Clot-targeted magnetic hyperthermia permeabilizes blood clots to make them more susceptible to thrombolysis
CONCLUSIONS: This study demonstrates that clot-targeted MH can enhance the thrombolysis of contracted human blood clots and can be safely applied to enhance the timeframe in which thrombolysis is effective.PMID:35950914 | DOI:10.1111/jth.15846

Hypoxanthine is a pharmacodynamic marker of ischemic brain edema modified by glibenclamide
Cell Rep Med. 2022 Jun 9:100654. doi: 10.1016/j.xcrm.2022.100654. Online ahead of print.ABSTRACTBrain edema after a large stroke causes significant morbidity and mortality. Here, we seek to identify pharmacodynamic markers of edema that are modified by intravenous (i.v.) glibenclamide (glyburide; BIIB093) treatment. Using metabolomic profiling of 399 plasma samples from patients enrolled in the phase 2 Glyburide Advantage in Malignant Edema and Stroke (GAMES)-RP trial, 152 analytes are measured using liquid chromatography-tandem mass spectrometry. Associations with midline shift (MLS) and the matrix metalloproteinase-9 (MM...

Time Efficient Multi-Pulsed Field Gradient (mPFG) MRI Without Concomitant Gradient Field Artifacts
Measuring and mapping nervous tissue microstructure noninvasively is a long sought-after goal in neuroscience. Clinically, several neuropathologies such as cancer and stroke, are associated with changes in tissue microstructure. Diffusion tensor imaging (DTI), which models diffusion anisotropy, is an ideal imaging modality to elucidate these changes. However, DTI provides a mean diffusion tensor averaged over the entire MRI voxel. This has limitations when applied to heterogeneous neural tissue. Although some of these could be overcome by increased spatial resolution, this comes at the cost of reduced signal-to-noise ratio...

Recurrent Strokes as the First Presentation of Occult Pancreatic Cancer; Trousseau Syndrome: A Case Report
We present a case of a 64-year-old female with recurrent ischemic stroke of unknown cause and involving different arterial territories, who was discovered to have metastatic pancreatic cancer. The initial workup with brain imaging revealed multiple acute/subacute ischemic strokes and a negative cardiac assessment. Accordingly, she underwent a whole-body positron emission tomography-computed tomography which revealed a hypermetabolic mass lesion in the pancreaticoduodenal area. Our case indicates that cancer-associated stroke should be seriously evaluated. It demonstrates the critical nature of contemplating hidden cancer i...

Bringing WISDOM to Breast Cancer Care
Dr. Laura Esserman answers the door of her bright yellow Victorian home in San Francisco’s Ashbury neighborhood with a phone at her ear. She’s wrapping up one of several meetings that day with her research team at University of California, San Francisco, where she heads the Carol Franc Buck Breast Care Center. She motions me in and reseats herself at a makeshift home office desk in her living room, sandwiched between a grand piano and set of enormous windows overlooking her front yard’s flower garden. It’s her remote base of operations when she’s not seeing patients or operating at the hospita...

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Thrombotic Thrombocytopenic Purpura Without Schistocytes: Beware of Misdiagnosis
A 43-year-old woman was admitted for acute unusual headache, vertigo, and left upper limb weakness. She had been complaining of asthenia for the past few weeks. Her medical history included uterine cervix cancer treated with conisation and 2 pregnancies without serious complications. No allergy or recent drug introduction was noted. After ruling out current pregnancy, magnetic resonance imaging (MRI) was immediately performed and showed recent ischemic strokes in multiple territories. Doppler ultrasound imaging showed no carotid or vertebral arteries lesion. Electrocardiogram showed no ST elevation or atrial fibrillation, ...

Cerebellar Stroke and Leptomeningeal Carcinomatosis following Cement Leakage into the Vertebral Artery during Cervical Vertebroplasty
This report describes an unusual vertebral artery cement embolization during C3 transpedicular vertebroplasty performed under computed tomography (CT) guidance and fluoroscopy. The Institutional Review Board approved this case report, and the patient ’s consent for publication was obtained. A 54-year-old woman with an invasive lobular breast carcinoma suffered from cervical pain. A CT scan showed spinal osteolytic lesions. A thoracic vertebral biopsy confirmed the diagnosis of breast cancer metastasis.
