Objectives: Smoking is a key risk factor for pancreatitis, contributing to pathogenesis and disease progression. Data regarding second-hand smoking, or passive smoking (PS) exposure, are lacking. We therefore aimed to assess the impact of PS exposure across the pancreatitis spectrum. Methods: We analyzed baseline data from the PROCEED study, a multicenter study in the United States including patients with acute (AP), recurrent acute (RAP), and chronic (CP) pancreatitis. Participants detailed their individual smoking history and PS exposure, which was compared between AP, RAP, and CP subgroups. Participant factors and clinical characteristics were compared by level of individual and PS exposure. Results: Among 1369 participants (190 AP, 498 RAP, 681 CP), 346 (25.3%) were current and 409 (29.9%) were former smokers. The CP subgroup had the highest proportion of current smokers (36.7% CP vs 15.1% RAP, 11.1% AP, P < 0.001). PS exposure was also significantly higher in the CP subgroup (68.6% CP vs 58.2% RAP, 55.3% AP, P < 0.001). A minority (16.3%) with CP reported no smoking exposure (by self or passive) while nearly half smoked ≥20 pack-years. The mean PS duration was significantly higher in CP participants (21.8 y) compared with those with AP (17.8 y) or RAP (18.9 y) ( P < 0.0166). Conclusions: In this multicenter study, we affirmed an association with smoking use and intensity with CP-related complications. For the first time, we report a high prevalence of prior exposure to passive smoking in all pancreatitis subtypes, which requires further study to understand the impact on disease outcomes.

Abstract Viral infections are estimated to contribute to 12% to 20% of all cancers worldwide, with virus-driven malignancies disproportionately affecting low- and middle-income countries, whereas metabolic and nonviral factors predominate in high-income regions. Key oncogenic viruses that cause solid tumors include high-risk human papillomaviruses, Epstein–Barr virus, hepatitis B virus, hepatitis C virus, Kaposi sarcoma–associated herpesvirus, and Merkel cell polyomavirus. Immune checkpoint inhibitors (ICI) have revolutionized cancer therapy by boosting immune responses against tumors. Although viral infection–associated tumors often exhibit “hot” immune profiles, clinical outcomes with ICIs remain inconsistent. Some studies report improved survival in virus-associated cancers, whereas others indicate no clear benefit, which might reflect high variability in tumor microenvironments and immune responses. In this review, we aim to explore the direct and indirect contribution of different viruses to carcinogenesis in solid tumors, with a particular focus on immunotherapy effectiveness based on infection status.

OBJECTIVES: Current research does not address the existence and impact of structured tele-critical care (TCC) training on the delivery of care in the ICU. This pilot study aimed to evaluate the association between on boarding elements focused on training and clinicians perceptions of delivery of care. DESIGN: Cross-sectional survey study. SETTING AND PARTICIPANTS: Critical Care professionals at four U.S. hospitals, professional meetings and Society of Critical Care Medicine’s International Membership base. Participants were active clinicians who practice in the TCC setting. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 432 participants responded to the survey, 227 met the eligibility criteria (52.5%) and were included in the analysis. Respondents were a multi-professional group of TCC clinicians aged between 35–55 years of age (56.4%). Seventy-four percent of respondents reported having orientation before providing TCC, 46% reported having formal mentorship, and 66% reported formal training on their institutional platform. Provision of orientation before participating in a TCC program was associated with higher ratings of feeling prepared (odds ratio [OR], 3.52; p < 0.001) and feeling accepted as part of the ICU team (OR, 2.21; p = 0.008). Mentorship was associated with feeling more prepared (OR, 8.2; p < 0.001) and higher comfort in delivering care (OR, 2.78; p = 0.016). Platform training was associated with feeling more prepared (OR, 4.66; p < 0.001), comfortable in delivering care (OR, 3.6; p = 0.002), feeling accepted as part of the team (OR, 3.18; p < 0.001), and more likely to participate in quality improvement (OR, 2.51; p = 0.001). A site visit also made a positive impact in feeling prepared (OR, 2.86; p < 0.001), comfortable (OR, 4.95; p = 0.002), feeling like recommendations were accepted (OR, 3.73; p < 0.001), more likely to recommend TCC (OR, 3.18; p = 0.001), and participating in quality improvement (OR, 3.24; p < 0.001). CONCLUSIONS: In this pilot study, structured training utilizing orientation, mentorship, and platform training as surrogates, along with a site visit before beginning delivery of care in a TCC setting, were associated with more positive perceptions in the delivery of care domains assessed. We highlight potentially important factors that warrant further evaluation and assessment of the need for standardization across TCC programs.

