Abstract Effective communication during handoffs and transitions of care is crucial, as over 50% of sentinel patient events are due to communication gaps, according to the Joint Commission. In our open multi-specialty Intensive Care Unit (ICU) at a tertiary care center, we noticed variability in handoff practices leading to provider dissatisfaction, delays in care and increased potential for errors. To address this, we developed and implemented a standardized handoff procedure. METHODS: A multi-disciplinary team comprised of fellow physicians, nursing and advanced practice provider (APP) leadership conducted an online anonymized baseline survey (B) in December 2023 in our open mixed ICU assessing multidisciplinary provider satisfaction in the process of transitioning patients out of the ICU. Based on this, we identified areas for improvement in the ICU transfer-out process, focusing on communication methods and handoff standardization. Between February and June 2024, we designed and posted signage near provider work areas to clearly designate the primary team based on the level of care and co-managing specialties. We also developed electronic record-based template dot phrases based on the I-PASS format to help standardize information provided during handoff, and ICU team members were educated on the use of the same. Post-implementation (PI) surveys were anonymously conducted in June 2024 to assess the impact of changes, with data analysis comparing pre- and post-implementation metrics, and regular feedback meetings facilitated iterative improvements. RESULTS: We received 40 survey responses (B =20 and PI=20). In the baseline survey, 65% identified room for improvement, particularly with the timing of provider handoffs, inconsistencies in transfer documentation, and clarity on the responsible medical team. Post-implementation survey results showed a 15% improvement with 80% reported no problems during the process, and 85% rated the clarity of the process as “very clear” and “clear,” with 15% neutral. Regarding staff communication, 90% rated it as “good” to “very good,” with 5% neutral. Dot phrase utilization was deemed “very helpful” to “helpful” by 54%, while 46% were neutral. The majority (95%) reported no challenges during the transfer-out process, and 80% were satisfied with the initiative's implementation. CONCLUSION: Our study highlights the impact of a multimodal approach in improving the process of ICU transitioning patients. We were able to improve the primary team identification with posted signage in the ICU.Using computer template-based dot phrases, we were also able to successfully improve satisfaction with the sign out process at time of transition out of the ICU level of care.

AimsPrevious studies have highlighted differences in the risk of periprosthetic fractures (PPFs) in patients undergoing total hip arthroplasty with either a cemented taper slip (TS) stem or a composite beam (CB) stem. This biomechanical study explored the occurrence of PPF around these stems, and the protective effect of adding a 16-gauge prophylactic calcar or diaphyseal wire to the TS stems to increase the resistance to torque as a potential way to prevent these fractures.MethodsA total of 21 TS stems (eight alone, six with calcar wiring, and seven with diaphyseal wiring placed 2 cm distal to the lesser trochanter) and seven CB stems were cemented into standard sawbones. The peak torque at failure was measured using a servohydraulic test machine, and the fracture location was recorded. An a priori power analysis determined that seven specimens per group were needed to detect a 30 Nm difference with 90% power, assuming a 14.8 Nm SD in peak torque between groups. Comparisons were performed using paired t-tests.ResultsCB stems exhibited a significantly higher mean peak torque at failure (205.3 Nm (SD 26.9)) than TS stems (159.5 Nm (SD 17.4); p = 0.012), calcar-wired TS (148.2 Nm (SD 38.6); p = 0.031), and diaphyseal-wired TS (164.9 Nm (SD 21.5); p = 0.027). This study did not demonstrate that wired-TS stems had a higher peak torque at failure than non-wired TS stems. Additionally, calcar wiring was not found to be stronger than diaphyseal wiring (p = 0.400). Four CB fractures occurred distal to the stem, whereas all TS fractures occurred at the mid-stem, simulating a Vancouver type B fracture. Interestingly, adding the diaphyseal wire shifted the fracture location more distally in four of the seven stems (p = 0.070).ConclusionIn this model, CB stems had greater resistance to torque than TS stems, which may explain the lower risk of PPF. Adding calcar or diaphyseal wires to the TS stems resulted in no significant change in peak torque to fracture. CB cemented stems should be considered in patients at high risk of PPF.Cite this article: Bone Joint J 2025;107-B(5 Supple A):32–37.

