Alveolar echinococcosis and cystic echinococcosis are severe zoonotic diseases caused by Echinococcus multilocularis and Echinococcus granulosus s.l. in Europe. To present knowledge, in the European continent, the most important definitive hosts of these parasites belong to the Canidae family. The golden jackal as an opportunistic mesopredator frequently preys on rodents including arvicolids and other easily available food resources, such as viscera and other carrion. By these reasons, the golden jackal can promote the maintenance of both Echinococcus multilocularis and Echinococcus granulosus s.l. Our investigation was conducted in the southwestern part of Hungary where one of the densest golden jackal populations exists. We examined altogether 173 golden jackal small intestines to determine the presence of Echinococcus multilocularis and Echinococcus granulosus s.l. After the molecular diagnostic procedure, we found 27 Echinococcus multilocularis-positive (prevalence: 15.6%; mean intensity: 664 worms) and three Echinococcus granulosus s.l. infected hosts (prevalence: 1.7%; mean intensity: 554.3 worms). We suggest the invasion of the golden jackal in Europe can enhance the spread of both Echinococcus multilocularis and Echinococcus granulosus s.l. This novel epidemiological situation can influence the geographical distribution of these helminths and the characteristics of their endemic in different host species, as well as in humans.

is a parasite prevalent in the temperate regions of the vast Palearctic realm, including Iran. In this study, we investigated infection in road-killed animals and carcasses in northern and northeastern Iran by artificial digestion. We assessed species identification and intraspecific genetic diversity using the markers 5S ribosomal DNA intergenic spacer (5S rDNA), internal transcribed spacer I (ITS1), and cytochrome oxidase subunit I ().

Article Synopsis
- Dirofilariosis is a parasite disease caused by Dirofilaria species, mainly affecting wild carnivores and raising concerns about animal health and potential transmission to domestic dogs and humans.
- In a study in Croatia, researchers examined wild carnivores, finding D. immitis in 6.5% of golden jackals, but none in red foxes or European badgers.
- Infected jackals showed varying parasite loads and possible health impacts, highlighting the need for further research on their role as potential infection reservoirs for other species.

Article Synopsis
- Accurate in-hospital mortality prediction after percutaneous coronary intervention (PCI) is essential for medical decisions, and machine learning techniques can significantly improve prognosis accuracy.
- A study analyzed data from 4,677 patients, using various advanced ML methods, including boosting techniques, for predicting mortality risks after primary PCI in acute ST-elevation myocardial infarction cases.
- The results indicated that hybrid models, especially those using Extreme Gradient Boosting optimized with Bald Eagle Search, had higher accuracy than traditional GRACE scores, suggesting a promising advancement in patient risk assessment following PCI.
