Diagnostic Accuracy of Shear Wave Elastography in Predicting Malignant Origins of Pleural Effusions in Emergency Departments.

: Ultrasound is a valuable diagnostic tool in the diagnostic work-up of dyspnea and can identify even small pleural effusions. The incorporation of shear wave elastography (SWE) represents a possible tool in stratifying pleural effusions by the risk of underlying malignancy. No previous studies on ultrasound with the incorporation of SWE have been conducted in an emergency department (ED), where such stratification might have a clinical impact by hastening referrals for the diagnostic work-up of underlying malignancy.

Intratracheal instillation for the testing of pulmonary toxicity in mice-Effects of instillation devices and feed type on inflammation.

Background: Inhalation exposure is the gold standard when assessing pulmonary toxicity. However, it typically requires substantial amounts of test material. Intratracheal instillation is an alternative administration technique, where the test substance is suspended in a liquid vehicle and deposited into the lung via the trachea.

Three-dimensional spatial localization and volume estimation of prostate tumors using F-PSMA-1007 PET/CT versus multiparametric MRI.

Purpose: Fluorine-18 prostate-specific membrane antigen-1007 positron emission tomography/computed tomography (F-PSMA-1007 PET/CT) has been shown to be superior to multiparametric magnetic resonance imaging (MRI) for the locoregional staging of intermediate-risk and high-risk prostate tumors. This study aims to evaluate whether it is also superior in estimating tumor parameters, such as three-dimensional spatial localization and volume.

Methods: 134 participants underwent F-PSMA-1007 PET/CT and MRI prior to radical prostatectomy as part of the validating paired-cohort Next Generation Trial (NCT05141760).

Preprocessing choices for P3 analyses with mobile EEG: A systematic literature review and interactive exploration.

Preprocessing is necessary to extract meaningful results from electroencephalography (EEG) data. With many possible preprocessing choices, their impact on outcomes is fundamental. While previous studies have explored the effects of preprocessing on stationary EEG data, this research delves into mobile EEG, where complex processing is necessary to address motion artifacts.

Biokinetics of carbon black, multi-walled carbon nanotubes, cerium oxide, silica, and titanium dioxide nanoparticles after inhalation: a review.

Understanding the biokinetics of nanoparticles will support the identification of target organs for toxicological endpoints. We investigated the biokinetics of poorly soluble nanomaterials carbon black, multi-walled carbon nanotubes (MWCNT), cerium oxide (CeO), titanium dioxide (TiO), crystalline silica (SiO) in inhalation studies in rodents (the soluble amorphous silica was also included). By reviewing research papers on the inhalation of these substances, we collected physico-chemical data and elemental distribution to organs, urine, and feces.