Abstract Gliomas are highly malignant brain tumors with poor prognosis and short survival. Nicotinamide adenine dinucleotide (NAD+) plays a critical role in cancer progression, yet anti-cancer therapies targeting NAD+ synthesis have had limited clinical success due to an incomplete understanding of its mechanisms. Here, we demonstrate the essential role of the NAD+ synthase nicotinamide mononucleotide adenylyltransferase (NMNAT) in glioma progression and its novel contribution to nuclear atypia. Analysis of the patient glioma transcriptomics dataset (GAPIA) indicated a strong correlation between high NMNAT transcription levels and poorer disease-free survival in low grade glioma (LGG) and glioblastoma multiforme (GBM). Utilizing quantitative statistical analysis to assess the size and circularity of about 3 million cells in glioma tissue samples from 19 patients, we identified the significant association between NMNAT1 protein level and increased nuclear atypia in different types of gliomas. Mechanistic studies in human glioma cells and a Drosophila glial neoplasia model revealed that NMNAT enhances glioma growth by promoting NAD+-dependent post-translational modifications poly(ADP-ribosyl)ation (PARylation) and deacetylation of p53, thereby attenuating the pro-apoptotic activity of p53. Additionally, NMNAT1 disrupts nuclear lamina integrity by altering lamin A/C distribution, further contributing to nuclear atypia and glioma progression. These findings uncover a novel tumorigenic mechanism involving NMNAT's regulation of nuclear architecture and NAD+-mediated metabolic signaling pathways, highlighting its roles in glioma growth and nuclear atypia. This study underscores NMNAT as a potential therapeutic target in glioma treatment.

Abstract Background: Effective treatments (Tx) are needed for MTAP-del cancers (10-15% of all cancers). BMS-986504 (formerly MRTX1719) is a potential first-in-class MTA-cooperative protein arginine methyltransferase 5 (PRMT5) inhibitor that selectively binds to the PRMT5-MTA complex, a synthetic lethal target in MTAP-del but not MTAP-wild-type cells. In the first-in-human phase 1/2 CA240-0007 study, BMS-986504 was well tolerated and showed clinical activity in heavily pretreated pts across multiple advanced solid tumors with homozygous MTAP-del. Here, we report results of exploratory PD analyses of PRMT5 inhibition with BMS-986504 in CA240-0007. Methods: Pts with advanced, unresectable or metastatic solid tumors with homozygous MTAP-del received BMS-986504 (50 to 800 mg) in 3-wk cycles. Symmetric dimethylarginine (SDMA) and intron retention are known PD BMs of PRMT5 inhibition. Therefore, PD effects of BMS-986504 were assessed via changes in plasma and tumor SDMA levels (mass spec and IHC), intron retention, and gene expression (RNASeq) based on samples collected at baseline (BL) and cycle 2 day 1 (C2D1). Additional analyses correlating efficacy outcomes with PD results and select mutations at BL were performed in clinically evaluable pts as of 19-SEP-24. Results: Robust PD modulation of the PRMT5 pathway was observed with BMS-986504. Among pts with matched samples (n = 63), median plasma SDMA levels were reduced by 56% from BL (122.6 ng/mL) to C2D1 (53.8 ng/mL). There were dose-dependent reductions in median plasma SDMA with the greatest reductions at 400 mg QD (59.7% [n = 20]), 400 mg BID (61.9% [n = 9]) and 600 mg QD (59.1% [n = 14]). These PD effects were corroborated in the tumor. Median tumor SDMA levels decreased from an HScore of 285 at BL to 0 at C2D1. Consistent with the SDMA decreases, increased intron retention was observed in 9/11 pts with matched samples. BMS-986504 led to downregulation of several gene pathways including DNA repair and mitotic spindle formation, and MYC and E2F targets, as assessed by RNASeq. There was no significant change in expression of MAT2A, PRMT5, or other PRMT genes, suggesting a lack of compensation for PRMT5 inhibition through these genes. Responses were observed with BMS-986504 across EGFR, KRAS, and TP53 mutation subgroups. Additional correlative analyses among BMs and efficacy outcomes will be presented. Conclusions: BMS-986504 demonstrated robust PD effects across multiple doses and solid tumors which is consistent with the proposed mechanism of action. There was a trend of increasing plasma SDMA reduction across doses, with the greatest reductions observed at 400 mg QD and above. Together these results support further investigation of BMS-986504 at 400 mg QD and higher doses as a potential first-in-class synthetic lethal Tx option in pts with advanced solid tumors with MTAP-del.

