BACKGROUND AND OBJECTIVES: The prospective single-arm nonrandomized SCENT (Surpass Intracranial Aneurysm Embolization System Pivotal) trial on flow diverter treatment of large and giant intracranial aneurysms (IA) was analyzed for patients' age and IA characteristics affecting stroke and occlusion rates over 5 years (Trial registration NCT01716117). METHODS: Impact on major ipsilateral stroke and IA occlusion was studied by stratifying age as 65 years and younger vs older than 65. Kaplan–Meier estimates of time to both endpoints, stratified by age, were created. Univariate predictors of time-to-stroke were analyzed using univariable proportional hazards regression models. Limited bivariable modeling was also attempted. RESULTS: Of 180 patients with large or giant IA enrolled, 119 were 65 years and younger, whereas 61 were older than 65 years. The 3-year risk of stroke for the older than 65 years group (19.7%) was more than double that of the 65 years and younger group (9.2%), P = .047. No new strokes were reported between 3 and 5 years. Four patients (2.2%) experienced aneurysm rupture within the first week post-treatment, 3 being 65 years and younger and the fourth older than 65 (>.99). Complete IA occlusion within age strata at 1 year was: older than 65 60% (33/55), 65 years and younger 79.1% (87/110), P = .009, 3 years: older than 65 67.6% (25/37), 65 years and younger 82.5% (66/80), P = .071, and 5 years: older than 65 85.7% (18/21), 65 years and younger 91.8% (56/61), P = .417. CONCLUSION: Age older than 65 was associated with an increased risk of stroke and predictive of incomplete healing and increased time to healing.

Abstract Objective: Outpatient parenteral antimicrobial therapy (OPAT) programs continue to evolve with increases in multidisciplinary teams, complex oral antibiotics, long-acting injectable antimicrobials, patients with substance use disorder (SUD) and telehealth. We sought to examine how OPAT programs are currently structured and identify barriers to safe care. Design: Cross-sectional survey. Participants: Physician, pharmacist, and advanced practice providers (APP) Emerging Infections Network (EIN) members. Methods: A survey was conducted between February and March 2025 to assess OPAT structure, expansion to complex outpatient antimicrobial therapy (COpAT), and barriers to safe OPAT care. Results: Of 1639 EIN members, 622 (38%) responded; 75% reported an active role in OPAT. Oversight of patients on COpAT was reported by 59%, and mandatory ID consultation for OPAT by 59%. Eighty-one percent reported >75% of OPAT patients were followed by ID. Most patients received OPAT at home (78%) followed by post-acute care facilities. Outpatient and inpatient ID physicians were responsible for laboratory test monitoring (75% and 30% respectively), while 37% reported a multidisciplinary OPAT team and 32% reported non-specialists. Respondents cited inadequate support in data analysis, administration, information technology and financial support for clinical staff. Common challenges were lack of leadership awareness (51%), difficulty managing patients with SUD (50%) and timely access to laboratory test results (48%). Conclusions: ID physicians were commonly involved in OPAT care, with many programs expanding to COpAT. Several barriers to the safe delivery of OPAT remain, including lack of institutional support, reimbursement and poor communication between stakeholders.

Abstract Hairy cell leukemia (HCL) and HCL variant (HCLv) are distinct, rare, and chronic splenic B-cell lymphomas/leukemias that partially overlap in clinicopathologic presentation but differ in genetic basis, prognosis, and management. HCL is caused by the BRAF-V600E kinase–activating mutation in >95% of the patients, usually has excellent responses to chemotherapy with purine analogues, and is also amenable to BRAF inhibitor–based targeted treatments. In contrast, HCLv lacks BRAFV600E mutation, requires combined therapy with purine analogues in addition to rituximab, and generally shows less durable responses. Here, an international team of hematologists, experts on these rare diseases, was convened by the Hairy Cell Leukemia Foundation to update the previous guidelines (published in 2017) by providing a summary of current methods to diagnose and manage patients with HCL and HCLv as well as a prospective on newer targeted therapies to further improve outcomes.

