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.

Background: Rib remodeling, particularly targeting ribs 11 and 12, is gaining popularity in aesthetic body contouring to reduce waist circumference. Although rib manipulation techniques have been applied in other surgical fields, their use in plastic surgery has focused on achieving aesthetic goals. This study investigates the complications associated with rib remodeling techniques to enhance waistline contouring. Methods: A global cross-sectional survey was conducted among board-certified plastic surgeons who perform rib remodeling. Data from 2351 patient records (2018–2024) were collected, including demographic details, surgical information, and complications. Rib remodeling techniques assessed included surgical greenstick fracture modification and osteosynthesis. Results: The overall complication rate was 3.7% (86 of 2351 patients). Hyperpigmentation (17.4%), nonconsolidation (15.1%), burns (12.7%), and corset-related pressure ulcers (12.7%) were the most common complications. Major complications such as pneumothorax were rare (0.17%) and occurred only in RibXcar cases. Rib extraction/removal techniques had no reported complications, whereas Riboss had the lowest complication rate (1.96%) due to the use of osteosynthesis material for fracture stabilization. Conclusions: The incidence of complications related to the rib remodeling procedures in our study was 3.7%. However, some procedure-related complications—such as pneumothorax and hemothorax—can pose serious risks to the patient’s life. Nevertheless, when performed by a well-trained surgeon with an adequate learning curve, these procedures can be considered safe.

The brain is a highly recurrent, nonlinear network hypothesized to remain near the edge of chaos for optimal performance. Excitation and inhibition must be balanced precisely within every neuron to ensure a consistent level of dynamical stability and rich dynamics during transition to chaos. However, analysis of biologically realistic synaptic weight matrices suggests that sparsity and low-dimensional structure interact such that there is no known synaptic balancing rule that constrains the stability (i.e., eigenvalues) of the network while also preserving computationally useful, low-dimensional structure. Further, even if a network were well-balanced, external stimuli interact with the nonlinear activation functions to unbalance the network in real time. Therefore, the brain must utilize dynamic, rather than static, mechanisms to actively regulate its level of stability. We propose that two specific adaptation mechanisms, spike frequency adaptation (SFA) and short-term synaptic depression (STD), continuously modulate the effective connectivity, keeping the brain near the edge of chaos and reducing dynamical fluctuations caused by stimuli. This theoretical framework links intrinsic and synaptic negative feedback mechanisms to network-level dynamics. This offers an explanation of why data-driven modeling of human brain signals, an exciting and useful method in epilepsy and anesthesiology research, seems to require linear time-varying (LTV) models which are refit every half second: difficult to observe adaptation processes interact with nonlinearities to make connectivity effectively dynamic at the macroelectrode scale. We suggest that compromised adaptation may underlie neurological conditions characterized by altered excitability, and that targeted brain stimulation could be used to probe the regulatory action of adaptation.

Abstract The Bridging the Gaps (BTG) in Leukemia, Lymphoma and Multiple Myeloma Consensus Conference 2025 brought together a multidisciplinary group of oncology experts to address the complexities of lymphoma management, focusing on mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), and diffuse large B‐cell lymphoma (DLBCL). This article presents consensus recommendations developed through a modified Delphi process, which emphasize the need for tailored therapeutic strategies in light of recent advancements in treatment options. Key recommendations include the screening for high‐risk features in MCL, use of the BOVen regimen (zanubrutinib, obinutuzumab, and venetoclax) for TP53 ‐aberrant cases, and integration of chimeric antigen receptor T‐cell therapy for patients with mantle cell lymphoma that is refractory to covalent Bruton tyrosine kinase inhibitors. For CLL, recommendations include consideration of time‐limited therapies for younger patients and a “watch and wait” strategy for asymptomatic patients despite the improved activity and safety of current treatment regimens. For DLBCL, this article highlights the challenges in treatment sequencing and the role of circulating tumor DNA and minimal residual disease testing in monitoring disease progression. Overall, the conference describes the importance of ongoing research to refine management strategies and improve patient outcomes in lymphoma care, addressing the gaps in clinical practice where high‐level evidence is lacking.

PURPOSE Approximately three quarters of patients with sarcoma report financial toxicity, defined as the psychosocial and economic burden of cancer care. The Comprehensive Score for Financial Toxicity (COST) is a screening questionnaire validated in patients with cancer. However, its use is not widespread in sarcoma care, likely in part due to its complexity. This study aimed to characterize financial toxicity in patients with sarcoma and evaluate whether shorter screening tools can identify high-risk patients. METHODS We conducted a survey and retrospective cohort study of patients treated for sarcoma at a large, academic sarcoma center in 2016-2024. Patients completed the COST questionnaire (11 graded questions, each scored on a five-point Likert scale from 0 to 4) and the shorter, four-question Worry about Affording Healthcare Scale (WAHS). We obtained clinical information from the electronic health record. We used descriptive statistics to summarize responses to COST, Pearson's correlation coefficient to assess the association between WAHS and COST, and stepwise Spearman correlations to evaluate whether an abbreviated (1-4 question) version of COST correlated highly with total COST score. RESULTS Among 205 participants, the mean COST score was 20/44 (standard deviation = 6; lower scores indicate greater financial toxicity). Respondents worried most about job loss (mean COST: 0.99) and family finances (mean COST: 1.11). WAHS was weakly correlated with COST (r = 0.47, P < .01). A four-item abbreviated COST tool was strongly correlated with the total COST (ρ = 0.906, P < .0001) and demonstrated high sensitivity (96%) and moderate specificity (75%). CONCLUSION An abbreviated four-item COST tool could act as a clinically feasible, accurate screening tool after external validation. Routine financial toxicity screening could facilitate timely detection and referral to essential financial navigation resources.

