ABSTRACT Introduction Sinonasal sarcomas are exceedingly rare entities, constituting less than 7% of head and neck sarcomas. Their complex histology needs specialized treatment, which is often based on multimodal approaches including surgery, radiation therapy, and/or chemotherapy. This manuscript aims to gather expert opinions to establish common management principles for sinonasal sarcomas. Methods This international consensus followed a modified Delphi method in seven steps, including statements definition by the core group, expert panel recruitment, and a two‐round survey. Sixty‐two statements on sinonasal sarcoma management were developed. Experts from multiple continents participated, and results were anonymized and analyzed between March and May 2025. Results A total of 44 invited experts were recruited, 43.2% otorhinolaryngologists/head and neck surgeons, 31.8% medical oncologists, and 25% radiation oncologists. Participants varied in age and experience, representing Europe (70.5%), North America (18.2%), South America (6.8%), and Asia (4.5%). Among all histologies, biphenotypic sarcoma, chondrosarcoma, leiomyosarcoma, and myofibrosarcoma are principally treated with an upfront surgical management, differently from Ewing sarcoma and rhabdomyosarcoma in which chemotherapy, eventually associated with radiotherapy, is often chosen. In the remaining histologies (angiosarcoma, liposarcoma, malignant peripheral nerve sheath tumor [MPNST], osteosarcoma, and synovial sarcoma), a precise multimodal treatment is less standardized and needs to be discussed on a case‐by‐case basis. Conclusion Sinonasal sarcomas require a histology‐driven approach to determine upfront treatment, whether surgical, medical, or multimodal. Despite this structured strategy, prognosis remains highly variable across subtypes. Multidisciplinary evaluation and individualized management in referral centers are crucial to address the biological diversity and anatomical complexity of these rare malignancies.

Background A classification system describing clinical presentation before aortic valve replacement (AVR) has recently been proposed (stable valve syndrome [SVS]), mildly symptomatic (progressive valve syndrome), or with acute and severe signs and symptoms (acute valve syndrome [AVS]). We aimed to evaluate the clinical impact, health care costs, and resource use associated with the mode of clinical presentation at the time of AVR among patients presenting with aortic stenosis. Methods Using the Market Clarity database (2017–2023), patients >18 years old with aortic stenosis and undergoing AVR (transcatheter or surgical) were included. Patients were categorized as SVS, progressive valve syndrome, or AVS based on their clinical presentation during the 1 year before AVR. All‐cause death, heart failure hospitalization, total health care costs (index hospitalization plus 1‐year follow‐up), and resource use were compared across clinical presentation groups using adjusted regression models. Results Of the 24 075 patients undergoing AVR for aortic stenosis, 270 (1.1%) had SVS, 10 195 (42.3%) progressive valve syndrome, and 13 610 (56.5%) AVS. Compared with SVS, AVS presentation was associated with increased risk of 1‐year death (adjusted hazard ratio [aHR], 2.93 [95% CI, 1.1–7.8]; P =0.03) and heart failure hospitalization (aHR, 4.15 [95% CI, 1.6–11.1]; P <0.01) after AVR. The total costs of AVR and 1‐year follow‐up were significantly higher in both the progressive valve syndrome (difference $27 410 [$13 507–$41 314]) and AVS groups (difference $36 267 [$22 302–$50 232]) compared with patients with SVS. Conclusions AVS was frequent among patients undergoing AVR and was associated with increase in death, heart failure hospitalization, health care costs, and resource use 1 year after AVR, and SVS presentation was associated with the best clinical and economic outcomes.

ABSTRACT Background Obeticholic acid (OCA) was conditionally approved in 2016 as a second‐line therapy for patients with primary biliary cholangitis (PBC) and incomplete response to ursodeoxycholic acid (UDCA) monotherapy. We aimed to evaluate the impact of OCA add‐on therapy on biochemical outcomes and safety in those patients. Methods We systematically searched MEDLINE, Embase, and Cochrane CENTRAL for papers published up to October 29, 2024, evaluating OCA in patients with PBC at the 12‐month timepoint. Pooled analyses of liver enzymes were performed using the standard mean difference (SMD) and 95% confidence interval (CI) from the OCA baseline. Side effects and the achievement of criteria for adequate response are presented in percentages (95% CI). Results We included 1285 patients from 10 studies, two of which were RCTs. The addition of OCA significantly reduced alkaline phosphatase (ALP) (SMD −0.86; −1.15 to −0.56; p < 0.001) and total bilirubin (SMD −0.29; −0.43 to −0.15; p < 0.001). Overall, 37.23% of the patients (95% CI 31.47–43.39) responded to OCA (POISE criteria). The response rate was greater in the POISE trial results compared with real‐world data (46.15% vs. 30.54%, respectively; p = 0.0089). Pruritus was the most common adverse event (40.23%; 24.65–58.07). Approximately one‐fifth of the patients stopped OCA (18.05%; 12.72–24.99), with pruritus being the main reason for discontinuation (47.70%; 34.15–61.60). Conclusion Adding OCA improves ALP, bilirubin, and biochemical remission rates in patients with PBC who did not respond well to UDCA monotherapy. Real‐world data show an attenuated response. Pruritus is the most common side effect and the leading cause of drug discontinuation.

