Article Synopsis
- This study aimed to evaluate the types of heart failure events (primary vs. secondary) in patients with severe heart failure and their impact on 2-year mortality rates.
- Researchers included 304 patients and categorized heart failure events into non-triggered (primary) and triggered (secondary) decompensations during a 24-month follow-up.
- Results showed that primary decompensations were three times more common than secondary ones, but both types significantly increased the risk of death compared to patients without any heart failure events.
Objectives: Quantify the effects of characteristics of nursing homes and their surroundings on the spread of COVID-19 outbreaks and assess the changes in resident protection between the first 2 waves (March 1 to July 31 and August 1 to December 31, 2020).
Design: An observational study was carried out on data on COVID-19 outbreaks extracted from a database that monitored the spread of the virus in nursing homes.
Setting And Participants: The study concerned all 937 nursing homes with >10 beds in Auvergne-Rhône-Alpes region, France.
Missing data may lead to bias and loss of information in epidemiological research. In this article, we propose an approach to analyze missing data on comorbidity variables in a register with consideration of the territorialized organization of the collection. To illustrate this approach, we used the national REIN registry as an application case.

- The study explores the ability of human ovarian cortex cells to thrive in unconventional culture conditions using chitosan hydrogel micro-bioreactors compared to traditional wells.
- Results showed that follicle growth was generally better in bioreactor cultures over 90 days, with more intact and growing follicles compared to control cultures.
- The findings suggest that bioreactor environments may enhance follicle preservation and could be beneficial for future toxicological studies.
Background: Differences in procedural success rates have been proposed to explain the divergent results between the MITRA-FR trial (Percutaneous Repair with the MitraClip Device for Severe Functional/Secondary Mitral Regurgitation) and the COAPT trial (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients with Functional Mitral Regurgitation).
Aim: To examine whether MITRA-FR patients who had successful clip implantation achieved a better outcome than the control group.
Methods: Based on the per protocol population of MITRA-FR, we compared the outcome in 71 patients in whom optimal clip implantation was achieved (group 1: mitral regurgitation grade ≤ 1 + at discharge) with that in 23 patients with non-optimal clip implantation (group 2: mitral regurgitation grade ≥ 2 + at discharge) and that in 137 patients in the control group (group 3).
