Artificial Intelligence in Pathology: Easing the Burden of Annotation Running Title: AI Annotation Reduction.

Am J Pathol 2021 Jun 12. Epub 2021 Jun 12.

Emeritus Professor, Rutgers-NJMS; Department of Pathology and Laboratory Medicine Adjunct Professor, Perelman Medical School; Adjunct Professor, Sidney Kimmel School of Medicine, Philadelphia, PA. Electronic address:

The need for huge datasets represents a bottleneck for applications of artificial intelligence. In Pathology, an additional problem is that there are often substantially fewer annotated target lesions than normal tissues for comparison. Organic brains overcome these limitations by utilizing large numbers of specialized neural nets arranged in both linear and parallel fashion, with each solving a restricted classification problem.

Constructing High-Fidelity Phenotype Knowledge Graphs for Infectious Diseases With a Fine-Grained Semantic Information Model: Development and Usability Study.

J Med Internet Res 2021 Jun 15;23(6):e26892. Epub 2021 Jun 15.

Suzhou Institute of Systems Medicine, Suzhou, China.

Background: Phenotypes characterize the clinical manifestations of diseases and provide important information for diagnosis. Therefore, the construction of phenotype knowledge graphs for diseases is valuable to the development of artificial intelligence in medicine. However, phenotype knowledge graphs in current knowledge bases such as WikiData and DBpedia are coarse-grained knowledge graphs because they only consider the core concepts of phenotypes while neglecting the details (attributes) associated with these phenotypes.

MXene and black phosphorus based 2D nanomaterials in bioimaging and biosensing: progress and perspectives.

J Mater Chem B 2021 Jun 15. Epub 2021 Jun 15.

Center for Biomedical Photonics & College of Physics and Optoelectronic Engineering, Shenzhen University, Shenzhen 518060, China.

Bioimaging and biosensing have garnered interest in early cancer diagnosis due to the ability of gaining in-depth insights into cellular functions and providing a wide range of diagnostic parameters. Emerging 2D materials of multielement MXenes and monoelement black phosphorous nanosheets (BPNSs) with unique intrinsic physicochemical properties such as a tunable bandgap and layer-dependent fluorescence, high carrier mobility and transport anisotropy, efficient fluorescence quenching capability, desirable light absorption and thermoelastic properties, and excellent biocompatibility and biosafety properties provide promising nano-platforms for bioimaging and biosensing applications. In view of the growing attention on the rising stars of the post-graphene age in the progress of bioimaging and biosensing, and their common feature characteristics as well as complementarity for constructing complexes, the main objective of this review is to reveal the recent advances in the design of MXene or BPNS based nanoplatforms in the field of bioimaging and biosensing.

Novel Digital Technologies for Blood Pressure Monitoring and Hypertension Management.

Curr Cardiovasc Risk Rep 2021 9;15(8):11. Epub 2021 Jun 9.

Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA USA.

Purpose Of Review: Hypertension is common, impacting an estimated 108 million US adults, and deadly, responsible for the deaths of one in six adults annually. Optimal management includes frequent blood pressure monitoring and antihypertensive medication titration, but in the traditional office-based care delivery model, patients have their blood pressure measured only intermittently and in a way that is subject to misdiagnosis with white coat or masked hypertension. There is a growing opportunity to leverage our expanding repository of digital technology to reimagine hypertension care delivery. Read More

Inferring statistical trends of the COVID19 pandemic from current data.Where probability meets fuzziness.

Authors:
Bruno Apolloni

Inf Sci (N Y) 2021 Jun 9. Epub 2021 Jun 9.

Department of Computer Science, via Comelico 39/41, Milano, 20135, Italy.

We introduce unprecedented tools to infer approximate evolution features of the COVID19 outbreak when these features are altered by containment measures. In this framework we present: 1) a basic tool to deal with samples that are both truncated and non independently drawn, and 2) a two-phase random variable to capture a game changer along a process evolution. To overcome these challenges we lie in an intermediate domain between probability models and fuzzy sets, still maintaining probabilistic features of the employed statistics as the reference KPI of the tools.

Metabolomic profiling of single enlarged lysosomes.

Nat Methods 2021 Jun 14. Epub 2021 Jun 14.

Institute on Aging and Brain Disorders, the First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, Hefei National Laboratory for Physical Sciences at the Microscale, University of Science and Technology of China, Hefei, China.

Lysosomes are critical for cellular metabolism and are heterogeneously involved in various cellular processes. The ability to measure lysosomal metabolic heterogeneity is essential for understanding their physiological roles. We therefore built a single-lysosome mass spectrometry (SLMS) platform integrating lysosomal patch-clamp recording and induced nano-electrospray ionization (nanoESI)/mass spectrometry (MS) that enables concurrent metabolic and electrophysiological profiling of individual enlarged lysosomes.

Continuous-wave near-infrared stimulated-emission depletion microscopy using downshifting lanthanide nanoparticles.

Nat Nanotechnol 2021 Jun 14. Epub 2021 Jun 14.

Department of Chemistry, National University of Singapore, Singapore, Singapore.

Stimulated-emission depletion (STED) microscopy has profoundly extended our horizons to the subcellular level. However, it remains challenging to perform hours-long, autofluorescence-free super-resolution imaging in near-infrared (NIR) optical windows under facile continuous-wave laser depletion at low power. Here we report downshifting lanthanide nanoparticles that enable background-suppressed STED imaging in all-NIR spectral bands (λ = 808 nm, λ = 1,064 nm and λ = 850-900 nm), with a lateral resolution of below 20 nm and zero photobleaching.

Yet Another Automated Gleason Grading System (YAAGGS) by weakly supervised deep learning.

NPJ Digit Med 2021 Jun 14;4(1):99. Epub 2021 Jun 14.

Deep Bio Inc., Seoul, South Korea.

The Gleason score contributes significantly in predicting prostate cancer outcomes and selecting the appropriate treatment option, which is affected by well-known inter-observer variations. We present a novel deep learning-based automated Gleason grading system that does not require extensive region-level manual annotations by experts and/or complex algorithms for the automatic generation of region-level annotations. A total of 6664 and 936 prostate needle biopsy single-core slides (689 and 99 cases) from two institutions were used for system discovery and validation, respectively. Read More

A machine learning approach to predict healthcare cost of breast cancer patients.

Sci Rep 2021 Jun 14;11(1):12441. Epub 2021 Jun 14.

Basque Center for Applied Mathematics, Bilbao, Spain.

This paper presents a novel machine learning approach to perform an early prediction of the healthcare cost of breast cancer patients. The learning phase of our prediction method considers the following two steps: (1) in the first step, the patients are clustered taking into account the sequences of actions undergoing similar clinical activities and ensuring similar healthcare costs, and (2) a Markov chain is then learned for each group to describe the action-sequences of the patients in the cluster. A two step procedure is undertaken in the prediction phase: (1) first, the healthcare cost of a new patient's treatment is estimated based on the average healthcare cost of its k-nearest neighbors in each group, and (2) finally, an aggregate measure of the healthcare cost estimated by each group is used as the final predicted cost.
