Keel 0.9.0 is better at detecting and warning you about conflicts affecting the key defaults it covers, especially autoupdate policies. It also gives you a heads-up and manual install option for the latest secure update on your branch if you're not on it.

To build semi-automated research and clinical trial watch tools for CMT.blog, I had to decide what terms to use to find and filter the likely most relevant "CMT" information. I'm a lumper, which is useful in cases like this, but without significant splitting you get only the haystack and no needles.

Books have been rich in metadata, good at social media, and made by many hands — scribes, printers, editors, readers in the margins. The lone author is the odd exception, not the rule.

Unfortunately, nerve conduction velocity and amplitude don't map to clinical, physical symptoms, they don't track mobility loss, and they don't have much to do with the lived experience.

Hopefully that limited NCV data will increasingly be supplemented with the results of other test methods, like muscle biopsies and blood tests. Diagnostic tech for CMT is due for big updates and reform.

Nerve conduction studies are still the most common (and often poorly understood) diagnostic tech for CMT and related neuromuscular diseases. They date back to the 1960s-70s. I've had one done annually for quite some time, never on a machine with an edition of Windows newer than Windows ME!
