A Multidisciplinary Approach to Improve Pain Management and Satisfaction in a Trauma Population.

An adult trauma center identified pain management as a potential area for improvement. Pain management is at the height of discussion in medical centers across the United States. The Hospital Consumer Assessment of Healthcare Provider and System (HCAHPS) scores relating to pain management were consistently low (<5th percentile). This project was designed to use a collaborative and systematic approach to pain management to improve HCAHPS pain management scores. This is an evaluation of a quality improvement project using a before-and-after design with historical control. Using HCAHPS data to evaluate patients' pain management perceptions, an integrative three-pronged approach was developed and implemented: (1) development of a trauma nurse leadership program, (2) collaboration with pain management providers, and (3) modifications made to the trauma admission order set. Trauma nurse leaders educated patients and families regarding pain management goals and expectations utilizing a standardized script. HCAHPS survey data obtained before and after the intervention showed a significant improvement in patient satisfaction. HCAHPS scores on the three pain questions prior to intervention in Quarters 2 and 3 (Q2-3) 2017 had a mean of less than the 5th percentile. After intervention, HCAHPS scores on the three pain questions improved to a mean of more than the 60th percentile on Q4 2018. Implementation of a pain management strategy involving a three-pronged approach of a dedicated trauma nurse leadership program, collaboration with a pain management team, and evaluation and modification of a trauma admission order set was associated with an improvement in communication about pain with the trauma patients and HCAHPS pain satisfaction scores.

Traumatic Hallux Metatarsophalangeal Joint Medial Collateral Ligament Avulsion in a Professional Surfer: Suture Anchor Repair and Suture Tape Augmentation: A Case Report.

CASE: Acute medial collateral ligament (MCL) tears of the great toe metatarsophalangeal joint are rare, leading to sparse literature regarding their management. Suture anchor repair with suture tape augmentation is an effective treatment of thumb ulnar collateral ligament tears, a close analog. This case report presents a 23-year-old professional surfer with an acute hallux MCL avulsion. Management included repair with suture anchor and suture tape augmentation. The patient returned to sport quickly and had no pain or complications at 1-year follow-up. CONCLUSION: In this case of acute MCL tear of the great toe, suture anchor repair with suture tape augmentation facilitated early mobilization, rapid rehabilitation, return to competitive sport, and sustained good outcome. LEVEL OF EVIDENCE: Level V.

Real-world Evidence of Diagnostic Testing and Treatment Patterns in US Patients With Breast Cancer With Implications for Treatment Biomarkers From RNA Sequencing Data.

OBJECTIVE/BACKGROUND: We performed a retrospective analysis of longitudinal real-world data (RWD) from patients with breast cancer to replicate results from clinical studies and demonstrate the feasibility of generating real-world evidence. We also assessed the value of transcriptome profiling as a complementary tool for determining molecular subtypes. METHODS: De-identified, longitudinal data were analyzed after abstraction from records of patients with breast cancer in the United States (US) structured and stored in the Tempus database. Demographics, clinical characteristics, molecular subtype, treatment history, and survival outcomes were assessed according to strict qualitative criteria. RNA sequencing and clinical data were used to predict molecular subtypes and signaling pathway enrichment. RESULTS: The clinical abstraction cohort (n = 4000) mirrored the demographics and clinical characteristics of patients with breast cancer in the US, indicating feasibility for RWE generation. Among patients who were human epidermal growth factor receptor 2-positive (HER2+), 74.2% received anti-HER2 therapy, with ∼70% starting within 3 months of a positive test result. Most non-treated patients were early stage. In this RWD set, 31.7% of patients with HER2+ immunohistochemistry (IHC) had discordant fluorescence in situ hybridization results recorded. Among patients with multiple HER2 IHC results at diagnosis, 18.6% exhibited intra-test discordance. Through development of a whole-transcriptome model to predict IHC receptor status in the molecular sequenced cohort (n = 400), molecular subtypes were resolved for all patients (n = 36) with equivocal HER2 statuses from abstracted test results. Receptor-related signaling pathways were differentially enriched between clinical molecular subtypes. CONCLUSIONS: RWD in the Tempus database mirrors the overall population of patients with breast cancer in the US. These results suggest that real-time, RWD analyses are feasible in a large, highly heterogeneous database. Furthermore, molecular data may aid deficiencies and discrepancies observed from breast cancer RWD.

