Aneurysmal or occlusive abdominal aortic pathology has seen its prevalence increase over the years despite the various cardiovascular risk factor management campaigns deployed.
Currently, a large proportion of these aortic pathologies require effective and definitive treatment by open surgery. In fact, minimally invasive endovascular treatment, which can provide good results in certain cases, cannot be generalized simply and can even lead to sometimes incomplete treatments requiring even more complex secondary open surgery.
The preoperative assessment before open aortic surgery is relatively well coded with cardiological and respiratory assessments in particular. However, the literature has so far never focused on the overall vision of the patient with a complete functional assessment which would make it possible to consider a specific preoperative fragility scale and would thus give practitioners corrective targets before such an intervention. in order to simplify the patient's post-operative journey by limiting complications.
The investigators therefore propose to collect a certain number of elements already collected in standard care in a systematic and prospective manner in order to create a risk scale. All of these elements being modifiable, they should ultimately make patients more robust for such an intervention.

Following tooth extraction, volumetric changes in the soft and hard tissues of the extraction site are expected to occur with considerable resorption of the alveolar bone in both the vertical and the horizontal dimensions. These changes may complicate surgical implant placement and may also compromise the outcome of the prosthetic reconstruction. Various treatment approaches have been introduced aiming to preserve the dimensions of the alveolar ridge at the extraction site and facilitate optimal implant placement.
This prospective randomized controlled trial aims to determine the efficacy of alveolar ridge preservation utilizing two different socket seal approaches compared to spontaneous healing to stabilize the blood clot within the postextraction socket. Thirty-six subjects will be randomly allocated into one of the three treatment groups. Group-A: Extraction of the tooth and suturing of the extraction socket with resorbable suture PGA 5/0. Group-B: Extraction of the tooth and placement of a Free Gingival Graft stabilized with resorbable suture PGA 5/0. Group-C: Extraction of the tooth and placement of the Polylactic-Glycolic Acid membrane stabilized with resorbable suture PGA 5/0. After the initial examination for screening, subjects will be assessed at baseline-extraction day- and after 1, 2, and 6 weeks, and 3 months. The changes of the alveolar crest will be determined in height and width, in addition to volumetric changes in the soft tissues, and the width of keratinized tissues. The wound healing process will be visually assessed.

The EVAPREF project aims to increase access to fertility preservation by developing an approach to improve and evaluate existing information and coordination tools developed by the Pays-de-la-Loire and Occitanie Regional Cancer networks. First, the investigators will use a qualitative, iterative, user-centered and participatory approach to improve the current tools and create training content for the physicians who will use these tools. Second, the investigators will conduct a randomized stepped wedge trial of women under 40 newly treated with chemotherapy for breast cancer. The investigators will evaluate the rate of fertility preservation consultation before and after implementation of the improved tools, over a 30-month period from mid-2023 to the end of 2025. Finally, in a third step, the investigators will study their approach (context-sensitive implementation analysis) and provide key elements for its transferability to other contexts and in particular to other Regional Cancer networks in France.
