwide has been estimated at 2.3%. Only a small minority of disordered gamblers seek specialist face-to-face treatment, and so a need for alternative treatment delivery models that capitalise on advances in communication technology, and use self-directed activity that can complement existing services has been identified. As such, the primary aim of this study is to evaluate an online self-directed cognitive-behavioural programme for disordered gambling (GamblingLess: For Life). METHODS AND ANALYSIS The study will be a 2-arm, parallel group, pragmatic randomised trial. Participants will be randomly allocated to a pure self-directed (PSD) or guided self-directed (GSD) intervention. Participants in both groups will be asked to work through the 4 modules of the GamblingLess programme over 8 weeks. Participants in the GSD intervention will also receive weekly emails of guidance and support from a gambling counsellor. A total of 200 participants will be recruited. Participants will be eligible if they reside in Australia, are aged 18 years and over, have access to the internet, have adequate knowledge of the English language, are seeking help for their own gambling problems and are willing to take part in the intervention and associated assessments. Assessments will be conducted at preintervention, and at 2, 3 and 12 months from preintervention. The primary outcome is gambling severity, assessed using the Gambling Symptom Assessment Scale. Secondary outcomes include gambling frequency, gambling expenditure, psychological distress, quality of life and additional help-seeking. Qualitative interviews will also be conducted with a subsample of participants and the Guides (counsellors). ETHICS AND DISSEMINATION The study has been approved by the Deakin University Human Research and Eastern Health Human Research Ethics Committees. Findings will be disseminated via report, peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER ACTRN12615000864527; results.

Abstract
OBJECTIVES To examine the effect of Osteoarthritis (OA)-related difficulty walking on risk for diabetes complications in persons with diabetes and OA. DESIGN A population cohort aged 55+ years with symptomatic hip and knee OA was recruited 1996-98 and followed through provincial administrative data to 2015 (n = 2,225). In those with confirmed OA (examination and radiographs) and self-reported diabetes at baseline (n = 359), multivariate Cox regression modeling was used to examine the relationship between baseline difficulty walking (Health Assessment Questionnaire (HAQ) difficulty walking score; use of walking aid) and time to first diabetes-specific complication (hospitalization for hypo- or hyperglycemia, infection, amputation, retinopathy, or initiation of chronic renal dialysis) and cardiovascular (CV) events. RESULTS Participants' mean baseline age was 71.4 years; 66.9% were female, 77.7% had hypertension, 54.0% had pre-existing CV disease, 42.9% were obese and 15.3% were smokers. Median HAQ difficulty walking score was 2/3 indicating moderate to severe walking disability; 54.9% used a walking aid. Over a median 6.1 years, 184 (51.3%) experienced one or more diabetes-specific complications; 191 (53.2%) experienced a CV event over a median 5.7 years. Greater baseline difficulty walking was associated with shorter time to the first diabetes-specific complication (adjusted HR per unit increase in HAQ walking 1.24, 95% CI 1.04-1.47, P = 0.02) and CV event (adjusted HR for those using a walking aid 1.35, 95% CI 1.00-1.83, P = 0.04). CONCLUSIONS In a population cohort with OA and diabetes, OA-related difficulty walking was a significant - and potentially modifiable - risk factor for diabetes complications.

Abstract
The DISTINCT study (reDefining Intervention with Studies Testing Innovative Nifedipine GITS-Candesartan Therapy) investigated the efficacy and safety of nifedipine GITS/candesartan cilexetil combinations vs respective monotherapies and placebo in patients with hypertension. This descriptive sub-analysis examined blood pressure (BP)-lowering effects in high-risk participants, including those with renal impairment (estimated glomerular filtration rate<90 ml min-1, n=422), type 2 diabetes mellitus (n=202), hypercholesterolaemia (n=206) and cardiovascular (CV) risk factors (n=971), as well as the impact of gender, age and body mass index (BMI). Participants with grade I/II hypertension were randomised to treatment with nifedipine GITS (N) 20, 30, 60 mg and/or candesartan cilexetil (C) 4, 8, 16, 32 mg or placebo for 8 weeks. Mean systolic BP and diastolic BP reductions after treatment in high-risk participants were greater, overall, with N/C combinations vs respective monotherapies or placebo, with indicators of a dose-response effect. Highest rates of BP control (ESH/ESC 2013 guideline criteria) were also achieved with highest doses of N/C combinations in each high-risk subgroup. The benefits of combination therapy vs monotherapy were additionally observed in patient subgroups categorised by gender, age or BMI. All high-risk participants reported fewer vasodilatory adverse events in the pooled N/C combination therapy than the N monotherapy group. In conclusion, consistent with the DISTINCT main study outcomes, high-risk participants showed greater reductions in BP and higher control rates with N/C combinations compared with respective monotherapies and lesser vasodilatory side-effects compared with N monotherapy.

Abstract
In premenopausal women, ovarian steroids are felt to play a role in the prevention of cardiovascular disease. We aimed to assess whether menstrual cycle variations in estrogen can modify the response to ischemia-reperfusion (IR) injury in humans. In an investigator-blinded crossover study, 10 healthy premenopausal women with regular menstrual cycles were studied. They had flow-mediated dilatation (FMD) measured by ultrasound in the radial artery before and after IR (15 min of brachial artery ischemia, 15 min of reperfusion) during both the early and late follicular phases of the menstrual cycle. The order of these visits was not randomized. IR significantly blunted FMD in the early follicular phase (pre-IR: 7.1% ± 1.0%; post-IR: 3.6% ± 1.0%, P = 0.01) when estradiol levels were low (148.4 ± 19.8 pmol/L). Conversely, FMD was preserved after IR during the late follicular phase (pre-IR: 7.2% ± 0.9%; post-IR: 7.0% ± 0.8%, P = NS, P = 0.03 compared with early follicular) when estradiol levels were high (825.7 ± 85.8 pmol/L, P < 0.001 compared with early follicular). There was a significant inverse relationship between estradiol concentration and IR-induced endothelial dysfunction (i.e., change in FMD after IR) (r = 0.59, r2 = 0.36, P < 0.01). These findings demonstrate, for the first time in humans, a clear relationship between the cyclical changes in serum concentrations of estradiol and the endothelium's response to IR.
