'Far isn't Far': Shetland on the internet

This paper examines various websites based in the Shetland Islands, on Britain’s northern periphery. These sites focus on local life and culture and, by enabling interactive contribution, provide an extension of the social networks existing in the physical locations of the Islands. So rather than emphasising the separation of the virtual and physical realms, they enable a hybrid space, in which interactions within the virtual space enhance and accentuate the appreciation of physical locations within Shetland, and the social relationships based there. Therefore they focus users’ attention on the Islands as a specific and distinctive community. However, they are also embedded within the wider virtual landscape of the internet. Thus, through the use of these sites, perceptions of the local and peripheral continually oscillate with ideas of the globally connected. They enable users to perceive Shetland as a place that exists at many points on an axis of peripherality and connectedness. Ultimately, they enable a continuation, but also complication of an historical process, in which communal narratives of cultural identity and collective memory have been continually informed and reformed by the dialogue between Shetland communities and the wider world through the structures of mass communication

Two Phase 3 Trials of Gantenerumab in Early Alzheimer's Disease

Background: Monoclonal antibodies that target amyloid-beta (Aβ) have the potential to slow cognitive and functional decline in persons with early Alzheimer's disease. Gantenerumab is a subcutaneously administered, fully human, anti-Aβ IgG1 monoclonal antibody with highest affinity for aggregated Aβ that has been tested for the treatment of Alzheimer's disease. Methods: We conducted two phase 3 trials (GRADUATE I and II) involving participants 50 to 90 years of age with mild cognitive impairment or mild dementia due to Alzheimer's disease and evidence of amyloid plaques on positron-emission tomography (PET) or cerebrospinal fluid (CSF) testing. Participants were randomly assigned to receive gantenerumab or placebo every 2 weeks. The primary outcome was the change from baseline in the score on the Clinical Dementia Rating scale-Sum of Boxes (CDR-SB; range, 0 to 18, with higher scores indicating greater cognitive impairment) at week 116. Results: A total of 985 and 980 participants were enrolled in the GRADUATE I and II trials, respectively. The baseline CDR-SB score was 3.7 in the GRADUATE I trial and 3.6 in the GRADUATE II trial. The change from baseline in the CDR-SB score at week 116 was 3.35 with gantenerumab and 3.65 with placebo in the GRADUATE I trial (difference, -0.31; 95% confidence interval [CI], -0.66 to 0.05; P = 0.10) and was 2.82 with gantenerumab and 3.01 with placebo in the GRADUATE II trial (difference, -0.19; 95% CI, -0.55 to 0.17; P = 0.30). At week 116, the difference in the amyloid level on PET between the gantenerumab group and the placebo group was -66.44 and -56.46 centiloids in the GRADUATE I and II trials, respectively, and amyloid-negative status was attained in 28.0% and 26.8% of the participants receiving gantenerumab in the two trials. Across both trials, participants receiving gantenerumab had lower CSF levels of phosphorylated tau 181 and higher levels of Aβ42 than those receiving placebo; the accumulation of aggregated tau on PET was similar in the two groups. Amyloid-related imaging abnormalities with edema (ARIA-E) occurred in 24.9% of the participants receiving gantenerumab, and symptomatic ARIA-E occurred in 5.0%. Conclusions: Among persons with early Alzheimer's disease, the use of gantenerumab led to a lower amyloid plaque burden than placebo at 116 weeks but was not associated with slower clinical decline.
