NeoUNet: Towards accurate colon polyp segmentation and neoplasm detection [PDF]

arXiv, 2021
Automatic polyp segmentation has proven to be immensely helpful for endoscopy procedures, reducing the missing rate of adenoma detection for endoscopists while increasing efficiency. However, classifying a polyp as being neoplasm or not and segmenting it at the pixel level is still a challenging task for doctors to perform in a limited time.

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 ...

Bowel cleansing efficacy of 1 L NER1006 versus macrogol and 3 L polyethylene glycol using split‐dose administration

JGH Open, Volume 6, Issue 12, Page 824-832, December 2022., 2022
In Australia, high‐volume polyethylene glycol based bowel preparations is our gold standard to achieve acceptable levels of colon cleansing for a colonoscopy. Yet, the rebooking rates and subsequent costs to the health service warranted further investigation to determine whether other bowel preparation options were more effective, while maintaining a ...

Brain tumor multi classification and segmentation in MRI images using deep learning [PDF]

arXiv, 2023
This study proposes a deep learning model for the classification and segmentation of brain tumors from magnetic resonance imaging (MRI) scans. The classification model is based on the EfficientNetB1 architecture and is trained to classify images into four classes: meningioma, glioma, pituitary adenoma, and no tumor.

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.

Endoscopy training in Australia during COVID‐19: Efficacy and knowledge assessment of gastroenterology and general surgery trainees

JGH Open, Volume 6, Issue 12, Page 869-875, December 2022., 2022
During COVID‐19, restrictions to elective procedures were introduced worldwide. Our study aimed to assess Australian advanced Gastroenterology and General Surgery trainees' self‐perceived efficacy and knowledge in endoscopy during the pandemic. We have found that although self‐efficacy in endoscopic diagnostic procedures was achieved for most trainees,

Detection of Colon Polyps in India—A Large Retrospective Cohort Study (DoCPIr)

Journal of Digestive Endoscopy, 2021
Objective Colorectal cancer (CRC) is an emerging public health problem in Asia and India. However, there is scarcity of data on CRC and adenoma. We aimed to study prevalence and characteristics of colonic polyps in a large retrospective cohort.

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.
