BACKGROUND AND OBJECTIVE: Human research ethics committees provide essential review of research projects to ensure the ethical conduct of human research. Several recent reports have highlighted a complex process for successful application for human research ethics committee approval, particularly for multi-centre studies. Limited resources are available for the execution of human clinical research in Australia and around the world.
METHODS: This report overviews the process of ethics approval for a National Health and Medical Research Council-funded multi-centre study in Australia, focussing on the time and resource implications of such applications in 2007 and 2008.
RESULTS: Applications were submitted to 16 hospital and two university human research ethics committees. The total time to gain final approval from each committee ranged between 13 and 77 days (median = 46 days); the entire process took 16 months to complete and the research officer's time was estimated to cost $A34 143.
CONCLUSIONS: Obstacles to timely human research ethics committee approval are reviewed, including recent, planned and potential initiatives that could improve the ethics approval of multi-centre research.

TITLE: 'Every pregnant woman needs a midwife'-the experiences of HIV affected women in Northern Ireland.
OBJECTIVE: to explore HIV positive women's experiences of pregnancy and maternity care, with a focus on their interactions with midwives.
DESIGN: a prospective qualitative study.
SETTING: regional HIV unit in Northern Ireland.
PARTICIPANTS: 22 interviews were conducted with 10 women at different stages of their reproductive trajectories.
FINDINGS: the pervasive presence of HIV related stigma threatened the women's experience of pregnancy and care. The key staff attributes that facilitated a positive experience were knowledge and experience, empathy and understanding of their unique needs and continuity of care.
KEY CONCLUSIONS: pregnancy in the context of HIV, whilst offering a much needed sense of normality, also increases woman's sense of anxiety and vulnerability and therefore the need for supportive interventions that affirm normality is intensified. A maternity team approach, with a focus on providing 'balanced care' could meet all of the woman and child's medical needs, whilst also emphasising the normalcy of pregnancy.

Bioresorbable polymers such as PLA have an important role to play in the development of temporary implantable medical devices with significant benefits over traditional therapies. However, development of new devices is hindered by high manufacturing costs associated with difficulties in processing the material. A major problem is the lack of insight on material degradation during processing. In this work, a method of quantifying degradation of PLA using IR spectroscopy coupled with computational chemistry and chemometric modeling is examined. It is shown that the method can predict the quantity of degradation products in solid-state samples with reasonably good accuracy, indicating the potential to adapt the method to developing an on-line sensor for monitoring PLA degradation in real-time during processing.

Punctal plugs (PPs) are miniature medical implants that were initially developed for the treatment of dry eyes. Since their introduction in 1975, many PPs made from different materials and designs have been developed. PPs, albeit generally successful, suffer from drawbacks such as epiphora and suppurative canaliculitis. To overcome these issues intelligent designs of PPs were proposed (e.g. SmartPLUG™ and Form Fit™). PPs are also gaining interest among pharmaceutical scientists for sustaining drug delivery to the eye. This review aims to provide an overview of PPs for dry eye treatment and drug delivery to treat a range of ocular diseases. It also discusses current challenges in using PPs for ocular diseases.
