Radiographic horizontal gaze deviation in the setting of acute PICA territory ischemia: A potential mimic of large vessel occlusion.

Purpose: Horizontal gaze deviation (HGD) is a predictor of acute large vessel occlusion (LVO) and helps to expedite the triage of patients to CTA and endovascular-capable sites. Patients with acute cerebellar ischemia, particularly involving the PICA territory, can also exhibit HGD.

Materials And Methods: We reviewed 2260 CTA stroke assessment cases between January 2016 and May 2020.

Comparison of hydrochloric acid infusion radiofrequency ablation with microwave ablation in an ex vivo liver model.

To compare sizes and shapes of ablation zones resulting from hydrochloric acid infusion radiofrequency ablation (HRFA) and microwave ablation (MWA), using normal saline infusion radiofrequency ablation (NSRFA) as a control, at a variety of matched power settings and ablation durations, in an bovine liver model. A total of 90 ablation procedures were performed, using each of three modalities: NSRFA, HRFA, and MWA. For each modality, five ablation procedures were performed for each combination of power (80 W, 100 W, or 120 W) and duration (5, 10, 20, 30, 45, or 60 min).

Hypovascular pancreas head adenocarcinoma: CT texture analysis for assessment of resection margin status and high-risk features.

Objectives: To determine if CT texture analysis features are associated with hypovascular pancreas head adenocarcinoma (PHA) postoperative margin status, nodal status, grade, lymphovascular invasion (LVI), and perineural invasion (PNI).

Methods: This Research Ethics Board-approved retrospective cohort study included 131 consecutive patients with resected PHA. Tumors were segmented on preoperative contrast-enhanced CT.

Degree of Conjugate Gaze Deviation on CT Predicts Proximal Vessel Occlusion and May Expedite Endovascular Therapy.

Purpose: Recent trials have demonstrated superior outcomes with combination IV-tPA and endovascular therapy (EVT) within 6 hours of symptom onset in patients with proximal vessel occlusion (ICA, M1, or proximal M1/M2) compared to IV-tPA alone. The current standard of diagnosis for consideration of EVT is CT angiogram (CTA). Unfortunately, not all hospitals are equipped with CTA, and the decision to transfer to tertiary centers is often based on nonenhanced CT.

Magnetic Resonance Elastography to Assess Fibrosis in Kidney Allografts.

Background And Objectives: Fibrosis is a major cause of kidney allograft injury. Currently, the only means of assessing allograft fibrosis is by biopsy, an invasive procedure that samples <1% of the kidney. We examined whether magnetic resonance elastography, an imaging-based measure of organ stiffness, could noninvasively estimate allograft fibrosis and predict progression of allograft dysfunction.

Influence of transport conditions and pre-slaughter water shower spray during summer on protein characteristics and water distribution of broiler breast meat.

This study investigated the effects of pre-slaughter transport during summer and subsequent water shower spray on broiler meat quality and protein characteristics. Arbor Acres broiler chickens (n = 126, 42 days old, mixed sex, 2.5-3 kg) were randomly categorized into three treatments: (i) control group without transport (C); (ii) 30 min transport (T); and (iii) 30 min transport followed by 10 min water shower spray and 20 min lairage (T/W).

Impact of cytogenetics in patients with relapsed or refractory multiple myeloma treated with bortezomib: Adverse effect of 1q21 gains.

We investigated the influence of genetic risk factors on the clinical response to bortezomib in 85 relapsed/refractory multiple myeloma (MM) patients. Interphase cytoplasmic fluorescence in situ hybridization (cIg-FISH) detected del(13q), del(17p), del(1p21), t(4;14), and 1q21 gain in 38%, 22%, 26%, 18% and 39% of evaluable cases. Forty-nine patients (49%) responded to bortezomib with median progression free (PFS) and overall survivals (OS) of 5.
