We aimed to assess the mental health of adults living in Ukraine one year after onset of the Russo-Ukrainian war, along with quality of life and coping strategies. Quota sampling was used to collect online survey data from 2364 adults aged 18-79 years living in Ukraine from April 5, 2023 to May 15, 2023. Among adults living in Ukraine, 14.4 % had probable post-traumatic stress disorder (PTSD), another 8.9 % had complex PTSD (CPTSD), 44.2 % had probable depressive disorder, 23.1 % had anxiety disorder and 38.6 % showed significant loneliness. In adjusted models, the number of trauma events experienced during the war showed a dose-response association with PTSD/CPTSD and was associated with depressive disorder and anxiety disorder. Quality of life domains, particularly physical quality of life, were negatively associated with PTSD/CPTSD, depressive disorder, anxiety disorder, and number of trauma events. Maladaptive coping was positively associated with depressive disorder, anxiety disorder, PTSD/CPTSD and loneliness. All quality of life domains were positively associated with using adaptive coping strategies. Mental health disorders are highly prevalent in adults living in Ukraine one year into the war. Policy and services can promote adaptive coping strategies to improve mental health and quality of life for increased resilience during war.

Here, we report the complete genome sequence of an African swine fever (ASF) virus (ASFV/Kyiv/2016/131) isolated from the spleen of a domestic pig in Ukraine with a lethal case of African swine fever. Using only long-read Nanopore sequences, we assembled a full-length genome of 191,911 base pairs in a single contig.

Staphylococci have a wide range of pathogenic properties, among which stands increased resistance to antibiotics and the ability to form a biofilm. Being divided into coagulase-positive and coagulase-negative, they have different and, at the same time, common biological properties and may be a source of genetic material for each other. The aim of the study was to examine the properties of staphylococci, isolated from various objects (milk, pigs, companion animals, humans), their resistance to antibiotics, the ability to form a biofilm and the presence of genes, responsible for resistance to methicillin and biofilm formation. In this study we used 89 Staphylococci strains. 18 (20.2 %) strains were coagulase-positive, where 2 (2.2 %) strains, isolated from different animals and humans, had a complete set of phenotypic (plasma coagulation, biofilm formation, resistance to oxacillin and benzylpenicillin) and genotypic (mec A, fem B, ica A, ica D) signs of pathogenicity. Coagulase-negative staphylococci, isolated from various animals and humans, had resistance to oxacillin, benzylpenicillin and the ability to form biofilms, and also had the corresponding genes in their structure (mec A, ica AB, ica D) in 3.3 % of cases. Staphylococci, isolated from different animals and humans, were able to form a biofilm and had the appropriate set of genes (ica D, ica AB) in 5.6 % of cases.

Bovine leukemia virus (BLV) causes significant economic losses for cattle production. We report on an indirect optical method for the BLV detection, based on ultraviolet and visible photoluminescence of zinc oxide (ZnO) nanoparticles. High sensitivity and wide dynamic range of the biosensor from 0.001mg/ml to 1mg/ml of leucosis antibody was shown. The created immune biosensor fully meets the requirements for field use. Our results will be useful for further experiments on novel biosensors development.
