BACKGROUND

We aimed to determine whether obesity in women with systemic lupus erythematosus (SLE) independently associates with worse patient-reported outcomes (PROs).

METHODS

Data derive from a prospective study of adult women who carried a diagnosis of SLE verified by medical record review. Two established definitions for obesity were used: fat mass index (FMI) ≥ 13 kg/m and BMI ≥ 30 kg/m . Dependent variables included 4 validated PROs: disease activity via Systemic Lupus Activity Questionnaire (SLAQ), depressive symptoms via Center for Epidemiologic Studies Depression Scale (CES-D), pain via Short Form 36 Health Survey (SF-36) Pain Subscale, and fatigue via SF-36 Vitality Subscale. We used multivariable linear regression to evaluate the associations of obesity with PROs while controlling for potential confounders (age, race, education, income, smoking, disease duration, disease damage, and prednisone use).

RESULTS

The analysis included 148 participants; 32% were obese. In the multivariate regression model, obesity associated with worse scores on each PRO. Mean adjusted scores for SLAQ and CES-D comparing obese versus non-obese participants were 14.8 versus 11.1 (p=0.01) and 19.8 versus 13.1 (p<0.01), respectively. The obese group also reported worse mean adjusted scores for pain (38.7 vs. 44.2, p<0.01) and fatigue (39.6 vs. 45.2, p=0.01).

CONCLUSION

In a representative sample of women with SLE, obesity (by FMI and BMI) independently associated with worse patient reported outcomes, including disease activity, depressive symptoms, and symptoms of pain and fatigue. Obesity may represent a modifiable target for improving outcomes in this patient population. This article is protected by copyright. All rights reserved.

Cancer therapeutics-related cardiac dysfunction (CTRCD) is a well-established adverse effect resulting from a number of cancer therapeutics. Newer immunotherapy has been associated with cardiomyopathy and myocarditis making comprehensive imaging useful for early recognition. Cardiac MRI (CMR) offers a comprehensive evaluation to detect CTRCD. Established guidelines for monitoring left ventricular ejection fraction for potential cardiotoxicity have recently incorporated CMR. We will review the utility of CMR in contemporary evaluation for potential oncologic cardiotoxicity.

AIMS

The efficacy of patent foramen ovale (PFO) closure for cryptogenic stroke has been controversial. We undertook a meta-analysis of randomized controlled trials (RCTs) comparing device closure with medical therapy to prevent recurrent stroke for patients with PFO.

METHODS AND RESULTS

We systematically identified all RCTs comparing device closure to medical therapy for cryptogenic stroke in patients with PFO. The primary efficacy endpoint was recurrent stroke, analysed on an intention-to-treat basis. The primary safety endpoint was new onset atrial fibrillation (AF). Five studies (3440 patients) were included. In all, 1829 patients were randomized to device closure and 1611 to medical therapy. Across all patients, PFO closure was superior to medical therapy for prevention of stroke [hazard ratio (HR) 0.32, 95% confidence interval (95% CI) 0.13-0.82; P = 0.018, I2 = 73.4%]. The risk of AF was significantly increased with device closure [risk ratio (RR) 4.68, 95% CI 2.19-10.00, P<0.001, heterogeneity I2 = 27.5%)]. In patients with large shunts, PFO closure was associated with a significant reduction in stroke (HR 0.33, 95% CI 0.16-0.72; P = 0.005), whilst there was no significant reduction in stroke in patients with a small shunt (HR 0.90, 95% CI 0.50-1.60; P = 0.712). There was no effect from the presence or absence of an atrial septal aneurysm on outcomes (P = 0.994).

CONCLUSION

In selected patients with cryptogenic stroke, PFO closure is superior to medical therapy for the prevention of further stroke: this is particularly true for patients with moderate-to-large shunts. Guidelines should be updated to reflect this.
