Abstract	From 2020 up to summer 2023, there was a substantial change in the situation concerning the high pathogenic avian influenza (HPAI) virus in Europe. This change concerned mainly virus circulation within wildlife, both in wild birds and wild mammals. It involved the seasonality of HPAI detections, the species affected, excess mortality events, and the apparent increased level of contamination in wild birds. The knock-on effect concerned new impacts and challenges for the poultry sector, which is affected by repeated annual waves of HPAI arriving with wild migratory birds and by risks due to viral circulation within resident wild birds across the year. Indeed, exceeding expectations, new poultry sectors and production areas have been affected during the recent HPAI seasons in France. The HPAI virus strains involved also generate considerable concern about human health because of enhanced risks of species barrier crossing. In this article, we present these changes in detail, along with the required adjustment of prevention, control, and surveillance strategies, focusing specifically on the situation in France.

Abstract	Infectious bursal disease (IBD) is an avian viral disease caused in chickens by infectious bursal disease virus (IBDV). IBDV strains (Avibirnavirus genus, Birnaviridae family) exhibit different pathotypes, for which no molecular marker is available yet. The different pathotypes, ranging from sub-clinical to inducing immunosuppression and high mortality, are currently determined through a 10-day-long animal experiment designed to compare mortality and clinical score of the uncharacterized strain with references strains. Limits of this protocol lie within standardization and the extensive use of animal experimentation. The aim of this study was to establish a predictive model of viral pathotype based on a minimum number of early parameters measured during infection, allowing faster pathotyping of IBDV strains with improved ethics. We thus measured, at 2 and 4 days post-infection (dpi), the blood concentrations of various immune and coagulation related cells, the uricemia and the infectious viral load in the bursa of Fabricius of chicken infected under standardized conditions with a panel of viruses encompassing the different pathotypes of IBDV. Machine learning algorithms allowed establishing a predictive model of the pathotype based on early changes of the blood cell formula, whose accuracy reached 84.1%. Its accuracy to predict the attenuated and strictly immunosuppressive pathotypes was above 90%. The key parameters for this model were the blood concentrations of B cells, T cells, monocytes, granulocytes, thrombocytes and erythrocytes of infected chickens at 4 dpi. This predictive model could be a second option to traditional IBDV pathotyping that is faster, and more ethical.

Title translation	Day hospital in internal medicine: A chance for ambulatory care.
Abstract	Introduction: Internal medicine is an in-hospital speciality. Along with its expertise in rare diseases, it shares with general medicine the global care of patients but its place in the ambulatory shift has yet to be defined. The objective of our work was to evaluate the benefits of an internal medicine day-hospital devoted to general medicine. Methods: Named "Centre Vi'TAL" to underline the link between the city and the hospital, this novel activity was implemented in order to respond quickly to general practitioners having difficulties to synthesize their complex patients or facing diagnostic or therapeutic problems. Using preferentially email for communication, the general practitioners can contact an internist who is committed to respond on the same day and take over the patient within 7 days if day-hospital is appropriate for his condition. The other patients are directed either to the emergency department, consultation or full hospitalization. Results: In 14 months, the center has received 213 (144 women, 69 men) patients, mean age 53.6, addressed by 88 general practitioners for 282 day-hospital sessions. Requests included problem diagnoses (n=105), synthesis reviews for complex patients (n=65), and treatment (n=43). Conclusion: In the ambulatory shift advocated by the authorities, this experience shows that internal medicine should engage in the recognition of day-hospital as a place for diagnosis and synthesis reviews connected with the city while leaving the general practitioners coordinator of their patient care. This activity of synthesis in day-hospital is useful for the patients and efficient for our healthcare system.

Abstract	Currently, turkey coronaviruses (TCoV) are isolated from homogenized intestines of experimentally infected embryos to ensure a maximum recovery of viral particles from all components of the intestines. However, the process of homogenization also ensures release of a significant amount of cellular RNAs into the sample that hinders downstream viral genome sequencing. This is especially the case for next generation sequencing (NGS) which sequences molecules at random. This characteristic means that the heavily abundant cellular RNA in the sample drowns out the minority viral RNA during the sequencing process and, consequently, very little to no viral genome data are obtained. To address this problem, a method was developed, in which 10 descendent isolates of the European strain of TCoV were recovered uniquely from the intestinal lumen without homogenization of the tissue. For nine out of 10 samples, NGS produced viral RNA reads with good coverage depth over the entire TCoV genomes. This is a much-needed new, simple and cost effective method of isolating TCoV that facilitates downstream NGS of viral RNA and should be considered as an alternative method for isolating other avian enteric coronaviruses in the interest of obtaining full-length genome sequences.

