Three-Dimensional Reconstruction of Galleries Using CT Scans.

As a vector of pine wood nematode disease, is wood-boring, cryptic, and extremely difficult to control-features that have made them a disastrous problem. In this study, we present a method of scanning the galleries of using CT (computed tomography) technology to obtain their systematic structure via 3D (three-dimensional) reconstruction, so as to clarify the gallery types and their structural parameters. TLC (thin-layer chromatography) scanning on wood segments damaged by was performed using a 128-row spiral CT GE Revolution EVO to obtain 64-layer CT scanned images.

Breast Implant-Associated Anaplastic Large-Cell Lymphoma in Brazil: What Are We Missing?

Background: Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) has been diagnosed in more than 1000 patients in more than 30 countries, although only a few cases have been reported in Latin America and the Caribbean to date. As the second-largest global market for breast implants with a predominance of textured-surface implants, Brazil is a major global market for cosmetic augmentations, making it unlikely that cases of BIA-ALCL are actually scarce.

Methods: A local and voluntary registry of patients with BIA-ALCL was initiated in 2018.

TBX3 activating PVT1 accelerates proliferation, migration, and invasion by modulating the miR-30a/LOX axis in anaplastic thyroid carcinoma.

Introduction: Anaplastic thyroid carcinoma (ATC) is a nearly chemo-resistant malignancy with high invasion and mortality. Long non-coding RNAs (lncRNAs) have been demonstrated to be dysregulated and play a crucial role in the development and process of ATC. The present study aimed to explore the mechanism of PVT1 dysregulation in ATC.

Maintenance of Certification in Radiology: Eliciting Radiologist Preferences Using a Discrete Choice Experiment.

Objective: To quantitatively assess radiologists' preferences for Maintenance of Certification (MOC) and Continuing Certification (CC) using a survey of attitudes and perceptions.

Methods: A questionnaire that assessed attitudes and perceptions and included a discrete choice or trade-off task was developed by ACR staff in conjunction with an independent market research agency and the Survey Subcommittee of the ACR Task Force on Certification in Radiology. The trade-off exercise was integrated into this methodology to better understand the underlying utilities or preferences of the components of MOC-CC among respondents and to better enable specific recommendations on how to optimize the current program.

Objective: To describe a particular type of adverse effect that, unlike the erythematous, indurated, and painful nodules described in the literature as "angry red bumps," is characterized by noninflammatory, stony-like nodules that appear in sites previously treated with HA.

Depatuxizumab mafodotin in EGFR-amplified newly diagnosed glioblastoma: A phase III randomized clinical trial.

Background: Approximately 50% of newly diagnosed glioblastomas (GBMs) harbor epidermal growth factor receptor gene amplification (EGFR-amp). Preclinical and early-phase clinical data suggested efficacy of depatuxizumab mafodotin (depatux-m), an antibody-drug conjugate comprised of a monoclonal antibody that binds activated EGFR (overexpressed wild-type and EGFRvIII-mutant) linked to a microtubule-inhibitor toxin in EGFR-amp GBMs.

Methods: In this phase III trial, adults with centrally confirmed, EGFR-amp newly diagnosed GBM were randomized 1:1 to radiotherapy, temozolomide, and depatux-m/placebo.

Study protocol for a hybrid type 1 effectiveness-implementation trial testing virtual tobacco treatment in oncology practices [Smokefree Support Study 2.0].

Background: Persistent smoking among patients diagnosed with cancer is associated with adverse clinical outcomes, yet an evidence-based tobacco use intervention has not been well-integrated into cancer care in community oncology settings. This paper describes the protocol of a nation-wide clinical trial conducted by the ECOG-ACRIN National Cancer Institute (NCI) Community Oncology Research Program (NCORP) Research Base to assess the effectiveness of a virtual tobacco treatment intervention and the process of implementing tobacco treatment in NCORP community oncology settings.

Methods/design: This two-arm, multisite (n: 49 NCORP sites) hybrid type 1 effectiveness-implementation randomized controlled trial compares the effectiveness of a Virtual Intervention Treatment (VIT) versus an Enhanced Usual Control (EUC) among English and Spanish speaking patients recently diagnosed with cancer, reporting current smoking and receiving care at a participating NCORP Community or Minority/Underserved Site.

Advancing Research on Medical Image Perception by Strengthening Multidisciplinary Collaboration.

Medical image interpretation is central to detecting, diagnosing, and staging cancer and many other disorders. At a time when medical imaging is being transformed by digital technologies and artificial intelligence, understanding the basic perceptual and cognitive processes underlying medical image interpretation is vital for increasing diagnosticians' accuracy and performance, improving patient outcomes, and reducing diagnostician burnout. Medical image perception remains substantially understudied.
