STUDY DESIGN/METHODS:Cross-sectional survey. OBJECTIVE:Surgical treatment of degenerative lumbar spondylolisthesis is remarkably varied due to heterogeneity of clinical-radiological presentations. This study aimed to assess which spinopelvic radiological parameters were considered for decision-making. METHODS:Survey distributed to International AO Spine members to analyze surgeons' considerations for treatment. Data collected includes demographics, training background, years of experience, and treatment decisions based on various radiographical findings, including segmental and global spinopelvic parameters. RESULTS:= 0.043), respectively. Additionally, the surgeons' age was associated with using angular motion on flexion-extension radiographs, and volume of treated cases yearly with consideration for disc height. CONCLUSIONS:Treatment of degenerative lumbar spondylolisthesis was influenced by slippage on dynamic radiographs, disc height, global alignment, and PI-LL mismatch. Surgeons' age and Region, fellowship-trained, and volume of treated cases were significantly associated to apply these radiological parameters.

Although ethics is increasingly integrated in the curriculum of U.S. medical schools, it remains not well integrated with system issues, and social and structural contexts of illness. Moreover, ethical analysis is not often taught as a clinical skill. To address these issues, an outcomes driven course in Social Sciences, Humanities, Ethics and Professionalism (SHEP) was created. Within the course, a web-based concept mapping device, SHEP Case Analysis Tool (SCAT), was created which schematizes the structure and flow of clinical cases from diagnosis to treatment options, to shared decision making to outcome, and includes key stakeholders, influences, and structural features of the health system. In the course, each student analyzes a case in which they were directly involved using SCAT and presents their analysis to faculty and peers. This exercise 1) reinforces knowledge-based portions of the course pedagogy, 2) supports meta-cognition and critical thinking through concept mapping, 3) applies multidimensional analysis to identify ethical, social, and system issues that impact patient-care. 4) develops problem solving skills, 5) counters the hidden curriculum/support professional identity formation, and 6) develops skills in reflective discourse. This paper outlines the development and use of this concept mapping case analysis tool in an undergraduate medical education curriculum.

The 2022 American Society of Metabolic and Bariatric Surgery (ASMBS) and International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) updated the indications for Metabolic and Bariatric Surgery (MBS), replacing the previous guidelines established by the NIH over 30 years ago. The evidence supporting these updated guidelines has been strengthened to assist metabolic and bariatric surgeons, nutritionists, and other members of multidisciplinary teams, as well as patients. This study aims to assess the level of evidence and the strength of recommendations compared to the previously published criteria.

BACKGROUND:In response to the COVID-19 pandemic, the US Congress authorized the US Department of Agriculture to waive a variety of school meal regulations and funded school meals daily for all students at no charge regardless of family income. Because federal Universal Free School Meals (UFSM) ended with the 2021-2022 school year, several states, including California and Maine, adopted state-level UFSM policies. OBJECTIVE:This study aimed to understand parent perceptions of school meals and the federal and new state UFSM policies in California and Maine, including potential challenges and benefits to students and households. DESIGN/METHODS:A mixed methods study design was used. A quantitative cross-sectional survey was administered, and semi-structured interviews were conducted in English and Spanish during the 2021-2022 school year. PARTICIPANTS/SETTING/METHODS:The quantitative survey was administered to parents of students in elementary, middle, and high schools in rural, suburban, and urban communities in California (n = 1110) and Maine (n = 80). Qualitative interviews were then conducted with a subset of these parents in California (n = 46) and Maine (n = 20) using Zoom (Zoom Video Communications). Most survey participants (708 of 1190 [59.5%]) and interviewees (40 of 66 [60.6%]) were parents of students who were eligible for free or reduced-price meals. MAIN OUTCOME MEASURES/METHODS:Parents' perceptions of UFSM, school meal quality, and experiences applying for free or reduced-price meals were examined. ANALYSES PERFORMED/UNASSIGNED:Tests of proportions were used to analyze survey data. Using grounded theory, interview transcripts were analyzed qualitatively by 2 trained research assistants, applying principles of content analysis to identify themes and domains. Inter-rater reliability was conducted. RESULTS:Parents perceived that school meals and UFSM saved families money and time, as parents had fewer meals to purchase and prepare for their children. In addition, UFSM reduced parents' stress and reduced stigma for children and for parents, who described feelings of embarrassment when they previously filled out paperwork for free or reduced-price meals. Although parent perceptions of school meal quality and healthfulness were mixed, most parents reported feeling grateful for school meals. CONCLUSIONS:Parents had mixed opinions on the quality and healthfulness of school meals, but believed UFSM saved them money and time and reduced their stress. Parents also felt UFSM reduced stigma for families.

Prospective memory (PM) impairment is a common consequence of moderate-severe traumatic brain injury (TBI). Compensatory strategy training and rehabilitation (COMP) is the usual treatment of PM deficits through environmental modification and the use of assistive methods such as diaries and routines. The study intends to examine the changes in white matter integrity, as measured by advanced diffusion magnetic resonance imaging (dMRI) following COMP intervention in moderate-severe TBI patients. Nine COMP intervention and twelve routine care comparison cohort moderate-severe TBI patients were recruited from level 1 trauma centres in the Brisbane metropolitan area. Both groups were imaged at least one-month post-TBI for a baseline scan. COMP group was imaged again after a 6-week COMP intervention program and the comparison group was imaged again at least 6 weeks after the baseline scan. MRI scan included structural imaging and dMRI, which the latter fitted for the Neurite Orientation Dispersion and Density Imaging (NODDI) model. Only the comparison group had decreased Neurite Density Index in the major white matter tracts and increased isotropic diffusion in the fluid space between the cortical folds. Our results indicated that COMP intervention slowed down the neural degeneration in moderate-severe TBI patients as compared to routine medical care/rehabilitation.

