Does quality of life among breast cancer survivors one year after diagnosis differ depending on urban and non-urban residence? A comparative study

Background: This study examined the quality of life (QOL), measured by the Functional Assessment of Cancer Therapy (FACT) questionnaire, among urban (n=277) and non-urban (n=323) breast cancer survivors and women from the general population (n=1140) in Queensland, Australia. ---------- Methods: Population-based samples of breast cancer survivors aged <75 years who were 12 months post-diagnosis and similarly-aged women from the general population were recruited between 2002 and 2007. ---------- Results: Age-adjusted QOL among urban and non-urban breast cancer survivors was similar, although QOL related to breast cancer concerns was the weakest domain and was lower among non-urban survivors than their urban counterparts (36.8 versus 40.4, P<0.01). Irrespective of residence, breast cancer survivors, on average, reported comparable scores on most QOL scales as their general population peers, although physical well-being was significantly lower among non-urban survivors (versus the general population, P<0.01). Overall, around 20%-33% of survivors experienced lower QOL than peers without the disease. The odds of reporting QOL below normative levels were increased more than two-fold for those who experienced complications following surgery, reported upper-body problems, had higher perceived stress levels and/or a poor perception of handling stress (P<0.01 for all). ---------- Conclusions: Results can be used to identify subgroups of women at risk of low QOL and to inform components of tailored recovery interventions to optimize QOL for these women following cancer treatment.

Innovation in clinical learning for the acute hospital environment : nursing grand rounds

The literature reports that workload factors affect nurses' ability to fully engage in continuing professional development. Hence the work environment in acute care calls for innovative approaches to achieve continuous development of nursing practice and work satisfaction. This study employs a one group pre-test post-test design to test the effectiveness of nursing grand rounds on nursing worklife satisfaction and work environment in an acute surgical ward. The effect of nursing grand rounds was measured using the Nursing Worklife Satisfaction Scale and the Practice Environment Scale. There was no change between pre- and post-test on these measures but trends were evident in some component scores. Statistical results were inconclusive but observational data indicated that nursing grand rounds was found to be feasible, well attended with tested processes for implementation in an acute care environment.

The life-history and relationships of ‘Orthocladius’ pictipennis Freeman (Diptera: Chironomidae)

The previously unknown larva and pupa of ‘Orthocladius’ pictipennis Freeman have been found, and associated by molecular means. Pharate pupae (males within pupae) allow the link to the described adult. We describe the larva and pupa, and provide short notes on the adult. The taxon is unrelated to Orthocladius – no members of this Holarctic genus are present in New Zealand – and therefore we provide a new generic name, Paulfreemania Cranston and Krosch gen. n. as well as a short discussion of relationships amongst austral Orthocladiinae.

Towards informed learning: Snapshots of a Fulbright Scholar-in-Residence program in Denver

This paper outlines the Fulbright Scholar-in-Residence (SIR) program that I undertook at University of Colorado in Denver, USA, in August-December 2010. It explains how the SIR program proved a most enriching experience for me, professionally and personally. One reason for this paper is to encourage other LIS professionals and educators to apply for Fulbrights and other types of scholarships and exchange programs. And also to reinforce the message that research and further study really can open doors and enrich our professional careers.

Residence time investigation in a co-axial dielectric barrier discharge reactor

The residence time distribution (RTD) is a crucial parameter when treating engine exhaust emissions with a Dielectric Barrier Discharge (DBD) reactor. In this paper, the residence time of such a reactor is investigated using a finite element based software: COMSOL Multiphysics 4.3. Non-thermal plasma (NTP) discharge is being introduced as a promising method for pollutant emission reduction. DBD is one of the most advantageous of NTP technologies. In a two cylinder co-axial DBD reactor, tubes are placed between two electrodes and flow passes through the annuals between these barrier tubes. If the mean residence time increases in a DBD reactor, there will be a corresponding increase in reaction time and consequently, the pollutant removal efficiency can increase. However, pollutant formation can occur during increased mean residence time and so the proportion of fluid that may remain for periods significantly longer than the mean residence time is of great importance. In this study, first, the residence time distribution is calculated based on the standard reactor used by the authors for ultrafine particle (10-500 nm) removal. Then, different geometrics and various inlet velocities are considered. Finally, for selected cases, some roughness elements added inside the reactor and the residence time is calculated. These results will form the basis for a COMSOL plasma and CFD module investigation.
