Introduction: Overcrowding in emergency departments (ED) is a major public health issue, leading to increased workload and exhaustion for the teams, resulting poor outcomes. It seems interesting to be able to predict the admissions of patients in the ED.
Aim: The main objective of this study was to build and test a prediction tool for ED admissions using artificial intelligence.
Methods: We performed a retrospective multicenter study in two French ED from January 1st, 2010 to December 31st, 2019.We tested several machine learning algorithms and compared the results.
Results: The arrival and departure times from the ED of 2 hospitals were collected from all consultations during the study period, then grouped into 87 600 one-hour slots. Through the development of two models (one for each location), we found that the XGBoost method with hyperparameter adaptations was the best, suggesting that the studied data could be predicted (mean absolute error) at 2.63 for Hospital 1 and 2.64 for Hospital 2).
Conclusions: This study ran the construction and validation of a powerful tool for predicting ED admissions in 2 French ED. This type of tool should be integrated into the overall organization of an ED, to optimize the resources of healthcare professionals.

Background: COVID-19 mRNA vaccines have demonstrated 95 % efficacy in the general population. However, their immunogenicity in adolescents with Type 1 Diabetes (T1D), who exhibit weaken immune responses, remains insufficiently explored.
Methods: Longitudinal analysis of innate immune responses following PRR-agonists and BNT162b2 vaccine stimulations, along with S-specific antibody responses, memory T cell recall responses, and RNA-sequencing were assessed in eight T1D adolescents and 16 healthy controls at six different timepoints.

Background: This study analyzed the epidemiological trends of three significant respiratory infectious diseases in Taiwan: invasive pneumococcal disease (IPD), influenza with severe complications, and tuberculosis during post-COVID-19 pandemic period.
Methods: We utilized data from Taiwan's Centers for Disease Control and Prevention (CDC) website and classified the COVID-19 prevention policies into three phases for the year 2021, 2022, and 2023. We then performed a statistical analysis of reported case numbers for the three respiratory diseases during the 3-year period using the Kruskal-Wallis test, followed by joinpoint regression model for the identification of seasonal distribution and variation.

Background: The optimal treatment of Osteochondral lesion of the talus (OLT) for subchondral bone cysts (SBCs) has not been finalized. The purpose of this systematic review and meta-analysis was to define whether OLT with small SBCs will affect the clinical outcomes of OLTs after arthroscopic microfracture.
Methods: We searched the Embase, Cochrane Library and PubMed databases up to May 13, 2024 for eligible comparative studies.

Introduction: Self-esteem and vocal perception are central aspects of identity and self-presentation, particularly within marginalized communities where voice and self-concept can be deeply intertwined with social acceptance and cultural dynamics. Among Brazilian gay men, generational differences in these areas may reflect broader social changes, shifts in stigma, and evolving notions of masculinity. This study aims to explore these differences, examining how self-esteem and self-assessed vocal descriptions vary across generations, thereby shedding light on specific needs and areas for potential support within these communities.
