Primary Care Clinician Perspectives on Patient Navigation to Improve Postpartum Care for Patients with Low Income.

Background: Birthing individuals experience significant physical and psychosocial transitions during the postpartum period. Despite amplified health needs, many individuals do not successfully transition from obstetric to primary care. Patient navigation provides a patient-centered solution that has been applied to other health care specialties resulting in improved care coordination and patient engagement for populations in greatest need. Our objective was to understand primary care clinician perspectives regarding the role of navigators in improving postpartum care for individuals with low income. Methods: In this qualitative investigation, we conducted focus groups with primary care clinicians from family and internal medicine specialties. Semistructured interview guides addressed clinician perceptions of navigator roles during the postpartum period and recommendations for navigator training. Focus group discussions were digitally recorded, transcribed, and analyzed via a constant comparative method. Results: Twenty-eight primary care clinicians, including 26 physicians and 2 advanced practice registered nurses, participated in 8 focus groups. Participants reported favorable attitudes toward implementation of a postpartum patient navigation program. Themes regarding useful navigation services included streamlining obstetric to primary care transition, enhancing visit effectiveness, creating personalized postpartum care, and providing patient- and clinician-focused education. Recommendations for navigator training included education on basic medical concerns that are common in the postpartum period, health information privacy and electronic health record use, health care systems, and community resources. Clinical Trial Registration number: NCT03922334. Conclusions: Primary care clinicians were highly receptive to the concept of patient navigation as a process to improve health in the postpartum period through enhanced care coordination and improved patient knowledge, engagement, and self-efficacy.

Nanodiamond–Gadolinium(III) Aggregates for Tracking Cancer Growth In Vivo at High Field

The ability to track labeled cancer cells in vivo would allow researchers to study their distribution, growth, and metastatic potential within the intact organism. Magnetic resonance (MR) imaging is invaluable for tracking cancer cells in vivo as it benefits from high spatial resolution and the absence of ionizing radiation. However, many MR contrast agents (CAs) required to label cells either do not significantly accumulate in cells or are not biologically compatible for translational studies. We have developed carbon-based nanodiamond–gadolinium­(III) aggregates (NDG) for MR imaging that demonstrated remarkable properties for cell tracking in vivo. First, NDG had high relaxivity independent of field strength, a finding unprecedented for gadolinium­(III) [Gd­(III)]–nanoparticle conjugates. Second, NDG demonstrated a 300-fold increase in the cellular delivery of Gd­(III) compared to that of clinical Gd­(III) chelates without sacrificing biocompatibility. Further, we were able to monitor the tumor growth of NDG-labeled flank tumors by <i>T</i>₁- and <i>T</i>₂-weighted MR imaging for 26 days in vivo, longer than was reported for other MR CAs or nuclear agents. Finally, by utilizing quantitative maps of relaxation times, we were able to describe tumor morphology and heterogeneity (corroborated by histological analysis), which would not be possible with competing molecular imaging modalities
