Arizona ash (Fraxinus velutina Torr.) seedlings were grown in 0.21-L plastic liner containers, half treated with 100 g Cu(OH)2/L latex carrier (formulated as Spin Out), and half nontreated. Seedlings were sequentially transplanted to larger containers, from liners to 2.5-L black plastic containers then to 11.8-L containers resulting in a 2 × 2 × 2 factorial combination of container sizes and Cu-treatments (eight combinations with 30 replicates/treatment). Nursery conditions and production procedures were determined from regional nurseries using a modified Delphi technique. Growth responses (height, caliper, market grade) and costs of production were determined for each treatment combination through marketable size in 11.8-L containers. Significant interactions (P ≤ 0.05) among liner and 2.5-L container treatments occurred for end of season trunk diameter and market ratings. Those seedlings grown in both Cu-treated liners and 2.5-L containers tended to have larger calipers and market ratings than other treatment combinations. Growth increases were not realized when containers were treated at a single stage. Copper-treated containers resulted in a 17-second labor savings per container at transplant from 2.5- to 11.8-L containers. Labor requirements were not significantly (P ≤ 0.05) different among treatments at transplant from 0.21- to 2.5-L containers.

Five species of trees, Fraxinus velutina Torr., Pistacia chinensis Bunge, Platanus occidentalis L., Quercus virginiana Mill., and Ulmus parvifolia Jacq., were first grown in 0.45-L conventional black plastic liner containers, then transplanted to 25-L black plastic containers and grown to a marketable size. The same species were grown in similar-size, open-bottom, air-root pruning, cylindrical, aluminum (Accelerator) containers filled with the equal volumes of media. Plant growth characteristics, root-zone temperatures, and media moisture status were measured. Growth of Q. virginiana was reduced in Accelerator liner containers compared to conventional black plastic liners. Accelerator liners did eliminate circling and deflection of roots at the bottom of the liner containers. Growth of U. parvifolia, F. velutina, and Q. virginiana were similar in the larger 25-L Accelerator and black plastic containers, while growth of P. chinensis and P. occidentalis were greater in Accelerator containers than in conventional black plastic containers. Root-zone temperatures, particularly at the periphery of the rootball, were significantly reduced on warm days in Accelerator containers compared to those in black plastic containers. Media in Accelerator containers were slightly drier than that in black plastic containers.

ObjectiveTo delineate a comprehensive curriculum for fellowship training in neuroinfectious diseases, we conducted a modified Delphi approach to reach consensus among 11 experts in the field.MethodsThe authors invited a diverse range of experts from the American Academy of Neurology Neuro-Infectious Diseases (AAN Neuro-ID) Section to participate in a consensus process using a modified Delphi technique.ResultsA comprehensive list of topics was generated with 101 initial items. Through 3 rounds of voting and discussion, a curriculum with 83 items reached consensus.ConclusionsThe modified Delphi technique provides an efficient and rigorous means to reach consensus on topics requiring expert opinion. The AAN Neuro-ID section provided the pool of diverse experts, the infrastructure, and the community through which to accomplish the consensus project successfully. This process could be applied to other subspecialties and sections at the AAN.

Modified Delphi Technique

Introduction Across the United Kingdom, physiotherapy for critical care patients is provided 24 h a day, 7 days per week. There is a national drive to standardise the knowledge and skills of physiotherapists which will support training and reduce variability in clinical practice. Methods A modified Delphi technique using a questionnaire was used. The questionnaire, originally containing 214 items, was completed over three rounds. Items with no consensus were included in later rounds along with any additional items suggested. Results In all, 114 physiotherapists from across the United Kingdom participated in the first round, with 102 and 92 completing rounds 2 and 3, respectively. In total, 224 items were included: 107 were deemed essential as a minimum standard of clinical practice; 83 were not essential and consensus was not reached for 34 items. Analysis/Conclusion This study identified 107 items of knowledge and skills that are essential as a minimum standard for clinical practice by physiotherapists working in United Kingdom critical care units.

ObjectiveTo determine the stage of training at which neurology residents should achieve individual elements of the Accreditation Council for Graduate Medical Education neurology Milestones and to examine the relationship between perceived importance of Milestones and the stage by which they should be achieved.MethodsA modified Delphi technique was used to establish consensus postgraduate year (PGY) expectations for neurology Milestone competencies across 3 geographically and administratively distinct Mayo Clinic neurology residency programs. Timing expectations were examined for relationships to perceived importance of the individual Milestones and effects of participant characteristics.ResultsPGY expectations for neurology Milestone elements ranged from PGY 1.3 to PGY 4.1. Extent of rater educational seniority had no effect on PGY competency expectations. There was a moderate inverse relationship between perceived importance of the Milestone element and the PGY by which it should be achieved (rs = −0.74, p < 0.0001).Conclusions and relevanceExpectations for neurology Milestone competency acquisition can be measured and may help inform individual program design, educational expectations, and future Milestone design.

Abstract The number of articles related to antimicrobial stewardship published each year has increased significantly over the last decade. Keeping up with the literature, particularly the most innovative, well-designed, or applicable to one’s own practice area, can be challenging. The Southeastern Research Group Endeavor (SERGE-45) network reviewed antimicrobial stewardship-related, peer-reviewed literature from 2020 that detailed actionable interventions. The top 13 publications were summarized following identification using a modified Delphi technique. This article highlights the selected interventions and may serve as a key resource for teaching and training, and to identify novel or optimized stewardship opportunities within one’s institution.