Introduction: Sepsis-induced cardiac dysfunction (SICD) is a transient cardiac disfunction, with variable described prevalence and uncertain prognostic. This study aimed to characterize the laboratory and microbiological findings in critically ill patients with sepsis who developed left ventricular (LV) or biventricular systolic dysfunction. Methods: Patients who required intensive care unit hospitalization for sepsis were screened retrospectively. Only patients with positive cultures and echocardiography performed within 24 h from admission were included. The exclusion criteria were infective endocarditis, acute coronary syndrome, history of cardiomyopathy, severe valve disease, end-stage organ or oncological disease. Cardiac function was appreciated on transthoracic echocardiography, using LV ejection fraction for the left ventricle and tricuspid annular plane systolic excursion (TAPSE) for the right ventricle. SICD was confirmed if the systolic dysfunction found upon admission was reversible within 7–10 days. Results: A total of 100 patients with positive cultures were included. The median age was 73 and 55% were male. SICD was diagnosed in 14% of patients. Patients with SICD were more likely to develop septic shock and had longer hospital and intensive care unit stay. In-hospital mortality was 44% with no significant difference between SICD and non-SICD patients. Laboratory markers upon hospital admission showed that SICD patients had significantly higher values of lactate and transaminases. Cardiac (troponin and NT-proBNP) and inflammation markers (leukocytes, neutrophils, NLR, C-reactive protein, procalcitonin) had higher values in patients with SICD but the difference did not reach statistical significance. Streptococcal infections and polymicrobial cultures were risk factors for developing SICD. Higher rates of infections with Enterobacterales were seen in the SICD group but the difference was not significant. Conclusions: SICD patients had higher lactate, inflammation, and cardiac biomarkers levels upon admission and significantly higher rates of streptococcal infections and polymicrobial cultures.

Background/Objectives: Idiopathic intracranial hypertension (IIH) often features dural venous sinus stenosis; venous sinus stenting (VSS) improves venous outflow and intracranial pressure, but most stents are off-label, and few are engineered for intracranial venous anatomy. The aim was to synthesize animal models relevant to IIH/VSS, catalogue stents used clinically for VSS and summarize corresponding animal data, appraise current preclinical VSS research, and propose a pragmatic preclinical evaluation framework. Methods: We performed a targeted search (PubMed, Web of Science, Scopus; through to May 2025), dual-screened the records in Nested Knowledge, and extracted the model/device characteristics and outcomes as per the predefined criteria. Results: We identified 65 clinical VSS studies; most were retrospective and used off-label carotid/peripheral/biliary stents (Precise, Zilver, and Wallstent were the most frequent). Recent dedicated systems (River, BosStent) have limited animal evidence; VIVA has GLP porcine venous peripheral data demonstrating its patency, structural integrity, and benign healing outcomes. Rodent models reproduce obesity/androgen drivers with modest, sustained ICP elevation; large animal models show the technical feasibility of in sinus implantation, but no chronic focal venous stenosis model fully mirrors the IIH condition. Conclusions: Despite broad clinical uptake, the translational underpinnings of VSS in IIH remain incomplete: most devices lack intracranial venous-specific preclinical validation, and there is no existing animal model that recapitulates both IIH biology and focal sinus stenosis.

Abstract We developed and cross‑validated an integrated circulating tumor DNA assay incorporating SNVs, indels, CNAs, and SVs to distinguish neurofibromatosis type 1 patients with malignant peripheral nerve sheath tumors from those with benign plexiform neurofibromas or tumor‑free controls. Among 82 participants, the assay achieved an AUC of 0.904, compared with 0.735 for genome‑wide CNAs. We also detected recurrent disease‑specific driver alterations, relapse up to three months before diagnosis, and early clearance consistent with durable remission.

