In 2023, the VAS international working group on Buerger’s Disease (BD) recommended two diagnostic criteria based on a prior Delphi study: “definitive” and “suspected”. The “definitive” criteria are history of smoking, typical angiography, and typical histopathological features. All three features are mandatory to confirm a “definitive” diagnosis of BD. The conundrum is—what features should be considered typical of BD angiography? According to this review, segmental occlusion of infrapopliteal arteries, corkscrew collaterals that appear to continue the occluded arterial segment (Martorell’s sign) or bypass the segmental occlusion, absence of atherosclerotic plaque or aneurysm could differentiate BD from ASO. Hence, for “typical” BD angiography, these manifestations should certainly be considered. However, data for differentiating angiography patterns of BD from the small- and medium-sized vasculitis including Behcet’s disease, scleroderma, hepatitis associated vasculitis, and anti-phospholipid syndrome are limited. Further studies for investigating the angiography pattern in BD patients in early and late presentation of BD, particularly in the patients with long-term follow up, are highly recommended.

Radiation segmentectomy is a dynamic image-guided therapy for hepatic malignancies that uses yttrium 90 transarterial radioembolization to deliver high radiation doses to targeted hepatic segments, achieving high and sustained response rates.

Context.— After-death care can be complicated and time-consuming for clinical staff, and frustrating for bereaved families. Delays and errors can have damaging legal and reputational consequences for hospitals. Offices of Decedent Affairs (ODAs) have been proposed as a solution, and their potential benefits have been described in several single institution reports. The literature lacks a contemporary and comprehensive review of existing ODAs and their approaches. Objective.— To describe the process of establishing a new ODA and to provide a snapshot of the spectrum of structure, function, and impact of existing ODAs in the United States. Design.— A survey was administered to 11 established ODAs spread across the continental United States. Programs were identified through the College of American Pathologists Autopsy Committee and a Medical Autopsy Listserv. Results.— Eleven ODAs returned the survey, representing more than 190 cumulative years of experience in decedent care in the hospital setting (median, 10 years). There was a wide range in staffing (both staff size and background) as well as scope of services offered. The median ratio of hospital deaths to full-time equivalent (FTE) staffing was 360 deaths per FTE. Respondents reported that ODAs unburden clinical providers and facilitate decedent management. Some respondents reported a quicker turnover of hospital beds and shorter intervals between pronouncement of death and autopsy. ODAs increased autopsy rates when the autopsy services were part of the ODA. Conclusions.— This survey provides practical information for hospitals considering establishing a new ODA and useful benchmarks for existing ODA programs.

Context.— Decedent Affairs Offices and Programs can serve as an avenue to assist medical centers in facilitating efficient and comprehensive decedent management, despite a paucity of literature on their roles, establishment, and efficacy. Objective.— To characterize the motivations and rationales for establishing Decedent Affairs Offices. Design.— A survey was administered to 11 established Decedent Affairs Offices/Programs, identified through the College of American Pathologists Autopsy Committee and a Medical Autopsy Listserv. The questions comprehensively cover establishment, operations, and outcomes data available by institution. Results.— Survey respondents reported the rationale for starting their programs and the benefits such offices can have. Conclusions.— Decedent Affairs Offices and Programs provide a useful option to medical centers to navigate the increasingly complex task of comprehensive decedent management. The present survey helps to delineate the similarities and differences between these programs at 11 institutions, to aid nascent programs in their establishment and growth over time.

BACKGROUND: To reduce technical variation in cancer surgery, the Commission on Cancer (CoC) recently implemented 6 operative standards as part of its national cancer center accreditation process. CoC sites are evaluated for compliance with these standards through scheduled visits conducted by trained site reviewers. We characterized site reviewers’ perspectives on the implementation of the operative standards. STUDY DESIGN: Twenty interviews were conducted with CoC site reviewers using a semistructured interview guide based on the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. Themes were identified using thematic analysis mapped to the updated Consolidated Framework for Implementation Research. RESULTS: Site reviewers viewed the operative standards as an effective starting point for improving technical quality and were optimistic the standards would lead to positive change. Compliance was associated with supportive site leadership, effective interdisciplinary communication, and the availability of adequate personnel and institutional resources. In contrast, resistance from surgeons was identified as a key barrier. CoC site reviewers interpret their role as extending beyond assessing compliance, viewing themselves as advocates, educators, and partners to the sites. CONCLUSIONS: Overall, CoC site reviewers perceive the operative standards favorably. To enhance implementation of the operative standards, efforts should focus on modifiable institutional and individual-level factors, such as leadership support and surgeon engagement. Additionally, the multifaceted role of the site reviewers presents a valuable opportunity to improve compliance by formalizing the supportive relationship between reviewers and sites.

BACKGROUND AND OBJECTIVES: Gynecological cancers represent 10% to 15% of cancers in women, but brain metastases (BM) are uncommon, with limited evidence regarding their management. This study investigates the role of stereotactic radiosurgery (SRS) for BM from primary gynecological cancers. METHODS: Institutions of the International Radiosurgery Research Foundation participated in this study. Inclusion criteria required histological diagnosis of epithelial ovarian, cervical, or endometrial cancer, SRS between 2000 and 2020, and at least 1 imaging or clinical follow-up. RESULTS: A total of 276 patients having SRS for 977 BM were included. Median age at SRS was 62 years (IQR, 55-70). Primary cancer origin was ovarian in 128 (46%), cervical in 43 (16%), and endometrial in 105 patients (38%). Median Karnofsky Performance Scale was 80%, and systemic disease was active in 124 (45%) of patients. A median of 1 metastasis was treated (IQR, 1-3) per patient. Median individual metastasis volume was 0.27 cc (IQR, 0.05-1.59 cc). The majority (91%) received single-fraction SRS, using a median margin dose of 18 Gy (IQR, 16-20 Gy). Actuarial overall survival was 77%, 65%, and 44% at 6, 12, and 24 months, respectively. Predictors of worsened survival included older age, cervical and endometrial primary, previous whole-brain radiation therapy (WBRT), active systemic disease, worsened Karnofsky Performance Scale, absence of subsequent surgery, and increasing number of BM. Actuarial local control was 94% at 6 months, 89% at 12 months, and 78% at 24 months. Previous SRS or WBRT, tumor bed treatment, and cervical histology increased the risk of local failure. New remote BM and leptomeningeal dissemination occurred in 44% and 11% of patients, respectively. Adverse radiation effects (ARE) occurred in 13% of cases but were symptomatic in only 3%. Previous WBRT or SRS and increased tumor diameter increased the risk of ARE. CONCLUSION: SRS is an effective management for BM from gynecological cancers with low risks of symptomatic ARE.

