    Abstract With the dramatic background of a newly emerged virus (SARS-CoV-2) spreading around the world, Coronavirus and other infectious health threats for the human and animal populations were illustrated and debated in excellent presentations at the IABS meeting 26-28 of February 2020. Historical evidence of pandemics and lessons learned from recent epidemics or epizootics caused by many pathogens (e.g., Ebola, Zika, and African Swine Fever viruses) illustrated the overarching need for close international cooperation. New and old technologies in vaccine development and their use were presented, resulting in a call for greater interaction between the human and the veterinary fields in order to leverage the expertise and knowledge in both human and animal medicine. The One Health concept was also emphasized for eliminating the 59,000 fatal human rabies cases annually attributed to unvaccinated dogs. For preventable, infectious diseases commonly spreading in the poorer regions of the world, a new regulatory approach and governance structure was called for to give access to affordable vaccines. Vaccines were touted as one of the most successful health invention ever introduced; on a similar level to health improvements due to clean water.

    Abstract Endothelin-1 (ET-1) overactivity has been implicated as a factor contributing to glaucomatous neuropathy, and it has been utilized in animal models of retinal ischemia. The functional effects of long-term ET-1 exposure and possible compensatory mechanisms have, however, not been investigated. This was therefore the purpose of our study. ET-1 was delivered into rat eyes via a single intravitreal injection of 500 µM or via transgene delivery using an adeno-associated viral (AAV) vector. Retinal function was assessed using electroretinography (ERG) and the retinal expression of potentially compensatory genes was evaluated by means of qRT-PCR. Acute ET-1 delivery led to vasoconstriction and a significant reduction in the ERG response. AAV-ET-1 resulted in substantial transgene expression and ERG results similar to the acute ET-1 injections and comparable to other models of retinal ischemia. Compensatory changes were observed, including an increase in calcitonin gene-related peptide (CGRP) gene expression, which may both counterbalance the vasoconstrictive effects of ET-1 and provide neuroprotection. This chronic ET-1 ischemia model might be especially relevant to glaucoma research, mimicking the mild and repeated ischemic events in patients with long-term vascular dysfunction. The compensatory mechanisms, and particularly the role of vasodilatory CGRP in mitigating the retinal damage, warrant further investigation with the aim of evaluating new therapeutic strategies.

    Abstract Drug discovery in epilepsy began with the finding of potassium bromide by Sir Charles Locock in 1857. The following century witnessed the introduction of phenotypic screening tests for discovering antiseizure medications (ASMs). Despite the high success rate of developing ASMs, they have so far failed in eliminating drug resistance and in delivering disease-modifying treatments. This emphasizes the need for new drug discovery strategies in epilepsy. RNA-based drugs have recently shown promise as a new modality with the potential of providing disease modification and counteracting drug resistance in epilepsy. RNA therapeutics can be directed either toward noncoding RNAs, such as microRNAs, long noncoding RNAs (ncRNAs), and circular RNAs, or toward messenger RNAs. The former show promise in sporadic, nongenetic epilepsies, as interference with ncRNAs allows for modulation of entire disease pathways, whereas the latter seem more promising in monogenic childhood epilepsies. Here, we describe therapeutic strategies for modulating disease-associated RNA molecules and highlight the potential of RNA therapeutics for the treatment of different patient populations such as sporadic, drug-resistant epilepsy, and childhood monogenic epilepsies.

    Abstract On the 17th of October 2019, a workshop was held at Wageningen Bioveterinary Research in Lelystad, the Netherlands, to discuss the obstacles to vaccination in the veterinary field. Participants from academia, OIE, FAO, EC, EMA, USDA, national regulatory and veterinary health authorities, and the animal health industry discussed how availability and access to animal vaccines can be improved not just in the EU and US but also in Low to Middle Income Countries (LMIC) across the world and agreed that this requires innovations in both the scientific and the regulatory field. The workshop called for engaging all stakeholders to improve regulatory acceptance of novel vaccine technologies and encourage their registration. There is a need for better mutual understanding between academia, industry and regulators, and more openness to discuss framework, requirements, and product authorisations, and to converge the regulatory rules between regions. The next leap forward could be a broader application of novel technologies using RNA- or DNA-based vaccine platforms, where the "backbone" is maintained, while the gene of interest coding for an immunogenic protein can be exchanged in a standardised manner. This approach enables rapid response in outbreak situations and should lower the risk and cost of vaccine development.

