Nomogram to Predict the Overall Survival of Colorectal Cancer Patients: A Multicenter National Study.

Background: Colorectal cancer (CRC) is the third foremost cause of cancer-related death and the fourth most commonly diagnosed cancer globally. The study aimed to evaluate the survival predictors using the Cox Proportional Hazards (CPH) and established a novel nomogram to predict the Overall Survival (OS) of the CRC patients.

Materials And Methods: A historical cohort study, included 1868 patients with CRC, was performed using medical records gathered from Iran's three tertiary colorectal referral centers from 2006 to 2019.

Survival analysis in gastric cancer: a multi-center study among Iranian patients.

Background: Gastric cancer (GC) has been considered as the 5th most common type of cancer and the third leading cause of cancer-associated death worldwide. The aim of this historical cohort study was to evaluate the survival predictors for all patients with GC using the Cox proportional hazards, extended Cox, and gamma-frailty models.

Methods: This historical cohort study was performed according to documents of 1695 individuals having GC referred to three medical centers in Iran from 2001 to 2018.

Catechol-O-methyltransferase gene expression in stress-induced and non-stress induced schizophrenia.

Introduction: As schizophrenia is a complex mental disorder and the outcome of gene-gene-environmental interactions, there are different possible pathophysiological mechanisms in different schizophrenia subtypes corresponding to various risk factors. This study was aimed at examining the impact of one of the most likely interactions, that is, 'dopamine and stress', in schizophrenia pathogenesis.

Methods: Here, we investigated the interaction between 'war-related psychological trauma' without brain trauma and catechol-O-methyltransferase gene.

A rare case of right-sided heart failure after bentall procedure.

Pseudoaneurysms of the ascending aorta, which are rare and life-threatening complications in cardiovascular surgeries, can be caused by the Bentall procedure. We describe a 44-year-old woman, who had a medical history of acute aortic dissection (Type A) and the Bentall procedure and was admitted because of exertional dyspnea, edema of the lower extremities, ascites, and holosystolic murmur in the left lower sternal border. Preoperative echocardiography revealed a pseudoaneurysm of the ascending aorta and fistulization of the pseudoaneurysm to the right atrium.
