Background: Early COVID-19 research suggests a detrimental impact of the initial lockdown on young people's mental health.
Aims: We investigated mental health among university students and young adults after the first UK lockdown and changes in symptoms over 6 months.
Method: In total, 895 university students and 547 young adults not in higher education completed an online survey at T1 (July-September 2020).
Purpose: To determine the diagnostic efficacy of gadolinium-based contrast agents for the detection of recurrent soft-tissue sarcoma compared with non-contrast-enhanced conventional MRI sequences.
Materials And Methods: A retrospective study of patients with soft-tissue sarcomas who were imaged from January 2009 to December 2014 was performed. MRI studies from 69 patients (mean age, 61 years ± 15 [standard deviation], 45 men) with recurrent soft-tissue sarcoma and 63 age-, sex-, and tumor-matched controls with positive findings (nonrecurrence) were presented to six musculoskeletal radiologists at a tertiary cancer center in three image groupings.
A probabilistic forecast is one that assigns a probability (or likelihood) to the occurrence of an event. Radiologists commonly make probabilistic judgments in their reports, even if these predictions are not explicitly expressed as numbers. There are calls for radiologists to commit to their probabilistic predictions in a standardized fashion; however, without a mechanism for feedback, there is no opportunity for improvement.

Our objective was to compare the performance of some of the most commonly used VTEs RAMs in our patient population in the peripartum period.
Study Design: This is a retrospective cohort of women who delivered at our institution in 2015 and 2016.
Study Design: Case report and literature review.
Objective: To describe treatment of a unique case of acute airway obstruction by a large C7 giant cell tumor (GCT) with preoperative denosumab followed by surgical resection, and review the literature on this rare entity.
Summary Of Background Data: Standard treatment for GCTs includes surgical resection or curettage and packing.
Enlargement of kidney tubules is a common feature of multiple cystic kidney diseases in humans and mice. However, while some of these pathologies are characterized by cyst expansion and organ enlargement, in others, progressive interstitial fibrosis and kidney atrophy prevail. The Kif3a knockout mouse is an established non-orthologous mouse model of cystic kidney disease.

Hedgehog (Hh) is an evolutionary conserved signaling pathway that has important functions in kidney morphogenesis and adult organ maintenance. Recent work has shown that Hh signaling is reactivated in the kidney after injury and is an important mediator of progressive fibrosis. Pericytes and fibroblasts have been proposed to be the principal cells that respond to Hh ligands, and pharmacological attenuation of Hh signaling has been considered as a possible treatment for fibrosis, but the effect of Hh inhibition on tubular epithelial cells after kidney injury has not been reported.

For the practice of radiology, the transition to filmless imaging operations has resulted in a fundamental transition to more efficient clinical operations. In addition, the electronic delivery of diagnostic studies to the bedside has had a great impact on the care process throughout the health care enterprise. The radiology information system (RIS) has been at the core of the transition to filmless patient care.

On the basis of miRNA gene expression in gliomas using tissue microarrays, in situ hybridization, and molecular modeling, miR-124 was identified as a lead candidate for modulating STAT3 signaling, a key pathway mediating immunosuppression in the tumor microenvironment. miR-124 is absent in all grades and pathologic types of gliomas.

Glioblastoma (GB), the most common primary neoplasm of the CNS, remains universally fatal with standard therapies and has a mean overall survival time of only 14.6 months. Even in the most favorable situations most patients do not survive longer than 2 years.

The identity and complete sequence of those events remain unknown. Previous studies relied mainly on cell size changes to identify systematically genes required for the timely completion of START.

Materials And Methods: This is a retrospective review of the clinical history and imaging of 11 patients whose central line migrated from the superior vena cava to the azygos vein. The time course of migration, access route of the catheters, outcome, and depth of placement in the superior vena cava were evaluated.
Melanoma is a common and deadly tumor that upon metastasis to the central nervous system (CNS) has median survival duration of less than 5 months. Activation of the signal transducer and activator of transcription 3 (STAT3) has been identified as a key mediator that drives the fundamental components of melanoma. We hypothesized that WP1066, a novel inhibitor of STAT3 signaling, would enhance the antitumor activity of cyclophosphamide (CTX) against melanoma, including disease within the CNS.

Materials And Methods: This study is HIPAA compliant and informed consent was waived by the institutional review board. An institutional database search was performed over a 1-year period for patients with full- and half-dose MR examinations performed for musculoskeletal oncologic indications.
The absence of user-friendly systems for reporting complications is a major barrier to improving quality assurance (QA) programs in interventional radiology (IR) services. We describe the implementation of a QA application that is completely integrated with the radiology dictation system. We implemented an IR QA process as a module within the electronic medical record and radiologist dictation system applications used at our institution.

Therefore, management of long-term bone health is emerging as an important aspect of comprehensive cancer care. Patients with cancer typically have a number of additional risk factors for osteoporosis that should prompt screening, regardless of patient age or sex.

Weekly averages for number of images per study (IPS) were collected from MSCT and SSHCT scanners from 1-01 to 7-01. Average cycle times (ACT) and number of studies per patient (ANSPP) were analyzed from two MSCT and SSHCT scanners for the period of 1-1-00 to 4-1-01, and 4-1-01 to 8-1-01.
