OpenAI Proposes “Right to AI”
Researchers from OpenAI have put forward an industrial policy for artificial intelligence and it’s quite a read. They propose a legally recognised “Right to AI”, meaning broad public access to powerful systems, backed by government-funded compute resources so researchers, startups, and public institutions can run models themselves, rather than rely on a few companies. To make this reality, they want to see an expansion of electricity supply for data centres by fast-tracking nuclear and renewables. They also suggest a national wealth fund that captures a share of AI-driven profits and redistributes it to citizens, alongside taxes or levies on highly automated systems, effectively a “robot tax”.
Of course none of that has any chance of happening, but OpenAI can now claim they care about the common man.
If uncertain evidence, a “conditional rec” should be made. Or if there is little to no published evidence for the question at hand, rather than “recs” the panel could make “good practice statement”. Leaves rm for sci to evolve. See: sciencedirect.com/science/ar…

Yesterday in @AnnalsofIM, a new risk-stratified analysis found that different people get different benefits from limiting #SaturateFats. Cue the all-or-nothing #FalseDichotomies and another painful assault on the nuance of nutrition science.

#RealWorldData advocates facing challenges addressing sources of bias suggest causal modelling as a solution. Doesn’t work. Comparison of 19 modelling studies with #RCTs showed 42% differed in direction and 47% of confidence intervals didn’t include RCT estimate.

Impressive new Canadian #pediatric #obesity #guidelines are out today. The authors grounded them in the best science and crafted them with values of children and families at the center.
What's missing? Resources to make them real.

Watch the Pennington Biomedical space for new insights on childhood obesity coming from our Implementation Science and Childhood Obesity Symposium. Renowned scientists from the US and Canada are collaborating on a consensus paper to address the current landscape, scalable solutions, and strategies for implementing evidence-based interventions to combat childhood obesity.
Stay tuned for groundbreaking insights into this pressing issue. #ChildhoodObesity #ImplementationScience #PenningtonBiomedical

Have the benefits of statins been overstated?

Like most allied health professions, RDs report not having had enough training in evidence-based practice (and most want more training). Lots of room for uplifting EBP, starting with crdns and krdns (which drive national examinations)! See Table 1: pubmed.ncbi.nlm.nih.gov/3815…

It is no doubt more complicated to do nutrition and health behavior research, starts with a good answerable Q, and needs good methodologists/trialists/infrastructure and other content/ interdisciplinary experts. +$$

The uncertainty will continue until trialists get togeather and conduct multiple studies that measure outcomes that are undoubtedly patient important (eg, mortality, QoL)

We need evidence-based ‘research’, where high quality, original, up to date systematic reviews and guidelines identify the gaps, and drive much needed clinical nutrition trials. And the trials need to measure outcomes that matter to patients and the public
