ABSTRACT Anaplastic lymphoma kinase‐positive large B‐cell lymphoma (ALK+ LBCL) is a rare, aggressive subtype of diffuse large B‐cell lymphoma with poor outcomes using standard chemotherapy. In this multi‐institutional retrospective study, we analyzed 39 cases of ALK+ LBCL identified at six US academic centers from 2002 to 2024, with treatment including conventional cytotoxic regimens in frontline and biologically informed and nonchemotherapy‐based strategies in the relapsed setting. Ninety‐two percent of patients received frontline anthracycline‐based chemotherapy; 43% received intensified regimens, and 15% underwent upfront autologous stem cell transplantation (ASCT). Despite these approaches, outcomes remained poor. At a median follow‐up of 5.4 years, median event‐free survival (EFS) was 0.6 years (95% CI, 0.4–0.9), and median overall survival (OS) was 1.5 years (95% CI, 1.3–NR). One‐ and five‐year EFS rates were 28% and 17%, while corresponding OS rates were 72% and 42%, respectively. Advanced stage and high IPI scores were associated with inferior outcomes. Twelve patients received ALK inhibitors, with alectinib showing more durable responses than crizotinib. Lenalidomide and immune checkpoint inhibitors also demonstrated activity, including durable complete responses. Five patients underwent allogeneic stem cell transplantation, with three achieving sustained remission. In conclusion, our findings highlight the limited benefit of chemotherapy, even when intensified or followed by ASCT, and support the integration of biologically targeted therapies, which may have contributed to improved OS in our cohort compared to historical outcomes. Prospective, collaborative studies are needed to better understand disease biology and define optimal use of modern therapies in this rare lymphoma.

ABSTRACT Aims The impact of treatment for tricuspid regurgitation (TR) across different levels of left ventricular ejection fraction (LVEF) remains uncertain. This study aimed to compare the outcomes of surgical and transcatheter tricuspid valve interventions (TTVI) to conservative (medical) management across LVEF categories. Methods and results Patients with severe isolated TR from the TRIGISTRY, a multicentre international registry, were categorized based on LVEF (preserved ejection fraction [pEF]: ≥50%, mildly reduced ejection fraction [mrEF]: 41–49%, and reduced ejection fraction [rEF]: ≤40%). We assessed the impact of treatment modality and procedural success (mild-to-moderate or lower residual TR) on 2-year survival within each LVEF category. Among 2384 patients, 1383 had pEF, 400 had mrEF, and 601 had rEF. Compared to conservative management, surgery (p < 0.0005) and TTVI (p < 0.0001) were associated with a survival benefit in patients with pEF. No significant survival advantage was observed in patients with mrEF (p = 0.28 for both), nor in those with rEF (p = 0.76 and p = 0.22, respectively). Similar results were obtained when surgical and transcatheter interventions were grouped (p < 0.0001, p = 0.17 and p = 0.29 in patients with pEF, mrEF and rEF, respectively). Patients with residual TR after TTVI exhibited a trend toward worse survival compared to those managed conservatively across all LVEF categories (p = 0.47, p = 0.33 and p = 0.008 in pEF, mrEF and rEF, respectively). Conclusions Transcatheter tricuspid valve intervention, whether surgical or transcatheter-based, was associated with improved survival in patients with pEF but not in those with mrEF or rEF. Residual TR remained a significant prognostic factor across the entire LVEF spectrum. These findings highlight the need for careful patient selection when considering TTVI in individuals with rEF.

Abstract Purpose No consistent recommendations exist on how best to educate pharmacists to facilitate implementation of new evidence-based practices. This study aimed to determine whether spaced learning was more effective than traditional education when learning a new evidence-based practice (β-lactam therapeutic drug monitoring, or TDM). Summary β-lactam TDM was implemented in a phased fashion at Mayo Clinic in Rochester. Two go-lives took place, separated by 6 months, which allowed for a natural experiment to test education delivery methods (traditional education in the first go-live group of pharmacists vs spaced learning in the second go-live group of pharmacists). Each group received the same base educational package, with pharmacists in the spaced learning group also offered monthly in-person sessions for 6 months before go-live to discuss key considerations and cases with experts. There was no difference between the spaced learning group and the traditional education group when assessing appropriate use of TDM as defined by (1) appropriate patient selection; (2) correct ordering of laboratory testing; (3) appropriate clinical action; and (4) completed documentation. Assessments of secondary knowledge transfer also showed no difference between the groups. Pharmacists in the different education groups had similar satisfaction scores related to the effect and utility of the education. Both spaced learning and traditional education were part of a comprehensive implementation plan for β-lactam TDM, which might have influenced the outcomes. Spaced learning for future pharmacist education efforts needs further study. Conclusion As part of a greater β-lactam TDM implementation effort, altering the education delivery method did not impact the degree of knowledge transfer.

