The IRR for snare removal of polyps 1-20 mm was 13.8% (95% CI, 10.3-17.3; 13 studies, 5128 polypectomies). IRRs were 15.9% for snare removal of polyps 1-10 mm (95% CI, 9.6-22.1; 9 studies, 2531 polypectomies) and 20.8% for snare removal of polyps 10-20 mm (95% CI, 12.9-28.8; 6 studies, 412 polypectomies). The IRR for hot snare removal of polyps 1-10 mm was 14.2% (95% CI, 5.2-23.2) vs 17.3% for cold-snare polypectomy (95% CI, 14.3‒20.3). The IRR for forceps removal of polyps 1-5 mm was 9.9% (95% CI, 7.1-13.0) vs 4.4% for snare polypectomy (95% CI, 2.9-6.1). Conclusions In a systematic review and meta-analysis, we found that colorectal polyps 1-20 mm are frequently incompletely resected, and that risk increases for polyps 10 mm or larger. There is no difference in IRRs of cold vs hot snares for polyps 1-10 mm. Snare polypectomy should be used over forceps for polyps 1-5 mm.Schizophrenia is a severe and chronic mental disease with a high prevalence and a variety of symptoms. Data from behavioural studies suggest that it is rational to investigate the endocannabinoid system (ECS) and its cannabinoid receptor (CBr) because they seem to underlie susceptibility to schizophrenia, and these findings have pointed to several lines of future research. Currently, most available studies address the role of CBr type 1 in schizophrenia-like responses. Here, we present for the first time, a review that demonstrates the pivotal role of CBr type 2 in the regulation of neurobiological processes underlying cognition, psychosis- and mood-related (anxiety, depression) behaviours, all of which may be included in schizophrenia symptoms. This review is based on available evidence from the PubMed database regarding schizophrenia-like symptoms induced via CB2r modulation in various animal models. The data presented in th
