The global spread of Aedes albopictus raises growing public health concerns due to its role in transmitting dengue, chikungunya, and Zika. In southern France, the increase in imported dengue cases and local transmission underlines the urgent need for effective vector control. While efforts primarily target private breeding sites, public spaces also contribute notably to larvae presence. Understanding the impact of urban landscapes on the distribution of breeding sites is crucial for optimizing vector control strategies, identifying high-risk areas, and reducing mosquito populations. This study aims to investigate how urban landscapes impact the distribution of Ae. albopictus larvae in public spaces, with a focus on storm drains and telecom cable chambers in Montpellier, France. Very high-resolution satellite imagery was used to characterize urban landscapes through textural analyses of spectral indices. Environmental bias was assessed by analyzing the representativity of sampled breeding sites within the diverse urban landscapes. Species distribution models (SDMs) were built, their predictive accuracy was evaluated, and an ensemble model was created to predict larval presence across the study area. SDMs predicted a high probability of larval presence in the western and northeastern parts of Montpellier, with low uncertainty. The most influential variables for predicting larval presence were the mean of Normalized Difference Vegetation Index (NDVI), texture indices from both NDVI, brightness index (BI), and the panchromatic image. Urban vegetation significantly influences larval presence, although higher vegetation index values correlate with a decreased probability of larval occurrence. Additionally, the combination of vegetation and urban structures plays a crucial role in determining the presence of Ae. albopictus larvae in public spaces, where small, organized urban objects and large patches of vegetation increase the likelihood of larval presence. This study highlights the potential of very high-resolution remote sensing and species distribution modeling for enhancing urban mosquito control strategies, ultimately contributing to improved public health policies outcomes in the face of vector-borne disease threats.Despite having more medical and social vulnerabilities than men with substance use disorder (SUD), women with SUD are underrepresented in addiction healthcare structures. This is because they experience double stigma—from society (including the medical community) and from themselves—which hinders them from accessing healthcare.
Using a mixed-methods approach, the main objective of the Calliope study is to explore and compare healthcare satisfaction among women with SUD according to the category of healthcare structure they attend: specialised addiction centres versus primary care centres called ‘microstructures’. A total of 240 women receiving care for SUD will be included in the study, with equal representation from specialised addiction centres and ‘microstructures’. All participants will complete a standardised questionnaire to collect quantitative data. Additionally, a subsample of 40 women will be selected to participate in in-depth, semistructured interviews to gather qualitative data. Additionally, focus groups will be conducted with healthcare professionals to explore their perspectives and practices.
Calliope was reviewed and approved by the institutional ethics committee of Paris Cité University (IRB: 00012024–02). The study’s findings will provide a greater understanding of the characteristics, needs and satisfaction with healthcare of women with SUD living in France. Moreover, they will help guide the development of tailored therapeutic interventions for this population.
The objectives of this study were to determine the prevalence of burnout risk and intention-to-leave among intensive care unit (ICU) nurses and analyse the association of these with workload and work environment.
A cross-sectional survey of nurses working in ICUs was conducted in France between 15 January 2024 and 15 April 2024 alongside a longitudinal assessment of workload during the same period.
ICU nurse workload was assessed using the Nursing Activities Score (NAS). The risk of burnout was assessed using the Maslach Burnout Inventory scale and intention-to-leave the hospital was assessed with a binary question. A total of 1271 nurses working in 61 intensive care units completed the questionnaire and 14,134 NAS per patient and 1885 NAS per nurse were included in the study.
The median overall of burnout by hospital site was 64.7% [P25: 53.3–P75: 72.7] for the broad definition and a median of 20.7% [13.3–27.3] of ICU nurses reported an intent-to-leave their job. The median overall NAS score per nurse was 135.9% [121.4–156.9] and the prevalence of NAS scores exceeding 100% per nurse was 73.9% [62.8–80.3]. A significant association was found between nurses working in an ICU with a better work environment and all dimensions of burnout as well as the intention-to-leave the job. A prevalence in the hospital site of NAS scores exceeding 100% per nurse below the median was associated with a lower burnout (OR = 0.69, 95% CI: 0.50–0.88 for broad definition) and intention-to-leave the job (OR = 0.68, 95% CI: 0.50–0.92).
This study found significant associations between burnout and the intention to leave the job for nurses in ICUs, mainly due to a better work environment and, to a lesser extent, a lower workload for nurses.
In an era of nurse shortages and absenteeism, it is crucial for institutions to retain their nursing staff. Our results should encourage hospital managers to take action to improve the ICU work environment and keep ICU workloads manageable to decrease burnout and the intention-to-leave the job among ICU nurses.