Abstract Background and Aims The TRISCEND II trial demonstrated superior clinical benefits for patients with ≥severe tricuspid regurgitation (TR) treated with the EVOQUE transcatheter tricuspid valve replacement (TTVR) system plus medical therapy vs medical therapy alone. This work reports 1-year and 18-month outcomes in patients stratified by baseline TR severity. Methods The multicentre, prospective TRISCEND II trial enrolled 400 patients with symptomatic, ≥severe TR, and randomized 2:1 to TTVR (n = 267) or control (n = 133). In a post hoc analysis, patients were stratified into severe TR (n = 172) and massive/torrential TR (n = 220) cohorts. Clinical and quality-of-life outcomes were reported at 1 year, with Kaplan–Meier estimates for all-cause mortality and heart failure (HF) hospitalization assessed at 18 months. Study oversight included an independent echocardiographic core laboratory, clinical events committee, and data safety monitoring board. Results One year after TTVR, TR was ≤mild in 95.2% of severe TR and 95.3% of massive/torrential TR patients. The primary safety and effectiveness endpoint (win ratio) favoured TTVR over control regardless of baseline TR severity: severe {1.64 [95% confidence interval (CI): 1.11, 2.43]} and massive/torrential [2.20 (1.55, 3.14)]. At 18 months, TTVR patients had similar mortality to controls [rate difference: severe 0.2% (−11.6, 11.9), massive/torrential −5.8% (−17.6, 6.0)], whereas HF hospitalization rates favoured TTVR in the massive/torrential cohort [vs control, severe 9.8% (−3.0, 22.7), massive/torrential -15.2% (−28.9, −1.5)]. Conclusions Patients with ≥severe TR benefit from TTVR, experiencing improvements in TR severity, functional capacity, and quality of life regardless of baseline TR severity, with a signal for greater benefit in patients with more advanced disease.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive and chemo-resistant sarcomas with poor survival rates. Loss of CDKN2A or P53 following NF1 disruption is a key event in MPNST development. Here, we used CRISPR-Cas9 somatic tumorigenesis in mice to identify transcriptomic and metabolomic features distinguishing CDKN2A - versus P53 -deleted MPNSTs. Convergent, multiomic analyses revealed that CDKN2A -deleted MPNSTs are especially dependent on the pentose phosphate pathway (PPP) and NADPH metabolism for growth and viability. Disruption of glucose-6-phosphate dehydrogenase (G6PD), the PPP rate-limiting enzyme, slowed CDKN2A -deleted MPNST growth and sensitized MPNSTs to standard-of-care chemotherapy. Knockdown of the redox-regulated transcription factor NRF2 slowed MPNST growth and decreased G6PD transcription. Analysis of patient MPNSTs identified a NRF2 gene signature correlating with tumor transformation. Furthermore, G6PD and NRF2 expression in PanCancer TCGA samples correlates with patient survival. This work identifies NRF2-PPP dependency as a targetable vulnerability in these difficult-to-treat MPNSTs, particularly in the NF1/CDKN2A -deleted majority.

The NCCN Guidelines for Uterine Neoplasms provide recommendations for diagnostic workup, clinical staging, and treatment options for patients with endometrial cancer and uterine sarcoma. The NCCN Cervical Uterine Panel meets at least annually to review comments from reviewers within their institutions; examine relevant new data from publications, abstracts, and recent FDA approvals; and reevaluate and update recommendations. These NCCN Guidelines Insights summarize the panel’s deliberations on the new FIGO 2023 staging system and updates on the new systemic therapy recommendations for the management of endometrial cancer.

While hormonal changes have been recognised to influence seizure control and have been studied in association with menstrual cycles and pregnancy, there is a paucity of data on the menopause transition in epilepsy. Given the known effects of sex steroid hormones on neuronal excitability, their endogenous fluctuations during perimenopause, as well as menopause hormone treatments, may alter seizure control. Epilepsy may also be associated with premature ovarian insufficiency and early menopause. This is especially important for epilepsy-related comorbidities, for which menopause can constitute a second hit, such as osteoporosis. Additional considerations for females with epilepsy across the menopause continuum include changes in antiseizure medication clearance and potential interactions with menopausal hormone therapy or other concomitant medications. This comprehensive review summarises the currently available literature on epilepsy and menopause, highlights gaps in knowledge, and underscores the need for research efforts, particularly longitudinal studies investigating the menopause transition.

