[EX Q]: Infarct heterogeneity has been shown to be independently associated with adverse outcomes in previous smaller studies. However, it is unknown whether infarct characterization is an independent predictor of all-cause mortality in patients with advanced ischemic cardiomyopathy, after adjusting for clinical risk factors, severity of ischemic mitral regurgitation, incomplete revascularization, and device therapy.', 'A total of 362 patients with ischemic cardiomyopathy (left ventricular dysfunction with >70% stenosis in 1 epicardial coronary artery) underwent delayed hyperenhancement-magnetic resonance imaging and coronary angiography between 2002 and 2006. Total myocardial scar and peri-infarct (PI) area were measured using various threshold techniques. Multivariate survival analysis (primary end point of all-cause mortality) was conducted. One hundred fifty-seven deaths occurred during a mean 5.4-year follow-up (mean left ventricular ejection fraction, 239%; mean end-systolic volume index, 11348 mL; mean total myocardial scar %, 25.516.0%; mean PI%, 5.72.9%). PI% (=2.07; P<0.001) was an independent predictor of survival, independent of age, end-systolic volume, sex, mitral regurgitation, diabetes mellitus, dyslipidemia, coronary artery disease severity, implantable cardioverter defibrillator, and incomplete revascularization. PI% using 2 to 3 SD technique yielded the highest incremental prognostic power ((2) score 149).

[EX Q]: Reduced levels of free and total insulin-like growth factor 1 (IGF-I) have been observed in type-1 diabetes (T1D) patients. The bioavailability of IGF-I from the circulation to the target cells is controlled by multifunctional IGF-binding proteins (IGFBPs). The aim of this study was to profile serum IGFBPs in T1D and its complications.', 'We measured the IGFBP levels in 3662 patient serum samples from our ongoing Phenome and Genome of Diabetes Autoimmunity (PAGODA) study. IGFBP levels of four different groups of T1D patients (with 0, 1, 2, and 3 complications) were compared with healthy controls.', 'Three serum IGFBPs (IGFBP-1, -2, and -6) are significantly higher in T1D patients, and these alterations are greater in the presence of diabetic complications. IGFBP-3 is lower in patients with diabetic complications. Analyses using quintiles revealed that risk of T1D complications increases with increasing concentrations of IGFBP-2 (fifth quintile ORs: 18-60, p<10(-26)), IGFBP-1 (fifth quintile ORs: 8-20, p<10(-15)), and IGFBP-6 (fifth quintile ORs: 3-148, p<10(-3)). IGFBP-3 has a negative association with T1D complications (fifth quintile ORs: 0.12-0.25, p<10(-5)).

[EX Q]: This study was performed to examine the association between household food insecurity, self-efficacy and infant feeding styles in mothers with children under 2 years old in Varamin, Iran.', "In this cross-sectional study, 423 mothers aged 17-40 years from different areas of Varamin were selected by a multistage sampling methods from October 2013 to February 2014. The questionnaires consisted of three valid instruments, including: Household Food Insecurity Access Scale, Comprehensive Feeding Practices Questionnaire and Mother's Self-Efficacy Questionnaire. Data were analyzed using Chi-square, t tests, ANOVA, Pearson correlations and multiple linear regressions. Structural equation modeling was also used.", "Mild and moderate-severe food insecurity was observed in 39.5 and 12.8 % of the households respectively. Mean score of mother's self-efficacy in food secure households was 32.5 3.7; while in mild food insecure and moderate-severe food insecure households were 31.9 3.1 and 28.4 4.0, respectively (P = 0.001). There was a significant negative correlation between household food insecurity and mother's self-efficacy (r = -0.297, P < 0.01). Significant correlation was seen between mother's self-efficacy and the maternal infant feeding styles. Household food insecurity and mother's self-efficacy had significant relationship with mother-infant feeding styles: control of home food access [ (SE)] = [-0.015(0.004), P = 0.001]; restriction for weight control [ = 0.038(0.013), P = 0.003]; restriction for health [ = 0.019(0.008), P = 0.027] and encouragement [=0.018(0.006), P = 0.001]. The model had sufficient fitness with data of the research (CFI = 0.927, RMSEA = 0.076).