PURPOSE STELLAR (ClinicalTrials.gov identifier: NCT02796261 ) was a phase III, randomized, open-label trial of eflornithine + lomustine versus lomustine monotherapy in patients with recurrent grade 3 astrocytoma. METHODS At trial initiation, eligibility criteria included: age ≥18 years, anaplastic astrocytoma (2016 WHO CNS Tumor classification [WHO CNS4]), first recurrence ≥6 months after radiation and temozolomide (TMZ), Karnofsky performance status ≥70, and no imaging findings consistent with grade 4 glioblastoma. Random assignment (1:1) was stratified by isocitrate dehydrogenase ( IDH ) mutation, age, resection extent, and geography. Patients received eflornithine (2.8 g/m 2 orally, every 8 hours [2 weeks on, 1 week off]) + lomustine (90 mg/m 2 orally, once every 6 weeks), or lomustine monotherapy (110 mg/m 2 once every 6 weeks). The primary end point was overall survival (OS). RESULTS Among 343 patients randomly assigned across 74 sites in eight countries, there was no difference in survival between eflornithine + lomustine and lomustine monotherapy (median OS 23.4 v 20.3 months, hazard ratio [HR], 0.94). Following changes in classification and grading in the 2021 WHO CNS5, a subset analysis of patients with IDH- mutant, grade 3 astrocytoma (n = 196), defined in 2024, before unblinding, showed clinically meaningful improvements in median OS with eflornithine + lomustine versus lomustine monotherapy (34.9 v 23.5 months, HR, 0.64) and median progression-free survival (PFS, 15.8 v 7.2 months, HR, 0.57). No differences were observed among patients with CNS grade 4 disease. Grade ≥3 treatment-emergent adverse events of relevance were related to reversible myelosuppression (eflornithine + lomustine 42% v lomustine monotherapy 29% of patients) and hearing impairment (24% v 0%). No new safety signals were identified. CONCLUSION Clinically meaningful improvements were observed; eflornithine + lomustine doubled PFS and improved OS in patients with recurrent IDH -mutant, grade 3 astrocytoma, but not grade 4 tumors, after prior radiotherapy and TMZ, consistent with its cytostatic mechanism of action.

Importance Despite treatment advances, metastatic recurrence continues to be a leading cause of morbidity and mortality. Empirical data on the incidence and survival after metastatic recurrence remain limited, as cancer registries historically do not collect data on recurrence. Objective To estimate the cumulative incidence (CMI) of metastatic recurrence among adolescents and young adults diagnosed with earlier-stage disease and compare survival to those with metastatic disease at diagnosis. Design, Setting, Participants This was a retrospective cohort study of adolescents and young adults aged 15 to 39 years who were diagnosed with nonmetastatic cancers from 2006 to 2018. Adolescents and young adults were identified from the California Cancer Registry linked with statewide hospitalization, emergency department, and ambulatory surgery encounters from the California Department of Health Care Access and Information. Data were analyzed from December 2023 to June 2025. Exposures Cancer types, including melanoma, sarcoma, and breast, cervical, colorectal, testicular, and thyroid cancers. Main Outcomes and Measures Metastatic recurrence was identified using International Classification of Diseases, Ninth Revision, Clinical Modification, and Tenth Revision, Clinical Modification, metastatic disease codes at least 6 months after cancer diagnosis or from an underlying cancer cause of death. Follow-up was through December 31, 2020. Results Of a total of 48 406 adolescents and young adults (median [IQR] age at diagnosis, 33.0 [28.0-37.0] years; 67.4% female), 9.2% had metastatic disease at diagnosis, and 9.5% had metastatic recurrence. Among 43 935 adolescents and young adults who presented with nonmetastatic disease, the 5-year CMI of metastatic recurrences was highest among patients with sarcoma (24.5%; 95% CI, 22.6%-26.6%) and colorectal cancer (21.8%; 95% CI, 20.3%-23.4%) and intermediate for cervical (16.3%; 95% CI, 15.0%-17.6%) and breast (14.7%; 95% CI, 14.0%-15.4%) cancers. The CMI for metastatic recurrence increased with increasing stage at diagnosis, with 5-year CMIs higher than 30% for all stage III cancers (except thyroid). The 5-year CMI of metastatic recurrence also increased over time for cervical cancer (2006-2009: 12.7% [95% CI, 10.8%-14.8%]; 2015-2018: 20.4% [95% CI, 17.5%-23.6%]) and decreased for colorectal cancer (2006-2009: 24.4% [95% CI, 21.3%-27.6%]; 2015-2018: 19.2% [95% CI, 16.4%-22.2%]). Survival after metastatic recurrence was worse than metastatic disease at diagnosis for all cancer types, except for testicular and thyroid cancers. Conclusions and Relevance The findings from this cohort study highlight the overall burden of metastatic disease in adolescents and young adults, expanding the knowledge of metastatic recurrences that help improve care for adolescent and young adult survivors throughout the cancer survivorship spectrum.

