Context: Early palliative care can improve end-of-life outcomes, but referrals to palliative care specialists can be delayed in the primary care setting. Objective: This pilot study assessed the effect of a machine-learning algorithm on time to palliative care in a primary care population. Methods: Patients (aged ≥18 years) were eligible if they were empaneled with a primary care provider (PCP) from July 20, 2020, through May 30, 2021. The algorithm evaluated their health records and presented patients who were predicted to have the greatest need for palliative care. Records were then reviewed by palliative care specialists, and patients were randomized in a stepped-wedge fashion to have a referral notification sent to their PCPs if unmet palliative care needs were verified. Time-to-event outcomes were evaluated with Poisson regression models. Results: Of the 127,080 patients evaluated, 934 had their health records presented for review. Some patients were repeatedly presented by the algorithm (total presentations: 1592). In the intervention arm, PCPs were prompted to order a palliative care consultation for 142 patients. The time to 0.1% of the population receiving a palliative care consultation was 60.9 days for the intervention arm versus 71.8 days for the control arm (probability of a shorter time with the intervention, 0.88). Conclusion: A machine-learning algorithm to identify palliative care needs was successfully integrated into a primary care practice. More work is needed to improve the workflow.

Abstract Background Climate-related stressors such as heat, wildfires, and extreme weather are increasingly recognized as determinants of cardiovascular and oncologic health. However, their joint impact on overlapping cancer–cardiovascular disease (CVD) burdens remains unknown. We developed a Cardio-Oncology Burden Index (COBI) to quantify the co-prevalence of cancer and CVD at the community level and examined its association with climate vulnerability across U.S. census tracts. Methods We conducted a cross-sectional ecological analysis of 82,679 census tracts (328,683,841 residents) using the CDC PLACES database. COBI was derived using principal component analysis of age-adjusted prevalence of cancer, coronary artery disease, and stroke. The Climate Burden Index (CBI, 0–1 percentile) integrates multiple climate-related exposures, including extreme temperature, wildfire frequency, and severe weather events. Population-weighted mixed-effects regression models with county-level random effects estimated associations between CBI and COBI, adjusting for region, rurality, and environmental justice indicators. β coefficients represent percentage-point differences in COBI per unit (or category) increase in climate burden. Exposure–response relationships were examined using restricted cubic splines (RCS). Robustness was assessed via geographically matched (<50 km) and fully matched (region, rural–urban commuting area, and environmental justice) analyses. Results Marked spatial heterogeneity was observed in both CBI and COBI across the U.S. (Fig. A–B). Higher climate burden was consistently associated with greater cardio-oncology burden (Fig. C), demonstrating a dose–response relationship: second vs lowest quartile β=0.92 (95% CI, 0.61–1.24); third vs lowest quartile β=1.61 (95% CI, 1.30–1.92); highest vs lowest quartile β=3.44 (95% CI, 3.11–3.76). The RCS model revealed a significant non-linear association (p_non-linear<0.001), with a plateau at moderate exposures and a steep rise at the highest CBI levels (Fig. D). Results remained robust in sensitivity analyses (β=4.17 [95% CI, 3.62–4.71] for geographically matched; β=4.39 [95% CI, 4.10–4.69] for fully matched tracts; Table). Conclusions Greater climate burden is independently associated with higher cardio-oncology burden across U.S. communities, with disproportionate effects in the most climate-vulnerable areas. This novel, population-level linkage between climate stress and onco-cardiovascular disease burden, highlights an emerging syndemic at the intersection of environment, cancer, and CVD. Targeted mitigation and prevention strategies integrating environmental resilience into chronic disease prevention are urgently needed.For image description, please refer to the figure legend and surrounding text.

Background Anomalous aortic origin of the right coronary artery (AAORCA) with an intramural course is a rare but potentially life-threatening anomaly due to its association with exertional ischemia and sudden cardiac death. Surgical correction aims to eliminate the ischemic mechanism. This study reports a single-center experience with adult patients who underwent right coronary artery (RCA) reimplantation for AAORCA. Methods A retrospective review was conducted of symptomatic adult patients with AAORCA who underwent RCA reimplantation between June 2017 and August 2024. Baseline clinical features, perioperative outcomes, and follow-up data were assessed. Results Forty patients (85% [34/40] male; median age 44 years) were included. The most common presenting symptom was exertional chest pain (82.5%, [33/40]), followed by dyspnea (45%, [18/40]) and syncope or presyncope (30%, [12/40]). Coronary computed tomography angiography (CCTA) was performed to diagnose the high-risk coronary features. All patients underwent RCA reimplantation into the right sinus of Valsalva. One patient also received a saphenous-vein graft to the distal-RCA. There was no in-hospital or follow-up mortality. At a mean follow-up of 30.3 ± 20.5 months, 8/40 patients (20%) reported recurrent symptoms, including chest pain (10%, [4/40]), dyspnea on exertion (5%, [2/40]), and palpitation (5%, [2/40]). Surveillance CCTA or invasive angiography performed in 14 patients, including 8 symptomatic patients, confirmed the widely patent RCA with no ostial stenosis or kinking. Post operative exercise testing in all these patients was negative. Conclusions In adults with AAORCA and an intramural or interarterial course; reimplantation of the RCA into the right-sinus of Valsalva achieves excellent early- to midterm outcomes, with low mortality, symptom resolution, and durable coronary patency.

ABSTRACT Research is important to advance the field of emergency medicine and improve patient care. As such, emergency medicine residents are required to complete a scholarly project during their training. This experience provides an opportunity to enhance their exposure to research, expanding their skillset as both producers and consumers of the medical literature. However, the process may be overwhelming to launch, especially for residents. This Educator's Blueprint will provide 10 strategies for navigating and optimizing the resident research experience. These strategies include providing structured training, creating a research‐supportive environment, selecting a project using resident‐centric FINER criteria, identifying a research mentor, creating mosaic research experiences, setting expectations, empowering residents, selecting team members for sustainability, providing scaffolding and support during the writing stage, and explaining the peer review process and normalizing rejection or revisions. These strategies will help guide faculty seeking to enhance their learners' research experience.

ABSTRACT Traumatic defects of the helical rim caused by human bites present significant reconstructive challenges because of tissue loss, infection risk, and the need to preserve auricular contour and symmetry. We report a 27‐year‐old man who presented with a middle‐third defect of the left helical rim following necrosis of an initially sutured avulsed flap caused by a human bite injury. After discussion of reconstructive options, including chondrocutaneous advancement and staged flap procedures, a single‐stage modified postauricular flap without skin grafting was selected to preserve ear size and minimize donor‐site morbidity. The flap was successfully inset with restoration of the helical contour, and postoperative follow‐up demonstrated stable healing, preserved auricular shape, and high patient satisfaction without complications. This case highlights that a single‐stage modified postauricular flap is a reliable and patient‐centered option for reconstruction of traumatic helical rim defects following human bite injuries.
