Early post-operative endoscopic recurrence in Crohn's disease patients: data from an Italian Group for the study of inflammatory bowel disease (IG-IBD) study on a large prospective multicenter cohort

The incidence of endoscopic recurrence in Crohn's disease following curative resection is up to 75% at 1 year. The study suggests post-surgical endoscopic evaluation should be performed at 6 months instead of 1 year to allow an adequate early treatment.

Training and transfer of colonoscopy skills: a multinational, randomized, blinded, controlled trial of simulator versus bedside training

Simulator training significantly improved performance on simulated cases compared with patient-based training. Novices in the simulator group demonstrated superior technical skills.

Efficacy and safety of certolizumab pegol in an unselected crohn's disease population: 26-week data of the FACTS II survey

This prospective phase IV study aimed to evaluate the efficacy and safety. Response and remission rates were 70% and 40% (week 6) and 67% and 36%, respectively.

The ACCURE-trial: the effect of appendectomy on the clinical course of ulcerative colitis, a randomised international multicenter trial (NTR2883) and the ACCURE-UK trial: a randomised external pilot trial (ISRCTN56523019)

Appendectomy might alter the clinical course of established UC. The objective of this body of research is to evaluate the short-term and medium-term efficacy of appendectomy to maintain remission in patients with UC.

Clinical Characteristics and Viral RNA Detection in Children With Coronavirus Disease 2019 in the Republic of Korea

In this case series study, inapparent infections in children may have been associated with silent COVID-19 transmission in the community. The mean (SD) duration of the presence of SARS-CoV-2 RNA in upper respiratory samples was 17.6 (6.7) days in asymptomatic individuals.

Prolonged SARS-CoV-2 detection and reversed RT-PCR results in mild or asymptomatic patients

In 23% (69/300) of patients, SARS-CoV-2 was detected more than 3 weeks after the initial positive RT-PCR. In 14% (42/300), the RT- PCR results were positive for more than 4 weeks.

Prevalence of SARS-CoV-2 IgG antibodies in an area of northeastern Italy with a high incidence of COVID-19 cases: a population-based study

The study was conducted in a high-incidence area located in northeastern Italy. A total of 1402 participants were positive for IgG antibodies against SARS-CoV-2, with a prevalence of 23.1% (1402/6075) The infection fatality rate was 2.5% (35/1402).

Analytical sensitivity and clinical sensitivity of the three rapid antigen detection kits for detection of SARS-CoV-2 virus

RAD kits for diagnosing COVID-19 patients are available in the market. Clinical sensitivity of RAD kits ranged from 22.9%-71.4% for detecting SARS-CoV-2 virus.
