Edward Burtynsky : Works from Two Decades 1981-2001 : A Gift to the Collection
No full textCatalogue produced by the Kitchener-Waterloo Art Gallery on the occasion of an exhibition of 53 works given to the institution by Burtynsky. Roenisch's descriptive analysis underscores relations between nature, people and industry in the artist's large-scale photographs. The author draws attention to how the work raises questions concerning notions of beauty, the ethical position of the photographer, and the contradiction of aestheticizing the abject.

HPV testing as a triage for borderline or mild dyskaryosis on cervical cytology: results from the Sentinel Sites study
No full textbackground: Earlier pilot studies of human papillomavirus (HPV) triage concluded that HPV triage was feasible and cost-effective. The aim of the present study was to study the impact of wider rollout of HPV triage for women with low-grade cytology on colposcopy referral and outcomes.methods: Human papillomavirus testing of liquid-based cytology (LBC) samples showing low-grade abnormalities was used to select women for colposcopy referral at six sites in England. Samples from 10 051 women aged 25–64 years with routine call or recall cytology reported as borderline or mild dyskaryosis were included.results: Human papillomavirus-positive rates were 53.7% in women with borderline cytology and 83.9% in those with mild dyskaryosis. The range between sites was 34.8–73.3% for borderline cytology, and 73.4–91.6% for mild dyskaryosis. In the single site using both LBC technologies there was no difference in rates between the two technologies. The positive predictive value of an HPV test was 16.3% for CIN2 or worse and 6.1% for CIN3 or worse, although there was considerable variation between sites.conclusion: Triaging women with borderline cytological abnormalities and mild dyskaryosis with HPV testing would allow approximately a third of these women to be returned immediately to routine recall, and for a substantial proportion to be referred for colposcopy without repeat cytology. Variation in HPV-positive rates results in differing colposcopy workload
Cost and logistics of alternative roll-out options for implementing human papillomavirus testing as a triage in cervical screening: results of the sentinel sites study.
No full textBACKGROUND: Previous studies have indicated that human papillomavirus (HPV) testing as a triage for managing equivocal cytology is cost-effective. The aim of this study was to assess the costs of alternative roll-out options. METHODS: Detailed cost estimates were collected from six laboratories where HPV triage had been implemented. Costs were assessed for the two different service delivery models that were implemented; a 'hub and spoke model' of central HPV testing in a microbiology laboratory with separate cytology laboratories, and an 'integrated model' where HPV testing was conducted within the cytology laboratory. RESULTS: Comparison of alternative delivery models indicated that setting up HPV processing within existing cytology laboratory, i.e., an 'integrated cytology/HPV laboratory' generated savings in staff time amounting to between £2.54 and 4.86 per sample processed. Running full HPV testing batches was also an important consideration. For full batches to be run on a twice weekly basis requires having no more than two laboratories per Strategic Health Authority. CONCLUSIONS: To be cost-efficient, and to meet turn-around times, HPV testing needs to be conducted at integrated cytology/HPV testing centres with sufficient throughput to run full batches of HPV tests