In 2023, the American Congress of Rehabilitation Medicine Brain Injury Interdisciplinary Special Interest Group (ACRM BI-ISIG) Mild Traumatic Brain Injury (TBI) Task Force published updated diagnostic criteria for mild TBI. These criteria were developed in collaboration with a panel of 32 subject matter experts in mild TBI using the Delphi method. The 2023 ACRM diagnostic criteria marked the first update since 1993, incorporating three decades of research advancements in our understanding of mild TBI. To facilitate the consistent use of the new diagnostic criteria, the ACRM BI-ISIG Mild TBI Task Force initiated a special project in September 2023 to develop a structured interview to apply the ACRM diagnostic criteria for mild TBI in clinical and research settings. The purpose of this article is to describe the development of the ACRM Structured TBI Interview and the accompanying documents. The ACRM Structured TBI Interview was developed in four phases: (1) initial development of a draft interview by two project leads, (2) review and revision over three rounds by 17 members of the ACRM BI-ISIG Mild TBI Task Force, (3) external review by 19 subject matter experts in mild TBI, and (4) field testing of the ACRM Structured TBI Interview by 11 interviewers who completed 25 diagnostic interviews. In addition to the ACRM Structured TBI Interview, three other documents were developed to help facilitate the administration of the interview (Administration Guide) and to apply the diagnostic criteria (Diagnostic Coding Form and Diagnostic Flow Diagram). A Short Form was also developed for use in contexts where administering the full structured interview is not feasible due to time constraints.

Context.— Treatments are available for common forms of systemic amyloidosis that show promise for extending and improving the quality of life for patients. Early diagnosis and accurate identification of amyloid fibril type are crucial for successful treatment, but the diagnosis and workup of amyloidosis is inconsistent among pathologists and laboratories. Thus, the goal of this guideline is to offer recommendations for proper testing and workup for amyloidosis to optimize patient care. Objective.— To establish evidence-based recommendations for appropriate laboratory testing to detect amyloidosis and identify the specific amyloidogenic protein. Design.— The College of American Pathologists convened a panel of experts to develop recommendations following the standards established by the National Academy of Medicine for developing trustworthy clinical practice guidelines. The panel conducted a systematic literature review addressing 6 key questions. Using the Grading of Recommendations Assessment, Development and Evaluation framework, recommendations were created based on the available evidence, certainty of that evidence, and key judgments as defined in the framework. Results.— Four conditional recommendations and 3 good practice statements were established to provide guidance for proper testing and workup of amyloidosis. Conclusions.— This guideline summarizes the available evidence on the diagnosis and workup of systemic amyloidosis in tissue samples, including the challenges and limitations of common approaches and techniques. Recommendations for pathologists and laboratories receiving these samples are provided.

ABSTRACT Objectives To review septal perforation management and outcomes in patients with hereditary hemorrhagic telangiectasia (HHT). Methods Collection and presentation of patient demographic, perforation size, and prior perforation and HHT treatment data over a 20‐year period. Symptom and quality of life treatment outcomes were determined using the Nasal Obstruction Symptom Evaluation (NOSE)‐Perf scale and the 5‐Factor Glasgow Inventory (GBI‐5F), respectively, in patients treated since 2017. Results Nine patients met study criteria. Mean (range) age was 64.4 (52–80) years and seven were biological males. Mean (range) perforation length and height were 1.9 (1.2–2.6) and 1.4 (1.0–1.8) cm. Four patients were treated with a customized septal button, one with posterior septal resection, and four with endonasal bilateral mucosal flap repair supported with an interposition graft. The button prostheses were well tolerated and the surgical closures successful at 8–60 months postoperatively. Subjective responses in the first three patients, and NOSE‐Perf with GBI‐5F scores in the latter six patients, demonstrated symptom and quality of life improvement for all patients. Perforation repair patients demonstrated substantial improvement in mean GBI‐5F subdomain scores for quality of life, self‐confidence, and social involvement and all have undergone sodium tetradecyl sclerotherapy injection postoperatively without re‐perforation. Conclusion Symptom and quality of life improvement can be achieved in HHT patients with a perforation using customized septal buttons, posterior septal resection, or bilateral flap surgical repair. Surgical closure combined with injection sclerotherapy is feasible with a low risk of re‐perforation and represents an effective treatment strategy in selected patients. Level of Evidence 4.

Abstract DDX3X dysfunction causes an X-linked multisystem disorder with high penetrance and variable expressivity. The phenotypic spectrum spans from learning disability without somatic involvement to profound intellectual disability with severe impairments in the central nervous system and other organs. A few multicenter studies and single case reports have previously highlighted some common phenotypic patterns but were unable to delineate correlations between underlying DDX3X variants and phenotypic findings.From the second largest patient cohort published to date, we analysed clinical, psychometric and diagnostic findings of 52 female and 7 male individuals, harbouring de novo and inherited DDX3X variants. These female patients revealed previously unknown quantitative correlations between variant type and localization and specific phenotypic findings (growth features, epilepsy, brain anomalies, dysmorphisms, motor-focused neurological findings). Moreover, by analysing the in silico folding and RNA binding capability of mutant DDX3X monomers, we were able to delineate novel correlations between DDX3X monomer misfolding grade and phenotypic severity.
