Detection of pulmonary embolism using repeated MRI acquisitions without respiratory gating: a preliminary study.

CONCLUSION: Our unenhanced MRI protocol shows a high sensitivity and specificity for PE, but further studies are required before considering it as a safe diagnostic test. PMID: 27273375 [PubMed - as supplied by publisher]

AbstractABO blood group has been associated with various disease phenotypes. However, ABO blood group to influence patients in risk of venous thromboembolic events (VTEs) and arterial thromboembolic events (ATEs) remains controversial after evaluation in several reports. To fully assess effects of ABO blood group on VTEs and ATEs, we conducted a cross-sectional study and investigated the interaction between blood group and age, and between blood group and sex on the prevalence of VTEs and ATEs. In addition, the effect of blood group on ATEs in patients with atrial fibrillation (AF) was observed. Detailed information of 783...

Authors: Zou J, Li C, Chen Y, Chen R, Xue T, Xie X, Zhang L, Ren Z Abstract Spontaneous rupture is one of the complications of hepatocellular carcinoma (HCC) associated with a high mortality rate. Transcatheter arterial chemoembolization (TACE) has been widely used in patients with ruptured liver tumors. The aim of the present study was to evaluate the benefits and safety of conventional TACE and the disease prognosis following TACE and surgery with regard to the progression of spontaneously ruptured HCC. The clinical data of 70 patients diagnosed with spontaneous rupture of HCC were retrospectively reviewed. The m...

A 64-year-old woman with a history of cirrhosis and progressive difficulty breathing underwent pulmonary ventilation/perfusion SPECT to evaluate possible pulmonary embolism. The images demonstrated multiple mismatched ventilation/perfusion defects in both lungs, suggesting pulmonary embolism. However, there was also 99mTc-MAA radioactivity in the brain and bilateral kidney, with a right-to-left shunting rate of 8.8%. In addition, CT pulmonary angiography did not demonstrate embolus. The findings indicated that perfusion defects were caused by hepatopulmonary syndrome.

Authors: Peterson EA, Lee AYY Abstract Malignancy is associated with a high risk of venous thromboembolism (VTE), and treatment with anticoagulant therapy is associated with a high risk of bleeding. Thus, accurate and timely VTE diagnosis in cancer patients is essential for identifying individuals who would benefit from anticoagulant therapy and for avoiding unnecessary treatment that can cause anticoagulant-related bleeding. The approach to the diagnosis of VTE in non-cancer patients involves a stepwise process beginning with an assessment of the pretest probability (PTP) of VTE using a validated clinical predicti...

Authors: Zhang Y, Ma L, Fu Q, Zhao T, Yan RY, Su X Abstract Thrombolytic treatment is recommended for patients with high-risk pulmonary embolism. The present study compared thrombolytic therapy with urokinase and reteplase. A total of 37 patients presenting with acute high-risk pulmonary embolism at the Intensive Care Unit of Weinan Central Hospital of Shaanxi Province (Weinan, China) between June 2013 and January 2017 were retrospectively analyzed. According to their treatment, these subjects were assigned to the reteplase group (n=16) or the urokinase group (n=21). Systolic blood pressure (SBP), heart rate (HR) a...

AbstractPurposeThe purpose of this study is to determine the rates of CT pulmonary angiography (CTPA) interpreted as limited and severely limited in pregnant patients suspected for pulmonary embolism (PE), and to evaluate factors that influence these rates.MethodsThis is a retrospective study with CTPA for evaluation of PE in pregnancy across a large health system from 2006 to 2017. CTPA was classified as limited from the radiology report with a subset of those studies classified as severely limited. Bivariate and multivariate analysis was performed for limited and severely limited rates with maternal age and patient size ...

ABSTRACT Aneurysmal subarachnoid hemorrhage is a condition with a considerable incidence variation worldwide. In Brazil, the exact epidemiology of aneurysmal SAH is unknown. The most common presenting symptom is headache, usually described as the worst headache ever felt. Head computed tomography, when performed within six hours of the ictus, has a sensitivity of nearly 100%. It is important to classify the hemorrhage based on clinical and imaging features as a way to standardize communication. Classification also has prognostic value. In order to prevent rebleeding, there still is controversy regarding the ideal blood pre...

By YOLONDA Y. WILSON, PhD Last week a nurse posted a video of herself on Twitter mocking patients with the caption “We know when y’all are faking” followed by laughing emojis. Twitter responded with the hashtag #patientsarenotfaking, created by Imani Barbarin, and a slew of testimonials of negligent medical care. While the nurse’s video was not explicitly racialized, plenty in the black community felt a particular sting: there is clear evidence that this attitude contributes to the problem of black patients receiving substandard care, and that negative behavioral traits&n...