Title translation	Analysis of anorectal manometry data in central and peripheral neurological deseases: Review of the literature.
Abstract	Introduction: Peripheral or central neurological deseases are providers of anorectal disorders of variable clinical expression (constipation, dyschezia, faecal incontinence (FI)…). Anorectal manometry (ARM) participates in their exploration to determine the underlying mechanisms, guide and optimize treatments. The objective of this work was to determine if there is a pattern of ARM data in neurological populations. Materials et methods: Literature review from PubMed, Cochrane and Google scholar databases, using the following keywords: parkinsonian disorders; parkinson's disease; multiple slcerosis; neurolog; spinal cord injury; spina bifida occulta; stroke; pudendal; endometriosis; peripheral nervous system diseases. 196 articles were isolated and finally 45 retained after reading the title and the abstract. Results:* Data comparison was difficult due to the heterogeneity of techniques and thresholds used. In central lesions, resting and squeeze anal pressures were often altered. The presence of FI or constipation, the sex and the lesion level were factors influencing these data (low if complete injury, women or EDSS>5.5). In case of peripheral lesion, it is the anal tone and the contraction that varied the symptomatology. The sensory thresholds were variable regardless of the impairment. Conclusion: This review did not identify a data pattern of ARM in central and peripheral neurological deseases. Gradual standardization of techniques and protocols will allow better comparison of data.

Title translation	Animal circoviruses and associated diseases.
Abstract	Animal circoviruses belong to the Circovirus genus of the Circoviridae family. Nowadays, only swine and birds were identified as circovirus hosts. Circoviruses have a single-stranded circular genome of approximately 2000 nucleotide long. DNA of these viruses possesses : (i) a nonanucleotide sequence essential for replication, flanked by inverted repeat sequences, a palindrome that has the potential to form a stem-loop structure and (ii) two major ORFs, located on the viral and complementary strands, which encode respectively the replication-associated protein (Rep) and the capsid protein (Cap). All the circoviruses described at the present time, except porcine circovirus of type 1, are associated with immunosuppressive or immunodepressive diseases. Histopathological lesions such as cytoplasmic inclusions of virus in histiocytic cells and T and B lymphocyte depletion in lymphoid organs, are commonly noticed. No medical prophylaxis of circovirus infections is currently available.

Abstract	Avian influenza virus (AIV) outbreaks occur frequently worldwide, causing a potential public health risk and great economic losses to poultry industries. Considering the high mutation rate and frequent genetic reassortment between segments in the genome of AIVs, emerging new strains are a real threat that may infect and spread through the human population, causing a pandemic. Therefore, rapid AIV diagnostic tests are essential tools for surveillance and assessing virus spreading. Real-time reverse transcription PCR (rRT-PCR), targeting the matrix gene, is the main official standard test for AIV detection, but the method requires well-equipped laboratories. Reverse transcription Loop-Mediated Isothermal Amplification (RT-LAMP) has been reported as a rapid method and an alternative to PCR in pathogen detection. The high mutation rate in the AIV genome increases the risk of false negative in nucleic acid amplification methods for detection, such as PCR and LAMP, due to possible mismatched priming. In this study, we analyzed 800 matrix gene sequences of newly isolated AIV in the EU and designed a highly efficient LAMP primer set that covers all AIV subtypes. The designed LAMP primer set was optimized in real-time RT-LAMP (rRT-LAMP) assay. The rRT-LAMP assay detected AIV samples belonging to nine various subtypes with the specificity and sensitivity comparable to the official standard rRT-PCR assay. Further, a two-color visual detection RT-LAMP assay protocol was adapted with the aim to develop on-site diagnostic tests. The on-site testing successfully detected spiked AIV in birds oropharyngeal and cloacal swabs samples at a concentration as low as 10
