Technology rich learning spaces - opportunities and risks

In this workshop participants explore the potential of the technology rich group learning spaces such as those in Bournemouth University’s SCONUL Library Design Award winning The Sir Michael Cobham Library. The development of these spaces was informed by the research undertaken by Educause1 and the outcomes of Bournemouth’s eRes2,3, which focussed on the pedagogies influencing e-learning with e-resources. Participants will be assigned to groups and each group will be presented with different profiles such as netgen4 and digital immigrant 5. The concept of technology rich learning space will be introduced before the groups engage in a “learning activity” to consider the relationships between technology, space and learning outcomes. The group will then identify and share opportunities and challenges from the student and staff perspective. This workshop was successfully used in November 2008 with Bournemouth University’s PGCert students, who have already begun to incorporate the opportunities presented by technology rich learning spaces into their teaching

Prophylaxis of postoperative endophthalmitis following cataract surgery: Results of the ESCRS multicenter study and identification of risk factors

Purpose: To identify risk factors and describe the effects of antibiotic prophylaxis on the incidence of postoperative endophthalmitis after cataract surgery based on analysis of the findings of the European Society of Cataract & Refractive Surgeons (ESCRS) multicenter study. Setting: Twenty-four ophthalmology units in Austria, Belgium, Germany, Italy, Poland, Portugal, Spain, Turkey, and the United Kingdom. Methods: A prospective randomized partially masked multicenter cataract surgery study recruited 16 603 patients. The study was based on a 2 × 2 factorial design, with intracameral cefuroxime and topical perioperative levofloxacin factors resulting in 4 treatment groups. The comparison of case and non-case data was performed using multivariable logistic regression analyses. Odds ratios (ORs) associated with treatment effects and other risk factors were estimated. Results: Twenty-nine patients presented with endophthalmitis, of whom 20 were classified as having proven infective endophthalmitis. The absence of an intracameral cefuroxime prophylactic regimen at 1 mg in 0.1 mL normal saline was associated with a 4.92-fold increase (95% confidence interval [CI], 1.87-12.9) in the risk for total postoperative endophthalmitis. In addition, the use of clear corneal incisions (CCIs) compared to scleral tunnels was associated with a 5.88-fold increase (95% CI, 1.34-25.9) in risk and the use of silicone intraocular lens (IOL) optic material compared to acrylic with a 3.13-fold increase (95% CI, 1.47-6.67). The presence of surgical complications increased the risk for total endophthalmitis 4.95-fold (95% CI, 1.68-14.6), and more experienced surgeons were more likely to be associated with endophthalmitis cases. When considering only proven infective endophthalmitis cases, the absence of cefuroxime and the use of silicone IOL optic material were significantly associated with an increased risk, and there was evidence that men were more predisposed to infection (OR, 2.70; 95% CI, 1.07-6.8). Conclusions: Use of intracameral cefuroxime at the end of surgery reduced the occurrence of postoperative endophthalmitis. Additional risk factors associated with endophthalmitis after cataract surgery included CCIs and the use of silicone IOLs. © 2007 ASCRS and ESCRS
