Oncology: etymology of the term.

Med Oncol 2021 Feb 9;38(3):22. Epub 2021 Feb 9.

Graduate School of Arts and Social Science, Maastricht University, Maastricht, The Netherlands.

The OED lists oncologia (a Latinization of Greek ογκολογία, ὄγκος + λόγια) as a dictionary term attested from 1860. The neoclassical term is much older, however. The neo-Greek term was used in the title of two seventeenth-century medical tracts on assorted tumors, first in a 1618 medical dissertation by Balthasar Simon. Read More

'On the different Species of Phobia' and 'On the different Species of Mania' (1786): from popular furies to mental disorders in America.

Med Humanit 2020 Dec 14. Epub 2020 Dec 14.

Graduate School of Arts and Social Sciences, Maastricht University, Maastricht, The Netherlands

Benjamin Rush's twin 1786 letters on the different species of phobia and mania sit at an extended historical juncture at which an early modern quasi-medical troping of mental disorder in American social commentary sobered up to mental medicine. The letters' satirical drive hinged on a perennial problem still occupying George Beard almost a century onward: which idiosyncratic trepidation or ill-grounded idea warranted the nomination of national and epochal ill? Rush's mania letter exemplified an established genre identifying popular and especially political crazes; at the same time, it foreshadowed the early 19th-century rise and mid-century fall of monomania as forensic-nosological stopgap. The phobia text established the term's dictionary (OED) sense of specific morbid fears, but did so in the form of a mobilisation of nosological jargon for social diagnostics purposes: an ambivalent prelude to Rush's later formal engagement with unreasonable fears and follies.

Gaussian Process Based Expected Information Gain Computation for Bayesian Optimal Design.

Entropy (Basel) 2020 Feb 24;22(2). Epub 2020 Feb 24.

School of Information Science and Technology, ShanghaiTech University, Shanghai 201210, China.

Optimal experimental design (OED) is of great significance in efficient Bayesian inversion. A popular choice of OED methods is based on maximizing the expected information gain (EIG), where expensive likelihood functions are typically involved. To reduce the computational cost, in this work, a novel double-loop Bayesian Monte Carlo (DLBMC) method is developed to efficiently compute the EIG, and a Bayesian optimization (BO) strategy is proposed to obtain its maximizer only using a small number of samples.

Oral epithelial reactive atypia/dysplasia: An underestimated true atypia/dysplasia?

Med Hypotheses 2020 Nov 26;144:110217. Epub 2020 Aug 26.

Oral Medicine Department, Facultad de Odontología, Universidad Nacional de Córdoba, Argentina.

Several clinical and histological features, usually associated with chronic inflammation could complexify the diagnosis of oral epithelial dysplasia (OED). These changes in response to inflammatory stimuli, or re-epithelialization events, are described as reactive epithelial atypia or dysplasia (REA/D). Within a REA/D scenario (for example in the edges of chronic traumatic ulcers), the diagnosis of OED could be challenging for oral pathologists due to an unfeasibility to accurate the true nature of that changes.

Non-Invasive Diagnostic System Based on Light for Detecting Early-Stage Oral Cancer and High-Risk Precancerous Lesions-Potential for Dentistry.

Cancers (Basel) 2020 Oct 29;12(11). Epub 2020 Oct 29.

Department of Oral Medicine and Stomatology, School of Dental Medicine, Tsurumi University, 2-1-3 Tsurumi, Tsurumi-ku, Yokohama City, Kanagawa 230-8501, Japan.

Oral health promotion and examinations have contributed to the early detection of oral cancer and oral potentially malignant disorders, leading to the adaptation of minimally invasive therapies and subsequent improvements in the prognosis/maintenance of the quality of life after treatments. However, the accurate detection of early-stage oral cancer and oral epithelial dysplasia is particularly difficult for conventional oral examinations because these lesions sometimes resemble benign lesions or healthy oral mucosa tissues. Although oral biopsy has been considered the gold standard for accurate diagnosis, it is deemed invasive for patients. Read More

Temporal Dynamics of Learning Center, University of California San Diego, La Jolla, CA 92093.

Do dopaminergic reward structures represent the expected utility of information similarly to a reward? Optimal experimental design models from Bayesian decision theory and statistics have proposed a theoretical framework for quantifying the expected value of information that might result from a query. In particular, this formulation quantifies the value of information before the answer to that query is known, in situations where payoffs are unknown and the goal is purely epistemic: That is, to increase knowledge about the state of the world. Whether and how such a theoretical quantity is represented in the brain is unknown. Read More
