Article Abstract

Conventional echocardiographic (ECHO) parameters of systolic and diastolic function of the left ventricular (LV) have been shown to be load dependent. However, the impact of pre-load reduction on tissue Doppler (TD) parameters of LV function is incompletely understood. To evaluate the effect of a single hemodialysis (HD) session on LV systolic and diastolic function using pulsed Doppler echocardiography and pulsed tissue Doppler imaging (TDI), we studied 81 chronic HD patients (40 males; mean age 52.4 ± 16.4 years) with these tools. ECHO parameters were obtained 30 min before and 30 min after HD. Fluid volume removed by HD was 1640 ± 730 cm³. HD led to reduction in LV end-diastolic volume (P <0.001), end-systolic volume (P <0.001), left atrium area (P <0.001), peak early (E-wave) trans-mitral flow velocity (P <0.001), the ratio of early to late Doppler velocities of diastolic mitral inflow (P <0.001) and aortic time velocity integral (P <0.001). No significant change in peak S velocity of pulmonary vein flow after HD was noted. Early and late diastolic (E') TDI velocities and the ratio of early to late TDI diastolic velocities (E'/A') on the lateral side of the mitral annulus decreased significantly after HD (P = 0.013; P = 0.007 and P = 0.008, respectively). Velocity of flow progression (Vp) during diastole was not affected by pre-load reduction. Pulmonary artery systolic pressure and the diameter of the inferior vena cava decreased significantly (P <0.001 and P <0.001, respectively) after HD. We conclude that most of the Doppler-derived indices of diastolic function are pre-load-dependent and velocity of flow progression was minimally affected by pre-load reduction in HD patients.

Background: In obstructive hypertrophic cardiomyopathy, myectomy improves symptoms, quality of life, and left ventricular (LV) outflow tract gradients. We prospectively evaluated the temporal changes in various echo parameters after myectomy.

Methods And Results: In 173 adults with obstructive hypertrophic cardiomyopathy (53±10 years, 63% men) who underwent myectomy between March 2017 and June 2020, clinical and blinded echo assessment (before and at 12±6 months follow-up) was performed prospectively (SPIRIT-HCM [Quality of Life and Functional Capacity Following Septal Myectomy in Obstructive Patients With Hypertrophic Cardiomyopathy]).

Introduction: Congenital and acquired damage to hypothalamic nuclei or neuronal circuits controlling satiety and energy expenditure results in hypothalamic obesity (HO). To date, successful weight loss and satiety has only been achieved in a limited number of affected patients across multiple drug trials. Glucagon-like peptide-1 (GLP-1) acts via central pathways that are independent from the hypothalamus to induce satiety.

The operation of modern free-electron lasers (FELs) necessitates precise knowledge of electron beam properties at the undulator to ensure the level of control required by increasingly demanding experiments. In seeded FELs, where only electrons interacting with the seed laser contribute to the process, it is crucial to determine the local values of these properties. We present a novel method, based on accurate modeling of the FEL process in high-gain harmonic generation, to accurately retrieve the electron beam slice energy spread, current and laser-induced energy modulation.

Background: Currently, the activity of juvenile dermatomyositis (JDM) is mainly assessed based on clinical manifestations, creatine kinase (CK) level, and magnetic resonance imaging (MRI), but certain limitations arise in these approaches for children. Thus, this cross-sectional study aimed to explore the value of ultrasound in evaluating muscle inflammation via the dynamic analysis of muscle ultrasound characteristics in children with active or stable JDM.

Methods: The data of a group of children who were diagnosed with JDM and admitted to the Rheumatology and Immunology Department of the Capital Pediatric Research Institute Children's Hospital between June 2022 and November 2023, and a normal control group were collected.

Background: Traditional echo-planar imaging with intravoxel incoherent motion (EPI-IVIM) exhibits significant magnetic susceptibility artifacts and geometric distortions, which limits its application in nasopharyngeal carcinoma (NPC). This study aimed to compare the qualitative and quantitative indicators between turbo spin echo with intravoxel incoherent motion (TSE-IVIM) and EPI-IVIM in patients with NPC and to provide optimal scanning strategies based on the relationships among these indicators.

Methods: A cross-sectional study was conducted between March 2022 and August 2022.
