Process intensification of element extraction using centrifugal contactors in the nuclear fuel cycle.

This review focuses on consolidating solvent extraction performed in the process intensification equipment known as Centrifugal Contactors (CCs), implemented in Spent Nuclear Fuel (SNF) reprocessing and radioactive waste processing. Recovery of valuable actinides is important from sustainability perspectives as it is a source of metals of technological interest from SNF, specifically the recovery of fissile and fertile material, and can also be employed in the processing of Waste Electrical and Electronic Equipment (WEEE). Solvent extraction (also referred to as liquid-liquid extraction, or aqueous separation), is employed in the separation of f-block elements and fission products in SNF. The sequential isolation using different flowsheets has been performed on a range of scales using CCs. However, solids, either present in the feed solution or formed in situ, are always cited as a concern for the operability of CCs, and their extraction efficiencies. This review quantifies the unexpected solid arisings and accumulation during operation in the presence and absence of highly radioactive isotopes from bench to plant scale. The review concludes with techniques implemented for the removal of solids from CCs.

Advancing clinical trials in nursing homes: A proposed roadmap to success.

An effective clinical research effort in nursing homes to address prevention and treatment of COVID-19 faced overwhelming challenges. Under the Health Care Systems Research Network-Older Americans Independence Centers AGING Initiative, a multidisciplinary Stakeholder Advisory Panel was convened to develop recommendations to improve the capability of the clinical research enterprise in US nursing homes. The Panel considered the nursing home as a setting for clinical trials, reviewed the current state of clinical trials in nursing homes, and ultimately developed recommendations for the establishment of a nursing home clinical trials research network that would be centrally supported and administered. This report summarizes the Panel's recommendations, which were developed in alignment with the following core principles: build on available research infrastructure where appropriate; leverage existing productive partnerships of researchers with groups of nursing homes and nursing home corporations; encompass both efficacy and effectiveness clinical trials; be responsive to a broad range of stakeholders including nursing home residents and their care partners; be relevant to an expansive range of clinical and health care delivery research questions; be able to pivot as necessary to changing research priorities and circumstances; create a pathway for industry-sponsored research as appropriate; invest in strategies to increase diversity in study populations and the research workforce; and foster the development of the next generation of nursing home researchers.

Promoting Family Engagement in the ICU: Experience From a National Collaborative of 63 ICUs.

OBJECTIVES: As part of an improvement program targeting ICU, a national collaborative was launched to help hospitals implement patient- and family-centered care engagement initiatives. DESIGN: Ten-month quality improvement collaborative. SETTING: Guided by a national patient and family advisory group, participating teams implemented an individual project including open visitation; integrating families on rounds; establishing a patient and family advisory committee; using patient and family diaries, among others. SUBJECTS: Sixty-three adult and PICU teams from both academic and community hospitals in 34 states participated. INTERVENTIONS: Monthly team calls, quarterly webinars, newsletters, an online eCommunity, and team reporting assignments were used to facilitate project implementation. MEASUREMENTS AND MAIN RESULTS: The Family Satisfaction with Care in the ICU 24 was used to assess family satisfaction. Clinician perceptions were assessed with the Institute for Patient- and Family-Centered Care Self-Assessment Inventory. Thematic analysis was used to explore narrative data captured from team reports of project barriers, facilitators, and the experience of participating in the collaborative. A total of 2,530 family member and 3,999 clinician surveys were completed. Postimplementation, family members reported statistically significant increases in overall family satisfaction, satisfaction with decision-making, and satisfaction with quality of care (Family Satisfaction with Care in the ICU mean score change range 0.83-1.24; p ≤ 0.027). Clinicians reported that opportunities for families to participate as members of the care team increased. Major barriers included lack of buy-in and ability to promote change in the clinical setting, managing the workload of implementation, and funding to support initiatives. CONCLUSIONS: A national collaborative format was useful to assist ICU teams to implement patient- and family-engagement initiatives. Enlisting stakeholder support, engaging unit-based champions, and highlighting benefits of family engagement can help ICU teams to promote family member involvement and engagement.
