New deadly strain of bird flu may have emerged

“Experts are concerned about the spread of a new strain of bird flu that has already killed one woman in China,” BBC News reports. The new strain, which has evolved from an existing bird flu virus called H10N8, has infected two people in China. A case report in The Lancet medical journal warns that potential for a new pandemic “should not be underestimated”. Their genetic tests of the strain suggests it has adapted to infect humans more easily.  That said, experts suggest there is currently no cause for alarm. There is no evidence that the new strain can pass between humans. Also, the woman who died of the new strain had pre-existing health conditions, including heart disease and high blood pressure, which may have made her more vulnerable to the effects of infection. And for people living in the UK, the risk of contracting bird flu is extremely low. The UK became officially free of bird flu in 2008. It is likely that the Chinese authorities will closely monitor the situation to assess whether there is a potential for a new pandemic to emerge.   What is bird flu? Bird flu, or avian flu, is an infectious viral illness that spreads among birds. In rare cases it can affect humans. It is usually spread to humans by close and prolonged contact with infected birds. Symptoms are the same as seasonal flu but there is a risk that an infected individual can develop complications, such as pneumonia, which can be fatal.  The...

In this study, we applied the Protection Motivation Theory to identify factors influencing farmer intention to undertake biosecurity management strategies. A survey was carried out between 2015 and 2016 across 101 Vietnamese farmers in three locations in Australia: the Northern Territory, South Australia, and Western Australia. Following data analysis using factor analysis and stepwise regressions, the results showed that farmer self-efficacy of on-farm risk management strategies, available incentives, and belief in biosecurity threats associated, positively, with the intention to adopt biosecurity risk management strategi...

Conclusion: We found a high rate of hyperuricemia in children with DS that equally affects both genders, except in the age range of 13-15 years, in which it was more common among females.RESUMEN Introducci ón: Pacientes con síndrome de Down (SD) perecen tener mayor grado de hiperuricemia, aunque hay pocos estudios que traten esa cuestión. Niveles elevados de ácido úrico (AU) son un factor de riesgo independiente para enfermedad cardiovascular aterosclerótica. Objetivo: Estudiar la prevalencia d e hiperuricemia en niños y adolescentes con SD y su distribución de acuerd...

Discussion: These two cases demonstrate that singles vaccination is not an absolute protection against varicella zoster virus–related acute retinal necrosis. However, such vaccination may reduce the severity of the acute retinal necrosis.

Authors: Spagnuolo A, Gridelli C Abstract Introduction: In recent years, immunotherapy has become an integral part of the treatment of many cancers, including non-small cell lung cancer (NSCLC). Precious therapeutic weapons impacting survival are monoclonal antibodies directed against the programmed death protein-1 (PD-1)/programmed death ligand-1 (PD-L1) immune checkpoint. Areas covered: Unfortunately, not all patients treated with checkpoint inhibitors have durable clinical responses. However, a better understanding of the complexity of interactions between the immune system and cancer, the latter capable of adop...

Publication date: Available online 22 May 2019Source: Microbial PathogenesisAuthor(s): Jing Zhao, Changqing Liu, Jiaojiao Zhang, Xiuying Huang, Guozhong ZhangAbstractTo investigate cytokine expression in chicken embryo fibroblast (CEF) cells, a virulent avian avulavirus 1 (AAvV-1) strain called SG10 that rapidly causes 100% mortality in its host, and a vaccine strain (La Sota) were characterized. Real-time quantitative PCR was performed on RNA samples from CEF cells, which were collected at 0, 24, 48 and 72 h post-infection. The dynamic expression patterns of ten cytokines (TNF-α, IFN-α, IFN-β, IL-1&beta...