Introduction Preoperative testosterone exposure has been associated with various health outcomes, but its impact on postoperative complications in patients undergoing total shoulder arthroplasty (TSA) has not been fully explored. This study aims to evaluate the association between preoperative testosterone exposure and postoperative medical and surgical complications in patients undergoing TSA. Methods A retrospective cohort study was conducted using the PearlDiver database. Patients who underwent TSA and used preoperative testosterone within 3 months of the index procedure were identified and matched 1:4 to controls without testosterone use using propensity score matching. Matching was performed based on age, gender, comorbidities, Charlson comorbidity index, obesity, tobacco use, and hypogonadism to balance the groups. Postoperative complications were assessed at 90 days and five years. Statistical comparisons were made using odds ratios (ORs) with 95% confidence intervals (CIs), and a p -value of <0.05 was considered statistically significant. Results The matched cohort included 677 testosterone users and 2554 controls. There were no statistically significant differences between the testosterone and control groups in 90-day complications such as myocardial infarction (OR 2.52, P = 0.31), pneumonia (OR 0.86, P = 0.70), and deep vein thrombosis (no cases in the testosterone group). Over five years, the testosterone group had a significantly higher risk of periprosthetic joint infection (4.1% vs. 2.4%, OR 1.76, 95% CI 1.10–2.75, P = 0.015), but no differences in revision rates, dislocation, aseptic loosening, or stiffness were observed. Conclusion Preoperative testosterone exposure was associated with a higher risk of periprosthetic joint infection following TSA, but no significant differences were found in major medical complications or revision rates.

Abstract Background: Patients with residual invasive disease after neoadjuvant chemotherapy (NAC) for HER2-positive breast cancer remain at high risk for recurrence even with standard adjuvant trastuzumab emtansine (T-DM1). H2NVAC, a multi-epitope HER2 peptide vaccine, has previously demonstrated the ability to elicit robust and durable immune responses. Here, we assessed the safety and early immunogenicity of H2NVAC in combination with T-DM1 in this high-risk population. Methods: Patients with stage II-III HER2-positive breast cancer and residual invasive disease following NAC and HER2-directed therapy received standard adjuvant T-DM1 alongside six priming doses of H2NVAC administered every 3 weeks. The primary endpoint was the occurrence of dose-limiting toxicity (DLT) within 21 days of the first vaccination, with adverse events graded per CTCAE v5.0. Immunogenicity assessments included HER2-specific T-cell responses measured by IFNγ ELISpot and HER-specific serum antibodies measured by ELISA at baseline and 30 days after the sixth priming dose. Results: 20 patients were enrolled. H2NVAC plus T-DM1 was well tolerated with no DLTs observed. All treatment-emergent AEs were grade 1-2, with fatigue (grade 1 60%, grade 2 5%), peripheral sensory neuropathy (grade 1 35%, grade 2 10%), elevated alkaline phosphatase (grade 1 40%), nausea (grade 1 35%, grade 2 5%), arthralgia (grade 1 30%), and injection-site reactions (grade 1 50%) being most common. Robust vaccine-specific T-cell responses by ELISpot were observed in 94% of evaluable patients, who mounted HER2-specific T-cell responses at 30 days after the sixth priming dose, with a mean 197-fold increase over baseline. Further CYTOF analysis showed a significant decrease in exhausted T-cell phenotypes, with reduced LAG3 and TIM3 expression on both CD4+ and CD8+ T cells. For antibody responses by ELISA, 26% of patients developed HER2 protein-specific antibody responses at this time point. There was no significant increase in antibodies to H2NVAC peptides or to unrelated tumor antigens (p53, IGFBP2, TERT, myoglobin) at 30 days after the sixth vaccine. Ongoing correlative analyses will assess the evolution of immune responses at later time points following completion of T-DM1 therapy. Conclusions: Concurrent administration of H2NVAC with T-DM1 was safe and did not increase toxicity beyond single-agent T-DM1. To our knowledge, this is the first study to demonstrate that a cancer vaccine can be delivered concurrently with an antibody-drug conjugate without increasing adverse effects while still eliciting robust T-cell responses. Ongoing analyses will further define the kinetics and durability of vaccine-induced antibody and T-cell responses at later time points, as well as evaluate the efficacy of H2NVAC in reducing recurrence risk in the randomized phase 2 trial.
