BACKGROUND AND OBJECTIVES: Embolization is part of multidisciplinary brain arteriovenous malformations (AVMs) treatment, yet safety data for novel liquid embolization agents (LEAs) such as Squid and PHIL remain limited. This study reports complications and outcomes from curative embolization using Onyx, Squid, PHIL, and Glue. METHODS: Adult patients with brain AVMs treated with LEAs from July 2015 to December 2022 were reviewed for intraprocedural technical issues, postoperative hemorrhagic, and ischemic complications. Minor (modified Rankin Scale ≤2) and major complication rate (morbidity/modified Rankin Scale >2), mortality, and 6-month angiographic cure rate were evaluated. RESULTS: In total, 135 patients (62.2% male, mean age 41.7 ± 15.1 years) with 206 embolizations (34% Onyx, 18.9% Squid, 17.5% PHIL, 28.2% Glue) were included. Overall, 87.4% procedures were in ruptured AVMs and 84% treated by the transarterial technique (84%). The 6-month angiographic cure rate was 53.3%, higher when nonadhesive LEAs were used than Glue (65.3% vs 17.6%, P < .001). In adjusted analysis, only eloquent location (odds ratio [OR] = 4.4; P = .007) and Glue (OR = 9.1; 95% CI 2.9-28.9, P < .001) were predictors of lower angiographic occlusion rate, whereas size had an inverse correlation (OR = 0.67; P = .019). Technical procedural complications, hemorrhagic, and ischemic rates were 10.2% (2.2% morbidity), 13.1% (3.7% morbidity and 2.2% mortality), and 9.2% (2.2% morbidity, 0% mortality), respectively, regardless of the preferred LEA. Minor, major complications, and mortality rates were 3.7%, 4.4%, and 2.2%, respectively. Hemorrhage was the major contributor to morbidity and mortality, whereas deep venous drainage was an independent predictor of hemorrhage and mortality. CONCLUSION: PHIL and Squid demonstrated complication and angiographic cure rates comparable with Onyx. However, curative embolization of brain AVMs resulted in only moderate angiographic occlusion. Larger multicenter studies with standardized operator protocols, cost-effectiveness assessments, and extended follow-up are warranted to validate these findings.

ABSTRACT Periprosthetic joint infection (PJI) is the most common and difficult to treat form of arthroplasty failure. While treatment with debridement, antibiotics, and implant retention (DAIR) is preferable to one- or two-stage implant exchange based on morbidity and cost, outcomes are not successful in all cases selected for this management strategy. DAIR is currently recommended when infection is perceived to be in an “acute” phase, based on symptom duration; despite this selection strategy, DAIR failure rates are high. A more objective means of predicting DAIR success could improve patient outcomes by limiting DAIR failures. To explore this possibility, advanced proteomic analysis of sonicate fluid samples from 95 subjects with PJI was performed using proximity extension assay (PEA), with 77 samples additionally undergoing complementary proteomics analysis with liquid chromatography with tandem mass spectrometry (LC-MS/MS). Sparse partial least squares differentiation analysis (sPLS-DA) separated samples from patients who underwent DAIR with known outcomes ( n = 19) into successful or unsuccessful groups, predicting DAIR surgical outcome (area under the curve [AUC]: 1; mean “leave one out” AUC: 0.6). Proteins predictive of DAIR surgical outcome were significantly enriched for the “protein repair” Gene Ontology (GO) pathway ( P -adj = 0.02). Additionally, proteomic signatures associated with symptom duration in PJI categorized samples into short and long symptom duration PJI. In summary, an investigation of 7,261 unique human proteins separated PJI-associated samples based on symptom duration and identified a proteomic profile predictive of DAIR success. IMPORTANCE Chronic infections are generally understood to last months to years, with acute infections lasting days to weeks. The transition from acute to chronic infection is, however, poorly understood. Periprosthetic joint infection (PJI) has been considered more challenging to treat when “chronic” than when “acute.” A surgery preferred for its recovery time and cost—debridement, antibiotics, and implant retention (DAIR)—is recommended for PJI management when symptom duration is short; yet, even in this select patient group, DAIR is associated with a high treatment failure rate. A means to better identify those predicted to have a successful outcome if they undergo DAIR is needed. Here, over 7,000 proteins from human clinical PJI samples were measured and shown to be able to separate samples based on symptom duration. Importantly, a proteomic profile predictive of DAIR success was identified.

ABSTRACT Background & Aims Pregnancy can be a complex and risk filled event for women with inflammatory bowel disease (IBD). High‐quality studies in this population are lacking, with limited data on medications approved to treat IBD during pregnancy. For patients, limited knowledge surrounding pregnancy impacts pregnancy rates, medication adherence, and outcomes. Limited provider knowledge leads to highly varied practices in care affected by local dogma, available resources, individual interpretation of the literature, and fear of harming the fetus. The variations in guidelines by different societies and countries reflect this and lead to confusion for physicians and patients alike. The Global Consensus Consortium is a group of 39 IBD and content experts and 7 patient advocates from 6 continents who convened to review and assess current data and come to an agreement on best practices based on these data. Methods The GRADE (Grading of Recommendations Assessment, Development, and Evaluation) process was used when sufficient published data were available and the RAND process in those instances where expert opinion was needed to guide consistent practice. Recommendations were informed by the guiding principle that maternal health best supports infant health. Results The topics were divided into ten categories with 34 GRADE recommendations and 35 consensus statements. Conclusions Overall, the goal of the group was to provide data‐driven and practical guidance to improve the care of women with IBD around the globe based on the best available research.