ABSTRACT Background Risk for medication error increases during care transitions. Error susceptibility increases in pediatrics due to age and weight‐based dosing. Governing bodies acknowledge errors endanger patients, and transplant pharmacotherapy experts are mandated by the Center for Medicare and Medicaid Services (CMS). Pharmacist‐led medication histories reduce errors; however, pharmacists' roles in the transitions of care between transplant centers are unaddressed by CMS. We assessed the impact of transplant pharmacist involvement in medication histories for pediatrics transitioning between transplant centers. Methods Pediatric patients pre‐ or post‐heart transplant transitioning to our center were proactively identified. Transplant pharmacists conducted medication histories by phone with caregivers and tracked discrepancies between existing medication lists and interview responses. Descriptive statistical analyses were completed. Results Of 27 patients identified, seven caregivers were uncontactable, one declined participation, and 19 underwent transplant pharmacist medication history. Medication list errors were detected in 100% of patients ( n = 19), with a median [IQR] of 5 [3–11] issues per patient. Of 122 issues, 72 (59%) were inaccurate or missing data, 17.2% ( n = 21) listed stopped drugs, 9.8% ( n = 12) revealed incorrect administration routes, 7.4% ( n = 9) were duplicate medications, and 6.6% ( n = 8) of errors were medications needing to be added. Corrections included updating 84 inaccuracies (68.8%); removing/adding drugs (30 [24.6%] and 8 [6.6%], respectively); and team communication. Conclusions Complex dosing strategies in pediatrics confer error vulnerability. Designing transition of care processes with transplant pharmacist involvement in medication histories can assist in ensuring medication list accuracy, thereby improving pediatric patient safety.

Abstract OBJECTIVE AND SCOPE A panel of clinicians, subject‐matter experts, and guideline methodologists convened by the Alzheimer's Association conducted a systematic review and formulated evidence‐based recommendations for using blood‐based biomarkers (BBMs) in the diagnostic workup of suspected Alzheimer's disease (AD) within specialized care settings. The scope focuses on individuals with objective cognitive impairment, including those with mild cognitive impairment (MCI) or dementia, who are undergoing evaluation by providers trained and experienced in memory disorders, where AD is the suspected underlying etiology. METHODS The panel conducted a systematic review to assess the diagnostic accuracy of BBMs in detecting AD pathology. The BBMs of interest included plasma phosphorylated‐tau (p‐tau) and amyloid‐beta (Aβ) tests measuring the following analytes: p‐tau217, ratio of p‐tau217 to non‐p‐tau217 ×100 (%p‐tau17), p‐tau181, p‐tau231, and ratio of Aβ42 to Aβ40. The reference standard tests included cerebrospinal fluid (CSF) AD biomarkers, amyloid positron emission tomography (PET), or neuropathology. The panel applied the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to assess the certainty of the evidence and the GRADE evidence‐to‐decision (EtD) Framework to develop its recommendations. RECOMMENDATIONS The key recommendations in this Clinical Practice Guideline (CPG) are: (1) BBM tests with ≥90% sensitivity and ≥75% specificity can be used as a triaging test and (2) BBM tests with ≥90% sensitivity and specificity can serve as a substitute for amyloid PET imaging or CSF AD biomarker testing in patients with cognitive impairment presenting to specialized care for memory disorders. The panel cautions users of this guideline that there is significant variability in diagnostic test accuracy and many commercially available BBM tests do not meet these thresholds, especially using a single cutoff. Additionally, these tests do not serve as a substitute for comprehensive clinical evaluation by a healthcare professional and should be used only as part of a full diagnostic workup of patients with cognitive impairment presenting to specialized care settings, and with careful consideration of pretest probability of AD pathology. CONCLUSIONS AND PRACTICAL IMPLICATIONS This CPG provides performance‐based, brand‐agnostic recommendations for the use of BBMs in the diagnostic workup of suspected AD within specialized care settings. By linking recommendations to a systematic review and associated living updates, and using a robust and transparent methodology, the guideline ensures scientific rigor, adaptability, and sustained relevance as evidence evolves. Clinicians are encouraged to stay informed about emerging paradigms—such as biomarker combinations or ratios and multi‐threshold testing—that may further refine the diagnostic accuracy of BBMs as the field evolves.
