Hospital Universitario La Fe

The environmental impact of healthcare practice in the context of climate change is in the spotlight. Digestive endoscopy units are the third hospital unit that generates the most waste and environmental impact. For this reason, scientific societies advice studying and adopting more sustainable clinical practices, reconsidering current protocols for reprocessing and disinfection of single-use material. One of the devices, widely used and which generates a large amount of waste, is the polyp trap. It allows an easy recovery of the polyps removed during endoscopy. This device is discarded after a single use in some centers, and reused after washing and disinfection in others. Manufacturers recommend the single-use of the device, even there is no scientific evidence to support this action. In the investigators endoscopy unit, 3800 polyp traps are used yearly. The investigators hypothesis is that reusing the polyp catcher has similar safety to disposal after a single use, with better environmental and economic results. Objectives: To evaluate the safety of the reused and discarded after a single-use polyp trap. The investigators will assess 1) the post-colonoscopy infection rate and 2) the reliability of the anatomopathological study, 3) CO2 emissions and 4) costs of each practice. Methodology: A non-inferiority study will be carried out by observing the usual clinical practice of different centers and collecting data that suggest infection, cross-sampling and general complications. The results will be easily applicable in endoscopy units and will serve as a basis for future studies with other more controversial devices.

This is a multicenter, randomized, open-label, pragmatic low intervention clinical trial comparing high intensity reinduction chemotherapy with low intensity therapies in 1st or 2nd relapse Acute Myeloid Leukemia. The study is funded by European Commission (HORIZON-MISS-2022-CANCER-01-03, Project ID 101104421)

Intro:
The present clinical research protocol is part of the LEOPARD European project (Grant n° 101080964 Horizon Europe) which aims to design and validate new predictive models of mortality among liver transplantation (LT) candidates.
MELD based-liver graft allocation systems have become increasingly inaccurate over the last decade to predict mortality/dropout of liver transplantation (LT) candidates on the waitlist (WL). Wide disparities in mortality/dropout on the WL also exist across European countries, ranging from 5 to 30% according to transplantation indications. In this setting, the European Commission- Horizon Europe funded-LEOPARD project intends to design new, 2nd generation, AI-machine learning-based predictive models of delisting in LT candidates, to better serve on time patients with the highest risk of dropout on the WL and to improve equity of access to LT across Europe.
Hypothesis/Objective The scientific justification of the LEOPARD PVC1 is therefore
1. to build an external cohort of LT candidates to test and validate the LEOPARD models, therefore providing robust evidence for adoption of LEOPARD models by Organ Sharing Organizations (OSOs).
2. to collect granular data, bio- and tissues sampes and images to test last-generation OMICs predictors and radiomics, therefore opening the door to design of 3rd generation, precision medicine-based predictive models.
The primary objective of the LEOPARD longitudinal study is to test and validate AI-based 2nd generation LEOPARD predictive models of mortality/drop out on the waitlist in patients with decompensated cirrhosis, or other end-stage chronic liver diseases, and in patients listed for HCC.
Method Multicenter Prospective longitudinal study in up to 630 enrolments (in case of replacing participants after inclusion) to obtain 600 patients meeting selection criteria, in 30 hospitals in 5 European countries including France, Italy, The Netherlands, Belgium and Germany.
