Background: Transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO) are leading causes of transfusion-related morbidity and mortality. Soluble factors in erythrocyte supernatant may increase risk for these complications. The authors hypothesized that point-of-care allogeneic erythrocyte washing may be an effective intervention to mitigate elevations in soluble factors as well as physiologic responses associated with transfusion-associated respiratory complications in the setting of cardiac surgery. Methods: This is a two-center, nonblinded, randomized clinical trial evaluating point-of-care washed versus standard issue allogeneic erythrocyte transfusions administered during or on the day of cardiac surgery. The primary analysis was performed via modified intention to treat. The primary outcomes assessed were changes in intermediate markers of lung injury as well as cardiopulmonary physiologic responses to erythrocyte transfusion. Secondary outcomes included the duration of intensive care unit and hospital stay, durations of mechanical ventilation and oxygen supplementation, presence of TRALI or TACO, and mortality. Results: Among 154 analyzed patients (81 washed, 73 standard issue), the median age was 66 yr, and 77 (50.0%) were women. The median (interquartile range) number of allogeneic erythrocyte units transfused on the day of surgery was 3.0 (2.0 to 5.0) in the washed erythrocyte group and 3.0 (2.0 to 4.0) in the standard issue group (P = 0.13). No between-group differences were identified in any of the assessed recipient lung injury biomarkers (all P values > adjusted alpha). Durations of intensive care unit stay (median [interquartile range], 3.0 [2.0 to 5.0] vs. 3.0 [2.0 to 4.0] days; P = 0.117) and hospital length of stay (12.0 [9.0 to 17.0] vs. 12.0 [9.0 to 17.0] days; P = 0.801) were similar, as were the number of ventilator-free days at day 28 (27.0 [27.0 to 27.0] vs. 27.0 [26.0 to 27.0]; P = 0.699) and oxygen-free days at day 28 (24.0 [19.0 to 26.0] vs. 24.0 [22.0 to 26.0]; P = 0.400). No significant differences were noted in mortality rate or in incidence rates for TRALI, TACO, and acute kidney injury. Conclusions: Among patients undergoing cardiovascular surgery with high risk of erythrocyte transfusion, point-of-care washing of allogeneic erythrocyte transfusions did not mitigate changes in intermediate markers of lung injury or cardiopulmonary physiologic responses to erythrocyte transfusion and was not associated with improved clinical outcomes.

Abstract Objective The objective of this study was to examine the clinical outcomes during the implementation of a self-administered patient decision-aid (PtDA) for lupus. Methods We provided an effective computerized lupus PtDA in 15 rheumatology outpatient clinics 2019–2024 (including the COVID pandemic). We undertook Organizational Readiness to Implement Change Surveys (ORICs) and Team Learning and Psychological Safety Surveys (TLPSSs) at baseline. The primary study outcome objective measure, percent penetration/reach, was defined as the number of patients who viewed the lupus PtDA at the end of the study, divided by the total number of eligible patients (times 100). We used validated clinical personnel surveys to examine the perceived lupus PtDA appropriateness, acceptability, feasibility, success, and permanence, at 4 months, 12 months and 24 months post-PtDA implementation. Results Among the sites, the clinical personnels’ (n = 184) baseline ORIC commitment and efficacy scores (a 0–5 scale, higher = better) ranged from 3.5 to 4.2, and 3.4 to 4.4, respectively; the TLPSS scores (a 0–7 scale, higher = better) were 3.9–5.5 for internal learning, 3.7–5.6 for external learning, and 4.3–5.5 for psychological safety. The penetration (primary outcome) among 15 geographically diverse US rheumatology clinics ranged from 3% to 44%. We found that the total number of providers in the clinic was positively associated with higher penetration. Clinical personnel–perceived lupus PtDA outcomes were optimal at 4 months (all scale scores ranged from 1 to 5, higher = better): (i) appropriateness, 3.43 (s.d. 0.86); (ii) acceptability, 3.53 (s.d. 0.83); (iii) feasibility, 3.44 (s.d. 0.71); (iv) success, 3.41 (s.d. 0.73); and (v) permanence, 3.22 (s.d. 0.74). Conclusion We implemented a lupus PtDA with varied success rates during the COVID pandemic; more providers were associated with higher clinic penetration. Clinical personnel perceived high lupus PtDA appropriateness, acceptability, feasibility, success, and permanence that persisted up to 24 months.

The NCCN Guidelines for Testicular Cancer provide recommendations for the multidisciplinary approach to the diagnostic workup, treatment, and follow-up for testicular germ cell tumors, including both seminoma and nonseminoma. These NCCN Guidelines Insights discuss the current treatment recommendations and supporting clinical data for seminomas as presented in Version 2.2025 of the NCCN Guidelines for Testicular Cancer.

Ewing sarcoma and osteosarcoma constitute 36% of all primary bone cancers. However, these 2 subtypes represent the most commonly diagnosed bone cancer types in the pediatric and adolescent population. Although still largely unknown, certain genetic mutations, rearrangements, and/or predisposition syndromes likely play a role in the pathogenesis of bone cancer. Osteosarcoma may also develop as a direct result of the long-term side effects of radiation therapy. With the implementation of a multimodality approach to treatment, including multiagent neoadjuvant and adjuvant chemotherapy regimens, targeted therapy options, surgery, and radiation, individuals with Ewing sarcoma and osteosarcoma are showing higher cure rates and improved overall survival. The NCCN Guidelines for Bone Cancer provide a consensus and evidence-based framework for the workup, management, and surveillance of local and recurrent/metastatic disease.

