Background: The incidence of early-onset colorectal cancer (EO-CRC) has been consistently rising leading to a significant cancer burden among younger adults in Asian and Middle Eastern high-income countries. The study aims to investigate the survival outcomes of EO-CRC among high-income Asian and Middle Eastern populations from 1990 to 2019 using the mortality-to-incidence ratio, with a focus on examining the differences in gender.

Methods: This is a systematic analysis of the Global Burden of Disease (GBD) 2019 study.

Early-Onset Colorectal Cancer Survival among Unscreened Population -Multicenter Cohort Retrospective Analysis.

Background: In Saudi Arabia and across the world, the incidence of early-onset colorectal cancer (< 50 years) has increased. The diagnosis of EOCRC, on the other hand, is frequently delayed. It is critical to implement a national screening program to identify those group of patients who might benefit from early diagnosis.

The emerging role of MCPH1/BRIT1 in carcinogenesis.

The MCPH1 gene, also known as BRCT-repeat inhibitor of hTERT expression (BRIT1), has three BRCA1 carboxyl-terminal domains which is an important regulator of DNA repair, cell cycle checkpoints and chromosome condensation. MCPH1/BRIT1 is also known as a tumour suppressor in different types of human cancer. The expression level of the MCPH1/BRIT1 gene is decreased at the DNA, RNA or protein level in a number of types of cancers including breast cancer, lung cancer, cervical cancer, prostate cancer and ovarian cancer compared to normal tissue.

An Infodemic of Misinformation on Stem Cell Therapy Among the Population of Saudi Arabia: A Cross-Sectional Study.

Unlabelled: In recent years, the industry of unproven stem cell-based therapies has been on the rise around the globe, putting patients at great risk of potential harm. In this cross-sectional study, we aimed to assess the level of knowledge and awareness of the general public, including patients and/or their relatives, in Saudi Arabia on stem cell therapy and to assess the degree of willingness to try stem cell-based treatment options, should it be offered to them.

Methods: A voluntary questionnaire of 16 questions was distributed randomly through social media outlets.

Living with the enemy: from protein-misfolding pathologies we know, to those we want to know.

Conformational diseases are caused by the aggregation of misfolded proteins. The risk for such pathologies develops years before clinical symptoms appear, and is higher in people with alpha-1 antitrypsin (AAT) polymorphisms. Thousands of people with alpha-1 antitrypsin deficiency (AATD) are underdiagnosed.

Using NMR spectroscopy to investigate the role played by copper in prion diseases.

Prion diseases are a group of rare neurodegenerative disorders that develop as a result of the conformational conversion of normal prion protein (PrP) to the disease-associated isoform (PrP). The mechanism that actually causes disease remains unclear. However, the mechanism underlying the conformational transformation of prion protein is partially understood-in particular, there is strong evidence that copper ions play a significant functional role in prion proteins and in their conformational conversion.

Molecular characterisation in tongue squamous cell carcinoma reveals key variants potentially linked to clinical outcomes.

Background: Oral tongue squamous cell carcinoma (OTSCC) is a highly aggressive malignancy characterized by frequent recurrence, poor survival with relatively few therapeutic options due to the late diagnosis in many cases.
