Value of acute neurovascular imaging in patients with suspected transient ischemic attack.

Purpose: Acute neurovascular imaging including MRA and/or CTA are routinely performed in the emergency departments (ED) for patients who present with suspected transient ischemic attacks (TIA). Given the current emphasis on mitigating the rising cost of health care nationally, and promoting high value practice, we sought to determine 1) the value of acute neurovascular imaging in patients presenting to the ED with TIA-like symptoms, and 2) whether these neurovascular studies led to a difference in management strategies.

Method: We retrospectively reviewed 398 ED patients who presented with transient neurological deficits and underwent neurovascular imaging from 2015 to 2018.

Transcranial Magnetic Stimulation and its Imaging Features in Patients With Depression, Post-traumatic Stress Disorder, and Traumatic Brain Injury.

Transcranial magnetic stimulation (TMS) is a type of noninvasive neurostimulation used increasingly often in clinical medicine. While most studies to date have focused on TMS's ability to treat major depressive disorder, it has shown promise in several other conditions including post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI). As different treatment protocols are often used across studies, the ability to predict patient outcomes and evaluate immediate and long-term changes using imaging becomes increasingly important.

Use of Magnetic Resonance Imaging for Orthopedic Trauma and Infection in the Emergency Department.

Conditions affecting the musculoskeletal system constitute a significant portion of medical emergencies in the United States, with traumatic injury and infection being two of the most common etiologies. Although physical examination and plain radiographs are often sufficient to guide diagnosis and treatment, there are myriad traumatic and infectious pathologies that are commonly missed or simply not detectable on plain radiographs. Advanced imaging is subsequently warranted for additional workup.

MRI findings of chronic distal tendon biceps reconstruction and associated post-operative findings.

Rupture of the distal biceps tendon is becoming increasingly diagnosed due to an active aging population and an increase in diagnostic imaging opportunities. While physical exam may help in diagnosis, magnetic resonance imaging (MRI) is particularly useful in evaluating chronic rupture. Although partial tears can be managed conservatively, the gold standard treatment for a chronic distal biceps tear is anatomic reinsertion with additional use of an allograft or autograft.

Which vendor is most cited in the hepatic imaging literature?

Purpose: When deciding among imaging equipment vendors, one may use a vendor's prevalence in peer-reviewed publications as a measure of their research and development. We sought to determine which vendors, countries, and journals were dominant in hepatic imaging literature of 2018 with respect to magnetic resonance (MR), computed tomography (CT), and ultrasound (US).

Methods: We recorded and analyzed the modality (MR, CT, US), journal, vendor, and authors' country for all original hepatic imaging articles published in 2018 in 29 imaging journals.

Vascular imaging in the initial evaluation of embolic stroke source.

Purpose: During acute ischemic stroke evaluations, neurovascular imaging is commonly performed to localize the source of a thromboembolus and to identify vascular stenoses. In this study, we aimed to analyze 1) the usefulness of intracranial and/or cervical CTA and MRA and carotid doppler ultrasound (DUS) for identifying the stroke source and 2) the incidence of vascular stenoses across stroke etiologies.

Methods: We retrospectively reviewed intracranial and/or cervical CTA, DUS and MRA studies to identify the source of the acute stroke by Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria for 200 consecutive patients admitted with a stroke to our tertiary hospital.

Clinical Evaluation of an Individualized Risk Prediction Tool for Men on Active Surveillance for Prostate Cancer.

Objective: To determine whether providing individualized predictions of health outcomes to men on active surveillance (AS) alleviates cancer-related anxiety and improves risk understanding.

Materials And Methods: We consecutively recruited men from our large, institutional AS program before (n = 36) and after (n = 31) implementation of a risk prediction tool. Men in both groups were surveyed before and after their regular visits to assess their perceived cancer control, biopsy-specific anxiety, and burden from cancer-related information.

A scoping review of patient-sharing network studies using administrative data.

There is a robust literature examining social networks and health, which draws on the network traditions in sociology and statistics. However, the application of social network approaches to understand the organization of health care is less well understood. The objective of this work was to examine approaches to conceptualizing, measuring, and analyzing provider patient-sharing networks.

Opportunities for Targeted Education: Critical Neuroradiologic Findings Missed or Misinterpreted by Residents and Fellows.

Objective: We reviewed neuroradiology cases in which a resident or fellow missed a significant finding, to identify potential areas of deficiency that could be strengthened through targeted education.

Materials And Methods: Included in the study were all neuroradiology reports from 2011 through 2013 that were marked with an electronic flag to indicate a significant modification between the preliminary and final versions. The reports were examined to determine whether a critical finding (CF) or a non-CF was missed, with the use of a hospital-approved list of 17 neuroradiology CFs.

Hemoglobin regulates the migration of glioma cells along poly(ε-caprolactone)-aligned nanofibers.

Aligned fibers have been shown to facilitate cell migration in the direction of fiber alignment while oxygen (O2 )-carrying solutions improve the metabolism of cells in hypoxic culture. Therefore, U251 aggregate migration on poly(ε-caprolactone) (PCL)-aligned fibers was studied in cell culture media supplemented with the O2 storage and transport protein hemoglobin (Hb) obtained from bovine, earthworm and human sources at concentrations ranging from 0 to 5 g/L within a cell culture incubator exposed to O2 tensions ranging from 1 to 19% O2 . Individual cell migration was quantified using a wound healing assay.