Background: Trochlear dysplasia is important in recurrent patellofemoral instability (PFI); reliable metrics are essential to understand this condition and help define optimal treatment. One such measurement is the entry point to transition point (EP-TP) angle, which describes 2 components of patellar tracking from full knee extension to flexion: (1) mediodistal movement and (2) pure distal movement. Currently, measurement of this metric relies on 3-dimensional (3D) models. Purpose: To further develop the EP-TP angle metric to allow its digital measurement, to establish cohort and interrater reliability values, and to evaluate its appropriateness for clinical use. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: A data set composed of 30 recurrent PFI patient knees and 30 control knees was acquired. Each knee came with anterior views of the distal femur and curvature maps, which highlighted relevant structures such as the trochlear groove and the medial and proximal ridge. Three raters measured EP-TP angles utilizing a digital tool with and without the curvature maps. Significance of differences in means, presence of a TP, and interrater reliability with intraclass correlation coefficients were tested and evaluated according to an established guideline (<0.5, poor reliability; >0.5-0.75, moderate; >0.75-0.9, good; >0.9 excellent reliability). A significance level of .05 corrected with the Bonferroni method was assumed. Results: PFI knees had a significantly higher EP-TP angle than the control cohort (48.9° ± 10.8° vs 11.8° ± 14.6°; P < .001). Patients had a greater TP prevalence than controls (96.7% vs 10.0%). Interrater reliability for the EP-TP angle with curvature maps was significantly better than without (0.84 [95% CI, 0.76-0.89] vs 0.67 [95% CI, 0.55-0.78]; P < .001). Conclusion: The EP-TP angle is significantly different between PFI patients and controls. This study presents a digital approach for measuring the EP-TP angle, in contrast with the initially described method, which required 3D prints. This digital approach, when aided with curvature mapping, yields better reliability.

Abstract Background: Refugee, immigrant, and asylee populations face significant barriers to healthcare access, including linguistic, cultural, socioeconomic, and institutional challenges. The Refugee Education and Clinic Team (REACT) is a student-run free clinic in Maricopa County, Arizona, providing subacute care and referrals to federally qualified health centers (FQHCs). This study evaluates patient demographics, clinical needs, social determinants of health (SDH), and follow-up outcomes to identify barriers to long-term care integration. Methods: A retrospective chart review of all REACT patients (2022–2024) was conducted using electronic health records. Data on demographics, SDH, chief complaints, prescriptions, referrals, and follow-up outcomes were analyzed using descriptive statistics and logistic regression. Results: The cohort (n=95) was predominantly uninsured (63%) and faced significant social barriers, including food insecurity (30.5%), employment challenges (30.5%), and language barriers (28.4%). Musculoskeletal pain and general health check-ups were the most common concerns. Older patients had higher-than-expected rates of possible hypertension. Nearly 90% received primary care provider (PCP) referrals, yet follow-up rates remained low, with only 42% attending or planning to still attend the referred visit after their initial clinic visit with us. Successful phone outreach was a significant predictor (OR: 0.5, 95% CI: 0.31-0.77) of PCP visit attendance by multivariate logistic regression. Conclusion: REACT serves a unique population with distinct barriers to care. While the clinic facilitates healthcare entry, limited follow-up adherence highlights the need for enhanced outreach, geographically optimized referrals, and integrated allied health services to improve care continuity.

AimsCompared to lymphovascular invasion (LVI), hilar soft tissue invasion (HSTI) is a relatively novel pT2 staging parameter in testicular germ cell tumours (GCT), associated with metastasis at the time of diagnosis and a risk factor for disease relapse. Given diagnostic variability in how pathologists interpret HSTI, herein we explore interobserver reproducibility among genitourinary (GU) pathologists.MethodsTwenty haematoxylin and eosin‐stained digitized slides from testicular GCTs were distributed to 30 GU pathologists to classify each as HSTI or not HSTI based on their respective clinical practices; slides with concomitant LVI were excluded. Slides were then evaluated for the following morphologic features: tumour invasion beyond prominent hilar vessels, tumour invasion beyond the rete, tumour invasion beyond the level parallel to hilar adipose tissue and tumour within (directly touching) hilar adipose tissue. Interobserver reproducibility was assessed, and the morphological features were correlated with HSTI. Relationships between pathologists' interpretations, morphological features and HSTI were evaluated using hierarchical clustering.ResultsAlthough the diagnosis of HSTI was relatively uniform with a majority agreement (>67%) reached in 17/20 slides, overall interobserver reproducibility was only moderate (kappa = 0.50). Morphological features such as invasion beyond the level parallel to hilar adipose tissue and invasion into fat were more sensitive and specific for HSTI, while features such as invasion beyond hilar vessels and invasion beyond rete were less useful.ConclusionsThese findings suggest that more specific defined diagnostic criteria for testicular GCT HSTI are needed.
