Design and Depiction of an Novel Bacmid AcBac-Syn According to a Produced Baculovirus Genome.
Purpose Tumor-infiltrating lymphocytes (TILs) and their spatial characterizations on whole-slide images (WSIs) of histopathology sections have become crucial in diagnosis, prognosis, and treatment response prediction for different cancers. However, fully automatic assessment of TILs on WSIs currently remains a great challenge because of the heterogeneity and large size of WSIs. We present an automatic pipeline based on a cascade-training U-net to generate high-resolution TIL maps on WSIs. Methods We present global cell-level TIL maps and 43 quantitative TIL spatial image features for 1,000 WSIs of The Cancer Genome Atlas patients with breast cancer. For more specific analysis, all the patients were divided into three subtypes, namely, estrogen receptor (ER)-positive, ER-negative, and triple-negative groups. The associations between TIL scores and gene expression and somatic mutation were examined separately in three breast cancer subtypes. Both univariate and multivariate survival analyses were performed on 43 TIL image features to examine the prognostic value of TIL spatial patterns in different breast cancer subtypes. Results The TIL score was in strong association with immune response pathway and genes (eg, programmed death-1 and CLTA4). Different breast cancer subtypes showed TIL score in association with mutations from different genes suggesting that different genetic alterations may lead to similar phenotypes. Spatial TIL features that represent density and distribution of TIL clusters were important indicators of the patient outcomes. Conclusion Our pipeline can facilitate computational pathology-based discovery in cancer immunology and research on immunotherapy. Our analysis results are available for the research community to generate new hypotheses and insights on breast cancer immunology and development.Purpose Institutional efforts toward the democratization of cloud-scale data and analysis methods for cancer genomics are proceeding rapidly. CPT-11 As part of this effort, we bridge two major bioinformatic initiatives the Global Alliance for Genomics and Health (GA4GH) and Bioconductor. Methods We describe in detail a use case in pancancer transcriptomics conducted by blending implementations of the GA4GH Workflow Execution Services and Tool Registry Service concepts with the Bioconductor curatedTCGAData and BiocOncoTK packages. Results We carried out the analysis with a formally archived workflow and container at dockstore.org and a workspace and notebook at app.terra.bio. The analysis identified relationships between microsatellite instability and biomarkers of immune dysregulation at a finer level of granularity than previously reported. Our use of standard approaches to containerization and workflow programming allows this analysis to be replicated and extended. Conclusion Experimental use of dockstore.org and app.terra.bio in concert with Bioconductor enabled novel statistical analysis of large genomic projects without the need for local supercomputing resources but involved challenges related to container design, script archiving, and unit testing. Best practices and cost/benefit metrics for the management and analysis of globally federated genomic data and annotation are evolving. The creation and execution of use cases like the one reported here will be helpful in the development and comparison of approaches to federated data/analysis systems in cancer genomics.Recent advances in the understanding of underlying molecular signaling mechanisms of cancer susceptibility and progression have led to an increase in the use of targeted therapies for cancer treatment. Despite improvements in survival with new treatment options in oncology, resistance to therapy is a major obstacle to the long-term effectiveness of targeted agents in metastatic cancer treatment, culminating in insensitivity to treatment and tumor outgrowth. Adaptive resistance can play an important role in primary and upfront resistance to therapy as well as in secondary or acquired resistance. By focusing on colorectal and breast tumors, we discuss how therapeutic combinations based on specific drivers of tumor biology can be used to overcome resistance. We present how monitoring tumor dynamics over time may allow early adaptation of treatment. Breast cancer is the most common malignancy in women worldwide, and the majority of these cancers are sensitive to endocrine therapy (ET) blocking the production of or response to estrogen. However, primary and acquired resistance limits efficacy. Recent combinations of agents targeted to pathways that drive tumor growth resistance with ET have resulted in remarkable improvements in disease response and control, improving survival in some settings. In this review, we summarize adaptive resistance mechanisms, approaches to combination strategies, and dynamic tumor monitoring to improve efficacy and overcome resistance. We provide examples of combination therapy to enhance the efficacy of targeted therapies in breast and colorectal tumors.Changes in the health insurance coverage landscape in the United States during the past decade have important implications for receipt and affordability of cancer care. In this paper, we summarize evidence for the association between health insurance coverage and cancer prevention and treatment. We then discuss ongoing changes in health care coverage, including implementation of provisions of the Affordable Care Act, increasing prevalence of high-deductible health insurance plans, and factors that affect health care delivery, with a focus on vertical integration of hospitals and providers. We summarize the evidence for the effects of the changes in health coverage on care and discuss areas for future research with the goal of informing efforts to