Abstract Background Machine learning (ML) is a significant area of artificial intelligence, which can improve the accuracy predictive or diagnostic models for differentiating between prostate biopsy outcomes. This study aims to develop novel decision-support ML model classifying patients with biopsy-negative (cancer-free), clinically significant, and non-clinically cancer across two prostate-specific antigen (PSA) cut-offs ≤ 10 ng/ml > ng/ml. Methods The data current were retrieved from...

Background Despite Saudi Arabia's sunny climate, vitamin D deficiency is prevalent. We aimed to utilize several machine learning algorithms predict Vitamin among men and identify correlated features. Methods collected data from the records of King Khalid University Hospital in Riyadh between 2019 2021. Variables included health conditions, race, blood pressure, BMI, glucose, lipid profile, total 25-hydroxyvitamin (25OHD) levels. Six ML (Support Vector Machine, decision tree, linear...

We report a very rare case of invasive squamous cell carcinoma (SCC) in the abdominal stoma Monti ileovesicostomy. Our patient underwent an uncomplicated ileovesicostomy at age 16 for neurogenic bladder. She presented 10 years later with difficulty catheterizing stoma. A biopsy peristomal tissue showed moderately differentiated SCC. cystoscopy did not reveal any bladder tumours or suspicious lesions. computed tomography (CT) scan abdomen and pelvis demonstrate metastasis.

Abstract Purpose. To investigate the role of mTOR signalling pathway on stage and outcome patients with high grade and/or invasive bladder cancer. Methods. Tissue microarrays were built from archival mostly superficial tumour specimens (n=143 complete clinical data collected). Immunohistochemical staining was performed for Phosphatase tensin homolog (Pten), phosphorylated (phos) Akt, phos-mTOR, phos-S6, phos-4EBP1 p27. The markers evaluated pattern, percentage intensity (H-score), results...
