Recombinant LSDV Strains in Asia: Vaccine Spillover or Natural Emergence?

From 2017 to 2019, several vaccine-like recombinant strains of lumpy skin disease virus (LSDV) were discovered in Kazakhstan and neighbouring regions of Russia and China. Shortly before their emergence, the authorities in Kazakhstan launched a mass vaccination campaign with the Neethling-based Lumpivax vaccine. Since none of the other countries in the affected region had used a homologous LSDV vaccine, it was soon suspected that the Lumpivax vaccine was the cause of these unusual LSDV strains. In this study, we performed a genome-wide molecular analysis to investigate the composition of two Lumpivax vaccine batches and to establish a possible link between the vaccine and the recent outbreaks. Although labelled as a pure Neethling-based LSDV vaccine, the Lumpivax vaccine appears to be a complex mixture of multiple CaPVs. Using an iterative enrichment/assembly strategy, we obtained the complete genomes of a Neethling-like LSDV vaccine strain, a KSGP-like LSDV vaccine strain and a Sudan-like GTPV strain. The same analysis also revealed the presence of several recombinant LSDV strains that were (almost) identical to the recently described vaccine-like LSDV strains. Based on their InDel/SNP signatures, the vaccine-like recombinant strains can be divided into four groups. Each group has a distinct breakpoint pattern resulting from multiple recombination events, with the number of genetic exchanges ranging from 126 to 146. The enormous divergence of the recombinant strains suggests that they arose during seed production. The recent emergence of vaccine-like LSDV strains in large parts of Asia is, therefore, most likely the result of a spillover from animals vaccinated with the Lumpivax vaccine.     

Cancer morbidity of residents living near an oil refinery plant in North-West Italy

Cerano is a municipality of the Province of Novara (North-West Italy). To assess the morbidity associated to its proximity to a petrochemical plant, standardized incidence ratios (SIRs) of oncological pathologies in the period 2003–2009 were calculated based on age-sex specific rates for the district of the Local Health Authority of Novara (ASL13) and the main regional city of Turin. For all cancers combined, men showed a significant higher risk (SIR: 1.21; 95% CI: 1.02–1.40) compared to the ASL13 population; significantly lower risks for both men and women were observed in comparison to the Turin population. Among women, a significant excess of mesothelioma cancers was reported; a significantly higher risk for lympho-haematopoietic pathologies was also observed compared to the Turin population only. Several other cancers have significantly lower rates in Cerano for both men and women. Despite some studies’ limitations, these findings could suggest potential chemical risk factors and need further investigation.     

Effect of alcohol on viral hepatitis and other forms of liver dysfunction

Alcohol is a known hepatotoxic agent, which may exacerbate liver injury caused by other agents. The wide prevalence of alcohol use and abuse in society makes it an important cofactor in many other liver diseases. Examples of liver diseases that are significantly influenced by ingestion of alcohol include chronic viral hepatitis, disorders of iron overload, and obesity-related liver disease.     

Prognostic factors in acute pancreatitis.

The assessment of the severity of acute pancreatitis (AP) is a critical early step in its management, as severity of AP predicts prognosis. A range of options are available for assessment of severity in AP, including clinical evaluation, standardized prognostic criteria, computed tomography (CT), and biochemical markers. Clinical assessment has limited accuracy for predicting severity early in the course of AP. Therefore, additional assessment using biochemical and radiologic criteria in combination with standardized criteria is appropriate to determine severity and prognosis in AP; a strategy emphasizing daily assessment of severity should be used. The APACHE II is the scoring system of choice for evaluating severity in AP, although it remains an imperfect tool. Computed tomographic grading of AP and the development of the CT severity index allow for heightened accuracy in the prediction of severity. C-Reactive protein is the standard for serum marker assessment of severity and prognosis in AP; other markers, including interleukin-6, polymorphonuclear elastase, and trypsinogen activation peptide, hold promise. The focus of this review is to examine the role of diagnostic tests in evaluating severity and predicting prognosis among patients with AP and to provide a diagnostic algorithm for initial management.