    Abstract Objectives: Subarachnoid haemorrhage (SAH) carries a high burden of morbidity and mortality. One in three patients develop vasospasm, which is associated with Delayed Cerebral Ischemia. The pathophysiology includes vasoconstrictor receptor upregulation in cerebral arteries. The protein kinase C - inhibitor RO-31-7549 reduces the expression of several vasoconstrictor receptors and normalizes cerebral blood flow in experimental SAH but functional and behavioural effects are unknown. This study was undertaken to analyse functional outcomes up to 14 days after experimental SAH.
    Materials and methods: 54 male rats were randomised to experimental SAH or sham, using the pre-chiasmatic, single injection model, and subsequent treatment or vehicle. 42 remained for final analysis. The animals were euthanized on day 14 or when reaching a humane endpoint. The primary endpoint was overall survival, defined as either spontaneous mortality or when reaching a predefined humane endpoint. The secondary outcomes were differences in the rotating pole test, weight, open field test, novel object recognition and qPCR of selected inflammatory markers.
    Results: In the vehicle group 6/15 rats reached the humane endpoint of >20% weight loss compared to 1/14 in the treatment group. This resulted in a significant reduced risk of early euthanasia due to >20% weight loss of HR 0.15 (0.03-0.66, p = 0.04). Furthermore, the treatment group did significantly better on the rotating pole test, RR 0.64 (0.47-0.91, p = 0.02).
    Conclusion: RO-31-7549 improved outcomes in terms >20% weight loss and rotating pole performance after experimental SAH and could be investigated.

    Abstract Importance: Since bilateral simultaneous postoperative endophthalmitis (BSPOE) after immediate sequential bilateral cataract surgery (ISBCS) can be devastating for the patient, evaluating such cases in depth is important to maintaining patient safety.
    Objective: To evaluate whether a systemic breach of sterility was associated with an outbreak of BSPOE after ISBCSs performed on the same day at a single community-based eye clinic.
    Design, setting, and participants: This retrospective case series included all patients diagnosed with BSPOE at ophthalmology departments in Denmark following an infectious outbreak after ISBCSs performed at a single community-based eye clinic in December 2022.
    Exposure: Bilateral simultaneous postoperative endophthalmitis acquired after ISBCS.
    Main outcome and measures: Patient recovery from BSPOE after ISBCS was evaluated based on clinical and microbiological reports.
    Results: A woman aged 71 years, a man aged 84 years, and a woman aged 79 years consecutively presented with symptoms of endophthalmitis at regional eye departments 4 to 8 days after ISBCS performed on the same date at the same eye clinic. Five of 6 infected eyes underwent vitrectomy, and all eyes received an intravitreous injection of antibiotics. The same strain of Staphylococcus epidermidis was isolated in 4 of 5 eyes that underwent vitrectomy. Contamination of viscoelastics was ruled out with repeated cultures. One eye was eviscerated due to phthisis. In another patient, the final visual acuity of the eye most severely affected was 20/63 Snellen equivalents. Visual acuity of the remaining eyes recovered to 20/25 (3 eyes in 2 patients) and 20/20 (1 eye) Snellen equivalents.
    Conclusions and relevance: The finding of the same strain of S epidermidis in all patient cultures suggests a systemic breach of sterility at the clinic on the day of ISBCS. The outcome of these cases emphasizes the need to adhere to a strict surgical methodology and sterile principles during ISBCS.

    Abstract Small interfering RNA (siRNA)-based therapeutics holds the promise to treat a wide range of human diseases that are currently incurable using conventional therapies. Most siRNA therapeutic efforts to date have focused on the treatment of liver diseases due to major breakthroughs in the development of efficient strategies for delivering siRNA drugs to the liver. Indeed, the development of lipid nanoparticle-formulated and GalNAc-conjugated siRNA therapeutics has resulted in recent FDA approvals of the first siRNA-based drugs, patisiran for the treatment of hereditary transthyretin amyloidosis and givosiran for the treatment of acute hepatic porphyria, respectively. Here, we describe the current strategies for delivering siRNA drugs to the liver and summarize recent advances in clinical development of siRNA therapeutics for the treatment of liver diseases.