improve cancer care delivery and outcomes in the United States.The rapid expansion of modern cancer immunotherapeutics has led to a dramatic improvement in patient survival and sustained remission for otherwise refractory malignancies. However, a significant limitation behind these current treatment modalities is an irregularity in clinical response, which is especially pronounced among checkpoint inhibition. This unpredictability leads to significant side effects, financial costs, and health care burden, with unsatisfactory clinical benefit in the majority of treated patients. Additionally, although ongoing studies and trials investigate the use of multiple biomarkers predictive of patient response or harm, none of these are comprehensive in predicting potential benefit. This unmet need for validated biomarkers is largely secondary to a prohibitive complexity within tumor parenchyma and microenvironment, dynamic clonal and proteomic changes to therapy, heterogenous host immune defects, and varied standardization among sample preparation and reporting. Herein, we discuss current advantages of predictive biomarkers, as well as limitations in their clinical use and application. We also review future directions, ideal characteristics, and trial design needed for proper precision immuno-oncology and biomarker development.Background Graft bridging is used in massive rotator cuff tear (MRCT); however, the integration of graft-tendon and graft-bone is still a challenge. Hypothesis A co-electrospinning nanoscaffold of polycaprolactone (PCL) with an "enthesis-mimicking" (EM) structure could bridge MRCT, facilitate tendon regeneration, and improve graft-bone healing. Study design Controlled laboratory study. Methods First, we analyzed the cytocompatibility of the electrospinning nanoscaffolds, including aligned PCL (aPCL), nonaligned PCL (nPCL), aPCL-collagen I, nPCL-collagen II, and nPCL-nanohydroxyapatite (nHA). Second, for the EM condition, nPCL-collagen II and nPCL-nHA were electrospun layer by layer at one end of the aPCL-collagen I; for the control condition, the nPCL was electrospun on the aPCL. In 40 mature male rats, resection of both the supraspinatus and infraspinatus tendons was performed to create MRCT, and the animals were divided randomly into EM and control groups. In both groups, one end of the layered structure wantrol group at 8 weeks. Conclusion The co-electrospinning nanoscaffold of aPCL-collagen I could be used as a bridging graft to improve early graft-tendon healing for MRCT in a rat model and enhance early enthesis reconstruction in combination with a multilayered structure of nPCL-collagen II and nPCL-nHA. Clinical relevance We constructed a graft to bridge MRCT, enhance graft-tendon healing and graft-bone healing, and reconstruct the enthesis structure.Objective To define critical elements that contribute to successful parathyroidectomy based on a high-volume single-surgeon experience and explore learning curve characteristics. Study design Systematic analysis of prospectively maintained quality assurance database. Setting Academic tertiary care endocrine surgery practice. Subjects and methods In total, 4737 consecutive patients who underwent thyroid or parathyroid surgery from 2004 to 2020 were identified. Demographic data acquisition was undertaken on a subset of these patients who had initial surgery for primary hyperparathyroidism during the academic years 2005 to 2018. Patients with renal or syndromic hyperparathyroidism and those undergoing reoperative surgery were excluded. link2 Results From 1710 patients who underwent parathyroid surgery, 1082 met inclusion criteria in order to focus on a homogeneous data set. These patients had a mean age of 60.1 ± 12.5 years and 76.4% were female. The overall cure rate was 98.3%, reflecting a success rate that increased from 95.5% during the first 200 cases to 99.7% over the final 300 cases. The complication rate was 1.7%. Over 2 decades, the patient phenotype evolved toward milder disease and smaller adenomas. A learning curve of 200 cases was required to become a proficient parathyroid surgeon; to achieve exceptional results required several hundred additional cases. Parathyroid surgery represents a higher proportion of an endocrine surgery practice than previously (54.0% in 2019 compared with 25.5% in 2004). Conclusion A focused practice dedicated to endocrine surgery yields surgical volumes exceeding 500 cases annually. There has been a steady shift toward parathyroid surgery. A lengthy learning curve can be shortened by pursuit of several specific strategies that are outlined in detail.Objective As awareness of educator stress and burnout is at the forefront of issues faced in the education system, programs are being implemented to focus on the well-being and betterment of educators. Mindfulness is one such practice that has been found to increase wellness and, in many cases, decrease negative outcomes. In this study, the effects of a Mindfulness-Based Stress Reduction Program were measured in grade-school (K-12) educators. Design A longitudinal noncontrolled trial of educators who completed baseline and short- and long-term postintervention surveys. Location Miami-Dade County. link3 Subjects Two hundred thirty-six educators who worked in K-12 public and private schools. Intervention An 8-week Mindfulness-Based Stress Reduction Program. Outcome measures Five Facet Mindfulness Questionnaire, Self-Compassion Scale, Maslach Burnout Inventory-Educators, Patient-Reported Outcome Measurement Information System (PROMIS-29) for measuring physical and mental health functionality. Results The multiple linear regression analysis of the short-term cohort data yielded statistically significant improvements in mindfulness, self-compassion, and personal accomplishment and decreases in isolation, anxiety, fatigue, and emotional exhaustion.
