Introduction: With the advent of multiparametric MRI (mpMRI), clinicians added an important tool for helping to decide whether a man should undergo a prostate biopsy. The MRI PI-RADS system stratifies the risk of finding cancer on prostate biopsy. PI-RADS 3 lesions often prove to be a diagnostic challenge, and many men are advised not to proceed with a biopsy based on this finding. The goal of our paper was to evaluate the likelihood of finding cancer of clinical significance in this group. Methods: A retrospective 4-year data and quality analysis was performed of 312 evaluable men undergoing prostate MRI. Of the subset with scores of PI-RADS 3 who underwent biopsy (N = 32), 100 percent were biopsied using an MRI-guided fusion technique, greatly raising the likelihood that the MRI lesion was, in fact, the area sampled. Results: A total of 34% of the men with PI-RADS 3 lesions were found to have Grade Group ≥ 1, with 15.6 % demonstrating Grade Group ≥ 2. In the men with cancer, we analyzed and report the relationship to age, ethnicity, PSA density, and the presence or absence of cribriform findings. Conclusions: We found that many men with PI-RADS 3 findings on multiparametric MRI do, in fact, have clinically significant prostate cancer. We suggest that many factors (such as rate of rise of PSA over time, family history, and rectal examination findings) be considered in addition to the MRI PI-RADS score to advise whether or not to proceed with a biopsy of the prostate. Our findings, from a single, large, community hospital with a diverse ethnic makeup, parallel the findings of large trials done at academic centers of excellence. This demonstrates that comparable diagnostic mpMRI/biopsy quality may be found in the community setting.

Late Ordovician Mass Extinction: Earth, fire and ice

引用

National Science Review 2024年第1期11卷 51-65页

作者： david A.T.Harper Palaeoecosystems Group Department of Earth SciencesDurham University

The Late Ordovician Mass Extinction was the earliest of the ‘big’ five extinction events and the earliest to affect the trajectory of metazoan life. Two phases have been identified near the start of the Hirnantian period and in the middle. It was a massive taxonomic extinction, a weak phylogenetic extinction and a relatively benign ecological extinction. A rapid cooling, triggering a major ice age that reduced the temperature of surface waters, prompted a drop in sea level of some 100 m and introduced toxic bottom waters onto the shelves. These symptoms of more fundamental planetary processes have been associated with a range of factors with an underlying driver identified as volcanicity. Volcanic eruptions, and other products, may have extended back in time to at least the Sandbian and early Katian, suggesting the extinctions were more protracted and influential than hitherto documented.

作者： david Cheban Faculty of Mathematics and Computer Science Laboratory of Fundamental and Applied MathematicsMoldova State UniversityChisinau 2009Moldova

This work is devoted to the study of the dynamics of one-dimensional monotone nonautonomous(cocycle) dynamical systems. A description of the structures of their invariant sets, omega limit sets,Bohr/Levitan almost periodic and almost automorphic motions, global attractors, and pinched and minimalsets is given. An application of our general results is given to scalar differential and difference equations.

Kerogen Kinetic Distributions and Simulations Provide Insights into Petroleum Transformation Fraction (TF) Profiles of Organic-Rich Shales

Analysis of ancient mass extinction recoveries in marine environments: generating strategies for managing outcomes of the current mass extinction

引用

National Science Review 2024年第1期11卷 8-10页

作者： david J.Bottjer Department of Earth Sciences University of Southern California

The defining feature of a mass extinction and its associated recovery is the global amount of extinction that occurred[1]. However, there is finer-scale detail to the story, as seen in the ongoing modern mass extinction(the sixth mass extinction), which exhibits variable effects among marine ecosystems and environments, and hence geographic areas [1].