Importance Transcatheter tricuspid valve replacement (TTVR) demonstrated superior outcomes over medical therapy in patients with severe tricuspid regurgitation (TR) in the Edwards EVOQUE Transcatheter Tricuspid Valve Replacement: Pivotal Clinical Investigation of Safety and Clinical Efficacy Using a Novel Device II (TRISCEND II) randomized clinical trial, and received regulatory approval in the US in 2024. Contemporary real-world data on its effectiveness and safety remain limited. Objective To evaluate 30-day clinical, echocardiographic, and health status outcomes of TTVR in real-world use. Design, Setting, and Population Retrospective cohort study of all consecutive patients who underwent TTVR in the US from February 2024 through March 2025 in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. Patients had symptomatic, severe TR despite optimal medical therapy and TTVR was deemed appropriate by a heart team. Statistical analysis was conducted from September 2025 to February 2026. Exposure Device-enabled TTVR. Main Outcomes and Measures Thirty-day event rates (all-cause death, stroke, bleeding, new cardiac implantable electronic device [CIED] implantation, heart failure hospitalizations), TR reduction, and changes in health status (New York Heart Association [NYHA] functional class and Kansas City Cardiomyopathy Questionnaire Overall Summary [KCCQ-OS] score) are reported. Subgroup analyses examined the impact of baseline CIED status on outcomes. Results Among 1034 attempted procedures at 82 centers (mean [SD] age, 77.1 [10.6] years; 69.1% female; 73.2% NYHA functional class III/IV), a valve was successfully implanted in 1017 patients (98.4%). Mild or less TR was achieved in 98.4% of patients post procedure and in 97.7% at 30 days. At 30 days, all-cause mortality was 3.1%; stroke, 0.2%; bleeding, 7.9%; new CIED, 15.9% in CIED-naive patients; and heart failure hospitalization, 3.1%. There were significant improvements in NYHA functional class (class I/II, 82.7%; P < .001) and mean KCCQ-OS score (22.4 points; P < .001) from baseline to 30 days. There were no significant differences in 30-day mortality ( P = .47), heart failure hospitalization ( P > .99), and functional outcomes ( P = .55) when patients were stratified by baseline CIED status. Conclusions and Relevance Early US real-world experience with TTVR confirms safety and effectiveness in patients with severe TR. Thirty-day outcomes are consistent with the TRISCEND II pivotal trial, demonstrating acceptable safety, near-complete TR elimination, and significant health status improvements in an older, comorbid population. Rates of new CIED implantation and bleeding were lower than randomized clinical trial experience.

ABSTRACT Background and Aims Primary sclerosing cholangitis (PSC) is a progressive cholestatic liver disease with a high risk of malignancy and limited therapeutic options. Both the American Association for the Study of Liver Diseases (AASLD) and the European Association for the Study of the Liver (EASL) recommend structured baseline evaluation, fibrosis staging and longitudinal surveillance. However, real‐world adherence to these practices in North America remains unclear. Methods We conducted a retrospective cohort study of 1300 patients with PSC enrolled in the Consortium for Autoimmune Liver Diseases (CALiD) registry between 2018 and 2024 across 19 centres in North America. Guideline adherence was assessed for diagnostic measures at baseline (colonoscopy to establish IBD status and noninvasive fibrosis staging) and longitudinal surveillance (colonoscopy in PSC‐IBD, abdominal imaging for hepatobiliary cancer surveillance and CA 19‐9 testing). Prescribing patterns for ursodeoxycholic acid (UDCA) were also characterised. Multivariable logistic regression was used to evaluate demographic, clinical and socioeconomic predictors of adherence. Results At diagnosis, 78.8% of eligible patients with available data underwent colonoscopy to establish IBD status, and 45% underwent noninvasive fibrosis staging. During follow‐up, only 30%–35% of patients with PSC‐IBD underwent colonoscopy annually, while abdominal imaging for hepatobiliary cancer surveillance declined from 74% at Year 1 to 51% by Year 4. CA 19‐9 testing was documented in 47% over 5‐year period. UDCA was prescribed in 51% at baseline, with median dose of 12.5 mg/kg/day. Socioeconomic factors, including lower education and household income, were associated with reduced adherence, while cirrhosis strongly predicted completion of surveillance imaging. Conclusions Adherence to guideline‐based care in PSC remains suboptimal in North America Suboptimal adherence was observed for strongly recommended practices with longstanding guideline support (colonoscopy to establish IBD status; annual CRC surveillance in PSC‐IBD) as well as practices where guideline consensus has evolved more recently or where societies differ (baseline fibrosis assessment; hepatobiliary cancer imaging). Efforts to standardise care and address socioeconomic barriers are urgently needed to improve outcomes.

