ABSTRACT Key performance indicators (KPIs) are quantifiable measures that describe critical success factors of an organization. Their vital role in ensuring the delivery of quality health care services necessitates the development of KPIs relevant to inpatient clinical pharmacy practice. This opinion paper from the American College of Clinical Pharmacy (ACCP) Clinical Administration Practice and Research Network (CADM PRN) describes the rationale, methodology, and outcomes of a consensus process to identify a focused set of inpatient/acute care clinical pharmacy KPIs. Leveraging a modified Delphi approach, the CADM PRN convened an Expert Panel of clinical pharmacy leader members to build a consensus‐driven set of KPIs reflecting clinical, operational, patient‐centered, and financial contributions of clinical pharmacists in the inpatient/acute care setting. From a previous ACCP White Paper, a total of 15 KPIs were identified across four domains: (1) clinical practice and patient safety, (2) clinical outcomes and readmissions, (3) medication education and patient engagement, and (4) financial and operational value. The CADM PRN posits that the establishment and implementation of standardized KPIs are essential for measuring and demonstrating the value of clinical pharmacy services in modern health care, offers pragmatic, consensus‐based KPIs for evaluating clinical pharmacy services supporting resource justification, and advancing the visibility and impact of pharmacists in acute care practice. As hospitals shift toward value‐based care, robust KPI frameworks will be critical for optimizing patient outcomes, supporting financial sustainability, and justifying appropriate staffing. Future efforts should focus on pilot testing, addressing implementation barriers, and achieving broader acceptance for KPIs across the profession.

PURPOSE Deficient mismatch repair/microsatellite instability (dMMR, MSI-H) in biliary tract cancers (BTCs) is observed in 1%-5% of tumors. MSI-H across solid tumors has demonstrated durable response to immune checkpoint inhibitors (ICIs) regardless of the anatomic location. Here, we describe clinical outcomes and surgical conversion of MSI-H BTC treated with ICIs. Patients and Methods We conducted a multicenter, retrospective analysis of BTC patients with dMMR/MSI-H between 2017 and 2024 at Mayo Clinic, University of Michigan, and University Hospitals Seidman Cancer Center. Outcomes of interest were surgical resection rate, rate of pathologic response, 2-year overall survival (OS; time from initiation of treatment to death/last follow-up), and time to treatment discontinuation (TTD; time from initiation of treatment to cessation because of any cause). Analyses were descriptive. RESULTS Thirty patients with MSI-H BTC were identified: 19 with cholangiocarcinoma, three with gallbladder cancer, and 8 with BTC undefined. The median age at diagnosis was 61.5 years (range, 26-86). Twenty-six (86.7%) patients had advanced stage at diagnosis. Twenty-seven patients (90%) received first-line systemic therapy, and 13 (48.1%) continued onto second line. Six patients (23.1%) were restaged to resectable from advanced disease after ICI therapy and underwent resection; all remained recurrence-free at last follow-up. Of these six patients, 3 (50%) achieved a pathologic complete response. Among those receiving first-line therapy, the median TTD was 9.9 months (95% CI, 5.7 to 14.5 months) and the 2-year OS was 73% (95% CI, 56% to 94%). CONCLUSION ICI therapy in patients with MSI-H BTC demonstrated durable response and downstaged some BTC to a resectable stage. dMMR/MSI-H should be performed up-front to guide treatment decisions.

Abstract Background Alzheimer’s disease (AD) is clinicopathologically heterogeneous. A proportion of patients living with AD present clinically at a younger onset of cognitive symptoms before 65 years old and/or non-amnestic clinical syndromes. Neuropathologically, corticolimbic distribution of neurofibrillary tangle pathology occurs on a continuum with some cases having greater cortical tau pathology relative to limbic regions and others with relatively restricted accumulation in limbic structures. These patterns of corticolimbic tangle distribution are associated with clinical presentation and age at onset. This study sought to examine protein expression differences across the spectrum of clinicopathologic heterogeneity using the NULISA targeted proteomics platform. Methods A series of thirteen neuropathologically diagnosed AD cases from Mayo Clinic prospectively followed research studies were selected to reflect heterogeneity of clinical syndromes and corticolimbic distribution of tangle pathology. Frozen postmortem brain tissue samples were isolated from inferior parietal cortex and homogenized in RIPA buffer for analysis using Alamar Biosciences’ NULISA CNS disease 120 panel. Applying a conservative detection threshold of 75% level of detection for the novel application of NULISA in human brain, we evaluated levels of 69 of 129 protein targets across samples. We examined associations between age at onset cognitive symptoms and corticolimbic distribution of tangles (CLix) separately with individual protein targets using linear regression analysis. Results AD cases with a younger age at onset had higher measured levels of ubiquitin, while older age was associated with higher levels of total tau, CRH, and NPTX2. Investigations of corticolimbic heterogeneity revealed AD cases with lower CLix score (i.e., cortical predominant distribution of tau) had higher measured p-tau181, p-tau231, ubiquitin, and p62. AD cases with higher CLix (i.e., relative cortical sparing) had higher levels of total tau, CRH, NPTX2, MDH1, and HBA1. Brain-derived total tau consistently showed a stronger association in both models. Conclusion This work demonstrates the utility of postmortem proteomics for investigating biomarkers associated with AD clinicopathologic heterogeneity. We observed proteomic differences in synapse integrity, tau post-translational modification, and ubiquitination associated with age at symptomatic onset and corticolimbic distribution of tangle pathology.

