Dataset related to article "Imaging Correlates between Headache and Breast Cancer: An [18F]FDG PET Study"
<p>This record contains raw data related to article "Imaging Correlates between Headache and Breast Cancer: An [18F]FDG PET Study"</p><p><strong>Abstract</strong></p><p>This study aimed to examine brain metabolic patterns on [18F]Fluorodeoxyglucose ([18F]FDG) positron emission tomography (PET) in breast cancer (BC), comparing patients with tension-type headache (TTH), migraine (MiG), and those without headache. Further association with BC response to neoadjuvant chemotherapy (NAC) was explored. In this prospective study, BC patients eligible for NAC performed total-body [18F]FDG PET/CT with a dedicated brain scan. A voxel-wise analysis (two-sample <i>t</i>-test) and a multiple regression model were used to compare brain metabolic patterns among TTH, MiG, and no-headache patients and to correlate them with clinical covariates. A single-subject analysis compared each patient's brain uptake before and after NAC with a healthy control group. Primary headache was diagnosed in 39/46 of BC patients (39% TTH and 46% MiG). TTH patients exhibited hypometabolism in specific brain regions before NAC. TTH patients with a pathological complete response (pCR) to NAC showed hypermetabolic brain regions in the anterior medial frontal cortex. The correlation between tumor uptake and brain metabolism varied before and after NAC, suggesting an inverse relationship. Additionally, the single-subject analysis revealed that hypometabolic brain regions were not present after NAC. Primary headache, especially MiG, was associated with a better response to NAC. These findings suggest complex interactions between BC, headache, and hormonal status, warranting further investigation in larger prospective cohorts.</p>

Prognostic value of left atrial strain quantification from 2D ultrasound imaging in post-ischemic heart failure patients: evidence from the REMODEL-HF study.
<p>Frigelli M, Sturla F, Milani V, Ramputi L, Citarella M, Menicanti L, Votta E, Castelvecchio S. Prognostic value of left atrial strain quantification from 2D ultrasound imaging in post-ischemic heart failure patients: evidence from the REMODEL-HF study. Int J Cardiol. 2022 Sep 1;362:183-189. doi: 10.1016/j.ijcard.2022.04.071. Epub 2022 Apr 30. PMID: 35504452.</p> <p>Abstract</p> <p><strong>Background: </strong>Left atrial (LA) function can be effectively assessed by measuring longitudinal LA strain (LAS) via two-dimensional speckle tracking echocardiography (2DSTE). Here, we test 2DSTE-based LAS as marker of different left ventricle (LV) remodeling patterns and as prognostic index in ischemic heart failure (HF) candidates to surgical ventricular reconstruction.</p> <p><strong>Methods: </strong>We retrospectively considered ischemic HF patients with anterior (group A, n=130) or posterior (group P, n=48) LV remodeling. Based on 2D ultrasound, LV and LA morpho-functional parameters were quantified including reservoir (LAS<sub>Res</sub>), conduit (LAS<sub>Cond</sub>) and booster (LAS<sub>Boost</sub>) LAS. We tested their capability to discriminate between groups A and P, and their group-specific prognostic significance for the composite end-point of death or HF re-hospitalization at follow-up (mean follow-up time=40 months, range 3-101 months).</p> <p><strong>Results: </strong>Group A and group P displayed similar end-diastolic (p=0.89) and end-systolic (p=0.33) LV volume index, and LA volume index LAVi (p=0.44) corrected for the degree of mitral regurgitation. As compared to group P, group A revealed a significant reduction in LAS<sub>Boost</sub> (9.2±0.4% vs. 11.1±0.7%, p=0.04) and a non-significant reduction in LAS<sub>Res</sub> (16.9±0.7% vs. 19.3±1.1%, p=0.06). Kaplan-Meier curves showed that the median LAS<sub>Res</sub> and LAS<sub>Boost</sub> values effectively stratified patients based on their prognosis in the overall study population (Log-rank p=0.002 and Log_rank p<0.0001) and in group A, where the association was stronger for LAS<sub>Boost</sub> (Log-rank p<0.001) than for LAS<sub>Res</sub> (Log-rank p=0.013).</p> <p><strong>Conclusions: </strong>2DSTE-based LAS assessment is affordable, repeatable and non-invasive, and could add clinically-relevant mechanistic insight and prognostic value in the stratification of ischemic HF patients.</p>
