Tumor-associated Stromal Cellular Density as a Predictor of Recurrence and Mortality in Breast Cancer: Results from Ethnically-diverse Study Populations.

Cancer Epidemiol Biomarkers Prev 2021 May 5. Epub 2021 May 5.

Division of Cancer Epidemiology and Genetics, National Cancer Institute.

Background: Tumor-associated stroma is comprised of fibroblasts, tumor infiltrating lymphocytes (TILs), macrophages, endothelial, and other cells, that interactively influence tumor progression through inflammation and wound repair. Although gene expression signatures reflecting wound repair predict breast cancer survival, it is unclear whether combined density of tumor-associated stromal cells, a morphological proxy for inflammation and wound repair signatures on routine hematoxylin and eosin (H&E)-stained sections, is of prognostic relevance.

Methods: By applying machine learning to digitized H&E-stained sections for 2,084 breast cancer patients from China (n=596; 24-55years), Poland (n=810; 31-75years), and the United States (n=678; 55-78years), we characterized tumor-associated stromal cellular density (SCD) as the percentage of tumor-stroma that is occupied by nucleated cells.

Outcome unpredictability affects outcome-specific motivation to learn.

Psychon Bull Rev 2021 May 4. Epub 2021 May 4.

Department of Psychology, Philipps-University Marburg, Gutenbergstrasse 18, 35052, Marburg, Germany.

Outcome predictability effects in associative learning paradigms describe better learning about outcomes with a history of greater predictability in a similar but unrelated task compared with outcomes with a history of unpredictability. Inspired by the similarities between this phenomenon and the effect of uncontrollability in learned helplessness paradigms, here, we investigate whether learning about unpredictability decreases outcome-specific motivation to learn. We used a modified version of the allergy task, in which participants first observe the foods eaten by a fictitious patient, followed by allergic reactions that he subsequently suffers, some of which are perfectly predictable and others unpredictable.

Weakly supervised temporal model for prediction of breast cancer distant recurrence.

Sci Rep 2021 May 4;11(1):9461. Epub 2021 May 4.

Department of Biomedical Informatics, Emory University School of Medicine, Atlanta, Georgia.

Efficient prediction of cancer recurrence in advance may help to recruit high risk breast cancer patients for clinical trial on-time and can guide a proper treatment plan. Several machine learning approaches have been developed for recurrence prediction in previous studies, but most of them use only structured electronic health records and only a small training dataset, with limited success in clinical application. While free-text clinic notes may offer the greatest nuance and detail about a patient's clinical status, they are largely excluded in previous predictive models due to the increase in processing complexity and need for a complex modeling framework.

A data-driven approach to violin making.

Sci Rep 2021 May 4;11(1):9455. Epub 2021 May 4.

Musical Acoustics Lab at the Violin Museum of Cremona, DEIB-Politecnico di Milano, Cremona Campus, Cremona, Italy.

Of all the characteristics of a violin, those that concern its shape are probably the most important ones, as the violin maker has complete control over them. Contemporary violin making, however, is still based more on tradition than understanding, and a definitive scientific study of the specific relations that exist between shape and vibrational properties is yet to come and sorely missed. In this article, using standard statistical learning tools, we show that the modal frequencies of violin tops can, in fact, be predicted from geometric parameters, and that artificial intelligence can be successfully applied to traditional violin making.

Machine learning based models for prediction of subtype diagnosis of primary aldosteronism using blood test.

Sci Rep 2021 May 4;11(1):9140. Epub 2021 May 4.

Department of Medicine and Bioregulatory Science, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi Higashi-ku, Fukuoka, 812-8582, Japan.

Primary aldosteronism (PA) is associated with an increased risk of cardiometabolic diseases, especially in unilateral subtype. Despite its high prevalence, the case detection rate of PA is limited, partly because of no clinical models available in general practice to identify patients highly suspicious of unilateral subtype of PA, who should be referred to specialized centers. The aim of this retrospective cross-sectional study was to develop a predictive model for subtype diagnosis of PA based on machine learning methods using clinical data available in general practice.