ABSTRACT Introduction Chronic gastroduodenal disorders remain challenging to manage, and new diagnostic approaches are needed to better delineate underlying causes and guide therapeutic decisions. Body Surface Gastric Mapping (BSGM) technologies combine high‐resolution gastric myoelectrical activity measurements with symptom and psychological profiling to provide mechanistic insights into gastric motor and sensory dysfunction. An International Working Group convened to derive the first consensus classification of BSGM phenotypes (the “Auckland Classification”). Methods A Technical Group conducted a systematic literature and clinical database review to identify objective test biomarkers and candidate disease mechanisms. Evidence was synthesized across 50 studies (primarily in gastroparesis, chronic nausea and vomiting, and functional dyspepsia), and BSGM phenotypes were mapped to existing treatment guidelines. Subsequently, iterative review and development of consensus was performed by a Consensus Group composed of international clinical experts familiar with BSGM. Eleven statements underlying the classification were then derived and circulated as a final survey to establish agreement. Results Six BSGM phenotypes were endorsed: three defined by myoelectrical abnormalities (Dysrhythmic, High Frequency, and Low Meal Response) and three by characteristic symptom associations (Sensorimotor, Continuous, and Delayed Onset Symptoms). Published studies plausibly linked these phenotypes to mechanisms including interstitial cell of Cajal depletion, vagal impairment, hypomotility, visceral hypersensitivity, gut‐brain dysregulation, and small bowel dysfunction. Phenotypes were also mapped to existing mechanism‐based treatment guidelines. Ten out of the eleven statements had > 80% agreement. Conclusions The Auckland Classification, derived by international consensus, presents a structured framework for BSGM‐defined patient phenotypes. Evidence and mechanism‐based treatment options are suggested for each phenotype to provide a foundation for research, further validation, and a pathway for integrating BSGM into clinical care.

ABSTRACT Background Disparities in management of atrial fibrillation in rural and urban hospitals across the U.S. have been reported. However, studies investigating disparities regarding outcomes and complications after left atrial appendage occlusion (LAAO) based on hospital location are lacking. Objective To evaluate differences in outcomes and complications related to LAAO among rural and urban hospitals. Methods The National Inpatient Sample was used to identify patients who underwent LAAO implantations in the U.S. from 2016−2020. Study endpoints assessed included inpatient complications, outcomes, and resource utilization after LAAO procedures among rural and urban hospitals. Results From 2016−2020, there were a total of 87 315 and 1985 LAAO device placements in urban and rural hospitals, respectively. Baseline characteristics were similar among both groups, with a few exceptions. After multivariable adjustment for confounders, odds of inpatient complications and mortality were similar among both groups. However, rural LAAO recipients experienced greater rates of discharge to an acute care facility (3.3% vs 2.4%, p = 0.01), as well as lower costs (aOR: 0.58, 95% CI: 0.49–0.69) and length of stay (aOR: 0.89, 95% CI: 0.81–0.98). Conclusions A majority of LAAO implantations occurred in urban hospitals in the U.S. Baseline characteristics and adjusted odds of inpatient complications and mortality were similar in rural and urban recipients. However, important differences were described regarding resource utilization and disposition. Further investigation into the specific factors driving these inequities is encouraged to promote improved access to and outcomes of cardiovascular care for rural residents.

Through a Delphi process, all 33 panelists reached consensus on topics relating to MRI reporting of knee meniscus lesions, demonstrating that interdisciplinary and multi-institutional standardization is possible.

Abstract Background Cholangiocarcinoma (CCA) is an aggressive primary liver cancer with remarkable molecular heterogeneity. Mutations in SWI/SNF chromatin remodeling components occur in > 20% of CCA cases, with ARID1A and PBRM1 being significantly co-mutated. However, how the dual loss of these subunits reshapes chromatin architecture and drives oncogenic programs remains unclear that we aimed to address by profiling SWI/SNF redistribution, chromatin accessibility, 3D chromatin structure, and transcriptome in a dual Arid1a/Pbrm1 knockout mouse model. Methods CCA was induced in Cas9 knock-in mice via biliary instillation of myr-AKT along with sgRNAs targeting Arid1a and Pbrm1, generating APAC cell line. AC cell line was derived from mice receiving myr-AKT alone. Isogenic dual knockout (AC-sgAP) and control (AC-NT) lines were then generated from AC cells. Multi-omics profiling included ChIP-seq for SMARCA4/BRG1 and DPF2, ATAC-seq, RNA-seq, and Hi-C. Results ChIP-seq revealed that AC-sgAP cells showed decreased BRG1 binding (9,217 vs. 20,769 peaks) but increased DPF2 binding (7,527 vs. 2,068 peaks) and co-occupancy (5,037 vs. 1,888 peaks) compared to AC-NT. In contrast, APAC cells exhibited depletion of both BRG1 (12,994 peaks) and particularly DPF2 (146 peaks) with minimal overlap (68 shared peaks). Genome-wide accessibility profiling demonstrated that APAC cells had 78,582 differentially accessible regions compared to AC-NT, the majority (>70%) representing loss of accessibility, whereas AC-sgAP cells showed only 6,587 differentially accessible regions. Transcriptional profiling identified both unique and common significantly differentially expressed genes in APAC and AC-sgAP relative to AC-NT controls. Interestingly, topologically associating domains (TADs) calling revealed that AC-sgAP cells displayed approximately three-fold more differential TADs compared to AC-NT than APAC cells relative to controls. Conclusions Concurrent Arid1a/Pbrm1 loss drives extensive chromatin and transcriptional reprogramming through SWI/SNF redistribution. APAC cells achieving greater transcriptional dysregulation with fewer TAD disruptions might suggest that intra-TAD regulatory changes are critical events in SWI/SNF-mutant cholangiocarcinoma.