ABSTRACT Oligo‐secretory and non‐secretory MM present a clinical challenge due to the difficulties in initial diagnosis, response to treatment assessment, and relapse detection. They are excluded from most clinical trials, which typically require measurable disease. We describe the characteristics and outcomes of 86 patients with secretory myeloma at diagnosis who developed an OSR, matched 1:1 to a cohort with secretory relapse (SR). With a median follow‐up of 9.3 years, 16.6% (48/289) of evaluable patients developed an OSR. Lower levels of light chains at presentation, and younger age are predictive of an OSR. The median OS since relapse of the OSR group was 4.01 (95% CI 1.625–6.395) versus 3.25 (95% CI 2.255–4.245) years in the SR control group ( p = 0.4). A third of our OSR cohort had a subsequent SR. We did not find any predictive factor for SR after OSR. The median OS of the subgroup of patients who developed a SR after OSR was 3.35 years (95% CI 1.541–5.159), versus 5.8 years (95% CI 2.072–9.528) in the group that remained oligo‐secretory ( p = 0.336). The median TTNT of the SR after OSR group was 1.68 years (95% CI 0.341–0.919) versus 4.58 (95% CI not reached‐not reached) in the group that remained oligo‐secretory ( p < 0.001).

Abstract Background Recurrent alcohol use is a major determinant of liver‐related outcomes in patients recovering from alcohol‐associated hepatitis (AH). However, the timing and predictors of return to drinking (RTD) are not well‐studied. Methods We analyzed alcohol use among patients with AH enrolled in two AlcHepNet multicenter studies: a Phase 2b randomized controlled trial and a prospective observational study. TimeLine FollowBack (TLFB) assessed drinking at each visit. RTD was defined as any alcohol use since the previous visit. The cumulative incidence of RTD was evaluated using the Fine–Gray method, with death as a competing risk. Factors associated with RTD were evaluated using univariate and multivariate Cox regression. Results Among 518 patients alive at Day 28, RTD occurred in 7.7%, 21.7%, and 30.8% at 30, 90, and 180 days, respectively. Patients with moderate AH (mAH, MELD 11–19, n = 103) had a higher RTD incidence at 180 days than those with severe AH (sAH, MELD ≥20, n = 415) (44.3% vs. 27.5%; p = 0.01). RTD was associated with higher AUDIT scores, family history of alcohol use disorder (AUD), lower education, greater alcohol use at baseline, lower MELD scores, and less ascites (all p ≤ 0.01). In multivariable analysis, >20 drinking days in the prior month was associated with increased risk of RTD (HR: 3.46, 95% CI: 2.21–5.39), whereas college education or higher was protective (HR: 0.53, 95% CI: 0.32–0.88). Conclusion RTD occurred in 22% of AH patients within 90 days postrecovery, highlighting the need for early AUD interventions. Frequent drinking days at baseline and lower education were strongly linked to early RTD.