ABSTRACTSurgical biopsy of brainstem tumors carries a risk of neurological injury. We performed magnetic resonance spectroscopy (MRS) of 2‐hydroxyglutarate (2HG) and glycine in patients with brainstem tumors to assess the feasibility of detecting and quantifying 2HG in the brainstem to obviate the need for a diagnostic biopsy and to establish the clinical significance of glycine MRS in brainstem tumors in vivo. Twenty adult patients with radiographically identified presumed brainstem gliomas were prospectively enrolled in the study. Proton MRS was obtained at 3T with a protocol tailored for detection of 2HG and glycine (TE 97‐ms PRESS). Spectra were fit using LCModel software and in‐house basis signals of metabolites and lipids. The metabolite concentrations were quantified with reference to water and examined with respect to clinical outcomes, including postgadolinium MRI and overall survival time. MRS data from 19 patients were included in subsequent analysis, excluding suboptimal data from one patient. Tumors with elevated 2HG (> 1.9 mM, N = 8) and undetectable 2HG (< 0.3 mM, N = 11) were clearly distinguishable. Tumors with elevated glycine (> 1.5 mM, N = 4) showed rapid progression. Kaplan–Meier survival analyses with metabolite measures demonstrated that tumors with 2HG higher than 1.0 mM were significantly associated with a favorable prognosis (p = 0.01). In contrast, tumors with glycine higher than 2.5 mM showed a strong association with poor survival (p = 0.0005). The data confirm detection of 2HG in brainstem tumors at a concentration that is consistent with an IDH mutation and expected good prognosis, whereas elevated glycine in brainstem tumors portends rapid tumor progression and a worse prognosis.

Objectives Evaluate the value of ultrasound specialist assessment of ovarian masses over 50 mm with sonograms interpreted as possible hemorrhagic ovarian cysts (HOC). Methods Retrospective review of consecutive endovaginal pelvic US reports of premenopausal women at one organization identified adnexal masses over 50 mm maximum diameter designated as possibly being HOC (large HOC). Four ultrasound specialists reviewed studies, scoring two assessments as true or false: 1) US features are most consistent with either an ovarian hemorrhagic cyst (HOC) or endometrioma; 2) If assessment 1 was true, the mass meets O‐RADS criteria of classic HOC except for size. Results A total of 457 of 51,305 women (0.9%) had reports indicating possible large HOC. For 366 patients with established outcomes, 225 (61.5%) had a large HOC (87.1% ≤ 70 mm). Assessment 1 was true for 318 patients; outcomes showed 224 (70.4%) HOC, 89 (28.0%) endometriomas, 4 (1.3%) TOAs, and 1 (0.3%) cystadenoma. Assessment 1 was false for 48 patients; outcomes showed 1 (2.1%) HOC, 1 (2.1%) endometrioma, 6 (12.5%) other non‐neoplastic cysts, 33 (68.8%) benign neoplasms, 5 (10.4%) borderline tumors, and 2 (4.2%) high‐grade malignancies. The decrease in neoplasms and malignancies with true assessment 1 was significant ( p < .001). Assessment 2 was true for 190 patients (180 [94.7%] HOC, 9 [4.7%] endometrioma, 1 [0.5%] cystadenoma), false for 128 patients (44 [34.4%] HOC, 80 [62.5%] endometrioma, and 4 [3.1%] TOA) ( p < .001), and not applicable for 48 patients. Conclusions Ultrasound specialist review of adnexal masses designated as a possible large HOC adds value since over 10% are neoplasms (nearly 2% malignant). Ultrasound specialist assessment can expedite additional imaging or intervention when necessary and obviate follow‐up when HOC features are typical.

Abstract Minimally invasive image-guided tumor ablation techniques have been established as safe, effective methods to treat a variety of unresectable soft tissue tumors. Standard thermal ablation methods include radiofrequency ablation, microwave ablation, and cryoablation. However, newer non-thermal and/or non-invasive ablation techniques are now available as alternative options to treat soft tissue tumors, particularly those that are near critical structures or otherwise susceptible to thermal energy sink effects. The 4 types of emerging ablation techniques discussed in this review are as follows: irreversible electroporation, pulsed electric field, high-intensity focused ultrasound, and histotripsy. While the clinical trials evaluating the safety and efficacy of these ablation techniques are in their early stages, initial results are promising in the treatment of various cancers at different stages. These include potential synergistic effects when combined with chemotherapy and immunotherapy.
