Potential Dutch elm disease vector beetle species were caught with pheromone bottle traps and handpicked in 2019: in total, seven species and 261 specimens were collected. The most common was , but by percent, the incidence of was highest in , followed by and . We analysed the beetles DNA using PacBio sequencing to determine vector beetles of . was found on six out of seven analysed beetle species: , S, , , and . The last two beetles were detected as vectors for for the first time. Previous knowledge on the spread of beetles is discussed.

Outbreaks of COVID-19 in humans, Dutch elm disease in forests, and highly pathogenic avian influenza in wild birds and poultry highlight the disruptive impacts of infectious diseases on public health, ecosystems and economies. Infectious disease dynamics often depend on environmental conditions that drive occurrence, transmission and outbreaks. Remote sensing can contribute to infectious disease research and management by providing standardized environmental data across broad spatial and temporal extents, often at no cost to the user.

Elm () species are important components of forest resources with significant ecological and economic value. As tall hardwood trees that are drought-resistant, poor-soil-tolerant, and highly adaptable, species are an excellent choice for ecologically protected forests and urban landscaping. Additionally, the bioactive substances identified in the fruits, leaves, bark, and roots of have potential applications in the food and medical fields and as raw materials in industrial and cosmetic applications.

American elm (), highly prized for its ornamental value, has suffered two successive outbreaks of Dutch elm disease (DED) caused by ascomycete fungi belonging to the genus . To identify the genes linked to the pathogenicity of different species and lineages of , we inoculated 2-year-old saplings with six strains representing three species of DED fungi, and one strain of the saprotroph . Differential expression analyses were performed following RNA sequencing of fungal transcripts recovered at 3- and 10-days post-infection.

Background: The safety and efficacy of oral anticoagulation for prevention of major adverse cardiovascular events in people with atrial fibrillation and spontaneous intracranial haemorrhage are uncertain. We planned to estimate the effects of starting versus avoiding oral anticoagulation in people with spontaneous intracranial haemorrhage and atrial fibrillation.
Methods: In this prospective meta-analysis, we searched bibliographic databases and trial registries using the strategies of a Cochrane systematic review (CD012144) on June 23, 2023.

Dutch elm disease (DED) is a vascular wilt disease caused by the pathogens and with multiple ecological phases including pathogenic (xylem), saprotrophic (bark) and vector (beetle flight and beetle feeding wound) phases. Due to the two DED pandemics during the twentieth century the use of elms in landscape and forest restoration has declined significantly. However new initiatives for elm breeding and restoration are now underway in Europe and North America.
