BACKGROUND: The Harmony transcatheter pulmonary valve (TPV) is designed to treat severe pulmonary regurgitation in the native or surgically repaired right ventricular (RV) outflow tract. Early outcomes after TPV replacement with the Harmony valve have been positive, but longer-term data are limited. METHODS: The study included patients who received a commercially available TPV22 or TPV25 device as part of the nonrandomized, prospective Native Outflow Tract Early Feasibility Study, Harmony Pivotal Trial, and Continued Access Study. Patients completed at least 3 years of follow-up, and outcomes to 5 years were reported when available. RESULTS: Eighty-nine patients were catheterized, and 86 were successfully implanted with a Harmony TPV. Median duration of follow-up was 5 (range 0–6) years in the TPV22 group and 3 (1–4) years in the TPV25 group. At 3 years, all patients with a TPV22 and 96% of those with a TPV25 had ≤mild pulmonary regurgitation. By magnetic resonance imaging, significant improvements from preimplant to 2 years were observed in RV end-diastolic volume index, RV to left ventricular end-diastolic volume ratio, and effective RV stroke volume (all P <0.001). SF-36 quality-of-life scores improved after Harmony implantation and were sustained over 3 years. Early cases of ventricular tachycardia resolved, and there were no new arrhythmias. Adverse events up to 5 years included 3 deaths unrelated to the device or procedure, 2 cases of endocarditis that were treated (1 medically, 1 transcatheter debulking of a vegetation) and resolved, 6 patients with RV outflow tract obstruction or thrombosis resulting in valve-in valve procedures, and 1 major stent fracture resulting in surgical explant. CONCLUSIONS: At 3 to 5 years, Harmony TPV replacement resulted in sustained valve competence, beneficial cardiac remodeling, and improved quality of life. Continued monitoring is needed to assess long-term outcomes and valve performance. REGISTRATION: URL: https://www.clinicaltrials.gov ; Unique identifier: NCT01762124; NCT02979587.

Abstract Epcoritamab and glofitamab are CD20-directed bispecific antibodies (BsAbs) approved in the United States for relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL). Limited data exist for patients treated outside of trials. Patients with R/R DLBCL receiving commercial epcoritamab or glofitamab between 1 January 2023 and 15 October 2024 were collected from 21 United States institutions. Among 245 patients, 156 received epcoritamab and 89 received glofitamab, 113 were refractory to front-line therapy, 40 had MYC and BCL2 and/or BCL6 rearrangements, 147 received prior chimeric antigen receptor T-cell therapy, and 174 patients would have been ineligible for registrational trials. The overall response rate (ORR) for epcoritamab and glofitamab was 51% (23% complete response, [CR]) and 53% (30% CR), respectively. Median progression-free survival (PFS) was 2.6 months (95% confidence interval [CI], 2.0-3.8 months), and median overall survival (OS) was 7.8 months (95% CI, 6.2-11.0 months). The 6-month PFS was 36% (95% CI, 30-44) and the 6-month OS was 60% (95% CI, 54-67). Both trial ineligibility and undetectable CD20 pre-BsAbs portended shorter PFS and OS. Of 17 individuals with paired biopsies, 15 (88.2%) lost CD20 expression after BsAbs with a median time to progression of 3.7 months. This analysis including patients with R/R DLBCL shows the ORR to CD3/CD20 BsAbs was comparable to pivotal trials, although PFS and OS were lower. Baseline undetectable levels of CD20 were associated with poor outcomes. These results demonstrate the activity of BsAbs in R/R DLBCL, and underscore the importance of target antigen expression.

Abstract INTRODUCTION Monoclonal anti‐amyloid therapies are now accessible, but how these treatments influence changes within the brain is still not clear. We investigated overall and regional change in amyloid removal, glucose metabolism, and atrophy in trial participants with dominantly inherited Alzheimer's disease (DIAD). METHODS In the DIAN‐TU‐001 trial, 92 carriers received gantenerumab or placebo and underwent serial neuroimaging assessments including [ 11 C]‐Pittsburgh compound‐B (PiB) positron emission tomography (PET), [ 18 F]‐fluoro‐2‐deoxyglucose (FDG) PET, and magnetic resonance imaging (MRI). RESULTS Gantenerumab significantly reduced PiB‐PET uptake overall and in most regions and showed no changes in FDG‐PET or MRI measures. Drug effects were associated with baseline PiB‐PET uptake, and the largest effects occurred in medial regions. DISCUSSION Treated DIAD participants, and especially those with higher amyloid burden, showed a decrease in PiB‐PET uptake, which was more pronounced in the basal ganglia and medial frontal structures. These results may inform patient response and future drug trial design. Highlights Gantenerumab unevenly decreased Aβ burden as measured by PiB‐PET across brain regions. The strongest decrease in PiB‐PET uptake was in basal ganglia and medial frontal structures. Variable drug effect on Aβ was partly due to the amount of burden present before treatment. There was no regional effect on FDG‐PET metabolism or MRI volumetrics after 4 years.

