Computer-assisted diagnosis techniques (dermoscopy and spectroscopy-based) for diagnosing skin cancer in adults.

Cochrane Database Syst Rev 2018 Dec 3;12:CD013186. Epub 2018 Dec 3.

Institute of Applied Health Research, University of Birmingham, Edgbaston Campus, Birmingham, UK, B15 2TT.

Background: Early accurate detection of all skin cancer types is essential to guide appropriate management and to improve morbidity and survival. Melanoma and cutaneous squamous cell carcinoma (cSCC) are high-risk skin cancers which have the potential to metastasise and ultimately lead to death, whereas basal cell carcinoma (BCC) is usually localised with potential to infiltrate and damage surrounding tissue. Anxiety around missing early curable cases needs to be balanced against inappropriate referral and unnecessary excision of benign lesions. Read More

Cortex 2018 Nov 1;111:210-237. Epub 2018 Nov 1.

Department of Linguistics, Neuroscience Program, Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign, USA. Electronic address:

Many neurocognitive accounts of language processing presume that neural responses detected in grand mean analyses of cortical electrophysiological activity reflect the normative brain response in the population under investigation. However, emerging work now shows that individuals' brain responses can vary systematically in both the size and type of effect elicited. The present research therefore examined individual differences in neural activity elicited by grammatical agreement anomalies during language comprehension in a large cohort of highly literate, monolingual English speakers (N = 114), a population generally assumed to be relatively homogenous in terms of linguistic knowledge and processing.

The dysregulation profile in preschoolers with and without a family history of autism spectrum disorder.

J Child Psychol Psychiatry 2018 Dec 1. Epub 2018 Dec 1.

Department of Psychiatry & Behavioral Sciences, MIND Institute, University of California, Davis, Sacramento, CA, USA.

Background: The 'dysregulation profile' (DP) is a measure of emotional and behavioral dysregulation that may cut across diagnostic boundaries. Siblings of children with autism spectrum disorder (ASD) who do not develop ASD themselves are at risk for atypical outcomes including behavioral challenges and therefore may be a useful population in which to investigate the structure of the DP in preschoolers.

Methods: We sought to examine the factor structure and predictors of the DP in a sample enriched for a wide range of phenotypic variation-36-month-olds with and without family histories of ASD-and to determine whether children with genetic liability for ASD are at risk for a phenotype characterized by elevated dysregulation.

Robustness of the non-neuronal cholinergic system in rat large intestine against luminal challenges.

Pflugers Arch 2018 Dec 1. Epub 2018 Dec 1.

Institute for Veterinary Physiology and Biochemistry, Justus Liebig University Giessen, Giessen, Germany.

Acetylcholine and atypical esters of choline such as propionyl- and butyrylcholine are produced by the colonic epithelium and are released when epithelial receptors for short-chain fatty acids (SCFA) are stimulated by propionate. It is assumed that the SCFA used by the choline acetyltransferase (ChAT), the central enzyme for the production of these choline esters, originate from the colonic lumen, where they are synthesized during the bacterial fermentation of carbohydrates. Therefore, it seemed to be of interest to study whether the non-neuronal cholinergic system in the colonic epithelium is affected by maneuvers intended to stimulate or to inhibit colonic fermentation by changing the intestinal microbiota.

Genre-typical narrative arcs in films are less appealing to lay audiences and professional film critics.

Behav Res Methods 2018 Nov 30. Epub 2018 Nov 30.

Texas Tech University, Lubbock, TX, USA.

People tend to like stimuli-ranging from human faces to text-that are prototypical, and thus easily processed. However, recent research has suggested that less typical stimuli may be preferred in creative contexts, such as fine art or music lyrics.

Second International Consensus Conference on lesions of uncertain malignant potential in the breast (B3 lesions).

Breast Cancer Res Treat 2018 Nov 30. Epub 2018 Nov 30.

Institute of Pathology and Molecular Pathology, University Hospital Zurich, Switzerland Schmelzbergstrasse 12., 8091, Zurich, Switzerland.

Purpose: The second International Consensus Conference on B3 lesions was held in Zurich, Switzerland, in March 2018, organized by the International Breast Ultrasound School to re-evaluate the consensus recommendations.

Methods: This study (1) evaluated how management recommendations of the first Zurich Consensus Conference of 2016 on B3 lesions had influenced daily practice and (2) reviewed current literature towards recommendations to biopsy.

Results: In 2018, the consensus recommendations for management of B3 lesions remained almost unchanged: For flat epithelial atypia (FEA), classical lobular neoplasia (LN), papillary lesions (PL) and radial scars (RS) diagnosed on core-needle biopsy (CNB) or vacuum-assisted biopsy (VAB), excision by VAB in preference to open surgery, and for atypical ductal hyperplasia (ADH) and phyllodes tumors (PT) diagnosed at VAB or CNB, first-line open surgical excision (OE) with follow-up surveillance imaging for 5 years.
