Pathogenicity of PMV-3/Turkey/England/Midland poultry holdings/1981 for chickens and turkeys

The original 1981 English isolate of avian paramyxovirus type 3 from turkeys was of higher pathogenicity to chickens than the prototype 1968 isolate turkey/Wisconsin. It was lethal to chicks aged one day when given by intravenous or intracerebral inoculation. The age susceptibility was increased to one week by use of an inbred strain or betamethasone. The virus was more pathogenic to its natural host as outbred turkeys aged one week died after intravenous inoculation of the virus and contact transmission resulted in stunting and seroconversion of 2-week-old birds. Monoclonal antibodies to both viral glycoproteins, but not to the two internal proteins, protected one-day-old turkeys from 1000 intravenous LD50 of virus when they were inoculated one day after virus. This was considered to be analogous to maternally derived immunity and emphasised the role of yolk sac antibody in the protection of young stock.     

Differences in Perceived Severity of Zika Virus Infection and Dengue Fever and its Influence on Mosquito Control Practices in Malaysia

The aims of this study were to explore the differences in (1) the perception of severity towards ZIKV infection and dengue fever, and (2) mosquito control practices before and after the ZIKV outbreak were declared a Public Health Emergency of International Concern (PHEIC). Data were collected between Feb to May 2016 using a computer-assisted telephone interviewing system. The median scale score for perceived severity of ZIKV was 3 (interquartile range [IQR] 1–5) versus 4 (IQR 3–5) for dengue (P?<?0.001). The scores for mosquito control practices before and after ZIKV was declared a PHEIC were similar, at 4 (IQR 3–5). Multivariate analysis revealed that participants with a higher score for perception of severity of ZIKV were more likely to report greater mosquito control practices after the declaration of the PHEIC (OR 1.822 [95% CI 1.107–2.998]). The emerging ZIKV pandemic requires concerted efforts to enhance mosquito control practices among the Malaysian public. Efforts to improve public mosquito control practices should focus on enhancing the perception of the severity of ZIKV.     

Quality of life in Palestinian patients with end-stage renal disease receiving treatment by haemodialysis: a cross-sectional study

Background

Haemodialysis is a life-saving but burdensome therapy for patients with end-stage renal disease, which can substantially impair health-related quality of life (HRQOL) and outcomes. The aim of this study was to determine the patterns of HRQOL and to identify the risk factors for reduced HRQOL in Palestinian patients receiving treatment by haemodialysis.
