Automated Cervical Digitized Histology Whole-Slide Image Analysis Toolbox.

J Pathol Inform

June 2021

Lister Hill National Center for Biomedical Communications, National Library of Medicine, National Institutes of Health, Bethesda, MD, USA.

Background: Cervical intraepithelial neoplasia (CIN) is regarded as a potential precancerous state of the uterine cervix. Timely and appropriate early treatment of CIN can help reduce cervical cancer mortality. Accurate estimation of CIN grade correlated with human papillomavirus type, which is the primary cause of the disease, helps determine the patient's risk for developing the disease.

Background: Although aortoiliac occlusive disease (AIOD) is preferentially treated endovascularly, some patients are still better served with an aortobifemoral bypass (ABF). For those patients, surgical treatment options include both standard open operations as well as laparoscopic ABF (LapABF). Several European centers perform LapABF with favorable results instead of open surgery, but this has not been widely embraced in the United States.

Background: Advances in image analysis and computational techniques have facilitated automatic detection of critical features in histopathology images. Detection of nuclei is critical for squamous epithelium cervical intraepithelial neoplasia (CIN) classification into normal, CIN1, CIN2, and CIN3 grades.

Methods: In this study, a deep learning (DL)-based nuclei segmentation approach is investigated based on gathering localized information through the generation of superpixels using a simple linear iterative clustering algorithm and training with a convolutional neural network.

Background: In previous research, we introduced an automated, localized, fusion-based approach for classifying uterine cervix squamous epithelium into Normal, CIN1, CIN2, and CIN3 grades of cervical intraepithelial neoplasia (CIN) based on digitized histology image analysis. As part of the CIN assessment process, acellular and atypical cell concentration features were computed from vertical segment partitions of the epithelium region to quantize the relative distribution of nuclei.

Methods: Feature data was extracted from 610 individual segments from 61 images for epithelium classification into categories of Normal, CIN1, CIN2, and CIN3.

Objective: Hospitalizations for acute asthma are thought to be highly preventable through the use of efficacious medications, though many patients have poor metered-dose inhaler (MDI) techniques, thus lessening these medications' real-world effectiveness. Teaching MDI techniques during hospitalization may therefore lead to improved outcomes. However, MDIs may be underutilized to deliver short-acting β-agonists (SABAs) in the inpatient setting, despite equivalent efficacy to nebulizer delivery.

CHD8 regulates neurodevelopmental pathways associated with autism spectrum disorder in neural progenitors.

Proc Natl Acad Sci U S A

October 2014

Molecular Neurogenetics Unit and Psychiatric and Neurodevelopmental Genetics Unit, Center for Human Genetic Research, Massachusetts General Hospital, Boston, MA 02114; Departments of Neurology and Broad Institute of M.I.T. and Harvard, Cambridge, MA 02142

Truncating mutations of chromodomain helicase DNA-binding protein 8 (CHD8), and of many other genes with diverse functions, are strong-effect risk factors for autism spectrum disorder (ASD), suggesting multiple mechanisms of pathogenesis. We explored the transcriptional networks that CHD8 regulates in neural progenitor cells (NPCs) by reducing its expression and then integrating transcriptome sequencing (RNA sequencing) with genome-wide CHD8 binding (ChIP sequencing). Suppressing CHD8 to levels comparable with the loss of a single allele caused altered expression of 1,756 genes, 64.

Autism spectrum disorders--a genetics review.

Genet Med

April 2011

Division of Medical Genetics, Department of Child Health, Thompson Center for Autism and Neurodevelopmental Disorders, University of Missouri Hospitals and Clinics, Columbia, MO 65211, USA.

Autism is an etiologically and clinically heterogeneous group of disorders, diagnosed solely by the complex behavioral phenotype. On the basis of the high-heritability index, geneticists are confident that autism will be the first behavioral disorder for which the genetic basis can be well established. Although it was initially assumed that major genome-wide and candidate gene association studies would lead most directly to common autism genes, progress has been slow.

Lack of association between Rh status, Rh immune globulin in pregnancy and autism.

Am J Med Genet A

July 2007

Thompson Center for Autism and Neurodevelopmental Disorders, and Department of Child Health, University of Missouri Hospitals and Clinics, 1 Hospital Drive, Columbia, MO 65212, USA.

Though causes of autism are considered largely genetic, considerable concern remains that exposure to Rh immune globulin (RhIg), which until 2001 in the United States contained the preservative thimerosal, can cause autism. To determine whether mothers of children with autism are more likely to be Rh negative (Rh(-)) or to have received RhIg preserved with thimerosal, which is 49.6% ethyl mercury, we surveyed families of children with an autism spectrum disorder (ASD) ascertained through a University-based autism clinic considered free of ascertainment biases related to type of autism or severity.
