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.

Objective: A recent randomized trial of a group psychosocial telehealth intervention (STRIDE) improved anxiety, depression, quality of life (QOL), symptom distress, coping, and self-efficacy to manage symptoms related to taking adjuvant endocrine therapy (AET) in women with non-metastatic hormone receptor-positive breast cancer. This study examined whether changes in coping and self-efficacy mediated intervention effects on anxiety, depression, QOL, and symptom distress.

Method: Women (N = 100) were recruited between 10/2019-06/2021 from Massachusetts General Hospital and were randomized to STRIDE or to the medication monitoring control group.

Hematopoietic stem cell transplant (HSCT) survivors frequently experience persistent sexual dysfunction, which is associated with impaired quality of life and increased psychological distress. The lack of availability of clinicians with expertise in sexual health limits the capacity to address sexual health concerns in HSCT survivors. Digital health applications may offer a patient-centered and scalable solution to address sexual health concerns in cancer survivors.

Article Synopsis
  • The study investigates the impact of a group cognitive behavioral intervention (STRIDE) on adherence to adjuvant endocrine therapy (AET) in hormone-sensitive breast cancer patients who report medication-related distress.
  • With 100 participants, the results indicate that STRIDE significantly improved adherence rates over time for those encountering difficulties with AET and having strong expectations for its benefits compared to a control group.
  • The findings suggest that discussions led by clinicians addressing patient perceptions about AET can enhance adherence to treatment, indicating that tailored behavioral interventions could be beneficial.

Early palliative care, palliative care integrated with oncology care early in the course of illness, has myriad benefits for patients and their caregivers, including improved quality of life, reduced physical and psychological symptom burden, enhanced prognostic awareness, and reduced health care utilization at the end of life. Although ASCO and others recommend early palliative care for all patients with advanced cancer, widespread implementation of early palliative care has not been realized because of barriers such as insufficient reimbursement and a palliative care workforce shortage. Investigators have recently tested several implementation strategies to overcome these barriers, including triggers for palliative care consultations, telehealth delivery, navigator-delivered interventions, and primary palliative care interventions.