Abstract The International League Against Epilepsy (ILAE) has updated the operational classification of epileptic seizures, building upon the framework established in 2017. This revision, informed by the implementation experience, involved a working group appointed by the ILAE Executive Committee. Comprising 37 members from all ILAE regions, the group utilized a modified Delphi process, requiring a consensus threshold of more than two thirds for any proposal. Following public comments, the Executive Committee appointed seven additional experts to the revision task force to address and incorporate the issues raised, as appropriate. The updated classification maintains four main seizure classes: Focal, Generalized, Unknown (whether focal or generalized), and Unclassified. Taxonomic rules distinguish classifiers, which are considered to reflect biological classes and directly impact clinical management, from descriptors, which indicate other important seizure characteristics. Focal seizures and those of unknown origin are further classified by the patient's state of consciousness (impaired or preserved) during the seizure, defined operationally through clinical assessment of awareness and responsiveness. If the state of consciousness is undetermined, the seizure is classified under the parent term, that is, the main seizure class (focal seizure or seizure of unknown origin). Generalized seizures are grouped into absence seizures, generalized tonic–clonic seizures, and other generalized seizures, now including recognition of negative myoclonus as a seizure type. Seizures are described in the basic version as with or without observable manifestations, whereas an expanded version utilizes the chronological sequence of seizure semiology. This updated classification comprises four main classes and 21 seizure types. Special emphasis was placed on ensuring translatability into languages beyond English. Its aim is to establish a common language for all health care professionals involved in epilepsy care, from resource‐limited areas to highly specialized centers, and to provide accessible terms for patients and caregivers.

Abstract Purpose: While an addition of immune checkpoint inhibitor (ICI), pembrolizumab, has improved outcomes of patients with TNBC, early-stage TNBC patients with residual cancer burden (RCB) II/III after neoadjuvant chemotherapy in combination with pembrolizumab (NAP) still have poor outcomes. Previously, we demonstrated that intratumoral HLA-DRA expression and interferon-alpha (IFNα) responses were associated with immune-inflamed phenotype and better outcomes in TNBC patients receiving chemotherapy. This study utilized the CosMx™ SMI to investigate in early-stage TNBC treated with NAP. Methods: Of 151 samples from TNBC patients treated with NAP at Mayo Clinic, 8 pre-treatment biopsy samples (5 pCR and 3 RCB II/III were analyzed using the CosMx™ SMI platform. Linear mixed models to assess differential expression (DE), adjusting for hierarchical data structures. DE analyses were expressed as log2-fold changes (logFC), with the Benjamini-Yekutieli method. GSEA and IPA for signaling pathway exploration. Results: 1.7 million cells were identified across 8 samples after stringent quality control. Immune cell profiling revealed higher B cells, plasma cells, plasmablasts, and T cells (CD4 and CD8) in responders, whereas fibroblasts and myeloid cells were enriched in non-responders. DE analysis showed significantly elevated expression of HLA-DRA (logFC 1.955, p<0.001), other MHC class I and II components, and IFNα in responders. Tumor cells in responders exhibited the highest IFNα expression across cell types. GSEA and IPA analysis revealed enrichment in interferon signaling, antigen presentation, and the cGAS-STING pathway, which drives IFNα production. Spatial analysis categorized cells by their proximity to tumor cells: within 50 µm, 50-100 µm, and over 100 µm. T cells, particularly CD8 T cells, showed a distance-dependent distribution, with a higher abundance near tumor cells in responders. CD8 T cell activation scores declined with increasing distance from IFNα-positive tumor cells but remained consistently low near IFNα-negative tumor cells. IFNγ-positive CD8 T cells exhibited higher activation compared to IFNγ-negative cells, with activation levels influenced by proximity to tumor cells. Lastly, MHC expression in tumor cells was examined relative to CD8 T cell proximity. HLA-DRA and CIITA expression decreased as tumor cells were farther from CD8 T cells. Conclusions: This spatially resolved single-cell analysis highlights the pivotal role of tumor-immune interactions in response to pembrolizumab in TNBC. Our data suggest that tumor cells secrete IFNα through the activation of the cGAS-STING pathway, which activates T cells within close proximity, highlighting the potential role of cGAS-STING agonist as well as IFNα signaling and antigen presentation in augmenting TNBC responses to ICIs.