INTRODUCTION AND PROBLEM STATEMENT/UNASSIGNED:Neurologic disease is a leading cause of disability and death worldwide. As the global population ages, the burden of these diseases is expected to increase. Despite this increased clinical need, neurology trainees are seldom taught skills and concepts in palliative care. Education in Palliative and End-of-Life Care for Neurology (EPEC-N) is a publicly available neuropalliative care curriculum designed to be taught by both palliative care specialists and nonspecialists alike. OBJECTIVES/UNASSIGNED:(1) To create a feasible curriculum in neuropalliative care using EPEC-N, (2) to improve learners' satisfaction with neuropalliative care training, and (3) to improve learners' confidence with neuropalliative care topics. METHODS AND CURRICULUM DESCRIPTION/UNASSIGNED:Three academic centers implemented a neuropalliative care curriculum for neurology residents using EPEC-N modules. Each site selected 4 of the 26 topics. Instructor backgrounds varied by site and included neurology senior residents, fellows, and faculty; none had completed palliative care fellowship at the time of teaching. Teaching methods included lecture, case discussion, and role-play. To assess feasibility and acceptability of this curriculum, learners, instructors, and site leads completed postsession surveys. RESULTS AND ASSESSMENT DATA/UNASSIGNED:A total of 87 residents attended at least 1 didactic session, and 23 residents completed the evaluation survey. All 3 sites were able to successfully implement an evidence-based and subspecialist-approved neuropalliative care curriculum without relying on subspecialty instruction, despite variations in instructor background, curriculum format, and module selection. Learners overall expressed a positive experience with this curriculum, with most of the respondents indicating that each session was effective in improving their knowledge base, relevant to current practice, and provided in an effective teaching format. Site leads and instructors found the curriculum easy to use, in minimal need of modification, and helpful for delivering neuropalliative care education. DISCUSSION AND LESSONS LEARNED/UNASSIGNED:The EPEC-N curriculum was successfully implemented at 3 US sites, demonstrating feasibility, acceptability, and adaptability across institutions. Further research is needed to evaluate the effectiveness of this curriculum in improving neuropalliative care skills for neurologists and raising the standard of primary neuropalliative care.

PURPOSE/OBJECTIVE:The purpose of this study was to characterize the morphological and immunological aspects of biointegration at the optic-cornea joint of a second-generation synthetic corneal device. METHODS:The initial prototype, single-piece optic-skirt configuration, is constructed from compact and flexible perfluoroalkoxy alkane with porous expanded polytetrafluoroethylene (ePTFE) overlying the skirt to allow skirt-cornea biointegration. The second-generation version was modified to add ePTFE around the optic wall to allow optic-cornea biointegration. Initial and amended second-generation devices were implanted into healthy rabbit eyes. Clinical examination, anterior segment optical coherence tomography, light microscopy, and immunofluorescence studies were performed to assess structural integrity and determine molecular signatures indicative of inflammation and tissue remodeling between the 2 prototypes. RESULTS:Recipient eyes with both device versions showed no epithelial defects or tissue retraction at 3 months postoperatively. Optical coherence tomography images demonstrated no appreciable perioptic space with either prototype. Histopathology of the initial device demonstrated lack of stromal adhesion at the optic-cornea joint with epithelium filling the perioptic space. Second-generation devices demonstrated full sealing of the recipient stroma along the optic stem. Although the routine histopathology did not demonstrate inflammatory cells in the recipient cornea with either device, immunohistochemistry stains demonstrated quiescent phenotype of stromal and epithelial cells only in the second-generation devices. CONCLUSIONS:Biointegration between the synthetic corneal device and recipient tissue at the optic-cornea joint seems to avert inflammation and may help prevent sterile tissue lysis and prolong retention.

Fibromyalgia (FM) is a complex chronic musculoskeletal pain disorder with an elusive pathogenesis, with a strong implication of immune interactions. We recently found that IL-5 and the adaptive immune system mediates pain outcomes in fibromyalgia (FM) patients and preclinical models of FM-like chronic widespread pain (CWP). However, there is an active debate if FM/CWP has an autoimmune etiology. Preclinical models of CWP utilize a repeated insult paradigm, which resembles a primary, then secondary response similarly observed in the antibody response, in which the subsequent event causes a potentiated pain response. Recent translational studies have implicated immunoglobulins (Ig) and B-cells in FM/CWP pathophysiology. To understand if these are involved in preclinical models of CWP, we performed comprehensive B-cell phenotyping in the bone marrow, circulation, and popliteal (draining) lymph nodes in the two-hit acidic saline model of CWP. We found increased MHC class II-expressing B-cells in peripheral blood, increased activated plasma cells in peripheral blood, and increased memory B-cells in the bone marrow. Interestingly, acidic pH (4.0) injected mice have reduced levels of IgG1, independent of treatment with IL-5. We have demonstrated that the acidic saline model of CWP induces T-cell mediated activation of B-cells, increased active plasma cells, and increased memory B-cells in female mice.

BACKGROUND:by Philips Healthcare). A multi-specialty group of physician POCUS experts (n = 35) acquired three standard ultrasound views (abdominal right upper quadrant, cardiac apical 4-chamber, and superficial neck and lung views) in random order on the same standardized patients and rated the image quality. Afterward, a final survey of the overall ease of use, image quality, and satisfaction of each handheld was completed. RESULTS:. The 5 most desirable characteristics of handhelds were image quality, ease of use, portability, probe size, and battery life. Ultimately, all 6 handhelds had notable advantages and disadvantages, with no single device having all desired qualities or features. CONCLUSIONS:was rated highest for overall ease of use and was the most preferred handheld for purchase by POCUS experts.
