Predictive factors of surgery in metastatic colorectal cancer: a retrospective cohort study.

Introduction: Current management of metastatic colorectal cancer is based on neoadjuvant chemotherapy. Few studies have reported on surgery procedures in patients with metastatic colorectal cancer. The objective of this study was to describe our institutional experience with emergency surgery performed in patients with metastatic colorectal cancer during chemotherapy.

Low-dose penicillin in early life induces long-term changes in murine gut microbiota, brain cytokines and behavior.

There is increasing concern about potential long-term effects of antibiotics on children's health. Epidemiological studies have revealed that early-life antibiotic exposure can increase the risk of developing immune and metabolic diseases, and rodent studies have shown that administration of high doses of antibiotics has long-term effects on brain neurochemistry and behaviour. Here we investigate whether low-dose penicillin in late pregnancy and early postnatal life induces long-term effects in the offspring of mice.

Laparoscopic versus open techniques in rectal cancer surgery: a retrospective analysis of 121 sphincter-saving procedures in a single institution.

Background: There are few reports that show that laparoscopic rectal surgery for rectal cancer had similar oncological results based on short-term benefits. The purpose of this study was to analyze our institutional short- and long-term results in laparoscopic rectal surgery and to compare these results with that reported in the literature.

Methods: The records of 121 patients who underwent sphincter-saving procedure for rectal cancer were reviewed.
