Effectiveness and safety of 1-L PEG-ASC versus other bowel preparations for colonoscopy: A meta-analysis of nine randomized clinical trials.

BACKGROUND AND AIMS: A 1-L polyethylene glycol plus ascorbate (PEG-ASC) preparation has been recently developed to improve patients' experience in colonoscopy. This meta-analysis aimed to evaluate the effectiveness and safety of 1-L PEG-ASC compared with those of other bowel preparations for colonoscopy. METHODS: MEDLINE, Embase, Scopus, and the Cochrane Library were systematically searched for randomized controlled trials comparing 1-L PEG-ASC with other bowel preparations published through July 2022. A random-effects model was applied for pooling the results; heterogeneity was expressed as I2. RESULTS: Nine studies met the inclusion criteria and were included. The analysis showed significantly higher cleansing success (CS) (OR = 1.50; 95% CI = 1.25-1.81; p < 0.01, I2 = 0%) and right-colon high-quality cleansing (HQC) (OR = 1.67; 95% CI = 1.21-2.31; p < 0.01, I2 = 43%) with 1-L PEG-ASC compared to the other preparations. The pooled estimate of the adenoma detection rate (ADR) did not significantly differ between the two groups either in the overall (OR = 1.02; 95% CI = 0.87-1.20; p = 0.79, I2 = 0%) or split-dosing regimen subgroup analysis (OR = 0.99; 95% CI = 0.84-1.18; p = 0.94, I2 = 0%). A significantly higher pooled estimate of the number of patients with adverse events (AEs) (OR = 1.51; 95% CI = 1.23-1.84; p<0.01, I2 = 0%) and incidence of AEs (IRR=1.33; 95% CI = 1.11-1.58; p<0.01, I2 = 71%) was observed with 1-L PEG-ASC than with the other preparations. No serious AEs or deaths occurred. CONCLUSIONS: Compared to other preparations, 1-L PEG-ASC yielded higher overall CS, higher right-colon HQC rates, and similar ADR. The number of patients with AEs and incidence of the total AEs were significantly higher with 1-L PEG-ASC in the absence of serious AEs.

Effectiveness and safety of 1L PEG-ASC preparation for colonoscopy in patients with inflammatory bowel diseases.

INTRODUCTION: The effectiveness of bowel cleansing is a key element for high-quality colonoscopy. Recently, a 1 L polyethylene glycol plus ascorbate (PEG-ASC) solution has been introduced, but effectiveness and safety of this preparation have not been assessed in IBD patients. This study aims to evaluate effectiveness and safety of 1 L PEG-ASC solution in patients with IBD compared to controls. METHODS: We retrospectively analysed prospectively collected data on a cohort of 411 patients performing a colonoscopy after preparation with 1 L PEG-ASC, consecutively enrolled in 5 Italian centres. RESULTS: Overall, 185/411 (45%) were patients with IBD and 226/411 (55%) served as controls. A significantly higher cleansing success was achieved in IBD patients (92.9% vs 85.4%, p = 0.02). The multiple regression model showed that presence of IBD (OR=2.514, 95%CI=1.165-5.426; P = 0.019), lower age (OR=0.981, 95%CI=0.967-0.996; P = 0.014), split preparation (OR=2.430, 95%CI=1.076-5.492; P = 0.033), absence of diabetes (OR=2.848, 95%CI=1.228-6.605; P = 0.015), and of chronic constipation (OR=3.350, 95%CI=1.429-7.852; P = 0.005), were independently associated with cleansing success. The number of treatment-emergent adverse events (TEAEs) (51 vs 62%, p = 0.821), and of patients with TEAEs (22.2% vs 21.2%, p = 0.821), were similar in IBD patients and in controls, respectively. CONCLUSIONS: Results from this study support the effectiveness and safety of 1 L PEG-ASC solution in IBD patients, which may improve the definition of endoscopic outcomes both in Crohn's disease and ulcerative colitis.

Impact of the COVID-19 pandemic on Gastroenterology Divisions in Italy: A national survey.

BACKGROUND: In Italy, the spread of the COVID-19 pandemic has stressed the entire healthcare system and required a huge re-organization of many Divisions, including those of Gastroenterology. AIMS: to assess the impact of COVID-19 pandemic on Gastroenterology Divisions across Italy. METHODS: All members of the Italian Society of Gastroenterology (SIGE) were invited to answer a web-based survey. RESULTS: Data of 121 hospitals from all 20 Italian regions were analyzed. Overall, 10.7% Gastroenterology Divisions have been converted to Covid Units. Outpatients consultations, endoscopic and ultrasound procedures were limited to urgencies and oncology indications in 85.1%, 96.2% and 72.2% of Units, respectively, and 46.7% of them suspended the screening for colorectal cancer. Moreover, 72.2% of the staff received a training for use of personal protective equipment, although 45.5% did not have sufficient devices for adequate replacement. Overall, 132 healthcare workers in 41 Gastroenterology Divisions were found to be infected. CONCLUSION: This is the first study to evaluate, at a country level, the impact of COVID-19 outbreak on Gastroenterology Divisions. Substantial changes of practice and reduction of procedures have been recorded in the entire country. The long-term impact of such modifications is difficult to estimate but potentially very risky for many digestive diseases.

[Is there any correlation between psychiatric disease and the teaching profession?]. / Quale rischio di patologia psichiatrica per la categoria professionale degli insegnanti?

BACKGROUND: Some professional categories are at risk for burnout due to job-related stressors. Burnout is characterized by physical and emotional exhaustion, apathy, cynical attitude, low personal accomplishment and reduced self-control. Several studies on occupational stress have demonstrated that burnout has a strong impact on certain professions and in particular on teachers. OBJECTIVES: The purpose of the study was to highlight and compare differences among clinical disorders diagnosed in four different classes of workers in the Public Administration sector, with particular focus on job-related and mental disorders. MATERIALS AND METHODS: Based on the data collected in 3,447 medical examinations, performed by the Milan Health District from January 1992 to December 2003, in order to assess work fitness, researchers compared four categories of state employees (teachers, clerks, health care professionals and blue collars). RESULTS: The findings revealed that the risk of teachers to develop psychiatric disorders is 2-, 2.5-, and 3-fold higher than that of clerks, health care professionals and blue collars, respectively. Age or sex did not represent a confounding factor for increased rate of psychiatric disorders. Interestingly, teachers also presented an approximately 1.5-2 fold higher risk of developing neoplasms, compared with clerks and blue collars. CONCLUSIONS: The increased prevalence of psychiatric disorders among teachers that was detected in this cohort of state employees applying for a disability pension is striking and warrants further investigation. This finding points to the need for job-related interventions aimed at preventing teachers' psychiatric disorders, a multidimensional issue which requires active debate among institutions, unions, school authorities, the scientific community, professional associations and, last but not least, students and their families.