Abstract Allogeneic hematopoietic cell transplantation (allo-HCT) can provide curative treatment for hematologic malignancies but is associated with prolonged lymphopenia that may contribute to an increased risk of infection and relapse, resulting in decreased survival. We hypothesized that patients with rapid and robust CD4 T- and B-cell recovery have improved survival and decreased treatment-related mortality (TRM). A total of 2089 patients were included who underwent first allo-HCT for acute myeloid leukemia/acute lymphoblastic leukemia/myelodysplastic syndrome from 2008 to 2019 reported to the Center for International Blood and Marrow Transplant Research with available CD4 counts at days 100 and 180. Patients (median age, 51 years [range, 2-75]) were categorized into 4 groups based on graft-versus-host disease (GVHD) prophylaxis: ex vivo T-cell depletion (TCD/CD34), posttransplant cyclophosphamide, calcineurin inhibitor alone (CNI), or CNI with antithymocyte globulin. Based upon survival, we could identify optimal cutoff points for CD4+ T cells in pediatric (age of <20 years) patients: 248 × 106/L and 420 × 106/L at days 100 and 180, respectively; and in adult (age of >20 years) patients: 104 × 106/L and 115 × 106/L at days 100 and 180, respectively. In adults, day-100 CD4 count was associated with overall survival (OS), progression-free survival (PFS), and TRM but not relapse, incidence of infections, or chronic GVHD. Similarly, CD4 counts above the cutoff point at day 180 in adults were associated with improved OS, PFS, and TRM but no other outcomes. No clinical associations for CD4 counts were identifiable in pediatric patients. These findings underscore the importance of tailoring transplant strategies for adults to optimize immune recovery and improve patient outcomes.

Background: Total mesorectal excision (TME) remains the gold standard for the resection of rectal cancer regardless of the modality: open, laparoscopic, or robotic. The transanal TME (TaTME) approach has been utilized to overcome the difficulties encountered with the dissection of tumors in the distal pelvis. Recently, a single-port robotic approach (rSPa) was introduced, where three arms and a camera emanate from a 2.5 cm diameter port. This report presents the first experience in the United States combining those two approaches (rSPa TaTME) in rectal cancer, evaluating its safety and oncologic outcomes. Methods: This is a retrospective review of our prospectively maintained rectal cancer database. Patient demographics, tumor characteristics, neoadjuvant treatment, and oncologic and surgical outcomes were recorded. Results: Between May 2022 and August 2024, ten patients (six females, four males) with a median age at surgery of 53 years (range: 38–85) and a mean BMI of 26 (±5) kg/m2 were included for analysis. The median distance of tumors from the anorectal junction was 3.2 cm (range: 2–5.3 cm). All patients had negative margins, with eight complete TME specimens, one near complete, and one incomplete. The mean number of lymph nodes harvested was 24 (±11). The average operative time was 351 (243–411) min. The average length of stay was four days. The ileostomy was reversed in nine out of ten patients. Six patients experienced complications within 30 days of surgery. There were no local or distal recurrences, with a mean follow-up of 20 months (range: 4–30). Conclusions: rSPa TaTME is a unique and innovative method of combining two minimally advanced approaches for the resection of distal rectal cancers, with acceptable surgical and oncologic outcomes.

BACKGROUND: Data registries lack a definitive classification system that distinguishes different locations of colon cancer from one another. OBJECTIVE: To establish an international consensus on the definition of primary colon cancer segment locations. DESIGN: Between December 2022 and June 2023, Delphi survey study was conducted to seek opinions from relevant international experts and eventually develop a consensus definition of each colon cancer segment. SETTING: Three-round online-based Delphi survey study. INTERVENTIONS: Online survey included 17 questions. In the first two rounds, participating experts were asked to rank each statement on a scale of 1–9 (9 is the most relevant). Consensus statements and definitions were revised according to results, obtaining a consensus score of 7–9. During the third round and online meeting, definitions and statements reached a moderate or high consensus(above 4 in more than 70% of participants) were included. MAIN OUTCOME AND MEASURE: Primary goal of our project was focused on precisely localizing the specific segment affected by primary colon cancer, rather than to identify surgical treatment or type of resection needed for particular segment. RESULTS: The first round included 331 experts, 301 (91%) completed the second round, and 295 (98%) completed the final round. Experts strongly supported the use of a “10 cm rule” to describe colon cancer sites at the flexures and anatomical landmarks for other segments. Regarding the definition of rectosigmoid cancer, experts from America and Europe reached a high consensus that the term rectosigmoid as a colon cancer location must be abolished in contrast to experts from Asia. Description of cancers overlapping segments achieved a consensus of 64%. LIMITATIONS: Subjective decisions are based on individual expert clinical experience. CONCLUSIONS: This Delphi survey, the first internationally conducted consensus study, achieved a remarkable level of consensus among a panel of global experts. Ambiguity still exists regarding overlapping lesions. See Video Abstract .