Abstract Purpose/Background Clozapine was approved in the United States (US) using 1989 regulations and knowledge. After 30 years, many sections of the US package insert (PI) are outdated. Methods We comprehensively reviewed the literature to propose PI updates. We present the information in 2 articles. In Part I, we focus on basic pharmacology based on 407 relevant articles. Part II focuses on clinical aspects and pharmacovigilance. Findings/Results Based on more recent expectations of Food and Drug Administration regulations, we reviewed clozapine basic pharmacology including the following: 1) clearance, 2) pharmacokinetics and pharmacodynamics, and 3) monitoring tools. We identified 9 major problems in the basic pharmacological sections of the PI including the following: 1) in vivo studies indicate that clozapine is dependent on CYP1A2 for its metabolism, 2) the minor role of CYP2D6 in clozapine metabolism requires removing the PI recommendation to lower clozapine doses in CYP2D6 poor metabolizers, 3) in nontoxic concentrations CYP3A4 has a minor role in clozapine metabolism and potent CYP3A4 inhibitors lack clinically relevant effects, 4) several drug-drug interactions need to be updated based on recent literature, 5) systemic inflammation may decrease clozapine metabolism and increase the risk of clozapine intoxication, 6) obesity may decrease clozapine metabolism, 7) patients of Asian and Indigenous American ancestry need lower clozapine doses, 8) personalized titration and c-reactive protein monitoring should be considered until prospective studies are available, and 9) the half-life section needs to be modified to acknowledge that single dosing at night is frequent in the US. Implications/Conclusions An improvement in the US clozapine PI may lead to improvement in PIs worldwide.

Abstract Purpose/Background This is the second part of a 2-part article that proposes improving the United States (US) clozapine package insert. Part II focuses on fatal outcomes and the 5 boxed warnings, 4 specifically for clozapine: severe neutropenia, seizure, orthostatic hypotension and myocarditis, and 1 for all antipsychotics (elderly with dementia). Methods US reports to the World Health Organization's global pharmacovigilance database were analyzed from clozapine's introduction to January 15, 2023. Findings/Results The US was the top reporter worldwide for clozapine with 56,003 reports and 9587 associated fatal outcomes. The 4 clozapine boxed warnings were associated with 534 fatal outcomes (218 with severe neutropenia, 131 with seizures, 125 with orthostasis, 36 with myocarditis, 24 with cardiomyopathy, and 0 with mitral valve prolapse). With no boxed warnings, pneumonia was associated with 674 fatal outcomes and increased white blood cell count (a sign of infection) with 596 fatal outcomes. After considering overlaps, pneumonia and increases in white blood cell count explained 900 fatalities, or 9.4% of 9587 fatal outcomes. The Food and Drug Administration continues to focus on severe neutropenia which was associated with only 218 or 2.3% of fatal outcomes, whereas 97.7% of fatal outcomes reported in US clozapine-treated patients had another cause. Implications/Conclusions To help prevent future deaths in clozapine-treated patients, the clozapine package insert should focus on fatal outcomes during infections. Part II offers detailed solutions regarding current boxed warnings and lack of a warning for pneumonia and other infections. The Supplementary Material includes letters of support from 124 non-US clozapine experts from 44 countries/regions who support Parts I and II.

Abstract Outcomes of bispecific antibodies in patients with renal impairment (RI) are not well characterized, given the exclusion of these patients from clinical trials. Herein, we evaluated patients with relapsed/refractory multiple myeloma and RI treated with standard-of-care teclistamab. RI was defined as creatinine clearance (CrCl) <40 mL/min. CrCl <30 mL/min or dialysis dependence was defined as severe RI. Of the 384 included patients, 81 (21%) had RI, including 45 (18%) with severe RI, and 18 (5%) on dialysis. Patients with RI were more likely to be older (median age, 71 vs 67 years; P = .002) and have a higher median number of previous lines of therapy (7 vs 6; P = .04). Rates and severity of cytokine release syndrome (51% vs 59%; grade ≥3: 1.2% vs 1%) and immune effector cell–associated neurotoxicity syndrome (16% vs 13%; grade ≥3: 2.5% vs 2.6%) were similar in patients with and without RI, respectively. Patients with RI had higher baseline and day 30 post-teclistamab grade ≥3 anemia and grade ≥3 thrombocytopenia. Renal function did not worsen after teclistamab initiation in most patients with RI outside of the context of disease progression. Overall response rate (52% vs 56%; P = .61) and survival outcomes (median progression-free survival, 4.6 vs 6.5 months; P = .62) were comparable in patients with and without RI, respectively, after a median follow-up of 9.9 months. No differences in overall survival or non-relapse mortality were noted. Our findings suggest that treatment with teclistamab is feasible in patients with RI, including those on dialysis, with a similar safety and efficacy profile to patients without RI.
