Nomogram for predicting overall survival time of patients with stage IV colorectal cancer.

Background: Prognosis varies among stage IV colorectal cancer (CRC). Our study aimed to build a robust prognostic nomogram for predicting overall survival (OS) of patients with stage IV CRC in order to provide evidence for individualized treatment.

Method: We collected the information of 16,283 patients with stage IV CRC in the Surveillance, Epidemiology, and End Results (SEER) database and then randomized these patients in a ratio of 7:3 into a training cohort and an internal validation cohort.

Case Report: Bilateral Corneal Ectasia Developed during Pregnancy after Small-incision Lenticule Extraction.

Significance: This case highlights that hormonal changes during pregnancy could affect the biomechanical stability of the cornea and lead to corneal ectasia during pregnancy after corneal refractive surgery.

Purpose: We report an unusual case of bilateral corneal ectasia after small-incision lenticule extraction that developed during pregnancy.

Case Report: A 27-year-old woman experienced post-small-incision lenticule extraction corneal ectasia.

Increased risk of colorectal neoplasia in inflammatory bowel disease patients with post-inflammatory polyps: A systematic review and meta-analysis.

Background: Inflammatory bowel disease (IBD) patients with post-inflammatory polyps (PIPs) may carry an increased risk of colorectal neoplasia (CRN) including dysplasia and cancer. Current guidelines recommend active colonoscopy follow-up for these patients. However, the evidence for guidelines is still poor.

Risk factors and incidence of suction loss during small incision lenticule extraction (SMILE) in 8493 eyes.

Background: To report the incidence and risk factors of suction loss during small incision lenticule extraction (SMILE).

Methods: This retrospective comparative case control study included 8493 eyes of 4261 patients. Patients underwent SMILE surgery between January 2014 and September 2019 were included.