Abstract The INFORM trial (NCT01670500) was a randomized, two-arm Phase II neoadjuvant study comparing the efficacy of a platinum-based regimen (cisplatin) versus an anthracycline (AC)-based regimen in participants with germline BRCA1/2 mutations and early-stage, HER2-negative breast cancer. MicroRNAs (miRNAs) are emerging as promising non-invasive biomarkers for disease detection and treatment monitoring. The initial aim of this study was to evaluate whether pretreatment plasma miRNA profiles were associated with treatment outcomes in the INFORM trial cohort. Pretreatment plasma samples from 97 INFORM participants (n=53 cisplatin and n=44 AC) were screened for 352 miRNAs commonly implicated in cancer using the qPCR-based ID3EALTM Cancer Panel. Twenty out of 53 participants achieved residual cancer burden (RCB) score of 0 or 1 with cisplatin and 20/44 with AC. Higher plasma miR-362-3p expression was associated with a favorable response to cisplatin (1.7-fold; p&lt;0.01), but not to AC. MiR-362-3p expression in paired pretreatment tumor biopsies (n=79) did not significantly correlate with plasma expression and was not associated with RCB 0/1 (p&gt;0.05). In TCGA, miR-362-3p expression was higher in breast tumors than in adjacent normal tissue, and higher in triple negative breast cancers (TNBCs) compared with hormone receptor-positive tumors (both FDR&lt;0.001), independent of BRCA mutation or Single Base Substitution Signature 3 (SBS3) status. The miR-362-3p findings in INFORM did not replicate in a sister trial, TBCRC 030 (NCT01982448; 11 out of 46 cisplatin-treated patients achieved RCB 0/1, p=0.46). These results suggest that while miR-362-3p is unsuitable as a circulating biomarker for cisplatin response, it may play an important biological role in mediating cisplatin sensitivity in TNBCs, independent of BRCA1/2 mutations. Functional studies demonstrated that miR-362-3p is expressed and secreted by TNBC cell lines, operates as a tumor suppressor, and generally correlates with cisplatin sensitivity. Overexpression of miR-362-3p rendered MDA-MB-231 and CAL-51 cells cisplatin sensitive, while knockdown induced resistance in MDA-MB-436 cells. Ongoing studies are testing whether these effects translate in xenograft models. In silico and functional assays identified BCLAF1, a DNA damage response (DDR) regulator, as a direct target of miR-362-3p. Overexpression of miR-362-3p suppresses BCLAF1 mRNA and protein levels. Our findings demonstrate that miR-362-3p enhances cisplatin responsiveness by targeting BCLAF1. A miR-362-3p-based therapeutic may be useful as a co-agent to enhance tumor responses to platinum-based chemotherapy. Citation Format: Zhaoji Liu, Shizhong Ke, Xiaohui Li, Catherine Wu, Madison M.

Abstract Introduction Revascularization to prevent limb loss is not feasible or represents a very high risk in a significant proportion of patients with chronic limb-threatening ischaemia (CLTI). No standard definition currently exists to define this population of patients. The aim of this study was to develop a consensus-based, multidomain definition to improve clinical assessment and reporting of studies in people with ‘no option’ (NO) or ‘poor option’ (PO) CLTI. Methods A modified Delphi process was conducted with 164 specialists from 30 countries. Two iterative survey rounds were used to reach consensus, defined as ≥70% agreement with a score of ≥7 on a nine-point scale. Results Some 164 international vascular specialists participated in the study, averaging 19 years of experience. A multidomain framework including arterial disease anatomy, biology, risk, function, and context (ABRFC) achieved 83% consensus. A ‘desert foot’ was defined as the absence of distal arterial revascularization targets on advanced non-invasive imaging, invasive digital subtraction angiography, and at least one failed endovascular revascularization attempt (81.6% agreement). Inadequate autogenous bypass conduit was defined as the lack of usable autologous vein across all four limbs (85% agreement). Patients were classified as NO for revascularization if they present with ‘desert foot’, prohibitive medical risk, a non-functional limb, or in those patients who refused arterial revascularization. PO revascularization patients combined factors such as severe infection, lack of autologous vein, or treatment non-compliance (72.1% agreement). Conclusion This consensus study established a structured, expert-validated definition of no option or poor option for revascularisation of patients with CLTI. The multidomain ABRFC framework provides a foundation for standardized clinical assessment, trial design, and future guideline development.
