Enhancing Clinic Efficiency: A Quality Improvement Initiative For Postoperative Patient Care In An Outpatient Orthopedic Physician Practice Setting, D Stepan, T Jp Greffly, R M. Williams

Clinical Practice in Athletic Training

Introduction: Following orthopedic surgery, patient post-operative (post-op) visits are deemed global surgical observations where day 00 to day 90 are appointments that cannot be billed. Patients are typically seen 3 times during this global period. Thus, the outpatient clinic needs to have non-billable time slots each day for these patients. The current scheduling model double books patients every 15 minutes, with the physician being the primary provider seeing patients for post-op visits. Therefore, the clinic has demonstrated inefficiencies with scheduling these patients while having sufficient appointments available for billable patients. This quality improvement initiative aimed to decrease post-op patient visits …

Multiple myeloma is a clonal plasma cell (PC) dyscrasia that arises from precursors and has been studied utilizing approaches focused on CD138+ cells. By combining single-cell RNA sequencing (scRNA-seq) with scB-cell receptor sequencing (scBCR-seq), we differentiate monoclonal/neoplastic from polyclonal/normal PCs and find more dysregulated genes, especially in precursor patients, than we would have by analyzing bulk PCs. To determine whether this approach can identify oncogenes that contribute to disease pathobiology, mitotic arrest deficient-2 like-1 (MAD2L1) and S-adenosylmethionine synthase isoform type-2 (MAT2A) are validated as targets with drug-like molecules that suppress myeloma growth in preclinical models. Moreover, functional studies show a …

Approximately 30% of patients with chronic myelomonocytic leukemia (CMML) undergo transformation to a chemo-refractory blastic phase (BP-CMML). Seeking novel therapeutic approaches, we profiled blast transcriptomes from 42 BP-CMMLs, observing extensive transcriptional heterogeneity and poor alignment to current acute myeloid leukemia (AML) classifications. BP-CMMLs display distinctive transcriptomic profiles, including enrichment for quiescence and variability in drug response signatures. Integrating clinical, immunophenotype, and transcriptome parameters, Random Forest unsupervised clustering distinguishes immature and mature subtypes characterized by differential expression of transcriptional modules, oncogenes, apoptotic regulators, and patterns of surface marker expression. Subtypes differ in predicted response to AML drugs, validated ex vivo in …

Lynch syndrome (LS), caused by inherited mutations in DNA mismatch repair genes, including MSH2, carries a 60% lifetime risk of developing endometrial cancer (EC). Beyond hypermutability, mechanisms driving LS-associated EC (LS-EC) remain unclear. We investigated MSH2 loss in EC pathogenesis using a mouse model (PR-Cre Msh2LoxP/LoxP, abbreviated Msh2KO), primary cell lines, human tissues, and human EC cells with isogenic MSH2 knockdown. By 8 months, 58% of Msh2KO mice developed endometrial atypical hyperplasia (AH), a precancerous lesion. At 12-16 months, 50% of Msh2KO mice exhibited either AH or ECs with histologic similarities to human LS-ECs. Transcriptomic profiling of EC from Msh2KO …

Background: Cyclin-dependent kinase 4/6 inhibitors (CDK4/6is) in combination with endocrine therapy are the standard treatment for patients with hormone receptor-positive, HER2-negative metastatic breast cancer (mBC). Despite the efficacy of CDK4/6is, intrinsic resistance occurs in approximately one-third of patients, highlighting the need for reliable predictive biomarkers.

Methods: Single-cell RNA sequencing analyzed metastatic tumors from HR+/HER2- mBC patients pre-CDK4/6i treatment at baseline (BL) and/or at disease progression. BL samples were from CDK4/6i responders (median progression-free survival [mPFS] = 25.5 months), while progressors were categorized as early-progressors (EP, mPFS = 3 months) and late-progressors (LP, mPFS = 11 months).

Adaptive immunity is critical in eliminating tumors, but cancer-intrinsic factors can subvert this function. Melanoma antigen-A4 (MAGE-A4), a cancer-testis antigen, is expressed in solid tumors and correlates with poor survival, but its role in tumorigenesis and antitumor immunity remains unclear. We found that expression of MAGE-A4 was highly associated with the loss of PTEN, a tumor suppressor, in human non–small cell lung cancers (NSCLC). Here, we show that constitutive expression of human MAGE-A4 with Pten loss in mouse airway epithelia results in metastatic adenocarcinoma. Tumors showed distinct enrichment in IgA+ CD138+ CXCR4+ plasma cells (PCs) and increased expression of …
