Dual-vector rAAVrh8 gene therapy for GM2 gangliosidosis: a phase 1/2 trial | Nature Medicine The dual rAAVrh8-HEXA and rAAVrh8-HEXB vector can restore central nervous system hexosaminidase (Hex) enzyme activity, decrease GM2 levels in cerebrospinal fluid and rescue phenotypic consequences of GM2 gangliosidosis, Tay–Sachs and Sandhoff diseases in animal models following simultaneous bi-thalamic (BiT) injections. Following up on an n = 2 expanded access trial, we initiated a phase 1/2, single-dose, dose-escalation of combined BiT, intra-cisterna magna and intrathecal infusion in children with Tay–Sachs and Sandhoff diseases (six infantile, three juvenile). The BiT injection volume and vector dose were doubled between four cohorts, with the lowest dose matching the earlier expanded access trial. Cerebrospinal fluid HexA enzyme activity, serum total Hex activity and GM2 levels showed a dose-dependent biochemical correction of the disease. Serum Hex activity surpassed 40 nmol h−1 ml−1, two times the lower limit of normal, and neuroimaging demonstrated increased fiber tracts. Correc

Abstract New technology brings new methodological opportunities. While long limited to face-to-face interviewing, today’s interview researchers can choose from a plethora of options, including email, instant messaging, telephone, and video interviews. Consequently, the issue of interview modes and their relative strengths and weaknesses has received increased attention. In this article, we take stock of existing writings on interview modes in qualitative interview research. Drawing on key insights from more general theorizing about face-to-face and remote interaction, we identify and challenge five key assumptions in writings about interview modes: (1) that physical copresence ensures more and better data; (2) that interview modes have determinate effects on interaction; (3) that remote interviewing should seek to replicate face-to-face interviewing; (4) that interviews modes should be held constant within each study; and (5) that face-to-face interviewing is unmediated. We counter each assumption with a series of more productive methodological principles and advance instead a view we call interview mode pluralism, which offers a more nuanced and relational understanding of the strengths and weaknesses of different interview modes. The article thus helps increase the methodological literacy of those conducting and evaluating qualitative interview research, enhancing the likelihood that researchers select those tools best suited for their tasks, and reducing the chance that evaluators dismiss research based on their methodological prejudice.

📢 New paper 📢

We bust 5 myths about face-to-face vs. remote interviewing and argue for "interview mode pluralism" as a more context-aware way of assessing the strengths and weaknesses of different interview modes.

Chart showing global greenhouse gas emissions from food production Land use 24% Livestock production 31% Crop production 27% (with 6% as animal feed thus arguably livestock production) Processing 4% Transport 6% Packaging 5% Retail 3% Source: https://ourworldindata.org/food-ghg-emissions

Most food-related emissions are related to livestock and crop production, including land use. Emissions after the food leaves the farm are relatively small. So good to improve efficiency across supply chains wherever possible of course - but be sure to keep the focus on the big stuff. 🧪
