Background: The inflammatory bowel disease (IBD) disk is a simple and quick method to assess the level of disability experienced by patients with IBD. It has been already translated and validated in European countries, however it was not yet translated and validated to use in Brazil.
Objective: This study was performed to translate and validate a Brazilian version of the IBD-Disk.
Tumor hypoxia may compromise the results of chemotherapy for treating colorectal cancer because it stimulates angiogenesis and the release of tumor growth factors. Hyperbaric oxygen (HBO) supplementation may potentiate the effects of chemotherapy in such cases. This study aimed to assess the effect of HBO therapy combined with chemotherapy on the treatment of colorectal cancer in mice.

Classically, experimental models of CRC in mice have been evaluated through clinical or serial euthanasia. The present study aims to investigate the role of low endoscopy in the analysis of carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG).

Objective: To evaluate the prevalence of pelvic dysfunction in patients with evacuation disorders through clinical and manometric findings and to evaluate, using the same findings, whether there are published protocols that could be guided by anorectal manometry.
Purpose To evaluate the gene expression of peroxisome proliferator activated receptors gamma (PPARG) in colorectal tumors and to correlate this data with clinical variables of the patients. Methods We analyzed the gene expression of PPARG in 50 samples of colorectal tumors using real-time reverse transcription polymerase chain reaction, and 20 adjacent normal tissue samples as control. The results of these quantifications were correlated with the respective patients' medical records' clinical information.

Methods: We analysed a prospective database of 39 patients submitted to a transanal endoscopic operation for rectal cancer after neoadjuvant chemoradiation between 2006 and 2015, comparing clinical and pathological variables, perioperative complications, recurrence rate and overall survival.
Results: We obtained 15.
Purpose: To describe a novel securing device for loop colostomies, developed in our institution and report our 10-year experience.
Methods: The T-shaped support device was used in all patients who required loop colostomy and who were at an increased risk of stoma withdrawal. The device was removed on the fifth postoperative day in all patients.
Introduction: Infliximab, an antibody against tumor necrosis factor alpha, is used to treat inflammatory bowel disease and has well-established efficacy and proven safety. Complications of this treatment are related to immunosuppression and include higher risk of serious infections and malignant neoplasia. Although extremely rare, fulminant liver damage related to infliximab therapy has been reported.

Aims: This work aimed at measuring longitudinally academic motivation, anxiety, depression and social adjustment in first-year medical students and determining the relationships between these variables and academic performance, as measured mainly by grades on regular exams.
Methods: Eighty-five first-year medical students (age: 17-25 years) were included after giving informed consent.
