Purpose: Chronic graft-versus-host-disease (cGVHD), an inflammatory condition affecting allogeneic hematopoietic cell transplantation (HCT) survivors, is associated with a range of debilitating physical and psychological sequela. Yet HCT recipients with cGVHD are virtually absent from survivorship intervention research. We conducted a randomized clinical trial to evaluate the feasibility and preliminary efficacy of a multidisciplinary group coping skills intervention (Horizons) tailored to meet these patients' unique needs.

Harmonizing and validating Xe gas exchange imaging across multiple sites is hampered by a lack of a quantitative standard that 1) displays the unique spectral properties of Xe observed from human subjects in vivo and 2) has short enough T times to enable practical imaging. This work describes and demonstrates the development of two dissolved-phase, thermally polarized phantoms that mimic the in-vivo, red blood cell and membrane resonances of Xe dissolved in human lungs. Following optimization, combinations of two common organic solvents, acetone and dimethyl sulfoxide, resulted in two in-vivo-like dissolved-phase Xe phantoms yielding chemical shifts of 212.

Background And Objectives: Neuroblastoma, the most common extracranial solid tumor in children, is rare in adults. This study compares patient characteristics, disease patterns, and treatments among adults, adolescents, and children with neuroblastoma.

Methods: We queried the National Cancer Database (2004-2019) for neuroblastoma cases.

Individual ion mass spectrometry (IMS) is the Orbitrap-based extension of the niche mass spectrometry technique known as charge detection mass spectrometry (CDMS). While traditional CDMS analysis is performed on in-house-built instruments such as the electrostatic linear ion trap, IMS extends CDMS analysis to Orbitrap analyzers, allowing charge detection analysis to be available to the scientific community at large. IMS simultaneously measures the mass-to-charge ratios (m/z) and charges (z) of hundreds to thousands of individual ions within one acquisition event, creating a spectral output directly into the mass domain without the need for further spectral deconvolution.