Abstract Despite the growing interest in network-guided neuromodulation for epilepsy, uncertainty about the safety and long-term efficacy of thalamocortical stimulation persists. Our evaluation focused on the use of a four-lead open-loop implantable pulse generator for thalamocortical network neuromodulation. We retrospectively reviewed seven patients with diverse seizure networks—poorly localized, regional, or multifocal—undergoing thalamocortical neuromodulation. Employing a four-lead system, electrodes targeted both thalamic and cortical seizure network nodes. We assessed seizure severity, life satisfaction and sleep quality on a 10-point scale, and seizure frequency was assessed via telephone interviews and chart review. Outcomes were assessed by the Wilcoxon sign-rank test at the 0.05 significance level. Seven patients with a median age at implant of 22 years (range 14–42 years) had a median disabling seizure reduction of 93% (range 50–100%, P = 0.0156), with 100% responder rate (≥50% reduction in seizure frequency) after a median of 17 months post-implantation (range 13–60). The median improvement in seizure severity was 3.5 out of 10 points (P = 0.0312), life satisfaction 4.5 points (P = 0.0312) and quality of sleep 3 points (P = 0.062). No perioperative complications occurred. Transient seizure exacerbations (n = 2) and stimulation-related sensory/motor side-effects (n = 2) quickly resolved with parameter adjustments. One patient required surgical revision due to delayed infection. Six patients had permanent electrode placement refined by intracranial EEG trial stimulation; five patients had &gt;90% reduction in seizure frequency during trial stimulation. Thalamocortical network neuromodulation using a four-lead open-loop system is safe and associated with significant improvements in seizure control and patient quality of life. Trial stimulation during intracranial EEG shows promise for enhancing seizure network engagement and parameter optimization but requires further study. Prospective controlled trials are needed to further characterize and validate the efficacy and side-effect profile of thalamocortical network neuromodulation for epilepsy.

Background and importance Rapid sequence intubation in emergency settings may involve opioid pretreatment to blunt hemodynamic responses during laryngoscopy and intubation; however, opioids may lead to postintubation hypotension, increasing morbidity and mortality. Global clinical practice varies significantly, reflecting uncertainty about opioids’ benefits and risks. Objective Our goal was to evaluate the association between opioid pretreatment and hemodynamic instability, focusing on postintubation hypotension in adult patients undergoing emergency intubation. Design, settings, and participants We performed a systematic review of randomized controlled trials and observational studies comparing opioid administration vs. no opioids before adult emergency intubations. Searches included Cochrane, Embase, Medline, Scopus, and Web of Science databases until November 2024. Elective intubations were excluded. Eight (6708 patients) studies met criteria. Outcomes measure and analysis The primary outcome was postintubation hypotension, variably defined across studies. Secondary outcomes included hypoxemia, first-attempt success, cardiac arrest, and vasopressor use. Independent reviewers conducted data extraction, risk-of-bias assessments, and certainty evaluation. Results were qualitatively synthesized. Main results Among 6708 (2757 opioids and 3951 controls) patients, postintubation hypotension incidence varied widely (risk differences: −12.5% favoring opioids to +13.2% favoring controls). The single low-risk randomized study reported opioids increased hypotension (risk difference: 13%, odds ratio: 2.15, 95% confidence interval: 1.22–3.78). Observational studies yielded inconsistent results. Secondary outcomes showed no consistent differences. Evidence certainty was very low because of risk of bias, inconsistency, and imprecision. Conclusions Current evidence regarding opioid pretreatment effect on postintubation hypotension risk during emergency intubation is limited and conflicting.

Background and Aims: Prognosticating outcomes such as hospitalizations in outpatients with cirrhosis is challenging, especially with changing etiologies and demographics. This study aims to determine the impact of multi-omic strategies on outcome prediction. Approach and Results: NACSELD3 enrolls outpatients with cirrhosis with controlled/eradicated etiologies from 10 centers and follows them systematically. At baseline, clinical/demographic and cirrhosis details were recorded and saliva and serum samples were collected for microbiome and metabolome analysis, respectively. Multi-omic bioinformatic studies to determine the interaction of microbiota and metabolites with the clinical prediction of 6-month hospitalizations were performed. Five hundred sixty-five patients (60.2 y, 68% men, 35% alcohol, 33% metabolic dysfunction-associated steatohepatitis, 21%, eradicated HCV with MELD 3.0 12) were enrolled. One hundred sixty-three (29%) required 6-month hospitalizations; most (75%) were liver-related. Those hospitalized had worse cirrhosis severity and comorbidity indices but similar demographics and oral health variables. Salivary microbiome alpha-diversity was lower (1.96±0.48 vs. 2.09±0.45, p =0.018) with greater pathobionts ( Streptococcus , Treponema, Enterococcaceae) and lower commensal genhospitalized/noera ( Veillonella, Prevotella, Haemophilus , Lachnospiraceae spp) at baseline. Serum metabolomics showed significant separation at baseline between hospitalized/non-hospitalized patients using supervised analyses with microbial-origin (phenyllactate, secondary bile acids, indoles), choline moieties, and polyamine/GABA (3-ureidopropionate/spermidine) metabolites being most prominent. Area under the curve using random forest for clinical, microbial, and metabolomic variables was higher than that of these individually. Latent factor analysis showed clinical variables (MELD 3.0, hemoglobin, and albumin) with the greatest impact, followed by salivary microbiota and then serum microbiome for hospitalization prediction. Conclusions: In a multicenter North American outpatient cirrhosis cohort with controlled etiologies, serum metabolomics and salivary microbiome add to clinical variables to prognosticate 6-month hospitalization.