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 Aims Patients with end-stage renal disease (ESRD) and atrial fibrillation present a challenge for thromboembolic prevention, given their elevated risks of both thromboembolism and bleeding. Anticoagulants carry a higher bleeding risk in this population without clear evidence of thromboembolic benefit. This study aims to define the role of left atrial appendage occlusion (LAAO) as a preventive strategy for patients with ESRD. Methods and results A systematic literature review was conducted to identify studies reporting outcomes in patients with ESRD who underwent LAAO. Meta-analyses of aggregate and individual patient data were performed to evaluate acute and long-term outcomes and compare them with those of patients without ESRD. Seventeen studies reporting data from 24 127 patients, including 1047 with ESRD, were included. Procedural complications were more common in patients with ESRD (RR 2.23; P = 0.02), with a pooled rate of 4% (95% CI, 1–9%). There was no significant difference in thromboembolic event rates during follow-up between the groups (IRR 1.44; P = 0.16), but major bleeding incidence was higher among patients with ESRD (IRR 1.84; P &lt; 0.01). Individual patient-level data from seven studies comprising 4745 patients (268 with ESRD) were obtained and analysed. Similarly, there was no significant association between ESRD and stroke/TIA incidence (HR, 1.22; 95% CI, 0.66–2.26), but major bleeding was higher on patients with ESRD (HR, 1.65; 95% CI, 1.01–2.69). Conclusion LAAO represents a feasible option for thromboembolic prevention in patients with ESRD, although these patients have an increased risk of complications and bleeding.

Introduction: Reversible and irreversible nephrotoxicity are known complications of tacrolimus. Approaches to reduce the incidence of nephrotoxicity include the reduction or avoidance of tacrolimus but must be weighed against risk of rejection. Infrequently, basiliximab has been used outside of the induction period to facilitate temporary tacrolimus cessation in the setting of acute kidney injury (AKI). Objective: The primary objective of this study was to describe renal recovery after temporary tacrolimus cessation with non-induction basiliximab (NIB) compared to a matched cohort. Methods: We conducted a single-center study of adult cardiothoracic transplant recipients that received basiliximab beyond post-operative day 7 for temporary tacrolimus cessation in the setting of AKI between January 2019 and November 2023 and matched them to acontrol cohort. Results: Twelve patients underwent temporary tacrolimus cessation with NIB. In total, 7 (58%) patients achieved initial renal recovery at tacrolimus resumption compared to 15 (42%) patients in the matched cohort at an equivalent time point. No difference between treated rejection (17% vs. 19%, p = 0.80) or infection (75% vs. 50%, p = 0.32) was observed between tacrolimus cessation and its matched cohort. Conclusions: The use of NIB for tacrolimus cessation can allow for potential renal recovery after an AKI or in patients at risk of AKI. This approach does not appear to significantly increase the risk of rejection but may increase the risk of infection in the long term.

Acute respiratory distress syndrome (ARDS) is a common and highly heterogeneous condition in the critically ill. The association between hyper- and hypo-inflammatory subphenotypes and clinical outcomes has generated significant interest in precise ARDS management. The value of identifying biomarkers to guide treatment and enrollment in future ARDS trials is undisputable. We describe multiple factors complicating the search for subphenotypes and their treatable traits. The observed heterogeneity seen in the clinical course of ARDS is dynamic and influenced by factors beyond lung pathophysiology, including variations in the delivery of best critical care practices, patient comorbidities, and functional status, and patient or family preferences. Current subphenotype definitions lack strong biological plausibility and without clear evidence of benefit from targeted treatments, their use in clinical practice is currently unwarranted.

ABSTRACTBackgroundRecent data demonstrate increased incidence of Infantile hemangioma (IH) over the past several decades. However, little is known about current trends in healthcare utilization and medication prescribing in patients with IH in the United States (US), particularly since the discovery and uptake of beta‐blockers as standard of care treatment.MethodsWe examined US ambulatory visits in infants (age ≤ 1 years) with any hemangioma (International Classification of Diseases [ICD] 9th Revision codes 228.00, 228.01, or 228.09 in the National Ambulatory Medical Care Survey [NAMCS] 2009–2015, and ICD 10th Revision code D18.0 in the NAMCS 2016–2019). We further trended the prescription of topical and systemic IH treatments during this period.ResultsYears of visit were bundled into 5‐year bins to minimize standard errors for the trend tests. The number of visits related to IH significantly increased from 878,725 (95% CI: 439,376–1,318,074) in 2009–2013 to 1,431,913 (95% CI: 940,036–1,923,790, p = 0.022) in 2014–2019. The number of visits with resulting timolol prescription concurrently significantly increased from 16,279 (95% CI: 0–40,600) to 424,845 (95% CI: 380,786–468,903, p < 0.001), while the increase in the number of propranolol prescriptions was nonsignificant (from 162,323 [95% CI: 0–331,537] to 208,139 [95% CI: 0–558,709], p = 0.652).ConclusionsThe US healthcare utilization for IH has been on the rise between 2009 and 2019, likely owing to increased awareness, earlier diagnosis, and enhanced therapies. While topical beta‐blocker prescriptions have significantly increased during that period of time, systemic beta‐blocker prescription rates have not.
