Sustainability in gastroenterology and digestive endoscopy: Position Paper from the Italian Association of Hospital Gastroenterologists and Digestive Endoscopists (AIGO).

Climate crisis is dramatically changing life on earth. Environmental sustainability and waste management are rapidly gaining centrality in quality improvement strategies of healthcare, especially in procedure-dominant fields such as gastroenterology and digestive endoscopy. Therefore, healthcare interventions and endoscopic procedures must be evaluated through the 'triple bottom line' of financial, social, and environmental impact.

Correct use of telemedicine in gastroenterology, hepatology, and endoscopy during and after the COVID-19 pandemic: Recommendations from the Italian association of hospital gastroenterologists and endoscopists (AIGO).

The purpose of the present document is to provide detailed information on the correct and optimal use of digital media to ensure continuity of care for gastroenterological patients in everyday clinical practice, in health emergencies and/or when the patient cannot reach the hospital for other reasons. During the recent COVID-19 pandemic, telemedicine has allowed many patients with chronic diseases to access remote care worldwide, proving to be the ideal solution to overcome restrictions and carry out non-urgent routine follow-ups on chronic patients. The COVID-19 pandemic has therefore made organizational and cultural renewal essential for the reorganization of healthcare in order to ensure greater continuity of care with a minimum risk of spreading the virus to users, practitioners and their families.

Linked-color imaging versus white-light colonoscopy in an organized colorectal cancer screening program.

Background And Aims: Linked-color imaging (LCI), a new image-enhancing technology emphasizing contrast in mucosal color, has been demonstrated to substantially reduce polyp miss rate as compared with standard white-light imaging (WLI) in tandem colonoscopy studies. Whether LCI increases adenoma detection rate (ADR) remains unclear.

Methods: Consecutive subjects undergoing screening colonoscopy after fecal immunochemical test (FIT) positivity were 1:1 randomized to undergo colonoscopy with LCI or WLI, both in high-definition systems.

Clean Colon Software Program (CCSP), Proposal of a standardized Method to quantify Colon Cleansing During Colonoscopy: Preliminary Results.

Background And Study Aims: Neoplastic lesions can be missed during colonoscopy, especially when cleansing is inadequate. Bowel preparation scales have significant limitations and no objective and standardized method currently exists to establish colon cleanliness during colonoscopy. The aims of our study are to create a software algorithm that is able to analyze bowel cleansing during colonoscopies and to compare it to a validate bowel preparation scale.

Barrett's esophagus and adenocarcinoma risk: the experience of the North-Eastern Italian Registry (EBRA).

Objective: To establish the incidence and risk factors for progression to high-grade intraepithelial neoplasia (HG-IEN) or Barrett's esophageal adenocarcinoma (BAc) in a prospective cohort of patients with esophageal intestinal metaplasia [(BE)].

Background: BE is associated with an increased risk of BAc unless cases are detected early by surveillance. No consistent data are available on the prevalence of BE-related cancer, the ideal surveillance schedule, or the risk factors for cancer.

People's attitude toward xenotransplantation: affective reactions and the influence of the evaluation context.

Background: One of the major issues in transplantation is to find a strategy to overcome the scarcity of human organs. One of the interventions under investigation is represented by xenotransplantation. The present study aimed to understand the role of psychological factors on people's perception of xenotransplantation.

Strengthening acceptance for xenotransplantation: the case of attraction effect.

Background: Despite being still at the experimental level, xenotransplantation may become an effective strategy to overcome the scarcity of human organs. However, at the present time there is considerable resistance to this kind of biomedical technology. The aim of the present study was to identify novel strategies to reduce patients' negative affective reactions towards xenotransplantation helping them to understand the advantages of xenotransplantation in a more analytical fashion and increase their acceptance for this approach.

Torque Teno Virus: any pathological role in liver transplanted patients?

Few studies have been performed on the prevalence of Torque Teno Virus (TTV) infection in liver transplant (LT) recipients. The aim of this study was to assess the prevalence, viremia and genogroup pattern of TTV among LT patients and to ascertain whether TTV causes liver damage in liver transplanted patients with biochemical and histological changes of unknown origin. Twenty-five patients were evaluated before and after LT; 80 healthy subjects were considered as controls.

Influence of steroids on HCV recurrence after liver transplantation: A prospective study.

Background/aims: To assess the effect of long-term maintenance of steroids on HCV recurrence after liver transplantation (LT), that is still controversial, a prospective multicentre trial was conducted at the centres of Bologna and Padua, Italy.

Methods: From September 2002, 47 eligible HCV positive LT recipients were randomized to receive 2 different steroid schedules in association with tacrolimus: group A: rapid tapering and withdrawal 91 days after LT group B: slow tapering and withdrawal 25 months after LT. Thirty-nine patients were assessable: 23 in group A and 16 in group B.

Occurrence of post-transplant lymphoproliferative disorders among over thousand adult recipients: any role for hepatitis C infection?

Background: Post-transplant lymphoproliferative disorders represent an increasingly important complication of organ transplantation. Although the majority of the post-transplant lymphoproliferative disorder are etiologically related to Epstein-Barr virus infection other factors may play a role. Hepatitis C virus may induce clonal expansion of B-lymphocytes and has been associated with extrahepatic lymphoproliferative disorders.

Understanding of and attitudes to organ donation and transplantation: a survey among Italian university students.

Background: Students have a positive attitude to organ donation and transplantation, usually associated with their personal willingness to donate their organs after death. The aim of this study was to evaluate the opinions of university students on transplantation and organ donation, at a single Italian university.

Methods: University undergraduates attending the first year on five different courses in 2001 were surveyed at Padua University by using an anonymous 13-item questionnaire.

Understanding of and attitude to xenotransplantation among Italian university students: impact of a 3-yr university course.

Background: Young people, and students in particular, generally have a positive attitude to xenotransplantation. We reported previously that university students attending their first year approved of the idea of transplanting animal organs into humans. The aim of this study was to evaluate the impact of a 3-yr course at various faculties on the university students' understanding of and attitude to xenotransplantation.

Different neurological outcome of liver transplantation for Wilson's disease in two homozygotic twins.

Wilson's disease is a genetic disorder characterized by accumulation of copper in many organs and tissues. Phenotypic manifestations are wide-ranging from neuropsychiatric disorders, to severe liver disease requiring liver transplantation. Clinical presentation is not often related to the genetic defect and siblings may have different type of disease.

Understanding of and attitudes to xenotransplantation: a survey among Italian university students.

Unlabelled: Xenotransplantation is currently at the experimental stages on animal models and many problems still have to be overcome in the biomedical, immunological and ethical fields. Moreover, people's attitudes to xenotransplantation vary: surveys among intensive-care staff have revealed negative opinions, while the general public and students seem to be more positive. Little is known about the influence of schooling and the choice of university faculty on attitudes to xenotransplantation.
