La donnée d'un 9î-morphisme (resp. d'un Ri-morphisme) V-^W se traduit par celle d'un 9î-morphisme...

This research focuses on the perception of patients who participated in Continuous Quality Improvement Committees (CIC) regarding their contribution, lessons learned, and challenges encountered. The committees are engaged in a care partnership approach where patients are recognized for their experiential knowledge and treated as full members of the clinical team. Based on patient interviews, we conclude tha experience. They identify themselves as real partners in the care process and are grateful for the opportunity to improve the care provided to other patients by using their own experience and by brin relationship, particularly in terms of communication. They also become better acquainted with the complexity of the health system and its organization. However, their participation in CICs raised two challenges. The availability, as their professional schedules did not always allow them to participate in meetings. The second was their frustration with the slow decision-making process and implementation of necessary measures for quality improvement of healthcare and services. This study highlights the contribution of successful patient participation to quality of care improvement.

Let A be a non-isotrivial almost ordinary Abelian surface with possibly bad reductions over a global function field of odd characteristic p. Suppose ∆ is an infinite set of positive integers, such that m p = 1 for ∀m ∈ ∆. If A doesn't admit any global real multiplication, we prove the existence of infinitely many places modulo which the reduction of A has endomorphism ring containing Z[x]/(x 2 − m) for some m ∈ ∆. This generalizes the S-integrality conjecture for elliptic curves over number fields, as proved in [BIR08], to the setting of Abelian surfaces over global function fields. As a corollary, we show that there are infinitely many places modulo which A is not simple, generalizing the main result of [MST20] to the non-ordinary case.
