RESUMEN

AIM: The aim of the study is to identify and map what is known about workplace violence involving midwives in Australia and New Zealand. BACKGROUND: Research from the United Kingdom demonstrates that workplace violence within maternity services is a pervasive issue with significant and wide-ranging clinical, individual and organisational consequences. To date, little is known about this issue within Australian and New Zealand maternity services. EVALUATION: A scoping review, guided by Arksey and O'Malley's framework, was conducted. Reporting followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Just one identified study aimed to explore midwives' experiences of workplace violence. A further nine arrived at related results or themes. KEY ISSUES: Workplace violence is present in a variety of forms across maternity services in Australia and New Zealand. Its prevalence is, however, yet to be understood. Workplace violence causes physical and mental health issues for midwives, premature workforce attrition, and jeopardizes the quality and safety of maternity care. CONCLUSIONS: Workplace violence has been acknowledged as one of the key contributing factors towards premature attrition from the midwifery profession, with new graduate midwives most likely to leave. With the midwifery workforce ageing and evidence of serious clinical implications emerging, workplace violence needs urgent research and organisational attention. IMPLICATIONS FOR NURSING MANAGEMENT: Workplace violence is a key contributing factor towards recruitment and retention challenges for managers. To help tackle this, managers have a key role to play in identifying and effectively addressing workplace violence by acting as positive role models, taking a zero-tolerance approach and fostering collegial relationships. Managers, holding key clinical leadership positions, are pivotal to ensuring all complaints raised are handled with transparency and consistency regardless of one's position within the clinical hierarchy and organisational structure.

RESUMEN

A novel nonnucleoside inhibitor of hepatitis C virus (HCV) RNA-dependent RNA polymerase (RdRp), [(1R)-5-cyano-8-methyl-1-propyl-1,3,4,9-tetrahydropyano[3,4-b]indol-1-yl] acetic acid (HCV-371), was discovered through high-throughput screening followed by chemical optimization. HCV-371 displayed broad inhibitory activities against the NS5B RdRp enzyme, with 50% inhibitory concentrations ranging from 0.3 to 1.8 microM for 90% of the isolates derived from HCV genotypes 1a, 1b, and 3a. HCV-371 showed no inhibitory activity against a panel of human polymerases, including mitochondrial DNA polymerase gamma, and other unrelated viral polymerases, demonstrating its specificity for the HCV polymerase. A single administration of HCV-371 to cells containing the HCV subgenomic replicon for 3 days resulted in a dose-dependent reduction of the steady-state levels of viral RNA and protein. Multiple treatments with HCV-371 for 16 days led to a >3-log10 reduction in the HCV RNA level. In comparison, multiple treatments with a similar inhibitory dose of alpha interferon resulted in a 2-log10 reduction of the viral RNA level. In addition, treatment of cells with a combination of HCV-371 and pegylated alpha interferon resulted in an additive antiviral activity. Within the effective antiviral concentrations of HCV-371, there was no effect on cell viability and metabolism. The intracellular antiviral specificity of HCV-371 was demonstrated by its lack of activity in cells infected with several DNA or RNA viruses. Fluorescence binding studies show that HCV-371 binds the NS5B with an apparent dissociation constant of 150 nM, leading to high selectivity and lack of cytotoxicity in the antiviral assays.
