CEUS LI-RADS: a pictorial review

2020

AbstractContrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic tool in the imaging work-up of cirrhotic patients at risk for developing hepatocellular carcinoma (HCC). In particular, CEUS Liver Imaging Reporting and Data System (LI-RADS) provides standardized terminology, interpretation, and reporting for the diagnosis of HCC. The aim of this pictorial essay is to illustrate CEUS features of nodules discovered at US in cirrhotic liver according to LI-RADS categorization.

Diagnostische Aussagekraft von Sonographie und Computertomographie bei Lebermetastasen

1988

The diagnostic accuracy of sonography and computed tomography for detecting liver metastases was analysed in 526 patients with tumors and the findings were compared with those at laparotomy and at post mortem. The surgical protocols were analysed in respect of the primary tumour, the frequency of metastases and the number, localisation and size of metastases. A comparison of sonography and CT showed a higher sensitivity for CT (57.1%) compared with sonography (52.3%) although specificity was slightly higher for sonography. Liver metastases greater than 15 mm were detected by sonography (80.5%) and CT (92%), with much higher sensitivity. CT also proved superior, since the results depended le…

A new tool for sepsis screening in the Emergency Department

2021

Abstract Objectives In this study, we developed and evaluated the diagnostic accuracy of the Sepsis Index for early sepsis screening in the Emergency Department (ED). Methods Sepsis Index is based on the combination of monocyte distribution width (MDW) and mean monocyte volume (MMV). Sepsis Index≥1 was selected to define sepsis. We tested its diagnostic accuracy in an ED population stratified in four groups: controls, Systemic Inflammatory Response Syndrome (SIRS), infection, and sepsis, according to Sepsis-2 criteria. Results Patients with sepsis displayed higher median Sepsis Index value than patients without sepsis. At the receiver operating characterictis (ROC) curve analysis for the pr…

P1296 : Blocking NMDA receptors prolongs survival in rats with acute liver failure by dual protective mechanisms in kidney and brain

2015

were 1094.67±239.37mIU/ml. The difference in values between these groups was statistically significant (p = 0.004). There was a statistically significant difference in total leucocyte count, serum creatinine, INR and cleaved CK18 M30 levels among those that survived vs expired. Multivariate analysis found that all these independently predict mortality. A receiver operating characteristic curve was drawn for the new score. The score found was compared with the King’s College criteria and the MELD score, the new scoring system was found to have higher sensitivity and specificity for mortality compared with other standard prognostic markers in ALF, and has a better diagnostic accuracy (Table 1…

Country of residence, gender equality and victim blaming attitudes about partner violence: a multilevel analysis in EU

2017

Background: Intimate partner violence against women (IPVAW) is a global and preventable public health problem. Public attitudes, such as victim-blaming, are important for our understanding of differences in the occurrence of IPVAW, as they contribute to its justification. In this paper, we focus on victim-blaming attitudes regarding IPVAW within the EU and we apply multilevel analyses to identify contextual determinants of victim-blaming attitudes. We investigate both the general contextual effect of the country and the specific association between country level of gender equality and individual victim-blaming attitudes, as well as to what extend a possible general contextual effect was exp…

Accuracy of pre-hospital triage tools for major trauma: a systematic review with meta-analysis and net clinical benefit

2021

Abstract Background We conducted a systematic review to evaluate and compare the accuracy of pre-hospital triage tools for major trauma in the context of the development of the Italian National Institute of Health guidelines on major trauma integrated management. Methods PubMed, Embase, and CENTRAL were searched up to November 2019 for studies investigating pre-hospital triage tools. The ROC (receiver operating characteristics) curve and net clinical benefit for all selected triage tools were performed. Quality assessment was performed using the Quality Assessment of Diagnostic Accuracy Studies–2. Certainty of the evidence was judged with the Grading of Recommendations Assessment, Developme…

The value of high resolution CT in the diagnosis of meniscal lesions of the knee

1991

We report on 50 patients who had meniscal pathology and were given computed tomographic (CT) scans. Our diagnostic accuracy was approximately 92%. We believe that CT is a good method of screening these patients prior to using a much more expensive method, such as magnetic resonance imaging or diagnostic arthroscopy.

Contrast-enhanced ultrasound of hepatocellular carcinoma: where do we stand?

2019

Contrast-enhanced ultrasound (CEUS) represents a significant breakthrough in ultrasonography (US), and it is being increasingly used for the evaluation of focal liver lesions (FLLs). CEUS is unique in that it allows non-invasively assessment of liver perfusion in real time throughout the vascular phase, which has led to dramatic improvements in the diagnostic accuracy of US in the detection and characterization of FLLs, the choice of therapeutic procedures, and the evaluation of response. Currently, CEUS is included as a part of the suggested diagnostic work-up of FLLs, including in cirrhotic patients with hepatocellular carcinoma, resulting in better patient management and cost-effective d…

Comparison between logbook-reported and objectively-assessed physical activity and sedentary time in breast cancer patients: an agreement study

2017

BACKGROUND: Increasing physical activity (PA) and decreasing sedentary time (ST) have important health effects among breast cancer patients, a growing population group. PA and sedentary behaviors are complex multi-dimensional behaviors and are challenging to monitor accurately. To date few studies have compared self-reports and objective measurement in assessing PA and ST in women undergoing breast cancer treatments. The aim of the present study was to compare self-reports and objective measures for assessing daily time spent in moderate-intensity physical activity (MPA), vigorous-intensity physical activity (VPA) and ST in women undergoing breast cancer treatments. METHODS: Baseline data f…