Female chromosome X mosaicism is age-related and preferentially affects the inactivated X chromosome.

To investigate large structural clonal mosaicism of chromosome X, we analysed the SNP microarray intensity data of 38,303 women from cancer genome-wide association studies (20,878 cases and 17,425 controls) and detected 124 mosaic X events >2 Mb in 97 (0.25%) women. Here we show rates for X-chromosome mosaicism are four times higher than mean autosomal rates; X mosaic events more often include the entire chromosome and participants with X events more likely harbour autosomal mosaic events. X mosaicism frequency increases with age (0.11% in 50-year olds; 0.45% in 75-year olds), as reported for Y and autosomes. Methylation array analyses of 33 women with X mosaicism indicate events preferentially involve the inactive X chromosome. Our results provide further evidence that the sex chromosomes undergo mosaic events more frequently than autosomes, which could have implications for understanding the underlying mechanisms of mosaic events and their possible contribution to risk for chronic diseases.

Adoptive transfer of activated marrow-infiltrating lymphocytes induces measurable antitumor immunity in the bone marrow in multiple myeloma.

Successful adoptive T cell therapy (ACT) requires the ability to activate tumor-specific T cells with the ability to traffic to the tumor site and effectively kill their target as well as persist over time. We hypothesized that ACT using marrow-infiltrating lymphocytes (MILs) in multiple myeloma (MM) could impart greater antitumor immunity in that they were obtained from the tumor microenvironment. We describe the results from the first clinical trial using MILs in MM. Twenty-five patients with either newly diagnosed or relapsed disease had their MILs harvested, activated and expanded, and subsequently infused on the third day after myeloablative therapy. Cells were obtained and adequately expanded in all patients with anti-CD3/CD28 beads plus interleukin-2, and a median of 9.5 × 10(8) MILs were infused. Factors indicative of response to MIL ACT included (i) the presence of measurable myeloma-specific activity of the ex vivo expanded product, (ii) low endogenous bone marrow T cell interferon-γ production at baseline, (iii) a CD8(+) central memory phenotype at baseline, and (iv) the generation and persistence of myeloma-specific immunity in the bone marrow at 1 year after ACT. Achieving at least a 90% reduction in disease burden significantly increased the progression-free survival (25.1 months versus 11.8 months; P = 0.01). This study demonstrates the feasibility and efficacy of MILs as a form of ACT with applicability across many hematologic malignancies and possibly solid tumors infiltrating the bone marrow.

Detectable clonal mosaicism and its relationship to aging and cancer.

In an analysis of 31,717 cancer cases and 26,136 cancer-free controls from 13 genome-wide association studies, we observed large chromosomal abnormalities in a subset of clones in DNA obtained from blood or buccal samples. We observed mosaic abnormalities, either aneuploidy or copy-neutral loss of heterozygosity, of >2 Mb in size in autosomes of 517 individuals (0.89%), with abnormal cell proportions of between 7% and 95%. In cancer-free individuals, frequency increased with age, from 0.23% under 50 years to 1.91% between 75 and 79 years (P = 4.8 × 10(-8)). Mosaic abnormalities were more frequent in individuals with solid tumors (0.97% versus 0.74% in cancer-free individuals; odds ratio (OR) = 1.25; P = 0.016), with stronger association with cases who had DNA collected before diagnosis or treatment (OR = 1.45; P = 0.0005). Detectable mosaicism was also more common in individuals for whom DNA was collected at least 1 year before diagnosis with leukemia compared to cancer-free individuals (OR = 35.4; P = 3.8 × 10(-11)). These findings underscore the time-dependent nature of somatic events in the etiology of cancer and potentially other late-onset diseases.
