Comparison of Y SIRT predicted and delivered absorbed doses using a PSF conversion method.

Phys Med 2021 Jul 30;89:1-10. Epub 2021 Jul 30.

Joint Department of Physics, Royal Marsden NHSFT, Sutton, United Kingdom; The Institute of Cancer Research, London, United Kingdom.

Purpose: The aims of this study were to develop and apply a method to correct for the differences in partial volume effects of pre-therapy Technetium-99 m (Tc)-MAA SPECT and post-therapy Yttrium-90 (Y) bremsstrahlung SPECT imaging in selective internal radiation therapy, and to use this method to improve quantitative comparison of predicted and delivered Y absorbed doses.

Methods: The spatial resolution of Tc SPECT data was converted to that of Y SPECT data using a function calculated from Tc and Y point spread functions. This resolution conversion method (RCM) was first applied to Tc and Y SPECT phantom data to validate the method, and then to clinical data to assess the power of Tc SPECT imaging to predict the therapeutic absorbed dose.

Characterization of the aroma compounds of Millet Huangjiu at different fermentation stages.

Food Chem 2021 Jul 24;366:130691. Epub 2021 Jul 24.

Shaanxi Provincial Research Center of Functional Food Engineering Technology, Xi'an, China.

Millet Huangjiu (MHJ), a type of northern Huangjiu with a long history, has attracted considerable attention in China and East Asia for its unique flavor. To elucidate the changing course of aroma components during the fermentation process of MHJ, 15 MHJ samples prepared at different fermentation stages were assessed by gas chromatography-olfactometry (GC-O) and odor activity value (OAV) coupled with multivariate data analysis. A total of 66 volatile compounds were identified, among which 21 odorant active substances were regarded as the main aroma components (OAVs ≥ 1). Read More

Analyzing drivers' hazard recognition: Precursors to single-vehicle collisions.

Accid Anal Prev 2021 Jul 30;160:106304. Epub 2021 Jul 30.

Department of Civil & Environmental Engineering, The University of Tennessee, Knoxville, United States.

Extensive driver behavior and performance information provided by real-world video surveillance and sensor data in the SHRP2 Naturalistic Driving Study has enabled the examination of new layers and pathways leading to crash outcomes. We note that the prominence of hazards and the importance of recognizing them vary systematically across single vs. multi-vehicle crashes, and address a fundamental question about safety: why do around three-quarters of drivers involved in single-vehicle crashes not recognize, perceive, or react to the precipitating event (PE)? Using a path-analytic framework through marginal effects, this study investigates factors correlated to recognition of the PE in single-vehicle events, and how these correlations may act as crash precursors.

Peking University Sixth Hospital, Peking University Institute of Mental Health, NHC Key Laboratory of Mental Health (Peking University), National Clinical Research Center for Mental Disorders (Peking University Sixth Hospital), Peking University, Beijing, China. Electronic address:

The 21st Century Cures Act passed by the United States (US) Congress in December 2016 requires the US Food and Drug Administration (FDA) shall establish a program to evaluate the potential use of real-world evidence (RWE) which is generated from real-world data (RWD) to (i) support approval of new indication for a drug approved under section 505 (c) and (ii) satisfy post-approval study requirements. RWE offers the opportunities to develop robust evidence using high-quality data and sophisticated methods for producing causal-effect estimates regardless randomization is feasible. In this article, we have demonstrated that the assessment of treatment effect (RWE) based on RWD could be biased due to the potential selection and information biases of RWD. Read More
