'What research was carried out on this vaginal mesh?' Health-related concerns in women following mesh-augmented prolapse surgery: a thematic analysis.

OBJECTIVE: To understand health-related issues in women following mesh-augmented prolapse surgery. DESIGN: Inductive thematic analysis of free-text comments from participants in a cross-sectional study of laparoscopic mesh sacrohysteropexy. SETTING: Tertiary urogynaecology centres, United Kingdom. POPULATION: Women who underwent laparoscopic mesh sacrohysteropexy by surgeons based at two tertiary urogynaecology centres between 2010 and 2018. METHODS: A total of 1766 potential participants were contacted by post and invited to complete paper, online or telephone questionnaires containing a free-text comments section. Of 1121 participants (response proportion 63.5%), 752 (67.1%) provided such comments. These were analysed with a six-stage inductive thematic analysis, using NVivo 11® software. MAIN OUTCOME MEASURES: Themes developed from free-text comments. RESULTS: Following familiarisation, 29 codes and 189 sub-codes were identified. These defined six themes: pelvic floor symptoms, health status, treatment success, mesh, pain and care received. The majority of comments centred on the first of these six themes. There were concerns about mesh use and a desire for more information. A range of pain symptoms were mentioned, often associated with pelvic floor symptoms, prolapse surgery or mesh. CONCLUSIONS: Despite the mesh controversy, pelvic floor symptoms and their impact on quality of life remain the principle concern of women following mesh-augmented prolapse surgery. There is a need for quality, accessible and evidence-based information sources for those women with concerns, and for those considering such surgery in the future, particularly regarding mesh safety and postoperative recovery. The relationships between pain, prolapse, mesh and pelvic floor surgery require further study. TWEETABLE ABSTRACT: Following mesh-augmented prolapse surgery, pelvic floor symptoms remain women's main focus; pain deserves further research.

Evaluating temporal patterns of metals concentrations in floodplain lakes of the Athabasca Delta (Canada) relative to pre-industrial baselines.

Sediment quality monitoring is widely used to quantify extent of river pollution, but requires knowledge of pre-disturbance conditions in the potentially altered landscape. This has long been identified as a critical aspect to develop for addressing concerns of river pollution in the Alberta Oil Sands Region. Here, we use analyses of sediment cores from eight floodplain lakes spanning a 67 river-km transect across the Athabasca Delta to define pre-1920 (pre-industrial) baseline concentrations for vanadium and five primary pollutants. We then evaluate if sediment metals concentrations have become enriched above baseline since onset of oil sands development and other industrial activities. Results demonstrate no enrichment of metals concentrations (except zinc at one lake) and absence of consistent temporal increases above pre-industrial baselines. Thus, natural processes continue to dominate metal deposition in floodplain lakes of the Athabasca Delta -- an important finding to inform stewardship decisions. The pre-1920 metals concentrations baselines offer a useful tool for ongoing sediment monitoring in aquatic ecosystems of the Athabasca Delta.

Clinically stationary choroidal melanoma with extraocular extension.

A malignant melanoma of the choroid was observed for three years because of an erroneous diagnosis of disciform macular degeneration. No lateral or vertical growth was noted during the observation period, but significant extrascieral extension was discovered at the time of radioactive phosphorus uptake test and enucleation.
