How to improve the adenoma detection rate in colorectal cancer screening? Clinical factors and technological advancements

Archives of Medical Science, 2019
Introduction Colonoscopy has been widely regarded as the gold standard in colorectal cancer (CRC) screening. Within recent years different endoscopic imaging techniques have been introduced to improve the quality of colonoscopy.

Pituitary Adenoma Segmentation [PDF]

arXiv, 2011
Sellar tumors are approximately 10-15% among all intracranial neoplasms. The most common sellar lesion is the pituitary adenoma. Manual segmentation is a time-consuming process that can be shortened by using adequate algorithms. In this contribution, we present a segmentation method for pituitary adenoma.

A novel methodology for in vivo endoscopic phenotyping of colorectal cancer based on real-time analysis of the mucosal lipidome: a prospective observational study of the iKnife [PDF]

, 2016
Background: This pilot study assessed the diagnostic accuracy of rapid evaporative ionization mass spectrometry (REIMS) in colorectal cancer (CRC) and colonic adenomas. Methods: Patients undergoing elective surgical resection for CRC were recruited at St.

Functional Characterization of a Genetic Variant in the 5′ UTR of APC 1B Promoter in a Familial Adenomatous Polyposis Family

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Pathogenic germline variants in the APC gene result in familial adenomatous polyposis (FAP) which can escalate into colon cancer. Standard clinical testing failed to identify pathogenic variants in a 4‐generation FAP family. We identified and assessed co‐segregation of a 5′ untranslated region (UTR) variant, NM_001127511.3 (APC) c.‐40G>A ...

Dietary fiber intake and risk of colorectal cancer and incident and recurrent adenoma in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.

American Journal of Clinical Nutrition, 2015
BACKGROUND Dietary fiber has been associated with a reduced risk of colorectal cancer. However, it remains unclear at which stage in the carcinogenic pathway fiber may act or which food sources of dietary fiber may be most beneficial against colorectal ...

Cohesins: Crossroad Between Cornelia de Lange Spectrum and Cancer Predisposition

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The cohesin complex plays crucial roles in DNA repair, chromatid separation, and gene transcription regulation. Pathogenic variants in cohesins or dysfunctional transcriptional regulators lead to cohesinopathies, a broader group of disorders including Cornelia de Lange Spectrum (CdLSp), for which the prevalence of cancer cases remains unclear.

Gut microbiota‐stem cell niche crosstalk: A new territory for maintaining intestinal homeostasis

iMeta, Volume 1, Issue 4, December 2022., 2022
Intestinal stem cells (ISCs) are protected by their niche and are regulated by Wnt, bone morphogenetic protein, and Notch. ISCs and their relationship with intestinal microbiota provide a feasible pathway to alleviate intestinal diseases. Diverse bacteria‐related postbiotics regulate ISCs and maintain their homeostasis.

Adenomatous Tumors of the Middle Ear: A Literature Review

International Archives of Otorhinolaryngology, 2017
Introduction Neuroendocrine adenomas of the middle ear (NAME) are uncommon causes of middle ear masses. Mostly limited to case reports and small series, the literature is poor in providing an overall assessment of these tumors.

A Novel International Endoscopic Sphenoid Surgery Classification (IESSC): A Delphi Consensus

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Advancements in endoscopic sinus and skull base surgery created a need for standardized terminology to describe sphenoid sinus surgery. Although classification systems exist for other sinuses, one for endoscopic sphenoid sinus surgery is lacking.
